Cabozantinib for Adults With Advanced Soft Tissue Sarcoma

Background:

- Cabozantinib is a cancer treatment drug that blocks the growth of new blood vessels in tumors. It can also block a chemical on tumor cells that allows the cells to grow. A similar drug, pazopanib, is used to treat types of cancer known as sarcomas. Researchers want to see if cabozantinib can be an effective treatment for types of soft tissue sarcoma that have not responded to earlier treatments.

Objectives:

- To test the effectiveness of cabozantinib for soft tissue sarcomas that have not responded to standard treatments.

Eligibility:

- Individuals at least 18 years of age who have soft tissue sarcomas that have not responded to standard treatments.

Design:

- Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment.

- Participants will take cabozantinib tablets daily for 28-day cycles of treatment. The tablets should be taken whole on an empty stomach.

- Treatment will be monitored with frequent blood tests and imaging studies.

- Participants will continue to take cabozantinib for as long as the tumor does not become worse and the side effects are not too severe.

Eligibility


- INCLUSION CRITERIA:

   - Patients must have histologically or cytologically confirmed soft tissue sarcoma that
   is metastatic or unresectable and for which standard treatment that prolongs survival
   does not exist or is no longer effective.

   - Patients must have measurable disease, defined as at least one lesion that can be
   accurately measured in at least one dimension (longest diameter to be recorded for
   non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional
   techniques or as >10 mm with spiral CT scan, MRI, or calipers by clinical exam.

   - Patients are allowed prior VEGFR-TKI therapy. Patients will be stratified based on
   prior VEGFR-TKI therapy.

   - Age greater than or equal to 18 years. Because no dosing or adverse event data are
   currently available on the use of cabozantinib in patients <18 years of age, children
   are excluded from this study.

   - ECOG performance status less than or equal to 1 (Karnofsky >70%).

   - Life expectancy > 3 months.

   - Patients must have normal organ and marrow function as defined below:

      - leukocytes greater than or equal to 3,000/mcL

      - absolute neutrophil count greater than or equal to 1,500/mcL

      - platelets greater than or equal to 100,000/mcL

      - total bilirubin less than or equal to 1.5 times ULN

      - AST(SGOT)/ALT(SGPT) less than or equal to 2.5 times institutional upper limit of
      normal creatinine within normal institutional limits

OR

   - creatinine clearance greater than or equal to 60 mL/min/1.73 m(2) for patients with
   creatinine levels above institutional normal.

   - hemoglobin greater than or equal to 9 g/dL

   - serum albumin greater than or equal to 2.8g/dL

   - lipase <2.0 times ULN and no radiologic or clinical evidence of pancreatitis

   - urine protein/creatinine ratio (UPCR) less than or equal to 1

   - serum phosphorus calcium, magnesium and potassium greater than or equal to LLN

      - Subjects must have blood pressure (BP) no greater than 140 mmHg (systolic) and 90
      mmHg (diastolic) for eligibility. Initiation or adjustment of BP medication is
      permitted prior to study entry provided that the average of three BP readings at
      the time of enrollment is less than or equal to 140/90 mmHg

      - Patients must be able to swallow whole tablets. Tablets must not be crushed or
      chewed.

      - The effects of cabozantinib on the developing human fetus are unknown. For this
      reason and because receptor tyrosine kinases are known to be teratogenic, women
      of child-bearing potential and men must agree to use adequate contraception. All
      subjects of reproductive potential must agree to use both a barrier method and a
      second method of birth control during the course of the study and for 4 months
      after the last dose of study drug(s).

Sexually active subjects (men and women) must agree to use medically accepted barrier
methods of contraception (e.g., male or female condom) during the course of the study and
for 4 months after the last dose of study drug(s), even if oral contraceptives are also
used.

-Ability to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

   - Patients who have had anticancer therapy, including kinase inhibitors or any
   investigational agent within 4 weeks or 5 half-lives (whichever is shorter) (6 weeks
   for nitrosoureas or mitomycin C) prior to entering the study or those who have not
   recovered to baseline from adverse events (except alopecia and other non-clinically
   significant AEs). Patients who have received prior cabozantinib or inhibitors of c-MET
   or HGF are ineligible.

   - The subject has received radionuclide treatment within 6 weeks of the first dose of
   study treatment

   - The subject has received radiation therapy within 4 weeks (greater than or equal to 2
   weeks for palliative radiation therapy)

   - Patients with active brain metastases or carcinomatous meningitis or epidural disease
   are excluded from this clinical trial. Subjects with brain metastases previously
   treated with whole brain radiation or radiosurgery or subjects with epidural disease
   previously treated with radiation who are asymptomatic and have remained stable for 4
   weeks and do not require steroid treatment for at least 2 weeks before starting study
   treatment are eligible. Neurosurgical resection of brain metastases or brain biopsy is
   permitted if completed at least 3 months before starting study treatment. Baseline
   brain imaging with contrast-enhanced CT or MRI scans for subjects with known brain
   metastases is required to confirm eligibility.

   - Eligibility of subjects receiving any medications or substances known to affect or
   with the potential to affect the activity of cabozantinib will be determined following
   review of their cases by the Principal Investigator. Patients who are taking
   enzyme-inducing anticonvulsant agents are not eligible.

   - Patients with refractory nausea and vomiting, chronic gastrointestinal diseases (e.g.,
   inflammatory bowel disease), or significant bowel resection that could interfere with
   absorption.

   - Uncontrolled intercurrent illness including, but not limited to symptomatic congestive
   heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric
   illness/social situations that would limit compliance with study requirements.

   - Pregnant women are excluded from this study because cabozantinib has the potential for
   teratogenic or abortifacient effects. Because there is an unknown but potential risk
   for adverse events in nursing infants secondary to treatment of the mother with
   cabozantinib, breastfeeding should be discontinued if the mother is treated with
   cabozantinib.

   - Strong inhibitors and inducers of CYP3A4 can affect levels of cabozantinib and should
   be avoided whenever possible or switched to alternatives. Subjects requiring chronic
   concomitant treatment of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin,
   carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John s Wort)
   are not eligible for this study. Because the lists of these agents are constantly
   changing, it is important to regularly consult a frequently-updated list such as
   http://medicine.iupui.edu/clinpharm/ddis/; medical reference texts such as the
   Physicians Desk Reference may also provide this information. As part of the
   enrollment/informed consent procedures, the patient will be counseled on the risk of
   interactions with other agents, and what to do if new medications need to be
   prescribed or if the patient is considering a new overthe-counter medicine or herbal
   product.

   - HIV-positive patients on combination antiretroviral therapy are ineligible because of
   the potential for pharmacokinetic interactions with cabozantinib. Appropriate studies
   will be undertaken in patients receiving combination antiretroviral therapy when
   indicated.

   - The subject requires concomitant treatment, in therapeutic doses, with anticoagulants
   such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa
   inhibitors, or antiplatelet agents (e.g., clopidogrel). Low dose aspirin (less than or
   equal to 81 mg/day), low-dose warfarin (less than or equal to 1 mg/day), and
   prophylactic low molecular weight heparin (LMWH) are permitted. (Please note that
   there may be cases in which patients on study require anticoagulation for DVT/PE
   management; this does not necessitate taking

the patient off study.)

   - The subject has experienced any of the following

      - clinically-significant gastrointestinal bleeding within 6 months before the first
      dose of study treatment

      - hemoptysis of greater than or equal to 0.5 teaspoon (2.5 mL) of red blood within
      3 months before the first dose of study treatment

      - any other signs indicative of pulmonary hemorrhage within 3 months before the
      first dose of study treatment

   - The subject has radiographic evidence of cavitating pulmonary lesion(s).

   - The subject has tumor in contact with, invading, or encasing any major blood vessels

         systolic, or > 90 mm Hg diastolic despite optimal antihypertensive treatment
         within 7 days of the first dose of study treatment

         3. Any history of congenital long QT syndrome

         4. Any of the following within 6 months before the first dose of study
         treatment:

            - unstable angina pectoris

            - clinically-significant cardiac arrhythmias

            - stroke (including TIA, or other ischemic event)

            - myocardial infarction

            - thromboembolic event requiring therapeutic anticoagulation (Note:
            subjects with a venous filter (e.g. vena cava filter) are not eligible
            for this study)

      2. Gastrointestinal disorders particularly those associated with a high risk of
      perforation or fistula formation including:

         1. Any of the following within 28 days before the first dose of study treatment

            - intra-abdominal tumor/metastases invading GI mucosa

            - active peptic ulcer disease,

   accurately measured in at least one dimension (longest diameter to be recorded for
   non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional
   techniques or as >10 mm with spiral CT scan, MRI, or calipers by clinical exam.

   - Patients are allowed prior VEGFR-TKI therapy. Patients will be stratified based on
   prior VEGFR-TKI therapy.

   - Age greater than or equal to 18 years. Because no dosing or adverse event data are
   currently available on the use of cabozantinib in patients <18 years of age, children
   are excluded from this study.

   - ECOG performance status less than or equal to 1 (Karnofsky >70%).

   - Life expectancy > 3 months.

   - Patients must have normal organ and marrow function as defined below:

      - leukocytes greater than or equal to 3,000/mcL

      - absolute neutrophil count greater than or equal to 1,500/mcL

      - platelets greater than or equal to 100,000/mcL

      - total bilirubin less than or equal to 1.5 times ULN

      - AST(SGOT)/ALT(SGPT) less than or equal to 2.5 times institutional upper limit of
      normal creatinine within normal institutional limits

      - Subjects must have blood pressure (BP) no greater than 140 mmHg (systolic) and 90
      mmHg (diastolic) for eligibility. Initiation or adjustment of BP medication is
      permitted prior to study entry provided that the average of three BP readings at
      the time of enrollment is less than or equal to 140/90 mmHg

      - Patients must be able to swallow whole tablets. Tablets must not be crushed or
      chewed.

      - The effects of cabozantinib on the developing human fetus are unknown. For this
      reason and because receptor tyrosine kinases are known to be teratogenic, women
      of child-bearing potential and men must agree to use adequate contraception. All
      subjects of reproductive potential must agree to use both a barrier method and a
      second method of birth control during the course of the study and for 4 months
      after the last dose of study drug(s).

Sexually active subjects (men and women) must agree to use medically accepted barrier
methods of contraception (e.g., male or female condom) during the course of the study and
for 4 months after the last dose of study drug(s), even if oral contraceptives are also
used.

-Ability to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

   - Patients who have had anticancer therapy, including kinase inhibitors or any
   investigational agent within 4 weeks or 5 half-lives (whichever is shorter) (6 weeks
   for nitrosoureas or mitomycin C) prior to entering the study or those who have not
   recovered to baseline from adverse events (except alopecia and other non-clinically
   significant AEs). Patients who have received prior cabozantinib or inhibitors of c-MET
   or HGF are ineligible.

   - The subject has received radionuclide treatment within 6 weeks of the first dose of
   study treatment

   - The subject has received radiation therapy within 4 weeks (greater than or equal to 2
   weeks for palliative radiation therapy)

   - Patients with active brain metastases or carcinomatous meningitis or epidural disease
   are excluded from this clinical trial. Subjects with brain metastases previously
   treated with whole brain radiation or radiosurgery or subjects with epidural disease
   previously treated with radiation who are asymptomatic and have remained stable for 4
   weeks and do not require steroid treatment for at least 2 weeks before starting study
   treatment are eligible. Neurosurgical resection of brain metastases or brain biopsy is
   permitted if completed at least 3 months before starting study treatment. Baseline
   brain imaging with contrast-enhanced CT or MRI scans for subjects with known brain
   metastases is required to confirm eligibility.

   - Eligibility of subjects receiving any medications or substances known to affect or
   with the potential to affect the activity of cabozantinib will be determined following
   review of their cases by the Principal Investigator. Patients who are taking
   enzyme-inducing anticonvulsant agents are not eligible.

   - Patients with refractory nausea and vomiting, chronic gastrointestinal diseases (e.g.,
   inflammatory bowel disease), or significant bowel resection that could interfere with
   absorption.

   - Uncontrolled intercurrent illness including, but not limited to symptomatic congestive
   heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric
   illness/social situations that would limit compliance with study requirements.

   - Pregnant women are excluded from this study because cabozantinib has the potential for
   teratogenic or abortifacient effects. Because there is an unknown but potential risk
   for adverse events in nursing infants secondary to treatment of the mother with
   cabozantinib, breastfeeding should be discontinued if the mother is treated with
   cabozantinib.

   - Strong inhibitors and inducers of CYP3A4 can affect levels of cabozantinib and should
   be avoided whenever possible or switched to alternatives. Subjects requiring chronic
   concomitant treatment of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin,
   carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John s Wort)
   are not eligible for this study. Because the lists of these agents are constantly
   changing, it is important to regularly consult a frequently-updated list such as
   http://medicine.iupui.edu/clinpharm/ddis/; medical reference texts such as the
   Physicians Desk Reference may also provide this information. As part of the
   enrollment/informed consent procedures, the patient will be counseled on the risk of
   interactions with other agents, and what to do if new medications need to be
   prescribed or if the patient is considering a new overthe-counter medicine or herbal
   product.

   - HIV-positive patients on combination antiretroviral therapy are ineligible because of
   the potential for pharmacokinetic interactions with cabozantinib. Appropriate studies
   will be undertaken in patients receiving combination antiretroviral therapy when
   indicated.

   - The subject requires concomitant treatment, in therapeutic doses, with anticoagulants
   such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa
   inhibitors, or antiplatelet agents (e.g., clopidogrel). Low dose aspirin (less than or
   equal to 81 mg/day), low-dose warfarin (less than or equal to 1 mg/day), and
   prophylactic low molecular weight heparin (LMWH) are permitted. (Please note that
   there may be cases in which patients on study require anticoagulation for DVT/PE
   management; this does not necessitate taking

the patient off study.)

   - The subject has experienced any of the following

      - clinically-significant gastrointestinal bleeding within 6 months before the first
      dose of study treatment

      - hemoptysis of greater than or equal to 0.5 teaspoon (2.5 mL) of red blood within
      3 months before the first dose of study treatment

      - any other signs indicative of pulmonary hemorrhage within 3 months before the
      first dose of study treatment

   - The subject has radiographic evidence of cavitating pulmonary lesion(s).

   - The subject has tumor in contact with, invading, or encasing any major blood vessels

         systolic, or > 90 mm Hg diastolic despite optimal antihypertensive treatment
         within 7 days of the first dose of study treatment

         3. Any history of congenital long QT syndrome

         4. Any of the following within 6 months before the first dose of study
         treatment:

            - unstable angina pectoris

            - clinically-significant cardiac arrhythmias

            - stroke (including TIA, or other ischemic event)

            - myocardial infarction

            - thromboembolic event requiring therapeutic anticoagulation (Note:
            subjects with a venous filter (e.g. vena cava filter) are not eligible
            for this study)

      2. Gastrointestinal disorders particularly those associated with a high risk of
      perforation or fistula formation including:

         1. Any of the following within 28 days before the first dose of study treatment

            - intra-abdominal tumor/metastases invading GI mucosa

            - active peptic ulcer disease,

            - inflammatory bowel disease (including ulcerative colitis and Crohn s
            disease), diverticulitis, cholecystitis, symptomatic cholangitis or

            before the first dose of study treatment.

      3. Other disorders associated with a high risk of fistula formation including PEG
      tube placement within 3 months before the first dose of study therapy

      4. Other clinically significant disorders such as:

         1. serious non-healing wound/ulcer/bone fracture within 28 days before the
         first dose of study treatment

Cabozantinib for Adults With Advanced Soft Tissue Sarcoma

Background:

- Cabozantinib is a cancer treatment drug that blocks the growth of new blood vessels in tumors. It can also block a chemical on tumor cells that allows the cells to grow. A similar drug, pazopanib, is used to treat types of cancer known as sarcomas. Researchers want to see if cabozantinib can be an effective treatment for types of soft tissue sarcoma that have not responded to earlier treatments.

Objectives:

- To test the effectiveness of cabozantinib for soft tissue sarcomas that have not responded to standard treatments.

Eligibility:

- Individuals at least 18 years of age who have soft tissue sarcomas that have not responded to standard treatments.

Design:

- Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment.

- Participants will take cabozantinib tablets daily for 28-day cycles of treatment. The tablets should be taken whole on an empty stomach.

- Treatment will be monitored with frequent blood tests and imaging studies.

- Participants will continue to take cabozantinib for as long as the tumor does not become worse and the side effects are not too severe.

Stanford is currently accepting patients for this trial.

   - lipase <2.0 times ULN and no radiologic or clinical evidence of pancreatitis

   - urine protein/creatinine ratio (UPCR) less than or equal to 1

   - serum phosphorus calcium, magnesium and potassium greater than or equal to LLN

      - Subjects must have blood pressure (BP) no greater than 140 mmHg (systolic) and 90
      mmHg (diastolic) for eligibility. Initiation or adjustment of BP medication is
      permitted prior to study entry provided that the average of three BP readings at
      the time of enrollment is less than or equal to 140/90 mmHg

      - Patients must be able to swallow whole tablets. Tablets must not be crushed or
      chewed.

      - The effects of cabozantinib on the developing human fetus are unknown. For this
      reason and because receptor tyrosine kinases are known to be teratogenic, women
      of child-bearing potential and men must agree to use adequate contraception. All
      subjects of reproductive potential must agree to use both a barrier method and a
      second method of birth control during the course of the study and for 4 months
      after the last dose of study drug(s).

Sexually active subjects (men and women) must agree to use medically accepted barrier
methods of contraception (e.g., male or female condom) during the course of the study and
for 4 months after the last dose of study drug(s), even if oral contraceptives are also
used.

-Ability to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

   - Patients who have had anticancer therapy, including kinase inhibitors or any
   investigational agent within 4 weeks or 5 half-lives (whichever is shorter) (6 weeks
   for nitrosoureas or mitomycin C) prior to entering the study or those who have not
   recovered to baseline from adverse events (except alopecia and other non-clinically
   significant AEs). Patients who have received prior cabozantinib or inhibitors of c-MET
   or HGF are ineligible.

   - The subject has received radionuclide treatment within 6 weeks of the first dose of
   study treatment

   - The subject has received radiation therapy within 4 weeks (greater than or equal to 2
   weeks for palliative radiation therapy)

   - Patients with active brain metastases or carcinomatous meningitis or epidural disease
   are excluded from this clinical trial. Subjects with brain metastases previously
   treated with whole brain radiation or radiosurgery or subjects with epidural disease
   previously treated with radiation who are asymptomatic and have remained stable for 4
   weeks and do not require steroid treatment for at least 2 weeks before starting study
   treatment are eligible. Neurosurgical resection of brain metastases or brain biopsy is
   permitted if completed at least 3 months before starting study treatment. Baseline
   brain imaging with contrast-enhanced CT or MRI scans for subjects with known brain
   metastases is required to confirm eligibility.

   - Eligibility of subjects receiving any medications or substances known to affect or
   with the potential to affect the activity of cabozantinib will be determined following
   review of their cases by the Principal Investigator. Patients who are taking
   enzyme-inducing anticonvulsant agents are not eligible.

   - Patients with refractory nausea and vomiting, chronic gastrointestinal diseases (e.g.,
   inflammatory bowel disease), or significant bowel resection that could interfere with
   absorption.

   - Uncontrolled intercurrent illness including, but not limited to symptomatic congestive
   heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric
   illness/social situations that would limit compliance with study requirements.

   - Pregnant women are excluded from this study because cabozantinib has the potential for
   teratogenic or abortifacient effects. Because there is an unknown but potential risk
   for adverse events in nursing infants secondary to treatment of the mother with
   cabozantinib, breastfeeding should be discontinued if the mother is treated with
   cabozantinib.

   - Strong inhibitors and inducers of CYP3A4 can affect levels of cabozantinib and should
   be avoided whenever possible or switched to alternatives. Subjects requiring chronic
   concomitant treatment of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin,
   carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John s Wort)
   are not eligible for this study. Because the lists of these agents are constantly
   changing, it is important to regularly consult a frequently-updated list such as
   http://medicine.iupui.edu/clinpharm/ddis/; medical reference texts such as the
   Physicians Desk Reference may also provide this information. As part of the
   enrollment/informed consent procedures, the patient will be counseled on the risk of
   interactions with other agents, and what to do if new medications need to be
   prescribed or if the patient is considering a new overthe-counter medicine or herbal
   product.

   - HIV-positive patients on combination antiretroviral therapy are ineligible because of
   the potential for pharmacokinetic interactions with cabozantinib. Appropriate studies
   will be undertaken in patients receiving combination antiretroviral therapy when
   indicated.

   - The subject requires concomitant treatment, in therapeutic doses, with anticoagulants
   such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa
   inhibitors, or antiplatelet agents (e.g., clopidogrel). Low dose aspirin (less than or
   equal to 81 mg/day), low-dose warfarin (less than or equal to 1 mg/day), and
   prophylactic low molecular weight heparin (LMWH) are permitted. (Please note that
   there may be cases in which patients on study require anticoagulation for DVT/PE
   management; this does not necessitate taking

the patient off study.)

   - The subject has experienced any of the following

      - clinically-significant gastrointestinal bleeding within 6 months before the first
      dose of study treatment

      - hemoptysis of greater than or equal to 0.5 teaspoon (2.5 mL) of red blood within
      3 months before the first dose of study treatment

      - any other signs indicative of pulmonary hemorrhage within 3 months before the
      first dose of study treatment

   - The subject has radiographic evidence of cavitating pulmonary lesion(s).

   - The subject has tumor in contact with, invading, or encasing any major blood vessels

   - The subject has evidence of tumor invading the GI tract (esophagus, stomach, small or
   large bowel, rectum or anus), or any evidence of endotracheal or endobronchial tumor
   within 28 days before the first dose of cabozantinib

         (moderate) or Class IV (severe) at the time of screening

         2. Concurrent uncontrolled hypertension defined as sustained BP > 140 mm Hg
         systolic, or > 90 mm Hg diastolic despite optimal antihypertensive treatment
         within 7 days of the first dose of study treatment

         3. Any history of congenital long QT syndrome

         4. Any of the following within 6 months before the first dose of study
         treatment:

            - unstable angina pectoris

            - clinically-significant cardiac arrhythmias

            - stroke (including TIA, or other ischemic event)

            - myocardial infarction

            - thromboembolic event requiring therapeutic anticoagulation (Note:
            subjects with a venous filter (e.g. vena cava filter) are not eligible
            for this study)

      2. Gastrointestinal disorders particularly those associated with a high risk of
      perforation or fistula formation including:

         1. Any of the following within 28 days before the first dose of study treatment

            - intra-abdominal tumor/metastases invading GI mucosa

            - active peptic ulcer disease,

            - inflammatory bowel disease (including ulcerative colitis and Crohn s
            disease), diverticulitis, cholecystitis, symptomatic cholangitis or
            appendicitis

            - malabsorption syndrome

         2. Any of the following within 6 months before the first dose of study
         treatment:

            - abdominal fistula

            - gastrointestinal perforation

            - bowel obstruction or gastric outlet obstruction

            intra-abdominal abscess must be confirmed prior to initiating treatment
            with cabozantinib even if the abscess occurred more that 6 months
            before the first dose of study treatment.

      3. Other disorders associated with a high risk of fistula formation including PEG
      tube placement within 3 months before the first dose of study therapy

      4. Other clinically significant disorders such as:

         1. serious non-healing wound/ulcer/bone fracture within 28 days before the
         first dose of study treatment

         2. history of organ transplant, including allogeneic bone marrow transplant

         3. concurrent uncompensated hypothyroidism or thyroid dysfunction within 7 days
         before the first dose of study treatment

   >500 ms within 28 days before enrollment. Note: if initial QTcF is found to be > 500
   ms, two additional EKGs separated by at least 3 minutes should be performed. If the
   average of these three consecutive results for QTcF is less than or equal to 500 ms,
   the subject meets eligibility in this regard.

   - The subject is unable or unwilling to abide by the study protocol or cooperate fully
   with the investigator or designee.

Cabozantinib for Adults With Advanced Soft Tissue Sarcoma

Background:

- Cabozantinib is a cancer treatment drug that blocks the growth of new blood vessels in tumors. It can also block a chemical on tumor cells that allows the cells to grow. A similar drug, pazopanib, is used to treat types of cancer known as sarcomas. Researchers want to see if cabozantinib can be an effective treatment for types of soft tissue sarcoma that have not responded to earlier treatments.

Objectives:

- To test the effectiveness of cabozantinib for soft tissue sarcomas that have not responded to standard treatments.

Eligibility:

- Individuals at least 18 years of age who have soft tissue sarcomas that have not responded to standard treatments.

Design:

- Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment.

- Participants will take cabozantinib tablets daily for 28-day cycles of treatment. The tablets should be taken whole on an empty stomach.

- Treatment will be monitored with frequent blood tests and imaging studies.

- Participants will continue to take cabozantinib for as long as the tumor does not become worse and the side effects are not too severe.

Stanford is currently accepting patients for this trial.

   investigational agent within 4 weeks or 5 half-lives (whichever is shorter) (6 weeks
   for nitrosoureas or mitomycin C) prior to entering the study or those who have not
   recovered to baseline from adverse events (except alopecia and other non-clinically
   significant AEs). Patients who have received prior cabozantinib or inhibitors of c-MET
   or HGF are ineligible.

   - The subject has received radionuclide treatment within 6 weeks of the first dose of
   study treatment

   - The subject has received radiation therapy within 4 weeks (greater than or equal to 2
   weeks for palliative radiation therapy)

   - Patients with active brain metastases or carcinomatous meningitis or epidural disease
   are excluded from this clinical trial. Subjects with brain metastases previously
   treated with whole brain radiation or radiosurgery or subjects with epidural disease
   previously treated with radiation who are asymptomatic and have remained stable for 4
   weeks and do not require steroid treatment for at least 2 weeks before starting study
   treatment are eligible. Neurosurgical resection of brain metastases or brain biopsy is
   permitted if completed at least 3 months before starting study treatment. Baseline
   brain imaging with contrast-enhanced CT or MRI scans for subjects with known brain
   metastases is required to confirm eligibility.

   - Eligibility of subjects receiving any medications or substances known to affect or
   with the potential to affect the activity of cabozantinib will be determined following
   review of their cases by the Principal Investigator. Patients who are taking
   enzyme-inducing anticonvulsant agents are not eligible.

   - Patients with refractory nausea and vomiting, chronic gastrointestinal diseases (e.g.,
   inflammatory bowel disease), or significant bowel resection that could interfere with
   absorption.

   - Uncontrolled intercurrent illness including, but not limited to symptomatic congestive
   heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric
   illness/social situations that would limit compliance with study requirements.

   - Pregnant women are excluded from this study because cabozantinib has the potential for
   teratogenic or abortifacient effects. Because there is an unknown but potential risk
   for adverse events in nursing infants secondary to treatment of the mother with
   cabozantinib, breastfeeding should be discontinued if the mother is treated with
   cabozantinib.

   - Strong inhibitors and inducers of CYP3A4 can affect levels of cabozantinib and should
   be avoided whenever possible or switched to alternatives. Subjects requiring chronic
   concomitant treatment of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin,
   carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John s Wort)
   are not eligible for this study. Because the lists of these agents are constantly
   changing, it is important to regularly consult a frequently-updated list such as
   http://medicine.iupui.edu/clinpharm/ddis/; medical reference texts such as the
   Physicians Desk Reference may also provide this information. As part of the
   enrollment/informed consent procedures, the patient will be counseled on the risk of
   interactions with other agents, and what to do if new medications need to be
   prescribed or if the patient is considering a new overthe-counter medicine or herbal
   product.

   - HIV-positive patients on combination antiretroviral therapy are ineligible because of
   the potential for pharmacokinetic interactions with cabozantinib. Appropriate studies
   will be undertaken in patients receiving combination antiretroviral therapy when
   indicated.

   - The subject requires concomitant treatment, in therapeutic doses, with anticoagulants
   such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa
   inhibitors, or antiplatelet agents (e.g., clopidogrel). Low dose aspirin (less than or
   equal to 81 mg/day), low-dose warfarin (less than or equal to 1 mg/day), and
   prophylactic low molecular weight heparin (LMWH) are permitted. (Please note that
   there may be cases in which patients on study require anticoagulation for DVT/PE
   management; this does not necessitate taking

the patient off study.)

   - The subject has experienced any of the following

      - clinically-significant gastrointestinal bleeding within 6 months before the first
      dose of study treatment

      - hemoptysis of greater than or equal to 0.5 teaspoon (2.5 mL) of red blood within
      3 months before the first dose of study treatment

      - any other signs indicative of pulmonary hemorrhage within 3 months before the
      first dose of study treatment

   - The subject has radiographic evidence of cavitating pulmonary lesion(s).

   - The subject has tumor in contact with, invading, or encasing any major blood vessels

   - The subject has evidence of tumor invading the GI tract (esophagus, stomach, small or
   large bowel, rectum or anus), or any evidence of endotracheal or endobronchial tumor
   within 28 days before the first dose of cabozantinib

         systolic, or > 90 mm Hg diastolic despite optimal antihypertensive treatment
         within 7 days of the first dose of study treatment

         3. Any history of congenital long QT syndrome

         4. Any of the following within 6 months before the first dose of study
         treatment:

            - unstable angina pectoris

            - clinically-significant cardiac arrhythmias

            - stroke (including TIA, or other ischemic event)

            - myocardial infarction

            - thromboembolic event requiring therapeutic anticoagulation (Note:
            subjects with a venous filter (e.g. vena cava filter) are not eligible
            for this study)

      2. Gastrointestinal disorders particularly those associated with a high risk of
      perforation or fistula formation including:

         1. Any of the following within 28 days before the first dose of study treatment

            - intra-abdominal tumor/metastases invading GI mucosa

            - active peptic ulcer disease,

            - inflammatory bowel disease (including ulcerative colitis and Crohn s
            disease), diverticulitis, cholecystitis, symptomatic cholangitis or

            before the first dose of study treatment.

      3. Other disorders associated with a high risk of fistula formation including PEG
      tube placement within 3 months before the first dose of study therapy

      4. Other clinically significant disorders such as:

         1. serious non-healing wound/ulcer/bone fracture within 28 days before the
         first dose of study treatment

Cabozantinib for Adults With Advanced Soft Tissue Sarcoma

Background:

- Cabozantinib is a cancer treatment drug that blocks the growth of new blood vessels in tumors. It can also block a chemical on tumor cells that allows the cells to grow. A similar drug, pazopanib, is used to treat types of cancer known as sarcomas. Researchers want to see if cabozantinib can be an effective treatment for types of soft tissue sarcoma that have not responded to earlier treatments.

Objectives:

- To test the effectiveness of cabozantinib for soft tissue sarcomas that have not responded to standard treatments.

Eligibility:

- Individuals at least 18 years of age who have soft tissue sarcomas that have not responded to standard treatments.

Design:

- Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment.

- Participants will take cabozantinib tablets daily for 28-day cycles of treatment. The tablets should be taken whole on an empty stomach.

- Treatment will be monitored with frequent blood tests and imaging studies.

- Participants will continue to take cabozantinib for as long as the tumor does not become worse and the side effects are not too severe.

Stanford is currently accepting patients for this trial.

Phase 2

Eligibility


- INCLUSION CRITERIA:

   - Patients must have histologically or cytologically confirmed soft tissue sarcoma that
   is metastatic or unresectable and for which standard treatment that prolongs survival
   does not exist or is no longer effective.

   - Patients must have measurable disease, defined as at least one lesion that can be
   accurately measured in at least one dimension (longest diameter to be recorded for
   non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional
   techniques or as >10 mm with spiral CT scan, MRI, or calipers by clinical exam.

   - Patients are allowed prior VEGFR-TKI therapy. Patients will be stratified based on
   prior VEGFR-TKI therapy.

   - Age greater than or equal to 18 years. Because no dosing or adverse event data are
   currently available on the use of cabozantinib in patients <18 years of age, children
   are excluded from this study.

   - ECOG performance status less than or equal to 1 (Karnofsky >70%).

   - Life expectancy > 3 months.

   - Patients must have normal organ and marrow function as defined below:

      - leukocytes greater than or equal to 3,000/mcL

      - absolute neutrophil count greater than or equal to 1,500/mcL

      - platelets greater than or equal to 100,000/mcL

      - total bilirubin less than or equal to 1.5 times ULN

      - AST(SGOT)/ALT(SGPT) less than or equal to 2.5 times institutional upper limit of

      permitted prior to study entry provided that the average of three BP readings at
      the time of enrollment is less than or equal to 140/90 mmHg

      - Patients must be able to swallow whole tablets. Tablets must not be crushed or
      chewed.

      - The effects of cabozantinib on the developing human fetus are unknown. For this
      reason and because receptor tyrosine kinases are known to be teratogenic, women
      of child-bearing potential and men must agree to use adequate contraception. All
      subjects of reproductive potential must agree to use both a barrier method and a
      second method of birth control during the course of the study and for 4 months
      after the last dose of study drug(s).

Sexually active subjects (men and women) must agree to use medically accepted barrier
methods of contraception (e.g., male or female condom) during the course of the study and

   inflammatory bowel disease), or significant bowel resection that could interfere with
   absorption.

   - Uncontrolled intercurrent illness including, but not limited to symptomatic congestive
   heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric
   illness/social situations that would limit compliance with study requirements.

   - Pregnant women are excluded from this study because cabozantinib has the potential for
   teratogenic or abortifacient effects. Because there is an unknown but potential risk
   for adverse events in nursing infants secondary to treatment of the mother with
   cabozantinib, breastfeeding should be discontinued if the mother is treated with
   cabozantinib.

   - Strong inhibitors and inducers of CYP3A4 can affect levels of cabozantinib and should
   be avoided whenever possible or switched to alternatives. Subjects requiring chronic
   concomitant treatment of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin,
   carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John s Wort)
   are not eligible for this study. Because the lists of these agents are constantly
   changing, it is important to regularly consult a frequently-updated list such as
   http://medicine.iupui.edu/clinpharm/ddis/; medical reference texts such as the
   Physicians Desk Reference may also provide this information. As part of the
   enrollment/informed consent procedures, the patient will be counseled on the risk of
   interactions with other agents, and what to do if new medications need to be
   prescribed or if the patient is considering a new overthe-counter medicine or herbal
   product.

   - HIV-positive patients on combination antiretroviral therapy are ineligible because of
   the potential for pharmacokinetic interactions with cabozantinib. Appropriate studies
   will be undertaken in patients receiving combination antiretroviral therapy when
   indicated.

   - The subject requires concomitant treatment, in therapeutic doses, with anticoagulants
   such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa
   inhibitors, or antiplatelet agents (e.g., clopidogrel). Low dose aspirin (less than or
   equal to 81 mg/day), low-dose warfarin (less than or equal to 1 mg/day), and
   prophylactic low molecular weight heparin (LMWH) are permitted. (Please note that
   there may be cases in which patients on study require anticoagulation for DVT/PE
   management; this does not necessitate taking

the patient off study.)

   - The subject has experienced any of the following

      - clinically-significant gastrointestinal bleeding within 6 months before the first
      dose of study treatment

      - hemoptysis of greater than or equal to 0.5 teaspoon (2.5 mL) of red blood within
      3 months before the first dose of study treatment

      - any other signs indicative of pulmonary hemorrhage within 3 months before the

         systolic, or > 90 mm Hg diastolic despite optimal antihypertensive treatment
         within 7 days of the first dose of study treatment

         3. Any history of congenital long QT syndrome

         4. Any of the following within 6 months before the first dose of study
         treatment:

            - unstable angina pectoris

            - clinically-significant cardiac arrhythmias

            - stroke (including TIA, or other ischemic event)

            - myocardial infarction

            - thromboembolic event requiring therapeutic anticoagulation (Note:
            subjects with a venous filter (e.g. vena cava filter) are not eligible
            for this study)

      2. Gastrointestinal disorders particularly those associated with a high risk of
      perforation or fistula formation including:

         1. Any of the following within 28 days before the first dose of study treatment

            - intra-abdominal tumor/metastases invading GI mucosa

            - active peptic ulcer disease,

Cabozantinib for Adults With Advanced Soft Tissue Sarcoma

Background:

- Cabozantinib is a cancer treatment drug that blocks the growth of new blood vessels in tumors. It can also block a chemical on tumor cells that allows the cells to grow. A similar drug, pazopanib, is used to treat types of cancer known as sarcomas. Researchers want to see if cabozantinib can be an effective treatment for types of soft tissue sarcoma that have not responded to earlier treatments.

Objectives:

- To test the effectiveness of cabozantinib for soft tissue sarcomas that have not responded to standard treatments.

Eligibility:

- Individuals at least 18 years of age who have soft tissue sarcomas that have not responded to standard treatments.

Design:

- Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment.

- Participants will take cabozantinib tablets daily for 28-day cycles of treatment. The tablets should be taken whole on an empty stomach.

- Treatment will be monitored with frequent blood tests and imaging studies.

- Participants will continue to take cabozantinib for as long as the tumor does not become worse and the side effects are not too severe.

Stanford is currently accepting patients for this trial.

Phase 2

Eligibility


- INCLUSION CRITERIA:

   - Patients must have histologically or cytologically confirmed soft tissue sarcoma that
   is metastatic or unresectable and for which standard treatment that prolongs survival
   does not exist or is no longer effective.

   - Patients must have measurable disease, defined as at least one lesion that can be
   accurately measured in at least one dimension (longest diameter to be recorded for
   non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional
   techniques or as >10 mm with spiral CT scan, MRI, or calipers by clinical exam.

   - Patients are allowed prior VEGFR-TKI therapy. Patients will be stratified based on
   prior VEGFR-TKI therapy.

   - Age greater than or equal to 18 years. Because no dosing or adverse event data are
   currently available on the use of cabozantinib in patients <18 years of age, children
   are excluded from this study.

   - ECOG performance status less than or equal to 1 (Karnofsky >70%).

   - Life expectancy > 3 months.

   - Patients must have normal organ and marrow function as defined below:

      - leukocytes greater than or equal to 3,000/mcL

      - absolute neutrophil count greater than or equal to 1,500/mcL

      - platelets greater than or equal to 100,000/mcL

      - total bilirubin less than or equal to 1.5 times ULN

      - AST(SGOT)/ALT(SGPT) less than or equal to 2.5 times institutional upper limit of
      normal creatinine within normal institutional limits

      - Subjects must have blood pressure (BP) no greater than 140 mmHg (systolic) and 90
      mmHg (diastolic) for eligibility. Initiation or adjustment of BP medication is
      permitted prior to study entry provided that the average of three BP readings at
      the time of enrollment is less than or equal to 140/90 mmHg

      - Patients must be able to swallow whole tablets. Tablets must not be crushed or
      chewed.

      - The effects of cabozantinib on the developing human fetus are unknown. For this
      reason and because receptor tyrosine kinases are known to be teratogenic, women
      of child-bearing potential and men must agree to use adequate contraception. All
      subjects of reproductive potential must agree to use both a barrier method and a
      second method of birth control during the course of the study and for 4 months
      after the last dose of study drug(s).

Sexually active subjects (men and women) must agree to use medically accepted barrier
methods of contraception (e.g., male or female condom) during the course of the study and
for 4 months after the last dose of study drug(s), even if oral contraceptives are also
used.

Cabozantinib for Adults With Advanced Soft Tissue Sarcoma

Background:

- Cabozantinib is a cancer treatment drug that blocks the growth of new blood vessels in tumors. It can also block a chemical on tumor cells that allows the cells to grow. A similar drug, pazopanib, is used to treat types of cancer known as sarcomas. Researchers want to see if cabozantinib can be an effective treatment for types of soft tissue sarcoma that have not responded to earlier treatments.

Objectives:

- To test the effectiveness of cabozantinib for soft tissue sarcomas that have not responded to standard treatments.

Eligibility:

- Individuals at least 18 years of age who have soft tissue sarcomas that have not responded to standard treatments.

Design:

- Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment.

- Participants will take cabozantinib tablets daily for 28-day cycles of treatment. The tablets should be taken whole on an empty stomach.

- Treatment will be monitored with frequent blood tests and imaging studies.

- Participants will continue to take cabozantinib for as long as the tumor does not become worse and the side effects are not too severe.

Stanford is currently accepting patients for this trial.

Eligibility


- INCLUSION CRITERIA:

   - Patients must have histologically or cytologically confirmed soft tissue sarcoma that
   is metastatic or unresectable and for which standard treatment that prolongs survival
   does not exist or is no longer effective.

   - Patients must have measurable disease, defined as at least one lesion that can be
   accurately measured in at least one dimension (longest diameter to be recorded for
   non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional
   techniques or as >10 mm with spiral CT scan, MRI, or calipers by clinical exam.

   - Patients are allowed prior VEGFR-TKI therapy. Patients will be stratified based on
   prior VEGFR-TKI therapy.

   - Age greater than or equal to 18 years. Because no dosing or adverse event data are
   currently available on the use of cabozantinib in patients <18 years of age, children
   are excluded from this study.

   - ECOG performance status less than or equal to 1 (Karnofsky >70%).

   - Life expectancy > 3 months.

   - Patients must have normal organ and marrow function as defined below:

      - leukocytes greater than or equal to 3,000/mcL

      - absolute neutrophil count greater than or equal to 1,500/mcL

      - platelets greater than or equal to 100,000/mcL

      - total bilirubin less than or equal to 1.5 times ULN

      - AST(SGOT)/ALT(SGPT) less than or equal to 2.5 times institutional upper limit of
      normal creatinine within normal institutional limits

OR

   - creatinine clearance greater than or equal to 60 mL/min/1.73 m(2) for patients with
   creatinine levels above institutional normal.

   - hemoglobin greater than or equal to 9 g/dL

   - serum albumin greater than or equal to 2.8g/dL

   - lipase <2.0 times ULN and no radiologic or clinical evidence of pancreatitis

   - urine protein/creatinine ratio (UPCR) less than or equal to 1

   - serum phosphorus calcium, magnesium and potassium greater than or equal to LLN

      - Subjects must have blood pressure (BP) no greater than 140 mmHg (systolic) and 90
      mmHg (diastolic) for eligibility. Initiation or adjustment of BP medication is
      permitted prior to study entry provided that the average of three BP readings at
      the time of enrollment is less than or equal to 140/90 mmHg

      - Patients must be able to swallow whole tablets. Tablets must not be crushed or
      chewed.

      - The effects of cabozantinib on the developing human fetus are unknown. For this
      reason and because receptor tyrosine kinases are known to be teratogenic, women
      of child-bearing potential and men must agree to use adequate contraception. All
      subjects of reproductive potential must agree to use both a barrier method and a
      second method of birth control during the course of the study and for 4 months
      after the last dose of study drug(s).

Sexually active subjects (men and women) must agree to use medically accepted barrier
methods of contraception (e.g., male or female condom) during the course of the study and
for 4 months after the last dose of study drug(s), even if oral contraceptives are also
used.

-Ability to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

   - Patients who have had anticancer therapy, including kinase inhibitors or any
   investigational agent within 4 weeks or 5 half-lives (whichever is shorter) (6 weeks
   for nitrosoureas or mitomycin C) prior to entering the study or those who have not
   recovered to baseline from adverse events (except alopecia and other non-clinically
   significant AEs). Patients who have received prior cabozantinib or inhibitors of c-MET
   or HGF are ineligible.

   - The subject has received radionuclide treatment within 6 weeks of the first dose of
   study treatment

   - The subject has received radiation therapy within 4 weeks (greater than or equal to 2
   weeks for palliative radiation therapy)

   - Patients with active brain metastases or carcinomatous meningitis or epidural disease
   are excluded from this clinical trial. Subjects with brain metastases previously
   treated with whole brain radiation or radiosurgery or subjects with epidural disease
   previously treated with radiation who are asymptomatic and have remained stable for 4
   weeks and do not require steroid treatment for at least 2 weeks before starting study
   treatment are eligible. Neurosurgical resection of brain metastases or brain biopsy is
   permitted if completed at least 3 months before starting study treatment. Baseline
   brain imaging with contrast-enhanced CT or MRI scans for subjects with known brain
   metastases is required to confirm eligibility.

   - Eligibility of subjects receiving any medications or substances known to affect or
   with the potential to affect the activity of cabozantinib will be determined following
   review of their cases by the Principal Investigator. Patients who are taking
   enzyme-inducing anticonvulsant agents are not eligible.

   - Patients with refractory nausea and vomiting, chronic gastrointestinal diseases (e.g.,
   inflammatory bowel disease), or significant bowel resection that could interfere with
   absorption.

   - Uncontrolled intercurrent illness including, but not limited to symptomatic congestive
   heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric
   illness/social situations that would limit compliance with study requirements.

   - Pregnant women are excluded from this study because cabozantinib has the potential for
   teratogenic or abortifacient effects. Because there is an unknown but potential risk
   for adverse events in nursing infants secondary to treatment of the mother with
   cabozantinib, breastfeeding should be discontinued if the mother is treated with
   cabozantinib.

   - Strong inhibitors and inducers of CYP3A4 can affect levels of cabozantinib and should
   be avoided whenever possible or switched to alternatives. Subjects requiring chronic
   concomitant treatment of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin,
   carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John s Wort)
   are not eligible for this study. Because the lists of these agents are constantly
   changing, it is important to regularly consult a frequently-updated list such as
   http://medicine.iupui.edu/clinpharm/ddis/; medical reference texts such as the
   Physicians Desk Reference may also provide this information. As part of the
   enrollment/informed consent procedures, the patient will be counseled on the risk of
   interactions with other agents, and what to do if new medications need to be
   prescribed or if the patient is considering a new overthe-counter medicine or herbal
   product.

   - HIV-positive patients on combination antiretroviral therapy are ineligible because of
   the potential for pharmacokinetic interactions with cabozantinib. Appropriate studies
   will be undertaken in patients receiving combination antiretroviral therapy when
   indicated.

   - The subject requires concomitant treatment, in therapeutic doses, with anticoagulants
   such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa
   inhibitors, or antiplatelet agents (e.g., clopidogrel). Low dose aspirin (less than or
   equal to 81 mg/day), low-dose warfarin (less than or equal to 1 mg/day), and
   prophylactic low molecular weight heparin (LMWH) are permitted. (Please note that
   there may be cases in which patients on study require anticoagulation for DVT/PE
   management; this does not necessitate taking

the patient off study.)
