Eligibility Criteria Expand/Collapse

Eligibility Criteria for Step 1 (Please refer to the Protocol for the Eligibility Criteria for Step 2)

a. Disease Related Criteria

1. Participants must have histologically confirmed melanoma that is Stage III or IV, unresectable, recurrent, or metastatic non-uveal melanoma according to criteria in Section 4.1.


Participants must have histologically confirmed squamous cell carcinoma of the head and neck (HNSCC) that is either locally recurrent and non-amendable to curative therapy (e.g., radiation, surgery) or metastatic. The primary tumor location must be the oropharynx, oral cavity, hypopharynx, or larynx. Primary tumor site of nasopharynx (any histology) or unknown primary tumor are not eligible.

Note: For participants with primary oropharyngeal cancer, HPV or p16 status must be known prior to Step 1 registration.

2. Participants must have disease presentation consistent with measurable disease. Note: Current disease measurements will not be required until Step 2 registration.

3. Participants must have had documented progression within 12 weeks after the last dose of PD-1 checkpoint inhibition-based therapy. Participants must have been receiving checkpoint inhibition for a minimum of 6 weeks. Participants who recur during adjuvant anti-PD1 treatment or within 12 weeks of completion of adjuvant anti-PD1 treatment are eligible if they have measurable disease and are considered unresectable.

4. Participants with known human immunodeficiency virus (HIV)-infection must be receiving anti-retroviral therapy and have an undetectable viral load test within 6 months prior to Step 1 registration.

5. Participants with evidence of chronic hepatitis B virus (HBV) infection must have undetectable HBV viral load within 28 days prior to Step 1 registration.

6. Participants with a history of hepatitis C virus (HCV) infection must have no detectable viral load within 28 days prior to Step 1 registration.

7. Participants must not have an active infection requiring systemic therapy (except HBV, HCV or HIV as mentioned above).

8. Participants must not have known history of congenital long QT syndrome and must not have experienced unstable angina pectoris, clinically significant cardiac arrhythmias, or stroke (TIA or other ischemic event) within 90 days prior to Step 1 registration.

9. Participants must not have experienced myocardial infarction or thromboembolic event requiring anticoagulation within 90 days prior to Step 1 registration, unless clinically stable with ongoing medical management.

b. Prior/Concurrent Therapy Criteria

1. Participants must have recovered to baseline or ≤ Grade 1 CTCAE v5 toxicities related to any prior treatments, unless adverse events are deemed clinically nonsignificant by the treating investigator or stable on supportive therapy.

2. Participants must not have received more than one prior primary radiotherapy regimen, curative or adjuvant, to the mucosal surfaces of the head and neck, with the additional following criteria.

i. If the primary radiation is combined with chemotherapy, a minimum of 16 weeks will be required to have elapsed between the end of radiotherapy and Step 1 registration. If the radiation is given alone, a minimum of 8 weeks will be required to have elapsed between the end of radiotherapy and Step 1 registration.

ii. Additional palliative radiotherapy regimens are permitted but cannot have been administered to previously treated tissue (i.e., overlapping fields are excluded) with the exception of CNS radiation and must be completed at least 4 weeks prior to Step 1 registration.

iii. Treatment areas should be healed with no sequelae from RT that would predispose to fistula formation.

3. Participants must not have received prior treatment with anti-VEGF therapies for any reason.

c. Clinical/Laboratory Criteria

1. Participants must be ≥ 18 years of age.

2. Participants must have a Zubrod Performance Status 0 or 1. See Section 10.4.

3. Participants must have adequate cardiac function. Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, must have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification (see Appendix 18.3), and must be class 2B or better to be eligible for this trial.

4. Participants must not have any known significant organ disfunction that, in the opinion of the treating investigator, may impact suitability for receiving combination nivolumab/cabozantinib treatment.

5. Participants must be able to take oral medication without breaking, opening, crushing, dissolving or chewing capsules.

6. Participants must not have malabsorption syndrome.

7. Participants must not have active autoimmune disease requiring systemic steroids (equivalent of > 10 mg of prednisone) or other immune suppression. Exceptions:

- Type 1 diabetes mellitus.
- Endocrinopathy only requiring hormone replacement.
- Skin disorders (e.g., vitiligo, psoriasis, or alopecia) not requiring systemic treatment.
- Conditions not expected to recur in the absence of an external trigger.

8. Participants must not have received an organ allograft.

9. Participants must not have a history of hemoptysis (defined as ≥ 1/2 tsp of bright red blood per day) or tumor bleeding within 90 days prior to Step 1 registration.

10. Participants must not have any of the following criteria due to the possibility of increased risk for tumor bleeding with cabozantinib therapy:

- Prior carotid bleeding.
- Tumors that invade major vessels (e.g., the carotid) as shown unequivocally by imaging studies.
- Central (e.g., within 2 cm from the hilum) lung metastases that are cavitary as shown unequivocally by imaging studies.
- Any prior history of bleeding related to the current head and neck cancer.
- History of gross hemoptysis (bright red blood of 1/2 teaspoon or more per episode of coughing) within 3 months.

11. Participants must not require concomitant anticoagulation with coumarin agents (e.g., warfarin), direct thrombin inhibitors (e.g., dabigatran), direct factor Xa inhibitor betrixaban, or platelet inhibitors (e.g., clopidogrel). Participants must not require anticoagulants except for the following:

- Prophylactic use of low-dose aspirin for cardio-protection (per local applicable guidelines) and low-dose low molecular weight heparins (LMWH).

- Therapeutic doses of LMWH or anticoagulation with direct factor Xa inhibitors, rivaroxaban, edoxaban, or apixaban in participants without known brain metastases who are on a stable dose of the anticoagulant for at least 1 week prior to Step 1 registration without clinically significant hemorrhagic complications from the anticoagulation regimen or the tumor.

12. Participants must not have evidence of preexisting uncontrolled hypertension 28 days prior to Step 1 registration as documented by baseline blood pressure reading with systolic blood pressure >150 mmHg and/or diastolic blood pressure >90 mmHg. Participants on antihypertensive therapies with controlled blood pressure are eligible.

13. Participants must not have a prior or concurrent malignancy whose natural history or treatment (in the opinion of the treating physician) has the potential to interfere with the safety or efficacy assessment of the investigational regimen.

14. Participants must not be pregnant or nursing due to the known safety profiles of the drugs in this study. Individuals who are of reproductive potential must have agreed to use an effective contraceptive method with details provided as a part of the consent process. A person who has had menses at any time in the preceding 12 consecutive months or who has semen likely to contain sperm is considered to be of "reproductive potential”. In addition to routine contraceptive methods, "effective contraception" also includes refraining from sexual activity that might result in pregnancy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) including hysterectomy, bilateral oophorectomy, bilateral tubal ligation/occlusion and vasectomy with testing showing no sperm in the semen.

d. Specimen and Data Submission Criteria

1. Participants must:

Have an adequate archival tissue specimen verified by the local pathologist and documented on the Pathology Review Form (see Section 15.3) from a procedure obtained after the development of resistance to anti-PD-1/L1 therapy. Archival tissue must consist of tumor block or at least 1 H&E-stained 4-5 micron slide and 20 freshly cut serially sectioned and numbered 4-5 micron unstained, uncharged slides (see Section 15.3).


Be willing to undergo research biopsy AND have tumor accessible for biopsy based on the following criteria:

- Mediastinal, laparoscopic, gastrointestinal, or bronchial endoscopic biopsies can be obtained incidentally to a clinically necessary procedure and NOT for the sole purpose of the clinical trial.
- Acceptable biopsy procedures are:
- Percutaneous biopsy with local anesthetic and/or sedation with an expected risk of severe complications < 2%.
- Direct transoral biopsy (with or without local anesthetic and/or sedation) with an expected risk of severe complications < 2%.
- Excisional cutaneous biopsy with local anesthetic and/or sedation with an expected risk of severe complications < 2%.
- Biopsy with removal of additional tumor tissue during a medically necessary mediastinoscopy, laparoscopy, gastrointestinal endoscopy, bronchoscopy or craniotomy. No open surgical, laparoscopic or endoscopic procedure should be performed solely to obtain a biopsy for this protocol.
- Removal of additional tumor tissue during a medically necessary surgical procedure.

2. Participants must submit whole blood for germline genomic analysis (See Section 15.1 and Section 15.3.a.2).

3. Participants must have been offered the opportunity to participate in specimen banking as outlined in Section 15.4.
