About this trial
This phase II trial studies the good and bad effects of the combination of drugs called cabozantinib and nivolumab in treating patients with melanoma or squamous cell head and neck cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial may help doctors determine how quickly patients can be divided into groups based on biomarkers in their tumors. A biomarker is a biological molecule found in the blood, other body fluids, or in tissues that is a sign of a normal or abnormal process or a sign of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. The two biomarkers that this trial is studying are "tumor mutational burden" and "tumor inflammation signature." Another purpose of this trial is to help doctors learn if cabozantinib and nivolumab shrink or stabilize the cancer, and whether patients respond differently to the combination depending on the status of the biomarkers.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
STEP 1 - SPECIMEN SUBMISSION
Participants must have histologically confirmed melanoma that is stage III or IV, unresectable, recurrent, or metastatic non-uveal melanoma OR 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, human papillomavirus (HPV) or p16 status must be known prior to step 1 registration
Participants must have disease presentation consistent with measurable disease. Note: Current disease measurements will not be required until step 2 registration

Trial outcomes
Primary outcomes
Biomarker results turnaround time
A biomarker turnaround time estimate of at least 75% less than or equal to 21 days will be considered successful with respect to feasibility. For melanoma participants prior to Revision #7, turnaround time is defined as the time-period between date of tissue submission by the site to central repository and date the site was sent notification of participant molecular group determination. For head and neck squamous cell carcinoma (HNSCC) and melanoma participants after Revision #7, turnaround time is defined as the time-period between date of tissue submission by the site to central repository and one day after results have been received from the initial tissue submission by the Southwest Oncology Group Statistics and Data Management Center to simulate when the site would have received notification of participant molecular group determination.
Objective response rate
Confirmed and unconfirmed complete and partial responses in tumor inflammation score subgroups. Will assess biomarker response association. To test this association, will consider combination of biomarkers coded as 0 = Lo/Lo, 1 = Lo/Hi or Hi/Lo, and 2 = Hi/Hi. Assume each biomarker level is associated with an odds-ratio of approximately 3.1 (for example, corresponding to a difference in response rate of 5 percent to 14 percent from Lo/Lo to Lo/Hi or Hi/Lo). For the melanoma cohort, with approximately equal sized biomarker combination subgroups, a one-sided 0.10 level test for trend using (0,1,2) coding with logistic regression has a power of 80%. The same analysis for HNSCC will have lower power for the same effect size due to the unequal frequencies in the subgroups defined by the biomarkers. We will also conduct disease-by-biomarker interaction tests; however, there will be limited power to detect even to detect relatively large interaction parameters.
Secondary outcomes
Rate and profile of >= grade 3 treatment-related adverse events
Per Common Terminology Criteria for Adverse Events 5.0. With respect to overall disease group, 60 participants are sufficient to estimate the probability of a particular toxicity to within +/- 13 percent. Any toxicity occurring with at least a 5 percent probability is likely to be seen at least once (95 percent chance).
Disease control rate
Will be estimated using the method of Kaplan-Meier.
Progression-free survival
Will be estimated using the method of Kaplan-Meier.
Overall survival
Will be estimated using the method of Kaplan-Meier.
Other outcomes
Additional markers of response or resistance
Explore additional markers of response or resistance through hypothesis generating analysis. Tumor mutational burden (TMB) will be evaluated as an exploratory biomarker within each disease cohort. Both the binary cut-point of TMB high/low will be considered as well as TMB as a continuous variable (including log-transformed) will be assessed in a logistic regression model.
