Study of Nivolumab Plus Ipilimumab in Patients With Salivary Gland Cancer

Inclusion Criteria

• Cohort 1 only: Patients must have pathologically or cytologically confirmed adenoid cystic carcinoma. Cancers arising from non-salivary gland primary sites are allowed.
• Patients must have pathologically or cytologically confirmed salivary gland cancer of any histology except for adenoid cystic carcinoma.
• Patients must have recurrent and/or metastatic disease not amenable to potentially curative surgery or radiotherapy.
• At least 2 weeks must have elapsed since the end of prior systemic treatment and/or 4 weeks since completion of radiotherapy with resolution of all treatment-related toxicity to NCI CTCAE Version 4.0 grade ≤1 (or tolerable grade 2) or back to baseline (except for alopecia, lymphopenia, or hypothyroidism) prior to starting study drug treatment. Any number of prior therapies for recurrent/metastatic salivary gland cancer are allowed.

NOTE: Patients previously treated with hormonal therapies (e.g., drugs targeting the androgen receptor) may continue these drugs prior to trials enrollment and concomitantly with study therapy.

• Patients must have RECIST v1.1 measurable disease.
• Cohort 1 and acinic cell carcinoma patients in Cohort 2 only: Patients must have documentation of a new or progressive lesion on a radiologic imaging study performed within 6 months prior to study enrollment (progression of disease over any interval is allowed) and/or new/worsening disease related symptoms within 6 months prior to study enrollment. Note: This assessment will be performed by the treating investigator. Evidence of progression by RECIST criteria is not required.
• Age ≥ 18 years.
• ECOG performance status 0 or 1 (or Karnofsky ≥ 70%).
• Patients must have tissue from the primary tumor or metastases available for correlative studies. Either a paraffin block or at least 20 unstained slides are acceptable (30 unstained slides would be ideal). (If less than twenty unstained slides are available and a paraffin bloc is not available, the patient may be able to participate at the discretion of the investigator.)
• Patients must agree to undergo two research biopsies of malignant lesions. Tumor tissue obtained prior to study consent or treatment as part of standard of care can also be submitted in lieu of performance of the first pre-treatment biopsy, if the Principal Investigator deems it to be of sufficient quantity/quality/timeliness. Patients may be exempt from biopsy if 1) the investigator or person performing the biopsy judges that no tumor is accessible for biopsy, 2) the investigator or person performing the biopsy feels that the biopsy poses too great of a risk to the patient, or 3) the patient's platelet count is 9.0 g/dL
• AST/ALT ≤ 3 x ULN
• Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin 10 mg/day prednisone equivalents) or other immunosuppressive medications within 2 weeks of study drug administration. NOTE: Subjects are permitted to use topical, ocular, intra-articular, intranasal, and inhalational corticosteroids (with minimal systemic absorption). Physiologic replacement doses of systemic corticosteroids are permitted, even if >10 mg/day prednisone equivalents. A brief course of corticosteroids for prophylaxis (e.g., contrast dye allergy) or for treatment of non-autoimmune conditions (eg, delayed-type hypersensitivity reaction caused by contact allergen) is permitted.
• Active, known, or suspected autoimmune disease within the past 2 years. NOTE: Subjects are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger
• Patients should be excluded if they have had prior systemic treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell costimulation or i
