Oropharynx Cancer clinical trials at UCSD

This will be a blinded, placebo-controlled, randomized, phase 2 study in which subjects will be randomly assigned 1:1 to cemiplimab plus placebo or cemiplimab plus ISA101b.

This is a prospective, multi-center, open-label, non-randomized, multi-arm phase II trial to evaluate the efficacy of combination therapy with pembrolizumab and cetuximab for patients with recurrent/metastatic HNSCC. There will be four patient cohorts, including a PD-1/PD-L1 inhibitor-naïve, cetuximab-naïve arm (Cohort 1), a PD-1/PD-L1 inhibitor-refractory, cetuximab-naïve arm (Cohort 2), a PD-1/PD-L1 inhibitor-refractory, cetuximab-refractory arm (Cohort 3), and a cutaneous HNSCC arm (Cohort 4). A total of 83 patients (33 in Cohort 1, 25 in Cohort 2, 15 in Cohort 3, and 10 in Cohort 4) will be eligible to enroll. Patients will be enrolled at 4 sites: UC San Diego Moores Cancer Center, UC Los Angeles Jonsson Comprehensive Cancer Center, University of Michigan Comprehensive Cancer Center, and University of Washington Siteman Cancer Center.

This is a single-arm, multi-site, open-label trial of pembrolizumab (MK-3475) used in combination with standard, cisplatin-based, definitive chemoradiotherapy (CRT) in patients with stage III-IVB squamous cell carcinoma of the head and neck (SCCHN). Approximately 39 patients with Stage III-IVB SCCHN will be enrolled to evaluate both the safety and efficacy of this novel combination. Subjects will not be randomized and will all receive the study treatment. Treatment will consist of a loading dose of pembrolizumab 200 mg IV given 7 days prior to initiation of CRT (day-7). CRT with cisplatin 40 mg/m2 IV weekly and head and neck radiation at 70 Gy fractionated at 2 Gy once daily over 35 days, will begin on day 1. CRT will end on approximately day 46-50. Pembrolizumab 200 mg IV will continue following CRT in an adjuvant fashion starting on day 57 for an additional 5 doses, as tolerated, through day 141. Subjects will be evaluated for response following treatment.

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether radiation therapy is more effective with cisplatin or cetuximab in treating oropharyngeal cancer. PURPOSE: This phase III trial is studying radiation therapy with cisplatin or cetuximab to see how well it works in treating patients with oropharyngeal cancer.
