a study hb-201 in patients with newly diagnosed hpv16+ oropharynx or locally advanced cervical cancer

Conditions: HPV 16+ Confirmed Oropharynx Cancer and Cervical Cancer

Summary: this window of opportunity clinical trial will examine the immunologic effects of the study agent hb-201 in the head and neck or cervical cancer, when administered by iv route.

the window of opportunity, study h-200-002, will examine the effects of study agent (hb-201) on subjects during the "window" between diagnosis of their cancer and their definitive cancer surgery or chemoradiation. the study will be a 2-arm study design. in arm 1, the study will enroll subjects with resectable stage i-iii human papillomavirus 16 positive (hpv 16+) genotype squamous cell cancer of the oropharynx or unknown primary cancer site who are candidates for transoral surgery. participants will receive a single intravenous dose of the study agent hb-201 prior to transoral surgery administered intravenously. in arm 2, the study will enroll cervical cancer subjects who have histologically confirmed newly diagnosed advanced squamous cell carcinoma, adenocarcinoma, and/ or adenosquamous cell carcinoma with hpv 16+ genotype clincal stages ib to ivb with plan for initial treatment of definitive chemoradiation. participants will receive a single intravenous dose of hb-201 prior to the start of chemoradiation.
