Multicentric Randomized Phase I/IIa Trial of the Safety and Immunogenicity of a Therapeutic Anti-HPV DC Targeting Vaccine in Patients With Human Papillomavirus (HPV)-Positive Oropharyngeal Cancer
This study is a multicentric double-blind placebo-controlled dose escalation trial of a CD40HVac vaccine (humanized anti-CD40 mAb fused to HPV16 E6/E7 oncoproteins) adjuvanted with poly-ICLC (Hiltonol) in patients with HPV16 oropharyngeal carcinoma with no evidence of residual or recurrent disease after surgery and/or radiochemotherapy. The primary objective is to determine the recommended phase 2 dose (RP2D) of a poly-ICLC(Hiltonol)-adjuvanted CD40HVac vaccine according to the safety and the capacity to elicit immune responses of different doses Two dose levels of poly-ICLC-adjuvanted CD40.HVac will be explored * 1st dose level: CD40.HVac 1.0 mg, with 1.0 mg poly-ICLC * 2nd dose level: CD40.HVac 3.0 mg, with 1.0 mg poly-ICLC The safety data will be reviewed by an IDSMB that will give recommendations.
