ClinicalTrials ID:NCT04180215

Patient View

This Phase 1/2 study evaluates the safety and efficacy of HB-201 and HB-202 in HPV16+ cancers. It includes dose escalation and expansion phases, enrolling patients with metastatic/recurrent head and neck cancer eligible for pembrolizumab. Interventions involve HB-201 and HB-202, alone or with pembrolizumab, using a 3+3 dose escalation method.

Patient Parameters

Program Overview

This is a First in Human (FIH) Phase I/II, multinational, multicenter, open-label study of HB-201 single vector therapy and HB-201 & HB-202 two-vector therapy in patients with HPV 16+ confirmed cancers comprising two parts: Phase I Dose Escalation and Phase II Dose Expansion.

Description

HB-201 and HB-202 are study drugs which are designed to train the body to recognize and fight substances found in HPV 16+ cancer. This trial studies the safety and anti-cancer effect of HB-201 and HB-202 in people.

The trial is enrolling patients with metastatic/recurrent head and neck cancer who have not yet received treatment in this setting (1L, first line) and who are eligible to receive pembrolizumab as part of their standard of care. This trial is also enrolling patients with metastatic/recurrent head and neck who have received prior treatment in this setting (2L+, second and later line) who are eligible to receive pembrolizumab as part of their standard of care. Patients will receive the study drugs in addition to their pembrolizumab standard of care regimen.
