HB-201 and HB-202 are study drugs which are designed to train the body to recognize and fight substances found in HPV16+ cancer. This trial studies the safety and anti-cancer effect of HB-201 and HB-202 in people. HPV is a group of more than 200 related viruses, each given a number. HPV 16 is one of the highest risk groups for HPV-related cancers.
The trial enrolls patients with metastatic/recurrent HPV 16+ head and neck squamous cell 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 also enrolls patients who have HPV 16+ head and neck cancers who have received prior therapy in metastatic/recurrent setting (2L+). Patients will receive the study drugs alone or in addition to their pembrolizumab standard of care treatment.
