On May 25, 2023 ISA reported that it will present the first clinical data of the combination of ISA101b and Regeneron’s PD-1 inhibitor Libtayo (cemiplimab) in patients with recurrent metastatic Human Papilloma Virus type 16 (HPV16) induced head and neck cancers who progressed on pembrolizumab or nivolumab (Press release, ISA Pharmaceuticals, MAY 25, 2023, View Source [SID1234632062]).

Patients with recurrent and/or metastatic HPV16 positive OPC who experienced disease progression during or within 6 months after prior anti-PD1 therapy were to be treated until disease progression or withdrawal. Patients that never responded to prior treatment were also included. Further information can be found on clinicaltrials.gov (NCT04398524). Recruitment in this study is ongoing; results of the complete trial will become available mid-2024.
Presentation Title: Phase 2 study of ISA101b (peltopepimut-S) and cemiplimab in patients with advanced HPV16+ oropharyngeal cancer who failed anti-PD-1 therapy
Presentation Details: Monday 5th June 2023, 1:15-4:15pm CDT
Presenting Author: Dr. Anthony Kong, Principal Investigator
Session (poster): Head and Neck Cancer
ISA101b immunotherapy targets human papillomavirus type 16 (HPV16) positive cancers. It induces strong and specific immune responses to the HPV16 virus, and (re-)establishes a powerful and targeted T-cell immune response against infected and/or cancerous cells and tissues. Re-ignition of an anti-tumor effect of anti-PD1 therapy after failure of checkpoint inhibition by the addition of a therapeutic vaccine is a unique feature.
Head-and-neck cancer can be a severe and life-threatening disease. HPV16 is a major cause of head-and-neck cancer. Recurrent and metastatic HPV16 positive OPC is a form of head-and-neck cancer with a high unmet medical need. In September 2021 the U.S. Food and Drug Administration (FDA) granted Fast Track designation to ISA101b for the treatment of recurrent and metastatic HPV16 positive OPC.
