U.S. FDA and CEL-SCI Agree on Use of PD-L1 Biomarker to Select Head and Neck Cancer Patients for Marketing Registration Study to Commence Q1 2025
- Biomarker used to select patients who are more likely have favorable outcomes, supporting a successful confirmatory Registration Study

“To our knowledge, Multikine is the only neoadjuvant immunotherapy that has shown overall survival benefit in the low and negative PD-L1 head and neck cancer population. This underscores the critical importance of having reached an agreement with the FDA on the method for identifying and selecting patients with low PD-L1 tumor expression for our upcoming confirmatory Registration study,” stated CEL-SCI CEO Geert Kersten.
“Patient selection based on low PD-L1 as a biomarker can boost the success of our upcoming confirmatory trial, further enhancing our confidence based on the retrospective data from our Phase 3 study. We appreciate the ongoing dialog, exchange of ideas and information with the FDA in support of CEL-SCI’s groundbreaking work as we aim to treat an unmet need in cancer patients with low PD-L1 expression.”
About CEL-SCI Corporation
CEL-SCI believes that boosting a patient’s immune system while it is still intact should provide the greatest possible impact on survival. Multikine is designed to help the immune system "target" the tumor at a time when the immune system is still relatively intact and thereby thought to be better able to mount an attack on the tumor.
Multikine (Leukocyte Interleukin, Injection), a true first-line cancer therapy, has been dosed in over 740 patients and received Orphan Drug designation from the FDA for neoadjuvant therapy in patients with squamous cell carcinoma (cancer) of the head and neck. Based on the very strong data from the completed randomized controlled Phase 3 study, the FDA concurred with CEL-SCI’s target patient selection criteria and gave the go-ahead to conduct a small, focused, confirmatory Registration Study which will enroll 212 patients. CEL-SCI will enroll newly diagnosed locally advanced primary treatment naïve resectable head and neck cancer patients with no lymph node involvement (determined via PET scan) and with low PD-L1 tumor expression (determined via biopsy), representing about 100,000 patients annually.
