BioNTech Receives FDA Fast Track Designation for its FixVac Candidate BNT111 in Advanced Melanoma

MAINZ, GERMANY, November 19, 2021 — BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) today announced that the U.S. Food and Drug Administration (FDA) granted Fast Track Designation for BNT111, an investigational cancer immunotherapy for the potential treatment of advanced melanoma. BNT111 is the lead product candidate from BioNTech’s fully owned FixVac platform that utilizes a fixed combination of mRNA-encoded, tumor-associated antigens aiming to trigger a strong and precise immune response against cancer. The vaccine candidate is currently being investigated in a Phase 2 trial (EudraCT No.: 2020-002195-12; NCT04526899) in patients with anti-PD-1-refractory/relapsed unresectable Stage III or IV melanoma.

“The Fast Track Designation underlines the potential of our FixVac platform to address current treatment challenges of pre-treated and immune checkpoint blocker experienced melanoma with limited standard of care therapy options left. This is an important step to pave the way for this versatile new treatment approach in a high medical need setting,” said Özlem Türeci, M.D., Co-founder and Chief Medical Officer of BioNTech. “With the Fast Track status and support by the FDA, we aim to expedite the further development of the BNT111 program to provide a new therapeutic option for patients with life-threatening, hard-to-treat melanoma.”

Fast Track is a process designed to facilitate the development, and expedite the review, of new drugs and vaccines that are intended to treat or prevent serious conditions that have the potential to address an unmet medical need. The FDA’s decision is based on available preclinical and clinical data showing the potential of BNT111 to overcome current limitations in the treatment of inoperable therapy-resistant advanced-stage melanoma. With the Fast Track Designation, the development of BNT111 can benefit from more frequent engagement with the FDA, which will support the collection of appropriate data needed to accelerate BNT111’s development.

The ongoing randomized Phase 2 trial (BNT111-01) in patients with anti-PD1-refractory/relapsed unresectable Stage III or IV melanoma investigates BNT111 in combination with Libtayo^® (cemiplimab), an anti-PD-1 monoclonal antibody being co-developed by Regeneron and Sanofi. The BNT111-01 trial which is conducted in collaboration with Regeneron is enrolling a total of 180 patients into three treatment arms in the United States, the United Kingdom, Australia, Spain, Germany, Italy and Poland. This trial seeks to support initial data reported from the ongoing Phase 1 Lipo-MERIT monotherapy dose escalation trial (EudraCT No. 2013-001646-33; NCT02410733; DOI: 10.1038/s41586-020-2537-9) that demonstrated a favorable safety profile and anti-tumor responses of BNT111 alone and in combination with immune checkpoint inhibitor therapy in patients with advanced melanoma.

About BNT111
BNT111 is an intravenous therapeutic cancer immunotherapy candidate encoding a fixed set of four cancer-specific antigens optimized for immunogenicity and delivered as RNA-lipoplex formulation. Based on current data from an exploratory interim analysis of the ongoing Phase 1 Lipo-MERIT monotherapy dose escalation trial, published in Nature, BNT111 induces novel antigen-specific anti-tumor immune responses and enhances pre-existing immune responses against the encoded melanoma-associated antigens (NY-ESO-1, MAGE-A3, tyrosinase, and TPTE), which are expressed in more than 90% of cutaneous melanomas. BNT111 is one of four clinical-stage FixVac product candidates within BioNTech’s development pipeline.

BNT111 is not yet authorized by any regulatory authority and the safety and efficacy has not yet been established.
