safety profile demonstrated by preliminary Phase 1/2 clinical data from
patients with advanced or metastatic solid tumors(1)(,)(2)

MAINZ, Germany and SHANGHAI, China, June 24, 2024 - BioNTech SE
(https://www.biontech.com/int/en/home.html) (Nasdaq: BNTX, "BioNTech") and
Duality Biologics (https://www.dualitybiologics.com/welcome.html) (Suzhou) Co.,
Ltd. ("DualityBio") today announced that the U.S. Food and Drug Administration
("FDA") granted Fast Track designation for BNT324/DB-1311 for the treatment of
patients with advanced/unresectable, or metastatic castration-resistant prostate
cancer ("CRPC") who have progressed on or after standard systemic regimens.
BNT324/DB-1311 is a next-generation antibody-drug conjugate ("ADC") candidate
targeting the transmembrane glycoprotein B7-H3, an immune checkpoint protein
which is overexpressed in a range of tumor types and has been associated with
disease progression and poor prognosis for patients. The candidate is currently
being evaluated in an ongoing Phase 1/2 study (NCT05914116)
(https://classic.clinicaltrials.gov/ct2/show/NCT05914116) in patients with
advanced solid tumors.
"The FDA's decision is a recognition of the potential of our B7-H3-targeting ADC
candidate for the treatment of advanced CRPC. While patients with metastatic
prostate cancer initially respond to hormone therapy, most patients progress
after 18-24 months and develop CRPC, an advanced form of prostate cancer,
leading to a poor prognosis for these patients. The 5-year survival rate for
patients with metastatic CRPC is only around 36%," said Prof. Özlem Türeci,
M.D., Chief Medical Officer and Co-Founder at BioNTech. "We are committed to
further advancing BNT324/DB-1311 with our partner DualityBio and believe that a
targeted ADC immunotherapy approach has the potential to improve outcomes for
patients at advanced stages of the disease."
"BNT324/DB-1311 is the third asset in our strategic collaboration which has
received FDA Fast Track designation, highlighting the potential of the candidate
to fill an unmet medical need for novel treatment options for B7-H3 expressing
cancers," said Vivian Gu, M.D., Chief Medical Officer at DualityBio.
"Preliminary data from our ongoing Phase 1/2 trial has demonstrated antitumor
activity and a manageable safety profile of BNT324/DB-1311 in patients with
advanced solid tumors. With the designation and support by the FDA, we seek to
expedite further development of BNT324/DB-1311."
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 and have the potential to address an unmet medical need. The
designation is based on preliminary safety and efficacy data from an ongoing
Phase 1/2 trial with BNT324/DB-1311 in patients advanced or metastatic solid
tumors. With the Fast Track designation, the development of BNT324/DB-1311 can
benefit from more frequent engagement with the FDA, to support the development
and expedite the regulatory review of BNT324/DB-1311.
All three clinical stage ADC candidates in BioNTech's and DualityBio's global
strategic partnership (https://investors.biontech.de/news-releases/news-release-
details/biontech-and-dualitybio-form-global-strategic-partnership) have received
FDA Fast Track designation. The lead candidate in the collaboration, BNT323/DB-
1303, a next-ADC candidate targeting the Human Epidermal Growth Factor Receptor
2 ("HER2"), is being evaluated in a Phase 1/2 trial in patients with advanced
solid tumors and a global Phase 3 clinical trial
(https://investors.biontech.de/news-releases/news-release-details/biontech-and-
dualitybio-initiate-pivotal-phase-3-trial-antibody) in patients with metastatic
breast cancer. The BNT323/DB-1303 (https://investors.biontech.de/news-
releases/news-release-details/biontech-and-dualitybio-receive-fda-breakthrough-
therapy) program received the Fast Track designation and Breakthrough Therapy
designation from the FDA for the treatment of endometrial cancer in 2023. In
January 2024, the companies' ADC candidate targeting the trophoblast cell-
surface antigen 2 ("TROP2"), BNT325/DB-1305 (https://investors.biontech.de/news-
releases/news-release-details/biontech-and-dualitybio-receive-fda-fast-track-
designation-next), received FDA Fast Track designation for the treatment of
patients with platinum-resistant ovarian epithelial cancer.
About BNT324/DB-1311
BNT324/DB-1311 is a next-generation topoisomerase-I-inhibitor-based ADC
candidate targeting the immune checkpoint protein B7-H3. The transmembrane
glycoprotein B7-H3 plays a critical role in the anti-tumor immune response and
the shaping of the tumor microenvironment. It is overexpressed in a range of
solid tumors, with limited expression in healthy tissues, and has been
associated with disease progression and very poor prognosis.(5) Preclinical
studies have shown that BNT324/DB-1311 exhibits antitumor activity in various
solid tumor models.(2) Preliminary data from the ongoing Phase 1/2 trial has
demonstrated antitumor activity and a manageable safety profile for BNT324/DB-
1311 in patients with advanced solid tumors.(1) BNT324/DB-1311 is currently
being evaluated in a Phase 1/2 clinical trial (NCT05914116
(https://classic.clinicaltrials.gov/ct2/show/NCT05914116)) in patients with
advanced or metastatic solid tumors.
