BioNTech and DualityBio Receive FDA Fast Track Designation for Antibody-Drug Conjugate Candidate BNT324/DB-1311 in Prostate Cancer
BioNTech and DualityBio's BNT324/DB-1311, an antibody-drug conjugate (ADC) targeting B7-H3, has received FDA Fast Track designation for treating advanced/metastatic castration-resistant prostate cancer (CRPC). This designation, based on preclinical and Phase 1/2 clinical data demonstrating antitumor activity and a manageable safety profile, facilitates more frequent FDA interactions and expedited regulatory review. CRPC patients, who often face poor prognosis with a 5-year survival rate of 36%, may benefit from this development. All three ADC candidates under BioNTech-DualityBio collaboration have now received FDA Fast Track designation, indicating the promise of their ADC technology.
- BNT324/DB-1311 received FDA Fast Track designation.
- Phase 1/2 trial data shows antitumor activity and manageable safety profile.
- Frequent FDA engagement and expedited regulatory review.
- All three ADC candidates in BioNTech-DualityBio's collaboration have FDA Fast Track designation.
- Advanced CRPC has a poor prognosis with a 5-year survival rate of only 36%.
Insights
The FDA's Fast Track designation for BNT324/DB-1311 underscores the serious unmet need in advanced castration-resistant prostate cancer (CRPC). This ADC targets B7-H3, an immune checkpoint protein implicated in tumor progression. The Phase 1/2 trial's preliminary data indicates antitumor activity and a manageable safety profile, which are promising signs. The designation means faster dialogue with the FDA, potentially expediting approval if the results remain positive.
For patients, this could mean an innovative treatment option tailored to this aggressive cancer type. However, it’s important to remember that early-phase trial results need to be confirmed in larger, later-phase trials before the broader clinical community will accept them.
Rating: 1
This Fast Track designation is a positive catalyst for both BioNTech and DualityBio. It enhances the likelihood of a quicker path to market, which can translate to earlier revenue streams for the companies. Notably, this is the third ADC in their collaboration to receive such designation, indicating a strategic and potentially lucrative portfolio of cancer treatments.
From an investor's perspective, BioNTech's stock could see a positive short-term impact due to increased investor confidence. The long-term financial implications will depend on the eventual market approval and the competitive landscape at the time of launch. Additionally, partnerships and strategic collaborations will be key in broadening the financial base for further development and distribution.

- Prostate cancer is the second leading cause of cancer-related deaths among men worldwide3 often diagnosed at advanced disease stages; patients with metastatic castration–resistant prostate cancer (“mCRPC”), an advanced form of prostate cancer, have a 5-year survival rate of around
36% 4 - All three clinical stage antibody-drug conjugate (“ADC”) candidates in BioNTech’s and DualityBio’s strategic collaboration have received FDA Fast Track designation supporting the potential of the companies’ ADC technology
MAINZ, Germany and SHANGHAI, China, June 24, 2024 – BioNTech SE (Nasdaq: BNTX, “BioNTech”) and Duality Biologics (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) 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
“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 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 in patients with metastatic breast cancer. The BNT323/DB-1303 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, 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) in patients with advanced or metastatic solid tumors.
