BioNTech and DualityBio Receive FDA Fast Track Designation for Antibody-Drug Conjugate Candidate BNT324/DB-1311 in Prostate Cancer

On June 24, 2024 BioNTech SE (Nasdaq: BNTX, "BioNTech") and Duality Biologics (Suzhou) Co., Ltd. ("DualityBio") reported 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 (Press release, BioNTech, JUN 24, 2024, View Source [SID1234644495]). 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 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 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.

G1 Therapeutics Provides Update on Phase 3 PRESERVE 2 Trial in Patients Receiving Trilaciclib Prior to First Line Chemotherapy in Metastatic Triple Negative Breast Cancer (mTNBC)

On June 24, 2024 G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, reported topline results from the final OS analysis of its Phase 3 PRESERVE 2 trial evaluating the efficacy and safety of trilaciclib administered prior to chemotherapy (gemcitabine and carboplatin; GCb) in patients with metastatic TNBC (Press release, G1 Therapeutics, JUN 24, 2024, View Source [SID1234644498]).

The study did not demonstrate a statistically significant treatment effect in the ITT population (n=187) with a hazard ratio (HR) of 0.91 (p=0.884). The median OS in the trilaciclib plus GCb arm was 17.4 months compared to 17.8 months in the control arm. Median OS numerically favored the trilaciclib arm in both PD-L1 subgroups (positive and negative), though neither achieved statistical significance. Varying effects were observed across regions and patients who received different types of subsequent therapies; these findings will be evaluated further. The safety profile of trilaciclib with GCb observed in the trial was consistent with prior studies, and no new safety signals were identified. Consistent with other trilaciclib studies, evidence of myeloprotection was observed, including a reduction in the occurrence of severe neutropenia, which occurred in 8% of patients who received trilaciclib compared to 29% of patients in the control arm. The Company will submit the results of this trial to a future medical conference.

"The unexpected results from PRESERVE 2 underscore the challenge of developing new therapies for triple negative breast cancer," said Jack Bailey, Chief Executive Officer of G1 Therapeutics. "We are disappointed that this trial did not deliver the benefit that we anticipated to people living with TNBC. We are also grateful to the patients who participated in this trial, their families, and their healthcare teams including the clinicians and their staff."

Mr. Bailey continued, "We will now further our focus on both accelerating and expanding the growth of the ES-SCLC business to achieve anticipated company profitability in the second half of 2025 and evaluating other myeloprotection uses for trilaciclib. We are also pursuing ex-US partners to expand the use of COSELA (trilaciclib) globally."

Financial Guidance

G1 today reaffirmed its full year 2024 COSELA net revenue guidance and updated its cash runway guidance. G1’s guidance is based on current expectations for continued sales growth of COSELA in the U.S. and achievement of its forecasts.

The Company expects to generate between $60 million and $70 million in COSELA net revenue in 2024. Additionally, G1 plans to wind down the Phase 3 PRESERVE 2 trial, discontinue the anticipated hiring of staff and investment for a 1L TNBC indication and make targeted headcount reductions outside of the existing commercial organization to streamline the Company. These efforts are expected to provide sufficient cash runway to achieve anticipated company profitability in the second half of 2025.
