Biontech SE and Bristol Myers Squibb Co. are teaming up to develop Biontech’s BNT-327 in a deal possibly worth over $11 billion. BNT-327 is in the hot new class of bispecific antibodies targeting programmed death-1 (PD-1) or its ligand (PD-L1) and vascular endothelial growth factor (VEGF). The bispecifics take advantage of two well established mechanisms of action that help tumors grow; PD-1/PD-L1, which tells immunogenic T cells not to attack the tumor, and VEGF, which tumors excrete to produce new blood vessels to supply oxygen and other nutrients to the tumor.
For the second time in as many months, the lack of statistically significant overall survival data sent shares of Summit Therapeutics Inc. sliding, despite otherwise positive findings for PD-1/VEGF bispecific candidate ivonescimab in non-small-cell lung cancer. But analysts noted the stock reaction overlooks the consistency of the efficacy data to date, as well as the fact that the phase III Harmoni study marks the first pivotal trial testing ivonescimab in a global population.
Epimab Biotherapeutics Inc. licensed out a development-ready KLK2/CD3 bispecific T-cell engager (TCE) for advanced prostate cancer to Juri Biosciences Inc. through a potential $210 million deal.
Teva Pharmaceutical Industries Ltd. has commenced IND-enabling studies with BD-9, a dual-specific multibody targeting thymic stromal lymphopoietin (TSLP) and interleukin-13 (IL-13). By simultaneously blocking two key drivers of TH2-driven inflammation, BD-9 has the potential to improve outcomes for patients with conditions such as atopic dermatitis and asthma.
Although HER2-targeted therapies have become a mainstay in cancer treatment, some tumors evade them by stripping away the portion of the HER2 receptor that most therapies are built to recognize and bind to, but Taiwan’s AP Biosciences Inc. is developing bispecific antibody AP-402 to address treatment-resistant HER2+ cancers.
Investor hopes rose sharply for Merus NV’s phase III trials – data should roll out next year – with bispecific antibody petosemtamab after mid-stage results impressed Wall Street in head and neck squamous cell carcinoma. Shares of Utrecht, the Netherlands-based Merus (NASDAQ:MRUS) jumped, too, closing May 23 at $55.14, up $13.54, or 33%, on interim data as of the Feb. 27 cutoff date.
Interleukin-4 receptor α (IL-4Rα), a shared receptor subunit for both IL-4 and IL-13, along with thymic stromal lymphopoietin (TSLP), are key drivers of the type 2 inflammatory cascade involved in asthma and other inflammatory disorders.
Chronic obstructive pulmonary disease (COPD) is a prevalent and heterogeneous respiratory disorder with limited effective treatments. IL-33 and IL-4Rα are key mediators of airway inflammation in COPD and hence represent potential therapeutic targets.
Although HER2-targeted therapies have become a mainstay in cancer treatment, some tumors evade them by stripping away the portion of the HER2 receptor that most therapies are built to recognize and bind to, but Taiwan’s AP Biosciences Inc. is developing bispecific antibody AP-402 to address treatment-resistant HER2+ cancers.
Pfizer Inc. is paying $1.25 billion up front and up to $4.8 billion in milestone payments to gain global, ex-China rights to SSGJ-707, a PD-1/VEGF bispecific antibody from 3Sbio Inc. that recently won China clearance for a phase III study in lung cancer as a potential first-line monotherapy. Announced after U.S. market hours May 19, the exclusive agreement for SSGJ-707 spells up to $6.15 billion combined for Shenyang, China-based 3Sbio, along with separate tiered double-digit royalty payments on sales of SSGJ-707, if approved.
