To address the dual bottlenecks of immunosuppressive cell infiltration and impaired T-cell function in the tumor microenvironment (TME), researchers from the School of Pharmaceutical Sciences of Sun Yat-sen University (China) aimed to develop an engineered bispecific peptide-nanozyme conjugate (BsPNEC) targeting PD-L1 and CXCR1/2.
Programmed death-ligand 1 (PD-L1) is a crucial immune checkpoint ligand that inhibits antitumor immunity by engaging PD-1 on T cells, and checkpoint blockade has become a pillar of anticancer therapy. However, many patients show limited treatment responses.
Crescent Biopharma Inc. teamed with Sichuan Kelun-Biotech Biopharmaceutical Co. Ltd. to generate “parallel” data of its PD-1/VEGF bispecific antibody, CR-001. The goal is to get 2027 readouts of the bispecific as a monotherapy and as a combination therapy with antibody-drug conjugates in both the U.S. and China.

Laigo Bio BV has raised €11.5 million (US$13.7 million) in a seed round for the further development of a new approach to inducing targeted protein degradation by E3 ubiquitin ligases.

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.
A year after manufacturing issues resulted in a complete response letter for cosibelimab, the U.S. FDA approved Checkpoint Therapeutics Inc.’s drug, branded Unloxcyt, as the first anti-PD-L1 antibody for use in metastatic or locally advanced cutaneous squamous cell carcinoma patients who are not candidates for curative surgery or curative radiation.
Researchers from Suzhou Siran Biotech Co. Ltd. presented the discovery and preclinical characterization of SA-1211, an N-acetylgalactosamine (GalNAc)-conjugated siRNA dimer targeting both hepatitis B virus (HBV) and PD-L1 gene expression, being developed as a potential new therapeutic candidate for the treatment of chronic hepatitis B (CHB).
Biontech SE is extending its relationship with Biotheus Inc. from a licensing deal to a full-scale acquisition, agreeing to pay $800 million cash and up to $150 million in milestone payments for the Chinese oncology specialist.
