Citing a high rate of patients leaving the study, Merck & Co. Inc. has discontinued the anti-TIGIT antibody vibostolimab and the anti-PD-1 Keytruda (pembrolizumab) portion of it phase III Keyvibe-10 trial as an adjuvant treatment for those with resected high-risk melanoma.
Amid intensifying competition in the PD-1/PD-L1 checkpoint space, Samsung Bioepis Co. Ltd. kicked off a phase I study of SB-27, a biosimilar of Merck & Co Inc.’s blockbuster immunotherapy, Keytruda (pembrolizumab), for lung cancer. Posted on clinicaltrials.gov on Feb. 20, the randomized, double-blind, three-arm, parallel group and multicenter phase I study will examine the pharmacokinetics, efficacy and safety of SB-27 against an EU-sourced and U.S.-sourced Keytruda in 135 patients with non-small-cell lung cancer.

Shanghai-based Henlius Biotech Inc. and India’s Intas Pharmaceuticals Ltd. agreed upon a potential €185 million (US$195.38 million) licensing deal for Intas to develop and sell Henlius’ China NMPA-approved lung cancer drug, serplulimab, across Europe and India. Serplulimab (HLX-02) is a recombinant humanized PD-1 monoclonal antibody (MAb) injection that first gained approval as Hansizhuang in March 2022.

Immutep Ltd.’s lead candidate, eftilagimod (IMP-321, efti), a lymphocyte activation gene-3 (LAG-3) fusion protein and major histocompatibility complex class II agonist, delivered an overall survival benefit of 35.5 months in the TACTI-002 trial that combined efti with Merck & Co. Inc.’s Keytruda (pembrolizumab) as first-line treatment of non-small-cell lung cancer (NSCLC) at two years follow-up.
The narrative of TIGIT-targeting immunotherapy development, beset by negative news in recent months, has found a positive plotline again, thanks to what Roche Holding AG referred to as “an inadvertent disclosure” of a second interim analysis from the phase III Skyscraper-01 study testing anti-TIGIT candidate tiragolumab with anti-PD-L1 antibody Tecentriq (atezolizumab) in non-small-cell lung cancer.
About two months ahead of the planned PDUFA date, the U.S. FDA has granted expanded approval of PD-1 antibody Jemperli (dostarlimab) from partners Anaptysbio Inc. and GSK plc for use in combination with standard-of-care chemotherapy. GSK said the drug would be the only frontline immuno-oncology treatment for endometrial cancer available in combination with carboplatin and paclitaxel. The supporting supplemental BLA for the expanded indication previously received priority review.
B cells that expressed a constellation of checkpoint inhibitors could be spurred into antitumor activity by deleting or blocking the checkpoint molecule T-cell immunoglobulin and mucin domain 1 (TIM-1). The findings, which were published online in Nature on June 21, 2023, suggest ways to bring B cells into the antitumor fight. More broadly, Lloyd Bod told BioWorld, his laboratory aims to “break the dogma that B cells only produce antibodies.”
A group of scientists from the Center for Stem Cell and Translational Immunotherapy, Brigham and Women’s Hospital at Harvard Medical School have developed an antitumor immunotherapy that uses oncolytic viruses and stem cells for the treatment of metastatic brain melanoma.
