GSK plc is the latest pharma giant to bite the “magic bullet” of antibody-drug conjugate (ADC) drugs, promising to pay the Chinese immunotherapy developer Hansoh Pharmaceutical Co. Ltd. $85 million up front and over $1.4 billion in milestone payments in a licensing deal for HS-20089.
Deals involving antibody-drug conjugate (ADC) therapies continue to gain momentum with Daiichi Sankyo Co. Ltd. and Merck & Co. Inc. the latest firms to team up on global development and commercialization activities, as Daiichi offers up rights to three of its potentially first-in-class ADC candidates for $22 billion, making it the largest ADC agreement to date.
Structure-guided lead optimization at Merck & Co. Inc. has led to the discovery of MK-1084 as a highly potent and selective KRAS G12C-GDP inhibitor. As reported at the recent AACR-NCI-EORTC conference, the candidate demonstrated an excellent off-target and ion channel profile, with low potential for bile salt export pump (BSEP) inhibition.
Biopharma companies and industry advocates received the message the U.S. FTC intended to send when it broke new antitrust ground earlier this year in challenging Amgen Inc.’s $27.8 billion acquisition of Horizon Therapeutics plc. Now they’re uniting to send a message of their own – in the guise of an awareness campaign showing that the FTC’s new approach to M&A reviews and antitrust enforcement will undermine the ecosystem responsible for innovative and important therapies the world over.
Upbeat phase III findings outweighed less encouraging late-stage trial news, as big pharma provided a mixed bag of cancer findings – with one data batch to form the basis of global approval bids, as Astrazeneca plc with Daiichi Sankyo Co. Ltd. unveiled interim results from a study called Tropion-Breast01. Targeting trophoblast cell surface antigen 2, datopotamab deruxtecan (dato) hit the mark in progression-free survival for patients with hormone receptor-positive, HER2-low or negative breast cancer in the study called Tropion-Breast01.
Merck & Co. Inc. is pledging major resources on its prospect in the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor space with a phase III program that together will enroll about 17,000 subjects and test oral peptide MK-0616’s effect on tackling low-density lipoprotein cholesterol.
Boehringer Ingelheim GmbH is the latest company to dive into the legal fray surrounding the federal government’s plan to change drug costs. The drug price negotiation program established by the Inflation Reduction Act is “unlawful,” according to the company’s brief, because it violates the due process clause and the just-compensation portion of the U.S. constitution’s Fifth Amendment.
Targeting the adenosine A2A receptor, a critical mediator of immunosuppression on the tumor microenvironment, has emerged as a strategy to improve cancer immunotherapy, and several A2A receptor antagonists are under clinical evaluation both as monotherapy and in combination with checkpoint inhibitors.
Researchers at Merck & Co. Inc. have presented the discovery of novel selective metabotropic glutamate receptor 2 (mGluR2) negative allosteric modulators (NAMs) as potential PET imaging agents. Synthesis and optimization of a series of analogues of a potent and selective mGluR2 NAM resulted in the identification of compound MK-8056 as a high-affinity mGluR2 NAM (Ki=0.19 nM) with desirable lipophilicity (logD7.0=2.46) and low P-gp susceptibility.
