HER2-targeting bispecific antibody zanidatamab, in development by Jazz Pharmaceuticals plc and Zymeworks Inc., produced better antitumor responses than current standard of care when used as a second-line treatment for biliary tract cancer (BTC) in a pivotal phase IIb study, bringing it closer to becoming the first therapy to target HER2-expressing BTC.
Roche AG acquired global rights to Zion Pharma Ltd.’s lead program, ZN-A-1041, an orally administered selective tyrosine kinase inhibitor that is designed to penetrate the blood-brain barrier and can prevent and treat brain metastases in HER2-positive metastatic breast cancer patients.
HER2 is a member of the epidermal growth factor receptor family that is overexpressed in approximately 20% of breast cancers. Trastuzumab, an anti-HER2 antibody discovered 25 years ago has become the standard of care treatment due to its beneficial results.
The U.S. FDA granted accelerated approval to Seagen Inc. on Jan. 19 for Tukysa (tucatinib), extending the therapy’s reach beyond HER2-positive metastatic breast cancer, and clearing its way for RAS wild-type, HER2-positive unresectable or metastatic colorectal cancer.
The State University of New York has presented new antibody-drug conjugates (ADCs) consisting of trastuzumab antibody targeting human epidermal growth factor receptor 2 (HER2) covalently linked to Toll-like receptor 7 (TLR7) and/or TLR8 agonists through a linker reported to be useful for the treatment of cancer and infections.
Abpro Corp. and Celltrion Healthcare Inc. entered a global partnership valued at up to $1.75 billion involving ABP-102, a bispecific antibody targeting HER2-positive cancers, a move Abpro CEO Ian Chan said would help “accelerate this type of therapy for patients in need.”
Abpro Corp. and Celltrion Healthcare Inc. entered a global partnership valued at up to $1.75 billion involving ABP-102, a bispecific antibody targeting HER2-positive cancers, a move Abpro CEO Ian Chan said would help “accelerate this type of therapy for patients in need.” With ABP-102 in preclinical development, Abpro decided to start looking for a partner. HER2 is “one of the biggest targets in biotech, mostly relevant for breast, colorectal and gastric cancers,” Chan told BioWorld. “Celltrion happened to have a lot of experience in the space.”
Mersana Therapeutics Inc. is getting $100 million up front in an option deal with GSK plc for preclinical-stage antibody-drug conjugate (ADC) XMT-2056, which could bring up to $1.36 billion more in an option exercise payment, development, regulatory and commercial milestones. It’s the second potential $1 billion-plus ADC deal for Cambridge, Mass.-based Mersana in 2022 and the first for its Immunosynthen platform, which uses a STING agonist payload specifically designed for ADCs.
The “showdown” at the American Society of Clinical Oncology (ASCO) meeting foreseen by one analyst between breast cancer drugs from Gilead Sciences Inc. and Astrazeneca plc with partner Daiichi Sankyo Co. Ltd. didn’t quite materialize.
Could Merus NV be on course to get the fourth “tumor agnostic” drug approved, a groundbreaking approach to cancer that focuses on mutations rather than location of the disease? According to a trial update revealed at the American Society of Clinical Oncology (ASCO) conference the biotech from Utrecht, the Netherlands, could join Merck & Co Inc., Bayer AG/Eli Lilly and Co. and Roche Holding AG with its early-to-mid stage candidate, zenocutuzumab.
