Current treatments for Graves’ hyperthyroidism (GH) and Graves’ orbitopathy (GO) are ineffective. Researchers assessed the preclinical in vitro efficacy of SYD-5115 (Byondis BV), a novel low-molecular-weight thyrotropin receptor (TSH-R) antagonist. The compound comprises an N-acetylated dihydropyrrole pyrimidine core with various substituents, including a difluorinated-spirocyclohexyl ring and a chiral carbamate group on the pyrimidine ring.
Researchers from Byondis BV and Sanquin Bloedvoorziening have published preclinical data on a new signal-regulatory protein α (SIRPα)-directed antibody, BYON-4228.
Byondis BV is gearing up for a U.S. filing of an antibody-drug conjugate (ADCs) in advanced HER2-positive breast cancer, but CEO Marco Timmers has grand plans to partner up with big pharma and expand into other diseases.
