Genescience Pharmaceuticals Co. Ltd. has identified fibroblast growth factor receptor 2 (FGFR2) and/or FGFR3 inhibitors reported to be useful for the treatment of cancer, osteochondrodysplasia and achondroplasia.
Despite an outcome that TD Cowen analyst Tyler Van Buren called ”fantastic,” shares of Tyra Biosciences Inc. (NASDAQ:TYRA) closed Oct. 25 at $21.93, down $6.68, or 23%, as Wall Street digested new phase I/II data with FGFR3 inhibitor TYRA-300 in metastatic urothelial cancer from the Surf301 phase I/II study in progress.
Insilico Medicine Inc. has synthesized fibroblast growth factor receptor 2 (FGFR2) and/or FGFR3 inhibitors reported to be useful for the treatment of cancer.
Hainan Simcere Pharmaceutical Co. Ltd. has prepared bicyclic compounds acting as fibroblast growth factor receptor 3 (FGFR3) inhibitors potentially useful for the treatment of cancer.
Hypochondroplasia (HCH) is a skeletal dysplasia similar to achondroplasia (ACH) but with milder features, that affects particularly the ossification of proximal long bones of arms and legs. Around 70% to 80% of cases of HCH are caused by N540K alterations in the FGFR3 gene. At the recent 6th Annual Achondroplasia & Skeletal Dysplasia Research Conference, researchers from Tyra Biosciences Inc. presented preclinical proof-of-concept data of TYRA-300, an oral FGFR3-selective inhibitor in a model of HCH.
Hainan Simcere Pharmaceutical Co. Ltd. has patented fibroblast growth factor receptor 3 (FGFR3) inhibitors reported to be useful for the treatment of cancer.
Positive results from Bridgebio Pharma Inc.’s phase II study of infigratinib in children with achondroplasia, a genetic disease that inhibits bone length and leads to short stature, prompted the company stock to surge. Participants receiving the highest dosage, which was the fifth cohort getting 0.25 mg/kg daily, saw a 3.03-centimeter increase, about 1.19 inch, in their height annually, which produced a “p” value of 0.0022.
Tyra Biosciences Inc. is expanding development of TYRA-300 into achondroplasia based on promising preclinical results from a study conducted in collaboration with the Imagine Institute. A specific mutation in fibroblast growth factor receptor 3 (FGFR3) causes over 97% of achondroplasia.
Inhibition of emerging polyclonal on-target acquired resistance mutations remains a critical unmet need in the treatment of fibroblast growth factor receptor 2 (FGFR2)-driven tumors. In the current study, researchers from Tyra Biosciences Inc. presented the preclinical characterization of a novel FGFR1/2/3 inhibitor, TYRA-200, being developed for the treatment of cancer.
