Overview

We are a clinical-stage biotechnology company focused on developing next-generation precision medicines for large opportunities in targeted oncology and genetically defined conditions, with an initial focus on Fibroblast Growth Factor Receptor (FGFR) biology.  

Our in-house precision medicine platform, SNÅP, enables rapid and precise drug design through iterative molecular SNÅPshots that help us design and predict which product candidates may demonstrate the highest potency, selectivity and tolerability in the clinic. We have initially leveraged our SNÅP approach to develop TYRA-300, TYRA-200 and TYRA-430: three clinical-stage, novel small molecules designed to overcome the toxicity and resistance liabilities of first generation pan-FGFR inhibitors.

Our FGFR3 Programs—TYRA-300 for Bladder Cancer and Skeletal Conditions 

Mutations in the protein receptor FGFR3 are a key driver in two indications with large market opportunities: bladder cancer and skeletal conditions. In bladder cancer, uncontrolled activation of FGFR3 on the cell surface stimulates cellular proliferation. In skeletal conditions, increased activity of FGFR3 expressed in growth plate chondrocytes (cartilage cells) results in excessive limitation of long bone growth.  

Our lead program, TYRA-300, was designed to be more selective for FGFR3 over FGFR1, FGFR2, and FGFR4 to minimize off-target side effects, providing potential clinical advantages over less selective first-generation compounds and potentially addressing key unmet needs across both bladder cancer and skeletal conditions.   	

TYRA-300 is to be evaluated in three Phase 2 studies: SURF301, for the treatment of metastatic urothelial carcinoma (mUC); SURF302, for the treatment of non-muscle invasive bladder cancer (NMIBC); and BEACH301, for the treatment of pediatric achondroplasia (ACH).    

SURF301 for mUC: This ongoing study is an international, multi-center, open label Phase 1/2 clinical trial that was designed to determine the optimal and maximum tolerated doses (MTD), and the recommended Phase 2 dose (RP2D) of TYRA-300, as well as to evaluate the preliminary antitumor activity of TYRA-300. In late October 2024, we reported interim data that in patients with FGFR3+ mUC who received doses ≥ 90 mg once daily (QD), 6 out of 11 (54.5%) patients achieved a confirmed
