Will Bezuclastinib’s Broad APEX and SUMMIT Success Change Cogent Biosciences' (COGT) Narrative?

• Cogent Biosciences recently reported positive registration-directed APEX Part 2 results for bezuclastinib in advanced systemic mastocytosis and complete SUMMIT data in nonadvanced disease, showing high response rates and significant reductions in key disease markers with a manageable safety profile.
• Together with earlier PEAK data in GIST, these three successful pivotal trials position bezuclastinib as a potential foundation therapy across multiple KIT-driven mast cell and tumor indications.
• With these data in hand, we'll now look at how bezuclastinib’s broad efficacy across mastocytosis subtypes shapes Cogent’s investment narrative.

What Is Cogent Biosciences' Investment Narrative?

To own Cogent Biosciences, you have to believe bezuclastinib can convert three positive pivotal trials into durable, commercial franchises in systemic mastocytosis and KIT-driven tumors before the cash burn becomes a problem. The new APEX and SUMMIT Part 2 data strengthen the core thesis: a single asset with broad activity across advanced and nonadvanced mastocytosis, backed by objective biomarker reductions and a manageable safety profile. Near term, the likely key catalysts now cluster around the planned AdvSM NDA filing in the first half of 2026, further data presentations, and any clarity on regulatory paths in NonAdvSM and GIST. On the risk side, Cogent still has no revenue, ongoing heavy losses and a recent US$300,000,000 raise, so future dilution and regulatory setbacks remain front of mind, especially after such a very large share price run.

However, there is one risk around future funding and approvals that investors should not overlook. Our valuation report here indicates Cogent Biosciences may be overvalued.
