Market Impact & Outlook
| Metric | Value |
|---|---|
| U.S. R/R MCL Patient Pool | ~3,500 patients annually |
| Current Standard | BTK inhibitors (ibrutinib, acalabrutinib); limited options post‑BTK failure |
| BCL2 Inhibitor Market | $2.5 billion globally (2024); expanding in hematology |
| Pricing | Expected $150,000‑200,000/year (aligns with oral oncolytics) |
| Peak Sales Forecast | $300‑450 million (U.S. peak) by 2031 |
| Competitive Landscape: AbbVie/Roche’s Venclexta approved in CLL/SLL but not MCL; Sotoclax could be first BCL2 inhibitor in MCL |
