- Clinical Trial Progress: TG Therapeutics reported that the injectable version of Briumvi demonstrated over 60% bioavailability in early trials, strongly supporting the quarterly subcutaneous dosing regimen currently being tested in late-stage trials, which could significantly enhance market opportunities.
- Safety Assessment: The company noted that the injectable ublituximab was generally well tolerated, with treatment-emergent adverse events aligning with expectations for IV Briumvi, indicating that the new formulation's safety profile is comparable to existing treatments.
- Market Potential: If approved, the self-administered at-home option would drastically reduce the number of annual injections, potentially doubling Briumvi's addressable market opportunity and further solidifying its position in multiple sclerosis treatment.
- Future Outlook: CEO Michael Weiss emphasized that the current trial data bolsters confidence in achieving the primary endpoint for the quarterly subcutaneous dosing regimen, with plans to report Phase 3 trial data later this year or early next year, aiming for potential approval by 2028.
