-
Potential for Market Expansion
The CEO stated that a self-administered, at-home, quarterly anti-CD20 therapy could nearly double the addressable market opportunity for the BRIUMVI franchise.

Analysis
TG Therapeutics announced positive Phase 1 clinical trial results for a subcutaneous formulation of BRIUMVI, its approved multiple sclerosis drug. This data is crucial as it supports the ongoing Phase 3 trial for a more convenient, self-administered, at-home quarterly dosing regimen. The company's CEO highlighted that a subcutaneous option could nearly double the addressable market for the BRIUMVI franchise, representing a significant commercial opportunity. The positive safety and pharmacokinetic/pharmacodynamic data de-risks the Phase 3 program, with topline results expected in late 2026 or early 2027.
