TGTX's Single-Dose Briumvi Hits Bioequivalence Goal in MS Study

Read MoreHide Full Article

Key Takeaways

  • TGTX's ENHANCE Study met its primary endpoint for a single 600 mg Briumvi infusion in relapsing MS patients.
  • Briumvi showed bioequivalent exposure over 16 weeks, with no new safety signals reported.
  • TGTX plans an FDA filing in H2 2026 to eliminate Briumvi's day 15 infusion dose.

TG Therapeutics (TGTX - Free Report) has announced positive top-line data from the late-stage ENHANCE study, which evaluated a consolidated single-infusion regimen of its sole marketed drug, Briumvi (ublituximab-xiiy), in adult patients with relapsing forms of multiple sclerosis (MS).

The study achieved its primary endpoint, demonstrating that a single 600 mg infusion of Briumvi on day 1 in patients with relapsing forms of MS achieved bioequivalent drug exposure over 16 weeks compared with the currently approved standard Briumvi initiation regimen that requires two initial doses two weeks apart. Secondary endpoints were consistent with previously conducted clinical studies on the drug, with no new safety signals observed.

We remind investors that the drug is already approved to treat adult patients with relapsing forms of MS, with an initial dosing regimen that requires the first infusion at a 150 mg dose on day one, followed by a second infusion of 450 mg on day 15. Thereafter, subsequent infusions of 450 mg are administered every 24 weeks.

Data from the ENHANCE study support the potential elimination of the day 15 dose. Based on the above study results, TGTX intends to file a supplemental biologics license application with the FDA in the second half of 2026. If approved, Briumvi would become the first intravenously (IV) administered anti-CD20 therapy initiated with a single infusion.

Briumvi — A Key Revenue Driver for TGTX

TG Therapeutics’ top line primarily comprises product sales from Briumvi. In the first quarter of 2026, the company recorded $201.3 million from Briumvi sales, up 68.2% year over year. Briumvi has been witnessing strong demand in recent quarters, and this trend is expected to continue as 2026 progresses.

Several additional studies on Briumvi targeting other autoimmune diseases are currently ongoing.

TG Therapeutics completed enrollment in the phase III study in April, evaluating the subcutaneous formulation of Briumvi for the treatment of relapsing forms of MS. Top-line data from the study are expected by the end of 2026 or the first quarter of 2027.

The company is also developing Briumvi for additional autoimmune indications, including a potentially registration-directed study evaluating Briumvi in patients with myasthenia gravis.

The successful development of Briumvi for additional indications will help TG Therapeutics address a broader patient population and diversify revenue growth.
