TGTX Thrives on Briumvi Sales Uptake

Briumvi, which remains a key contributor to the company’s revenues, has witnessed strong demand in the first half of 2026, and management expects the trend to continue during the second half as well.

Briumvi generated sales of $437.1 million in the first six months of 2026, up around 69% year over year. Reflecting the strong demand for the drug, TG Therapeutics raised its total revenue guidance. The company now expects worldwide total revenues of around $950 million in 2026 compared with the previous expectation of around $925 million.

Importantly, it now expects net product revenues of $890-$905 million from Briumvi sales in the United States in 2026, up from the previous expectation of $885-$900 million.

TGTX’s Ongoing Development Activities With Briumvi

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

In July 2026, TG Therapeutics initiated a phase II study evaluating Briumvi for the treatment of adult patients with treatment-resistant schizophrenia. Per management, the study is expected to help determine whether B-cell depletion with Briumvi can improve symptoms in adult patients with treatment-resistant schizophrenia.

The company also recently initiated a phase II study to evaluate the efficacy and safety of Briumvi in maintaining clinical response in patients with myasthenia gravis who initially respond to treatment with the FcRn inhibitor, Vyvgart (efgartigimod).

Meanwhile, TG Therapeutics is developing a self-administered subcutaneous formulation of Briumvi for treating RMS in a pivotal phase III study. Top-line data from this study are expected to be announced by the end of 2026 or the first quarter of 2027.

If successfully developed, the Briumvi SC formulation may eventually be available as a quick injection rather than a lengthy IV infusion, which could make treatment more convenient for patients.

The successful development of Briumvi for additional indications could help TG Therapeutics expand its addressable patient population and drive revenue growth. Positive data readouts from ongoing clinical studies could also serve as potential catalysts for the stock.
