Briumvi Sales Performance
Preliminary net product revenues from Briumvi sales were $103.6 million in the fourth quarter and $310 million for the full year 2024.

A key development is the planned pivotal program for a self-administered subcutaneous formulation of Briumvi for treating patients with RMS, expected to begin in 2025. This new formulation aims to offer a more convenient dosing frequency of at least every other month.
The FDA has cleared the investigational new drug application (IND) for TG Therapeutics’ pipeline candidate, azercabtagene zapreleucel (azer-cel), for the treatment of progressive forms of multiple sclerosis (search) (MS). Enrollment of participants in the phase I study on azer-cel in progressive MS is anticipated to begin in 2025.
Management Commentary
Michael S. Weiss, Chairman and Chief Executive Officer of TG Therapeutics, stated, “2024 was a great year for TG, and we are excited to share preliminary fourth quarter and year end U.S. BRIUMVI net product revenue which far exceeded our initial expectations. We believe BRIUMVI is well positioned to continue to grow and provide value to patients and physicians.”
Weiss added, “On the development front we were excited to provide an update on our subcutaneous BRIUMVI work, which should allow us to commence a pivotal program in 2025 evaluating a self-administered subcutaneous product with an expected dosing frequency of least every other month, a product profile we believe will be attractive to patients and healthcare providers. In 2025 we also plan to launch pivotal trials aimed at further optimizing intravenous BRUIMVI for patients with RMS, continuing to maintain what we believe is a best-in-class profile. We also look forward to evaluating BRIUMVI in other indications outside of MS, and enrolling patients with progressive MS into a Phase 1 trial of our allogeneic CD19-directed CAR-T, azer-cel.”
