TG received guidance from the FDA allowing submission of a single NDA for Marginal Zone Lymphoma (MZL) and Follicular Lymphoma indications

Completion of rolling submission for the MZL/FL NDA expected in 1H20

NEW YORK, NY, USA I January 16, 2020 I TG Therapeutics, Inc. (NASDAQ: TGTX), a biopharmaceutical company developing medicines for patients with B-cell mediated diseases, announced that the Company has initiated a rolling submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) requesting accelerated approval of umbralisib, the Company’s oral, once-daily, dual inhibitor of PI3K-delta and CK1-epsilon, as a treatment for patients with previously treated marginal zone lymphoma (MZL) and follicular lymphoma (FL). The Company has received guidance from the FDA that submission of a single NDA for both the MZL and FL indications is acceptable. Umbralisib has previously been granted both orphan drug designation and breakthrough therapy designation by the FDA for MZL. The Company expects to complete the NDA rolling submission in the first half of 2020.

Michael S. Weiss, Executive Chairman and Chief Executive Officer of TG Therapeutics stated, “We are extremely pleased to have initiated our first NDA submission for umbralisib and to have received guidance from the FDA to include both MZL and FL in a single NDA. This is an extremely important milestone for us, as it brings us one step closer to potentially offering a novel treatment option to patients with previously treated MZL and FL.” Mr. Weiss continued, “I want to thank the patients, their families and the research teams who participated in these important trials and helped advance umbralisib, and the TG team for working tirelessly to initiate this NDA submission. This is the beginning of an impactful 2020 as we look forward to topline Phase 3 data from both the UNITY-CLL trial and the ULTIMATE I & II trials in multiple sclerosis, as well as potential regulatory submissions based off these data.”

ABOUT THE UNITY-NHL PHASE 2b STUDY—MARGINAL ZONE LYMPHOMA AND FOLLICULAR LYMPHOMA COHORTS 

The UNITY- NHL trial is a multicenter, open-label Phase 2b trial.

The Marginal Zone Lymphoma (MZL) cohort was designed to evaluate the safety and efficacy of single agent umbralisib, in patients with MZL who have received at least one prior anti-CD20 regimen. The primary endpoint is overall response rate (ORR) as determined by central Independent Review Committee (IRC) assessment.

The Follicular Lymphoma (FL) cohort was designed to evaluate the safety and efficacy of single agent umbralisib in patients with FL who have received at least two prior lines of therapy, including an anti-CD20 regimen and an alkylating agent. The primary endpoint is overall response rate (ORR) as determined by Independent Review Committee (IRC) assessment.

ABOUT TG THERAPEUTICS, INC.

TG Therapeutics is a biopharmaceutical company focused on the acquisition, development and commercialization of novel treatments for B-cell malignancies and autoimmune diseases. Currently, the company is developing two therapies targeting hematological malignancies and autoimmune diseases. Ublituximab (TG-1101) is a novel, glycoengineered monoclonal antibody that targets a specific and unique epitope on the CD20 antigen found on mature B-lymphocytes. TG Therapeutics is also developing umbralisib (TGR-1202), an oral, once-daily dual inhibitor of PI3K-delta and CK1-epsilon, which may overcome certain tolerability issues associated with first generation PI3K-delta inhibitors. Both ublituximab and umbralisib, or the combination of which is referred to as “U2”, are in Phase 3 clinical development for patients with hematologic malignancies, with ublituximab also in Phase 3 clinical development for Multiple Sclerosis. Additionally, the Company has recently brought its anti-PD-L1 monoclonal antibody, TG-1501, its covalently-bound Bruton’s Tyrosine Kinase (BTK) inhibitor, TG-1701, as well as its anti-CD47/CD19 bispecific antibody, TG-1801, into Phase 1 development. TG Therapeutics is headquartered in New York City.
