TG Therapeutics, Inc. Announces Updated Results from the Ongoing Phase 2 Study of Ublituximab (TG-1101) in Patients with Multiple Sclerosis at the Third Annual ACTRIMS Forum 2018
Feb 02, 2018
100% reduction of T1 Gd-enhancing lesions at week 24 (n=38)
99% median B-cell depletion was observed at week 4 and maintained at week 24 (n=40)
TG-1101 was well tolerated across all patients including those receiving 1 hour infusions at the Phase 3 dose
This Phase 2 trial is a 52-week randomized, placebo controlled, multi-center study evaluating the safety and efficacy of ublituximab at accelerated infusion times as fast as one hour. Today's poster includes 6 month data from the first 40 patients (of 48 enrolled, 8 too early to evaluate) with RMS that were treated with ublituximab across five dosing cohorts.
Poster Presentation Title: 6 Month Results of a Phase 2a Multicenter Study of Ublituximab, a Novel Glycoengineered Anti-CD20 Monoclonal Antibody, in Relapsing Multiple Sclerosis
99% median B-cell depletion was observed at week 4 and maintained at week 24 (6 months) (n=40)
• Ublituximab completely eliminated all (100%) of T1 Gd-enhancing lesions at week 24 (n=38) (p=0.0005)
• 97.5% of subjects (39/40) were relapse free at week 24
- One confirmed relapse was reported, in Cohort 1. The patient was initially randomized to the placebo arm. The relapse occurred 12 days after the patients' first infusion of 150mg of TG-1101. The patient remains on study and has received the second and third infusions of TG-1101 and to date has remained relapse free.
• Mean EDSS improvement from baseline of 0.3 with 78% of subjects showing improved or stable EDSS
• Ublituximab was well tolerated across all patients including those receiving rapid infusions, as low as a one hour for the 450mg Phase 3 dose
These data presentations support the international Phase 3 ULTIMATE program evaluating ublituximab for the treatment of relapsing form of Multiple Sclerosis (RMS). The Phase 3 trials, entitled ULTIMATE I and ULTIMATE II, are being conducted under Special Protocol Assessment (SPA) agreement with the

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 orally available PI3K
delta inhibitor. The delta isoform of PI3K is strongly expressed in cells of hematopoietic origin and is believed to be important in the proliferation and survival of B‐lymphocytes. 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 into Phase 1 development and aims to bring additional pipeline assets into the clinic in the future. TG Therapeutics is headquartered in New York City.
Statements included in this press release, particularly those with respect to anticipating the benefit of the early data seen in the Phase 2 MS trial and anticipating the timing of our MS Phase 3 program may be forward-looking statements that involve a number of risks and uncertainties. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Among the factors that could cause our actual results to differ materially are the following: our ability to successfully and cost-effectively complete the MS Phase 2 and Phase 3 trials; the risk that early clinical results that supported our decision to move forward will not be reproduced in additional patients in expansion cohorts or in the MS Phase 3 program; the risk that data included in any poster presentation will not be reproduced in subsequent data presentations; the risk that the clinical results from the MS Phase 3 program, will not be positive and/or will not support regulatory approval of ublituximab for MS; the risk that ublituximab will not have a differentiated profile from the other drugs in the class and that early signs of best-in-class attributes will not be supported by future results; the risk that trials will take longer to enroll than expected; our ability to achieve the milestones we project over the next year; our ability to manage our cash in line with our projections, and other risk factors identified from time to time in our reports filed with the Securities and Exchange Commission. Any forward-looking statements set forth in this press release speak only as of the date of this press release. We do not undertake to update any of these forward-looking statements to reflect events or circumstances that occur after the date hereof.
