TG Therapeutics, Inc. Announces Updated Results from the Ongoing
Phase 2 Study of Ublituximab (TG-1101) in Patients with Multiple
Sclerosis at the American Academy of Neurology 70th Annual
Data on now up to 48 patients through 24 weeks confirms previously
reported positive results
York, NY, (April 24, 2018)
TG Therapeutics, Inc. (NASDAQ: TGTX), today announced updated
results from the Phase 2 multicenter trial of ublituximab
(TG-1101), the Company's novel glycoengineered anti-CD20
monoclonal antibody, in relapsing forms of Multiple Sclerosis
(RMS). The data is being presented today during Poster Session P3,
from 5:30 PM 7:00 PM PT, at the American Academy of
Neurology 70th Annual Meeting in
Los Angeles, California.
S. Weiss, the Company's Executive Chairman and Chief
Executive Officer, stated, We are extremely pleased by the
data presented today which now includes a total of 48 patients
across six dosing cohorts for a period of up to 24 weeks. With more
patients now through 24 weeks of follow-up, the data continue to
confirm the efficacy of ublituximab with sustained B-cell
depletion, 100% reduction in T1 Gd-enhancing lesions, and most
importantly, an annualized relapse rate (ARR) that remains below
the ARR observed with ocrelizumab, the only approved anti-CD20
monoclonal antibody for MS, in its similarly sized Phase 2 study.
ARR is the primary endpoint of our Phase 3 trial, which was modeled
and powered based on the results from the ocrelizumab pivotal
trial. We are excited by the emerging clinical profile of
ublituximab that appears to have comparable to better activity than
ocrelizumab, with a manageable safety profile and the convenience
of a one hour infusion. Mr. Weiss continued We look
forward to presenting additional data from this Phase 2 trial
including 48 week data on up to 48 patients at major medical
meetings later this year.
This Phase 2 trial is a 48-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 (24 week) data from 48
patients with relapsing forms of multiple sclerosis (RMS) that were
treated with ublituximab across six dosing cohorts.
Results At 6 Months From A Phase 2 Multicenter Study Of
Ublituximab, A Novel Glycoengineered Anti-CD20 Monoclonal Antibody
(mAb), In Patients With Relapsing Forms Of Multiple Sclerosis
(RMS), Demonstrates Complete Elimination Of Gd-Enhancing Lesions
Relapse Rate (ARR) of 0.05 was observed at Week 24
depletion was observed at week 4 and maintained at Week 24
completely eliminated all (100%) of T1 Gd-enhancing lesions at Week
were relapse free at Week 24
relapse was reported, in Cohort 1. The patient was initially
randomized to the placebo arm. The relapse occurred shortly (12
days) after crossover to active treatment of 150mg of ublituximab.
The patient remains on study and has received the second and third
infusions of ublituximab and to date has remained relapse
showed improved or stable EDSS with a mean EDSS improvement from
well tolerated across all patients including those receiving rapid
infusions, as low as a one hour for the 450mg Phase 3
These data presentations support the international Phase 3 ULTIMATE
program evaluating ublituximab for the treatment of relapsing forms
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 U.S. Food and Drug
Administration (FDA) and are being led by Lawrence Steinman, MD, of
Stanford University. The ULTIMATE trials are currently enrolling
and complete enrollment is expected in the first quarter of

ABOUT TG THERAPEUTICS, INC.
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
Cautionary Statement
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
