NEW YORK, April 13, 2016 (GLOBE NEWSWIRE) -- TG Therapeutics, Inc. (Nasdaq:TGTX) today announced that the United States Patent and Trademark Office (USPTO) has issued a patent for the composition of matter of TG-1101, the Company’s novel, glycoengineered monoclonal antibody. The patent, U.S. Patent No. 9,234,045 specifically covers the composition of TG-1101, and its use for treating various forms of CD20 expressing leukemia and lymphoma, including chronic lymphocytic leukemia (CLL) and various types of non-Hodgkin’s lymphoma, including follicular lymphoma (FL), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), and diffuse large B-cell lymphoma (DLBCL).
The patent was issued to LFB SA and is exclusively licensed to TG Therapeutics pursuant to the Company’s existing license agreement with LFB SA. The issuance affords patent protection for TG-1101 in the US through July of 2029, exclusive of additional patent term extensions also available. TG-1101 is currently being studied in two Phase 3 clinical trials in patients with CLL, with additional registration directed trials in NHL expected to commence in 2016.
“We are excited to announce the issuance of the first U.S. patent for TG-1101 which affords protection through 2029. With composition of matter patents now in place for both TG-1101 and TGR-1202, and an additional later-filed patent application on the combination of TG-1101 and TGR-1202, we believe we have established a very strong intellectual property position for the two components of our proprietary ‘TG-1303’ regimen that provides a very attractive exclusivity period without the risk of generic competition for many years to come,” stated Michael S. Weiss, the Company's Executive Chairman and Interim CEO. Mr. Weiss continued, “We remain focused on continuing to strengthen our intellectual property position through the issuance of additional patents for both TG-1101 and TGR-1202 individually as well as in combination here in the US and abroad.”
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. TG-1101 (ublituximab) 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 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 TG-1101 and TGR-1202 are in clinical development for patients with hematologic malignancies. The Company also has a pre-clinical program to develop IRAK4 inhibitors, as well as an antibody research program to develop anti-PD-L1 and anti-GITR antibodies. TG Therapeutics is headquartered in New York City.
Some of the statements included in this press release, particularly those with respect to anticipating future clinical trials, the timing of commencing or completing such trials and possible success of those trials and business prospects for TG-1101, TGR-1202, TG-1303, the IRAK4 inhibitor program, and the anti-PD-L1 and anti-GITR antibodies 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 pre-clinical and clinical trials for TG-1101, TGR-1202, TG-1303, the IRAK4 inhibitor program and the anti-PD-L1 and anti-GITR antibodies; the risk that early pre-clinical and clinical results that supported our decision to move forward with TG-1101, TGR-1202, TG-1303, the IRAK4 inhibitor program and the anti-PD-L1 and anti-GITR antibodies will not be reproduced in additional patients or in future studies; the risk that trends observed which underlie certain assumptions of future performance of TGR-1202 and TG-1303 will not continue, the risk that TGR-1202 or TG-1303 will not produce satisfactory safety and efficacy results to warrant further development following the completion of the current Phase 1 studies; the risk that the combination of TG-1303, will not prove to be a safe and efficacious backbone for triple and quad combination therapies; the risk that the data (both safety and efficacy) from future clinical trials will not coincide with the data produced from prior pre-clinical and clinical trials; 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.
