TG Therapeutics Announces Exclusive Licensing Agreement With Ildong Pharmaceutical Co., Ltd. for Development and Commercialization of Ublituximab (TGTX-1101) in South Korea and Southeast Asia

Nov 15, 2012

NEW YORK, Nov. 15, 2012 (GLOBE NEWSWIRE) -- TG Therapeutics, Inc. (OTCBB:TGTX) today announced that it has entered into an exclusive licensing agreement with Ildong Pharmaceutical Co. Ltd. (Ildong) for the development and commercialization of the company's novel anti-CD20 antibody, Ublituximab (TGTX-1101) in South Korea and Southeast Asia.

Under the terms of the agreement, TG Therapeutics will receive an upfront payment of $2 Million in addition to sales based milestone and royalty payments in exchange for exclusive rights to develop and commercialize Ublituximab for all therapeutic indications in the territory.

Ublituximab is under development by TG Therapeutics for hematologic malignancies and other B-cell lymphoproliferative disorders, and is currently being evaluated in a North American Phase I/II clinical trial in patients with relapsed or refractory non-Hodgkin's lymphoma. 

"Having already demonstrated impressive clinical activity in patients with relapsed and refractory Chronic Lymphocytic Leukemia, Ublituximab has shown itself to be a promising treatment for patients with B-cell related disorders. We are excited to work with the experienced team at Ildong to expand the scope of development for Ublituximab," stated Michael S. Weiss, Chairman and Interim CEO of TG Therapeutics. 

"We are delighted to have added Ublituximab to our pipeline in biologics and it is a strategic fit for Ildong," said Jung-Chi Lee, Chairman & CEO of Ildong. "We believe Ublituximab, a next generation anti-CD20 therapy will strengthen our presence in oncology and auto-immune areas and look forward to working with TG Therapeutics in developing Ublituximab in South Korea and Southeast Asia."

MedCI LLC served as licensing advisor and provided assistance to TG Therapeutics with respect to this transaction.


Ublituximab is a novel, third generation chimeric monoclonal antibody targeting a unique epitope on the CD20 antigen found on B lymphocytes. Ublituximab has been bioengineered for enhanced biological activity with an increased ability to trigger an immune response, delivering superior ADCC effects to aid in B-cell depletion. Ublituximab has displayed high single agent activity in a Phase I/II clinical trial in patients with relapsed Chronic Lymphocytic Leukemia, and is being developed by TG Therapeutics in multiple oncology and autoimmune indications.

Ublituximab has been granted orphan status in Europe and in the USA for B-cell Chronic Lymphocytic Leukemia, and is currently being evaluated in a Phase I/II clinical trial in patients with non-Hodgkin's lymphoma relapsed or refractory to prior anti-CD20 therapy.
