Sep 15, 2014
Overall Response Rate (ORR) to be the Primary Endpoint to Support Accelerated Approval with Progression-Free Survival (PFS) to Support Full Approval
Safety and Efficacy Data from Over 30 CLL Patients from the On-going Phase 2 Trial of the Combination of TG-1101 plus ibrutinib Anticipated to be Presented at ASH 2014
Full details of the Phase 3 clinical trial will be released at the launch of the study, which is expected to occur before the end of the year. In this randomized controlled trial, patients will receive either TG-1101 plus ibrutinib or ibrutinib alone. The trial will enroll approximately 330 patients, with approximately the first two-thirds of the patients included in the ORR assessment. As per the SPA, the Company plans to use the ORR data from the trial as the basis for submission of a Biologics License Application (BLA) for accelerated approval for TG-1101. All patients will then be followed for PFS assessment, which is designed to support full approval.
Additionally, the Company reported that enrollment into the CLL cohort of its ongoing combination Phase 2 study of TG-1101 plus ibrutinib is now closed. The Company expects it will have over 30 CLL patients evaluable for safety and efficacy available for presentation at the Annual Meeting of the

ABOUT TG THERAPEUTICS, INC.
TG Therapeutics is an innovative, clinical-stage biopharmaceutical company focused on the acquisition, development and commercialization of novel treatments for cancer 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.
