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: (i) TG-1101 (ublituximab), a novel, glycoengineered monoclonal antibody that targets a specific and unique epitope on the CD20 antigen found on mature B-lymphocytes; and (ii) TGR-1202, an orally available PI3K delta inhibitor for various hematologic malignancies.

Throughout the Class Period, Defendants made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business and operations.  Specifically,  Defendants made false and/or misleading statements and/or omitted material information concerning the GENUINE Phase III trial, assuring investors it was a “best-in-class treatment” that would be “successful” and “offer patients a novel chemo-free treatment option.”  As a result of the foregoing, the Company’s statements were materially false and misleading at all relevant times.

On September 17, 2015, the Company announced that it had reached an agreement with the U.S. Food and Drug Administration (“FDA”) regarding a Special Protocol Assessment (“SPA”) on the design of a Phase III clinical trial for its proprietary combination of TG-1101 (ublituximab), its glycoengineered anti-CD20 monoclonal antibody, plus TGR-1202, the Company’s once-daily PI3K-delta inhibitor, for the treatment of Chronic Lymphocytic Leukemia (“CLL”). The Phase III clinical trial is referred to by the Company as “GENUINE.”

The purpose of the Phase III GENUINE trial was to show that TG-1101, in combination with Imbruvica (the trade name for an ibrutinib-based small molecule drug used to treat B cell cancers), could show an improvement in overall response rate (“ORR”) and progression-free survival (“PFS”) in 330 previously-treated patient with certain cancer cell mutations.

On October 13, 2016, TG Therapeutics announced that the Company had filed an “amended protocol for its GENUINE Phase III trial,” which entirely abandoned Part II of the Phase III GENUINE study designed to measure the combination’s effect on progression-free survival, thereby annulling the SPA with the FDA. Accordingly, the study’s sole primary endpoint was reduced to only overall response rate (ORR), as contemplated in Part I of the study, and the target enrollment was reduced to only 120 patients. As a result of cutting enrollment by more than half, the Company stated it could be another two years to reach 330 patients – the number needed to have sufficient powering to show a PFS benefit.

According to analysts, excluding patients who have already taken Imbruvica “is an obvious barrier to enrollment” and significantly increases the likelihood that the FDA will not approve the combination treatment.

On this news, TG Therapeutics’ share price fell $2.24, or 27%, to close at $6.01 on October 17, 2016.
