Material Event - Form 8-K

Item 8.01 Other Events.

On January 27, 2022, TG Therapeutics, Inc. (the "Company") participated in a webcast fireside chat during the B. Riley Securities' 2022 Virtual Oncology Investor Conference.During the webcast, Michael S. Weiss, Chief Executive Officer of the Company, shared a data and regulatory update. Mr. Weiss noted that the Company was nearing completion of a submission to the U.S. Food and Drug Administration (FDA) of updated Overall Survival (OS) analyses from the UNITY-CLL Phase 3 study evaluating the investigational U2 combination (UKONIQ^® (umbralisib) and ublituximab) compared to the control arm of obinutuzumab plus chlorambucil and that the FDA imposed a partial clinical hold on select studies of U2 and its components for chronic lymphocytic leukemia (CLL) and non-Hodgkin's lymphoma (NHL).

​

With regard to the data update, Mr. Weiss noted that the updated OS results from the UNITY-CLL study, showed an improvement from the preliminary data originally shared with the FDA, and previously disclosed on November 30, 2021, which was at that time an OS hazard ratio of 1.23 and when censoring for COVID-19 related deaths a hazard ratio of 1.04. An OS hazard ratio above 1.00 implies potential risk that the investigational therapy is causing harm and below 1.00 implies the possibility the drug is improving survival. The UNITY-CLL study was not powered for OS. Neither the original preliminary results nor the updated preliminary results were statistically significant, and the results are expected to change over time as more events occur. The original preliminary OS Hazard Ratio and the updated information discussed today were as of the same data cutoff date of September 2021.

​

With regard to the partial clinical hold, Mr. Weiss noted that no new patients may be enrolled to the select CLL/NHL studies identified by FDA, however patients on these studies who are deriving clinical benefit can continue on therapy once they have been reconsented. Mr. Weiss also noted that the partial clinical hold was not based on any new information provided by the Company to the FDA but appears to be based on the same data and concerns that gave rise to the previously announced Oncologic Drug Advisory Committee (ODAC) meeting, which is set to take place in the March/April 2022 timeframe. Most studies included in the partial clinical hold were previously closed to new enrollment or were on Company administrative hold to new enrollment. The Company does not expect to provide an update on the partial clinical hold prior to the ODAC meeting.

Forward-looking Statement

​

This 8-K contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, including statements relating to the interim overall survival analyses from the UNITY-CLL study, and the partial clinical hold that the FDA placed on select studies of the U2 regimen, including the ublituximab and UKONIQ^® (umbralisib) monotherapy arms of those studies. In addition to the risk factors identified from time to time in our reports filed with the U.S. Securities and Exchange Commission, factors that could cause our actual results to differ materially include the following: the risk that the FDA disagrees with the updated overall survival analysis from the UNITY-CLL study referenced in this 8-K; the risk that the overall survival analysis from the UNITY-CLL study, which is interim and statistically underpowered, changes over time in favor of the control arm as patients are followed for a longer period of time;  and the risk that FDA may not remove the partial clinical holds on studies evaluating the U2 combination, including the ublituximab and UKONIQ monotherapy arms of those studies.

​

Further discussion about these and other risks and uncertainties can be found in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as updated by our subsequent Quarterly Reports on Form 10-Q, and in our other filings with the U.S. Securities and Exchange Commission. Any forward-looking statements set forth in this 8-K speak only as of the date of this 8-K. We do not undertake to update any of these forward-looking statements to reflect events or circumstances that occur after the date hereof.
