Item 7.01.    Regulation FD Disclosure.

 

On April 19, 2018, Onconova Therapeutics, Inc. (“Onconova” or the “Company”) issued a press release relating to ON 123300 as described in Item 8.01 below. A copy of the press release is attached hereto as Exhibit 99.1 and incorporated herein by reference. The information disclosed under this Item 7.01 (including Exhibit 99.1) is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

 

Item 8.01.    Other Events.

 

On April 19, 2018, the Company issued a press release announcing an advance in pre-clinical development and the presentation of new data for investigational ON 123300, a novel dual inhibitor of CDK4/6 + ARK 5 with potential application across a variety of cancers.

 

CDK inhibitors have emerged as promising and potentially targeted large market cancer therapies. ON 123300 has the potential to overcome many of the limitations of current generation CDK4/6 inhibitors. Onconova believes that ON 123300 may act as a single agent, due to the unique targeting of ARK5, as well as CDK 4 and 6, making it potentially suitable for indications that may not be responsive to the current generation of CDK4/6 inhibitors.

 

Onconova and HanX Biopharmaceuticals, the Company’s Greater China collaboration partner for ON 123300, recently completed the pre-Investigational New Drug (“pre-IND”) consultation with the U.S. Food and Drug Administration (“FDA”). These discussions provided guidance for the manufacturing of ON 123300 and the pre-clinical development plan for the submission of an Investigational New Drug (“IND”) application.

 

The data from preclinical studies demonstrates that there is a differential metabolism of ON 123300 in male versus female rodents. As a result, the drug exposure is almost 2-3 fold higher in female rats. Based upon preclinical animal liver microsome studies, this differential effect appears to be limited to rodents, and is not observed in preclinical studies with human liver microsomes. Based on the metabolism data from other species, relevant species have been selected along with the dosing strategy to be implemented in GLP toxicological studies to be conducted by HanX. As a part of the pre-clinical development program, Onconova and HanX announced a collaborative program in December 2017, wherein the remaining IND enabling studies will be funded by and conducted by HanX.

 

Onconova previously reported that ON 123300 was found to be as active as Palbociclib (Pfizer’s Ibrance®) in a preclinical Rb + ve xenograft model. Moreover, the molecule may have the potential advantage of reduced neutropenia when compared to Palbociclib based upon this model.
