Item 8.01 Other Events.

On October 18, 2022, Salarius Pharmaceuticals announced that per protocol design, it voluntarily paused new patient enrollment in the Company’s Phase 1/2 trial of seclidemstat as a treatment for Ewing sarcoma and FET-rearranged sarcomas. At the time, Salarius also announced that the company’s independent Safety Review Committee for the clinical trial determined that patients currently receiving seclidemstat treatment could continue treatment after consulting with their physician.

During a conference call with the US Food and Drug Administration (FDA) on Tuesday, November 1, 2022, the FDA informed Salarius that the agency agreed with the voluntary enrollment pause and, as an administrative action, the FDA provided verbal notification that the Ewing sarcoma and FET-rearranged sarcoma trial was on partial clinical hold. While on partial clinical hold, FDA informed Salarius that the pause in patient enrollment shall remain in place and patients currently receiving seclidemstat treatment may continue treatment after consulting with their physician. FDA’s clinical hold procedures provide Salarius with an administrative process to work with the FDA to analyze the available data, adjust clinical protocols, and make other changes that may be needed in order to restart patient enrollment.
