Salarius Pharmaceuticals Completes SP-3164 Pre-Investigational New Drug Meeting Process with the U.S. Food and Drug Administration

Salarius planning for SP-3164 IND Application Submission in 2023


HOUSTON, May 11, 2022 (GLOBE NEWSWIRE) -- Salarius Pharmaceuticals, Inc. (Nasdaq: SLRX), a clinical-stage biopharmaceutical company developing potential new medicines for patients with sarcomas, pediatric cancers, hematologic cancers and other cancers, today announced the successful completion of its pre-IND (Investigational New Drug) meeting process with the U.S. Food and Drug Administration (FDA) for SP-3164. SP-3164 is a next-generation targeted protein degrader that induces selective elimination of cancer-causing proteins. Salarius is developing SP-3164 as a potential treatment for hematological cancers and solid tumors.

Through the pre-IND meeting process, Salarius obtained valuable FDA input that provided clarity on preclinical, clinical, and other regulatory matters for preparing and submitting an IND. Salarius is planning to submit an IND in 2023 and, upon receiving IND activation from the FDA, initiate the first clinical trial that same year.

“SP-3164 is a unique opportunity for Salarius to enter the fast-growing field of targeted protein degradation, which offers potential to develop medicines targeting cancer-promoting proteins that have historically been considered undruggable,” said David Arthur, CEO of Salarius Pharmaceuticals. “The successful completion of the pre-IND meeting process supports our plan to initiate the first clinical trial with SP-3164 in 2023. We look forward to having multiple clinical programs across two important drug classes: protein degradation with SP-3164 and protein inhibition with seclidemstat.”

About SP-3164

SP-3164 is a next-generation, deuterium-stabilized (S)-enantiomer of avadomide (CC-122). Avadomide is one of the most extensively studied molecular glues, a class of targeted protein degraders, and data from various clinical trials in hematological cancers and solid tumors has shown potential efficacy and tolerability. SP-3164 is a patent-protected new molecular entity derived from avadomide with the potential for increased efficacy and improved safety, based upon preclinical results to date.
