David Arthur, President and CEO of Salarius Pharmaceuticals, stated, "We believe this strategic merger and Nasdaq listing establishes a foundation for future growth. The enhanced visibility and exposure to institutional investors will allow Salarius to showcase the potential of our lead asset, Seclidemstat, and showcase our clinical pipeline. We look forward to sharing important updates with our investors as we advance our clinical programs."

Salarius’ lead compound, Seclidemstat, targets the epigenetic dysregulation underlying Ewing sarcoma, a devastating pediatric, adolescent, and young adult bone and soft-tissue cancer for which no approved targeted therapies are currently available. Seclidemstat is a differentiated, reversible inhibitor of lysine-specific demethylase 1, or LSD1, which is a widely studied epigenetic enzyme and a validated drug target for clinical development. Salarius is currently enrolling refractory and relapsed Ewing sarcoma patients in an open-label Phase 1 dose escalation/dose expansion study, with potential early cohort data readouts in 2020. Salarius is also conducting a Phase 1 clinical study of Seclidemstat in patients with advanced solid tumors including, but not limited to, prostate, breast, and ovarian cancers.
