Salarius Pharmaceuticals Adds Seattle Cancer Care Alliance and Oregon Health & Sciences as Clinical Sites for its Ongoing Trial of Seclidemstat as a Treatment for Ewing Sarcoma and FET-Rearranged Sarcomas
Clinical Trial Now Expands to Fifteen U.S. Trial Sites
HOUSTON, Aug. 04, 2022 (GLOBE NEWSWIRE) — Salarius Pharmaceuticals, Inc. (NASDAQ: SLRX), a clinical-stage biopharmaceutical company developing therapies for patients with cancer in need of new treatment options, announces the addition of four prestigious institutions to the open-label Phase 1/2 trial with seclidemstat in Ewing’s sarcoma and FET-rearranged sarcomas. The Seattle Cancer Care Alliance (SCCA) – which is comprised of the Fred Hutchinson Cancer Research Center, Seattle Children’s Hospital and University of Washington Medical Center – as well as Oregon Health & Sciences University in Portland are now supporting trial enrollment.
Seclidemstat is a novel oral, reversible, targeted LSD1 inhibitor that affects gene expression and is currently being studied in Phase 1/2 clinical studies for the treatment of solid and hematologic cancers where LSD1 is implicated in disease progression.
Clinical trial work at SCCA is being led by Lee Cranmer, M.D., Ph.D., FACP, Director of Sarcoma Medical Oncology, Associate Professor University of Washington School of Medicine and Associate Professor, Clinical Research Division Fred Hutchinson Cancer Research Center.
Enrollment at Oregon Health & Sciences University is being led by Lara E. Davis, M.D., Associate Professor of Medicine, Division of Hematology/Medical Oncology, School of Medicine, Co-Leader, Knight Cancer Institute Translational Oncology Program and Sarcoma Program Director.
“Salarius continues to advance the development of seclidemstat as a potential treatment for selected sarcomas and we believe that the addition of these prestigious organizations as clinical trial sites allows us to accelerate that development,” said David Arthur, chief executive officer of Salarius. “We expect to report interim data in the second half of this year and are hopeful that seclidemstat, either alone or in combination with standard chemotherapy, will have a positive impact on the lives of these patients.”
In addition to Seattle Cancer Care Alliance and Oregon Health & Sciences, clinical trial site locations include, Johns Hopkins All Children’s Hospital in St. Petersburg, FL; Children’s Hospital of Los Angeles in Los Angeles, CA; Moffitt Cancer Center in Tampa, FL; Dana-Farber Cancer Institute in Boston, MA; MD Anderson Cancer Center in Houston, TX; Nationwide Children’s Hospital in Columbus, OH; Memorial Sloan Kettering Cancer Center in New York City; and the Sarcoma Oncology Center in Santa Monica, CA; Virginia Cancer Specialists, Fairfax, Virginia; Cleveland Clinic, Cleveland, Ohio; Washington University, St. Louis, Missouri; Oncology Consultants, Houston, Texas and Fox Chase Cancer Center in Philadelphia PA.
About the Phase 1/2 Ewing’s and other FET-rearranged sarcomas trial
The Phase 1/2 trial currently is in its dose-expansion stage, which includes three patient arms. The first arm is enrolling up to 30 patients with Ewing’s sarcoma, a rare and deadly pediatric bone cancer, and will investigate seclidemstat in combination with topotecan and cyclophosphamide, a commonly used second- and third-line chemotherapy regimen. Salarius believes data released during ASCO 2021 demonstrated synergy in an Ewing’s sarcoma cell line when seclidemstat was used in combination with these agents. Salarius also believes this treatment combination and its use as a second- and third-line therapy could greatly expand the addressable patient population for seclidemstat and improve outcomes by allowing physicians to introduce seclidemstat earlier in the Ewing’s sarcoma continuum of care.
The trial’s second patient arm is investigating seclidemstat as a single agent in up to 15 patients with myxoid liposarcoma. The third patient arm is investigating seclidemstat as a single agent in up to 15 patients with select sarcomas that share a similar biology to Ewing’s sarcoma, also referred to as FET-rearranged or Ewing’s-related sarcomas. In data released at ASCO 2021, a subset of patients with advanced FET-rearranged sarcomas treated with single-agent seclidemstat resulted in stable disease and prolonged time to progression, which Salarius believes suggests disease control, a clinically relevant endpoint for soft tissue sarcomas.
All three patient arms are designed to evaluate safety and efficacy in patients with advanced disease. Salarius expects to report interim data updates in the second half of 2022.
