Salarius Pharmaceuticals Receives First Installment of $1.7 Million in Payments from the Cancer Prevention and Research Institute of Texas

HOUSTON, Dec. 10, 2020 (GLOBE NEWSWIRE) -- . (Nasdaq: SLRX), a clinical-stage biopharmaceutical company developing potential new medicines for patients with pediatric cancers, solid tumors, and other cancers, today announced the receipt of a $0.8 million payment as part of an expected $1.7 million in payments under its contract with the Cancer Prevention and Research Institute of Texas (CPRIT). The payments are part of an original non-dilutive grant of up to $18.7 million awarded in 2016 to support Salarius’ operations and development of its lead drug candidate, seclidemstat, for the treatment of Ewing sarcoma and other cancers. Seclidemstat is a reversible LSD1 inhibitor being studied in two clinical trials — one trial in relapsed/refractory Ewing sarcoma, a rare and deadly pediatric bone cancer, and a second trial in advanced solid tumors (AST).

With the latest disbursement of CPRIT funds and the $6.2 million gross proceeds from a public offering completed in August 2020, Salarius believes it is well-capitalized to advance the seclidemstat clinical programs through several near-term, value-creating milestones with anticipated announcements beginning in late-2020 and continuing into the second half of 2021. These milestones include establishing maximum tolerated dose (MTD) in its Ewing sarcoma trial, releasing early safety and clinical data from both clinical trials, advancing into the dose-expansion phase of the Ewing sarcoma trial in early 2021, as well as expanding the same trial to include additional select sarcomas that share a similar biology to Ewing sarcoma, also known as Ewing-related sarcomas.

“The non-dilutive financial support Salarius has received from CPRIT since 2016 has been instrumental to our success in advancing the development of seclidemstat,” stated David Arthur, President and CEO of Salarius. “Since the original CPRIT grant, Salarius has received several special designations from the FDA to expedite drug development and we launched our clinical trials in Ewing sarcoma and Advanced Solid Tumors. Looking ahead, we expect to establish maximum tolerated dose in the Ewing sarcoma clinical trial and, as planned, advance to the dose-expansion phase of the study in the first quarter of 2021. This is an important milestone as it allows us to establish the recommended dosing regimen and begin treating a broader group of patients with Ewing and Ewing-related sarcomas.”

Founded in 2007 with a $3 billion bond issue and recently extended with an additional $3 billion bond issue, CPRIT funds cancer research and prevention services in Texas. Salarius was awarded a product development research grant in May 2016 for the development of seclidemstat and the disbursements are based upon Salarius’ achievement of specific goals and objectives. This $1.7 million in payments will bring the total disbursement from CPRIT to $11.3 million. Under the grant agreement, Salarius must provide matching funds equal to 50 percent of the CPRIT funding and make a good faith effort to spend at least half of the CPRIT grant and matching monies within the State of Texas with Texas-based employees or contractors.

About Salarius Pharmaceuticals

Salarius Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company developing cancer therapies for patients that need them the most. Salarius’ lead candidate, seclidemstat, is being studied as a potential treatment for pediatric cancers, solid tumors and other cancers with limited treatment options. Seclidemstat is currently in a Phase 1/2 clinical trial for relapsed/refractory Ewing sarcoma, for which it has received Fast Track Designation, Orphan Drug Designation and Rare Pediatric Disease Designation from the U.S. Food and Drug Administration. Salarius is also developing seclidemstat for several cancers with high unmet medical need, with a second Phase 1/2 clinical study in advanced solid tumors, including prostate, breast, and ovarian cancers. Salarius previously disclosed that a refractory Ewing sarcoma patient treated with seclidemstat for six months demonstrated a reduction of over 80% in prospectively defined target lesions. Target lesions generally represent a patient’s largest measurable tumors. However, at eight weeks, an increase in non-target lesions resulted in an overall patient classification of progressive disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST). Salarius has received financial support from the National Pediatric Cancer Foundation to advance the Ewing sarcoma clinical program and was also the recipient of an up to $18.7 million Product Development Award from the Cancer Prevention and Research Institute of Texas (CPRIT).
