Salarius Pharmaceuticals Reports Business Highlights and Third Quarter 2020 Financial Results

Conference Call and Live Audio Webcast Scheduled for Today, November 11, 2020, at 4:30 p.m. ET

HOUSTON, Nov. 11, 2020 (GLOBE NEWSWIRE) — Salarius Pharmaceuticals, Inc. (Nasdaq: SLRX), a clinical-stage biopharmaceutical company developing potential new medicines for children and adults with pediatric cancers, solid tumors and other cancers, today reported its corporate and financial results for the third quarter ended September 30, 2020.

Recent Business and Corporate Events:

  • Ewing sarcoma Phase 1/2 clinical trial is completing dose escalation to establish maximum tolerated dose (MTD) and is expected to advance into Phase 2 dose-expansion in Q1 2021
  • Ewing sarcoma clinical trial expansion phase expanded to include patients with Ewing-related sarcomas such as myxoid liposarcoma, desmoplastic small round cell tumors and other sarcomas with similar biology to Ewing sarcoma
     º Ewing sarcoma and Ewing-related sarcomas represent rare cancers affecting both children and adults where there is a high unmet need for additional treatment options

Financial Highlights:

  • Total cash and cash equivalents of $9.6 million as of September 30, 2020 due in part to $6.2 million gross proceeds in an underwritten public offering closed August 3, 2020
  • Three-month period ended September 30, 2020 net loss per common share – basic and diluted – of $0.10, compared to $0.73 for the same period ended September 30, 2019

“The events of the third quarter of 2020 affirm the company’s growth strategy and demonstrate the potential of seclidemstat as a treatment for cancers with high unmet need,” said David Arthur, President and CEO of Salarius. “Our lead clinical program in Ewing sarcoma continues to advance, and we expect to reach the maximum tolerated dose (MTD) in the Phase 1 portion of the clinical trial and, as planned, begin the Phase 2 dose-expansion portion of the trial in Q1 2021.  This is an important milestone as it allows us to establish the recommended Phase 2 dosing regimen for the trial and begin treating a broader group of patients with Ewing and Ewing-related sarcomas.”

Mr. Arthur continued, “Ewing sarcoma and advanced solid tumors (AST) remain our most advanced development programs, but we believe seclidemstat offers the opportunity to address numerous cancers where additional treatment options are needed.  In this regard, we recently expanded the dose-expansion phase of the Ewing sarcoma clinical trial to include several additional sarcomas.  This decision was based on preclinical data and early clinical data observations from the ongoing clinical trials that suggest seclidemstat may demonstrate drug activity and have applicability in other sarcomas that have a similar gene arrangement to Ewing sarcoma, known as Ewing-related sarcomas.  Among those observations, 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, which generally represent a patient’s largest measurable tumors.”

Ewing Sarcoma Clinical Trial Expanded
On July 29, 2020, Salarius announced the expansion of its ongoing Phase 1/2 clinical trial of seclidemstat in Ewing sarcoma to include additional select sarcomas that share a similar biology to Ewing sarcoma, also known as Ewing-related sarcomas.  Sarcomas of interest include myxoid liposarcoma, desmoplastic small round cell tumors and other sarcomas that harbor similar FET family gene rearrangements to Ewing sarcoma.

These Ewing-related sarcomas were chosen based on their underlying biology as well as preclinical data and early clinical observations involving seclidemstat that suggest the drug may demonstrate activity and may have applicability in several sarcomas that share key characteristics of Ewing sarcoma.  As Salarius previously disclosed, 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).

The amendment to the ongoing clinical trial will allow up to 30 patients with Ewing-related sarcomas to enroll in the trial’s upcoming dose-expansion phase, which is in addition to the 20 Ewing sarcoma patients also planned to be treated in the dose-expansion phase. 

Additional Clinical Trials to Expand Development Program
Mr. Arthur concluded, “In addition, in the third quarter we continued preparatory work on two additional clinical trials and look forward to announcing the initiation of these trials soon.  These additional clinical trials support our growth strategy focused on maximizing the market potential of seclidemstat.”  

Three-Month Financial Results:
For the three-month period ended September 30, 2020, Salarius’ reported net loss was $1.7 million, or $0.10 per basic and diluted share, compared to a net loss of $2.6 million, or $0.73 per basic and diluted share for the same period in 2019.  The loss before other income for the three-month period ended September 30, 2020 decreased by $2.0 million compared to the same time span last year, primarily due to a $2.2 million decrease in general and administrative expenses which more than offset the increase of $0.7 million in research and development expenses. Increased research and development costs resulted from increased clinical trial expenses and drug manufacturing costs. The decrease in general and administrative costs resulted from the absence of costs related to Salarius’ one-time transformation into a public company during 2019 which did not reoccur in the current period.

As of September 30, 2020, total cash, cash equivalents and restricted cash were $9.6 million, compared to $3.7 million at year-end 2019. Increases in cash balances result from the Company’s public offerings of stock in the first quarter and third quarter 2020.  The Company expects its cash and cash equivalents to fund its operations into the third quarter of 2021.

$6.2 Million Underwritten Public Offering
On August 3, 2020, Salarius completed an underwritten public offering with total gross proceeds of approximately $6.2 million, prior to deducting underwriting discounts and commissions and offering expenses payable by Salarius. Salarius intends to use the net proceeds from the offering and ongoing non-dilutive financial support from the Cancer Prevention Institute of Texas (CPRIT) to fund the expansion of the Ewing sarcoma clinical trial and ongoing company operations.
