Targeted protein degrader SP-3164 on track for IND submission in first half of 2023 with clinical trial to begin in second half of 2023
HOUSTON, March 27, 2023 (GLOBE NEWSWIRE) -- Salarius Pharmaceuticals, Inc. (Nasdaq: SLRX), a clinical-stage biopharmaceutical company using protein inhibition and protein degradation to develop cancer therapies for patients in need of new treatment options, today reported financial results for the three and 12 months ended December 31, 2022 and provided a business update.
Financial Highlights
- Cash and cash equivalents were $12.1 million as of December 31, 2022, compared with $29.2 million as of December 31, 2021. Subsequent to the close of 2022, the company received $1.5 million from the Cancer Prevention and Research Institute of Texas (CPRIT)
- Net loss for 2022 was $31.6 million, or $14.88 per share, compared with a net loss for 2021 of $12.8 million, or $7.72 per share. The 2022 net loss included a one-time non-cash expense of $8.9 million, or $4.17 per share due to a loss on impairment of goodwill
- Net loss for the fourth quarter of 2022 was $6.4 million, or $2.83 per share, compared with a net loss for the fourth quarter of 2021 of $4.1 million, or $2.27 per share, reflecting higher operating expenses including an increase in research and development expenses associated with the development of our targeted protein degrader, SP-3164
“We believe Salarius had an extremely productive fourth quarter and is well-positioned to take advantage of the recently announced and encouraging SP-3164 preclinical cell line and animal model data. We plan to file an IND with the FDA and initiate an SP-3164 clinical trial this year,” said David Arthur, president and chief executive officer.
“In addition, we believe the seclidemstat clinical trial data presented by MD Anderson Cancer Center researchers at the 2022 American Society of Hematology Annual Meeting and the Ewing sarcoma clinical trial data released by Salarius confirm that seclidemstat represent a potential lifeline to patients who are in desperate need of new treatment options. While the partial clinical trial holds have been a setback, we are optimistic about seclidemstat’s potential in treating Ewing sarcoma as well as blood cancers, and we look forward to restarting enrollment as quickly as possible,” Mr. Arthur added.
Targeted Protein Degrader (Molecular Glue) Highlights
- Continued to advance plans for filing an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) for SP-3164 in the first half of 2023 and begin a Phase 1/2 clinical trial in the second half of 2023
- SP-3164 data highlights from the American Society of Hematology (ASH) Annual Meeting include:
- Significant single-agent activity in diffuse large B-cell lymphoma (DLBCL) cell lines and mouse models showed superiority to lenalidomide (Revlimid®)
- SP-3164 in combination with the approved anti-CD20 drug, rituximab, resulted in complete tumor regressions in 50% of mice, and performed significantly better than the approved regimen of lenalidomide (Revlimid®) and rituximab
- Rapid and efficient Ikaros1 degradation compared with other studied molecular glues
- Antiproliferative effects across several non-Hodgkin’s lymphoma (NHL) cell lines
- Two abstracts were accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting in April 2023:
- One presentation is titled “SP-3164, a novel Ikaros and Aiolos1 molecular glue degrader with preclinical activity in non-Hodgkin lymphomas” and demonstrates that SP-3164 is a novel, orally available, cereblon-binding molecular glue with significant anticancer activity in NHL cell lines and mouse models
- The second presentation is titled “SP-3164, a novel molecular glue degrader with activity in preclinical models of multiple myeloma” and demonstrates that SP-3164 is a potent cereblon-binding molecular glue with the ability to rapidly degrade cancer-promoting transcription factors proteins and induce cell death in multiple myeloma cell lines; in multiple myeloma mouse models; and, that SP-3164 has superior single agent and combination treatment activity compared to approved molecular glues
- Announced the issuance of a new composition of matter U.S. patent for a second, next-generation targeted protein degrader, SP-3204
- The company’s targeted protein degrader intellectual property portfolio now includes 16 issued patents across six patent families
Seclidemstat (Targeted Protein Inhibitor) Highlights
- MD Anderson researchers presented data at ASH showing that in patients with myelodysplastic syndrome or chronic myelomonocytic leukemia, the combination of seclidemstat with azacitidine appeared safe at current dose levels and showed initial signs of potential activity
- There was a 50% overall response rate among eight evaluable patients who relapsed or progressed after standard of care hypomethylating agent therapy
- Salarius reported interim data from its Phase 1/2 study in Ewing sarcoma and FET-rearranged sarcomas showing:
- A 60% confirmed disease control rate and 7.4 months median time to tumor progression for Ewing sarcoma first-relapse patients
- No disease progression observed in either first- or second-relapse Ewing sarcoma patients who achieved confirmed disease control
- During the fourth quarter, enrollment of new patients in the Salarius-sponsored Phase 1/2 sarcoma clinical trial and the University of Texas MD Anderson investigator-initiated hematologic clinical trial was voluntarily paused, and then subsequently placed on partial clinical hold by the FDA. Salarius has worked to gather and analyze requested data and plans to submit its findings to the FDA with the goal of restarting its clinical trials, while MD Anderson works in parallel to provide its information to the FDA
“In summary, we believe our near-term future is promising and that our protein degradation assets hold great potential in treating blood cancers, and we are looking forward to beginning the SP-3164 clinical trial later this year. We are also excited about the encouraging seclidemstat clinical data generated to date. I’m looking forward to a great 2023 and beyond,” concluded Mr. Arthur.
1 Ikaros and Aiolos are transcription factors, or proteins, that play a critical role in regulating B and T cell development and have been associated with the development and progression of hematologic or blood cancers
Fourth Quarter Financial Results
Net loss for the fourth quarter of 2022 was $6.4 million, or $2.83 per share, compared with a net loss for the fourth quarter of 2021 of $4.9 million, or $2.27 per share. The increase was due to higher operating expenses including development spending on SP-3164, which was acquired in January 2022.
Research and development expenses were $4.7 million in the fourth quarter of 2022, compared with $2.7 million in the fourth quarter of 2021. The increase was principally due to costs associated with SP-3164, partially offset by lower costs related to SP-2577.
Net cash used for operating activities during the fourth quarter of 2022 was $4.7 million, compared with $2.7 million during the same quarter in 2021, reflecting the above-mentioned SP-3164 spending during the current period.
Full Year Financial Results
Net loss for 2022 was $31.6 million, or $14.88 per share, compared with a net loss for 2021 of $12.8 million, or $7.72 per share. The increase was primarily due to a $8.9 million one-time non-cash expense for impairment of goodwill, higher research and development expenses primarily resulting from the acquisition and development of SP-3164, higher seclidemstat development costs and higher general and administrative expenses. The 2021 period included grant revenue of $1.8 million, with no such revenue in 2022.
Research and development expenses were $15.8 million in 2022, compared with $8.5 million in 2021. The increase was principally due to costs associated with SP-3164, partially offset by lower costs related to SP-2577.
General and administrative expenses were $7.1 million in 2022, compared with $6.1 million in 2021, with the increase mainly driven by higher legal cost, public company cost and personnel cost.
Net cash used in operating activities for 2022 was $17.6 million, compared with $10.2 million for 2021. The increase was primarily due to higher research and development expenses.
As of December 31, 2022, Salarius had cash, cash equivalents and restricted cash of $12.1 million, compared with $29.2 million as of December 31, 2021. Current cash and cash equivalents are expected to fund the company’s planned operations into the fourth quarter of 2023.
