• Pivotal Complete Response (CR) Data from SELECT-MDS-1 Phase 3 Trial Expected in Mid-November 
• Management to Host Conference Call at 8:30 AM ET Today 

CAMBRIDGE, Mass. / Oct 31, 2024 / Business Wire / Syros Pharmaceuticals (NASDAQ: SYRS), a biopharmaceutical company committed to advancing new standards of care for the frontline treatment of hematologic malignancies, today reported financial results for the quarter ended September 30, 2024 and provided a business update.

“It is a very exciting time at Syros, as we approach a significant milestone in our efforts to establish tamibarotene as a potential new standard of care for higher-risk myelodysplastic syndrome (HR-MDS) patients with RARA gene overexpression. We expect to announce topline results from the pivotal SELECT-MDS-1 Phase 3 trial in mid-November, and if successful, we plan to file our first New Drug Application (NDA) and to launch tamibarotene in the U.S.,” said Conley Chee, Chief Executive Officer of Syros.

“We believe there is a tremendous opportunity for tamibarotene in the HR-MDS frontline setting. With approximately 9,000 newly diagnosed HR-MDS patients annually in the U.S. – approximately 50% of whom overexpress RARA – tamibarotene is uniquely positioned to address the unmet need, as no new therapies beyond hypomethylating agents (HMAs) have been approved in over a decade. Leveraging our own commercial capabilities and experienced leadership team, we are well-equipped to bring tamibarotene to patients,” Mr. Chee continued.

UPCOMING MILESTONES

• Report pivotal CR data from the SELECT-MDS-1 Phase 3 trial in newly diagnosed HR-MDS patients with RARA gene overexpression in mid-November 2024.

Third Quarter 2024 Financial Results

• Syros did not recognize revenue in the third quarter of 2024, as compared to $3.8 million for the third quarter of 2023. The decrease reflects the termination of Syros’ collaboration agreement with Pfizer.
• Research and development (R&D) expenses were $20.5 million for the third quarter of 2024, as compared to $28.3 million for the third quarter of 2023. The decrease was primarily due to the reduction in external R&D consulting, contract manufacturing, and a reduction in headcount and related expenses.
• General and administrative (G&A) expenses were $5.7 million for the third quarter of 2024, as compared to $7.8 million for the third quarter of 2023. The decrease was primarily due to a reduction in headcount and related expenses, consulting fees, and facilities expenses.
• For the third quarter of 2024, Syros reported a net loss of $6.4 million, or $0.16 per share, compared to a net loss of $40.1 million, or $1.43 per share, for the same period in 2023.

Cash and Financial Guidance

Cash and cash equivalents as of September 30, 2024, were $58.3 million, as compared with $79.0 million as of June 30, 2024.

Based on its current plans, Syros believes that its existing cash and cash equivalents will be sufficient to fund its anticipated operating expenses and capital expenditure requirements into the third quarter of 2025.
