-- Management to Host Conference Call at 8:30 AM ET Today --

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 June 30, 2024 and provided a corporate update.

“Syros is well-positioned heading into key clinical data readouts expected in the second half of 2024, including pivotal complete response (CR) data from the Phase 3 SELECT-MDS-1 trial by mid-fourth quarter. In addition, we will present clinical activity and tolerability data from over 40 patients from the SELECT-AML-1 Phase 2 trial at the SOHO 2024 annual meeting in September,” said Conley Chee, Chief Executive Officer of Syros. “We are keenly focused on execution across our late-stage clinical development programs and pre-commercial activities in support of our mission to provide tamibarotene as a new frontline standard-of-care for patients with RARA overexpression.

“Supported by compelling, consistent clinical data generated to-date across multiple trials, we believe our differentiated and biologically-targeted approach with tamibarotene provides a meaningful opportunity to address the approximately 50% of higher-risk MDS and 30% of AML patients with RARA overexpression. There is a significant unmet need in these two closely related diseases, with patients and physicians looking for new, convenient, and well-tolerated options that enhance clinical outcomes while maintaining quality of life. As we approach two critical data readouts, we are working diligently to prepare for our first New Drug Application (NDA) filing and launch, so that we can effectively deliver tamibarotene to the thousands of HR-MDS patients in need of new treatment options. We look forward to an exciting second half of the year and remain committed in our pursuit to provide profound benefit to patients in need,” 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 by the middle of the fourth quarter of 2024.
• Report clinical activity and tolerability data from a prespecified analysis of more than 40 patients from the SELECT-AML-1 Phase 2 trial in unfit AML patients with RARA overexpression at the 12^th Annual Meeting of the Society of Hematologic Oncology (SOHO) meeting in September 2024.

RECENT HIGHLIGHTS

• In June, Syros hosted a webinar event to discuss disease biology and the current treatment landscape in HR-MDS, as well as to highlight the design of the ongoing pivotal Phase 3 SELECT-MDS-1 trial and the opportunity for tamibarotene. In addition to Syros management, the event featured presentations from medical experts in MDS. An archived replay of the event is available on the Investors & Media section of Syros’ website, www.syros.com.

Second Quarter 2024 Financial Results

• Syros did not recognize revenue in the second quarter of 2024, as compared to $2.8 million for the second quarter of 2023. The decrease reflects last year’s termination of Syros’ collaboration agreement with Pfizer.
• Research and development (R&D) expenses were $22.0 million for the second quarter of 2024, as compared to $29.6 million for the second 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 $5.5 million for the second quarter of 2024, as compared to $7.2 million for the second quarter of 2023. The decrease was primarily due to a reduction of headcount and related expenses, consulting fees, and facilities expenses.
• For the second quarter of 2024, Syros reported a net loss of $23.3 million, or $0.59 per share, compared to a net loss of $36.3 million, or $1.30 per share, for the same period in 2023.

Cash and Financial Guidance

Cash, cash equivalents and marketable securities as of June 30, 2024, were $79.0 million, as compared with $108.3 million as of March 31, 2024.

Based on its current plans, Syros believes that its existing cash, cash equivalents and marketable securities will be sufficient to fund its anticipated operating expenses and capital expenditure requirements into the third quarter of 2025, beyond pivotal Phase 3 data from the SELECT-MDS-1 trial and additional data from the randomized portion of the SELECT-AML-1 trial.
