Syros Receives Fast Track Designation from the FDA for Tamibarotene for the Treatment of Newly Diagnosed Unfit AML with RARA gene overexpression

Syros Pharmaceuticals (NASDAQ:SYRS), a biopharmaceutical company committed to advancing new standards of care for the frontline treatment of hematologic malignancies, today announced that the United States Food and Drug Administration (FDA) has granted Fast Track Designation to tamibarotene in combination with azacitidine and venetoclax for the treatment of newly diagnosed acute myeloid leukemia (AML) with RARA overexpression as detected by an FDA approved test in adults who are over age 75 years or who have comorbidities that preclude the use of intensive induction chemotherapy. Tamibarotene, an oral first-in-class selective retinoic acid receptor alpha (RARα) agonist, is currently being evaluated in combination with venetoclax and azacitidine for the treatment of newly diagnosed AML patients with RARA gene overexpression.

“We are pleased to receive Fast Track designation for tamibarotene for the treatment of AML. This designation reflects the tremendous need for a safe and effective therapy, which can improve the clinical outcomes and prognosis among people diagnosed with AML, many of whom cannot tolerate intensive treatment,” said David A. Roth, M.D., Chief Medical Officer of Syros Pharmaceuticals. “We are particularly encouraged to secure Fast Track designation following initial randomized data from a prespecified interim analysis of our ongoing SELECT-AML-1 clinical trial, in which treatment with our RARα agonist, tamibarotene, in combination with venetoclax and azacitidine resulted in a 100% CR/CRi rate compared with a 70% CR/CRi rate for the comparator of venetoclax and azacitidine. Additionally, tamibarotene in combination with venetoclax and azacitidine demonstrated no added toxicity relative to venetoclax and azacitidine alone. We look forward to sharing additional data from SELECT-AML-1 later this year, and to potentially accelerate the delivery of tamibarotene as a new frontline option for the approximately 30% of AML patients who are positive for RARA overexpression.”

Fast Track is a process designed by the FDA to facilitate the development and expedite the review of drug candidates intended to treat serious conditions and for which nonclinical or clinical data demonstrate the potential to address unmet medical need. The purpose is to facilitate development and expedite review of drugs to treat serious and life-threatening conditions, to bring the approved products to patients earlier. A therapeutic candidate that receives Fast Track designation may be eligible for more frequent interactions with the FDA to discuss the therapeutic candidate’s development plan. Therapeutic candidates with Fast Track designation may also be eligible for priority review and accelerated approval if supported by clinical data.
