Sutro Biopharma Announces Oral Presentation at the 64th American Society of Hematology Annual Meeting and Exposition

SOUTH SAN FRANCISCO, Calif., Nov. 03, 2022 (GLOBE NEWSWIRE) -- Sutro Biopharma, Inc. (Sutro or the Company) (NASDAQ: STRO), a clinical-stage oncology company pioneering site-specific and novel-format antibody drug conjugates (ADCs), today announced that data from the Company’s compassionate use program on anti-leukemic activity of STRO-002, a novel folate receptor-α (FR-α) targeting ADC, in infants and children with relapsed/refractory CBF2AT3-GLIS2 acute myeloid leukemia (AML) will be reviewed in an oral presentation at the 64th American Society of Hematology Annual Meeting and Exposition (ASH). The meeting will take place December 10 – 13, 2022 in New Orleans, LA.

Soheil Meshinchi, M.D., Ph.D., Principal Investigator for the compassionate use program with STRO-002 in relapsed/refractory CBF2AT3-GLIS2 AML, will deliver the oral presentation at 10:45 a.m. CST on December 10, 2022. Dr. Meshinchi is Professor, Clinical Research Division, at Fred Hutchinson Cancer Research Center and Professor, Division of Pediatric Hematology-Oncology, at the University of Washington School of Medicine.

“As a patient-driven company, we at Sutro are extremely pleased that STRO-002— which we are presently developing in ovarian cancer—had a profound effect in a pediatric patient group with a rare form of AML, for which treatment options are limited,” said Bill Newell, Sutro’s Chief Executive Officer. “Among the highlights from our compassionate use program, there were a number of complete responses, which is particularly encouraging considering these patients are typically refractory to standard-of-care. We look forward to an oral presentation of the full data set at ASH in December.”
