Sutro Biopharma, Inc. (NASDAQ: STRO), a clinical-stage drug discovery, development and manufacturing company focused on the application of precise protein engineering and rational design to create next-generation oncology therapeutics, reported encouraging interim safety data from an ongoing Phase 1 dose escalation clinical trial of its product candidate STRO-001, a novel, specific and homogeneous anti-CD74 antibody-drug conjugate (ADC), as a potential therapy for patients with B-cell malignancies. The interim data from the trial includes 21 patients and separate dosing cohorts for multiple myeloma (10 MM patients) and non-Hodgkin lymphoma (11 NHL patients), was presented at the 24th European Hematology Association (EHA) Congress in Amsterdam. The data also showed encouraging preliminary anti-tumor activity for the ADC, including one complete response (CR) and one partial response (PR) among a cohort of heavily pre-treated patients with DLBCL. Overall, STRO-001 was generally well-tolerated.
Dr. Nirav Shah, Assistant Professor of Medicine at Medical College of Wisconsin said “CD74 is expressed on B cells throughout differentiation and appears to be an attractive target for the treatment of non-Hodgkin lymphoma and multiple myeloma”. “The interim safety results from the early dose escalation cohorts of the STRO-001 Phase 1 clinical trial are encouraging, especially considering the complete response seen in one of our patients.”
Bill Newell, Sutro’s Chief Executive Officer added, “There is a continuing need for new treatment options for patients with B-cell malignancies as many patients relapse or become refractory to even the newest treatment regimens. STRO-001 was designed to directly target cancer cells to deliver a cytotoxic payload, an approach that enables greater precision in treating tumors. We view the data as encouraging and believe that STRO-001 can be an important new treatment option to address an unmet need for patients with B-cell malignancies.”
The ongoing Phase 1, open-label, multicenter, dose escalation trial of STRO-001 is designed to evaluate the safety, tolerability and preliminary anti-tumor activity of STRO-001 in adults with B-cell malignancies. Based on interim data from the clinical trial through May 14, 2019, STRO-001 has been generally well-tolerated. The most common treatment emergent adverse events included fatigue, nausea, chills and infusion reactions. Neither ocular toxicity signals nor anti-drug antibodies have been observed and the maximum tolerated dose for both dosing cohorts has not been reached.
Sutro’s cell-free protein synthesis and site-specific conjugation (XpressCF+™) platform technology was used to discover and develop STRO-001, a CD74-targeting ADC. STRO-001 contains a potent maytansinoid warhead conjugated to two specific sites (drug-to-antibody ratio of 2) using a stable non-cleavable linker. The interim data as of May 14, 2019, included 21 patients across two cohorts: cohort A for MM and cohort B for NHL. The patients enrolled in the trial were generally heavily pre-treated with a median of six lines of prior therapy. STRO-001 was administered as a 60-minute IV infusion on Days 1 and 15 of a 28-day cycle until disease progression or dose limiting toxicity. As of May 14, 2019, the MM cohort was at dose level 0.65 mg/kg and the NHL dose cohort was at 0.91 mg/kg. The trial continues to enroll patients in dose escalation in both MM and NHL cohorts. This trial is registered with clinicaltrials.gov identifier NCT03424603.
