Sutro Biopharma Announces Extension of First Cytokine Derivative Research Program Under Collaboration with Merck
“At Sutro, our proprietary and integrated cell-free protein synthesis and site-specific conjugation platform XpressCF+™ enables us to design and develop next-generation targeted product candidates by innovating beyond the constraints of cell-based systems,” said Sutro CEO, Bill Newell. “The advancement of our novel cytokine-derivative product candidate towards IND-enabling studies marks another important step forward in our collective goal of improving the outcomes for cancer patients.”
“In all three of our current collaborations, and in three distinct therapeutic protein formats, we have progressed product candidates either into clinical development or to the late stages of preclinical development,” said Sutro Chief Scientific Officer, Trevor Hallam, PhD. “These successes with Merck and with each of our other collaborators demonstrate the power and agility of our rapid and precise engineering platform.”
About Sutro Biopharma
Sutro Biopharma, Inc., located in South San Francisco, is a clinical-stage drug discovery, development and manufacturing company. Using precise protein engineering and rational design, Sutro is advancing next-generation oncology therapeutics.
Sutro’s proprietary and integrated cell-free protein synthesis platform XpressCF® and site-specific conjugation platform, XpressCF+™, led to the discovery of STRO-001 and STRO-002, Sutro’s first two internally-developed ADCs. STRO-001 is a CD74-targeting ADC currently being investigated in a Phase I clinical trial of patients with advanced B-cell malignancies, including multiple myeloma and non-Hodgkin lymphoma. STRO-001 was granted Orphan Drug Designation by the FDA for multiple myeloma in October 2018. STRO-002 is a folate receptor alpha (FolRα)-targeting ADC, currently being investigated in a Phase I clinical trial of patients with ovarian and endometrial cancers. This is the second product candidate to be evaluated in clinical trials resulting from Sutro’s XpressCF® and XpressCF+™ technology platforms. A third program, CC-99712 (BCMA-targeting ADC), which is part of Sutro’s collaboration with Bristol-Myers Squibb (formerly Celgene Corporation), recently began enrolling patients for its Phase I clinical trial of patients with multiple myeloma. Sutro’s proprietary technology was responsible for the discovery and manufacturing of CC-99712, for which Bristol-Myers Squibb has worldwide development and commercialization rights. Sutro is entitled to development and regulatory milestone payments and tiered royalties from Bristol-Myers Squibb for this BCMA ADC.
Sutro is dedicated to transforming the lives of cancer patients by creating medicines with improved therapeutic profiles for areas of unmet need.
To date, Sutro has designed cytokine-based immuno-oncology therapies, ADCs, vaccines and bispecific antibodies primarily directed at clinically-validated targets for which the current standard of care is suboptimal.
Sutro’s platform allows it to accelerate discovery and development of potential first-in-class and best-in-class molecules through rapid and systematic evaluation of protein structure-activity relationships to create optimized homogeneous product candidates.
In addition to developing its own oncology pipeline, Sutro is collaborating with select pharmaceutical and biotech companies to discover and develop novel, next-generation therapeutics. As the pace of clinical development accelerates, Sutro and its partners are developing therapeutics designed to more efficiently kill tumors without harming healthy cells.
