The candidate, M1231, was discovered using Sutro's XpressCF and XpressCF+ drug discovery and manufacturing technologies and includes a proprietary linker-warhead also discovered by Sutro. M1231 is a MUC1-EGFR bispecific antibody drug conjugate (ADC) for the treatment of solid tumors and relies on the strand-exchange engineered domain (SEED) platform from

About
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 1 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
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.
