Sutro Biopharma (NASDAQ: STRO) presented expanded data from the dose-optimization portion of the REFRαME-O1 trial for luveltamab tazevibulin (luvelta) in platinum resistant ovarian cancer at SGO 2025. The study demonstrated:
At the optimized dose of 5.2 mg/kg + G-CSF (followed by 4.3 mg/kg), luvelta achieved:
- 32% overall response rate (ORR) and 96% disease control rate (DCR), compared to 13.8% ORR and 69% DCR at 4.3 mg/kg
- Consistent clinical activity across FRα expression levels ≥25%
- 30.8% ORR and 100% DCR for positive staining 2+ ≥75%
- 33.3% ORR and 91.7% DCR for PS2+ <75%
The safety profile remained consistent across dosing groups, with manageable neutropenia. However, Sutro announced it is deprioritizing luvelta's development across all indications and is seeking out-licensing opportunities.

Sutro Biopharma (STRO) and Boehringer Ingelheim BioXcellence™ have successfully scaled up Sutro's proprietary cell-free expression technology to commercial scale manufacturing. The collaboration achieved production of luveltamab tazevibulin (luvelta), Sutro's antibody-drug conjugate (ADC) for ovarian cancer treatment, at 4,500L scale in Boehringer's Vienna facility.
The breakthrough represents an industry milestone, marking the first successful transition from small-scale to large-scale GMP production using Sutro's cell-free protein synthesis platform. All manufactured batches met the required quality criteria for clinical studies. The platform's unique advantage lies in its modular approach, utilizing non-natural amino acids for site-specific protein conjugation, potentially offering improved safety and efficacy profiles compared to traditional ADC production methods.
This achievement validates the commercial viability of Sutro's technology and can be applied to their pipeline of next-generation ADCs targeting various cancers. Sutro is actively seeking business development partners to advance their technology platform and product pipeline.
