Sutro Biopharma, Inc. - STRO STOCK NEWS

Sutro Biopharma (NASDAQ: STRO) announced five presentations at the 15th Annual World ADC Conference in San Diego, November 4-6, 2024. The presentations cover various aspects of ADC innovation, including: dual-payload ADCs development, clinical updates on Luvelta targeting folate receptor, preclinical development of STRO-004, cell-free protein synthesis for site-specific conjugation, and optimization of high DAR and dual payload ADCs. The presentations will be available on Sutro's website after the event.

Sutro Biopharma has initiated REFRαME-P1, a registration-enabling trial of luveltamab tazevibulin (luvelta) for pediatric patients with CBF/GLIS AML. The study follows encouraging compassionate use data presented in December 2023, showing 42% complete remission in patients with ≥5% blasts. CBF/GLIS AML is a rare, aggressive leukemia affecting infants and young children, with an average onset age of 18 months and over 80% chemotherapy resistance rate. The global trial will evaluate luvelta's efficacy and safety in children under 12 years with CBF/GLIS AML, with most sites planned to open by year-end.

Sutro Biopharma (NASDAQ: STRO) is hosting an investor webcast to showcase its proprietary cell-free platform and next-generation ADC innovation. The company highlights three approaches: increasing potency safely with higher drug-antibody ratio exatecan ADCs, combining payloads to overcome tumor resistance with dual-payload ADCs (ADC2), and delivering immunostimulatory ADCs (iADC) that combine immune activation with cytotoxic payloads.

Key highlights include:

• STRO-004, a tissue factor-targeting ADC, demonstrated greater anti-tumor activity and lower toxicities in preclinical models
• Plans to file an IND for STRO-004 in the second half of 2025
• Dual-payload ADCs (ADC2) show increased anti-tumor activity in preclinical models
• iADCs provide a novel mechanism of action, bridging innate and adaptive immunity
• Sutro plans to deliver three INDs over the next three years

Sutro Biopharma (NASDAQ: STRO) announced updated data from its Phase 1b study of luveltamab tazevibulin (luvelta) in combination with bevacizumab for epithelial ovarian cancer (EOC) at ESMO 2024. Key findings include:

- 56% objective response rate at the recommended phase 2 dose (RP2D) of 4.3 mg/kg luvelta with 15 mg/kg bevacizumab
- 35% overall response rate across all dose ranges
- Efficacy observed regardless of Folate Receptor-α (FRα) expression
- No new safety signals compared to individual agents
- Expansion phase ongoing with 23 additional patients; data expected in H1 2025

The combination shows promise as a non-biomarker driven approach for EOC treatment, potentially benefiting a broader patient population.

Sutro Biopharma (NASDAQ: STRO), a clinical-stage oncology company specializing in antibody drug conjugates (ADCs), has announced a Research Forum to showcase its pipeline of next-generation ADCs. The event is scheduled for October 10, 2024, at 1:30 p.m. PT / 4:30 p.m. ET and will be accessible via live webcast.

Sutro Biopharma (NASDAQ: STRO) has initiated the REFRαME-L1 global Phase 2 study of luveltamab tazevibulin (luvelta) for non-small cell lung cancer (NSCLC) patients with Folate Receptor-α (FRα) expressing tumors. The trial is now open for enrollment, with initial data expected in H1 2025. Luvelta, an antibody drug conjugate (ADC), shows promise in treating NSCLC patients with lower FRα expression profiles. The study targets a significant unmet need, as lung cancer is the leading cause of cancer-related deaths worldwide, with a 5-year survival rate as low as 8% for metastatic disease. Approximately 30% of adenocarcinoma NSCLC patients have FRα expression, making it an attractive therapeutic target.
