Products

STRO-004 (Tissue Factor-directed exatecan ADC)

Next-generation exatecan-based ADC targeting Tissue Factor with site-specific conjugation and high drug-to-antibody ratio; advancing in Phase 1 solid tumor studies.

STRO-006 (Integrin β6-directed ADC)

Integrin β6-targeting ADC designed to deliver exatecan payloads with optimized exposure and reduced platform toxicity; progressing toward clinical development.

STRO-227 (Dual-payload PTK7-directed ADC)

Dual-payload ADC combining complementary cytotoxic payloads to target PTK7-positive tumors; preclinical data indicate improved activity vs single-payload ADCs.

Luveltamab tazevibulin (FRα-targeting ADC, previously STRO-002)

Folate receptor-α targeting ADC evaluated in dose-optimization and Phase 1 studies for platinum-resistant ovarian cancer; demonstrated clinical activity in certain cohorts but later deprioritized for internal development.
