Avacta Unaudited 2025 Preliminary Results (May 19): FOCUS-01 First Patient Dosed March 2026 in Phase 1 AVA6103 (FAP-Exatecan pre|CISION-Enabled PDC)
Avacta Therapeutics reported unaudited preliminary results for the 12 months ended December 31, 2025 on Tuesday May 19, 2026, and disclosed that the first patient received treatment in FOCUS-01 — the Phase 1 clinical trial of AVA6103, a FAP-activated exatecan peptide-drug conjugate — in March 2026. AVA6103 is the second pre|CISION-enabled candidate in the Avacta clinical pipeline, after AVA6000 (FAP-Dox, which has Phase Ia/Ib data scheduled at ASCO 2026 in salivary gland cancers). The pre|CISION platform attaches a peptide tetrazolyl moiety cleaved by FAP (fibroblast activation protein) overexpressed in cancer-associated fibroblasts, allowing systemic administration of cytotoxic payloads without the dose-limiting toxicity that constrains free exatecan. FOCUS-01 is enrolling adults with advanced solid tumors. AVA6103 expands the platform from doxorubicin (in AVA6000) to exatecan — a topoisomerase I inhibitor with potency advantages in HER2-low and triple-negative breast cancer.
