Abstract
Background: AVA6000 is a peptide drug conjugate, consisting of a peptide moiety that is specifically cleaved by FAP in the TME that is bound to doxorubicin. FAP is selectively overexpressed in many solid tumors. The peptide moiety linker (pre|CISIONTM) prevents cellular entry of doxorubicin unless cleaved by FAP, thus enabling targeted delivery of doxorubicin to tumors.
Design: The safety, PK and preliminary efficacy of AVA6000 was studied in a first-in-man, multicenter dose escalation phase I trial. AVA6000 was administered intravenously q3w using a standard 3+3 design in patients with locally advanced or metastatic solid tumors reported to be FAP-positive. PK (AUC) based dosing was implemented to calculate maximum cycles of AVA6000 with the cumulative limit of 550 mg/m2.
Results: Forty patients (median age 65 years, range 30-79), with median 3 prior lines of therapy (range, 0-7) received escalating AVA6000 doses from 80mg/m2 (51 mg/m2 doxorubicin; molar equivalent, 0.675) to 385 mg/m2 (260 mg/m2 doxorubicin equivalent). Tumor types included soft tissue sarcoma (30%), colorectal cancer (27.5%), pancreatic cancer (20%), cancers of the biliary tract (7.5%).
