Avacta Group PLC has announced the opening of its Phase 1 trial for FAP-Exd (AVA6103), a sustained-release peptide-drug conjugate utilizing the pre|CISION® platform, with the first patient expected to enroll before the end of March. This trial will evaluate the safety, pharmacokinetics, and preliminary efficacy of AVA6103 in patients with advanced pancreatic, cervical, vulvar, gastric, gastroesophageal junction, or small cell lung cancers, with parallel arms investigating two administration schedules. Preliminary safety and pharmacokinetic data are anticipated in the second half of 2026, following the opening of clinical sites in Virginia and Texas. Disclaimer*

FAP-Exd (AVA6103) is a fibroblast activation protein (FAP)-released version of exatecan, a highly potent topoisomerase I inhibitor.\n \nThe Phase 1a dose escalation portion of the clinical trial will evaluate the safety, tumor and plasma pharmacokinetics and preliminary efficacy of AVA6103 in patients diagnosed with one of four solid tumors in the advanced setting: pancreatic cancer, cervical and vulvar cancer, gastric and gastroesophageal junction cancers and small cell lung cancer. The trial is designed to identify a dose and regimen for further clinical development.\n \nThe first patient is anticipated to enroll in the study before the end of March. Adult participants will be enrolled in the Phase 1a dose-escalation portion of the trial with parallel arms investigating two schedules of administration (every two weeks; Q2W, and every three weeks; Q3W), with preliminary safety and pharmacokinetic data anticipated in the second half of 2026.\n \nThe first two centers to open for enrollment are the Virginia Cancer Specialists (VCS) Research Institute in Fairfax, Virgina, and NEXT Oncology Specialists in Dallas, Texas.\n \nChristina Coughlin, CEO of Avacta Therapeutics, commented:\n \n\"The opening of the first clinical sites in the Phase 1 trial of AVA6103 is an important milestone. It is notable that this program continues to move into clinical development faster than normal industry timelines. With our proprietary sustained release mechanism, we expect AVA6103 to enable greater efficacy from the exatecan payload while limiting the severe toxicities that were observed in the initial development of this payload in the cli...
