LONDON AND PHILADELPHIA - July 30, 2025 - Avacta Therapeutics (AIM: AVCT, 'the Company'), a life sciences company developing innovative, targeted oncology drugs, today announces that the Company will present an updated data analysis from the Phase 1a trial of FAP-Dox (AVA6000) at the 2025 European Society for Medical Oncology (ESMO) Congress, in Berlin, Germany, taking place from October 17-21, 2025. AVA6000 is a peptide drug conjugate consisting of doxorubicin conjugated with a peptide moiety that is specifically cleaved by FAP in the tumor microenvironment.

The poster presentation will be based on the most recent data analysis from the Phase 1a trial of FAP-Dox (AVA6000) in patients with Fibroblast Activation Protein (FAP)-positive solid tumors. Avacta completed the Phase 1a enrollment dose escalation portion of the clinical trial in late 2024, with patient enrollment ongoing in multiple dose expansion cohorts of a Phase 1b study.

Abstract details are listed below and available online on the ESMO website.

Avacta will hold an investor event shortly after the ESMO presentation. Further details will be made available nearer the time.

Title: A Phase I trial of FAP-Dox (AVA6000), a Fibroblast Activation Protein (FAP)-released and tumor microenvironment (TME)-targeted doxorubicin peptide drug conjugate in patients with FAP-positive solid tumors

Session Title: Developmental Therapeutics

Session Date and Time: 17 October, 19:40 - 20:00

Location: Berlin Auditorium - Hub 27

Abstract Presentation Number: 964P

Speaker: William D. Tap

About the preCISION® Platform
The preCISION® platform comprises an anticancer payload conjugated to a proprietary peptide that is a highly specific substrate for fibroblast activation protein (FAP) which is upregulated in most solid tumors compared with healthy tissues. The preCISION® platform harnesses this tumor specific protease to cleave preCISION® peptide drug conjugates and preCISION® antibody/Affimer® drug conjugates in the tumor microenvironment, thus releasing active payload in the tumor and reducing systemic exposure and toxicity, allowing dosing to be optimized to deliver the best outcomes for patients.
