About Coiled Therapeutics plc

Coiled Therapeutics (AIM: COIL) is an AIM-listed, clinical-stage biotechnology company focused on developing innovative precision oncology therapies. Its lead programme, AO-252, is a novel TACC3 inhibitor currently in Phase I clinical trials in the USA (trials ID: NCT06136884). Coiled Therapeutics is actively enrolling patients to test for safety and efficacy in patients whose cancer has progressed on other treatments. The Company is also assessing its STAT-6 siRNA programme for immunology indications. Coiled Therapeutics is supported by a leadership team with a proven track record in drug development and strategic backing from A2A Pharmaceuticals.

About AO-252

AO-252 is a first-in-class, orally administered, brain-penetrant small molecule inhibitor of Transforming Acidic Coiled-Coil containing protein 3 (TACC3). TACC3 is a validated oncology target that is frequently overexpressed in many aggressive, hard-to-treat solid tumours but is dispensable in normal adult cells, providing a wide therapeutic window.

By selectively disrupting cancer-critical protein-protein interactions at the TACC3 C-terminal domain, AO-252 induces mitotic and replication stress, impairs DNA damage repair, and triggers cancer cell death. Notably, AO-252 has demonstrated the ability to cross the blood-brain barrier, addressing a significant unmet medical need for the treatment of brain metastases.

The asset is currently in an ongoing Phase I open-label dose-escalation study and early clinical signals have shown encouraging anti-tumour activity and a benign safety profile, with the Company planning to initiate dose expansion cohorts in lead indications, including prostate and ovarian cancer, during 2026.
