About Coiled Therapeutics plc

Coiled Therapeutics (AIM: COIL) (OTCQB: COTXF) is an AIM-listed, clinical-stage precision oncology company advancing first-in-class small molecule therapies targeting validated cancer dependencies. Its lead programme, AO-252, is a novel TACC3 inhibitor currently being evaluated in an ongoing Phase I clinical trial in the U.S. (ClinicalTrials.gov ID: NCT06136884). The Company's clinical development strategy focuses on generating evidence in selected tumour types, including ovarian and prostate cancer, to support potential pharmaceutical partnerships. Its broader pipeline includes a STAT-6 siRNA programme for immunology indications.

About AO-252

AO-252 is a first-in-class, orally administered, brain-penetrant small molecule designed to selectively inhibit Transforming Acidic Coiled-Coil containing protein 3 (TACC3). TACC3 has emerged as a validated cancer dependency across multiple aggressive solid tumours and is largely dispensable in normal adult cells, supporting the potential for a broad therapeutic window.

By disrupting TACC3-driven protein interactions, AO-252 induces mitotic and replication stress, impairs DNA damage repair and promotes cancer cell death. Its ability to cross the blood-brain barrier is a key differentiator, supporting its potential to treat both primary brain tumours and brain metastases.

The Company is currently enrolling patients in dose-escalation cohorts evaluating the new lipid-based softgel formulation of AO-252. Phase I/II dose-expansion cohorts in ovarian and prostate cancer are planned to follow once the optimal dose has been established.
