Zelluna Clears UK Regulatory Hurdle for First Human Trial of TCR-NK Therapy
Event summary
- Zelluna ASA received UK MHRA and Ethics approval to initiate ZIMA-101, a first-in-human Phase 1 clinical trial for ZI-MA4-1.
- The trial will evaluate safety and preliminary activity in patients with advanced solid cancers, including lung, ovarian, and head and neck cancers.
- Initial clinical data from the trial is expected to emerge from mid-2026.
- ZI-MA4-1 targets MAGE-A4, a protein found in many solid cancers, combining TCR precision with NK cell potency.
- The trial will be led by Prof. Fiona Thistlethwaite at The Christie NHS Foundation Trust and Dr. Andrew Furness at The Royal Marsden.
The big picture
Zelluna's approval marks a critical transition to clinical-stage development, positioning it among a select group of companies advancing next-generation cell therapies for solid tumors. The trial's success could validate the company's proprietary TCR-NK platform, addressing key limitations of existing cell therapies. The UK's supportive regulatory framework for advanced therapies provides an efficient pathway for Zelluna to generate early clinical insights.
