• Global CRO to support execution of ZIMA-101 study with world's first MAGE-A4-targeting TCR-NK cell therapy product
• Partnership follows submission of the Clinical Trial Application (CTA) to the MHRA

Oslo, Norway – 11 February 2026 – Zelluna (OSE: ZLNA), a company pioneering allogeneic "off-the-shelf" T Cell Receptor-based Natural Killer (TCR-NK) cell therapies for the treatment of solid cancers, today announced a clinical partnership with Medpace, a leading global Contract Research Organization (CRO), to support the first clinical trial of ZI-MA4-1 (ZIMA-101), Zelluna's lead product candidate.

Highlights:

• Medpace selected as clinical partner for ZI-MA4-1 (ZIMA-101) first-in-human Phase 1 study
• Comprehensive CRO services to support Zelluna's transition to clinical-stage company
• Study to evaluate safety and early efficacy in patients with advanced solid cancers
• Clinical data expected to emerge from mid-2026
• Marks first clinical evaluation of Zelluna's proprietary TCR-NK platform
  
  

The partnership with Medpace marks a critical step in Zelluna's transition from preclinical to clinical stage. Medpace will provide comprehensive clinical development services including clinical operations and trial management, regulatory support, data management and analysis, as well as pharmacovigilance. This gives Zelluna access to experienced infrastructure and expertise necessary to execute a complex cell therapy trial in accordance with international standards.

ZI-MA4-1 is a novel cell therapy that combines two powerful mechanisms to fight cancer: precise tumour recognition via T cell receptors (TCRs) that identify MAGE-A4, a protein found in many solid cancers, and broad and potent killing ability from Natural Killer (NK) cells that can eliminate cancer cells through multiple pathways simultaneously.

The planned Phase 1 study will evaluate safety, tolerability, and early signs of clinical activity in patients with advanced solid cancers including lung cancer, ovarian cancer, head and neck cancer, and sarcomas. The study represents the first clinical validation of Zelluna's proprietary TCR-NK platform, and initial clinical data is expected to emerge from mid-2026.

"Selecting Medpace as our clinical partner reflects a deliberate and strategic choice as we transition into clinical stage," said Namir Hassan, CEO of Zelluna. "Medpace brings deep oncology expertise and a strong track record in early-phase development, including cell therapies. This first study will not only advance ZI-MA4-1, but also provide us with clinical insights into the broader potential of our TCR-NK platform."

"Zelluna's TCR-NK platform represents a novel and innovative approach to addressing key challenges in cell therapy for solid tumors," said Lyon Gleich, MD, Senior Vice President, Medical Department at Medpace. "We look forward to partnering with the Zelluna team to support the efficient and rigorous execution of the ZI-MA4-1 first-in-human study."

Zelluna plans to initiate the first clinical trial of ZI-MA4-1 subject to regulatory approval (CTA approval), marking a key milestone in the clinical development of the company's off-the-shelf TCR-NK cell therapy portfolio.
