Operational Highlights Q1 2026:

• First clinical site activated:
  As announced yesterday, Zelluna has activated its first clinical site, The Christie NHS Foundation Trust in the United Kingdom. This marks the transition from clinical preparation to the execution phase of the ZIMA-101 study. Activation of the second clinical site, The Royal Marsden, is expected in the near term.
• CTA approval:
  On 20 February 2026, Zelluna announced that the Medicines and Healthcare products Regulatory Agency (MHRA) and Research Ethics Committee (REC) had approved the Company’s Clinical Trial Application (CTA) for ZIMA-101, a first-in-human Phase 1 clinical trial evaluating ZI-MA4-1, Zelluna’s lead TCR-NK product candidate.
• Collaboration with Etcembly Ltd:
  On 9 March 2026, the Company announced a collaboration with Etcembly Ltd to leverage AI-enabled TCR engineering to develop KKLC1-targeting TCRs.
• Medpace selected as CRO:
  On 11 February 2026, Zelluna announced that it had entered into a clinical partnership with Medpace to support the Phase 1 trial of ZI-MA4-1 (ZIMA-101).

Financial Highlights Q1 2026

• Total operating expenses: MNOK 20.4
• Total loss: MNOK 20.4
• Cash and cash equivalents: MNOK 49.3 as of 31 March 2026
• Financial runway: into Q1 2027

“Q1 2026 marked a major step forward for Zelluna as we moved from regulatory submission into the clinic, following approval of our CTA for ZI-MA4-1 and activation of our first clinical site, announced earlier today. As we progress through 2026, our priorities are clear: dose the first patients in the ZIMA-101 study and execute with discipline as we begin generating clinical data in patients. In parallel, we will continue to selectively advance our pipeline to build on the long-term potential of the TCR-NK platform,” says CEO Namir Hassan.

Outlook

Zelluna enters 2026 with its lead programme, ZI-MA4-1, progressing toward first clinical evaluation in patients following successful GMP manufacturing and CTA approval in the UK. As announced earlier today, the Phase 1 study ZIMA-101 is now underway following activation of the first clinical site. Initial clinical data are expected from mid-2026. The current cash position is expected to support operations into Q1 2027.

The quarterly report and presentation will be made publicly available on the Zelluna website. The Company will host a webcast on 7 May at 08:30 CET, and questions can be submitted throughout the event. The webcast will be archived for replay following the conference call. Link to webcast here.
