Lytix Biopharma Q2/H1 2025: Preparing for a milestonerich second half with advancing clinical programs and strengthened organization

Oslo, Norway, August 28, 2025 – Lytix Biopharma AS, a clinical-stage immuno-oncology company, today announced its results for the second quarter and first half of 2025.

The first half of the year has been a period of steady clinical progress and preparation. Lytix advanced across clinical, regulatory and organizational priorities, building a stronger foundation for the decisive period ahead.

• Over the past years, we have validated Lytix technology across several cancer types and indications with strong results in a variety of patient populations. Our technology has demonstrated proof-of-concept across various skin cancers, highlighting a significant and urgent need for new treatment alternatives. The gap in today's treatment options is positioning Lytix and our drug candidates at the forefront for cancer treatment of tomorrow, said Dr. Øystein Rekdal, CEO of Lytix Biopharma.

At the center of this progress is Ruxotemitide (formerly LTX-315). The program has matured with the assignment of its international nonproprietary name (INN), a successful End-of-Phase II FDA meeting for basal cell carcinoma through partner Verrica, and completion of patient treatment in the ATLAS-IT-05 trial in advanced melanoma. In parallel, enrollment is progressing in the NeoLIPA study in early-stage melanoma, with interim results expected in November 2025.

These clinical steps are complemented by a strengthened leadership team and board, reflecting Lytix's transition from clinical exploration toward late-stage development, partnering, and future commercialization.

• We are moving step by step toward patients. With the completion of our advanced melanoma trial and progress in early-stage melanoma, Ruxotemitide is transitioning into earlier disease settings where therapeutic potential is greater. Alongside our partner Verrica's preparations for Phase III in basal cell carcinoma, the coming months will be a milestone-rich period for Lytix, said Rekdal.

H1 2025 highlights and developments

• Licensing partner Verrica Pharmaceuticals had a successful end-of-phase II FDA meeting for Ruxotemitide in basal cell carcinoma; alignment on advancing to Phase III

• Cash and short-term investments totaled NOK 100.3 million as of June 30, 2025
• ATLAS-IT-05 accruals reduced by NOK 10.2 million due to lower trial drug costs (non-cash adjustment)
