BOSTON and LONDON, August 19, 2024 (GLOBE NEWSWIRE) - Akari Therapeutics, Plc (Nasdaq: AKTX), an innovative biotechnology company developing advanced therapies for autoimmune and inflammatory diseases, has reported financial results for the second quarter ended June 30, 2024 as well as recent company highlights.

"Moving into my fourth month as Interim CEO of Akari, we continue to make progress on multiple fronts. We prioritized our PAS-nomacopan geographic atrophy development program, and I am pleased to report we are making steady progress. In July we received positive and constructive Pre-IND (PIND) feedback from the US FDA and based on the feedback, we plan on filing an IND application in 2025 for our Phase 1 clinical studies of PAS-nomacopan in geographic atrophy. In addition, in support of this IND application, I am happy to share that we have released our first full-scale batch of drug substance under applicable Good Manufacturing Practice (GMP) conditions, which will be suitable for clinical use. This manufacturing has been supported by our manufacturing partner, Wacker Biotech GmbH. Sufficient clinical material has been produced to support both the final IND-enabling studies and initial clinical development in geographic atrophy (GA). I would like to thank the FDA as well as Dr. Miles Nunn and his development team at Akari, who have worked tirelessly to advance the development of PAS-nomacopan into the clinic," stated Dr. Samir R. Patel, Interim CEO of Akari.

"Our merger with Peak Bio continues to progress and we remain on track for a fourth quarter closing," continued Dr. Patel. "We continue to explore licensing and partnership opportunities for both nomacopan and PAS-nomacopan."
