EQS-News: Pentixapharm Signs Contract Manufacturing Agreement for Yttrium-90-based PentixaTher with Eckert & Ziegler SE

Berlin, Germany, April 24, 2025 – Pentixapharm, a clinical-stage biopharmaceutical company, today announced the signing of a manufacturing agreement with Eckert & Ziegler Radiopharma GmbH (EZR), a 100% subsidiary of Eckert & Ziegler SE. Under the terms of the agreement, EZR will produce and distribute patient-specific doses of Y90-PentixaTher, Pentixapharm’s lead CXCR4-targeting radiotherapeutic, for use in clinical trials.

Y90-PentixaTher is a radiolabeled peptide designed to deliver targeted radiation to cancer cells that overexpress the CXCR4 receptor - commonly found in malignancies such as acute myeloid leukemia, lymphoma, myeloma and various solid tumors. The compound is labeled with Yttrium-90, a high-energy beta emitting radionuclide with deeper tissue penetration and a shorter physical half-life (64 hours) compared to Lutetium-177, enabling effective tumor irradiation with controlled therapeutic duration. Used alongside the radiodiagnostic Ga68-PentixaFor, it supports a theranostic approach that allows physicians to visualize the disease before and after treatment.

As part of the newly signed agreement, EZR will manufacture Y90-PentixaTher under GMP conditions and manage the direct shipment of individual patient doses to trial sites. The agreement is limited to the clinical development phase and does not extend to commercial-scale manufacturing. Pentixapharm retains full strategic flexibility under this agreement to determine its future development and commercial supply.

“With this agreement, we are proud to support the advancement of Pentixapharm’s clinical oncology program,” said Dr. Harald Hasselmann, CEO of Eckert & Ziegler SE (EZAG). “Reliable access to high-quality radioisotopes is critical for the development of next-generation radiopharmaceuticals and we are pleased to contribute our manufacturing excellence to accelerate the delivery of innovative cancer therapies.”

"Securing a reliable Y90-PentixaTher GMP production is a significant milestone for Pentixapharm," said Dr. Dirk Pleimes, CEO of Pentixapharm AG. "This agreement marks a critical step as we advance our targeted radiopharmaceutical therapies toward late-stage development."
