Würzburg, Bavaria, 8 June 2023. PentixaPharm GmbH, a developer of innovative radiopharmaceuticals fully owned by Eckert & Ziegler Strahlen- und Medizintechnik AG (ISIN DE0005659700; TecDax) has received the approval from the German Federal Institute for Drugs and Medical Devices (BfArM) to start PTT101, its open-label dose escalation study to evaluate the safety, tolerability, biodistribution and efficacy of PentixaTher. The Yttrium-90 labelled CXCR4-compound PentixaTher will be tested as a radiotherapeutic against recurrent or refractory primary or isolated secondary central nervous system lymphoma.

The phase I/II, dose-finding study will be conducted at the University Hospital in Essen, North Rhine Westphalia, Germany. “After showing up to 90% of CNS lymphoma patients overexpressing the target CXCR4 with the Ga68-labeled tracer PentixaFor in CNS lymphoma patients, we are happy to test now the therapeutic impact when attacking CXCR-4 with [⁹⁰Y]Y-PentixaTher (yttrium (⁹⁰Y) anditixafortide). The study will start after getting final endorsement from the German Radiation Safety Department (BfS),“ commented Dr. Hakim Bouterfa, Chief Medical Officer at Eckert & Ziegler.

In addition, radiolabelled PentixaTher has shown outstanding results under named-patient programs in patients with T-cell lymphoma as conducted at the University Hospital Würzburg (DOI: 10.2967/jnumed.122.264207) (1).
