EQS-News: First-In-Human Data about the Treatment of Muscle-Invasive Bladder Cancer with Pentixapharm’s Lu177-PentixaTher to be Presented at ASCO-GU 2025

Berlin, Germany, February 13, 2025 – Data from the first-in-human radioligand-therapy for muscle invasive bladder cancer (MIBC) using Pentixapharm’s Lu177-PentixaTher compound will be shown at the American Society of Clinical Oncology’s Genitourinary Cancers Symposium (ASCO-GU 2025) in San Francisco, CA.

The presentation features a case study of a late-stage MIBC patient who was initially treated with three cycles of neoadjuvant combination chemotherapy followed by intravesical administration of Pentixapharm’s radiopharmaceutical that targets the CXCR4 receptor. Imaging with Ga68-PentixaFor PET/CT had revealed intravesical CXCR4 expression prior to therapy, so a subsequent Lu177-PentixaTher instillation was used to target residual tumor cells. Pathological examination after transurethral resection confirmed a complete response, suggesting a potential for bladder preservation.

Instillation therapy in bladder cancer opens the potential for localized treatment with enhanced precision and minimized systemic exposure, thereby reducing the risk of adverse effects.

This early data adds to the growing body of evidence supporting CXCR4 as a therapeutic target across multiple oncology indications. To date, more than 100 patients have been treated with PentixaTher, providing a basis for a Pentixapharm-sponsored clinical development program. In November of last year, a first patient was enrolled in an investigator initiated Phase I/II trial in patients with acute myeloid and lymphoblastic leukemia (AML/ALL) in Nantes, France.
