Basel, Switzerland – Oct 2, 2024, Alentis Therapeutics (“Alentis”), the clinical-stage biotechnology company developing treatments for Claudin-1 positive (CLDN1+) tumors and organ fibrosis, announced today that the U.S. Food & Drug Administration (FDA) cleared an IND application for ALE.P02, an anti-CLDN1 ADC with a tubulin inhibitor payload. A Phase 1/2 clinical trial in patients with CLDN1+ squamous tumors is expected to start during the first quarter of 2025.

“ADCs have shown great potential in the treatment of cancer,” Luigi Manenti, Chief Medical Officer of Alentis. “Squamous cancers originating in the head and neck, cervix, esophagus and lung are characterized by high CLDN1 expression, and ALE.P02 provides a first-in-class opportunity for these patients who need new therapies after first-line treatment fails.“

“Anti-CLDN1 ADCs are exciting because they address the urgent need for novel targets in the ADC space,” added Tony Mok, Professor of Clinical Oncology at the Chinese University of Hong Kong. “ALE.P02 is particularly promising for squamous cancers, including HNSCC and NSCLC, where CLDN1 is often overexpressed. The unmet medical need in these indications is significant, and I look forward to the results of the Phase 1/2 study.”

Dr. Roberto Iacone, Chief Executive Officer of Alentis said, “ALE.P02, entering the clinic, marks a significant advancement in our oncology pipeline. We can maximize our development plan by leveraging insights from human clinical trials of lixudebart (ALE.F02), used as the backbone antibody for Alentis’ ADCs.”

Dr. Iacone added, “For our second ADC program, ALE.P03, with its topoisomerase I inhibitor payload, we plan to initiate a first-in-human clinical trial in 2025.”

About ALE.P02
ALE.P02 is a first-in-class ADC designed by linking a tubulin inhibitor, a potent cancer drug, to our antibody that specifically targets a unique CLDN1 epitope exposed on cancer cells. This combination could be a powerful new tool to fight the many squamous cancers that overexpress CLDN1 with less toxicity than traditional cancer drugs.
