Alentis Therapeutics – a clinical-stage biotechnology company developing treatments for Claudin-1 positive (CLDN1+) tumors and organ fibrosis – announced that it has raised $181.4 million in Series D financing, supported by a syndicate of top-tier biotech investors. The funding will support Alentis to develop a deep pipeline of CLDN1 targeted medicines for solid tumors. This funding round was led by OrbiMed with co-leads Novo Holdings and Jeito Capital. New investors Frazier Life Sciences, Longitude Capital, Catalio Capital, Piper Heartland Healthcare Capital and Avego Bioscience Capital participated in the round. And significant backing was also received from existing investor RA Capital Management, along with support from Morningside Venture Investments, BB Pureos, Bpifrance through its InnoBio 2 fund, and other early institutional investors, all of whom have been instrumental to Alentis’ development path.

The proceeds of the funding will be used to conduct Phase 1/2 clinical trials of two first-in-class ADCs targeting CLDN1, ALE.P02 and ALE.P03, further development of the pipeline, and general corporate purposes. And the FDA recently cleared an IND application for a Phase 1/2 clinical trial of ALE.P02 (with a tubulin inhibitor) in advanced or metastatic CLDN1+ squamous solid tumors.

This clinical trial is expected to start in Q1 of 2025. For ALE.P03 (with a topoisomerase I inhibitor), a first-in-human trial in patients with CLDN1+ tumors is planned to start next year.

As part of the funding, three new Board Members will join the Alentis Board of Directors, further strengthening the business, science and drug development expertise at the Board level.

— Dina Chaya, Partner at OrbiMed, has 20+ years of experience in healthcare investments, specializing in biopharma and medical technology.

— Anna Chen, Principal at Frazier Life Sciences, where she has been involved with investing in and building many of Frazier’s biopharmaceutical portfolio companies over the past 7 years.

— Brian Liu, Managing Director at Longitude Capital, brings 10+ years of biopharma consulting and investing experience, focusing on transformative healthcare innovation.
