Alentis Therapeutics Announces First Patient Dosed in Phase 1b “FEGATO-01” Clinical Trial of ALE.F02 for the Treatment of Liver Fibrosis 

The Study Evaluates the Pharmacokinetics of ALE.F02 in Advanced Liver Fibrosis Patients

Basel, Switzerland – 13 July 2023,  Alentis  Therapeutics (“Alentis”), a clinical-stage biotechnology company developing treatments for Claudin-1 positive (CLDN1+) tumors and organ fibrosis, announced today that the first patient with liver fibrosis has been dosed in the Phase 1b “FEGATO-01” clinical trial of ALE.F02, a CLDN1 targeting investigational antibody for the treatment of liver, kidney, and lung fibrosis.

“ALE.F02 can potentially reverse advanced liver fibrosis,” said Dr. Luigi Manenti, Chief Medical Officer of Alentis. “We have a truly differentiated approach of inhibiting pathologically overexpressed CLDN1 to transform the course of disease in liver, kidney, and lung fibrosis.”

Dr. Roberto Iacone, Chief Executive Officer of Alentis added, “After the completion of a Phase 1 study of ALE.F02 in healthy volunteers earlier this year, I am excited the program now advances to the next phase of development in patients. It is a hopeful moment for the fibrosis community as our technology may address the high unmet medical need of people living with organ fibrosis.”

About the Phase 1b ‘FEGATO-01’ clinical trial
This double-blind placebo-controlled randomized trial is designed to study how the body processes ALE.F02 (pharmacokinetics) in 34 patients with advanced liver fibrosis. Besides primary endpoint PK, secondary endpoints in the trial include safety, pharmacodynamics, target engagement, and further understanding of CLDN1 biology. NCT05939947 

About ALE.F02
ALE.F02 is a first-in-class monoclonal antibody developed to specifically target a unique CLDN1 epitope exposed in fibrotic tissue in order to reverse the disease. ALE.F02 is an investigational antibody that was observed to be well tolerated, with no serious safety concerns, during Phase 1 single- and multiple-ascending dose studies in healthy volunteers.
