Frequently asked questions about Allocetra

What is Allocetra?

Allocetra is an investigational small molecule therapy developed by Enlivex Ltd. It is being studied in knee osteoarthritis and in sepsis-related organ dysfunction. It is not approved for any indication and remains in clinical development, with trials conducted in the United States, Denmark, Poland, Israel, Moldova, Belgium, France, the Netherlands, and Spain.

What is Allocetra used for in knee osteoarthritis?

Allocetra is being studied as an intra-articular injection for primary knee osteoarthritis, including end-stage disease. Trials have enrolled adults with knee osteoarthritis, with minimum ages ranging from 18 to 64 years depending on the study. The program includes both Phase 1 and Phase 2 trials, and the osteoarthritis indication remains investigational.

Who makes Allocetra?

Allocetra is developed by Enlivex Ltd., which trades under the ticker ENLV. The company sponsors the clinical program, including the intra-articular knee osteoarthritis studies and the completed Phase 2 sepsis trial. Allocetra-OTS is the name used for the same asset in several of these studies.

What phase is Allocetra in?

Allocetra is in clinical development across Phase 1 and Phase 2 studies. The knee osteoarthritis program includes an active Phase 2 trial, a Phase 1 trial, and an early Phase 1 safety study. A Phase 2 sepsis trial has been completed. Allocetra is investigational and has not been approved by the FDA.

What clinical trials is Allocetra in?

Allocetra trials include NCT07580716, a recruiting Phase 2 study of intra-articular Allocetra in primary knee osteoarthritis with 182 patients; NCT06233474, an active Phase 1 knee osteoarthritis study; NCT06208241, an early Phase 1 safety study in end-stage knee osteoarthritis; and NCT04612413, a completed Phase 2 sepsis trial.

Is Allocetra the same as Allocetra-OTS?

Yes, Allocetra-OTS is an alternative name for Allocetra. Enlivex Ltd. uses the Allocetra-OTS designation in several studies, including the early Phase 1 end-stage knee osteoarthritis safety trial and the completed Phase 2 sepsis trial in adults with organ failure. Both names refer to the same investigational asset.
