Change from baseline in SOFA score throughout 28 days

Safety: Number and severity of AEs and SAEs
28 days

Number and severity of AEs and SAEs throughout 28 days follow up period

Assessment of safety by determining the number of participants with any Adverse Events (AE),Serious Adverse Events (SAE) and fatal SAE
28 days follow up

Incidence rates of any Adverse Events (AE), Serious Adverse Events (SAE) and fatal SAE

Treatment-emergent adverse events and Serious adverse events following Allocetra-OTS injection
6 months

The safety and tolerability endpoint evaluates the incidence and severity of complications following intraarticular injection of Allocetra-OTS: * Injection-related reactions occurring during Allocetra-OTS injection, including injection interruption/discontinuation. * Treatment-emergent adverse events following Allocetra-OTS injection. * Treatment-emergent serious adverse events. * Adverse events or serious adverse events related to the use of Allocetra-OTS as an intraarticular injection material. * Safety assessments beyond 1 month following injection will focus on events that are at least possibly related to Allocetra-OTS treatment.

Frequently asked questions about Allocetra-OTS

What is Allocetra-OTS used for?

Allocetra-OTS is an investigational small molecule being studied for sepsis, organ dysfunction syndrome related to sepsis, and knee osteoarthritis. It is being developed by Enlivex Ltd. (ENLV) and is currently in clinical trials, including early phase studies for these conditions.

What does Allocetra-OTS target?

Allocetra-OTS is a small molecule immunomodulator that targets apoptotic cell clearance pathways to restore immune homeostasis. It is designed to reprogram macrophages from a pro-inflammatory to an anti-inflammatory state, which may help in conditions like sepsis and osteoarthritis.

Who makes Allocetra-OTS?

Allocetra-OTS is being developed by Enlivex Ltd., a clinical-stage biopharmaceutical company. The company is publicly traded under the ticker symbol ENLV.

What phase is Allocetra-OTS in?

Allocetra-OTS is in early clinical development. It has completed Phase 1 and Phase 2 trials for sepsis-related organ dysfunction, and an early Phase 1 trial for knee osteoarthritis is active but not recruiting. It is not yet approved by the FDA.

What clinical trials is Allocetra-OTS in?

Allocetra-OTS has been studied in several clinical trials. NCT03925857 was a Phase 1 trial for sepsis-related organ dysfunction. NCT04612413 was a Phase 2 trial for sepsis. NCT06208241 is an early Phase 1 trial for knee osteoarthritis, which is active but not recruiting.

Is Allocetra-OTS the same as any other drug?

Allocetra-OTS is a distinct investigational drug developed by Enlivex. It is not known to be the same as any other approved or investigational product under a different name.
