About Reltecimod

Reltecimod is a rationally designed peptide that binds to the CD28 co-stimulatory receptor that modulates the host’s immune response to enhances the resolution of organ failure and other morbidities in condition associated with a severe acute inflammatory response. Reltecimod received Orphan Drug status from the FDA and EMA as well as Fast Track designation for the NSTI indication.

About Necrotizing Soft Tissue Infections (NSTI)

NSTI is a rapidly progressing condition that often result in significant tissue destruction and systemic disease leading to multiple organ failure and death. NSTI are rare, with an estimated 30,000 patients annually in the US. Currently, there are no approved treatments for NSTI. The standard of care includes prompt and repeated surgical debridement, aggressive resuscitation and physiologic support.

About Acute Kidney Injury (AKI)

Acute Kidney Injury (AKI) involves inflammatory processes in the kidney which can lead to permanent reduction of kidney function and is also associated with an increased risk of death, extended hospitalization, and increased medical cost. There are currently no approved therapies to treat AKI and the only treatment options are dialysis and supportive care.

The REAKT (Reltecimod Efficacy for Acute Kidney Injury Trial) is an ongoing randomized, placebo-controlled study, that is enrolling patients with abdominal sepsis and severe AKI at approximately 70 centers in the US and Europe. Patients receive Reltecimod or placebo, administered as a single dose after the diagnosis of AKI, in addition to standard of care treatment. The primary endpoint is a composite end point assessing the durable loss of kidney function in patients.
