Pediatric Kidney Disease clinical trials

Phase 2/3 Study to Evaluate PK, Safety & Efficacy of INM004 in STEC Positive Pediatric Patients for Prevention of HUS

The investigational medicinal product (IMP), INM004, proposes to neutralize the toxin in the bloodstream to prevent the interaction of the Stx with the specific receptor, by means of a polyclonal antibody to be administered upon the appearance of symptoms (bloody diarrhea) and diagnosis of infection by STEC, thereby preventing the action of the toxin in the body. Thus, the initial hypothesis for examination is for the prevention of the full expression of HUS, based upon presumptive clinical, biochemical, and other biological evidence suggesting a risk of HUS at the time of treatment application. The polyclonal antibody (F(ab')2 fragment) is obtained by processing the serum of equine animals previously immunized against engineered Stx1B and Stx2B immunogens. INM004 could be administered at the earlier stages of STEC disease since subjects with STEC diarrhea are more likely to benefit from Stx neutralizing antibodies before the development of extra-intestinal manifestations and HUS. Neutralizing equine anti-Stx F(ab')2 antibodies (INM004) have the objective of preventing the development of HUS by blocking the circulating toxins in patients infected with STEC. Therefore, INM004 may be used in patients with a clinical manifestation of bloody diarrhea and a positive Stx result in feces. Early interruption of the Stx mediated cascade is expected to prevent the development of HUS, alleviate the severity of the illness, the rate of complications and the incidence/duration of hospitalizations. Therefore, patients in the early phases of the disease will be targeted in this study, ie, children who seek medical care due to diarrhea associated with STEC infection before HUS development.
