Overview of the efficacy of isepamicin in the adult core clinical trial programme.
The efficacy of once-daily administration of isepamicin in hospitalized adult patients has been assessed in a multinational clinical trails programme. Following a small phase II programme, the phase III programmed assessed four main indications: lower respiratory tract infections (including nosocomial pneumonia), urinary tract, intra-abdominal and skin and soft tissue infections. The phase III trials were open, prospective, multicentre studies in which 1443 patients were randomised to receive either isepamicin (n = 1005) or amikacin (n = 438). The daily dose of isepamicin was dependent on the severity of infection (8 or 15 mg/kg once daily) while all patients received amikacin 7.5 mg/kg twice daily. A study of patients with nosocomial pneumonia had an additional treatment arm of isepamicin 7.5 mg/kg twice daily. The aminoglycosides were combined with other antimicrobial agents in accordance with current clinical practice depending on the site and severity of the infection and the type of organism isolated. Overall, clinical cure or improvement response rates of the isepamicin and amikacin regimens were comparable, ranging from 76-95% in the intent-to-treat population. Lower clinical response rates (62-63%) was observed in severely ill patients with nosocomial pneumonia in both the isepamicin and amikacin treatment groups. In the efficacy population, organism elimination rates of 90% were achieved with isepamicin and amikacin. Therefore, in adult patients with a wide range of infections requiring aminoglycoside therapy, once-daily dosing with isepamicin is as effective as twice- daily dosing with amikacin.
