Evaluation of the efficacy and safety of isepamicin compared with amikacin in the treatment of nosocomial pneumonia and septicaemia.

| Abstract |
Isepamicin is a new aminoglycoside antibiotic which possesses greater stability to aminoglycoside-inactivating enzymes compared with other available aminoglycosides. In this prospective, randomised, open trial, the safety and efficacy of intravenous administration of isepamicin was compared with that of intravenous amikacin in seriously ill adults with nosocomial pneumonia or septicaemia. Each study aminoglycoside was administered concurrently with ceftazidime or imipenem. Patients were randomised to receive isepamicin 15 mg/kg once daily, isepamicin 7.5 mg/kg twice daily or amikacin 7.5 mg/kg twice daily. For patients with nosocomial pneumonia, the proportions of patients in the intent-to-treat population (n = 130) who were clinically cured at the end of treatment were similar in each treatment group: 18/44 (41%) isepamicin once daily; 19/45 (42%) isepamicin twice daily; and 17/41 (42%) amikacin. Corresponding results for the efficacy population (n = 58) were: 12/20 (60%) isepamicin once daily; 14/21 (67%) isepamicin twice daily; 9/17 (53%) amikacin. In patients with septicaemia, clinical cure was achieved in 8/10 (80%) patients treated with isepamicin once daily, compared with 8/13 (62%) patients who received isepamicin twice daily, and 7/12 (58%) patients treated with amikacin. For both diagnoses, there were no statistically significant differences between the treatment groups in clinical cure rate. The most commonly isolated target pathogen was Pseudomonas aeruginosa. For both nosocomial pneumonia and septicaemia, the proportion of patients in the intent-to-treat population whose pretreatment valid target pathogens were eliminated was similar in each treatment group. In total, 51 patients (30%) died during study, mostly due to disease progression or complications, or concurrent illness. All three treatment regimens were well tolerated. The proportion of patients experiencing at least one adverse event was 11%, 25% and 9% for isepamicin once daily, isepamicin twice daily and amikacin, respectively. The incidence of ototoxicity and nephrotoxicity was relatively low in both treatment groups.
