Ceftobiprol v léčbě pacientů s akutními bakteriálními infekcemi kůže a kožní struktury

17. září 2026 aktualizováno: Basilea Pharmaceutica

Randomizovaná, dvojitě zaslepená, multicentrická studie ke stanovení bezpečnosti a účinnosti ceftobiprolu medocaril ve srovnání s vancomycinem plus aztreonam při léčbě akutních bakteriálních infekcí kůže a kožní struktury

This was a randomized, double-blind, active-controlled, parallel-group, multicenter study in adult hospitalized patients to establish the safety and efficacy of ceftobiprole medocaril compared with vancomycin plus aztreonam in the treatment of acute bacterial skin and skin structure infections (ABSSSIs).

Detailní popis

This was a randomized, double-blind, active-controlled, parallel-group, multicenter study in adult hospitalized patients with ABSSSIs. Randomization was stratified by study site and type of ABSSSI (with major cutaneous abscess comprising ≤ 30% of the Intent-to-Treat [ITT] population).

Primary endpoint for FDA: Early clinical response based on the percent reduction in lesion size at 48-72 hours compared to baseline in patients who did not receive rescue therapy and were alive, in the ITT population.

Primary endpoint for EMA: Investigator-assessed clinical success at the test-of-cure (TOC) visit 15-22 days after randomization, in the co-primary ITT and Clinically Evaluable (CE) populations.

Women who are of childbearing potential and unwilling to use an acceptable method of birth control during the study: female sterilization (bilateral tubal occlusion or oophorectomy, or hysterectomy) or male partner vasectomy; intrauterine device (IUD); combined (estrogen and progesterone containing) hormonal contraception (oral, vaginal ring, or transdermal patch) with an ethinylestradiol dose of at least 30 µg, plus use of male condoms (preferably with spermicides), female condoms, a female diaphragm or a cervical cap; or total sexual abstinence.

    Women are not considered to be of childbearing potential if they are either ≥ 1 year post-menopausal (where menopause is defined as at least 12 months of amenorrhea), or have a serum follicle stimulating hormone (FSH) measurement consistent with post-menopausal status according to local laboratory thresholds. An FSH measurement at Screening is to be obtained for post-menopausal females aged < 50 years, or for those aged ≥ 50 years who have been post-menopausal for < 2 years.

Experimentální: ceftobiprole medocaril

Patients treated with ceftobiprole medocaril 500 mg q8h (with dose adjustment for renal impairment).

ceftobiprole 500 mg was to be administered every 8 hours as a 2-hour IV infusion (with dose adjustment for renal impairment). The treatment duration was for a minimum of 5 days and a maximum of 10 days. Treatment could be extended up to 14 days if in the investigator's opinion this was required, and the extension was approved by the sponsor's medical monitor.

Ostatní jména:
  • ceftobiprol
Aktivní komparátor: vancomycin+aztreonam

Patients treated with vancomycin 1000 mg (or 15 mg/kg) q12h plus aztreonam 1000 mg q12h (both with dose adjustment for renal impairment).

Vancomycin 1000 mg (or 15 mg/kg) was to be administered every 12 hours (with dose adjustment for renal impairment) as 2-hour IV infusion. Vancomycin dose adjustment for morbidly obese and hypermetabolic patients was to be done according to local standard of care. When locally available, vancomycin trough testing (VTT) might have been used by the unblinded pharmacist or delegate to adjust the vancomycin dose. The treatment duration was for a minimum of 5 days and a maximum of 10 days. Treatment could be extended up to 14 days if in the investigator's opinion this was required, and the extension was approved by the sponsor's medical monitor.

Aztreonam 1000 mg was to be administered as a 0.5-hour IV infusion every 12 hours. If CLCR was < 30 mL/min (i.e., severe renal impairment), the aztreonam dosage regimen was to be adjusted. The requirement to continue aztreonam therapy beyond Day 3 was to be reassessed at the 72-hour study visit.
