Adjunctive Clindamycin for the Treatment of Skin and Soft Tissue Infections, a Randomized Controlled Trial

Официальное название

Adjunctive Clindamycin Versus Standard of Care for the Treatment of Skin and Soft Tissue Infections, a Randomized Controlled, Open-label Superiority Phase 4 Trial

Обзор

This is an exploratory study to evaluate the effect of adjunctive clindamycin in the treatment of skin and soft-tissue infections due to Staphylococcus aureus in patients from Sierra Leone. The study hypothesizes that clindamycin, when added to routine treatment, will lead to a more rapid clinical resolution and less frequent recurrences of infection.

Подробное описание

Panton-Valentine Leukokidin and other toxins play an important role in the severity of skin and soft-tissue infections due to Staphylococcus aureus. The inhibition of the protein synthesis could be beneficial, due to the major role of protein-toxins in the pathogenesis of skin and soft tissue infections. Clindamycin has a strong toxin-suppressive activity. Therefore, clindamycin is currently considered as the most-promising adjuvant antimicrobial agent in the treatment of toxin-mediated S. aureus infections. Recurrent infections are common in patients with S. aureus skin and soft-tissue infections. Clindamycin has been reported to reduce S. aureus colonisation, which may in turn reduce the risk for recurrent infections. Clindamycin is an already approved antimicrobial used for a wide range of indications and with a known safety profile.

This study is an investigator-led, investigator-initiated, open-label superiority randomised controlled trial that will be conducted at Masanga Hospital in Sierra Leone. The objectives of this study are to determine the feasibility, efficacy and safety of adjunctive clindamycin therapy (in addition to standard-of-care) compared to standard-of-care alone on clinical treatment outcomes in patients with skin and soft tissue infections due to S. aureus in Sierra Leone. This is a preliminary study, which will include 100 adult participants with skin and soft-tissue infections requiring systemic therapy.
