A Randomized, Double-Blind, Placebo-Controlled Trial of the Efficacy of Retapamulin as a Topical Decolonizing Agent for Mupirocin Resistant Methicillin Resistant Staphylococcus Aureus (MRSA)

The purpose of this study is to investigate the efficacy of retapamulin to reduce carriage of MRSA via a randomized, double-blind, placebo-controlled clinical study testing retapamulin among patients with confirmed mupirocin-resistant nasal and/or rectal MRSA colonization. The sample size will include 27 subjects in each of the two arms of the study (retapamulin versus placebo) for a total of 54 subjects. Participants who are found to be nasal and/or rectal colonized with MRSA will be randomized to receive either retapamulin or placebo applied nasally and rectally for a total of 5 days. Nasal and rectal swabs will be collected at pre-defined time points during study duration (screening swab, swab one week after completion of topical therapy, swab 4 weeks after completion of topical therapy) to assess MRSA colonization status. The colonization rates of both groups will be assessed via Fisher's Exact Test.

A Study to Evaluate the Feasibility of Microdialysis to Determine Skin Concentrations of Retapamulin in Healthy Volunteers

This feasibility study will allow for the determination of the in vivo recovery and time of dialysis to optimize a future thorough microdialysis study. This is a single session, open label study to evaluate the feasibility of microdialysis for Retapamulin in healthy subjects. Three healthy subjects will be enrolled and complete the study procedures. Subjects will be admitted to the research unit on Day 1 and three microdialysis probes will be placed in the thigh of each subject prior to the start of the microdialysis procedure. After normal saline solution infusion for 30 minutes, a Retapamulin solution will be infused for 90 minutes. Saline perfusion will occur during the washout period. Microdialysis sampling will be done for 30 minutes (during the last 30 minutes of drug perfusion) and dialysate sample collection will continue every 30 minutes for 4 hours. The approximate duration of study including follow-up is 4 days.

Design, Synthesis, and Biological Activity of Thioguanine-Modified Pleuromutilin Derivatives.

Antibiotic overuse has caused the increasingly serious problem of bacterial drug resistance, with numerous marketed antibiotics exhibiting significantly reduced activity against drug-resistant bacteria. Therefore, there is urgent demand for the development of novel antibiotics. Pleuromutilin is a tricyclic diterpene exhibiting antibacterial activity against Gram-positive bacteria and is currently considered the most promising natural antibiotic. In this study, novel pleuromutilin derivatives were designed and synthesized by introducing thioguanine units, and their antibacterial activities against drug-resistant strains were evaluated in vitro and in vivo. Compound 6j was observed to have a rapid bactericidal effect, low cytotoxicity, and potent antibacterial activity. The in vitro results suggest that 6j has a significant therapeutic effect on local infections, and its activity is equal to that of retapamulin, an anti-Staphylococcus aureus pleuromutilin derivative.

Innovative, rapid, high-throughput method for drug repurposing in a pandemic-A case study of SARS-CoV-2 and COVID-19.

Several efforts to repurpose drugs for COVID-19 treatment have largely either failed to identify a suitable agent or agents identified did not translate to clinical use. Reasons that have been suggested to explain the failures include use of inappropriate doses, that are not clinically achievable, in the screening experiments, and the use of inappropriate pre-clinical laboratory surrogates to predict efficacy. In this study, we used an innovative algorithm, that incorporates dissemination and implementation considerations, to identify potential drugs for COVID-19 using iterative computational and wet laboratory methods. The drugs were screened at doses that are known to be achievable in humans. Furthermore, inhibition of viral induced cytopathic effect (CPE) was used as the laboratory surrogate to predict efficacy. Erythromycin, pyridoxine, folic acid and retapamulin were found to inhibit SARS-CoV-2 induced CPE in Vero cells at concentrations that are clinically achievable. Additional studies may be required to further characterize the inhibitions of CPE and the possible mechanisms.

Efficacy of a Novel Antibacterial Agent Exeporfinium Chloride, (XF-73), Against Antibiotic-Resistant Bacteria in Mouse Superficial Skin Infection Models.

Article

Author: Yao, Zhi ; Zhang, Chenrui ; Wang, Song ; Fu, Zheng ; Li, Jinping ; Lu, Rong

Background:

The number of incidences of antimicrobial resistance is rising continually, necessitating new and effective antibacterial drugs. The present study aimed to assess the in vitro and in vivo activity of XF-73 against antibiotic-resistant Staphylococcus aureus (S. aureus) isolates and to investigate the potential mechanism of action of XF-73.

Methods:

The in vitro antibacterial activity of XF-73 and comparator antibacterial drugs, (mupirocin, fusidine, retapamulin, vancomycin, erythromycin, linezolid and daptomycin), against S. aureus (both antibiotic sensitive and resistant strains) was assessed using a broth microdilution method. Two different superficial Staphylococcal skin infection murine models were established to study the in vivo efficacy of XF-73 against antibiotic-resistant strains. The effect of XF-73 on the ultrastructure and cellular morphology of S. aureus was studied using transmission electron microscopy (TEM) and scanning electron microscopy (SEM).

Results:

The MICs (minimum inhibitory concentration) determined by the broth microdilution method for XF-73 demonstrated that the compound had a high potency against S. aureus isolates with varying susceptibility to the study drugs. Also, the antibacterial activity of XF-73 was superior or similar to most of the tested antibacterial drugs. We also found that the XF-73 dermal formulation significantly inhibited S. aureus survival in both the murine skin tape-stripping and suture superficial skin infection models, maintained a consistently high inhibitory capacity against the antibiotic-resistant strains tested and was significantly more effective than mupirocin ointment, a commonly used antibiotic for the treatment of skin infections. The morphological studies using TEM suggest that XF-73 had a rapid (2 minute) bacterial cell wall disruption activity, with longer incubation (10 minute) subsequently causing membrane damage. SEM analysis demonstrated that this cell wall and cell membrane disruption did not lead to disintegration of the plasma membrane, and did not cause bacterial cell lysis.

Conclusion:

Therefore, XF-73 may be an effective drug alternative to combat multi-drug-resistant skin infections in the clinical setting.
