Abstract Background Delafloxacin is an investigational anionic fluoroquinolone in development for oral or intravenous administration for the treatment of infections caused by Gram-positive including MRSAGram-negative, atypical and anaerobic organisms.
Objectives To establish the non-inferiority of delafloxacin compared with vancomycin plus aztreonam for the treatment of acute bacterial skin and skin structure infections and to compare the safety of the two antimicrobials.
Results In the ITT analysis set, the objective response was Investigator-assessed cure was similar between the two groups at follow-up Introduction Acute bacterial skin and skin structure infections ABSSSIs have diverse aetiologies due, in part, to varying epidemiological settings, with many different microbes identified as potential causes.
Delafloxacin is chemically distinct from other quinolones in its size, shape and charge profile. These properties result in a highly active agent, particularly against Gram-positive pathogens.
Previous Phase 2 1617 ABSSSI studies demonstrated that delafloxacin is well tolerated and has favourable clinical efficacy compared with tigecycline, 16 linezolid and vancomycin. A written informed consent in compliance with US Title 21 Code of Federal Regulations Part 50, ICH E6 R1 and other applicable regulatory requirements was obtained from each patient or legally authorized representative before entering the study or performing any unusual or non-routine procedure that involved risk to the patient.
A list of institutional review boards used for this study is available. Exclusion criteria were consistent with current guidance and included receipt of systemic antibiotic therapy in the 14 days before enrolment unless one of the following was documented: Further details regarding the eligibility and exclusion criteria are available in Table S1 available as Supplementary data at JAC Online.
Patients were enrolled at 34 study centres in seven countries between April and June and randomized 1: Telephone FU was conducted for all patients 30 days after the last dose of study drug to obtain 28 day all-cause mortality rates, adverse events AEs and use of post-treatment medications.
Clinical failure at this timepoint was defined as any of the following: The EMA-defined primary efficacy measure was the investigator assessment of clinical cure no remaining signs or symptoms at the FU visit in the ITT population. An additional secondary endpoint was investigator-assessed success cure or improved and no further antibiotic needed at the FU visit.
Clinical response at FU and LFU was based on investigator assessment of ABSSSI signs and symptoms and categorized as cure complete resolution of symptoms ; improved near resolution with some remaining symptoms not requiring antibiotic therapy ; failure additional non-study antibiotics or unplanned major surgical intervention required ; or indeterminate.
Patients lost to FU or with indeterminate outcomes and those categorized as improved were considered failures in the primary analysis. Other antibiotic studies in skin infections have defined a successful outcome as resolution or near resolution of signs and symptoms that no longer require antibiotic therapy.
This definition aligns with the definition of success in this study. Microbiological assessments Microbiological response for patients in the microbiological ITT MITT and microbiologically evaluable ME analysis sets was based on results of the baseline and post-baseline cultures through the FU and LFU visits, susceptibility testing and the clinical response assigned by the investigator.
ABSSSI samples were collected before initiation of any rescue therapy and from all clinical failures that had material available for culture. Microbiological response was categorized as documented eradicated baseline pathogen absent in FU cultures ; presumed eradicated no FU material available for culture with a clinical response of success ; documented persisted baseline pathogen present in FU cultures ; or presumed persisted no FU material available for culture with an investigator-assessed response of failure.
Safety and tolerability assessments Safety assessments included all AEs, physical examinations, vital signs, lead ECGs at baseline and if clinically indicated thereafter, and clinical laboratory tests.
AEs were summarized by treatment group and overall for the safety analysis set. Treatment-emergent AEs TEAEs were those that occurred or worsened in severity after administration of the first dose of the study drug through the telephone FU with patients 30 days after the last dose.
Statistical analysis Separate statistical analysis plans were prospectively developed prior to database lock and unblinding for the FDA and the EMA endpoints.
All clinical efficacy outcomes were analysed for the ITT population. Analysis of microbiological outcomes was based on the MITT population.
This is a prospective study that included 17 patients with MRSA-associated recalcitrant CRS. All patients were over 18 years of age, had previously undergone endoscopic sinus surgery and had persistent signs and symptoms of CRS despite maximal medical therapy, . Bacterial Infections of the Circulatory and Lymphatic Systems Although the circulatory system is a closed system, bacteria can enter the bloodstream through several routes. Wounds, animal bites, or other breaks in the skin and mucous membranes can result in the rapid dissemination of bacterial pathogens throughout the body. Approximately 25% to 30% of the population is colonized (when bacteria are present, but not causing an infection) in the nose with staph bacteria and about 1% are colonized with MRSA. Major Symptoms HA-MRSA symptoms vary with location of infection .
Continuous variables were described with descriptive statistics such as mean, standard deviation, median, minimum and maximum while counts and percentages were calculated for categorical data.
The same analysis method was applied to the comparison of microbiological response rates between treatment groups. Among patients enrolled, The safety analysis set included patients who received study drug. The median duration of treatment with delafloxacin was 5 and 5. ITT analysis set included all patients who were randomly assigned to treatment.
CE analysis set included all patients in the ITT population who: SAF, safety; TC, telephone call. Patient demographic and clinical characteristics Baseline characteristics were similar between treatment groups Table 1. The majority of patients were men Bacterial Infections of the Circulatory and Lymphatic Systems Although the circulatory system is a closed system, bacteria can enter the bloodstream through several routes.

any symptoms of the TB disease. The bacilli are inactive, but remain alive in the shows signs and symptoms of the disease. TB disease mostly occurs in the lungs.
A person with TB disease of the lungs (pulmonary TB) usually has. Symptoms of Leukopenia. Blood contains of 5 different kinds of WBCs. They are: Neutrophils, Eosinophils, Basophils, Monocytes and Lymphocytes. Each cell type has different roles in fighting infections. While mild symptoms of the disease are hard to determine, severe symptoms may need immediate medical attention.
Staphylococcus aureus (“staph”) is a common type of bacteria (germ) that is often found on the skin and in the nose of healthy people. It can also grow in wounds or other sites in the body, sometimes causing an infection.
Streptococcus pyogenes (S. pyogenes) is a gram-positive bacterium, known as a Group A Streptococcus, or GAS. It can be found primarily on the skin and in the mucous membranes of its host. The prognosis of MRSA varies according to the severity of the infection and the condition of the patient, which means sometimes it’s fatal.
MRSA, even after treatment, can still stay in the body. Total treatment costs in the base-case were lower for linezolid ($10,).
