|
E.4 | Principal exclusion criteria |
1) a. Received more than 24 hrs of potentially effective systemic (IV/IM or PO) antibiotic therapy prior to randomisation, unless the pathogen was resistant to prior treatment or the patient was a treatment failure (no clinical improvement after 3 days), and/or b. Requires a non-study systemic (IV/IM or PO) antibacterial regimen to which the target pathogen is susceptible. 2) Requirement for concomitant administration of agents containing a cyclodextrin solubilizer such as intravenous Sporanox® (itraconazole) or Vfend® (voriconazole). 3) Patients with baseline QTc >500 msec, congenital long QT syndrome, uncompensated heart failure, uncorrected abnormal K+ or Mg++ blood levels or severe left ventricular hypertrophy. 4) Uncomplicated skin and superficial skin structure infection (e.g. simple abscess, impetiginous lesion, furuncle or superficial cellulitis). 5) Self-limited infection (e.g. isolated folliculitis or other infection that has a high surgical incision cure rate, or furunculosis or carbunculosis that is not associated with a cellulitis at least 2cm in radius). 6) Superinfected eczema, hidradenitis suppurativa or other chronic medical conditions (e.g. atopic dermatitis) where inflammation may be prominent for an extended period even after successful bacterial eradication. 7) Concurrent infections of unremovable prosthetic materials (e.g. permanent cardiac pacemaker battery packs, or joint replacement prosthesis). 8) Concurrent presence of osteomyelitis, endocarditis or other deep site tissue infection other than skin and skin structure infection. 9) Infections due to Gram-positive organism known to be resistant to vancomycin (e.g. vancomycin-resistant enterococcus) or Gram-negative organisms known to be resistant to aztreonam. 10) Burns involving >20% of body surface area or third degree/full-thickness in nature, diabetic foot ulcers, ischemic ulcers/wounds, necrotising fasciitis, gas gangrene, or mediastinitis. 11) Severely neutropenic (absolute neutrophil count < 500 cells/mm3) or anticipated to develop severe neutropenia during the study treatment period due to prior or planned chemotherapy or have HIV with known CD4 count < 100 cells/mm3 during the last 6 months. 12) Known hypersensitivity to or intolerance of study medications or their formulation excipients. 13) a. Female patients of childbearing potential if they are pregnant, nursing or unable to use a highly effective method of birth control during the study and for at least one month following the last dose of study medication. A negative serum pregnancy test must be documented prior to treatment. A highly effective method of birth control is defined as one that results in a low failure rate (i.e. < 1% per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some IUD's, sexual abstinence, or a vasectomised partner. b. Male patients must agree to use medically acceptable birth control for at least three months following last dose of study medication. A vasectomy or a condom used with a spermicide is a medically acceptable birth control method for males. 14) Prior enrollment in a clinical trial of telavancin. 15) Treatment with another investigational medication/device within 30 days of study entry. 16) Patients in shock or who are unlikely to survive through the treatment and evaluation period. 17) Patients unable to comply with the study procedures. 18) Any other condition which, in the opinion of an investigator, would confound or interfere with evaluation of safety or efficacy of the investigational drug, or prevent compliance with the study protocol. |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary efficacy endpoint is the clinical response determined by the investigator at the Test-of-Cure assessment. For purpose of analysis, assessments of "not cured" at End-of-Therapy will be carried forward to Test-of-Cure.
Secondary Efficacy endpoints are: -By-pathogen microbiologic response at Test-of-Cure for MRSA, determined from cultures of the primary infection site. Response will be categorised as "eradicated" or "not eradicated". -By-patient microbiologic response at Test-of-Cure, categorised as "eradicated" or "not eradicated". -Overall therapeutic response at Test-of-Cure, scored as "overall cure" or "failure" according to the patient's combination of clinical response and by-patient microbiologic response.
Tertiary Efficacy endpoints are: -Clinical response at End-of-Therapy -By-pathogen microbiologic response at End-of-Therapy, and Test-of-Cure for each Gram-positive baseline pathogen (other than MRSA at Test-of-Cure) -By-patient microbiologic response at End-of-Therapy -Duration of treatment with study medication -Time to resolution of fever, defined as the first day of the earliest 2-day period during which all temperatures were less than or equal to 38oC -Total signs and symptoms score on days 2-7, at End-of-Therapy, and at Test-of-Cure. The assessments of erythema, flactuance, localised warmth, pain/tenderness and edema/induration will each be scored as 0 (absent) or 1 (present). Wound drainage will be scored as 0 (absent), 1 (non-purulent) or 2 (purulent). Total score will be calculated as the sum of the individual scores and thus can range from 0-7. -Size of primary infection site, defined as the product of length and width on days 2-7 at End-of-Therapy and at Test-of-Cure
Safety endpoints are: -Adverse events -QT and QTc intervals -Laboratory results: hematology (hematocrit, hemoglobin, WBC count including differential count by microscopy with % immature neutrophils (bands), mature neutrophils, and eosinophils and platelet count), Serum Chemistry (potassium, magnesium, blood urea nitrogen (BUN), creatinine, total bilirubin, alkaline phosphatase, LDH, ALT (SPGT), AST (SGOT)) and Urinalysis (presence of blood, bilirubin, urobilinogen, nitrate, leukocytes, microscopic examination of sediment (if dipstick positive) and microalbumin).
Other endpoints are: -Development of resistance to study medication -Pharmacokinetic parameters -Direct medical costs and antibiotic-related length of stay |
