TELI TAD - Telithromycin in Tonsillitis in Adolescents and Adults

Official Title: “Multinational, Randomized, Double Blind, Comparative Study to Evaluate the Efficacy and Safety of 5 Days Telithromycin 800 mg od Versus 10 Days Penicillin V 500 mg Tid in Adolescent and Adult Subjects Equal to or Over 13 Years With Streptococcus Pyogenes Tonsillitis/Pharyngitis”

This is a multinational, randomized (1:1), double blind, comparator-controlled, 2 parallel treatment group study in subjects equal to or over 13 years of age, with Streptococcus pyogenes tonsillitis/pharyngitis (T/P). Each subject will receive either telithromycin, 400 mg over-encapsulated tablets, 800 mg once daily for 5 days or penicillin V 250 mg over-encapsulated tablets, 500 mg three times daily for 10days. Matching placebo capsules will be dispensed to maintain the blind between the treatment groups.A positive rapid identification test for streptococcal Group A antigen will be required for all subjects at Visit 1 (Day 1) for entry into the study. Throat swab specimens for bacterial culture, identification, and antibiotic-susceptibility testing will be taken at Visits 1, 3 and 4.

Intervention(s) in this Clinical Trial

• Drug: Telithromycin
• Drug: Penicillin

Primary Measures

• To compare the bacteriologic efficacy of 5-days of telithromycin to 10-days of penicillin V insubjects at the posttherapy/test-of-cure (TOC) visit in the per protocol population.

Secondary Measures

• To compare the bacteriologic efficacy of 5-days of telithromycin to 10-days of penicillin V insubjects at the posttherapy/test-of-cure (TOC) visit andlate posttherapy visit (Visit 4) in the bacteriologic modified intent to treat population.

Inclusion Criteria:

• History of rheumatic heart disease;
• Known congenital prolonged QT syndrome;
• Known or suspected uncorrected hypokalemia (≤3 mmol/L [mEq/L) or hypomagnesemia or bradycardia (<50 bpm);
• Known impaired renal function, as shown by creatinine clearance ≤25 mL/min
• Myasthenia gravis;
• History of hypersensitivity or intolerance to macrolides, penicillins, or cephalosporins;
• Previous enrollment in this study or previous treatment with telithromycin;
• Children of the investigator or subinvestigator, research assistant, pharmacist, study coordinator, other staff, or relative thereof directly involved in the conduct of the protocol.
• Is currently being treated with systemic antibacterials or has been treated with systemic antibacterials within 14 days prior to enrollment;
• Has been treated with any investigational medication within the last 30 days;
• Has been treated with rifampicin, phenytoin, carbamazepine, or St. John's wort within the last 2 weeks.
