Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Tonsillitis; Pharyngitis

Intervention: Telithromycin (HMR3647) (Drug); Penicillin (Drug)

Phase: Phase 3

Status: Terminated

Sponsored by: Sanofi


This is a multinational, randomized (1: 1), double blind, double dummy, comparator-controlled, 2 parallel treatment group study in subjects from 6 months to < 13 years of age, with Streptococcus pyogenes tonsillitis/pharyngitis (T/P).Each subject will receive either telithromycin 25 mg/kg once daily for 5 days or penicillin V, 13. 3 mg/kg three times daily for 10 days. Matching placebo for telithromycin and penicillin V will also be dispensed for 5 and 10 days respectively, to provide blinding to the different treatment regimens. 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.

Clinical Details

Official title: Multinational, Randomized, Double-Blind, Double Dummy, Comparative Study to Evaluate the Efficacy and Safety of 5 Days Telithromycin 25mg/kg od Versus 10 Days Penicillin V 13.3 mg/kg Tid in Children 6 Months to Less Than 13 Years With Streptococcus Pyogenes Tonsillitis/Pharyngitis

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: To compare the bacteriologic efficacy of 5-days of telithromycin to 10-days of penicillin V in subjects at the posttherapy/test-of-cure (TOC) visit in the per protocol population

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


Minimum age: 6 Months. Maximum age: 13 Years. Gender(s): Both.

- 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
