Study of 5 and 10 Days Treatment With Penicillin Against Sore Throat Caused by Streptococci

November 9, 2018 updated by: Ass. Prof. Katarina Hedin

A Randomized Controlled Study of 5 and 10 Days Treatment With Phenoxymethylpenicillin for Pharyngotonsillitis Caused by Streptococcus Group A

The primary objective of the study is to compare the clinical efficacy of 5 days (800 mg x 4) versus 10 days (1000 mg x 3) treatment with phenoxymethylpenicillin (PcV) in adults, adolescents and children with streptococcal tonsillitis. Patients are recruited from 17 primary Health care centres in the south of Sweden. Adult men and women, youth and children ≥ 6 years of age who are visiting the primary Health care for sore throat with suspected tonsillitis and meeting the criteria in accordance with current treatment recommendations for pharyngotonsillitis, ie 3-4 Centor criteria (fever≥ 38.5, tender lymph nodes, coatings of the tonsils and absence of cough) and a positive rapid antigen detection test (RADT) for Group A streptococcus (GAS) will be included in the study. Patients will be randomized to be prescribed PcV of 5 and 10 days. Each patient or guardian fills daily in a short diary including aches, fever, PcV doses, pain relievers, adverse events etc. Five to seven days after last intake of PcV the general practioner make a clinical judgement if the patient has recovered from the pharyngotonsillitis. Questions to be asked are if remaining symptoms or new symptoms of sore throat is present, if adverse events have been noted or of any extra physician visits have been made. Throat swab for semi quantitative cultures of Streptococcus group A, C and G are made at randomization and five to seven days after last intake of PcV. A study nurse will contact the patients one month and three months after the last treatment day for follow-up. If the patient has reconsulted or been hospitalised for a sore throat or possible complication, those patient records will be examined.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Difference between treatment groups in the rate of clinical cure. Clinical cure is defined as clinical judgement by physician and absence of Centor criteria (coating, fever and swollen Large Granular Lymphocyte glands).
5-7 days after discontinuation of treatment

Secondary Outcome Measures

Secondary Outcome Measures
