Brief Summary:
The aim of this study is to see whether the addition of Clindamycin, a protein inhibiting antibiotic, to the standard antibiotic treatment of limb cellulitis, with Flucloxacillin, results in less tissue damage and a more rapid resolution of both systemic and local features, in a cost-effective manner. This study is a randomised controlled trial comparing Clindamycin with placebo.

Condition or disease Intervention/treatment Phase
Cellulitis Drug: Flucloxacillin and Clindamycin Drug: Flucloxacillin and placebo Phase 4

Detailed Description:

Criteria to be used to assess tissue damage and clinical response:

  1. Fever, tachycardia, neutrophil count, urea and other laboratory parameters at five and ten days post first dose of clindamycin
  2. Limb swelling (by the measurement of limb circumference), skin surface temperature and tissue damage (by the proportion of the limb affected)
  3. Document the duration between initial systemic features and the development of local signs
  4. Examine the effect of the duration between systemic and local features and first dose of flucloxacillin on the subsequent duration and severity of cellulitis
  5. Examine the effect of duration between the first dose of flucloxacillin and the first dose of clindamycin on the subsequent duration and severity of cellulitis
  6. Identify and quantify possible side effects of clindamycin

Arm Intervention/treatment
Placebo Comparator: Flucloxacillin and placebo
Intravenous or oral Flucloxacillin with an oral placebo
 Drug: Flucloxacillin and placebo
Placebo is externally identical to the over-encapsulated clindamycin and is taken four times each day for 2 days
Other Names:
  • Floxapen
  • Fluclomix
  • Ladropen
Active Comparator: Flucloxacillin and Clindamycin
Intravenous or oral Flucloxacillin with oral Clindamycin
 Drug: Flucloxacillin and Clindamycin
Clindamycin dose 300mg four times each day for 2 days, within 48 hours of commencing flucloxacillin. Clindamycin is over-encapsulated and externally identical to placebo.
Other Names:
  • Floxapen
  • Fluclomix
  • Ladropen
  • Dalacin C

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Improvement based on a composite of systemic and local features [ Time Frame: Day 5 ]
    Temperature less than 37.5 degrees centigrade, reduction in limb swelling and reduction in skin temperature


Secondary Outcome Measures :
  1. Decrease in pain [ Time Frame: Day 10 ]
    Assessed using a visual analogue score

  2. Quality of life [ Time Frame: Day 30 ]
    Assessment based on a questionnaire plus return to work or normal activities and absence of increased side-effects.

  3. Physiological recovery [ Time Frame: Day 10 ]
    Resolution of systemic features, composite inflammatory markers and recovery of renal function.
