Scientific titleTo determine the safety, tolerability and systemic absorption of Diethylcarbamazine (DEC) from a "patch" applied locally to the skin for the diagnosis of Onchocerca volvulus infection (Clinical trials of drugs for onchocerciasis) (Ghana)
Study objectivesThe patch based on transdermal drug delivery technology is safe and well tolerated in subjects infected with Onchocerca volvulus and results in recognizable and specific skin reactions.
Ethics approval(s)1. Ghana Health Service Ethical Review Committee (last approval 30/03/2005)
2. World Health Organization (WHO) Ethics Review Committee (last approval date 21/11/2005)
Health condition(s) or problem(s) studiedOnchocerciasis
InterventionTwo types of Diethylcarbamazine (DEC) patches (Onchocerciasis Control Programme [OCP] and Lohmann Therapie-System [LTS]) applied to two groups each of 15 subjects. OCP applied on day one to one iliac crest after overnight fast. After a study and washout period of four days, the LTS patch applied on the other iliac crest and similar blood sampling repeated.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Diethylcarbamazine
Primary outcome measureTo determine the safety, tolerability and potential utility under field conditions for the diagnosis of onchocerciasis of the LTS patch 2 prototype in subjects known to be infected with Onchocerca volvulus. The utility of LTS patch 2 for field use will depend on the ease of preparation, application and readout of the results.
Secondary outcome measures1. To compare the positive reaction rates of the OCP and LTS patches as determined at 24 and 30 hours after application
2. To determine the underlying pathology of the skin reactions from the histopathology of skin punch biopsies taken from selected subjects
Overall study start date12/06/2003
Completion date01/08/2006
