Previous studies showed efficacy in dose ranges of mostly 5 to 20 mg Policosanol per day. As nearly all previous studies have been performed in Latin America it cannot be excluded that either ethnic or nutritional factors contribute to the dose found to be optimal in this region. This circumstance as well as the requirement to meet the ICH Guideline “Ethnic Factors in the Acceptability of Foreign Clinical Data” make further studies, i.e. a dose-finding clinical trial, an efficacy clinical trial in European patients and a long-term tolerability clinical trial in Caucasian patients necessary.
