Clinical Trials for NHPs (CTA)

Most Natural Health Product licenses can be obtained through product license application submissions providing safety and efficacy data based on the medicinal ingredients in the formula submitted.

Companies may, however, have a human clinical trial conducted for several reasons:

  • To demonstrate an ingredient at different dosage levels than those indicated in peer reviewed journals;
  • When no studies have been previously conducted, published or unpublished;
  • When new conditions not captured on the product label are seeking evidence for support.

Clinical studies can vary in complexity, from a meta-analysis of studies conducted to a multi-center, double-blind, placebo-controlled human clinical trial.

For such a study to be acceptable for a natural health product, it is advisable to follow the protocol for clinical trials as outlined by the NHPD. The clinical trial format should follow the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) and Good Clinical Practice (GCP) guidelines.
