Philippine Health Research Registry (PHRR)

The Philippine Health Research Registry (PHRR) is a tool for good governance to promote transparency and accountability in health research. PHRR is a publicly accessible database on newly approved health researches. It includes clinical trials and non-clinical studies conducted in the Philippines. The registry is compliant with the World Health Organization (WHO) standard for clinical trials registry.

The PHRR aims to track the kinds of on-going and newly-approved researches to know who funds what kind of project, compel researchers to submit final reports for researches they conducted, avoid duplication of researches, and ensure equal access opportunity for prospective clinical trial participants.

It differs from the HERDIN databases since data entries will be prospective and will be inputted and updated by the researchers themselves. The latter is a searchable bibliographic database of Philippine health information and resources.
