Important Information - CTRI Registration

For postgraduate thesis: The concerned guide of postgraduate thesis should account as the PI while registering.

Your Trail will be considered as incomplete if the scanned Ethical Committee Letter is not enclosed.

The study title should be easy to understand using simple words and abbreviations.

“Secondary id” is any number associated with the trial, for example, the number of an already registered multi-centric trial in another registry (Universal Trial Number UTN) or protocol number. It is not a mandatory section.

If the study is an academic exercise (investigator-initiated trials), the source of monetary/material support should be acknowledged as “Institutional”

Primary sponsor may or may not be the funding agency, but it is responsible for initiation, conduct, and management of the study. e.g., the investigator in an investigator-initiated trial can be the primary sponsor.

It is the responsibility of the sponsor to ascertain whether DCGI approval is required or not.

International Non-proprietary Name (INN) is to be used if possible (not brand/trade names). For an unregistered drug, the generic name, chemical name, or company serial number is acceptable. For each intervention, description of other intervention details should be provided (e.g., dose, duration, mode of administration).

Most importantly, registering once is not the end of the exercise and data (e.g., recruitment status, results, adverse events) are to be updated in the registry time to time as the trial progresses.
