Become a volunteer in clinical studies

Taking part in a clinical study is voluntary. In a minute you can check whether you meet the general conditions, then leave your phone number: the coordinator will tell you which studies are currently enrolling. The doctor will explain everything else in person before you sign the consent.

Could you take part? Check in a minute

A guide to the general conditions for healthy volunteers (the EAEU Bioequivalence Rules and Federal Law No. 61-FZ). Your answers are not sent anywhere: the check runs in your browser.

This is a guide, not a medical opinion or a questionnaire: you discuss diagnoses with the doctor in person. The final decision is made by the doctor under the protocol of a specific study.

How to sign up in three steps

  1. Check the conditions. Use the self-check above: it takes a minute and your answers are not sent anywhere. The conditions are described in more detail on the page “Who can take part”.
  2. Leave your phone number or call. Fill in the short form or call +7 (499) 346-21-15. The coordinator will tell you which studies are currently enrolling. We do not collect a health questionnaire on the website: the doctor will discuss this with you in person.
  3. Talk to the doctor. At the talk, the study doctor explains the purpose of the study, the procedures, the risks and the benefits. Whether to take part is your decision, after everything has been explained. See how participation works, step by step. You can also prepare for the talk.

You can see which studies are enrolling now on the page “Studies enrolling volunteers”.

Payments and compensation to study participants: how it works

The terms of payments to participants are approved by the ethics committee and stated in the informed consent of the particular study: the methods, the amount and the procedure. The amount is set in proportion to participation and does not depend solely on whether the protocol is completed.

Who can become a volunteer in a clinical study

There is no single list: the conditions of participation are set by the protocol of each study, and the investigator physician decides. Bioequivalence studies use healthy volunteers aged 18 or over; the law bars several groups, for example pregnant and breastfeeding women.
