What happens if I don't pass the screening health check? Will I still receive any compensation?
If you don't pass the health check for screening, you'll still get paid for the screening. But sometimes, you'll only get money to cover travel from the nearest station to the clinic and back.
  • This might happen if your BMI isn't in the right range.
  • It can also happen if you choose to leave before signing the informed consent document.
  • If your answers on the questionnaire make it clear you can't take part, you'll also only get the travel money.
  • The same is true if you didn't answer the online questionnaire correctly and that affects whether you can take part.
What actually happens in the screening session?

The screening session is a comprehensive process designed to gather all the necessary information about participants and ensure their suitability for the trial. It consists of several stages:

  1. Check-In, Questionnaire, and Agreement: During the check-in stage, you'll be registered into the system and your details verified. This will be followed by a questionnaire to understand your health background and lifestyle. Finally, you'll go through an agreement document that will detail the terms and conditions of the trial. This process typically takes between 30 minutes to 1 hour.
  2. Explanatory Session: In the explanatory session, a video is shown that provides information about the clinical trial and the drug being tested. Following the video, there is a question and answer session where you can ask any questions you may have about the trial. This session is scheduled for approximately 30 minutes.
  3. Health Check: The health check involves a number of tests and checks. These include measuring your height and weight, conducting an ECG, checking your blood pressure, and performing an X-ray. A doctor will also perform a physical examination and have a brief interview with you. Finally, blood and urine samples will be collected for laboratory tests. This process typically takes around 1 hour.
  4. Orientation and Payment Session: In the orientation and payment session, you will be given detailed information about what to expect during the trial. Payment details will also be discussed. This process will take approximately 30 minutes.
