ClinConnect Summary
This clinical trial is testing a new medication called THB335 in healthy adults to see how it affects the body. The study is divided into two parts: the first part looks at how a single dose of the drug works, and the second part examines the effects of taking multiple doses over time. It’s important to note that this trial is "double blind," meaning neither the participants nor the researchers know who is receiving the actual medication and who is getting a placebo (a dummy treatment). This helps ensure the results are unbiased.
To be eligible for this trial, participants should be healthy adults aged between 18 and 65, with a body weight of at least 50 kg for men and 45 kg for women. They must not have any significant health issues or be using any tobacco products. Participants will have to understand and agree to the study's procedures by signing a consent form. If you decide to join, you can expect some medical tests to ensure you meet the health criteria, and then you will receive either the study drug or a placebo while being monitored for safety and any side effects. This trial is currently recruiting participants, so if you're interested, it's a good time to learn more!
