What to expect

enhanced studyIf this study may be a fit for you, you will be invited to attend a screening visit at our facility in New Haven, CT. If you qualify for the study, there may be a period of up to 28 days before dosing begins.

If you participate, you will have 4 separate stays at the PCRU approximately 2 weeks apart, each for 4 consecutive nights, for a total of 16 overnights. You will receive a single oral dose of the study drug or a placebo the day after each admission to the PCRU.

Throughout the study, staff will monitor your health status, ask how you are feeling, and collect other data, such as the levels of the study drug in your blood. You will have one follow-up visit at the PCRU about a week after the last dose of the study drug, and one follow-up call about 4 weeks after the last dose.

Required overnight stays
16 overnights over 4 admissions
A participant may be required to stay overnight at the PCRU for observation and study procedures. The number and length of overnight stays is determined by the design of the study.
Long-term follow up
1 follow-up visit and 1 follow-up call
Some studies require the study team to stay in contact with the participant for a period of time after the participant completes the main part of the study. This long-term follow up is to collect additional information on the study drug over time.
How long is this study?
About 2.5 months (76 days)
This does not include the time between screening and dosing, which can be up to 28 days. Participants will be in this study for up to 76 days between the first dose and final follow-up call.
Up to 6,150 upon completion of the study
Participants in clinical trials at the PCRU receive financial compensation for their participation. The amount depends on factors like length of the stay, total number of study visits, and the nature of the study procedures.
Safety remains our top priority at the PCRU during COVID-19
