What to expect

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

There are 2 parts to this study. You will participate in either A or B. In Part A, you will be randomly assigned to receive either the study drug or placebo (contains no active medicine) as an oral liquid. In Part B, you will receive the active study drug as one or more tablets. In either part, you will receive a single dose.

You will stay overnight for 8 consecutive days at our facility. A follow-up call will occur 28 days after your dose. Throughout your participation, the study team will monitor your health status, ask how you are feeling, and collect other data about the study drug.

Required overnight stays
8 overnight stays
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 phone 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 36 days
This does not include the time between screening and first dose, which can be up to 28 days. Participants will be in this study up to 36 days from first dose to final follow-up call.
Up to $2,700 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.
