A Phase I Pharmacokinetic and Tolerance Study of 28-Day Regimens of Oral Ganciclovir
United States48 participants
Plain-language summary
To determine the pharmacokinetics (blood levels) of three dose treatment plans of oral ganciclovir during a 28-day dosing period. Other purposes of the study are to determine in a population of HIV seropositive persons with cytomegalovirus (CMV) viremia, the safety, tolerance, and patient acceptability of oral ganciclovir given for 28 days, to collect preliminary laboratory evidence for antiviral activity and effectiveness of three dose regimens of oral ganciclovir based on blood and urine cultures of CMV, and to relate antiviral activity to dosage and to serum ganciclovir levels.
CMV retinitis is an important sight-threatening opportunistic infection which affects about 10 to 15 percent of people with AIDS. A previous study has shown that treatment with ganciclovir resulted in a significant delay in time to first retinitis progression compared to untreated controls. More studies are warranted to evaluate effects at different doses.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
