About this study
To assess the toxicity profile and determine the maximum tolerated dose (MTD), if possible, of S-1153 administered orally 3 times daily for 14 days. To investigate the clinical pharmacokinetic parameters for S-1153. To assess anti-HIV activity associated with S-1153 administration through evaluation of CD4 and viral load measurements.
Read the detailed description
Two separate schedules of S-1153 are administered on this study: single dose (2 dose levels/cohorts) and repeated dose administration over 14 days (escalation through 4 dose levels/cohorts). All doses are determined by body weight.
Single-dose study (Cohort 1):
(4 patients) low-dose po, following a standardized morning meal. (4 patients) low-dose po, fasting.
Single-dose study (Cohort 2), administered during the first 3 levels of the repeated dose study and prior to the initiation of the 4th repeated dose level:
(4 patients): intermediate-dose po, following a standardized morning meal. (4 patients): intermediate-dose po, fasted. Following treatment with S-1153, all single-dose patients (Cohorts 1and 2) are observed for 21 days.
Repeated dose (escalation) study:
All doses are administered for 14 days. Three patients are entered at the starting dose of S-1153. In the absence of dose-limiting toxicity (DLT), subsequent 3-patient cohorts are entered at 3 escalating doses.
The last patient at any given dose level must be observed for 21 days prior to entry of patient at the next dose. If 1 of the initial 3 patients experiences DLT at a given level, 3 additional patients will be added at that dose; if no additional toxicity occurs, escalation resumes. If 2 or more patients at a given dose exhibit DLT, the previous dose is declared the maximum tolerated dose (MTD) and 3 additional patients (6 total) are treated at that dose.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
To assess the toxicity profile and determine the maximum tolerated dose (MTD), if possible, of S-1153 administered orally 3 times daily for 14 days. To investigate the clinical pharmacokinetic parameters for S-1153. To assess anti-HIV activity associated with S-1153 administration through evaluation of CD4 and viral load measurements.
Detailed description
Two separate schedules of S-1153 are administered on this study: single dose (2 dose levels/cohorts) and repeated dose administration over 14 days (escalation through 4 dose levels/cohorts). All doses are determined by body weight.
Single-dose study (Cohort 1):
(4 patients) low-dose po, following a standardized morning meal. (4 patients) low-dose po, fasting.
Single-dose study (Cohort 2), administered during the first 3 levels of the repeated dose study and prior to the initiation of the 4th repeated dose level:
(4 patients): intermediate-dose po, following a standardized morning meal. (4 patients): intermediate-dose po, fasted. Following treatment with S-1153, all single-dose patients (Cohorts 1and 2) are observed for 21 days.
Repeated dose (escalation) study:
All doses are administered for 14 days. Three patients are entered at the starting dose of S-1153. In the absence of dose-limiting toxicity (DLT), subsequent 3-patient cohorts are entered at 3 escalating doses.
The last patient at any given dose level must be observed for 21 days prior to entry of patient at the next dose.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Capravirine in people with HIV Infections, run by Lexigen Pharmaceuticals at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 14 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2005.
