Who may be able to join

  • Patients must have:

  • Prior Medication:
  • Excluded:
  • Adefovir dipivoxil (bis-POM PMEA) for more than 14 days.
  • Within 2 weeks prior to entry:
  • Antiretroviral therapy, including nucleoside analogues, nonnucleoside reverse transcriptase inhibitors, protease inhibitors, or investigational antiretroviral agents.
  • Interferon (alpha, beta, or gamma) or interleukin (e.g., IL-2) therapy, aminoglycoside antibiotics, amphotericin B, cidofovir, diuretics, foscarnet, ganciclovir, itraconazole, fluconazole, ketoconazole (topical allowed), isoniazid, rifampin, rifabutin, clarithromycin, azithromycin, systemic chemotherapeutic agents, systemic corticosteroids, other agents with significant nephrotoxic potential, other agents that may inhibit or compete for elimination via active renal tubular secretion (e.g., probenecid), and other investigational agents.
  • Risk Behavior:
  • Excluded:
  • Active drug or alcohol abuse as demonstrated by a positive screening test for drugs of abuse (except marijuana or drugs used for medical indications) or substance abuse considered sufficient to hinder patient compliance.
  • Patients who are receiving:
  • Antiretroviral therapy, including nucleoside analogues, nonnucleoside reverse transcriptase inhibitors, protease inhibitors, or investigational antiretroviral agents. NOTE:
  • Antiretroviral therapy may be started after completion of the Day 49 follow-up visit (i.e., not earlier than 14 days after completion of dosing).
  • Interferon (alpha, beta, or gamma) or interleukin (e.g., IL-2) therapy, aminoglycoside antibiotics, amphotericin B, cidofovir, diuretics, foscarnet, ganciclovir, itraconazole, fluconazole, ketoconazole (topical allowed), isoniazid, rifampin, rifabutin, clarithromycin, azithromycin, systemic chemotherapeutic agents, systemic corticosteroids, other agents with significant nephrotoxic potential, other agents with significant nephrotoxic potential, other agents that may inhibit or compete for elimination via active renal tubular secretion (e.g., probenecid), and other investigational agents.

About this study

Official title: A Phase I/II, Randomized, Double-Blind, Placebo-Controlled Study of the Safety, Tolerance, Pharmacokinetics, and Antiviral Activity of 9-[2-(R)-[[Bis[[(Isopropoxycarbonyl)- Oxy]Methoxy]Phosphinoyl]Methoxy]Propyl]Adenine Fumarate (PMPA Prodrug) in HIV-Infected Patients

To evaluate the safety of single and multiple doses (28 daily doses) of 9-[2-(R)-[[bis[[(isopropoxycarbonyl)- oxy]methoxy]phosphinoyl]methoxy]propyl]adenine fumarate (PMPA) prodrug administered orally to HIV-infected patients. To determine the pharmacokinetics of single and multiple doses of PMPA prodrug when administered orally to HIV-infected patients. To evaluate the anti-HIV activity of PMPA prodrug, as demonstrated by increases in CD4 cell counts and decreases in HIV RNA, when administered orally as a single dose and daily for 4 weeks to HIV-infected patients with CD4 cell counts of 200 or more cells/mm3.

Read the detailed description

In this double-blind, placebo-controlled study, a total of 60 patients are randomized to receive PMPA prodrug at 1 of 5 doses or matching placebo tablets.

Part A (Days 1-7): Patients receive a single dose of PMPA prodrug or matching placebo tablets administered orally followed by a 1-week observation period. Patients who complete Part A without a dose-limiting toxicity begin Part B.

Part B (Days 8-35): Patients receive either PMPA prodrug or matching placebo tablets administered orally qd for 4 weeks at the same dosage level administered in Part A.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Tenofovir disoproxil fumarate in people with HIV Infections, run by Gilead Sciences at 3 sites 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 5 inclusion and 19 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: status not confirmed, 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 3 sites 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?

Results are not available in the source record.

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.
