Clinical Details

Official title: A Phase 3, Randomized, Double-Blind, Multicenter Study of the Treatment of Antiretroviral-naive, HIV-1-Infected Patients Comparing Tenofovir Disoproxil Fumarate Administered in Combination With Lamivudine and Efavirenz vs. Stavudine, Lamivudine and Efavirenz.(Extension)

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

To compare the two treatment groups with the goal of achieving HIV-1 RNA levels less than 50 copies/mL at week 48.

To compare the safety, efficacy and tolerability of the two treatment regimens through 144 weeks of drug exposure.

Secondary outcome:

To evaluate the long-term efficacy, safety and tolerability of tenofovir DF in combination with lamivudine and efavirenz through approximately 336 weeks of drug exposure.

To evaluate the long term efficacy, safety and tolerability of tenofovir DF in combination with lamivudine and efavirenz through approximately 480 weeks of drug exposure.

Exclusion Criteria:

- Patients requiring therapy with any of the following: Nephrotoxic agents

(aminoglycoside antibiotics, IV amphotericin B, cidofovir, cisplatin, foscarnet, IV pentamidine, oral and IV vancomycin, oral and IV ganciclovir, other agents with significant nephrotoxic potential);Probenecid; Systemic chemotherapeutic agents; Systemic corticosteroids; Interleukin-2 (IL-2); Investigational agents (except on approval by Gilead Sciences); Drugs that interact with efavirenz (astemizole, terfenadine, dihydroergotamine, ergotamine, midazolam, triazolam, cisapride, rifampin, ergonovine, methylergonovine, voriconazole). Administration of any of the listed medications is not allowed throughout the duration of the study period.

- Pregnant or lactating patients.

- Evidence of a gastrointestinal malabsorption syndrome or chronic nausea or vomiting

which may confer an inability to receive an orally administered medication.

- Current alcohol or substance abuse judged by the investigator to potentially

interfere with patient compliance.

- Malignancy other than cutaneous Kaposi's sarcoma (KS) or basal cell carcinoma.

Patients with biopsy-confirmed cutaneous KS are eligible, if they are not anticipated to require systemic therapy during the study.

- Active, serious infections(other than HIV-1 infection) requiring parenteral

antibiotic therapy.

- Any other clinical condition or prior therapy that, in the opinion of the

investigator, would make the patient unsuitable for the study or unable to comply with the dosing requirements.
