Study Details

Study Description

Brief Summary

To determine the safety and tolerance of methotrexate in HIV-infected patients. To determine the dose effective in modulating key markers of immune activation. To determine a dose suitable for Phase II or III evaluation in HIV-infected patients.

In HIV infection, complete immunological clearance of the foreign antigen does not occur, resulting in chronic immune activation. Because chronic immune activation may contribute to disease progression in HIV infection, immunomodulators may have therapeutic value in early HIV disease prior to development of opportunistic infections. The clinical benefits of methotrexate appear to derive from an anti-inflammatory effect; thus, it may reduce the state of chronic immune activation.

Condition or Disease	Intervention/Treatment	Phase
HIV Infections	Drug: Lamivudine Drug: Methotrexate Drug: Zidovudine	Phase 1

Detailed Description

Patients are randomized to receive methotrexate at Dose 1 or 2 (low doses) for 12 weeks, with 8 weeks of follow-up. If interim safety monitoring and viral burden results for the two cohorts support continuation, a third cohort of patients receive methotrexate starting at Dose 2 for the first 2 weeks, then at Dose 3 for the next 2 weeks, and at Dose 4 for the remaining 8 weeks, with 8 weeks of follow-up.

AS PER AMENDMENT 1/10/97:

The Dose 1 (the lowest dose) has been eliminated; the first 10 patients are now assigned to the next higher dose. Depending upon the results of interim safety data, the next cohort will be entered on the escalating dose regimen.

Also per this amendment, all patients will receive zidovudine and lamivudine for 30 days prior to the initiation of methotrexate, during the 12 weeks of methotrexate administration, and for the 8 weeks of follow-up.

Concurrent Medication:

Excluded:

Immunosuppressive or immunomodulatory drugs.
Chronic nonsteroidal anti-inflammatory agents.
Newly initiated antiretrovirals.
Bone marrow suppressive drugs (e.g., TMP/SMX).

Concurrent Treatment:

AS PER AMENDMENT 1/10/97: Excluded:

History of intolerance to zidovudine or lamivudine.

Prior Medication:

Excluded:

Prior chemotherapy for malignancy.

Prior Treatment:

Excluded:

Prior radiotherapy for malignancy. Alcohol abuse.
