Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will test the effectiveness of topical thalidomide in healing mouth sores in HIV infected patients. Oral (PO) thalidomide heals these sores at a dose of 200 mg per day. However, PO thalidomide can cause drowsiness, skin rashes, allergic reactions, increased viral load, and even nerve damage that may not be reversible. This study will evaluate the efficacy of a topical formulation of thalidomide (placed directly on the surface of the sore) for the healing of these sores.

Persons with HIV infection of acquired immunodeficiency of at least 18 years of age with one or more chronic, painful intraoral lesions may be eligible for this study. Subjects must be referred by a primary care physician who is managing their care, and must have HIV/AIDS status confirmed. Patients' HIV treatment regimen will not be altered and those receiving highly active therapy will not be excluded.

Patients will be excluded if they are concurrently being treated for mucosal lesions (including topical or systemic steroids, viscous lidocaine, topical or systemic anti-fungals, or mouthwashes), or concurrent thalidomide therapy; receving chemotherapy or radiation therapy for neoplasms; using concurrent acute therapy for opportunistic infections; concurrent use of sedatives (such as CNS depressants or alcohol use); history of allergy to thalidomide; pre-existing peripheral neuropathy of grade II or higher; pregnant or lactating females or those not practicing contraception according to FDA guidelines for thalidomide.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The proposed clinical trial will evaluate the efficacy of topically-applied thalidomide as a treatment for painful oral lesions in HIV-infected patients. Limited data suggest that this drug may be effective when given systemically, but is accompanied by a high incidence of side effects. Administration of the drug topically onto the lesion should result in high local concentrations within the lesion thereby suppressing tumor necrosis factor which is thought to be related to the size and severity of the lesion. Subjects will be randomly allocated to one of three possible groups: systemic administration of thalidomide, topical administration of thalidomide, and placebo. The dose of thalidomide will be determined in a dose escalation pilot study prior to the main study. Healing, pain, and the incidence of side effects will be assessed at baseline and weekly for up to eight weeks. Successful demonstration of an enhanced therapeutic effect or reduced toxicity may provide a basis for the development of novel routes of administration and drugs for the treatment of painful oral lesions associated with HIV infection and other diseases.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Persons with HIV infection or acquired immunodeficiency of at least 18 years of age with one or more chronic, painful intraoral lesions will constitute the study sample for both studies.

Subjects must be referred by a primary care physician who is managing their care, and must have HIV/AIDS status confirmed and current CD4 status provided by the primary physician.

Patients' HIV treatment regimen will not be altered and those receiving highly active antiretroviral therapy will not be excluded.

Patients must be between ages 40 to 60 years.

Exclusion Criteria

Patients will be excluded from participation if taking any concurrent treatment for mucosal lesions (including topical or systemic steroids, viscous lidocaine, topical or systemic anti-fungals, or mouthwashes), prior to concurrent thalidomide therapy, chemotherapy or radiation therapy for neoplasms, concurrent acute therapy for opportunistic infection, concurrent use of sedatives (such as CNS depressants or alcohol use), history of allergy to thalidomide, pre-existing peripheral neuropathy of grade II or higher, and females of childbearing potential.

Pregnant or lactating females will be excluded.
