To evaluate the safety and immunogenicity of ALVAC-HIV MN120TMG (vCP205) in comparison to ALVAC-RG rabies glycoprotein (vCP65) as a control when administered in HIV-1 negative volunteers. ALVAC-HIV vCP205 is a second generation candidate vaccine that can be used to induce a humoral and cellular response against several antigens. This recombinant construct is based on the canarypox vector termed ALVAC and expresses gp120 of the HIV MN strain, plus the transmembrane portion of the LAI strain as well as gag and protease.
To determine the safety of and immune response to vaccinia-derived HIV-1 recombinant envelope glycoprotein (gp160) at a dose of 200 mcg in human volunteers; to evaluate duration of antibody response and its relationship to the dose and frequency of inoculation. Although recent advances have been made in antiviral therapy against AIDS, there is currently no cure for AIDS. It is likely that the ultimate control of the disease depends on the development of safe and effective vaccines against HIV.
To determine the effects of zidovudine (AZT) alone and in combination with didanosine (ddI) on viral load in the lymphoid tissue and blood of antiretroviral-naive, HIV-infected patients with CD4 counts greater than or equal to 550 cells/mm3. Recent studies have shown that during the asymptomatic phase (clinical latency) of HIV infection, there is an extraordinarily large number of infected CD4+ lymphocytes and macrophages throughout the lymphoid system, both in latent and productive states. These findings support the belief that early intervention therapy with reverse transcriptase inhibitors could prolong the clinical latency period.
To compare the efficacy and safety of clarithromycin combined with rifabutin, ethambutol, or both in the treatment of disseminated Mycobacterium avium Complex (MAC) disease in persons with AIDS, including individuals who have or have not received prior MAC prophylaxis. It is believed that effective therapy for MAC disease in patients with AIDS requires combinations of two or more antimycobacterial agents in order to overcome drug resistance and the unfavorable influence of the profound immunosuppression associated with AIDS. Data suggest that clarithromycin may have substantial activity in two- or three-drug combination regimens with clofazimine, rifamycin derivatives, ethambutol, or the 4-quinolones.
To evaluate the safety and efficacy of liposomal doxorubicin hydrochloride ( DOX-SL ) alone or in combination with bleomycin and vincristine in the long-term treatment of AIDS-related Kaposi's sarcoma. To determine whether the 3-drug combination enhances progression-free survival and quality of life. Liposomal formulations of chemotherapeutic agents increase drug accumulation in tumors, which permits disease palliation at relatively low doses and thus decreases some of the dose-limiting toxicity. Multi-agent therapy is considered to be more effective than single-agent therapy; therefore, DOX-SL will be combined with bleomycin and vincristine.
To determine the safety of immunization with HIV-1 C4-V3 polyvalent peptide vaccine in HIV-infected persons. To determine the proportion of study participants immunized who develop new specificities or increased levels of neutralizing and other antibody responses, T-cell proliferative responses, and Class I restricted cytotoxic T-lymphocyte ( CTL ) responses. HIV-1 C4-V3 polyvalent peptide vaccine contains amino acid sequences for selected epitopes from four of the most common HIV isolates in the United States and Europe, predicted to represent about 50-90 percent of the HIV isolates in the United States. It includes epitopes that generate potentially salutary immune responses and deletes epitopes that generate immune responses which might contribute to further immunopathogenesis.
To evaluate the effect of MSL 109, human monoclonal anti-cytomegalovirus (CMV) antibody, on time to progression of CMV retinitis. To determine the safety and pharmacokinetic profile of MS 109. To evaluate the relationship between pharmacokinetic measurements of MSL 109 and efficacy and virologic markers. Therapeutic agents currently available for CMV retinitis are limited by their inherent toxicities and short half-lives which require frequent intravenous dosing. Alternatively, MSL 109 has demonstrated safety and effectiveness in neutralizing CMV isolates at concentrations easily maintained in AIDS patients.
To determine whether alternating oral ganciclovir with intravenous ( IV ) ganciclovir can prevent relapse of Cytomegalovirus ( CMV ) retinitis and improve quality of life in AIDS patients. A systemic treatment strategy for CMV retinitis is needed that will be effective yet convenient to administer, without the need for a permanent indwelling IV catheter. Although oral ganciclovir has been used as maintenance following induction with IV ganciclovir, patients with reactivation of disease must be reinduced IV. A fixed-schedule regimen in which oral and IV ganciclovir are alternated may prevent reactivation and progression of disease, as opposed to the current therapeutic strategy in which changes in therapy are event-driven. Also, the duration of intermittent IV therapy required to control disease may be short enough to eliminate the need for an indwelling catheter.
To compare the effect of stavudine (d4T) alone or with zidovudine (AZT) versus didanosine (ddI) alone or with AZT on CD4 counts, HIV RNA levels, and viral load in HIV-infected patients [AS PER AMENDMENT 3/21/97: To compare the effects of d4T alone versus ddI alone versus AZT plus ddI]. To compare the safety of d4T/AZT. AS PER AMENDMENT 3/21/97: To evaluate the pharmacokinetic interactions of AZT and d4T both at an extracellular and intracellular level. Although AZT and ddI can delay the advancement of HIV disease, the benefit of either of these drugs has proven to be only temporary. d4T, a new nucleoside analog with a favorable toxicity profile and demonstrated activity against HIV, offers an additional therapeutic option. It is reasonably assumed that the benefit of an antiretroviral agent in terms of delaying clinical disease progression is directly related to its ability to achieve and sustain viral suppression; thus, this study measures effects on viral load and CD4 count.
To assess response and toxicity in patients with fluconazole-resistant oral candidiasis ( thrush ) when given initial induction with amphotericin B oral suspension. Experience with amphotericin B oral suspension for drug-sensitive thrush in HIV-infected patients is limited but encouraging.
