We are not physicians. Always confer with your dr. about A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA) conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA) Clinical research trials and A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA) medical trials happen in hundreds of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually measure the effectualness of new drugs. The intention of the studies / undertakings is to solve certain human healthcare questions. Clinical trials are a popular manner for mDs, government agencies, and private sector companies to locate treatments for all forms of circumstances, such as A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA). A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA) Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment choices before they are available to the general public. Some times the human subjects get treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA) clinical trial. Participants frequently get the best healthcare available for their A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA) condition. Risks are a reality, nonetheless, and can include extra or frequent physician trips, medical risks (possibly life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with exacting guidelines to protect clinical trials subjects.

A Phase I Safety and Immunogenicity Trial of HIV-1 gp120 C4-V3 Hybrid Polyvalent Peptide Immunogen Mixed in Mineral Oil Containing Mannose Mono-Oleate (IFA)
For Condition: HIV Infections
Status: Completed
Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) ,
Synopsis: To evaluate the safety of HIV-1 gp120 C4-V3 hybrid polyvalent peptide immunogen (C4-V3 peptides) formulated in mineral oil containing mannose mono-oleate (IFA) in HIV-1 uninfected volunteers. To evaluate the humoral and cellular immune responses to the C4-V3 peptides as measured by the induction of 1 or more of the following: neutralizing antibodies to HIV-1 MN and RF, cross-neutralizing antibodies to primary isolates of HIV-1, HIV-1 antigen-specific lymphoproliferation, CD8+ and CD4+ cytotoxic T lymphocyte (CTL) activity specific for HIV-1 gp120 or V3 peptides corresponding to the vaccine strains of HIV-1, induction of HLA-B7 and HLA-A2 restricted CD8+CTLs, and induction of HIV-specific DTH responses. The test immunogen (C4-V3 peptides) is constructed from 4 sequences of the HIV-1 V3 gp120 loop shared by approximately 80% of North American HIV-1 strains. Because of the critical role that this region plays in generating anti-HIV sequences, it is hypothesized that the test immunogen (C4-V3 peptides) will be capable of inducing a broad range of cross-reactive neutralizing antibodies in the majority of recipients.
Details: The test immunogen (C4-V3 peptides) is constructed from 4 sequences of the HIV-1 V3 gp120 loop shared by approximately 80% of North American HIV-1 strains. Because of the critical role that this region plays in generating anti-HIV sequences, it is hypothesized that the test immunogen (C4-V3 peptides) will be capable of inducing a broad range of cross-reactive neutralizing antibodies in the majority of recipients. Twenty-eight volunteers are randomized to receive two 0.5 ml injections of C4-43 peptides in IFA or placebo (IFA alone) administered intramuscularly at 0, 1, 6, and 12 months. At least 50% of all volunteers (6 per Groups I and II; 2, Group III) must be HLA-B7 phenotype.
Eligibility:
Study Type: Interventional, Prevention, Double-Blind, Safety Study
Minimum Age/Maximum Age: 18 Years/60 Years
Genders: Both
Protocol Entry Criteria: Inclusion Criteria Volunteers must have: - Negative ELISA for HIV within 8 weeks of immunization. - Normal history and physical examination. - Normal chest x-ray within 4 weeks prior to initial immunization. - Low-risk sexual behavior as defined by AVEG. Exclusion Criteria Co-existing Condition: Volunteers with the following conditions are excluded: - Medical or psychiatric condition that precludes compliance with the protocol, including recent suicidal ideation or present psychosis. - Occupational responsibilities which preclude compliance with the protocol. - Active syphilis (if the serology is documented to be a false positive or due to a remote [more than 6 months] treated infection, the volunteer is eligible). - Active tuberculosis (volunteers with a positive purified protein derivative and a normal chest x-ray showing no evidence of TB and not requiring isoniazid therapy are eligible). - Positivity for hepatitis B surface antigen. Volunteers with the following prior conditions are excluded: - History of immunodeficiency, chronic illness, malignancy, or autoimmune disease. NOTE: Individuals with a history of cancer are excluded unless there has been surgical excision followed by a sufficient observation period to give a reasonable assurance of cure. - History of suicide attempts or past psychosis. - History of anaphylaxis or other serious adverse reactions to vaccines. - History of serious allergic reaction to any substance, requiring hospitalization or emergent medical care (e.g., Stevens-Johnson syndrome, bronchospasm, or hypotension). - History of lung disease. Prior Medication: Excluded: - Live attenuated vaccines within 60 days of study. NOTE: Medically indicated subunit or killed vaccines (e.g., influenza, pneumococcal) are not exclusionary, but should be given at least 2 weeks away from HIV immunizations. - Experimental agents within 30 days prior to study. - HIV-1 vaccines or placebo, received in a previous HIV vaccine trial. - Immunosuppressive medications. Prior Treatment: Excluded: - Receipt of blood products or immunoglobulin in the past 6 months. Risk Behavior: Excluded: - Alcohol intake greater than or equal to the equivalent of 1 oz of 100 proof per day (4 oz. glass of wine or 12 oz. of beer per day). - Identifiable higher-risk behavior for HIV infection as determined by screening questions designed to identify risk factors for HIV infection; specific exclusions include a history of injection drug use within the last 12 months prior to enrollment and higher- or immediate-risk sexual behavior as defined by the AVEG (i.e., meeting the criteria for AVEG Risk Groups C and D).
