Safety and Immunogenicity of MVA.HIVconsv in HIV-1 Seropositive Adults on HAART

2016年6月7日 更新者：University of Oxford

HIV-CORE 001 - A Randomised Placebo-controlled Study to Evaluate the Safety and Immunogenicity of a Candidate HIV-1 Vaccine, MVA.HIVconsv, Delivered by Intramuscular Needle Injection to HIV-1 Seropositive Adult Subjects Receiving Antiretroviral Therapy (ART).

In this study, the novel vaccine candidate, MVA.HIVconsv, will be tested for safety, tolerability and immunogenicity in HIV-1-seropositive subjects receiving effective antiretroviral therapy.

MVA.HIVconsv will be tested as a single vaccine modality, as a prelude to testing in a heterologous viral vector boost regimen which will include a replication-defective simian adenovirus expressing the same immunogen.

  • Willing and able to give written informed consent for participation in the study
  • Treated continuously with a combination of 3 or more antiretroviral agents for the preceding 12 months
  • Willing and able to adhere to an effective ART regimen for the duration of the study (switching from current regimen is allowed if for reasons of tolerability or toxicity)
  • CD4 cell count > 350 cells/μl at screening and at the preceding clinic visit
  • Plasma viral load < 50 copies / ml at screening and at the preceding clinic visit
  • No new AIDS-defining diagnosis or progression of HIV-related disease in the preceding 6/12 months

  • Haematological and biochemical laboratory parameters as follows:

    • Haemoglobin > 10g/dl
    • Platelets > 100,000/μl
    • ALT ≤ 2.5 x ULN
    • Creatinine ≤ 1.3 x ULN
  • Serology: negative for hepatitis B surface antigen OR HbsAg positive with HBV DNA < 1000 copies/ml; negative for hepatitis C antibodies OR confirmed clearance of HCV infection (spontaneous or following treatment); negative syphilis serology or documented adequate treatment of syphilis if positive EIA IgG or TPHA
  • Available for follow up for duration of study (screening + 38 weeks) and willing to comply with the protocol requirements
  • Women of child-bearing age must not be pregnant, planning a pregnancy or breast-feeding. Sexually active women must be willing to use an approved method of contraception from screening until 4 months after the third immunisation. Sexually active men in heterosexual relationships must be willing to use an approved method of contraception with their partners from screening until 4 months after the third immunisation.

Exclusion Criteria:

  • Confirmed HIV-2 seropositive
  • Positive pregnancy test
  • Participation in another clinical trial within 12 weeks of study entry
  • History of autoimmune disease other than HIV-related auto-immune disease which has resolved with ART
  • History or clinical manifestations of any physical or psychiatric disorder which could impair the subject's ability to complete the study
  • History of anaphylaxis or severe adverse reaction to vaccines
  • History of alcohol or drug dependency which could, in the opinion of the investigators, impair the subject's ability to complete the study
  • Previous immunisation with a recombinant MVA vaccine
  • Immunisation with any experimental immunogens within 6 months of study entry
  • Receipt of blood products or immunoglobulins within 6 months of study entry
  • Treatment for cancer or lymphoproliferative disease within 1 year of study entry
  • Receipt of vaccines other than Hepatitis B vaccine within 2 weeks of study entry or planned receipt within 2 weeks of vaccination
  • Any other prior therapy which, in the opinion of the investigators, would make the individual unsuitable for the study or influence the results of the study
  • Current or recent use (within last 3 months) of interferon or systemic corticosteroids or other immunosuppressive agents
