Development of a Practical Heroin-HIV Vaccine

描述（由申请人提供）：认识到HIV-1感染与注射海洛因的使用频繁相关，美国军方HIV研究计划（MHRP）和国家药物滥用研究所于2010年发起了一项合作机构间协议，以检查创建实用的抗海洛因疫苗（AHV）和HIV疫苗产品组合的可行性。基于最近对成功的MHRP RV 144泰国试验的多机构免疫相关性分析，该试验表明针对HIV-1 gp 120 V2环的抗体与针对HIV-1感染的保护相关，以及先前的研究表明对海洛因滥用的免疫保护的可行性，MHRP认为，存在一个独特的机会来创建一个候选肽疫苗艾滋病毒-1和海洛因。由于这种合作，现在已经创建了一种安全，廉价，基于海洛因-半抗原-肽，易于制造，强佐剂组合的候选AHV/HIV疫苗产品，该产品已准备好进行预期的I期和II期临床试验的优化和先进的临床前测试。如果成功，预计这种疫苗将提供一种可部署的海洛因疫苗，并将代表创造一种实用和有效的艾滋病毒疫苗的重大进展。主要目标是：（2）用最终的先导制剂在啮齿动物中进行先进的临床前免疫原性研究，以检查抗体同种型、亲和力、对海洛因和HIV gp 41和gp 120-V2环表位的特异性;（3）检测疫苗诱导的抗海洛因抗体，以预防啮齿动物和非人灵长类动物中与药物过量相关的麻醉作用和生理作用;（4）进行疫苗的中和和其他体外功能分析。

DESCRIPTION (provided by applicant): In recognition of the frequent association of HIV-1 infection with the use of injected heroin, the US Military HIV Research Program (MHRP) and the National Institute for Drug Abuse initiated a collaborative interagency agreement in 2010 to examine the feasibility of creating a practical combination anti-heroin vaccine (AHV) and HIV vaccine product. Based on the recent multi- institutional immune correlate analyses of the successful MHRP RV144 Thai trial that demonstrated that antibodies directed to the HIV-1 gp120 V2 loop correlated with protection against HIV-1 infection, together with previous studies that demonstrated the feasibility of immunoprotection to heroin abuse, MHRP believes that a unique opportunity exists to create a candidate peptide vaccine both to HIV-1 and heroin. As a result of this collaboration, a safe, inexpensive, heroin-hapten-peptide-based, easily manufactured, strongly adjuvanted combination candidate AHV/HIV vaccine product has now been created that is ready for optimization and advanced preclinical testing for anticipated phase I and phase II clinical trials. If successful it is anticipated that this vaccine will provid a deployable heroin vaccine and will represent a major advance for creation of a practical and effective HIV vaccine. The major goals are to: (1) optimize the hapten-gp41/gp120-T helper peptide-adjuvant-carrier formulation by examining the relative immune responses in rodents with three alternative identified lead heroin haptens; (2) perform advanced preclinical immunogenicity studies in rodents with the final lead formulation to examine antibody isotypes, affinities, specificities for heroin and HIV gp41 and gp120-V2 loop epitopes; (3) examine vaccine-induced anti-heroin antibodies for prevention of anesthetic effects and prevention of physiological effects associated with drug overdose in rodents and non-human primates; (4) perform neutralization and other in vitro functional analyses of vaccine- i
