PROJECT SUMMARY/ABSTRACT The overarching goal of this proposed program is to develop an innovative, end-user informed HIV pre- exposure prophylaxis (PrEP) product as an Acceptable Multi-user Biodegradable Extended Release (AMBER) implant. The implant technology addresses multiple challenges with current PrEP drug delivery systems (DDS) by offering beneficial attributes: user-independence and discretion of use, zero-order (sustained) release, long-term protection (≤1 year), retrievability and biodegradation of the polymeric implant. We propose to engineer the implant to be retrievable throughout the drug delivery period, in the case of adverse reactions or an end-user’s wish to discontinue. Otherwise, the AMBER implant will remain in-place and biodegrade after drug depletion. Uniquely, the AMBER implant decouples drug delivery features from biodegradation properties, which enables zero-order kinetics of drug release. The AMBER program addresses the goals of this National Institutes of Health (NIH) opportunity (RFA-AI-19-063) for the development of new and innovative sustained/extended release (SER) DDS for HIV PrEP with novel (non- tenofovir based) antivirals (ARV). We will inform implant development by eliciting preference insights from diverse gender, sexual orientation, and ethnic/racial minority populations in two priority geographical areas under “Ending the HIV Epidemic” initiative in the United States. We propose three specific aims: (1) develop the AMBER implant with polymers optimized for high durability and bioerosion profiles; (2) formulate selected ARVs and evaluate safety, pharmacokinetics, and efficacy of lead AMBER implants in preclinical studies; (3) identify Preferred User Characteristics (PUCs), inform technology development and future deployment of AMBER into practice by conducting iterative socio-behavioral research with Young MSM, cis- and trans- gender women in California and Alabama. We will strive to align PUC and key modifiable attributes during product development: sustained (≤1 year) delivery of novel ARV, polymers designed to optimize biodegradation timescales, incorporation of end-user acceptability information into a Target Product Profile (TPP), and evaluation of efficacy in nonhuman primate model. The AMBER program is milestone-driven and provides defined deliverables to product development efforts to support future needs in clinical translation.

项目概要/摘要 该拟议计划的总体目标是开发一种创新的、最终用户知情的艾滋病毒预防方案。 作为可接受的多用户可生物降解缓释剂的暴露预防 (PrEP) 产品 （琥珀色）植入物。植入技术解决了当前 PrEP 药物输送的多重挑战 系统（DDS），通过提供有益的属性：用户独立性和使用自由裁量权，零阶 聚合物的（持续）释放、长期保护（≤1年）、可回收性和生物降解性 注入。我们建议将植入物设计为在整个药物输送期间均可回收， 出现不良反应或最终用户希望停止使用的情况。否则，AMBER 植入物将保留 药物耗尽后就地并生物降解。独特的是，AMBER 植入物解耦了药物输送功能 来自生物降解特性，这使得药物释放能够实现零级动力学。琥珀计划 解决了美国国立卫生研究院 (NIH) 机会 (RFA-AI-19-063) 的目标 开发新的和创新的持续/延长释放（SER）DDS，用于 HIV PrEP，具有新颖的（非 基于替诺福韦的）抗病毒药物（ARV）。我们将通过收集偏好见解来为种植体开发提供信息 两个优先地理区域的不同性别、性取向和少数族裔/种族人口 在美国“结束艾滋病毒流行”倡议下。我们提出三个具体目标：（1）发展 AMBER 植入物采用针对高耐用性和生物侵蚀特性进行优化的聚合物； (2)制定选定 抗逆转录病毒药物并在临床前研究中评估先导 AMBER 植入物的安全性、药代动力学和功效； (3) 确定首选用户特征 (PUC)，为技术开发和未来部署提供信息 通过与年轻的 MSM、顺式和反式进行迭代社会行为研究，将 AMBER 付诸实践 加利福尼亚州和阿拉巴马州的性别女性。我们将努力在期间调整 PUC 和关键可修改属性 产品开发：持续（≤1年）交付新型抗逆转录病毒药物、旨在优化的聚合物 生物降解时间尺度，将最终用户可接受性信息纳入目标产品概况 （TPP），以及在非人类灵长类动物模型中的功效评估。 AMBER 计划是由里程碑驱动的， 为产品开发工作提供明确的可交付成果，以支持临床翻译的未来需求。
