Reductions in HIV acquisition have slowed, and the global community is significantly off track from global goals. Oral pre-exposure prophylaxis (PrEP) alone cannot address the diverse needs of the millions of people at risk of HIV acquisition. Long-acting injectable cabotegravir (CAB-LA) received United States Food and Drug Administration approval for HIV prevention in December 2021. When studied, CAB-LA demonstrated high effectiveness, provides months of protection versus daily use, is preferred by some users and has the potential to achieve commodity cost reduction. These factors position CAB-LA to catalyse transformation in HIV prevention. Significant work must be undertaken to ensure at-scale uptake in low- and middle-income countries. Leveraging decades of product introduction experience, Clinton Health Access Initiative (CHAI) has developed an innovative roadmap to support equitable CAB-LA introduction, comprising tightly executed market-shaping, product development, regulatory, and programmatic and implementation action.
Proven models exist (e.g. long-acting reversible contraceptives, paediatric tuberculosis treatment and antiretrovirals (ARVs), such as paediatric dolutegravir and tenofovir disoproxil fumarate, lamivudine, and dolutegravir) for partnership-driven, accelerated, impactful product introduction. Based on learnings from these models and needs in the prevention space, CHAI developed a roadmap to maximize the near-term impact of CAB-LA and accelerate the development of, access to and impact of quality-assured, low-cost generic CAB-LA. This roadmap is intended to inform introduction planning and investment decision-making across a range of stakeholders, including donors, governments, manufacturers and other partners working in the HIV prevention space. Elements include (1) ensuring coordination and alignment across partners, and avoiding redundancy experienced during oral PrEP introduction; (2) preparing national programmes and providing support to maximize impact, including the development of national policies, guidelines and introduction plans; system strengthening; quantification and procurement; and addressing evidence needs, among other areas; (3) supporting community engagement, ensuring that demand generation and delivery approaches are person-centred and community-led; (4) incentivizing generic product development through, for example, milestone-based commercialization incentives and product development cost-sharing; and (5) expediting regulatory reviews.
Accelerating access to affordable, generic CAB-LA can transform progress towards HIV epidemic control. This vision of impact at scale in prevention is achievable, if informed by results-backed approaches to introduction.
艾滋病毒感染的减少速度已经放缓,全球社会在实现全球目标方面明显落后。单独使用口服暴露前预防(PrEP)无法满足成百上千万有感染艾滋病毒风险的人的多样化需求。2021 年 12 月,美国食品和药物管理局批准了长效注射用卡替拉韦(CAB-LA)用于艾滋病毒预防。研究表明,CAB-LA 具有高度有效性,与每日使用相比,提供数月的保护,一些使用者更喜欢它,并且有可能降低商品成本。这些因素使 CAB-LA 能够推动艾滋病毒预防的变革。必须开展大量工作,以确保在中低收入国家大规模采用。借鉴几十年来的产品引入经验,克林顿健康倡议组织(CHAI)制定了一项创新路线图,以支持公平引入 CAB-LA,其中包括紧密执行的市场塑造、产品开发、监管以及方案和实施行动。
已经有经过验证的模式(例如长效可逆避孕方法、儿科结核病治疗和抗逆转录病毒药物,如儿科多替拉韦和替诺福韦二吡呋酯、拉米夫定和多替拉韦)用于伙伴关系驱动、加速、有影响力的产品引入。根据这些模式的经验教训以及预防领域的需求,CHAI 制定了路线图,以最大限度地发挥 CAB-LA 的近期影响,并加速高质量、低成本通用 CAB-LA 的开发、获取和影响。该路线图旨在为一系列利益相关者(包括捐助者、政府、制造商和其他在艾滋病毒预防领域工作的合作伙伴)的引入规划和投资决策提供信息。要素包括:(1)确保合作伙伴之间的协调和一致,避免在引入口服 PrEP 时出现的重复;(2)准备国家方案并提供支持以最大限度地发挥影响,包括制定国家政策、准则和引入计划;加强系统;量化和采购;以及解决证据需求等领域;(3)支持社区参与,确保需求产生和交付方法以个人为中心并由社区主导;(4)通过基于里程碑的商业化激励措施和产品开发成本分担等方式激励通用产品开发;(5)加快监管审查。
加快获得负担得起的、通用的 CAB-LA 可以改变艾滋病毒流行控制方面的进展。如果通过引入基于结果的方法实现这一大规模预防影响的愿景,那么这是可以实现的。
