项目摘要

PROJECT SUMMARY Adolescents assigned female at birth (AFAB) in the United States (US) have unmet needs for pregnancy and HIV prevention; 75% of pregnancies in adolescents are unplanned and 12% of new HIV diagnoses occur in youth aged 13-24 years AFAB. Sexual and gender minority (SGM) youth may have particular vulnerabilities and yet their sexual and reproductive health needs are often overlooked or misunderstood. Multi-purpose prevention technology (MPT) products that can simultaneously prevent pregnancy, suppress menses, and prevent HIV are desirable, may bring efficiencies to both users and healthcare systems, and may serve to improve uptake of HIV prevention products among youth. Early studies suggest that adolescents AFAB would prefer an MPT that is discreet and long-lasting, with injections being a preferred delivery modality. The success of cabotegravir (CAB) as the first generally safe and highly effective long-acting systemic agent for HIV prevention opens up opportunities for the development of an injectable MPT that combines CAB with an effective contraceptive, like levonorgestrel (LNG); LNG has been widely used and has an established safety track record. CONRAD has developed a first-in-class long acting systemic MPT that consists of a bioresorbable injectable depot and that employs a novel drug delivery technology to deliver both CAB and LNG together for at least three months, and possibly longer. Pre-clinical studies in rats and non-human primates show promise. To advance the development of this injectable CAB/LNG MPT our team with complementary expertise will conduct studies to 1) assess the values and preferences for a novel MPT for pregnancy and HIV prevention in adolescent cisgender women (CW) and transgender men (TM) AFAB aged 16-24 years in the USA, using a combination of qualitative interviews and participatory attitudinal ranking approaches to inform the selection of attributes and levels for a Discrete Choice Experiment to be conducted in a sample of 200 CW and 200 TM AFAB; and 2) conduct a multi-site, phase I, single arm PK trial of the CAB/LNG injectable biodegradable depot in a sample of 16 healthy, HIV-negative adolescents and young adults AFAB, ages 18-24, to assess the safety and pharmacokinetic profile of the products in CW and TM AFAB who are receiving gender-affirming hormone therapy. Incorporation of end-user preferences for MPTs early on in product development can enhance acceptability, optimize uptake and use, and ultimately ensure public health benefit. The evaluation of the safety, acceptability and pharmacology of a first in-human CAB/LNG biodegradable depot injection in CW and TM youth will ensure that data on adolescents across genders is available for regulators should co-formulated CAB/LNG move forward for licensure. The availability of a highly effective, long-acting MPT that places a premium on safety and acceptability in adolescents AFAB across genders, has the potential to accelerate access to effective sexual and reproductive health, to potentially address disparities in health access for SGM populations, and to have a substantial impact on the HIV epidemic.
项目总结 美国出生女婴(AFAB)的怀孕需求未得到满足 和艾滋病毒预防;75%的青少年怀孕是计划外的,12%的艾滋病毒新诊断发生 13-24岁青年AFAB。性和性别少数群体(SGM)青年可能有特别的脆弱性 然而,他们的性健康和生殖健康需求往往被忽视或误解。多用途 预防技术(MPT)产品,可以同时防止怀孕,抑制月经,以及 预防艾滋病毒是可取的,可为用户和医疗保健系统带来效率,并可用于 提高青年对艾滋病毒预防产品的接受程度。早期研究表明,青少年AFAB会 更喜欢谨慎和持久的MPT,注射是首选的给药方式。成功之路 卡替格列韦(CAB)作为第一种普遍安全和高效的艾滋病毒长效全身用药 预防为开发可注射的MPT打开了机会,这种MPT将CAB和 有效的避孕药,如左旋诺孕酮(LNG);LNG已被广泛使用,并具有既定的安全性 有过往记录。康拉德已经开发出一流的长效系统性MPT,它包括一个 生物可吸收注射库,并采用一种新的药物输送技术来输送CAB和LNG 在一起至少三个月,甚至更长时间。大鼠和非人灵长类动物的临床前研究 拿出承诺。为了推动这种可注射的CAB/LNG MPT的开发,我们的团队与 专家将进行研究,以1)评估用于妊娠和艾滋病毒的新型MPT的价值和偏好 16-24岁青少年顺性女性(CW)和变性人男性(TM)AFAB的预防 美国,采用定性访谈和参与式态度排名相结合的方法 在200个CW样本中进行离散选择实验的属性和水平选择 和200 TM AFAB;以及2)进行CAB/LNG注射剂的多点I期单臂PK试验 可生物降解仓库在16名健康的、艾滋病毒阴性的青少年和年轻人的样本中,年龄在18-24岁之间, 评估CW和TM AFAB中正在接受治疗的产品的安全性和药代动力学 性别肯定荷尔蒙疗法。在产品早期纳入最终用户对MPTS的偏好 发展可以提高可接受性,优化吸收和使用,并最终确保公众健康利益。 首例人内CAB/LNG生物降解物的安全性、可接受性和药理学评价 在CW和TM青年中进行Depot注射将确保提供关于不同性别青少年的数据 监管机构应该联合制定CAB/LNG,以获得许可。提供一种高效、 长效MPT重视青少年AFAB的安全性和可接受性,不分性别,已经 有可能加速获得有效的性健康和生殖健康,潜在地解决差距问题 在特殊用途转基因人口获得卫生保健方面,并对艾滋病毒流行产生重大影响。
