项目摘要
Project Summary / Abstract
The Medicines for Malaria Venture (MMV) recently published a “roadmap” for the types of medicines that are
needed to support the long-term goal of malaria eradication. The roadmap consists of a wish list of target
candidate profiles (TCP) and medicines (target product profiles, i.e., TPP). With the most recent revision to the
anti-malarial target candidates and product profiles the MMV highlighted the need for identifying new medicines
for chemo-protection and chemo-prevention with long-acting molecules, and/or parenteral formulations (i.e.,
TCP-2) (Burrows, JN et al., 2017, Malaria Journal, 16:26). According to their updated roadmap new drugs are
needed to protect populations entering areas of high endemicity during the final stages of malaria elimination.
And drugs with causal liver-stage activity are needed for chemoprevention to prevent infection or outbreak of
resistance during malarial seasons. This TCP has been modeled on the combination drug atovaquone +
proguanil. The MMV envisions that an injectable sustained-release formulation could be developed as a long-
acting preventative providing up to 3 to 4 months of protection.
As a potent and selective inhibitor of the parasite’s cytochrome bc1 complex, ELQ-300 targets Plasmodium
falciparum in the blood and liver stages and even kills parasites developing in the midgut of the mosquito vector.
With support from the NIH and US DOD we have been successful in developing an oral formulation of prodrug
ELQ-331 for use in humans for weekly prophylaxis against malaria, work that was performed in collaboration
with SRI International. In the present application we seek NIH support for a comprehensive assessment of ELQ-
300 prodrugs for intramuscular injection to effect the sustained-release of drug from an oil depot (or other
extended release matrix) into the host bloodstream at levels above the minimum effective concentration needed
to block liver stage infection by infectious sporozoites. In collaboration with SRI International we will leverage
our knowledge of ELQ-300 prodrug chemistry, crystallinity, stability, and solvent/vehicle solubility with their
expertise in formulation design and optimization to identify the optimal ELQ-300 prodrug design that is paired
with an optimal depot formulation to provide long-term protection of animals from sporozoite infection. Four
different prodrug chemistries will be evaluated and compared, varying R-group chain length to optimize the
physiochemical properties of the drug and to enhance solubility in vehicles and mixtures that are approved for
human use. The overall goal is to develop a long-acting sustained release formulation of an ELQ-300 prodrug
for chemo-protection against malaria.
项目摘要/摘要
疟疾风险药物(MMV)最近出版了针对药物类型的“路线图”
需要支持消除疟疾的长期目标。路线图由目标清单组成
候选剖面(TCP)和药物(目标产品概况,即TPP)。与最近的修订
抗疟疾目标候选和产品概况MMV强调了识别新药物的需求
用于使用长效分子和/或父母公式的化学保护和化学预防(即
TCP-2)(Burrows,Jn等,2017,Malaria Journal,16:26)。根据更新的路线图,新药是
在消除疟疾的最后阶段,需要保护进入高流行地区的人群。
化学预防需要具有因果肝脏阶段活性的药物,以防止感染或爆发
疟疾季节的抵抗力。该TCP已在联合药物Atovaquone +上进行了建模
前卫。 MMV设想可以将注射持续释放公式作为长期开发
采取预防措施,最多可以保护3到4个月。
作为寄生虫细胞色素BC1复合物的潜在和选择性抑制剂,ELQ-300靶向疟原虫
在血液和肝脏阶段,恶性菌,甚至杀死在蚊子媒介中肠发展的寄生虫。
在NIH和US DOD的支持下,我们已经成功地开发了前药的口头公式
ELQ-331用于人类用于每周预防疟疾的疟疾,在合作中进行的工作
与SRI International。在本应用中,我们看到NIH支持ELQ-的全面评估
300例肌内注射的前药,以实现油库中持续释放的药物(或其他
扩展释放矩阵)以高于最低有效浓度的水平进入宿主血液
通过传染性孢子虫阻塞肝脏阶段感染。与SRI International合作,我们将利用
我们对ELQ-300前药,结晶度,稳定性和偿付能力/车辆可溶性的了解
公式设计和优化方面的专业知识,以识别配对的最佳ELQ-300前药设计
具有最佳的仓库公式,可长期保护动物免受孢子岩感染。四个
将评估和比较不同的前药化学,不同的R组链长度可以优化
该药物的生理化学特性,并提高批准的车辆和混合物的溶解度
人使用。总体目标是开发ELQ-300前药的长效持续释放公式
用于抗疟疾的化学保护。
