Phase II Multi-Center Trial of ESK981 in Combination With Nivolumab in Patients With Metastatic Castrate Resistant Prostate Cancer

This phase II trial studies the side effects of ESK981 and nivolumab and to see how well they work for the treatment of castration resistant prostate cancer that has spread to other places in the body (metastatic). ESK981 is an investigational drug that targets several important pathways that are believed to play a role in the spread of cancer. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This study is being done to see if giving ESK981 and nivolumab together works better in treating metastatic castration resistant prostate cancer compared to usual treatments.

Increasing the response rates of immune checkpoint inhibitors in patients with metastatic castration-resistant prostate cancer (mCRPC) presents a significant challenge. ESK981 is a multi-tyrosine kinase and PIKfyve lipid kinase inhibitor that augments immunotherapeutic responses. In this phase II study, ESK981 was combined with the PD-1 blocking monoclonal antibody nivolumab to test for potentially improved response rates in patients with mCRPC who have progressed on androgen receptor (AR)-targeted agents and chemotherapy. Eligible patients received ESK981 orally once daily for five consecutive days, followed by a two-day break. Patients were also treated with nivolumab intravenously on Day 1 of each 28-day cycle. The primary endpoints were a 50% reduction in prostate-specific antigen (PSA50), and safety. Secondary endpoints included radiographic progression free survival (rPFS) and overall survival (OS). Additional investigations included whole exome sequencing in patients. Ten patients were enrolled. The maximum PSA decline from baseline of 14% was achieved in only one patient. Grade 3 treatment-related adverse events (AEs) included fatigue, anemia, and lymphopenia. There were no Grade 4 events. The median rPFS was 3.7 months (95% CI, 1.6-8.4). The median OS was 9.6 months (95% CI, 1.8-22.4). The study was terminated due to futility after 10 patients. Whole exome sequencing identified AR amplification in 63% of patients (5/8). ESK981 + nivolumab showed no antitumor activity in patients with AR-positive (AR+) mCRPC. Further evaluation of ESK981 combined with the PD-1 inhibitor nivolumab in AR + mCRPC patients is not warranted. (Trial registration: ClinicalTrials.gov NCT04159896. Registration date: November 12, 2019.).

ESK981 is a potent tyrosine kinase and PIKfyve lipid kinase inhibitor. This phase II trial evaluated the efficacy of ESK981 as a single agent in patients with androgen receptor-positive (AR +) metastatic castration-resistant prostate cancer (mCRPC). Eligible patients had mCRPC with progression on AR-targeted agents and without prior chemotherapy treatment. Each patient received 160 mg ESK981 once daily for 5 days per week for 4 weeks per cycle (except for an adverse event (AE) occurrence). The primary endpoints were a 50% reduction in prostate-specific antigen (PSA50), and safety. Secondary endpoints included the time and the duration of PSA response, PSA progression rates, PSA progression free survival (PFS) and overall survival (OS). Exploratory investigations included whole exome sequencing in patients before treatment, and morphological evaluation of biopsy samples pre- and post-treatment. PSA was evaluated in 13 patients. Only one patient (7.7% two-sided 95% Wilson CI (0.4%, 33.3%)) experienced a reduction in their PSA levels by 50% or more. The most common grade 3 treatment-related AEs were cardiac disorders, diarrhea, hypertension, alanine transaminase and aspartate transaminase elevations. No grade 4-5 events occurred. Median PFS was 1.8 months, and median OS was 12.1 months. Peripheral immune cells showed increased T cell activation and cytokine production in two patients who received 12-weeks of ESK981. Although relatively well tolerated, ESK981 alone showed no anti-tumor activity in patients with AR + mCRPC and its further evaluation as a single agent in AR + mCRPC is not warranted.

Recent outbreak of COVID-19 pandemic caused by severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) has raised serious global concern for public health. The viral main 3-chymotrypsin-like cysteine protease (M^pro), known to control coronavirus replication and essential for viral life cycle, has been established as an essential drug discovery target for SARS-CoV-2. Herein, we employed computationally screening of Druglib database containing FDA approved drugs against active pocket of SARS-CoV-2 M^pro using MTiopen screen web server, yields a total of 1051 FDA approved drugs with docking energy >-7 kcal/mol. The top 10 screened potential compounds against SARS-CoV-2 M^pro were then studied by re-docking, binding affinity, intermolecular interaction, and complex stability via 100 ns all atoms molecular dynamics (MD) simulation followed by post-simulation analysis, including end point binding free energy, essential dynamics, and residual correlation analysis against native crystal structure ligand N3 inhibitor. Based on comparative molecular simulation and interaction profiling of the screened drugs with SARS-CoV-2 M^pro revealed R428 (-10.5 kcal/mol), Teniposide (-9.8 kcal/mol), VS-5584 (-9.4 kcal/mol), and Setileuton (-8.5 kcal/mol) with stronger stability and affinity than other drugs and N3 inhibitor; and hence, these drugs are advocated for further validation using in vitro enzyme inhibition and in vivo studies against SARS-CoV-2 infection.Communicated by Ramaswamy H.

Nature Review | 抑制磷酸肌醇激酶，有望治愈所有疾病！

脂质磷酸肌醇是细胞各种生命活动的主要调节剂，由磷酸肌醇激酶严格调控产生。目前主要集中在I类磷酸肌醇3-激酶 (PI3K) 的药物治疗上，但近年来已经揭示了靶向几乎所有人类疾病中磷酸肌醇激酶的可能性，包括癌症、免疫缺陷、病毒感染和神经退行性疾病，开发更多磷酸肌醇激酶的强效和选择性抑制剂成为自然趋势。磷酸肌醇激酶可大致分为三个家族：第一个家族包含所有类别的磷酸肌醇3-激酶（PI3K）和III型PI4K，第二个家族包含PIP激酶，最后一个家族包含II型PI4K（图 1）。本文将对这三个家族的前沿进展进行详细分析。图1 磷酸肌醇和产生它们的磷酸肌醇激酶I类PI3K抑制剂磷酸肌醇激酶是多种人类疾病的治疗靶点，包括癌症、病毒感染、神经退行性疾病、发育障碍、糖尿病和炎症性疾病。目前，有许多I类PI3K抑制剂在临床上被批准用于治疗多种癌症。I类磷酸肌醇3激酶(PI3K)产生磷脂酰肌醇3,4,5-三磷酸(PIP3)，是细胞生长、代谢和免疫功能的主要调节剂。PI3K通路是癌症中突变最频繁的通路，PI3K的体细胞突变是多种人类癌症、原发性免疫缺陷、发育障碍和过度生长综合征的致病因素。PI3K 抑制剂的研发将为其他磷酸肌醇激酶抑制剂的设计提供信息。表1 I类PI3K抑制剂进展情况I 类PI3K以外的磷酸肌醇激酶抑制剂2.1 PIP激酶演化家族2.1.1 PIKfyve● 结构PIKfyve是真核生物中唯一催化从磷脂酰肌醇3-磷酸(PI3P)生产磷脂酰肌醇3,5-二磷酸(PI(3,5)P2)的蛋白质。除了脂质激酶活性外，PIKfyve还具有蛋白激酶活性，并受抑制性自磷酸化调节。PIKfyve复合体在离子稳态，内吞途径的内体运输、细胞迁移和溶酶体功能中发挥作用。对小鼠突变体和敲除模型以及患者临床突变的研究揭示了PIKfyve复合体所有成员在中枢和周围神经系统中的关键作用。图 2：PIKfyve 的结构-功能、抑制和治疗靶向● 药理抑制剂PIKfyve抑制剂通过破坏内溶酶体运输来阻断病毒进入宿主细胞质，从而显示出作为抑制病毒感染靶点的前景。能够改善神经退行性疾病，抑制病毒感染和癌症。目前已开发出多种PIKfyve抑制剂。大部分PIKfyve抑制剂还处于临床前阶段，如YM201636，MF4，APY0201，WX8，NDF和MOMIPP。第一个被发现的强效和选择性PIKfyve抑制剂YM201636源于针对I类PI3K的药物发现，它对PIKfyve非常有效，选择性是I类PI3Kp110α的100倍。PIKfyve抑制剂Apilimod和ESK981正在进行针对癌症和病毒感染的临床试验。PIKfyve抑制剂YM201636和Apilimod都阻断了帕金森病体外模型HEK293细胞中α-突触核蛋白的单体聚集。表2 PIKfyve抑制剂总结2.1.2 PI4P5Ks和PI5P4Ks● 结构PI(4,5)P2是哺乳动物细胞中最丰富的双磷酸化磷酸肌醇，而且还是基本癌症和代谢激酶PI3K的底物。负责产生PI(4,5)P2的激酶被分为两个亚家族，即I型和II型激酶。在哺乳动物中，I型PI4P5K家族由三种亚型（PI4P5Kα、PI4P5Kβ和PI4P5Kγ）组成，也存在三种哺乳动物II型PI5P4K亚型（PI5P4Kα、PI5P4Kβ和PI5P4Kγ）。图 3：PI4P5K 和 PI5P4K 的结构-功能和抑制● PI4P5Ks的药理学抑制剂迄今为止，已经报道了有限数量的有效和特异性PI4P5K抑制剂，并且仍处于临床前开发的早期阶段，它们被报道抑制癌症和炎症性疾病（表3）。其中最好的是ISA-2011B，它以高亲和力结合PI4P5Kα并在多种模型中抑制其蛋白质表达和癌症生长以及抑制炎症，但它具有显着的脱靶效应，进一步优化ISA-2011B，或开发另一种对PI4P5Kα具有更高选择性的基团，将是推进PI4P5Kα抑制剂超越临床前研究的必要条件。●PI5P4Ks的药理学抑制剂PI5P4K已成为p53无效肿瘤中有吸引力的药物靶标，并被认为是代谢的关键调节剂。临床前研究正在探索早期阶段的小分子抑制剂，包括泛PI5P4K抑制剂和亚型特异性PI5P4K抑制剂（表3），它们表现出抑制糖尿病，免疫性疾病，神经退行性疾病和抗癌效果，但目前尚未进入临床阶段。表3 PI4P5Ks和PI5P4Ks抑制剂总结2.2 PI3K−III型PI4K进化家族2.2.1 PI4KA和PI4KB● 结构有四种哺乳动物磷脂酰肌醇4-激酶(PI4K)，由II型（PI4KIIα和PI4KIIβ）和III型（PI4KIIIα和PI4KIIIβ，）组成，它们一起从磷脂酰肌醇中产生PI4P。PI4P在多种细胞器中介导了蛋白质的膜募集、整合膜蛋白活性的调节和细胞器之间的脂质转运。PI4KA和PI4KB蛋白具有与PI3Ks进化相关的同源螺旋和脂质激酶结构域（图4a、b）。然而，这两种蛋白质通过一组独特的蛋白质结合分子和翻译后修饰具有不同的调节模式。图 4：PI4KA 和 PI4KB 的结构-功能、抑制和治疗靶向● PI4KA的药理学抑制剂PI4KA在HCV感染中的关键作用促进有效和特异性PI4KA抑制剂的开发。PI4KB抑制剂可预防病毒感染，寄生虫感染，PI4KA和PI4KB抑制剂具有抗癌作用。表 4 III型PI4K和II、III类PI3K的抑制剂总结2.3 II类PI3K● 结构II类PI3K，也称为PI3KC2，存在α、β和γ三种亚型。PI3KC2s催化PI和PI4P的3-OH磷酸化；因此，它们似乎既是用于PI3P合成的III类PI3K的替代品，也是I类PI3K和5-OH磷酸酶介导的PI(3,4)P2生产的替代品。研究最深入的II类亚型是PI3KC2α，它在发育中起着至关重要的作用，PI3KC2α生成的PI(3,4)P2作为内吞作用的关键驱动因素。PI3KC2β中激酶死亡突变的纯合小鼠表现出葡萄糖耐量增强。图 5：II类PI3K的结构-功能、抑制和治疗靶向● 药理抑制剂PI3KC2的初始抑制剂是从I类PI3K抑制剂PIK-90的衍生物开发的，得到4-氨基烟酰胺衍生物MIPS-19416，它显示出对PI3KC2α和PI3KC2β的效力。高通量筛选和迭代药物化学优化的结合促成了高选择性PI3KC2α抑制剂(PITCOIN)的开发。PI3KC2α抑制剂能够抗血栓形成，抑制肺癌和黑色素瘤模型的血管生成和肿瘤生长。表5 II 类 PI3K抑制剂总结 2.4 III类PI3K：VPS34● 结构III类PI3K，VPS34是真核生物中的原始PI3K酶。它在体外和体内专门催化PI产生PI3P（图1），并且被发现为两种不同的四聚体复合物，即复合物I和复合物II。这两种复合物具有本质上相同的激活机制：通过每个复合物独有的一系列相互作用，将VPS34域从受抑制的构象中释放出来。这两个复合物在功能上是不同的，复合物I启动巨自噬，而复合物II调控内吞途径的流量。图 6：III 类 PI3K 的结构-功能、抑制和治疗靶向● III类PI3K的药理学二十多年前发现的自噬抑制剂3-甲基腺嘌呤(3-MA)可抑制VPS34，但选择性极差。最近，已经开发出几种有效且高度选择性的VPS34抑制剂用于临床前研究。最近的临床前研究也表明这些化合物可有效治疗癌症。表6 III类PI3K抑制剂总结展望许多磷酸肌醇激酶与各种血液学、神经学和传染病以及各种癌症有关。它们已被证明适合小分子抑制剂的开发，预示着作为真正治疗靶点的巨大潜力。已经为大多数PI3K超家族以及PIKfyve开发了高效和选择性抑制剂；这些都处于高级临床前研究阶段，甚至进入临床试验阶段，针对PI4P5Ks和PI5P4Ks以及II型PI4Ks也开发了有前景的工具化合物。参考资料：1.
