Completed Phase I DIONE-01 study demonstrates clinical activity and long-term safety of roginolisib, a unique allosteric modulator of PI3Kδ Patients with uveal melanoma showed a doubling of overall survival compared to historical controls Site activation ongoing for randomized Phase II OCULE-01 study in uveal melanoma GENEVA and AMSTERDAM, Dec. 11, 2024 /PRNewswire/ -- iOnctura, a clinical-stage biopharmaceutical company combating neglected and hard-to-treat cancers, today provides a clinical update on its lead asset, roginolisib. Results from the completed Phase I DIONE-01 study are due to be presented at the European Society for Medical Oncology Immuno-Oncology (ESMO-IO) annual congress tomorrow, 12 December at 12:30 CET (presentation 164P). Allosteric modulator of PI3Kδ, roginolisib, has a unique chemical structure and binding mechanism which makes it highly specific for PI3Kδ, giving it an advantageous pharmacology profile and an unprecedented safety profile compared to previous generations of PI3Kδ inhibitors. Roginolisib is being investigated in solid and hematological malignancies including uveal melanoma (UM), a rare cancer of the eye. Eye melanoma is a rapidly growing market which is projected to be worth USD 9.56B by 2032[1]. The two-part Phase I study DIONE-01, firstly evaluated continuous daily dosing of roginolisib [at 10, 20, 40 and 80 mg] in 24 patients with pretreated solid tumors and follicular lymphoma (FL), and secondly evaluated a dose confirmation cohort in 20 UM patients. Results from DIONE-01 show: Study met its primary objective to determine the safety of the anticipated optimal biologically effective dose (BED): Roginolisib was well tolerated at the recommended Phase II dose (RP2D) of 80mg, with <7% Grade 3/4 treatment-emergent adverse events (TEAEs) considered to be related to roginolisib. TEAEs did not result in immune-related toxicity, or dose-limiting toxicity, in either solid tumor or hematological patients. In contrast to prior PI3Kδ inhibitors, roginolisib dosing did not require dose modifications. Roginolisib is well tolerated over long periods of treatment, up to 4.5 years. Median overall survival (OS) was 16 months for the 29 patients with UM treated with roginolisib, who had previously received a median of two prior therapies. This exceeds the median OS of 7 months observed in historical controls in patients receiving immunotherapies as second line treatment[2]. Median progression free survival (PFS) was 5 months for patients treated with roginolisib versus less than 3 months for historical controls2. Clinical findings validate the mechanism of action of roginolisib: roginolisib reduces immune-suppressive immune cells and chemokines, UM-related tumor clones (ctDNA) and PI3K-related signaling indicating a rebalancing of the immune system. Catherine Pickering, Chief Executive Officer of iOnctura, said: "The Phase I DIONE-01 data highlight the benefits of roginolisib for patients with uveal melanoma and advanced cancers. Roginolisib's unique allosteric binding mechanism has translated into a differentiated beneficial clinical profile, including a doubling of overall survival compared to historical controls in uveal melanoma. We are delighted to announce these data support progression of roginolisib into a randomized Phase II study." Professor Michele Maio, University of Siena and Principal Investigator of the roginolisib studies, added: "Being able to continue to investigate roginolisib in a randomized Phase II study is a positive step to understand more about this already well tolerated molecule. Roginolisib has given prolonged disease stabilization to patients with uveal melanoma who have exhausted all other therapeutic options. So far, these patients have maintained a good quality of life without major limitations. I'm looking forward to seeing what the Phase II trial delivers over the coming months." Activation of trial sites for the Phase II OCULE-01 study (NCT06717126) investigating roginolisib versus investigator's choice in the second-line+ treatment of uveal melanoma is ongoing. About iOnctura iOnctura is a clinical-stage biopharmaceutical company combating neglected and hard-to-treat cancers with precision oral small molecules that target cancers in novel ways. The bold new treatments extend lives and improve healthspans, changing the outlook for patients and their families. Two therapeutic candidates have progressed into mid-stage clinical development: roginolisib is the first allosteric modulator of PI3Kδ; and cambritaxestat is the only autotaxin inhibitor in clinical development to treat cancer. iOnctura BV is headquartered in Amsterdam, The Netherlands with its wholly owned Swiss subsidiary, iOnctura SA, located in Geneva, Switzerland. iOnctura is backed by specialist institutional investors including Syncona, EIC Fund, M Ventures, Inkef Capital, VI Partners and Schroders Capital. About roginolisib Roginolisib is an allosteric modulator of PI3Kδ with a unique chemical structure and binding mode. The PI3K signaling pathway is one of the most commonly dysregulated pathways in cancer and the precise targeting of the PI3Kδ isoform delivers substantial anti-tumor effects with a low-toxicity profile. Clinical data have demonstrated roginolisib's excellent safety profile and sustained clinical activity in uveal melanoma (UM), a rare eye cancer with few available treatments. Site activation for the randomized Phase II OCULE-01 study in uveal melanoma is ongoing, and Phase II studies in other cancers, including non-small cell lung cancer and myelofibrosis, are in planning.

关注并星标CPHI制药在线 2024年11月21日，英矽智能宣布，公司自主研发的小分子创新药ISM5939已经获得美国食品药品监督管理局（FDA）的IND批件，用于治疗实体瘤。ISM5939是一款口服ENPP1抑制剂，有望实现每日一次（QD）给药，具有"同类最佳"的治疗潜力。 ISM5939的快速问世，得益于英矽智能的Pharma.AI平台。平台中生成式AI引擎Chemistry42在分子设计中效率极高，从项目启动到先导化合物仅用3个月时间，远超传统开发模式。 2023年5月，英矽智能提名ISM5939为临床前候选化合物，临床前实验结果显示ISM5939展现出强大的抗肿瘤效果，具有良好安全性特征、体外ADMET特性和体内药代动力学（PK）特征，有望为肿瘤免疫和低磷酸酯酶症（HPP）提供新的治疗选择。 AI驱动的药物发现流程 以英矽智能首款AI药物ISM001-055为例。ISM001-055靶向致命罕见病特发性肺纤维化（IPF），该疾病以成纤维细胞增殖和大量细胞外基质沉积导致的肺功能受损为特征，确诊后的中位生存期仅为2-3年。目前，仅有不足30%的患者能从已经获批的针对性疗法中获益，且IPF的发病率还在以惊人的速度不断增长，标志着大量未被满足的临床需求。 为搭建最初的疾病靶点假说，研发团队采用隶属英矽智能Pharma.AI平台的靶点发现引擎PandaOmics，首先在按照年龄和性别注释的组学数据和临床数据集上进行训练，再利用2016年发表在Nature Communications的iPANDA算法，通过深度特征合成、因果关系推断和全新通路重建提名潜力靶点。此后，团队融合自然语言处理（NLP）引擎，基于涵盖专利、出版物、研发基金、临床试验等文本数据的百万级文件进行新颖性评估和疾病-靶点关联度评分。 在PandaOmics平台揭示的20个潜力靶点中，Traf2 和 Nck 相互作用激酶（TNIK）脱颖而出，最终被确定为重点研究对象。历史研究已经说明TNIK和WNT、TGF-β、Hippo、JNK、NF-k等纤维化驱动通路相关，然而并未提出TNIK作为IPF潜在治疗靶点的可能性。此后，团队利用健康肺组织和IPF患者纤维化肺组织的单细胞基因表达数据集验证了 TNIK 与 IPF 的相关性，并证实了 TNIK 在纤维化组织中的富集。 靶点确定后，团队利用同属于Pharma.AI的生成化学平台Chemistry42，采用基于结构的药物设计（SBDD）策略，生成了一种安全、特异性、高效的TNIK抑制剂。平台同时采用30个生成式AI模型进行化合物设计，构成虚拟结构库，并接收专业研发团队的反馈进一步优化虚拟筛选过程。多次筛选后，TNIK ATP结合位点被选为目标结合口袋，其中一个具有潜力的先导化合物表现出了优良的活性，IC50值达到纳摩尔级别。 基于上述化合物从头生成步骤，研发团队开展进一步优化，在提高溶解度、优化ADME特性、减低毒性的同时，保留候选分子对TNIK靶点的强大亲和力，最终于2021年初提名ISM001-055为临床前候选化合物（PCC）。此时距离TNIK被PandaOmics提名为潜在IPF治疗靶点，仅仅过去了18个月。值得一提的是，ISM001-055在多种纤维化动物模型中获得了验证，标志着AI驱动的药物发现由理论成为现实。在诱导肺纤维化的小鼠和大鼠中，ISM001-055通过降低成纤维细胞活化、减少纤维化蛋白沉积、减轻肺部炎症改善肺功能。此外，ISM001-055还在两个体内模型中减轻了皮肤和肾脏纤维化，表现出泛纤维化抑制效用，表明了潜在的适应症扩展机会。 ENPP1靶点研究进展 胞外核苷酸焦磷酸酶／磷酸二酯酶家族（ENPP）是一类具有相同保守结构的胞外蛋白。迄今为止，已有７个家族成员被鉴定（ENPP1-7）；其中，ENPP1、ENPP3、ENPP4和ENPP5水解核苷酸，而ENPP2、ENPP6和ENPP7通过催化结构域进化为磷酯酶。 ENPP1在许多组织中表达，是胞外环磷酸鸟苷-腺苷合成酶最主要的水解酶，因此，在心血管、神经、免疫、肌肉骨骼、激素和血液功能等调节中起重要作用。ENPP1高表达与肿瘤转移、免疫逃逸、多癌种较差预后相关。 研究结果显示，ENPP1抑制剂可通过调节胞外cGAMP水平激活cGAS-STING通路，进而增强宿主免疫系统抗肿瘤效果。有研究表明，ENPP1可能是乳腺癌中肿瘤免疫逃逸的驱动因素。故患者ENPP1的表达水平，可以作为临床研究中的依据，甚至作为区分患者的生物标志物。 STING是肿瘤免疫的潜在靶点，激活STING可促进肿瘤免疫。但目前披露的STING激动剂的临床疗效不佳，促使人们寻找其他激活STING的治疗方案，ENPP1就是其中一个。在肿瘤中，STING被2′3'-cGAMP激活，通过分泌干扰素介导天然免疫和非天然免疫过程。ENPP1是目前发现的唯一能够水解2′3'-cGAMP的酶，抑制ENPP1可以促进STING的激活。 由于2′3′-cGAMP是胞质DNA经酶催化生成，DNA正常情况下在细胞核和线粒体中，仅在病原体入侵、肿瘤等病理情况才会进入胞质中。正常细胞不含2′3'-cGAMP，STING信号通路没有活性，也不能通过对ENPP1的抑制激活STING信号通路，所以ENPP1抑制剂能够选择性地激活肿瘤细胞和肿瘤微环境中其他细胞的STING信号通路，实现高选择性。 ENPP1抑制剂可以通过防止细胞外的cGAMP被降解来激活细胞内的STING信号通路，同时减少免疫抑制分子腺苷的生成。所以ENPP1抑制剂在肿瘤免疫治疗中可以起到"一箭双雕"、"一石二鸟"的作用。 临床试验中的靶向ENPP1药物 ENPP1仍然是一个较为新颖的药物靶点。据不完全统计，目前在全球研的ENPP1抑制剂约20余种，仅有5款进入临床阶段，其中4款针对的领域为肿瘤，1款针对的是罕见病领域。ENPP1抑制剂与放疗联用在动物模型上取得较好的效果，还可以与免疫检查点抑制剂及PARP抑制剂联用。 其中进展最快的是Inozyme Pharma开发的INZ-701，已进入3期临床。INZ-701是一种重组Fc融合蛋白，正在开发中作为ENPP1酶替代疗法，用于治疗血管、软组织和骨骼的罕见疾病。在临床前研究中，这种实验性疗法已显示出预防病理性矿化和内膜增生的潜力，这些问题可导致如ENPP1缺乏症、ABCC6缺乏症和钙化防御等毁灭性遗传疾病的发病率和死亡率。目前，INZ-701已被FDA和欧洲药品管理局（EMA）授予了孤儿药名称，用于治疗ENPP1缺乏症。今年7月，INZ-701还被FDA授予用于治疗ABCC6缺乏症的快速通道资格认定。 INZ-701正在进行3期临床开发，用于治疗ENPP1缺乏症、ABCC6缺乏症和钙化防御。2024年4月，Inozyme Pharma宣布了其在成人ABCC6缺乏症患者中进行的INZ-701持续第1/2期试验的积极顶线安全性和免疫原性数据。在血管病理学、视觉功能和患者报告结果（PROs）方面观察到了临床改善。 RBS 2418是由Riboscience LLC公司研发的口服ENPP1抑制剂，目前处于临床1期。2023 ESMO大会上发布了一项1期剂量递增试验探索了RBS2418单独或联合帕博利珠单抗在难治性实体瘤中的应用。研究结果显示，100 mg、200 mg和400 mg的RBS2418单用或与帕博利珠单抗联用均安全可控且耐受性良好。PK曲线显示，在给药周期内RBS2418可完全抑制ENPP1的血浆水平。目前该研究仍在进行中，其初步分析显示肿瘤中的ENPP1和cGAS共表达水平与RBS2418治疗引起的免疫激活和长期疾病稳定相关。 此外，国内征祥医药的一款小分子ENPP1抑制剂ZX-8177片近日也获得CDE临床试验默示许可，拟开发治疗晚期实体瘤。ZX-8177是一款小分子ENPP1抑制剂，该产品的临床前研究结果曾连续两年入选美国癌症研究协会（AACR）年会。根据2022年和2023年AACR年会公布的临床前研究结果，ZX-8177可通过cGAMP-STING通路有效促进IFN-β1的产生。在CT-26同基因小鼠模型中，ZX-8177按2mg/kg BID治疗14天，可达到37%~60%左右的肿瘤生长抑制（TGI），并显著增加肿瘤微环境中NK细胞、T细胞和M1/M2巨噬细胞比例。该产品还具有有良好的DMPK和安全药理学特征，支持其作为进一步开发的临床候选药物。据悉，ZX-8177获批临床后，将在首次人体临床研究中探索其作为单一药物和联合疗法的初步疗效和安全性。 参考来源 1、CDE官网 2、1.
