KIO-301

Encinitas, California--(News - June 25, 2024) - Kiora Pharmaceuticals (NASDAQ: KPRX) has appointed Roger A. Goldberg, MD, MBA, a vitreoretinal surgeon at Bay Area Retina Associates (BARA) to its Scientific Advisory Board. As an advisor, Dr. Goldberg will contribute scientific insights and valued clinical perspectives to aid Kiora's development of new therapeutics to address retinal diseases with high unmet needs. "As a surgical specialist in retinal disease, my clinical experiences highlight the need for novel and improved treatment options that reverse and/or modify the progression of vision threatening retinal diseases," said Dr. Goldberg. "Kiora's investigational drug, KIO-104, is one example of an asset with this potential given its ability to target overactive immune cells implicated in a wide range of retinal diseases including macular edema, uveitis, and inflammation related vision impairment. I look forward to contributing to Kiora's efforts to advance their technologies so that they may one day benefit as many patients as possible." Dr. Goldberg has been an investigator in dozens of interventional retinal therapeutic clinical trials. His research has been published extensively including first-author publications in The New England Journal of Medicine, Ophthalmology, JAMA Ophthalmology, and American Journal of Ophthalmology (AJO). He serves as a reviewer for the AJO and Retina, and regularly serves as faculty at national and international meetings. Additionally, Dr. Goldberg co-founded and is currently on the board of directors of Emmecell, a clinical-stage ophthalmic-focused biotechnology company developing regenerative, cell-based therapies for eye diseases. Eric Daniels, MD, MBA, Chief Development Officer of Kiora, emphasized the strategic importance of Dr. Goldberg's extensive research background and clinical expertise. "Dr. Goldberg's contributions will enhance our Company's goal to identify and translate innovative treatment options within the ophthalmic field. Retinal inflammation underpins vision loss in a wide range of sight threatening conditions. Starting with KIO-104, Dr. Goldberg's insight will aid in optimizing the development path of a potential first-in-class and clinically practical treatment option for the millions of patients diagnosed with retinal disease globally each year." Dr. Goldberg graduated from both college and medical school at Yale University. He completed his residency in Miami at the Bascom Palmer Eye Institute, one of the nation's premier eye hospital and residency-training programs. He completed a fellowship in Vitreoretinal Diseases and Surgery at Tufts University and Ophthalmic Consultants of Boston. Dr. Goldberg is board certified by the American Board of Ophthalmology and is an active member of the American Society of Retinal Specialists, the Retina Society, the Association for Research in Vision and Ophthalmology, and the American Academy of Ophthalmology. Dr Goldberg joins the existing members of Kiora's Scientific Advisory Board, including the following key thought leaders: Dr Robert Casson, MD, PhD – Consultant Ophthalmologist at the Royal Adelaide Hospital and Head of the Ophthalmic Research Lab, University of Adelaide. Dr Allen Ho, MD – Attending Vitreoretinal Surgeon and Director of Research at the Wills Eye Hospital, Professor of Ophthalmology at Thomas Jefferson University and partner of Mid Atlantic Retina. Dr Christine Kay, MD, PhD – Inherited Retinal Disease specialist and Vitreoretinal Surgeon at Vitreoretinal Associates in Gainesville, FL and Affiliate Assistant Professor at the University of South Florida. Dr Mark Pennesi, MD, PhD – Inherited Retinal Disease specialist and Director of Ophthalmic Genetics at Retina Foundation of the Southwest.

Pharmaceuticals）用于治疗遗传性耳聋的在研基因疗法DB-OTO使1名11个月大的患者的听力在接受治疗24周内恢复到了正常水平。图片来源：123RFFLT201：公布1/2期临床试验的新数据 Freeline Therapeutics公司公布了其在研基因疗法FLT201进行中的1/2期GALILEO-1试验的最新临床数据。FLT201是一种潜在“first-in-class”与“best-in-class”的在研腺相关病毒（AAV）基因疗法，用于治疗1型戈谢病成年患者。该疗法旨在提供一次性治疗，以持续增加患者体内GCase表达并减少有害底物的积累，阻止疾病进展，让患者不必终生接受治疗。FLT201采用Freeline的AAVS3衣壳，将新型基因引入肝细胞，生产经过理性设计的GCase变体。在临床前研究中，该GCase变体在溶酶体pH条件下的半衰期比野生型人类GCase增加了20倍以上。在临床前研究中，FLT201可导致GCase高度表达并减少关键组织中的底物。此次公布的结果显示，FLT201能显著降低此前曾长期使用获批疗法且葡萄糖基神经酰胺（lyso-Gb1）水平持续较高的1型戈谢病患者的lyso-Gb1水平，该指标是临床应答的最佳预测指标之一。此外，患者的骨髓负担和疲劳方面也出现了初步的改善迹象。安全性方面，FLT201具有良好的安全性和耐受性，未出现输注反应或严重不良事件。一些患者的谷丙转氨酶（ALT）水平轻微升高，但通过免疫疗法进行控制后，对疗效没有影响。ATSN-201：公布1/2期临床试验的新数据 Atsena Therapeutics公司公布了其在研基因疗法ATSN-201用于治疗X连锁视网膜劈裂症（XLRS）的1/2期临床试验的新数据。ATSN-201使用的新型扩散衣壳AAV.SPR能够横向扩散到视网膜下注射点以外的位置，实现对中央视网膜的安全和有效的基因递送（在XLRS患者的视网膜中，分裂腔主要集中在中央视网膜部位）。此前的研究显示，AAV.SPR在临床剂量下能够有效递送载荷至视网膜中央凹上的视锥细胞，无需手术分离，并且不会引起炎症。此次公布的数据显示，首个队列（低剂量组）的3名患者中有两名在给药8周后开始出现视网膜分裂的广泛改善。第24周（目前可获得的最新时间点）时，分裂仍在继续改善。在视网膜下注射点内外都发现了分裂腔的改善区域，这表明AAV.SPR正在从注射点横向扩散，与这种新横向扩散衣壳的预期特征一致。在视网膜结构改善的相同位置也观察到了功能改善。一名患者的视力改善高达14 dB，其中38个位置的视力改善超过7 dB。美国FDA认为，在≥5个预先指定的位置至少改善7 dB是具有临床意义的。该组所有3名XLRS患者对ATSN-201的耐受性良好，未报告严重不良事件。DB-OTO：公布1/2期临床试验的初步数据再生元公布了其用于治疗遗传性耳聋的在研基因疗法DB-OTO的1/2期临床试验的初步积极结果。DB-OTO是一种在研细胞选择性AAV基因疗法，旨在通过AAV载体将OTOF基因的健康拷贝传递至耳蜗毛细胞，为因OTOF基因突变导致的先天性深度听力损失患者提供持久的生理性听力。此前，DB-OTO已获得了FDA的孤儿药资格、罕见儿科疾病认定以及快速通道资格。一名患者在11个月大时就接受了DB-OTO治疗，在24周内听力恢复到正常水平，而另一名在4岁时接受该疗法的患者也在治疗后6周时初步观察到听力有所改善。这两名儿童都因OTOF基因变异而在出生时患有严重的遗传性耳聋，其中接受治疗的11个月大儿童是全球最早接受基因疗法治疗遗传性耳聋的患者之一。HORA-PDE6b：公布1/2期临床试验数据 Coave Therapeutics公司新成立的子公司eyeDNA Therapeutics宣布，其用于评估HORA-PDE6b的1/2期临床试验24个月时的随访结果良好。HORA-PDE6b是一种以AAV5为载体的基因疗法，用于治疗PDE6b基因双等位基因突变引起的视网膜色素变性。此次公布的结果显示，在接受高剂量治疗且症状较轻的患者亚组中，在24个月时报告了在最佳矫正视力（BCVA）和Goldmann视野（GVF）结果方面的积极疗效。未治眼睛的BCVA与基线相比增加了0.09 LogMar，而经治眼睛的视力保持稳定（+0.02 LogMar）。从基线开始，未治眼睛的GVF平均减少了超过300 deg²，而经治眼睛则相对稳定。低剂量组患者（n=7）在五年期间的长期数据发现，未治眼睛的BCVA持续下降（从第二年开始每年增加0.05到0.08 LogMAR），这与疾病的自然病程相符。与此同时，同一组中经治眼睛的BCVA与基线相比保持稳定，在同样的随访期内仅增加了0.03到0.06 LogMAR）。第5年时，经治眼睛与未治眼睛与基线相比的BCVA平均变化的差距为0.25 LogMAR（12个字母）。此外，用于评估视杆细胞功能的蓝光全视野刺激测试（FFST）持续显示出经治眼睛的光感知阈值有改善的趋势，具有临床意义。临床关注亚组在随访12个月时观察到的积极视网膜解剖学评估趋势保持到了随访24个月时。在24个月的研究期后，患者对高低两种剂量的HORA-PDE6b耐受性都很好。发生了5例眼部严重不良事件（SAE），包括2例可能与HORA-PDE6b相关的已解决的SAE（1例脉络膜视网膜炎和1例视力下降）。这些患者未接受预防性口服皮质类固醇。NGN-401：公布1/2期临床试验的初步数据 Neurogene公司公布了其用于治疗Rett综合征的基因疗法NGN-401的1/2期临床试验的初步安全性和耐受性数据。NGN-401是一种在研AAV基因疗法，递送表达全长人甲基胞嘧啶结合蛋白2（MeCP2）的转基因。NGN-401利用Neurogene专有的基因调控技术，提供高度控制和一致的MeCP2表达，从而避免了与常规基因治疗相关的过表达相关毒性。在临床相关剂量的NGN-401非临床研究中，Rett综合征的主要特征得到改善，未观察到过表达毒性。此次公布的结果显示，在接受治疗后约9个月、6个月和3个月的随访中，3名患者对NGN-401的耐受性普遍良好。所有与NGN-401相关的不良事件均为轻度或1级，并且是短暂或可消退的。大多数不良事件是AAV的已知潜在风险，未报道任何MeCP2过表达毒性的体征或症状。RG6501（OpRegen）：公布1/2a期临床试验的新数据 Lineage Cell Therapeutics公司公布了其同种异体视网膜色素上皮（RPE）细胞疗法RG6501（OpRegen）用于治疗年龄相关性黄斑变性（AMD）继发地理萎缩（GA）的1/2a期临床试验的24个月的数据。结果显示，接受OpRegen细胞后至少2年内，患者眼睛的视网膜外层结构和视觉功能获得了持续的改善，OpRegen细胞可以通过抵消宿主RPE细胞功能障碍和损失来为GA区域内剩余的视网膜细胞提供支持。与基线值相比，队列4中的10名患者的BCVA在接受治疗后24个月时平均增加了5.5个字母，其中5名OpRegen覆盖GA病变更广的患者的治疗效果更好，BCVA平均增加了7.4个字母。经光学相干断层扫描（OCT）检查发现，OpRegen覆盖GA病变更广的患者的视网膜外层结构持续得到改善。FT819、FT522：公布1期临床试验的初步数据Fate Therapeutics公司宣布，其现货型CD19靶向嵌合抗原受体（CAR）T细胞疗法FT819用于治疗系统性红斑狼疮的1期临床试验完成了首例患者的输注。此外，该公司还公布了FT819治疗复发/难治性B细胞恶性肿瘤（BCM）的1期研究数据，及现货型CD19靶向CAR自然杀伤细胞（NK）细胞疗法FT522治疗复发/难治性B细胞淋巴瘤（BCL）的1期研究的初步临床观察结果。结果显示，FT819和FT522均能诱导快速、深度和持续的CD19+ B细胞耗竭。ACE1831：公布1期临床试验的初步数据Acepodia公司公布了其现货型CD20靶向抗体偶联异体γδ2 T细胞疗法ACE1831用于治疗非霍奇金淋巴瘤的1期剂量递增试验的初步数据。ACE1831利用γδ T细胞上高表达的NK细胞激活受体来清除恶性血细胞，在体外和体内模型中都显示出了对癌细胞增强的细胞毒性。此次公布的结果显示，ACE1831单次给药（最低剂量）治疗后，5名患者中有1名出现完全缓解（CR），3名达到了疾病稳定（SD）。在这些患者中，1名CR和2名SD患者曾接受过CD19靶向CAR-T细胞疗法。在ACE1831单次给药后的三个月内，观察到了持续的临床缓解。最低剂量的ACE1831耐受性良好，没有出现与ACE1831相关的严重不良事件，包括移植物抗宿主病（GVHD）、神经毒性、高级别细胞因子释放综合征（CRS）或剂量限制性毒性反应。BI 764524：公布1/2a期临床试验数据勃林格殷格翰（Boehringer Ingelheim）公司公布了其靶向Sema3A的人源化单克隆抗BI 764524的积极1/2a期临床试验数据。新闻稿指出，该研究是首个探索糖尿病黄斑缺血（DMI）潜在疗法的研究。BI 764524旨在重建缺血区域的血管并减少视网膜的渗漏，为解决视网膜疾病中的视网膜非灌注问题提供了可能性。研究发现，BI 764524在玻璃体内单剂量和多剂量给药后耐受性良好，达到了主要安全性终点，并显示出潜在疗效的早期迹象。该研究在第16周达到了预先指定的早期疗效标准，即与假手术相比FAZ的面积稳定（p<0.2）。在短期试验期内，其他次要疗效终点未显示出相关变化。KIO-301：公布1/2期临床试验的新数据Kiora Pharmaceuticals公司公布了其用于治疗视网膜色素变性的小分子光控开关（Photoswitch）KIO-301的1/2期临床试验的新数据。KIO-301能够选择性地赋予视网膜神经节细胞（RGC）光敏能力，旨在绕过退化的光感受器将神经信号传递到大脑。此前患者报告的结果表明，在注射KIO-301后，其感知光的能力、描绘明暗对比的能力以及整体视觉功能都有所改善。并且在研究过程中没有报告不良事件，包括眼部不良事件。此次公布的结果显示，在所有评估的时间点，接受治疗患者的大脑视觉处理中心中的神经活动比基线有统计学上的显著增加，且基线时视力较好患者的神经活动增加更明显。与先前报道的视野、视力和功能性视力的改善一致，这种大脑活动的增加是时间依赖性的。▲患者大脑视觉处理中心中的神经活动较基线时显著增加（图片来源：参考资料[8]）CK-4021586（CK-586）：公布1期临床试验数据Cytokinetics公司公布了其用于治疗射血分数保留型心力衰竭（HFpEF）的心脏肌球蛋白抑制剂CK-4021586（CK-586）的1期临床试验的初步数据。CK-4021586是一种新型、选择性、口服小分子心肌酶抑制剂，旨在减轻HFpEF引起的心肌过度收缩。在临床前模型中，CK-586通过减少心脏收缩过程中活性肌球蛋白交叉桥的数量，从而降低收缩力，减轻了心脏的过度收缩。该1期研究达到了主要终点，表明CK-586在健康受试者中的安全性和耐受性良好，且具有线性的药代动力学特征。使用超声心动图评估的药效学结果与预期一致。研究中未观察到严重不良事件，且尚未达到停药标准。这些数据支持CK-586进入2期临床试验，预计将于2024年第四季度启动。▲欲了解更多前沿技术在生物医药产业中的应用，请长按扫描上方二维码，即可访问“药明直播间”，观看相关话题的直播讨论与精彩回放参考资料（可上下滑动查看）[1]
