(Nasdaq: RGLS), a biopharmaceutical company focused on the discovery and development of innovative medicines targeting microRNAs (the 'Company' or 'Regulus'), today announced the dosing of the first patient in the third cohort of the Phase 1b MAD study of RGSL8429 for the treatment of ADPKD..

圣地亚哥，2023年11月2日/PRNewswire/-Regulus Therapeutics Inc.（纳斯达克股票代码：RGLS），一家专注于发现和开发针对microRNA的创新药物（“公司”或“Regulus”）的生物制药公司，今天宣布RGSL8429第1b期MAD研究第三阶段第三队列中第一名患者用于治疗ADPKD的剂量。。

'After announcing the completed safety review of available data and the advancement to cohort three last month, we are excited to now be dosing our first patient in the third cohort,' said Jay Hagan, CEO of Regulus Therapeutics. 'Our Phase 1b MAD clinical trial remains on track, and we look forward to sharing topline data from the second cohort of the study in the first quarter of 2024.'.

Regulus Therapeutics首席执行官杰伊·哈根（Jay Hagan）说：“在宣布对现有数据进行完整的安全性审查并于上个月提升至三个队列后，我们很高兴现在可以为第三个队列中的第一位患者服药。”我们的1b期MAD临床试验仍在进行中，我们期待在2024年第一季度共享第二批研究的顶线数据。

The Phase 1b MAD study is a double-blind, placebo-controlled trial evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics (PK/PD) of RGLS8429 in adult patients with ADPKD. The study will evaluate RGLS8429 treatment across three different dose levels, including measuring changes in polycystins, height-adjusted total kidney volume (htTKV), cyst architecture, and overall kidney function.

1b期MAD研究是一项双盲，安慰剂对照试验，评估RGLS8429在成人ADPKD患者中的安全性，耐受性，药代动力学和药效学（PK/PD）。该研究将评估三种不同剂量水平的RGLS8429治疗，包括测量多囊蛋白的变化，高度调整的总肾体积（htTKV），囊肿结构和整体肾功能。

The second cohort is being dosed at 2 mg/kg of RGLS8429 or placebo every other week for three months. No issues were identified in cohort two based on the review of all available blinded safety data, allowing advancement to cohort three. The safety review incorporated available data from all 12 patients in the second cohort including several who had completed the dosing schedule.

第二组正在每隔一周以2mg/kg的RGLS8429或安慰剂给药三个月。基于对所有可用的盲法安全性数据的审查，在第二组中没有发现任何问题，允许推进到第三组。安全性评估纳入了第二队列中所有12名患者的可用数据，其中包括几名完成给药时间表的患者。

Patients in the third cohort will receive 3 mg/kg of RGLS8429 or placebo every other week for three months. .

第三队列中的患者将每隔一周接受3mg/kg的RGLS8429或安慰剂，持续三个月。 .

About ADPKD Autosomal Dominant Polycystic Kidney Disease (ADPKD), caused by mutations in the PKD1 or PKD2 genes, is among the most common human monogenic disorders and a leading cause of end-stage renal disease. The disease is characterized by the development of multiple fluid filled cysts primarily in the kidneys, and to a lesser extent in the liver and other organs.

由PKD1或PKD2基因突变引起的ADPKD常染色体显性多囊肾病（ADPKD）是最常见的人类单基因疾病之一，也是终末期肾病的主要原因。该疾病的特征是主要在肾脏中形成多个充满液体的囊肿，而在肝脏和其他器官中则较小。

Excessive kidney cyst cell proliferation, a central pathological feature, ultimately leads to end-stage renal disease in approximately 50% of ADPKD patients by age 60. Approximately 160,000 individuals are diagnosed with the disease in the United States alone, with an estimated global prevalence of 4 to 7 million..

肾囊肿细胞过度增殖是一种主要的病理特征，到60岁时，约有50%的ADPKD患者最终导致终末期肾脏疾病。仅在美国就有大约160000人被诊断出患有这种疾病，估计全球患病率为400万至700万。。

About RGLS8429 RGLS8429 is a novel, next generation oligonucleotide for the treatment of ADPKD designed to inhibit miR-17 and to preferentially target the kidney. Administration of RGLS8429 has shown robust data in preclinical models, where clear improvements in kidney function, size, and other measures of disease severity have been demonstrated along with a superior pharmacologic profile in preclinical studies compared to Regulus' first-generation compound, RGLS4326.

关于RGLS8429 RGLS8429是用于治疗ADPKD的新型下一代寡核苷酸，其设计用于抑制miR-17并优先靶向肾脏。RGLS8429的给药在临床前模型中显示出稳健的数据，其中与Regulus的第一代化合物RGLS4326相比，已经证明肾功能，大小和其他疾病严重程度测量的明显改善以及临床前研究中的优异药理学特征。

Regulus announced completion of the Phase 1 SAD study in September 2022. The Phase 1 SAD study demonstrated that RGLS8429 has a favorable safety and PK profile. RGLS8429 was well-tolerated with no serious adverse events reported and plasma exposure was approximately linear across the four doses tested and is similar to the PK data from the first-generation compound.

Regulus宣布于2022年9月完成第一阶段SAD研究。1期SAD研究表明RGLS8429具有良好的安全性和PK特性。RGLS8429耐受性良好，未报告严重不良事件，血浆暴露在所测试的四个剂量中近似线性，与第一代化合物的PK数据相似。

In the Phase 1b MAD study Regulus announced both top line data from the first cohort of patients, and completion of enrollment for the second cohort of patients in September 2023. After review of all available safety data, Regulus has advanced to the third cohort where dosing has begun and patients will receive 3 mg/kg of RGLS8429 or placebo every other week for three months..

在第1b阶段，MAD研究Regulus公布了第一批患者的一线数据，并于2023年9月完成了第二批患者的入选。在审查了所有可用的安全性数据后，Regulus已进入第三组，开始给药，患者将每隔一周接受3 mg/kg RGLS8429或安慰剂，持续三个月。。
