Announced positive topline data from the first cohort of patients in Phase 1b Multiple-Ascending Dose (MAD) Clinical Trial of RGLS8429 for the Treatment of Autosomal Dominant Polycystic Kidney Disease (ADPKD)
Completed enrollment in the second cohort of the Phase 1b MAD Clinical Trial of RGLS8429 for the Treatment of ADPKD
First patient dosed in the third cohort of the Phase 1b MAD Clinical Trial of RGLS8429 for the Treatment of ADPKD
"This has been yet another exciting quarter for Regulus as our Phase 1b MAD study of RGLS8429 for the treatment of ADPKD continues to advance. In September, we announced positive topline data for the first cohort. We have since completed enrollment in our second cohort, and, in addition, we dosed the first patient in the third cohort in early November," said Jay Hagan, CEO of Regulus. "We enjoyed having the opportunity to describe the unique mechanism and benefits of RGLS8429 during our investor event that took place on September 6th. I want to extend another big thank you to Drs. Peter Harris, Tim Kline, Vishal Patel, and Alan Yu for their participation and insight. We remain focused on our goal of bringing life-changing therapeutics to patients with orphan kidney diseases, and we are looking forward to continuing to share study and data updates as they become available, including cohort two topline data in the first quarter of 2024."
Program Updates
RGLS8429 for ADPKD: The Company held a virtual R&D Day on September 6, 2023, where the executive team joined academic leaders in ADPKD to discuss RGLS8429 along with the current unmet need in ADPKD, the role of genetics and polycystin in driving disease pathology, and the historical preclinical and clinical data that support targeting miR-17 as a therapeutic approach.
In September 2023, the Company announced the completion of enrollment of the second cohort in the Phase 1b MAD study of RGLS8429 for the treatment of ADPKD. The Phase 1b MAD study is a double-blind, placebo-controlled trial evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics 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, cyst architecture, and overall kidney function. The second cohort is being dosed at 2 mg/kg of RGLS8429 or placebo every other week for three months.
The Company also shared positive topline data from the first cohort of patients in the phase 1b MAD study, in which patients were dosed at 1 mg/kg of RGLS8429 or placebo every other week for three months. Results showed increases in both PC1 and PC2 biomarkers. The mean PC1 level increase was statistically significant, with 36
In October 2023, the Company announced that, after a review of all available safety data in cohort two, it advanced to the third cohort in the Phase 1b MAD study. Shortly after, in November 2023, the Company announced dosing of the first patient in the third cohort. Patients in the third cohort are being dosed at 3mg/kg of RGLS8429 or placebo every other week for three months.

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. Excessive kidney cyst cell proliferation, a central pathological feature, ultimately leads to end-stage renal disease in approximately
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. 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. 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.
