Scientific leadership strengthened with the appointment of Amin Kamel, Ph.D., as Vice President, Drug Metabolism and Pharmacokinetics (DMPK)

SAN DIEGO, Aug. 11, 2022 /PRNewswire/ -- Regulus Therapeutics Inc. (Nasdaq: RGLS), a biopharmaceutical company focused on the discovery and development of innovative medicines targeting microRNAs (the "Company" or "Regulus"), today reported financial results for the second quarter ended June 30, 2022 and provided a corporate update. 

"This has been an exciting quarter, which culminated in the achievement of multiple milestones. We continue to make steady progress with RGLS8429, evidenced by the dosing of the first subject in our Phase 1 SAD study," commented Jay Hagan, CEO of Regulus. "Moreover, we are pleased to have Dr. Amin Kamel join the Regulus team at this pivotal moment. We are proud of the work our team is doing to advance our novel therapeutic candidate for ADPKD patients, and we look forward to providing additional updates on progress in the coming quarters."

Program Updates

RGLS8429 for ADPKD: In early June 2022, the Company announced the dosing of the first subject in its Phase 1 SAD study of RGLS8429 for the treatment of ADPKD. The study will assess the safety, tolerability, and pharmacokinetics of RGLS8429 in healthy volunteers. The Company subsequently plans to initiate a Phase 1b multiple ascending dose (MAD) study to assess safety, tolerability, and pharmacokinetics of RGLS8429 in adult patients with ADPKD, and evaluate the efficacy of RGLS8429 treatment across three different dose levels measuring changes in polycystins, cystic kidney volume (htTKV), and overall kidney function.

In late June, the Company announced that FDA had granted ODD to RGLS8429 for the treatment of ADPKD. The FDA's Office of Orphan Products Development grants orphan designation status to drugs and biologics that are intended for the safe and effective treatment, diagnosis or prevention of rare diseases, or conditions that affect fewer than 200,000 people in the U.S. Orphan designation status is intended to facilitate drug development for rare diseases and may provide several benefits to drug developers, including financial incentives, to support clinical development and the potential for up to seven years of market exclusivity in the U.S. upon regulatory approval.

Corporate Highlights

Expanded Team: In June 2022, the Company announced the appointment of Amin Kamel, Ph.D., as Vice President, DMPK. Most recently, Dr. Kamel was the Scientific Director, DMPK at Takeda, where he also served as a scientific advisor. Prior to Takeda, Dr. Kamel held positions at Biogen, Novartis, and Pfizer.

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 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.

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. Regulus is currently conducting a Phase 1 single-ascending dose study in healthy volunteers to assess safety, tolerability, and pharmacokinetics of RGLS8429. In June 2022, FDA granted ODD for RGLS849 for the treatment of ADPKD.
