Other Events

On May 21, 2021, Regulus Therapeutics, Inc. (the “Company”) announced an incremental update from the first cohort of patients with ADPKD in its ongoing Phase 1b clinical trial of RGLS4326. The study is evaluating the safety, pharmacokinetics, and effects on pharmacodynamic biomarkers of multiple doses of RGLS4326 in patients with ADPKD. These data were presented at the Oppenheimer Rare & Orphan Disease Summit on May 21, 2021.

In the first cohort, nine patients were enrolled and received 1 mg/kg of RGLS4326 subcutaneously every other week for four doses. The mean increase in polycystins 1 and 2 at the end of study compared to baseline levels for all nine patients in the first cohort were 58% (p=.0004) and 38% (p=.026) respectively. Treatment with RGLS4326 was generally well-tolerated with no serious adverse events reported. All reported adverse events were mild and generally transient in nature. Regulus believes these data demonstrate that RGLS4326 engages the target miR-17 leading to increased expression of the PKD1 and PKD2 genes and the resultant increases in polycystins’ levels. Levels of polycystin 1 (PC1) and polycystin 2 (PC2) have previously been shown to inversely correlate with disease severity and are believed to be directly linked to the underlying genetic drivers of the disease.

On May 21, 2021, the Company posted a recording of the presentation to its website at http://ir.regulusrx.com/events. A copy of the investor presentation is attached as Exhibit 99.1 to this Current Report on Form 8-K.
