LA JOLLA, Calif., March 2, 2017 /PRNewswire/ -- Regulus Therapeutics Inc. (Nasdaq: RGLS), a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today reported financial results for the fourth quarter and full year ended December 31, 2016 and provided a summary of corporate highlights and pipeline update.  

"2016 was a year of accomplishments and important key learnings that position us for meaningful advancements in our clinical and pre-clinical programs in 2017 and beyond. Based on these learnings, I am even more convinced that targeting microRNAs offer significant advancements in therapeutic potential for many diseases for which there are currently no or limited treatment options," said Paul Grint, M.D., President and Chief Executive Officer of Regulus.

Fourth Quarter 2016 Highlights

  • Initiated a Phase I MAD study for RG-012: Data from this study in healthy volunteers will provide additional PK and safety data and will be available in the second quarter 2017. The Phase II HERA study is expected to resume in the second half of 2017 following completion of the MAD study.
  • Announced two new clinical candidates at the Company's first R&D Day: RGLS5040 (anti-miR-17) for the treatment of cholestatic diseases; and RGLS4326 (anti-miR-27) for the treatment of autosomal dominant polycystic kidney disease (ADPKD). IND-enabling activities are currently underway. Regulus expects to file the INDs in the second half of 2017.
  • Attracted Key Talent: Dr. Timothy Wright joined Regulus in October as its Chief R&D Officer.

Pipeline Update

RG-012 for treatment in patients with Alport syndrome  

  • Today, Regulus announced that it has modified the Phase II RG-012 clinical development program in patients with Alport syndrome to accelerate patient enrollment and potentially achieve early proof of mechanism/proof of concept.  The Phase II program will include the HERA study, a randomized, double-blind, placebo-controlled 48-week study in 30 patients with rapid renal function decline. The objective of the HERA study will be to evaluate the safety and efficacy of RG-012 for the treatment of renal function decline in patients with Alport syndrome. In parallel, a separate Phase I/II renal biopsy study in Alport patients will be initiated to evaluate RG-012 tissue PK, target engagement of miR-21, and effects on downstream genomic markers of disease.  Both studies are anticipated to begin enrollment following the completion of the Phase I MAD study in Q2 2017.  Based on projected enrollment rates, data from the renal biopsy study are expected in Q4 2017 and interim data from HERA are expected in mid-2018.

RG-101 for the treatment of HCV

  • Today, Regulus reported top-line results from the primary endpoint analysis of its completed Phase II study of RG-101 in combination with 4 weeks of once/daily approved anti-viral agents Harvoni®, Olysio®, or Daklinza™.  The study enrolled 79 treatment naïve genotype 1 and 4 HCV patients (Harvoni® combination arm, n=27, Olysio® combination arm, n=27, Daklinza™ combination arm, n=25).  The results from this final analysis demonstrated significant virologic response through 48 weeks of follow-up:  RG-101 plus Harvoni demonstrated 100% SVR48; RG-101 plus Olysio demonstrated 77% SVR48; and RG-101 plus Daklinza™ demonstrated 84% SVR48. There were 10 relapses: six in the Olysio® combination arm (weeks 8, 20, 24 and 32); and four in the Daklinza™ combination arm (weeks 8, 12 and 24).   RG-101 in combination with four weeks of oral DAA therapy was generally well tolerated with the majority of adverse events (AEs) considered mild or moderate with no AE-related discontinuations.  Commonly reported AEs included fatigue, headache, and injection site reactions. There were four patients across all arms that experienced adverse events of asymptomatic transient hyperbilirubinemia (greater than or equal to two times the upper limit of normal). No cases met criteria for Hy's law. Over the course of the one-year study, five subjects reported serious adverse events (SAE).  As previously reported, there was a single SAE of jaundice in a patient at seven weeks in the Daklinza™ combination arm of the study.  Since the interim analysis in June 2016, there were two additional SAEs: one was a trauma-related knee injury; and the other was an upper respiratory infection.
  • In January, the Company reported that it received written communication from the FDA that the clinical development program from RG-101 remains on clinical hold. The FDA has requested the final safety and efficacy data from all on-going RG-101 pre-clinical and clinical studies before reconsidering the clinical hold. These data are anticipated to be available in Q4 2017.

RGLS5040 for the treatment of cholestatic diseases

  • IND-enabling activities are currently underway, and an IND filing is currently on track for the second half of 2017.

RGLS4326 for the treatment of ADPKD

  • IND-enabling activities are currently underway, and an IND filing is currently on track for the second half of 2017.
