LA JOLLA, Calif., Feb. 17, 2016 /PRNewswire/ -- Regulus Therapeutics Inc. (NASDAQ:RGLS), a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today announced interim results from one of the company's ongoing Phase II studies of RG-101 for the treatment of Hepatitis C Virus infection (HCV). The study was designed to evaluate a shortened, four-week treatment regimen containing a subcutaneous administration of 2 mg/kg of RG-101 at Day 1 and Day 29, 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® arm, n=27, Olysio® arm, n=27, Daklinza™ arm, n=25). Thirty-eight patients have been evaluated through 8 weeks of follow up. Ninety-seven percent of those patients (37/38) had HCV RNA viral load measurements below the limit of quantification. To date, RG-101 has been generally well tolerated with the majority of adverse events considered mild or moderate, and with no study discontinuations. For those patients through 12 weeks of follow-up, 100% remained below the limit of quantification (14/14). The primary endpoint analysis (12 week follow up) for all 79 patients in the study are anticipated to be reported in late Q2 2016.
Die leberspezifische Mikro-RNA miR-122 sorgte bereits vor einigen Jahren als vielversprechendes neues Angriffsziel für die Entwicklung eines HCV-spezifischen Medikaments für großes Aufsehen (11). Das damals eingesetzte anti-miR-122-Wirkstoff Miravirsen wurde jedoch von Roche bislang (oder endgültig?) nicht über Phase-II hinaus weiterentwickelt.
Entsprechend groß war nun das Interesse an der GalNAc-konjugierten anti-miR-122-Substanz namens RG-101 der Firma Regulus. Nach einmaliger subkutaner Gabe in unterschiedlicher Dosis lag die HCV-RNA bei insgesamt 6/28 Patienten (1x GT1, 2x GT3 und 3x GT4) noch 28 Wochen später unter der Nachweisgrenze (12). Weitere Studienergebnisse zur Kombination aus RG-101 mit bereits zugelassenen DAAs werden in Kürze erwartet.
