This is a multicenter study to evaluate the efficacy and safety of 2 different doses of DR-3001. For eligible subjects the duration of the study will be approximately 20 weeks; this will consist of a 4-week screening period, a 12-week treatment period and a 4-week follow-up period. Subjects will have physical and laboratory exams, including blood draws at each scheduled visit. Subjects will be required to insert a vaginal ring (replacing it every 4 weeks) and to keep a daily record of their toilet voids (including time,type and volume) for 3 days at several specified time points.

Primary Outcome Measures:
  • Change in total weekly number of incontinence (urge and stress)episodes [ Time Frame: Baseline to end-of-treamtent (Week 12/Early withdrawal) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change in average daily urinary frequency and average void volume [ Time Frame: Baseline to end-of-treamtent (Week 12/Early withdrawal) ] [ Designated as safety issue: No ]
  • Proportion of subjects with no incontinence episodes recorded in the final 3-day diary [ Time Frame: Final 3-day diary ] [ Designated as safety issue: No ]
  • 3 subject-reported outcome measures: visual analogue scale of OAB symptoms, Urogenital Distress Inventory, Incontinence Impact Question [ Time Frame: Baseline to end-of-treatment (Week 12/Early Withdrawal) ] [ Designated as safety issue: No ]
  • Adverse events (AEs) reported by subjects or identified by the investigator [ Time Frame: Basline to end-of-treatment (Week 12/Early Withdrawal) ] [ Designated as safety issue: Yes ]
