Primary outcomes

  1. Change From Study Baseline in the Daily Normalized Daytime Average Number of Urinary Incontinence Episodes in Treatment Cycle 1

    Time frame: Study Baseline (Prior to Day 1 in Study 120) to 2 consecutive days in the week prior to Week 6 in Treatment Cycle 1

    Urinary incontinence was defined as involuntary loss of urine as recorded by the participant in a bladder diary during 2 consecutive days in the week prior to the study visit (normalized to a 12 hour daytime period). Daytime is defined as the time between waking up to start the day and going to bed to sleep for the night. The number of daily daytime incontinence episodes were averaged during the 2-day period. A negative change from Baseline indicates improvement. Data are summarized under the respective treatments that participants received in the corresponding treatment cycle.

  2. Change From Study Baseline in the Daily Normalized Daytime Average Number of Urinary Incontinence Episodes in Treatment Cycle 2

    Time frame: Study Baseline (Prior to Day 1 in Study 120) to 2 consecutive days in the week prior to Week 6 in Treatment Cycle 2

    Urinary incontinence was defined as involuntary loss of urine as recorded by the participant in a bladder diary during 2 consecutive days in the week prior to the study visit (normalized to a 12 hour daytime period). Daytime is defined as the time between waking up to start the day and going to bed to sleep for the night. The number of daily daytime incontinence episodes were averaged during the 2-day period. A negative change from Baseline indicates improvement. Data are summarized under the respective treatments that participants received in the corresponding treatment cycle.

  3. Change From Study Baseline in the Daily Normalized Daytime Average Number of Urinary Incontinence Episodes in Treatment Cycle 3

    Time frame: Study Baseline (Prior to Day 1 in Study 120) to 2 consecutive days in the week prior to Week 6 in Treatment Cycle 3

    Urinary incontinence was defined as involuntary loss of urine as recorded by the participant in a bladder diary during 2 consecutive days in the week prior to the study visit (normalized to a 12 hour daytime period).

Secondary outcomes

  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Treatment Emergent Adverse Events (STEAEs)

    Time frame: First injection on Day 1 in Study 120 through completion of Study 121 (Up to 108 weeks)

    An adverse event is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal (investigational) product, whether or not related to medicinal (investigational) product. A serious adverse event (SAE) is any AE that resulted in death, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, life threatening, a congenital anomaly/birth defect, or an important medical event. A TEAE or STEAE is defined as any new AE or worsening of an existing condition after initiation of treatment. Data are summarized under the respective treatments that participants received in the corresponding treatment cycles.
