Number of Participants With Treatment-emergent Adverse Events (TEAEs) During the DB Treatment Period (Stage 1) |
For Stage 1, the primary endpoint was safety during the DB treatment period as assessed by the incidence of adverse events (AEs). An AE was the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. An undesirable medical condition could have been symptoms, signs or abnormal results of an investigation. A TEAE was an event with start date on or after the date of the first investigational medicinal product (IMP). Relatedness to treatment was assessed by the investigator. TEAEs of special interest included events suggesting a possible remote spread of effect of the toxin, events related to urinary incontinence or faecal incontinence and events assessed as a potential hypersensitivity reaction. Results for this outcome are reported as the number of participants experiencing at least one TEAE in each specified category. |

Mean Change From Baseline in Vaginal Dilator Induced Pain as Reported on an 11-point Numeric Rating Scale (NRS) During the DB Treatment Period at Week 6 and Week 12 (Stage 1) |
For the dilator test, a vaginal dilator was used by the investigator to provoke pain to allow assessment of vestibular pain intensity in each participant. Participants rated their pain using an 11-point NRS ranging from 0 to 10, where 0 was no pain and 10 was the worst possible pain. Higher scores indicate a worse outcome. The dilator test was used to assess the change from Baseline in the vaginal dilator induced pain (using the DMTS reported at Baseline). Baseline was defined as the last value available prior to the first study IMP treatment administration. Results for this outcome are reported as change from Baseline during the DB treatment period at Week 6 and Week 12. |

Mean Change From Baseline in the DTMS During the DB Treatment Period at Week 6 and Week 12 (Stage 1) |
For the dilator test, a set of 8 vaginal dilators of increasing diameter (#1 being the smallest and #8 being the largest) were used by the investigator to provoke pain to allow assessment of vestibular pain intensity in each participant. Based on the subjective pain threshold, the largest sized dilator that the participant accepted/tolerated for the test, was defined as the DMTS. Participants rated their pain using an 11-point NRS ranging from 0 to 10, where 0 was no pain and 10 was the worst possible pain. Higher scores indicate a worse outcome. Baseline was defined as the last value available prior to the first study IMP treatment administration.

Mean Change From Baseline in the Composite Score for the Vaginal Dilator Induced Pain and Dilator Size During the DB Treatment Period at Week 6 and Week 12 (Stage 1) |
For the dilator test, a set of 8 vaginal dilators of increasing diameter (#1 being the smallest and #8 being the largest) were used by the investigator to provoke pain to allow assessment of vestibular pain intensity in each participant. The composite score for the vaginal dilator induced pain and dilator size was the sum of all pain measurements across the full range of dilator sizes. For any dilator size that was beyond the DMTS, the pain score was 10. There was to be at least 6 pain scores (recorded by the investigator) to calculate the composite score. Participants rated their pain using an 11-point NRS ranging from 0 to 10, where 0 was no pain and 10 was the worst possible pain. Higher scores indicate a worse outcome. Baseline was defined as the last value available prior to the first study IMP treatment administration. Results for this outcome are reported as change from Baseline in the composite score for the dilator test during the DB treatment period at Week 6 and Week 12. |
