Placebo injection is made up of sodium chloride (0.9 mg). 10 mL of the injection will be injected at 20 sites (0.5 mL at each site) in the detrusor muscle, spaced approximately 1 cm apart. The injection will be administered under local anesthesia, via cystoscopy. Permitted anesthesia options for cystoscopy are intraurethral lidocaine (or similar) gel, and for treatment administration, installation of 1-2% lidocaine (or similar anesthetic) into the bladder.

Subjects will use prophylactic antibiotic therapy approved for the indication of UTIs, at the discretion of the investigator, with the exception of those in the class of aminoglycosides. The therapy will begin 1 to 3 days prior to the administration of study treatment, and continue for 1 to 3 days following the treatment.

The bladder diary is a self-reporting tool to record subject's data on micturition. Subjects will enter data in the diary over 3 consecutive days. During Screening, data will be collected within 28 days prior to first treatment. During treatment periods, data will be collected within a week prior to each scheduled visit. The bladder diary will capture the following information: 1) Date and time of urinary episode, 2) episodes of micturition, 3) episodes of urinary incontinence, 4) episodes of urgency, 5) intensity of urgency, 6) episodes of nocturia, 7) use of CIC, and 8) urine volume. Diary data will not be collected when a subject experiences symptoms of a UTI.

The KHQ will assess the impact of urinary incontinence on QOL. It is a questionnaire with 21 items and the following 9 domains: 1) General health, 2) Incontinence impact, 3) Role limitations, 4) Physical limitations, 5) Social limitations, 6) Personal relationships, 7) Emotion, 8) Sleep/energy, 9) Severity measure. The items are answered by subjects themselves, and scores are summated using a defined algorithm.

The OABSS will comprehensively assess symptoms of OAB, such as frequency of micturition, nocturia, urinary urgency, and urge incontinence. It consists of 4 questions which will be responded by subjects themselves, by selecting the most appropriate answer for each question.

The TBS consists of one question ("My condition has"), to which the subject will answer by selecting one of the following responses: greatly improved, improved, not changed, worsened. The TBS will assess treatment benefit of GSK1358820.

Participants were instructed to enter data in a bladder diary over 3 consecutive days within a week prior to each scheduled visit (or within 28 days prior to Day 1), excluding the day of visit (this period was called the '3-day diary collection period').

Baseline is the latest pre-dose 3-day diary assessment which has at least one valid diary day. Change from Baseline was calculated as any visit value minus Baseline value.

Participants were considered for re-treatment beginning at the Week 12 visit following the initial treatment or the Week 12 visit following any re-treatment. Qualification criteria was; participants must have initiated request for re-treatment, participants experienced >=2 episodes of urinary urgency incontinence, with no more than one urgency incontinence-free day, post-void residual (PVR) urine volume must have been <200 milliliter; investigator deemed re-treatment appropriate. Time to the participant's first qualification for 2nd treatment from the day of 1st treatment was calculated as the earliest date when participants fulfilled the qualification for retreatment criteria minus the day of first treatment plus 1.

KHQ is a 21 item questionnaire, consisting of 9 domains: General health (GH) (1[Very good] to 5[Very poor]), Incontinence impact (Int Imp) (1[Not at all] to 4[A lot]), Role Limitations (RL) (1[Not at all] to 4[A lot]), Physical limitations (PL) (1[Not at all] to 4[A lot]), Social limitations (SL) (0[not applicable] to 4[A lot]), Personal relationships (PR) (0[Not applicable] to 4[A lot]), Emotions (1[Not at all] to 4[Very much]), Sleep/ energy (S/ E) (1[Never] to 4[All the time]) and Severity/Coping (S/ C) (1[Never] to 4[All the time]). Domain score for GH was calculated as score of one item minus 1/4x100; Int Imp: score of one item minus 1/3x100; RL, PL, PR, S/ E: summed scores of 2 items minus 2/6x100; SL, Emotions: summed scores of 3 items minus 3/9x100; S/ C: summed scores of 5 items minus 5/15x100.

Treatment benefit of GSK1358820 was assessed with TBS ranging from 1(Greatly improved) to 4 (Worsened). This questionnaire consists of 4 answers to 1 question by considering current condition of participants (urinary problems, urinary incontinence) compared to condition before participants received any study treatment in this trial. Positive treatment response was defined as score of either 1 or 2 (representing 'greatly improved' or 'improved').

Symptoms of frequency, nocturia, urinary urgency, and urge incontinence were assessed. OABSS questionnaire consisted of 4 questions: number of times participants urinate from waking in the morning until sleeping at night, ranging from 0 (<=7 times) to 1 (>=15 times); number of times participants wake up to urinate from sleeping at night until waking in the morning, ranging from 0 (0 times) to 3 (>=3 times); number of times for sudden desire to urinate, ranging from 0 (Not at all) to 5 (5 times a day or more); number of times of urine leakage, ranging from 0 (Not at all) to 5 (5 times a day or more). OABSS total score was calculated as the sum of scores for above 4 questions. The range of total score of OABSS was 0 to 15 with higher score indicating, more severity of symptoms. Baseline is the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was calculated as any visit value minus Baseline value.

Blood samples were collected for analysis of following clinical chemistry parameters; Albumin, Alkaline Phosphatase (Alk Phosp), Alanine Amino Transferase (ALT), Aspartate Amino Transferase (AST), Direct Bilirubin (Bil), Total Bil, Calcium, Chloride, Creatinine, Glucose, Potassium, Sodium, Total Protein (T Protein), Urea/blood urea nitrogen (BUN) and Uric acid. Participants were counted in the worst case category that their value changes to (Low, Normal or High), unless there is no change in their category. Participants whose value category was unchanged (e.g. High to High) or whose value became normal, are recorded in the To Normal or No Change category. Participants were counted twice if the participant had values that changed 'To Low' and 'To High', so the percentages may not add to 100 percent. Baseline is the latest pre-dose assessment with a non-missing value, including those from unscheduled visits.

Single 12-lead ECGs were obtained at indicated time point during the study using an ECG machine that automatically calculates the heart rate and measures PR, QRS and QT interval. QT interval corrected for heart rate (QTc) value is machine-read or manually over-read. Baseline is the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Clinically significant (CS) and not clinically significant (NCS) abnormal ECG findings have been presented. CS abnormal findings are those which are not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition.
