Secondary Outcome Measures

Adjusted Mean Change From Baseline in Hair Growth Assessed by TAHC in the Vertex at Week 12 [ Time Frame: Baseline and Week 12 ] The change from baseline in the TAHC within a 1 cm^2 of baldness area at Week 12, were assessed by macro photographic techniques analysis. The Investigator selected a target area in the anterior leading edge of the vertex thinning area. A small dot tattoo was placed in the center of the circle of the clipped hairs. Using the tattoo as a reference point, the circular area was photographed and a 1 cm^2 circular area within the target area was analysed. Change is the adjusted mean of Week 24 minus baseline.The analysis uses a covariance pattern model adjusted for treatment group, center, visit and treatment-by-visit interaction as fixed effects and baseline hair count as a covariate with an unstructured covariance structure.



Adjusted Mean Change From Baseline in Target Area Hair Width (TAHW) in the Vertex at Weeks 12 and 24 [ Time Frame: Baseline, Week 12 and Week 24 ] The change from baseline in the TAHW within a 1 cm^2 of baldness area at Weeks 12 and 24, were assessed by macro photographic techniques analysis. The Investigator selected a target area in the anterior leading edge of the vertex thinning area. A small dot tattoo was placed in the center of the circle of the clipped hairs. Using the tattoo as a reference point, the circular area was photographed and a 1 cm^2 circular area within the target area was analysed. Change is the adjusted mean of Weeks 12 and 24 minus baseline, respectively.The analysis uses a covariance pattern model adjusted for treatment group, center, visit and treatment-by-visit interaction as fixed effects and baseline hair count as a covariate with an unstructured covariance structure.



Adjusted Mean Overall Male Hair Growth Questionnaire (MHGQ) Score as Assessed by the Participant at Weeks 12 and 24 [ Time Frame: Week 12 and Week 24 ] Participants assessed their scalp hair using a validated, self-administered MHGQ, which was given in their language. The self-administered MHGQ overall score assessed using the following 5-point scale: 1 = very satisfied, 2 = satisfied, 3 = neutral (neither satisfied nor dissatisfied), 4 = dissatisfied, 5 = very dissatisfied. A higher score indicated a worse outcome. The questionnaire was administered to eligible participants to subjectively measure their perception of hair growth. A higher score indicated a worse outcome.



Adjusted Mean Change From Baseline in Participants Hair Growth/Loss Assessed for the Vertex by Investigator at Weeks 12 and 24 [ Time Frame: Baseline, Week 12 and Week 24 ] The local Investigator assessed change in hair growth from Baseline to Week 12 and from Baseline to Week 24, using a 7-point scale. The evaluation was done by the Investigator or designee, by comparing the global vertex view photograph obtained at baseline visit with the participants actual scalp at 12 and 24 weeks. For the purpose of assessment of changes in hair growth by Investigators screening visits (where global photos were taken) were used as Baseline. The change from Baseline in hair growth was assessed using the following 7-point scale: -3 = greatly decreased, -2 = moderately decreased, -1 = slightly decreased, 0 = no change, +1 = slightly increased, +2 = moderately increased, +3 = greatly increased. The analysis uses a covariance pattern model adjusted for treatment group, center, visit and treatment-by-visit interaction as fixed effects with an unstructured covariance structure.



Adjusted Mean Change From Baseline in Participants Hair Growth/Loss at Weeks 12 and 24, Assessed for the Vertex by Blind Assessor [ Time Frame: Baseline, Week 12 and Week 24 ] An independent blinded assessor was responsible for evaluating, under blinded conditions, the screening global photographs of the target area for all participants. They evaluated the eligibility of each participants according to the clinical inclusion criteria. The independent blinded assessor assessed the change of the hair growth from Baseline to Week 12 and from Baseline to Week 24, using a 7-point scale: -3 = greatly decreased, -2 = moderately decreased, -1 = slightly decreased, 0 = no change, +1 = slightly increased, +2 = moderately increased, +3 = greatly increased. This assessment was performed by comparing the global photographs obtained at screening visit with those subsequently obtained at Weeks 12 and 24. The analysis uses a covariance pattern model adjusted for treatment group, center, visit and treatment-by-visit interaction as fixed effects with an unstructured covariance structure.



Adjusted Mean International Index of Erectile Function (IIEF-2) Scores at Weeks 4, 8, 12 and 24 [ Time Frame: Weeks 4, 8, 12 and 24 ] The 15-question IIEF-2 Questionnaire (Sexual Function Questionnaire) was used to evaluate any changes in sexual function and activity, at Weeks 4, 8, 12 and 24. A score of 0-5 is awarded to each of the 15 questions that examine the 4 main domains of male sexual function: erectile function, orgasmic function, sexual desire and intercourse satisfaction. Erectile function domain has 6 questions with the score for domain range from 0-30. Orgasmic function domain has 2 questions with the score for domain range from 0-10. , Sexual desire function domain has 2 questions with the score for domain range from 0-10. Intercourse satisfaction function domain has 3 questions with the score for domain range from 0-15. Overall Satisfaction domain has 2 questions with the score for domain range from 0-10. A higher score indicated a worse outcome in that domain.



Local Tolerability as Assessed by Incidence Rate of Skin Irritation Event Via Severity Score for Skin Irritation Scale [ Time Frame: Baseline to Week 24 ] Local tolerability at the application site was assessed to rate the severity of any skin irritation. The Investigator used the Severity score for skin Irritation scale to assess local tolerability. The dermal response and other effects indicative irritation responses were recorded at time of examination. Anything other than "No evidence of irritation" under Dermal Response was considered as a Dermal Response Skin Irritation event. Anything other than "No other effects" under Other Effects was considered as an Other Effects of Skin Irritation event. The event incidence rate is calculated as the number of events interest divided by total personal time in years.
