Number of Participants With Any Laboratory Value Shifts From Baseline at Any Time Post-baseline
Blood samples for the assessment of the indicated laboratory parameters were taken at the Baseline, Week 26 and Week 52 visits and the early withdrawal visit where applicable. The laboratory parameters included ALP, ALT, AST, total bilirubin, total protein, sodium, potassium, albumin, glucose, creatinine, urea/BUN, hemoglobin, hematocrit, red blood cell (RBC) count, platelet count, white blood cell (WBC) count, and prostate-specific antigen (PSA). A laboratory value (LV) that is within the normal range is considered normal. A LV that is above the upper limit of the normal range is considered high abnormal. A LV that is below the lower limit of the normal range is considered low abnormal. Number of participants with any LV shifts from BL at any time post-BL are presented for, normal at BL to abnormal; normal at BL to high; normal at BL to low; normal or low at BL to high; normal or high at BL to low.
Time frame: Baseline, Week 26 and 52 visits and/or early withdrawal visit
Population: ITT Population. Only participants with a normal BL and at least one post-BL LV are analysed. ITT Population (represented by n=X in the category titles).

Number of Participants With Change From Baseline in Breast Examination Results Any Time Post-Baseline Visit
A qualitative breast examination was performed at Baseline (Week 0), at the Week 26 Visit and at the Week 52 Visit (and at the early withdrawal visit, if applicable). Participants were assessed for presence (reported as yes) and absence (reported as no) of palpable breast tissue (PBT) or nipple tenderness (NT) and/or clinically significant (CS) PBT or NT at Baseline (BL), at each scheduled Post-BL assessment. Change from BL in breast examination results included the number of participants with change from 'no (N)' at BL to 'yes (Y)' at any Post-BL assessment for the presence of PBT or NT, and the number of participants with change from N at BL in CS to Y at any Post-BL assessment in CS for PBT and for NT. BL value of an assessment is defined as the latest assessment on or before the BL date (latest non-missing value of either the treatment start date or the randomization date).
Time frame: Baseline to Week 52
Population: ITT Population. Only those participants available at the specified time points were analyzed (represented by n=X in the category titles). Different participants may have been analyzed for different parameters, so the overall number of participants analyzed reflects everyone in the ITT Population.

Number of Participants With Drug-related, Treatment-emergent AEs and AE Leading to Premature Study Drug Discontinuation and Possible Suicidality-related Adverse Event (PSRAE)
An AE is considered drug-related if the relationship variable indicates so, or if the variable value is missing. Any AE with a start date on or after the treatment start date and on or before the last dose of treatment is considered on-treatment (treatment-emergent). This includes an AE with a missing onset date. Any AE which occurred, in the investigator's judgement and is possibly related to suicidality, is defined as possible suicidality-related adverse event (PSRAE). Suicidality was assessed by using the columbia-suicide severity rating scale (C-SSRS) as determined by the investigator. The C-SSRS captures occurrence, severity, and frequency of suicide-related thoughts and behaviors.

Change From Baseline in Quality of Life as Assessed by Dermatology Life Quality Index (DLQI) at Week 13, Week 26, Week 39, and Week 52
The DLQI is a 10-item validated measure developed specifically to assess quality of life (QoL) in participants with dermatological conditions. It assesses six domains: symptoms and feelings, daily activities, leisure, work ⁄school, personal relationships, and treatment. The DLQI total is the sum of 10 questions, each ranging from 0 (unanswered/not relevant,not at all) to 3 (very much). The higher the score, the greater the impairment of (QoL). Change from Baseline in DLQI scores is defined as the post-Baseline value minus the Baseline value. The Baseline value of an assessment is defined as the latest assessment on or before the Baseline date (latest non-missing value of either the treatment start date or the randomization date). The LOCF method for missing data was used by carrying forward the last non-missing post-Baseline assessment for participants with missing data and/or for participants who discontinued from the study.

Mean Change From Baseline (BL) in Target Area Hair Count Within a 2.54 Centimeter (cm) Diameter Circle at Week 26 and Week 52
Target area hair count is based on the nonvellus hair(\>= 30 micrometer\[μm\] in width) count within a target 2.54cm(1 inch) diameter circle at the vertex and was assessed by macrophotographic technique. A cosmetic ink dot was placed by means of a tattoo at BL on the scalp in the center of the circle as a marker to guide the placement of the hair count area at subsequent time points. If the ink dot faded between study visits, it was redone. For the macrophotography, hair was clipped before each photograph. Change from BL is defined as post-BL value minus BL value. The BL value is defined as the latest assessment on or before the BL date(latest non-missing value of either treatment start date or randomization date). The last observation carried forward(LOCF) method for missing data was used by carrying forward the last non-missing post-BL assessment value for participants with missing data and/or for participants who discontinued from the study.

Mean of Median Score for Panel Global Assessment of Improvement From Baseline to 26 Weeks and 52 Weeks for Vertex and Frontal Views
A central panel of 3 dermatologists independently assessed change in hair growth from Baseline to Week 26 and Week 52 using a 7-point scale: greatly decreased (-3), moderately decreased (-2), slightly decreased (-1), no change (0), slightly increased (1), moderately increased (2), and greatly increased (3). The median score, across the 3 panel members, is summarized. This assessment was performed by comparing the global photographs obtained at Baseline (Screening) with those subsequently obtained at Week 26 and Week 52. This assessment was made separately based on the global photography of the vertex and frontal views. The LOCF method for missing data was used for the assessment, if a participants was missing the Week 26 global photograph, but has a global photograph from an earlier assessment (i.e., a withdrawal visit), then that photograph was assessed during the panel review.

Number of Participants With the Indicated Change From Baseline (BL) in the Stage of Androgenic Alopecia (AGA) According to the Norwood-Hamilton Scale at 26 Weeks and 52 Weeks
The investigator/designee assessed the stage (Stage I to Stage VII) of AGA (i.e., male pattern baldness \[MPB\]) by utilizing the Norwood-Hamilton scale, used to measure the progression of MPB. Stage VII indicates worse balding than Stage I. Assessment was made by direct visual examination (aided by pictures) of the participant at Screening (Baseline), Week 26, and Week 52. v, vertex; most of the hair loss (commonly seen with advancing age) is on the vertex. a, type a variant; major features are (1) the entire anterior hairline border recedes in unison; (2) there is no simultaneous balding of the vertex. The number of participants with stage changes from Baseline are summarized. The LOCF method for missing data was used by carrying forward the last non-missing post-Baseline assessment for participants with missing data and/or for participants who discontinued from the study.
Time frame: Baseline, Week 26 and Week 52
Population: ITT Population. Only those participants available at the specified time points were analyzed (represented by n=X in the category titles). Different participants may have been analyzed at different time points, so the overall number of participants analyzed reflects everyone in the ITT population.
