- Brief Summary
This study aims to evaluate whether PF-06372865 is safe and effective in the treatment of sub-optimally controlled symptoms of generalized anxiety disorder during two 4-week treatment periods using a Sequential Parallel Comparison Design (SPCD).

- Primary Outcome Measures
Name Time Method Hamilton Anxiety Rating Scale (HAM-A) Total Scores at Week 4 During Stage 1 and at Week 8 During Stage 2 Stage 1: Week 4, Stage 2: Week 8 The HAM-A scale was a clinician rated interview scale designed to measure the signs and symptoms of anxiety. It had 14-items to rate the intensity of psychic and somatic anxiety on a 5-point severity scale. Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 56 (very severe), where lower scores indicates less anxiety.

It had 14-items to rate the intensity of psychic and somatic anxiety on a 5-point severity scale. Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 56 (very severe), where lower scores indicates less anxiety.

Name Time Method Change From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Scores at Week 1, Week 2 and Week 3: Stage 1 Week 1, 2, 3 The HAM-A scale was a clinician rated interview scale designed to measure the signs and symptoms of anxiety. It had 14-items to rate the intensity of psychic and somatic anxiety on a 5-point severity scale. Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 56 (very severe), where lower scores indicates less anxiety.
Percentage of Responders of Total Hamilton Anxiety Rating Scale (HAM-A): Stage 1 and Stage 2 Stage 1: Week 4, Stage 2: Week 8 A responder was defined as a participant with \>= to 50 percent decrease in their total HAM-A score from baseline to the last week in the stage (Week 4 in Stage 1, Week 8 in Stage 2). The HAM-A scale was a clinician rated interview scale designed to measure the signs and symptoms of anxiety. It had 14-items to rate the intensity of psychic and somatic anxiety on a 5-point severity scale. Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 56 (very severe), where lower scores indicates less anxiety. Percentage of responders of total HMA scale were reported.
Change From Baseline in Clinical Global Impression -Severity (CGI-S) Scale Score at Week 1, 2, 3, 4 in Stage 1 and Week 5, 6, 7, 8 in Stage 2 Stage 1 (S1): Baseline (Day 1), Week 1 (W1), 2 (W2), 3 (W3), 4 (W4) and Stage 2 (S2): Baseline (Day 28), Week 5 (W5), 6 (W6), 7 (W7), 8 (W8) The CGI-S consisted of a single 7-point rating score of illness severity, was completed by a clinician. Raters selected one response based on the following question, "Considering your total clinical experience with that particular population, how mentally ill was your participant at that time?" Scores were: 1 (normal, not ill at all), 2 (borderline mentally ill), 3 (mildly ill), 4 (moderately ill), 5 (markedly ill) 6 (severely ill) or 7 (among the most severely ill participants). Higher scores indicate more severity.
Plasma Concentration Versus Time Summary of PF-06372865: Stage 1 Pre-dose (0 hour), 2, 4, 10 hours post dose on Day 1 of Week 2, 3, 4 Concentration versus time summary was calculated by setting concentration values below the lower limit of quantification (LLOQ =0.0100 nanogram per milliliter (ng/mL) to zero. Summary statistics were not to be presented if number of observations above lower limit of quantification (NALQ) = 0.
Plasma Concentration Versus Time Summary of PF-06372865: Stage 2 Pre-dose (0 hour), 2, 4, 10 hours post dose on Day 1 of Week 6, 7, 8 Concentration versus time summary was calculated by setting concentration values below the lower limit of quantification (LLOQ =0.0100 ng/mL) to zero. Summary statistics were not to be presented if number of observations above lower limit of quantification (NALQ) =0.
Change From Baseline in the Hamilton Anxiety Rating Scale (HAM-A): Somatic Subscale Score at Week 1, 2, 3, 4, 5, 6, 7, 8 Stage 1 (S1): Baseline (Day 1), Week 1 (W1), 2 (W2), 3 (W3), 4 (W4) and Stage 2 (S2): Baseline (Day 28), Week 5 (W5), 6 (W6), 7 (W7), 8 (W8) The HAM-A scale was a clinician interview-administered scale designed to measure the signs and symptoms of anxiety. It had 14-items to rate the intensity of psychic and somatic anxiety on a 5-point severity scale. Somatic subscale of the HAM-A was the sum of 7 items. Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 28 (very severe), where lower scores indicates less anxiety.
Change From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Scores at Week 5, Week 6, Week 7 and Week 8: Stage 2 Week 5, 6, 7, 8 The HAM-A scale was a clinician rated interview scale designed to measure the signs and symptoms of anxiety. It had 14-items to rate the intensity of psychic and somatic anxiety on a 5-point severity scale. Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 56 (very severe), where lower scores indicates less anxiety.
Change From Baseline in Sheehan Disability Scale (SDS) Total Score and Social, Work, Family Subscale Scores: Stage 1 and Stage 2 Stage 1: Week 4, Stage 2: Week 8 SDS was a copyrighted, three question instrument designed to assess functional impairment associated with mental disorders in three domains: work impairment, social impairment, and impairment of family life or home responsibilities. Disability scores were reported for each of the questions (subscale scores range from 0 to 10) and a total disability score was calculated as the sum of scores for each question (total scores range from 0 to 30). Higher scores reflect greater impairment.
Change From Baseline in Clinical Global Impression - Improvement (CGI-I) Scale Score at Week 1, 2, 3, 4 in Stage 1 and Week 5, 6, 7, 8 in Stage 2 Stage 1 (S1): Baseline (Day 1), Week 1 (W1), 2 (W2), 3 (W3), 4 (W4) and Stage 2 (S2): Baseline (Day 28), Week 5 (W5), 6 (W6), 7 (W7), 8 (W8) CGI-I was a 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement was defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved), 4 (no change), 5 (minimally worse), 6 (much worse) or 7 (very much worse) on the scale. Higher score indicated more affected. Change is equal to score at observation minus score at baseline.

Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 28 (very severe), where lower scores indicates less anxiety.
Sheehan Disability Scale (SDS) Total Score and Social, Work, Family Subscale Scores at Baseline: Stage 1 and Stage 2 Stage 1: Baseline (Day 1 ), Stage 2: Baseline (Day 28) SDS was a copyrighted, three question instrument designed to assess functional impairment associated with mental disorders in three domains: work impairment, social impairment, and impairment of family life or home responsibilities. Disability scores were reported for each of the questions (subscale scores range from 0 to 10) and a total disability score was calculated as the sum of scores for each question (total scores range from 0 to 30). Higher scores reflect greater impairment.
Percentage of Participants With Remission of Total Hamilton Anxiety Rating Scale (HAM-A) Scores Stage 1: Week 1 up to Week 4 and Stage 2: Week 5 up to Week 8 Percentage of participants with HAM-A total score less than or equal to 7 in the last week of the Stage (Week 4 in Stage 1, Week 8 in Stage 2). The HAM-A scale was a clinician rated interview scale designed to measure the signs and symptoms of anxiety. It had 14-items to rate the intensity of psychic and somatic anxiety on a 5-point severity scale. Each item ranging from 0 (not present) to 4 (very severe) were summed up to give a total possible score of 0 (not present) to 56 (very severe), where lower scores indicates less anxiety.
