Subjects who are currently taking a second antidepressant or antidepressant augmentation agent at a sub-therapeutic dose or for an inadequate duration at Screening, and can be discontinued from this agent before the Baseline visit (in the opinion of the Investigator), may be eligible for the study. 5. Is on a stable dose of anti-Parkinson's medication for 1 month prior to Screening 6. If the subject is female, she must be of non-childbearing potential or agree to use two methods of clinically acceptable contraception Exclusion Criteria: 1. Use of an antipsychotic within 3 weeks or 5 half-lives of Baseline (whichever is longer) 2. Had a myocardial infarction within the 6 months prior to Screening 3. Has a known personal or family history or symptoms of long QT syndrome 4. Evidence of severe or medically significant hepatic or renal impairment on laboratory tests as assessed by the Investigator or Medical Monitor 5. Has a history of PD psychosis, schizophrenia, or other psychotic disorder, or bipolar I or II disorder. 6. Actively suicidal at Visit 1 (Screening) or Visit 2 (Baseline) 7. Is pregnant or breastfeeding 8. Has previously been treated with pimavanserin or is currently taking pimavanserin 9. Has a sensitivity to pimavanserin or its excipients 10. Is judged by the Investigator or the Medical Monitor to be inappropriate for the study Additional inclusion/exclusion criteria apply. Subjects will be evaluated at screening to ensure that all criteria for study participation are met. |

| Primary | Change From Baseline to Week 8 in HAMD-17 (Hamilton Depression Scale -17 Items) Total Score | The HAMD-17 is a multiple-item questionnaire to assess the severity of depression, including items of mood, feelings of guilt, suicide ideation, insomnia, agitation or retardation, anxiety, weight loss, and somatic symptoms. Each of the 17 items is scored on a 3- or 5-point scale (depending on the item). The minimum total score is 0; the maximum total score is 52. A higher total score signifies more severe depression. | From baseline to Week 8 | |
| Secondary | Change From Baseline (CFB) in HAMD-17 Total Score at Weeks 2, 4, and 6 | The HAMD-17 is a multiple-item questionnaire to assess the severity of depression, including items of mood, feelings of guilt, suicide ideation, insomnia, agitation or retardation, anxiety, weight loss, and somatic symptoms. Each of the 17 items is scored on a 3- or 5-point scale (depending on the item). The minimum total score is 0; the maximum total score is 52. A higher total score signifies more severe depression. | 2, 4, and 6 weeks from baseline | |
| Secondary | Clinical Global Impression-Improvement (CGI-I) | The CGI-I is a clinician-rated 7-point scale to rate the improvement in the patient's depression at the time of assessment relative baseline. The CGI-I ranges from 1 (very much improved) to 7 (very much worse) | At Week 8 | |
| Secondary | Change From Baseline (CFB) in Clinical Global Impression-Severity (CGI-S) | The CGI-S is a clinician-rated 7-point scale to rate the severity of the patient's depression at the time of assessment. The CGI-S ranges from 1 (normal) to 7 (patient is among the most severely ill). | From baseline to Week 8 | |
| Secondary | Change From Baseline (CFB) in Scale of Outcomes in PD-Sleep Scale (SCOPA) Nighttime Sleep (NS)Score | The SCOPA-NS subscale addresses problems in nighttime sleep and consists of 5 items (sleep initiation, sleep fragmentation, sleep efficiency, sleep duration, early wakening). Each item has 4 response options (ranging from 0=not at all to 3=a lot). The SCOPA-NS score ranges from 0 to 15, with a higher score indicating more severe nighttime sleep problems. | From baseline to Week 8 | |
| Secondary | Change From Baseline (CFB) in SCOPA Daytime Sleepiness (DS) Score | The SCOPA-DS subscale addresses problems in daytime sleepiness and consists of 6 items (falling asleep unexpectedly, falling asleep peacefully, falling asleep watching TV/reading, falling asleep while talking to someone, having difficulty staying awake, whether falling asleep in the daytime is considered a Problem). Each item has 4 response options (from 0=never to 3=often). The SCOPA-DS subscale score ranges from 0 to 18, with a higher score indicating more severe DS problems. | From baseline to Week 8 | |
| Secondary | The Number (or Percentage) of Responders | The HAMD-17 is a multiple-item questionnaire to assess the severity of depression, including items of mood, feelings of guilt, suicide ideation, insomnia, agitation or retardation, anxiety, weight loss, and somatic symptoms. Each of the 17 items is scored on a 3- or 5-point scale (depending on the item). The minimum total score is 0; the maximum total score is 52. A higher total score signifies more severe Depression. Response was defined as =50% reduction from baseline in HAMD-17 total score. Patients without Week-8 score were counted as nonresponders. |
From baseline to Week 8 | |
| Secondary | Change From Baseline in EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) | The EQ-5D-5L is a standardized measure of health status. The questionnaire consists of 2 components: the EQ-5D-5L descriptive system and the EQ-5D-5L Visual Analogue scale (EQ-5D-5L VAS). The descriptive system consists of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression). Each dimension has 5 levels (from 1=no problem to 5=extreme Problems). The digits for the 5 dimensions are combined into a 5-digit code that describes the patient's health state, which is then converted into a single summary index value. Health state index scores generally range from less than 0 (where 0 is the value of a health state equivalent to dead; negative values representing values as worse than dead) to 1 (the value of full health), with higher scores indicating higher health utility. The EQ-5D-5L VAS records the patient's health on a vertical visual analogue scale, ranging from 100 (=the best health you can imagine) to 0 (=the worst health you can imagine). |
