What clinical trials were run for Seroquel (quetiapine)?
Seroquel (quetiapine) is an antipsychotic drug that has been studied in multiple clinical trial programs across different conditions, including schizophrenia, bipolar disorder, and major depressive disorder (MDD) as an add-on or combination therapy. The trials typically assessed outcomes such as symptom change on standardized rating scales, time to relapse, and safety/tolerability across short-term and longer-term studies.
Because “Seroquel clinical trials” can refer to different disease areas and time periods, the most useful way to find the exact studies is by indication (schizophrenia vs. bipolar vs. bipolar depression vs. MDD) and whether you mean efficacy trials or relapse-prevention/safety trials.
Which conditions have Seroquel clinical trials for?
Searchers often mean one of these indication clusters:
- Schizophrenia (symptom reduction and maintenance/relapse prevention)
- Bipolar disorder (acute mania/mixed episodes and maintenance)
- Bipolar depression (quetiapine monotherapy studies)
- Major depressive disorder (quetiapine as an add-on in clinical trial programs)
If you tell me which condition you care about, I can narrow to the specific trial types and common endpoints used for that indication.
How can I find the exact Seroquel study names, results, and dates?
Clinical trial identifiers and primary results are typically published in:
- ClinicalTrials.gov entries (by drug and condition)
- Peer-reviewed journal articles (often tied to FDA labeling and meta-analyses)
- Regulatory documents that compile trial evidence by indication
To make this concrete, tell me whether you want:
- trial registry listings (ClinicalTrials.gov-style),
- published papers (journal studies),
- or FDA-label “study summaries” by indication.
Are there trials comparing Seroquel to other antipsychotics?
Comparative trials do exist across antipsychotic classes, but which ones apply to “Seroquel” depends on the specific indication and comparator drug. In practice, many pivotal programs for Seroquel were designed around placebo or standardized rating-scale improvements, and later evidence may include head-to-head studies or comparative effectiveness analyses.
What safety outcomes do Seroquel trials track?
Across Seroquel studies, safety monitoring commonly covers:
- adverse events and treatment discontinuation
- sedation/somnolence and related tolerability
- metabolic signals (weight gain, lipids, glucose markers) as part of the safety profile
- cardiovascular measures and other class-relevant monitoring
If your goal is patient-focused (for example, “What side effects were most common in trials?”), say so and I’ll focus on the trial-reported adverse events rather than trial design.
Does Seroquel have special trial requirements (pediatrics, elderly, or misuse concerns)?
Seroquel’s trial evidence and labeling differ by age group and indication, and clinical studies often include subgroup analyses and safety monitoring for populations like adolescents vs adults. Whether something like pediatric trials apply depends on which formulation and indication you mean.
If you specify the patient group (adult vs adolescent) and condition, the trial set you need will change.

Quick question to narrow it down
Which Seroquel clinical trials are you looking for: schizophrenia, bipolar disorder, bipolar depression, or major depressive disorder (add-on)? Also, do you want trial registry entries (ClinicalTrials.gov) or published study results?
