Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Quetiapine

Quetiapine will be cross-tapered up to a maximum dose of 200 mg (as tolerated) as other standard of care medications are discontinued.

Group Type EXPERIMENTAL

Quetiapine Fumarate

Intervention Type DRUG

Quetiapine is an atypical antipsychotic approved by the FDA for the treatment of schizophrenia, bipolar disorder, and as an adjunct to treat major depression. It has a broad spectrum of actions at dopaminergic (D1, D2, D3 and D4), serotonergic (5-HT2A, 5-HT2C and 5-HT7), adrenergic (α1), histaminic (H1) and muscarinic (mACh), and partial agonist at 5-HT1A receptors.

Treatment As Usual (TAU)

Participants in the TAU group will have doses adjusted over the same period as indicated by usual care criteria.

Group Type ACTIVE_COMPARATOR

TAU

Intervention Type DRUG

Standard of care psychotropic medications for treatment of patients with mTBI.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Male or female veterans seeking treatment for mTBI, aged 18-65 years
2. Meet mTBI diagnosis and have PCS symptoms reported on the Neurobehavioral Symptom Inventory (NSI). Six months or more must elapse between the injury and Screening. mTBI diagnosis will be determined using the provisional diagnostic convention recommended by the VA/DoD requiring loss of consciousness, or a period of altered consciousness, or posttraumatic amnesia;
3. Be stable (i.e., no dose changes for \> 1 month) on at least three CNS active psychotropic medications prescribed for symptom relief or psychiatric treatment.
4. Have posttraumatic symptoms measured by PTSD Checklist for DSM-5 (PCL-5) score ≥25.

Exclusion Criteria

1. Moderate or severe TBI, or major neurocognitive disorder (dementia).
2. Meet DSM-5 criteria for schizophrenia, bipolar disorder, schizoaffective disorder, or requiring inpatient hospitalization currently or within past 6 months.
3. Currently taking any antipsychotics or prohibited medication within the past month .
4. Known intolerance to quetiapine or a history of clinically unstable heart, lung, liver, renal, hematological, or endocrinological condition, diabetes mellitus, severe sleep apnea and/or seizure disorder.
5. Substance use disorder severe enough to require medication treatment or medical detoxification or inpatient hospitalization within 6 months of screening.
6. Reporting suicidal ideation of type 4 or 5 in the Columbia Suicide Severity Rating Scale (CSSRS) in the past 3 months prior to screening or at screening or baseline visit (i.e. active suicidal thought with method and intent but without specific plan, or active suicidal thought with method, intent, and plan); or homicidal ideation with intent or plan to harm others within 90 days or suicide attempt; or suicidal behavior within 6 months prior to screening.

(Note: Study psychiatrist will be immediately notified when SI or HI intent is positive)
7. Current or known history of cardiac arrhythmia or QTc interval ≥ 470 milliseconds.
8. Pregnant or lactating women and those of child-bearing potential not using a reliable method of contraception will be excluded from participating in the study.
