About this study

Official title: Medication and Psychotherapy Treatment Trial for Psychogenic Nonepileptic Seizures

The investigators propose that patients who receive targeted pharmacotherapy (sertraline) or focused psychotherapy (cognitive behavioral therapy-informed psychotherapy (CBT-ip) for NES) or combined treatment (CBT-ip + sertraline) will report fewer nonepileptic seizures (NES) compared to patients who receive community care / treatment as usual (TAU). The purpose of this study is to provide pilot testing and data to inform the future multicenter randomized controlled trial based on the hypothesis.

Read the detailed description

This is a pilot, prospective, multi-center, randomized controlled trial, that assesses the number of NES in patients treated with either flexible dose sertraline (Zoloft), cognitive behavioral therapy-informed psychotherapy (CBT-ip), combined therapy (sertraline + CBT-ip) or community care (treatment as usual TAU). This study will provide outcomes data and the effect size necessary for a future R01, multi-center randomized control trial. Secondary objective variables include reduction in depression, anxiety, impulsivity scores, and improvement in psychosocial functioning.

After being diagnosed with NES by video EEG monitoring (vEEG), up to 40 participants will be enrolled and monitored during a two week lead in period for their baseline NES and psychosocial symptoms and functioning. At week 2, they will be randomized to either: flexible dose sertraline (25 to 200mg), CBT, CBT+med, or to the control arm, TAU. Participants randomized to the sertraline arm will be titrated over 6 weeks up to 200mg or to dose limited by side effects. The subjects will stay on their maximum fixed dose for the next 4 weeks. At week 10, the subjects may elect to remain on the sertraline or they can taper off the medication over the final two weeks of the treatment trial. Those randomized to the CBT-ip arm will receive 12 weekly sessions of CBT-ip for NES. Those randomized to the CBT-ip + med arm will receive both treatments. Those randomized to the TAU arm will follow with their treatment providers.

After the treatment trial, the subjects will have follow up phone calls at month 4, 8, and 12 after enrollment to assess seizure status, medication usage, and global functioning.

Upon enrollment, subjects will be evaluated with a structured psychiatric and neurological exam, and with bi-weekly, 30 to 60 minute appointments where they will complete symptom and function scales. They will keep a seizure diary to evaluate their daily seizure activity.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing sertraline, CBT-ip and Combined (sertraline + CBT-ip) in people with Convulsion, Non-Epileptic and Conversion Disorder, run by Rhode Island Hospital at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

seizure frequency (time frame: weekly). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00835627, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Nov 2014.
