Study Endpoints

Primary Endpoints

Change in suicidal ideations in response to Ketamine
Baseline and 24 hours post infusion

Change in suicidal ideation will be assessed 24 hours post-Ketamine infusion using a Scale for Suicidal Ideation, composed of the first five items of the Beck Suicide Inventory + the Hamilton Depression Rating Scale (HAMD-7) suicidality item. The first five items of the Beck Suicide Inventory are rated on a scale of 0-2, and the suicidality item on the HAMD-7 is rated from 0-4. Scores are totaled and will be analyzed as the dependent variable in a mixed-effects model with drug condition (placebo/perampanel) and time (baseline, 24-hour follow up) as within-subject factors.

Change in antidepressant response to Ketamine
Baseline and 24 hours post infusion

Changes in depressive symptoms will be assessed 24 hours post-Ketamine infusion using the full Hamilton Depression Rating Scale (HAMD-7), a 7-item survey to assess depression. Scores range from 0-26 with scores indicating full remission (0-3) and partial/non-response (4-26). Scores are totaled and will be analyzed as the dependent variable in a mixed-effects model with drug condition (placebo/perampanel) and time (baseline, 24-hour follow up) as within-subject factors.

Treatment Arms

ArmTypeDescription
Perampanel + KetamineEXPERIMENTALParticipants will receive oral perampanel or placebo, in counterbalanced order, 2.5 hours before a standard, subanesthetic Ketamine infusion (0.5 mg/kg over 40 minutes). Ketamine infusions will be at least three weeks apart. Participants will refrain from caffeine and over-the-counter medication seven days before the infusion day.
Placebo + KetaminePLACEBO_COMPARATORParticipants will receive oral perampanel or placebo, in counterbalanced order, 2.5 hours before a standard, subanesthetic Ketamine infusion (0.5 mg/kg over 40 minutes). Ketamine infusions will be at least three weeks apart. Participants will refrain from caffeine and over-the-counter medication seven days before the infusion day.

Frequently asked questions about Perampanel

What is Perampanel used for in Depressive Disorder?

Perampanel is an investigational small molecule being studied for Depressive Disorder, including Major Depressive Disorder, Bipolar Disorder, Post Traumatic Stress Disorder, and Suicidal Ideation. It is currently in Phase 2 clinical development and is not yet approved for this use.

What does Perampanel target?

Perampanel targets the AMPA receptor, a type of glutamate receptor in the brain. By blocking this receptor, it may modulate excitatory neurotransmission, which is being investigated for its potential impact on depressive symptoms and suicidal ideation.

Who makes Perampanel?

Perampanel is being developed by National Healthcare Corp. (ticker: NHC). The company is conducting a Phase 2 clinical trial to evaluate the drug for Depressive Disorder and related conditions.

What phase is Perampanel in?

Perampanel is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities for any use. The current Phase 2 trial is actively recruiting participants.

What clinical trials is Perampanel in?

Perampanel is being studied in a Phase 2 clinical trial with the identifier NCT05786066, titled 'The Impact of AMPA Receptor Blockade on Ketamine's Anti-Suicidal Effects.' This randomized, double-blind, placebo-controlled trial is recruiting 30 participants in the United States.

Is Perampanel the same as Perampanel 6 MG?

Yes, Perampanel 6 MG is another name for Perampanel. The drug is also known by this alternative name, which refers to the 6 milligram dosage form being studied in clinical trials.
