Background:
- The brain chemical serotonin helps nerve cells communicate. Previous research suggests that serotonin activity may be lower in brain areas where seizures start, and that increasing activity at the serotonin receptor site on nerve cells may help prevent seizures. Researchers are interested in determining whether the experimental medication PRX-00023, which increases the activity of serotonin receptors, can reduce seizure frequency in people whose seizures are not well-controlled on antiseizure medication. PRX-00023 has not previously been studied in people with epilepsy and has not previously been given to people taking antiseizure medication at the same time.
Objectives:
- To evaluate the effectiveness of PRX-00023 in reducing the frequency of epileptic seizures that start from only one part of the brain.
Eligibility:
- Individuals between 18 and 65 years of age who have frequent epileptic seizures even after trying at least two different standard anti-seizure medications (either at the same time or one after the other).
Design:
Outcome measures:
The primary outcome measure for drug efficacy will be:
Mean difference in seizure frequency comparing the active and placebo periods.
Secondary outcome measures for efficacy will be:
Proportion of patients with greater than or equal to 50% lower seizure rate on PRX-00023 than placebo
Hamilton Depression and Anxiety Rating scales
Performance on mood and neuropsychological testing scales
Introduction:
PRX-00023 is a selective 5HT1A agonist being developed as an oral therapeutic treatment for epilepsy.
Objective:
To initiate a pilot clinical trial assessing the safety, tolerability and efficacy of the 5HT1A receptor agonist PRX-00023 in patients with localization-related epilepsy. PRX-00023 is a 5HT1A receptor agonist that has shown promise in clinical trials of depression. Patients with localization-related epilepsy have reduced 5HT1A receptor binding on 18FCWAY positron emission tomography (PET). Increasing neurotransmitter activity at 5HT1A receptor sites might ameliorate seizures. Moreover, depression is a common co-morbidity in people with epilepsy. Altered 5HT1A receptor binding has been found in depression.
Study Population:
Thirty adults with localization-related epilepsy.
Design:
A randomized, double-blind, placebo-controlled cross-over, phase II clinical trial. Subjects will be screened under protocol 01-N-0139 and will undergo medical and epilepsy history and physical examination, vital signs, ECG, clinical laboratory studies including standard clinical chemistry and hematology studies, urinalysis, pregnancy test for females of childbearing potential, and MRI scan and eo EEG monitoring will be performed if not previously completed successfully, and measurement of plasma AED levels (for those AEDs in which an assay is available at NIH).
The trial will have a baseline phase, which will last up to 6 weeks. Baseline may occur concurrent with screening procedures. The baseline phase will include measurement of seizure frequency (patient will record via seizure calendar). In addition the following will be administered, unless previously completed: Columbia Suicide Severity Rating Scale, neuropsychological and mood evaluations, FCWAY PET (if not already performed), EEG, measurement of plasma AED levels (if assay available), and pregnancy test (for women of child bearing potential), saliva samples will be obtained for genetic testing (if not previously obtained) and blood samples will be obtained during the PET procedure for cortisol and ACTH levels.
Following baseline, patients will begin the treatment phase (consisting of Period 1 and Period 2). Patients will be randomized to PRX-00023 (120mg BID) or matching placebo. After completion of the first treatment period, patients will undergo a washout period after which patients will be crossed over to the alternate treatment period.

| Mean Score on the Hamilton Anxiety Rating Scale at the End of the Active and Placebo Periods. | Participants were administered the Hamilton Anxiety Rating Scale (HAM-A) at the end of each three month treatment period, i.e., while participants were either on PRX-0023 or Placebo. The HAM-A measures an individual's severity of anxiety symptoms. The scale consists of 14 parameters, each defined by a series of symptoms. Each group of symptoms is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where </=17 indicates mild anxiety, 18-24 mild to moderate anxiety and 25-30 moderate to severe anxiety and >30 severe anxiety. | Three months |
| Mean Score on the Hamilton Depression Rating Scale at the End of the Active and Placebo Periods | The Hamilton Depression Rating Scale (HAM-D) was administered to participants at the end of each treatment period. The HAM-D is a multiple item questionnaire used to provide an indication of depression. The questionnaire is designed for adults and is used to rate the severity of their depression by probing mood, feelings of guilt, suicide ideation, insomnia, agitation or retardation, anxiety, weight loss, and somatic symptoms. Although the HAM-D form lists 21 items, the scoring is based on the first 17 items. Eight items are scored on a 5-point scale, ranging from 0 = not present to 4 = severe. Nine items are scored from 0-2 with 0 = absent and 2 = frequent or severe. Scores range from 0 to 50 with a score of 0-7 representing normal and a score >/= 23 representing very severe depression. | Three months |
| Mean Score on the Hopkins Verbal Learning Test-Revised (HVLT-R) at the End of the Active and Placebo Periods | The HVLT-R is a word-list learning and memory test.The participant is read a list of words and asked to recall as many as possible, without regard to the order in which they were read.The list is read three times with recall requested after each presentation (immediate recall) and after a delay (delayed recall). Individual test results are compared to others of the same age (+/-5 years).Test results are presented as T-scores which are conventionally used in neuropsychology. The participant's raw scores are compared to a population expected raw score, for a particular age group. That score is converted to a T-score.The interpretation of these T-scores is such that 50 is representative of the normal score in that age group in the general population. The standard deviation of these distributions are 10 units. Therefore, a score between 30-40 is considered mildly impaired, 20-30 is indicative of severe problems with learning and memory and a score of 60-70 indicates a very good memory. | Three months |
| The Mean Score on the Brief Visuospatial Memory Test-Revised (BVMT-R), at the End of the Active and Placebo Period. | The BVMT-R is a test of memory for visual information. Participants are shown a page with several geometric designs arranged in a 2x3 matrix and asked to study the designs. After the page is shown for a brief period the participant is asked to draw each figure.The same page is shown three times with recall requested after each presentation (immediate recall) and after a delay (delayed recall). Individual test results are compared to other people the same age (+/- 5 years).Test results are presented as T-scores which are conventionally used in neuropsychology. The participant's raw scores are compared to a population expected raw score, for a particular age group.That score is converted to a T-score.The interpretation of these T-scores is such that 50 is representative of the normal score in that age group in the general population.The standard deviation of these distributions are 10 units. A score of 30-40 is considered mildly impaired, 20-30 is indicative of severe problems | Three months |
| Mean Score on the Columbia Suicide Severity Rating Scale at the End of the Active and Placebo Periods | The Columbia Suicide Severity Rating Scale (C-SSRS) was administered to subjects at the end of each treatment period. The C-SSRS, is a suicidal ideation and behavior rating scale which evaluates suicide risk. The assessment rates an individual's degree of suicidal ideation on a scale, ranging from 0 to 6 as follows: 0 = No suicide ideation; 1 = Wish to be dead; 2 = Non-Specific Active Suicidal Thoughts; 3 = Active Suicidal Ideation with any methods (No Plan) without intent to act; 4 = Active Suicidal Ideation with some intent to act, without specific plan; 5 = Active Suicidal Ideation with specific plan and intent; and 6 = Actual Suicide Attempt | Three months |
| Results of Clinical Examination of the Nervous System at the End of the Active and Placebo Treatment Periods | A clinical examination of the nervous system was administered by a physician to subjects at the end of each three month treatment period, i.e., while the participant was on PRX-0023 or Placebo. Results of the examination ranged from 0-4 with scores defined as follows: 0 = normal examination; 1 = Observation only; patient asymptomatic; 2 = Patient reports complaint associated with finding but no dysfunction; 3 = Patient reports some impairment of daily function associated with finding; 4 = Patient unable to carry out usual activities due to dysfunction associated with finding. | Three months |
| Results of Clinical Examination of the Respiratory System at the End of the Active and Placebo Treatment Periods | A clinical examination of the respiratory system was administered by a physician to subjects at the end of each three month treatment period, i.e., while the participant was on PRX-0023 or Placebo.
