Description Research Excerpts Clinical Trials Roles Classes Pathways Study Profile Bioassays Related Drugs Related Conditions Protein Interactions Research Growth Market Indicators

Lamotrigine is an anticonvulsant medication used to treat epilepsy, bipolar disorder, and nerve pain. It was first synthesized in 1980 by scientists at Wellcome Laboratories. Lamotrigine works by reducing the release of glutamate, an excitatory neurotransmitter, in the brain. This helps to prevent seizures and reduce the symptoms of bipolar disorder. Lamotrigine is generally well-tolerated, but side effects can include dizziness, headache, and skin rash. It is important to note that lamotrigine can interact with other medications, so it is important to talk to your doctor about all the medications you are taking before starting lamotrigine. Lamotrigine is a widely studied drug due to its effectiveness in treating epilepsy and bipolar disorder. Research is ongoing to investigate the potential benefits of lamotrigine for other conditions, such as migraines and chronic pain. '

Effects

Lamotrigine (LTG) has a broad spectrum of antiepileptic efficacy and generally benign side effects except for idiosyncratic rashes. It has a modulating effect on glutamatergic neurotransmission relevant to pathophysiology of both schizophrenia and OCD.

Lamotrigine has a favorable pharmacokinetic profile, including a long half-life, low serum protein binding, and lack of mixed-function oxidase enzyme induction. It has not been associated with an increased risk for major malformations in monotherapy in most available studies.

Bioavailability

Lamotrigine should be taken preferably in fasting condition, as presence of food (low fat, low calorie or high fat, high calorie) decreases the bioavailability to a significant extent.

Mean Change From Baseline in the Epworth Sleepiness Scale (ESS) 8-Item Total Score at Week 19 of the Double-Blind Treatment Phase

The ESS is an 8-item, self-administered questionnaire that measures excessive daytime sleepiness in adults. The instrument captures information on the extent to which the participant would be likely, or not, to fall asleep in certain situations. The stimulus question is: How likely are you to doze off or fall asleep in the following situations, in contrast to feeling just tired? Questions are answered on a 4-point scale (would never doze [0] to high chance of dozing [3]). The total score ranges from 0 to 24, where a higher score indicates a higher chance of dozing.

Mean Change From Baseline in the Adverse Experience Profile (AEP) Total Score at Week 19 of the Double-Blind Treatment Phase

The AEP is a list of 19 items covering many possible side effects attributable to drug treatment. The participants respond by assessing how much each event has been a problem for them over the past 4 weeks (1=Never a Problem to 4=Always a Problem). Each individual item can be examined; an overall adverse events score is calculated as the sum of the scores across the 19 items. The AEP total score ranges from 19 to 76, with a higher score indicating a higher degree of adverse event severity. (NCT00104416)

Mean Change From Baseline in the Center for Epidemiological Studies-Depression Scale (CES-D) Total Score at Week 19 of the Double-Blind Treatment Phase

The 20-item CES-D questionnaire is self-administered and asks respondents to report the frequency to which the 20 events were experienced over the past week. A 4-point Likert scale is used and ranges from rarely or none of the time (0) to most or all of the time (3). The total score, a sum across the 20 items (ranging from 0 to 60), determines the extent to which a participant may be experiencing depression. Higher scores indicate a higher severity of depression.

Mean Change From Baseline in the Neurological Disorders Depression Inventory-Epilepsy (NDDI-E) 6-Item Total Score at Week 19 of the Double-Blind Treatment Phase

The NDDI-E is a self-reported questionnaire composed of 46 brief phrases/words to identify mood disorders across the spectrum of depression. It was developed to capture depressive moods that are co-morbid with the disease of epilepsy or its treatment as well as to measure the depressive state of the participant. All phrases are measured on a 4-point Likert scale of Never (1) to Always/often (4) and refer to the participants' mood over the past week. Scoring is comprised of a total mood score calculated by summing the scores of 6 specific items (from 6=never to 24=always or often). (NCT00104416)

Young Mania Rating Scale (YMRS),

This measure has 11 items. The purpose of each item is to rate the severity of that abnormality in the patient. A severity rating is assigned to each of the eleven items, based on the patient's subjective report of his or her condition over the previous forty-eight hours and the clinician's behavioral observations during the interview, with the emphasis on the latter. There are four items that are graded on a 0 to 8 scale (irritability, speech, thought content, and disruptive/aggressive behavior), while the remaining seven items are graded on a 0 to 4 scale. Total score of zero to 60 is possible, zero being normal and 60 being severe, 12 serving as a cut off point for illness if equal or above. There are several ways to show change in outcome. The mean and standard deviation at week 0, 8 and 14 will indicate if there is a change in the scores with the treatment. (NCT00176228)

Rey Auditory Verbal Learning Test (RAVLT)

Rey Auditory Verbal Learning Test (RAVLT) is a test of verbal learning and declarative memory. During the test, 15 nouns that are read aloud for 5 consecutive trials. Each trial is followed by a free recall test (participant is asked to recall the words that were just read to them). The sum of correctly recalled words across 5 trials is called the total raw score. On completion of Trial 5, an interference list of 15 words (List B) is presented, followed by a free recall test of that list. After a 20-min delay, the examinee is again required to recall the words from list A - this is called the delay raw score. The raw scores on both the total recall and the delay trials (number of words correct across trials 1-5) are converted to standardized T-scores (Mean=50; SD=10; range 20-100) based on participant age and gender. The scores below are presented as T-scores, with higher scores indicative of better performance. (NCT00223262)

Percent Change From Baseline (BL) in Weekly Seizure (sz.) Frequency for All Partial Seizures During Each Phase of the Study

Partial-onset sz. have a focal site of onset; sz. activity is initially limited to 1 brain hemisphere. Partial sz. can remain simple or complex, or evolve to generalized tonic-clonic sz. Participants (par.) recorded the number of sz., by type as well as the episode duration of innumerable sz. activity), in daily diaries. If par. withdrew from study, data were averaged for the study portion the par. completed up to the time of drug discontinuation. Percent change from BL = (BL value minus study phase value divided by BL value) x 100; positive values indicate reduction from BL in sz. frequency. (NCT00516139)

Psychotic Symptoms

Psychotic symptoms were assessed and scored using the Structured Interview for the Prodromal Syndrome (SIPS) and the Scale of Prodromal Symptoms (SOPS). The SOPS provides a measure of four domains of symptoms, including positive, negative, disorganized and general symptoms. The Positive Symptom sub-scale score reported is the sum of all five symptom items in the Positive Symptom sub-scale. The Positive Symptom sub-scale assesses psychotic symptoms, each item on a scale of 0-6. The sum scale score is 0-30, with 30 indicating severe psychotic symptoms, while 0 indicates no psychotic symptoms. (NCT00531518)

Young Mania Rating Scale (YMRS) Total Score at Weeks 6, 16, 28, 40, and 52/EW

"The YMRS is an 11-item, multiple-choice diagnostic questionnaire used to measure the severity of disease in participants. Individual items (1=elevated mood, 2=increased motor activity, 3=sexual interest, 4=sleep, 5=irritability, 6=speech, 7=language thought disorder, 8=content, 9=disruptive aggressive behaviour, 10=appearance, 11=insight) were rated on a scale of 0-4 and 0-8. For all items, 0 is the best rating and 4 or 8 is the worst rating. YMRS total score was computed as the sum of the scores for the 11 items on the scale. The possible total scores range from 0 (best) to 60 (worst)." (NCT00566020)

Number of Participants With Any Serious Adverse Event (SAE) and Any Non Serious Adverse Event

An adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of medicinal product, which does not necessarily have a causal relationship with the treatment. An SAE is any untoward medical occurrence that, at any dose, results in death, is life-threatening, requires inpatient hospitalization or causes its prolongation, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event. A complete list of all SAEs and AEs experienced in the study can be found in the SAE/AE section. (NCT00566020)

N-acetylaspartic Acid (NAA) Measured in the MACC and LDLPC Using the Long TE (TE80) PRESS MRS Technique at Baseline for Both Groups, and After 12 Weeks of Lamotrigine Monotherapy for the Bipolar (BP) Group and BP Responders and Non-responders

Two different MRS sequences were used to measure the brain chemicals in a single 2 x 2 x 2 cm cube located in the center of anterior cingulate cortex: an intermediate echo-time PRESS sequence and a 2D J-resolved averaged PRESS sequence. (Note: The intermediate echo-time PRESS sequence was used for this outcome measure.) Spectroscopic data were inspected for quality; subjects whose data were contaminated by artifact were excluded from the study. Spectra were then processed using LCModel to quantify brain chemical levels. Regular brain MRI images were segmented, yielding a map of the amount of CSF in the head. The MRS voxel was overlaid onto the CSF map and the fraction of CSF within the voxel measured. This CSF-corrected measurement was used for statistical analysis. (NCT01042496)

Glutamate+Glutamine (GLX) Measured in Mid Anterior Cingulate Cortex (MACC) & Left Dorsal Lateral Prefrontal Cortex (LDLPC) Using Long TE PRESS MRS Technique at Baseline for Both Groups; After 12 Weeks of Lamotrigine Monotherapy for the Bipolar Group

Two different MRS sequences were used to measure the brain chemicals in in anterior cingulate and left dorsal lateral prefrontal cortex : an intermediate echo-time PRESS sequence and a 2D J-resolved averaged PRESS sequence. (Note: The intermediate echo-time PRESS sequence was used for this outcome measure.) Spectroscopic data were inspected for quality; subjects whose data were contaminated by artifact were excluded from the study. Spectra were then processed using LCModel to quantify brain chemical levels. Regular brain MRI images were segmented, yielding a map of the amount of cerebrospinal fluid (CSF); the MRS voxel was overlaid onto the CSF map and the fraction of CSF was measured. This CSF corrected measurement was used for statistical analysis. (NCT01042496)

The Rey Auditory Verbal Learning Test (RAVLT)

The Rey Auditory Verbal Learning Test (RAVLT) measures verbal or declarative learning and memory. The test consists of 15 nouns read aloud for five consecutive trials with each trial followed by a free-recall trial. Following the fifth trial, an interference list of 15 different words is presented followed by a free-recall trial of that list. Delayed recall of the first list is tested immediately following the interference list and after a 20-minute delay. A recognition test of 50 words including the 15 original words is presented after the delayed recall. Equivalent, alternative versions (different words) were used to minimize practice or learning effects from repeated administration. The raw scores (number of words correct across trials 1-5) are converted to standardized T-scores (M=50; SD=10). This score is used to determine the participant's performance in relation to norm-referenced expectations based on age and sex. A higher score reflects better performance. (NCT01142310)

Time to Withdrawal/Dropout From the Study (Across Seizure Types and by Seizure Type in Past 6 Months in the Escalation and Maintenance Phases)

Time to withdrawal is defined as the time from the start of treatment until withdrawal from the study. Seizure types are defined as: ALL=any type of seizure; A: simple partial seizures, B: complex partial seizures; C: partial seizures evolving to secondary generation seizures; D5: tonic-clonic seizures. Simple partial seizures are seizures which affect only a small region of the brain, often the temporal lobes or hippocampi. Simple partial seizures are seizures that affect only a small region of the brain, often the temporal lobes or hippocampi. Complex partial seizures are epileptic seizures that are associated with bilateral cerebral hemisphere involvement and cause impairment of awareness or responsiveness. Partial seizures evolving to secondary generation seizures are seizures that start as partial seizures, then spread to include the entire brain. Tonic-clonic seizures are a type of generalized seizure that affects the entire brain. (NCT01431963)

Child Behavior Checklist

The Child Behavior Checklist is a measure of specific behavioral and emotional problems are rated by the child's parent or guardian. The Child Behavior Checklist examines three domains (Social Functioning, Mood and Anxiety Symptoms, and Externalizing Symptoms) by assessing 118 problem items that describe specific behavioral and emotional problems. Respondents indicate how accurately the statements describe the child by selecting from options on a 3-point Likert-type scale (0=Not True, 1= Somewhat or Sometimes True, or 2=Very True or Often True). Total raw scores are converted to t-scores with a mean of 50 and standard deviation of 10. A t-score of 67 or greater is considered to be in the clinical range for problematic behavior. (NCT01891890)

Wechsler Intelligence Scale for Children-IV Processing Speed

Coding and Symbol Search subtests from the Wechsler Intelligence Scale for Children (WISC)-IV are measures of processing speed and combine to form the Processing Speed Index. Processing speed refers to how quickly the child understands and responds to information. Coding presents children with a row of boxes containing a numeral in the top line and a symbol in the bottom line with the task of copying the symbol corresponding to each numeral as quickly as possible in 120 seconds. In Symbol Search, children are given rows of symbols and target symbols and are asked to mark whether or not the target symbols appear in each row as quickly as possible during 120 seconds. Composite scores compare the test-taker to peers with a mean score of 100 and a standard deviation of 15. Possible scores range from 40 to 160 with higher scores indicating increased processing speeds. Scores between 85 and 115 are considered average, with 2/3 of test takers falling between these values.

"Story Memory will be measured at baseline with the Children's Memory Scale (CMS) and then with the Wide Range Assessment of Memory and Learning-2 (WRAML-2) at the 6 month follow up visit. Two different tests are used to avoid practice effects in memory assessment associated with repeated assessments using the same stimulus material. The Story Memory sub-test of the CMS and the WRAML-2 Story Memory are measures of prose passage recall. Stories are read to the subject for recall, with different stories presented based upon participant age. Scores are converted to percentile ranks for both measurements of story memory. Possible scores can fall between the 1st and 99th percentile and higher values indicate better performance with story recall. Values between the 9th and 25 percentiles are considered low average, values between the 25th and 75th percentiles are average, while values between the 75th and 91st percentile are high average."

Pediatric Neuro-QOL Score

The Pediatric Neuro-QOL is a Quality of Life instrument developed in conjunction with NIH with a pediatric specific form utilized in this protocol. Pediatric Neuro-QOL assesses the domains of Anger, Anxiety, Cognition, Depression, Fatigue, Pain, Social Relations, and Stigma. Each domain has 8 to 10 items and respondents indicate how often they experienced feelings and circumstances related to each domain on a scale of 1 to 5 (such as 1=never, 2=almost never, 3=sometimes, 4=often, 5=almost always). Higher values indicate increased difficulty for most of the scales but this pattern is reversed for two of the domains. Raw scores are rescaled to standardized scores with a mean of 50 and a standard deviation of 10. Higher values for the standardized scores indicate more problematic characteristics while scores below 50 indicate that the child is experiencing less trouble in the domains measured by the Pediatric Neuro-QOL.

Percentage of Participants With at Least One Adverse Event (AE) During the Study

An AE was any untoward medical occurrence in a patient or clinical investigation study participant administered a pharmaceutical product that did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Number of Patients With Psychologic Disturbances-

The psychologic side-effects were measured in PACU (up to 90 minutes after ketamine infusion). This included four key items of the Brief Psychiatric Rating Scale (BPRS) corresponding to positive symptoms of schizophrenia: conceptual disorganization, hallucinatory behavior, suspiciousness, and unusual thought content. Each symptom is rated 1-7 ( 1 = not present, 2 = very mild, 3 = mild, 4 = moderate, 5 = moderately severe, 6 = severe, 7 = extremely severe ), and, therefore, the total score as the primary outcome based on four key items of BPRS will be between 4 (best score) and 28 (worst score). Patients who had a total score of 4 (all symptoms not present) were determined as not having psychologic disturbance and patients who had a total score of > 4 (having any symptoms present) were determined as having psychologic disturbance. (NCT03831854)
Timeframe: Up to 90 minutes of PACU arrival
