The purpose of this study is to assess the safety and tolerability of intravenous (IV)
carbamazepine (CBZ) administered as multiple 15 minute infusions to adult patients with
epilepsy on stable higher doses of oral CBZ.
Official title: Open-Label Study to Assess the Safety and Tolerability of Intravenous Carbamazepine as Short-Term Replacement of Oral Carbamazepine in Adult Patients With Epilepsy
Study design: Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: The primary objective to assess the safety and tolerability of IV CBZ administered as multiple 15 minute infusions to adult patients with epilepsy on stable higher doses of oral CBZ includes adverse events, laboratory test results, and ECG parameters
Secondary outcome: For the secondary objective to assess biomarkers for renal effect of IV CBZ, the variables of interest include the analytes collected in the 24-hour urine collection relative to the creatinine volume excreted
This is a phase III, multicenter, open-label study designed to assess the safety and
tolerability of intravenously administered CBZ in adult patients with epilepsy. This study
will include a 28 day Lead-in Period, a Confinement Period (up to 7 days and 6 nights) and a
28 day Follow-up Period.
Patients will begin confinement on Day - 1 of the trial, continuing to take their oral CBZ as
prescribed by the investigator. On the morning of Day 0, Day 4, and Day 17, patients will
begin the 24hr urine collection for evaluation of urinary biomarkers. All patients will
temporarily discontinue their prescribed oral CBZ and begin IV CBZ administration on the
morning of Day 1, continuing administrations every 6 hours (Q6h) through the morning of Day
Minimum age: 18 Years.
Maximum age: N/A.
1. The patient or legal representative must be able to read, understand, sign and date
the IRB approved Informed Consent Form and HIPAA Authorization prior to study
2. The patient is a man or a non-pregnant woman who is at least 18 years of age.
3. If a woman:
- Patient is either not of childbearing potential, defined as postmenopausal for
at least 1 year or surgically sterile (bilateral tubal ligation, bilateral
oophorectomay or hysterectomy), or if childbearing potential, must comply with a
method of birth control acceptable to the investigator during the study, for at
least 28 days prior to Day 1 and for 28 days following completion of the study.
- Patient is not breastfeeding.
- Patient of childbearing potential must have a negative serum pregnancy test at
Day - 28 and a negative urine pregnancy test or serum pregnancy test at Day -1.
4. The patient is diagnosed with any of the approved epilepsy indications for CBZ:
- Partial seizures with complex symptomatology (psychomotor, temporal lobe)
- Generalised tonic clonic seizures (GTCS) (grand mal): myoclonic, clonic, tonic,
- Mixed seizure patterns that include the above, or other partial or generalised
seizures (except absence seizures - please see exclusion point number 12)
5. The patient is receiving a stable dose of oral CBZ (tablet or capsule formulation) of
1200 mg/day to 2000 mg/day, for a minimum of 14 days prior to Day - 28.
6. The patient is receiving a constant dose of all other concomitant medications used
for chronic conditions, (including OTC medications and herbal supplements) for a
minimum of 28 days prior to Day 1.
7. The patient is not expected to have any change in his/her baseline AED treatment
during the treatment period.
8. The patient is able to comply with maintaining an accurate Seizure and antiepileptic
9. The patient is able to comply with all study procedures including complying with
protocol determined dosing intervals, confinement at the investigative site for up to
6 nights and 7 days, and agrees to participate in the entire study.
1. The patient has a known hypersensitivity to CBZ, Captisol, or to any of the tricyclic
compounds, such as amitriptyline, trimipramine, imipramine; oxacarbazepine,
phenytoin, or their analogues or metabolites.
2. The patient has a history of previous bone marrow depression.
3. The patient has a history of intolerance to IV administration of medication.
4. The patient is pregnant or lactating.
5. The patient is being treated with a monoamine oxidase (MAO) inhibitor.
6. The patient is using oral, intramuscular, or any other hormone delivery method as
their primary form of birth control.
7. The patient has an ECG with corrected QT interval by Fridericia's correction formula
(QTcF) greater than 450 msec at Screening or Day - 1.
8. The patient has a screening ALT, AST or bilirubin >=3 times the upper limit of
9. The patient has an estimated ClCR (based of Cockcroft-Gault) of <50 ml/min.
10. The patient has had a clinically significant illness/infection or has had any
surgical procedure within 30 days prior to Screening.
11. The patient has a significant history of cardiac, renal, neurologic (other than
epilepsy), psychiatric, oncologic, endocrinologic, metabolic, or hepatic disease,
which would adversely affect their participation in this study.
12. The patient is receiving oral CBZ for absence seizures.
13. The patient has had an episode of status epilepticus within 4 weeks of Screening.
14. The patient has a history of severe or serious adverse reactions to CBZ (for example,
aplastic anemia, agranulocytosis, SJS.
15. The patient has taken or used any investigational drug or device in the 30 days prior
16. The patient has previously been administered IV CBZ in a previous clinical trial (for
17. The patient has a urine toxicology screen positive for phencyclidine, benzodiazepines
(unless due to the patient's concomitant AEDs), cannabinoids, cocaine, amphetamines,
opiates, barbiturates (unless due to the patient's concomitant AEDs), or alcohol at
Screening or Day - 1.
18. The patient has had a diagnosis of drug or alcohol abuse within the past year prior

22. The patient has a history of increased intraocular pressure or is on medication for
23. The patient is considered by the investigator to be an unsuitable candidate for the
study, which may include an increase in the frequency, severity and duration of
seizures during the Pre-Treatment Period (Days - 28-0).
24. The patient has previously participated in this study.
25. The patient is a member of the site personnel or their immediate families.
