Inpatient, Dose-Ranging Study of Staccato Alprazolam in Epilepsy With Predictable Seizure Pattern

Completed · Phase 2 · Has a placebo group

Conditions studied: Epilepsy

In brief

This is a multi-center, double-blind, randomized, parallel group, dose-ranging study to investigate the efficacy and clinical usability of STAP-001 in adult (18 years of age and older) subjects with epilepsy with a predictable seizure pattern. These subjects have an established diagnosis of focal or generalized epilepsy with a documented history of predictable seizure episodes. This is an in-patient study. The subjects will be admitted to a Clinical Research Unit (CRU) or Epilepsy Monitoring Unit (EMU) for study participation. The duration of the stay in the in-patient unit will be 2-8 days. One seizure event per subject will be treated with study medication. The duration and timing of the seizure event and occurrence of subsequent seizures will be assessed by the Staff Caregiver(s)1 through clinical observation and confirmed with video electroencephalogram (EEG).

You may qualify if…

• Subject is able to provide, personally signed, and dated informed consent to participate in the study or will have a legally authorized representative sign the informed consent on his or her behalf before completing any study related procedures.
• Male or female ≥ 18 years of age.
• Has an established diagnosis of focal or generalized epilepsy or focal and generalized epilepsy with a documented history of predictable seizure episodes that includes at least one of the following:
• Generalized seizure episodes starting with a flurry of absence seizures or myoclonic seizures with a minimum duration of 5 minutes
• Episodes of a prolonged focal seizure with a minimum duration of 3 minutes
• Episodes of multiple (≥2) seizures within a 2-hour time period
• Prior to randomization, has experienced ≥4 seizure episodes with predictable pattern during the last 4 weeks (qualification period) and no more than one week without a predictable seizure episode before entry into the in-patient unit.
• Female participants (if of child-bearing potential and sexually active) and male participants (if sexually active with a partner of child-bearing potential) who agree to use a medically acceptable and effective birth control method throughout the study and for 1 week following the end of the study. Medically acceptable methods of contraception that may be used by the participant and/or his/her partner include abstinence, birth control pills or patches, diaphragm with spermicide,intrauterine device (IUD), surgical sterilization, and progestin implant or injection. Prohibited methods include: the rhythm method, withdrawal, condoms alone, or diaphragm alone.
• Subject is able to comply by the requirements of the protocol, particularly the requirements and specific Institution policies during the in-clinic stay.

You may not qualify if…

• History or diagnosis of non-epileptic seizures (e.g. metabolic or pseudo-seizures).
• History of status epilepticus in the 6 months prior to Screening
• Has a progressive neurological disorder such as brain tumor, demyelinating disease, or degenerative central nervous system (CNS) disease that is likely to progress in the next 3 months
• Use of strong CYP 3A4 inhibitors; including azole antifungal agents (e.g., etoconazole, itraconazole), nefazodone, fluvoxamine, cimetidine, HIV protease inhibitors (e.g., ritonavir)
• Has severe chronic cardio-respiratory disease
• History of HIV-positivity.
• Pregnant or breast-feeding.
• Clinically significant renal or hepatic insufficiency (hepatic transaminases >2 times the upper limit of normal (ULN) or creatinine ≥ 1.5 x ULN).
• History of acute narrow angle glaucoma, Parkinson's disease, hydrocephalus, or history of significant head trauma.
• Subjects who use medications to treat airways disease, such as asthma or COPD or have any acute respiratory signs/symptoms (e.g., wheezing).
• Use of any investigational drug within 30 days or 5 half-lives of the investigational drug prior to administration of study medication, whichever is longer
• A history within the past 1 year of drug or alcohol dependence or abuse.
• Positive urine screen for drugs of abuse at Screening.(positive Cannabis/Cannabinol results are acceptable if there is a documented history of stable use for medical purposes).
• Known allergy or hypersensitivity to alprazolam.
• History of glaucoma.
• Subjects who currently have an active major psychiatric disorder where changes in pharmacotherapy are needed or anticipated during the study.
• Hypotension (systolic blood pressure ≤90 mm Hg, diastolic blood pressure ≤50 mm Hg), or hypertension (systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥100 mm Hg) measured while seated at screening or baseline.
• Significant hepatic, renal, gastroenterologic, cardiovascular (including ischemic heart disease and congestive heart failure), endocrine, neurologic or hematologic disease.
• Subjects who, in the opinion of the Investigator, should not participate in the study for any reason, including if there is a question about the stability or capability of the subject to comply with the trial requirements.
