Details and patient eligibility

About

NRL-4, a nasal spray formulation of the atypical antipsychotic olanzapine is being developed by Neurelis Inc. for use as a rescue medication for acute episodes of agitation in schizophrenia, schizoaffective and bipolar I disorder. Also being tested are different concentrations of Intravail A3. Intravail A3 belongs to a class of nonionic surfactants known as alkylglycosides. Alkylglycosides have been extensively studied for their ability to promote increased bioavailability of drugs via the nasal, oral, and ocular routes.

In this study it will be tested if the olanzapine in the two Test products will show comparable pharmacokinetics, safety and tolerability in comparison to the Reference product through the primary pharmacokinetic parameters Cmax, AUC from time 0 to time t and AUC from time 0 to infinity, and safety assessments, including nasal irritation, sedation and pain scales.

• Subjects who donated blood or plasma within 3 months of the first dose of study drug.
• Participation in a bioequivalence study or in a clinical trial with IP administration within 80 days prior to the first dose of study drug.

• Use of any prescription or over the counter (OTC) medication within 30 days prior to the first dose of study drug or during the study.
• Positive blood screen for HIV, Hepatitis B surface antigen (HbSAg), or Hepatitis C, or a positive screen for alcohol or drugs of abuse.
