NRX-1074 in Early Course Schizophrenia
A Placebo-controlled Two-dose Trial of NRX-1074 Early in the Course of Schizophrenia
Study Overview
Detailed Description
Investigators propose to conduct a 4-week, randomized, double-blind, placebo-controlled trial in which NRX-1074 will be intravenously administered twice. Subjects will be 62 stable patients ages 18-50 within five years of onset of schizophrenia, treated with any antipsychotic except clozapine at an adequate, stable dose for at least 8 weeks. This study will be conducted by the Schizophrenia Program of the NYU Langone Medical Center and at the Psychiatry Outpatient Clinic of Bellevue Hospital located in New York, NY.
Upon signing consent, patients will undergo screening procedures to assess eligibility. A diagnosis of schizophrenia or schizophreniform disorder will be determined by the Structured Clinical Interview for DSM IV (SCID) completed by a research clinician using all available clinical data and will be confirmed by consensus diagnosis. A comprehensive medical review and physical exam, including routine laboratory tests, will be completed to identify unstable medical illness. A urine toxicology screen and, in females, a pregnancy test will also be performed. A research assistant will complete the Logical Memory Test portion of the Weschler Memory Scale-III (WMS-III).
Subjects who meet study eligibility criteria will complete the baseline visit which will include a one minute infusion of NRX-1074 and the following clinical assessments: Brief Psychiatric Rating Scale (BPRS), Clinical Assessment Interview for Negative Symptoms (CAINS), Calgary Depression Scale for Schizophrenia (CDSS), InterSePT Scale for Suicidal Thinking (ISST), Clinical Global Impression (CGI), and Systematic Assessment for Treatment Emergent Events (SAFTEE). The BPRS, SAFTEE, and ISST will be conducted twice, both before and after the infusion. The remaining assessments will be conducted before the infusion. A cognitive assessment, the Logical Memory Test of the WMS-III, will also be conducted after the infusion.
Patients will return for a visit one day after their baseline infusion, where the BPRS, ISST, CGI, and Logical Memory Test will be conducted. Their next visit will be one week later, where they receive their second NRX-1074 infusion, and will be similar in format to the first baseline infusion with the exception of CAINS and CDSS. One day after the second infusion, patients will be administered the BPRS, CAINS, CDSS, ISST, CGI, and MATRICS Consensus Cognitive Battery (MCCB). Patients will then return weekly for three weeks until Day 28.
The BPRS and ISST will be conducted during the Baseline, Day 1, Day 7, Day 8, Day 14, Day 21, and Day 28 visits. The CGI will be administered during Baseline, Day 1, Day 7, Day 8, Day 14, and Day 28. The CAINS and CDSS will be administered at Baseline, Day 8, Day 14, and Day 28. The SAFTEE will be conducted on Baseline, Day 7, Day 14, Day 21, and Day 28. The Logical Memory Test will be administered during Screening Visit 1, Screening Visit 2, Baseline, and Day 1. The MATRICS will be conducted on Day 8 and Day 28.
The primary outcome measure is the change in BPRS total score from Baseline to 24 hours post infusion on Day 8. Secondary outcome measures include the positive and negative symptom subscales on the BPRS, the CAINS total score, the composite score on the MATRICS 24 hours after the second infusion and the Logical Memory Test compared to placebo one hour after the first infusion (Baseline).
