Detailed Description
This is a phase II proof of concept (POC), multi-center, prospective, randomized, placebo-controlled, Sequential Parallel Comparison Design (SPCD) study, in which a total of 60 subjects with schizophrenia will be enrolled.
The study will be conducted in two stages. The study treatment will be administered in a double-blind fashion for all subjects throughout both stages of the study. A total of 60 subjects with schizophrenia will be randomized in a 1:1:1 ratio to drug-drug sequence [n=20; i.v. sodium nitroprusside (0.5 μg/kg/min for 4 hours) at week 0 and week 2], placebo-drug sequence [n=20; i.v. placebo at week 0 and i.v. sodium nitroprusside (0.5 μg/kg/min for 4 hours) at week 2], and placebo-placebo sequence [n=20; i.v. placebo at week 0 and again at week 2]. The 4-week double-blind phase of treatment will be divided into two phases: Phase 1, from week 0 to week 2, and Phase 2 from week 2 to week 4. At the end of Phase 1 (week 2), the randomized subjects will be assessed and categorized into responders and non-responders, based on 20% or more reduction from baseline in their PANSS total score as per the evaluations at Randomization Visit (week 0). The data from the patients deemed placebo non-responders in phase 1 who go on to either stay on placebo or to receive treatment with sodium nitroprusside will be pooled with the data from Phase 1 from all subjects, according to SPCD.

Description
Inclusion Criteria:
Each subject must meet all of the following criteria to be eligible for this study:
- Males or Females aged 18-65 years inclusive.
- Primary diagnosis of Schizophrenia established by a structured psychiatric evaluation (SCID) based on Diagnostic and Statistical Manual of Mental Disorders Forth Edition (DSM-IV-TR) criteria.
- Written informed consent in compliance with 21 CFR part 50 and in accordance with the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) Guidelines.
- A Positive and Negative Syndrome Scale (PANSS) (Kay et al., 1994) total score ≥ 70 with a score of > 4 on two or more of the following PANSS items: delusions, conceptual disorganization, hallucinatory behavior, suspiciousness, and unusual thought content.
- A score of ≥4 on the Clinical Global Impression-Severity (CGI-S) (Guy, 1976).
- Confirmation of both diagnosis and severity of psychosis symptoms by an independent MGH SAFER interview.
- Must have ongoing antipsychotic treatment for at least 8 weeks, with a stable dose for at least 4 weeks. Subjects who have failed to achieve clinically-recognized symptom reduction to at least 1 marketed antipsychotic agent, given at a Physician Desk Reference (PDR)-defined therapeutic dose for ≥ 8 weeks during the past 12 months, as assessed by the MGH FAST, will be eligible
- Understands and is able, willing, and (in the opinion of the investigator) likely to fully comply with the study procedures and restrictions.
Exclusion Criteria
Subjects who meet any of the following criteria will be excluded from the study:
- Subjects with a history of renal insufficiency, congestive heart failure, cardiac arrhythmias or history of myocardial infarction.
- Subjects with a history of symptomatic orthostatic hypotension defined as sitting to standing systolic blood pressure < 90mmHg or diastolic blood pressure < 60mm Hg with any of the following symptoms: lightheaded or dizzy upon standing, blurry vision, weakness, fainting (syncope), confusion, or nausea.
- Subjects with any clinically significant abnormalities as determined by medical history, physical exam, clinical and lab evaluation suggestive of an underlying disease state that may, in the opinion of the investigator, confound the results of study, increase risk to the subject, or lead to difficulty complying with the protocol.
- Subjects on chlorpromazine, PDE-5 inhibitors, nitrites and any medication with CNS effects with the exception of antipsychotic drugs (other than chlorpromazine) anticholinergics, b-adrenergic antagonists, amantadine, biperiden, diphenhydramine, lorazepam, zolpidem, and temazepam.
- Medications which in the opinion of the PI, and in conjunction with the medical monitor, may be expected to significantly interfere with the metabolism or excretion of sodium nitroprusside, and/or may be associated with a significant drug interaction with sodium nitroprusside that may pose a significant risk to subjects' health and/or confound the study data.
- Pregnant or breast-feeding patients. Women of childbearing potential must have a negative pregnancy test performed at screening visit prior to randomization and prior to baseline at visits 3 and 6. Women enrolled in this trial must use adequate birth control.

- Has tested positive for any of the following: cannabis, opioids, cocaine, amphetamines, barbiturates methadone, methamphetamine and phencyclidine at the screening or baseline visits. If positive, the urine drug toxicology screen may be repeated once based on investigator judgment, but due to safety concerns, the result must be negative for the subject to continue in the study.
- Subjects at imminent risk of suicide or injury to self or others, as per the opinion of the investigator, or history of significant suicide attempt within the last 6 months as per C-SSRS.
- Subjects that have taken an investigational drug or taken part in a clinical trial within 30 days prior to screening.
- Any other reason that, in the opinion of the investigator, would compromise patient safety or integrity of the study

Change in the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) - Phases 1 and 2
Time Frame: Phase 1 timeframe is Baseline and Day 14; Phase 2 timeframe is Day 14 and Day 28
|
MATRICS: The Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB).
The MATRICS Consensus Cognitive Battery is the standard tool for assessing cognitive change in trials of cognitive-enhancing agents in schizophrenia.
The MCCB domains include: Speed of Processing; Attention/Vigilance; Working Memory; Verbal Learning; Visual Learning; Reasoning & Problem-Solving; and Social Cognition and the battery takes about 80 minutes to complete.
The MCCB composite score represents a global measure of cognition.
MCCB composite T scores are between 40 and 60 (normal range) and < 40 (below normal range).

|
Abnormal Involuntary Movement Scale (AIMS): The AIMS Total Dyskinesia Score was calculated by averaging the first 7 items of the AIMS. The 7 items included in the AIMS Dyskinesia Score are rated on a scale from 0 (no dyskinesia) to 4 (severe dyskinesia). Items 1 through 7 include facial and oral movements (Items 1-4), extremity movements (Items 5-6), and trunk movements (Item 7). The AIMS dyskinesia total score ranges from 0 to 4; a higher score reflects increased severity. |

Time Frame: Screening Visit, Days 3 (Baseline 1), Days 7, 13 (Baseline 2), 21 and 28
|
The Columbia Suicide Severity Rating Scale (C-SSRS): The C-SSRS is a low-burden measure of the spectrum of suicidal ideation and behavior that was developed in the National Institute of Mental Health Treatment of Adolescent Suicide Attempters Study to assess severity and track suicidal events through any treatment.
It is a clinical interview providing a summary of both ideation and behavior that can be administered during any evaluation or risk assessment to identify the level and type of suicidality present.
The C-SSRS can also be used during treatment to monitor for clinical worsening or improvement.
It contains 5 rating scale questions (yes/no) for suicidal ideation increasing severity and 5 rating scale questions (yes/no) for suicidal behavior of increasing severity.
The time frame is for both lifetime and the past six months for the Baseline/Screening scale and since the last visit for the Since Last Visit scale.
