This requires: • all patients taking clozapine, the physician must have obtained consent from the patient; and registration of the patient, their current location, treating physician, testing laboratory and dispensing pharmacist in the JAMP Clozapine Risk Management Program system.
• maintenance of a national JAMP Pharma Corporation monitoring system of the hematological results of all patients on JAMP Clozapine and provides timely feedback (within 24 hours of receipt of the blood test results) to the treating physician and dispensing pharmacist/or pharmacy • the ability to identify patients who have been assigned "Non-rechallengeable Status" (see 7 WARNINGS AND PRECAUTIONS).
This requires that JAMP Pharma Corporation both provide to, and obtain from, all other approved suppliers † of clozapine, the Non- rechallengeable Status / Hematological Status of all patients (see 4 DOSAGE AND ADMINISTRATION). JAMP Pharma Corporation must be able to provide this information within 24 hours of receiving a written request.
† “approved supplier” is a manufacturer who holds a valid Notice of Compliance (NOC) for clozapine JAMP Clozapine (Clozapine Tablets) Product Monograph Page 5 of 48 Physicians should not prescribe JAMP Clozapine until the non-rechallengeable status and the hematological status of the patient has been verified.

1 Adverse Reaction Overview The most serious adverse reactions experienced with clozapine tablets are neutropenia seizure, cardiovascular effects and fever (see 7 WARNINGS AND PRECAUTIONS, Hematologic). The most common side effects are drowsiness/sedation, dizziness, hypersalivation, tachycardia, and constipation.
Adverse Events Leading to Discontinuation Of 1080 patients who received clozapine in premarketing clinical trials, 16% discontinued treatment due to an adverse event, including both those that could be reasonably attributed to clozapine JAMP Clozapine (Clozapine Tablets) Product Monograph Page 24 of 48 treatment and those that might more appropriately be considered intercurrent illness.
The more common events considered to be causes of discontinuation included:
CNS (psychotic disorder), primarily drowsiness/sedation, somnolence, seizures, dizziness (excluding vertigo)/syncope; cardiovascular, primarily tachycardia, hypotension and ECG changes; gastrointestinal, primarily nausea/vomiting; hematologic, primarily neutropenia and fever.
7% of all discontinuations attributed to adverse clinical event. Most Frequent Adverse Events Adverse events observed in association with the use of clozapine in clinical trials at an incidence of greater than 5% were: central nervous system complaints, including drowsiness/sedation, dizziness/vertigo, headache and tremor; autonomic nervous system complaints, including salivation, sweating, dry mouth and visual disturbances; cardiovascular findings, including tachycardia, hypotension and syncope; and gastrointestinal complaints, including constipation and nausea; and fever.
Complaints of drowsiness/sedation tend to subside with continued therapy or dose reduction. Salivation may be profuse, especially during sleep, but may be diminished with dose reduction. 2 Clinical Trial Adverse Reactions The following table enumerates adverse events that occurred at a frequency of 1% or greater among clozapine patients who participated in clinical trials.

The introduction of clozapine from other manufacturers has now resulted in the establishment of manufacturer- specific registry and distribution systems. In order to ensure the safe use and continued monitoring of all patients taking clozapine, the physician must have obtained consent from the patient for the potential sharing of hematological and other safety data between clozapine registries.
Patients may not be switched from one brand of clozapine to another without the completion of a new registry-specific patient registration form signed by the prescribing physician. If a patient is switched from one brand of clozapine to another, the frequency of hematological monitoring may continue unaltered unless a change is clinically indicated.
