A Clinical Study to Evaluate the Bioavailability Between Two Products Containing Paliperidone 100 mg in the Form of a Prolonged Release Suspension for Injection in Patients With Schizophrenia Who Are Already Stabilized in This Treatment
Α Randomized, Two-way, Two-treatment, Two-period, Crossover, Open Label, Laboratory-blind, Comparative Bioavailability Study at Steady State Between Paliperidone 100 mg Prolonged Release Suspension for Injection (Test Product) and Xeplion® 100 mg Prolonged Release Suspension for Injection (Reference Product) Following Multiple Intramuscular Injections (Five Doses in Each Period, One Dose Every 28 Days) Administration to Patients With Schizophrenia Who Are Already Receiving a Stable Regimen of Paliperidone Prolonged Release Suspension Via The Intramuscular Route

Detailed Description
This study will be a randomized, two-way, two-treatment, two-period, crossover, open label, laboratory-blind, multiple dose study at steady state, under fasting conditions.
To main purpose of this study is to determine the relative bioavailability of Paliperidone 100 mg prolonged release suspension for injection (Pharmathen S.A, Greece) and Xeplion® (Paliperidone) 100 mg Prolonged Release Suspension for Injection (Janssen Pharmaceutica N.V., Belgium) following multiple Intramuscular Injections (five doses in each period, one dose every 28 days) administration to patients with schizophrenia who are already receiving a stable regimen of paliperidone prolonged release suspension via the intramuscular route.
The secondary objective of this study is to evaluate the safety and tolerability between the two products.
Five injections of Paliperidone 100 mg prolonged release suspension will be administered intramuscularly (in the deltoid muscle) to study patients in each period (one injection every 28 days).
A total of 70 patients will be randomized into two sequences (Test-Reference or Reference-Test).
The doses will be administered to study patients in each period, according to the randomization plan , as clarified in the table below:
Period I Day 0 First dose Day 28 Second dose Day 56 Third dose Day 84 Fourth dose Day 112 Fifth Dose
Period II Day 140 First dose Day 168 Second dose Day 196 Third dose Day 224 Fourth dose Day 252 Fifth Dose
Following up the last dose of each period, a series of blood samples will be collected from each patient in order to determine the bioavailability of the received drug. More specifically, patients will return to the clinical site to give the scheduled PK blood samples on Day 113, Day114, Day 115, Day 116, Day 117, Day 118, Day 119, Day 120, Day 121, Day 122, Day 123, Day 124, Day 125, Day 126, Day 127, Day 128, Day 129, Day 130, Day 132, Day 134, Day 136, Day 138, Day 253, Day 254, Day 255, Day 256, Day 257, Day 258, Day 259, Day 260, Day 261, Day 262, Day 263, Day 264, Day 265, Day 266, Day 267, Day 268, Day 269, Day 270, Day 272, Day 274, Day 276, Day 278 and Day 280.

Description
Inclusion Criteria:
- The patient is suffering from Schizophrenia.
- The patient age is > 18 years and < 65 years old (inclusive).
- The patient has a body weight not less than 50 Kg and according to the BMI range (18.5 - 35 Kg/m2), (inclusive)
- The patient has received at least 3 doses of Paliperidone 100 mg Prolonged Release Suspension for Injection within the last 3 months.
- The patient is under fasting conditions (food and drinks) for at least 8 hours on the day of screening.
- The patient is available to volunteer for the entire study duration and is willing to adhere to all protocol requirements.
- The findings of the patient are within the range of clinical acceptability in medical history, physical examination, vital signs, ECG, and laboratory results.
- The legally acceptable representative signed the informed consent form and the patient is able to communicate with the investigator and comprehend study-related procedures.
- The patient agrees to use a condom if he is engaged in sexual activity with a woman of childbearing potential.
A condom is required along with another medically acceptable contraceptive method. Medically acceptable methods of contraception include non-hormonal intrauterine device or double barrier method (condom with foam or vaginal spermicidal suppository, diaphragm with spermicide).
- Female patients may be included but must comply with the following in order to be included:
- Women having the potential to become pregnant can be enrolled only if willing to use a clinically acceptable (i.e. intrauterine device or hormonal contraceptives for at least three months) or a double barrier contraceptive measure (i.e. condom and spermicidal gel or diaphragm and spermicidal gel for at least 14 days) prior to the start of the study and through the study and for 30 days after completion of the study, or
- Surgically sterilized for at least 6 months or
- Menopausal women, for at least 1 year
Exclusion Criteria:
- The patient is pregnant or nursing (lactating) women, where pregnancy is defined as the state of the female after conception and until the termination of gestation, confirmed by a positive urine or serum pregnancy test.
- The patient has any significant or organ abnormality as determined by the principal investigator/sub-investigator.
- The patient has skin abnormalities/irritations at the potential injection site (right or left deltoid) as determined by the Principal Investigator/clinical Sub-Investigator.
- The patient has a medical or surgical condition that might interfere with the absorption, metabolism, or excretion of paliperidone.
- The patient has known allergy to the Paliperidone Palmitate or to any ingredient in the preparation.
