Brief Summary  
This is a randomized, open label, two stage, multicenter, parallel group, multiple dose, steady state study to compare the bioavailability and characterize the pharmacokinetic profile of the test formulation [Paliperidone Palmitate extended release injectable suspension, (546 mg/1.75 mL), by Accord Healthcare Inc., USA administered every three months] relative to that of the reference formulation [Invega® Trinza® (Paliperidone Palmitate extended release injectable suspension, 546 mg/1.75 mL), by Janssen Pharmaceuticals, Inc., Titusville, New Jersey, USA] and establish bioequivalence in patients with Schizophrenia already receiving a stable regimen of paliperidone palmitate extended release injectable suspension. 
A target of 360 participants will be randomly assigned in this study with 180 participants planned per intervention group. 
The study will be conducted in below mentioned phases :
• A 14-day screening phase: Screening assessments will be performed within 14 days prior to the initiation of stabilization procedures OR within 14 days of the first Investigational Medicinal Product (IMP) administration on Day 1 of treatment period. 
• Stabilization Phase of maximum up to 4 months (as applicable) 
• Treatment phase of total 4 dose of 3 monthly injection of test or reference product. Extensive  blood samples (covers a complete dosing interval) will be taken for PK characterization after 4th dose."
