Primary Objective: To assess the relative bioavailability of RBP-7000 formulated with 2 different molecular weights (MW) (low and high MW as test treatments) of poly (DL-lactide-co-glycolide) with a carboxylic acid end group (PLGH) polymer compared to intermediate MW PLGH polymer following single subcutaneous (SC) injection of RBP-7000 in subjects with stable schizophrenia.
