PP1M is commercially manufactured.
NanoCrystal® Colloidal Dispersion Nanomill™ apparatus.
NanoCrystal technology enables intrinsically high loading of insoluble drugs as dosage forms consist mostly of pure API packed as a solid crystal, which is the most efficient form possible in relation to weight-to-volume. Paliperidone palmitate particles are dispersed in an aqueous suspension and transformed into smaller nanocrystals through particle-size reduction. These nanocrystals have a greater surface area than the larger original particles, resulting in increased water solubility. This medicinal product does not require any special storage conditions and has a shelf life of two years.
Digital microscope and scanning electron microscopy (SEM) to determine shape of the particles. Differential scanning calorimetric (DSC) and Fourier transforms infrared spectroscopy (FTIR) for quality control.

This multicenter, randomized, open-label, parallel-group, multiple-dose study is designed to evaluate the bioequivalence, at pharmacokinetic steady state, of a paliperidone palmitate injection manufactured by CSPC Zhongnuo Pharmaceutical (Shijiazhuang) Co., Ltd. (Test Group) and a paliperidone palmitate injection manufactured by Janssen Pharmaceutica N.V. (Reference Group) in patients with schizophrenia in China. Bioequivalence will be assessed based on steady-state pharmacokinetic parameters after repeated intramuscular administration (e.g., Cmax,ss and AUCτ). The safety and tolerability of the test and reference products will also be evaluated.

Calo Psychiatric Center
Schizophrenia is a chronic and severe psychiatric disorder, these patients suffer from positive symptoms, negative symptoms and cognitive deficits, of which working memory problems are considered a central cognitive impairment. Atypical antipsychotics are believed to have a superior effect in reducing both positive and negative symptoms of schizophrenia, coupled with a low risk of extrapyramidal symptoms. Particularly, 2nd-generation antipsychotic medications are commonly used in treatment of schizophrenia. An antipsychotic drug, Paliperidone palmitate (PDP), is administered to patients with schizophrenia as injections at one-month (PP1M) or three-month (PP3M) intervals. This study was compare the effects of treatment, social function, and side effects between PP1M and PP3M in patients wit

Bishara D. Once-monthly paliperidone injection for the treatment of schizophrenia. Neuropsychiatr Dis Treat. 2010 Sep 7;6:561-72. doi: 10.2147/NDT.S8505. PMID: 20856919; PMCID: PMC2938305.
Paliperidone palmitate is a new long-acting antipsychotic injection for the treatment of acute and maintenance therapy in schizophrenia. Paliperidone (9-hydroxyrisperidone) is the major active metabolite of risperidone and acts at dopamine D2 and serotonin 5HT2A receptors. As with other atypical antipsychotics, it exhibits a high 5HT2A:D2 affinity ratio. It also has binding activity as an antagonist at α1-and α2 adrenergic receptors and H1 histaminergic receptors, but has virtually no affinity for cholinergic receptors. Paliperidone palmitate has been shown to be effective in reducing Positive and Negative Syndrome Scale total scores in four short-term trials in acute schizophrenia. It was also effective as maintenance therapy in a long-term trial in which time to recurrence of symptoms was significantly longer in paliperidone-treated patients compared with placebo. In addition, paliperidone was shown to be noninferior to risperidone long-acting injection in one study, but this noninferiority was not established in another longer study comparing the two drugs. Treatment should be initiated with 234 mg on day 1 and 156 mg on day 8, followed by a recommended monthly maintenance dose of 39–234 mg based on efficacy and tolerability. Paliperidone palmitate is generally well tolerated, although it can cause weight gain and a rise in prolactin levels, which is generally greater in women than in men. Overall, paliperidone palmitate may have advantages over other currently available long-acting injections, and therefore may be a useful alternative for the treatment of schizophrenia, although further long-term trials comparing it with active treatments are warranted.

Three bioequivalence studies were conducted to compare Niapelf (a generic paliperidone palmitate prolonged-release injectable suspension) to the reference PP1M product. Two pivotal studies (TOL3033D and TOL3033B) demonstrated bioequivalence through 90% CIs for geometric LS mean ratio of test vs. reference within the acceptance range of 80.00%-125.00% for PK parameters (e.g. AUC0-∞, AUC0-τ, Cmax,ss and Cτ,ss). The TOL3033A study was considered supportive due to a lack of statistical power after excluding a significant number of subjects following methodological deficiencies and GCP non-compliance. Notably, the test product (Niapelf) exhibits consistently lower exposure across all three BE studies (TOL3033D, TOL3033B, TOL3033A), however it was considered unlikely to be of clinical relevance.
