Janssen Pharma’s Byannli (PP6M) receives European approval for Maintenance Treatment of Schizophrenia in Adults.

The Janssen Pharmaceutical Companies of Johnson & Johnson announced the approval of the long-acting atypical antipsychotic therapy Byannli (6-monthly paliperidone palmitate; PP6M) by the European Commission (EC) for the maintenance treatment of schizophrenia in adult patients who are clinically stable on 1-monthly paliperidone palmitate (PP1M) or 3-monthly paliperidone palmitate (PP3M).

“With only two injections per year, 6-monthly paliperidone palmitate has the potential to reduce the burden of taking medication frequently, giving eligible patients the opportunity to focus on other aspects of their life,” said Ludovic de Beaucoudrey, Ph.D., EMEA Therapeutic Area Lead, Janssen-Cilag. “This Positive Opinion from the CHMP underscores Janssen’s 60-year commitment to transforming the lives of people living with schizophrenia through rigorous scientific research and product development.”

The European Commission approval is based on the Route 6 Study, a randomised, double-blind, non-inferiority Phase 3 global study designed to demonstrate that PP6M is not less effective than PP3M for the prevention of relapse in participants previously stabilised on a shorter-acting formulation of paliperidone palmitate. The study enrolled 702 adults living with schizophrenia from 20 countries, including Bulgaria, Czech Republic, France, Hungary, Italy, Poland, Russia, Spain and Turkey. The results showed non-inferiority of PP6M compared with PP3M on the primary endpoint of time to first relapse at the end of the 12-month period. Results found that 92.5 percent of patients treated with PP6M and 95.1 percent treated with PP3M were relapse-free at 12 months. Relapse was defined as psychiatric hospitalisation, increase in Positive and Negative Syndrome Scale (PANSS) total score, increase in individual PANSS item scores, violent behaviour resulting in self-injury or suicidal/homicidal ideation.

“When it comes to the treatment of schizophrenia, unmet needs remain, including treatment adherence concerns, despite currently available therapies,” said Bill Martin, Ph.D., Global Therapeutic Area Head, Neuroscience, Janssen Research & Development, LLC. “The Positive Opinion received from the CHMP today, enables us to rethink how we manage this chronic disease and brings us one step closer to offering patients and caregivers the potential for a life less defined by medication.”

The safety profile observed for PP6M was consistent with previous studies of PP1M and PP3M with no new safety signals emerging. The most common treatment emergent adverse reactions (≥5.0 percent) in the study’s PP6M group were weight increase (8.4 percent), injection site pain (7.7 percent), headache (6.7 percent) and upper respiratory tract infection (5.0 percent). There were no unexpected serious adverse reactions.

“Non-adherence to prescribed drug treatments has been recognised as a challenge for treatment continuity that can potentially have a negative impact on treatment outcomes,” said Professor Silvana Galderisi,* Route 6 Study Investigator and Professor of Psychiatry and Director of the Emergency Unit of the Department of Mental Health at the University of Campania Luigi Vanvitelli, Italy. “It is therefore essential to provide a variety of treatment options to meet different patient needs. If approved by the European Commission, PP6M’s extended dosing interval may help address a key unmet need within this population.”

Following this Positive CHMP Opinion, the European Commission will now consider approval of a marketing authorisation for PP6M as a long-acting injectable maintenance treatment for adults with schizophrenia who are clinically stable on 1‑monthly or 3‑monthly paliperidone palmitate injectable products. The European Commission has the authority to grant marketing authorisation for medicines in the European Economic Area.

About the Route 6 Study (PSY3015):

The Route 6 Study was a randomised, double-blind, non-inferiority global Phase 3 study of 702 adults (ages 18–70) with schizophrenia, designed to demonstrate that injection cycles consisting of a single administration of PP6M (700 or 1000 mg) are not less effective than two sequentially administered injections of PP3M (350 or 525 mg) for the prevention of relapse in subjects with schizophrenia previously stabilised on corresponding doses of PP1M (100 or 150 mg) or PP3M (350 or 525 mg).

The study consisted of four treatment phases: a screening phase (up to 28 days); a transition phase (of 1 to 4 months), applicable to those adult patients who entered the screening phase before being stabilised on PP1M or PP3M; a maintenance phase (of 1 or 3 months), used to stabilise patients on PP1M or PP3M prior to the double-blind phase; and a double-blind phase (of 12 months).

In the double-blind phase all stabilised adult patients (N=702) were randomised in a 2:1 ratio to receive PP6M (n=478) or PP3M (n=224).

Study evaluations included efficacy, pharmacokinetics, pharmacodynamics and safety. The study’s duration varied from approximately 13 months to 19 months depending on treatment arm.

About Long-Acting Injectables:

Long-acting injectables (LAIs) allow for the slow release of a drug into the blood and have been on the market for more than 50 years. LAI antipsychotics have been demonstrated to offer a number of advantages compared with oral medication, including not having to remember to take drugs daily, improved patient outcomes, improved patient and physician satisfaction, and lower relapse rates.

In 2002, a 1‑monthly injectable formulation (PP1M) was approved by the European Commission as a maintenance treatment of schizophrenia in adult patients under the brand name XEPLION®. In 2016, a 3-monthly LAI formulation (PP3M) was approved under the trade name TREVICTA®.

About Paliperidone palmitate:

Paliperidone is chemically 3-{2-[4-(6-fluoro-1,2-benzoxazol-3-yl)piperidin-1-yl]ethyl}-2-methyl-4-oxo-6,7,8,9-tetrahydropyrido[1,2-a]pyrimidin-9-yl hexadecanoate is a fatty acid ester obtained by the formal condensation of the carboxy group of hexadecanoic acid with the hydroxy group of 3-{2-[4-(6-fluoro-1,2-benzoxazol-3-yl)piperidin-1-yl]ethyl}-9-hydroxy-2-methyl-6,7,8,9-tetrahydropyrido[1,2-a]pyrimidin-4-one. It is a member of 1,2-benzoxazoles, a heteroarylpiperidine, an organofluorine compound, a pyridopyrimidine and a fatty acid ester.

Paliperidone, sold under the trade name Invega among others, is an atypical antipsychotic. It is mainly used to treat schizophrenia and schizoaffective disorder.

It is marketed by Janssen Pharmaceuticals. An extended release formulation is available that uses the OROS extended release system to allow for once-daily dosing. Paliperidone palmitate is a long-acting injectable formulation of paliperidone palmitoyl ester.


Paliperidone is the primary active metabolite of the older antipsychotic risperidone. While its specific mechanism of action is unknown, it is believed paliperidone and risperidone act via similar, if not identical, pathways. Its efficacy is believed to result from central dopaminergic and serotonergic antagonism. Food is known to increase the absorption of Invega type ER OROS prolonged-release tablets. Food increased exposure of paliperidone by up to 50-60%, however, half-life was not significantly affected. The effect was probably due to a delay in the transit of the ER OROS formulation in the upper part of the GI channel, resulting in increased absorptio

History of Paliperidone palmitate:

Paliperidone (as Invega) was approved by the Food and Drug Administration (FDA) for the treatment of schizophrenia in 2006. Paliperidone was approved by the FDA for the treatment of schizoaffective disorder in 2009. The long-acting injectable form of paliperidone, marketed as Invega Sustenna in U.S. and Xeplion in Europe, was approved by the FDA on July 31, 2009. It is the only available brand in Bangladesh under the brand name “Palimax ER” manufactured & marketed by ACI Pharmaceuticals.

It was initially approved in Europe in 2007 for schizophrenia, the extended release form and use for schizoaffective disorder were approved in Europe in 2010, and extension to use in adolescents older than 15 years old was approved in 2014.

About Schizophrenia:

Schizophrenia is a chronic and severe brain disorder affecting approximately 20 million people worldwide and an estimated 3.7 million people in the EU. The disease is characterised by distortions in thinking, perception, emotions, language, sense of self and behaviour leading to neurological impairment, severe disability and increased mortality.

Antipsychotic medication is recognised as an essential component in the treatment of schizophrenia, and adherence to medication plays a critical role in preventing symptoms and relapses. Early intervention in schizophrenia may improve patient outcomes as more than 69 percent of people with schizophrenia do not receive appropriate care.
