Indivior Announces NDA Acceptance of RBP-7000 Risperidone Monthly Depot

A Novel Sustained-Release Candidate for Treatment of Schizophrenia

Slough, UK and Richmond, VA, 12 December 2017 – Indivior PLC (LON: INDV) (the ‘Company’) today announces that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for RBP-7000, an investigational, once-monthly injectable risperidone in the ATRIGEL® delivery system for the treatment of schizophrenia.  The NDA, which was submitted on September 28, 2017, is based on data from the pivotal Phase 3 study assessing clinical efficacy and safety and from the long-term safety study of RBP-7000. The FDA has set a PDUFA (Prescription Drug User Fee Act) target action date of July 28, 2018.

“FDA acceptance of our RBP-7000 NDA is a significant milestone for Indivior as we expand our treatment portfolio to offer a meaningful therapeutic option to help address non-compliance with medication administration in the treatment of schizophrenia,” said Christian Heidbreder, Ph.D., Chief Scientific Officer of Indivior. “We look forward to closely working with the Agency during the review process to support the approval of RBP-7000 and to provide both physicians and patients this innovative treatment option.”

This NDA submission includes the results from the pivotal Phase 3 study (RB-US-09-0010) assessing the efficacy and safety of RBP-7000 and an open-label, long-term safety study (RB-US-13-0005). In the pivotal randomized, double-blind, placebo-controlled study, RBP-7000 demonstrated statistically significant clinical improvement compared to placebo based on changes in mean Positive and Negative Syndrome Scale (PANSS) total and Clinical Global Impression-Severity of Illness (CGI-S) scores at 8 weeks.

About RBP-7000


RBP-7000 is a novel extended-release product using the ATRIGEL® delivery system for the subcutaneous (SC) administration of risperidone once monthly for the treatment of schizophrenia.

The results of the pivotal Phase 3 studies to assess the efficacy, safety and tolerability of RBP-7000 in subjects with acute schizophrenia were recently published.1.2

The most common adverse reactions in clinical trials (reported in ≥ 5% and greater than placebo group) were weight increase, constipation, sedation/somnolence, pain in extremity, back pain, akathisia, anxiety and musculoskeletal pain. The most common injection site reactions (≥ 5%) were injection site pain, erythema and induration/nodule.

About Schizophrenia

Schizophrenia is a chronic disorder characterized by a life-long pattern of acute psychotic episodes superimposed upon chronically poor psychosocial adjustment. The symptoms can be grouped into four domains: positive (for example, delusions, hallucinations, disorganized speech and behavior); negative (for example, social withdrawal, avolition, blunted effect); cognitive (for example, impaired sustained attention, executive function and working memory) and affective (for example, anxiety and depression, hostility and aggression, increased risk of suicide) symptoms. These occur in different combinations and to a different degree in each patient. Given the extensive heterogeneity of symptoms among individual patients, schizophrenia can be considered a clinical syndrome rather than a single disease entity. An estimated 23 million people worldwide in 2015 were affected with schizophrenia.3
