Study Endpoints

Primary Endpoints

Participants With Treatment-Emergent Adverse Events (TEAE)
Day 1 up to week 52

An adverse event (AE) is defined as any study-related event that represents a change (positive or negative) in frequency or severity from a baseline (prestudy) event (if any), regardless of the presence of causal relationship or medical significance. Treatment-emergent adverse events are defined as any adverse event with a start date on or after the first study dose date. AEs are determined by the Investigator to be related or not related to the study drug. A serious AE (SAE) is defined by federal regulation as any AE occurring at any dose that results in any of the following outcomes: death, life-threatening AE, hospitalization or prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth defect. Although a subject may have had 2 or more adverse experiences the subject is counted only once in a category. The same subject may appear in different categories.

Participants With Injection Site-Related Treatment-Emergent Adverse Events (TEAEs)
Day 1 up to week 52

An adverse event (AE) is defined as any study-related event that represents a change (positive or negative) in frequency or severity from a baseline (prestudy) event (if any), regardless of the presence of causal relationship or medical significance. Treatment-emergent adverse events are defined as any adverse event with a start date on or after the first study dose date. Adverse events were coded using MedDRA version 17.0. Preferred terms linked to injection site AEs are reported. Although a participant may have had 2 or more AEs, the subject is counted only once in each preferred term category. The same subject may appear in different preferred term categories.

Participants With Markedly Abnormal Weight Gain Anytime During the Study as Compared to Baseline
Baseline (Day 0), Treatment (Day 1 up to Week 52)

Participants who were found to have gain \>=7% and \>=10% of their baseline weight at any point during the study (including unscheduled assessments) once treatment began.

Mixed Model for Repeated Measures (MMRM) Analysis of Change From Baseline to End of Treatment in the Positive and Negative Syndrome Scale (PANSS) Total Score
Day 1 prior to treatment (Baseline), Days 15, 29, 43 and 57 or early discontinuation

The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor judgement, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score is the sum of all 30 PANSS items and ranges from 30 to 210, with 30 indicating absence of symptoms of schizophrenia and 210 indicating extreme ratings of all 30 symptoms. Negative change from baseline scores indicate improvements in symptoms. Estimates (least square means and standard errors), 2-sided confidence intervals, and -1-sided P values are based on a repeated-measures linear regression model of the change from baseline score, with fixed effects for visit as a categorical variable, baseline score, treatment and treatment by visit interaction, assuming an unstructured covariance matrix.

Day 1 to Day 106

An adverse event (AE) is defined as any study-related event that represents a change (positive or negative) in frequency or severity from a baseline (prestudy) event (if any), regardless of the presence of causal relationship or medical significance. Treatment-emergent adverse events are defined as any adverse event with a start date on or after the first study dose date. AEs are determined by the Investigator to be related or not related to the study drug. A serious AE (SAE) is defined by federal regulation as any AE occurring at any dose that results in any of the following outcomes: death, life-threatening AE, hospitalization or prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth defect. Although a subject may have had 2 or more adverse experiences the subject is counted only once in a category. The same subject may appear in different categories.

Interventions

NameTypeDescription
RBP-7000DRUG120-mg RBP-7000 dose delivered by subcutaneous injection every 28 days for a total of 13 injections (for roll-over participants, the first two injections took place under study RB-US-09-0010). A one-time down-titration to 90 mg RBP-7000 is permitted at the investigator's discretion should the participant have tolerability issues. Participants who received the 90-mg dose of RBP-7000 and exhibited a worsening in psychiatric symptoms could receive a one-time up-titration back to 120 mg RBP-7000 at the discretion of the investigator. RBP-7000 is a combination of the ATRIGEL Delivery System and risperidone. The ATRIGEL Delivery System allows for sustained-release of risperidone in a controlled manner.
PlaceboDRUGSubcutaneous injection of placebo using the ATRIGEL Delivery System on Days 1 and 29 in the lower quadrant of the abdomen rotating right and left on day 1 and 29.
RisperidoneDRUGOral risperidone 0.25 mg tablets daily for the first two days of the screening period. The two 0.25 mg tablets confirmed whether study participants had any negative reaction to risperidone prior to receiving a long-acting injection of risperidone (RBP-7000).

Frequently asked questions about RBP-7000

What is RBP-7000 used for?

RBP-7000 is an investigational small molecule developed for the treatment of schizophrenia. It has been studied in Phase 3 clinical development, including a long-term Phase 3 trial in subjects with schizophrenia. It is not described as approved, so it remains an investigational therapy in clinical development.

Who makes RBP-7000?

RBP-7000 is developed by Indivior Pharmaceuticals, Inc., which trades under the ticker INDV. The company has sponsored the clinical development program for RBP-7000 in schizophrenia, including Phase 1 and Phase 3 studies conducted in the United States.

What phase is RBP-7000 in?

RBP-7000 has reached Phase 3 clinical development for schizophrenia. The program includes a completed Phase 3 long-term study along with completed Phase 1 studies. All five trials in the program are listed as completed, with no active trials, so RBP-7000 remains an investigational drug rather than an approved product.

What clinical trials is RBP-7000 in?

RBP-7000 has been studied in five completed trials, including the Phase 3 long-term study NCT02203838 in schizophrenia, which enrolled 500 subjects. Earlier Phase 1 trials include NCT02768649, NCT02765555, and NCT02687984, which evaluated single ascending doses, first-in-man safety and pharmacokinetics, and different molecular weight polymer formulations.

How many patients were enrolled in RBP-7000 trials?

Across the five completed RBP-7000 trials, total enrollment was 955 subjects. The largest was the Phase 3 long-term study NCT02203838 with 500 subjects, followed by Phase 1 studies NCT02768649 with 45, NCT02687984 with 44, and NCT02765555 with 12 subjects, all in schizophrenia.

Were the RBP-7000 trials randomized and controlled?

Yes. The RBP-7000 clinical program used randomized, double-blind designs with active-controlled methodology. The trials enrolled adults aged 18 years and older of all sexes and were conducted in the United States. The program includes both Phase 1 studies and a Phase 3 long-term study in subjects with schizophrenia.
