Prochlorperazine

Findings Presented at the 2024 Psych Congress Include Data From More Than 300 Patients SAN DIEGO, Nov. 4, 2024 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) presented data from more than 300 patients diagnosed with tardive dyskinesia and treated with INGREZZA® (valbenazine) capsules. These data showed significant improvements in functional, social, emotional and health-related quality of life measures in Phase 3 and 4 studies and improvements in functional, social, independence, emotional and physical aspects of patients' lives and antipsychotic adherence in real-world practice. This research was shared at the 2024 Psych Congress in Boston. "Tardive dyskinesia can have a profound impact on patients that extends well beyond the physical symptoms caused by the movement disorder, affecting functional, social and emotional aspects of everyday life," said Eiry W. Roberts, M.D., Chief Medical Officer, Neurocrine Biosciences. "These data, taken together across clinical studies and real-world patient charts, are one of the largest efforts to examine and characterize the overall impact of treating tardive dyskinesia with INGREZZA and show significant improvements in measures that are important to patients and clinicians." Impact of INGREZZA on Function, Socialization and Emotionality in Phase 3 Studies This analysis (Poster #28) was conducted using combined data from 252 patients (n=71 placebo; n=181 INGREZZA) who completed the Phase 3 KINECT®-3 or KINECT®-4 studies. The 11-item Tardive Dyskinesia Impact Scale (TDIS), a validated patient-reported outcome measure, was used to evaluate tardive dyskinesia (TD) symptom impact at baseline through Week 48. TDIS scores range from 0 to 4 for each item, with higher scores indicating greater impact and decreases in scores indicating improvement. Results showed consistent improvements across all items, suggesting treatment with INGREZZA improved TDIS scores for both physical and socio-emotional domains. The most impacted items at baseline were self-consciousness (mean score: 1.99), embarrassment (1.89), mouth noises (1.80), unwanted attention (1.74) and writing (1.29). Improvements of 1 point or more from baseline to Week 48 were observed in self-consciousness (mean change -1.24), embarrassment (-1.19) and mouth noises (-1.05). Unwanted attention (-1.00) and writing (-0.78) also improved considerably. Impact of INGREZZA on Health-Related Quality of Life in Phase 4 Study This analysis (Poster #27) was conducted using data from 127 patients who participated in a double-blind, placebo-controlled, randomized withdrawal Phase 4 study. Following an 8-week treatment period, patients were randomly assigned INGREZZA or placebo for an additional 8 weeks. INGREZZA was then withdrawn for a 4-week washout period. Health-related quality of life (HRQOL) was measured using the EQ-5D-5L, which includes 5 dimensions of health status (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) each scored as: no problems (1); slight problems (2); moderate problems (3); severe problems (4); unable to/extreme problems (5). Lower scores indicate an improvement in health status. A utility index (UI), ranging from 0 to 1, and visual analog scale (VAS), ranging from 0 to 100, were also reported with higher scores indicating better health status. At the end of the treatment period (Week 16, n = 56), scores for each dimension and UI and VAS scores improved significantly, while scores returned to or were near baseline after the washout period (Week 20): Measure Baseline Score Week 16 Score Dimensions Mobility 1.91 1.57 Self-care 1.69 1.34 Usual activities 1.98 1.59 Pain/discomfort 2.15 1.70 Anxiety/depression 2.03 1.80 UI 0.68 0.80 VAS 73.82 79.57 Real-World Functional, Social, Independence, Emotional, Physical and Antipsychotic Adherence Improvements With INGREZZA A web-based survey and chart extraction (Poster #29) was conducted among U.S. physicians, nurse practitioners and physician assistants. Participants characterized the burden of diagnosed TD and improvement following at least two months of treatment with INGREZZA with at least one follow-up visit. This interim analysis included 78 clinicians caring for 164 patients. Most patients (82.9%) had mild to moderate TD severity, while 12.2% had severe TD. At the time of the survey, nearly all patients (93.9%) had experienced TD improvement after starting INGREZZA, irrespective of TD severity. TD had an impact on functional ability in 95.1% of patients, with the most commonly impacted areas being emotionality, socialization, activities of daily living and mouth/throat function. Among those impacted (n = 156), 94.2% improved in overall functional status. 87.8% of all patients experienced improvement in independence. For those with available information on antipsychotic adherence (n = 115), more than half (52.2%) experienced improved adherence.

Subsequent to the completion of the six-week placebo-controlled dosing, participants receiving INGREZZA continued on their current dose and placebo participants were randomized to receive either once-daily 40 mg or once-daily 80 mg of INGREZZA, through week 48 (42-week blinded treatment extension period; placebo participants randomized to 80 mg started on 40 mg for 1 week), followed by a four-week drug-free washout. Dose reduction to 40 mg was allowed for participants who were unable to tolerate the 80 mg dose. Patients were discontinued if the new dose was not tolerated. The study met its primary endpoint of change-from-baseline in AIMS at week six in the 80 mg once-daily dosing group compared to placebo as assessed by expert central blinded video raters. The mean change from baseline to week six in the AIMS rating was -3.2 for the 80 mg once-daily group as compared to -0.1 in the placebo group (P>0.0001). Sustained TD improvements were seen with INGREZZA 40 mg and 80 mg through week 48. INGREZZA was generally well tolerated throughout 48 weeks of treatment. The most common adverse reactions (≥ five percent and twice the rate of placebo) during the six-week double-blind, placebo-controlled phase was somnolence with the frequency of adverse events being similar among all treatment groups. Treatment-emergent adverse events (TEAEs) were consistent with those of prior studies. There were no drug-drug interactions identified in participants who were utilizing a wide range of psychotropic and other concomitant medications, and participants generally remained psychiatrically stable throughout the study. About the KINECT®-4 Phase 3 Study KINECT-4 is a Phase 3, open-label study, in which 163 participants with moderate to severe TD and underlying schizophrenia, schizoaffective disorder or mood disorder (including bipolar disorder or major depressive disorder) received 48 weeks of open-label treatment with once-daily INGREZZA (40 mg or 80 mg capsules) followed by a four-week washout. Dosing was initiated at 40 mg/day in all participants, with escalation to 80 mg/day at Week 4 based on effectiveness and tolerability. Dose reduction to 40 mg was allowed in participants who could not tolerate the 80 mg dose. Patients were discontinued if the new dose was not tolerated. Participants experienced TD improvements during long-term treatment as demonstrated by mean change from baseline to Week 48 in AIMS total score (sum of items 1-7, evaluated by site raters) with INGREZZA 40 mg/day (-10.2) or 80 mg/day (-11.0). Consistent with previous studies, INGREZZA was generally well tolerated. After Week 4, treatment emergent adverse events (TEAEs) that occurred in ≥5% of all participants (combined dose groups) were urinary tract infection (8.5%) and headache (5.2%). Changes from baseline in psychiatric stability, vital signs, electrocardiogram parameters and laboratory test values were generally small and not clinically significant. About Tardive Dyskinesia (TD) Tardive dyskinesia (TD) is a movement disorder that is characterized by uncontrollable, abnormal and repetitive movements of the face, torso and/or other body parts, which may be disruptive and negatively impact patients. The condition is associated with taking certain kinds of mental health medicines (antipsychotics) that help control dopamine receptors in the brain. Taking antipsychotics commonly prescribed to treat mental illnesses such as major depressive disorder, bipolar disorder, schizophrenia and schizoaffective disorder and other prescription medicines (metoclopramide and prochlorperazine) used to treat gastrointestinal disorders are associated with TD. In patients with TD, these treatments are thought to result in irregular dopamine signaling in a region of the brain that controls movement. The symptoms of TD can be severe and are often persistent and irreversible. TD is estimated to affect approximately 800,000 people in the U.S. About Chorea Associated with Huntington's Disease (HD) Huntington's disease (HD) is a hereditary progressive neurodegenerative disorder in which the loss of certain neurons within the brain causes motor, cognitive and psychiatric symptoms. Symptoms generally appear between the ages of 30 and 50 years and worsen over a 10- to 25-year period. Most people with HD experience chorea, an abnormal involuntary movement disorder, characterized by irregular and unpredictable movements. Chorea can affect various body parts and interfere with motor coordination, gait, swallowing and speech. HD is estimated to affect approximately 41,000 adults in the U.S., with more than 200,000 at risk of inheriting the disease. About INGREZZA® (valbenazine) Capsules and INGREZZA® SPRINKLE (valbenazine) Capsules INGREZZA is a selective vesicular monoamine transporter 2 (VMAT2) inhibitor approved by the U.S. Food and Drug Administration for the treatment of adults with tardive dyskinesia and the treatment of chorea associated with Huntington's disease (HD). Only INGREZZA offers a therapeutic dose from day one with no required titration. INGREZZA, developed by Neurocrine Biosciences, selectively inhibits VMAT2 with no appreciable binding affinity for VMAT1, dopaminergic (including D2), serotonergic, adrenergic, histaminergic or muscarinic receptors. While the specific way INGREZZA works to treat TD and HD chorea is not fully understood, INGREZZA is unique in that it selectively and specifically targets VMAT2 to inhibit the release of dopamine, a chemical in the brain that helps control movement. INGREZZA is believed to reduce extra dopamine signaling, which may lead to fewer uncontrollable movements. INGREZZA is always one capsule, once daily and can be taken together with most stable mental health regimens such as antipsychotics or antidepressants. Only INGREZZA offers the benefit of a sprinkle formulation, INGREZZA® SPRINKLE, for those who experience dysphagia, have difficulty swallowing or prefer not to swallow a pill. INGREZZA and INGREZZA SPRINKLE dosages approved for use are 40 mg, 60 mg and 80 mg capsules. Important Information Approved Uses INGREZZA® (valbenazine) capsules or INGREZZA® SPRINKLE (valbenazine) capsules are prescription medicines used to treat adults with: movements in the face, tongue, or other body parts that cannot be controlled (tardive dyskinesia). involuntary movements (chorea) of Huntington's disease. INGREZZA or INGREZZA SPRINKLE do not cure the cause of involuntary movements, and do not treat other symptoms of Huntington's disease, such as problems with thinking or emotions. It is not known if INGREZZA or INGREZZA SPRINKLE is safe and effective in children.

SAN DIEGO, Nov. 4, 2024 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) presented data from the long-term KINECT®-4 study demonstrating tardive dyskinesia remission in nearly 60% of participants at Week 48 with once-daily INGREZZA® (valbenazine) capsules treatment. This research, "Remission of Tardive Dyskinesia in Patients Receiving Long-Term Valbenazine Treatment" (Poster #98), was shared at the 2024 Psych Congress in Boston. "Tardive dyskinesia is persistent and irreversible, and effective treatment over time can have a positive impact for patients who are already living with underlying psychotic and mood disorders," said Eiry W. Roberts, M.D., Chief Medical Officer, Neurocrine Biosciences. "Our clinical studies have shown clinically meaningful and sustained improvement in tardive dyskinesia with INGREZZA, and these remission data add to the body of evidence characterizing the robust impact of INGREZZA treatment." This post hoc analysis was conducted using data from 103 participants who reached the final Week 48 visit in the open-label KINECT-4 clinical trial. Remission was defined as having a score of 1 or less (rating of "none" or "minimal") in each body region (items 1-7) on the Abnormal Involuntary Movement Scale (AIMS). Shifts to remission were defined as a maximum item score of 2 ("mild"), 3 ("moderate") or 4 ("severe") at baseline and each item score of 1 or less at Week 48. Treatment with INGREZZA resulted in tardive dyskinesia (TD) symptom remission for the majority of patients at Week 48: 59.2% (61/103) of participants had a score of 1 or less in each AIMS item. 65.0% (13/20) of participants in the 40 mg dose group and 57.8% (48/83) of participants in the 80 mg dose group met this remission threshold. 10% (10/103) of participants had complete resolution, with a total AIMS score of 0. Of the 4 participants with a maximum item score of 2 at baseline, 50.0% (2/4) reached the remission threshold. Of the 56 participants with a maximum item score of 3 at baseline, 64.3% (36/56) reached the remission threshold. Of the 43 participants with a maximum item score of 4 at baseline, 53.5% (23/43) reached the remission threshold. 65.0% (13/20) of participants in the 40 mg dose group and 57.8% (48/83) of participants in the 80 mg dose group met this remission threshold.
