RESUMO
PURPOSE/BACKGROUND: Zuranolone is a positive allosteric modulator of both synaptic and extrasynaptic γ-aminobutyric acid type A receptors and a neuroactive steroid approved as an oral, once-daily, 14-day treatment course for adults with postpartum depression in the United States. This study assessed zuranolone transfer into breast milk. METHODS/PROCEDURES: Healthy, nonpregnant, lactating adult female participants received once-daily 30 mg zuranolone from day (D)1 through D5 in this phase 1 open-label study. The relative infant dose (RID; weight-adjusted proportion of the maternal dose in breast milk over 24 hours) for 30 mg zuranolone was assessed at D5. An RID for 50 mg zuranolone was estimated using a simulation approach across a range of infant ages and weights. FINDINGS/RESULTS: Of 15 enrolled participants (mean age, 30.1 years), 14 completed the study. The mean RID for 30 mg zuranolone at D5 was 0.357%; the mean steady-state milk volume over D3 to D5 decreased from baseline by 8.3%. Overall unbound zuranolone in plasma was low (≤0.49%). Plasma concentrations peaked at D5 before decreasing in a biexponential manner. There was strong concordance between the temporal profiles of zuranolone concentrations in plasma and breast milk. The estimated mean RID for 50 mg zuranolone based on a milk intake of 200 mL/kg per day was 0.984%. All treatment-emergent adverse events reported by participants were mild, the most common being dizziness (n = 3). IMPLICATIONS/CONCLUSIONS: Zuranolone transfer into the breast milk of healthy, nonpregnant, lactating adult female participants was low; the estimated RID for 50 mg zuranolone was <1%, well below the <10% threshold generally considered compatible with breastfeeding.

BACKGROUND: Altered neurotransmission of γ-aminobutyric acid (GABA) has been implicated in the pathogenesis of depression. Whether SAGE-217, an oral, positive allosteric modulator of GABA type A receptors, is effective and safe for the treatment of major depressive disorder is unknown. METHODS: In this double-blind, phase 2 trial, we enrolled patients with major depression and randomly assigned them in a 1:1 ratio to receive 30 mg of SAGE-217 or placebo once daily. The primary end point was the change from baseline to day 15 in the score on the 17-item Hamilton Depression Rating Scale (HAM-D; scores range from 0 to 52, with higher scores indicating more severe depression). Secondary efficacy end points, which were assessed on days 2 through 8 and on days 15, 21, 28, 35, and 42, included changes from baseline in scores on additional depression and anxiety scales, a reduction from baseline of more than 50% in the HAM-D score, a HAM-D score of 7 or lower, and a Clinical Global Impression of Improvement score of 1 (very much improved) or 2 (much improved) (on a scale of 1 to 7, with a score of 7 indicating that symptoms are very much worse). RESULTS: A total of 89 patients underwent randomization: 45 patients were assigned to the SAGE-217 group, and 44 to the placebo group. The mean baseline HAM-D score was 25.2 in the SAGE-217 group and 25.7 in the placebo group. The least-squares mean (±SE) change in the HAM-D score from baseline to day 15 was -17.4±1.3 points in the SAGE-217 group and -10.3±1.3 points in the placebo group (least-squares mean difference in change, -7.0 points; 95% confidence interval, -10.2 to -3.9; P<0.001). The differences in secondary end points were generally in the same direction as those of the primary end point. There were no serious adverse events. The most common adverse events in the SAGE-217 group were headache, dizziness, nausea, and somnolence. CONCLUSIONS: Administration of SAGE-217 daily for 14 days resulted in a reduction in depressive symptoms at day 15. Adverse events were more common in the SAGE-217 group than in the placebo group. Further trials are needed to determine the durability and safety of SAGE-217 in major depressive disorder and to compare SAGE-217 with available treatments.

Major depressive disorder (MDD) is a mental health disorder that can cause disability and functional impairment that standard-of-care (SOC) antidepressant therapies (ADTs) can take weeks to treat. Zuranolone is a neuroactive steroid and positive allosteric modulator of synaptic and extrasynaptic γ-aminobutyric acid (GABA) type A receptors approved as an oral, once-daily, 14-day treatment course in adults with postpartum depression and under investigation in adults with MDD. The phase 3 CORAL Study (NCT04476030) evaluated the efficacy and safety of zuranolone 50 mg co-initiated with SOC ADT (zuranolone+ADT) vs placebo co-initiated with SOC ADT (placebo+ADT) in adults with MDD. Patients were randomized 1:1 to once-daily, blinded zuranolone+ADT or placebo+ADT for 14 days, then continued open-label SOC ADT for 28 more days. The primary endpoint was change from baseline (CFB) in the 17-item Hamilton Rating Scale for Depression (HAMD-17) total score at Day 3. Among 425 patients in the full analysis set, CFB in HAMD-17 total score at Day 3 was significantly improved with zuranolone+ADT vs placebo+ADT (least squares mean [standard error], -8.9 [0.39] vs -7.0 [0.38]; p = 0.0004). The majority of patients receiving zuranolone+ADT that experienced treatment-emergent adverse events (TEAEs) reported mild or moderate events. The most common TEAEs present in ≥10% of patients in either zuranolone+ADT or placebo+ADT groups were somnolence, dizziness, headache, and nausea. These results demonstrate that zuranolone+ADT provided more rapid improvement in depressive symptoms compared with placebo+ADT in patients with MDD, with a safety profile consistent with previous studies.

BACKGROUND: Despite the overall high degree of response to pharmacotherapy, consensus is lacking on how to judge clinical response or define optimal treatment/remission when treating adults with attention-deficit/hyperactivity disorder (ADHD). This study examined clinical response and symptomatic remission in analyses of 2 studies of lisdexamfetamine dimesylate (LDX) in adults with ADHD. METHODS: In a 4-week, double-blind, forced-dose trial, adults with ADHD were randomized to LDX 30, 50, and 70 mg/day (mg/d) or placebo. In a second, open-label, follow-up trial, adults entering from the 4-week study were titrated to an "optimal" LDX dose (30 mg/d [n=44], 50 mg/d [n=112], and 70 mg/d [n=171]) over 4 weeks, and maintained for 11 additional months. The ADHD Rating Scale IV (ADHD-RS-IV) with adult prompts and the Clinical Global Impressions-Improvement (CGI-I) scale assessed efficacy. Clinical response was defined, post hoc, as ≥30% reduction from baseline in ADHD-RS-IV and CGI-I rating of 1 or 2; symptomatic remission was defined as ADHD-RS-IV total score ≤18. Log rank analysis examined overall significance among the treatment groups in time to response or remission. RESULTS: Four hundred and fourteen participants in the 4-week study and 345 in the open-label, extension study were included in the efficacy populations. All LDX groups improved by ADHD-RS-IV and CGI-I scores in both studies. In the 4-week study (n=414), 69.3% responded and 45.5% achieved remission with LDX (all doses); 37.1% responded and 16.1% achieved remission with placebo; time (95% CI) to median clinical response (all LDX doses) was 15.0 (15.0, 17.0) days and to remission was 31.0 (28.0, 37.0) days (P<.0001 overall). In the open-label study, with LDX (all doses), 313 (95.7%) and 278 (85.0%) of 327 participants with evaluable maintenance-phase data met criteria for response and remission, respectively. Of participants who completed dose optimization, 75.2% remained responders and 65.7% remained in remission in the 12-month study. Overall, 285 (82.6%) and 227 (65.8%) of 345 participants were responders and remitters, respectively, at their final visits. CONCLUSION: In the long-term study, with open-label, dose-optimized LDX treatment, most adults with ADHD achieved clinical response and/or symptomatic remission; almost two-thirds maintained symptomatic remission over the remaining 11 months.

Objective: To evaluate the efficacy and safety of zuranolone, an investigational neuroactive steroid and GABAA receptor positive allosteric modulator, in major depressive disorder (MDD).Methods: The phase 3, double-blind, randomized, placebo-controlled MOUNTAIN study enrolled adult outpatients with DSM-5-diagnosed MDD, 17-item Hamilton Depression Rating Scale total score (HDRS-17) ≥ 22, and Montgomery-Asberg Depression Rating Scale total score ≥ 32. Patients were randomized to treatment with zuranolone 20 mg, zuranolone 30 mg, or placebo for 14 days, followed by an observation period (days 15-42) and an extended follow-up (days 43-182). The primary endpoint was change from baseline (CFB) in HDRS-17 at day 15.Results: 581 patients were randomized to receive zuranolone (20 mg, n = 194; 30 mg, n = 194) or placebo (n = 193). Day 15 HDRS-17 least-squares mean (LSM) CFB was -12.5 (zuranolone 30 mg) vs -11.1 (placebo; P = .116). Improvement vs placebo was significant at days 3, 8, and 12 (all P < .05). LSM CFB (zuranolone 20 mg vs placebo) was not significant at any measured time point. Post hoc analyses of zuranolone 30 mg in patients with measurable plasma zuranolone concentration and/or severe disease (baseline HDRS-17 ≥ 24) showed significant improvement vs placebo at days 3, 8, 12, and 15 (all P < .05). Incidence of treatment-emergent adverse events was similar between zuranolone and placebo groups; the most common (≥ 5%) were fatigue, somnolence, headache, dizziness, diarrhea, sedation, and nausea.Conclusions: MOUNTAIN did not meet its primary endpoint. Significant rapid improvements in depressive symptoms were observed with zuranolone 30 mg at days 3, 8, and 12. Zuranolone was generally well tolerated in patients with MDD.Trial Registration: ClinicalTrials.gov identifier: NCT03672175.

Objective: Concurrent anxiety and/or insomnia symptoms in women with postpartum depression (PPD) are common and associated with more severe PPD. The effects of zuranolone on concurrent anxiety and/or insomnia symptoms and on patient-perceived functional health in women with PPD in the ROBIN study are reported.Methods: The phase 3, double-blind, randomized, placebo-controlled trial (conducted January 2017-December 2018) included women aged 18-45 years, ≤ 6 months postpartum, with PPD (onset of DSM-5-defined major depressive episode in the third trimester or ≤ 4 weeks postpartum) and baseline 17-item Hamilton Depression Rating Scale (HDRS-17) total score ≥ 26. Women were randomized 1:1 to once-daily oral zuranolone 30 mg (n = 77) or placebo (n = 76) for 14 days with follow-up through day 45. Concurrent remission of depressive and anxiety symptoms (Hamilton Anxiety Rating Scale total score ≤ 7 plus HDRS-17 total score ≤ 7 or Montgomery-Asberg Depression Rating Scale total score ≤ 10), improvement in insomnia symptoms, patient-perceived functional health, and treatment effect sizes described by number needed to treat (NNT) were assessed. Analyses were exploratory; P values are nominal.Results: Rates of concurrent remission of depressive and anxiety symptoms were higher with zuranolone versus placebo (P < .05) at days 3, 15, and 45; the rate of sustained concurrent remission (ie, at both days 15 and 45) was also higher with zuranolone (P < .05). Anxiety symptoms (assessed by HDRS-17 anxiety/somatization subscale and Edinburgh Postnatal Depression Scale anxiety subscale) improved with zuranolone versus placebo (P < .05) at days 3 through 45. Potential benefits on insomnia symptoms and patient-perceived functional health were observed. Day 15 NNTs were 5 for both HDRS-17 response and remission.Conclusions: Zuranolone was associated with concurrent improvements in depressive and anxiety symptoms, with beneficial effects on insomnia symptoms and patient-perceived functional health in adults with PPD.Trial Registration: ClinicalTrials.gov identifier: NCT02978326.

OBJECTIVE: This study assessed the efficacy and safety of a 14-day treatment course of once-daily zuranolone 50 mg, an investigational oral positive allosteric modulator of the γ-aminobutyric acid type A (GABAA) receptor, for the treatment of major depressive disorder. METHODS: Patients 18-64 years of age with severe major depressive disorder were enrolled in this randomized, double-blind, placebo-controlled trial. Patients self-administered zuranolone 50 mg or placebo once daily for 14 days. The primary endpoint was change from baseline in total score on the 17-item Hamilton Depression Rating Scale (HAM-D) at day 15. Safety and tolerability were assessed by incidence of adverse events. RESULTS: Of 543 randomized patients, 534 (266 in the zuranolone group, 268 in the placebo group) constituted the full analysis set. Compared with patients in the placebo group, patients in the zuranolone group demonstrated a statistically significant improvement in depressive symptoms at day 15 (least squares mean change from baseline HAM-D score, -14.1 vs. -12.3). Numerically greater improvements in depressive symptoms for zuranolone versus placebo were observed by day 3 (least squares mean change from baseline HAM-D score, -9.8 vs. -6.8), which were sustained at all visits throughout the treatment and follow-up periods of the study (through day 42, with the difference remaining nominally significant through day 12). Two patients in each group experienced a serious adverse event; nine patients in the zuranolone group and four in the placebo group discontinued treatment due to adverse events. CONCLUSIONS: Zuranolone at 50 mg/day elicited a significantly greater improvement in depressive symptoms at day 15, with a rapid time to effect (day 3). Zuranolone was generally well tolerated, with no new safety findings compared with previously studied lower dosages. These findings support the potential of zuranolone in treating adults with major depressive disorder.

BACKGROUND: Brexanolone is currently the only treatment specifically approved for postpartum depression (PPD) in the United States, based on the results from one Phase 2 and two Phase 3 double-blind, randomized, controlled trials in the HUMMINGBIRD program. METHODS: Adults with PPD randomized to a 60-h infusion of brexanolone 90 µg/kg/h (BRX90) or placebo from the 3 trials were included in these post hoc analyses. Data on change from baseline (CFB) in the 17-item Hamilton Rating Scale for Depression (HAMD-17) total score, HAMD-17 Anxiety/Somatization and Insomnia subscales, and Clinical Global Impression of Improvement (CGI-I) scale were pooled. Response rates for HAMD-17 (≥50 % reduction from baseline) and CGI-I (score of 1 or 2) scales and time to response were analyzed. RESULTS: Patients receiving BRX90 (n = 102) versus placebo (n = 107) achieved a more rapid HAMD-17 response (median, 24 vs 36 h; p = 0.0265), with an Hour-60 cumulative response rate of 81.4 % versus 67.3 %; results were similar for time to CGI-I response (median, 24 vs 36 h; p = 0.0058), with an Hour-60 cumulative response rate of 81.4 % versus 61.7 %. CFB in HAMD-17 Anxiety/Somatization and Insomnia subscales also favored BRX90 versus placebo, starting at Hour 24 through Day 30 (all p < 0.05), and response rates for both subscales were higher with BRX90. LIMITATIONS: The study was not powered to assess exploratory outcomes. CONCLUSIONS: Brexanolone was associated with rapid improvement in depressive symptoms and symptoms of anxiety and insomnia compared with placebo in women with PPD. These data continue to support the use of brexanolone to treat adults with PPD.

OBJECTIVE: Postpartum depression (PPD) is a common perinatal complication with adverse maternal and infant outcomes. This study investigated the efficacy and safety of zuranolone, a positive allosteric modulator of synaptic and extrasynaptic GABAA receptors and neuroactive steroid, as an oral, once-daily, 14-day treatment course for patients with severe PPD. METHODS: In this double-blind phase 3 trial, women with severe PPD were randomized in a 1:1 ratio to receive zuranolone 50 mg/day or placebo for 14 days. The primary endpoint was change from baseline in total score on the 17-item Hamilton Depression Rating Scale (HAM-D) at day 15; key secondary endpoints were change from baseline in HAM-D score at days 3, 28, and 45 and change from baseline in Clinical Global Impressions severity (CGI-S) score at day 15. Adverse events were monitored. RESULTS: Among 196 patients randomized (zuranolone, N=98; placebo, N=98), 170 (86.7%) completed the 45-day study. Treatment with zuranolone compared with placebo resulted in statistically significant improvement in depressive symptoms at day 15 (least squares mean [LSM] change from baseline in HAM-D score, -15.6 vs. -11.6; LSM difference, -4.0, 95% CI=-6.3, -1.7); significant improvement in depressive symptoms was also reported at days 3, 28, and 45. CGI-S score at day 15 significantly improved with zuranolone compared with placebo. The most common adverse events (≥10%) with zuranolone were somnolence, dizziness, and sedation. No loss of consciousness, withdrawal symptoms, or increased suicidal ideation or behavior were observed. CONCLUSIONS: In this trial, zuranolone demonstrated significant improvements in depressive symptoms and was generally well tolerated, supporting the potential of zuranolone as a novel, rapid-acting oral treatment for PPD.

Objective: Zuranolone is a positive allosteric modulator of both synaptic and extrasynaptic γ-aminobutyric acid (GABA) type A receptors and a neuroactive steroid approved in the United States as an oral, once-daily, 14-day treatment course for adults with postpartum depression and under investigation for adults with major depressive disorder (MDD). Interim results from the open-label, longitudinal, phase 3 SHORELINE Study (NCT03864614) that evaluated the long-term safety and efficacy of zuranolone in adults with MDD are reported.Methods: This interim report includes patients who were enrolled and had the opportunity to be on study for up to 1 year between February 2019 and September 2021. Adults aged 18-75 years with MDD diagnosed per DSM-5 criteria and a 17-item Hamilton Rating Scale for Depression (HAMD-17) total score ≥ 20 received an initial 30-mg or 50-mg 14-day zuranolone course. HAMD-17 responders (≥ 50% reduction from baseline) at Day (D)15 of the initial treatment period were allowed to continue in the study beyond D28 and were followed up for ≤ 1 year, during which repeat treatment courses were permitted. The primary endpoint was safety and tolerability of the initial and repeat treatment courses through 1 year. Secondary endpoints included change from baseline (CFB) in HAMD-17 total score and need for repeat treatment course(s).Results: As of September 2021, among patients in the 30-mg (n = 725) and 50-mg (n = 199) Cohorts who received a zuranolone dose, 493 (68.0%) and 137 (68.8%), respectively, reported a treatment-emergent adverse event (TEAE); most patients who experienced TEAEs reported mild/moderate events (30-mg Cohort, 90.9% [448/493]; 50-mg Cohort, 85.4% [117/137]). Mean (standard deviation) CFB HAMD-17 total score at D15 of the initial treatment period was -15.2 (7.1) and -16.0 (6.0) for the 30-mg and 50-mg Cohorts, respectively; similar improvements were observed after repeat treatment courses. The proportion of patients who received only 1 treatment course during their time on study was 42.9% (210/489) in the 30-mg Cohort and 54.8% (80/146) in the 50-mg Cohort; 57.1% (279/489) and 45.2% (66/146) patients, respectively, received 2-5 total treatment courses. The majority of patients who initially responded to zuranolone received ≤ 2 total treatment courses (30-mg Cohort, 68.5% [335/489]; 50-mg Cohort, 79.5% [116/146]).Conclusions: Of patients who experienced TEAEs, most reported mild or moderately severe events, and responders to zuranolone experienced improvements in depressive symptoms with initial and repeat treatment courses.Trial Registration: ClinicalTrials.gov identifier: NCT03864614.

BACKGROUND: The purpose of this study was to expand the understanding of the burden of illness experienced by adults with Attention Deficit-Hyperactivity Disorder (ADHD) living in different countries and treated through different health care systems. METHODS: Fourteen focus groups and five telephone interviews were conducted in seven countries in North America and Europe, comprised of adults who had received a diagnosis of ADHD. The countries included Canada, France, Germany, Italy, The Netherlands, United Kingdom, and United States (two focus groups in each country). There were 108 participants. The focus groups were designed to elicit narratives of the experience of ADHD in key domains of symptoms, daily life, and social relationships. Consonant with grounded theory, the transcripts were analyzed using descriptive coding and then themed into larger domains. RESULTS: Participants' statements regarding the presentation of symptoms, childhood experience, impact of ADHD across the life course, addictive and risk-taking behavior, work and productivity, finances, relationships and psychological health impacts were similarly themed across all seven countries. These similarities were expressed through the domains of symptom presentation, childhood experience, medication treatment issues, impacts in adult life and across the life cycle, addictive and risk-taking behavior, work and productivity, finances, psychological and social impacts. CONCLUSIONS: These data suggest that symptoms associated with adult ADHD affect individuals similarly in different countries and that the relevance of the diagnostic category for adults is not necessarily limited to certain countries and sociocultural milieus.

BACKGROUND: Major depressive disorder (MDD), a disabling, potentially life-threatening condition, negatively affects health-related quality of life (HRQoL). This secondary analysis aimed to understand the impact of the neuroactive steroid zuranolone on HRQoL using the Short Form-36v2 Health Survey (SF-36v2). METHODS: Adult patients with MDD and 17-item Hamilton Rating Scale for Depression total score ≥22 were randomized 1:1 to receive zuranolone 30 mg or placebo for 2 weeks, with 4 weeks follow-up. SF-36v2 scores were assessed at Day 15 across 8 domains (Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional, and Mental Health) and 2 summary scores (Physical and Mental Component), using a mixed-effects model for repeated measures. Correlations between SF-36v2 scores and clinician-reported efficacy endpoints were assessed using Pearson's correlation. RESULTS: Eighty-nine patients were treated with zuranolone 30 mg (n = 45) or placebo (n = 44). In zuranolone-treated patients, HRQoL improved across all SF-36v2 domains and summary scores at Day 15. Improvements exceeding established minimally important difference thresholds were observed in Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional, and Mental Health scores. Improvements in General Health, Vitality, Mental Health, and Mental Component Summary were statistically significant versus placebo (p ≤ 0.025). Clinician-rated endpoints negatively correlated with SF-36v2 scores. LIMITATIONS: The small unipolar depression sample may not be representative of all US MDD patients. HRQoL measures could be impacted by factors unrelated to depression. CONCLUSIONS: Zuranolone-treated patients reported rapid and significant improvements in HRQoL versus placebo at Day 15. HRQoL improvements correlated with improvements in clinician-rated assessments. TRIAL REGISTRATION: clinicaltrials.gov:NCT03000530; https://clinicaltrials.gov/ct2/show/NCT03000530.

Importance: Postpartum depression (PPD) is one of the most common medical complications during and after pregnancy, negatively affecting both mother and child. Objective: To demonstrate the efficacy and safety of zuranolone, a neuroactive steroid γ-aminobutyric acid receptor-positive allosteric modulator, in PPD. Design, Setting, and Participants: This phase 3, double-blind, randomized, outpatient, placebo-controlled clinical trial was conducted between January 2017 and December 2018 in 27 enrolling US sites. Participant were women aged 18 to 45 years, 6 months or fewer post partum, with PPD (major depressive episode beginning third trimester or ≤4 weeks postdelivery), and baseline 17-item Hamilton Rating Scale for Depression (HAMD-17) score of 26 or higher. Analysis was intention to treat and began December 2018 and ended March 2019. Interventions: Randomization 1:1 to placebo:zuranolone, 30 mg, administered orally each evening for 2 weeks. Main Outcomes and Measures: Primary end point was change from baseline in HAMD-17 score for zuranolone vs placebo at day 15. Secondary end points included changes from baseline in HAMD-17 total score at other time points, HAMD-17 response (≥50% score reduction) and remission (score ≤7) rates, Montgomery-Åsberg Depression Rating Scale score, and Hamilton Rating Scale for Anxiety score. Safety was assessed by adverse events and clinical assessments. Results: Of 153 randomized patients, the efficacy set comprised 150 patients (mean [SD] age, 28.3 [5.4] years), and 148 (98.7%) completed treatment. A total of 76 patients were randomized to placebo, and 77 were randomized to zuranolone, 30 mg. Zuranolone demonstrated significant day 15 HAMD-17 score improvements from baseline vs placebo (-17.8 vs -13.6; difference, -4.2; 95% CI, -6.9 to -1.5; P = .003). Sustained differences in HAMD-17 scores favoring zuranolone were observed from day 3 (difference, -2.7; 95% CI, -5.1 to -0.3; P = .03) through day 45 (difference, -4.1; 95% CI, -6.7 to -1.4; P = .003). Sustained differences at day 15 favoring zuranolone were observed in HAMD-17 response (odds ratio, 2.63; 95% CI, 1.34-5.16; P = .005), HAMD-17 score remission (odds ratio, 2.53; 95% CI, 1.24-5.17; P = .01), change from baseline for Montgomery-Åsberg Depression Rating Scale score (difference, -4.6; 95% CI, -8.3 to -0.8; P = .02), and Hamilton Rating Scale for Anxiety score (difference, -3.9; 95% CI, -6.7 to -1.1; P = .006). One patient per group experienced a serious adverse event (confusional state in the zuranolone group and pancreatitis in the placebo group). One patient in the zuranolone group discontinued because of an adverse event vs none for placebo. Conclusions and Relevance: In this randomized clinical trial, zuranolone improved the core symptoms of depression as measured by HAMD-17 scores in women with PPD and was generally well tolerated, supporting further development of zuranolone in the treatment of PPD.

RESUMO
Although the concept of remission has been widely accepted and utilized in depression and anxiety disorders, there has been much less emphasis on defining remission in schizophrenia. Recently, an expert consensus definition of remission in schizophrenia was proposed along specific operational criteria for the attainment of remission focusing on the three core dimensions of psychopathology identified within schizophrenia: psychoticism, disorganization and negative symptoms. To date, the criteria have been applied retrospectively to several clinical studies, and these have demonstrated that the proposed definition of remission correlates significantly with established measures of symptom severity, functioning and quality of life, and appears achievable for a significant proportion of patients receiving at least 3 months of pharmacotherapy. In this article we extend the notion of remission to include an examination of the possible association of several modifiable and unmodifiable factors and co-morbidities on remission status. We also propose an investigation into the likelihood of different patient populations in achieving remission as well as assessing the impact of remission on health care costs and family burden. Since cognitive dysfunction and negative symptoms may be strongly correlated with a lower likelihood of achieving remission, we recommend retrospective and/or prospective studies to determine the relationship between neurocognitive status and the predominance of negative symptoms at treatment start and the probability of achieving remission. Taken together, these studies should help identify key predictors of remission, further define the remitted state, reduce therapeutic pessimism, raise treatment expectations and chart a strategy for further research in this important area.

This analysis characterizes patients with schizophrenia or schizoaffective disorder treated with risperidone who met remission criteria. In a 50-week, open-label trial, stable patients received long-acting injectable risperidone every 2 weeks. Remission criteria included severity (absent-mild ratings on core symptoms of the Positive and Negative Syndrome Scale) and duration (> or =6 months) components. The patients not remitted (severity component only) at baseline (n=394) are the subjects of this report. Measures applied included the PANSS, Clinical Global Impressions-Severity, patient-rated mental health status (Short Form-36), and Drug Attitude Inventory. Among patients who met remission criteria during the study (n=82), mean scores for all 30 PANSS items reflected absent-mild ratings at endpoint. The highest items represented an 'interpersonal' cluster, although mean ratings were still minimal to mild. Remitted patients experienced substantial improvements in Short Form-36 and Drug Attitude Inventory scores at endpoint. Although improvement occurred, it was less robust in patients who remained nonremitted (n=312). Logistic regression analysis found that remission (severity component only) was associated with a 97.1% probability of a 'not ill' rating on the Clinical Global Impressions-Severity. These remission criteria identified patients who differed from the nonremitted population on symptoms of psychopathology, medication attitude, health status, and overall clinical status, supporting the clinical validity of the remission criteria.

BACKGROUND: Several clinical studies have established the efficacy, safety, and tolerability of long-acting risperidone administered once every 2 weeks in patients with schizophrenia or schizoaffective disorder. This report evaluates preliminary efficacy, safety, tolerability, and pharmacokinetic data for a novel (once-monthly) administration of long-acting injectable risperidone 50 mg in patients with schizophrenia or schizoaffective disorder. METHODS: Clinically stable patients participated in a 1-year, open-label, single-arm, multicenter pilot study. During the 4-week lead-in phase, patients received long-acting risperidone 50 mg injections every 2 weeks, with 2 weeks of oral risperidone supplementation. Injections of long-acting risperidone 50 mg every 4 weeks followed for up to 48 weeks, without oral supplementation. The primary endpoint was relapse; other assessments included PANSS, CGI-S, adverse event reports, and determination of risperidone and 9-hydroxyrisperidone plasma concentrations. RESULTS: Twelve patients in the intent-to-treat population (n = 67) met relapse criteria (17.9%). Relapse risk at 1 year was estimated as 22.4%. Non-statistically significant improvements in symptoms (PANSS) and clinical status (CGI-S) at endpoint were observed. The most common adverse events included schizophrenia aggravated not otherwise specified (19.5%), anxiety (16.1%), insomnia (16.1%), and headache (11.5%). There were no unexpected safety and tolerability findings. Mean plasma concentrations for risperidone and 9-hydroxyrisperidone were generally stable during the study. CONCLUSION: Once-monthly dosing of long-acting risperidone was well tolerated, associated with a relatively low relapse rate (similar to that reported with other antipsychotics), and maintained the clinically stable baseline status of most patients. Although the results suggest that some symptomatically stable patients with schizophrenia or schizoaffective disorder might be safely managed with long-acting risperidone 50 mg once monthly, these findings alone do not identify which patients will have a sufficient therapeutic benefit nor do they quantify comparative effects of standard and altered dosing. Study limitations (the open-label pilot study design, small sample size, and lack of a concurrent biweekly treatment arm) prevent broad interpretations and extrapolations of results. Controlled studies would be required to support a recommendation for alternative dosing regimens.
RESUMO
OBJECTIVE: To describe symptom rebound in children with ADHD treated with lisdexamfetamine dimesylate (LDX) or placebo. METHOD: During a 4-week, randomized, double-blind, placebo-controlled trial of LDX, parents/caregivers completed the Conners' Parent Rating Scale-Revised: Short Form symptom rating scale throughout the day. Response, rebound, and emotional lability (EL) were assessed post hoc based on predefined criteria. RESULTS: Most participants given LDX ( n = 207) were responders throughout the day (50.7%-55.6%) versus placebo ( n = 72; 11.1%-22.2%). A total of seven (3.4%) LDX participants showed rebound in the afternoon and/or evening versus seven (9.7%) with placebo. In both groups, most incidences of rebound occurred in the evening. EL (mean) was higher in LDX rebounders and nonresponders (range = 4.2-9.0) versus LDX responders (range = 1.3-1.6) and versus placebo rebounders (range = 0.7-1.9). CONCLUSION: ADHD symptom rebound occurred in few participants (3.3%) given LDX (accompanied by clinically significant EL). Overall, more participants given LDX versus placebo responded throughout the day.

BACKGROUND: Gantenerumab is a fully human monoclonal antibody that binds aggregated amyloid-ß (Aß) and removes Aß plaques by Fc receptor-mediated phagocytosis. In the SCarlet RoAD trial, we assessed the efficacy and safety of gantenerumab in prodromal Alzheimer's disease (AD). METHODS: In this randomized, double-blind, placebo-controlled phase III study, we investigated gantenerumab over 2 years. Patients were randomized to gantenerumab 105 mg or 225 mg or placebo every 4 weeks by subcutaneous injection. The primary endpoint was the change from baseline to week 104 in Clinical Dementia Rating Sum of Boxes (CDR-SB) score. We evaluated treatment effects on cerebrospinal fluid biomarkers (all patients) and amyloid positron emission tomography (substudy). A futility analysis was performed once 50% of patients completed 2 years of treatment. Safety was assessed in patients who received at least one dose. RESULTS: Of the 3089 patients screened, 797 were randomized. The study was halted early for futility; dosing was discontinued; and the study was unblinded. No differences between groups in the primary (least squares mean [95% CI] CDR-SB change from baseline 1.60 [1.28, 1.91], 1.69 [1.37, 2.01], and 1.73 [1.42, 2.04] for placebo, gantenerumab 105 mg, and gantenerumab 225 mg, respectively) or secondary clinical endpoints were observed. The incidence of generally asymptomatic amyloid-related imaging abnormalities increased in a dose- and APOE ε4 genotype-dependent manner. Exploratory analyses suggested a dose-dependent drug effect on clinical and biomarker endpoints. CONCLUSIONS: The study was stopped early for futility, but dose-dependent effects observed in exploratory analyses on select clinical and biomarker endpoints suggest that higher dosing with gantenerumab may be necessary to achieve clinical efficacy.

Approximately one-third of persons with depression do not respond to antidepressant monotherapy. Studies suggest that atypical antipsychotic augmentation may benefit these patients. We investigated the longer-term efficacy of risperidone augmentation of serotonin-selective reuptake inhibitor treatment for resistant depression. In 57 in- and outpatient centers in three countries, we conducted a three-phase study with 4-6 weeks of open-label citalopram monotherapy, 4-6 weeks of open-label risperidone augmentation, and a 24-week double-blind, placebo-controlled discontinuation phase. A total of 489 patients with major depressive disorder and 1-3 documented treatment failures entered the citalopram monotherapy phase (20-60 mg/day). Patients with <50% reduction in HAM-D-17 scores entered the risperidone augmentation phase (0.25-2.0 mg/day). Patients with HAM-D-17< or =7 or CGI-S < or = 2 were randomized to risperidone or placebo augmentation. The primary outcome was time to relapse during the double-blind phase. During citalopram monotherapy, 434 patients had <50% HAM-D-17 reduction; 299 (68.9%) were fully nonresponsive (<25% reduction) and 135 were partially nonresponsive (25-49% reduction). Of the 386 nonresponders who entered the augmentation phase, 243 remitted and 241 entered the double-blind phase. Median time to relapse was 102 days with risperidone augmentation and 85 days with placebo (NS); relapse rates were 53.3 and 54.6%, respectively. In a post hoc analysis of patients fully nonresponsive to citalopram monotherapy, median time to relapse was 97 days with risperidone augmentation and 56 with placebo (p = 0.05); relapse rates were 56.1 and 64.1%, respectively (p < or = 0.05). Open-label risperidone augmentation substantially enhanced response in treatment-resistant patients, but the longer-term benefits of augmentation were not demonstrated in this study.
