Effects of Long-Term Sertraline Use on Pediatric Growth and Development: The Sertraline Pediatric Registry for The Evaluation of Safety (SPRITES).

Objective: To describe the results of the Sertraline Pediatric Registry for The Evaluation of Safety (SPRITES) outcome measures of cognitive, emotional, and physical development following long-term treatment with sertraline (for up to 3 years) in children and adolescents aged 6-16 years. Methods: SPRITES was a long-term, multicenter, open-label, prospective observational study designed to compare physical and psychological development in pediatric patients exposed to sertraline (with or without psychotherapy) or psychotherapy alone in usual care settings. Data were summarized descriptively, and outcomes were evaluated using a marginal structural model. Results: Between April 2012 and September 2020, 941 patients across 44 U.S. sites participated in the study. At baseline, 695 participants were exposed to sertraline (physician prescribed) with or without psychotherapy, and 245 participants were exposed to psychotherapy alone. Of these, 432 participants (46.0%) completed the full 3-year study follow-up. No significant changes across time were found in standardized height, BRIEF (Behavior Rating Inventory of Executive Function), Trails B, and Tanner stage based on cumulative sertraline exposure or exposure since the last visit. Change in mean standardized weight across time was positively associated with both cumulative sertraline exposure (p = 0.02) and exposure since the last visit (p = 0.029). The mean changes from baseline across time in standardized weight were standard deviations of 0.02, 0.03, 0.16, and 0.17 at months 3, 6, 30, and 36, respectively. However, this finding was not observed in the mean change across time in standardized body mass index, which was not statistically significant. Conclusions: Results are consistent with normal development. Although a statistically significant finding for standardized weight was observed in comparative analyses, the magnitude of the change is small and observed at higher doses of sertraline only. No other significant differences were observed between the "sertraline" group and the "no pharmacological therapy" group on other primary outcome measures.

Incidence of safety events after immune checkpoint inhibitor initiation for advanced-stage non-small-cell lung cancer: a real-world study.

Aim: To describe the incidence of safety events after immune checkpoint inhibitor (ICI) initiation for advanced-stage non-small-cell lung cancer. Methods: Retrospective cohort study using the HealthCore Integrated Research Database in the USA to examine the incidence of prespecified safety events of interest after ICI initiation (n = 5278). Results: The most common safety events after ICI initiation included malaise/fatigue (incidence rate [IR]: 70.7 per 100 person-years; 95% CI: 66.5-75.1) and nausea/vomiting (IR: 32.4; 30.0-34.8). Other potential immune-mediated events, including colitis (IR: 7.11; 6.26-8.04) and pneumonitis (IR: 5.47; 4.76-6.25), were less frequent but higher than after any systemic anti-cancer therapy. No safety event rate substantially increased 6 months after ICI initiation. Conclusion: This large real-world study reports the incidence of safety events with ICI regimens for advanced-stage non-small-cell lung cancer.

Researchers wanted to investigate side effects identified with advanced lung cancer during treatment, particularly immunotherapy. To investigate these side effects, researchers examined health insurance claims records from patients who were diagnosed with advanced lung cancer between January 2010 and July 2019, and who received treatment at various clinics across the USA. Researchers identified records for 44,045 patients treated for advanced lung cancer, with 5278 being treated with immunotherapy. After patients started immunotherapy, the most commonly reported side effects were tiredness and nausea/vomiting. Other side effects possibly related to immunotherapy were inflammation of the large intestine and lung inflammation ­ these events were not reported very often and did not increase in frequency 6 months after start of treatment. This large real-world study provides estimates for the frequency of side effects for those treated for advanced lung cancer, and finds that there were no large increases in the occurrence of any particular side effect in the 6 months after patients started immunotherapy for advanced lung cancer.

Health care resource utilization and costs associated with advanced or metastatic nonsmall cell lung cancer in the United States.

BACKGROUND: The treatment landscape for advanced nonsmall cell lung cancer (NSCLC) has evolved from 2015 onward, since the introduction of immune checkpoint inhibitors (ICIs). Considering this shift, there have been limited prior analyses that assess the economic burden of NSCLC within the current treatment landscape. OBJECTIVE: To present an analysis of health care resource utilization (HCRU) and costs associated with the treatment of patients with advanced or metastatic NSCLC in the United States between 2010 and 2019. METHODS: Patients with locally advanced or metastatic NSCLC who initiated first-line (1L) systemic treatment between January 1, 2010, and June 30, 2019, were included from the HealthCore Integrated Research Database using a previously developed claims-based predictive model algorithm. Mean total HCRU and costs and mean per-person-per-year (PPPY) HCRU and costs were estimated for 2 follow-up periods: the time during the entire follow-up period and the time during the 1L treatment period. Distribution of treatment classes (defined as chemotherapy, ICIs, targeted therapies, and others) were also analyzed by index year. RESULTS: 27,257 patients met the eligibility criteria and were included in the analysis. The mean duration of follow-up for all patients was 16.6 months (median 10.6 months), and the median time to discontinuation of 1L treatment was 2.8 months. The number of outpatient visits accounted for the majority of HCRU across the entire study follow-up (mean 97.7 in total and 147.1 PPPY) and for the 1L treatment period (mean 46.3 in total and 167.5 PPPY). The total mean cost across the entire study follow-up was $158,908 ($250,942 PPPY). For the 1L treatment period, the total mean cost was $72,760 ($271,590 PPPY). Total mean outpatient costs for systemic anticancer treatment were $61,797 for the entire study follow-up ($85,609 PPPY) and $27,138 during the 1L treatment period ($92,412 PPPY). Total costs increased over the study duration, which were mainly due to increasing outpatient costs for systemic therapy. In both follow-up periods, inpatient costs, other outpatient costs (nonsystemic therapy-related costs), and pharmacy costs remained relatively stable but still accounted for more than 60% of the total costs. Analysis of treatment classes over time showed that chemotherapy was the most frequently used treatment, regardless of line of therapy. A trend was observed for increased ICI use from 2015 onward. CONCLUSIONS: Despite the improvement in treatment options, a high economic burden associated with the treatment of NSCLC still exists. The total costs have been increasing, mainly driven by outpatient costs for systemic therapy, which might reflect the greater use of ICIs for advanced NSCLC. Costs for inpatient services, other outpatient services, and pharmacy services remained stable but still accounted for the majority of the economic burden. Further studies are required to assess the impact of innovative treatments on the disease management costs of advanced NSCLC.

Sertraline Pediatric Registry for the Evaluation of Safety: Design and Clinical Characteristics of Pediatric Patients Prescribed Sertraline.

Objectives: To describe the study design and clinical characteristics of patients in the Sertraline Pediatric RegIstry for The Evaluation of Safety (SPRITES). Methods: SPRITES is an open-label postmarketing study of development and safety outcomes in patients aged 6 to 16 years treated with sertraline (with or without psychotherapy) compared with psychotherapy alone for up to 3 years in the United States. Baseline data included demographics and psychiatric history. Primary outcomes included measures of cognitive and emotional development (Trails B, Behavior Rating Inventory of Executive Function [BRIEF]), physical development (height and weight), and pubertal status (Tanner Stage). Data were also collected on present/lifetime risk of suicide-related events using the Columbia-Suicide Severity Rating Scale. Results: SPRITES enrolled 941 patients between the ages of 6 and 16 years. Patients' baseline mean age was 11.9 years (2.9), 57.2% were female, and 84.8% were white. Most patients (78.4%) had an anxiety disorder, and 15.6% were diagnosed with obsessive-compulsive disorder. The mean age at onset of first mental illness was 7.9 years. A higher percentage of sertraline-treated patients compared with patients who received no pharmacological treatment received prior psychotherapy (59.0% vs. 34.4%, p < 0.001), psychotropic medications for a psychiatric disorder (14.1% vs. 3.3%, p < 0.001), and other non-sertraline selective serotonin reuptake inhibitors (8.6% vs. 1.2%, p < 0.001). Most patients were moderately ill on the Clinical Global Impressions-Severity scale, and a higher (p < 0.001) percentage of sertraline-treated patients had a moderate-to-severe mental illness score compared with the no pharmacological treatment group (73.0% vs. 57.8%, respectively). Although patients at high and imminent risk of a suicidal event were excluded at study entry, the sertraline-treated patients reported higher levels of lifetime suicidal behavior compared with patients treated with no pharmacological treatment (5.8% vs. 2.5%, p = 0.039). Conclusions: Baseline data from this nonrandomized observational study suggest that patients prescribed sertraline are reflective of a more mentally ill study population compared with patients receiving psychotherapy.

Pulmonary and cardiovascular safety of inhaled insulin in routine practice: The Exubera Large Simple Trial (VOLUME).

OBJECTIVE: VOLUME is a randomized, open-label, post-approval pragmatic trial aiming to evaluate long-term pulmonary and cardiovascular safety of Exubera® (EXU; insulin human [rDNA origin] Inhalation Powder) in routine clinical practice. The primary study objective is to compare risk of persistent decline in forced expiratory volume in 1 second (FEV1) among patients treated with and without EXU. RESEARCH DESIGN AND METHODS: Patients eligible to take EXU per approved local label were randomized to EXU or routine care and followed per usual care, with scheduled FEV1 tests at baseline, 6 months, and yearly.Randomization halted in October 2007 after Pfizer announced it would stop marketing EXU due to low sales. EXU patients were subsequently transitioned to usual care and all patients were followed for 6 additional months. RESULTS: Although there was insufficient power to evaluate the primary endpoint (37% of the planned 5,300 were randomized), the study provided important descriptive information.Per the primary endpoint definition, more EXU group patients (n = 8) experienced a persistent decline in FEV1 (n = 0 in usual care). Using a broader, clinically relevant pre-specified supplementary definition of persistent decline, similar numbers were observed in the EXU (n = 27) and usual care (n = 24) groups. Slightly more pulmonary and allergic serious adverse event composite endpoints were seen in the EXU group. There were no consistent treatment group differences in the cardiovascular composite endpoint, all-cause mortality, or glycemic control. CONCLUSIONS: Clinically important declines in lung function that persisted more than 60 days were uncommon and of similar frequency in Exubera and usual care. CLINICALTRIALSGOV: NCT00359801.

Implications of product withdrawal on a post-approval pragmatic trial: The VOLUME study experience.

INTRODUCTION: Many clinical trials terminate early due to safety and efficacy concerns, and less often due to unexpected "positive" findings. However, early termination of post-approval (Phase IV) pragmatic randomized trials for commercial reasons is less frequent, may be more complex, and may require added flexibility in closure methods, including short term follow-up. VOLUME was a randomized, open-label, post-approval pragmatic clinical trial (PCT) or large simple trial that terminated early due to product withdrawal. The aim of this paper is to describe circumstances unique to post-approval PCTs that may require a closure amendment rather than immediate study termination, and our recommendations for operational study closure in these circumstances. We use the VOLUME case study throughout to provide a practical example. METHODS: Study closeout considerations at the study level include: notifying external governance bodies, e.g., data monitoring committees (DMC), and scientific steering committees (SSC); executing a study closure amendment; notifying and training of study physicians; and institutional review board (IRB)/ethics committee (EC) approvals. Study closure considerations at the patient level focus on patient safety and include: patient notification, efficient transition to alternative treatments, the need for re-consenting; and drug supply shortages. CONCLUSIONS: Early study closeout logistics require careful analysis, detailed planning, and close coordination, and are ideally considered at the study planning phase. Lessons learned from the VOLUME closeout should help other researchers devise contingencies when terminating post approval pragmatic trials that utilize a marketed product.ClinicalTrials.gov: NCT00359801.

Acute nonarteritic anterior ischemic optic neuropathy and exposure to phosphodiesterase type 5 inhibitors.

INTRODUCTION: Nonarteritic anterior ischemic optic neuropathy (NAION), a rare visual disorder, has been reported in men using phosphodiesterase type 5 inhibitors (PDE5i) for erectile dysfunction. AIM: We examined whether intermittent use of PDE5i is associated with acute NAION onset within approximately five half-lives following drug ingestion. METHODS: One hundred two ophthalmology centers in the United States and Europe identified potential cases of NAION. An expert adjudication committee conducted a blind review of the records of those with recent PDE5i use to classify cases as Definite, Possible, or not NAION. Subjects provided information on PDEi use via telephone interview. Each NAION case's PDE5i exposure immediately prior to onset was compared against his recent patterns of use in an observational case-crossover design. A sample size of 40 cases with intermittent PDE5i exposure in the 30 days prior to NAION onset was needed to detect an odds ratio (OR) of 3.0 with 80% power. MAIN OUTCOME MEASURES: The daily relative risk for acute NAION on days within five half-lives of PDE5i use vs. other days was estimated via an OR obtained from conditional logistic regression. RESULTS: Among 43 Definite NAION cases with PDE5i exposure in the prior 30 days, the OR was 2.15 (95% confidence interval [CI]: 1.06, 4.34). When 21 Possible NAION cases were included (n = 64), the OR was 2.36 (95% CI: 1.33, 4.19). CONCLUSIONS: We found an approximately twofold increased risk of acute NAION within five half-lives of PDE5i use compared with use in a more prior time period. Bias from inaccurate recall of exposure was unlikely to have substantially affected the results. Based on our results, we estimate that weekly use of PDE5i adds three NAION cases per 100,000 men 50 years and older annually.

Lessons learned in the conduct of a global, large simple trial of treatments indicated for schizophrenia.

Large, "practical" or streamlined trials (LSTs) are used to study the effectiveness and/or safety of medicines in real world settings with minimal study imposed interventions. While LSTs have benefits over traditional randomized clinical trials and observational studies, there are inherent challenges to their conduct. Enrollment and follow-up of a large study sample of patients with mental illness pose a particular difficulty. To assist in overcoming operational barriers in future LSTs in psychiatry, this paper describes the recruitment and observational follow-up strategies used for the ZODIAC study, an international, open-label LST, which followed 18,239 persons randomly assigned to one of two treatments indicated for schizophrenia for 1 year. ZODIAC enrolled patients in 18 countries in North America, South America, Europe, and Asia using broad study entry criteria and required minimal clinical care intervention. Recruitment of adequate numbers and continued engagement of both study centers and subjects were significant challenges. Strategies implemented to mitigate these in ZODIAC include global study expansion, study branding, field coordinator and site relations programs, monthly site newsletters, collection of alternate contact information, conduct of national death index (NDI) searches, and frequent sponsor, contract research organization (CRO) and site interaction to share best practices and address recruitment challenges quickly. We conclude that conduct of large LSTs in psychiatric patient populations is feasible, but importantly, realistic site recruitment goals and maintaining site engagement are key factors that need to be considered in early study planning and conduct.
