ObjectivesTo compare the short-term safety and efficacy of centanafadine, an investigational treatment, versus long-acting controlled-release methylphenidate hydrochloride (methylphenidate, Foquest) among adult patients with attention-deficit/hyperactivity disorder (ADHD), using matching-adjusted indirect comparison (MAIC).MethodsThis anchored MAIC used pooled individual patient data (IPD) from two centanafadine trials (NCT03605680, NCT03605836) and published aggregate data from one methylphenidate trial (NCT02139124). Using propensity scores, IPD from the centanafadine trials were reweighted to match the aggregate baseline characteristics of the methylphenidate trial.

BackgroundAgitation is a common neuropsychiatric symptom of Alzheimer's disease; however, limited information exists on how measurable changes in agitated behaviors relate to overall caregiver experience. We sought to describe agitated behaviors measured by the Cohen-Mansfield Agitation Inventory (CMAI) score among individuals with Alzheimer's disease living in US community-based settings and experience of their caregivers.MethodsAn online survey was conducted (08/26/2021-09/24/2021) among adult caregivers who lived with and provided unpaid care for an individual with Alzheimer's disease.

This study assessed treatment preferences of physicians treating adult patients with ADHD in both countries.

Methods: An online discrete choice experiment (DCE) was conducted (October 4-20, 2023) among physicians from Dynata's US and Canadian panel who treated adult patients with ADHD.

To compare long-term safety and efficacy outcomes of centanafadine versus lisdexamfetamine dimesylate (lisdexamfetamine), methylphenidate hydrochloride (methylphenidate) and atomoxetine hydrochloride (atomoxetine), respectively, in adults with attention-deficit/hyperactivity disorder (ADHD) using matching-adjusted indirect comparisons (MAICs). Patient-level data from a centanafadine trial (NCT03605849) and published aggregate data from a lisdexamfetamine trial (NCT00337285), a methylphenidate trial (NCT00326300) and an atomoxetine trial (NCT00190736) were used. Patient characteristics were matched in each comparison using propensity score weighting.

Background: Attention-deficit/hyperactivity disorder (ADHD) has been shown to pose considerable clinical and economic burden; however, research quantifying the excess burden attributable to common psychiatric comorbidities of ADHD among pediatric patients is scarce. This study assessed the impact of anxiety and depression on healthcare resource utilization (HRU) and healthcare costs in pediatric patients with ADHD in the United States.

Methods: Patients with ADHD aged 6-17 years were identified in the IQVIA PharMetrics Plus database (10/01/2015-09/30/2021).

Objective: To compare safety and efficacy of centanafadine versus methylphenidate hydrochloride extended release (ER; Concerta) in adults with ADHD.

Methods: Without head-to-head trials, anchored matching-adjusted indirect comparisons (MAIC) of adverse event rates reported across trials and mean change from baseline in Adult ADHD Investigator Symptom Rating Scale (AISRS) score between centanafadine and methylphenidate hydrochloride ER were conducted. Pooled patient-level data from two centanafadine trials (NCT03605680/NCT03605836) and aggregate data from one published methylphenidate hydrochloride ER trial (NCT00937040) were used.

Background: Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous condition with extensive psychiatric comorbidities. ADHD has been associated with substantial clinical and economic burden; however, little is known about the incremental burden specifically attributable to psychiatric comorbidities of ADHD in adults.

Objective: To assess the impact of psychiatric comorbidities, specifically anxiety and depression, on health care resource utilization (HRU) and costs in treated adults with ADHD in the United States.

Background: Head-to-head trials comparing centanafadine, an investigational therapy for adults with attention-deficit/hyperactivity disorder (ADHD), with other treatment options are lacking.

Objective: To compare safety and efficacy outcomes of centanafadine sustained-release vs lisdexamfetamine dimesylate (lisdexamfetamine), atomoxetine hydrochloride (atomoxetine), and viloxazine extended-release (viloxazine ER), respectively, using matching-adjusted indirect comparison (MAIC).

Methods: This MAIC included patient-level data pooled from 2 centanafadine trials (NCT03605680 and NCT03605836) and published aggregate data from comparable trials of 3 comparators-lisdexamfetamine (NCT00334880), atomoxetine (NCT00190736), and viloxazine ER (NCT04016779)-in adult patients with ADHD.

Objective: Attention-deficit/hyperactivity disorder (ADHD) medication is frequently associated with adverse events (AEs), but limited real-world data exist regarding their costs from a payer's perspective. Therefore, this study evaluated the healthcare costs associated with common AEs among adult patients treated for ADHD in the US.

Methods: Eligible adults treated for ADHD were identified from a large US claims database (1 October 2015-30 September 2021).

Article Synopsis
  • The study aimed to compare the clinical characteristics, healthcare costs, and outcomes (institutionalization and mortality) of patients with Alzheimer’s dementia who exhibit agitation versus those who do not.
  • Researchers analyzed data from the Reliant Medical Group, focusing on patients aged 55 and older diagnosed with Alzheimer's between January 2016 and March 2020, defining two cohorts: those with agitation and those without.
  • Findings indicated that patients in the agitation cohort experienced more comorbidities, received higher costs of care (about $4287 more per year), and faced increased rates of death and shorter time to institutionalization compared to the non-agitation cohort.

Background: Knowledge of risk factors for attention-deficit/hyperactivity disorder (ADHD) may facilitate early diagnosis; however, studies examining a broad range of potential risk factors for ADHD in adults are limited. This study aimed to identify risk factors associated with newly diagnosed ADHD among adults in the United States (US).

Methods: Eligible adults from the IQVIA PharMetrics® Plus database (10/01/2015-09/30/2021) were classified into the ADHD cohort if they had ≥ 2 ADHD diagnoses (index date: first ADHD diagnosis) and into the non-ADHD cohort if they had no observed ADHD diagnosis (index date: random date) with a 1:3 case-to-control ratio.

Background: The proportion of patients with post-traumatic stress disorder (PTSD) that remain undiagnosed may be substantial. Without an accurate diagnosis, these patients may lack PTSD-targeted treatments and experience adverse health outcomes. This study used a machine learning approach to identify and describe civilian patients likely to have undiagnosed PTSD in the US commercial population.

To estimate the economic burden of posttraumatic stress disorder (PTSD) in the United States civilian and military populations from a societal perspective. A prevalence-based and human capital approach was used to estimate the total excess costs of PTSD in 2018 from insurance claims data, academic literature, and governmental publications. Excess direct health care costs (pharmacy, medical), direct non-health care costs (research and training, substance use, psychotherapy, homelessness, disability), and indirect costs (unemployment, productivity loss, caregiving, premature mortality) associated with PTSD were compared between adults with PTSD and adults without PTSD, or the general population if information was not available for adults without PTSD.

Attention-deficit/hyperactivity disorder (ADHD) is associated with substantial clinical burden as individuals transition to adulthood, including higher rates of comorbidities, mortality, incarceration, and psychiatric hospitalizations than in individuals without ADHD. These higher rates likely contribute to substantial economic burden as well. To provide a comprehensive evaluation of the economic burden associated with ADHD in the US adult population.
