Real-World Data Collection from Expanded Access Case Studies for the Treatment of Nontuberculous Mycobacterial Infection with Clofazimine.

Background: Due to its indolent nature, nontuberculous mycobacteria (NTM) are increasing in global prevalence as a cause of pulmonary infections and are difficult to treat with traditional antibiotics. Here, we study the repurposing of clofazimine (CFZ) to treat NTM through expanded access in a single health system. Our main objectives are to describe the feasibility of accessing and analyzing expanded access data and to generate hypotheses regarding CFZ use in NTM treatment.

National landscape assessment of academic medical center support for expanded access to investigational products.

Unlabelled: Expanded access (EA) provides a pathway for the clinical use of investigational products (drugs, biologics, and medical devices) for patients who are without satisfactory therapeutic options and for whom a clinical trial is not available. Academic medical centers (AMCs) are likely to encounter EA requests, but it is unknown what support is available at these institutions for physicians seeking EA for patients.

Methods: A landscape assessment was conducted at AMCs, focused on those within the Clinical and Translational Science Awards (CTSA) consortium.

Adapting an Expanded Access program to enable investigational treatments for COVID-19.

Retrospective case studies of initiatives supported by the National Institutes of Health's Clinical and Translational Science Award (CTSA) hubs can be used to identify facilitators and barriers of translational science. This case study investigates how a CTSA Expanded Access program adapted to changing FDA guidance issued in 2020 to support clinicians' treatment of COVID-19 patients in Michigan. We studied how this program changed throughout the pandemic to support physicians' requests for remdesivir, convalescent plasma, and other uses of unapproved drugs and novel medical devices.

Morphological cell profiling of SARS-CoV-2 infection identifies drug repurposing candidates for COVID-19.

The global spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the associated disease COVID-19, requires therapeutic interventions that can be rapidly identified and translated to clinical care. Traditional drug discovery methods have a >90% failure rate and can take 10 to 15 y from target identification to clinical use. In contrast, drug repurposing can significantly accelerate translation.

Role of CTSA institutes and academic medical centers in facilitating preapproval access to investigational agents and devices during the COVID-19 pandemic.

Introduction: With no approved treatments for COVID-19 initially available, the Food and Drug Administration utilized multiple preapproval pathways to provide access to investigational agents and/or medical devices: Expanded Access, Emergency Use Authorizations, and Clinical Trials. Regulatory units within an Academic Medical Center (AMC), including those part of the Clinical and Translational Science Award (CTSA) consortium, have provided support for clinicians in navigating these options prior to the pandemic. As such, they were positioned to be a resource for accessing therapies during the COVID-19 public health emergency.

Traditional drug discovery methods have a >90% failure rate and can take 10-15 years from target identification to clinical use. In contrast, drug repurposing can significantly accelerate translation.

The Critical Role of Medical Institutions in Expanding Access to Investigational Interventions.

The U.S. federal government provides two tracks for eligible patients to obtain access outside clinical trials to investigational interventions currently under study for potential clinical benefits: the Food and Drug Administration's expanded access pathway and the pathway created by the more recent Right to Try Act.

Cleaning and Sterilization of Used Cardiac Implantable Electronic Devices With Process Validation: The Next Hurdle in Device Recycling.

Objectives: This study sought to develop a validated, reproducible sterilization protocol, which could be used in the reprocessing of cardiac implantable electronic devices (CIEDs).

Background: Access to cardiac CIED therapy in high-income and in low- and middle-income countries varies greatly. CIED reuse may reduce this disparity.

Pacemaker recycling: A notion whose time has come.

The purpose of this paper is to summarize the need, feasibility, safety, legality, and ethical perspectives of pacemaker reutilization in low- and middle-income countries (LMICs). It will also describe, in-depth, Project My Heart Your Heart (PMHYH) as a model for pacemaker reuse in LMICs. The primary source of the discussion points in this paper is a collection of 14 publications produced by the research team at the University of Michigan and its collaborative partners.

Regulatory Considerations in the Design and Manufacturing of Implantable 3D-Printed Medical Devices.

Three-dimensional (3D) printing, or additive manufacturing, technology has rapidly penetrated the medical device industry over the past several years, and innovative groups have harnessed it to create devices with unique composition, structure, and customizability. These distinctive capabilities afforded by 3D printing have introduced new regulatory challenges. The customizability of 3D-printed devices introduces new complexities when drafting a design control model for FDA consideration of market approval.

Access to Investigational Drugs: FDA Expanded Access Programs or "Right-to-Try" Legislation?

Purpose: The Food and Drug Administration Expanded Access (EA) program and "Right-to-Try" legislation aim to provide seriously ill patients who have no other comparable treatment options to gain access to investigational drugs and biological agents. Physicians and institutions need to understand these programs to respond to questions and requests for access.

Methods: FDA EA programs and state and federal legislative efforts to provide investigational products to patients by circumventing FDA regulations were summarized and compared.

Sleep apnea treatment after stroke (SATS) trial: is it feasible?

Sleep apnea affects more than half of patients with acute ischemic stroke and is associated with poor stroke outcome. This pilot study assessed the feasibility of a randomized, sham-controlled continuous positive airway pressure (CPAP) trial in subjects with acute ischemic stroke. Subjects identified with sleep apnea based on an apnea-hypopnea index≥5 on overnight polysomnography or portable respiratory monitoring within 7 days of onset of stroke symptoms were randomized to receive active or sham CPAP for a 3-month period.

Predictors of habitual snoring and obstructive sleep apnea risk in patients with asthma.

Background: A high prevalence of obstructive sleep apnea (OSA) symptoms was reported in patients with asthma. Our goal was to evaluate factors associated with habitual snoring and OSA risk in these patients.

Methods: Patients with asthma were surveyed at specialty clinics with the Sleep Apnea scale of the Sleep Disorders Questionnaire (SA-SDQ) and questions about the frequency of asthma symptoms (National Asthma Education and Prevention Program guidelines), followed by medical record review.

Sleep staging and respiratory events in refractory epilepsy patients: Is there a first night effect?

Purpose: We performed this analysis of possible first night effects (FNEs) on sleep and respiratory parameters in order to evaluate the need for two serial night polysomnograms (PSGs) to diagnose obstructive sleep apnea (OSA) in epilepsy patients.

Methods: As part of a pilot multicenter clinical trial investigating the effects of treating sleep apnea in epilepsy, two nights of PSG recording were performed for 40 patients with refractory epilepsy and OSA symptoms. Sleep architecture was examined in detail, along with respiratory parameters including apnea/hypopnea index (AHI) and minimum oxygen saturation.

Correlates of daytime sleepiness in patients with asthma.

Background And Purpose: Patients with asthma often complain of daytime sleepiness, which is usually attributed to a direct effect of asthma on nocturnal sleep quality. We investigated this and other potential explanations for daytime sleepiness among asthmatics.

Patients And Methods: One hundred fifteen adult asthmatics were assessed for perceived daytime sleepiness (one question item), subjective sleepiness (Epworth Sleepiness Scale score, ESS), obstructive sleep apnea risk (Sleep Apnea scale score within Sleep Disorders Questionnaire, SA-SDQ), asthma severity step, relevant comorbid conditions, and current asthma medications.

Evaluation of sham non-invasive ventilation for randomized, controlled trials in ALS.

Non-invasive positive pressure ventilation (NIV) treatment of advanced respiratory insufficiency prolongs survival in ALS. To investigate the critical question of whether earlier initiation of NIV might provide additional benefit, a randomized trial with an appropriate placebo is needed. This study evaluated sub-therapeutic (sham) continuous positive airway pressure as a potential placebo.

Obstructive sleep apnea in epilepsy patients: the Sleep Apnea scale of the Sleep Disorders Questionnaire (SA-SDQ) is a useful screening instrument for obstructive sleep apnea in a disease-specific population.

Objective: To determine useful cutoffs on the Sleep Apnea scale of the Sleep Disorders Questionnaire (SA-SDQ) in an epilepsy population.

Background: Epilepsy and obstructive sleep apnea (OSA) frequently coexist, and treating OSA in epilepsy patients may reduce seizure frequency and improve daytime sleepiness. The SA-SDQ, a 12-item validated measure of sleep-related breathing disorders, may be a useful tool to screen epilepsy patients for OSA, although appropriate cutoff points have not been established in this population.

Identification and treatment of obstructive sleep apnea in adults and children with epilepsy: a prospective pilot study.

Objective: To determine the effect of treating obstructive sleep apnea (OSA) on seizure frequency in adults and children with epilepsy in a prospective study. Several case series documented an improvement in seizure control with treatment of coexisting OSA, but published series did not sample a clinic population, were not prospective in design, and did not account for concurrent changes in antiepileptic drug (AED) doses or levels.

Patients And Methods: Adult patients and the parents of pediatric patients seen in the University of Michigan Epilepsy and Pediatric Neurology Clinics were given validated questionnaires.
