The opioid crisis highlights the need to increase access to naloxone, possibly through regulatory approval for over-the-counter sales. To address industry-perceived barriers to such access, the Food and Drug Administration (FDA) developed a model drug facts label for such sales to assess whether consumers understood the key statements for safe and effective use.In this label-comprehension study, we conducted individual structured interviews with 710 adults and adolescents, including 430 adults who use opioids and their family and friends. Eight primary end points were developed to assess user comprehension of each of the key steps in the label. Each of these end points included a prespecified target threshold ranging from 80 to 90% that was evaluated through a comparison of the lower boundary of the 95% exact confidence interval.The results for performance on six primary end points met or exceeded thresholds, including the steps "Check for a suspected overdose" (threshold, 85%; point estimate [PE], 95.8%; 95% confidence interval [CI], 94.0 to 97.1) and "Give the first dose" (threshold, 85%; PE, 98.2%; 95% CI, 96.9 to 99.0). The lower boundaries for four other primary end points ranged from 88.8 to 94.0%. One exception was comprehension of "Call 911 immediately," but this instruction closely approximated the target of 90% (PE, 90.3%; 95% CI, 87.9 to 92.4). Another exception was comprehension of the composite step of "Check, give, and call 911 immediately" (threshold, 85%; PE, 81.1%; 95% CI, 78.0 to 83.9).Consumers met thresholds for sufficient understanding of six of eight components of the instructions in the drug facts label for naloxone use and came close on two others. Overall, the FDA found that the model label was adequate for use in the development of a naloxone product intended for over-the-counter sales.

Since the 2012 fungal meningitis outbreak caused by a compounded drug that had been prepared under inappropriate conditions, the FDA’s experience in monitoring pharmacy compounding has demonstrated the need for further improvement in compounding practices.

This review considers master protocols, which involve the study of one or more interventions in multiple diseases or of a single disease with multiple interventions.

The FDA and the Next Wave of Drug Abuse In responding to the opioid crisis, the FDA needs to recognize shifting trends in the addiction landscape. Taking a systematic approach to monitoring such trends should allow the agency to intervene promptly and appropriately to protect the public from associated risks.

To improve access to biologic drugs, Congress authorized the FDA to create an abbreviated pathway for approving biologics that are “biosimilar” to approved products. Reconciling the science of biosimilar development with a new regulatory framework is challenging.

BACKGROUND There is an urgent need to determine whether oversulfated chondroitin sulfate (OSCS), a compound contaminating heparin supplies worldwide, is the cause of the severe anaphylactoid reactions that have occurred after intravenous heparin administration in the United States and Germany. METHODS Heparin procured from the Food and Drug Administration, consisting of suspect lots of heparin associated with the clinical events as well as control lots of heparin, were screened in a blinded fashion both for the presence of OSCS and for any biologic activity that could potentially link the contaminant to the observed clinical adverse events. In vitro assays for the activation of the contact system and the complement cascade were performed. In addition, the ability of OSCS to recapitulate key clinical manifestations in vivo was tested in swine. RESULTS The OSCS found in contaminated lots of unfractionated heparin, as well as a synthetically generated OSCS reference standard, directly activated the kinin-kallikrein pathway in human plasma, which can lead to the generation of bradykinin, a potent vasoactive mediator. In addition, OSCS induced generation of C3a and C5a, potent anaphylatoxins derived from complement proteins. Activation of these two pathways was unexpectedly linked and dependent on fluid-phase activation of factor XII. Screening of plasma samples from various species indicated that swine and humans are sensitive to the effects of OSCS in a similar manner. OSCS-containing heparin and synthetically derived OSCS induced hypotension associated with kallikrein activation when administered by intravenous infusion in swine. CONCLUSIONS Our results provide a scientific rationale for a potential biologic link between the presence of OSCS in suspect lots of heparin and the observed clinical adverse events. An assay to assess the amidolytic activity of kallikrein can supplement analytic tests to protect the heparin supply chain by screening for OSCS and other highly sulfated polysaccharide contaminants of heparin that can activate the contact system.

Three trials tested related hypotheses regarding genotype-informed dosing strategies for anticoagulants yet arrived at different results. Careful assessment of these trials can help to reframe the dialogue regarding evidentiary assessment of coumarin pharmacogenetics.

Successful development of future targeted therapies will require the flexibility to rapidly evaluate combination regimens involving new targeted agents in a single development program. The FDA has therefore developed draft guidance on drug co-development.

There have been ongoing concerns about the safety of the diabetes drugs containing rosiglitazone (Avandia, Avandaryl, and Avandamet) — a thiazolidinedione antidiabetic agent indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. In 2007, a meta-analysis of controlled clinical trials found increases in the risk of myocardial infarction and a near-significant increased risk of death from cardiovascular causes when rosiglitazone was compared with placebo or with standard diabetes drugs.1 Following an advisory committee meeting held in July 2007, the U.S. Food and Drug Administration (FDA) added information about the possibility . . .

Clinical trials are our best vehicle for turning medical information that we may think is true into evidence that we know, within reasonable limits, to be true. Since the introduction of random assignments to treatment in the 1930s,1 the clinical trial has been in continuous evolution. Among the major milestones have been the development of methods to perform randomization; the convening of data and safety monitoring committees; the formulation of stopping guidelines for safety, efficacy, and futility; and many others. Indeed, the clinical trial landscape is far different today from what it was over 80 years ago, when investigators first . . .

Scientific advances in the past decade have made the clinical testing of somatic-cell therapy and gene therapy a reality. Early trials in humans suggest that important new diagnostic and therapeutic tools are on the horizon. The objectives of this article are to examine the regulation of somatic-cell and gene therapy by the Food and Drug Administration (FDA) in the context of the agency's traditional role in the development of biologic products and to stimulate discussion in areas in which policy is still being formulated. The technology of somatic-cell and gene therapy has moved from the bench to clinical evaluation with . . .
