The Integrated Review: FDA Modernizes the Review of New Drug Marketing Applications.

New Drug Applications and Biologics Licensing Applications submitted to the US Food and Drug Administration (FDA) are reviewed by an interdisciplinary team of regulatory scientists that includes medical officers, clinical pharmacologists, toxicologists, statisticians, and drug labeling experts. Upon review of an applicant's submitted evidence from nonclinical studies, clinical trials, and manufacturing capabilities, the review team evaluates the benefits and risks of the drug and makes a scientifically-informed decision. As part of a multi-year, multi-phase New Drugs Regulatory Program Modernization effort, the FDA has recently redesigned how it reviews and documents its decisions with regard to marketing applications.

Endpoints in Heart Failure Drug Development: History and Future.

Heart failure (HF) patients experience a high burden of symptoms and functional limitations, and morbidity and mortality remain high despite successful therapies. The majority of HF drugs in the United States are approved for reducing hospitalization and mortality, while only a few have indications for improving quality of life, physical function, or symptoms. Patient-reported outcomes that directly measure patient's perception of health status (symptoms, physical function, or quality of life) are potentially approvable endpoints in drug development.

Use of a Systems Pharmacology Model Based Approach Toward Dose Optimization of Parathyroid Hormone Therapy in Hypoparathyroidism.

We present an application of a quantitative systems pharmacology (QSP) model to support a regulatory decision, specifically in assessing the adequacy of the proposed dosing regimen. On January 23, 2015, the US Food and Drug Administration (FDA) approved Natpara (human parathyroid hormone (PTH)) to control hypocalcemia in patients with hypoparathyroidism. Clinical trial results indicated that although once-daily PTH reduced calcium and vitamin D dose requirement while maintaining the normocalcemia, the regimen was not adequate to control hypercalciuria.

Ten-Year Experience for the Center for Drug Evaluation and Research, Part 2: FDA's Role in Ensuring Patient Safety.

Background: The purpose of this study was to describe the role of the US Food and Drug Administration (FDA) in ensuring the safety of patients receiving investigational drugs under expanded access.

Methods: To better define FDA's role in the review of requests for expanded access, multiple queries of FDA's Center for Drug Evaluation and Research (CDER) document tracking system were performed. The queries identified reasons for, and outcomes of, expanded access requests for investigational drugs that were either not allowed to proceed or denied over a 10-year time period.
