AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice of public scientific workshop; request for comments.

The Food and Drug Administration (FDA) is announcing a public scientific workshop to discuss dystrophin protein quantification methodologies for human tissue. This workshop is being cosponsored by the National Institutes of Health (NIH). The purpose of the workshop is to discuss currently available methodologies and to identify scientific knowledge gaps and opportunities for improving dystrophin protein detection in the context of drug development. The intended audiences for this workshop are scientists and clinicians involved in the acquisition, measurement, and analysis of proteins associated with Duchenne Muscular Dystrophy (DMD).

SUPPLEMENTARY INFORMATION:

FDA and NIH are cosponsoring this scientific workshop to discuss current methodologies being used in drug development and scientific research for DMD. Recent scientific advances present an opportunity for the development and validation of robust methods for the objective, reliable, and quantitative measurement of DMD-associated proteins.

I. Background

Dystrophinopathies result from genetic mutations in the dystrophin gene that decrease dystrophin protein expression levels and result in altered dystrophin function. These changes can lead to muscle degeneration and, in many patients, downstream pathologies including inflammation and fibrosis that interfere with muscle regeneration, loss of movement, orthopedic complications, and ultimately respiratory and cardiac failure.

II. Scope of the Scientific Workshop

The workshop will include sessions which will focus on current technologies used in the detection of dystrophin. Presentations will provide overviews of the technologies (including limitations, detection sensitivities, linearity, and reproducibility). A panel discussion will help identify development challenges for each method. Muscle biopsy collection, sample handling, reference materials, and image analysis will also be discussed.

FDA will post the agenda and other background material approximately 2 days before the public scientific workshop at: http://www.fda.gov/​Drugs/​NewsEvents/​ucm432429.htm.
