FDA plans to permanently transition older formulations to ADFs

  • Improve access to the newer formulations through generic competitors
  • Final guidance on development of generic versions of approved ADF opioids
  • Developing appropriate, improved testing methodologies for evaluating abuse deterrence for both brand name  and generic opioid drug products

FDA statement on implementation of agency’s streamlined development and review pathway for consumer tests that evaluate genetic health risksCapture.JPG

Genetic health risk (GHR) testing helps understanding of  individual risk for developing diseases

  • Make more informed lifestyle choices
  • Direct-to-consumer (DTC) access to GHR tests available
  • Opportunities for  detection of additional genetic conditions and diseases

GHR Testing has its own risks

  • Incorrect or misleading information leading to health choices without medical advice
  • Adaptive regulatory framework for unique  challenges of new technology
  • Balance efficient pathway to customer access without sacrificing FDA oversight

Flexible approach for regulating novel medical advances such as GHR

  • Lessons learned from authorization of  first DTC GHR and carrier screening tests (23andMe)
  • GHR tests to be exempted from premarket review under certain conditions
  • Manufacturers would have to come to FDA for a one-time review; no furtjer review of new tests
  • Established special controls  in a separate de novo classification order

Capture.JPGFDA statement on new steps to improve FDA review of shared Risk Evaluation and Mitigation Strategies to improve generic drug access

Risk Evaluation and Mitigation Strategy (REMS) to ensure that the benefits of the drug outweigh the risks

  • Medication Guide or patient package insert
  • Communication plan
  • “Elements to Ensure Safe Use” (ETASU) e.g. prescriber training, patient counseling

Use of shared REMS to prevent use as a tool to block generic competition

  • Encourage use of shared system between innovator and generic companies
  • Reduce  likelihood for branded drug companies to use existing REMS to slow generic competition
  • Streamline submission and review process for shared system REMS
  • Use of a single Drug Master File (DMF) for shared system REMS submissions

Capture.JPGFDA takes unprecedented step toward more efficient global pharmaceutical manufacturing inspections 

FDA will recognize eight EU drug regulatory authorities as capable of conducting inspections of manufacturing facilities that meet FDA requirements

  • Austria, Croatia, France, Italy, Malta, Spain, Sweden, UK
  • Implementation of US-EU Mutual Recognition Agreement
  • Will now rely on the inspectional data obtained by these eight regulatory agencies

EU Commission determined (6/17) that the FDA “has the capability, capacity and procedures in place to carry out GMP inspections at a level equivalent to the EU.”

  • Enables the FDA and the EU to avoid duplication of drug inspections
  • Allows regulators to devote resources to other high risk manufacturing facilities
