1 Future of Pharmaceutical Quality and the Path to Get There Lawrence Yu, Ph.D. Deputy Director, Office of Pharmaceutical Quality FDA Center for Drug Evaluation and Research INTERPHEX 2018, April 18, 2018, Javits Center, NYC

2 FDA s Vision for Pharmaceutical Quality Quality is the underpinning of everything US FDA/CDER does Assures patients have access to safe and effective drug products Over-the-counter Prescription Innovator (Brand) Generic 2

3 Patients and Caregivers Expect Their Drugs: Are safe, efficacious, and have the correct identity Deliver the same performance as described in the label Perform consistently over their shelf life Are made in a manner that ensures quality Will be available when needed 3

4 A High Quality Product = 1. A product that reproducibly delivers the therapeutic benefit to the consumer as stated in the label 2. Is free of defects 3. Presents no undeclared risk (e.g., isn t contaminated) 4

5 FDA s Quality Journey The US FDA quality initiative began more than a decade ago with the 21 st Century Initiative to modernize FDA s regulation of the pharmaceutical quality of drugs. A journey that is still on-going... Vision: A maximally efficient, agile, flexible pharmaceutical manufacturing sector that reliably produces high quality drugs without extensive regulatory oversight. -Dr. Janet Woodcock 5

Drug Shortage Reasons 14% 8% 6% 2% 4% 35% Quality: Facility Remediation Efforts Quality: Product Manufacturing Issues Discontinuation of Product Raw Materials (API) Shortage Other Component Shortage 31% Increased Demand Loss of Manufacturing Site 6

11 Economic and Technological Drivers of Generic Sterile Injectable Drug Shortages Woodcock, J; Wocinska, M. Clin. Pharmacol. & Thera. 93: (2013) The fundamental problem we identify is the inability of the market to observe and reward quality. This lack of reward for quality can reinforce price competition and encourage manufacturers to keep costs down by minimizing quality investments

14 Performance-based Regulation A regulatory approach that focuses on desired, measurable outcomes, rather than prescriptive processes, techniques, or procedures. Performancebased regulation leads to defined results without specific direction regarding how those results are to be obtained At the Nuclear Regulatory Commission, performancebased regulatory actions focus on identifying performance measures that ensure an adequate safety margin and offer incentives to improve safety without formal regulatory intervention by the agency 14 14

15 Types of Regulations Stages of Organizational Production and Types of Regulation Stage of Production Planning Acting Outputs (both good and bad) Type of Regulation Management- Based Means- Based Performance- Based Pharmaceutical regulation should be designed to improve the performance of individual and organizational behavior in ways that protect and promote public health Coglianese, C., & Lazer, D.

29 Quality by Design ICH Q8(R2) Pharmaceutical Quality by Design (QbD) is a systematic approach to development that begins with predefined objectives and emphasizes product and process understanding and process control, based on sound science and quality risk management Quality by Design Tools Prior knowledge Risk assessment Design of experiments (DOE) and data analysis Process analytical technology (PAT) tools 29

30 Quality by Design: Objectives To achieve meaningful product specifications that are based on clinical performance To increase process capability and reduce product variability and defects by enhancing product and process design, understanding, and control To increase product development and manufacturing efficiencies To enhance post-approval change management 30

37 McKinsey: Flawless: From measuring failures to building quality robustness in pharma There s the challenge of shifting mind-sets across industry that has focused predominantly on compliance rather than on truly knowing the root causes and effects on quality issues 37

38 Creating a Culture of Quality S. Srinivasan and B. Kurey, Harvard Business Review, 2014 Culture of quality: An environment in which employees not only follow quality guidelines but also consistently see others taking quality-focused actions, hear others talking about quality, and feel quality all around them Four Essentials of Quality Maintaining a leadership emphasis on quality Ensuring message credibility Encouraging peer involvement Increasing employee ownership and empowerment 38

39 Characteristics of Culture for Quality Clearly visible, engaged and unwavering senior management support for quality Clearly articulated vision and values Active and ongoing engagement with customers to continually identify and address current and evolving needs Clearly stated quality goals Performance expectations for all individuals throughout the company that clearly link to quality goals Appropriate incentives which can favor monetary or recognition-based awards, depending on individual circumstances. 39

40 Continuous Improvement Leaders must take the lead in quality improvement Investments in quality improvement must be substantial Modern tools for improvement must be put to use Flawless execution, focusing on quality, not compliance/enforcement Communications among industry, patients, and regulators must be open and carefully maintained 40
