Risk-Based Regulatory Review

What is the Desired State?

Performance-Based Regulation

“A regulatory approach that focuses on desired, measurable outcomes, rather than prescriptive

processes, techniques, or procedures.

Performance-based regulation leads to defined results without specific direction regarding how

those results are obtained…..

Performance-based regulatory actions focus on identifying performance measures that ensure an adequate safety margin and offer incentives for

companies to improve safety without formal regulatory intervention by the agency.”

Translating Risk into Performance

RISK PERFORMANCE • Transparency • Uncertainty • Robustness

– Control strategy – QRM

• Consistency • Balance (Benefit:Risk)

• Reliability • Sustainability • Continual Improvement

7

Desired State: Quality Expectations

• Patients expect their medicines: – Are safe, efficacious & have correct identity – Deliver the performance described on the label – Perform consistently over their shelf-lives – Are made in a manner that ensures quality – Are available when needed

• Industry provides appropriate transparency regarding risk (QRM) such that regulators have confidence a control strategy is appropriately established & maintained through the product lifecycle

FDA & Industry are generally aligned . . .

8

What Constitutes Good Risk-based Regulatory Review?

• Increase use of Annual Reports & control w/in PQS

• Integrate regulatory review w/inspection to transparently link the relationship of PQS to Established Conditions

• Delineate level of risk according to product type & product categories, i.e., complex vs. simple dosage forms

• Identify & communicate quality risks relevant to patient safety & efficacy

• Do not penalize firms for transparently sharing risk assessments & additional development data

— Appropriate level of detail in regulatory submissions

• Reduce post approval supplements • Establish unified approach & expectations across industry

globally

9

Characterization of Risks

What is the Current State?

10

Current State: • FDA concerns:

– Lack of detailed transparency in risk assessments – Absence of coherent & complete description & rationale

of a product control strategy – Uncertainty in lifecycle & Management

• Industry concerns: – Inconsistency in regulatory assessments – Integration between inspections & assessments is clunky

• Overlap of IR queries w/inspection observations • Increased scrutiny of development studies

– Absence of incentives for flexible regulatory approaches for post-approval changes, i.e., w/in PQS

– Inconsistency in assessment of individual CQA controls – Global divergence

11

Concerns We’ve Heard About Risk

• Regulators want to understand how & when industry performs risk assessments – What is the level of expertise & process to establish a

product control strategy & manage changes through development & after commercialization?

– How are manufacturing process changes managed? – Are formal risk assessment approaches used to

evaluate changes? – Are changes systematically managed under a QRM

paradigm & robust change management system? – Who participates in risk assessment exercises? – How is knowledge/experience captured & transferred?

12

Risk

13

• Companies perform risk assessments to: – Understand the product quality attributes – Establish appropriate control strategies – Establish a baseline for subsequent process improvements

• Evaluate impact of process trending & adjustments • Evaluate process optimization proposals

– Distinguish risk & characterize uncertainty – Determine & confirm predictability

• Regulators evaluate risk assessments – To ensure appropriate control strategy is established – To ensure robustness of RA approach – NOT to repeat risk assessments

Uncertainty Prior Knowledge

CQA Scoring (RPN #)Severity (highest) x Uncertainty = RPN [≤ 5, non-CQA]; [> 5, CQA]

Severity

Biological activity (CB ELISA)

Pharmacokinetics

Immunogenicity

Safety

Can Risk Assessments be validated?

Do Risk Assessments adequately

predict whether a control reliably mitigates a risk?

14

Leveraging Knowledge & Experience Emphasis on Control Strategy

What is the Path to Desired State?

15

Opportunity for Alignment?

• Leverage Industry/Regulator Knowledge Interface: – Evaluate the combination of registration content & the

Pharmaceutical Quality System • Is Quality Risk Management robust? • Does the product control strategy assure quality, safety,

efficacy & supply reliability? • Will & management provide assurance of requisite quality

through the product lifecycle?

• Performance-based regulatory assessment should: – Focus on relevant risks – Appropriately address uncertainty – Ensure Established Conditions are scientifically

justified, not arbitrarily contrived

16

Regulatory Authorities possesses a breadth of knowledge. Pharmaceutical Industry possesses a depth of knowledge.

Leveraging Knowledge & Experience

17

Control Strategy by Design • Start with the Patient Understand patient needs – TARGET PRODUCT PROFILE Understand the process – Does it deliver what the patient needs? What needs to be controlled to assure quality for the patient?

• Develop analytical method(s) to monitor quality risks • Assess materials & process risks to quality Understand criteria (CQAs) needed to assure product quality Process understanding (Not all ‘critical parameters’ carry equal risk) Differentiate CPP/change management based on residual risk

• Determine which risks to quality require a test How does process deal with risks to quality – ENHANCED knowledge?

• Determine where optimal control is positioned Control on inputs, parameters, IPCs, outputs OR a mix

• Establish specification for all critical controls Test method + acceptance criterion OR Rationale for how CQA is controlled w/o testing

• Can Control Strategy provide a measure of product performance? 18

Risk-Based Regulatory Review of Control Strategy

• A robust control strategy in conjunction w/robust & management will demonstrate quality through the product lifecycle. Evaluate control strategy relative to the quality of the risk

assessments used to establish it.

Review & assess & management processes & systems at inspection.

Focus on functional relationships that are relevant to product CQAs.

Reduce &/or eliminate focus on unnecessary low risk issues.

Assess control strategy relative to consistency, supply reliability & sustainability through the product lifecycle.

Barriers What is Lost w/o Risk-Based Regulatory Review?

Next Steps

What are Barriers & Next Steps?

21

Barriers to Risk-Based Regulatory Review

• Lack of transparency Omission of risks in regulatory submissions Regulatory expectations & queries

• Discontinuity in & management thru lifecycle • Unaccommodating submission format: How to effectively present risk assessments & QRM

approach? How to holistically convey product control strategy? How can industry align content with IQA template? QOS?

• Increasing global regulatory divergence 22

What is Lost w/o Risk-Based Regulatory Review?

• Opportunities to . . . Improve confidence in quality Expedite regulatory reviews & approvals Reduce post approval change submissions Reconcile risk with performance Embrace continual improvement Increase mutual trust Align global regulatory expectations Enhance efficiency

23

Next Steps • Joint industry & regulator QRM workshop • Pilot alternative regulatory submission

options Repurpose CTD-QOS Emphasize product control strategy as a

reflection of quality performance Reconcile integrated submission & inspection

criteria

• Collaborate on ICH development & expansion ICH Q12 Mutual Recognition & transparency
