Risk Evaluation Mitigation Strategy in the Pharmaceutical Industry

In the pharmaceutical industry, a Risk Evaluation Mitigation Strategy (REMS) is a crucial tool for managing the risks associated with certain medications. The FDA requires a REMS for drugs that carry serious risks, such as birth defects or addiction.

A REMS can be as simple as a medication guide or as complex as a restricted distribution program. For example, the medication Thalomid has a REMS that includes a medication guide and a patient enrollment form. This ensures that patients and healthcare providers are aware of the medication's risks and take necessary precautions.

The goal of a REMS is to minimize the risks associated with a medication while still making it available to patients who need it. By implementing a REMS, pharmaceutical companies can help prevent adverse events and protect public health.

Risk Evaluation is a critical step in the risk evaluation mitigation strategy (REMS) process. It involves evaluating identified risks to determine if they are acceptable or not, and if not, prioritizing and mitigating them.

The facilitator/lead for the review team generates an executive summary detailing the scope of the review, major findings, and recommendations. This summary includes assigned responsibilities and timeframes for follow-up.

To determine acceptability of risks, consider information specific to each product. The results of the risk assessment should be logical and clear, with sub-procedures driving the overall risk scores.

A hazard is a well-defined thing that can become a risk when exposed to a procedure or action.

An agent or a chemical can be a hazard, and so can a high-pressurized steam system or an 80-degree C WFI system.

As long as a hazard is left alone, it is not a risk. But if we handle an agent or propagate it in a fermentor, it can become a risk.

A car is also a hazard, and it's not a risk until someone performs an action that puts it in harm's way, such as driving into another car.

Using a hazard outside its intended use can also create a risk, like attempting to cross a river in a car.

Even a parked car can become a risk if left unattended during a heat wave.

Risk is a well-defined concept that arises from hazards or threats. A hazard is anything that has the potential to cause harm, such as a high-pressurized steam system or an 80-degree C WFI system.

Risks are created when a hazard is exposed to a procedure or action. For example, if we handle an agent, even from a low-risk group in our production process, propagate it in a fermentor, spin it around in a centrifuge, it can become a risk.

The likelihood and consequence of a risk are crucial factors in determining its overall risk score. Risk can be visualized in a two-dimensional graph, with likelihood on the x-axis and consequence on the y-axis.

To evaluate risks, we need to identify, prioritize, and mitigate them. We must consider the information specific to each product and determine the acceptability of the risks. The facilitator/lead for the review team will generate an executive summary that details the scope of the review, major findings, and recommendations.

Here are the four key pillar components in a REMS program:

These components are essential in reducing the risks associated with opioid medications, such as accidental overdose and opioid overutilization. Pharmacists play a crucial role in reducing these risks by verifying prescriptions, consulting with patients, and monitoring their compliance.

The scope of a risk analysis is crucial in determining the boundaries of the review. A narrow focus results in a more detailed analysis, while a broader scope requires a more general overview. A clear definition of the boundaries will start the review off in an effective manner and inform the choice of risk analysis methodology.

The number of medications with REMS requirements has been growing rapidly since 2007, with several hundred medications approved with REMS.

This growing trend presents challenges in ensuring consistent access to these medications and guaranteeing high-quality patient care.

The FDA launched a website in mid-2015 to provide access to REMS@ FDA, a list of medications with REMS requirements.

The website provides safety information, pharmacy enrollment forms, and required actions for pharmacists who dispense the REMS medication.

REMS@ FDA is an essential resource for pharmacists to ensure consistent access to these products for patients.

Components of REMS may include one or more of the following:

A comprehensive risk assessment consists of a series of consecutive steps, starting with assessment. The five steps are: assessment, mitigation, evaluation, corrective action plan (CAP), and performance evaluation.

To develop a mitigation strategy, the risk assessment team will not only have assessed the risk at each situation but has also made their recommendations for each situation. The team will then continue the review question by question until the entire process or operation has been analyzed.

The risk assessment team will consider the following when developing a mitigation strategy: what mitigation measures are needed, what can be applied easily and quickly, what needs to be implemented in the future, and what needs to be presented to management before implementation will be possible.

Here are some key steps to consider when creating a CAP:

The human factor plays a very important role for successful risk mitigation, and it's essential to verify the efficiency of mitigation measures by using performance indicators and evaluating and verifying that the mitigation measures actually worked as intended.

A different take: Risk Measures

A collaborative effort is crucial in conducting a successful risk assessment. This involves assembling an experienced and knowledgeable team that includes production, operating, and maintenance personnel, as well as design and/or operating engineers.

The team should also include specific skills as needed, such as product purity, QA/QC, waste handling, chem/bio, structural engineer, and radiation expert. Knowledge of design standards, regulatory codes, past documented and potential future operational errors, accidents, and incidents, as well as maintenance challenges, brings a hands-on reality to the review.

Any risk assessment done by one single person will most likely not cover all relevant aspects. That is also the reason that risk assessments cannot be outsourced to a consultant. A consultant can challenge the conclusions, review the assessments, but not drive the process, manage the data, and keep the focus for the group.

Here are the essential team members for a successful risk assessment:

Performance is a critical aspect of a mitigation strategy. It's essential to verify that the chosen risk mitigation measures are working as intended.

Human factor plays a significant role in the success of risk mitigation. Sometimes, a solution or engineering control can invoke a new problem, shifting the risk to a different area.

To evaluate the efficiency of mitigation measures, use Performance Indicators to verify that the risk is reduced. This involves evaluating and verifying that the mitigation measures worked as intended.

A 3 month, 6 month, and 1 year follow-up is recommended to assess the durability of the mitigation measures. This ensures that the procedures are robust and can withstand the test of time.

Implementing a risk evaluation mitigation strategy involves several key steps.

Risk assessments should be conducted regularly to identify potential risks and their likelihood of occurrence.

A thorough risk assessment involves identifying hazards, assessing their likelihood and potential impact, and determining control measures to mitigate them.

The risk matrix is a useful tool for evaluating the likelihood and potential impact of a risk.

The risk matrix categorizes risks into four quadrants: high likelihood and high impact, high likelihood and low impact, low likelihood and high impact, and low likelihood and low impact.

Risk mitigation plans should be developed and implemented to address high-risk areas.

A risk mitigation plan outlines the steps to be taken to mitigate a risk and the resources required to implement the plan.

Regular reviews and updates of the risk evaluation mitigation strategy are essential to ensure its effectiveness.

This involves reviewing the risk assessment, risk matrix, and risk mitigation plans to ensure they remain relevant and effective.

Delays in Generic Launches can be a significant challenge for the industry. Nearly 40% of new FDA approvals are subject to REMS, which can hinder generic competition.

Brand manufacturers can prevent generic competitors from accessing their products due to certain REMS elements, making it difficult for generic applicants to complete bioequivalence testing and development.

This can result in lost savings on small-molecule drugs of at least $5.4 billion annually, according to the Generic Pharmaceutical Association.
