Pharmacovigilance (PV) is a crucial component of the pharmaceutical industry, ensuring the safety and efficacy of drugs. A career in PV offers numerous opportunities for making a meaningful impact on public health. As the field continues to evolve, PV professionals will continue to remain at the forefront of ensuring the safety and efficacy of medications. Whether you are a PharmD, MD, PhD, or have a background in any life sciences, PV presents a rewarding and much needed career.

What is Pharmacovigilance?

PV, also known as drug safety, plays a pivotal role in the pharmaceutical industry in ensuring the safety of approved and investigational products throughout their lifecycle. According to the World Health Organization (WHO), PV is defined as the science and activities related to the detection, assessment, understanding, and prevention of adverse events or any other drug-related problem. This involves a broad range of activities, from monitoring adverse events during clinical trials to ensuring that post-marketing surveillance continues to keep patients safe. The main tasks revolve around any adverse events or any events with drug compounds that need to be looked into.

For every clinical study, an important goal is to prove to regulatory authorities, such as the Food and Drug Administration (FDA), with evidence that the drug works by being both efficacious and safe for humans to use. This includes the overall monitoring of the drug's adverse events with a thorough understanding of how adverse events of a drug work from a clinical and pharmaceutical standpoint in terms of pharmacokinetics (how the body affects a drug) and pharmacodynamics (how the drug affects the body).

Understanding Adverse Events

An adverse event is any undesired reaction within a patient's body that is caused by either a drug or a molecule. These events are crucial considerations during clinical trials. Knowing the importance of a side effect within clinical trials for a drug development process and then understanding what to do with that information plays a key role in PV. General Responsibilities of Pharmacovigilance Professionals PV professionals are responsible for several key activities:

1. Assessing Drug Profiles: This involves evaluating drug profiles for both approved and investigational products. Often, the drug molecules are not novel, which means new therapies can be a combination of two drugs. Whenever there is a new product that is already approved while using it in conjunction with a novel one, then PV professionals must research any previously known data of adverse events of the materials and the active ingredients within this new product.

2. Data Monitoring: Continuous monitoring of adverse events is essential. After researching adverse events, one must be able to recognize changes in the frequency and severity of adverse events. As new data emerges, PV professionals assess whether the safety profile of the drug is improving or worsening and make recommendations accordingly. If the data provides evidence that the drug is making a positive impact or situations are worsening, then the implications of what to do with this information fall under PV.

3. Quality Checking: Ensuring that all communicated information is accurate is critical. Within the pharmaceutical industry, this is called quality checking. Ensuring that any information that gets communicated from PV to any external departments, healthcare professionals, patients, and regulatory agencies is accurate. It ensures that the data, opinions, results, and conclusions that a PV is presenting are accurate. Accuracy in scientific communication is a cornerstone of effective PV. Nothing else matters if your data isn’t correct!

The Structure of Pharmacovigilance Departments

Let’s review the responsibilities of the pharmacovigilance team by comparing the two major “departments”: clinical research and non-clinical research.

Clinical Research

In clinical research, PV professionals focus on assessing the safety of drugs during clinical trials. The work here is very different from any work a PV might have outside of clinical trials. Individuals who are experts in the clinical development process within PV usually sit in this group. This involves determining the risk-versus-benefit and giving the approval that the safety profile of this study justifies the continued development of the drug.

Remember in order to get the drug approved, you have to have phase one, two, and three trials with statistically significant data that shows the drug is efficacious and safe for the proposed indications.

PV's involvement spans from pre-clinical trials through phases 1, 2, and 3, and even after the drug is approved, through ad hoc analyses and phase 4 studies. This is to keep assessing the safety profile throughout the whole life cycle of the drug. PVs are involved in the whole process from the beginning of the drug discovery process.

Non-Clinical Research

Non-clinical research involves examining the following types of data in the real-word: - Any previously known adverse events - Long-term adverse events - Risks associated with dosing variations of the medications - Risks with missing doses of the medications which occur often with patients These external data points are extremely important to the safety profile for a better understanding of a drug outside of controlled clinical settings. They were found by the non-clinical trial PV group.

Sub-Departments within Pharmacovigilance

PV departments typically include sub-departments, each with specialized roles:

1. Surveillance: The responsibility of risk management and detection falls under this department. It is a long-term data analysis and management. PV professionals would monitor all available data about the drug products they are assigned to overlook. This includes data that is external from clinical trials. It consists of providing analysis and summaries of data on a large scale. Some roles under this sub-department are PV scientists and drug safety physicians.

2. Systems: This group builds and maintains the software systems needed to manage vast amounts of data. As you can imagine, there is a vast amount of data coming in from clinical trials and external sources, and software is needed to deal with the information in an understandable format. The responsibility of setting up systems for different types of data that other teams might need, while making sure they are aligned with updated regulations regarding clinical trial data, patient information, and regulatory requirements is crucial. This team must be able to scientifically understand the data and the implications of it. It's more of a technical role combined with individuals of scientific backgrounds.

Who Can Work in Pharmacovigilance?

PV is accessible to individuals with a scientific background, including those with degrees in life sciences, medicine, and pharmacy. While higher-level degrees such as MDs, PhDs, and PharmDs are preferred, relevant experience and skills can also help pave the way to a successful career in PV. PharmDs in particular, are well-suited for PV roles due to their extensive training in therapeutics and drug safety. PharmDs have an understanding of adverse drug profiles from a clinical and medicinal chemistry point of view and how to analyze them which makes them have a perfect background for this functional area.

Why Pursue a Career in Pharmacovigilance?

A career in PV is ideal for those who enjoy analyzing data, drawing conclusions, and making recommendations based on scientific evidence. Being part of the drug development process from the start, and seeing how it impacts patients’ lives is rewarding. PV professionals play a crucial role in ensuring patient safety and public health, making it a rewarding and impactful career.
