Clinical trials are a cornerstone of medical research, playing a critical role in the development of new treatments and therapies. At Pfizer, we are committed to driving medical progress and enhancing patient care through rigorous clinical research. Our clinical trial programs play a vital role in advancing new treatments, vaccines, and therapies that have the potential to improve lives.
What are clinical trials?
Clinical trials are meticulously designed research studies that evaluate the safety and efficacy of new medical interventions, including drugs, vaccines, and other therapies. These trials are necessary for advancing scientific understanding and improving patient outcomes. All medicines and vaccines that become available, have been first tested in clinical trials. There are 4 phases, each with a specific purpose[1]:
Phase 1: This initial phase focuses on assessing the safety of a new treatment or vaccine, including its side effects and how it is metabolized and excreted by the body. It typically involves a small group of healthy volunteers or patients.
Phase 2: In this phase, the treatment is given to a larger group of patients to further evaluate its safety and effectiveness for the condition being studied. Researchers also determine the optimal dose and schedule for administering the treatment.
Phase 3: This pivotal phase involves an even larger group of patients and aims to confirm the treatment's effectiveness, monitor side effects, and compare it to standard treatments for the condition being studied. Phase 3 trials provide the critical data needed for regulatory approval.
Phase 4: After a treatment has been approved and is on the market, Phase 4 trials continue to monitor its long-term safety and effectiveness in a larger, more diverse population.
Why We Conduct Clinical Trials
Pfizer's clinical trial efforts in Canada are crucial for several reasons:
1. Advancing Medical Knowledge: Clinical trials provide valuable data that help researchers understand how new treatments work and how they can be used to treat different medical conditions.
2. Improving Patient Care: By developing new treatments, we can offer patients more effective and safer options for managing their health, ultimately enhancing their quality of life.
3. Ensuring Safety and Effectiveness: Clinical trials are essential for verifying that new treatments are safe and effective before they are made available to the public.
4. Meeting Regulatory Requirements: Regulatory authorities, such as Health Canada, require clinical trial data to approve new treatments. Conducting rigorous clinical trials ensures that Pfizer meets these requirements and can bring new treatments to Canadian patients.
5. Leveraging Canada's Expertise and Diversity: Canada is a leader in clinical trials, with a robust regulatory framework and a diverse population that provides valuable data for Pfizer's research. By collaborating with Canadian institutions and healthcare providers, we can leverage local expertise and resources to conduct its trials to the highest standards.
Patient Care Comes First
Our clinical trial efforts are driven by a patient-centric approach, ensuring that the safety and well-being of participants are the top priorities.
We collaborate with a wide range of partners, including academic institutions, healthcare providers, and other pharmaceutical companies, to leverage expertise and resources and advance medical research more effectively.
We are committed to making its clinical trials as inclusive as possible, reflecting the diverse populations that will ultimately use these treatments. We recognize the importance of ensuring that our research reflects the real-world demographics of patients, including underrepresented groups. By actively reaching out to diverse communities and removing barriers to participation, we aim to generate data that is more representative and applicable to the broader patient population.
Ensuring Patient Safety and Privacy
We are committed to protecting the people who take part in our clinical trials, and to upholding the highest ethical standards as we seek safe and effective ways to prevent or treat diseases. Before a trial begins, it requires review and approval by regulatory authorities and Research Committees/Institutional Boards to ensure that it meets all safety and ethical standards.
Participants are fully informed about their rights and the trial, including its purpose, procedures, potential risks, and benefits, and they must provide informed consent before participating.
Oversight of our clinical trials and participants are closely monitored by healthcare professionals. Pfizer is committed to data protection measures to ensure that participants' personal information is kept confidential in compliance with applicable privacy laws. And as always, patients can ask questions about any aspect of the study, and leave the study at any time.
Clinical trials are a vital part of Pfizer's mission to develop new treatments and improve patient care. By conducting rigorous and ethical clinical trials, we can advance medical knowledge, improve patient outcomes, and bring new treatments to market. Our commitment to patient safety, collaboration, and innovation ensures that we conduct our trials with the highest standards of care and integrity.
In Canada, Pfizer is dedicated to conducting clinical trials that reflect the diverse population and meet the highest regulatory standards. We are proud to partner with Canadian institutions and healthcare providers to advance medical research and improve the health and well-being of patients across the country.
