In the normal course of a day, most of us won’t think about clinical research. It only crosses our minds if it affects us directly. Perhaps a new treatment becomes available for a chronic condition, or a loved one finds relief with a new medication.
Yet, every day, thousands of people work to help achieve every extra minute, improved symptom, or better day that clinical research can offer us. And every breakthrough starts in the same place: with a volunteer. The people who choose to take part in clinical trials make it possible for new medicines to move from the lab into everyday care. Without them, progress would stall. Because of them, new options continue to reach the patients who need them most.
The people who join clinical trials are everyday individuals making extraordinary contributions. Some are living with a chronic condition and want better options for themselves or their families. Others volunteer because they believe in advancing science. The experiences of these clinical trial participants help turn research into progress.
From Idea to Approval: the Start of Every Medication
Each new medicine starts as an idea in a lab, but it only becomes available after years of testing through clinical trials. This process is designed to answer essential questions: is the treatment safe, does it work as intended, and is it better than what’s already available? This is a crucial step in the drug approval process.
The phases of clinical research build on one another. Early studies focus on safety and finding the right dose. Later trials involve larger groups of patients, and they measure effectiveness and compare the results with existing therapies. Even after approval, research continues to track long-term outcomes and monitor safety in broader populations.
In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) and the National Institute for Health and Care Excellence (NICE) review the evidence before deciding whether a new treatment can be licensed and made available on the NHS.
Why People Join Clinical Trials
People join clinical trials for all sorts of reasons. Some are motivated by the thought of helping to advance medical science, while others hope they’ll play a role in finding a new treatment for future generations.
Velocity’s research shows that participants under the age of 24 are the most likely to be motivated by the reimbursement available for clinical trials. By their late twenties and early thirties, participants are just as likely to want to contribute to new treatment approvals as to receive payment. For many, this is the point where personal benefit and the desire to support scientific discovery carry equal weight.
As participants get older, altruism becomes the driving factor behind taking part in clinical research. The majority of older adults said they took part to help advance medical research, often citing the hope of creating better options for future generations.
Clinical Trial Success Stories
In recent years, the impact of clinical research has gone far beyond what we might have imagined even just a generation ago. Each advance represents years of study and thousands of participants, not to mention hundreds of alternative treatments that didn’t make it through the clinical trials process to reach approval.
In neurology, Alzheimer’s treatments such as donanemab and lecanemab have been approved in the last few years. Both slow disease progression and buy people more meaningful time with those they love. The approval of these medicines is directly attributable to the individuals who participated in clinical trials, including participants at Velocity sites across the U.S.
Cancer research has also advanced thanks to the efforts of trial participants. Immunotherapy drugs, once considered experimental, are now used to treat certain cancers, changing the outlook for patients who had few options left.
The rapid development of COVID-19 vaccines is another milestone. Studies involving tens of thousands of healthy volunteers allowed for the development of vaccines in record time, saving lives and helping communities return to normal after the pandemic.
And progress continues across chronic conditions such as diabetes, cardiovascular disease, and respiratory illness. Each year, dozens of new treatment approvals are made, all of them made possible by the experiences of thousands of clinical trial participants
Beyond Medicine: What We Learn from Clinical Trials
Most of us will only consider clinical research in terms of approved drugs that end up on our pharmacy shelves. After all, these are the medicines that have a noticeable impact on our own lives. But even studies that don’t lead to a new medication contribute valuable insights.
Clinical studies don’t just focus on medications; they are also used to investigate new treatment protocols or medical devices. Trials can reveal that an existing medicine works better in a new group of patients, or that using a specific treatment improves its effectiveness.
Many trials will show that an experimental therapy isn’t effective. While this is disappointing for those involved, the information gathered in these clinical trials is still vitally important. By ruling out ineffective options, researchers can focus on more promising approaches. This is how science moves forward: every study, every data point, every volunteer helps us to understand and advance modern medicine.
The Safeguards in Place
Every clinical trial in the U.K. must follow strict rules before it can begin. Studies are reviewed by an independent Research Ethics Committee and regulated by the MHRA. These bodies ensure that research is designed responsibly and that participant safety is the top priority. Once a study is underway, monitoring continues. Researchers regularly check results, track side effects, and share updates with regulators.
Every decision starts with the right information. Read our Participant FAQs to find out more about joining a clinical trial.
The Future Starts Today
Clinical research has already reshaped everyday treatments, improving the outcomes of those with serious conditions like cancer or Alzheimer’s disease. The next advances will focus on rare diseases, gene therapies, and personalised medicine, areas where the impact of clinical trials could be just as life-changing for millions of people.
By joining a clinical trial, you could help contribute to medical advances that may help you, your loved ones, and future generations.
