What Are Clinical Trials

What are clinical trials?

Clinical trials are important studies in the field of medicine that test new treatments, diets, or medical devices. Before these trials, researchers test advanced new drugs and devices in laboratories. If the results are promising and safe, these drugs are then evaluated on people through clinical trials.

The main purpose of clinical trials is to find out if new treatments and devices are safe and effective for people. Clinical trials require volunteers. They can access advanced and innovative treatments years before they could be accessed with the conventional medical route, and usually, all costs are covered by the organisations running the clinical trials, like research institutions or pharmaceutical companies.

What do clinical trials study?

Clinical trials can be designed to study and evaluate:

  • New Treatments: They test new drugs, combinations of drugs, or new methods of treatment. This can also include changes in how much medicine is given and how it’s given.
  • Managing Symptoms and Side Effects: They look for new drugs or alternative therapies to reduce symptoms of a disease or the side effects of treatments.
  • Prevention: They study if certain drugs or changes in lifestyle can reduce the risk of getting a disease.
  • Screening: They develop tests to detect diseases early, especially in people at high risk.
  • Diagnosis: They create new ways to detect diseases, like new types of scans or tests.
  • Understanding Risks and Causes: They explore how genetics, lifestyle, and other factors affect the risk of getting a disease.

What are the main goals of clinical trials?

The goals of clinical trials are to determine if a new treatment or procedure:

  • Is safe.
  • Has side effects.
  • Works better than existing treatments.
  • Improves the quality of life for patients.

Clinical trials can have various results. Some may show that a new treatment works better than current ones, while others might offer insights into side effects or how the body reacts to the drug. 

Not all trials lead to breakthroughs. Sometimes, they show that a new treatment doesn’t work well or has more side effects than existing treatments. But even this information is helpful as it adds to our understanding of diseases and how to manage them. 

Researchers also look at how treatments affect daily life, like the number of hospital visits needed. Studies focusing on these day-to-day effects are often called quality of life studies and are a key part of many trials.


Are clinical trials safe?

Clinical trials prioritise safety and provide close monitoring of participants, offering several benefits:

  • Close Monitoring: Participants are carefully watched for any side effects or reactions, often more closely than in regular medical care.
  • Strict Protocols: These trials follow detailed plans that are thoroughly reviewed by ethical and regulatory groups. This ensures high safety standards.
  • Data Collection: The health of participants is carefully recorded and analysed, offering a detailed understanding of how a treatment affects an individual.

Importantly, participants in clinical trials have the autonomy to withdraw from the study at any point, for any reason, without any obligation to provide an explanation. This ensures that participation is entirely based on individual comfort and consent

What are the advantages of participating in a clinical trial?

Participating in a clinical trial offers several potential advantages for patients:

  • Early Access to New Treatments: Participants can try cutting-edge treatments not yet available to the public, which can be crucial for those who haven’t had success with standard treatments.
  • Close Medical Supervision: Participants receive frequent and detailed medical care, often more than usual.
  • Contribution to Research: Participation helps advance medical research, leading to new treatments that could help others in the future.
  • Potential Personal Benefit: While not guaranteed, participants might find the new treatment more effective than standard options.
  • Detailed Information and Support: Participants often get a lot of information and education about their condition and the treatment being tested, along with supportive care during the trial.

Researchers and medical science also benefit from clinical trials:

  • Advancing Medical Knowledge: Clinical trials are essential for developing new medications, medical devices, and treatment protocols. They help in understanding disease mechanisms and treatment efficacy.
  • Improving Treatment Standards: Findings from trials can lead to improvements in standard care practices, enhancing overall patient care.
  • Safety and Efficacy Data: Trials provide critical data on the safety and efficacy of new treatments, which is necessary for regulatory approval.
  • Tailored Treatments: Clinical trials can also contribute to the field of personalized medicine, helping to determine which treatments are most effective for specific patient groups. 

Finally, clinical trials bring benefits to our community:

  • Public Health Improvements: Successful trials can lead to new treatments that improve public health outcomes.
  • Economic Benefits: Developing effective treatments can reduce healthcare costs in the long term by improving treatment outcomes and reducing the need for ongoing care.
  • Educating Patients and Professionals: Clinical trials can also serve an educational role, informing patients, healthcare providers, and the public about medical conditions and their management.
