Why Phase 1 Clinical Trials Use “Generally Healthy” Volunteers

Volunteering for a phase 1 clinical trial is an impactful way to contribute to advancing medical research. Phase 1 clinical trials rely on willing individuals who offer their bodies for science. But a common requirement you’ll often hear for participating in phase 1 clinical trials is that of “generally healthy” volunteers.

Phase 1 clinical trials request “generally healthy” volunteers for a multitude of reasons, several of which we will explore below.

The importance of phase 1 clinical trials

Clinical trials are conducted in three phases, each with specific objectives.

Phase 1 trials primarily center on testing medicines and vaccines for safety and tolerability in human subjects.  These trials are an important early step in the drug development process. They identify any side effects before progressing to Phases 2 and 3, which assess the drug’s efficacy in patients with specific medical conditions.

The role of generally healthy volunteers

Phase 1 clinical trials typically involve generally healthy volunteers, usually adults aged 18 to 55. These volunteers help researchers evaluate a drug’s safety and potential side effects before testing it on either the general public or on individuals with the targeted medical condition. By conducting initial tests on healthy individuals, scientists can better understand how the human body tolerates and processes to eliminate the drug without additional complications from pre-existing health conditions.

Eligibility criteria and screening process

To participate in a Phase 1 clinical trial, interested individuals must undergo a medical screening process, which includes assessing their overall health and medical history. The “screening visit” resembles an annual physical at your Primary Care Provider. Specific eligibility criteria are considered, such as:

  • Sex
  • Age
  • Weight
  • BMI
  • Medical background

The screening process includes urine tests and blood work to assess every aspect of the participants’ health.

Reproductive criteria may also apply, depending on the study’s design. Often the participants, males and females, are asked to use efficient birth control during and after the study (from weeks to months). The screening process helps guarantee that potential participants meet the necessary requirements and can safely partake in the trial.

Informed consent and ethical considerations

Before joining a Phase 1 clinical trial, the study team provides comprehensive information about the study, including its potential risks and benefits. Participants must give their informed consent, which involves signing a document outlining their rights and study details. Informed consent is an ethical cornerstone of clinical research, making sure that volunteers fully understand the study’s implications and can make a voluntary decision to participate.

Time commitment and clinic stay

Phase 1 trials for healthy participants can vary in duration, ranging from several days to months. Participants are closely monitored during their stay at the clinical research facility throughout the trial, which can last from a few days to several weeks. This time commitment may require volunteers to take time off from work or make arrangements with their families. Most clinical research facilities compensate participants to cover related expenses, and volunteers are encouraged to participate in various activities during their free time.

Making a difference: The impact of generally healthy volunteers

The contributions of volunteers who are considered generally healthy are immeasurable. Their willingness to participate in Phase 1 clinical trials sets the foundation for safe and effective treatments that can ultimately save lives. By helping researchers understand drug safety and side effects early in the development process, these volunteers pave the way for groundbreaking advancements in medical science.

Encouraging more participation

Clinical trials take place worldwide, and there are continuous opportunities for individuals to become volunteers. The impact of participation extends beyond personal benefits, by reaching underserved and underrepresented populations. Clinical researchers emphasize the importance of healthy volunteers, urging more people to consider becoming part of these transformative endeavors.

Are you healthy enough for phase 1 biotrial clinical trials?

Participating in phase 1 Biotrial clinical trials as a volunteer is an altruistic and impactful way to contribute to advancing medical research. Medical research volunteers play an important role in evaluating drug safety, which sets the stage for developing life-saving treatments. As clinical trials continue to progress, the contributions of these selfless individuals become even more critical in finding new therapies and cures for various diseases. If you meet the eligibility criteria and have the time to participate, your decision to become a volunteer can make a significant difference in the lives of countless patients worldwide.

As you can see, there are a number of reasons having individuals who qualify as “generally healthy” participate in a clinical trial is a good idea. What’s more, there are also many benefits to joining a clinical trial from the participant’s perspective, including earning extra money, helping others, and contributing to science.
