How Do Psychedelics Clinical Trials Work: Phases Explained
Clinical trials are research studies performed with human participants to evaluate a medical, surgical, or behavioral intervention (such as psychedelic-assisted the rapy including MDMA therapy for PTSD, psilocybin-assisted therapy for depression, ibogaine or mescaline therapy). They are the primary way that researchers find out if a new treatment, like a new drug such as psilocybin for anxiety, works and is safe.
Psychedelic Clinical Trial Key Terms and Meanings
Understanding key terms and status meanings is crucial for navigating the landscape of clinical trials. Here’s a breakdown to help clarify these concepts:
Key Terms:
Clinical Trial: A research study in which participants receive specific interventions according to the research plan or protocol created by the investigators.
Protocol: The detailed plan of a clinical trial outlining the study’s objectives, design, methodologies, statistical considerations, and organization.
Informed Consent: A process in which researchers provide potential and enrolled participants with information about a clinical trial’s purposes, risks, benefits, and alternatives, allowing them to make an informed decision about participation.
Placebo: An inactive substance or treatment that looks the same as, and is administered in the same way as, the active drug being tested. It’s used to assess the drug’s effectiveness by comparison.
Blind Study: A study design where the participant, the medical staff, or both do not know which study group the participant is in or which treatment they are receiving to prevent bias.
Randomization: The process of assigning trial participants to treatment or control groups using an element of chance to determine the assignments to reduce bias.
Endpoint: The main outcome measured at the end of a study is to see if the treatment has worked (e.g., decrease in symptoms, improvement in quality of life).
Status Meanings:
Not yet recruiting: The study has yet to start recruiting participants.
Recruiting: The study is currently looking for participants.
Enrolling by invitation: The study selects its participants from a particular group.
Active, not recruiting: The study is ongoing but not accepting new participants.
Completed: The study has ended normally, and data are being analyzed.
Suspended: The study has stopped early but may resume.
Withdrawn: The study stopped before enrolling its first participant.
Unknown: The study status is not available.
Pre-Clinical Phase
In the preclinical phase of drug development, which occurs before human trials, the focus is on laboratory research and animal studies to assess safety and biological activity. Key aspects include:
Safety Testing: Determines potential harmful effects and side effects on organs or bodily systems through animal studies.
Dosage Determination: Establishes a safe dosage range and identifies the optimal dose for maximum therapeutic effect.
Drug Formulation: Develop the drug in forms suitable for human use, such as tablets, injections, and stability tests.
Regulatory Approval: Compiles preclinical data to seek approval from regulatory bodies for human clinical trials.
This phase is crucial for ensuring the drug is safe and effective before it is tested in humans.
Phase I
Objective: Test the safety and dosage.
How it Works: The drug or treatment is given to a larger group of people (100-300) with the condition the drug is meant to treat. Researchers measure whether the drug affects the condition and continue to evaluate safety.
Key Point: This phase aims to obtain preliminary data on whether the drug works in people with a certain disease or condition.
Phase II
Objective: Test the effectiveness and further evaluate safety.
How it Works: The drug or treatment is given to a larger group of people (100-300) with the condition the drug is meant to treat. Researchers measure whether the drug affects the condition and continue to evaluate safety.
Key Point: This phase aims to obtain preliminary data on whether the drug works in people with a certain disease or condition.
Phase III
Objective: Confirm effectiveness, monitor side effects, and compare to commonly used treatments.
How it Works: The treatment is given to large groups of people (1,000-3,000). Researchers confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the treatment to be used safely.
Key Point: This phase gathers more information about effectiveness and safety, which is essential for regulatory approval.
Phase IV
Objective: Post-marketing studies delineate additional information, including the drug’s risks, benefits, and optimal use.
How it Works: Conducted after a treatment is approved for use by the FDA or other regulatory agencies. Thousands of participants are involved.
Key Point: These trials gather information on the drug’s effect in various populations and any side effects associated with long-term use.
Join an MDMA, Psilocybin, LSD, or Other Psychedelic Study
Joining a psychedelic clinical trial involves a few key steps. First, you must find a study site in your area and contact them. This can be done by using our search tool. The study site will likely conduct a screening questionnaire to ensure you qualify.
Research Available Trials:
Use Clinical Trial Databases: Search for trials specifically focused on psychedelics.
Check Eligibility Criteria: Each trial has specific requirements, such as age, medical history, or the specific condition being studied. Ensure you meet these criteria before applying.
Contact the Research Team:
Reach Out Directly: Once you find a trial that interests you and fits your profile, contact the research team. Contact information is usually provided on the trial listing.
Undergo Screening: To confirm your eligibility, undergo a thorough screening process, including medical and psychological evaluations.
Understand the Commitments:
Be Aware of Time and Location Requirements: Trials might require regular visits to the study site, which could be time-consuming.
Acknowledge Potential Risks: Understand the potential risks and benefits of the trial. Psychedelic studies can vary greatly in terms of procedures and potential effects.
Informed Consent:
Review and Sign Consent Forms: Before participating, you’ll be asked to sign informed consent forms after the study’s procedures, risks, and benefits have been fully explained to you.
Participation:
Follow the Study Protocol: Once enrolled, adhere to the study’s protocol, which may include taking medications, attending therapy sessions, and providing feedback or data to the research team.
Post-Trial Follow-up:
Attend Follow-up Appointments: Some trials require post-study check-ins to monitor long-term effects.
It’s important to have realistic expectations and understand that clinical trials are conducted primarily for research purposes. The primary goal is to gather data on the safety and efficacy of treatments, not necessarily to provide therapeutic benefit to participants. Always consult with a healthcare professional before considering joining a clinical trial.
What is a Placebo-Controlled Study?
A placebo-controlled study is a type of clinical trial where the effects of a medical treatment are compared with those of a placebo. A placebo is an inactive substance or treatment that looks similar to the tested treatment but has no therapeutic effect.
How Do Placebo-Controlled Studies Work?
Comparison Groups: Participants are divided into two or more groups in these studies. One group receives the experimental treatment, while the other (the control group) receives a placebo.
Blinding: Often, these studies are “blinded,” meaning the participants do not know whether they receive the real treatment or the placebo. This can also be “double-blind,” where neither the participants nor the researchers know who is receiving which treatment to prevent bias.
Measuring Effectiveness: The main purpose is to measure whether the experimental treatment significantly affects the condition more than the placebo.
Why is it Important?
Objectivity: Using placebo controls for the placebo effect, a phenomenon where patients may feel better simply because they believe they are receiving treatment.
Reliability: By comparing the treatment against a placebo, researchers can more accurately determine whether any changes in the participants’ condition are due to the treatment itself and not other factors.
Safety and Efficacy: Placebo-controlled studies are considered the gold standard for testing the safety and efficacy of new treatments. They provide strong evidence for the benefits and risks of new medical interventions.
Potential Pitfalls of Placebo-Controlled Studies
Due to the nature of psychedelic medicine, some research participants may be able to easily tell whether or not they have received the placebo or the active drug. For those who have received a placebo, they may feel less motivated to continue the trial, as they may feel they will not heal or begin to get better. However, the expectations of a positive effect can also negatively impact trial results.
“This effect also works conversely, in that positive expectations can fuel disappointment in trials of novel psychoactive medication when participants believe that they have been allocated to the placebo arm.”
―Matt Butler, Expectancy in placebo-controlled trials of psychedelics
In some cases, participants may be offered the active drug at the end of the trial. Either way, trial participants play a vital role in expanding scientific knowledge and improving health outcomes for future patients.
As a participant, you should keep some key things in mind to help manage your expectations.
Emphasis on Informed Consent: Understand that you may receive either the active treatment or a placebo or an inactive substance, and the purpose of this is to test the effectiveness of the treatment.
Blinding: The study might be blinded, meaning neither you nor the research team will know which group you are in. This helps ensure objective results.
Neutral Expectations: Maintain neutral expectations about the treatment’s effects to avoid bias.
Regular Communication: Contact the research team regularly for any questions or concerns and attend all scheduled check-ins.
Post-Trial Information: After the study, you’ll be informed about which treatment you received and the study results. You may also receive information about further treatment options if necessary.
Placebo-controlled studies are an essential element of modern medical and scientific exploration. These types of studies allow scientists and researchers to develop credible, unbiased data that can serve as the foundation of future medical trials. Often, these studies will be used to determine the efficacy of a new medication and assess safety, tolerance, and other important aspects of a new drug or therapy.
