Parkinson’s disease is a complex disorder that affects millions of people worldwide. While current treatments can help manage symptoms, there is still no cure for the disease. As a result, researchers and pharmaceutical companies are constantly working on developing new therapies to slow or stop the progression of Parkinson’s disease.1,2
Researchers use clinical trials to test the safety and efficacy of new treatments for Parkinson’s and other diseases. These trials involve human participants who agree to test experimental treatments or therapies. Clinical trials are essential for advancing medical knowledge and improving patient care for Parkinson’s disease.

Developments in Parkinson’s Disease Research and Clinical Trials
While there is no cure for Parkinson’s disease, researchers are constantly working on developing new treatments and therapies. Currently, there are a number of clinical trials underway for Parkinson’s disease that are testing a range of treatments, including gene therapy, stem cell therapy, and new drugs. These treatments are aimed at reducing the symptoms of Parkinson’s disease and potentially stopping or slowing its progression. The trials involve people from different backgrounds and with different stages of the disease.3
Gene Therapy for Parkinson’s Disease
One of the most exciting areas of development in Parkinson’s disease research is the use of gene therapy. Gene therapy involves altering the DNA (genetic material) of cells to prevent or treat disease.
In Parkinson’s disease, researchers are testing the use of gene therapy to deliver a gene that produces a protein called GDNF, which protects and regenerates dopamine-producing cells in the brain. This therapy has shown promise in early clinical trials, and researchers are continuing to study its safety and effectiveness.
Dopamine Receptor Agonists for Parkinson’s Disease
One of the main therapies for Parkinson’s disease is dopamine receptor agonists. These drugs mimic the function of dopamine in the brain by activating certain receptors called D1 and D2. However, with prolonged use, the effectiveness of these drugs may decrease.
Recently, six clinical trials have been conducted using four small molecule drugs that act as dopamine receptor agonists.
Anti-α-Synuclein Aggregation Therapy for Parkinson’s Disease
Scientists are exploring a new way to treat Parkinson’s disease called anti-α-synuclein aggregation therapy. This approach involves developing drugs that target a protein called α-synuclein, which is believed to be involved in the development of Parkinson’s disease. These drugs are designed to reduce the amount of α-synuclein in the brain, which may slow or halt the progression of the disease.
Currently, there are five clinical trials underway that are testing different treatments using monoclonal antibodies, vaccines, and small molecules that target α-synuclein. These trials are looking to see if these treatments can reduce the accumulation of α-synuclein in the brain and improve symptoms of Parkinson’s disease.
Conventional Drug Development for Parkinson’s Disease
In addition to gene therapy and stem cell therapy, researchers are also testing new drugs for Parkinson’s disease. These drugs aim to improve symptoms such as tremors, rigidity, and difficulty with movement. One of the most promising drugs in development is a molecule called ISRIB, which has shown promise in reducing toxic protein clumps in the brain that are associated with Parkinson’s disease.
Criteria for Current Parkinson’s Disease Clinical Trials

Parkinson’s disease clinical trials have criteria to ensure that the participants are appropriate for the study and that the results are accurate. Here are some of the criteria that current Parkinson’s disease clinical trials may have, though each study is different:
Age and Gender
Some clinical trials may require participants of a certain age range or gender. For example, a trial may only include participants who are 50 years of age or older.
Stage of Parkinson’s Disease
Different clinical trials may be looking for participants at different stages of Parkinson’s disease. Some trials may only include participants who have been recently diagnosed, while others may be looking for participants with more advanced Parkinson’s disease.
Some trials may require participants to have never received treatment for Parkinson’s disease, while others may only include participants who have not responded well to other treatments.
Some trials may be looking for participants with certain genetic mutations or markers that are associated with Parkinson’s disease.
Clinical trials may have specific requirements for a participant’s overall health, such as blood pressure, heart function, and other factors.
Some trials may be available only in certain geographic areas, such as specific cities or regions.
Participating in clinical trials is an important way to contribute to Parkinson’s disease research and potentially benefit from new treatments or therapies.
If you are found to be eligible for the trial, you will go through a screening process to ensure that you meet the trial’s specific criteria. This may involve physical exams, blood tests, and other assessments.
Clinical trials are essential for Parkinson’s disease research and offer hope for new and effective treatments for the disease. If you’re interested in participating in a clinical trial, talk to your doctor and do your research to find a trial that may be a good fit for you. Understanding the eligibility criteria and potential risks and benefits is crucial before making a decision to participate.
