If you have diabetes, you probably worry about the health of your eyes. Your doctor may have told you that diabetes affects your eyes, a condition called Diabetic Macular Edema (DME). So, when it comes to treating this condition, have you ever heard of a ‘clinical trial’? Hearing this name can be a bit scary. You might be thinking, “Am I being tested?” But it’s not something to be afraid of. Today, let’s talk about what it really is, what benefits it can bring you, and whether it’s right for you.
Simply put, what is a clinical trial?
Think about any medicine you buy from the pharmacy. From the medicine for fever and cough to the medicine for your diabetes and blood pressure, everything undergoes rigorous testing before it reaches your hands. That testing is what we call a `Clinical Trial`.
Simply put, this is the process of testing a new drug before giving it to people to see if it really works (effective) and is safe to use (safe) . This is done in a very planned manner, under the strict supervision of doctors and researchers. For this, a group of patients who volunteer to be given this new treatment and their condition is monitored very closely. So this is not like being a "guinea pig" at all. This is done under very formal, ethical rules, and with patient safety as a priority.
Only after successfully passing such tests, institutions like the National Medicines Regulatory Authority (NMRA) of Sri Lanka grant permission for the drug to be used in the country.
What are the benefits of a clinical trial for someone with DME?
You might be thinking, "Okay, that's it, but why am I getting involved in this? What's the benefit to me?" There are actually several benefits. Let's take a look at them.
| Benefit | This means... |
|---|---|
| Access to cutting-edge treatments | You'll have the opportunity to try a new treatment that hasn't hit the mainstream market yet. It could be a medication that your doctor can't usually prescribe. |
| Ability to get better results | Sometimes these new treatments may be more effective than existing treatments, meaning your vision may improve or your condition may be controlled more quickly. |
| Very close medical supervision | You will receive more attention and supervision than you would normally receive when you go to a clinic. You will be tested frequently, and the doctors will constantly check on your condition. |
| Helping the future | By getting involved, you are contributing to increasing scientific understanding of DME and helping to provide better treatments for others with this disease in the future. |
What are the researchers' goals?
There are several main goals of current research on DME.
- Reducing the number of clinic visits: Imagine how much easier it would be if you didn't have to go to the hospital so often to get eye injections. Researchers are trying to find drugs that last longer.
- Pills instead of injections: Some people find it difficult to get injections into the eye. What if this disease could be controlled with a pill taken daily instead? This is another big area of research.
- Increasing the effectiveness of treatment: Another goal is to find drugs that are better and more effective than existing drugs.
How does a clinical trial work?
These trials can be divided into two main types. But let's talk about the most common type. It's called an `Interventional Trial`.
This involves researchers giving a treatment (such as a medicine or an injection) and studying its effects. This can be done in a variety of ways.
But most often, a method called a 'Randomized Controlled Trial' is used. Although the name is a bit complicated, the concept is simple.
Imagine that 100 people volunteered for this test.
1. Division into groups: These 100 people are randomly divided into two groups of 50 people each, without any selection.
2. Providing treatment:
- The first group (50 people): will be given the newly tested treatment.
- The second group (the other 50): will continue to receive the best, standard treatment currently used for DME. This group is called the `Control Group`.
3. Comparison: After a certain period of time, the results of both groups are compared. How much better is the new treatment than the old treatment? Does it have fewer side effects? Is it safe? Everything can be measured accurately through this.
Without comparing it to a control group in this way, it is impossible to scientifically prove how effective a new drug really is. That is why this method is so important.
How do I get involved in something like this?
This is the most important question. If you are interested in this, the first and most important step you should take is to talk to your eye surgeon or diabetes doctor who is treating you.
- Your doctor knows your medical condition and health history best, so he or she can give you the best advice on whether or not it is appropriate for you to participate in such a test.
- Such studies are regularly conducted in large government hospitals in Sri Lanka, especially those affiliated with medical faculties. Your doctor will be able to find out if there is a test currently being conducted that is suitable for you and refer you for it.
- Never make decisions like this on your own without consulting your doctor.
Before you participate, the team in charge of the study will explain everything to you (what will be done, the possible risks, the benefits). Your written consent will be obtained only after you have asked any questions and are fully satisfied. Also, if you feel uncomfortable at any time during the study, you have the full right to withdraw from it.
Take-Home Message
- A clinical trial is a formal study conducted to confirm the safety and effectiveness of a new drug before it is given to people.
- By participating in a trial like this, you, who have DME, have the opportunity to receive the latest treatments that are currently unavailable and receive better medical supervision.
- This is a great help to you and others who may suffer from this disease in the future.
- If you are interested in this, first and foremost, talk to your doctor and seek his advice.
