In vivo bioequivalence study of a new clobetasol propionate 0.05% topical cream compared to DERMOVAL® 0.05% cream using the skin blanching bioassay in healthy subjects.
This research is looking at a new cream that contains the same medicine as Dermoval (clobetasol propionate 0.05%). Dermoval is a strong cream used to treat skin problems like eczema and psoriasis. The main goal of this study is to compare the new cream to Dermoval to make sure they work in the same way. We call this a 'bioequivalence' study. Healthy adults will take part, and we will apply the creams to a small area of their skin. We'll then look at how their skin changes, specifically how much it lightens or 'blanches', to understand how well the cream is absorbed and how strong its effect is. This helps make sure new medicines are safe and effective.
At a glance
What is this study about?
You might be familiar with skin conditions like eczema or psoriasis, which can cause red, itchy, or flaky patches. Doctors often treat these with steroid creams, which help to reduce inflammation and discomfort. Dermoval is one such strong steroid cream. Before a new version of a cream like Dermoval can be used more widely, scientists need to make sure it's just as effective and safe as the original. This is where our study comes in.
This study is comparing a new cream that contains the identical medicine to Dermoval. We call this a 'bioequivalence' study – it simply means we're checking if two versions of the same medicine work in the same way in the body. If they do, then the new cream can be considered a reliable alternative to the original.
To do this, we'll ask healthy volunteers to apply small amounts of the creams to their skin. We will then carefully observe how the skin changes, particularly looking at how much it 'blanches' or lightens. This blanching effect is a common way to measure how effectively a steroid cream is absorbed into the skin and how strong its anti-inflammatory action is. By comparing the new cream's effect to Dermoval's, we can confidently say if they are equally effective.
Key takeaways
- This study compares a new skin cream to an existing one (Dermoval).
- It aims to confirm both creams work in the same way (bioequivalence).
- Healthy adult volunteers, aged 18 and over, are needed.
- Participation involves applying creams to small skin areas and having them checked.
- The study helps ensure new medicines are safe and effective.
- You can withdraw from the study at any time.
Who may be eligible?
This study is looking for healthy adult volunteers. You need to be at least 18 years old to take part. There is no upper age limit, so adults of all ages are welcome.
Both men and women can join this study. The most important thing is that you are generally healthy.
If you have any current skin conditions or are using other medicines, it's very important to let the study team know. They will check if the study is right for you, especially if you have a skin condition that might affect the results.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Are you generally healthy?
- Do you not have any active skin conditions on the areas where cream would be applied?
- Are you able to attend clinic visits as required?
- Are you comfortable with creams being applied to your skin for testing?
What does participation involve?
If you decide to take part, you will be given small amounts of the new cream and Dermoval to apply to specific, small areas of your skin. These will be carefully marked out. You will likely visit the study clinic several times for the cream to be applied and for your skin to be checked.
During each visit, the study team will examine your skin to see how it's reacting to the creams. They will be looking for the 'blanching' effect, which tells them how well the medicine is working. These assessments might involve visual checks and possibly some measurements.
Typically, a study like this involves a few visits over a short period, perhaps a few days or weeks. You won't need to take any medicine internally, only apply the creams to your skin. The total time you'd spend on the study, from first visit to last check-up, will be explained fully by the study team.

Common questions
What is 'bioequivalence'?
It means we're comparing two versions of the same medicine to see if they work in the exact same way in your body.
What is 'skin blanching'?
It's when the skin temporarily lightens or looks paler because a steroid cream has been applied and is working. It's a way to measure how strong the cream is.
Will I get paid to take part?
The study team can tell you if there is any compensation for your time and travel expenses for taking part.
How long will I be involved?
The study team will explain the exact number of visits and the total duration, but bioequivalence studies are often short, lasting a few weeks at most.
Do I need to have a skin condition to join?
No, this study is looking for healthy volunteers. We are not treating a skin condition, but rather testing how the creams affect healthy skin.
