An Open-label Extension Study to Evaluate the Long-term Safety, Tolerability, and Efficacy of ORKA-001 in Participants with Moderate-to-Severe Plaque Psoriasis
Plaque psoriasis is a long-term condition that causes raised, red, and scaly patches on the skin. This clinical trial is testing a new experimental medicine called ORKA-001 in adults who have moderate-to-severe plaque psoriasis. This is an 'open-label extension' study. 'Open-label' means that both you and the study team know you are receiving the real treatment, with no dummy medicine (placebo). 'Extension' means the trial is designed for people who have already completed an earlier study of ORKA-001, allowing researchers to study its long-term effects. The main aim is to check the ongoing safety of ORKA-001 and see how well the body handles it. Doctors will check for side effects and carry out routine health checks, such as blood tests and heart tracings. They will also track how well the medicine continues to clear skin plaques over many months.
At a glance
What is this study about?
Plaque psoriasis is an immune condition that causes skin cells to grow much faster than normal. This leads to dry, red, raised patches that are often covered in silvery scales. These plaques can be uncomfortable, itchy, and painful. For people with moderate-to-severe psoriasis, standard creams and treatments may not always provide lasting relief, so researchers are looking for new options.
This trial is looking at a new medicine called ORKA-001. It is an extension study, meaning it follows people who took part in a previous trial of the drug to see how it works over a longer period. Everyone in an open-label study receives the active medicine, so there are no dummy treatments or placebos involved.
Doctors want to know whether ORKA-001 remains safe to use over time and whether any unexpected side effects appear. They also want to measure whether it helps participants keep their skin clear. By taking part, volunteers help researchers understand if ORKA-001 could become a reliable, long-term treatment for people living with severe psoriasis in the future.
Key takeaways
- The study tests the long-term safety and effectiveness of ORKA-001 for plaque psoriasis.
- This is an open-label trial, so all participants receive the active study medicine without a placebo.
- It is an extension study, typically meant for people who completed an earlier trial with ORKA-001.
- Participants will have regular health checks, including skin exams, blood tests, and heart monitoring.
- Joining is completely voluntary, and you can withdraw from the study at any time.
Who may be eligible?
This trial is for adults aged 18 and older who have moderate-to-severe plaque psoriasis. Because this is an extension trial, it is generally open to people who have already taken part in an earlier study evaluating ORKA-001.
Both men and women can join. To be suitable, participants must be in good enough general health to take part safely, and they must be willing to attend regular hospital or clinic appointments for check-ups.
You may not be able to join if you have certain other medical conditions, are taking medications that could interfere with the study drug, or are pregnant or breastfeeding. The study team will carry out health checks and go through your medical background to confirm if taking part is right for you.
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.
- I am aged 18 or older.
- I have been diagnosed with moderate-to-severe plaque psoriasis.
- I have previously taken part in an earlier study involving ORKA-001 (or have been invited to continue).
- I am able to attend regular clinic appointments for monitoring and health checks.
- I am willing to follow the study instructions and report any health changes.
What does participation involve?
Taking part involves receiving the study medicine ORKA-001 and attending regular appointments with the research team. At these visits, doctors will examine your skin to measure changes in your psoriasis using standard scoring tools. You will also have routine health checks, such as blood pressure measurements, blood and urine tests, and heart tracings (electrocardiograms, or ECGs) to check your overall wellbeing. The study team will let you know how often you need to visit the clinic and how long your participation will last. You will also be asked to report any side effects or changes in your health between appointments.

Common questions
What does 'open-label' mean?
It means that both you and the research doctors know you are receiving the real study medicine. There is no dummy drug (placebo) used in this trial.
Can anyone with psoriasis join this study?
Generally, extension studies are open to people who have already completed an earlier clinical trial for the same drug. The research team can confirm if you meet the criteria.
Will taking part cure my psoriasis?
Psoriasis currently has no permanent cure. The study medicine aims to manage symptoms and keep skin clear, but it is not expected to permanently cure the condition.
Do I have to pay to take part?
No, the study medication and all trial-related tests are provided free of charge. Some studies also help cover travel expenses to and from the clinic.
What happens if I decide to leave the trial early?
You can leave the study at any point. Your decision will not affect your standard NHS care or your relationship with your regular doctors.
