Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Signed informed consent by participants from previous trial choosing to transition into the OLE.
- Participants who have successfully completed the preceding trial.
- For women of childbearing potential, must have a negative urine pregnancy test at Baseline visit.
- For women of childbearing potential and fertile male participants with a partner of childbearing potential must be willing to continue to use highly effective contraception
Exclusion criteria
- Participants who experienced any adverse events with ORKA-001 in the preceding trial that led to permanent investigational medicinal product discontinuation or, in the opinion of the Investigator, would preclude continued treatment with ORKA-001
- Participants who have developed guttate, erythrodermic or pustular psoriasis or drug-induced psoriasis (as diagnosed by the Investigator), during the preceding trial.
- Evidence of current or previous clinically significant disease, medical condition other than psoriasis, or finding during the medical examination that, in the opinion of the Investigator would compromise the safety of the participant or the quality of the data.
- Any clinically significant laboratory abnormality based on the last available lab results received during the preceding trial, that, according to the Investigator's medical assessment, precludes them from continued treatment with ORKA-001.
- Participant is pregnant or breastfeeding.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
