Study summary

The main objective of this study is to establish the efficacy and safety of Psorax35 supplementation in patients with mild to moderate Psoriasis.

Read the detailed description

Psoriasis is a common, genetically predisposed, inflammatory and proliferative disease of the skin, the most characteristic lesions consisting of chronic, sharply demarcated, dull-red scaly plaques, particularly on extensor parts of limbs and in the scalp. Psoriasis can be divided into mild, moderate or severe psoriasis based on the extent of the skin changes

Psorax35, which is extracted from herring roe are shown to improve the condition of people with psoriasis.

The objective of this study is to investigate the effect, safety, and mechanism of action of Psorax35 on mild to moderate Psoriasis and comorbidities associated with psoriasis through a 32-weeks study.

The participants will be randomized into one of two arms; Psorax35 and Placebo. The study will include a total of 6 treatment visits involving Blood samples, Photo documentation, Psoriasis and Severity index (PASI), Body surface area (BSA), Physician's Static Global Assessment (PSGA), Life quality index (EQ-5D, VAS and DLQI), Blood pressure, Blood rate, Body Mass Index (BMI), Waist circumference, Waist/hip ratio, and 24 hrs dietary recall. At visit 4 Blood samples, Blood pressure, Blood rate, BMI, Waist circumference, Waist/hip ratio, and 24 hrs dietary recall are not included.

    • PASI scores less than 10 (mild psoriasis) and
    • Body surface area affected by chronic plaque psoriasis 1%-9.9% (mild and moderate psoriasis)
  3. Women of must have a negative serum pregnancy test at the screening visit.

Exclusion criteria

Exclusion Criteria:

  1. Pregnancy
  2. Initiation of a drug known to cause or exacerbate psoriasis
  3. Having received an medical product (IMP) or investigational device within 28 days' prior randomization
  4. Alcohol and drug abuse or any condition associated with poor compliance
  5. Malabsorption disorder
  6. Scheduled hospitalization during the course of the study that could compromise the study
  7. Major diseases or infections
  8. Known or suspected sensitivity or allergic reactions to the IMP or
  9. Presence of other major medical or psychiatric illness that would affect the ability to participate in the study or put the subject at increased risk
  10. Planned trip abroad to a sunny resort involving active sun exposure
  11. Any anti psoriatic treatment
  12. - immunomodulating treatment given for any other reason than psoriasis
  13. UV treatment and return from a sunny resort involving active sun exposure for the last 4-6 weeks
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
