Clinical Study to Investigate Psorax35 Supplementation in Patients With Psoriasis

Randomized, Double Blind, Placebo Controlled Clinical Study to Investigate Efficacy of Psorax35 for Treatment of Psoriasis

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

Study Overview

• Status: Completed
• Conditions: Psoriasis Vulgaris
• Intervention / Treatment: Dietary supplement: Psorax35; Dietary supplement: MCT oil

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Psorax35; Food supplement Psorax35 capsules containing fish roe extract high in eicosapentaenoic acid (EPA)/docosahexaenoic acid (DHA) phospholipid. Dose: 10 capsules of 590 mg. Route of administration: oral.	Dietary supplement: Psorax35; This is a randomized, 32 weeks, single center, placebo controlled, double blind study to investigate Psorax35 supplementation in patients with mild to moderate Psoriasis.
