Brief Summary

This is a multicenter, randomized, double-blinded，controlled clinical trial. The purpose of the study is to evaluate the efficacy and safety of Sulodexide versus placebo in preventing psoriasis recurrence in patients with plaque psoriasis who have discontinued biologic therapy after achieving clinical cure.

Detailed Description

It was planned to include 160 patients with psoriasis vulgaris who met the inclusion criteria for discontinuation of biologics after reaching the standard of treatment and were randomised in a 1:1 ratio to receive oral treatment with sulodexide soft capsules or placebo capsules, respectively.

1. Sulodexide group： Starting after the last injection of secukinumab, oral treatment with sulodexide soft capsule (Alpha Weissmann Pharmaceuticals, Italy, approval number H20140119, specification 250 LSU) was given as 1 tab bid for 120 days or discontinued after judged to be a relapse;

2. Control group: Oral treatment with placebo capsule, 1 tab bid starting after the last injection of secukinumab, discontinued after 120 days of continuous oral administration or judged to be discontinued for relapse.

Conditions

Psoriasis (PsO); Randomised Controlled Trial

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: PREVENTION
• Blinding Strategy: QUADRUPLE

Study Groups

Sulodexide Group

Participants in this group will receive oral sulodexide soft capsules (manufactured by Alfa Wassermann, Italy; approval number H20140119, specification 250 LSU) after discontinuing secukinumab. The dosing regimen is 1 capsule twice daily for 120 consecutive days or until psoriasis relapse is confirmed. Sulodexide, a vascular protective agent, aims to prolong psoriasis recurrence by improving vascular endothelial barrier function. During the study, disease relapse (assessed via PASI scores) and safety indicators (e.g., adverse events, laboratory tests) will be regularly monitored.

Group Type: EXPERIMENTAL

Sulodexide

Intervention Type: DRUG

Sulodexide group：Starting after the last injection of secukinumab, oral treatment with sulodexide soft capsule (Alpha Weissmann Pharmaceuticals, Italy, approval number H20140119, specification 250 LSU) was given as 1 tab bid for 120 days or discontinued after judged to be a relapse.

Placebo Comparator Group

Participants in this group will receive matching placebo capsules orally after discontinuing secukinumab. The dosing regimen is 1 capsule twice daily for 120 consecutive days or until psoriasis relapse is confirmed. The placebo capsules are identical in appearance and packaging to the active sulodexide capsules but contain no active pharmaceutical ingredients. This group serves as a control to evaluate the efficacy of sulodexide in delaying psoriasis recurrence. Disease relapse (assessed via PASIscores) and safety indicators (e.g., adverse events, laboratory tests) will be monitored at the same intervals as the experimental group.

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: DRUG

Control group: Oral treatment with placebo capsule, 1 tab bid starting after the last injection of secukinumab, discontinued after 120 days of continuous oral administration or judged to be discontinued for relapse.

Interventions

Sulodexide

Sulodexide group：Starting after the last injection of secukinumab, oral treatment with sulodexide soft capsule (Alpha Weissmann Pharmaceuticals, Italy, approval number H20140119, specification 250 LSU) was given as 1 tab bid for 120 days or discontinued after judged to be a relapse.

Intervention Type: DRUG

Placebo

Control group: Oral treatment with placebo capsule, 1 tab bid starting after the last injection of secukinumab, discontinued after 120 days of continuous oral administration or judged to be discontinued for relapse.

Intervention Type: DRUG

Other Intervention Names
