A Study of Picankibart in Patients With Active Psoriatic Arthritis

March 18, 2026 updated by: Innovent Biopharmaceutical Technology (Hangzhou) Co., LTD.

A Multicenter, Randomized, Double-blind, Placebo-controlled Phase II/III Clinical Study to Evaluate the Efficacy and Safety of Picankibart in Patients With Active Psoriatic Arthritis

This is a multicenter, randomized, double-blind, placebo-controlled Phase II/III clinical trial evaluating the efficacy and safety of picankibart (IBI112) in patients with active psoriatic arthritis (PsA). The study consists of two stages: Phase II dose-finding (n=90) and Phase III confirmatory (n=132). Participants will receive subcutaneous (SC) injections of either picankibart (200mg) or placebo with different dosing schedules, with placebo crossover to active treatment at Week 26. The Phase II portion will identify optimal dosing for Phase III, which will confirm efficacy. The study will evaluate improvements in joint symptoms, physical function, quality of life, and skin manifestations. Primary endpoint is percentage of participants who achieved an American College of Rheumatology (ACR) 20 Response at Week 24.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of participants who achieved an American College of Rheumatology (ACR) 20 response
Time Frame: Week 26
The ACR20 response is defined as ≥20% improvement in swollen joint count (66 joints) and tender joint count (68 joints) and ≥20% improvement in 3 of following 5 assessments: participant's assessment of pain using Visual Analog Scale (VAS; 0-100 millimeter [mm], 0 mm=no pain and 100 mm=worst possible pain), participant's global assessment of disease activity by using VAS (scale ranges from 0 mm to 100 mm, [0 mm= very well to 100 mm= very poor]), physician's global assessment of disease activity using VAS (scale ranges from 0 to 100), [0 = no arthritis to 100 = extremely active arthritis], participant's assessment of physical function measured by Health Assessment Questionnaire-Disability Index (HAQ-DI, defined as a 20-question instrument assessing 8 functional areas. The derived HAQ-DI ranges from 0, indicating no difficulty, to 3, indicating inability to perform a task in that area) and C-reactive protein (CRP).
Week 26

Secondary Outcome Measures

Secondary Outcome Measures

Week 26, and from baseline to Week 56
Change from baseline in Short Form Health Survey 36 (SF-36) Physical Component Summary (PCS) score
Time Frame: Week 26, and from baseline to Week 56
The SF-36 Health determined participants' overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 1-4 comprise the physical component of the SF-36. Scores on each item were summed and averaged (range = 0-100) and a positive change from Baseline indicates improvement.
Week 26, and from baseline to Week 56
Enthesitis/dactylitis resolution rates
Time Frame: Week 26, and from baseline to Week 56

An SAE is an AE that results in death, is life-threatening, results in or prolongs hospitalization, results in congenital anomaly, persistent or significant disability/incapacity, spontaneous or elective abortion, or requires intervention to prevent a serious outcome.
From baseline to Week 56
Maximum plasma concentration (Cmax) of picankibart
Time Frame: From baseline to Week 56
Plasma concentration of picankibart is evaluated at each scheduled dosing timepoint. Cmax is the highest concentration of a drug in the blood.

Area under the concentration-time curve (AUC) of picankibart
Time Frame: From baseline to Week 56
Plasma concentration of picankibart is evaluated at each scheduled dosing timepoint. AUC represents the area under the concentration-time curve and gives insight into the extent of exposure to a drug and its clearance rate from the body.
From baseline to Week 56
Percentage of participants who developed anti-drug antibody (ADA)
Time Frame: From baseline to Week 56
ADAs are immune system-produced antibodies that specifically bind to therapeutic drugs, potentially altering their pharmacokinetics, efficacy, or safety.
From baseline to Week 56
Percentage of participants who developed neutralizing antibody (NAb)
Time Frame: From baseline to Week 56
NAbs are ADAs that inhibit the drug's biological function by blocking target interaction.
From baseline to Week 56
