Objectives
The primary objective of this study is to evaluate the effect of **Baricitinib** on the inflammation of the synovial membrane in patients with calcium pyrophosphate deposition disease (CPPD). This is clinically relevant as it aims to measure changes in the synovial tissue CD68 scoring at 12 weeks, providing an objective outcome measure for assessing the therapeutic impact of Baricitinib on synovial inflammation.
Secondary objectives include:
- Assessing changes in the Krenn synovitis score and cytokines at the synovial level.
- Evaluating the improvement of patient-reported outcomes (PROs) and pain.
- Determining changes at ultrasound examination in terms of calcium crystal deposition, synovitis, and degenerative changes.
- Identifying subsets of the disease that could have a better response to the treatment.
- Evaluating the effect of Baricitinib on serum cytokine levels at a plasmatic level.
- Exploring the possible Baricitinib-induced impact on whole-body metabolism.
- Exploring differences in biochemical and immunohistological markers between patients with the acute and the chronic form of CPPD.
Participants
The clinical trial focuses on evaluating the effect of Baricitinib on inflammation of the synovial membrane in patients with **calcium pyrophosphate deposition disease** (CPPD). The study population includes both male and female participants aged 55 years and older. Participants are required to be in general good health, with specific inclusion criteria such as fulfilling the 2023 ACR/EULAR classification criteria for CPPD disease and having the feasibility of synovial biopsy at the knee or wrist joint. The trial does not involve a vulnerable population. Lifestyle considerations include the requirement for male participants to avoid fathering a child during the trial, using highly effective contraception methods or maintaining sexual abstinence. The sponsor has not provided information regarding the total number of participants in the trial.
Plans and Procedures
The clinical trial is designed to evaluate the effect of **Baricitinib** on inflammation of the synovial membrane in patients with calcium pyrophosphate deposition disease (CPPD). This is a randomized, double-blind, controlled trial with a primary objective to assess changes in synovial tissue CD68 scoring at 12 weeks. The trial is expected to last until October 2026, with recruitment starting in November 2024. Participants will be involved for a maximum of 24 weeks, with the possibility of early termination if they do not adhere to the study protocol or if adverse events occur that compromise their safety.
Study visits are structured to ensure comprehensive data collection and participant safety. The inclusion visit, or screening, will confirm eligibility based on criteria such as age, gender, and specific disease characteristics. Follow-up visits will occur at 4, 12, and 24 weeks to monitor changes in synovial inflammation, as well as secondary endpoints like Krenn synovitis score, DAS, HAQ score, WOMAC, and serum cytokine levels. The end-of-study visit will conclude the participant's involvement, ensuring all data is collected and any necessary post-trial care is arranged.
Participants will be randomly assigned to receive either the investigational product or a comparator, with all medications administered orally. The trial will include several medicinal products, such as **Methotrexate Sodium**, **Colchicine**, **Calcium Folinate**, **Hydroxychloroquine Sulfate**, and **Lidocaine Hydrochloride Monohydrate**, each with specific roles and dosage limits. The trial's design ensures that neither the participants nor the investigators know which treatment is being administered, maintaining the double-blind nature of the study.
Inclusion criteria require participants to be 55 years or older, with a confirmed diagnosis of CPPD and the feasibility of synovial biopsy. Exclusion criteria are not explicitly detailed but would typically include conditions that could interfere with the study's objectives or participant safety. The trial's methodology and design are structured to provide robust data on the efficacy and safety of Baricitinib in treating CPPD, contributing valuable insights into potential therapeutic options for this condition.
Treatment
The clinical trial involves the administration of several **experimental medications** and comparator treatments. The primary experimental medication is **Baricitinib**, marketed as Olumiant, which is provided in the form of 4 mg film-coated tablets. The maximum daily dose is 4 mg, with a total maximum dose of 672 mg over a 24-week period. Baricitinib is administered orally and functions as an immunosuppressant. The medication is used to evaluate its effect on inflammation of the synovial membrane in patients with calcium pyrophosphate dihydrate deposition disease (CPPD).
**Methotrexate Sodium** is included as a comparator treatment. It is administered orally in a pharmaceutical form identified as PHF00231MIG. The maximum daily dose is 10 mg, with a total maximum dose of 240 mg over the 24-week treatment period. Methotrexate Sodium acts as an antineoplastic antimetabolite.
Another comparator treatment is **Colchicine**, combined with Tiemonium Methylsulphate, provided in the pharmaceutical form PHF00082MIG. The maximum daily dose for Colchicine is 1 mg, with a total maximum dose of 168 mg over the 24-week period. This combination is administered orally and serves as an anti-inflammatory agent.
**Calcium Folinate**, also known as Leucovorin Calcium, is administered orally in the form PHF00169MIG. The maximum daily dose is 5 mg, with a total maximum dose of 120 mg over the 24-week period. Calcium Folinate functions as an antianemic agent and is used as a comparator treatment.
**Hydroxychloroquine Sulfate** is another comparator treatment, administered orally in the form PHF00082MIG. The maximum daily dose is 200 mg, with a total maximum dose of 33,600 mg over the 24-week period. Hydroxychloroquine Sulfate is classified as an antimalarial.
Lastly, **Lidocaine Hydrochloride Monohydrate** is included as a comparator treatment, administered orally in the form PHF00243MIG. The maximum daily dose is 16 mg, with a total maximum dose of 2,688 mg over the 24-week period. Lidocaine Hydrochloride Monohydrate is categorized under corticosteroids.
All medications are administered orally, and participant compliance is monitored throughout the trial. The trial aims to assess the efficacy and safety of Baricitinib in comparison to these established treatments in managing inflammation associated with CPPD.
Efficacy
Efficacy in this clinical trial will be assessed through a series of primary and secondary endpoints. The primary endpoint is the change from baseline in **CD68** scoring at 12 weeks, which serves as an objective measure of the effect of Baricitinib on inflammation of the synovial membrane in Calcium Pyrophosphate Dihydrate Deposition Disease (CPPD). Secondary endpoints include changes from baseline in the Krenn synovitis score, CD3, CD8, and CD20 at the synovial level at 12 weeks. Additionally, changes in Disease Activity Score (DAS), Health Assessment Questionnaire (HAQ) score, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) will be evaluated at 4, 12, and 24 weeks.
Further secondary endpoints involve the assessment of changes from baseline in Musculoskeletal Ultrasound (MSUS) EULAR-OMERACT synovitis score, CPP deposition extent according to the OMERACT CPPD scoring system, and degenerative changes at 4, 12, and 24 weeks. Serum cytokine levels, including IL-1, IL-6, IL-8, anti-TNFα, Interferon α and γ, and TGF-β, will be measured at 12 and 24 weeks. The visual analog scale (VAS) for pain will also be assessed at 4, 12, and 24 weeks. These efficacy parameters will be collected and analyzed at specified timepoints to determine the therapeutic impact of the investigational product.
