Filter by:Comparative effectiveness of different drugs used to treat patients in Rheumatoid Arthritis Saudi database (RASD) The goal of this observational study is to compare the effectiveness of different biological Disease Modifying Antirheumatic Drugs (bDMARDs) and targeted synthetic (tsDMARDs) using Disease Activity Score - 28 joints - C-Reactive Protien (DAS-28-CRP) and Clinical Disease Activity Index (CDAI) scores. In rheumatoid arthritis patients in Saudi Arabia who are part of Rheumatoid Arthritis Saudi Database (RASD). The main question[s] it aims to answer: - What is the most effective drug (biologocal or targeted synthetic) disease modifying antirheumatic drug used to treat rheumatoid arthritis in Saudi Arabia? - We are going to use two outcome mesures: Disease Activity Score - 28 joints - C-Reactive Protien (DAS-28-CRP) and Clinical Disease Activity Index (CDAI) scores Researchers will compare the treatment of rheumatoid arthritis using specific outcome measures in Rheumatoid Arthritis in Saudi Arabia. - Participants will be enrolled after a signed written concent in our Rheumatoid Arthritis Saudi Databas (RASD). - Their treatment data will used to compare the effectiveness of different drugs they are using.
ZL-82 is an oral janus kinase (JAK) inhibitor. In vitro biological mass spectrometry identification test proves that ZL-82 can selectively and irreversibly inhibit JAK3. It has obvious safety advantages, with a wide therapeutic window and controllable cardiotoxicity. This is also demonstrated from preliminary GLP-conditions of acute toxicity in SD rats and Beagle dogs. Results of 4-week long-term toxicity in Beagle dogs also support this notion. Therefore, ZL-82 has the potential to treat rheumatoid arthritis. It Used to relieve and heal swelling, pain, stiffness, and limited mobility that may be caused by rheumatoid arthritis.The drug is intended to be used in patients with RA to relieve and heal swelling, pain, stiffness, and limited mobility that may be caused by rheumatoid arthritis. Pharmacodynamic studies show that ZL-82 has a strong inhibitory effect on JAK3 with IC50 of 2.8 nM, and has no obvious inhibitory effect on JAK1, JAK2 and TYK2. Compared with the similar drug Tofacitinib, its inhibitory effect on JAK3 subtype is 1nM, but its inhibition IC50 for JAK1 subtype and JAK2 subtype are 112nM and 20nM, respectively.and its selectivity is 100-fold and 20-fold, respectively.Also, the selectivity multiples of ZL-82 were 100-fold and 20-fold than tofacitinib , respectively, which indicates that ZL-82 is more selective than the marketed Tofacitinib.This allows ZL-82 to precisely inhibit JAK kinase and block a series of cytokines in the downstream signaling pathway. And show significant effect on rheumatoid arthritis. The experimental results showed that in DTH and CIA models, 25, 50, 75, and 100 mg/kg of this variety could dose-dependently inhibit joint swelling in mice. Objectives of Study Main Purpose: 1. To evaluate the tolerability, safety and pharmacokinetic characteristics of a single oral dose of ZL-82 tablets in healthy adult subjects; 2. To explore the effect of eating on the PK of oral ZL-82 tablets in healthy adult subjects; 3. To evaluate the tolerability, safety and pharmacokinetics of ZL-82 tablets after multiple oral administration in healthy adult subjects.
Rheumatoid arthritis (RA) is known as a long-lasting inflammatory autoimmune disease affecting the diarthrodial joints, which is diagnosed by inflammation and hyperplasia in synovium, generation of RF and anti-citrullinated protein antibody (ACPA), deformity of cartilage and bone, systemic injuries involving cardiovascular, pulmonary, psychological, and skeletal disorders (McInnes and Schett., 2011).
Rheumatoid Arthritis (RA) is an inflammatory disease of the joints characterized by the swelling of multiple joints and tenderness caused by progressive inflammatory synovitis, which leads to serious and debilitating diseases. Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Ankylosing Spondylitis (AS) is a form of chronic arthritis causing inflammation in the spine. This can cause pain and stiffness in the back. Psoriatic arthritis (PsA) is a type of arthritis (swelling and stiffness in the joints) that is frequently seen in trial participants who also have the skin condition psoriasis. It is caused by the body's immune system mistakenly attacking healthy joint tissue causing inflammation, joint damage, disability, and a reduced life expectancy. This study will assess the adverse events and change in disease symptoms in Korean participants with RA, AD, AS or PsA. Upadacitinib is a drug approved for the treatment of moderately to severely active rheumatoid arthritis, atopic dermatitis, ankylosing spondylitis or psoriatic arthritis. Korean participants who have been prescribed upadacitinib by their physicians will be enrolled. Approximately, 3600 participants will be enrolled this study, in multiple sites within Korea. Participants will receive Upadacitinib as prescribed by the physician and will be followed for approximately 28 weeks. There will be no additional burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic and will be asked to provide additional information by questionnaire at each visit.
Rheumatoid Arthritis (RA) is a chronic inflammatory disease causing pain, stiffness, swelling and loss of joint function. RA can reduce the ability to perform everyday tasks. The purpose of this study is to observe the incidence of serious infections, regardless of their relationship to RINVOQ, in Japanese daily practice. RINVOQ is an approved drug for the treatment of adults with moderately to severely active RA. This study evaluates medical records from institutions participating in the study to identify any adverse events (untoward medical occurrence), and reasons for discontinuation of RINVOQ in participants taking the study drug. A target of 1000 Japanese participants' data will be observed for 3 years. Participants will receive RINVOQ per their physicians' usual prescription. Individual data will be collected for three years. No additional study-related tests will be conducted during routine clinic visits. Only data which are routinely collected during clinic visits will be utilized for this study.
- To demonstrate that SM03 added to methotrexate (MTX) reduce signs and symptoms of rheumatoid arthritis (RA) in Chinese RA participants with an inadequate response to MTX. - To assess the safety of SM03 added to MTX in Chinese RA participants with an inadequate response to MTX
The objective of this study is to investigate the safety and effectiveness in routine clinical practice and actual clinical setting for all patients with rheumatoid arthritis (RA) treated with peficitinib.
The goal of treating patients diagnosed with rheumatoid arthritis (RA) is to achieve remission or low disease activity and thereby prevent joint damage, loss of physical function, and disability. Optimal management requires regular assessment of disease activity, with treatment changes made as needed for optimal efficacy. Vectra is a blood serum test that looks at 12 biomarkers and produces a score on a scale of 1 to 100. The Vectra score has been shown to be the strongest predictor of risk for progression of disease. There is opportunity to gain more information about the utility of Vectra in a real-world clinical setting. This study will, therefore, evaluate the utility of Vectra for guiding treatment decisions and improving RA-related outcomes in comparison with usual care, which will not include Vectra testing. This study will enable a direct evaluation of the clinical benefit associated with using Vectra to guide treatment decisions in patients with RA.
The primary objective of this study is to demonstrate superior efficacy of abatacept 125mg administrated SC weekly comparing to placebo after 24 weeks treatment in Chinese subjects who have active rheumatoid arthritis, are receiving methotrexate and experiencing an inadequate response to methotrexate. This will be estimated by the proportion of subjects meeting the American College of Rheumatology (ACR) criteria for 20% improvement (ACR20).
This is a Rheumatoid Arthritis (RA) study. The purpose of this research study is to determine in RA flare, whether musculoskeletal ultrasound (MSUS) inflammatory scores and/or disease activity scores improve with Acthar treatment.
