A Biosimilar Infusion Kept Crohn's and Colitis Under Control in 7 of 10 Patients

Over two years, 72% of people with Crohn's disease and 64% with ulcerative colitis stayed on this infusion treatment. Patients who had switched from the original version did even better — over 80% were still using it two years later. Side effects were similar to the original drug.

What the trial was testing

The REFLECT enrolled 1,431 patients with rheumatoid arthritis. The study was sponsored by Pfizer and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.

What the results showed

After two years, 72% of Crohn's patients and 64% of colitis patients were still successfully using this treatment.

Clinics and research in hepatology and gastroenterology · 2024 · NCT02925338

These findings — that were still successfully using the treatment after two years — were published in the Clinics and research in hepatology and gastroenterology and represent the headline result of the study.

Researchers tracked outcomes across 1,431 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with rheumatoid arthritis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

This infusion is a biosimilar — a nearly identical copy of an established drug — and it worked well for inflammatory bowel disease. If you're already on the original version, switching to this one appears safe and effective. This treatment is FDA-approved and available now. Ask your doctor if it's right for you.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Major Adverse Cardiovascular Events (MACE) in Rheumatoid Arthritis Patient With Moderate to Severe Disease Activity Treated With Tofacitinib and Statins vs TNF Inhibitors: TOFSTAT CLINICAL TRIAL

The rationale of our study is to observe the incidence of MACE in RA patients treated with tofacitinib along with statins with one or more cardiovascular disease risks. PRIMARY OBJECTIVE * To determine the incidence of MACE in Rheumatoid Arthritis patients with moderate to high disease activity and with one or more cardiovascular disease risks, which are non-responsive to standard conventional DMARDs (cDMARDs) treatment and are prescribed Tofacitinib 5 mg twice daily along with statin 20 mg daily versus TNF Inhibitors. * The study aim to compare MACE in RA patients treated with tofacitinib and statin versus TNF inhibitors.

Nerve Conduction Study for Assessment of Peripheral Neuropathy in Rheumatoid Arthritis Patients on the Janus Kinase Inhibitor Baricitinib

Rheumatoid arthritis is a chronic, systemic, autoimmune inflammatory disease that mainly affects the joints and periarticular soft tissues. Baricitinib (Olumiant®) is an oral, targeted synthetic DMARD that inhibits JAK1 and JAK2, which are implicated in the pathogenesis of rheumatoid arthritis (RA). Nerve conduction studies (NCSs) are an essential tool in the evaluation of the peripheral nervous system. The sensory nerve action potential (SNAP) provides information on the sensory nerve axon and its pathway from the distal receptors in the skin to the dorsal root ganglia, while the compound muscle action potential (CMAP) is an assessment of the motor nerve fibers from their origins in the anterior horn cell to their termination along muscle fibers.
