Phase 2 trial: Baricitinib for systemic lupus erythematosus

Baricitinib is an oral selective Janus kinase (JAK)1 and JAK2 inhibitor that we hypothesised might have therapeutic benefit in patients with systemic lupus erythematosus.

In a double-blind, randomised, placebo-controlled, 24-week phase 2 study, patients were recruited from 78 centres in 11 countries. Eligible patients were aged 18 years or older, had a diagnosis of systemic lupus erythematosus, and had active disease involving skin or joints.

European Commission (EC) has approved XELJANZ® (tofacitinib citrate) 5 mg twice daily (BID) in combination with methotrexate (MTX) for the treatment of active psoriatic arthritis

Pfizer Inc. (NYSE:PFE) announced today that the European Commission (EC) has approved XELJANZ® (tofacitinib citrate) 5 mg twice daily (BID) in combination with methotrexate (MTX) for the treatment of active psoriatic arthritis (PsA) in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug (DMARD) therapy.1 XELJANZ is the first and only oral Janus kinase (JAK) inhibitor to be approved in the European Union (EU) for the treatment of adults with active PsA. In 2017, XELJANZ in combination with MTX was approved in the EU for the treatment of moderate to severe active rheumatoid arthritis in adult patients who have responded inadequately to, or who are intolerant to one or more DMARDs.2

“People living with psoriatic arthritis may experience a variety of symptoms, making the condition particularly difficult to diagnose and treat,” said Angela Lukin, Regional President, Inflammation and Immunology, Pfizer. “We are proud that we are now able to offer XELJANZ as an option to adult patients living with active psoriatic arthritis in the European Union.”

Safety and efficacy of upadacitinib in patients with rheumatoid arthritis

A new randomised, double-blind, placebo-controlled phase 3 trial study published by Lancet.

Upadacitinib is a selective inhibitor of Janus kinase 1 and was efficacious in phase 2 studies in patients with moderate-to-severe rheumatoid arthritis

This study is a double-blind, placebo-controlled trial at 150 sites in 35 countries. We enrolled patients aged 18 years or older with active rheumatoid arthritis for 3 months or longer, who had received csDMARDs for at least 3 months with a stable dose for at least 4 weeks before study entry, and had an inadequate response to at least one of the following csDMARDs: methotrexate, sulfasalazine, or leflunomide
