Concerns surrounding increased rates of PE and cardiovascular associated deaths has led to black box warnings when prescribing JAK inhibitors. As such, ongoing investigations regarding cardiovascular and VTE event risks in JAK inhibitor therapies, both clinical and real-world, are vital. Mease and colleagues consider data from clinical tofacitinib development programmes, and the ongoing real-data study A3921133. Conclusions from data analysis state that those with pre-existing cardiovascular and...

This 3-year, open-label, LTE study follows PsA patients previously treated in pivotal studies OPAL Broaden and OPAL Beyond. It demonstrates maintained safety and efficacy of tofacitinib up to 36 and 30 months, respectively. No new safety concerns are highlighted. Previous P3 studies, OPAL Broaden and OPAL Beyond, demonstrated safety and efficacy of 5mg and 10mg tofacitinib BID in PsA. These patients rolled over to OPAL Balance for a period of 36 months. 686 participants were used in this inter...

Patients with psoriatic arthritis (PsA) had similar safety profile with TOF to that of other systemic therapies in real-world settings, except for the known risk of HZ. Treatment recommendations from EULAR and GRAPPA for patients with PsA vary according to adverse prognostic risk factors, disease manifestations and responsiveness to prior treatment. Safety concerns for most PsA therapies include gastrointestinal AEs, hepatotoxicity, opportunistic infections (OIs) including TB, and SIEs. This s...

Tofacitinib for Psoriatic Arthritis in Patients with an Inadequate Response to TNF Inhibitors

Gladman D, Rigby W, Azevedo VF, Behrens F, Blanco R, Kaszuba A, Kudlacz E, Wang C, Menon S, Hendrikx T, Kanik KS.
N Engl J Med 2017;377:1525–36.

The study data presented that tofacitinib (TOF) improves efficacy response rates in patients with severe psoriatic arthritis (PsA) who have an inadequate response to TNF inhibitors. The Phase 3 Oral Psoriatic Arthritis Trial (OPAL) Beyond study evaluated patients with active PsA who had inadequate responses to more than one TNFi. Patients were randomised 2:2:1:1 to 5 mg TOF BID or 10 mg TOF BID for 6 months; or PBO, with a switch to 5 mg TOF BID or to 10 mg BID at 3 months. Primary endpoints w...

Effects of tofacitinib monotherapy on patient-reported outcomes in a randomized phase 3 study of patients with active rheumatoid arthritis and inadequate responses to DMARDs

RA presents a significant health and socioeconomic burden particularly in physical functioning, fatigue, and emotional roles. A phase III 6-month study of tofacitinib in patients with active RA, who had prior inadequate responses to cDMARDs or bDMARDs, uses patient-reported outcomes (PROs) to assess the impact on quality of life. Patients were randomized 4:4:1:1 to receive tofacitinib 5 or 10 mg BID, or placebo for 3 months followed by tofacitinib 5 or 10 mg BID. At month 3, tofacitinib 5 and ...
