Tocilizumab Discontinuation After Attaining Remission in Patients with Rheumatoid Arthritis who were Treated with Tocilizumab Alone or in Combination with Methotrexate: Results from a Prospective Randomised Controlled Study (the second year of the SURPRISE study)

The second-year results from the SURPRISE study show that low disease activity (LDA) can be maintained after discontinuation of tocilizumab with continued methotrexate after remission is achieved. Discontinuation of biologic agents in patients who have achieved remission or low disease activity (LDA) is desirable from a risk–benefit point of view. Compared with TNF inhibitors, little is known regarding TCZ-free remission or LDA, but studies indicate that only a small proportion of patien...

Herpes Zoster and Tofacitinib Therapy in Patients with Rheumatoid Arthritis

Arthritis Rheumatol 2014;66:2675–84

Patients who were treated with tofacitinib in the RA clinical development programme were more likely to develop herpes zoster than were those who received placebo. Cases of herpes zoster reported by investigators in the Phase 2, Phase 3 and long-term extension studies of tofacitinib were evaluated. Herpes zoster was noted in 5% of tofacitinib-treated patients; only 7% of these cases were serious, no patients with herpes zoster died and only 10% permanently discontinued tofacitinib treatment. T...

This Phase II study assessed the safety and efficacy of olokizumab in Asian patients with moderate-to-severe rheumatoid arthritis, previously exposed to anti-TNF therapy. After 12 weeks of treatment, olokizumab was found to rapidly improve disease activity in patients who had previously failed anti-TNF therapy. There was also a significant decrease in ACR20 and ACR50 responder rates at week 12. The safety findings were consistent with the safety profile expected for this drug class. These findin...

Efficacy and safety of tofacitinib as monotherapy in Japanese patients with active rheumatoid arthritis: a 12-week, randomized, phase 2 study

Tanaka Y, Takeuchi T, Yamanaka H, Nakamura H, Toyoizumi S, Zwillich S.
Modern Rheumatology. 2015 Jul;25(4):514-21. doi: 10.3109/14397595.2014.995875.

The oral Janus kinase (JAK) inhibitor, Tofacitinib, preferentially inhibits signalling by heterodimeric receptors associated with JAK3 and/or JAK1, blocking signalling for several cytokines. The purpose of this study was to evaluate the efficacy of tofacitinib monotherapy versus placebo in Japanese patients with inadequate response to disease-modifying anti-rheumatic drugs (DMARDs). Data on response rates – ACR20/50/70, DAS28-4(ESR), and HAQ-DI – laboratory parameters and adverse eve...

Efficacy and Safety of Tofacitinib as Monotherapy in Japanese Patients With Active Rheumatoid Arthritis: A 12-Week, Randomized, Phase 2 Study

Mod Rheumatol. 2014 Dec 11:1–25. [Epub ahead of print]

In Japan, the biologic DMARDs infliximab, etanercept, adalimumab, golimumab and certolizumab pegol, as well as tocilizumab and abatacept are approved for use in patients with active RA and an inadequate response to existing therapies. However, not all patients respond to these therapies adequately, creating an unmet need for therapeutic options with alternative mechanisms of action. The oral JAK inhibitor tofacitinib has demonstrated efficacy as monotherapy or in combination with DMARDs for th...

Herpes Zoster and Tofacitinib Therapy in Patients with Rheumatoid Arthritis

Winthrop KL, Yamanaka H, Valdez H, et al.
Arthritis Rheumatol. 2014 Jun 18. [Epub ahead of print]

It is well established that patients with RA are at an increased risk of herpes zoster (HZ). What is less well known is whether some of the newer therapies available for treatment of RA increase this risk. Tofacitinib has been reported to be associated with an increased risk of HZ and this study quantifies that risk and reviews potential factors that represent an increased risk. Using data from the tofacitinib RA development programme; phase 2, 3, and long-term extension clinical trials, over 20...
