Patients given tofacitinib (TOF) who achieved Routine Assessment of Patient Index Data 3 (RAPID3) remission or low disease activity (LDA) at 6 months, had improved long-term outcomes at 2 years, compared to patients with moderate or high disease activity (MDA/HDA) at 6 months.RAPID3¹ is a patient-reported evaluation of disease activity, based on pooled PROs; patient global assessment, patient assessment of arthritic pain and HAQ-DI scores. Previous studies with tocilizumab have suggested that RA...

This post hoc analysis of 2 randomised controlled trials (RCTs) AMBITION and ADACTA found that tocilizumab monotherapy results in substantial and clinically meaningful improvements in patient-reported outcomes (PROs) over 24 weeks.PROs assessed included patient global assessment (PtGA), pain, HAQ-DI, Functional Assessment of Chronic Illness Therapy (FACIT-F) and Short-Form-36 (SF-36) physical component summary (PCS) and mental component summary (MCS) and eight domain scores.Tocilizumab (TCZ) mon...

Evidence is presented that treatment with sarilumab improves patient-reported outcomes (PROs). These improvements complement the clinical efficacy previously reported for sarilumab.Data were analysed from the 52-week Phase 3 MOBILITY randomised controlled trial in adult patients with active RA and previous inadequate response to MTX. Patients received subcutaneous placebo or sarilumab 150 mg or 200 mg every 2 weeks in combination with MTX, for 52 weeks.PROs assessed were: Patient Global Assessme...

This real-life study confirms findings from the tocilizumab (TCZ) clinical development program that IL-6 inhibition with TCZ may be associated with increased risk of lower intestinal perforation (LIP). Data were analysed from the RABBIT register of patients. The primary outcome was the incidence of LIPs in patients exposed to TCZ, csDMARDs, TNFis, abatacept, or rituximab. Thirty-seven LIPs were observed in 53,972 patient years. The proportion of patients who developed a LIP was higher in patient...

Extended-release once-daily formulation of tofacitinib: evaluation of pharmacokinetics compared with immediate-release tofacitinib and impact of food

J Clin Pharmacol. 2016 Mar 11. doi: 10.1002/jcph.734. [Epub ahead of print]

Lamba et al.

PK profile of TOF is rapid absorption and elimination with time to max concentration 0.5-1 hour and terminal half-life at 3 hours. It is currently approved for immediate release (IR) 5 mg BID, 10 mg total; however, decreasing the dosage to QD dosing may help increase compliance. This study performed in 24 healthy males compared the PK of XR and IR TOF under both single and multiple dose conditions and evaluated the effect of a high-fat meal on the PK of XR TOF. There were no clinically important...

Cost-effectiveness of Tofacitinib in the Treatment of Moderate to Severe Rheumatoid Arthritis in South Korea

This study evaluated the cost-effectiveness of introducing tofacitinib, an oral Janus kinase inhibitor, to the treatment of Korean patients with RA and an inadequate response to conventional DMARDs. The model showed that the inclusion of tofacitinib as a treatment strategy for moderate to severe RA is cost-effective; this conclusion was considered robust based on multiple sensitivity analyses.First-line tofacitinib used before the standard of care (base-case analysis) increased both treatment c...

Changes in serum creatinine in patients with active rheumatoid arthritis treated with tofacitinib: results from clinical trials

et al.

Despite preclinical and healthy volunteer studies of tofacitinib showing no evidence of nephrotoxicity, increases in mean serum creatinine levels have been observed in patients treated with the drug during the RA clinical development programme. This report explores the clinical significance of this change.

Serum creatinine values and renal adverse event data were pooled from patients who received =1 dose of tofacitinib either with background DMARDs or as monotherapy in five Phase 3 studie...

PI3K-δ and PI3K-γ inhibition by IPI-145 abrogates immune responses and suppresses activity in autoimmune and inflammatory disease models

Phosphoinositide-3 kinases (PI3K) are cell signalling proteins that act as a central node for relaying signals from cell surface receptors and downstream mediators. Specifically they phosphorylate phosphatidylinositol to phosphatidylinositol-3,4,5-trisphosphate (PIP3). This acts a docking site for signalling proteins, leading to the activation of downstream effectors such as BTK. Therefore, inhibition of the PI3K-d and PI3K-? isoforms (PI3K-a and PI3K-ß demonstrated embryonic lethality in murine...

Open-label tofacitinib and double-blind atorvastatin in rheumatoid arthritis patients: a randomised study

This randomised, placebo-controlled, multicentre phase 2 study evaluated the efficacy and safety of atorvastatin versus placebo in modifying lipids in 111 patients with active rheumatoid arthritis (RA) receiving tofacitinib. All patients took tofacitinib 10 mg twice daily for 12 weeks, and after the first 6 weeks patients were randomised 1:1 to receive either atorvastatin 10 mg once daily (n=50) or matched placebo (n=48) in a double-blind phase for a further 6 weeks. Tofacitinib-induced elevatio...
