Background: Many patients with rheumatoid arthritis (RA) do not achieve adequate and safe responses with disease-modifying antirheumatic drugs (DMARDs). Tofacitinib is a novel, oral, Janus kinase inhibitor that treats RA. Objective: To evaluate the efficacy and safety of tofacitinib in combination with nonbiologic DMARDs. Design: 1-year, double-blind, randomized trial (ClinicalTrials.gov: NCT00856544). Setting: 114 centers in 19 countries. Patients: 792 patients with active RA despite nonbiologic DMARD therapy. Intervention: Patients were randomly assigned 4:4:1:1 to oral tofacitinib, 5 mg or 10 mg twice daily, or placebo advanced to tofacitinib, 5 mg or 10 mg twice daily. Measurements: Primary end points were 20% improvement in American College of Rheumatology (ACR20) criteria; Disease Activity Score for 28-joint counts based on the erythrocyte sedimentation rate (DAS28-4[ESR]) of less than 2.6; DAS28-4(ESR)defined remission, change in Health Assessment Questionnaire Disability Index (HAQ-DI) score, and safety assessments. Results: Mean treatment differences for ACR20 response rates (month 6) for the 5-mg and 10-mg tofacitinib groups compared with the combined placebo groups were 21.2% (95% CI, 12.2% to 30.3%; P Ͻ 0.001) and 25.8% (CI, 16.8% to 34.8%; P Ͻ 0.001), respectively. The HAQ-DI scores (month 3) and DAS28-4(ESR) less than 2.6 response rates (month 6) were also superior in the tofacitinib groups versus placebo. The incidence rates of serious adverse events for patients receiving 5-mg tofacitinib, 10-mg tofacitinib, or placebo were 6.9, 7.3, or 10.9 events per 100 patientyears of exposure, respectively. In the tofacitinib groups, 2 cases of tuberculosis, 2 cases of other opportunistic infections, 3 cardiovascular events, and 4 deaths occurred. Neutrophil counts decreased, hemoglobin and low-and high-density lipoprotein cholesterol levels increased, and serum creatinine levels had small increases in the tofacitinib groups. Limitations: Placebo groups were smaller and of shorter duration. Patients received primarily methotrexate. The ability to assess drug combinations other than tofacitinib plus methotrexate was limited. Conclusion: Tofacitinib improved disease control in patients with active RA despite treatment with nonbiologic DMARDs, primarily methotrexate.

Objective. Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We compared patient-reported outcomes (PROs) in patients with RA treated with tofacitinib or placebo in combination with conventional disease-modifying antirheumatic drugs (DMARDs). Methods. In a 12-month, phase III randomized controlled trial (ORAL Sync), patients (n 5 795) with active RA and previous inadequate response to therapy with ‡1 conventional or biologic DMARD were randomized 4:4:1:1 to tofacitinib 5 mg twice daily (BID), tofacitinib 10 mg BID, placebo advanced to 5 mg BID, or placebo to 10 mg BID, in combination with stable background DMARD therapy. PROs included patient global assessment of arthritis (PtGA), patient assessment of arthritis pain (Pain), physical function (Health Assessment Questionnaire disability index [HAQ DI]), health-related quality of life (Short Form 36 health survey [SF-36]), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-F]), and sleep (Medical Outcomes Study Sleep [MOS Sleep]). Results. At month 3, statistically significant improvements from baseline versus placebo were reported in PtGA, Pain, HAQ DI, all 8 SF-36 domains, FACIT-F, and MOS Sleep with tofacitinib 10 mg BID, and in PtGA, Pain, HAQ DI, 7 SF-36 domains, FACIT-F, and MOS Sleep with tofacitinib 5 mg BID. Improvements were sustained to month 12. Significantly more tofacitinib-treated patients reported improvements of greater than or equal to the minimum clinically important differences at month 3 versus placebo in all PROs, except the SF-36 role-emotional domain (significant for tofacitinib 10 mg BID). Conclusion. Patients with active RA treated with tofacitinib combined with background conventional DMARD therapy reported sustained, significant, and clinically meaningful improvements in PROs versus placebo.

Placebo-Controlled Trial of Tofacitinib Monotherapy in Rheumatoid Arthritis
New England Journal of Medicine, 2012
Background Tofacitinib (CP-690,550) is a novel oral Janus kinase inhibitor that is being investigated as a targeted immunomodulator and disease-modifying therapy for rheumatoid arthritis. Methods In this phase 3, double-blind, placebo-controlled, parallel-group, 6-month study, 611 patients were randomly assigned, in a 4:4:1:1 ratio, to 5 mg of tofacitinib twice daily, 10 mg of tofacitinib twice daily, placebo for 3 months followed by 5 mg of tofacitinib twice daily, or placebo for 3 months followed by 10 mg of tofacitinib twice daily. The primary end points, assessed at month 3, were the percentage of patients with at least a 20% improvement in the American College of Rheumatology scale (ACR 20), the change from baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) scores (which range from 0 to 3, with higher scores indicating greater disability), and the percentage of patients with a Disease Activity Score for 28-joint counts based on the erythrocyte sedimentation rate (DAS28-4[ESR]) of less than 2.6 (with scores ranging from 0 to 9.4 and higher scores indicating more disease activity). Results At month 3, a higher percentage of patients in the tofacitinib groups than in the placebo groups met the criteria for an ACR 20 response (59.8% in the 5-mg tofacitinib group and 65.7% in the 10-mg tofacitinib group vs. 26.7% in the combined placebo groups, P<0.001 for both comparisons). The reductions from baseline in HAQ-DI scores were greater in the 5-mg and 10-mg tofacitinib groups than in the placebo groups (−0.50 and −0.57 points, respectively, vs. −0.19 points; P<0.001). The percentage of patients with a DAS28-4(ESR) of less than 2.6 was not significantly higher with tofacitinib than with placebo (5.6% and 8.7% in the 5-mg and 10-mg tofacitinib groups, respectively, and 4.4% with placebo; P = 0.62 and P = 0.10 for the two comparisons). Serious infections developed in six patients who were receiving tofacitinib. Common adverse events were headache and upper respiratory tract infection. Tofacitinib treatment was associated with elevations in low-density lipoprotein cholesterol levels and reductions in neutrophil counts. Conclusions In patients with active rheumatoid arthritis, tofacitinib monotherapy was associated with reductions in signs and symptoms of rheumatoid arthritis and improvement in physical function.

Effectiveness and safety of tofacitinib in rheumatoid arthritis: a cohort study
Arthritis research & therapy, 2018
Tofacitinib is the first oral Janus kinase inhibitor approved for the treatment of rheumatoid arthritis (RA). We compared the effectiveness and safety of tofacitinib, disease-modifying antirheumatic drugs (DMARDs), tumor necrosis factor inhibitors (TNFi), and non-TNF biologics in patients with RA previously treated with methotrexate. We used MarketScan® databases (2011-2014) to study methotrexate-exposed patients with RA who were newly prescribed tofacitinib, DMARDs other than methotrexate, and biologics. The date of first prescription was defined as the cohort entry. The therapy was considered effective if all of the following criteria from a claims-based algorithm were achieved at the first year of follow-up: high adherence, no biologic or tofacitinib switch or addition, no DMARD switch or addition, no increase in dose or frequency of index drug, no more than one glucocorticoid joint injection, and no new/increased oral glucocorticoid dose. The safety outcome was serious infection...

Objective. Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This post hoc analysis evaluated tofacitinib persistence in patients with RA in long-term extension (LTE) studies up to 9.5 years. Methods. Data were pooled from two LTE studies: ORAL Sequel (NCT00413699) and Study A3921041 (NCT00661661). Patients received tofacitinib 5 or 10 mg twice daily (BID), as monotherapy or with background conventional synthetic disease-modifying antirheumatic drugs. Kaplan-Meier estimates for tofacitinib drug survival and reasons for discontinuation were evaluated. Baseline factors were analyzed as predictors of persistence. Results. In 4967 tofacitinib-treated patients entering LTE studies, mean (maximum) treatment duration was 3.5 (9.4) years. Median drug survival (95% confidence interval) was 4.9 (4.7, 5.1) years. Estimated 2-and 5-year drug survival rates were 75.5% and 49.4%, respectively. Median drug survival was similar between the tofacitinib 5 and 10 mg BID groups, and slightly higher for patients receiving tofacitinib monotherapy versus combination therapy. Overall, 50.7% of patients discontinued tofacitinib; of these, 47.2% were due to adverse events and 7.1% for lack/ loss of efficacy. An increased risk of discontinuation was associated with baseline diabetes, hypertension, negative anticyclic citrullinated peptide (anti-CCP), negative rheumatoid factor (RF), and inadequate response to tumor necrosis factor inhibitors (TNFi-IR). Conclusion. Median drug survival of tofacitinib-treated patients participating in LTE studies was approximately 5 years and was similar for tofacitinib dosed at 5 and 10 mg BID. Reduced drug survival was associated with negative anti-CCP/RF status, TNFi-IR, and certain comorbidities. These data support tofacitinib use for long-term management of RA.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). Here, the safety and efficacy data from five Phase 2 studies of tofacitinib in patients with RA are summarized. Tofacitinib 1-30 mg twice daily was investigated, as monotherapy and in combination with methotrexate, in patients with RA. Tofacitinib 20 mg once daily was investigated in one study. Tofacitinib 5 and 10 mg twice daily were selected for investigation in Phase 3 studies; therefore, the efficacy and safety of tofacitinib 5 and 10 mg twice daily in Phase 2 studies are the focus of this review. Tofacitinib ≥ 5 mg twice daily was efficacious in a dose-dependent manner, with statistically significant and clinically meaningful reductions in the signs and symptoms of RA and patient-reported outcomes. The safety profile was consistent across studies. The efficacy and safety profile of tofacitinib in Phase 2 studies supported its further investigation and the selection of tofacitinib 5 mg twice daily and tofacitinib 10 mg twice daily for evaluation in Phase 3 studies.
The 6-month drug survival rate in patients with rheumatoid arthritis treated with tofacitinib
Annals of Medical Research, 2021
Aim: Rheumatoid arthritis (RA) is a progressive, inflammatory, autoimmune disease that particularly affects the joints. Tofacitinib is the first oral Janus kinase inhibitor approved for RA treatment. We aimed to analyze the 6-month drug survival rate and factors affecting the discontinuation of tofacitinib in RA patients. Materials and Methods: Age, gender, rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) levels, whether to continue treatment tofacitinib, if treatment is not continued what treatment is applied, use of biological agent before tofacitinib treatment were retrospectively recorded from the patient data. Results: 30 RA patients included in the study (29 female, 1 male) with a mean age of 50.5 ± 11.3 years. At the 6th month of treatment of tofacitinib, the drug survival rates were 50%. There was no significant difference between CCP positive and negative patients as well as between RF positive and negative patients in terms of drug survival rates (p = 0.92 and p = 0.90, respectively). The drug survival rates were alike in tofacitinib monotherapy and combined therapy of tofacitinib with any conventional DMARD (p = 0.36). The tofacitinib survival rates were similar in biologically naïve patients and in patients who had received at least one previous biological DMARD (p = 0.70). Conclusion: Half of the RA patients receiving tofacitinib treatment continue their treatment at the 6th month. The drug survival rate was not associated with co-treatment with conventional DMARD, auto-antibody positivities, and previously used biological DMARD therapy. These findings support that tofacitinib shows similar efficacy when used as combined or monotherapy, in seronegative or seropositive patients, and in biologic resistant or naive patients.

Objective. Tofacitinib is an oral JAK inhibitor for the treatment of rheumatoid arthritis (RA). The phase III, 24-month, placebo-controlled Oral Rheumatoid Arthritis (ORAL) Scan trial was undertaken to evaluate the efficacy, including inhibition of structural progression, and safety of tofacitinib in patients with active RA and an inadequate response to methotrexate (MTX). Month 24 data from the completed study are reported here. Methods. Patients were randomized 4:4:1:1 to receive tofacitinib 5 mg or 10 mg twice daily, or placebo, switched to tofacitinib 5 mg or 10 mg twice daily, with stable background MTX. Patients receiving placebo switched to tofacitinib at month 3 (nonresponders) or month 6 (remaining patients). Clinical efficacy, structural progression, and treatment-emergent adverse events were evaluated. Analyses were performed on the full analysis set with observed data or nonresponder imputation with no advancement penalty for clinical efficacy, and imputation by linear extrapolation for structural progression. Results. Overall, 797 patients were treated; 539 (67.6%) completed 24 months of treatment. Responses according to the American College of Rheumatology criteria for 20% improvement (ACR20), ACR50, and ACR70; the proportion of patients in whom remission or low disease activity was achieved according to the 4-variable Disease Activity Score in 28 joints using the erythrocyte sedimentation rate, Clinical Disease Activity Index, or Simplified Disease Activity Index; Boolean remission; and Health Assessment Questionnaire disability index scores were maintained from month 12 to 24 and were similar between tofacitinib dosages. Limited structural damage was observed at months 12 and 24. Safety events were similar in type and frequency for both tofacitinib dosages, and were consistent with those previously reported. Conclusion. Our findings indicate that clinical and radiographic treatment effects are sustained in months 12-24 in patients with RA receiving tofacitinib 5 mg or 10 mg twice daily plus MTX. The safety profile is consistent with that of other tofacitinib studies. ClinicalTrials.gov identifier: NCT00847613.
