Wollenhaupt J, Lee EB, Curtis JR, Silverfield J, Terry K, Soma K, Mojcik C, DeMasi R, Strengholt S, Kwok K, Lazariciu I, Wang L, Cohen S.
Arthritis Res Ther. 2019 Apr 5;21(1):89.

TOF 5 mg and 10mg BID demonstrated a consistent safety profile and sustained efficacy for up to 9.5 years in this open-label LTE ORAL Sequel study. TOF 5 mg and 10 mg BID demonstrated consistent safety (as monotherapy and combination therapy) and efficacy within this open-label LTE study of RA patients. As RA requires long-term treatment, it’s important to assess the long-term efficacy and safety of RA therapies to understand the potential lifelong impact on patient health and quality of ...

Evaluation of the Short-, Mid-, and Long-term Effects of Tofacitinib on Lymphocytes in Patients with Rheumatoid Arthritis

van Vollenhoven R, Lee EB, Strengholt S, Mojcik C, Valdez H, Krishnaswami S, Biswas P, Lazariciu I, Hazra A, Clark JD, Hodge J, Wang L, Choy E.
Arthritis Rheumatol 2018 DOI: 10. 1002/art.40780

Tofacitinib (TOF) treatment is associated with short-term transient increases in absolute lymphocyte counts (ALC), followed by a gradual decline to reach steady state by ~48 months. Changes in both ALC and lymphocyte subset counts (LSC) were reversible upon TOF discontinuation. Low ALC but not LSC were associated with an increased risk of serious infective episodes (SIEs) and herpes zoster (HZ). This data supported the treatment recommendations on ALC counts for starting and continuing therapy w...

Tofacitinib in Rheumatoid Arthritis: Lack of Early Change in Disease Activity Predicts a Low Probability of Achieving Low Disease Activity at Month 6

Van Vollenhoven RF, Lee EB, Fallon L, Zwillich SH, Wilkinson B, Chapman D, Demasi R, Keystone E.
Arthritis Care Res (Hoboken) 2019 Jan;71(1):71-79. DOI: 10.1002/acr.23585

This post-hoc analysis of two, Phase 3 studies, ORAL Start and ORAL Standard shows that early treatment response can predict long-term disease activity outcomes. EULAR recommendations suggest that treat-to-target strategies require regular target assessments with treatment approaches changed if targets are not reached at 6 months. To optimize this strategy, therapy outcomes should be known, and the relationship between short and long-term outcomes defined. The current analysis focused on the d...

Evaluation of Disease Activity in Patients with Rheumatoid Arthritis Treated with Tofacitinib by RAPID3: Post Hoc Analyses from Two Phase 3 Trials

Strand V, Lee EB, Yazici Y, Dikranian A, Wilkinson B, Takiya L, Zang C, Bananis E, Bergman MJ.
Clin Rheumatol 2018 Aug; 37(8):2043–53

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 ...

Analysis of Non-melanoma Skin Cancer across the Tofacitinib Rheumatoid Arthritis Clinical Programme

Curtis JR, Lee EB, Martin G, Mariette X, Terry TT, Chen Y, Geier J, Andrews J, Kaur M, Fan H, Nduaka CI.
Clin Exp Rheumatol 2017;35:614–22

Because non-melanoma skin cancer (NMSC) is one of the most common malignancies associated with RA immunomodulatory therapies, this analysis looked to determine the rate of NMSC incidence per 100 patient-years in patients with RA receiving TOF in the clinical trial programme. The Phase 1, 2, and 3 IRs (combined) for both TOF 5- and 10 mg were low and comparable to those of adalimumab, MTX and placebo, IRs remained stable over time. TOF doses used in the 2 Phase 1; 8 Phase 2; and 6 Phase 3 studi...

Long-term safety of tofacitinib for the treatment of rheumatoid arthritis up to 8.5 years: integrated analysis of data from the global clinical trials

Cohen BS, Tanaka Y, Mariette X, Curtis JR, Lee EB, Nash P, Winthrop KL, Charles-Shoeman C, Thirunavukkarasu K, DeMasi R, Geier J, Kwok K, Wang L, Riese R, Wollenhaupt J.
Ann Rheum Dis 2017;76:1253-1262. DOI 10.1136/annrheumdis-2016-210457

This analysis of exposure to tofacitinib, an oral JAKi for the treatment of RA, for up to 8.5 years allowed estimation of safety events with improved precision versus previous tofacitinib reports. Adverse events were generally stable over time; no new safety signals were observed compared with previous tofacitinib reports. Data were collated into an integrated safety summary of tofacitinib in adult patients with active RA, and included data spanning the tofacitinib clinical programme: from 2 P...

Tofacitinib, an oral Janus kinase inhibitor: analysis of malignancies across the rheumatoid arthritis clinical development programme

Curtis JR, Lee EB, Kaplan IV, Kwok K, Geier J, Benda B, Soma K, Wang L, Riese R.
Ann Rheum Dis. 2015 Apr 22. pii: annrheumdis-2014-205847. doi: 10.1136/annrheumdis-2014-205847. [Epub ahead of print]

The developments of certain malignancies associated with chronic inflammatory diseases such as RA is known to occur to a greater extent than that of the general population. It is also know that certain RA treatments can affect malignancy rates. As such, newer immunomodulatory agents, such as the JAK inhibitor tofacitinib, are closely monitored for safety events of special interest, including malignancies. This paper analyses pooled malignancy data from the tofacitinib RA clinical development...

The effect of tofacitinib on pneumococcal and influenza vaccine responses in rheumatoid arthritis

Winthrop KL, Silverfield J, Racewicz A, Neal J, Lee EB, Hrycaj P, Gomez-Reino J, Soma K, Mebus C, Wilkinson B, Hodge J, Fan H, Wang T, Bingham CO 3rd.
Ann Rheum Dis. 2015 Mar 20. pii: annrheumdis-2014-207191. doi: 10.1136/annrheumdis-2014-207191. [Epub ahead of print]

The increased risk of serious infection among RA patients means vaccinations against pneumococcus and influenza are recommended in this group of patients. Studies evaluating immune response to these vaccines in conjunction with DMARD therapy can provide clinicians with important information relating to things such as timing of vaccination. This study aimed to assess the effect of tofacitinib on vaccine responses to PPSV-23 and the trivalent seasonal influenza vaccine in those whom tofacitinib...

Tofacitinib Versus Methotrexate In Rheumatoid Arthritis

Lee EB, Fleischmann R, Hall S, et al.
N Engl J Med. 2014;370(25):2377–2386.

ORAL Start is the latest trial to be reported in the tofacitinib clinical development programme. It compares the use of tofacitinib monotherapy to MTX monotherapy, in RA patients who have had either no or a sub-therapeutic dose of MTX in the past. Nine hundred and fifty eight patients received either tofacitinib (5 mg or 10 mg) twice daily, or methotrexate at a dose that was incrementally increased to 20 mg per week over 8 weeks. The co primary efficacy endpoints were ACR 70 response, and mean c...

Safety and Efficacy of Tofacitinib, an Oral Janus Kinse Inhibitor, for the Treatment of Rheumatoid Arthritis, in Open-Label Longterm Extension Studies

Wollenhaupt J, SIlverfield J, Lee Eb et al.
J Rheumatol 2014;41;837-852

This study pooled data from two LTE studies involving patients who had previously participated in qualifying phase I, II and III studies. Data up to 60 months was included for safety aspects and efficacy data up to 48 months. However data for 10 mg BID and tofacitinib monotherapy was limited after 24 and 36 months respectively. Over the two studies, 4102 patients were treated for a total of 5963 patient years. Herpes zoster, both serious and non-serious, had a higher incidence rate in tofacitini...
