Results from Upadacitinib Phase 3 SELECT-MONOTHERAPY Study Published in The Lancet

Press release   •   May 28, 2019 08:00 BST

      • SELECT-MONOTHERAPY evaluates the safety and efficacy of upadacitinib monotherapy in adult patients with moderately to severely active rheumatoid arthritis and inadequate response to a stable dose of methotrexate1
      • Upadacitinib (15 mg and 30 mg), once daily, achieved both primary endpoints with significantly higher rates of ACR20 response and low disease activity (defined as DAS28[CRP]≤3.2) at week 14 versus continued treatment with methotrexate1
      • Patients receiving either dose of upadacitinib monotherapy also achieved significantly higher rates of clinical remission (defined as DAS28[CRP]<2.6) at week 14 than those continuing methotrexate 1
      • The safety profile of upadacitinib was consistent with previously reported Phase 3 studies1

      Maidenhead, 28 May, 2019 — AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced the publication of positive results from the pivotal Phase 3 SELECT-MONOTHERAPY clinical trial in The Lancet. The study, in 648 patients evaluates upadacitinib as a monotherapy treatment versus continuing methotrexate in patients with moderately to severely active rheumatoid arthritisand an inadequate response to methotrexate.1 After 14 weeks of treatment, both once-daily doses of upadacitinib (15 mg n=217 and 30 mg n=215) met the study's primary endpoints with significantly higher rates of ACR20** and low disease activity (LDA)*** versus continuing stable methotrexate therapy (n=216).1 Both doses also achieved all key secondary endpoints, including the proportion of patients achieving remission**** and improvements in physical function (defined as change in HAQ-DI from baseline).1 Upadacitinib, an oral investigational JAK1-selective inhibitor is not approved by regulatory authorities and its safety and efficacy have not been established.

      "These results show that upadacitinib as a monotherapy can provide clinically meaningful responses, including low disease activity, remission and significant improvements in physical function,” said Josef S. Smolen, M.D., Department of Medicine, Division of Rheumatology, Medical University of Vienna, Austria, and first author on the publication. "Data from this study support the potential for upadacitinib as an important treatment option for patients with rheumatoid arthritis."

      Rheumatoid arthritis, which affects an estimated 400,000 people in the UK, is a chronic and debilitating disease. 2 Methotrexate is commonly used as a first-line therapy in rheumatoid arthritis, but many patients do not respond to or cannot tolerate methotrexate, which puts them at risk for disease progression.3-5 After inadequate response to methotrexate alone, methotrexate is commonly used as a background therapy with biologic DMARDs to optimise their efficacy.4,6

      “We are encouraged by the positive results published in The Lancet," said Alice Butler, UK Medical Director, AbbVie. "Data from this study, the third of six in the SELECT clinical trial programme evaluating the potential for upadacitinib in rheumatoid arthritis, helps to deepen our understanding of JAK1-selective inhibition and the potential for monotherapy in this complex disease”

      Results showed that after 14 weeks, 68 percent and 71 percent of patients who switched to upadacitinib monotherapy 15 mg and 30 mg at baseline, respectively, achieved ACR20 versus 41 percent of patients who continued to receive methotrexate therapy (p≤0.0001 for both doses). 1 Low disease activity***was achieved by 45 percent of patients receiving upadacitinib 15 mg and 53 percent receiving upadacitinib 30 mg versus 19 percent receiving methotrexate (p<0.0001 for both doses) at week 14.1

      The study also showed a significantly higher proportion of upadacitinib patients in both dose groups achieved clinical remission****, ACR50 and ACR70 at week 14 compared to patients continuing on methotrexate. 1 28 and 41 percent of upadacitinib-treated patients in the 15 mg and 30 mg groups, respectively, achieved clinical remission**** compared to 8 percent of those who continued methotrexate (p≤0.0001 for both doses).1 ACR50 and ACR70 were achieved by 42 and 23 percent, 52 and 33 percent for patients in the 15 mg and 30 mg upadacitinib groups, respectively, versus 15 and 3 percent of patients continuing on methotrexate.1

      *All week 14 endpoints shown in the table achieved p-values of <0.001 versus methotrexate for both doses. Not all key secondary endpoints shown. Methotrexate patients shown are patients who continued on their baseline methotrexate dose in a blinded manner.

      **ACR20/50/70 is defined as American College of Rheumatology 20 percent/50 percent/70 percent improvements in both tender and swollen joint counts, plus 3 of the following: patient assessments of pain, global disease activity and physical function, physician global assessment of disease activity and acute phase reactant.

      *** LDA was defined by a clinical response Disease Activity Score with 28 joint counts (C-reactive protein) (DAS28 [CRP]) less than or equal to 3.2.

      **** Clinical remission was based on DAS28 (CRP) less than 2.6.

      In the study, the safety profile of upadacitinib was consistent with previously reported Phase 3 SELECT clinical trials. 1,7-11 Serious adverse events occurred in 5 percent/3 percent of patients in the 15 mg/30 mg upadacitinib groups, respectively, compared to 3 percent in the methotrexate group.1 Three major adverse cardiovascular events (MACE) occurred in patients with known cardiovascular (CV) risk factors (one in the 15 mg group and two in the 30 mg group).1 One MACE in the 15 mg arm was a fatal hemorrhagic stroke due to a ruptured aneurysm.1 No other deaths were reported.1 There was one adjudicated pulmonary embolism (PE) reported in the 15 mg group in a patient with multiple known risk factors.1 Three malignancies were reported in the study, one in the methotrexate group and two in the 15 mg group.1 One patient in the upadacitinib 15 mg group and one in the methotrexate group experienced a serious infection.1 Herpes zoster was reported by one (1 percent) patient in the methotrexate group, three (1 percent) in the 15 mg group, and six (3 percent) in the 30 mg group.1

      About SELECT-MONOTHERAPY1

      SELECT-MONOTHERAPY is a Phase 3, multicentered, randomised, double-blind, double-dummy study designed to evaluate the safety and efficacy of upadacitinib monotherapy in adult patients with moderately to severely active rheumatoid arthritis and an inadequate response to a stable dose of methotrexate. Patients were randomised to switch from methotrexate to upadacitinib monotherapy (15 mg (n=217) or 30 mg (n=215)) once-daily or continue on their prior stable dose of methotrexate (n=216) in a blinded manner.

      The two independent primary endpoints comparing upadacitinib 15 mg and 30 mg with continued methotrexate included the percentage of subjects achieving an ACR20 response and low disease activity (LDA)*** after 14 weeks of treatment. Key secondary endpoints included the proportion of patients achieving ACR50, ACR70 and clinical remission**** at week 14. The trial is ongoing and the second phase is a blinded long-term extension period, of up to five years, to evaluate the long-term safety, tolerability, and efficacy of the two once-daily doses (15 mg and 30 mg) of upadacitinib monotherapy in patients who have completed the first phase. More information on this trial can be found at www.clinicaltrials.gov (NCT02706951).

      About the SELECT Study Programme1,7-11

      The robust SELECT Phase 3 rheumatoid arthritis programme evaluates more than 4,900 patients with moderately to severely active rheumatoid arthritis in six studies.
