Strategic considerations

Polymyalgia rheumatica (PMR) is an inflammatory disease causing shoulder, hip, and neck pain and stiffness, in adults aged 50 years or older. This study evaluates how safe and effective ABBV-154 is in participants with glucocorticoid-dependent PMR. Adverse events and change in disease activity will be assessed.

ABBV-154 is an investigational drug being evaluated for the treatment of PMR. Participants will be randomized into 1 of 4 treatment groups or arms, each arm receiving a different treatment. There is a 1 in 4 chance that a participant will be assigned to placebo. Around 160 participants, of at least 50 years of age, with PMR will be enrolled in the study at approximately 95 sites worldwide.

The study is compromised of a 52 week double-blind, placebo-controlled period and a follow-up visit 70 days after the last dose of the study drug. All participants will receive a glucocorticoid taper along with the assigned dose of ABBV-154 or placebo, subcutaneously (SC) every other week (eow).

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Inclusion Criteria:

• Clinical diagnosis of Polymyalgia Rheumatica (PMR) and fulfillment of the 2012 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) provisional classification criteria for PMR.
• Must have had at least 2 episodes of unequivocal PMR flare.
• Must be on a stable dose of prednisone.
• Must be willing to follow the protocol-defined glucocorticoid tapering regimen.

Exclusion Criteria:

• Have been treated with a prior TNF antagonist.
• Current use of immunomodulators other than prednisone and hydroxychloroquine.

AbbVie is committed to responsible data sharing regarding the clinical trials we sponsor. This includes access to anonymized, individual and trial-level data (analysis data sets), as well as other information (e.g., protocols, analyses plans, clinical study reports), as long as the trials are not part of an ongoing or planned regulatory submission. This includes requests for clinical trial data for unlicensed products and indications.

Access to this clinical trial data can be requested by any qualified researchers who engage in rigorous independent scientific research, and will be provided following review and approval of a research proposal and statistical analysis plan and execution of a data sharing statement. Data requests can be submitted at any time after approval in the US and/or EU and a primary manuscript is accepted for publication.
