A Study of ARRY-371797 in Patients With Active Ankylosing Spondylitis

October 13, 2020 updated by: Pfizer
This is a Phase 2 study, involving a 12-week treatment period, designed to evaluate the effectiveness of investigational study drug ARRY-371797 (versus placebo) in treating ankylosing spondylitis, and to further evaluate the drug's safety. Approximately 130 patients from the US, Canada, Poland and Hungary will be enrolled in this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Key Inclusion Criteria:

  • Diagnosis of ankylosing spondylitis according to the Modified New York Criteria (1984).
  • Inadequate response to at least 2 weeks of continuous treatment with NSAIDs, or unable to receive ≥ 2 full weeks of continuous treatment with NSAIDs because of intolerance.
  • If previously treated with a biological agent, patient must not have failed due to lack of efficacy, and must have completed an appropriate washout period prior to first dose of study drug.
  • Patients may continue on specified stable background therapies for ankylosing spondylitis (doses should be stable for at least 4 weeks prior to the first dose of study drug).
  • Additional criteria exist.

Key Exclusion Criteria:

  • Diagnosis of any other active or uncontrolled inflammatory or non-inflammatory articular disease that may interfere with disease activity assessments.
  • Previously treated with intravenous immunoglobulins within 6 months prior to first dose of study drug.
  • Patients requiring prohibited concomitant medications including moderate or strong CYP3A inhibitors, CYP3A inducers and Biologic Response Modifiers (BRMs) while on study.
  • Trauma or other major surgeries within 8 weeks prior to first dose of study drug.
  • Specific abnormal laboratory values or electrocardiogram abnormalities.
  • Known positive serology for human immunodeficiency virus (HIV), hepatitis C, and/or hepatitis B.
  • Additional criteria exist.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Assess the efficacy of the study drug (versus placebo) in terms of Assessments in Ankylosing Spondylitis 20% Working Group response criterion (ASAS 20).
Time Frame: 12 weeks
12 weeks
Characterize the safety profile of the study drug in terms of adverse events, clinical laboratory tests and electrocardiograms.
Time Frame: 12 weeks
12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Characterize the pharmacokinetics (PK) of the study drug and a metabolite in terms of plasma concentrations.
Time Frame: 12 weeks
12 weeks
Explore potential biomarkers for pharmacodynamics (PD).

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 16, 2008

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
September 29, 2009

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
