What researchers measure

Primary outcomes

  1. Change in mdsTBR (Most-diseased Segment TBR [Target-to-background Ratio]) of Index Vessel From Baseline to Week 12 in Participants With Baseline Elevated hsCRP (≥ 2 milligrams per liter [mg/L])

    hsCRP=high-sensitivity C-reactive protein.

    Time frame: Baseline up to Week 12

Secondary outcomes

  1. Change From Baseline in mdsTBR of Index Vessel at Week 12 in all Participants (hsCRP < 2 mg/L and ≥ 2mg/L)

    Time frame: Baseline and Week 12

  2. Change From Baseline in mdsTBR of Carotids at Week 12 in all Participants (hsCRP < 2 mg/L and ≥ 2 mg/L)

    Time frame: Baseline and Week 12

  3. Change From Baseline in mdsTBR of Carotids at Week 12 in Participants With Baseline Elevated hsCRP (≥ 2 mg/L)

    Time frame: Baseline and Week 12

  4. Change From Baseline in Active Segments TBR and the Whole Vessel TBR of the Index Vessel at Week 12 in all Participants (hsCRP < 2 mg/L and ≥ 2 mg/L)

    Time frame: Baseline and Week 12

  5. Change From Baseline in Active Segments TBR and the Whole Vessel TBR of the Index Vessel at Week 12 in Participants With Baseline Elevated hsCRP (≥ 2 mg/L)

    Time frame: Baseline and Week 12

  6. Number of Participants With Adverse Events (AEs) and Severity of AEs Determined According to the NCI CTCAE v5.0 Grading Scale

    NCI CTCAE v5.0 = National Cancer Institute's Common Terminology Criteria for Adverse Events, Version 5.0.

    Time frame: Up to approximately 22 weeks

  7. Plasma Concentration of Selnoflast at Specified Timepoints

    Time frame: Up to 12 weeks
