Olumiant® (baricitinib) Prescribing Information Related to Adverse Events

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not predict the rates observed in a broader patient population in clinical practice.1

Please see US prescribing information for adverse reactions that occurred in ≥1% during the 36-week placebo-controlled period of the baricitinib alopecia areata trials.

Common Treatment-Emergent Adverse Events in the Alopecia Areata Clinical Trials

The baricitinib alopecia areata (AA) clinical trial program includes

  • BRAVE-AA1, an adaptive phase 2/3 study (NCT03570749), and
  • BRAVE-AA2, a phase 3 study (NCT03899259).2-4

Assessments of common treatment-emergent adverse events (TEAEs) in the BRAVE-AA trials were reported in 3 integrated safety datasets including the

  • 36-week placebo-controlled BARI AA dataset with patients exposed to placebo, baricitinib 2 mg, and baricitinib 4 mg from randomization to week 36
  • extended BARI AA dataset with patients exposed to baricitinib 2 mg or 4 mg from randomization to dose or treatment change, or data cutoff, and
  • All-BARI-AA dataset with all patients exposed to any baricitinib dose (1-mg, 2-mg, or 4-mg) at any time during the studies.5

Safety data were integrated from the BRAVE-AA1 phases 2 and 3 cohorts (data cutoff May 22, 2023) and from BRAVE-AA2 (data cutoff May 8, 2023). Data cutoff represents all patients who either completed at least 152 weeks of the study or discontinued from the trial.6

More details on patient exposure and censoring rules in each dataset are provided in Integrated Analysis Datasets Used to Evaluate Safety in Alopecia Areata Clinical Trials.

The most common (≥5%) TEAEs reported in the All BARI AA analyses set were

  • coronavirus disease 2019 (COVID-19)
  • upper respiratory tract infection
  • headache
  • nasopharyngitis
  • acne
  • urinary tract infection (UTI), and
  • blood creatine phosphokinase (CPK) increase.6

Common TEAEs are defined as those reported at a frequency of greater than or equal to 2%, before rounding of patients in any treatment group, including placebo (see Common Treatment-Emergent Adverse Events Occurring in ≥2% in Any Group).

36-Week Placebo-Controlled Period

Treatment-emergent adverse events that were more frequent in the baricitinib 2-mg and baricitinib 4-mg group compared with placebo were

  • acne
  • UTI, and
  • vulvovaginal candidiasis.5,6

The TEAEs that were reported more frequently in baricitinib 4-mg compared with placebo were

  • blood CPK increased
  • fatigue, and
  • folliculitis.6

All-BARI-AA Analysis Set

With longer exposure, no clinically relevant increases in adverse event incidence rates were observed compared to rates during the placebo-controlled period, except for COVID-19, representing the conduct of the studies during the pandemic.6

Analysis Set

Description

36-Week placebo-controlled BARI AA

Assesses BARI 4 mg, BARI 2 mg, and placebo.

Includes patients from the phase 2/3 BRAVE-AA1 and phase 3 BRAVE-AA2 studies who were randomized to

  • BARI 4 mg (n=540, PYE=363.4)
  • BARI 2 mg (n=365, PYE=240.6), or
  • placebo (n=371, PYE=243.2).

Evaluation time period included randomization to week 36.

Extended BARI AA

Assesses BARI 4 mg and BARI 2 mg including extended evaluations.

Includes patients from the phase 2/3 BRAVE-AA1 and phase 3 BRAVE-AA2 studies who were randomized to

  • BARI 4 mg (n=565, PYE=1106.70), or
  • BARI 2 mg (n=383, PYE=523.25).

Evaluation time period included randomization up to data cutoff, May 22, 2023 for BRAVE-AA1, and May 8, 2023 for BRAVE-AA2. Data were censored after a patient was switched to another dose or treatment.

All BARI AA

No between-group assessments.

Includes 1303 (total PYE=2789.69) patients from the phase 2/3 BRAVE-AA1 and phase 3 BRAVE-AA2 studies who were exposed to any BARI dose, including

  • BARI 4 mg (n=1001, PYE=1912.55)
  • BARI 2 mg (n=595, PYE=887.69), or
  • BARI 1 mg (n=28, PYE=14.6).

Evaluation time period included any time points during the studies either from randomization or from switch or rescue from placebo.

Abbreviations: AA = alopecia areata; BARI = baricitinib; PYE = patient-years of exposure.
