Olumiant® ▼ (baricitinib): Pre-existing Parasitic Infections

The safety of baricitinib in patients with moderate to severe atopic dermatitis and preexisting parasitic infection have not been studied.

Overview of BREEZE-AD Phase 3 Placebo-Controlled Clinical Trials

The efficacy and safety of BARI has been evaluated in the following placebo-controlled trials in adult patients with moderate to severe AD

  • BREEZE-AD1 (N=624) and BREEZE-AD2 (N=615) compared BARI 1 mg, 2 mg, or 4 mg monotherapy to placebo in adult patients with inadequate response to TCS.1

  • BREEZE-AD4 (N=500) compared BARI 1 mg, 2 mg, or 4 mg in combination with TCS vs placebo with TCS in adult patients who were inadequate responders to, intolerant of, or contraindicated for cyclosporine.2

  • BREEZE-AD5 (N=440) compared BARI 1 mg or 2 mg monotherapy to placebo in adult patients with inadequate response to TCS.3

  • BREEZE-AD7 (N=329) compared BARI 2 mg or 4 mg in combination with TCS vs placebo with TCS in adult patients with inadequate response to topical medications.4

Note: BARI 1 mg was studied in pivotal trials, however it is not approved. Please refer to section 4.2 of the Olumiant Summary of Product Characteristics for approved dosage.

BREEZE-AD Clinical Trial Criteria

Patients were excluded from enrollment in the BREEZE-AD studies if they had a current or recent clinically serious parasitic infection within 4 weeks of randomization that, in the opinion of the investigator, would pose an unacceptable risk to the patient if participating in the study.5

Patients With Atopic Dermatitis and Preexisting Parasitic Infections

An analysis of the efficacy and safety of BARI in patients with moderate to severe AD and preexisting parasitic infections has not been conducted.

One patient (0.4%) reported a preexisting lice infestation in the placebo arm of the BARI monotherapy study (BREEZE-AD1) and 1 patient (1.1%) reported a preexisting parasite stool test positive in the BARI 4 mg arm of the BARI in combination with TCS study (BREEZE-AD4). No patients reported preexisting parasitic infections in the pivotal phase 3 trials BREEZE-AD2, BREEZE-AD5, and BREEZE-AD7.5

Warnings and Precautions Related to Infections

Baricitinib is associated with an increased rate of infections such as upper respiratory tract infections compared to placebo. In rheumatoid arthritis clinical studies, in treatment naïve patients, combination with methotrexate resulted in increased frequency of infections compared to baricitinib monotherapy.6

The risks and benefits of treatment with baricitinib should be carefully considered prior to initiating therapy in patients with active, chronic or recurrent infections.6

If an infection develops, the patient should be monitored carefully and baricitinib therapy should be temporarily interrupted if the patient is not responding to standard therapy. Baricitinib treatment should not be resumed until the infection resolves.6
