Baricitinib is associated with an increased rate of infections such as upper respiratory tract infections compared to placebo. In treatment naïve patients, combination with methotrexate resulted in increased frequency of infections compared to baricitinib monotherapy.1
The risks and benefits of treatment with baricitinib should be carefully considered prior to initiating therapy in patients with active, chronic or recurrent infections.1
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.1
COVID-19 is an active respiratory disease, which is typically mild and may also lead to acute respiratory distress syndrome which can be lethal. Baricitinib should not be used during active COVID-19 infection and may be resumed after medical consultation and infection is resolved.
Upper Respiratory Tract Infections
Upper respiratory tract infections were very commonly (≥10%) reported adverse events in RA BARI clinical trials.2

Abbreviations: BARI = baricitinib; EAIR = exposure adjusted incidence rate; IR = incidence rate; PYE = patient-years of exposure; TE = treatment emergent.
a The 7-study pooled dataset included patients with RA randomized to BARI 4 mg (N=1142, PYE=471.8) or placebo (N=1215, PYE=450.8) from 3 phase 2 studies and 4 phase 3 studies. Patients in the placebo group could have been taking background MTX or other conventional DMARDs. Data from BARI 2 mg (N=479, PYE=185.8) is derived from 4 of these studies in which both BARI 2 mg and BARI 4 mg were options during randomization.
b Includes acute sinusitis, epiglottitis, laryngitis, nasopharyngitis, oropharyngeal pain, pharyngitis, pharyngotonsillitis, rhinitis, sinusitis, sinobronchitis, tonsillitis, tracheitis, and upper respiratory tract infection.
Serious Infections in Rheumatoid Arthritis Clinical Trials
The All BARI RA analysis set included 3770 patients with RA who received BARI at a variety of doses from 1 phase 1, 3 phase 2, and 5 phase 3 studies (RA-BEGIN, RA-BEAM, RA-BUILD, RA-BEACON, RA-BALANCE). Data includes a long-term extension study (RA-BEYOND) with
Of the 3770 patients who received BARI in the RA clinical trials through 13 February 2018, there were 283 TE serious infections with an IR per 100 PYE, censored at time of event, of 2.8. The most frequent serious infections reported were
pneumonia (n=52, EAIR 0.5)
HZ (n=35, EAIR 0.4)
urinary tract infection (n=21, EAIR 0.2)
cellulitis (n=15, EAIR 0.2)
sepsis (n=18 including 14 cases of sepsis and 4 cases of urosepsis), and
gastroenteritis (n=13, EAIR 0.13).2-4
Clinical Factors Associated with Serious Infection
A large group of clinical factors with the potential to affect the risk of serious infection was evaluated using Cox models and data from the All BARI RA dataset through 01 January 2016. The 5 independent risk factors identified for serious infection were
prior biologic use
Asian region of study enrollment, excluding Japan
non-normal body mass index, and
concomitant corticosteroid use.5
Additionally, increasing grades of lymphopenia were associated with an increase in frequency of any TE infection and serious infection in BARI-treated patients.2
Background information related to infection
Infections belong to the known adverse drug reactions of baricitinib:1
upper respiratory tract infection (combined term: acute sinusitis, epiglottitis, laryngitis, nasopharyngitis, oropharyngeal pain, pharyngitis, pharyngotonsillitis, rhinitis, sinusitis, tonsillitis, tracheitis, upper respiratory tract infection)
Herpes simplex (combined term: eczema herpeticum, herpes simplex, ophthalmic herpes simplex, oral herpes)
Urinary tract infections
The most commonly reported adverse drug reactions (ADRs) occurring in ≥ 2 % of patients treated with baricitinib monotherapy or in combination with conventional synthetic DMARDs were increased LDL cholesterol (33.6 %), upper respiratory tract infections (14.7 %) and nausea (2.8 %). Infections reported with Baricitinib treatment included Herpes zoster.1
In controlled studies, for up to 16 weeks, the incidence rate of all infections (rate of patients with ≥ 1 event per 100 patient-years of exposure) was 101 with baricitinib compared to 83 in the placebo group. Most infections were mild to moderate in severity. In studies which included both doses, infections were reported in 31.9 %, 28.8 % and 24.1 % of patients up to 16 weeks in the 4 mg, 2 mg and placebo groups, respectively. Reporting rates for baricitinib compared to placebo for the infection-related ADRs were: Upper respiratory tract infections (14.7 % vs. 11.7 %), urinary tract infections (3.4 % vs. 2.7 %), gastroenteritis (1.6 % vs. 0.8 %), herpes simplex (1.8 % vs. 0.7 %), and herpes zoster (1.4 % vs. 0.4 %). In treatment-naïve patients, for up to 52 weeks, the frequency of upper respiratory tract infections was greater for the combination treatment of methotrexate and baricitinib (26.0 %) compared to methotrexate alone (22.9 %) or baricitinib alone (22.0 %). The rate of serious infections with baricitinib (1.1 %) was similar to placebo (1.2 %). For baricitinib, the most common serious infections were herpes zoster, and cellulitis. The rate of serious infections remained stable during long term exposure. The overall incidence rate of serious infections in the clinical trial programme was 3.2 per 100 patient-years.1
The treating physician may use the information provided, the patient’s prior medical history and concomitant medications, and other individual factors, in formulating an assessment and approach. The treating physician should consider potential risks and benefits of treatment options, and monitor appropriately.

Baricitinib is indicated for the treatment of moderate to severe active rheumatoid arthritis in adult patients who have responded inadequately to, or who are intolerant to one or more disease-modifying anti-rheumatic drugs. Baricitinib may be used as monotherapy or in combination with methotrexate.1
Baricitinib is indicated for the treatment of moderate to severe atopic dermatitis in adult patients who are candidates for systemic therapy.1
