Adverse Reactions
Summary of safety profile: The most commonly reported adverse drug reactions (ADRs) occurring in ≥ 2 % of patients treated with Olumiant 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 Olumiant treatment included Herpes zoster.
Tabulated list of adverse reactions: A total of 3,464 patients were treated with Olumiant in clinical studies in rheumatoid arthritis representing 4214 patient-years of exposure. Of these, 2166 rheumatoid arthritis patients were exposed to Olumiant for at least one year. Six placebo-controlled studies were integrated (997 patients on 4 mg once daily and 1070 patients on placebo) to evaluate the safety of Olumiant in comparison to placebo for up to 16 weeks after treatment initiation. (See Table 5.)

Description of selected adverse reactions: Nausea: In treatment-naïve patients, through 52 weeks, the frequency of nausea was greater for the combination treatment of methotrexate and Olumiant (9.3 %) compared to methotrexate alone (6.2 %) or Olumiant alone (4.4 %). Nausea was most frequent during the first 2 weeks of treatment.
Infections: 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 Olumiant 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 Olumiant 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 Olumiant (26.0 %) compared to methotrexate alone (22.9 %) or Olumiant alone (22.0 %). The rate of serious infections with Olumiant (1.1 %) was similar to placebo (1.2 %). For Olumiant, 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.
Hepatic transaminase elevations: In controlled studies, for up to 16 weeks, alanine transaminase (ALT) and aspartate transaminase (AST) elevations ≥ 3 x upper limit of normal (ULN) were observed in 1.4 % and 0.8 % of patients treated with Olumiant, compared to 1.0 % and 0.8 % respectively of patients treated with placebo. Most cases of hepatic transaminase elevations were asymptomatic and transient.
In treatment-naïve patients, the combination of Olumiant with potentially hepatotoxic medicinal products, such as methotrexate, resulted in increased frequency of these elevations. For up to 52 weeks, the frequency of ALT and AST elevations ≥ 3 x ULN were greater for the combination treatment of methotrexate and Olumiant (7.5 % and 3.8 %) compared to methotrexate alone (2.9 % and 0.5 %) or Olumiant alone (1.9 % and 1.3 %).
The pattern and incidence of elevation in ALT/AST remained stable over time including in the long-term extension study.
Lipid elevations: Baricitinib treatment was associated with dose-dependent increases in lipid parameters including total cholesterol, triglycerides, LDL cholesterol, and HDL cholesterol. There was no change in the LDL/HDL ratio. Elevations were observed at 12 weeks and remained stable thereafter at a higher value than baseline including in the long-term extension study. In controlled studies, for up to 16 weeks, the following rates were observed for Olumiant vs. placebo: Increased total cholesterol ≥ 5.17 mmol/L: 49.1 % vs. 15.8 %, respectively.
Increased LDL cholesterol ≥ 3.36 mmol/L: 33.6 % vs. 10.3 %, respectively.
Increased HDL cholesterol ≥ 1.55 mmol/L: 42.7 % vs. 13.8 %, respectively.
Increased triglycerides ≥ 5.65 mmol/L: 0.4 % vs. 0.5 %, respectively.
In studies which included both doses, a dose-relationship was observed with increased total cholesterol ≥ 5.17 mmol/L reported in 48.8 %, 34.7 % and 17.8 % of patients up to 16 weeks in the 4 mg, 2 mg and placebo groups, respectively.
Elevations in LDL cholesterol decreased to pre-treatment levels in response to statin therapy.
Creatine phosphokinase (CPK): In controlled studies, for up to 16 weeks, increases in CPK values were common. Significant increases (> 5 x ULN) occurred in 0.8 % of patients treated with Olumiant and 0.3 % of patients treated with placebo. A dose relationship was observed with CPK elevations ≥ 5 x ULN of normal reported in 1.5 %, 0.8 % and 0.6 % of patients at 16 weeks in the 4 mg, 2 mg and placebo groups, respectively. Most cases were transient and did not require treatment discontinuation. In clinical trials, there were no confirmed cases of rhabdomyolysis. Elevations of CPK were observed at 4 weeks and remained stable at a higher value than baseline thereafter including in the long-term extension study.
Neutropaenia: In controlled studies, for up to 16 weeks, decreases in neutrophil counts below 1 x 109 cells/L occurred in 0.3 % of patients treated with Olumiant compared to 0 % of patients treated with placebo. There was no clear relationship between decreases in neutrophil counts and the occurrence of serious infections. However, in clinical studies, treatment was interrupted in response to ANC < 1 x 109 cells/L. The pattern and incidence of decreases in neutrophil counts remained stable at a lower value than baseline over time including in the long-term extension study.
Thrombocytosis: In controlled studies, for up to 16 weeks, increases in platelet counts above 600 x 109 cells/L occurred in 2.0 % of patients treated with Olumiant 4 mg and 1.1 % of patients treated with placebo. No association was observed between increased platelet counts and adverse events of a thrombotic nature. The pattern and incidence of increases in platelet counts remained stable at a higher value than baseline over time including in the long term extension study.
Reporting of suspected adverse reactions: Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions to the Drug Office, Department of Health.
