Disturbances from the musculoskeletal system: often - backache.
Disorders from the digestive system: infrequently gastroesophageal reflux disease.
General disorders and reactions at the site of administration: often - general weakness /increased fatigue.
Reactions at the injection site were observed in 1.2% of patients treated with Ilaris ® in clinical trials.
Changes in laboratory indicators
General blood analysis
Reducing the number of leukocytes <0.8 × 109/ l of the lower limit of the norm was noted in 6.7% of patients treated with Ilaris ®, compared with 1.4% of patients who received triamcinolone. Reduction of the absolute number of neutrophils below 1 x 109 / l was observed in 2% of patients in comparative studies on gouty arthritis. There were also isolated cases of a decrease in the number of neutrophils below 0.5 x 109 / l.
In 12.7% of cases, against the background of Kanakinumab therapy, there was a slight and transient decrease in the number of platelets (ranging from 75 x 109/ l) to the lower limit of the norm (in the reference drug, this decrease was observed in 7.7% of cases).
Uric acid
On the background of therapy with kanakinumab, there is a transient increase in the concentration of uric acid (by about 0.6 mg / dL). Ilaris® does not reduce the ability of antidotal drugs to reduce the concentration of uric acid when combined.
Aspartate aminotransferase / alanine aminotransferase (AST / ALT)
On the background of Kanakinumab therapy, it is possible to develop a mild to moderate increase in AST / ALT activity.
Triglycerides
On the background of therapy with kanakinumab, on average, there is an increase in concentration triglycerides in blood plasma at 33.5 mg / dl, and in the group of triamcinolone - a slight decrease of 3.1 mg / dl.Increase in triglyceride concentration by more than 5 times (compared with the upper limit of normal) was observed in 2.4% of cases in the group of application of kanakinumab and in 0.7% of cases in the group of triamcinolone. The clinical significance of this observation is unknown.
Cryopyrin-associated Periodic Syndrome
Infectious and parasitic diseases: very often - nasopharyngitis; often - urinary tract infections; infection of the upper respiratory tract, viral infection.
Disturbances from the nervous system: Often dizziness / vertigo.
Disturbances from the skin and subcutaneous tissues: Often - reaction in place administration of the drug **.
* Vertigo symptoms, in some cases, were considered as serious AEs, all episodes of vertigo were resolved, despite continued therapy with the drug.
** An adverse event (AE) was detected using a questionnaire for a doctor.
In the course of long, open studies with escalation of the dose, there was an increase in the incidence of infectious diseases (gastroenteritis, respiratory tract infections and upper respiratory tract infections), nausea and dizziness in a group of patients receiving doses of 600 mg or 8 mg / kg, compared with groups receiving other doses of the drug.
Changes in laboratory indicators
General blood analysis
When using the drug in clinical studies in patients with CAPS there was an increase in hemoglobin and a decrease in the number of leukocytes, neutrophils and platelets. However, these changes were probably associated with a decrease the severity of the inflammatory process against the background of drug therapy and did not have clinical significance.
Enzymes of the liver
In rare cases in patients with CAPS, who received treatment with the drug, there was an increase in the activity of "liver" transaminases.
Bilirubin
In a number of cases, against the background of drug therapy in patients with CAPS There was an asymptomatic insignificant increase in serum bilirubin, not accompanied by an increase in the activity of "liver" transaminases.
SJUIA
Infectious and parasitic diseases: very often - infections (in particular, nasopharyngitis, viral infections of the upper respiratory tract, pneumonia, rhinitis, pharyngitis, tonsillitis, sinusitis, urinary tract infections, gastroenteritis, viral infection).
Disorders from the digestive system: very often - pain in the upper abdomen.
Disturbances from the skin and subcutaneous tissues: very often - a reaction at the site of administration of the drug of mild severity *, often - a reaction at the site of administration of the drug of moderate severity *.
* - did not lead to the termination of the study.
Changes in laboratory indicators
General blood analysis
Decrease in the number of leukocytes <0.8 × 109/ l of the lower limit of normal was observed in 10.4% of patients treated with Ilaris®, compared to 4.0% in the placebo group.
Transient decrease in the absolute number of neutrophils <1x109/ l was observed in 6.0% of patients treated with Ilaris®, compared with 2.0% in the placebo group. There was only one case of a decrease in the absolute number of neutrophils <0.5x109/ l when treated with Ilaris®.
Moderate and transient decrease in the range from 75 х109/ l to the lower limit of the norm thrombocytes was noted in 6.3% of patients receiving Ilaris®, compared with 2.0% in the placebo group.
Enzymes of the liver
Three-fold increase in ALT and / or ACT in comparison with the upper limit of the norm was noted in 4.1 % patients, who received treatment with Ilaris®, compared with 2.0% in the placebo group. At the subsequent examination normalization of parameters was noted.
Hypersensitivity reactions
When Ilaris ® was used in clinical trials, adverse events were reported by doctors as hypersensitivity reactions. In most cases, these reactions were mild. When using the drug, there was no development of anaphylactoid or anaphylactic reactions. However, when prescribing Ilaris®, one can not exclude the risk of developing severe hypersensitivity reactions that can occur when injected with preparations of protein origin. Patients treated with Ilaris® about gouty arthritis, CAPS and SJUIA antibodies to the drug were detected in 1.5%, 3% and 2% of cases, respectively. Interrelations between the formation of antibodies, clinical response and the development of adverse events have not been identified.
Application in patients aged < 18 years (patients with CAPS)
Children aged 2-17 years did not have clinically significant differences in the safety and tolerability of Ilaris®, including the overall incidence and severity of infections, compared with the general population of patients.Most often, children had upper respiratory tract infections.
Use in patients > 65 years old
There were no differences in the safety profile of the drug in this group of patients.
The patient should be informed of the need to consult a doctor if severe adverse reactions develop, including those not specified in the instructions.
