Adverse Reactions
Summary of the safety profile: The following risks, including appropriate action to be taken, are discussed in greater detail in Precautions: cardiac failure events, hypertension, thyroid dysfunction, arterial thromboembolic events, venous thromboembolic events, elevation of haemoglobin or haematocrit, haemorrhage, gastrointestinal perforation and fistula formation, wound healing complications, PRES, proteinuria, and elevation of liver enzymes.
The most common (≥20%) adverse reactions observed following treatment with axitinib were diarrhoea, hypertension, fatigue, decreased appetite, nausea, weight decreased, dysphonia, palmar-plantar erythrodysaesthesia (hand-foot) syndrome, haemorrhage, hypothyroidism, vomiting, proteinuria, cough, and constipation.
Tabulated list of adverse reactions: Table 2 presents adverse reactions reported in a pooled dataset of 672 patients who received axitinib in clinical studies for the treatment of patients with RCC (see Pharmacology: Pharmacodynamics under Actions). Post-marketing adverse reactions identified in clinical studies are also included.
The adverse reactions are listed by system organ class, frequency category and grade of severity. Frequency categories are defined as: very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), and not known (cannot be estimated from the available data). The current safety database for axitinib is too small to detect rare and very rare adverse reactions.
Categories have been assigned based on absolute frequencies in the pooled clinical studies data. Within each system organ class, adverse reactions with the same frequency are presented in order of decreasing seriousness. (See Table 2.)

Thyroid stimulating hormone (TSH) increased was reported as an adverse reaction in 5.3% of patients receiving axitinib. During routine laboratory assessments, in patients who had TSH < 5 μU/mL before treatment, elevations of TSH to ≥10 μU/mL occurred in 32.2% of patients receiving axitinib.
In pooled clinical studies with axitinib (N = 672) for the treatment of patients with RCC, hypothyroidism was reported in 24.6% of patients receiving axitinib. Hyperthyroidism was reported in 1.6% of patients receiving axitinib.
Venous embolic and thrombotic events (see Precautions): In a controlled clinical study with axitinib for the treatment of patients with RCC, venous embolic and thrombotic adverse reactions were reported in 3.9% of patients receiving axitinib, including pulmonary embolism (2.2%), retinal vein occlusion/thrombosis (0.6%) and deep vein thrombosis (0.6%). Grade 3/4 venous embolic and thrombotic adverse reactions were reported in 3.1% of patients receiving axitinib. Fatal pulmonary embolism was reported in one patient (0.3%) receiving axitinib.
In pooled clinical studies with axitinib (N = 672) for the treatment of patients with RCC, venous embolic and thrombotic events were reported in 2.8% of patients receiving axitinib. Grade 3 venous embolic and thrombotic events were reported in 0.9% of patients. Grade 4 venous embolic and thrombotic events were reported in 1.2% of patients. Fatal venous embolic and thrombotic events were reported 0.1% patients receiving axitinib.
Arterial embolic and thrombotic events (see Precautions): In a controlled clinical study with axitinib for the treatment of patients with RCC, arterial embolic and thrombotic adverse reactions were reported in 4.7% of patients receiving axitinib, including myocardial infarction (1.4%), transient ischemic attack (0.8%) and cerebrovascular accident (0.6%). Grade 3/4 arterial embolic and thrombotic adverse reactions were reported in 3.3% of patients receiving axitinib. A fatal acute myocardial infarction and cerebrovascular accident was reported in one patient each (0.3%). In monotherapy studies with axitinib (N = 850), arterial embolic and thrombotic adverse reactions (including transient ischemic attack, myocardial infarction, and cerebrovascular accident) were reported in 5.3% of patients receiving axitinib.

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 via the national reporting system.
