The table shows the side effects found in patients with CD2 when taking the drug Onglis® at a dose of 5 mg during clinical trials. The overall incidence of adverse events with the use of the Onglis® 5 mg preparation in monotherapy and in the mode of addition to therapy with metformin, thiazolidinedione or glibenclamide was comparable to that in the placebo group. Scale of adverse reactions frequency: very often (>1/10); often (>1/100, <1/10); infrequently (>1/1000, <1/100); rarely (>1/10000, <1/1000); very rarely (<1/10000).
The incidence of hypersensitivity reactions noted by the 24th week of therapy was 1.5% in patients receiving Ongliza® 5 mg and 0.4% in patients receiving placebo. Hypersensitivity reactions that occurred in patients taking the drug Ongliza® did not require hospitalization and were regarded by the treating physicians as not posing a life threat.
Side effects of the drug Ongliza® with combined therapy in studies of glycemic control
In a study on the combined use of saxagliptin and glibenclamide, the incidence of confirmed hypoglycemic episodes was 0.8% in the 5 mg saxagliptin group and 0.7% in the placebo group. The incidence of confirmed episodes of hypoglycemia in patients,who received Onglis® 5 mg in two studies of saxagliptin in the monotherapy regimen, a study on combined therapy with saxagliptin and metformin, and in a study on the combined use of saxagliptin and thiazolidinediones, was comparable to that of placebo.
In a study on the use of a combination of saxagliptin and insulin, the overall incidence of hypoglycaemia was 18.4% in the 5 mg group of saxagliptin and 19.9% in the placebo group, with the incidence of confirmed episodes of hypoglycemia, accompanied by symptoms, were 5.3% and 3.3%, respectively.
In a study on the use of saxagliptin in combination with metformin and sulfonylureas, the overall incidence of hypoglycaemia was 10.1% in patients receiving Onglis® 5 mg and 6.3% in patients receiving placebo, the incidence of confirmed hypoglycemia was 1.6% and 0%, respectively.
In a study on the use of saxagliptin in combination with thiazolidinediones, the incidence of peripheral edema was higher in the 5 mg saxagliptin group than in the placebo group (8.1% and 4.3%, respectively).Peripheral edema was mild or moderate and did not lead to cessation treatment. The incidence of peripheral edema in patients taking Onglys® 5 mg in clinical trials of monotherapy with saxagliptin and combined therapy with metformin or glibenclamide, was comparable to that of placebo (1.7% and 2.4%, respectively).
With starting combination therapy with saxagliptin at a dose of 5 mg and metformin, cases of nasopharyngitis and headache were often noted. The incidence of nasopharyngitis was higher with combined therapy (6.9%) compared with monotherapy with saxagliptin 10 mg (4.2%) and metformin (4.0%). Headache was noted more often in the group of patients on combined therapy with metformin and saxagliptin 5 mg (7.5%) compared with the groups of monotherapy with saxagliptin 10 mg (6.3%) and metformin (5.2%).
Side effects of the drug Onglya® in the SAVOR study
In the SAVOR study, 8240 patients received an Onglya® preparation at a dose of 2.5 mg or 5 mg once daily, and 8173 patients received a placebo. The average duration of therapy with the drug Ongliza®, regardless of interruptions in treatment, was 1.8 years.In 3698 patients (45%), the duration of therapy with the drug Onglysa was 2-3 years.
The overall incidence of adverse events in this study in the group of patients taking Onglis® (72.5%) was comparable to the incidence of adverse events in the placebo group (72.2%). The frequency of withdrawal of therapy due to adverse events was comparable in patients taking Onglis® (4.9%) and placebo (5%).
In the SAVOR study, the effect of the drug Ongliza® on the incidence of cardiovascular complications was evaluated. It has been shown that the addition of Onglys® to therapy does not increase the risk of cardiovascular complications (such as cardiovascular mortality, nonfatal myocardial infarction, nonfatal ischemic stroke) in patients with DM2 compared with placebo (RR 1.00, 95% CI 0.89, 1.12, P <0.001 for
hypothesis comparability of saxagliptin and placebo).
The incidence of pancreatitis confirmed in accordance with the study protocol was 0.3% in the saxagliptin and placebo groups in the population of all randomized patients. The incidence of hypersensitivity reactions was 1.1% in the Onglis® group and placebo.
Hypoglycaemia
The overall incidence of hypoglycemia (noted in patient diaries) in the SAVOR trial was 17.1% in the Onglis ® group and 14.8% in the placebo group. Proportion of patients who experienced severe hypoglycemia against the background of therapy (hypoglycemia, requiring help
third parties) was higher in the saxagliptin group than in the placebo group (2.1% and 1.6%, respectively).
The increased risk of hypoglycemia in general, as well as severe hypoglycemia in the saxagliptin group, was mainly observed in patients receiving sulfonylurea preparations, but not in patients receiving insulin or
metformin as a basic therapy. The increased risk of hypoglycemia in general, as well as severe hypoglycemia, is mainly observed in patients with a baseline HbAlc <7%.
Postmarketing applicationDuring the post-marketing application of saxagliptin the following side effects are recorded: acute pancreatitis and reactions
hypersensitivity, including anaphylaxis, angioedema, rash and hives. It is impossible to reliably estimate the frequency of development of these phenomena, since messages were received spontaneously from a population of an unidentified size (see Fig.sections "Contraindications" and "Special instructions").
Laboratory research
In clinical studies, the frequency of changes in laboratory parameters when taking saxagliptin at a dose of 5 mg and placebo was comparable. There was a slight decrease in the number of lymphocytes, with the average absolute number of lymphocytes remaining stable and within the normal range with daily intake of saxagliptin for up to 102 weeks. The decrease in the number of lymphocytes was not accompanied by clinically significant undesirable reactions. The clinical importance of reducing the number of lymphocytes on the background of therapy with saxagliptin is not known. In the SAVOR study, a decrease in the number of lymphocytes in the Onglis ® group was noted in 0.5% of patients, in the placebo group in 0.4% of patients.
