Special Instructions

Application in patients with impaired renal function

Renal function should be evaluated before starting therapy with Forsiga and further if clinically indicated.

The trials of efficacy and safety of the drug Forsiga did not include patients with rCF less than 25 ml/min/1.73 m². The use of the drug Forsiga is contraindicated in patients on hemodialysis.

The use of the drug Forcega to improve glycemic control in adult patients with type 2 diabetes mellitus with a pSFR less than 45 ml/min/1.73 m² is not recommended due to possible ineffectiveness of the drug in this population due to the mechanism of pharmacological action of dapagliflozin.

The use of Forsiga is not recommended for the treatment of chronic kidney disease in patients with polycystic kidney disease or in patients who require or have recently received immunosuppressive therapy for renal failure. Dapagliflozin is not expected to be effective in these patient groups.

In one study in patients with mild-to-moderate renal impairment DM2 (pSF < 60 mL/min/1.73 m²), adverse reactions in the form of increased parathyroid hormone concentrations and arterial hypotension were seen in a higher proportion of patients in the dapagliflozin group than in the placebo group.

Application in patients with hepatic impairment

Limited data on the use of the drug in patients with hepatic impairment have been obtained in clinical studies. Exposure to dapagliflozin is increased in patients with severe hepatic impairment (see sections “Dosage and administration”, “Caution” and “Pharmacokinetics”).

CPU Decrease

The drug Forciga may cause decreased CPR, which may sometimes manifest as symptomatic arterial hypotension or acute transient changes in creatinine concentration. During post-registration use of SGLT2 inhibitors, including Forsiga, cases of acute kidney damage were observed in patients with DM2, some of which required hospitalization and dialysis. In patients with impaired renal function (rCF less than 60 ml/min/1.73 m²), elderly patients or patients taking “loop” diuretics an increased risk of decreased BOD or arterial hypotension may be noted. Before starting therapy with Forciga in patients with one or more of these characteristics, it is necessary to assess the CPR and renal function. After initiation of therapy, patients should be monitored for possible signs and symptoms of arterial hypotension and renal function should be monitored.

Application in patients at risk of arterial hypotension

. According to the mechanism of action, dapagliflozin increases diuresis, which may lead to a slight decrease in blood pressure noted in clinical studies (see section “Pharmacodynamics”). Diuretic effect may be more pronounced in patients with very high blood glucose concentrations.

Waution should be exercised in patients for whom dapagliflozin-induced reduction of blood pressure may be a risk, e.g., in patients receiving hypotensive therapy, with a history of hypotension or in elderly patients.

Ketoacidosis in patients with diabetes

. There have been reports of cases of ketoacidosis, including diabetic ketoacidosis, in patients with type 1 and type 2 diabetes taking Forciga and other SGLT2 inhibitors. The drug Forsiga is not indicated for the treatment of patients with type 1 diabetes mellitus.

Patients taking Forsiga with signs and symptoms suggestive of ketoacidosis, including nausea, vomiting, abdominal pain, malaise, and shortness of breath, should be evaluated for ketoacidosis, even with blood glucose concentrations below 14 mmol/L. If ketoacidosis is suspected, consideration should be given to withdrawing or temporarily discontinuing Forciga, and the patient should be evaluated immediately.

Factors predisposing to the development of ketoacidosis include low functional activity of beta cells due to pancreatic dysfunction (e.g., type 1 diabetes, pancreatitis or a history of pancreatic surgery), decreased insulin dose, reduced caloric intake or increased insulin requirement due to infections, disease or surgery, and alcohol abuse. Forciga should be used with caution in these patients.

Necrotizing fasciitis of the perineum (Fournier’s gangrene)

. Post-histamine cases of necrotizing fasciitis of the perineum (Fournier’s gangrene) have been reported in women and men taking SGLT2 inhibitors (see

Section “Side effects”). This is a rare, potentially serious and life-threatening condition that requires emergency surgery and antibiotics. Patients should consult a physician if they experience symptoms of pain, sensitivity to touch, erythema or swelling in the genital or perineal area accompanied by fever and malaise. It is known that either a urogenital infection or a perineal abscess may precede necrotizing fasciitis.

If Fournier’s gangrene is suspected, the use of Forciga should be discontinued and immediate treatment (including antibiotics and surgery) initiated.

Urinary tract infections

. Cases of serious urinary tract infections, including urosepsis and pyelonephritis, that required hospitalization have been reported in patients taking SGLT2 inhibitors, including Forciga. Therapy with SGLT2 inhibitors increases the risk of urinary tract infections. Patients should be monitored for possible signs and symptoms of urinary tract infections and, if indicated, treatment should be started immediately (see section “Side effects”). If pyelonephritis or urosepsis is treated, temporary withdrawal of therapy with dapagliflozin should be considered.

Lower limb amputation

. An increase in lower limb amputation (primarily toes) has been observed in an ongoing long-term clinical trial in DM2 with another SGLT2 inhibitor. It is unknown whether this is an effect of SGLT2 class drugs. It is important to recommend continuous preventive foot care for diabetic patients taking SGLT2 inhibitors.

Chronic Heart Failure

The experience with dapagliflozin in patients with NYHA functional class IV chronic heart failure is limited.

Evaluations of urine test results

Due to the mechanism of action of the drug, urine test results for glucose in patients taking Forciga will be positive.

Influence on 1,5-Anhydroglucitol determination

. Assessment of glycemic control using 1,5-anhydroglucitol determination is not recommended because measurement of 1,5-anhydroglucitol is an unreliable method for patients taking SGLT2 inhibitors. Alternative methods should be used to assess glycemic control.

Hypoglycemia on concomitant use of insulin and secretion stimulants insulin

Insulin and insulin secretion stimulants may cause hypoglycemia. The drug Forcega may increase the risk of hypoglycemia when used in combination with insulin or insulin secretion stimulants (see section “Side effects”). It may be necessary to reduce the dose of insulin or insulin secretion stimulants to reduce the risk of hypoglycemia when they are used concomitantly with the drug Forsiga.

Fungal genital infections

Forsiga increases the risk of fungal genital infections. Patients with a history of fungal genital infections are more likely to develop these infections (see section “Side effects”). Patients should be monitored and appropriate treatment in case of such infections.

Influence on the ability to drive and operate vehiclesThere have been no studies on the effect of dapagliflozin on the ability to drive and operate vehicles.

Description of individual adverse reactions

.Vulvovaginitis, balanitis, and related genital infections

. In pooled safety data from 13 studies, vulvovaginitis, balanitis, and related genital infections were reported in 5.5% and 0.6% of patients taking dapagliflozin 10 mg and placebo, respectively. Most infections were mild to moderate; the initial course of standard therapy was effective, and patients rarely discontinued dapagliflozin. These infections were more frequent in women (8.4% and 1.2% with dapagliflozin and placebo, respectively), and patients with a history of such infections were more likely to have recurrent infections.

In the DECLARE trial, the number of patients with serious adverse events in the form of genital infections was small and balanced: 2 (< 0.1%) each in the dapagliflozin group and placebo group.

In the DAPA-HF study, there were no patients with serious adverse events in the form of genital infections in the dapagliflozin group; in the placebo group, a serious adverse event was reported in 1 patient. In the dapagliflozin group, 7 (0.3%) patients had adverse events leading to discontinuation of treatment due to genital infections, and no patient in the placebo group.

In the DAPA-CKD study, there were 3 (0.1%) patients with serious adverse events in the form of genital infections in the dapagliflozin group and no patients with such events in the placebo group. In the dapagliflozin group, 3 (0.1%) patients had adverse events leading to discontinuation of treatment due to genital infections, while there were no patients with such events in the placebo group. No serious adverse events or adverse events leading to treatment discontinuation due to genital infections were reported in patients without diabetes mellitus.

Necrotizing fasciitis of the perineum (Fournier’s gangrene)

. Post-registration cases of Fournier’s gangrene have been reported in patients taking SGLT2 inhibitors, including dapagliflozin (see See section “Special Indications”).

In the DECLARE study, a total of 6 cases of Fournier’s gangrene were reported in 17160 patients with DM2 and a median exposure of 48 months: one in the group receiving dapagliflozin and five in the placebo group.

Hypoglycemia

The incidence of hypoglycemia depended on the type of baseline therapy used in the DM2 clinical trials.

In studies of dapagliflozin as monotherapy, combination therapy with metformin lasting up to 102 weeks, the incidence of episodes of mild hypoglycemia was similar (< 5%) in treatment groups including placebo. In all studies, episodes of severe hypoglycemia were infrequent and their frequency was comparable between the dapagliflozin and placebo groups. In the studies of dapagliflozin as addition to sulfonylurea drug or insulin drug, a higher incidence of hypoglycemia was noted (see section “Interaction with other medicinal products”). In the study of dapagliflozin 10 mg, administered simultaneously with prolonged-acting exenatide (against the background of metformin use), no episodes of severe or mild hypoglycemia were noted.

The DECLARE study showed no increased risk of severe hypoglycemia with dapagliflozin therapy compared with placebo. Severe hypoglycemia was reported in 58 (0.7%) patients receiving dapagliflozin and 83 (1.0%) patients receiving placebo.

In the DAPA-HF study, severe hypoglycemia was reported in 4 (0.2%) patients in both the dapagliflozin and placebo groups and was seen only in patients with DM2.

In the DAPA-CKD study, severe hypoglycemia was reported in 14 (0.7%) patients in the dapagliflozin group and in 28 (1.3%) patients in the placebo group and was observed only in patients with DM2.

CPU reduction

. In pooled safety data from 13 studies, adverse reactions indicating decreased CPR (including reports of dehydration, hypovolemia, or arterial hypotension) were noted in 1.1% and 0.7% of patients taking dapagliflozin 10 mg and placebo, respectively; serious adverse reactions were noted in < 0.2% of patients, and they were comparable in the dapagliflozin 10 mg and placebo groups (see See section “Special Indications”).

In the DECLARE study, the number of patients with events indicative of decreased CPR was balanced between treatment groups: 213 (2.5%) and 207 (2.4%) in the dapagliflozin and placebo groups, respectively. Serious adverse events were reported in 81 (0.9%) and 70 (0.8%) patients in the dapagliflozin and placebo groups, respectively. The events were generally balanced between treatment groups in terms of age, diuretic use, blood pressure, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use. Among patients with a baseline rSFR < 60 mL/min/1.73 m², 19 cases of serious adverse events indicative of decreased RBC were noted in the dapagliflozin group and 13 in the placebo group.

In the DAPA-HF study, the number of patients with events indicative of decreased CPR was balanced between treatment groups: 170 (7.2%) and 153 (6.5%) in the dapagliflozin and placebo groups, respectively. The dapagliflozin group had fewer patients with serious phenomena in the form of symptoms indicative of decreased CPR compared with the placebo group: 23 (1.0%) and 38 (1.6%) patients, respectively. Similar results were observed in subgroup analyses by age, presence of diabetes mellitus at baseline, baseline rCF and BP.

In the DAPA-CKD study, the number of patients with phenomena suggestive of decreased ROC was 120 (5.6%) in the dapagliflozin group and 84 (3.9%) in the placebo group. In the dapagliflozin group, 16 (0.7%) patients had serious phenomena in the form of symptoms indicative of decreased OCC, and 15 (0.7%) patients in the placebo group.

Diabetic ketoacidosis in DM2

. In the DECLARE study with a median exposure of 48 months, diabetic ketoacidosis events were reported in 27 patients in the dapagliflozin 10 mg group and 12 patients in the placebo group. These phenomena occurred uniformly during the study period. In the dapagliflozin group, out of 27 patients with diabetic ketoacidosis

22 were receiving concomitant insulin therapy at the time the phenomenon developed. Predisposing factors for the development of diabetic ketoacidosis were expected in the DM2 population (see “Special Indications”).

In the DAPA-HF study, diabetic ketoacidosis events were reported in 3 patients with DM2 in the dapagliflozin group and none in the placebo group.

In the DAPA-CKD study, diabetic ketoacidosis was not reported in any patient in the dapagliflozin group, but was reported in 2 patients with DM2 in the placebo group.

Urinary tract infections

. In pooled safety data from 13 studies, urinary tract infections were more frequently reported with dapagliflozin 10 mg than with placebo (4.7% vs. 3.5%, respectively; see See section “Special Indications”). Most infections were mild to moderate; the initial course of standard therapy was effective, and patients rarely discontinued dapagliflozin. These infections were more frequent in women, and patients with a history of such infections were more likely to have recurrent infections.

In the DECLARE study, serious urinary tract infections were reported less frequently for dapagliflozin 10 mg compared with placebo: 79 (0.9%) events compared with 109 (1.3%) events, respectively.

In the DAPA-HF study, the number of patients with serious adverse events in the form of urinary tract infections was small and balanced: 14 (0.6%) patients in the dapagliflozin group and 17 (0.7%) patients in the placebo group. The dapagliflozin and placebo groups each had 5 (0.2%) patients with adverse events leading to discontinuation of treatment because of urinary tract infections.

In the DAPA-CKD trial, serious adverse events in the form of urinary tract infections were noted in 29 (1.3%) patients in the dapagliflozin group and in 18 (0.8%) patients in the placebo group. There were 8 (0.4%) patients in the dapagliflozin group with adverse events leading to discontinuation of treatment due to urinary tract infections and 3 (0.1%) patients in the placebo group. The number of patients who had serious adverse events or adverse events leading to discontinuation of treatment because of urinary tract infections was small and similar between treatment groups (6 [0.9%] compared with 4 [0.6%] for serious adverse events; 1 [0.1%] compared with 0 for adverse events leading to discontinuation of treatment) among patients without diabetes.

Elevated creatinine concentration

. The adverse reactions associated with increased creatinine concentrations were grouped (e.g., decreased renal clearance of creatinine, impaired renal function, increased blood creatinine concentration, and decreased GFR). In pooled safety data from 13 studies, this group of reactions was reported in 3.2% and 1.8% of patients receiving dapagliflozin 10 mg and placebo, respectively. In patients with normal or mild renal function impairment (baseline rCFR ≥60 mL/min/1.73 m²), this group of reactions was reported in 1.3% and 0.8% of patients receiving dapagliflozin 10 mg and placebo, respectively. These reactions were more common in patients with a baseline rSFR ≥30 and < 60 mL/min/1.73 m² (18.5% in the dapagliflozin 10 mg group compared with 9.3% in the placebo group).

Additional evaluation of patients with adverse events related to renal function showed that most of these patients showed a change in serum creatinine concentration of ≤0.5 mg/dL from baseline. The increase in creatinine concentration was generally temporary with continuation of therapy or reversible after discontinuation of therapy.

In the DECLARE study, which included elderly patients and patients with impaired renal function (rCF less than 60 mL/min/1.73 m²), rCF decreased over time in both treatment groups. After 1 year of therapy, the mean rSKF value was slightly lower in the dapagliflozin group and slightly higher after 4 years of therapy compared with the placebo group.

In the DAPA-HF study, there was a decrease in mean rSKF, which was initially more pronounced in the dapagliflozin group compared to the placebo group. After 20 months, the change in rGFR relative to baseline was similar between treatment groups.
