Indication, Limitations of Use, and Important Safety Information
Jentadueto® (linagliptin and metformin hydrochloride) tablets
INDICATION AND IMPORTANT LIMITATIONS OF USE
JENTADUETO tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus when treatment with both linagliptin and metformin is appropriate.
JENTADUETO should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis.
JENTADUETO has not been studied in patients with a history of pancreatitis.
IMPORTANT SAFETY INFORMATION
WARNING: RISK OF LACTIC ACIDOSIS
Lactic acidosis is a rare, but serious, complication that can occur due to metformin accumulation. The risk increases with conditions such as renal impairment, sepsis, dehydration, excess alcohol intake, hepatic impairment, and acute congestive heart failure.
The onset is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, increasing somnolence, and nonspecific abdominal distress.
Laboratory abnormalities include low pH, increased anion gap, and elevated blood lactate.
If acidosis is suspected, JENTADUETO should be discontinued and the patient hospitalized immediately.
JENTADUETO is contraindicated in patients with:
- Renal impairment (e.g., serum creatinine ≥1.5 mg/dL for men or ≥1.4 mg/dL for women, or abnormal creatinine clearance).
- Acute or chronic metabolic acidosis, including diabetic ketoacidosis.
- History of hypersensitivity reaction to linagliptin (such as urticaria, angioedema, or bronchial hyperreactivity) or metformin.
WARNINGS AND PRECAUTIONS
- Lactic acidosis is a serious metabolic complication that can occur due to metformin accumulation during treatment with JENTADUETO and is fatal in approximately 50% of cases.
- The reported incidence of lactic acidosis in patients receiving metformin is approximately 0.03 cases/1000 patient-years, with approximately 0.015 fatal cases/1000 patient-years. Reported cases have occurred primarily in diabetic patients with significant renal impairment, including both intrinsic renal disease and renal hypoperfusion, often in the setting of multiple concomitant medical/surgical problems and multiple concomitant medications.
- Patients with congestive heart failure requiring pharmacologic management, particularly when accompanied by hypoperfusion and hypoxemia due to unstable or acute failure, are at increased risk of lactic acidosis.
- The risk of lactic acidosis increases with the degree of renal impairment and the patient's age. The risk of lactic acidosis may be significantly decreased by regular monitoring of renal function in patients taking metformin. Treatment of the elderly should be accompanied by careful monitoring of renal function. Metformin treatment should not be initiated in any patients unless measurement of creatinine clearance demonstrates that renal function is not reduced.
- Metformin should be promptly withheld in the presence of any condition associated with hypoxemia, dehydration, or sepsis.
There have been postmarketing reports of acute pancreatitis, including fatal pancreatitis, in patients taking linagliptin. Take careful notice of potential signs and symptoms of pancreatitis. If pancreatitis is suspected, promptly discontinue JENTADUETO and initiate appropriate management. It is unknown whether patients with a history of pancreatitis are at increased risk for the development of pancreatitis while using JENTADUETO.
Monitoring of Renal Function
Before initiation of therapy with JENTADUETO and at least annually thereafter, renal function should be assessed and verified as normal. In patients in whom development of renal impairment is anticipated (e.g., elderly), renal function should be assessed more frequently and JENTADUETO discontinued if evidence of renal impairment is present.
Radiological studies and surgical procedures: JENTADUETO should be temporarily discontinued prior to any intravascular radiocontrast study and for any surgical procedure necessitating restricted intake of food or fluids, and withheld for 48 hours subsequent to the procedure and reinstituted only after renal function has been confirmed to be normal.
Impaired Hepatic Function
Impaired hepatic function has been associated with cases of lactic acidosis with metformin therapy. JENTADUETO tablets should generally be avoided in patients with clinical or laboratory evidence of hepatic impairment.
Use with Medications Known to Cause Hypoglycemia
Insulin secretagogues and insulin are known to cause hypoglycemia. The use of linagliptin in combination with an insulin secretagogue (e.g., sulfonylurea) was associated with a higher rate of hypoglycemia compared with placebo in a clinical trial. A lower dose of the insulin secretagogue or insulin may be required to reduce the risk of hypoglycemia when used in combination with JENTADUETO.
Vitamin B12 Levels
Vitamin B12 deficiency: Metformin may lower Vitamin B12 levels. Monitor hematologic parameters annually.
Alcohol is known to potentiate the effect of metformin on lactate metabolism. Patients should be warned against excessive alcohol intake while receiving JENTADUETO.
Cardiovascular collapse (shock) from whatever cause (e.g., acute congestive heart failure, acute myocardial infarction, and other conditions characterized by hypoxemia) has been associated with lactic acidosis and may also cause prerenal azotemia. When such events occur in patients on JENTADUETO therapy, the drug should be promptly discontinued.
There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with JENTADUETO or any other antidiabetic drug.
- In a 24-week factorial design study, adverse reactions reported in ≥5% of patients treated with JENTADUETO and more commonly than in patients treated with placebo were nasopharyngitis and diarrhea.
- In a 24-week factorial design study, hypoglycemia was reported in 4 (1.4%) of 286 subjects treated with linagliptin + metformin, 6 (2.1%) of 291 subjects treated with metformin and 1 (1.4%) of 72 subjects treated with placebo. In the placebo-controlled studies, hypoglycemia was more commonly reported in patients treated with the combination of linagliptin and metformin with SU (22.9%) compared with those treated with the combination of placebo and metformin with SU (14.8%).
- In the clinical trial program, pancreatitis was reported in 15.2 cases per 10,000 patient-years exposure while being treated with linagliptin compared with 3.7 cases per 10,000 patient-years exposure while being treated with comparator (placebo and active comparator, sulfonylurea). Three additional cases of pancreatitis were reported following the last administered dose of linagliptin.
- Because cationic drugs eliminated by renal tubular secretion theoretically have the potential for interaction with metformin by competing for common renal tubular transport systems, careful patient monitoring and dose adjustment of JENTADUETO and/or the interfering drug is recommended in patients who are taking cationic medications that are excreted via the proximal renal tubular secretory system.
- The efficacy of JENTADUETO may be reduced when administered in combination with a strong P-glycoprotein inducer or CYP3A4 inducer (e.g., rifampin). Use of alternative treatments is strongly recommended.
- The concomitant use of carbonic anhydrase inhibitors (e.g., topiramate) and metformin may induce metabolic acidosis. Use these drugs with caution in patients treated with JENTADUETO, as the risk of lactic acidosis may increase.
USE IN SPECIFIC POPULATIONS
- As there are no adequate and well-controlled studies in pregnant women, the safety of JENTADUETO in pregnant women is not known. JENTADUETO should be used during pregnancy only if clearly needed.
- It is not known whether linagliptin is excreted in human milk. Metformin is excreted in human milk in low concentrations. Because the potential for hypoglycemia in nursing infants may exist, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
- The safety and effectiveness of JENTADUETO in patients below the age of 18 have not been established.
- JENTADUETO should be used with caution as age increases, as aging can be associated with reduced renal function.
