For Healthcare Professionals

Applies to insulin glargine / lixisenatide: subcutaneous solution.


The most commonly occurring adverse reactions with this combination drug include hypoglycemia, allergic reactions, nausea, nasopharyngitis, diarrhea, upper respiratory tract infection, and headache.[Ref]


The rates of hypoglycemia depend on the definition of hypoglycemia. For clinical trials with this drug, severe hypoglycemia was defined as an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. Symptomatic hypoglycemia was defined as an event with typical symptoms of hypoglycemia accompanied by a self-monitored plasma glucose value of 70 mg/dL or less. Incidence of severe symptomatic hypoglycemia in 2 trials (n=469 and n=365) was 0% and 1.1% while documented symptomatic hypoglycemia was 25.6% and 40%, respectively.[Ref]

Very common (10% or more): Hypoglycemia (up to 40%)[Ref]


GLP-1 receptor agonists

Postmarketing reports: Acute kidney injury[Ref]

Postmarketing reports of acute kidney injury and worsening renal failure, some requiring hemodialysis, have been received in patients treated with GLP-1 receptor agonists.[Ref]


Twenty-one cases of pancreatitis were reported during clinical trials with lixisenatide compared with 14 cases in comparator-treated patients. Cases included acute pancreatitis (n=3), pancreatitis (n=12), chronic pancreatitis (n=5), and edematous pancreatitis (n=1). Some patients had risk factors for pancreatitis, such as a history of cholelithiasis or alcohol abuse. GLP-1 receptor agonists have been associated with acute pancreatitis including fatal and non-fatal hemorrhagic or necrotizing pancreatitis.

Gastrointestinal events occur more frequently at the beginning of therapy.[Ref]


Very common (10% or more): Nausea (10%)

Common (1% to 10%): Diarrhea

Frequency not reported: Vomiting, constipation, dyspepsia, gastritis, abdominal pain, flatulence, gastroesophageal reflux disease, abdominal distension, decreased appetite


Frequency not reported: Pancreatitis[Ref]


In lixisenatide clinical trials, a higher incidence of allergic reactions occurred in antibody positive patients.[Ref]


Frequency not reported: Severe, life-threatening, generalized allergy including anaphylaxis; generalized skin reactions, angioedema, bronchospasm, hypotension, shock


Uncommon (0.1% to 1%): Anaphylaxis, allergic reactions

Frequency not reported: Angioedema[Ref]


Common (1% to 10%): Injection site reactions

Frequency not reported: Lipodystrophy, lipohypertrophy[Ref]

Injection site reactions occurred in 1.7% of patients during clinical trials. Injection site reactions included injection-site hematoma, pain, hemorrhage, erythema, nodules, swelling, discoloration, pruritus, warmth, and injection-site mass.[Ref]



Very common (10% or more): Antibody formation (up to 43%)


Common (1% to 10%): High antibody concentrations with attenuated glycemic response[Ref]

Following 30 weeks of treatment with insulin glargine-lixisenatide, the incidence of anti-insulin glargine antibodies and anti-lixisenatide antibodies was up to 26.2% and approximately 43%, respectively. In about 93% of patients, anti-insulin glargine antibodies showed cross-reactivity to human insulin.

In lixisenatide clinical trials, pooled analysis has shown that 70% of lixisenatide-treated patients were antibody positive at 24 weeks. A subset (2.4%) with the highest antibody concentration showed an attenuated glycemic response. A higher incidence of allergic reactions and injection-site reactions occurred in antibody positive patients.[Ref]


Insulin Glargine:

Frequency not reported: Peripheral edema[Ref]

Some patients have experienced edema while taking insulin glargine, especially if previously poor metabolic control was improved by intensified insulin therapy.[Ref]

Nervous system

Common (1% to 10%): Headache[Ref]
