Baqsimi

BAQSIMI is supplied as an intranasal device containing one 3 mg dose of glucagon as a preservative free, white powder. BAQSIMI One Pack ® carton contains 1 intranasal device (NDC 0548-8351-01) BAQSIMI Two Pack ® carton contains 2 intranasal devices (NDC 0548-8352-02) Store at temperatures up to 86°F (30°C) in the shrink wrapped tube provided. Keep BAQSIMI in the shrink wrapped tube until ready to use. If the tube has been opened, BAQSIMI may have been exposed to moisture and may not work as expected. Discard BAQSIMI and tube after use.

BAQSIMI is for intranasal use only. ( 2.1 ) The recommended dose of BAQSIMI is 3 mg administered as one actuation of the intranasal device into one nostril. ( 2.2 ) Administer BAQSIMI according to the printed instructions on the shrink-wrapped tube label and the Instructions for Use. ( 2.1 ) Administer the dose by inserting the tip into one nostril and pressing the device plunger all the way in until the green line is no longer showing. The dose does not need to be inhaled. ( 2.1 ) Call for emergency assistance immediately after administering the dose. ( 2.1 ) When the patient responds to treatment, give oral carbohydrates. ( 2.1 ) Do not attempt to reuse BAQSIMI. Each BAQSIMI device contains one dose of glucagon and cannot be reused. ( 2.1 ) If there has been no response after 15 minutes, an additional 3 mg dose may be administered while waiting for emergency assistance. ( 2.2 ) 2.1 Important Administration Instructions BAQSIMI is for intranasal use only. Instruct patients and their caregivers on the signs and symptoms of severe hypoglycemia. Because severe hypoglycemia requires help of others to recover, instruct the patient to inform those around them about BAQSIMI and its Instructions for Use. Administer BAQSIMI as soon as possible when severe hypoglycemia is recognized. Instruct the patient or caregiver to read the Instructions for Use at the time they receive a prescription for BAQSIMI. Emphasize the following instructions to the patient or caregiver: Do not push the plunger or test the device prior to administration. Administer BAQSIMI according to the printed instructions on the shrink-wrapped tube label and the Instructions for Use. Administer the dose by inserting the tip into one nostril and pressing the device plunger all the way in until the green line is no longer showing. The dose does not need to be inhaled. Call for emergency assistance immediately after administering the dose. When the patient responds to treatment, give oral carbohydrates to restore the liver glycogen and prevent recurrence of hypoglycemia. Do not attempt to reuse BAQSIMI. Each BAQSIMI device contains one dose of glucagon and cannot be reused. 2.2 Dosage in Adults and Pediatric Patients Aged 4 Years and Above The recommended dose of BAQSIMI is 3 mg administered as one actuation of the intranasal device into one nostril. If there has been no response after 15 minutes, an additional 3 mg dose of BAQSIMI from a new device may be administered while waiting for emergency assistance.

BAQSIMI is contraindicated in patients with: Pheochromocytoma because of the risk of substantial increase in blood pressure [see Warnings and Precautions ( 5.1 )] Insulinoma because of the risk of hypoglycemia [see Warnings and Precautions ( 5.2 )] Known hypersensitivity to glucagon or to any of the excipients in BAQSIMI. Allergic reactions have been reported with glucagon and include anaphylactic shock with breathing difficulties and hypotension [see Warnings and Precautions ( 5.3 )] Pheochromocytoma ( 4 ) Insulinoma ( 4 ) Known hypersensitivity to glucagon or to any of the excipients ( 4 )

Substantial Increase in Blood Pressure in Patients with Pheochromocytoma : Contraindicated in patients with pheochromocytoma because BAQSIMI may stimulate the release of catecholamines from the tumor. ( 5.1 ) Hypoglycemia in Patients with Insulinoma : In patients with insulinoma, administration may produce an initial increase in blood glucose; however, BAQSIMI may stimulate exaggerated insulin release from an insulinoma and cause hypoglycemia. If a patient develops symptoms of hypoglycemia after a dose of BAQSIMI, give glucose orally or intravenously. ( 5.2 ) Serious Hypersensitivity Reactions : Serious hypersensitivity reactions have been reported and include generalized rash, and in some cases anaphylactic shock with breathing difficulties, and hypotension. ( 5.3 ) Lack of Efficacy in Patients with Decreased Hepatic Glycogen : BAQSIMI is effective in treating hypoglycemia only if sufficient hepatic glycogen is present. Patients in states of starvation, with adrenal insufficiency or chronic hypoglycemia may not have adequate levels of hepatic glycogen for BAQSIMI to be effective. Patients with these conditions should be treated with glucose. ( 5.4 ) 5.1 Substantial Increase in Blood Pressure in Patients with Pheochromocytoma BAQSIMI is contraindicated in patients with pheochromocytoma because glucagon may stimulate release of catecholamines from the tumor [see Contraindications ( 4 )]. If the patient develops a substantial increase in blood pressure and a previously undiagnosed pheochromocytoma is suspected, 5 to 10 mg of phentolamine mesylate, administered intravenously, has been shown to be effective in lowering blood pressure. 5.2 Hypoglycemia in Patients with Insulinoma In patients with insulinoma, administration of glucagon may produce an initial increase in blood glucose; however, BAQSIMI administration may directly or indirectly (through an initial rise in blood glucose) stimulate exaggerated insulin release from an insulinoma and cause hypoglycemia. BAQSIMI is contraindicated in patients with insulinoma [see Contraindications ( 4 )]. If a patient develops symptoms of hypoglycemia after a dose of BAQSIMI, give glucose orally or intravenously. 5.3 Serious Hypersensitivity Reactions Serious hypersensitivity reactions have been reported with glucagon products, including generalized rash, and in some cases anaphylactic shock with breathing difficulties and hypotension. Discontinue BAQSIMI if symptoms of serious hypersensitivity reactions occur. Advise patients and/or caregivers to seek immediate medical attention if the patient experiences any symptoms of serious hypersensitivity reactions. BAQSIMI is contraindicated in patients with a prior hypersensitivity reaction [see Contraindications ( 4 )]. 5.4 Lack of Efficacy in Patients with Decreased Hepatic Glycogen Patients with insufficient hepatic stores of glycogen may not respond to BAQSIMI for the treatment of severe hypoglycemia [see Clinical Pharmacology ( 12.2 )]. Insufficient hepatic stores of glycogen may be present in conditions such as states of starvation or in patients with adrenal insufficiency or chronic hypoglycemia.

Advise the patient and family members or caregivers to read the FDA-approved patient labeling ( Patient Information and Instructions for Use ). Recognition of Severe Hypoglycemia: Inform patient and family members or caregivers on how to recognize the signs and symptoms of severe hypoglycemia and the risks of prolonged hypoglycemia. Administration: Review the Patient Information and Instructions for Use with the patient and family members or caregivers. Serious Hypersensitivity: Inform patients that allergic reactions can occur with BAQSIMI. Advise patients to seek immediate medical attention if they experience any symptoms of serious hypersensitivity reactions [see Warnings and Precautions ( 5.3 )] .

Beta-blockers : Patients taking beta-blockers may have a transient increase in pulse and blood pressure. ( 7.1 ) Indomethacin : In patients taking indomethacin BAQSIMI may lose its ability to raise glucose or may produce hypoglycemia. ( 7.2 ) Warfarin : BAQSIMI may increase the anticoagulant effect of warfarin. ( 7.3 ) 7.1 Beta-blockers Patients taking beta-blockers may have a transient increase in pulse and blood pressure when given BAQSIMI. 7.2 Indomethacin In patients taking indomethacin, BAQSIMI may lose its ability to raise blood glucose or may even produce hypoglycemia. 7.3 Warfarin BAQSIMI may increase the anticoagulant effect of warfarin.

Long term studies in animals to evaluate carcinogenic potential have not been performed. Recombinant glucagon was positive in the bacterial Ames assay. It was determined that an increase in colony counts was related to technical difficulties in running this assay with peptides. Studies in rats have shown that glucagon does not cause impaired fertility.

Risk Summary Available data from case reports and a small number of observational studies with glucagon use in pregnant women over decades of use have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Multiple small studies have demonstrated a lack of transfer of pancreatic glucagon across the human placental barrier during early gestation. In a rat reproduction study, no embryofetal toxicity was observed with glucagon administered by injection during the period of organogenesis at doses representing up to 40 times the human dose, based on body surface area (mg/m 2 ) (see Data). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data In pregnant rats given animal sourced glucagon twice-daily by injection at doses up to 2 mg/kg (up to 40 times the human dose based on body surface area extrapolation, mg/m 2 ) during the period of organogenesis, there was no evidence of increased malformations or embryofetal lethality.

The safety and effectiveness of BAQSIMI for the treatment of severe hypoglycemia in patients with diabetes have been established in pediatric patients ages 4 years and above. Use of BAQSIMI for this indication is supported by evidence from a study in 48 pediatric patients from 4 to <17 years of age with type 1 diabetes mellitus. [see Clinical Studies ( 14.2 )] . The safety and effectiveness of BAQSIMI have not been established in pediatric patients younger than 4 years of age.

Clinical studies of BAQSIMI did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Limited clinical trial experience has not identified differences in responses between the elderly and younger patients.

The following serious adverse reactions are described below and elsewhere in labeling: Hypersensitivity and Allergic Reactions [see Warnings and Precautions ( 5.3 )] . Most common (≥10%) adverse reactions associated with BAQSIMI are nausea, vomiting, headache, upper respiratory tract irritation (i.e., rhinorrhea, nasal discomfort, nasal congestion, cough, and epistaxis), watery eyes, redness of eyes, itchy nose, throat and eyes. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Amphastar Pharmaceuticals Inc. at 1-800-423-4136 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial Data Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of BAQSIMI cannot be directly compared with rates in clinical trials of other drugs and may not reflect the rates observed in practice. Adverse Reactions in Adult Patients Two similarly designed comparator-controlled trials, Study 1 and Study 2, evaluated the safety of a single dose of BAQSIMI compared to a 1 mg dose of intra-muscular glucagon (IMG) in adult patients with diabetes [see Clinical Studies ( 14 )]. Table 1 presents adverse reactions that occurred with BAQSIMI at an incidence of ≥2% in a pool of Study 1 and Study 2. Table 1: Pooled Adverse Reactions (≥2%) in Adult Patients with Type 1 and Type 2 Diabetes in Study 1 and Study 2 a Upper Respiratory Tract Irritation: rhinorrhea, nasal discomfort, nasal congestion, cough, and epistaxis. Adverse Reaction BAQSIMI 3 mg (N=153) % Nausea 26.1 Headache 18.3 Vomiting 15.0 Upper Respiratory Tract Irritation a 12.4 Nasal and ocular symptoms with BAQSIMI were solicited through a patient questionnaire in Study 1 and 2 and these adverse reactions are presented in Table 2 . Table 2: Solicited Nasal and Non-Nasal Adverse Reactions in Adult Patients with Type 1 and Type 2 Diabetes Pooled from Study 1 and 2 a Subjects were asked to report whether they have the symptom, as well as severity (mild, moderate, severe) at baseline, and after glucagon administration. Adverse Reaction a BAQSIMI 3 mg (n=153) % Any increase in symptom severity a Watery eyes 58.8 Nasal congestion 42.5 Nasal itching 39.2 Runny nose 34.6 Redness of eyes 24.8 Itchy eyes 21.6 Sneezing 19.6 Itching of throat 12.4 Itching of ears 3.3 Adverse Reactions in Pediatric Patients Aged 4 Years and Above A single dose of BAQSIMI was compared to weight-based doses of 0.5 mg or 1 mg of IMG in pediatric patients with type 1 diabetes in Study 3 [see Clinical Studies ( 14 )]. Table 3 presents adverse reactions that occurred with BAQSIMI in pediatric patients at an incidence of ≥2% in Study 3. Table 3: Adverse Reactions (≥2%) Occurring in Pediatric Patients with Type 1 Diabetes in Study 3 a Upper Respiratory Tract Irritation: nasal discomfort, nasal congestion, sneezing. Adverse Reaction BAQSIMI 3 mg (n=36) % Vomiting 30.6 Headache 25.0 Nausea 16.7 Upper Respiratory Tract Irritation a 16.7 Nasal and ocular symptoms with BAQSIMI were solicited through a patient questionnaire in pediatric patients in Study 3 and these adverse reactions are presented in Table 4 . Table 4: Solicited Nasal and Non-Nasal Adverse Reactions in Pediatric Patients with Type 1 Diabetes in Study 3 a Subjects were asked to report whether they have the symptom, as well as severity (mild, moderate, severe) at baseline, and after glucagon administration. Adverse Reaction a BAQSIMI 3 mg (n=36) % Any increase in symptom severity a Watery eyes 47.2 Nasal congestion 41.7 Nasal itching 27.8 Runny nose 25.0 Sneezing 19.4 Itchy eyes 16.7 Redness of eyes 13.9 Itching of throat 2.8 Itching of ears 2.8 Other Adverse Reactions in Adult and Pediatric Patients Other observed adverse reactions with BAQSIMI-treated patients across clinical trials were, dysgeusia, pruritus, tachycardia, hypertension, and additional upper respiratory tract irritation events (nasal pruritus, throat irritation, and parosmia). 6.2 Immunogenicity As with all therapeutic peptides, there is the potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of incidence of antibodies to BAQSIMI with the incidences of antibodies to other products may be misleading. In 3 clinical trials, 3/124 (2%) of BAQSIMI-treated patients had treatment-emergent anti-drug antibodies as detected by an affinity capture elution (ACE) ligand-binding immunogenicity assay. No neutralizing antibodies were detected.

If overdosage occurs, the patient may experience nausea, vomiting, inhibition of GI tract motility, increase in blood pressure and pulse rate. In case of suspected overdosing, serum potassium levels may decrease and should be monitored and corrected if needed. If the patient develops a dramatic increase in blood pressure, phentolamine mesylate has been shown to be effective in lowering blood pressure for the short time that control would be needed.
