FRAGMIN

FRAGMIN Injection (dalteparin sodium injection) is a sterile, low molecular weight heparin. It is available in single-dose, prefilled syringes preassembled with a needle guard device, and multiple-dose vials. With reference to the W.H.O. First International Low Molecular Weight Heparin Reference Standard, each syringe contains either 2,500 units, 5,000 units, 7,500 units, 10,000 units, 12,500 units, 15,000 units or 18,000 anti-Xa international units (units), equivalent to 16 mg, 32 mg, 48 mg, 64 mg, 80 mg, 96 mg or 115.2 mg dalteparin sodium, respectively. Each multiple-dose vial contains 25,000 anti-Xa units per 1 mL (equivalent to 160 mg dalteparin sodium), for a total of 95,000 anti-Xa units per vial. Each single-dose vial contains 2,500 anti-Xa units per 1 mL (equivalent to 16 mg dalteparin sodium) for a total of 10,000 anti-Xa units per vial. Each prefilled syringe also contains Water for Injection and sodium chloride, when required, to maintain physiologic ionic strength. The prefilled syringes are preservative-free. Each multiple-dose vial also contains Water for Injection and 14 mg of benzyl alcohol per mL as a preservative. The pH of both formulations is 5.0 to 7.5. When necessary, the pH of FRAGMIN is adjusted with hydrochloric acid and/or sodium hydroxide [see Dosage and Administration (2.7) and How Supplied/Storage and Handling (16) ] . Dalteparin sodium is produced through controlled nitrous acid depolymerization of sodium heparin from porcine intestinal mucosa followed by a chromatographic purification process. It is composed of strongly acidic sulfated polysaccharide chains (oligosaccharide, containing 2,5-anhydro-D-mannitol residues as end groups) with an average molecular weight of 5,000 and about 90% of the material within the range 2,000–9,000. The molecular weight distribution is: <3000 daltons 3.0–15% 3,000 to 8,000 daltons 65.0–78.0% >8,000 daltons 14.0–26.0% Structural Formula Chemical Structure

Table 5 Starting Doses for Pediatric Patients with Symptomatic VTE Age Group Starting Dose Birth (gestational age at least 35 weeks) to less than 2 Years 150 units/kg twice daily 2 Years to less than 8 Years 125 units/kg twice daily 8 Years to less than 17 Years 100 units/kg twice daily After initiation of FRAGMIN, measure anti-Xa level prior to the 4 th dose. Samples for anti-Xa level should be drawn 4 hours after administration of FRAGMIN. Adjust doses in increments of 25 units/kg to achieve target anti-Xa level between 0.5 units/mL and 1 unit/mL. Individualize the maintenance dose of FRAGMIN based on the dose that achieves target anti-Xa level collected 4 hours after administration of FRAGMIN . Monitor anti-Xa level periodically in pediatric patients to maintain anti-Xa level between 0.5 units/mL and 1 unit/mL [see Clinical Pharmacology (12.3) and Clinical Studies (14.5) ] . The 3.8 mL multiple-dose vials of FRAGMIN contain 14 mg/mL of benzyl alcohol [see Warnings and Precautions (5.3) ] . Whenever possible, administer benzyl alcohol-free formulations (prefilled syringes) in pediatric patients [see Warnings and Precautions (5.3) and Use in Specific Populations (8.4) ] . The 10,000 units/4 mL (2,500 units/mL) single-dose vials are preservative-free. For treatment of neonates, use this vial presentation. 2.5 Dose Reductions for Thrombocytopenia in Adult Patients with Cancer and in Pediatric Patients with Symptomatic VTE Dose reductions recommended in patients receiving FRAGMIN who experience thrombocytopenia are presented below in Table 6. Table 6 Platelet Count less than or equal to 50,000/mm 3 Platelet Count greater than 50,000/mm 3 up to 100,000/mm 3 Adults Discontinue FRAGMIN until platelet count recovers to above 50,000/mm 3 . Reduce the daily dose of FRAGMIN by 2,500 units until the platelet count recovers to greater or equal to 100,000/mm 3 . Children from birth (gestational age at least 35 weeks) to less than 17 Years Discontinue FRAGMIN until platelet count recovers to above 50,000/mm 3 . Reduce the daily dose of FRAGMIN by 50% until the platelet count recovers to greater or equal to 100,000/mm 3 . 2.6 Dose Reductions for Renal Insufficiency in Extended Treatment of Acute Symptomatic VTE in Adult Patients with Cancer In patients with severely impaired renal function (CrCl <30 mL/min), monitor anti-Xa levels to determine the appropriate FRAGMIN dose. Target anti-Xa range is 0.5 units/mL to 1.5 units/mL. When monitoring anti-Xa in these patients, perform sampling 4 hours to 6 hours after FRAGMIN dosing and only after the patient has received 3 to 4 doses [ see Clinical Pharmacology (12.3) ] . 2.7 Administration Latex Allergy: Persons with latex allergies should not handle the FRAGMIN prefilled syringe because the needle shield may contain natural rubber latex which may cause allergic reactions. FRAGMIN is administered by subcutaneous injection. It must not be administered by intramuscular injection. FRAGMIN Injection should not be mixed with other injections or infusions unless specific compatibility data are available that support such mixing. Subcutaneous injection technique: Patients should be sitting or lying down and FRAGMIN administered by deep subcutaneous injection. FRAGMIN may be injected in a U-shape area around the navel, the upper outer side of the thigh or the upper outer quadrangle of the buttock. The injection site should be varied daily. When the area around the navel or the thigh is used, using the thumb and forefinger, you must lift up a fold of skin while giving the injection. The entire length of the needle should be inserted at a 45 to 90 degree angle. Inspect FRAGMIN prefilled syringes and vials visually for particulate matter and discoloration prior to administration. After first penetration of the rubber stopper, store the multiple-dose vials at room temperature for up to 2 weeks. Discard any unused solution after 2 weeks. Instructions for using the prefilled single-dose syringes preassembled with needle guard devices Fixed dose syringes: To ensure delivery of the full dose, do not expel the air bubble from the prefilled syringe before injection. Hold the syringe assembly by the open sides of the device. Remove the needle shield. Insert the needle into the injection area as instructed above. Depress the plunger of the syringe while holding the finger flange until the entire dose has been given . The needle guard will not be activated unless the entire dose has been given. Remove needle from the patient. Let go of the plunger and allow syringe to move up inside the device until the entire needle is guarded. Discard the syringe assembly in approved containers. Graduated syringes: Hold the syringe assembly by the open sides of the device. Remove the needle shield. With the needle pointing up, prepare the syringe by expelling the air bubble and then continuing to push the plunger to the desired dose or volume, discarding the extra solution in an appropriate manner. Insert the needle into the injection area as instructed above. Depress the plunger of the syringe while holding the finger flange until the entire dose remaining in the syringe has been given . The needle guard will not be activated unless the entire dose has been given. Remove needle from the patient. Let go of the plunger and allow syringe to move up inside the device until the entire needle is guarded. Discard the syringe assembly in approved containers. Figure

Hemorrhage The most commonly reported adverse reactions are hematoma at the injection site and hemorrhagic complications. The risk for bleeding varies with the indication and may increase with higher doses. Unstable Angina and Non-Q-Wave Myocardial Infarction Table 7 summarizes major bleeding reactions that occurred with FRAGMIN, heparin, and placebo in clinical trials of unstable angina and non-Q-wave myocardial infarction.

Adult Patients with Cancer and Acute Symptomatic VTE Table 11 summarizes the number of patients with bleeding reactions that occurred in the clinical trial of adult patients with cancer and acute symptomatic VTE. A bleeding event was considered major if it: 1) was accompanied by a decrease in hemoglobin of ≥2 g/dL in connection with clinical symptoms; 2) occurred at a critical site (intraocular, spinal/epidural, intracranial, retroperitoneal, or pericardial bleeding); 3) required transfusion of ≥2 units of blood products; or 4) led to death. Minor bleeding was classified as clinically overt bleeding that did not meet criteria for major bleeding. At the end of the six-month study, a total of 46 (13.6%) patients in the FRAGMIN arm and 62 (18.5%) patients in the OAC arm experienced any bleeding event. One bleeding event (hemoptysis in a patient in the FRAGMIN arm at Day 71) was fatal. Table 11 Bleeding Reactions (Major and Any) (As treated population) Patients with multiple bleeding episodes within any time interval were counted only once in that interval. However, patients with multiple bleeding episodes that occurred at different time intervals were counted once in each interval in which the event occurred.

In the FRAGMIN clinical trial of patients with cancer and acute symptomatic venous thromboembolism treated with FRAGMIN for up to 6 months, asymptomatic increases in transaminase levels, AST and ALT, greater than three times the upper limit of normal of the laboratory reference range were reported in 8.9% and 9.5% of patients, respectively. The frequencies of Grades 3 and 4 increases in AST and ALT, as classified by the National Cancer Institute, Common Toxicity Criteria (NCI-CTC) Scoring System, were 3% and 3.8%, respectively. Grades 2, 3 & 4 combined have been reported in 12% and 14% of patients, respectively. Other Allergic Reactions: Allergic reactions (i.e., pruritus, rash, fever, injection site reaction, bullous eruption) have occurred. Cases of anaphylactoid reactions have been reported. Local Reactions: Pain at the injection site was reported in 4.5% of patients treated with FRAGMIN 5,000 units once daily vs 11.8% of patients treated with heparin 5,000 units twice daily in the abdominal surgery trials. In the hip replacement trials, pain at injection site was reported in 12% of patients treated with FRAGMIN 5,000 units once daily vs 13% of patients treated with heparin 5,000 units three times a day. Pediatric Patients with Symptomatic VTE The data below reflect exposure to FRAGMIN from two studies in pediatric patients from newborn to less than 18 years of age with or without cancer and symptomatic VTE (n = 50). Patients were started on FRAGMIN using age and weight-based dosing via subcutaneous injection twice daily. Anti-Xa levels were measured prior to the 4 th dose and then periodically to determine whether dose adjustments were required, using 25 units/kg increments, to achieve a target anti-Xa level of 0.5 units/mL to 1.0 units/mL. The median time on treatment with FRAGMIN was 86 days (range 2 days to 170 days). In pediatric patients with symptomatic VTE, the most common (greater than 10%) adverse reactions were injection site bruising (30%), contusion (12%), and epistaxis (10%). Major bleeding was defined as any fatal bleeding, clinically overt bleeding with a decrease in hemoglobin of ≥2g/dL in 24 hours, overt bleeding deemed by the attending physician to be unrelated to the subject's underlying condition and accompanied by blood product administration, overt bleeding that was retroperitoneal, intracranial, intraspinal, intraocular, or intraarticular, or overt bleeding deemed by the attending physician to necessitate permanent discontinuation of trial medication. Major bleeding (intestinal hematoma) occurred in one patient (2%). Discontinuation due to adverse reactions occurred in 12% of patients, most often due to thrombocytopenia (4%). Neonatal Patients No controlled clinical trials have been conducted with FRAGMIN in neonatal patients with VTE; however, data are available from a non‑interventional retrospective medical chart review study of 16 neonates with VTE in the UK who were admitted to hospital between January 2010 and December 2021 and were treated with FRAGMIN. The mean (±SD) duration of dalteparin treatment was 62±30 days. For these 16 neonatal patients, the mean (±SD) daily dose of dalteparin at initiation was 365±196 units/kg (median:309 units/kg). The mean (±SD) daily dose of dalteparin including dose at initiation and dose changes was 575±320 units/kg (median: 450 units/kg). After the initial dose, all patients required one or more dose changes; 15 of 16 patients required dose increases due to anti-Xa level being initially below the target range of 0.5 units/mL to 1 units/mL. The safety profile in neonates was similar to other pediatric patients. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of FRAGMIN. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Since first international market introduction in 1985, there have been more than 15 reports of epidural or spinal hematoma formation with concurrent use of FRAGMIN and spinal/epidural anesthesia or spinal puncture. The majority of patients had postoperative indwelling epidural catheters placed for analgesia or received additional drugs affecting hemostasis. In some cases, the hematoma resulted in long-term or permanent paralysis (partial or complete) [see Boxed Warning ] . Musculoskeletal system: Osteoporosis Skin or subcutaneous tissues disorders: Skin necrosis, cases of alopecia reported that improved on drug discontinuation Metabolism and nutrition disorders: Hyperkalemia

The use of FRAGMIN in patients receiving oral anticoagulants, platelet inhibitors, and thrombolytic agents may increase the risk of bleeding [see Warnings and Precautions (5) ] .
