| dailymed-drugs:2311 | dailymed-instance:dosage | Before prescribing ADAGEN (pegademase bovine) Injection the physician should be thoroughly familiar with the details of this prescribing information. For further information concerning the essential monitoring of ADAGEN (pegademase bovine) Injection therapy, the prescribing physician should contact ENZON Pharmaceuticals, Inc., 685 Route 202/206, Bridgewater, NJ 08807. Telephone 866-792-5172. ADAGEN (pegademase bovine) Injection is recommended for use in infants from birth or in children of any age at the time of diagnosis. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permits. ADAGEN (pegademase bovine) Injection should not be diluted nor mixed with any other drug prior to administration. ADAGEN (pegademase bovine) Injection should be administered every 7 days as an intramuscular injection. The dosage of ADAGEN (pegademase bovine) Injection should be individualized. The recommended dosing schedule is 10 U/kg for the first dose, 15 U/kg for the second dose, and 20 U/kg for the third dose. The usual maintenance dose is 20 U/kg per week. Further increases of 5 U/kg/week may be necessary, but a maximum single dose of 30 U/kg should not be exceeded. Plasma levels of ADA more than twice the upper limit of 35��mol/hr/mL have occurred on occasion in several patients, and have been maintained for several weeks in one patient who received twice weekly injections (20 U/kg per dose) of ADAGEN (pegademase bovine) Injection. No adverse effects have been observed at these higher levels; there is no evidence that maintaining pre-injection plasma ADA above 35��mol/hr/mL produces any additional clinical benefits. Dose proportionality has not been established and patients should be closely monitored when the dosage is increased. ADAGEN (pegademase bovine) Injection is not recommended for intravenous administration. The optimal dosage and schedule of administration should be established for each patient based on monitoring of plasma ADA activity levels (trough levels before maintenance injection) and biochemical markers of ADA deficiency (primarily red cell dATP content). Since improvement in immune function follows correction of metabolic abnormalities, maintenance dosage in individual patients should be aimed at achieving the following biochemical goals: 1) maintain plasma ADA activity (trough levels beforemaintenance injection) in the range of 15-35��mol/hr/mL (assayed at 37��C); and 2) decline in erythrocyte dATP to���0.005-0.015��mol/mL packed erythrocytes, or���1% of the total erythrocyte adenine nucleotide (ATP + dATP) content, with a normal ATP level, as measured in a pre-injection sample. In addition, continued monitoring of immune function and clinical status is essential in any patient with a primary immunodeficiency disease and should be continued in patients undergoing treatment with ADAGEN (pegademase bovine) Injection. | lld:dailymed |

| dailymed-drugs:2311 | dailymed-instance:precautio... | General: Any laboratory or clinical indication of a decrease in potency of ADAGEN (pegademase bovine) Injection should be reported immediately by telephone to Enzon Pharmaceuticals, Inc. Telephone 866-792-5172. There have been no reports of hypersensitivity reactions in patients who have been treated with ADAGEN (pegademase bovine) Injection. One of 12 patients showed an enhanced rate of clearance of plasma ADA activity after 5 months of therapy at 15 U/kg/week. Enhanced clearance was correlated with the appearance of an antibody that directly inhibited both unmodified ADA and ADAGEN (pegademase bovine) Injection. Subsequently, the patient was treated with twice weekly intramuscular injections at an increased dose of 20 U/kg, or a total weekly dose of 40 U/kg. No adverse effects were observed at the higher dose and effective levels of plasma ADA were restored. After 4 months, the patient returned to a weekly dosage schedule of 20 U/kg and effective plasma levels have been maintained. Appropriate care to protect immune deficient patients should be maintained until improvement in immune function has been documented. The degree of immune function improvement may vary from patient to patient and, therefore, each patient will require appropriate care consistent with immunologic status.<br/>Laboratory Tests: The treatment of SCID associated with ADA deficiency with ADAGEN (pegademase bovine) Injection should be monitored by measuring plasma ADA activity and red blood cell dATP levels. Plasma ADA activity and red cell dATP should be determined prior to treatment. Once treatment with ADAGEN (pegademase bovine) Injection has been initiated, a desirable range of plasma ADA activity (trough level before maintenance injection) should be 15���35��mol/hr/mL. This minimum trough level will ensure that plasma ADA activity from injection to injection is maintained above the level of total erythrocyte ADA activity in the blood of normal individuals. Plasma ADA activity (pre-injection) should be determined every 1-2 weeks during the first 8-12 weeks of treatment in order to establish an effective dose of ADAGEN (pegademase bovine) Injection. After 2 months of maintenance treatment with ADAGEN (pegademase bovine) Injection, red cell dATP levels should decrease to a range of���0.005 to 0.015��mol/mL. The normal value of dATP is below 0.001��mol/mL. Once the level of dATP has fallen adequately, it should be measured 2-4 times a year during the remainder of the first year and 2-3 times a year thereafter, assuming no interruption in therapy. Between 3 and 9 months, plasma ADA should be determined twice a month, then monthly until after 18-24 months of treatment with ADAGEN (pegademase bovine) Injection. Patients who have successfully been maintained on therapy for two years should continue to have plasma ADA measured every 2-4 months and red cell dATP measured twice yearly. More frequent monitoring would be necessary if therapy were interrupted or if an enhanced rate of clearance of plasma ADA activity develops. Once effective ADA plasma levels have been established, should a patient's plasma ADA activity level fall below 10��mol/hr/mL (which cannot be attributed to improper dosing, sample handling or antibody development) then all patients receiving this lot of ADAGEN (pegademase bovine) Injection will be required to have a blood sample for plasma ADA determination taken prior to their next injection of ADAGEN (pegademase bovine) Injection. The index patient will require re-testing for determination of plasma ADA activity prior to his/her next injection of ADAGEN (pegademase bovine)Injection. If this value, as well as the value from one of the other patients from a different site, is less than 10��mol/hr/mL then the lot in use will be recalled and replaced with a new clinical lot by ENZON Pharmaceuticals, Inc. Immune function, including the ability to produce antibodies, generally improves after 2-6 months of therapy, and matures over a longer period. Compared with the natural history of combined immunodeficiency disease due to ADA deficiency, a trend toward diminished frequency of opportunistic infections and fewer complications of infections has occurred in patients receiving ADAGEN (pegademase bovine) Injection. However, the lag between the correction of the metabolic abnormalities and improved immune function with a trend toward diminished frequency of infections and complications of infection is variable, and has ranged from a few weeks to approximately 6 months. Improvement in the general clinical status of the patient may be gradual (as evidenced by improvement in various clinical parameters) but should be apparent by the end of the first year of therapy. Antibody to ADAGEN (pegademase bovine) Injection may develop in patients and may result in more rapid clearance of ADAGEN (pegademase bovine) Injection. Antibody to ADAGEN (pegademase bovine) Injection should be suspected if a persistent fall in pre-injection levels of plasma ADA to<10��mol/hr/mL occurs. If other causes for a decline in plasma ADA levels can be ruled out [such as improper storage of ADAGEN (pegademase bovine) Injection vials (freezing or prolonged storage at temperatures above 8��C), or improper handling of plasma samples (e.g., repeated freezing and thawing during transport to laboratory)], then a specific assay for antibody to ADA and ADAGEN (pegademase bovine) Injection (ELISA, enzyme inhibition) should be performed. In patients undergoing treatment with ADAGEN (pegademase bovine) Injection, a decline in immune function, with increased risk of opportunistic infections and complications of infection, will result from failure to maintain adequate levels of plasma ADA activity [whether due to the development of antibody to ADAGEN (pegademase bovine) Injection, to improper calculation of ADAGEN (pegademase bovine) Injection dosage, to interruption of treatment or to improper storage of ADAGEN (pegademase bovine) Injection with subsequent loss of activity]. If a persistent decline in plasma ADA activity occurs, immune function and clinical status should be monitored closely and precautions should be taken to minimize the risk of infection. If antibody to ADA or ADAGEN (pegademase bovine) Injection is found to be the cause of a persistent fall in plasma ADA activity, then adjustment in the dosage of ADAGEN (pegademase bovine) Injection and other measures may be taken to induce tolerance and restore adequate ADA activity.<br/>Drug Interactions: There are no known drug interactions with ADAGEN (pegademase bovine) Injection. However, Vidarabine is a substrate for ADA and 2���-deoxycoformycin is a potent inhibitor of ADA. Thus, the activities of these drugs and ADAGEN (pegademase bovine) Injection could be substantially altered if they are used in combination with one another.<br/>Carcinogenesis, Mutagenesis, Impairment of Fertility: Long-term carcinogenic studies in animals have not been performed with ADAGEN (pegademase bovine) Injection nor have studies been performed on impairment of fertility. ADAGEN (pegademase bovine) Injection did not exhibit a mutagenic effect when tested against Salmonella typhimurium strains in the Ames assay.<br/>Pregnancy: Pregnancy Category C. Animal reproduction studies have not been conducted with ADAGEN (pegademase bovine) Injection. It is also not known whether ADAGEN (pegademase bovine) Injection can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. ADAGEN (pegademase bovine) Injection should be given to a pregnant woman only if clearly needed.<br/>Nursing Mothers: It is not known whether ADAGEN (pegademase bovine) Injection is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when ADAGEN (pegademase bovine) Injection is administered to a nursing woman. | lld:dailymed |
