Drug Detail:Cathflo activase (Alteplase [ al-te-plase ])
Drug Class: Thrombolytics
Cathflo Activase Description
Cathflo® Activase® (Alteplase) is a tissue plasminogen activator (t‑PA) produced by recombinant DNA technology. It is a sterile, purified glycoprotein of 527 amino acids. It is synthesized using the complementary DNA (cDNA) for natural human tissue‑type plasminogen activator (t‑PA) obtained from an established human cell line. The manufacturing process involves secretion of the enzyme Alteplase into the culture medium by an established mammalian cell line (Chinese hamster ovary cells) into which the cDNA for Alteplase has been genetically inserted.
Cathflo Activase (Alteplase) for injection is a sterile, white to pale yellow, lyophilized powder for intracatheter instillation for restoration of function to central venous access devices following reconstitution with Sterile Water for Injection, USP.
Each vial of Cathflo Activase contains 2.2 mg of Alteplase (which includes a 10% overfill), 77 mg of L‑arginine, 0.2 mg of polysorbate 80, and phosphoric acid for pH adjustment. Each reconstituted vial will deliver 2 mg of Cathflo Activase, at a pH of approximately 7.3.
Precautions
Bleeding
The most frequent adverse reaction associated with all thrombolytics in all approved indications is bleeding (3,4). Cathflo Activase has not been studied in patients known to be at risk for bleeding events that may be associated with the use of thrombolytics. Caution should be exercised with patients who have active internal bleeding or who have had any of the following within 48 hours: surgery, obstetrical delivery, percutaneous biopsy of viscera or deep tissues, or puncture of non‑compressible vessels. In addition, caution should be exercised with patients who have thrombocytopenia, other hemostatic defects (including those secondary to severe hepatic or renal disease), or any condition for which bleeding constitutes a significant hazard or would be particularly difficult to manage because of its location, or who are at high risk for embolic complications (e.g., venous thrombosis in the region of the catheter). Death and permanent disability have been reported in patients who have experienced stroke and other serious bleeding episodes when receiving pharmacologic doses of a thrombolytic.
Should serious bleeding in a critical location (e.g., intracranial, gastrointestinal, retroperitoneal, pericardial) occur, treatment with Cathflo Activase should be stopped and the drug should be withdrawn from the catheter.
Infections
Cathflo Activase should be used with caution in the presence of known or suspected infection in the catheter. Using Cathflo Activase in patients with infected catheters may release a localized infection into the systemic circulation (see ADVERSE REACTIONS). As with all catheterization procedures, care should be used to maintain aseptic technique.
Adverse Reactions/Side Effects
The following adverse reactions are discussed in greater detail in Section PRECAUTIONS of the label:
- Bleeding
- Hypersensitivity
In the clinical trials, the most serious adverse events reported after treatment were sepsis (see PRECAUTIONS, Infections), gastrointestinal bleeding, and venous thrombosis.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Cathflo Activase Dosage and Administration
Cathflo® Activase® (Alteplase) is for instillation into the dysfunctional catheter at a concentration of 1 mg/mL.
• Patients weighing ≥30 kg: | 2 mg in 2 mL |
• Patients weighing <30 kg: | 110% of the internal lumen volume of the catheter, not to exceed 2 mg in 2 mL |
If catheter function is not restored at 120 minutes after 1 dose of Cathflo Activase, a second dose may be instilled (see Instructions for Administration). There is no efficacy or safety information on dosing in excess of 2 mg per dose for this indication. Studies have not been performed with administration of total doses greater than 4 mg (two 2‑mg doses).
How is Cathflo Activase supplied
Cathflo Activase (Alteplase) for injection is supplied as a sterile, lyophilized powder in 2 mg vials.
Cathflo®Activase® is available in a carton that contains one 2 mg vial of Cathflo® Activase® (Alteplase): NDC 50242‑041‑64 or a carton that contains ten 2 mg vials of Cathflo® Activase® (Alteplase): NDC 50242-041-10.
