[Posted 10/25/2011] ISSUE: FDA notified healthcare professionals and the public that on October 25, 2011, Eli Lilly and Company announced a worldwide voluntary market withdrawal of drotrecogin alfa (activated) [Xigris]. In a recently completed clinical trial (PROWESS-SHOCK trial), drotrecogin alfa (activated) failed to show a survival benefit for patients with severe sepsis and septic shock.
BACKGROUND: Drotrecogin alfa (activated) is indicated for the reduction of mortality in adult patients with severe sepsis who have a high risk of death.
RECOMMENDATION: For more information visit the FDA website at: and .
Introduction
Biosynthetic (recombinant DNA origin) form of human activated protein C with antithrombotic, anti-inflammatory, and profibrinolytic properties.1 2 5 6
Uses for Drotrecogin Alfa (Activated)
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
Severe Sepsis
Used for mortality reduction in adults with severe sepsis and a high risk of death (e.g., as determined by an Acute Physiology and Chronic Health Evaluation [APACHE II] score of ≥25).1 2 4 7 9 International guidelines for the management of severe sepsis and septic shock suggest use in patients who generally have multiple organ failure and an APACHE score of ≥25.21
Efficacy not established and use not recommended in patients with a lower risk of death (e.g., APACHE II score <25) or in pediatric patients.1 2 11 16 18 21 22
Accurate diagnosis of severe sepsis and assessment of risk of death are critical when considering patients for therapy.1 11
Drotrecogin Alfa (Activated) Dosage and Administration
General
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
Discontinue therapy 2 hours prior to an invasive surgical procedure or procedures with an inherent risk of bleeding.1 9 Once adequate hemostasis is achieved, reconsider reinitiating therapy at initial recommended doses 12 hours after major invasive procedures or surgery or immediately following uncomplicated, less invasive procedures.1
Immediately discontinue therapy in patients with clinically important bleeding.1
Administration
Administer by continuous IV infusion using a controlled infusion device (i.e., infusion pump or syringe pump).1 9
IV Administration
For solution and drug compatibility information, see Compatibility under Stability.
Do not admix or infuse concomitantly with other drugs.1 (See Compatibility under Stability.)
Reconstitution
Determine appropriate number of vials to reconstitute by calculating the amount of drug required for a particular infusion period based on patient's actual body weight (in kg) and duration of infusion (in hours); round total amount to nearest 5-mg increment to avoid wastage.1 A maximum infusion period of 12 hours is recommended for each infusion bag or syringe; multiple infusions are required to cover recommended 96-hour duration of therapy.1
Reconstitute vial containing 5 or 20 mg of drotrecogin alfa (activated) with 2.5 or 10 mL of sterile water for injection, respectively, to provide solutions containing 2 mg/mL.1
Swirl vial gently to ensure dissolution; do not invert or shake vial.1 Must be diluted further before IV administration.1
Reconstituted solutions contain no preservatives; solutions preferably should be diluted immediately after reconstitution.1 If not used immediately, solution may be stored at 20–25°C, but must be used within 3 hours.1
Dilution
Dilute reconstituted solution with 0.9% sodium chloride injection in an IV infusion bag or syringe compatible with a syringe pump according to the manufacturer's directions to yield a concentration of 100–200 mcg/mL.1
Administer at room temperature within 12 hours of dilution; if not used immediately, store at 2–8°C for up to 12 hours.1 Total in-use time, including dilution, refrigeration, and administration, should not exceed 24 hours.1 4 10
Rate of Administration
Administer by IV infusion at 24 mcg/kg per hour for a total of 96 hours.1 9 If infusion is interrupted for >1 hour, extend infusion time to account for interruptions (i.e., allow for a total infusion duration of 96 hours) unless the interruption lasts for ≥36 hours.4
When administering the drug at low flow rates (< approximately 5 mL/hr), prime syringe pump for approximately 15 minutes at a flow rate of approximately 5 mL/hour.1
Dosage
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
Dosage escalation or loading doses are not recommended.1
Dosage adjustment based on clinical or laboratory parameters is not recommended.1

Hematologic Effects
Serious bleeding events, including intracranial hemorrhage, have occurred in patients receiving drotrecogin alfa (activated) therapy.1 2 14 16 19 20 Possible increased risk of bleeding in patients with one or more of the following conditions: concurrent heparin therapy to treat an active thrombotic or embolic event; platelet counts <30,000/mm3 (even if the platelet count is increased after transfusions); PT-INR >3; recent (within 6 weeks) GI bleeding; recent (within 3 days) thrombolytic therapy; recent (within 7 days) administration of oral anticoagulants, platelet glycoprotein (GP IIb/IIIa) inhibitors or other platelet-aggregation inhibitors (e.g., > 650 mg of aspirin daily); recent (within 3 months) ischemic stroke (see Contraindications under Cautions); intracranial arteriovenous malformation or aneurysm; known bleeding diathesis; chronic severe hepatic disease; or any other condition in which bleeding constitutes a substantial hazard or would be particularly difficult to manage because of its location.1
In a retrospective study of patients who received drotrecogin alfa (activated) for sepsis, serious bleeding events and deaths occurred in substantially more patients with baseline bleeding risk factors than those without such risk factors.13 14 15 FDA is currently investigating these preliminary findings and is working with the manufacturer to further evaluate the risk of serious bleeding and mortality in patients receiving drotrecogin alfa (activated).13 Pending completion of the safety review, FDA states that clinicians should carefully weigh the anticipated benefits of drotrecogin alfa (activated) against the risk of bleeding in any patient being considered for therapy.1 13
Some clinicians suggest avoiding use in patients with baseline bleeding risk factors.14 15 If clinically important bleeding occurs, immediately discontinue therapy.1 22 Also evaluate continued use of other agents affecting the coagulation system.1 (See Specific Drugs under Interactions.) Manufacturer states that resumption of therapy may be considered once adequate hemostasis has been achieved;1 however, some clinicians recommend against reinitiation of therapy in patients who develop severe bleeding during the infusion.22 (See General under Dosage and Administration.)
Patients with Single-Organ Dysfunction and Recent Surgery
Higher mortality reported in placebo-controlled clinical studies within a small subset of patients receiving drotrecogin alfa (activated) therapy who had single-organ dysfunction and recent surgery (i.e., within 30 days prior to treatment).1 2 11 16 Some of these patients had a lower risk of death (e.g., APACHE II score <25 or sepsis-induced single-organ failure at any APACHE II score) than that of the indicated population for this drug.1 11 16 22
Patients with single-organ dysfunction and recent surgery may not be at high risk of death (regardless of APACHE II score); drotrocegin alfa (activated) therapy is not recommended in such patients.1 11 21 22
Concomitant Administration of Prophylactic Heparin
Higher rates of mortality demonstrated in patients receiving drotrecogin alfa (activated) who discontinue prophylactic enoxaparin or unfractionated heparin therapy.1 20 Consider continuing low molecular weight heparin for prophylaxis of venous thromboembolism in patients receiving drotrecogin alfa (activated) unless discontinuance is medically necessary.1 20
Laboratory Test Interferences
May interfere with one-stage coagulation assays (e.g., factor VIII, IX, XI assays) based on aPTT; minimal effect on PT.1
Invasive Procedures
Discontinue drug prior to any invasive procedure (e.g., surgery) associated with an inherent risk of bleeding.1 9 (See General under Dosage and Administration.)
Minimize invasive procedures, including arterial and venous punctures, during drotrecogin alfa (activated) therapy; avoid establishing IV access at noncompressible sites (e.g., subclavian or jugular veins).1 (See Hematologic Effects under Cautions.)
Laboratory Monitoring
Do not use aPTT to monitor degree of coagulopathy; may use PT instead.1
Sensitivity Reactions
Antibody Formation
Antibodies to drotrecogin alfa (activated) reported in 1.5% of patients in clinical trials; a few patients tested positive for neutralizing antibodies.1 No apparent correlation between presence of antibodies and adverse effects.1
Limited experience with readministration (i.e., >1 course of therapy) of drotrecogin alfa (activated) in patients with severe sepsis;1 no hypersensitivity reactions or evidence of antibody development reported.1 4
Specific Populations
Pregnancy
Category C.1
Lactation
Not known whether drotrecogin alfa (activated) is distributed into milk.1 Discontinue nursing or the drug, taking into account the importance of the drug to the mother.1
Pediatric Use
Safety and efficacy not demonstrated in children <18 years of age;1 18 not indicated for use in pediatric patients with severe sepsis.1 21 22
Interim analysis of a randomized, double-blind study evaluating safety and efficacy in pediatric patients with severe sepsis showed that treatment with drotrecogin alfa (activated) was highly unlikely to result in improvement in the primary end point (composite time to complete organ failure resolution over a 14-day period) compared with placebo; as a result, the study was discontinued before completion.1 18 In addition, the rate of CNS bleeding was numerically greater in the drotrecogin alfa (activated) group than in the placebo group.1 18 Of patients with intracranial hemorrhage, the majority were <60 days of age.18 The incidence of 28-day all-cause mortality, fatal CNS bleeding, serious adverse events, overall serious bleeding events, and major amputations appeared to be similar between the groups.1 18
Geriatric Use
No overall differences in safety and efficacy relative to younger adults.1
Common Adverse Effects
Bleeding (e.g., ecchymoses, GI bleeding, intracranial hemorrhage).1
