Last Updated: February 7, 2013
Status: Discontinued

Products Affected - Description

Elspar, Lundbeck
10,000 units, 10 mL vial (NDC 67386-0411-51) - discontinued

Reason for the Shortage

  • Lundbeck discontinued the sale of Elspar in December 2012.1,2
  • Lundbeck states the decision to discontinue Elspar was a business decision.2
  • Lundbeck recommends that remaining product be allocated for human use and current patients finish treatment protocols with Elspar. Patients should consult with their healthcare provider to discuss if alternative treatment may be appropriate.2
  • Asparaginase Erwinia Chrysanthemi (Erwinaze) and pegaspargase (Oncaspar) are not affected by this shortage.
  • Recordati acquired several products including Elspar from Lundbeck in late 2012. However, the company made a business decision in early 2013 to discontinue Elspar and not pursue further manufacturing.3

Estimated Resupply Dates

Lundbeck discontinued Elspar in late-December 2012.1,2

Implications for Patient Care

  • Elspar is an asparagine specific enzyme with labeled use as part of a multi-agent chemotherapy regimen in patients with acute lymphoblastic leukemia (ALL).4
  • Potential alternatives agents include pegaspargase (Oncaspar) or asparaginase Erwinia chrysanthemi (Erwinaze). Labeled uses for these medications include:
    • a) Pegaspargase is an asparagine specific enzyme labeled as part of a multi-agent chemotherapy regimen in patients with first-line ALL, or ALL and hypersensitivity to asparaginase. This product is L-asparaginase covalently conjugated to monomethoxypolyethylene glycol (mPEG). L-asparaginase is produced endogenously by E. coli.5
    • b) Asparaginase Erwinia chrysanthemi is an asparagine specific enzyme labeled as part of a multi-agent chemotherapeutic regimen in patients with ALL who have developed hypersensitivity to E. coli derived asparaginase.6

Safety

  • Chemotherapy agents, such as asparaginase, pose additional safety risks both for patients and for healthcare workers handling these agents.7,8
  • Use additional caution when processing orders for chemotherapy drugs, especially when switching between chemotherapy agents or when processing orders for chemotherapy agents with which staff may be unfamiliar (eg, those not normally prescribed at a specific institution).7,8

Alternative Agents & Management

  • The choice of an alternative agent must be patient-specific and based on renal function, liver function, and the neoplasm type and location. No single agent can be substituted for asparaginase.7-9
  • Consult a Hematology/Oncology specialist for patient- and neoplasm-specific recommendations.
  • Refer to the ASHP Guidelines on Managing Drug Product Shortages for more guidance on developing a multidisciplinary plan when the supply must be allocated.
