Arms Assigned Interventions
0 mg/kg Drug: Intravenous Recombinant Human Mannose-Binding Lectin (rhMBL)
Intravenous (i.v.) administration for 4 weeks. Patients will be randomized to one of three cohorts: 0 mg/kg; 0.5 mg/kg, or 1.0
0.5 mg/kg Drug: Intravenous Recombinant Human Mannose-Binding Lectin (rhMBL)
Intravenous (i.v.) administration for 4 weeks. Patients will be randomized to one of three cohorts: 0 mg/kg; 0.5 mg/kg, or 1.0
1.0 mg/kg Drug: Intravenous Recombinant Human Mannose-Binding Lectin (rhMBL)
Intravenous (i.v.) administration for 4 weeks. Patients will be randomized to one of three cohorts: 0 mg/kg; 0.5 mg/kg, or 1.0

Detailed Description:
MBL deficient patients will be randomized in a ratio of 2:2:1 to receive up to 4 weekly i.v. infusions of rhMBL at a dose of 0.5 mg/kg or 1.0 mg/kg, or standard anti-infectious prophylactic therapy alone. A total of 20 patients will be treated in each of the rhMBL arms, and 10 patients will receive best standard supportive prophylactic therapy but not rhMBL. All patients are to receive anti-infectious prophylactic supportive therapy as per institutional standards.

  • Age ≥18 years old.
  • Score of 0 to 2 on the Zubrod performance status scale.
  • Patient is scheduled to receive melphalan-based high-dose chemotherapy and autologous HSCT for the treatment of multiple myeloma.

Exclusion Criteria:
