Pharmacokinetic Study of Propylene Glycol-Free Melphalan HCl for Myeloablative Conditioning in Multiple Myeloma Patients Undergoing Autologous Transplantation

Inclusion Criteria

• Patients with symptomatic multiple myeloma (MM) requiring treatment at or following diagnosis.
• Patients with MM, who qualify for ASCT therapy, and have received pretransplant therapy prior to transplantation.
• Adult patients (≥18 years of age) meeting local institutional criteria to receive a total Melphalan dose of 200 mg/m^2 as a conditioning regimen.
• Patients with an adequate autologous graft, which is defined as an unmanipulated, cryopreserved, peripheral blood cell graft containing at least 2 × 106 CD34+ cells/kg, based on patient weight.
• Patients with adequate organ function, as measured by:
• Cardiac: Left ventricular ejection fraction at rest >40% (documented within 30 days prior to Day -3).
• Hepatic: Bilirubin 40 mL/min (measured or calculated/estimated).
• Pulmonary: Adjusted Diffusing capacity of the lungs for carbon monoxide (DLCO), forced expiratory volume in one second (FEV1), forced vital capacity (FVC) >50% of predicted value (corrected for hemoglobin level [Hgb]) and documented within prior to day -3.

Exclusion Criteria

• Patients with systemic AL amyloidosis (immunoglobulin light chain amyloidosis).
• Eastern Cooperative Oncology Group (ECOG) performance status ≥2.
• Patients with uncontrolled hypertension.
• Patients with a serious active bacterial, viral or fungal infection.
• Patients with prior malignancies except resected basal cell carcinoma or treated cervical carcinoma in situ. Cancer treated with curative intent >5 years previously will be allowed. Cancer treated with curative intent <5 years previously will not be allowed unless approved by the medical monitor.
• Female patients who are pregnant (positive human chorionic gonadotropin [ß-HCG]) or breastfeeding.
• Female patients of childbearing potential, who are unwilling to use adequate contraceptive techniques during and for one month following study treatment with Melphalan HCl for injection (propylene glycol free).
• Patients seropositive for HIV.
• Patients who are unwilling to provide informed consent.
• Patients receiving other concurrent anticancer therapy (including chemotherapy, radiation, hormonal treatment, or immunotherapy, but excluding corticosteroids) within 30 days prior to the ASCT or planning to receive any of these treatments prior to study discharge.
• Patients concurrently participating in any other clinical study.
• Patients who are hypersensitive or intolerant to any component of the study drug formulation.
