Safety and Dose Study of GRN163L Administered to Treat Patients With Refractory or Relapsed Multiple Myeloma
Safety and Dose Study of GRN163L Administered to Treat Patients With Refractory or Relapsed Multiple Myeloma
The purpose of this study is to determine the safety and the maximum tolerated dose (MTD) of
 GRN163L when administered to patients with refractory or relapsed multiple myeloma.
GRN163L is a telomerase template antagonist with in vitro and in vivo activity in a variety
 of tumor model systems. Telomerase is an enzyme that is active primarily in tumor cells and
 is crucial for the indefinite growth of tumor cells. Inhibition of telomerase may result in
 antineoplastic effects.
Inclusion Criteria:

 -  Confirmed diagnosis of multiple myeloma (either secretory or nonsecretory disease)

 -  Relapsed or refractory disease

 -  At least two prior treatment regimens

 -  ECOG performance status 0-2

 -  Adequate hepatic/renal function and platelet count

 -  If previously treated with an anthracycline, anthracenedione, or trastuzumab, must
 have left ventricular ejection fraction > 50%

 Exclusion Criteria:

 -  Prior allogeneic bone marrow transplant, including syngeneic transplant

 -  Known intracranial disease or epidural disease

 -  Prior malignancy (within the last 3 years)

 -  Clinically relevant active infection

 -  Serious co-morbid medical conditions, including cirrhosis and chronic obstructive or
 chronic restrictive pulmonary disease

 -  Symptomatic hyperviscosity syndrome

 -  Any other cancer therapy within 3 weeks prior to study, except for mitomycin C,
 nitrosoureas, or high-dose chemotherapy with stem cell support within 6 weeks prior to
 study

 -  Investigational therapy within 4 weeks prior to study

 prophylaxis therapy and low dose heparin administration for management of IV access
 devices
