Safety and Efficacy of Obatoclax Mesylate (GX15-070MS) for the Treatment of Hematological Malignancies
Defects in the apoptotic process can lead to the onset of cancer by allowing cells to grow unchecked when an oncogneic signal is present. Obatoclax is designed to restore apoptosis through inhibition of the Bcl-2 family of proteins, thereby reinstating the natural process of cell death that is often inhibited in cancer cells.

|Study Design:||Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase I Study of Obatoclax Mesylate (GX15-070MS) in Patients With Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS), Chronic Myeloid Leukemia (CML)in Myeloid Blast Phase, Myelofibrosis, Previously-Treated Chronic Lymphocytic Leukemia (CLL), or Aplastic Anemia|
- Determine the recommended Phase II dose of GX15-070MS; Characterize the DLTs of GX15-070MS; Determine the PK/PD response to GX15-070MS
- Describe any clinical responses of patient with hematological malignancies.
|Study Start Date:||October 2005|
|Primary Completion Date:||October 2007 (Final data collection date for primary outcome measure)|
This is a multi-center, open-label, Phase I study of obatoclax administered every 2-week or weekly cycles, or as a Prolonged Infusion every 2 to 3 weeks to patients with Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS), Chronic Myeloid Leukemia (CML)in Myeloid Blast Phase, Myelofibrosis, Previously-Treated Chronic Lymphocytic Leukemia (CLL), or Aplastic Anemia. Due to the PK/PD sampling schedule Cycle 1 will require overnight hospitalization. For the following cycles treatment may be administered on an outpatient basis but is at the discretion of the investigator. No investigational or commercial agents or therapies other than those described within the protocol may be administered with the intent to treat the patient's malignancy. Supportive care measures including those directed at controlling symptoms resulting from hematological malignancies are allowed.
