Clinical Trial of BP1001 (L-Grb-2 Antisense Oligonucleotide) in CML, AML, ALL & MDS

Acute Lymphoblastic Leukemia Clinical Trial

Official title: A Phase I Clinical Trial to Study the Safety, Pharmacokinetics, and Efficacy of BP1001 (L-Grb-2 Antisense Oligonucleotide) in Patients With Refractory or Relapsed Acute Myeloid Leukemia, Philadelphia Chromosome Positive Chronic Myelogenous Leukemia, or Acute Lymphoblastic Leukemia, and Myelodysplastic Syndrome

Status Completed

Clinical Trial Summary

The first goal of this clinical research study is to find the highest safe dose of BP1001, a liposomal Growth Factor Receptor Bound Protein-2 antisense oligodeoxynucleotide (L-Grb2 AS), for patients with Philadelphia Chromosome positive CML, AML, ALL and MDS. The response of the leukemia to this treatment will also be studied. The second goal of this clinical research study is to evaluate the safety and toxicity of the combination of BP1001 and concurrent low-dose ara-C (LDAC) in patients with AML.

Clinical Trial Description

The Philadelphia Chromosome is an unusual genetic trait found in 90-95% of patients with CML and approximately 20-25% of patients with ALL. The protein created by this unusual trait causes normal cells within the body to become cancer cells, and then causes these cells to grow and divide at a rapid rate. Researchers think that the protein "Growth Factor Receptor Bound Protein-2 (Grb-2)" plays an important role in the rapid growth of leukemic cells. The study drug (BP1001) may be able to inhibit the cells from making Grb-2. Researchers hope that without this protein, the leukemia cells will die.

Up to 60 patients are expected to be enrolled on this study.

Part A: Dose escalation: Each cohort will receive BP1001 at a dose higher than the previous group.

Part B: Dose-expansion Cohorts: Subjects with relapsed or refractory AML will receive escalating doses of BP1001 concurrently with fixed low-dose ara-C (LDAC)

The study drug is an antisense molecule complementary to the messenger RNA (mRNA) code for the cell's expression of the protein Grb-2. The study drug is incorporated into lipid (fat) particles known as liposomes. This incorporation process is part of the manufacturing process and is done before the study drug is administered. The liposomes (which carry the study drug) will be administered intravenously twice a week for 28 days. Subjects enrolled in Part B of the study will receive study drug twice a week for 28 days concurrently with low dose ara-C, self administered twice daily for 10 consecutive days. ;
