Imatinib and BL-8040 (Novel Anti CXCR4 Antagonist) for Improving Molecular Response in Chronic Myelogenous Leukemia
Chronic Myeloid Leukemia
About this trial
This is an interventional treatment trial for Chronic Myeloid Leukemia focused on measuring Chronic myeloid leukemia, imatinib, CXCR4 antagonist, BL-8040
Eligibility Criteria
Inclusion Criteria:
- Adult men and women subjects aged 18 to 70, inclusive.
- Confirmed diagnosis of chronic phase CML according to the WHO criteria (WHO 2008)
CML patients with sub-optimal response to Tyrosine Kinase Inhibitors, defined as "warning" in the ELN recommendations:
Following 3 months: BCR-ABL1 > 10%, and/or Ph+ 36-95% Following 6 months: BCR-ABL1 1-10%, and/or Ph + 1-35% Following 12 months: BCR-ABL1 0.1-1 % Following 24 months: Less than MR4
Clinical laboratory values should be as follows:
White blood cell count < 30 X 10*9/L Creatinine < 1.5 ULN
- Women of childbearing potential and all men must agree to use approved form of contraception
- Subject is able and willing to comply with the requirements of the protocol.
- Subject is able to voluntarily provide written informed consent.
Exclusion Criteria:
- CML patients not in chronic phase.
- CML patients receiving Tyrosine Kinase Inhibitors other than Imatinib.
- CML patients receiving Imatinib > 400 mg/day.
- Patients not able to sign informed consent.
- Known allergy or hypersensitivity to any of the test compounds or materials or contraindication to test product.
- Low Performance Status (ECOG > 2).
Abnormal liver function tests:
- Serum aspartate transaminase (AST/SGOT) or alanine transaminase (ALT/SGPT) 2 x upper limit of normal (ULN).
- Serum bilirubin. Total bilirubin > 2.0 mg/dL (34 µmol/L), conjugated bilirubin > 0.8 mg/dL
- Abnormal left ventricular ejection fraction, < 40 %.
Subject has concurrent, uncontrolled medical condition, laboratory abnormality, or psychiatric illness which could place him/her at unacceptable risk, including, but not limited to:
- Subject has been diagnosed or treated for another malignancy within 3 years of enrolment, except in situ malignancy, or low-risk prostate, skin or cervix cancer after curative therapy
- A co-morbid condition which, in the view of the Investigators, renders the subject at high risk from treatment complications.
- Women subjects who are pregnant or breastfeeding.

Arms of the Study
Arm 1
Experimental
BL-8040
Patients with chronic phase CML on Imatinib therapy (400 mg/day) achieving less than an optimal response will be treated with sc injections of BL-8040, while continuing Imatinib. The first part of the study will include escalating dose groups. Up to 4 dose levels will be investigated starting at dose level 1. Patients will be accrued in a conventional 3+3 design. Applying this study design, the first cohort of 3 patients will be treated at dose level 1 (0.5 mg/kg) on Day 1, 15, 29 and 43. Patients will continue taking Imatinib 400 mg/day throughout the study. Dose escalation will continue until the maximal tolerated dose (MTD) is established and protocol specific stopping rules for toxicity are met. If no MTD is reached, dose escalation will continue up to dose level 4 (1.25 mg/kg).
