  Purpose
The goal of this clinical research study is to learn if BL-8040 in combination with cytarabine (Ara-C) can help to control the disease in patients with Acute Myeloid Leukemia (AML) that has relapsed or did not respond adequately to previous treatment. The safety of the study drug combination will also be studied.

Condition Intervention Phase

Primary Purpose: Treatment
Official Title: A PHASE IIA, MULTICENTER, OPEN-LABEL STUDY DESIGNED TO EVALUATE THE SAFETY AND EFFICACY OF ESCALATING DOSES OF BL-8040 IN ADULT SUBJECTS WITH RELAPSED/REFRACTORY ACUTE MYELOID LEUKEMIA

Primary Outcome Measures:
  • Safety and tolerability [ Time Frame: "participants will be followed for the duration of hospital stay and the follow up period, an expected average of 6 weeks. ]
    • General safety: Vital signs (oral temperature, blood pressure, pulse rate, respiratory rate and O2 saturation), 12-lead ECG and physical examination.
    • Toxicity according to the latest version of NCI-CTCAE (currently V4.03, refer to )
    • for AEs and clinical laboratory profile as follows: Screening: record and report screening results, however not considered treatment emergent AEs.

    Throughout the study: record and report all AEs and SAEs according to GCP.



Secondary Outcome Measures:
  • Clinical efficacy [ Time Frame: Final Bone Marrow evaluation -Between day 20 and day 44 ]
    The outcome will be measured by response rates as assessed at final Bone Marrow evaluation based on Cheson 2003 criteria.

  • Apoptotic effect [ Time Frame: Final evaluation- between day 20 and day 44 ]
    Change in leukemic cell apoptosis in Peripheral Blood and Bone Marrow.

  • Mobilization [ Time Frame: Final evaluation- between day 20 and day 44 ]
    Mobilization of AML blasts from the bone marrow to the peripheral blood (PB) by cell counting

  • Pharmacokinetic profile [ Time Frame: Day 0 to day 7 ]
    • Cmax - maximum BL-8040 plasma concentration
    • Tmax - time to reach the maximum BL-8040 plasma concentration
    • AUC0-t - Area under the BL-8040 plasma concentration-time curve AUC0-∞ - Area under the BL-8040 plasma concentration-time curve
    • λz - elimination rate constant, determined by linear regression t1/2 - terminal elimination half-life, defined as 0.693/λz


Other Outcome Measures:
  • Pharmacodynamic parameters [ Time Frame: After end of study- an expected average of 6 weeks. ]
    To assess additional pharmacodynamic parameters relevant to CXCR4 inhibition by CXCR4 receptor occupancy

Study Completion Date: June 2016
Primary Completion Date: March 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BL-8040 + Ara-C
Eligible subjects will receive subcutaneous (SC) injections of BL-8040 ("monotherapy period") over two days (one injection per day) followed by concurrent administration of BL-8040 with standard salvage chemotherapy ("combined period") over 5 days. During the "combined period," BL-8040 will be administered 4 hours prior to chemotherapy. The chemotherapy will consist of cytarabine (Ara-C) 1.5 or 3 g/m2/d per dose (based on age), administered intravenously (IV) over 3 hours, for 5 days and will not be escalated.
Drug: Ara-C
IV
Other Name: cytarabine
Drug: BL-8040
SC
Other Name: BL8040

Detailed Description:

Open-label, multicenter, phase IIa, dose escalating study in subjects with relapsed/refractory AML, defined according to WHO criteria (1), including subjects who failed chemotherapy only and those who failed previous Autologous Stem Cell Transplantation (ASCT) / Allogeneic Stem Cell Transplantation (AlloSCT), provided at least 6 months have passed from transplant.

Eligible subjects will receive subcutaneous (SC) injections of BL-8040 ("monotherapy period") over two days (one injection per day) followed by concurrent administration of BL-8040 with standard salvage chemotherapy ("combined period") over 5 days. During the "combined period," BL-8040 will be administered 4 hours prior to chemotherapy. The chemotherapy will consist of cytarabine (Ara-C) 1.5 or 3 g/m2/d per dose (based on age), administered intravenously (IV) over 3 hours, for 5 days and will not be escalated.

The first part of the study (Part 1) will include escalating dose groups and be considered the 'escalation phase'. Six potential dose levels (see Table 1) 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 and evaluated for dose escalation.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Adult men and women subjects aged 18 to 75, inclusive.
  2. Confirmed diagnosis of relapsed/refractory AML (WHO criteria) Refractory subjects, up to second consecutive salvage . Relapsed subjects including first and second relapse.
  3. AML relapse > 6 months since autologous or allogeneic stem cell transplantation, provided they are in first or second relapse and:

    No active graft-versus-host disease (GVHD > grade 1). No treatment with high dose steroids for GVHD (up to 20 mg Prednisolone or equivalent, Appendix G). No treatment with immunosuppressive drugs with the exception of low dose cyclosporine and tacrolimus (blood levels of 0.5-0.6 µg/mL).

  4. Clinical laboratory values should be as follows:

    WBC < 30,000/mL Blasts in PB ≤ 20,000. Treatment with Hydroxyurea is permitted up to 24 hrs prior to BL-8040 administration to achieve blast counts < 20,000 prior to enrollment.

    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.
