Brief Summary

The purpose of this study is to evaluate the safety and efficacy of NOX A12 in combination with a background therapy of bendamustine and rituximab (BR) chemotherapy in previously treated patients with chronic lymphocytic leukemia (CLL).

Detailed Description

CLL cells express high levels of CXCR4 chemokine receptors, which cause leukemia cell migration and adhesion to stromal cells secreting the CXCR4 ligand, CXCL12 (or stromal-derived-factor 1, SDF-1). NOX A12 is a specific CXCL12 antagonist and may improve BR therapy by disrupting CXCR4-CXCL12 interactions, thereby mobilizing CLL cells from protective tissue microenvironments to the blood. Furthermore, SDF-1 inhibition may alter the activation status of CLL cells, thereby triggering apoptosis or sensitization of CLL cells towards chemotherapy.

Conditions

Chronic Lymphocytic Leukemia

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

NOX-A12

Group Type: EXPERIMENTAL

NOX-A12

Intervention Type: DRUG

Pilot Group (NOX-A12 single agent, and combined with BR):

• 3 cohorts of 3 patients will receive treatment with NOX-A12 alone at a single dose of 1, 2 or 4 mg/kg i.v. 2 weeks before the combination treatment of NOX-A12 and BR begins.The combination of NOX-A12 and BR will follow a dose titration design beginning at 1 mg/kg NOX-A12 (cycle 1), proceeding to dose levels of 2 mg/kg (cycle 2) and 4 mg/kg (cycle 3) NOX-A12 in combination with BR. This is followed by consolidation in cycles 4-6 when NOX-A12 will be kept at the highest individually titrated dose.

Expansion Group (NOX-A12 in combination with BR):

• Expansion patients will not receive single agent NOX-A12, but will receive combination treatment as for the pilot group.

11. Male or female, age ≥ 18

12. No clinically significant abnormalities of liver volume, liver hemodynamics or elasticity, measured by abdominal ultrasound.

Exclusion Criteria

1. Relapse of B-cell CLL within 12 months after last chemotherapy.

2. Subjects who have progressed to more aggressive B-cell cancers such as Richter's syndrome.

3. CLL with documented loss of the short arm of chromosome 17 (17p-) associated with the loss of p53.

4. The subject has a history of or is clinically suspicious for cancer-related Central Nervous System disease.

5. Patients at risk of hemostasis or spleen rupture.

6. Autoimmune hemolytic anemia.

7. Prior allogeneic stem cell transplant (alloSCT) or patients who are considered to be candidates for allo SCT as assessed by their treating physician

8. Patient has a history of other active malignancies within three years prior to study entry, with the exception of: adequately treated in situ carcinoma of the cervix uteri; basal or squamous cell carcinoma of the skin; in situ carcinoma of the bladder; previous malignancy confined and surgically resected with curative intent.

9. The patient exhibits evidence of other clinically significant uncontrolled condition(s) including, but not limited to: uncontrolled systemic infection (viral, bacterial, or fungal); diagnosis of fever and neutropenia within 1 week prior to study drug administration.

10. Female subject is pregnant or breast-feeding.

11. Known infection with HIV, active Hepatitis B or Hepatitis C.

12. The patient has a history of prior toxicity from bendamustine or rituximab that resulted in permanent discontinuation of treatments.

13. Treatment with other investigational drugs, or participation in another clinical trial within 30 days prior to study drug administration.

15. Myocardial infarction or unstable angina within the past 6 months prior to study drug administration.

16. Systemic illnesses or other severe concurrent disease including alcoholism which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and efficacy of the investigational treatments.

17. Known or suspected of not being able to comply with the trial protocol.

18. Having been previously enrolled in this clinical trial.

19. Known hypersensitivity to rituximab or to any of the excipients or to murine proteins

20. History of recurring or chronic infections or underlying conditions which may further predispose patients to serious infection.

21. Known hypersensitivity to bendamustine or to mannitol.

22. Invasive surgery within 30 days prior to study drug administration.
