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).
Chronic Lymphocytic Leukemia
||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||A Multi-center, Open Label, Uncontrolled, Phase IIA Clinical Trial Evaluating the Safety and Efficacy of NOX A12 in Combination With a Background Therapy of Bendamustine and Rituximab (BR) in Previously Treated Patients With Chronic Lymphocytic Leukemia (CLL)
Primary Outcome Measures:
Secondary Outcome Measures:
- Pharmacodynamics of NOX-A12 alone and in combination with BR [ Time Frame: 6 months ]
The pharmacodynamics evaluation will be based on the following assessments:
- mobilization of peripheral blood CD34+ cells and CLL cells
- plasma concentration of SDF-1/CXCL12
- Overall response rate (ORR = CR + PR) [ Time Frame: 6 months ]
- Progression free survival (PFS) [ Time Frame: 30 months ]
- Pharmacokinetics of NOX-A12 alone and in combination with BR [ Time Frame: 10 time points over 6 months ]
The pharmacokinetics evaluation will be based on the following assessments:
- plasma concentration of NOX-A12
- 24-hour urine excretion of NOX-A12
- Event free survival (EFS) [ Time Frame: 30 months ]
- Time to progression (TTP) [ Time Frame: 30 months ]
- Duration of response (DOR) [ Time Frame: 30 months ]
- Overall survival (OS) [ Time Frame: 30 months ]

| Primary Completion Date:
||November 2014 (Final data collection date for primary outcome measure)
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.

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.

- Pre-study WHO performance status ≤ 2 and modified cumulative illness rating score (CIRS) of less than 7.
- Signed, written informed consent.
- Men and women of reproductive potential must agree to follow accepted birth control methods during treatment and for 3 months after completion of treatment.
- Acceptable liver function: Bilirubin ≤ 1.5 x upper limit of normal (ULN) at screening, AST (SGOT) and/or ALT (SGPT) ≤ 2.5 x ULN.
- Acceptable hematologic status: Platelet count ≥ 75 x 109/L, ANC > 0.75x109/L.
- Acceptable renal function: Serum creatinine ≤1.5 ULN and/or calculated creatinine clearance (Cockroft-Gault Formula) ≥ 50 mL/min
- Male or female, age ≥ 18
- No clinically significant abnormalities of liver volume, liver hemodynamics or elasticity, measured by abdominal ultrasound.
- Relapse of B-cell CLL within 12 months after last chemotherapy.
- Subjects who have progressed to more aggressive B-cell cancers such as Richter's syndrome.
- CLL with documented loss of the short arm of chromosome 17 (17p-) associated with the loss of p53.
- The subject has a history of or is clinically suspicious for cancer-related Central Nervous System disease.
- Patients at risk of hemostasis or spleen rupture.
- Autoimmune hemolytic anemia.
- Prior allogeneic stem cell transplant (alloSCT) or patients who are considered to be candidates for allo SCT as assessed by their treating physician
- 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.
- 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.
- Female subject is pregnant or breast-feeding.
- Known infection with HIV, active Hepatitis B or Hepatitis C.
