Clinical Trial Summary

This is a Phase II, open label, single arm, multi-centre study investigating the safety and efficacy of ofatumumab plus bendamustine in subjects with untreated or relapsed CLL.

Each subject from the screening phase who is willing to participate in the study and is found eligible according to the inclusion and exclusion criteria will enter the treatment phase and will receive a maximum of 6 Cycles of study treatment (ofatumumab plus bendamustine). All subjects will receive 3 Cycles of study treatment (Cycles 1, 2 and 3). Eligibility to receive study treatment for Cycles 4, 5 and 6 will be assessed following the 3rd Cycle. Subjects who have achieved at least stable disease with acceptable toxicity following 3 Cycles of treatment will be eligible to continue to receive study treatments for a maximum of 3 further Cycles. In case of progressive disease, at, or at any time after the start of Cycle 4, subjects must discontinue further study treatment and move into the study's follow-up period.

During the treatment phase, all eligible subjects will be allocated to receive the following study treatments:

1. Subjects with Untreated CLL: Up to 6 monthly intravenous infusions of ofatumumab (Cycle 1: 300 mg Day 1 and 1000 mg Day 8; subsequent Cycles: 1000 mg at Day 1 every 28 Days) in combination with up to 6 Cycles of intravenously infused bendamustine (90 mg/m2, Days 1 and 2, every 28 Days).

2. Subjects with Relapsed CLL: Up to 6 monthly intravenous infusions of ofatumumab (Cycle 1: 300 mg Day 1 and 1000 mg Day 8; subsequent Cycles: 1000 mg at Day 1 every 28 Days) in combination with up to 6 Cycles of intravenously infused bendamustine (70 mg/m2, Days 1 and 2, every 28 Days).

The studies primary endpoint is overall response rate (ORR) as determined by Investigator evaluation. The ORR is the percentage of subjects achieving an objective response (i.e., partial response or better), using the IWCLL updated NCI-WG guidelines. Response assessments are planned at the following time-points: After 3 Cycles of ofatumumab plus bendamustine treatment, after 6 Cycles of ofatumumab plus bendamustine treatment and after the last dose, if not after 6 cycles, of ofatumumab plus bendamustine treatment.

Follow-up assessments will be performed every 3 months following the last study treatment. The follow-up period will last for a maximum of 3 years. Response evaluation assessments to determine subject response or progression will be performed during the follow-up period, according to the IWCLL updated NCI-WG guidelines. Following progression, only survival status and details concerning the subject's next CLL therapy will be recorded.


Description:

This is a Phase II, open label, single arm, multi-centre study investigating the safety and efficacy of ofatumumab plus bendamustine in subjects with untreated or relapsed CLL.

The primary objective of this study is to evaluate the investigator assessed overall response rate (ORR), using the International Workshop for Chronic Lymphocytic Leukaemia (IWCLL) updated National Cancer Institute-sponsored Working Group (NCIWG) guidelines, in two populations i.e., subjects with previously untreated CLL and subjects with relapsed CLL administered ofatumumab plus bendamustine.

Secondary objectives are to evaluate the overall response rate with computed tomography scan (CT scan) assessment, complete response rate with and without CT scan assessment, progression free survival, overall survival, duration of response, safety and tolerability, disease, prognostic and biological marker correlation with clinical response in the two populations i.e., subjects with previously untreated CLL and subjects with relapsed CLL administered ofatumumab plus bendamustine.

Exploratory objectives are to investigate the relationship between genetic variants in host DNA and the efficacy, safety and/or tolerability of ofatumumab.

Each subject from the screening phase who is willing to participate in the study and is found eligible according to the inclusion and exclusion criteria will enter the treatment phase and will receive a maximum of 6 Cycles of study treatment (ofatumumab plus bendamustine). All subjects will receive 3 Cycles of study treatment (Cycles 1, 2 and 3). Eligibility to receive study treatment for Cycles 4, 5 and 6 will be assessed following the 3rd Cycle. Subjects who have achieved at least stable disease with acceptable toxicity following 3 Cycles of treatment will be eligible to continue to receive study treatments for a maximum of 3 further Cycles. In case of progressive disease, at, or at any time after the start of Cycle 4, subjects must discontinue further study treatment and move into the study's follow-up period.

During the treatment phase, all eligible subjects will be allocated to receive the following study treatments:

1. Subjects with Untreated CLL: Up to 6 monthly intravenous infusions of ofatumumab (Cycle 1: 300 mg Day 1 and 1000 mg Day 8; subsequent Cycles: 1000 mg at Day 1 every 28 Days) in combination with up to 6 Cycles of intravenously infused bendamustine (90 mg/m2, Days 1 and 2, every 28 Days).

2. Subjects with Relapsed CLL: Up to 6 monthly intravenous infusions of ofatumumab (Cycle 1: 300 mg Day 1 and 1000 mg Day 8; subsequent Cycles: 1000 mg at Day 1 every 28 Days) in combination with up to 6 Cycles of intravenously infused bendamustine (70 mg/m2, Days 1 and 2, every 28 Days).

Prior to each treatment Cycle, subjects must have an absolute neutrophil count > 1.0 x 109/L, a platelet count > 75 x 109/L, and must have recovered to Grade 1 or baseline from all clinically significant non-hematologic toxicities, other than nausea, vomiting or alopecia. If these retreatment criteria are not met, a treatment delay of up to 28 Days is permitted; thereafter, study treatment with bendamustine and ofatumumab must be discontinued. In cases of delays up to 14 Days, bendamustine treatment should be continued at the same dosage, but in case of a delay between 15-28 Days, the dosage of bendamustine must be reduced to 60 mg/m2 for all subsequent treatment Cycles for subjects recruited to the study with previously untreated CLL and 50 mg/m2 for all subsequent treatment Cycles for subjects recruited to the study with relapsed CLL.

Additionally, if within any Cycle, a subject develops a clinically significant Grade 3/4 non-hematologic toxicity, other than nausea, vomiting or alopecia, an absolute neutrophil count < 1.0 x 109/L, or a platelet count < 50% of the pre-treatment value, the bendamustine dose will also be reduced as stated above for all subsequent treatment Cycles.

Blood samples, lymph node examination, spleen and liver measurements, and constitutional symptom evaluations are performed monthly throughout the treatment phase. A bone marrow examination is required to confirm complete response (CR) at least two months after the final study treatment and when a subject fulfils the IWCLL updated NCI-WG requirements for CR. CT-Scans will also be performed, at least two months after the final study treatment, for subjects achieving a CR or partial response (PR) according to the IWCLL updated NCI-WG requirements. Follow-up assessments will be performed every 3 months following the last study treatment. The follow-up period will last for a maximum of 3 years. Response evaluation assessments to determine subject response or progression will be performed during the follow-up period, according to the IWCLL updated NCI-WG guidelines [Hallek, 2008]. Following progression, only survival status and details concerning the subject's next CLL therapy will be recorded.

Intervention

Biological:
Ofatumumab
Ofatumumab (ARZERRA™) is an immunoglobulin G1? (IgG1?) human monoclonal antibody that specifically recognises a distinct epitope encompassing both large and small extracellular loops on the human CD20 molecule expressed on B cells and binds to this site with high affinity with a dissociation half-life of approximately 3 hours. Ofatumumab induces more efficient complement-dependent cytotoxicity (CDC) mediated cell lysis in vitro, compared to rituximab, especially in low CD20 density cells.
Drug:
Bendamustine
Bendamustine is a cytostatic drug which structurally combines a purine-like benzamidazol nucleus and a bifunctional alkylating nitrogen mustard group.

Secondary Number of Participants With Confirmed Positive Response for Human Anti-human Antibodies (HAHA) at the Indicated Time Points The presence of HAHA in human serum was determined using a validated electrochemiluminescent assay in a multi-tier assay format. All samples were first assessed in a screening (SCR) assay, and the potential positive (Pos) samples were further tested in the confirmation (CNF) assays. Confirmed positives were reported as HAHA positive and titer was determined for each positive sample. The drug tolerance of the HAHA assay is 200 microgram/milliliter (µg/mL); thus, samples that tested negative in the assay and had ofatumumab concentrations no more than 200 µg/mL were considered as conclusive negative (C Neg) results. Cycle 1 Day 1 (C1D1), Cycle 6 Day 1 (C6D1), 6-Month Follow-up (F/U), and any post-dose time point No
Secondary Mean Maximum Decrease in Sum of the Product of the Diameter (SPD) From Baseline in Participants With Lymphadenopathy at Baseline Lymph nodes were evaluated by physical examination which involved recording the diameter in two planes (sum of the product of the diameter [SPD]) of the largest palpable node in each of the following sites: cervical, axillary, supraclavicular, inguinal and femoral. Lymphadenopathy is defined as lymph nodes with the largest diameter greater than 1.5 centimeters. The maximum reduction in SPD from Baseline at C2D1, C3D1, C4D1, C5D1, C6D1, 3-Month F/U, 6-Month F/U and 9-Month F/U are provided. Baseline, Cycle 2 Day 1 (C2D1), Cycle 3 Day 1 (C3D1), Cycle 4 Day 1 (C4D1), Cycle 5 Day 1 (C5D1), Cycle 6 Day 1 (C6D1), 3-Month Follow-Up (F/U), 6-Month F/U and 9-Month F/U No
Secondary Number of Participants With the Indicated Reduction in Organomegaly (Spleen and Liver) Organomegaly is the abnormal enlargement of organs. Physical examination of the liver (L) and spleen (S) were done at Scr, C1D1, C2D1, C3D1, C4D1, C5D1, C6D1, 3-Month F/U, 6-Month F/U and 9-Month F/U. The result of the physical examination of the liver (L) and spleen (S) was presented as normal (NOR), enlarged (EL) and not assessed (NOA). Screening (Scr), Cycle 2 Day 1 (C2D1), Cycle 3 Day 1 (C3D1), Cycle 4 Day 1 (C4D1), Cycle 5 Day 1 (C5D1), Cycle 6 Day 1 (C6D1), 3-Month Follow-Up (F/U), 6-Month F/U and 9-Month F/U No
Secondary Number of Participants With the Indicated Cytogenetics Testing at Baseline Who Also Had a Clinical Response After Last Dose of Study Treatment Cytogenetics refers to the study of numerical and structural chromosomal abnormalities. Cytogenetics (analyzed by fluorescent in situ hybridization [FISH]) of 17p deletion, 11q deletion, 17p or 11q deletions, 6q- or +12q or 13q- deletions, and no aberration at Baseline were summarized by clinical responses after the last dose of study treatment. Clinical responses included complete remission (CR), nodular partial remission (nPR), complete response with incomplete bone marrow Recovery (CRi), partial remission (PR), disease progression (PD), and stable disease (SD). The participants with a PR, CRi, PR or nPR are called responders and the participants with SD and PD are called non-responders. From the start of study treatment until earliest date of disease progression or death (up to up to 3 months following last dose of study treatment) No
Secondary Number of Participants With the Indicated Beta 2 Microglobulin (B2M) at Baseline Who Also Had a Clinical Response After the Last Dose of Study Treatment Participants with B2M concentration of <=4000 µg/L and >4000 µg/L at Baseline and who had clinical response after the last dose of study treatment were provided. Clinical responses included complete remission (CR), complete response with incomplete bone marrow Recovery (CRi), nodular partial remission (nPR), and partial remission (PR), disease progression (PD), and stable disease (SD). The participants with a PR, CRi, PR or nPR are called responders and the participants with SD and PD are called non-responders. From the start of study treatment until earliest date of disease progression or death (up to up to 3 months following last dose of study treatment) No
Secondary Number of Participants With the Indicated Immunoglobulin Heavy Chain Variable Region (IgVH) Testing at Baseline Who Also Had a Clinical Response After Last Dose of Study Treatment Participants with IgVH mutation results as mutated and unmutated status and clinical response after last dose of study treatment were provided. Clinical responses included complete remission (CR), complete response with incomplete bone marrow recovery (CRi), nodular partial remission (nPR), partial remission (PR), disease progression (PD), and stable disease (SD). The participants with a PR, CRi, PR or nPR are called responders and the participants with SD and PD are called non-responders. From the start of study treatment until earliest date of disease progression or death (up to up to 3 months following last dose of study treatment) No
Secondary Number of Participants With Zeta-chain-associated Protein Kinase (ZAP) 70 Testing at Baseline Who Also Had a Clinical Response After Last Dose of Study Treatment ZAP-70 is a protein normally expressed near the surface membrane of T cells and natural killer cells. ZAP-70 in B cells is used as a prognostic marker in identifying different forms of CLL. Participants with ZAP-70 testing results intermediate (Int), positive (Pos) and negative (Neg) at Baseline and who had a clinical response after last dose of study treatment are provided. Clinical responses included complete remission (CR), complete response with incomplete bone marrow recovery (CRi), nodular partial remission (nPR), partial remission (PR), disease progression (PD), and stable disease (SD). The participants with a PR, CRi, PR or nPR are called responders and the participants with SD and PD are called non-responders. From the start of study treatment until earliest date of disease progression or death (up to 3 months following last dose of study treatment) No
Secondary Number of Participants With an Adverse Event of Any Infusion Reactions (IR) or Serious Infusion Reactions (SIR) An Infusion reaction is defined as events occurring after the beginning of an infusion of ofatumumab or within 24 hours following the end of an infusion of bendamustine. From the first dose of study medication to 60 days after the last dose of study medication (up to 24 hours after last dose of study treatment) No
