Show all 16Show fewer
  • Other past or current malignancy (with the exception of basal cell carcinoma or the skin or in situ carcinoma of the cervix or breasts) unless the tumor was successfully treated with curative intent at least 2 years prior to trial entry except if in the opinion of the investigator and medical monitor it is thought not to affect the subject's safety, the conduct of the study or the interpretation of the data
  • Clinically significant cardiac disease, including unstable angina, acute myocardial infarction within 6 months prior to screening, congestive heart failure, and arrhythmia requiring therapy, with the exception of exta systoles or minor conduction abnormalities except if in the opinion of the investigator and medical monitor it is thought not to affect the subject's safety, the conduct of the study or the interpretation of the data
  • History of significant cerebrovascular disease or event with symptoms or sequelae
  • Significant concurrent, uncontrolled medical condition that in the opinion of the investigator or GSK medical monitor contraindicates participation in this study
  • Other anti-leukemic use of medications including glucocorticoids
  • Known HIV positive
  • Screening laboratory values: platelets <50 x 10x9/L, neutrophils<1.0 x 10x9/L, Creatinine > 1.5 X upper normal limit (unless normal creatinine clearance), total bilirubin >1.5 X upper normal limit, ALT >2.5 X upper normal limit (unless due to liver involvement of CLL), alkaline phosphase > 2.5 X upper normal limit
  • Known or suspected hypersensitivity to ofatumumab that in the opinion of the investigator or medical monitor contraindicates study participation
  • Subjects who have received treatment with any non-marketed drug substance or experimental therapy within 5-terminal half-lives or 4 weeks whichever is longer prior to first dose of study medication or currently participating in any other interventional clinical study
  • Lactating women, women with a positive pregnancy test at Visit 1 or women (of childbearing potential) as well as men with partners of childbearing potential, who are not willing to use adequate contraception from study start through one year following last ofatumumab dose. Adequate contraception is defined as abstinence, oral hormonal birth control, implants of levonorgestrel, estrogenic vaginal ring, percutaneous contraceptive patches, intrauterine device, and male partner sterilization if male partner is sole partner for that subject. For females in the USA, the use of a double barrier method is also considered adequate (condom or occlusive cap plus spermicidal agent).

About this study

Official title: A Phase III, Open Label, Randomized, Multicenter Trial of Ofatumumab Maintenance Treatment Versus no Further Treatment in Subjects With Relapsed Chronic Lymphocytic Leukemia (CLL) Who Have Responded to Induction Therapy

The purpose of this study was to determine if maintenance therapy with ofatumumab would prolong remission in patients with CLL who have responded to second or third line treatment. This study would also evaluate the safety of ofatumumab maintenance compared to observation (the current standard of care). This study was co-developed with the HOVON and NORDIC CLL group and would be conducted as a collaborative effort with GSK.

Read the detailed description

The study met its primary objective at the protocol defined interim analysis (data cut-off 19-Jun-2014). The protocol-defined final analysis of the primary endpoint was performed when 280 PFS events were reached (data cut-off 20-Feb-2017).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression-free Survival, as Assessed by the Investigator

    Progression-free survival is defined as the time from randomization to the date of disease progression (PD) or death due to any cause. PD was determined by the investigator according to the definitions of response in the International Workshop for Chronic Lymphocytic Leukemia (IWCLL) updated National Cancer Institute-Sponsored Working Group (NCI-WG) guidelines. According to the guidelines, PD is characterized by at least one of the following: lymphadenopathy (appearance of any new lesion such as enlarged lymph nodes (>1.5 centimeter [cm]), spleen or liver or other infiltrates or an increase by 50% or more in the greatest diameter of any previous site); an increase by 50% or more in the previously noted enlargement of the liver or spleen; an increase by 50% or more in the numbers of blood lymphocytes with at least 5000 lymphocytes per microliter; transformation to a more aggressive histology, or occurrence of cytopenia attributable to chronic lymphocytic leukemia.

    Measured: From randomization until progression or death (up to 79 months)

  2. Progression-free Survival, as Assessed by the Independent Review Committee (IRC)

    Progression-free survival is defined as the time from randomization to the date of disease progression (PD) or death due to any cause. PD was determined by the IRC according to the definitions of response in the International Workshop for Chronic Lymphocytic Leukemia (IWCLL) updated National Cancer Institute-Sponsored Working Group (NCI-WG) guidelines. According to the guidelines, PD is characterized by at least one of the following: lymphadenopathy (appearance of any new lesion such as enlarged lymph nodes (>1.5 centimeter [cm]), spleen or liver or other infiltrates or an increase by 50% or more in the greatest diameter of any previous site); an increase by 50% or more in the previously noted enlargement of the liver or spleen; an increase by 50% or more in the numbers of blood lymphocytes with at least 5000 lymphocytes per microliter; transformation to a more aggressive histology, or occurrence of cytopenia attributable to chronic lymphocytic leukemia.

    Measured: From randomization until progression or death (up to 79 months)

Secondary outcomes (25)
  1. Overall Survival

    Overall survival is defined as time from randomization to date of death.

    Measured: From randomization until death (up to 88 months)

  2. Number of Participants With Improvement in Response From Baseline

    Improvement in response was assessed by calculating the percentage of participants who changed from partial response (PR) at Baseline to complete response during the study.

    Measured: From Baseline until the end of the study (up to 88 months)

  3. Time to Next Therapy

    Time to next therapy is defined as the time from randomization to the date of receiving the next CLL treatment.

    Measured: From randomization until the end of the study (up to 88 months)

  4. Progression-free Survival After Next-line Therapy

    Progression-free survival after next-line therapy is defined as the time from randomization until progression or death following the next-line therapy and counted as events deaths prior to next-line therapy. Participants who received next-line therapy and who did not have progression or death after next-line therapy were censored at their last date of contact. Participant who died prior to next-line therapy, was counted as an event.

    Measured: From randomization until progression or death (up to 88 months)

  5. Time to Progression After Next-line Therapy

    Time to progression after next-line therapy is defined as the time from progression following randomization until progression or death following next-line therapy and counted as events deaths prior to next-line therapy. Participants who received next-line therapy with a PD prior to receiving next line therapy and who did not had progression or death after next-line therapy were censored at their last date of contact. If a participant died prior to next-line therapy, this was counted as an event.

    Measured: From randomization until progression or death (up to 88 months)

  6. Change From Baseline (BL) in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Chronic Lymphocytic Leukaemia 16 Item Module (EORTC QLQ-CLL 16)

    The EORTC QLQ-CLL16 is comprised of 16 questions that address 5 domains of health-related quality of life (HRQoL) important in CLL. There are 4 multi-item scales - fatigue (2 items), treatment side effects ([TSE], 4 items), disease symptoms (disease effects scale [DES], 4 items), and infection (4 items) - and single-item scales (social activities [Social Problems (SP) Scale] and future health worries [Future Health (FH) Scale]). These are measured on a four-point Likert scale, where 1 = not at all and 4 = very much. These scores are transformed to give a rating from 0 - 100, where 0 = no symptoms or problems and 100 = severe symptoms or problems. Changes from Baseline were analyzed by a mixed model-repeated measures analysis of covariance (ANCOVA).

    Measured: From randomization until the end of the study (up to 47 months)

  7. Change From Baseline in the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) Score

    The EORTC QLQ-C30 is a self-reported, 30-item cancer-specific instrument that assesses 15 domains: physical functioning (5 items), role functioning (2 items), emotional functioning (4 items), cognitive functioning (2 items), social functioning (2 items), pain (2 items), fatigue (3 items), nausea and vomiting (2 items), five single-item symptom scores (insomnia, loss of appetite, constipation, diarrhea, and dyspnea), a single item asking about financial difficulties, and global health status/quality of life (QOF) consisting of 2 items. Functional and symptoms scales were measured on a four-point Likert scale, where 1 = not at all and 4 = very much, whereas global health status or QOF was assessed using a 7-item Likert scale, ranging from "poor" (worse quality of life) to "excellent" (better quality of life). Changes from Baseline were analyzed by mixed model-repeated measures ANCOVA.

    Measured: From randomization until the end of the study (up to 47 months)

  8. Change From Baseline in the Quality of Life Status as Assessed by the EuroQol-5D (EQ-5D) Scale

    EQ-5D is comprised of a 5-item health status measure and a visual analogue scale (VAS) and is used to generate two scores: the utility score and the thermometer score. The utility score measures mobility, self-care, usual activities, pain, discomfort, and anxiety/depression. Responses to each of the 5 health states are measured on a 3-point scale (level 1 = no problem; level 2 = some or moderate problem[s] and level 3 = unable, or extreme problems). Responses are typically converted into health utilities or valuations on a scale ranging from 0 (worst health) to 1 (perfect health). The thermometer score ranges from 0 (worst imaginable health state) to 100 (best imaginable health state). Changes from Baseline were analyzed by mixed model-repeated measures ANCOVA. A negative adjusted mean change from Baseline represents a worsening of quality of life.

    Measured: From screening until the end of the study (up to 47 months)

  9. Number of Participants With an Improvement in Eastern Cooperative Oncology Group (ECOG) Performance Status at the Indicated Time Points

    Measured: From first dose of study medication until 60 days after the last dose of study medication or until the last observation at Visit 14 (up to 26 months)

  12. Number of Participants With Any Adverse Event (AE) or Serious Adverse Event (SAE)

    An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or important medical events that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed. Refer to the general Adverse AE/SAE module for a complete list of AEs and SAEs.

    Measured: From first dose of study medication until 60 days after the last dose of study medication or until the last observation at Visit 14 for AEs (up to 26 months) and until end of study for SAEs (88 months)

    Participants who received at least one transfusion (any blood products or blood supportive care product) during the study are presented.

    Measured: From randomization until the end of the study (up to 88 months)

  15. Number of Participants Diagnosed With Autoimmune Hemolytic Anemia (AIHA)

    AIHA is a disease where the body's immune system fails to recognize red blood cells as "self" and begins destroying these red blood cells. The number of participants diagnosed with AIHA are presented.

    Measured: From randomization until the end of the study (up to 88 months)

  16. Number of Participants With a Positive Anti-ofatumumab Antibody (Human Anti-human Antibody; HAHA) Result

    All serum samples for analysis of HAHA were first tested in a screening step; positive samples from the screening were further evaluated in a confirmation test. The confirmed positive samples were reported as HAHA positive and further evaluated in the titration test to obtain a titer of HAHA. A confirmed positive result at any time point means the participant is positive for HAHA.Results are reported as the number of participants positive for HAHA.

    Measured: Pre-dose (Visit 1), Months 7, 13, 19, and 25 during treatment and at 3 and 6 months after last ofatumumab dose (up to 30 months)

  17. Mean Change From Baseline in the Immunoglobulin (Ig) Antibodies IgA, IgG, and IgM at Indicated Time Points

    Immunoglobulins, or antibodies, are large proteins used by the immune system to identify and neutralize foreign particles such as bacteria and viruses. Their normal blood levels indicate proper immune status. Low levels indicate immuno-suppression. IgA, IgG, and IgM were measured in the blood samples of the participants. Baseline IgA, IgG, and IgM values are the last pre-dose assessment values performed on Cycle 1 Day 1. Change from Baseline was calculated as the post-baseline value minus the Baseline value.

    Measured: Baseline, every six months during treatment, and after last treatment visit and/or upon relapse (up to 88 months)

  18. Number of Participants Who Were Positive and Negative for Minimal Residual Disease (MRD) at Any Visit

    MRD refers to small number of leukemic cells that remain in the participant during treatment or after treatment at the time the participant achieved a confirmed complete remission. Number of participants who were positive and negative for minimal residual disease (MRD) at any visit is presented.

    Measured: From randomization until the end of the study (up to 88 months)

  19. Change From Baseline in Cluster of Differentiation (CD) CD5+CD19+ and CD5-CD19+ Cell Counts at the Indicated Time Points

    CD5+CD19+ cells were counted by flow cytometry. Flow cytometry is a technique for counting and examining microscopic particles with an electronic detection apparatus. Baseline CD5+CD19+ and CD5-CD19+ cell count value is the last pre-dose assessment values performed on Cycle 1 Day 1. Change from Baseline was calculated as the post-Baseline value minus the Baseline value.

    Measured: Baseline and every two months from Month 3 until Month 25 and at every followup (up to 88 months)

  20. Summary of Covariates to Compute Cox Proportional Hazards Regression Model for Relationship Between Investigator Assessed Progression-free Survival and the Indicated Prognostic Markers

    Blood samples were collected for the assessment of the following prognostic markers at Baseline (BL) and upon relapse: immunoglobulin heavy chain variable region (IgVH) mutational status; VH3-21 usage; Cytogenetics (by fluorescent in situ hybridization [FISH]) including 6q-, 11q-, +12q, 17p-, 13q- deletions; beta 2 microglobulin. Cox-regression model was used to explore the relationship between progression-free survival and the following explanatory variables: treatment group, cytogenetics (analyzed by FISH) at BL, IgVH mutational status at BL, beta 2 microglobulin at BL, BL CD20 and BL complement level. For each covariate, a hazard ratio <1 indicates a lower risk on the first effect tested compared with the other effects tested. Cytogenetics Group (based on >=20%)=CY G.

    Measured: From Baseline until the end of the study (up to 79 months)

  21. Cmax and Ctrough of Ofatumumab

    Blood samples were collected to assess the plasma concentration of ofatumumab. Maximum concentration (Cmax) and observed drug concentration prior to the next dose (Ctrough) were determined.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 30 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 203 sites in United States, Netherlands, France, Israel, Poland and 20 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Apr 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free Survival, as Assessed by the Investigator (time frame: From randomization until progression or death (up to 79 months)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jul 2019.
