Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Progression-Free Survival (PFS), as Assessed by the Independent Review Committee (IRC) | From randomization to the date of first documented disease progression or death due to any cause, whichever occured first, reported between day of first patient randomized up to about 49 months | PFS is defined as the interval of time between the date of randomization and the earlier of the date of disease progression (PD) and the date of death due to any cause. PD requires at least one of the following: lymphadenopathy, appearance of any new lesion such as enlarged lymph nodes (\>1.5 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 leukaemia. Par. who were alive and had not progressed at the time of analysis or if a progression event or death occurred after extensive lost-to-follow-up time or if new anti-cancer therapy was started were censored at the date of the last visit with adequate assessment. |
| Secondary | Number of Participants With the Best Overall Response (OR), as Assessed by the IRC | From randomization until the 259th PFS event occurred, up to about 49 months | OR is defined as the number of participants achieving an objective response (complete response \[CR\], CR with incomplete bone marrow recovery \[CRi\], partial response \[PR\], and nodular PR \[nPR\]). CR (all the criteria at least 2 months after last treatment): no lymphadenopathy (Ly) \> 1.5 cm/ hepatomegaly/ splenomegaly/ constitutional symptoms; neutrophils \>1500 per microliter (µL), platelets (PL) \>100,000/µL, hemoglobin (Hb) \>11 grams/deciliter (g/dL), lymphocytes (LC) \<4000/µL, bone marrow (BM) sample must be normocellular for age, \<30% LC, no lymphoid nodule. CRi: CR criteria, persistent anemia/thrombocytopenia/neutropenia unrelated to CLL but related to drug toxicity. PR: \>=50% decrease in LC, Ly, size of liver and spleen and at least one of the following results: PL \>100,000/µL or 50% improvement over Baseline (BL), Hb \>11 g/dL or 50% improvement over BL. nPR: persistent nodules BM. |
| Secondary | Number of Participants Who Were Negative for Minimal Residual Disease (MRD) | From randomization until the 259th PFS event occurred (Median follow-up approximately 28.9 months) | MRD was performed by flow cytometry on a bone marrow or peripheral blood sample taken at least 2 months after final treatment. MRD negative was defined as less than one CLL cell per 10000 leukocytes. |
| Secondary | Overall Survival | From randomization up to about 111 months | Overall survival is defined as the time from randomization to death due to any cause. Each participant was followed at the time when the total IRC-assessed PFS events occurred. Participants who had not died were censored at the date of last contact. |
| Secondary | Time to Response, as Assessed by the IRC | From randomization uo to about 27 months | Time to response is defined as the time from randomization to the first response (CR, CRi, nPR, or PR). CR (all the criteria at least 2 months after last treatment): no lymphadenopathy (Ly) \> 1.5 cm/ hepatomegaly/ splenomegaly/ constitutional symptoms; neutrophils \>1500 per microliter (µL), platelets (PL) \>100,000/µL, hemoglobin (Hb) \>11 grams/deciliter (g/dL), lymphocytes (LC) \<4000/µL, bone marrow (BM) sample must be normocellular for age, \<30% LC, no lymphoid nodule. CRi: CR criteria, persistent anemia/thrombocytopenia/neutropenia unrelated to CLL but related to drug toxicity. PR: \>=50% decrease in LC, Ly, size of liver and spleen and at least one of the following results: PL \>100,000/µL or 50% improvement over Baseline (BL), Hb \>11 g/dL or 50% improvement over BL. nPR: persistent nodules BM. Participants with unknown or missing responses were considered as non-responders. Only responders (CR, CRi, PR, nPR) were included in the analysis. |
| Secondary | Duration of Response (DOR), as Assessed by the IRC | From randomization up to about 43 months | DOR is defined as the time from the initial response (CR, CRi, nPR, or PR) to the first documented sign of PD or death due to any cause. PD requires at least one of the following: lymphadenopathy, appearance of any new lesion such as enlarged lymph nodes (\>1.5 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 leukaemia. Par. who were alive and had not progressed at the time of analysis or if a progression event occurred after extensive lost-to-follow-up time (\>= 12 weeks) were censored at the date of the last visit with adequate assessment. Par. with unknown or missing responses were considered as non-responders. |
| Secondary | Time to Progression, as Assessed by the IRC | From randomization up to about 49 months | Time to progression is defined as the time from the date of randomization to disease progression (PD). PD requires at least one of the following: lymphadenopathy, appearance of any new lesion such as enlarged lymph nodes (\>1.5 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 leukaemia. Participants who were alive and had not progressed at the time of analysis or if a progression event occurred after extensive lost-to-follow-up time were censored at the date of the last visit with adequate assessment. |
| Secondary | Time to Next Therapy | From randomization up to about 49 months | Time to next therapy is defined as the time from randomization until the start of the next-line of treatment. |
| Secondary | Number of Participants With Improvement in ECOG Performance Status of 0 or 1 | Baseline, Cycle 3 Day 1, 1 month Follow-up | The ECOG performance status scales and criteria are used by doctors and researchers to assess how a participant's disease is progressing, how the disease affects the daily living, and determines appropriate treatment and prognosis. Grade 0, fully active, able to carry on all pre-disease performance without restriction. Grade 1, restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, e.g., light house work, office work. Grade 2, ambulatory and capable of all selfcare, but unable to carry out any work activities; up and about more than 50% of waking hours. Grade 3, capable of only limited selfcare; confined to bed or chair more than 50% of waking hours. Grade 4, completely disabled; cannot carry on any selfcare; totally confined to bed or chair. Grade 5, dead. Participants with an ECOG performance status of 0 or 1 are shown.. |
| Secondary | Number of Participants With Improvement in Constitutional Symptoms (CS) | Baseline, Cycle 3 Day 1, and 1 month Follow-up | Assessment for the presence of the following symptoms were performed at Screening, Day 1 of each treatment cycle and at every Follow-up visit: night sweats (without signs of infection); unexplained, unintentional weight loss \>= 10% within the previous 6 months; recurrent, unexplained fever of greater than 38 degrees celsius or 100.5 degrees fahrenheit for 2 weeks; and extreme fatigue. The best response refers to overall best response in terms of CR, CRi, PR or nPR. Data are presented for constitutional response= yes and no. |
