结局指标
主要结局
Overall Response Rate (ORR) as Per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria
时间窗: Up to 76 months
ORR was defined as sum of participants with partial responses (PR) and complete responses (CR). CR: No evidence of new disease; Absolute lymphocyte count(ALC)\<4x10\^9/liter(L); Regression of all target nodal masses to ≤1.5 centimeters (cm) in longest diameter(LD); Normal spleen,liver size; Regression to normal of all nodal non-target disease and disappearance of all detectable; Non-nodal, non-target disease; Morphologically negative bone marrow; No lymphoid nodules; Absolute neutrophil count(ANC)\>1.5x10\^9/L,platelets≥100x10\^9/L,hemoglobin (Hgb)≥110 gram per liter(g/L). PR: No evidence of new disease; Response in 2 of following if abnormal at baseline: ALC\<4x10\^9/L or ≥50% decrease from baseline in sum of products(SPD) of target nodal lesions; splenomegaly; hepatomegaly;≥50% decrease from baseline in CLL marrow infiltrate/B-lymphoid nodules; response in any 1:ANC\>1.5x10\^9/L,platelets\>100x10\^9/L,Hgb\>110g/L or ≥50% increase over baseline in any of these.
Progression-Free Survival (PFS) Per iwCLL Criteria
时间窗: Up to 76 months
PFS was defined as the interval from enrollment to the earlier of the first documentation of definitive disease progression (PD) or death from any cause. PD was appearance of new nodes \>1.5 cm in the LD and \>1.0 in longest perpendicular diameter (LPD), new or recurrent hepatomegaly or splenomegaly, new or reappearance of an unequivocal extra-nodal lesion, ≥50% increase from the nadir in the sum of products of diameters (SPD) of target lesions, ≥50% increase in the LD of an individual node or extra-nodal mass, splenic/hepatic enlargement of ≥50% from nadir, unequivocal increase in the size of non-target disease, transformation to a more aggressive histology, decrease in platelet count or Hgb, \>50% decrease from the highest on-study platelet count, \>20 g/L decrease from the highest on-study Hgb.
Duration of Response (DOR)
时间窗: Up to 76 months
DOR:Interval from first documentation of CR/PR to first documentation of PD or death from any cause.CR:ALC\<4x10\^9/L;Regression to normal of target nodal masses,nodal non-target disease,and no detectable non-nodal,non-target disease;Normal spleen,liver size;Morphologically negative bone marrow,No lymphoid nodules;ANC\>1.5x10\^9/L,Platelets≥100x10\^9/L,Hgb≥110 g/L.PR:Response in 2 or more:ALC\<4x10\^9/L, ≥50% drop from baseline in ALC or SPD of target nodal lesions,Hepatosplenomegaly,≥50% decrease from baseline in CLL marrow infiltrate/B-lymphoid nodules;Response in 1 or more:ANC\>1.5x10\^9/L,Platelets\>100x10\^9/L,Hgb\>110 g/L or ≥50% increase over baseline in any.PD:Response in 1 or more:new nodes,Hepatosplenomegaly,unequivocal extra-nodal lesion;≥50% increase from nadir in SPD of target lesions or LD of node/extra-nodal mass or Splenic/Hepatic size,Unequivocal increase in non-target disease,More aggressive histology;Drop of \>50% in platelets/\>20g/L in Hgb from highest on-study count.
Complete Response (CR) Rate Per iwCLL Criteria
时间窗: Up to 76 months
The CR rate was defined as the percentage of participants who achieved CR. CR: No evidence of new disease; ALC \<4 x 10\^9/L; Regression of all target nodal masses to normal size ≤1.5 cm in the LD; Normal spleen and liver size; Regression to normal of all nodal non-target disease and disappearance of all detectable; Non-nodal, non-target disease; Morphologically negative bone marrow; No lymphoid nodules; ANC \>1.5 x 10\^9/L, platelets ≥100 x 10\^9/L, Hgb ≥110 g/L.
