Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Percentage of Participants With a Complete Remission (CR) or Partial Remission (PR)
Tidsramme: Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
Percentage of participants with a CR, PR at the end of the first cycle of treatment (Week 4).
CR was defined as the complete disappearance of all objective disease findings, including enlarged lymph nodes, hepatomegaly, and splenomegaly for at least 4 weeks, and a normalization of blood counts with granulocytes >1.500/ microliter (µL), hemoglobin (Hb) >12 grams per deciliter (g/dL), and platelets >100,000/µL.
PR was defined as a less than (<) 50% regression of all measurable and evaluable lymphoma manifestations (sum of the products of the 2 largest diameters vertical to each other) for at least 4 weeks without the appearance of new manifestations, and normalization of blood counts.

Number of Participants With a Clinical Response
Tidsramme: Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
Clinical response was defined as the best response after the first 4 weeks of treatment cycle by the following categories: CR, PR, minor response (MR), stable disease (SD), and progressive disease (PD).
CR was defined as the complete disappearance of all objective disease findings, including enlarged lymph nodes, hepatomegaly, and splenomegaly for at least 4 weeks, and a normalization of blood counts with granulocytes >1,500/μL, Hb >12 g/dL, and platelets >100,000/μL.
PR was defined as <50% regression of all measurable and evaluable lymphoma manifestations (sum of the products of the 2 largest diameters vertical to each other) for at least 4 weeks without the appearance of new manifestations, and normalization of blood counts.
MR was defined as tumor regression ≥25% and <50%.
SD was defined as tumor regression <25%, no new manifestations, and progression ≤25%.
PD was defined as no new lymphoma associated symptoms or an increase in the size of manifestations by more than 25%.

Time to Best Response
Tidsramme: Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
The median time, in months, from start of the treatment (first application) until best response (PR or CR).
|
Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
|
Duration of Remission
Tidsramme: Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
Median time, in months, between the documentation of CR or PR and PD in clinical responders.
|
Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
|
Time to Progression
Tidsramme: Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
The median time, in months, from the start of treatment (first application) until detection of PD.
|
Treatment start until progression of disease or last available follow-up. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
|
Overall Survival (OS)
Tidsramme: Enrollment into study until end of follow-up or death. The median length of follow-up was 6.6 months (range: 0-97.8 months)
|
OS was defined as the time, in months, between enrollment into the study and death, due to any cause.
Participants who were not reported as having died at the time of the analysis were censored using the date they were last known to be alive.

Number of Participants With a Clinical Response to Re-Treatment
Tidsramme: First application in the second treatment cycle until progression of disease. The median length of follow-up was 4.6 months (range: 0.5-20.6 months).
|
Clinical response was defined as the best response after the second 4 weeks of treatment cycle by the following categories: CR, PR, MR, SD, and PD.
CR was defined as the complete disappearance of all objective disease findings, including enlarged lymph nodes, hepatomegaly, and splenomegaly for at least 4 weeks, and a normalization of blood counts with granulocytes >1,500/μL, Hb >12 g/dL, and platelets >100,000/μL.
PR was defined as <50% regression of all measurable and evaluable lymphoma manifestations (sum of the products of the 2 largest diameters vertical to each other) for at least 4 weeks without the appearance of new manifestations, and normalization of blood counts.
MR was defined as tumor regression ≥25% and <50%.
SD was defined as tumor regression <25%, no new manifestations, and progression ≤25%.
PD was defined as no new lymphoma associated symptoms or an increase in the size of manifestations by more than 25%.
