B-CD30 + Hodgkin Lymphoma International Multi-center Retrospective Study of Treatment Practices and Outcomes

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to describe progression-free survival (PFS) in participants with relapsed or refractory classical Hodgkin lymphoma (RRHL), defined as the time from initiation of first treatment for RRHL to first documentation of relapse or disease progression, or death.

Detailed Description
-----------------
This is a retrospective, non-interventional study of participants with newly-diagnosed cHL, or with RRHL. The study will review the medical records of participants to describe participant's demographics, disease characteristics, treatments received, outcomes, health resources used by the participants, and adverse events that are associated with treatments, and resources used for treatment. The study will enroll approximately 50 to 100 participants in each group at each of the 13 participating countries. Based on the diagnosis of the disease, participants will be assigned to one of the following groups: Group 1: cHL Group 2: RRHL This multi-center trial will be conducted in Argentina, Australia, China, Colombia, Hong Kong, Mexico, Republic of Korea, Russia, Saudi Arabia, Singapore, South Africa, Taiwan, and Turkey. The data for Group 1 and Group 2 will be collected from date of cHL or RRHL diagnosis until the date of death (or the date when the participant was last known to be alive, whichever occurs first).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Group 2, RRHL: Progression Free Survival (PFS) | PFS was defined as time from initiation of frontline regimen to first documentation of relapse or disease progression or death, censored at date of most recent follow-up/contact. Progressive disease (PD) was defined as any new lesion or increase by >=50% of previously involved site from nadir, and was evaluated based on International Working Group (IWG) criteria (Cheson et al 2007). Median PFS was estimated using the Kaplan-Meier method. | From initiation of first treatment until first documentation of relapse/PD/until date of death (or date when participant was last alive), whichever occurred first (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Group 1, cHL: Number of Participants Based on Clinical Staging According to Ann Arbor Staging at Diagnosis | The Ann Arbor staging system of lymphomas is used to summarize the extent of the cancer's spread. Stages are classified by Roman numerals I (lessspread) to IV (more spread). Additional sub staging variables include: A, asymptomatic; and B, presence of B symptoms (including fever, night sweats and weight loss of >=10 percent [%] of body weight over 6 months). | Day 1 at cHL diagnosis | 
| Group 2, RRHL: Number of Participants Based on Clinical Staging According to Ann Arbor Staging at Diagnosis | The Ann Arbor staging system of lymphomas is used to summarize the extent of the cancer's spread. Stages are classified by Roman numerals I (lessspread) to IV (more spread). Additional sub staging variables include: A, asymptomatic; and B, presence of B symptoms (including fever, night sweats and weight loss of >=10 % of body weight over 6 months). | Day 1 at RRHL diagnosis | 
| Group 2, RRHL: Number of Participants Based on Clinical Staging According to Ann Arbor Staging at Relapse After First Relapse or Refractory Diagnosis | The Ann Arbor staging system of lymphomas is used to summarize the extent of the cancer's spread. Stages are classified by Roman numerals I (less spread) to IV (more spread). Additional sub staging variables include: A, asymptomatic; and B, presence of B symptoms (including fever, night sweats and weight loss of >=10% of body weight over 6 months). | At second, third, fourth, and fifth relapse (up to 9 years 10 months) | 
| Group 1, cHL: Number of Participants Based on Each International Prognostic Score (IPS) Category | IPS score was calculated based on following factors: age >=45 years, male sex, stage IV disease, albumin<4 gram per liter (g/L), white blood cell (WBC)>=15*10^9 per liter (/L), haemoglobin <10.5 g/L, and lymphocyte count<0.6*10^6/L or <8% of differential. One point was assigned for each of above factors. The sum of points allotted correlates with following risk groups: good risk (0-1 points)-5 year survival of 89-90%; fair risk (2 to 3 points)-5 year survival of 78-81%; poor risk (4-7 points)-5 year survival of 56-61%. Total score range is 0 to 7, lower scores indicate higher survival rate. | Day 1 at cHL diagnosis | 
| Group 1, cHL: Number of Participants With B Symptoms at Diagnosis | The Ann Arbor staging system of lymphomas is used to summarize the extent of the cancer's spread.

| Group 1, cHL: Number of Participants Based on Best Clinical Response Post Completion of Frontline Treatment | Best clinical response as complete remission (CR), partial remission (PR), stable disease (SD), or PD was evaluated based on IWG criteria (Cheson et al 2007). CR was the disappearance of all evidence of disease. PR was the regression of measurable disease and no new sites. SD was defined by failure to achieve CR, PR, or PD. PD was defined as any new lesion or increase by >=50% of previously involved sites from nadir. | From post completion of frontline treatment until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 2, RRHL: Number of Participants With Best Clinical Response Post Completion of Each Line of Treatment | Best clinical response as CR, PR, SD, or PD was evaluated based on IWG criteria (Cheson et al 2007). CR was the disappearance of all evidence of disease. PR was the regression of measurable disease and no new sites. SD was defined by failure to achieve CR, PR, or PD. PD was defined as any new lesion or increase by >=50% of previously involved sites from nadir. | From post completion of frontline treatment until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Mean Duration of Best Response | Duration of best response was defined as the time from when the criteria for response (CR or PR) were met to first documentation of relapse or disease progression, and was evaluated based on IWG criteria (Cheson et al 2007). CR was the disappearance of all evidence of disease. PR was the regression of measurable disease and no new sites. PD was defined as any new lesion or increase by >=50% of previously involved sites from nadir. | From CR or PR until first documentation of relapse or disease progression or until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Median Overall Survival (OS) | Median OS was defined as the time from diagnosis of cHL to death(Group 1)/ time from first relapse after frontline therapy to death (Group 2), censored at date of most recent follow-up/contact. | From initial diagnosis until the date of death (or date when the participant was alive) (Group 1); From first relapse after frontline therapy to death (Group 2) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 1, cHL: Overall Survival Rate After Diagnosis at 1 and 5 Years | Percentage of participants who were alive at 1 and 5 years after diagnosis in cHL participants are reported. 5 year overall survival data were reported only for participants who had >5 year observation periods. | At 1 year and 5 years after diagnosis (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 2, RRHL: Overall Survival Rate at 1 and 5 Years | Percentage of participants who were alive at 1 and 5 years after diagnosis in RRHL participants are reported. 5 year overall survival data were reported only for participants who had >5 year observation periods. | At 1 year and 5 years after relapse (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 1, cHL: Number of Participants Who Had Inpatient Hospital Admissions, Emergency Room Visits, and Outpatient Visits by Healthcare Professionals Related to HL |  | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 1, cHL: Number of Participants Categorized Based on Reasons for Inpatient Hospital Admissions Related to HL |  | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 1, cHL: Mean Overall Length of Stay and Length of Stay by Unit/Ward for Inpatient Hospital Admissions Related to HL | Length of stay by unit or ward included general, high dependency/intermediate, intensive care unit, bone marrow transplant unit, and emergency visits. | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 1, cHL: Number of Participants Categorized Based on Episodes of RT Received, Type of Scan or Procedure, and Who Received Granulocyte-colony Stimulating Factor (G-CSF) or High-cost Medicines and Pegylated G-CSF Related to HL |  | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 1, cHL: Mean Number of Courses of Treatment With G-CSF/Pegylated G-CSF or Other High-cost Medicines Related to HL Treatment |  | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 2, RRHL: Number of Participants Who Had Inpatient Hospital Admissions, Emergency Room Visits, and Outpatient Visits by Healthcare Professional Related to HL for Salvage Therapy and ASCT | Each participant had more than one category presented for salvage therapy and ASCT. | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 2, RRHL: Number of Participants Categorized Based on Reasons for Inpatient Hospital Admissions Related to HL for Salvage Therapy and ASCT | Each participant had more than one category presented for salvage therapy and ASCT. | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 2, RRHL: Mean Overall Length of Stay and Length of Stay by Unit/Ward for Inpatient Hospital Admissions Related to HL for Salvage Therapy and ASCT | Length of stay by unit or ward included general, high dependency/intermediate, intensive care unit, bone marrow transplant unit, and emergency visits. Each participant had more than one category presented for salvage therapy and ASCT. | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 2, RRHL: Number of Participants Categorized Based on Episodes of RT, Type of Scan or Procedure, and Who Received G-CSF or High-cost Medicines Related to HL for Salvage Therapy and ASCT | Each participant had more than one category presented for salvage therapy and ASCT. Scan procedures included chest x-ray, magnetic resonance imaging, needle biopsy, bone scan, bone marrow aspiration, flow cytometry, and other scan procedures. | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) | 
| Group 2, RRHL: Group 2, RRHL: Mean Number of Courses of Treatment With G-CSF/Pegylated G-CSF or Other High-cost Medicines Related to HL Treatment for Salvage Therapy and ASCT |  | From initial diagnosis until the date of death (or the date when the participant was last known to be alive) (observed retrospectively from 2010 until date of data collection [up to 9 years 10 months]) |
