A Spanish Medical Record Review of Adults With Relapsed or Refractory CD30+ Malignancies When Re-treated With Brentuximab-vedotin

Study Overview
=================
Brief Summary
-----------------
Participants in the study are adults with CD30-positive malignancies which include classical Hodgkin lymphoma (cHL), cutaneous T-cell lymphoma (CTCL): mycosis fungoides (MF) or primarily cutaneous anaplastic large cell lymphoma (pcALCL), or systemic anaplastic large cell lymphoma (sALCL). The main aims of the study are as follows: to learn about the response rates of participants with relapsed or refractory CD30+ malignancies when re-treated with BV. to check for side effects from re-treatment with BV. The study will take place in approximately 30 hospitals in Spain. The study doctors will review each participant's medical record at least 6 months after finishing the last dose of re-treatment with BV. This study is about collecting existing information only; participants will not receive treatment or need to visit a study doctor during this study.

Detailed Description
-----------------
This is an observational, non-interventional, retrospective study in participants with R/R CD30 positive cHL, CTCL (MF and pcALCL) and sALCL who have previously achieved a CR or PR with BV treatment and subsequently experienced disease progression were administered BV retreatment. This study will assess the effectiveness and safety of BV retreatment in the Spanish population in real-world clinical practice. The study will enroll approximately 35 participants. The data will be collected and recorded from the medical record of participants and also recorded in electronic case report forms (e-CRFs). All the participants will be assigned to a single observational cohort: • Participants With CD30-positive Lymphoma This multi-center trial will be conducted in Spain. The overall duration of the study will be approximately 24 months (12 months for medical chart review and 12 until publication submission).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Participants With CD30-positive Lymphoma<br>All participants diagnosed with relapsed/refractory (R/R) cHL, CTCL (mycosis fungoides [MF] and cutaneous anaplastic large cell lymphoma [pcALCL]) and sALCL with CD30 positive, and who have previously achieved a CR or PR with BV treatment and subsequently experienced disease progression/relapse and were administered BV retreatment will be observed retrospectively from their initiation of BV treatment until participant's inclusion date in the study or until treatment discontinuation due to toxicities or any cause. All study data will be collected retrospectively from the medical records. | Other: No Intervention<br>* This is a non-interventional study.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall Response Rate (ORR) as Assessed by Investigator Based on Positron Emission Tomography/Computerized Tomography (PET/CT) Status | ORR is the percentage of participants whose best overall response (graded by favorability in the order of clinical response [CR], partial response [PR], stable disease [SD], progressive disease [PD], and not evaluable [NE]) from initiation of BV retreatment to the discontinuation or end of treatment according to response criteria is either CR or PR. ORR will be assessed by investigator using 5-point scale for visually assessing response on the pre and end-of-treatment PET/CT scans. The 5-point scale ranges from: 1 (No uptake), 2 (Uptake less than or equal to [<=] mediastinum), 3 (Uptake greater than [>] mediastinum but <=liver), 4 (Uptake moderately >liver), and 5 (Uptake markedly higher than liver and/no new lesions). Total score ranges from 0-5. In case of unavailability of PET/CT scans, ORR will be assessed as per Revised Criteria for Response Assessment for Malignant Lymphoma. Index date: eligible participants who start BV as retreatment. | Up to 6 months post-index date or death, whatever come first | 
| Number of Participants Reporting one or More Adverse Events (AEs) |  | Up to 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Duration of Response (DOR) Based on PET/CT Status | DOR will be calculated as the time (months) from the first documentation of a confirmed CR or PR (whichever is first recorded) to the date of objective PD or death from any cause, whichever is earliest. DOR will be assessed by investigator using 5-point scale for visually assessing response on the pre and end-of-treatment PET/CT scans. The 5-point scale ranges from: 1 (No uptake), 2 (Uptake <=mediastinum), 3 (Uptake >mediastinum but <=liver), 4 (Uptake moderately >liver), and 5 (Uptake markedly higher than liver and/no new lesions). Total score ranges from 0-5. In case of unavailability of PET/CT scans, DOR will be assessed as per Revised Criteria for Response Assessment for Malignant Lymphoma. Index date: eligible participants who start BV as retreatment. | Up to 6 months post-index date or death, whatever come first | 
| Overall Survival (OS) | OS will be calculated as time (months) from the index date (date of initiation of BV as retreatment) to the date of death from any cause or end of follow-up. Participants alive at the end of the study period will be censored. Index date: eligible participants who start BV as retreatment. | From the index date to the date of death from any cause or end of follow-up (up to 6 months) | 
| Percentage of Participants With Complete Response Based on PET/CT Status | Complete response will be assessed by investigator using 5-point scale for visually assessing response on the pre and end-of-treatment PET/CT scans. The 5-point scale ranges from: 1 (No uptake), 2 (Uptake <=mediastinum), 3 (Uptake >mediastinum but <=liver), 4 (Uptake moderately >liver), and 5 (Uptake markedly higher than liver and/no new lesions). Total score ranges from 0-5. In case of unavailability of PET/CT scans, complete response will be assessed as per Revised Criteria for Response Assessment for Malignant Lymphoma. Index date: eligible participants who start BV as retreatment. | At the end of retreatment (up to 6 months post-index date or death, whatever come first) | 
| Time to Clinical Response (CR or PR) | Time to clinical response will be calculated from the date of index date (date of initiation of BV as retreatment) to the date of documented CR or PR. Index date: eligible participants who start BV as retreatment. | From the index date to the date of documented CR or PR (up to 6 months) | 
| Time to Best Response | Time to best response will be calculated as the time from the index date (date of initiation of BV as retreatment) to first documentation of best response documented. Tumor response will be based on tumour assessments carried out as per local practice. Index date: eligible participants who start BV as retreatment. | From the index date to first documentation of best response documented (up to 6 months) | 
| Time to Treatment Failure (TTF) | TTF will be calculated as the time from the index date (date of initiation of BV as retreatment) to first documentation of objective tumor progression or the day of death due to all causes whichever comes earlier. Tumor response will be based on tumour assessments carried out as per local practice. Index date: eligible participants who start BV as retreatment. | From the index date to first documentation of objective tumor progression or the day of death due to all causes (up to 6 months) |
