A Survey of Brentuximab Vedotin in Pediatric Participants With Hodgkin Lymphoma

Study Overview
=================
Brief Summary
-----------------
This study is a survey in Japan of Brentuximab Vedotin used to treat children or teenagers with Hodgkin lymphoma (HL). The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. The main aim of the study is to check for side effects related from Brentuximab Vedotin especially myelosupression, peripheral neuropathy, and lung disorder. During the study, pediatric participants with HL will take Brentuximab Vedotin injection and AVD treatment (doxorubicin hydrochloride, vinblastine sulfate, and dacarbazine) according to their clinic's standard practice. The study doctors will check for side effects from Brentuximab Vedotin for 26 weeks.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants who Experienced Myelosuppression |  | Up to 26 Weeks | 
| Percentage of Participants who Experienced Peripheral Neuropathy |  | Up to 26 Weeks | 
| Percentage of Participants who Experienced Lung Disorder |  | Up to 26 Weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants with Adverse Event (AE) Leading to Brentuximab Vedotin Discontinuation, Serious Adverse Event (SAE), and Grade 3 or Higher Adverse Event (AE) | An adverse event (AE) is any untoward medical occurrence in a patient administered a medicinal product. An adverse event does not necessarily have a causal relationship with the intervention. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Severity grades will be evaluated as per National Cancer Institute Common Terminology Criteria for Adverse Event (NCI CTCAE). Grade 1 scales as Mild; Grade 2 scales as Moderate; Grade 3 scales as severe or medically significant but not immediately lifethreatening; Grade 4 scales as life-threatening consequences; and Grade 5 scales as death related to AE. | Up to 26 Weeks | 
| Percentage of Participants Who Achieve or Maintain Any Best Response | Best response is defined as the cumulative numbers of participants who achieve each level of best response including complete response (CR), complete response/unconfirmed (CRu), partial response (PR), Stable Disease (SD), Progressive Disease (PD) and Relapsed Disease (RD) after treatment. Best response will be assessed by International Working Group (IWG) criteria or Antitumor effect assessment criteria for pediatric HL of Japan Childhood Leukemia and Lymphoma Study Group (JPLSG) version. | Up to 26 Weeks |
