A Survey of Brentuximab Vedotin in Pediatric Participants With Hodgkin Lymphoma

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.

Time frame: 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.

Time frame: Up to 26 Weeks
