An Investigational Immuno-therapy Safety and Effectiveness Study of Nivolumab in Combination With Brentuximab Vedotin to Treat Non-Hodgkin Lymphomas

DLTs are defined as any study drug-related toxicity (brentuximab vedotin or nivolumab) that requires either a dose reduction or delay of more than 7 days of either study drug in Cycle 2 or delays the Cycle 3 Day 1 administration of combined treatment by more than 7 days.

Number of participant Deaths

An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation participant administered study drug and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug.

A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose:

• results in death
• is life-threatening (defined as an event in which the participant was at risk of death at the time of the event; it does not refer to an event which hypothetically might have caused death if it were more severe)
• requires inpatient hospitalization or causes prolongation of existing hospitalization.
• results in persistent or significant disability/incapacity
• is a congenital anomaly/birth defect
• is an important medical event

Number of participants with adverse events leading to discontinuation

Number of participants with adverse events leading to dose delay or reduction

Number of participants with Drug Related Adverse Events

Percentage of participants with specific thyroid test abnormalities

Percentage of participants with specific Liver test abnormalities

The percentage of participants with a best overall response (BOR) of CR or PR.

DLBCL, PTCL, PMBL & MGZL complete and partial response are outlined in the Lugano Classification 2014 and Lymphoma Response to Immunomodulatory therapy Criteria.

CTCL complete and partial response are defined in The consensus Global Response Score assessment.

DOR will be calculated from the date of initial documentation of a response (CR, or PR) to the date of first documented evidence of progressive disease (or relapse for participants who experience CR during the study) or death due to any cause, whichever occurs first.

DLBCL, PTCL, PMBL & MGZL complete and partial response are outlined in the Lugano Classification 2014 and Lymphoma Response to Immunomodulatory therapy Criteria.

CTCL complete and partial response are defined in The consensus Global Response Score assessment.

The CRR is defined as the percentage of participants with a BOR (Best overall response) of CR divided by the number of treated participants.

DLBCL, PTCL, PMBL & MGZL (CR)

1.Complete disappearance of all detectable clinical evidence of disease. 2.Bone marrow: No evidence of FDG- avid disease in marrow. CTCL (CR)

• 100% clearance of skin lesions.
• all lymph nodes ≤1.5 cm, N3 classification and ≤ 1.5 cm in their long axis and > 1 cm in their short axis at baseline, must be ≤ 1 cm in their short axis or biopsy negative for lymphoma.
• organs should not be enlarged on examination or imaging
• absence of blood involvement

The duration of CR will only be evaluated in participants with BOR of CR and is defined as the time from first documentation of CR to the date of relapse or death due to any cause, whichever occurs first.

PFS is defined as the time from the date of first dose of study drug until the date of first documented evidence of progressive disease (or relapse for participants who experience CR during the study) or death due to any cause, whichever comes first. Participants who are progression-free and alive or have unknown status will be censored at the last tumor assessment. Participants who did not have any onstudy tumor assessments and did not die will be censored on the date of first treatment. For participants who received subsequent therapy prior to documented progression, it will be censored on the last tumor assessment date prior to or on subsequent therapy.

OS is defined as the time from the date of first dose of study drug until the date of death (any reason). If the participant is alive or the vital status is unknown, the participant will be censored at the date the participant was last known to be alive.
