This is a phase 2 multi-cohort, un-controlled, non-randomized, open-label, multi-center study that assessed the antitumor activity and safety of non-alpha interleukin (IL-2) SAR444245 with or without other anticancer therapies in participants aged 12 years and older with relapsed or refractory B cell lymphoma. This study was structured as a master protocol with separate sub studies designed to investigate the use of SAR444245 either with or without other anticancer therapies for the treatment of relapsed or refractory B cell lymphoma. Substudy 1-Cohort A aimed to establish safety and preliminary anti-tumor activity for non-alpha interleukin (IL-2) SAR444245 combined with the anti-PD1 antibody, pembrolizumab in trial participants with classic Hodgkin lymphoma (cHL) who are anti-PD-(L)1-naive and have received at least 2 or 3 lines of systemic therapy. Substudy 3-Cohort C1 aims to establish safety and preliminary anti-tumor activity for SAR444245 as monotherapy in trial participants with diffuse large B-cell lymphoma (DLBCL). Trial participants in this study must have received at least 2 lines of systemic therapy and have either stable or progressive disease 1-3 months post Health Authority approved Chimeric Antigen Receptor T-cell (CAR-T) treatment when given as last systemic treatment prior to study enrollment.
The duration of the study for an individual participant started from the signature of the main informed consent and included: a screening period of up to 28 days; a treatment period \[max\] 35 cycles (21 days per cycle) for Cohort A and 52 cycles (14 days per cycle) for Cohort C1 or until occurrence of unacceptable toxicities or until PD; an end-of-treatment visit at least approximately 30 days following the last administration of study drug (or until the participant receives another anticancer therapy, whichever is earlier); and a follow-up visits 3 months after treatment discontinuation and every 3 months thereafter following, until disease progression, or initiation of another antitumor treatment, or death, whichever is earlier.

Complete Response Rate (CRR)
The CRR was defined as the percentage of participants who had a complete response (CR) as the best overall response (BOR) as per Investigator assessment (Lugano response criteria 2014). The BOR was defined as the BOR observed from the date of first study treatment until PD, death, cut-off date or initiation of subsequent anti-cancer therapy, whichever occurred first. CR based on computed tomography (CT)-based response: lymph nodes and extralymphatic sites with target nodes/nodal masses must regress to \<=1.5 centimeter (cm) in longest transverse diameter of a lesion (LDi) and no extralymphatic sites of disease.
Time frame: From first dose of study treatment administration (Day 1) up to approximately 21 months
Objective Response Rate (ORR)
ORR was defined as the percentage of the participants with CR or partial response (PR) as the BOR as per Investigator assessment (Lugano response criteria 2014). The BOR was defined as the BOR observed from the date of first study treatment until PD, death, cut-off date or initiation of subsequent anti-cancer therapy, whichever occurs first. CR (CT-based response): lymph nodes and extralymphatic sites with target nodes/nodal masses must regress to \<=1.5cm in LDi and no extralymphatic sites of disease. PR (CT-based response): lymph nodes and extralymphatic sites with \>=50% decrease in sum of the product of the perpendicular diameters for multiple lesions (SPD) of upto 6 target measurable nodes and extranodal sites. A lesion too small to measure on CT, 5 millimeter (mm) X 5mm used as default value. No longer visible, 0 X 0 mm. A node \>5mm X 5mm, but smaller than normal, actual measurement used.
Time frame: From first dose of study treatment administration (Day 1) up to maximum exposure of study treatment; approximately 28 months
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)
An AE was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An SAE was any AE that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was an important medical event. TEAEs were defined as AEs that developed, worsened (according to the Investigator's opinion) or became serious during the TE period.
Time frame: From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment; approximately 29 months
Number of Participants With Dose Limiting Toxicities (DLTs)
Selected events that occurred during the DLT observation period were considered as DLT unless due to PD or to a cause obviously unrelated to pegenzileukin. Selected events included: grade 4 neutropenic fever, grade 4 thrombocytopenia associated with clinically significant bleeding that required clinical intervention, grade 3 or above alanine aminotransferase or aspartate aminotransferase in combination with a bilirubin \>2 × upper limit of normal with no evidence of cholestasis or another cause, such as viral infection or other drugs, grade 3 or above vascular leak syndrome, grade 3 or above hypotension, grade 3 or above cytokine release syndrome, grade 3 or above AE that did not resolve to grade \<=2 within 7 days of starting accepted standard of care medical management.
Time frame: From Day 1 to Day 21 of Cycle 1 (each cycle is 21 days)
Time to Response (TTR)
The TTR was defined as the time from the first administration of study treatment to the first tumor assessment at which the overall response was recorded as PR or CR determined by Investigator (Lugano response criteria 2014). CR (CT-based response): lymph nodes and extralymphatic sites with target nodes/nodal masses must regress to \<=1.5cm in LDi and no extralymphatic sites of disease. PR (CT-based response): lymph nodes and extralymphatic sites with \>=50% decrease in sum of the product of the perpendicular diameters for multiple lesions (SPD) of upto 6 target measurable nodes and extranodal sites. A lesion too small to measure on CT, 5 millimeter (mm) X 5mm used as default value. No longer visible, 0 X 0 mm. A node \>5mm X 5mm, but smaller than normal, actual measurement used.
Time frame: From first dose of study treatment administration (Day 1) up to maximum exposure of study treatment; approximately 28 months
Duration of Response (DoR)
The DoR was defined as the time from the first tumor assessment at which the overall response was recorded as PR or CR until PD determined by Investigator (Lugano response criteria 2014), or death from any cause, whichever occurred first.

BOR was defined as BOR observed from date of first study treatment until PD, death, cut-off date or initiation of subsequent anti-cancer therapy, whichever occurred first. CR (CT-based response): lymph nodes and extralymphatic sites with target nodes/nodal masses must regress to \<=1.5cm in LDi and no extralymphatic sites of disease. PR (CT-based response): lymph nodes and extralymphatic sites with \>=50% decrease in SPD of upto 6 target measurable nodes and extranodal sites. A lesion too small to measure on CT, 5mm X 5mm used as default value. No longer visible, 0 X 0 mm. A node \>5mm X 5mm, but smaller than normal, actual measurement used. SD (CT-based response): \<50% decrease from baseline in SPD of up to 6 dominant, measurable nodes and extranodal sites; no criteria for PD met.
Time frame: From first dose of study treatment administration (Day 1) up to maximum exposure of study treatment; approximately 28 months
Progression Free Survival (PFS)
The PFS was defined as the time from the date of first study treatment administration to the date of the first documented PD determined by Investigator (Lugano response criteria 2014), or death due to any cause. PFS (CT-based response): An individual node/lesion had to be abnormal with: LDi \>1.5 cm and increased by \>=50% from positron emission tomography nadir and an increase in LDi or shortest axis perpendicular to the LDi from nadir, 0.5cm for lesions \<=2 cm, 1.0cm for lesions\>2 cm. In the setting of splenomegaly, the splenic length must be increased by \>50% of the extent of its prior increase beyond baseline. If there was no prior splenomegaly, increase by at least 2 cm from baseline. For new lesions regrowth of previously resolved lesions: a new node \>1.5 cm in any axis, a new extranodal site\>1.0 cm in any axis.
Time frame: From first dose of study treatment administration (Day 1) up to maximum exposure of study treatment; approximately 28 months
