- Sanofi
- Brief Summary
The is a phase 2 multi-cohort, un-controlled, non-randomized, open-label, multi-center study assessing 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 is 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 aims 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.
- Detailed Description
The duration of the study for an individual patient will start from the signature of the main informed consent and include:
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 patient 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.

- Capable of giving signed informed consent
For cohort A: Histologically or cytologically confirmed diagnosis of classic Hodgkin lymphoma (cHL), must have received at least two prior lines of systemic therapy for cHL, including at least one containing an anthracycline or brentuximab.
For cohort C1: Histologically confirmed diagnosis of diffuse large B Cell lymphoma (DLBCL), must have received at least two prior lines of systemic therapy for DLBCL, including one containing a combination of anthracycline and rituximab (or another anti-CD20 agent), with the last line of therapy a Health Authority approved CD19-directed CAR-T therapy. Patients must have BOR (Best Overall Response) of stable disease (SD) or progressive disease (PD) after CD-19 directed CAR-T therapy.
Participants are excluded from the study if any of the following criteria apply:
- Eastern Cooperative Oncology Group (ECOG) performance status of ≥ 2 (≥ 16 years old). Lansky Scale (< 16 years old) ≤ 60%
- Poor bone marrow reserve
- Poor organ function
- Participants with baseline oxygen saturation (SpO2) ≤ 92% (without oxygen therapy)
- Lymphomatous involvement of the central nervous system
- History of allogenic or solid organ transplant
- Prior IV or subcutaneous anticancer therapy, investigational agent, major surgery within 21 days prior to initiation of IMP; oral anticancer therapy within 5 half-lives or completed palliative radiotherapy within 21 days prior to initiation of IMP
- Has received prior IL-2-based anticancer treatment
- Comorbidity requiring corticosteroid therapy
- Antibiotic use (excluding topical antibiotics) ≤ 14 days prior to first dose of IMP
- Severe or unstable cardiac condition within 6 months prior to starting study treatment
- Active, known, or suspected autoimmune disease that has required systemic treatment in the past 2 years-Known second malignancy either progressing or requiring active treatment within the last 3 years
- Receipt of a live or live attenuated virus vaccination within 28 days of planned treatment start. Seasonal flu vaccines or SARS-CoV-2 vaccine that do not contain live virus are permitted

- Primary Outcome Measures
Name Time Method Complete Response Rate- Cohort A Baseline to the date of first documented progression or initiation of subsequent anticancer therapy or approximately 8 months after the last participant receive first dose. Cohorts A:
Complete response rate (CRR) defined as the proportion of participants who have a complete response (CR) determined by Investigator per Lugano response criteria 2014.Objective Response Rate- Cohort C1 Baseline to the date of first documented progression or initiation of subsequent anticancer therapy or approximately 8 months after the last participant receive first dose. Cohort C1:
Objective response rate (ORR) defined as the proportion of participants who have CR or partial response (PR) determined by Investigator per Lugano response criteria 2014.
