  • Previously received ≥ 1 line of adequate systemic anti DLBCL therapy, defined as an anti CD20 antibody based chemoimmunotherapy for ≥ 2 consecutive cycles, unless participants had PD before Cycle 2.
  • Relapsed or refractory disease before study entry, defined as either:
  • Recurrent disease after having achieved disease remission (complete response or partial response) during or at the completion of the latest treatment regimen.
  • Stable disease or progressive disease (PD) at the completion of the latest treatment regimen.
  • Ineligible for high dose therapy/hematopoietic stem cell transplantation
  • Measurable disease as assessed by computed tomography (CT) or magnetic resonance imaging (MRI) and defined as at least 1 lymph node > 1.5 cm in the longest diameter and/or at least 1 extranodal lesion > 1.0 cm in the longest diameter, and measurable lesion (s) in 2 perpendicular diameters

Exclusion criteria

  • Current or history of central nervous system lymphoma
  • Histologically transformed lymphoma
  • Receipt of the following treatment:
  • Systemic chemotherapy, targeted small molecule therapy or radiation therapy within 4 weeks (or 5 half lives, whichever is shorter) before first dose of study drug
  • Recent treatment with another monoclonal antibody within 4 weeks before first dose of study drug
  • Investigational treatment within 4 weeks (or 5 half lives, whichever is shorter) before first dose of study drug
  • Treatment with autologous stem cell transplantation within 6 months before first dose of study drug
  • Treatment with allogeneic hematopoietic stem cell transplantation or organ transplantation
  • Treatment with anti-programmed cell death protein-1 (PD-1), anti PD-L1, anti PD-L2, anti T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif (ITIM) domain (TIGIT), anti CTLA4 or other antibody or drug specifically targeting T cell costimulation or checkpoint pathways.
  • Active autoimmune diseases or history of autoimmune diseases that may relapse, with the following exceptions:
  • Controlled Type 1 diabetes
  • Hypothyroidism (provided that it is managed with hormone replacement therapy only)
  • Controlled celiac disease
  • Skin diseases not requiring systemic treatment (eg, vitiligo, psoriasis, or alopecia)
  • Any other disease that is not expected to recur in the absence of external triggering factors

Primary outcomes

  1. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Time frame: From first dose of study drug up to 30 days after last dose, maximum time on treatment was 98 weeks.

    An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study drug(s), whether considered related to study drug(s) or not.

    An SAE is any untoward medical occurrence that, at any dose:

    • Resulted in death
    • Was life-threatening
    • Required hospitalization or prolongation of existing hospitalization
    • Resulted in disability/incapacity
    • Was a congenital anomaly/birth defect
    • Was considered a significant medical AE by the investigator based on medical judgement (eg, may jeopardize the patient or may require medical/surgical intervention to prevent one of the outcomes listed above).

  2. Recommended Phase 2 Dose (RP2D) of Ociperlimab When Administered in Combination With Tislelizumab or Rituximab

    Time frame: 21 days

    The highest dose evaluated for which the estimated toxicity rate is closest to the target toxicity rate of 33.3%

Secondary outcomes

  1. Overall Response Rate (ORR)

    Time frame: From first dose of study drug to the data cutoff date of 30 August 2024; maximum time on study was 28 months.

    ORR is defined as the percentage of participants who achieved a best overall response of partial response (PR) or complete response (CR) based on the Lugano classification as assessed by the investigator. Response was evaluated using computed tomography (CT) and metabolic imaging (fluorodeoxyglucose-positron emission tomography (FDGPET).

    CR: complete metabolic (no/minimal FDG uptake and no evidence of FDG-avid disease in bone marrow) and radiologic response (target lesions regressed to ≤ 1.5 cm in longest diameter with no extra-lymphatic sites of disease, no organ enlargement and normal bone marrow morphology), no new lesions, and no bone marrow involvement confirmed by bone marrow biopsies (if bone marrow was involved at baseline).

    PR is partial metabolic (reduced FDG uptake from Baseline) and radiologic response (≥ 50% decrease in size of measurable nodes and extranodal sites, no increase in lesions, and spleen regressed by > 50% in length beyond normal) and no new lesions.

  2. Complete Response Rate (CRR)

    Time frame: From first dose of study drug to the data cutoff date of 30 August 2024; maximum time on study was 28 months.

    CRR is defined as the percentage of participants who achieved a complete response per the Lugano Classification (2014) as assessed by the investigator.

  3. Duration of Response (DOR)

    Time frame: Up to the data cutoff date of 30 August 2024; maximum time on study was 28 months.

    DOR is defined as the time from the date that response criteria were first met to the date that progressive disease is objectively documented per Lugano Classification (2014), as assessed by the investigator, or death, whichever occurred first. Median DOR was estimated using the Kaplan-Meier method.

  4. Time to Response (TTR)

    Time frame: From first dose of study drug to the data cutoff date of 30 August 2024; maximum time on study was 28 months.

    TTR is defined as the time from study treatment start to date of the earliest qualifying response (partial response or better) per Lugano Classification (2014) as assessed by the investigator

  5. Progression-free Survival (PFS)

    Time frame: From first dose of study drug to the data cutoff date of 30 August 2024; maximum time on study was 28 months.

    PFS is defined as the time from first dose until first documentation of progression per Lugano Classification (2014), as assessed by the investigator, or death, whichever comes first. Median PFS was estimated using the Kaplan-Meier method.

  6. Overall Survival (OS)

    Time frame: From first dose of study drug to the data cutoff date of 30 August 2024; maximum time on study was 28 months.

    OS is defined as the time from first study drug administration to the date of death due to any cause. Median OS was estimated using the Kaplan-Meier method.

  7. Serum Concentration of Ociperlimab

    Time frame: Predose and end of infusion (EOI) on Cycle 1 Day 1 (C1D1), Cycle 2 Day 1, Cycle 5 Day 1, Cycle 9 Day 1, and Cycle 17 Day 1

  8. Host Immunogenicity: Number of Participants With Anti-drug Antibodies (ADA) to Ociperlimab

    Time frame: From first dose of study treatment to 30 days after last dose; maximum time on treatment was 98 weeks

    The number of participants with anti-drug antibodies to ociperlimab includes participants that were ADA-negative at Baseline and ADA-positive after drug administration during the treatment or follow-up observation period and participants who were positive at Baseline for ADA and with significant increases (4-fold or higher) in ADA titer after drug administration during the treatment or follow-up observation period.
