Study Details

Study Description

Brief Summary

The purpose of this study is to determine whether treatment with IBI110 single agent and in combination with sintilimab demonstrates sufficient efficacy/safety in r/r DLBCL.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

This is a phase Ib, open-label, randomized study to determine the efficacy and safety of treatment with IBI110 single agent and in combination with sintilimab in DLBCL that are relapsed and/or refractory to available standard of care therapies.

Participants in each cohort are randomly assigned to one of the two arms: IBI110 single agent arm and IBI110 in combination with sintilimab arm. Participants received study treatment for a maximum of 2 years, or until disease progression (assessed by investigator per Lugano 2014 Criteria for Malignant Lymphoma (Cheson et al 2014)), unacceptable toxicity, death or discontinuation from study treatment for any other reason.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Single agent treatment arm with IBI110

IBI110 administered at RP2D

Drug: IBI110
BI110 is a high-affinity, ligand-blocking, humanized anti- Lymphocyte Activation Gene-3 (LAG-3) IgG4 antibody that blocks the binding of LAG-3 to MHCII.

Experimental: Combination treatment arm with IBI10 and sintilimab

IBI110 and sintilimab administered at RP2D

Drug: IBI110 plus sintilimab
Sintilimab is a NMPA approved high-affinity, ligand-blocking, humanized anti-programmed death-1 (PD-1) IgG4 antibody that blocks the binding of Programmed death-ligand 1 (PD-L1) and programmed death-ligand 2 (PD-L2) to PD-1.

Outcome Measures

Primary Outcome Measures

  1. Objective response rate (ORR) [Up to 24 months]

    Percentage of subjects achieving complete remission and partial remission in the studied cohort

  2. The frequency of adverse events (adverse events, AEs) and serious adverse events (SAEs) [Up to 24 months]

    An adverse event (AE) is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. TEAE were defined as AEs with onset during the treatment period or that are a consequence of a pre-existing condition that has worsened since baseline.

Secondary Outcome Measures

  1. complete response rate [Up to 24 months]

    The percentage of subjects that achieved complete response in the studied cohort

  2. DoR [Up to 24 months]

    DOR is defined as the date of their first objective response (which is subsequently confirmed) to disease progression per the the Lugano 2014 criteria or death regardless of cause.

  3. PFS [Up to 24 months]

    PFS is defined as the time from the treatment date to the date of disease progression per Lugano 2014 criteria or death regardless of cause.

  4. OS [Up to 24 months]

    OS is defined as the time from treatment to the date of death.
