A Study of Nivolumab-relatlimab Fixed-dose Combination Versus Regorafenib or TAS-102 in Participants With Later-lines of Metastatic Colorectal Cancer (RELATIVITY-123)

August 5, 2026 updated by: Bristol-Myers Squibb

A Phase 3, Randomized, Open-label Study of Relatlimab-nivolumab Fixed-dose Combination Versus Regorafenib or Trifluridine + Tipiracil (TAS-102) for Participants With Later-lines of Metastatic Colorectal Cancer

The purpose of this study is to evaluate relatlimab in combination with nivolumab, administered as a fixed-dose combination (nivolumab-relatlimab FDC, also referred to as BMS-986213) for the treatment of non-microsatellite instability high (MSI-H)/deficient mismatch repair (dMMR) metastatic colorectal cancer (mCRC) participants who failed at least 1 but no more than 4 prior lines of therapy for metastatic disease.

Description

Inclusion Criteria

  • Histological confirmed previously treated colorectal cancer with adenocarcinoma histology with metastatic or recurrent unresectable disease at study entry.
  • Participants must have:.

    i) progressed during or within approximately 3 months following the last administration of approved standard therapies (at least 1, but not more than 4 prior lines of therapies in the metastatic setting), which must include a fluoropyrimidine, oxaliplatin, irinotecan, an anti-VEGF therapy, and anti-EGFR therapy (if RAS wild-type), if available in the respective country, or;.

ii) been intolerant to prior systemic chemotherapy regimens if there is documented evidence of clinically significant intolerance despite adequate supportive measures.

  • Must have sufficient tumor tissue & evaluable PD-L1 expression to meet the study requirements.
  • Must have measurable disease per RECIST v1.1. Participants with lesions in a previously irradiated field as the sole site of measurable disease will be permitted to enroll provided the lesion(s) have demonstrated clear progression and can be measured accurately.

Exclusion Criteria

  • Prior treatment with either an immunotherapy or with regorafenib or with TAS-102.
  • Untreated central nervous system (CNS) metastases, participants are eligible if CNS metastases have been treated and participants have neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment).
  • History of refractory hypertension not controlled with anti-hypertensive therapy, myocarditis (regardless of etiology), uncontrolled arrhythmias, acute coronary syndrome within 6 months prior to dosing, Class II congestive heart failure (as per the New York Heart Association Functional Classification), interstitial lung disease/pneumonitis or an active, known or suspected autoimmune disease.
  • Confirmed tumor microsatellite instable high/deficient mismatch repair (MSI-H/dMMR) status as per local standard testing; MSI/MMR test results from initial diagnosis are acceptable.
  • Other protocol-defined Inclusion/Exclusion criteria apply.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall Survival (OS)
Time Frame: From date of randomization to the date of death due to any cause (Up to approxaimtely 38 months)
OS is defined as the time from date of randomization to the date of death due to any cause.
From date of randomization to the date of death due to any cause (Up to approxaimtely 38 months)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective Response Rate (ORR) Per Blinded Independent Central Review (BICR)
Time Frame: From randomization until the date of objectively documented response (Up to approximately 38 months)

ORR is defined as the percent of participants with a best overall response (BOR) of confirmed Complete Response (CR) or Partial Response (PR).

CR=Disappearance of all target lesions. PR=At least a 30% decrease in the sum of diameters of target lesions.

From randomization until the date of objectively documented response (Up to approximately 38 months)
Progression Free Survival (PFS) Per Blinded Independent Central Review (BICR)
Time Frame: From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)

PFS is defined as the time from randomization to first documented progression (PD) or death due to any cause, whichever is earlier.

PD=At least a 20% increase in the sum of diameters of target lesions.

From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)
Duration of Response (DoR) Per Blinded Independent Central Review (BICR)
Time Frame: From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)

DoR is defined as the time between the date of first confirmed documented response (CR or PR) to the date of the first documented tumor progression as determined by BICR (per RECIST v1.1 criteria), or death due to any cause, whichever occurs first.

CR=Disappearance of all target lesions. PR=At least a 30% decrease in the sum of diameters of target lesions. PD=At least a 20% increase in the sum of diameters of target lesions.

From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)
Number of Participants With Adverse Events (AEs)
Time Frame: From first dose until 30 days post last dose (Up to 24 months)
AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product; it does not necessarily have to have a causal relationship with this treatment. An SAE is defined as any untoward medical occurrence at any dose that: results in death, is immediately life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity or substantial disruption of the ability to conduct normal life functions, results in a congenital abnormality or birth defect, or is an important medical event that may not result in death, be life-threatening, or require hospitalization, but may require medical or surgical intervention to prevent any of the outcomes listed above.
From first dose until 30 days post last dose (Up to 24 months)
Number of Participants With Select Adverse Events (AEs)
Time Frame: From first dose until 30 days post last dose (Up to 24 months)
AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product; it does not necessarily have to have a causal relationship with this treatment.
From first dose until 30 days post last dose (Up to 24 months)
Number of Participants With Immune Mediated Adverse Events (IMAEs)
Time Frame: From first dose until 30 days post last dose (Up to 24 months)
AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product; it does not necessarily have to have a causal relationship with this treatment.
From first dose until 30 days post last dose (Up to 24 months)
Number of Participants With Laboratory Test Results of Worst Toxicity Grade 3 and 4
Time Frame: From first dose until 30 days post last dose (Up to 24 months)

All abnormalities were graded as per CTCAE v5.0 on a scale from 1 to 4, with Grade 1 being mild and asymptomatic; Grade 2 is moderate requiring minimal, local or noninvasive intervention; Grade 3 is severe or medically significant but not immediately life-threatening; Grade 4 events are usually severe enough to require hospitalization.
From first dose until 30 days post last dose (Up to 24 months)
Time Until Definitive Deterioration - Quality of Life (TUDD-QoL)
Time Frame: From randomization until the first date of a definititve clincial decline from baseline in QoL scale score (Up to approximately 38 months)
TUDD-QoL is defined as time from randomization until the first date of a definitive clinically meaningful decline from baseline in EORTC QLQ-C30 health status/QoL scale score. A definitive deterioration is defined as when all subsequent PRO assessments after a deterioration also reach or exceed the pre-defined meaningful change threshold. A decrease in score of at least 15 points from baseline will be considered to be the meaningful change threshold (MCT) for the global health status/quality-of-life and scale.
From randomization until the first date of a definititve clincial decline from baseline in QoL scale score (Up to approximately 38 months)
Time Until Definitive Deterioration - Physical Function (TUDD-PF)
Time Frame: From randomization until the first date of a definititve clincial decline from baseline in PF scale score (Up to approximately 38 months)
TUDD-PF is defined as time from randomization until the first date of a definitive clinically meaningful decline from baseline in EORTC QLQ-C30 physical function scale score. A definitive deterioration is defined as when all subsequent PRO assessments after a deterioration also reach or exceed the pre-defined meaningful change threshold. A 10-point decrease from baseline will be considered the meaning change threshold (MCT) for the physical function scale.
From randomization until the first date of a definititve clincial decline from baseline in PF scale score (Up to approximately 38 months)
Progression Free Survival (PFS) Per Investigator
Time Frame: From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)

PFS is defined as the time from randomization to first documented progression (PD) or death due to any cause, whichever is earlier.

PD=At least a 20% increase in the sum of diameters of target lesions.

From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)
Objective Response Rate (ORR) Per Investigator
Time Frame: From randomization until the date of objectively documented response (Up to approximately 38 months)

ORR is defined as the percent of participants with a best overall response (BOR) of confirmed Complete Response (CR) or Partial Response (PR).

CR=Disappearance of all target lesions. PR=At least a 30% decrease in the sum of diameters of target lesions.

From randomization until the date of objectively documented response (Up to approximately 38 months)
Duration of Response (DoR) Per Investigator
Time Frame: From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)

DoR is defined as the time between the date of first confirmed documented response (CR or PR) to the date of the first documented tumor progression as determined by BICR (per RECIST v1.1 criteria), or death due to any cause, whichever occurs first.

CR=Disappearance of all target lesions. PR=At least a 30% decrease in the sum of diameters of target lesions. PD=At least a 20% increase in the sum of diameters of target lesions.

From date of randomization to the date of first documented progression or death, whichever occurs first (Up to approximately 38 months)
