Study Endpoints

Primary Endpoints

Progression-free Survival (PFS)
up to 33.9 months

PFS was defined as the time from the date of randomization to the date of the first documented disease progression (PD), according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) by blinded independent central review committee (BICR), or death due to any cause, whichever occurred first. PD: progression of a target or non-target lesion or presence of a new lesion.

Overall survival was defined as the time between the date of randomization and the date of death due to any cause.

Objective Response Rate (ORR)
From baseline until disease progression or treatment discontinuation, up to 10.3 months

The primary efficacy endpoint for the study is the ORR. The ORR is defined as the number of patients with CR and PR divided by the number of patients in the analysis set. Tumor response will be defined as best response based on local investigator's assessment according to RECIST criteria v.1.1.

1-year Disease-free survival (DFS) by response subgroup
1 year

DFS is defined the occurrence of progression of local disease, distant metastases, second primary or death. 1-year DFS, will be analyzed using the Kaplan-Meier method and be compared using a 0.05-level one-sided two-proportion test. DFS will be compared among the three subgroups: favorable response subgroup, intermediate response subgroup, unfavorable response subgroup.

Objective response rate
Up to 5 years following completion of study treatment

Defined as the proportion of participants having a best objective response of complete response (CR) or partial response (PR), as determined by investigator assessment per Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1.

Frequently asked questions about Retifanlimab

What is retifanlimab?

Retifanlimab is an investigational monoclonal antibody being developed by Incyte Corporation for the treatment of advanced solid tumors and other cancers. It is designed as a PDCD1 antagonist and is being studied across tumor types including anal cancer, endometrial cancer, gastric adenocarcinoma, glioma, and breast cancer. It is not yet approved and remains in clinical development.

What is retifanlimab used for?

Retifanlimab is being studied for advanced solid tumors, including anal cancer, anatomic stage IV breast cancer, endometrial cancer, gastric adenocarcinoma, and glioma. Clinical trials also evaluate it in Merkel cell carcinoma, glioblastoma, and pancreatic adenocarcinoma. It is investigational and has not been approved for any indication.

What does retifanlimab target?

Retifanlimab targets PDCD1, also known as PD-1, and acts as an antagonist of that receptor. By blocking PDCD1, the antibody is intended to interfere with a checkpoint pathway that tumors use to suppress immune responses. This mechanism places retifanlimab in the immune checkpoint inhibitor class of oncology therapies.

Who is developing retifanlimab?

Retifanlimab is being developed by Incyte Corporation, which trades on the Nasdaq under the ticker INCY. Incyte is the sponsor associated with the clinical development program for this monoclonal antibody across multiple solid tumor indications.

What phase is retifanlimab in?
