Study Endpoints

Primary Endpoints

Confirmed Objective Response Rate (cORR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) Per Investigator Assessment
From start of study treatment until CR or PR (maximum up to 15.2 months)

cORR is defined as the percentage of participants achieving a confirmed complete response (CR) or partial response (PR) according to RECIST v1.1. CR: disappearance of all target, non-target lesions, all lymph nodes must be non-pathological in size (\<10 millimeter \[mm\] short axis), PR: at least 30% decrease in sum of diameters of target lesions, taking as reference baseline sum diameters persistence of one or more non-target lesions.

Secondary Endpoints

Number of Participants With Treatment Emergent Adverse Events (TEAEs), Treatment Related TEAEs, Greater Than or Equal to (>=) Grade 3 TEAEs, Treatment Emergent Serious Adverse Event (TESAE), Treatment Related TESAE
From first dose of the study treatment (Day 1) up to approximately 18.5 months
Number of Participants With Grade Shift From Baseline to Maximum Post-Baseline in Serum Chemistry Laboratory Abnormalities Assessed by NCI CTCAE
Baseline up to approximately 15.8 months
Number of Participants With Grade Shift From Baseline to Maximum Post-Baseline in Hematology Parameters Assessed by NCI CTCAE
Baseline up to approximately 15.8 months

Frequently asked questions about SEA-CD40

What is SEA-CD40 used for?

SEA-CD40 is an investigational oncology drug being studied for the treatment of Myelodysplastic Syndrome and Melanoma. It is a small molecule being developed by Pfizer, Inc. (NYSE: PFE). The drug is currently in Phase 2 clinical development and is not yet approved by the FDA.

What does SEA-CD40 target?

SEA-CD40 is a small molecule that targets CD40, a protein involved in immune system regulation. By modulating this target, the drug aims to enhance the body's immune response against cancer cells. This mechanism is being explored in clinical trials for conditions like Melanoma and Myelodysplastic Syndrome.

Who makes SEA-CD40?

SEA-CD40 is being developed by Pfizer, Inc., a global biopharmaceutical company traded on the New York Stock Exchange under the ticker symbol PFE. Pfizer is conducting clinical trials to evaluate the safety and efficacy of SEA-CD40 in various oncology indications.

What phase is SEA-CD40 in?

SEA-CD40 is currently in Phase 2 clinical development. It is an investigational drug, meaning it has not yet received regulatory approval. The drug is being studied in clinical trials for the treatment of Myelodysplastic Syndrome and Melanoma, with ongoing research to assess its safety and effectiveness.

What clinical trials is SEA-CD40 in?

SEA-CD40 is being evaluated in two clinical trials. NCT04227847 is a Phase 1 study of SEA-CD70 in patients with Myelodysplastic Syndrome and Acute Myeloid Leukemia, with 178 participants. NCT04993677 is a Phase 2 study of SEA-CD40 given with other drugs in cancers including Melanoma and Non-Small-Cell Lung, with 77 participants.

Is SEA-CD40 the same as SEA-CD70?

SEA-CD40 is also known as SEA-CD70. Both names refer to the same investigational drug being developed by Pfizer, Inc. The drug is being studied under different names in various clinical trials, but they represent the same therapeutic agent for oncology indications.
