Frequently asked questions about Intismeran

What is Intismeran used for in Non-Small Cell Lung Cancer?

Intismeran is an investigational monoclonal antibody being studied for the treatment of Non-Small Cell Lung Cancer. It is currently in Phase 3 clinical development as an adjuvant therapy for high-risk Stage I disease, meaning it is given after surgery to help prevent the cancer from returning.

What does Intismeran target?

Intismeran is a monoclonal antibody, but its specific molecular target has not been disclosed in the available information. The drug is being evaluated in combination with pembrolizumab coformulated with berahyaluronidase alfa in a Phase 3 clinical trial for Non-Small Cell Lung Cancer.

Who makes Intismeran?

Intismeran is being developed by Merck & Company, Inc., which is publicly traded under the ticker symbol MRK. The company is conducting a Phase 3 clinical trial of the drug as an adjuvant treatment for high-risk Stage I Non-Small Cell Lung Cancer.

What phase is Intismeran in?

Intismeran is in Phase 3 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 3 trial is recruiting patients with high-risk Stage I Non-Small Cell Lung Cancer to evaluate the drug as an adjuvant therapy.

What clinical trials is Intismeran in?

Intismeran is being studied in one active Phase 3 clinical trial with the identifier NCT07513376. This randomized, double-blind, placebo-controlled trial is evaluating adjuvant Intismeran with or without pembrolizumab coformulated with berahyaluronidase alfa in high-risk Stage I Non-Small Cell Lung Cancer, with a planned enrollment of 876 participants.

Is Intismeran the same as V940?

Intismeran is also known as V940, as indicated by the clinical trial title. The Phase 3 study NCT07513376 refers to the drug as Intismeran (V940), confirming that these names refer to the same investigational monoclonal antibody being developed by Merck for Non-Small Cell Lung Cancer.
