Frequently asked questions about Zimberelimab

What is Zimberelimab used for?

Zimberelimab is an investigational oncology drug being studied for non-small cell lung cancer, lung cancer, and biliary tract carcinoma. It is being evaluated in combination with other therapies, including chemotherapy and domvanalimab, for untreated metastatic non-small cell lung cancer and in other advanced or resectable settings.

What does Zimberelimab target?

Zimberelimab targets PDCD1, also known as programmed cell death protein 1 (PD-1), and acts as an inhibitor. By blocking PD-1, it is designed to enhance the immune system's ability to fight cancer cells. This mechanism is being studied across multiple oncology indications.

Who makes Zimberelimab?

Zimberelimab is being developed by Gilead Sciences, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol GILD. Gilead is conducting clinical trials to evaluate the drug's safety and efficacy in various cancer types.

What phase is Zimberelimab in?

Zimberelimab is currently in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The drug is being studied in active clinical trials for lung cancer and biliary tract carcinoma, with one Phase 3 trial also listed.

What clinical trials is Zimberelimab in?

Zimberelimab is being studied in three active clinical trials. NCT05502237 is a Phase 3 trial in non-small cell lung cancer with 1,021 participants. NCT05633667 is a Phase 2 trial in lung cancer with 192 participants. NCT06048133 is a Phase 2 trial in biliary tract carcinoma with 33 participants.

Is Zimberelimab the same as ZIM?

Yes, Zimberelimab is also known as ZIM. This abbreviation is used in clinical trial contexts and research literature to refer to the same drug. Researchers and clinicians may use either name when discussing the drug's development and study results.
