Frequently asked questions about Uliledlimab

What is Uliledlimab used for?

Uliledlimab is an investigational monoclonal antibody being studied in oncology for advanced solid tumors, non-small cell lung cancer, and ovarian cancer. It is being developed for use in combination with other therapies, including sintilimab, toripalimab, atezolizumab, and chemotherapy, in patients with locally advanced unresectable or metastatic disease.

Who is developing Uliledlimab?

Uliledlimab is being developed by NovaBridge Biosciences, which trades under the ticker NBP. The company is the sponsor of the clinical trials evaluating uliledlimab in solid tumors and non-small cell lung cancer.

What phase is Uliledlimab in?

Uliledlimab is in Phase 1 and Phase 2 clinical development. It is an investigational drug and has not been approved by the FDA. The Phase 1 study in advanced solid tumors has been completed, and two Phase 2 trials in non-small cell lung cancer are currently active but not recruiting.

What clinical trials is Uliledlimab in?

Uliledlimab has been evaluated in four clinical trials. NCT07005336 and NCT06984588 are active Phase 2 trials in non-small cell lung cancer in China. NCT05001347 was a completed Phase 2 trial in ovarian cancer and selected solid tumors in the United States. NCT04322006 was a completed Phase 1/2 trial in advanced solid tumors in China.

Is Uliledlimab the same as TJ004309?

Yes, Uliledlimab is also known as TJ004309. Both names refer to the same investigational monoclonal antibody developed by NovaBridge Biosciences. The alternative name TJ004309 appears in earlier clinical trial records, including NCT05001347 and NCT04322006.
