Frequently asked questions about LB2102

What is LB2102 used for?

LB2102 is an investigational therapy being developed for extensive stage small cell lung cancer. It is also being studied in large cell neuroendocrine carcinoma of the lung. The drug is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

What does LB2102 target?

LB2102 targets DLL3, a protein expressed on the surface of certain cancer cells. By directing chimeric antigen receptor T-cells against DLL3, the therapy aims to recognize and attack DLL3-positive tumor cells in extensive stage small cell lung cancer and large cell neuroendocrine carcinoma of the lung.

Who makes LB2102?

LB2102 is being developed by Legend Biotech Corporation, a biopharmaceutical company listed on the stock exchange under the ticker LEGN. The company is conducting clinical trials to evaluate the safety and efficacy of LB2102 in patients with extensive stage small cell lung cancer.

What phase is LB2102 in?

LB2102 is in Phase 1 clinical development. It is an investigational drug, meaning it has not yet been approved by the FDA or other regulatory agencies. The ongoing Phase 1 trial is active but not recruiting participants, and the drug is being studied in the United States.

What clinical trials is LB2102 in?

LB2102 is being evaluated in a Phase 1 clinical trial with the identifier NCT05680922. The trial is titled 'DLL3-Directed Chimeric Antigen Receptor T-cells in Subjects With Extensive Stage Small Cell Lung Cancer' and is enrolling approximately 41 participants aged 18 years and older in the United States.

Is LB2102 the same as a DLL3-directed CAR T-cell therapy?

Yes, LB2102 is a DLL3-directed chimeric antigen receptor (CAR) T-cell therapy. It is designed to target the DLL3 protein, which is found on cancer cells in extensive stage small cell lung cancer and large cell neuroendocrine carcinoma of the lung. The therapy is currently in Phase 1 clinical trials.
