Frequently asked questions about Iza-bren

What is Iza-bren used for?

Iza-bren is an investigational oncology therapy being studied in breast neoplasms, non-small cell lung cancer, and urothelial cancer. Clinical trials are evaluating it in triple-negative breast cancer, EGFR-mutated non-small cell lung cancer, and metastatic urothelial cancer that has progressed after immunotherapy. It is not yet approved for any indication.

Who makes Iza-bren?

Iza-bren is being developed by Bristol-Myers Squibb Company, which trades under the ticker BMY. The company is running the clinical development program, including the IZABRIGHT series of trials in lung cancer, breast cancer, and urothelial cancer across North America, Europe, and Asia.

What phase is Iza-bren in?

Iza-bren is in Phase 2 development, with individual trials spanning Phase 2 and Phase 3. Two active trials are currently recruiting, and no trials have been completed. The program has enrolled approximately 1,350 participants across randomized, active-controlled studies. Iza-bren is investigational and has not received FDA approval.

What clinical trials is Iza-bren in?

Iza-bren is being studied in four recruiting trials: NCT07680790 (IZABRIGHT-Lung02) in EGFR-mutated non-small cell lung cancer, NCT07100080 (IZABRIGHT-Lung01) in EGFR-mutated NSCLC after EGFR TKI failure, NCT07106762 in metastatic urothelial cancer, and NCT06926868 (IZABRIGHT-Breast01) in triple-negative breast cancer.

Is Iza-bren the same as izalontamab brengitecan?

Yes, Iza-bren is an alternative name for izalontamab brengitecan, which is also identified by the code BMS-986507. All three names refer to the same investigational agent being developed by Bristol-Myers Squibb for breast neoplasms, non-small cell lung cancer, and urothelial cancer.
