Frequently asked questions about EG-70

What is EG-70 used for in Superficial Bladder Cancer?

EG-70 is an investigational small molecule being developed for the treatment of superficial bladder cancer, specifically non-muscle invasive bladder cancer with carcinoma in situ. It is being studied in patients who are BCG-unresponsive, have high-risk NMIBC incompletely treated with BCG, or are BCG-naïve.

Who makes EG-70?

EG-70 is being developed by enGene Holdings Inc., a biopharmaceutical company traded on the stock exchange under the ticker symbol ENGN. The company is conducting clinical trials to evaluate the safety and efficacy of EG-70 in patients with superficial bladder cancer.

What phase is EG-70 in?

EG-70 is currently in Phase 2 clinical development. It is being studied in the LEGEND trial, which is a Phase 1/Phase 2 study. The drug is investigational and has not been approved by regulatory authorities, as it is still undergoing clinical evaluation.

What clinical trials is EG-70 in?

EG-70 is being evaluated in the LEGEND Study (NCT04752722), a Phase 1/Phase 2 trial with an enrollment of 350 participants. The study is recruiting patients with superficial bladder cancer, including non-muscle invasive bladder cancer with carcinoma in situ, and is currently active.

Is EG-70 the same as any other drug?

EG-70 is the primary name for this investigational drug candidate. No alternative names have been established for EG-70 in the available clinical trial information. It is being studied under this name in the LEGEND trial for the treatment of superficial bladder cancer.
