Frequently asked questions about BBO-8520

What is BBO-8520 used for?

BBO-8520 is an investigational small molecule being developed for the treatment of non-small cell lung cancer (NSCLC), including metastatic non-small cell lung cancer and advanced lung carcinoma. It is currently in Phase 1 clinical development for these indications.

What does BBO-8520 target?

BBO-8520 targets KRAS, specifically the KRAS G12C mutation, which is a gene involved in cell growth and division. By targeting this mutated gene, BBO-8520 is designed to interfere with cancer cell proliferation in non-small cell lung cancer.

Who is developing BBO-8520?

BBO-8520 is being developed by BridgeBio Oncology Therapeutics, Inc., a company listed under the ticker symbol BBOT. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with KRAS G12C-mutated non-small cell lung cancer.

What phase is BBO-8520 in?

BBO-8520 is currently in Phase 1 clinical development. It is an investigational drug and has not yet been approved by regulatory authorities. The ongoing Phase 1 trial is recruiting participants to assess the drug's safety, tolerability, and preliminary efficacy.

What clinical trials is BBO-8520 in?

BBO-8520 is being studied in a Phase 1 open-label trial with the identifier NCT06343402. This trial is recruiting adult subjects with KRAS G12C non-small cell lung cancer and aims to enroll approximately 350 participants across the United States, Australia, Canada, Denmark, and Spain.

Is BBO-8520 the same as any other drug?

BBO-8520 is a distinct investigational compound developed by BridgeBio Oncology Therapeutics. It is not known to be the same as any other marketed drug. Its unique mechanism targets the KRAS G12C mutation, which is a specific genetic alteration found in some non-small cell lung cancers.
