Frequently asked questions about Lutetium rhPSMA-10.1

What is Lutetium rhPSMA-10.1 used for in prostate cancer?

Lutetium rhPSMA-10.1 is an investigational small molecule being studied for the treatment of prostate cancer, including metastatic castration-resistant prostate cancer (mCRPC). It is currently in Phase 1 clinical development and is not yet approved by regulatory authorities.

What does Lutetium rhPSMA-10.1 target?

Lutetium rhPSMA-10.1 is a radiopharmaceutical that targets prostate-specific membrane antigen (PSMA), a protein highly expressed on prostate cancer cells. By binding to PSMA, it delivers a radioactive payload (lutetium-177) directly to the tumor cells.

Who is developing Lutetium rhPSMA-10.1?

Lutetium rhPSMA-10.1 is being developed by cbdMD, Inc., a company traded on the stock exchange under the ticker symbol YCBD. The company is conducting clinical trials to evaluate the drug's safety and efficacy in prostate cancer.

What phase is Lutetium rhPSMA-10.1 in?

Lutetium rhPSMA-10.1 is currently in Phase 1 clinical trials. It is an investigational drug, meaning it has not yet received FDA approval and is still undergoing clinical development to assess its safety and effectiveness.

What clinical trials is Lutetium rhPSMA-10.1 in?

Lutetium rhPSMA-10.1 is being studied in a Phase 1 trial with the identifier NCT05413850, titled 'Anti-tumour Activity of (177Lu) rhPSMA-10.1 Injection'. This trial is recruiting 82 male participants aged 18 and older with prostate cancer, including mCRPC, and is being conducted in the United States, Belgium, Germany, Netherlands, and the United Kingdom.

Is Lutetium rhPSMA-10.1 the same as Lutetium (177Lu) rhPSMA-10.1 Injection?

Yes, Lutetium rhPSMA-10.1 is also known as Lutetium (177Lu) rhPSMA-10.1 Injection. These names refer to the same investigational drug being developed for prostate cancer.
