Frequently asked questions about IMC-R117C

What is IMC-R117C used for in cancer?

IMC-R117C is an investigational small molecule being developed for the treatment of cancer, specifically in patients who are HLA-A*02:01-positive. It is currently being studied in a Phase 1/2 clinical trial for selected advanced cancers. The drug is not yet approved and remains in clinical development.

What does IMC-R117C target?

IMC-R117C targets PIWIL1, a protein involved in cancer biology. By targeting PIWIL1, the drug aims to interfere with cancer cell processes. This mechanism is being evaluated in a Phase 1/2 trial for advanced cancers in HLA-A*02:01-positive patients.

Who is developing IMC-R117C?

IMC-R117C is being developed by Immunocore Holdings plc, a biopharmaceutical company listed on the stock exchange under the ticker IMCR. The company is conducting a Phase 1/2 clinical trial to evaluate the drug in patients with selected advanced cancers.

What phase is IMC-R117C in?

IMC-R117C is in Phase 1/2 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The ongoing trial is recruiting participants with HLA-A*02:01-positive advanced cancers to assess the drug's safety and efficacy.

What clinical trials is IMC-R117C in?

IMC-R117C is being studied in a Phase 1/2 trial with the identifier NCT06840119, titled 'Phase 1/2 Study of IMC-R117C in Selected Advanced Cancers.' The trial is actively recruiting 600 participants aged 18 years and older in Australia, Belgium, Germany, Italy, Netherlands, and Spain.
