Frequently asked questions about CHS-114

What is CHS-114 used for?

CHS-114 is an investigational small molecule being developed for the treatment of advanced solid tumors and metastatic solid tumors. It is currently in Phase 1 clinical development and has not been approved by the FDA. The drug is being studied in patients with conditions such as head and neck squamous cell carcinoma.

What does CHS-114 target?

CHS-114 targets CCR8, a protein involved in immune regulation. By targeting CCR8, the drug aims to modulate the tumor microenvironment, potentially enhancing the body's immune response against cancer cells. This mechanism is being evaluated in clinical trials for advanced solid tumors.

Who makes CHS-114?

CHS-114 is being developed by Coherus Oncology, Inc., a subsidiary of Coherus BioSciences (NASDAQ: CHRS). The company is conducting Phase 1 clinical trials to evaluate the safety and efficacy of CHS-114 in patients with advanced solid tumors.

What phase is CHS-114 in?

CHS-114 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA and is still being studied in clinical trials. The ongoing trials are recruiting participants with advanced solid tumors to assess the drug's safety, tolerability, and preliminary efficacy.

What clinical trials is CHS-114 in?

CHS-114 is being studied in two Phase 1 clinical trials. NCT05635643 evaluates CHS-114 as a monotherapy in participants with advanced solid tumors, including head and neck squamous cell carcinoma. NCT06657144 studies CHS-114 (also known as tagmokitug) in combination with toripalimab and/or other treatments in participants with advanced or metastatic solid tumors.

Is CHS-114 the same as tagmokitug?

Yes, CHS-114 is also known as tagmokitug. This alternative name appears in clinical trial records, where the drug is referred to as CHS-114 (Tagmokitug) in combination studies. Both names refer to the same investigational small molecule targeting CCR8.
