Frequently asked questions about TOUR006

What is TOUR006 used for?

TOUR006 is an investigational small molecule being studied for chronic kidney disease and thyroid eye disease. It is in Phase 2 clinical development for both indications. In chronic kidney disease, it is being evaluated in patients with elevated high-sensitivity C-reactive protein, and in thyroid eye disease, it is being studied in participants aged 18 to 80 years.

Who makes TOUR006?

TOUR006 is being developed by Tourmaline Bio, Inc., a biopharmaceutical company traded on the stock exchange under the ticker symbol TRML. The company is conducting clinical trials to evaluate the safety and efficacy of TOUR006 in chronic kidney disease and thyroid eye disease.

What phase is TOUR006 in?

TOUR006 is in Phase 2 clinical development. It is being studied in two separate Phase 2 trials: one for thyroid eye disease and one for chronic kidney disease with elevated high-sensitivity C-reactive protein. The drug is investigational and has not been approved by regulatory authorities.

What clinical trials is TOUR006 in?

TOUR006 is being studied in two Phase 2 clinical trials. NCT06088979 evaluates its efficacy and safety in participants with thyroid eye disease, with an enrollment of 79. NCT06362759 evaluates it in patients with chronic kidney disease and elevated high-sensitivity C-reactive protein, with an enrollment of 143. Both trials are randomized, double-blind, and placebo-controlled.

Is TOUR006 the same as TOUR006 - 20 MG?

Yes, TOUR006 - 20 MG is an alternative name for TOUR006. The drug is also referred to by this name, which likely indicates a specific dosage form or strength. Both names refer to the same investigational drug being developed by Tourmaline Bio, Inc.

What does TOUR006 target?

The specific molecular target of TOUR006 is not disclosed in the available information. The drug is described as a small molecule, but its mechanism of action has not been publicly detailed. Clinical trials are evaluating its effects in chronic kidney disease and thyroid eye disease.
