What is Zn-Telomir used for in triple-negative breast cancer?

Zn-Telomir is being studied as an oral monotherapy for patients with advanced or metastatic triple-negative breast cancer (TNBC). The Phase 1 trial enrolls adults aged 18 years and older with these conditions. Because it remains investigational, no approved use in TNBC or any other indication has been established.

Who makes Zn-Telomir?

Zn-Telomir is developed by Telomir Pharmaceuticals, Inc., which trades under the ticker TELO. The company is the sponsor of the clinical program evaluating the drug in triple-negative breast cancer.

What phase is Zn-Telomir in?

Zn-Telomir is in Phase 1 clinical development. It is an investigational small molecule and has not been approved by the FDA or any other regulatory agency. The program currently has one Phase 1 trial, which is active but not yet recruiting participants.

What clinical trials is Zn-Telomir in?

Zn-Telomir is being evaluated in one Phase 1 trial, NCT07581314, titled Oral Zn-Telomir Monotherapy in Patients With Advanced or Metastatic Triple-Negative Breast Cancer (TNBC). The trial has a controlled design, is not yet recruiting, and plans to enroll 76 participants aged 18 years and older.

Is Zn-Telomir biomarker selected?

Yes. The Phase 1 trial of Zn-Telomir, NCT07581314, is biomarker selected, meaning enrollment is guided by a biomarker rather than an unselected patient population. The study evaluates oral Zn-Telomir monotherapy in adults with advanced or metastatic triple-negative breast cancer and plans to enroll 76 participants.
