The Fort Worth Press - Telomir Pharmaceuticals Announces FDA Clearance of IND for Telomir-Zn in Triple-Negative Breast Cancer

MIAMI, FL / ACCESS Newswire / April 30, 2026 / Telomir Pharmaceuticals, Inc. (NASDAQ:TELO) ("Telomir" or the "Company"), a clinical-stage biotechnology company developing small-molecule therapeutics targeting epigenetic and metabolic drivers of cancer and age-related disease, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Company's Investigational New Drug (IND) application for its lead candidate, Telomir-Zn, for the treatment of patients with advanced or metastatic triple-negative breast cancer (TNBC).

This IND clearance enables the Company to advance Telomir-Zn into clinical evaluation, representing an important step toward addressing a significant unmet need in patients with advanced or metastatic triple-negative breast cancer, where treatment options remain limited, and outcomes are poor.

IND Clearance and Development Package

The FDA's clearance reflects review of a comprehensive IND submission supporting advancement of Telomir-Zn into clinical evaluation. The submission included pharmacology, toxicology, manufacturing data, and the Company's first-in-human Phase 1/2 clinical study protocol (TELO-001).

The IND package was supported by completed IND-enabling studies, including pharmacology and toxicology evaluations, pharmacokinetic data demonstrating systemic exposure, and preclinical data indicating activity in models of triple-negative breast cancer.

Planned Phase 1/2 Clinical Trial

The planned clinical study (TELO-001) is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of Telomir-Zn as an oral monotherapy in patients with advanced or metastatic TNBC.

Study Overview

• First-in-human, multicenter, open-label Phase 1/2 trial

• Adult patients with advanced or metastatic TNBC who have received prior systemic therapy

• Planned enrollment of approximately 76 patients

Phase 1: Dose Escalation

• Modified 3+3 dose-escalation design

• Evaluation of safety, tolerability, and dose-limiting toxicities

• Determination of maximum tolerated dose and recommended Phase 2 dose

• Assessment of pharmacokinetics, pharmacodynamics, and preliminary antitumor activity

• Integrated biomarker analyses to evaluate epigenetic modulation, gene re-expression, and telomere-related biology associated with cellular aging and genomic stability

Phase 2: Dose Expansion

• Simon's two-stage design to assess preliminary efficacy

• Primary endpoint is objective response rate (ORR)

• Secondary endpoints include duration of response (DoR), progression-free survival (PFS), overall survival (OS), and safety

• The study will incorporate pharmacokinetic, pharmacodynamic, and biomarker analyses to evaluate target engagement and explore potential correlations between epigenetic modulation and clinical outcomes

Translational and Biomarker Strategy

The study includes an integrated biomarker program designed to evaluate pharmacodynamic activity, target engagement, and potential predictors of response.

Biomarker analyses will assess changes in epigenetic regulation, including global DNA methylation, gene re-expression of epigenetically silenced tumor suppressor pathways, and histone modification patterns associated with tumor biology.

In addition, exploratory analyses will evaluate biomarkers related to cellular aging and genomic stability, including telomere dynamics and associated epigenetic signatures, with the objective of understanding the broader biological activity of Telomir-Zn across oncology and age-related pathways.

The study will also assess correlations between biomarker modulation and clinical outcomes, including preliminary antitumor activity, objective response, and progression-free survival, and may inform identification of potential predictive biomarkers of response.

Clinical Development Strategy

The Company plans to initiate the Phase 1/2 clinical trial in the first half of 2026, anchored by a leading U.S. academic medical center, with potential expansion to additional oncology sites.

Mechanism of Action

Telomir-Zn is an investigational small-molecule designed to represent a novel therapeutic approach and a potentially first-in-class strategy focused on modulation of intracellular metal homeostasis and downstream epigenetic regulation.

Unlike conventional cytotoxic chemotherapy, immune checkpoint inhibition, antibody-drug conjugates, or classic epigenetic drugs, Telomir-Zn is being developed to target metal-dependent epigenetic vulnerabilities that may contribute to tumor progression, treatment resistance, genomic instability, and cancer-associated aging biology.

Preclinical studies indicate that Telomir-Zn alters intracellular iron and zinc balance, modulates iron-dependent chromatin-regulating enzymes, and influences gene expression and cellular pathways associated with tumor biology, genomic stability, and cellular aging.

Clinical Context

Breast cancer is the most commonly diagnosed cancer worldwide, with approximately 2.3 million new cases diagnosed annually, according to the World Health Organization.

Triple-negative breast cancer represents approximately 10 to 15 percent of cases and is associated with aggressive disease biology and limited treatment options, particularly in the advanced or metastatic setting.

Despite available therapies, outcomes remain poor, and TNBC continues to represent a multi-billion-dollar global market with significant unmet medical need.

Management Commentary

"The clearance of our IND, including the Phase 1/2 clinical protocol, marks an important step as we advance Telomir-Zn into clinical evaluation," said Erez Aminov, CEO of Telomir.

"Triple-negative breast cancer remains one of the most difficult cancers to treat in the advanced or metastatic setting, with limited options and consistently poor outcomes. There is a clear need for new therapeutic approaches, and we look forward to evaluating Telomir-Zn in this patient population."

Dr. Itzchak Angel, Chief Scientific Advisor, added:

"Telomir-Zn is designed to target fundamental aspects of tumor biology through modulation of intracellular metal balance and epigenetic regulation. This metal-epigenetic approach represents a differentiated therapeutic strategy that may have relevance not only in triple-negative breast cancer but also across broader cancer and age-related disease biology."
