The Albany Gazette - Telomir Pharmaceuticals Announces New Findings in a Prostate Cancer Model Demonstrating Telomir-1 Also Resets DNA Methylation of Tumor Suppressor Genes Implicated in Two of the Most Persistent Challenges in Oncology-Metastasis and Treatment Resistance

MIAMI, FLORIDA / ACCESS Newswire / October 7, 2025 / Telomir Pharmaceuticals, Inc. (NASDAQ:TELO) ("Telomir" or the "Company"), a preclinical-stage biotechnology company developing therapies that target epigenetic drivers of cancer, aging, and age-related disease, today announced new preclinical results showing that its investigational therapy Telomir-1 reactivated two of the body's most important tumor suppressor genes, MASPIN ("tumor suppressor shield") and RASSF1A ("guardian gene"; also called SERPINB5), through DNA methylation reset in prostate cancer models. By restoring the activity of these genes, Telomir-1 may help prevent cancer spread and improve chemotherapy response

Key New Findings

• MASPIN ("tumor suppressor shield"): MASPIN is a natural defense protein that blocks tumor invasion, regulates cell migration and angiogenesis, promotes apoptosis, and enhances treatment sensitivity. In an aggressive prostate-cancer model in vivo, MASPIN was silenced by DNA hypermethylation. Telomir-1 reversed the chemotherapy-induced DNA methylation to restore MASPIN activity, consistent with reactivation of this key tumor-suppressor pathway.

• RASSF1A ("guardian gene", also called SERPINB5):
  RASSF1A is a critical regulator of cell cycle brakes, apoptosis, and suppression of metastasis. It is commonly silenced in aggressive cancers by hypermethylation. Telomir-1 reduced RASSF1A methylation in a dose-dependent manner, with stronger effects when combined with chemotherapy.

• Implication: These results suggest Telomir-1 may reactivate natural tumor defenses, counteract chemotherapy-induced resistance mechanisms, and help limit metastasis - two of the most persistent challenges in oncology.

Why This Matters

Metastasis is responsible for the vast majority of cancer deaths, and chemotherapy resistance remains a major barrier to durable responses. Tumors often silence genes like MASPIN and RASSF1A by hypermethylation to disable the body's natural defenses.

Telomir-1's ability to reset DNA methylation, restore tumor suppressor activity, and synergize with chemotherapy provides a compelling preclinical rationale for its potential as a first-in-class epigenetic reset therapy in oncology.

Scientific Perspective

"The potential reactivation of MASPIN and RASSF1A by inhibition of hypermethylation is highly significant because these genes play a central role in blocking tumor invasion, uncontrolled growth, and metastasis," said Dr. Itzchak Angel, CSA at Telomir. "By demonstrating that in addition to an effect on DNA methylation of other key proteins, such as STAT1 and CDKN2A, Telomir-1 can also reset DNA methylation and restore the function of these silenced tumor suppressors, we are providing strong mechanistic evidence that this drug candidate could address cancer at its epigenetic roots in a broader manner."

CEO Perspective

"These results highlight Telomir-1's potential to change the way we think about treating cancer and aging," said Erez Aminov, CEO of Telomir. "Instead of only managing disease progression; Telomir-1 may reset the underlying epigenetic programs that drive tumor growth, resistance, and cellular decline. By reawakening the body's natural defenses, this approach could mark a new era in medicine - one where we target the root biology of cancer and age-related disease."

Building on Prior Work

Telomir-1 has previously demonstrated in preclinical studies:

• Reactivating tumor suppressors such as STAT1 (immune surveillance), CDKN2A (cell cycle brake), and TMS1 (apoptosis mediator).

• Histone demethylase inhibition: activity across JMJD3 (KDM6B), UTX (KDM6A), FBXL10 (KDM2B), FBXL11 (KDM2A), and the KDM5 family - enzymes long considered undruggable despite their central role in cancer, inflammation, and resistance.

• Mitochondrial health restoration: improved energy production while reducing oxidative stress (ROS) and avoiding unwanted cell proliferation, suggesting relevance to cancer metabolism as well as Alzheimer's, Parkinson's, ALS, and Progeria.

• Wnt "fuel line" modulation: modest Tankyrase inhibition that may cut off cancer's growth signaling without telomere-shortening toxicity.

• Selectivity advantage: sparing broad acetyltransferases such as GCN5L2, reducing systemic toxicity risk.

• Telomere & aging benefits: elongated telomeres and reversal of epigenetic drift in accelerated-aging models.

• Functional in vivo outcomes: ~50% tumor volume reduction and elimination of chemotherapy-related mortality in aggressive prostate cancer models.

Together, these findings support Telomir-1's emerging profile as a broad-spectrum epigenetic and metabolic reset therapy with potential applications across oncology, neurodegeneration, autoimmune disease, metabolic dysfunction, and aging.

Next Steps

Telomir is advancing Telomir-1 through preclinical development and IND-enabling studies. Additional evaluations are underway in prostate cancer and other aggressive tumor models where epigenetic silencing and metabolic dysfunction drive metastasis and treatment resistance.
