Glioblastoma Treatment: New Drug Candidate Shows promise in Early Studies

Jupiter, Florida, July 2, 2025 – A potential new treatment for glioblastoma, one of the most aggressive forms of brain cancer, is showing promising results in early studies. Scientists at The Wertheim UF Scripps Institute have developed an experimental medication, MT-125, which appears to make the cancer more vulnerable to both radiation and chemotherapy.The Food and Drug Management (FDA) has approved MT-125 for clinical trials, marking a meaningful step forward in the fight against this devastating disease.

Experimental Drug MT-125 Poised For human Trials

The new drug, MT-125, has shown the ability to make previously drug-resistant glioblastoma cells respond to radiation, according to Courtney Miller, PhD, a professor and academic affairs director at The Herbert Wertheim UF Scripps Institute for Biomedical Innovation & Technology. Furthermore, it impedes the cancer’s capacity to invade other tissues.

According to the American Cancer Society, approximately 14,000 people in the United States are diagnosed with Glioblastoma annually. This form of cancer has a grim prognosis, with average survival rates ranging from just 14 to 16 months.

Novel Approach Targets Cellular Motors

Dr. Miller and her team have been focusing on molecular “motors” within cells, specifically nanoscale proteins known as myosin. These proteins act as miniature machines, converting cellular energy into activity.

Myosin motors play a crucial role in cell movement,connection,and contraction. They are found throughout the body, including the heart, muscles, and brain tissue. The innovative drug candidates are designed to block these myosin motors, possibly disrupting the cancer’s ability to spread and thrive.

Four-Pronged Attack on Glioblastoma

The approach using MT-125 appears to offer a multi-faceted strategy against glioblastoma:

• Enhancing sensitivity to radiation.
• Creating multinucleated cells that are marked for cell death.
• Blocking the cells’ ability to invade other brain areas.
• amplifying the effects of existing chemotherapy drugs.

steven Rosenfeld, MD, PhD, a scientist and neuro-oncologist at the Mayo Clinic in Jacksonville, collaborated on the research. He noted that in mice, combining MT-125 with kinase inhibitors resulted in extended periods without disease progression.

Caution: While results in animal studies are promising, many drugs that show potential in mice do not translate effectively to human trials due to biological differences.

Addressing toxicity Concerns

One of the challenges with any new cancer treatment is toxicity. However, early indications suggest that glioblastoma cells are more sensitive to MT-125 than healthy cells. Additionally, the drug does not remain in the body for extended periods. Pulsed administration over a short duration may mitigate toxicity issues, according to Dr. Rosenfeld.

Did You know? Glioblastoma is the most common malignant primary brain tumor, accounting for approximately 15% of all brain tumors.

The compound MT-125 has been licensed to Myosin Therapeutics, a biotechnology company based in Jupiter, Florida, founded by the scientists involved in its advancement. The company is actively working to initiate first-in-human clinical trials for glioblastoma patients within the coming year.

Pro Tip: Patients interested in clinical trials should consult with their oncologists to determine eligibility and potential benefits.

Future Potential Beyond Glioblastoma

Looking ahead, Dr. Miller believes that MT-125 has the potential to be effective against other aggressive forms of gliomas and other cancers. Parallel studies are also underway to explore the use of a related compound, MT-110, to address drug cravings in individuals with methamphetamine use disorder.

Treatment	Action	Potential Benefits
MT-125	Blocks myosin motors in cancer cells	Increases sensitivity to radiation and chemo, prevents invasion
MT-110	Related compound	Potential to reduce drug cravings (methamphetamine)
Standard Treatments	Surgery, Radiation, Chemotherapy	Prolong survival, reduce tumor size

What are your thoughts on this new potential glioblastoma treatment? How do you think this will impact future cancer treatments?

Understanding Glioblastoma: An Evergreen perspective

Glioblastoma remains one of the most challenging cancers to treat due to its aggressive nature and resistance to conventional therapies. Understanding the biology of glioblastoma is crucial for developing effective treatments.

One key characteristic of glioblastoma is its ability to invade surrounding brain tissue, making complete surgical removal tough. Additionally, the tumor cells can develop resistance to chemotherapy and radiation, further complicating treatment efforts. Ongoing research focuses on identifying new therapeutic targets and developing innovative strategies to overcome these challenges.
