Targeting One of the Most Aggressive Brain Cancers

A new approach to treating glioblastoma by overcoming resistance at its core

GBM

Understanding Glioblastoma

Glioblastoma (GBM) is the most aggressive and common form of malignant brain cancer in adults. It is characterized by rapid growth, complex biology, and a high rate of recurrence.

Despite advances in surgery, radiation, and chemotherapy, outcomes remain poor, and effective long-term treatment options are limited.

The Challenge

Why Glioblastoma Is So Difficult to Treat

Glioblastoma presents multiple challenges that limit the effectiveness of conventional therapies:
These factors make GBM one of the most difficult cancers to treat successfully.

A Different Strategy for a Complex Disease

Tactical Therapeutics is developing CTO, a novel therapy designed to target calcium (ca)²⁺ signaling—a central mechanism involved in tumor growth and resistance.

Rather than focusing on a single pathway, CTO works across multiple biological processes, aiming to disrupt the tumor’s ability to survive and adapt.

Why CTO Matters for GBM

Designed for Brain Tumors

CTO offers several key advantages that make it especially promising for glioblastoma treatment:

Clinical Progress

Encouraging Results in Advanced Patients

Clinical studies of CTO have shown promising outcomes in patients with advanced solid tumors, newly diagnosed and recurrent glioblastoma.

one-year survival rate
93%
two-year survival rate
69%
Complete and partial responses observed in heavily pretreated patients
These results support the potential of CTO to significantly impact patient outcomes.

Advancing Toward the Future of GBM Treatment

Tactical Therapeutics is continuing to advance its clinical program with the goal of bringing CTO to patients in need.

By targeting the underlying mechanisms of resistance, we aim to redefine what is possible in the treatment of glioblastoma.

Glioblastoma has long been one of the most challenging cancers to treat. Tactical Therapeutics is working to change that—through innovation, precision science, and a commitment to better outcomes.
