Cracking the Glioblastoma Challenge: A CEO's Journey in Brain Cancer Treatment

 

John Climaco, Chairman and CEO of CNS Pharmaceuticals, elaborates on his company's dedicated mission in the research and development of new cancer treatments for the brain and the central nervous system. Climaco, an experienced entrepreneur, was drawn to the immense challenge of glioblastoma, referring to it as an "uncrackable nut" and "the toughest of the tough". He explains that glioblastoma multiforme is the most common and deadly primary brain cancer, which is "essentially uniformly fatal" and often degrades a person before their body succumbs. The standard of care for this disease has remained largely stagnant for the past two decades, and it continues to be a "black box" in oncology with no known precursors or biomarkers.

The primary obstacle in treating brain cancer is the blood-brain barrier, a highly protected sanctuary that makes it "very, very difficult to get therapies through". While glioblastoma tumors are vulnerable to conventional chemotherapies in laboratory settings, their location within the brain, shielded by this barrier, renders them largely untouchable inside the body. CNS Pharmaceuticals addresses this by focusing on molecules specifically designed to bypass this protective network. Their "back to the future" approach involves two unique compounds: Berubicin, a novel anthracycline, and TPI 287, a novel taxane. Both are distinguished by their ability to cross the blood-brain barrier, unlike other drugs in their respective classes. These drugs aim to provide much-needed options for patients experiencing their first disease recurrence, where current therapeutic choices are severely limited.

In terms of development, CNS Pharmaceuticals is advancing a Phase 2 clinical program for TPI 287, with plans to begin dosing patients in the first quarter of the next year and anticipate data by early 2027. They are also closely monitoring the FDA's potential new pathway for "conditional approval," which could be particularly relevant for drugs like Berubicin. Berubicin recently completed a global study showing a 30% improvement in overall survival in patients, although it did not meet the primary endpoint for statistical significance required for traditional approval. This conditional pathway is specifically intended for rare diseases with few to no treatment options, a description that perfectly fits glioblastoma patients.

Climaco highlights the company's lean operational philosophy, with a small team of only five remote members, ensuring that "all of the money gets poured into the programs" rather than extraneous infrastructure. This focus is paramount given the significant capital burn rate inherent in drug development. Their approach to risk mitigation emphasizes a highly collaborative and senior team that is encouraged to challenge assumptions and adapt course as needed, fostering a culture of humility and continuous improvement.

The decision to fund the company through public markets, rather than venture capital, was deliberate. Climaco notes that public funding has allowed them to continue financing their challenging work, especially given the historical reluctance of venture capital to invest heavily in glioblastoma due to high failure rates. Key performance indicators monitored include patient recruitment during trials and maintaining sufficient cash reserves. Despite the constant headwinds and inherent risks of their business, Climaco expresses that he sleeps well at night, knowing that they are "doing our very best" and remain true to their mission. He draws inspiration from the patients who face long odds with deep acceptance, stating that if they can accept what's out of their control, then he can certainly "accept what's out of mine".
