After decades of slow progress and high trial failure rates, glioblastoma (GBM) research is experiencing renewed momentum driven by improved clinical trial designs and strategic investments. Industry leaders like Merck and Jazz Pharmaceuticals have made high-profile acquisitions targeting GBM therapeutics, including a $1.3 billion deal by Merck for Modifi Biosciences and Jazz’s $925 million acquisition of Chimerix. Nonprofits are catalyzing funding streams, boosting interest in this challenging brain cancer. Despite historical setbacks and low median survival rates around 14.6 months, these developments signal a cautiously optimistic phase focused on overcoming previous market risks and scientific hurdles.
