GemVax Applies for FDA Breakthrough Therapy Designation for PSP Treatment GV1001

On September 22, GemVax & KAEL announced that it has applied for the U.S. Food and Drug Administration (FDA) Breakthrough Therapy designation for 'GV1001,' its treatment for progressive supranuclear palsy (PSP).

GV1001 has already been designated as a Fast Track and Orphan Drug by the FDA, as well as an Orphan Drug by the European Medicines Agency (EMA). If GV1001 is designated as a Breakthrough Therapy by the FDA, the drug development timeline could be significantly shortened. The Breakthrough Therapy designation is a system designed to accelerate the development and review of drugs that demonstrate substantial improvement over existing therapies for serious diseases, providing institutional support to increase the speed and likelihood of new drug development.

The FDA grants Breakthrough Therapy designation when early clinical data show a clinically significant improvement. This includes cases where the treatment is markedly more effective or significantly safer than existing therapies, or where there are no existing treatments and the drug demonstrates clinically meaningful effects.

GemVax & KAEL demonstrated the potential of GV1001 as a treatment by confirming its tolerability and a trend toward slowing disease progression in a Phase 2a clinical trial for PSP. In an interim analysis that combined six months of data from both the initial and extension trials, the company observed statistically significant effects compared to an external control group.

If designated as a Breakthrough Therapy, the benefits include: ▲ structured support from senior FDA officials ▲ real-time consultation with the FDA on clinical trial design, data collection, and development strategies ▲ rolling review to shorten the review period ▲ eligibility for accelerated approval and priority review, among others.

GemVax & KAEL is already receiving various benefits such as market exclusivity and tax credits through the FDA Fast Track and Orphan Drug designations. If the company also secures Breakthrough Therapy designation, the development of its PSP treatment is expected to accelerate even further.

A GemVax & KAEL representative stated, "We hope that GV1001 will receive the FDA's Breakthrough Therapy designation, one of the agency's most robust new drug development support programs, so that we can provide a fundamental treatment to PSP patients in urgent need as soon as possible."

PSP is the most severe neurodegenerative disorder among Parkinsonian syndromes, and there are currently no approved treatments. The cause of the disease remains unknown. It shares pathophysiological similarities with Alzheimer's disease, including neuroinflammation and neuronal cell death caused by tau protein damage.
