Phoenix Biotechnology, Inc. (PBI)'s Focus

Phoenix Biotechnology, Inc., has been exploring the health-related benefits of a novel extract of Nerium oleander for the past 20 years. The company has developed a supercritical CO2 extraction of Nerium oleander into a new botanical drug – PBI-05204.

PBI-05204 is a ‘botanical drug’ that has been through initial FDA review and approved for the Phase I and Phase II clinical trials which were conducted in the United States. These trials have shown that this oral (capsule) formulation is safe for administration to patients without undue toxicity.

A distinction of PBI-05204 is that research has consistently proven that this drug crosses the blood brain barrier which opens up several potential applications. Extensive research has been done in the following areas: Antiviral, Cancer, and Neurodegenerative Diseases.

PBI sponsored research at the University of Texas at San Antonio has demonstrated that PBI-05204 leads to a marked reduction in neuroinflammtion in brain microglial cells in vitro. Importantly, when fed to mice orally the PBI drug also produces a significant reduction in accumulation of beta-amyloid plaques within the brains of specifically bred transgenic mice that develop Alzheimer’s-like disease. Taken together ,these recent findings suggest that further exploration of the utility of PBI-05204 for neurodegenerative diseases like Alzheimer's is warranted.
