My first thought is that there are lots of proof of concept but no one wants to give money to an effort they won’t get a solo bonanza from. They have to share the win with another. Makes me feel if someone were to buy the property and have complete control, this tech might have greater impact.
It reminds me of book publishing and copyright. I once asked to reproduce a small book that a major publisher had the rights to but would never publish. It was $1.75 on Amazon and would not be available to public for another 20 years. They said they had plans for it but were lying through their teeth. They have no plans and only want control of the rights. There are thousands if not millions of works that are locked behind closed doors of major publishers. Unless they are proven valuable, they will never see the light of day.
Virosomes: Showing Broad Application Prospects in Vaccination and Drug Delivery System
Cancer treatment Several virosome-based agents with high safety profiles have been approved by the United States Food and Drug Administration (FDA) for use in humans. Virosomes are ideal vehicles for delivering immunogenic substances in host bodies due to their reciprocally reinforcing functions when used as vaccines. Virosome vaccines had been used in several preclinical studies and clinical trials for cancer treatment. For example, cervical cancer is one of the cancers that has been successfully treated by immunotherapy of virosome-formulated vaccines.
Besides, virosomes can deliver drugs specifically to the target cancer cells by displaying appropriate molecules (such as antibodies or affibodies) on their surface. Even tumor-specific monoclonal antibody fragments (Fab) can be attached to virosomes to direct the carrier to selected tumor cells.
