A vaccine to prevent and stop melanomas

A vaccine to prevent and stop melanomas

A new anti-cancer vaccine could be the solution to melanomas, composed of two experimental drugs that manage, both prevent the onset of melanomas, and slow the progression of tumor cells in patients who already suffer from the disease.

Melanomas could be a thing of the past thanks to a new vaccine. The University of Tel Aviv has developed two experimental drugs that can stimulate the immune system to attack melanomas. The compounds are found within a nanoparticle and act as a preventive vaccine to prevent cancer from being generated, according to the study published in Nature Nanotechnology.

Although treatments to combat any type of cancer have advanced incredibly in recent years, they are still very aggressive solutions for patients. The study leader, Satchi-Fainaro, believes that all possible options for vaccines have not yet been exploited. They are used to fight all kinds of viral diseases, but they are not used just to fight cancer, according to the New Atlas magazine.

A medicine composed of nanoparticles

The drugs that have been used in the vaccine are anti-PD1 and anti-OX40 antibodies. The two molecules are designed to stimulate the human body itself and that our immune system is the one that attacks tumor cells when they begin to form. The nanoparticle in which the antibodies are found is a biodegradable “shell” made of polymers that releases experimental drugs once it is inside the human body.

Vaccines have been tested in two types of mice. The first were mice that had already developed a melanoma and treatment significantly delayed the progression of the disease. The second mice had not yet developed any melanoma and the vaccine managed to prevent the onset of cancer, even after being injected with cancer cells.

Now, the project is collecting human metastatic cells to adapt the vaccine to our immune system. Although the results have been very positive, the vaccine would not be ready to be used in humans for about 10 years.

Although we cannot benefit from the vaccine at the moment, the study has again proven that the concept of anticancer vaccines is an unexplored territory that is worth investigating.
