Cuba Has a Lung Cancer Vaccine—And America Wants It
Researchers will bring the vaccine stateside and track it for the FDA so it can be manufactured and sold in the US.
CUBA HAS FOR several years had a promising therapeutic vaccine against lung cancer. The 55-year trade embargo led by the US made sure that Cuba was mostly where it stayed. Until—maybe—now.
“The chance to evaluate a vaccine like this is a very exciting prospect,” says Candace Johnson, CEO of Roswell Park. She’s excited, most likely, because research on the vaccine so far shows that it has low toxicity, and it’s relatively cheap to produce and store. The Center for Molecular Immunology will give Roswell Park all of the documentation (how it’s produced, toxicity data, results from past trials) for an FDA drug application; Johnson says she hopes to get approval for testing Cimavax within six to eight months, and to start clinical trials in a year.
How did Cuba end up with a cutting edge immuno-oncology drug? Though the country is justly famous for cigars, rum, and baseball, it also has some of the best and most inventive biotech and medical research in the world. That’s especially notable for a country where the average worker earns $20 a month. Cuba spends a fraction of the money the US does on healthcare per individual; yet the average Cuban has a life expectancy on par with the average American. “They’ve had to do more with less,” says Johnson, “so they’ve had to be even more innovative with how they approach things. For over 40 years, they have had a preeminent immunology community.”
Despite decades of economic sanctions, Fidel and Raul Castro made biotechnology and medical research, particularly preventative medicine, a priority. After the 1981 dengue fever outbreak struck nearly 350,000 Cubans, the government established the Biological Front, an effort to focus research efforts by various agencies toward specific goals. Its first major accomplishment was the successful (and unexpected) production of interferon, a protein that plays a role in human immune response. Since then, Cuban immunologists made several other vaccination breakthroughs, including their own vaccines for meningitis B and hepatitis B, and monoclonal antibodies for kidney transplants.
The thing about making such great cigars is, smoking is really, really bad for you. Lung cancer is the fourth-leading cause of the death in Cuba. Medical researchers at the Center for Molecular Immunology worked on Cimavax for 25 years before the Ministry of Health made it available to the public—for free—in 2011. Each shot costs the government about $1. A Phase II trial from 2008 showed lung cancer patients who received the vaccine lived an average of four to six months longer than those who didn’t. That prompted Japan and some European countries to initiate Cimavax clinical trials as well.
