This is because it takes years for the compounds to reach the ozone layer's home in the stratosphere, 15-50 kilometres (10-30 miles) above the earth.
The drugmakers took them to the FDA anyway, hoping that trends toward survival in diseases that are almost always fatal would be enough to get the compounds on the market.

Together, the compounds affect both appetite or satiety and motivation, or the drive to eat, says Gene-Jack Wang, MD, a senior scientist with Brookhaven National Laboratory in Upton, New York.
The compounds that the added genes produce are generally identical to what the body already produces, and the viruses used to insert the new genes are also widely found in humans.
The compounds in their breath were analysed using a technique called secondary electrospray ionisation mass spectrometry (SESI-MS), which is capable of detecting extremely small elements of the chemicals present in their breath.
The four patents-in-suit claim chemical compounds used to fight insomnia, methods for improving sleep by administering the compounds, and methods of inducing tranquilizing or hypnotic effects from the compounds, according to court documents.
Though Herbert's survival is rare in its length, and it's too soon to know if these drugs are a cure, the compounds are at the very least slowing the progression of this monstrous disease.
The researchers, whose work is published in the journal Science, suggest that the compounds might delay onset of the disease - but only when administered prior to or in the early stages of infection.
Other members of my laboratory will use techniques such as force spectroscopy and single-molecule assays to further investigate the compounds that I screen, providing a more complete picture of the actions of these compounds.
The scientists also believe that unlike with insecticides, where as many as 80% of mosquitoes are no longer killed by the compounds, the insects are unlikely to develop resistance to the fungus as it targets many different genes in the parasite.
"It so happens that this year, the compounds that represent the kind of novel approach to medicine that we want to develop happen to be in phase I or phase II, " says Dennis Burns , the head of global business development at Hoffman-La Roche , Roche's U.S.-based drug division.
