NASA touts research in ‘space labs’ to fight cancer

Researchers will be able to make a drug that can be administered by injection in a doctor’s office instead of through long and painful chemotherapy treatments.

Experiments in the weightless environment of space have led to “crazy progress” in the fight against cancer,

NASA officials said at a recent event highlighting an important and personal initiative of U.S. President Joe Biden.

Frank Rubio, an astronaut, physician, and former military helicopter pilot, conducted cancer research during his recent mission to the International Space Station (ISS), orbiting some 400km above the earth’s surface.

Cells there age more rapidly, speeding up research, and their structures are also described as “purer”.

“They all don’t clump together (as they do) on the earth because of gravity,”

NASA chief Bill Nelson told AFP in an interview. “They are suspended in space,” enabling better analysis of their molecular structure.

Research conducted in space can help make cancer drugs more effective, Mr. Nelson added.

Pharmaceutical giant Merck has conducted research on the ISS with Keytruda, an anticancer drug that patients now receive intravenously. Its key ingredient is difficult to transform into a liquid. One solution is crystallisation, a process often used in drug manufacturing.

In 2017, Merck conducted experiments to see if the crystals would form more rapidly in space than on the earth.

Mr. Nelson used two pictures to demonstrate the difference. The first showed a blurry, transparent spot. But on the second, a large number of clear grey spots had emerged.

That photo showed that smaller, more uniform crystals were forming in space — and “forming better,” Mr. Nelson said.

Thanks to such research, researchers will be able to make a drug that can be administered by injection in a doctor’s office instead of through long and painful chemotherapy treatments, he added.

Merck identified techniques that can help it imitate the effects of these crystals on the earth as it works to develop a drug that can be stored at room temperature.

Still, it can take years between research in space and the wide availability of a drug developed there.

Cancer research in space began more than 40 years ago but has become “revolutionary” in recent years, said Mr. Nelson, a former Democratic senator who travelled into space himself in 1986.

“We use the languages of space to tell the limits of cancer,” added W. Kimryn Rathmell, director of the National Cancer Institute, a federally funded research body.

Mr. Biden launched a “Cancer Moonshot” initiative in 2016, when he was then vice president, echoing a speech by John F. Kennedy some 60 years earlier outlining the bold goal of sending an American to the moon.

The goal of the “Moonshot” is to halve the death rate from cancer over the next quarter century, saving four million lives, according to the White House.
