Drug Manufacturing Process for PA-824, am Anti-TB DrugINNOVATION RESOURCES

Breakthrough:
A faster and more efficient drug manufacturing process for the development of new drugs against tuberculosis.

The Story:
When the non-profit Global Alliance for TB Drug Development (TB Alliance) needed to solve some drug manufacturing problems it turned to open innovation for the answers.

Tuberculosis is an infectious bacterial disease that is still a major global health emergency. It is the leading cause of bacterial death as every 20 seconds someone dies from the disease.

The first antibiotics against the contagious condition appeared in the 1940s, but since then many drug resistant strains of the TB bacterium have emerged. The Global Alliance for TB Drug Development is dedicated to speeding up the discovery and development of new TB drugs. And open innovation is helping.

Open Innovation Provides Answers

In the spring of 2007 the organization turned to open innovation to find new methods for accelerating and simplifying the manufacturing process for a promising new drug candidate called PA-824. The challenge was posted on InnoCentive and 27 proposals were received by TB Alliance.

Advanced Drug Candidate

kana_sureshan.jpgPA-824 is one of TB Alliance’s most advanced drug candidates which differs from most TB drugs in that it targets the bacterium’s slow-growth and rapid growth phases. Antibiotic drug treatment for TB is lengthy and arduous with up to four drugs being administered for six months. Many people don’t finish the course which contributes to increased drug resistance. And some of those drugs are more than 40 years old. PA-824 could drastically reduce the amount of time it takes to cure TB.

TB Alliance scientists sifted through the proposals and selected two winners, one based in China and the other in India. They received a $20, 000 award for their problem solving skills.

The two winning solvers proposed a solution by which the route to synthesize PA-824 is reduced from five steps down to just three.

"It is rewarding and exciting to apply my expertise to create a method that will help accelerate the drug discovery process for tuberculosis, a disease that affects millions of people, ” said solver Dr. Kana M Sureshan from the Institute of Life Sciences in Hyderabad, India. “I look forward to seeing this implemented and to continue my work and interest in the fields of medicinal chemistry and chemical biology to advance treatments and processes being used to fight various diseases."

And there appears to be an additional benefit to their process in that it may eliminate a reactant that’s known to irritate skin and eyes.

Open Innovation is a No-Brainer

There is an urgent need to shorten the time it takes to develop new drugs against TB as currently they are not coming out of the lab and into the world quick enough.

Marijuana smoking 'permanently lowers IQ'
Teenagers who regularly smoke cannabis are putting themselves at risk of permanently damaging their intelligence, according to a landmark study.
Researchers found persistent users of the drug, who started smoking it at school, had lower IQ scores as adults.
They were also significantly more likely to have attention and memory problems in later life, than their peers who abstained.
Furthermore, those who started as teenagers and used it heavily, but quit as adults, did not regain their full mental powers, found academics at King’s College London and Duke University in the US

Parents, talk to your kids about marijuana. It is an extremely harmful, illegal drug.
Dec 16, 2013 - Research released Monday in the journal Schizophrenia Bulletin showed the brains of young heavy marijuana users were altered in sub-cortical regions — primitive structures that are part of the memory and reasoning circuits. And young people with such alterations performed worse on memory tests than non-using controls, despite the fact that the heavy users had not indulged for more than two years, on average, before the testing.
