Medical advances

- BY JIM STAFFORD Jim Stafford writes about Oklahoma innovation and research and developmen­t topics on behalf of the Oklahoma Center for the Advancemen­t of Science & Technology (OCAST).

DRIK, which provides preclinica­l toxicology testing for researcher­s worldwide, is generating revenue and achieving the goal of any startup — it is bringing dollars from out of state.

Kumar Sripathira­than, Ph.D., placed a slide under a microscope lens in the laboratory of Oklahoma City’s DRIK Safety Testing and an image instantly appeared on an adjacent computer screen.

It looked vaguely like a satellite image of Spain to me.

Dr. Kumar, as I call him, pointed me in a different direction.

“This is a tumor,” he said. I squinted.

DRIK is a contract research organizati­on that provides preclinica­l toxicology testing for researcher­s worldwide wanting to discover the effects of drugs or chemicals on the body.

“We help pharmaceut­ical companies in the preclinica­l discovery efforts,” Dr. Kumar said. “We also conduct toxicology and efficacy testing for pharmaceut­ical drugs, chemical, agri-chemical businesses and also the cosmetic industries.”

Toxicology testing is a key step in drug developmen­t. Safety and efficacy are important because most drugs fail during developmen­t. That’s when researcher­s are most likely to discover new therapeuti­cs aren’t as effective as originally indicated or they fail safety testing.

DRIK and its staff of three use what is called 3-D modeling of live tissue samples to study the effects of drugs on tissue. It can be tissue from the heart or brain or even a tumor.

“The Food and Drug Administra­tion requires these studies be conducted to make sure humans aren’t in harm’s way,” Dr. Kumar said. “We can keep these 3-D tissue slices alive for 60 days or more, which means the drug companies can do the testing with their drugs for more than 60 days at a very low dose. The models provide very high value in terms of the data that it produces and to de-risk developmen­t.”

DRIK, which has investment funding from i2E Inc.’s StartOK Fund, is generating revenue and achieving the goal of any Oklahoma startup — it is bringing dollars into Oklahoma from out of state.

Dr. Kumar recently launched a second company that complement­s DRIK’s safety testing services. DEHA is a drug developmen­t company that is focused on providing a treatment for what are known as brain edemas caused by large strokes and concussion­s.

Athletes and soldiers most frequently suffer the type of injuries that cause brain edemas.

“Brain edema is accumulati­on of fluid on the brain, especially water on the brain,” Dr. Kumar said. “There are not many drugs available, and the approach of those that are, are not specific for solving brain edemas.”

DEHA is developing a small molecule therapy that would relieve the fluid accumulati­on in brain edemas at a much faster pace than say, diuretics. Time is a critical factor in treating edemas.

“In a large stroke there is a lot of fluid accumulati­ng in the brain, and cranial pressure accumulate­s over a short time period of about 24 hours,” he said. “A surgeon has to intervene to remove the brain edema. If nothing is done, then it is life-threatenin­g.”

That is the challenge that DEHA is working to achieve. DEHA has a literal meaning of “body,” Dr. Kumar said.

Dr. Kumar and his wife and DRIK co-founder, Vanmathy Vasudevan, decided to launch a second company after investigat­ing the number of what he calls “neglected diseases” that the drug developmen­t world ignores.

“It’s interestin­g to note that humankind has detected about 6,500 diseases,” he said. “Of those 6,500 diseases, FDAapprove­d medication is only available for onethird of them. We would like to develop more compounds that address as many of these diseases as possible.”

For the founders of DRIK and DEHA, the goal of each company is to make an impact internatio­nally with both their drug testing and drug developmen­t initiative­s.

But DEHA is still in the early stages, Dr. Kumar cautioned. He is seeking patent protection for the intellectu­al property the company is developing.

“We would like people to know that the drug developmen­t pipeline is a very long and arduous, costly process,” he said. “So, it will take time for drug developmen­t to move forward.”

That’s the way the drug developmen­t world works. After a new therapeuti­c is developed, it has to be tested over and over to ensure it is safe and effective.

DRIK and DEHA have it all covered.

“We want to take slow and steady steps,” Dr. Kumar said.
