A Purdue-affiliated startup has created a platform aimed at treating relapse patients for cancers and other diseases by taking a holistic approach of not only seeking to impede the main cause but also to stop other elements that help that disease thrive. KinaRX LLC has developed a platform that makes complex drug molecules rapidly using bioinformatics, multi-component compound synthesis and the understanding of disease biology.

Where did the Technology Originate from?

The platform was created by the lab of Herman O. Sintim, the Drug Discovery Professor of Chemistry in Purdue’s Department of Chemistry. Professor Sintim notes “Diseases are complex. Until you tackle the main drivers and the underlying issues, it’s going to be difficult to cure diseases. So what KinaRx is doing is developing drugs that hit not only the main disease drivers but also the collaborative players that allow the disease to progress.”

What is KinaRX?

It is a startup venture and spin-off of Purdue. It was founded by Sintim as well as chief scientific officer, along with M. Javad Aman, Rena Lapidus, Ashkan Emadi, Frederick Holtsberg, and Joe O’Neill. The firm is based in Rockville MD and was founded in 2017

How did it Secure the Technology from Purdue?

The company secured the license from the Purdue Office of Technology Commercialization, which operates one of the most comprehensive technology transfer programs in the U.S. KinaRx has licensed through the Purdue Research Foundation Office of Technology Commercialization a series of drug compounds that have shown promise in treating patients who have a recurrence of acute myeloid leukemia (AML), an aggressive blood cancer that is one of the most lethal cancers.


AML, an aggressive blood cancer that is one of the most lethal cancers. About 19,520 news cases are diagnosed a year, and about 10,670 people a year die from it, according to the American Cancer Society.

About 30 percent of AML patients have a mutation caused by a kinase called FLT3, which makes leukemia more aggressive. Although a few FLT3 inhibitors have already been approved in the clinic, patients can relapse due to mutations in the FLT3 protein, which cause drug resistance. Researchers in Sintim’s lab has developed a series of new compounds that inhibit mutant FLT3 kinases. In mice models of drug-resistant AML, the KinaRx compounds performed better than gilteritinib and quizartinib (two FLT3 inhibitors that have been approved or undergone clinical trials). It is anticipated that these compounds will have superior performance against AML compared with the standard treatment.

Other Treatments such as Lung Cancer

KinaRx also is working on a treatment for a form of lung cancer with mutation in the RET kinase, which is found in about 2 percent of patients. In addition to FLT3 and RET, KinaRx is also developing therapeutics based on the inhibition of many other kinases, such as ROCK1 and 2, MNK2, Cyclin-dependent kinases, EphA2, TrkA, B or C, CLK1-4, Haspin, TOPK/PBK, p70S6K, CSF1R, and many other kinase targets. KinaRx is also looking at other cancers and other diseases caused by inflammation.

Sintim believes that kinases, which KinaRx derives its name from, are important to curing diseases. There are more than 500 kinases in a cell, and kinases are the second most important drug target behind G-protein-coupled receptors or GPCRs.

“Kinases basically signal so many processes in a cell. So they are drug targets for many diseases,” Sintim said. “We have developed a technology that is so powerful that we will be able to target many diseases associated with kinases.”

KinaRx has applied for grants and is looking for investors as it continues to develop the platform.
