Houston-based Spark Biomedical has created a revolutionary wearable device that provides unprecedented levels of opioid withdrawal relief.

The device known as the Sparrow Therapy System is worn over the ear for five to seven days and sends mild electrical signals to trigger cranial nerves that sit near the skin's surface.

Once activated, the nerves release endorphins that the body has stopped producing on its own during opioid use. The endorphins satisfy the opioid receptors and in turn reduce or prevent the intense symptoms that often come along with opioid withdrawal. According to Spark BioMed CEO Daniel Powell, the technology also helps patients better control their "flight or fight mechanisms," allowing them to make clearer, more logical decisions as they come off of the drug.

"If you ask 100 people who've gone through opioid withdrawal, I would bet 99 of them will tell you they thought they were going to die," Powell says. "Giving them the ability to manage that is huge. It's the first step towards addiction recovery. It's not solving the addiction, but it is an absolute barrier to move forward."

The product was approved by the FDA in January of 2020, after clinical trials showed that the Sparrow could meaningfully reduce withdrawal symptoms in the first hour of use. According to Powell, roughly a third of patients in the trial were completely out of withdrawal and patients' Clinical Opioid Withdrawal Scales scores reduced by more than 53 percent across the board.

Spark, which won Venture Houston's inaugural pitch competition earlier this year, partnered with Houston-based Velentium (which also happened to grow 93 percent last year after partnering with General Motors on Project V) to bring the product from concept to commercial physician prescribed product. "We needed a more sophisticated design house to help us finish it," Powell says.

The up-and-comers were connected through one of Spark's investors. Powell, in a previous career, had also sold a neurostimulator that Velentium CTO Randy Armstrong had invented.

"You're seeing more and more Houston centric medical innovation than we've ever seen before," says Velentium CEO Dan Purvis. "And the cool thing about that is there ends up being a camaraderie amongst entrepreneurs, medical researchers and scientists."

And though the release of Sparrow marks a huge milestone, neither Spark of Velentium are stopping there. Moving forward, Spark aims to conduct a massive study on how a similar technology, dubbed the Roo, can aid infants born to opioid-dependent mothers wean from the drug.

The company also aims to create a next generation Sparrow with the help of Velentium, and will look at long-term uses of the product. Powell says that Spark will look to determine if the product can prevent relapses and help to cure addiction when worn daily or regularly.

"Our big, crazy, ambitious goal is can we actually help people recover from addiction," Powell says. "We're really not addressing psychology, that's going to be in cognitive behavioral therapy. But if we can remove the neurological results of drug use, we think we can make at least start to stack the deck in the favor of the patient versus having the deck stacked completely against them all the time."
