A Houston-born company is enrolling patients in a study to test the efficacy of nerve stimulation to improve outcomes for stroke survivors.

Dr. Kirt Gill and Joe Upchurch founded NeuraStasis in 2021 as part of the TMC Biodesign fellowship program.

“The idea for the company manifested during that year because both Joe and I had experiences with stroke survivors in our own lives,” Gill tells InnovationMap. It began for Gill when his former college roommate had a stroke in his twenties.

“It’s a very unpredictable, sudden disease with ramifications not just for my best friend but for everyone in his life. I saw what it did to his family and caregivers and it's one of those things that doesn't have as many solutions for people to continue recovery and to prevent damage and that's an area that I wanted to focus myself on in my career,” Gill explains.

Gill and Upchurch arrived at the trigeminal and vagus nerves as a potential key to helping stroke patients. Gill says that there is a growing amount of academic literature that talks about the efficacy of stimulating those nerves. The co-founders met Dr. Sean Savitz, the director of the UTHealth Institute for Stroke and Cerebrovascular Diseases, during their fellowship. He is now their principal investigator for their clinical feasibility study, located at his facility.

The treatment is targeted for patients who have suffered an ischemic stroke, meaning that it’s caused by a blockage of blood flow to the brain.

“Rehabilitation after a stroke is intended to help the brain develop new networks to compensate for permanently damaged areas,” Gill says. “But the recovery process typically slows to essentially a standstill or plateau by three to six months after that stroke. The result is that the majority of stroke survivors, around 7.6 million in the US alone, live with a form of disability that prevents complete independence afterwards.”

NeuraStasis’ technology is intended to help patients who are past that window. They accomplish that with a non-invasive brain-stimulation device that targets the trigeminal and vagus nerves.

“Think of it kind of like a wearable headset that enables stimulation to be delivered, paired to survivors going through rehabilitation action. So the goal here is to help reinforce and rewire networks as they're performing specific tasks that they're looking to improve upon,” Gill explains.

The study, which hopes to enroll around 25 subjects, is intended to help people with residual arm and hand deficits six months or more after their ischemic stroke. The patients enrolled will receive nerve stimulation three times a week for six weeks. It’s in this window that Gill says he hopes to see meaningful improvement in patients’ upper extremity deficits.

Though NeuraStasis currently boasts just its two co-founders as full-time employees, the company is seeing healthy growth. It was selected for a $1.1 million award from the National Institutes of Health through its Blueprint MedTech program. The award was funded by the National Institute of Neurological Disorders and Stroke. The funding furthers NeuraStasis’ work for two years, and supports product development for work on acute stroke and for another product that will aid in emergency situations.

Gill says that he believes “Houston has been tailor-made for medical healthcare-focused innovation.”

NeuraStasis, he continues, has benefited greatly from its advisors and mentors from throughout the TMC, as well as the engineering talent from Rice, University of Houston and Texas A&M. And the entrepreneur says that he hopes that Houston will benefit as much from NeuraStasis’ technology as the company has from its hometown.

“I know that there are people within the community that could benefit from our device,” he says.

4 Houston startups selected for preeminent medtech accelerator

ready to grow

Four Houston startups have been selected for the 2023 cohort of the MedTech Innovator’s four-month accelerator program.

Los Angeles-based MedTech Innovator, which bills itself as the world’s largest medtech accelerator, will award $800,000 in funding to winners of its competitions throughout the 2023 program. The grand prize is $350,000.

Almost 1,200 startups applied to participate in this year’s accelerator. From that group, MedTech Innovator, its corporate partners, and more than 400 judges picked nearly 200 candidates for in-person pitching and partnering events. Sixty-one startups ultimately were chosen for the 2023 cohort, which kicks off June 14 and 15.

Forty-two of the 61 startups will participate in MedTech Innovator’s corporate mentorship program, and five companies will join a plastic surgery accelerator in conjunction with the American Society for Plastic Surgeons.

MedTech Innovator says more than 500 startups have completed its accelerator program and have secured $6.8 billion in follow-on funding.

“We are proud of our stellar track record of identifying and perfecting the most innovative medtech startups in the world,” Paul Grand, CEO and founder of MedTech Innovator, says in a news release.

The four Houston companies selected for the MedTech Accelerator’s 2023 cohort are:

  • Ankr. The startup (whose name is pronounced “anchor”) provides a caregiving platform for cancer patients in the U.S. As of 2022, there were an estimated 18.1 million cancer survivors across the country. The company won The Ion’s Houston Startup Showcase in 2021.
  • NeuraStasis. The startup is developing an electrical stimulation device to delay the effects of acute ischemic stroke. This type of stroke happens when blood flow to the brain decreases. Acute ischemic stroke affects about 700,000 people in the U.S. each year. The company was selected for last year’s cohort of the UCSF Rosenman Institute’s Rosenman Innovators program.
  • Nininger Medical. The startup is working on a device for minimally invasive replacement of the tricuspid valve. Today, an estimated 1.6 million Americans experience tricuspid regurgitation. This type of heart disease occurs when the tricuspid valve’s flaps don’t close correctly. In 2021, the company received a $256,000 National Science Foundation grant.
  • Prana Thoracic. The startup is developing a tool for minimally invasive removal of lung tissue in lung cancer patients. In March, the company announced $3 million in series A funding.

Last year, three Houston companies were selected for the program. The startups — Ad Vital, Corveus Medical, and CorInnova.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.

NASA unveils Artemis III astronauts at Johnson Space Center in Houston

To the moon

NASA on Tuesday, June 9, revealed the crew for its Artemis III mission, the next step in the space agency's plan to eventually land astronauts on the moon.

The announcement came two months after Artemis II's record-breaking trip around the moon that surpassed the distance record of Apollo 13.

NASA's Randy Bresnik, Frank Rubio, Andre Douglas and the European Space Agency's Luca Parmitano won't fly to the moon or land on the surface. Instead, they’ll orbit Earth while practicing docking their Orion capsule with two lunar landers.

“To the Artemis III crew, we wish you Godspeed on the journey ahead,” said NASA administrator Jared Isaacman.

Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin are racing to deliver the lunar landers. The two-week demo is targeted for 2027. Blue Origin suffered a recent setback when its massive rocket exploded during an engine-firing test on the launch pad in Florida, shaking nearby homes and illuminating the sky with an orange fireball.

NASA's Jeremy Parsons said the setback is a learning opportunity and that the space agency is confident Blue Origin's rocket will be ready in time.

NASA's Artemis program aims to return astronauts to the moon's surface for the first time since the 1970s. A recent revamp of the program announced by Isaacman aims to fast-track it similarly to the Apollo era, adding the upcoming spaceflight around Earth before eyeing a lunar landing in 2028.

“We are certainly humbled as a crew to be able to be your crew that executes this Artemis III mission in space,” said Bresnik, Artemis III commander.

Added Douglas, mission specialist: “My brain — it is going a mile a minute right now. But my heart, it is so warm. It is so full."

In May, NASA awarded hundreds of millions of dollars in contracts to four companies, including Blue Origin, to build landers, rovers and drones for a future moon base. Isaacman said the goal of the moon base is to lay the foundation for a Mars expedition.
