Houston-based Vax-Immune Diagnostics has commenced on a new multicenter clinical trial to roll out a specific lab test as a part of its LabReady product.

The 12-week study will analyze results from Group B Streptococcus lab tests in expecting mothers. Currently, 16 to 20 percent of pregnant women are affected by GBS, according to a news release, which will then infect their newborn through the childbirth process.

Vax-Immune's product, LabReady, enhances the transportation process of lab samples and aims to improve the quality of results in patients. The company is expected to report data from the trial this summer.

"Currently samples are not regulated through transport from the patient to the lab often causing inaccurate test results. And inaccurate test results can cause significant problems since medical decisions are based on these results," Dr. Leonard E. Weisman, president and chief technology officer at Vax-Immune Diagnostics, says in the release.

"Our device, LabReady collects, protects, processes, and prepares the sample from the patient through transport, so when it arrives at the laboratory, infection can easily and accurately be diagnosed."

This study is planned to randomize approximately 300 patients from 35 to 37 weeks of pregnancy, according to the release. GBS is the most common cause of infections such as sepsis, meningitis, and pneumonia among newborns. The Centers for Disease Control and Prevention, among other organizations, have launched efforts for screenings and tests to reduce cases of neonatal GBS disease.

Vax-Immune was a member of the Texas Medical Center's 2018 TMCx Medical Device cohort and pitched at the 7th TMCx Demo Day. The company is a JLABS @ TMC resident.

5 Texas companies present the future of health care at TMCx's Demo Day

Homegrown heroes

After four months of product design, networking with medical professionals, pitching to investors, and more, 23 startup leaders had just a few minutes to show the medical community what they've achieved and where they're going next.

Over 700 attendees made it to TMCx's 7th Demo Day or tuned in online to see the results of Houston's award-winning medical devices accelerator program.

"It's really the draw of the experts within our 23 hospitals and clinics that really makes us quite special in our ecosystem compared to the East and West coasts," Texas Medical Center CEO Bill McKeon says. "We're proud to call ourselves the Third Coast of the life sciences."

The cohort, which is the most international to date with nine international companies, has already raised $73 million and confirmed 108 signed agreements for medical professional partnerships.

"The thing that cracks me up from time to time," says Erik Halvorsen, director of the TMC Innovation Institute, "is when you see these talks that say, 'what can the Houston ecosystem learn from Silicon Valley.' Well you know what, I think we're ready to flip that, and say, 'here's what can Silicon Valley learn from us here in Houston — what we've built and where we're headed.'"

From a wearable device that reduces back pain to a new technology that reduces suicidal thoughts, the cohort's presentations didn't disappoint. While all the cohorts made business connections to Houston in the months they were at TMCx, five of the 23 companies are based in Texas. Here are the companies with Lone Star State roots.

Articulate Labs

Herbie Kirn, co-founder and chief scientific officer of Articulate Labs, lost his leg from the knee down in a motorcycle accident and quickly wore through his other knee's cartilage. If he didn't do sufficient rehabilitation and physical therapy, he would lose function of that leg too.

Over 14 million people in the United States individuals suffer from chronic knee problems; however, whether it be due to time or cost, over 70 percent of those affected cannot attend the prescribed physical therapy.

Dallas-based Articulate Labs has a solution. The KneeStim device allows the patient to turn daily activities into rehabilitation exercises.

The company has raised a little over $500,000 already, but looks to raise $1 million with its next round of funding. Articulate Labs is also looking for more scientific and strategic partners.

Intelligent Implants

Chronic lower back pain can result in a need for spinal fusion surgery — and 40 percent of those surgeries fail, says Juan Pardo, co-founder of Intelligent Implants, which has an office in Houston. Pardo and his team have come up with an implant that tracks post-op healing and introduces electronic stimulation wirelessly.

The device is the same size and shape as the spacer that surgeons currently use, but contains a technology that can deliver electronic stimulation therapy and monitor progress without needing batteries. The doctor is able to adjust treatment remotely, and the device can heal the patient 50 percent faster than the standard care.

Intelligent Implants was announced as the first in-residence company at the Center for Device Innovation by Johnson and Johnson and also launched its large animal studies. The company has a goal to raise $1.6 million, and has already secured $900,000 — $250,000 of which came from the new TMC Venture Fund.

Swarna Balasubramaniam watched helplessly as her mom slowly healed from gastrointestinal surgery. She couldn't eat and had trouble sleeping — both of which hindered her ability to heal quickly.

Balasubramaniam, founder of Houston-based Noleus Technologies, created a solution that reduces swelling in the bowels after operation. The disposable device is inserted into the abdomen at the time of surgery, and folds up like a fan to be removed without another surgery.

The invention is attractive to all parties involved. Patients are able to heal quicker, and surgeons are able to provide better care for their patients. Additionally, hospitals, which have bundled reimbursement for surgeries like this, are able to shorten the recovery time for patients thus reducing the costs spent on caring for the patient. Balasubramaniam says she estimates the device saving hospitals $4,000 per patient.

Over 70 percent of care decisions come from lab results, but more than 20 percent of microbiology lab tests are inaccurate due to problems in transport from the patient to the lab. Leonard Weisman, founder and chief technology officer of Houston-based Vax-Immune Diagnostics, invented Lab Ready — a tool for protecting the quality of the sample for testing.

The device is easy for patients to use at home and send to the lab directly, and the device is likewise easy to use by lab technicians.

Lab Ready is prepared to launch in 2019, immediately following FDA approval. Vax-Immune is on track to meet its funding goal of $5 million in the first quarter of 2019.

VenoStent

Patients with kidney disease or diabetes have four chances to get an external stent successfully inserted into their arms for dialysis treatment, and the current standard of care results in a failure in half of these access sites, says Tim Biore, founder of Houston-based VenoStent.

It was Biore's vision to create a device that allows a successful stent implementation on the first try. VenoStent's SelfWrap is made from a shape-memory polymer that uses body heat to mold the stent into the vein-artery junction.

One in eight people suffer from kidney disease, and Biore says SelfWrap would save Medicare upwards of $200 million annually, while improving the success rate by 20 to 30 percent.

VenoStent has seven signed agreements from partners as a result of the accelerator program. The company is seeking $2.4 million to continue manufacturing as they await FDA clearance — expected in early 2022.

Rice University team develops eco-friendly method to destroy 'forever chemicals' in water

clean water research

Rice University researchers have teamed up with South Korean scientists to develop the first eco-friendly technology that captures and destroys toxic “forever chemicals,” or PFAS, in water.

PFAS have been linked to immune system disruption, certain cancers, liver damage and reproductive disorders. They can be found in water, soil and air, as well as in products like Teflon pans, waterproof clothing and food packaging. They do not degrade easily and are difficult to remove.

Thus far, PFAS cleanup methods have relied on adsorption, in which molecules cling to materials like activated carbon or ion-exchange resins. But these methods tend to have limited capacity, low efficiency, slow performance and can create additional waste.

The Rice-led study, published in the journal Advanced Materials, centered on a layered double hydroxide (LDH) material made from copper and aluminum that could rapidly capture PFAS and be used to destroy the chemicals.

The study was led by Rice professor Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong. It was conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology, and Keon-Ham Kim, professor at Pukyung National University, who first discovered the LDH material.

The team evaluated the LDH material in river water, tap water and wastewater. And, according to Rice, that material’s unique copper-aluminum layers and charge imbalances created an ideal binding environment to capture PFAS molecules.

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” Chung, lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute, said in a news release. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

Next, Chung, along with Rice professors Pedro Alvarez and James Tour, worked to develop an eco-friendly, sustainable method of thermally decomposing the PFAS captured on the LDH material. They heated saturated material with calcium carbonate, which eliminated more than half of the trapped PFAS without releasing toxic by-products.

The team believes the study’s results could potentially have large-scale applications in industrial cleanups and municipal water treatments.

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong added in the news release. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”

Axiom Space announces new CEO amid strategic leadership change

new leader

Six months after promoting Tejpaul Bhatia from chief revenue officer to CEO, commercial space infrastructure and human spaceflight services provider Axiom Space has replaced him.

On Oct. 15, Houston-based Axiom announced Jonathan Cirtain has succeeded Bhatia as CEO. Bhatia joined Axiom in 2021. Cirtain remains the company’s president, a role he assumed in June, according to his LinkedIn profile.

In a news release, Axiom said Cirtain’s appointment as CEO is a “strategic leadership change” aimed at advancing the company’s development of space infrastructure.

Axiom hired Cirtain as president in June, according to his LinkedIn profile. The company didn’t publicly announce that move.

Kam Ghaffarian, co-founder and executive chairman of Axiom, said Cirtain’s “proven track record of leadership and commitment to excellence align perfectly with our mission of building era-defining space infrastructure that will drive exploration and fuel the global space economy.”

Aside from praising Cirtain, Ghaffarian expressed his “sincere gratitude” for Bhatia’s work at Axiom, including his leadership as CEO during “a significant transition period.”

Bhatia was promoted to CEO in April after helping Axiom gain more than $1 billion in contracts, Space News reported. He succeeded Ghaffarian as CEO. Axiom didn’t indicate whether Bhatia quit or was terminated.

Cirtain, an astrophysicist, was a senior executive at BWX Technologies, a supplier of nuclear components and fuel, for eight years before joining Axiom. Earlier, Cirtain spent nearly nine years in various roles at NASA’s Marshall Space Flight Center in Huntsville, Alabama. He previously co-founded a machine learning company specializing in Earth observation.

“Axiom Space is pioneering the commercialization of low-Earth orbit infrastructure while accelerating advancements in human spaceflight technologies,” Cirtain said. “I look forward to continuing our team’s important work of driving innovation to support expanded access to space and off-planet capabilities that will underpin the future of space exploration.”

Among other projects, Axiom is developing the world’s first commercial space station, creating next-generation spacesuits for astronauts and sending astronauts on low-Earth orbit missions.
