A Houston biotech startup is one step closer to releasing its marquee drug for the global insulin market, which is projected to break the $90 billion threshold by 2029.

rBIO says it recently completed testing of the properties of R-biolin, an insulin drug that’s biologically identical to Novo Nordisk’s Novolin drug. The patent for Novolin about two decades ago. In March 2023, the Dutch drugmaker announced it was slashing the list price of Novolin by 65 percent to $48.20 per vial and $91.09 per FlexPen.

Executives at rBIO are now pursuing a partnership with a contract research organization to manage clinical trials of R-biolin. If those trials go well, R-biolin will seek approval to supply its insulin therapy to diabetes patients around the world.

Washington University in St. Louis is rBIO’s academic partner for the R-biolin project.

The rBIO platform produces insulin at greater yields that traditional manufacturing techniques do. The company is striving to drive down the cost of insulin by 30 percent.

About 38 million Americans have diabetes, with the vast majority being treated for type 2 diabetes, according to the U.S. Centers for Disease Control and Prevention (CDC). Many people with diabetes must take insulin to control their blood sugar levels.

Research company iHealthcareAnalyst predicts the global market for insulin will surpass the $90 billion mark in 2029.

“There has been a lot of talk in the media about reducing the cost of insulin for diabetic patients, but what is often overlooked is that the domestic demand for insulin will soon outpace the supply, leading to a new host of issues,” Cameron Owen, co-founder and CEO of rBIO, says in a news release.

“We’re dedicated to addressing the growing demand for accessible insulin therapies, and … we’re thrilled to announce the viability of our highly scalable manufacturing process.”

Professionals from the University of California San Diego and Johns Hopkins University established rBIO in 2020. The startup moved its headquarters from San Diego to Houston in 2022.

Houston doesn't have too many unicorns — startups valued at $1 billion or more — in its innovation ecosystem, but Solugen, a sustainable chemicals company, is among the elite group. Gaurab Chakrabarti, the CEO and co-founder of the company, joined Houston House by the Greater Houston Partnership, to share his story on the SXSW stage.

“You do make your own luck, but you have to be putting in the work to do it," Chakrabarti says, adding that it's not an easy thing to accomplish. “There are things you can be doing to increase your luck surface area."

He shared several lessons he learned on his founder journey in the discussion. Read more.

Following the failure of Silicon Valley Bank, there's one thing Sandy Guitar can say has changed for Houston innovators: Bank diversification is going to be a must.

“We didn't think we needed one last week, but this week we know we need a resilience plan," she says, explaining that bank diversification is going to be added to "the operational due diligence playbook." Read more.

Founded in San Diego, rBIO recently relocated to Houston and has big plans for settling in the city, says Cameron Owen, the company's co-founder and CEO.

“Companies from California like us and the coastal areas were converging here in Houston and creating this new type of bioeconomy,” he tells InnovationMap.

He shares that Houston wasn't originally on his radar, until it was. A visit turned into a relocation, and it's just the beginning for the biotech startup that's focused on using synthetic biology for pharmaceuticals. Read more.

California-founded biotech startup relocates to join Houston's emerging bioeconomy

new to hou

Cameron Owen had an idea for a synthetic biology application, and he pitched it to a handful of postdoctoral programs. When he received the feedback that he didn't have enough research experience, he decided to launch a startup based in San Diego around his idea. He figured that he'd either get the experience he needed to re-apply, or he'd create a viable company.

After three years of research and development, Owen's path seems to have taken him down the latter of those two options, and he moved his viable company, rBIO, to Houston — a twist he didn't see coming.

“Houston was not on my radar until about a year and a half ago,” Owen says, explaining that he thought of Houston as a leading health care hub, but the coasts still had an edge when it came to what he was doing. “San Diego and the Boston area are the two big biotech and life science hubs.”

But when he visited the Bayou City in December of 2021, he says he saw first hand that something new was happening.

“Companies from California like us and the coastal areas were converging here in Houston and creating this new type of bioeconomy,” he tells InnovationMap.

Owen moved to Houston last year, but rBIO still has an academic partner in Washington University in St. Louis and a clinical research organization it's working with too, so he admits rBIO's local footprint is relatively small — but not for long.

"When we look to want to get into manufacturing, we definitely want to build something here in Houston," he says. "We’re just not to that point as a company."

In terms of the stage rBIO is in now, Owen says the company is coming out of R&D and into clinical studies. He says rBIO has plans to fundraise and is meeting with potential partners that will help his company scale and build out a facility.

With the help of its CRO partner, rBIO has two ongoing clinical projects — with a third coming next month. Owen says right now rBIO is targeting the pharmaceutical industry’s biologics sector — these are drugs our bodies make naturally, like insulin. About 12 percent of the population in the United States has diabetes, which translates to almost 40 million people. The demand for insulin is high, and rBIO has a way to create it — and at 30 percent less cost.

This is just the tip of the iceberg — the world of synthetic biology application is endless.

“Now that we can design and manipulate biology in ways we’ve never been able to before,” Owen says, "we’re really only limited by our own imagination.”

Synthetic biology is a field of science that involves programing biology to create and redesign natural elements. While it sounds like science fiction, Owen compares it to any other type of technology.

“Biology really is a type of software,” he says. “Phones and computers at their core run on 1s and 0s. In biology, it’s kind of the same thing, but instead of two letters, it’s four — A, C, T, and G.”

“The cool thing about biology is the software builds the hardware,” he continues. “You put that code in there and the biology builds in and of itself.”

Owen says the industry of synthetic biology has been rising in popularity for years, but the technology has only recently caught up.

“We’re exploring a brave new world — there’s no doubt about that,” Owen says.

Houston space companies win NASA funding to build Mars exploration robots

mission to mars

Two Houston-area spacetech companies have landed a portion of a $17 million award from NASA to develop robots for exploring the surface of Mars, the agency announced this month.

Houston-based Inuitive Machines and Webster, Texas-based MEI Technologies, which does business as Aegis Aerospace, were among the seven companies selected to receive the funding from NASA's Science Transport and Robotic Innovation for Deployment and Exploration (STRIDE) initiative.

According to the release from NASA, the companies are tasked with creating "innovative mobility systems" that would allow future Mars missions to access more challenging terrain and difficult-to-reach regions of the planet, and to travel farther distances. NASA estimated that the work will begin this fall.

NASA solicited proposals for participants in the STRIDE initiative in January. The seven named companies are the first selected to participate in the program.

The additional five companies to receive STRIDE funding include:

"STRIDE demonstrates NASA’s commitment to strong public-private partnerships, allowing the agency to explore new approaches for Mars surface exploration while identifying key capability gaps and development needs for commercial systems that could operate and traverse realistic Martian environments," NASA shared in the announcement.

Last month, Intuitive Machines was awarded $148.3 million to deliver its Nova-C lander to the moon. The funding was part of $600 million the space agency awarded to three companies as part of its Moon Base Program and was Intuitive Machines' sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program. Astrobotic was also one of the companies to land funding for the Moon Base program, as well as Austin-based Firefly Aerospace.

Around the same time, Firefly Aerospace was awarded a $13 million subcontract from NASA’s Jet Propulsion Laboratory to develop technology for NASA’s SkyFall mission to Mars. The mission aims to deploy three Mars helicopters to "perform science and demonstrate airborne subsurface mapping and resource prospecting on the planet." Read more here.

SpaceX launches Starship test flight with most advanced Starlinks to date

Out in Space

SpaceX’s mammoth Starship rocket blasted off Friday, July 24, on another test flight stretching halfway around the world, this time releasing 20 of the most advanced Starlinks.

Towering 407 feet, Starship soared from the company’s base at the southern tip of Texas. NASA monitored the space-skimming flight, a critical step toward using the Starship as a lunar lander for moon crews.

The hourlong journey ended with a splashdown so soft that the spacecraft remained afloat in the Indian Ocean as the SpaceX webcast drew to a close, drawing cheers from employees back at the launch site.

Elon Musk’s SpaceX had replaced six of the 33 engines on the first-stage booster after they failed to ignite earlier in July, resulting in a last-second launch abort. The previous Starship flight in May also experienced engine trouble, which prevented the booster from making a controlled return.

This time, all of the engines fired at liftoff, but not enough of them lit back up for the booster's return, causing it to descend too fast and slam into the Gulf of Mexico. The spacecraft continued soaring eastward, popping out the Starlinks one by one 124 miles up before reentering.

It was the 13th flight of the world’s biggest and most powerful rocket, and the second this year of the new version dubbed V3. Like the previous demo, neither the booster nor spacecraft was meant to be saved, instead plunging into the sea.

The stainless steel, retro-looking spacecraft hovered upright over the Indian Ocean before lowering into the water, more than 10,000 miles from where the flight began.

It was the best reentry yet, according to SpaceX, with the intact booster floating amid just a few flames. Previous flights ended with the spacecraft engulfed in flames and exploding at splashdown — or rupturing in midair.

“We're really pumped about this,” said SpaceX engineer Kate Tice, calling it “lucky flight 13.”

The Starlinks accomplished all their jobs before reentering over the Indian Ocean.

After being ejected from the Starship’s Pez-like dispenser, the Starlinks managed to communicate via lasers with older Starlink models already in orbit. With more than 10,000 Starlinks currently providing internet, SpaceX boasts the world’s largest satellite constellation.

Six of the newly launched Starlinks carried cameras that photographed Starship’s heat shield at flight's end, beaming back amazingly crisp shots even as the spacecraft bobbed in the ocean. The heat shield was also equipped with sensors to measure the extreme pressure placed on the spacecraft during launch. Most of the heat shield’s thermal tiles were black, but some were deliberately painted white to simulate missing tiles, part of an experiment to test the shield’s robustness.

"We got all the heat shield data we needed and then some!" Musk said on X.

NASA Administrator Jared Isaacman offered congratulations. “Excited for what will be learned from this mission,” Isaacman noted on X.

SpaceX wants to make sure Starship’s heat shield can withstand the heat of entry before trying to return it to the Starbase launch pad near the Texas-Mexico border. The company already has used a pair of giant mechanical arms at the pad to capture a Starship booster. The company plans to do the same with the actual spacecraft, which is designed to be totally reusable.

NASA needs Starship to wrap up testing and reach orbit soon so the Artemis III astronauts — three Americans and one Italian — can practice docking their capsule with it next year.

Starship is also the vehicle with which Musk intends to build a city on Mars. He's already booking tourist trips to Mars, as well as the moon.

The latest test flight was delayed first by the July 16 launch abort, then again July 23 by thick clouds from Tropical Storm Bertha.

University of Houston debuts UH Health, expanding collaborative health care and research efforts

health care hub

The University of Houston has announced its cross-disciplinary academic venture, UH Health.

It will align UH’s efforts in education, research and clinical partnerships to create new opportunities to advance research and innovation, community impact, and education, according to a news release.

“From opening the state’s first college of optometry to developing groundbreaking vaccines, improving the health of all Texans has been a UH priority for decades,” UH President Renu Khator said in the release. “Now, with the launch of UH Health, we are bringing together the full strength of our health enterprise to expand our reach, advance research and transform the future of health for our communities.”

UH is adopting a fully collaborative model, with health professionals from various concentrations to help better understand overall patient care, which includes factors like clinical, behavioral and social factors that can influence health outcomes.

UH Health will also have partnerships with HCA Healthcare, Memorial Hermann Hospital, Baylor College of Medicine, MD Anderson Cancer Center and other Texas Medical Center facilities. In addition, UH Health will work with DHR Health in the Rio Grande Valley to create new opportunities for health care education, workforce development and research in one of Texas' medically underserved regions.

As part of UH Health, UH Health Family Care Center will provide integrated primary care and mental health services to the University and its surrounding communities at affordable prices to serve the Third Ward, East End and South Houston. The Household-Centered Care program will give students opportunities to work directly with community caregivers through patient home visits, while the 3rd Ward Place of Wellness offers health screenings, preventive services, education and other resources designed to support long-term health and well-being, according to UH. The College of Optometry will continue to see children and families via outreach programs and clinics across the community.

UH Health also aims to address shortages in health care professionals, providing a pipeline from the university to the workforce. According to the Texas Hospital Association, 64 percent of hospitals in the state are operating with reduced services and fewer beds due to staff shortages.

“Preparing the next generation of health care leaders is one of the most important investments we can make in the future of our state,” Jonathan McCullers, vice president for health affairs at UH and dean of the Tilman J. Fertitta Family College of Medicine at UH, added in the release. “UH Health is ensuring our graduates are equipped to work effectively in today’s complex healthcare environment.”

Additionally, UH shared it is investing $77 million into a 55,000-square-foot medical research facility aimed at boosting interdisciplinary research and scientific discovery.

“Healthcare is no longer delivered in isolation, and complex health challenges require coordinated solutions,” McCullers added. “UH Health allows us to work across disciplines to tackle health challenges, advance research and improve outcomes for patients and our community.”
