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 geothermal unicorn Fervo officially files for IPO

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

New UT Austin med center, anchored by MD Anderson, gets $1 billion gift

Future of Health

A donation announced Tuesday, April 21, breaks a major record at the University of Texas at Austin. Michael and Susan Dell are now UT Austin's first supporters to give $1 billion. In response, the university will create the UT Dell Campus for Advanced Research and the UT Dell Medical Center to "advance human health," per a press release.

The release also records "significant support" for undergraduate scholarships, student housing, and the Texas Advanced Computing Center for supercomputing research.

Both the new research campus and the UT Dell Medical Center will integrate advanced computing into their research and practices. At the medical center, the university hopes that will lead to "earlier detection, more precise and personalized care, and better health outcomes." The University of Texas MD Anderson Cancer Center will also be integrated into the new medical center.

That comes with a numeric goal measured in 10s: raise $10 billion and rank among the top 10 medical centers in the U.S., both in the next decade.

In the shorter term, the university will break ground on the medical center with architecture firm Skidmore, Owings & Merrill (SOM) "later this year."

“UT Austin, where Dell Technologies was founded from a dorm room, has always been a place where bold ideas become real-world impact,” said Michael and Susan Dell in a joint statement.

They continued, “What makes this moment so meaningful is the opportunity to build something that brings every part of the journey together — from how students learn, to how discoveries are made, to how care reaches families. By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond.”

This is the second major gift this year for the planned multibillion-dollar medical center. In January, Tench Coxe, a former venture capitalist who’s a major shareholder in chipmaking giant Nvidia, and Simone Coxe, co-founder and former CEO of the Blanc & Otus PR firm, contributed $100 million$100 million.

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.
