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.

European spacecraft developer expands to Houston with U.S. business, new lab

houston hq

European aerospace manufacturer The Exploration Company has established its first U.S. entity and named Space City as its headquarters.

The company announced earlier this month that it has launched TEC Federal to support U.S. government customers and agencies, and to scale The Exploration Company's engineering operations in the country.

Mark Kirasich serves as president of TEC Federal. Kirasich most recently served as the senior director of human spaceflight at Blue Origin after a nearly 40-year career at NASA.

The Exploration Company is developing the reusable Nyx space vehicle. Nyx is designed to take off from any heavy launcher in the world. It will then dock at space stations, retrieve up to 3,000 kilograms of cargo, splash down and return the cargo to Earth. The company aims to make Nyx fully reusable for up to 10 missions, making it a more affordable and sustainable option for aerospace missions.

The Exploration Company completed a successful drop test of the spacecraft in May in the Mojave Desert. The company says Nyx is slated to perform its first flight demonstration in 2028.

In addition to launching the Houston business, The Exploration Company also opened its new Rapid Innovation Lab near Houston's NASA Johnson Space Center on Space Park Drive.

The Rapid Innovation Lab features a full-scale mockup of the future Nyx crew capsule as well as ongoing development and testing of the Nyx cargo capsule, according to the company.

The Exploration Company says the new lab will allow its engineers, designers, and operators to prototype and test crew interfaces. It will also support partnerships with NASA personnel and astronauts.

“Houston gives us direct access to the people and expertise that have built and operated human spaceflight systems for decades. We’re excited to invest and expand around that— engineers, operators, and astronauts working together and moving quickly towards building a crew capsule.” Hélène Huby, founder and CEO of The Exploration Company, said in a blog post.

According to The Houston Chronicle, The Exploration Company has about 30 employees in the Houston area.

The company was founded in 2021 by Huby, a French rocket scientist, and has raised more than $350 million in venture capital. It operates out of Germany, France, Luxembourg, Spain and Italy, with offices in the U.S. and the United Arab Emirates. It is also developing a reusable, high-thrust rocket engine known as Storm.

Exciting XSpace expansion plans + more top Houston innovation headlines

3. Experts: Houston's VC ecosystem has set the foundation — now we need scale

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve. Continue reading.

UH lands $4M NIH grant to study early signs of autoimmune disease

NIH funding

The University of Houston recently received a $4 million National Institutes of Health grant to support a 10-year longitudinal study to identify the earliest biological markers of autoimmune disease.

Led by Chandra Mohan, the Hugh Roy and Lillie Cranz Cullen Endowed Professor of Biomedical Engineering, the study aims to examine what causes Systemic Autoimmune Rheumatic Diseases (SARDs) and to identify targets for future treatments. The study will be carried out in collaboration with Dr. Karen Costenbader at Harvard Medical School, Boston.

SARDs include conditions like rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome and systemic sclerosis—all are considered chronic diseases currently without a cure. Autoimmune diseases affect over 30 million people globally, according to UH.

SARDs occur when the body’s immune system attacks healthy, non-threatening tissues and organs. According to UH, in these diseases, the body often attacks nuclear antigens, creating anti-nuclear autoantibodies, which can be early detection signs for SARDs in more than 50 percent of patients, Mohan says.

Researchers will study blood samples and environmental exposure over the 10 years to better understand anti-nuclear autoantibodies.

“Collectively, these studies will help identify the genetic, environmental and cellular factors that are operative at the two steps of SARD development, namely the emergence of anti-nuclear autoantibodies and disease onset,” Mohan said in a news release. “ More importantly, these studies will highlight functional molecular pathways and mechanisms that may be operative at each step."

Mohan predicts that looking at SARDs’ shared characteristics, rather than each disease individually, could help identify more treatment methods.

“Individual SARDs have been examined in silos without an attempt to discern shared underlying features at the molecular level,” he added in the release. “Current understanding of the initial (and likely shared) origins of SARDs is only rudimentary but urgently needed to develop means for prevention and treatment.”

Earlier this year, UH also received an $11 million NIH grant to conduct a first-of-its-kind study of early language development in children ages 18 to 24 months. Read more here.
