A Houston-based biotech company has wrapped up enrollment for its most recent clinical trial of its cancer-fighting drug.

Moleculin Biotech Inc. (Nasdaq: MBRX) has launched its fourth ongoing trial — this time focusing on Cutaneous T-Cell Lymphoma, or CTCL, treatment. The company's other three trials include treatment for glioblastoma, an aggressive brain cancer, pancreatic cancer, one of the most virulent killers in oncology, and acute myeloid leukemia, or AML.

To treat these various types of cancers, Moleculin has a several drugs it's in preclinical or clinical trials testing — most biotech companies have only one they focus on. WP1220 is the drug that will be used in this trial for topical CTCL treatment of the cancer's resulting skin lesions.

"We believe there continues to be an unmet need for an improved topical therapy for Stage I-III CTCL skin lesions," says Walter Klemp, Moleculin's chairman and CEO, in a news release, "especially one that may avoid significant unwanted side effects."

WP1220 is what's known as a p-STAT3 inhibitor. STAT3 is a transcription factor that encourages tumor development. Moleculin's technology directly attacks the tumor, but also quiets T Cells, which allows the body's own immune system to fight the cancer itself. Essentially, it works both as chemotherapy and immunotherapy.

"This proof of concept, if successful, could be an important first demonstration of a therapeutic effect in humans from such a p-STAT3 inhibitor," Klemp continues. "We are pleased with how quickly this trial reached full recruitment and we are hopeful to be able to announce results from this trial yet this year."

Klemp founded the company in 2007, and Moleculin went public in 2016. Now, with the company's four clinical trials, Moleculin is even closer to saving lives with its products.

"Notwithstanding the relatively rare nature of CTCL, we believe showing activity with one of our STAT3 inhibitors, within our WP1066 family of molecules, could be an indicator of both the value of p-STAT3 as a target and the potential for our drugs in other cancers where STAT3 is highly activated," Klemp says in the release.

5 Houston biotech companies taking health care to new levels

The future is now

Houston is the home of the largest medical center in the world, so it comes as no surprise that the Bayou City is also home to breakthrough technologies. Here are five Houston companies developing some of this biotech advancements.

Immunotherapy and personalized medicine get all the headlines lately, but in the fight against cancer, a natural compound created by bees could beat them in winning one battle.

In 2007, chairman and CEO Walter Klemp founded Moleculin Biotech Inc. as a private company. The former CPA had found success in life sciences with a company that sold devices for the treatment of acne. That introduction into the field of medical technology pushed him toward more profound issues than spotty skin.

"Coincidentally, the inventor of that technology had a brother who was a neuro-oncologist at MD Anderson," Klemp recalls.

The since-deceased Dr. Charles Conrad slowly lured Klemp into what he calls the "cancer ecosphere" of MD Anderson. In 2016, the company went public. And it looks like sooner rather than later, it could make major inroads against some of the toughest cancers to beat. Read the full story here.

Breakthrough biotech doesn't have to just be for humans. More than three years after its founding, Houston-based veterinary biotech company CAVU Biotherapies' had its first cancer patient: a black Labrador in Pennsylvania diagnosed with B-cell lymphoma.

Dr. Colleen O'Connor, CEO and founder of CAVU Biotherapies, established the company in July 2015 with a goal to help pets live longer post-cancer diagnoses. O'Connor, who earned a PhD in toxicology with a specialty in immunology, has more than a decade of hands-on experience researching cancer treatments.

"Our goal is to scale up and be able to increase our dogs' qualities of life with us," O'Connor said. "We want to keep families intact longer and we want to be able to modernize cancer care for our animals." Read the full story here.

Innovative Biochips

Innovative Biochips, a Houston-based biotechnology company, is one step closer to commercializing technology that the company hopes will provide an opportunity for researchers to detect diseases earlier.

The company was founded three years ago by Dr. Lidong Qin, a professor at the Houston Methodist Research Institute's department of nanomedicine. He launched iBiochips as an independent faculty startup that licensed technology from Houston Methodist. Qin says he wanted to engineer and manufacture devices that focus on revolutionizing single-cell isolation and genetic analysis. Read the full story here.

A Houston stem cell company is making strides in regenerative medicine. Celltex's treatment has been proved effective with its patients. Eighty-three percent of multiple sclerosis patients have reported improvement of symptoms specific to their disease, as have 73 percent of Parkinson's sufferers. But the staggering fact is that 100 percent of 58 respondents with rheumatoid arthritis say they have benefited.

David Eller, chairman, co-founder and CEO of the company, also recently announced the company's expansion to Saudi Arabia. Read the full story here.

Ridgeline Therapeutics

Stan Watowich pictures a world where elderly people have the same healthy muscles they had at a younger age. Watowich is CEO of Ridgeline Therapeutics, a spin-off company of the University of Texas Medical Branch in Galveston where he is an associate professor of biochemistry and molecular biology, and he wants to make it clear that he is not going to cure aging.

"You and I are still going to get old," he says. "But we have our hopes that as we get old our muscles will stay healthy."

He's talking about the drug candidate, RLT-72484. It has been shown to reactivate muscle stem cells and regenerate skeletal muscle in aged laboratory mice. Read the full story here.

Axiom Space wins NASA contract for fifth private mission, lands $350M in financing

ready for takeoff

Editor's note: This story has been updated to include information about Axiom's recent funding.

Axiom Space, a Houston-based space infrastructure company that’s developing the first commercial space station, has forged a deal with NASA to carry out the fifth civilian-staffed mission to the International Space Station.

Axiom Mission 5 is scheduled to launch in January 2027, at the earliest, from NASA’s Kennedy Space Center in Florida. The crew of non-government astronauts is expected to spend up to 14 days docked at the International Space Station (ISS). Various science and research activities will take place during the mission.

The crew for the upcoming mission hasn’t been announced. Previous Axiom missions were commanded by retired NASA astronauts Michael López-Alegría, the company’s chief astronaut, and Peggy Whitson, the company’s vice president of human spaceflight.

“All four previous [Axiom] missions have expanded the global community of space explorers, diversifying scientific investigations in microgravity, and providing significant insight that is benefiting the development of our next-generation space station, Axiom Station,” Jonathan Cirtain, president and CEO of Axiom, said in a news release.

As part of Axiom’s new contract with NASA, Voyager Technologies will provide payload services for Axiom’s fifth mission. Voyager, a defense, national security, and space technology company, recently announced a four-year, $24.5 million contract with NASA’s Johnson Space Center in Houston to provide mission management services for the ISS.

Axiom also announced today, Feb. 12, that it has secured $350 million in a financing round led by Type One Ventures and Qatar Investment Authority.

The company shared in a news release that the funding will support the continued development of its commercial space station, known as Axiom Station, and the production of its Axiom Extravehicular Mobility Unit (AxEMU) under its NASA spacesuit contract.

NASA awarded Axiom a contract in January 2020 to create Axiom Station. The project is currently underway.

"Axiom Space isn’t just building hardware, it’s building the backbone of humanity’s next era in orbit," Tarek Waked, Founding General Partner at Type One Ventures, said in a news release. "Their rare combination of execution, government trust, and global partnerships positions them as the clear successor-architect for life after the ISS. This is how the United States continues to lead in space.”

Houston edtech company closes oversubscribed $3M seed round

fresh funding

Houston-based edtech company TrueLeap Inc. closed an oversubscribed seed round last month.

The $3.3 million round was led by Joe Swinbank Family Limited Partnership, a venture capital firm based in Houston. Gamper Ventures, another Houston firm, also participated with additional strategic partners.

TrueLeap reports that the funding will support the large-scale rollout of its "edge AI, integrated learning systems and last-mile broadband across underserved communities."

“The last mile is where most digital transformation efforts break down,” Sandip Bordoloi, CEO and president of TrueLeap, said in a news release. “TrueLeap was built to operate where bandwidth is limited, power is unreliable, and institutions need real systems—not pilots. This round allows us to scale infrastructure that actually works on the ground.”

True Leap works to address the digital divide in education through its AI-powered education, workforce systems and digital services that are designed for underserved and low-connectivity communities.

The company has created infrastructure in Africa, India and rural America. Just this week, it announced an agreement with the City of Kinshasa in the Democratic Republic of Congo to deploy a digital twin platform for its public education system that will allow provincial leaders to manage enrollment, staffing, infrastructure and performance with live data.

“What sets TrueLeap apart is their infrastructure mindset,” Joe Swinbank, General Partner at Joe Swinbank Family Limited Partnership, added in the news release. “They are building the physical and digital rails that allow entire ecosystems to function. The convergence of edge compute, connectivity, and services makes this a compelling global infrastructure opportunity.”

TrueLeap was founded by Bordoloi and Sunny Zhang and developed out of Born Global Ventures, a Houston venture studio focused on advancing immigrant-founded technology. It closed an oversubscribed pre-seed in 2024.

Texas space co. takes giant step toward lunar excavator deployment

Out of this world

Lunar exploration and development are currently hampered by the fact that the moon is largely devoid of necessary infrastructure, like spaceports. Such amenities need to be constructed remotely by autonomous vehicles, and making effective devices that can survive the harsh lunar surface long enough to complete construction projects is daunting.

Enter San Antonio-based Astroport Space Technologies. Founded in San Antonio in 2020, the company has become a major part of building plans beyond Earth, via its prototype excavator, and in early February, it completed an important field test of its new lunar excavator.

The new excavator is designed to function with California-based Astrolab's Flexible Logistics and Exploration (FLEX) rover, a highly modular vehicle that will perform a variety of functions on the surface of the moon.

In a recent demo, the Astroport prototype excavator successfully integrated with FLEX and proceeded to dig in a simulated lunar surface. The excavator collected an average of 207 lbs (94kg) of regolith (lunar surface dust) in just 3.5 minutes. It will need that speed to move the estimated 3,723 tons (3,378 tonnes) of regolith needed for a lunar spaceport.

After the successful test, both Astroport and Astrolab expressed confidence that the excavator was ready for deployment. "Leading with this successful excavator demo proves that our technology is no longer theoretical—it is operational," said Sam Ximenes, CEO of Astroport.

"This is the first of many implements in development that will turn Astrolab's FLEX rover into the 'Swiss Army Knife' of lunar construction. To meet the infrastructure needs of the emerging lunar economy, we must build the 'Port' before the 'Ship' arrives. By leveraging the FLEX platform, we are providing the Space Force, NASA, and commercial partners with a 'Shovel-Ready' construction capability to secure the lunar high ground."

"We are excited to provide the mobility backbone for Astroport's groundbreaking construction technology," said Jaret Matthews, CEO of Astrolab, in a release. "Astrolab is dedicated to establishing a viable lunar ecosystem. By combining our FLEX rover's versatility with Astroport's civil engineering expertise, we are delivering the essential capabilities required for a sustainable lunar economy."
