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.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
