A Houston-based biotech company announced last week that it has gotten the approval it was seeking from the U.S. Food and Drug Administration to continue testing its COVID-19 treatment that uses stem cells.

Celltex has received approval from its Investigational New Drug application, or IND, to look into stem cells — specifically Autologous Adipose Tissue-Derived Mesenchymal Stem Cells, or AdMSCs — and their effect on COVID-19 patients.

"The FDA's approval of our IND is not only a critical milestone for Celltex, but also for everyone who has been affected by COVID-19," says David G. Eller, Celltex chairman and CEO. "I am optimistic that our findings will result in favorable outcomes that will improve lives today and for generations to come."

Celltex has been in the stem cell business for nearly a decade and has treated patients with debilitating diseases like multiple sclerosis, Parkinson's, rheumatoid arthritis, and more. Eller says he's been considering how Mesenchymal Stem Cells, or MSCs, could be used amid the pandemic.

"Throughout the entire pandemic, MSCs have shown promise for combatting symptoms and complications associated with COVID-19, and as the nation's leading commercial MSC banking and technology company, Celltex has the unique ability to transition these initial findings into a clinical trial," Eller says.

The FDA clearance will allow for a phase two trial "that will evaluate the safety and prophylactic efficacy of AdMSCs against COVID-19," according to the release. There will be 200 patients across multiple centers that will be involved in the placebo-controlled study.

Celltex offices out of the Galleria area and has laboratory operations of its wholly-owned Mexican subsidiary are located in Hospital Galenia in Cancún, Quintana Roo, Mexico. Last year, Celltex planned an expansion into Saudi Arabia and also has a presence in Europe.

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.

Moleculin Biotech Inc.

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.

Celltex

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 biotech company plans expansion into Saudi Arabian market

On the move

A Houston company that uses stem cell technology to treat patients suffering from degenerative diseases is taking its patented technology to another continent.

Celltex Therapeutics Corp. has entered a memorandum of understanding with Saudi Arabia's Research Products Development Company. As a part of the partnership solidified by the MOU, Celltex will open an office in Riyadh, Saudi Arabia, later this year. The new office will aid the commercialization of Celltex's technology and expand the company's presence to Saudi Arabia.

"We are honored to forge a relationship with Saudi Arabia," says David G. Eller, CEO and chairman of Celltex, in a release. "Our collaboration with this first-rate global cohort furthers our commitment to initiating breakthroughs in regenerative medicine, and our presence in Riyadh will further expand our opportunities to improve the quality of life of those in need."

The MOU is a part of the country's effort to diversify the economy that's been dominated by oil and gas, the release says. As a part of Saudi Arabia's National Industrial Development and Logistic Program, Celltex and other United States companies were invited to Riyadh to sign MOUs in January, which resulted in billions of dollars in Saudi investment, per the release.

On February 4, the two parties reconvened at Celltex's office in Houston. The group included top Saudi dignitaries, Abdulmohsen Almajnouni, CEO of RPDC, as well as others.

"We are excited to explore business opportunities with Celltex, a biotechnology company with the innovative proprietary technology, patents and know-how for the cultivation and therapeutic application of stem cells," Almajnouni says in the release.

Celltex currently extracts patients' stem cells at various partner facilities across the United States, but implementation happens at a hospital in Mexico, due to FDA regulations and red tap. However, Eller doesn't foresee this being the process forever.

"We have very good relations with the US FDA," he says in an InnovationMap article. "They are very interested in what we know. Our approach is really is very progressive and we've grown every year."

The company'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.

Marla Murphy didn't feel like she was doing enough to promote health and wellness with her platform, The Blonde Pantry. So, she expanded it to incorporate locally sourced produce and easy-to-make recipes she gets ready every weekend to deliver to her members by Monday.

"It's not about selling meals and moving on, I want this to be a lifestyle company that is really founded and has deep roots in Houston," says Murphy in a InnovationMap story.

Murphy tells InnovationMap that in the next year she hopes to expand into the retail space and find a bigger commercial kitchen to function as their own. She also hopes to partner with companies outside of food and continue to nourish lives in someway.

David Eller, chairman, co-founder and CEO of Celltex

Stem cell treatment is personal to David Eller, chairman, co-founder and CEO of Celltex. Eller had the treatment in hopes of resolving pain from a college football injury.

"I would go to work and put four to six Advil in my pocket," Eller says in an InnovationMap story about Celltex's technology. Within months, he stopped needing those pills.

Houston-based Celltex tracks its progress 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.

Katharine Forth, founder and CEO of Zibrio

Katharine Forth has used a technology she developed with her colleague at NASA to measure balance in astronauts to create a device that any terrestrial human can now use from the comfort of their own homes.

"The machines typically used for balance measurement can be as large as a telephone booth, so we invented a new way to measure postural control using a much smaller mechanism that fit inside a moon boot," Forth says in an InnovationMap article about Zibrio, The Balance Company. Zibrio, The Balance Company.

Zibrio is now a finalist for the 2019 SXSW Pitch in the health and wearables category and will take its balance technology to the stage in March.

Regeneration nation

The medical community has former governor Rick Perry to thank for a major stride in regenerative medicine.

"He had just gotten elected for the last time and he wanted to leave a legacy. He was tired of people going to Japan or Germany when they needed stem cells," recalls David Eller, chairman, co-founder and CEO of Celltex.

That was 2011, the year that the former president of Dupont Pharmeceuticals-Europe and orthopedic surgeon Dr. Stanley Jones incorporated as Celltex. Perry got the law passed to make it legal to harvest his stem cells, and Jones implanted them while the governor was under the knife for a spinal fusion surgery.

Perry resigned from the Celltex board in 2017, but the truth is, the company no longer needed his clout. Just a year after its debut, the company had in excess of 200 clients, each paying a banking enrollment fee of $6,500. Now, there are close to 1,300.

From research to recovery
Eller is originally from Houston, and he says his hometown is the ideal home base for the company, with its access to the world's largest medical center. The Galleria-area office and lab employ 35 people, with about 50 workers worldwide.

Close to the same time that his friend Perry received his stem cells, Eller also had the treatment in hopes of resolving pain from a college football injury.

"I would go to work and put four to six Advil in my pocket," the CEO recalls.

Within months, all of them remained in his pocket.

But others have had even more dramatic results. Celltex checks in with patients three, six and nine months after their treatments to find out how they're doing. 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.

Implementation and the FDA
Celltex's chief scientific officer, Dr. Jane Young, co-authored a study of two severe juvenile rheumatoid arthritis patients whose conditions didn't respond to standard treatments. After trying stem cells, both reported marked improvement in autonomic nervous system and immune function.

Stem cells are gathered through a patient's fat, which can be extracted at any of the 80 facilities around the country that partner with Celltex. The fat is processed at the Houston lab, where processing takes 30 to 35 days.

"We have 15 billion cells in process each day," says Erik Eller, the company's vice president of operations, clarifying that some clients' cells grow faster than others'.

It takes 14 days to come out of cryostasis and leave the lab. From there, the stem cells travel to Hospital Galenia in Cancun, Mexico for implantation, since the FDA categorizes stem cells as a drug if they have expanded as they do at Celltex. That means that a patient cannot use his own stem cells in the United States without a clinical trial. To circumnavigate the red tape, Celltex has simply partnered with the luxurious Mexican hospital.

This is currently the company's biggest challenge, says David Eller, but one he expects to overcome.

"We have very good relations with the US FDA," he says. "They are very interested in what we know. Our approach is really is very progressive and we've grown every year."

Ultimately, Eller hopes to be able to implant stem cells in the United States. But the company's foreign growth is a good start. Celltex is now operating in the Bahamas and is hoping to add Australian extraction facilities sometime this year. They are also in negotiations with a team from Saudi Arabia interested in expanding Celltex to the Middle East.

Other goals for Celltex include improvements both in the realms of sales and revenue and streamlining and improving the safety and efficacy of treatment. Research collaborations with Baylor College of Medicine and Texas A&M will help with the company's medical credibility. This all may help to convince the FDA to allow the Celltex to get a biologics license, the final proof that it is not a drug company. But no matter how it's categorized, Celltex is growing exponentially as its cells.

CPRIT CEO: Houston’s $2B in funding is transforming cancer research and prevention

fighting cancer

With its plethora of prestigious health care organizations like the University of Texas MD Anderson Cancer Center, UTHealth Houston, and the Baylor College of Medicine, Houston sits at the heart of cancer research and prevention in Texas.

Of course, it takes piles of cash to support Houston’s status as the state’s hub for cancer research and prevention. Much of that money comes from the Cancer Prevention and Research Institute of Texas (CPRIT).

Data supplied by CPRIT shows organizations in Harris County gained $2.3 billion in institute funding from 2009 through 2025, or nearly $145 million per year. That represents almost 60 percent of the roughly $4 billion that CPRIT has granted to Texas institutions over a 16-year period.

“The life sciences ecosystem that has developed and changed in Houston is phenomenal,” Kristen Doyle, who became the agency’s CEO in July 2024, tells InnovationMap. “In the next decade, we will look back and see a great transformation.”

That ecosystem includes more than 1,100 life sciences and biotech companies, according to the Greater Houston Partnership.

Houston plays critical role in clinical trials

Texas voters approved the creation of CPRIT in 2007. Twelve years later, voters agreed to earmark an extra $3 billion for CPRIT, bringing the state agency’s total investment in cancer research and prevention to $6 billion.

To date, CPRIT money has gone toward recruiting 344 cancer researchers to Texas (mainly to Houston) and has supported cancer prevention services for millions of Texans in the state’s 254 counties. CPRIT funding has also helped establish, expand, or relocate 25 cancer-focused companies. In Houston, MD Anderson ranks as the No. 1 recipient of CPRIT funding.

Regarding cancer research, Doyle says Houston plays a critical role in clinical trials.

“[Clinical trials are] something that CPRIT has focused on more and more. Brilliant discoveries are crucial to this whole equation of solving the cancer problem,” Doyle says. “But if those brilliant ideas stay in the labs, then we’ve all failed.”

Researchers conduct more clinical trials in Houston than anywhere else in the U.S., the Greater Houston Partnership says.

Doyle, a 20-year survivor of leukemia, notes that a minority of eligible patients participate in clinical trials for cancer treatments, “and that’s one of the reasons that it takes so long to get a promising drug to market.”

An estimated 7 percent of cancer patients sign up for clinical trials, according to a study published in 2024 in the Journal of Clinical Oncology.

MD Anderson takes on cancer prevention

Doyle also notes that Houston is leading the charge in cancer prevention.

“We get some national recognition for programs that have been developed in Houston that then can be replicated in other parts of the country,” she says.

Much of the work in Houston focusing on cancer prevention takes place at MD Anderson. The hospital reports that it has received more than $725 million from the CPRIT since 2007, representing approximately 18 percent of CPRIT’s total awards.

“These efforts can have profound impact on the lives of patients and their families, and this funding ensures our exemplary clinicians and scientists can continue working together to drive breakthroughs that advance our mission to end cancer,” Dr. Giulio Draetta, chief scientific officer at MD Anderson, said in a November news release, following the most recent CPRIT award for the hospital totaling more than $29 million.

CPRIT funding for Houston institutions supplements the more than $4.5 billion in federal funding for health and life sciences research and innovations that the Houston area received from 2020 to 2024, according to the Greater Houston Partnership.

“We are curing cancer every single day,” Doyle says of CPRIT. “Every step that we are taking — whether that’s funding great ideas or funding the clinical trials that are bringing promising drugs to Texas and to the world — we are making a difference.”

Houston energy tech co. breaks ground on low-cost hydrogen pilot plant

Coming Soon

Houston’s Lummus Technology and Advanced Ionics have broken ground on their hydrogen pilot plant at Lummus’ R&D facility in Pasadena, Texas.

The plant will support Advanced Ionics’ cutting-edge electrolyzer technology, which aims to deliver high-efficiency hydrogen production with reduced energy requirements.

“By demonstrating Advanced Ionics’ technology at our state-of-the-art R&D facility, we are leveraging the expertise of our scientists and R&D team, plus our proven track record of developing breakthrough technologies,” Leon de Bruyn, president and CEO of Lummus, said in a news release. “This will help us accelerate commercialization of the technology and deliver scalable, cost-effective and sustainable green hydrogen solutions to our customers.”

Advanced Ionics is a Milwaukee-based low-cost green hydrogen technology provider. Its electrolyzer converts process and waste heat into green hydrogen for less than a dollar per kilogram, according to the company. The platform's users include industrial hydrogen producers looking to optimize sustainability at an affordable cost.

Lummus, a global energy technology company, will operate the Advanced Ionics electrolyzer and manage the balance of plant systems.

In 2024, Lummus and Advanced Ionics established their partnership to help advance the production of cost-effective and sustainable hydrogen technology. Lummus Venture Capital also invested an undisclosed amount into Advanced Ionics at the time.

“Our collaboration with Lummus demonstrates the power of partnerships in driving the energy transition forward,” Ignacio Bincaz, CEO of Advanced Ionics, added in the news release. “Lummus serves as a launchpad for technologies like ours, enabling us to validate performance and integration under real-world conditions. This milestone proves that green hydrogen can be practical and economically viable, and it marks another key step toward commercial deployment.”
