A new Houston biotech company won a special award at the 16th Annual SXSW Pitch Award Ceremony earlier this month.

 Phiogen, one of 45 companies that competed in nine categories, was the winner for best inclusivity, much to the surprise of the company’s CEO, Amanda Burkhardt.

Burkhardt tells InnovationMap that while she wanted to represent the heavily female patient population that Phiogen seeks to treat, really she just hires the most skilled scientists.

“The best talent was the folks that we have and it ends up being we have three green card holders on our team. As far as ethnicities, we have on our team we have Indian, African-American, Korean, Chinese Pakistani, Moroccan and Hispanic people and that just kind of just makes up the people who helped us on a day-to-day basis,” she explains.

Phiogen was selected out of 670 companies to be in the health and nutrition category at SXSW.

“We did really well, but there was another company that also did really well. And so we were not selected for the pitch competition, which we were a little bummed about because I killed the pitch,” Burkhardt recalls.

But Phiogen is worthy of note, pitch competition or not. The new company spun off from research at Dr. Anthony Maresso’s TAILOR Labs, a personalized phage therapy center at Baylor College of Medicine, last June.

“Our whole goal is to create the next generation of anti-infectives,” says Burkhardt.

That means that the company is making alternatives to antibiotics, but as Burkhardt says, “We’re hoping to be better than antibiotics.”

How does it work? Bacteriophages are viruses that infect bacteria.

“You can imagine them as the predators in the bacteria world, but they don't infect humans. They don't affect animals. They only infect bacteria,” Burkhardt explains.

Phiogen utilizes carefully honed bacteriophages to attack bacteria that include the baddies behind urinary tract infection (UTI), bacteremia (bacteria in the blood), and skin wounds.

The team’s primary focus is on treatment-resistant UTI. One example was a male patient who received Phiogen’s treatment thanks to an emergency-use authorization from the FDA. The gentleman had been suffering from an infection for 20 years. He was treated with Phiogen’s bacteriophage therapy for two weeks and completely cleared his infection with no recurrence.

But Phiogen has its sights set well beyond the first maladies it’s treated. An oft-quoted 2016 report projected that by 2050, 10 million people a year will be dying from drug-resistant infections.

“A lot of scientists call it the silent pandemic because it's happening now, we're living in it, but there's just not as much being said about it because it normally happens to people who are already in the hospital for something else, or it's a comorbidity, but that's not always the case, especially when we're talking about urinary tract infections,” says Burkhardt.

Bacteriophages are important because they can be quickly trained to fight against resistant strains, whereas it takes years and millions of dollars to develop new antibiotics. There are 13 clinical trials that are currently taking place for bacteriophage therapy. Burkhardt estimates that the treatment method will likely gain FDA approval in the next five years.

“The FDA actually has been super flexible on progressing forward. Because they are naturally occurring, there's not really a safety risk with these products,” she says.

And Burkhardt, whose background is in life-science commercialization, says there’s no better place to build Phiogen than in Houston.

“You have Boston, you have the Bay [Area], and you have the Gulf Coast,” she says. “And Houston is cheaper, the people are friendlier, and it’s not a bad place to be in the winter.”

She also mentions the impressive shadow that Helix Park will cast over the ecosystem. Phiogen will move later this year to the new campus — one of the labs selected to join Baylor College of Medicine.

And as for that prize, chances are, it won’t be Phiogen’s last.

3 Houston research groups dive into game changing COVID-19 projects

Research roundup

Researchers across Houston are working on COVID-19 innovations every day, and scientists are constantly finding new ways this disease is affecting humankind.

Wastewater detection, mental illness effects, a software solution to testing — here's your latest roundup of research news in Houston.

According to researchers at Baylor College of Medicine, who are working in partnership with the Houston Health Department and Rice University, testing the city's wastewater for SARS-CoV2 can help predict where outbreaks are likely to happen.

In May, researchers analyzed wastewater samples that were collected every week from 39 sites in the city and found traces of the virus. The research project was directed by Baylor microbiologist Dr. Anthony Maresso, director of BCM TAILOR Labs.

"This is not Houston's first infectious disease crisis," Maresso says in a news release. "Wastewater sampling was pioneered by Joseph Melnick, the first chair of Baylor's Department of Molecular Virology and Microbiology, to get ahead of polio outbreaks in Houston in the 1960s. This work essentially ushered in the field of environmental virology, and it began here at Baylor. TAILOR Labs is just continuing that tradition by providing advanced science measures to support local public health intervention."

The researchers will continue into 2021 and are working with the city and local governments on their findings.

"It's a cost effective way to gauge Houston's total viral load. It tracks well ahead of positivity rate, 10 days in some cases," sways Dr. Austen Terwilliger, director of operations at TAILOR, in the release. "At the moment, we are at the lowest viral levels since we started sampling, which is excellent news."

University of Houston researchers looking into effect of pandemic on mental illness

While physical health and economic impacts of the coronavirus have been the focus of attention amid the pandemic, mental health effects are estimated to inflict more damage if not address, according to new research by Michael Zvolensky, University of Houston professor of psychology and director of the Anxiety and Health Research Laboratory/Substance Use Treatment Clinic.

Zvolensky has published two papers on his research discussing the psychological behavior issues related to the COVID-19 pandemic from a behavioral science perspective, according to a press release from UH.

"The impact of COVID-19 on psychological symptoms and disorders, addiction and health behavior is substantial and ongoing and will negatively impact people's mental health and put them at greater risk for chronic illness and drug addiction," reports Zvolensky in Behaviour Research and Therapy. "It will not equally impact all of society. Those at greater risk are those that have mental health vulnerabilities or disorders."

For those who 'catastrophize' the pandemic, Zvolensky explains in his paper, the impact from stress is increased — as is the possibility for substance abuse.

"That sets in motion a future wave of mental health, addiction and worsening health problems in our society. It's not going to go away, even with a vaccination, because the damage is already done. That's why we're going to see people with greater health problems struggling for generations," says Zvolensky in the release.

He evaluated a group of 160 participants on pandemic-related fear and worry and substance abuse as a coping method. The "results may provide critical clinical information for helping individuals cope with this pandemic," he says.

Can software help save lives in this pandemic? A Rice University computer scientist thinks it's worth a shot.

Bioinformatics researcher Todd Treangen is working with a molecular diagnostics company to optimize the design and computational evaluation of molecular detection assays for viral RNA of SARS-CoV-2, according to a press release from Rice. Great Basin Scientific and the Rice researchers hope their work will streamline the development and commercialization of COVID-19 testing.

"This exciting collaboration with Great Basin will allow for computational methods and software developed in my research group to directly contribute to fast, sensitive and affordable detection and monitoring of SARS-CoV-2 and emerging pathogens," Treangen said.

The company, which is based in Salt Lake City, will use Treangen lab's novel bioinformatics software called OliVar to work on the diagnostic test. Great Basin Scientific is expected to seek emergency use authorization for the test from the Food and Drug Administration later this year.

Rice team keeps CO2-to-fuel devices running 50 times longer in new study

Bubbling Up

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also recently shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.
