Houston biotech company Pulmotect Inc. has embarked on two clinical drug trials that could create weapons for the battle against the novel coronavirus.

Pulmotect gained permission from the U.S. Food and Drug Administration to test its inhaled drug, PUL-042, as a way to prevent coronavirus infections and to slow the early progression of COVID-19, the potentially fatal disease caused by the novel coronavirus. Pulmotect developed PUL-042 to activate the lungs' front-line defense against respiratory infections, and now it's being enlisted in the race to devise coronavirus treatments and cures.

"We have demonstrated PUL-042's unique ability to stimulate the immune system in the lungs to protect against a wide range of pathogens in multiple animal models," Dr. Colin Broom, CEO of Pulmotect, says in a May 7 release. "Pulmotect is optimistic that its immune-stimulating technology could be useful in mitigating the threats of [the coronavirus] and future emerging pathogens, and protecting vulnerable populations."

Unlike a vaccine, which typically takes 10 to 15 years to bring to the market, PUL-042 promises much faster deployment as scientists and health care workers wage war against COVID-19.

Each of the two clinical trials, both in the second phase, is being conducted at 10 sites across the U.S., including locations in Houston. In all, 20 sites are participating. Money for the trials came from the company's recently completed $12 million round of series B funding.

Pulmotect's partner in the trials is Covington, Kentucky-based CTI Clinical Trial and Consulting Services Inc. PARI Respiratory Equipment Inc., whose North American headquarters is in Midlothian, Virginia, is supplying medical equipment known as nebulizers to administer Pulmotect's inhaled drug.

"Both clinical trials are placebo-controlled to objectively evaluate safety and efficacy," Broom says in a May 5 release.

"In the first study, up to four doses of PUL-042 or placebo will be administered to 200 subjects by inhalation over a 10-day period to evaluate the prevention of infection and reduction in severity of COVID-19. In the second study, 100 patients with early symptoms of COVID-19 will receive the treatment administered up to three times over six days. In both trials, subjects will be followed up for 28 days to assess the effectiveness and tolerability of PUL-042."

Previous experiments conducted by Pulmotect indicate PUL-042 effectively protects mice against severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), which are caused by coronaviruses that differ from the COVID-19 virus. Researchers performed those tests at the University of Texas Medical Branch at Galveston.

PUL-042 initially was developed to fight respiratory problems in cancer patients undergoing chemotherapy, which weakens the immune system. But the drug offers the potential to prevent or treat an array of respiratory infections caused by viruses, bacteria, or fungi.

"We have always considered PUL-042 to have the potential for the prevention and treatment of emerging epidemics and pandemics like the one we currently face," Broom says.

A separate trial of PUL-042 is underway in London. There, the drug is being tested on patients with chronic obstructive pulmonary disease (COPD) who are susceptible to lung infections. COPD is an inflammatory disease that blocks airflow from the lungs. People with COPD face a heightened risk of conditions like heart disease and lung cancer, the Mayo Clinic says.

Researchers at MD Anderson Cancer Center and Texas A&M University invented Pulmotect's PUL-042, which holds patents in 10 countries. Pulmotect, founded in 2007, emerged from Houston's Fannin Innovation Studio, which fosters early stage companies in the life sciences sector.

Mental Health Match, a Houston-based startup that uses tech to easily connect people to mental health professionals, has announced the opportunity for 100 Texas residents to get their first appointment free and remotely.

The company cites data that shows:

  • A 78 percent increase in Texans who are concerned about their marriage
  • A 71 percent increase in Texans concerned with their parenting or their children
  • A 35 percent spike in Texans feeling panicked

"You might be practicing social distancing, but you are not alone. It is easier to make it through this together if you can get support and guidance from a skilled professional. That's why we're working with therapists across Texas to provide a free session to individuals who need it most," says Ryan Schwartz, founder of Mental Health Match, in a news release.

Texans can apply for the free sessions online on a first-come, first-served basis.

Medical Informatics Corp.

Houston-based Medical Informatics has created a virtual ICU program, called Sickbay, and the tech tool is being used to remotely monitor patients in Houston Methodist. The program works around the clock from a control hub to use artificial intelligence and algorithms to monitor patients.

The company, which recently moved into its office in TMCx+, announced major growth in January, just ahead of the coronavirus outbreak.

"We designed our Sickbay platform to give lost data back to doctors, nurses and other members of the care team so they could save more lives," says Vincent Gagne, vice president of product for MIC, in a news release. "In fact, our apps are built in collaboration with our clients, such as Texas Children's Hospital and Houston Methodist. Having these facilities blocks away from our headquarters accelerates that collaboration and development."

MolecularMatch

MolecularMatch, a Houston startup focused on clinical informatics, has launched a free portal that accumulates research and clinical trials for COVID-19. The company is a tenant of TMCx+ and a portfolio company of Houston-based venture capital group GOOSE.

"The number of therapeutic cures and vaccines being tested are growing at an astounding rate," says Eric Pulaski, CEO at MolecularMatch, in a news release. "Our tools make it easier for clinicians and patients to find the help they need. Hopefully, we can help save lives by shortening the time it takes to get more patients into clinical trials and by speeding up research to find cures and vaccines."

The product uses the company's artificial intelligence-backed curation platform and is updated every two to three days.

Luminare

Founded in 2014, Houston-based health care software startup Luminare Inc. seeks to prevent sepsis, a life-threatening reaction to a host of infections that causes about one-third of U.S. hospital deaths. Recently, though, Luminare pivoted to address another health concern — the threat of the novel coronavirus.

After the novel coronavirus surfaced, Luminare retooled its sepsis-detection platform to create a free online self-assessment test for people who suspect they've contracted the virus. The test, available at CheckForCorona.com, helps someone figure out whether they should seek a coronavirus test.

An online screening typically takes less than two minutes. The confidential, secure assessment complies with guidelines from the U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO). Based on your assessment results, you might be directed to contact your local health department or, in the worst-case scenario, call 911. Click here to read more.

Denver-based Manatee was just announced to be selected for the 2020 TMCx cohort, and — while programming is beginning virtually — the startup will be enroute to Houston as soon as it's safe. Manatee focuses on providing connected, everyday therapy for kids.

In light of the effects of COVID-19 on both parents and children, Manatee has allowed users to register for three months free. Individuals can apply online.

Moleculin Biotech Inc.

Houston-based Moleculin Biotech Inc., a clinical stage pharmaceutical company that typically focuses on cancer treatment, announced that it has filed for a new patent for its use of one of its products to be used against the coronavirus and other potential viruses.

This patent application is for Moleculin's WP1122, and the company has entered into a partnership with a major Texas university to advance its research.

"We've actually been working on the antiviral potential of WP1122 for some time now," says Walter Klemp, Moleculin's chairman and CEO, in a news release, "but the rise of COVID-19 has obviously placed a new sense of urgency on what we are doing. We hope to be generating animal data on WP1122's antiviral potential in the near term."

Pulmotech Inc.

Experiments conducted by clinical-stage, Houston-based biotechnology company Pulmotect Inc. show its PUL-042 inhaled drug has proven effective in protecting mice against two types of coronavirus: severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Researchers performed those tests at the University of Texas Medical Branch at Galveston.

In the Galveston experiments, a single inhaled dose of PUL-042 protected lab mice from the SARS virus, and it greatly reduced the amount of virus in their lungs after the mice became infected with SARS or MERS.

"With the risks of virulent coronaviruses and other threats increasing, as shown by the recent outbreak in Wuhan that has already spread from China to other countries including the United States, Pulmotect is optimistic that its immune-stimulating technology could be useful in mitigating the threats of current and emerging pathogens and protecting vulnerable populations," says CEO Dr. Colin Broom in a news release.

A drug being developed by a Houston biopharmaceutical company eventually could help combat what the World Health Organization has proclaimed a global health emergency.

Experiments conducted by clinical-stage biotechnology company Pulmotect Inc. show its PUL-042 inhaled drug has proven effective in protecting mice against two types of coronavirus: severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Researchers performed those tests at the University of Texas Medical Branch at Galveston.

In the Galveston experiments, a single inhaled dose of PUL-042 protected lab mice from the SARS virus, and it greatly reduced the amount of virus in their lungs after the mice became infected with SARS or MERS.

"With the risks of virulent coronaviruses and other threats increasing, as shown by the recent outbreak in Wuhan that has already spread from China to other countries including the United States, Pulmotect is optimistic that its immune-stimulating technology could be useful in mitigating the threats of current and emerging pathogens and protecting vulnerable populations," says CEO Dr. Colin Broom in a news release.

The ability of PUL-042 to ward off the newest type of coronavirus, 2019-nCoV, hasn't been tested yet. However, the drug eventually could help prevent the new virus from spreading, says Broom, who joined Pulmotect as CEO last fall. A separate study would be required to evaluate PUL-042 in patients exposed to 2019-nCoV, he says.

"PUL-042 has the potential to prevent and treat respiratory complications in many high-risk patient populations, including those where no effective therapies are currently available, as is the case with the current coronavirus outbreak," Brenton Scott, president and chief operating officer of Pulmotect, says in the release.

Since its discovery in late December 2019 in Wuhan, China, nearly 9,800 people around the world were infected with 2019-nCoV as of January 31, The New York Times reported. Of those people, more than 200 died. On January 30, the World Health Organization (WHO) declared the virus outbreak a global health emergency.

No specific treatment or cure for 2019-nCoV virus is available. This virus is among seven known coronaviruses.

Symptoms of the Wuhan coronavirus include fever, cough, and shortness of breath, according to the U.S. Centers for Disease Control and Prevention (CDC). The virus can cause pneumonia, SARS, kidney failure, or even death, the Virginia Department of Health says.

PUL-042 "would be a great tool to have available for future outbreaks and epidemics, in addition to being used more routinely for more common infections," Broom says.

Fighting coronaviruses is a potential byproduct of PUL-042.

Initially, Pulmotect is focusing development of PUL-042 on the prevention and treatment of respiratory complications suffered by cancer patients with suppressed immune systems. Phase 1 clinical trials already have taken place in the U.S., and Phase 2 clinical trials are scheduled for later this year.

A separate trial of PUL-042 is underway in London. There, the drug is being tested on patients with chronic obstructive pulmonary disease (COPD) who are prone to lung infections. COPD is an inflammatory disease that blocks airflow from the lungs. People with COPD face a heightened risk of conditions like heart disease and lung cancer, the Mayo Clinic says.

Broom says PUL-042 is a few years away from being considered for approval by the U.S. Food and Drug Administration (FDA).

To date, Pulmotect has raised more than $28 million in outside funding. Founded in 2007, Pulmotect emerged from Houston's Fannin Innovation Studio, which nurtures early stage companies in the life sciences sector.

Patents for PUL-042, invented by MD Anderson Cancer Center and Texas A&M University, have been issued in nine countries.

Houston biopharmaceutical company brings on new CEO to grow company

Head honcho

With a veteran of the biopharmaceutical industry now aboard as its CEO and an executive at pharmaceutical giant AstraZeneca now serving on its board, Houston-based biopharmaceutical company Pulmotect Inc. is poised for progress.

In September, Dr. Colin Broom joined Pulmotect as CEO. He previously was CEO of Ireland-based Nabriva Therapeutics plc, a biopharmaceutical company that went public in 2015. During Broom's tenure at Nabriva, he helped develop the recently approved drug Xenleta, which treats bacterial pneumonia. Before that, he was chief scientific officer at Pennsylvania-based pharmaceutical company ViroPharma Inc., which Massachusetts-based Shire plc purchased for $4.2 billion in 2014.

Broom's hiring came on the heels of Kumar Srinivasan being named to Pulmotect's board of directors. Srinivasan is vice president of United Kingdom-based AstraZeneca and is its global head of business development and licensing for biopharmaceuticals R&D.

Researchers at MD Anderson Cancer Center and Texas A&M University invented Pulmotect's main product, PUL-042, which holds patents in nine countries. Pulmotect, founded in 2007, emerged from Houston's Fannin Innovation Studio, which nurtures early stage companies in the life sciences sector.

"Attracting such a highly regarded and proven CEO as Colin is a clear signal of the power and potential of Pulmotect's development program," Pulmotect's executive chairman, Leo Linbeck III, founder and chairman of Fannin, says in a release. "Under his leadership, I'm confident that we will advance our technology further into the clinic and closer to the marketplace. His addition is a real game-changer for the company."

Both Broom and Srinivasan are focusing on clinical trials for Pulmotect's PUL-042 product, an inhaled therapy that holds the potential to prevent or treat respiratory infections caused by bacteria, viruses, or fungi. The current Phase 2 trial is evaluating the effectiveness of PUL-042 in treating patients with mild chronic obstructive pulmonary disease (COPD) who've been exposed to a respiratory virus. The current trial is supposed to be followed by additional Phase 2 trials.

COPD, which affects 30 million Americans, is the No. 3 cause of death in the U.S., according to the COPD Foundation. Pulmotect says 40 percent of COPD-related costs could be avoided by preventing complications and hospitalizations, which typically result from COPD problems triggered by a bacterial or viral infection. PUL-042 could substantially decrease those complications, the company says.

Pulmotect seeks to gear PUL-042 toward patients with cancer who are undergoing chemotherapy, as their weakened immunity makes them highly susceptible to pneumonia, Broom says. If the product proves effective with those patients, then people at risk of developing respiratory infections also might benefit from it, including COPD patients and flu patients, he says.

To date, Pulmotect has raised more than $28 million in funding. That includes about $18 million in research grants, including a $7 million grant from the Cancer Prevention and Research Institute of Texas, as well as seven grants from the Small Business Innovation Research program.

Two of Pulmotect's three full-time employees work in Houston, and a team of consultants supports their work, Broom says. A small number of employees might be added during the current Phase 2 trial. Hiring would need to be ramped up if the Phase 2 trial demonstrates that PUL-042 works, he says.

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

guest column

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.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
