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.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
