How do you bring promising cancer research to the masses? TMC Innovation's Accelerator for Cancer Therapeutics was established with that question in mind.

Funded by a $5 million grant from CPRIT, or the Cancer Prevention and Research Institute of Texas, in 2019 and in collaboration with the Gulf Coast Consortia and the University of Texas Medical Branch, the first cohort began their intensive work in 2021. The deadline to join the next cohort is October 13.

Since its inception, ACT has seen the forming of 19 companies — two of which have been awarded CPRIT seed grants, along with four in contention for one this year — as well as $92 million in dilutive funding and $10 million in non-dilutive funding.

“We’ve recruited investigators and companies from the breadth and width of the state of Texas, so all the way from Lubbock to Galveston from Dallas to the Rio Grande Valley,” Ahmed AlRawi, program manager, tells InnovationMap. “We've had an amazing set of investigators who have gone through the program — 56 teams to be precise.”

AlRawi says that the first pillar of the program is education. To that end, the cohort works with entrepreneurs in residence like Michael Torres. Best known as the co-founder of ReCode Therapeutics, Torres says that one of his greatest passions lies in translating science into medicines. ReCode is a genetic medicines company that is currently clinical-stage. It’s raised more than $300 million in the last two years, certainly something to which scientist-entrepreneurs earlier in their careers would aspire.

A longtime resident of Dallas, Torres moved his family to Houston last year, calling it “the place to be for cancer startups in Texas.”

Initially, says Torres, Houston wasn’t on his radar. But thanks to a call from ACT external advisor Dan Hargrove, Torres realized that the city might be a fit for him and his goals.

“I wanted to find a project that I could help support, sort of take my experience as a cofounder and help guide the next great startup within the ecosystem,” he says.

Torres and AlRawi agree that the biggest successes to come out of ACT so far include March Biosciences, a company from the first cohort, which is focused on developing CAR-T cell strategies to help combat hematological cancers; CPRIT fundee, OmniNano Pharmaceuticals, which uses patented nanotechnology to co-deliver a pair of therapeutical agents to solid tumors; and the latest, CrossBridge Bio.

Part of the most recent cohort, Torres has joined Drs. Kyoji Tsuchikama and Zhiqiang An as the last company’s CEO. To that end, he’s partnered with the world-class researchers out of UT Health Houston to build a next-generation antibody drug conjugate company that he believes will produce “better and safer and more effective drugs than what's currently on the market today.”

All the more reason that Torres he’s glad to have moved to Houston at what he calls “a really exciting time.” He’s thankful for the Texas Medical Center and the relationships it fosters. “We're all sort of aligning on creating a sustainable biotech ecosystem,” he says. And the next big cancer fighting company may well emerge from ACT.

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.”
