When it came time to name their cell therapy startup, Houston life science innovators simply had to look to their calendar.

“I would argue that March is the best month in Houston,” Sarah Hein tells InnovationMap. “We started talking about putting this company together during COVID, so we were outside a lot. And we actually got together in March.”

That’s why the CEO and her co-founders Max Mamonkin and Malcolm Brenner decided to name their company March Biosciences.

It's a fresh, unstuffy name for a startup that has an innovative take on cancer immunotherapy. Their lead asset is an advanced cellular therapy known as MB-105, an autologous CD5 CAR T cell therapy. For patients with T-cell lymphoma and leukemia who have failed all currently available lines of therapy, the prognosis is understandably extremely poor. But in a phase one study, MB-105 has been proven to safely treat those patients. The phase two study is expected to begin in the first half of 2024.

Hein met Mamonkin at the TMC Accelerator for Cancer Therapeutics (ACT), at which the alumna of Resonant Therapeutics and Courier Therapeutics was an entrepreneur in residence.

“It's a perfect example of the opportunities here in Houston where you can go from bench to bedside, essentially, in the same institution. And Baylor has been particularly good at that because of the Center for Cell and Gene Therapy,” says Hein.

The serial entrepreneur first came to Houston as a PhD student in molecular and cellular biology at Baylor College of Medicine, but during her studies she became excited by the startup ecosystem in her new hometown. After earning her degree, she became a venture fellow at the Mercury Fund. Her experience in both science and business made her an ideal candidate to take March Biosciences to the next level.

In September, the company announced that it formed a strategic alliance with CTMC (Cell Therapy Manufacturing Center), a joint venture between MD Anderson Cancer Center and National Resilience.

“Our unique risk-sharing model allows us to collaborate with organizations like March Biosciences to accelerate the development and manufacture of innovative cell therapies, like MB-105, and bring them into the clinic with a consistent and scalable manufacturing process,” said CTMC’s CEO, Jason Bock in a press release.

The partnership “has allowed us to move really quickly,” Hein says.

That’s because what CTMC does uniquely well is take early stage companies like March Biosciences and advance them to a state that’s ready for manufacturing in a short time, around 18 months, says Hein.

According to Hein, March Biosciences’ success is a testament to Houston and its world-class medical center.

“It’s a great example of the opportunities you see here in Houston, where we have a technology that was developed by brilliant scientists here in Houston and we can pull together the resources that we need to take it to the next level,” Hein says. "Working with partners here in Houston, we have all the pieces and the community rises to the occasion to support you.”

Houston innovator aims to scale cancer-curing cell therapies

HOUSTON INNOVATORS PODCAST EPISODE 185

It's almost unreal what can be done with therapeutics today, especially in the specialty of cell therapy.

"It feels like science fiction," says Jason Bock, founder and CEO of the Cell Therapy Manufacturing Center, or CTMC, a joint venture between National Resilience and MD Anderson Cancer Center.

Cell therapy is essentially personalized medicine, he explains. The process includes taking out a patient’s own immune cells, identifying specifically the T-cells, and engineer them to have them target cancer before expanding them and reintroducing them to the patient.

“The supply chain begins with the patient,” Bock explains on the Houston Innovators Podcast. “If the patient is going to be an integral part of the supply chain, one way to simplify your supply chain is to locate your manufacturing very close to where your patients are.”

That's where CTMC, located in the heart of the Texas Medical Center, comes in. Bock moved to Houston from the East Coast four years to stand up the program at MD Anderson. The founding thesis was to work with faculty members who have interesting ideas for biologics or cell therapies, help them industrialize them, and then bring them into the MD Anderson clinic to evaluate in patients.

Last year, the entity spun out into a joint venture structure with National Resilience, a company that was founded amid the pandemic to build resilience in the nation for complex biologics manufacturing — like vaccines, for instance — in order to expedite the process of getting these treatments to patients.

With access to patients established, how do you address scalability of this treatment in a field that's so customized?

While it might sound like a challenge to scale personalized medicine — it's a worthwhile challenge. Bock says that even though cell therapy is in its early stages still — the first treatment was approved by the FDA just five years ago — early studies have shown patients, who essentially have no other treatment options, can see life-saving results in as little as one treatment.

"We see in a large group of patients — 30 to 50 percent of patients — are cured with one dose," he says on the show.

CTMC has a 60,000-square-foot space two blocks away from MD Anderson. This critical lab space with 14 clean rooms was made available after its previous biotech tenant moved out. The setup can support up to 140 people, and the organization has grown to 80 people over the past few years.

Bock says CTMC is an engine for cell therapy research — one that can take a therapeutic from research to the clinic in about one to two years. Every year, he says CTMC can roll three to five therapeutics into the clinic phase.

And, Houston's an ideal place to do that.

"Houston has a chance to play a role in all aspects of cell therapy," he says, from discovery to the clinical side. "Some really interesting cell therapies that are in development were discovered here in Houston."

Bock shares more on how the impact CTMC is making on cell therapy advancement on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Houston cell therapy company launches second-phase clinical trial

fighting cancer

A Houston cell therapy company has dosed its first patient in a Phase 2 clinical trial. March Biosciences is testing the efficacy of MB-105, a CD5-targeted CAR-T cell therapy for patients with relapsed or refractory CD5-positive T-cell lymphoma.

Last year, InnovationMap reported that March Biosciences had closed its series A with a $28.4 million raise. Now, the company, co-founded by Sarah Hein, Max Mamonkin and Malcolm Brenner, is ready to enroll a total of 46 patients in its study of people with difficult-to-treat cancer.

The trial will be conducted at cancer centers around the United States, but the first dose took place locally, at The University of Texas MD Anderson Cancer Center. Dr. Swaminathan P. Iyer, a professor in the department of lymphoma/myeloma at MD Anderson, is leading the trial.

“This represents a significant milestone in advancing MB-105 as a potential treatment option for patients with T-cell lymphoma who currently face extremely limited therapeutic choices,” Hein, who serves as CEO, says. “CAR-T therapies have revolutionized the treatment of B-cell lymphomas and leukemias but have not successfully addressed the rarer T-cell lymphomas and leukemias. We are optimistic that this larger trial will further validate MB-105's potential to address the critical unmet needs of these patients and look forward to reporting our first clinical readouts.”

The Phase 1 trial showed promise for MB-105 in terms of both safety and efficacy. That means that potentially concerning side effects, including neurological events and cytokine release above grade 3, were not observed. Those results were published last year, noting lasting remissions.

In January 2025, MB-105 won an orphan drug designation from the FDA. That results in seven years of market exclusivity if the drug is approved, as well as development incentives along the way.

The trial is enrolling its single-arm, two-stage study on ClinicalTrials.gov. For patients with stubborn blood cancers, the drug is providing new hope.

Elon Musk's SpaceX site officially becomes the city of Starbase, Texas

Starbase, Texas

The South Texas home of Elon Musk’s SpaceX rocket company is now an official city with a galactic name: Starbase.

A vote Saturday, May 3, to formally organize Starbase as a city was approved by a lopsided margin among the small group of voters who live there and are mostly Musk’s employees at SpaceX. With all the votes in, the tally was 212 in favor to 6 against, according to results published online by the Cameron County Elections Department.

Musk celebrated in a post on his social platform, X, saying it is “now a real city!”

Starbase is the facility and launch site for the SpaceX rocket program that is under contract with the Department of Defense and NASA that hopes to send astronauts back to the moon and someday to Mars.

Musk first floated the idea of Starbase in 2021 and approval of the new city was all but certain. Of the 283 eligible voters in the area, most are believed to be Starbase workers.

The election victory was personal for Musk. The billionaire’s popularity has diminished since he became the chain-saw-wielding public face of President Donald Trump’s federal job and spending cuts, and profits at his Tesla car company have plummeted.

SpaceX has generally drawn widespread support from local officials for its jobs and investment in the area.

But the creation of an official company town has also drawn critics who worry it will expand Musk’s personal control over the area, with potential authority to close a popular beach and state park for launches.

Companion efforts to the city vote include bills in the state Legislature to shift that authority from the county to the new town’s mayor and city council.

All these measures come as SpaceX is asking federal authorities for permission to increase the number of South Texas launches from five to 25 a year.

The city at the southern tip of Texas near the Mexico border is only about 1.5 square miles (3.9 square kilometers), crisscrossed by a few roads and dappled with airstream trailers and modest midcentury homes.

SpaceX officials have said little about exactly why they want a company town and did not respond to emailed requests for comment.

“We need the ability to grow Starbase as a community,” Starbase General Manager Kathryn Lueders wrote to local officials in 2024 with the request to get the city issue on the ballot.

The letter said the company already manages roads and utilities, as well as “the provisions of schooling and medical care” for those living on the property.

SpaceX officials have told lawmakers that granting the city authority to close the beach would streamline launch operations. SpaceX rocket launches and engine tests, and even just moving certain equipment around the launch base, requires the closure of a local highway and access to Boca Chica State Park and Boca Chica Beach.

Critics say beach closure authority should stay with the county government, which represents a broader population that uses the beach and park. Cameron County Judge Eddie Trevino, Jr. has said the county has worked well with SpaceX and there is no need for change.

Another proposed bill would make it a Class B misdemeanor with up to 180 days in jail if someone doesn’t comply with an order to evacuate the beach.

The South Texas Environmental Justice Network, which has organized protests against the city vote and the beach access issue, held another demonstration Saturday that attracted dozens of people.

Josette Hinojosa, whose young daughter was building a sandcastle nearby, said she was taking part to try to ensure continued access to a beach her family has enjoyed for generations.

With SpaceX, Hinojosa said, “Some days it’s closed, and some days you get turned away."

Organizer Christopher Basaldú, a member of the Carrizo/Comecrudo Nation of Texas tribe, said his ancestors have long been in the area, where the Rio Grande meets the Gulf.

“It’s not just important,” he said, “it’s sacred.”

Texas-based 'DoorDash for laundry' startup tumbles into Houston market

No Scrubs

Laundry may seem like an endless task that piles up, but a new service offers a solution to overwhelmed Houston families.

NoScrubs, an Austin-based home laundry pickup service has just expanded to Houston. Described by the company as "DoorDash — but for laundry," they wash customer's clothes at local laundromats and return them the same day, folded and ready to be put away.

The service took off like gangbusters in Austin, making an expansion to the state's largest city an obvious choice. It's not universal coverage just yet.

For now, only the following ZIP codes have NoScrubs service available: 77002, 77004, 77005, 77006, 77007, 77008, 77009, 77010, 77018, 77019, 77024, 77025, 77027, 77046, 77056, 77057, 77081, 77098, 77401, 77030, 77003.

A single pickup starts at $40 for 20 pounds of laundry, while the basic monthly subscription is $60 for two pickups. All services use hypoallergenic detergents.

The average American family spends about 240 hours a year on laundry, making it a very time-consuming chore. For people with disabilities, difficult work schedules, and other circumstances, it can be a real help, says co-founder Matt O'Connor.

"Some of our favorite customer stories simply revolve around saving people time when they have something challenging going on," he writes in an email. "For example, one customer reviewed NoScrubs saying 'So happy I could cry! (Partially because I'm pregnant and my emotions are heightened!)...1000% recommend if you have time restrictions or physical restrictions! ' So, whether it’s saving time, the affordability, or the pleasantly surprising turnaround time, NoScrubs has a variety of benefits for any customer."

NoScrubs is also a new opportunity for Houston's gig workers. Because there are no passengers, it can be a safer alternative to driving ride share for women and other people apprehensive about having strangers in their cars. As NoScrubs partners with local laundromats, drivers are also going to centralized locations rather than all over the map, leading to less wear and tear on their cars. The laundromats benefit as well, since NoScrubs loads are ones that would otherwise be done at home.

"Our model makes driving a tiny fraction of the time, so folks who don’t want to wear down their vehicles and spend a ton on gas love working at NoScrubs," added O'Connor.
