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.

marching on

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.”

TMC cancer therapeutic accelerator names inaugural cohort

cancer innovation

The Texas Medical Center named 15 groundbreaking researchers and companies to its inaugural class of the Accelerator for Cancer Therapeutics on Thursday. All hail from the Lone Star State.

The ACT program is the only accelerator focused on cancer treatment at the earliest stages of commercialization, thanks to a $5 million grant from the Cancer Prevention and Research Institute of Texas awarded to the TMC in the fall of 2019.

The nine-month program kicked-off at the end of January and will be run by TMC Innovation, according to a release from the TMC. It aims to provide the class with resources to help their oncology biotech projects reach new milestones, including even commercialization.

The inaugural cohort is made up of companies and researchers exploring immunotherapy, cell therapy, targeted therapy, cancer pain, and drug platforms. The group is split about evenly between companies and academic researchers. The group of Texans includes:

  • Raptamer Discovery Group
  • IDA Therapeutics
  • Elbrus Therapeutics
  • Parthenon Therapeutics
  • Lokesh Battula
  • Aumeta
  • Autoimmunity Biologic Solutions
  • Max Mamonkin
  • Qing Yi
  • Astero Alta
  • TEZCAT Laboratories
  • Anil Sood
  • Coactigon
  • Xiadong Cheng
  • IonTx

At the end of the nine months, the class will present an integrated strategic plan and at least one grant submission. They will also have the opportunity to pitch investors and corporations.

The class will also gain support in grant writing, chemistry, and funding opportunities, as well as mentorship.

"As the past year has shown, the pace of scientific discovery can be blistering," says Tom Luby, director of TMC Innovation. "At the same time, successfully translating research into effective therapies available to patients requires a mix of business, technical and regulatory skills that may not typically be available to researchers.

"By linking the participants with mentors who can both advance their scientific work and support the technical needs, we expect this first class of ACT participants will make a meaningful difference for cancer patients in Texas and beyond."

TMCx, which is also run by TMC Innovation, recently announced seven health tech companies that were selected to its 2021 class of its health tech accelerator.

Broader in scope that the ACT accelerator, the TMCx startups focus on an array of subject matters from heart health to artificial intelligence to extremity rehabilitation.

Houston clocks in as one of the hardest working cities in America

Ranking It

Houston and its residents are proving their tenacity as some of the hardest working Americans in 2026, so says a new study.

WalletHub's annual "Hardest-Working Cities in America (2026)" report ranked Houston the 37th most hardworking city nationwide. H-town last appeared as the 28th most industrious American city in 2025, but it still remains among the top 50.

The personal finance website evaluated 116 U.S. cities based on 11 key indicators across "direct" and "indirect" work factors, such as an individual's average workweek hours, average commute times, employment rates, and more.

The U.S. cities that comprised the top five include Cheyenne, Wyoming (No. 1); Anchorage, Alaska (No. 2); Washington, D.C. (No. 2); Sioux Falls, South Dakota (No. 4); and Irving, Texas (No. 5). Dallas and Austin also earned a spot among the top 10, landing as No. 7 and No. 10, respectively.

Based on the report's findings, Houston has the No. 31-best "direct work factors" ranking in the nation, which analyzed residents' average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, the share of "engaged" workers, and the rate of "idle youth" (residents aged 16-24 that are not in school nor have a job).

However, Houston lagged behind in the "indirect work factors" ranking, landing at No. 77 out of all 116 cities in the report. "Indirect" work factors that were considered include residents' average commute times, the share of workers with multiple jobs, the share of residents who participate in local groups or organizations, annual volunteer hours, and residents' average leisure time spent per day.

Based on data from The Organisation for Economic Co-operation and Development (OECD), WalletHub said the average American employee works hundreds of more hours than workers residing in "several other industrialized nations."

"The typical American puts in 1,796 hours per year – 179 more than in Japan, 284 more than in the U.K., and 465 more than in Germany," the report's author wrote. "In recent years, the rise of remote work has, in some cases, extended work hours even further."

WalletHub also tracked the nation's lowest and highest employment rates based on the largest city in each state from 2009 to 2024.

Other Texas cities that earned spots on the list include Fort Worth (No. 13), Corpus Christi (No. 14), Arlington (No. 15), Plano (No. 17), Laredo (No. 22), Garland (No. 24), El Paso (No. 43), Lubbock (No. 46), and San Antonio (No. 61).

Data for this study was sourced from the U.S. Census Bureau, Bureau of Labor Statistics, U.S. Travel Association, Gallup, Social Science Research Council, and the Corporation for National & Community Service as of January 29, 2026.

With boost from Houston, Texas is the No. 1 state for economic development

governor's cup

Texas is on a 14-year winning streak as the top state for attracting job-creating business location and expansion projects.

Once again, Texas has claimed Site Selection magazine’s Governor’s Cup. This year’s honor recognizes the state with the highest number of economic development projects in 2025. Texas landed more than 1,400 projects last year.

Ron Starner, executive vice president of Site Selection, calls Texas “a dynasty in economic development.”

Among metro areas, Houston lands at No. 2 for the most economic development projects secured last year (590), behind No. 1 Chicago and ahead of No. 3 Dallas-Fort Worth.

In praising Houston as a project magnet, Gov. Greg Abbott cites the November announcement by pharmaceutical giant Lilly that it’s building a $6.5 billion manufacturing plant at Houston’s Generation Park.

“Growth in the Greater Houston region is a great benefit to our state’s economy, a major location for foreign direct investment and key industry sectors like energy, aerospace, advanced manufacturing, and life sciences,” Abbott tells Site Selection. “Houston is also home to one of the largest concentrations of U.S. headquarters for companies from around the world.”

In 2025, Fortune ranked Houston as the U.S. city with the third-highest number of Fortune 500 headquarters (26).

Texas retained the Governor’s Cup by gaining over 1,400 business location and expansion projects last year, representing more than $75 billion in capital investments and producing more than 42,000 new jobs.

Site Selection says Texas’ project count for 2025 handily beat second-place Illinois (680 projects) and third-place Ohio (467 projects). Texas’ number for 2025 represented 18% of all qualifying U.S. projects tracked by Site Selection.

“You can see that we are on a trajectory to ensure our economic diversification is going to inoculate us in good times, as well as bad times, to ensure our economy is still going to grow, still create new jobs, prosperity, and opportunities for Texans going forward,” Abbott says.
