When cancer originates in a patient, their body fights as hard as it can against the disease, but sometimes, the cancer wins the battle. However, one Houston cell therapy startup is working on an artillery of therapeutics to help arm patients' bodies to win the war.

Founded in 2022, March Biosciences is a cell therapy company born in part out of the Texas Medical Center's Accelerator for Cancer Therapeutics, where Sarah Hein served as inaugural entrepreneur in residence. In that role, she met her co-founders Max Mamonkin and Malcolm Brenner.

Now, leading the startup as CEO, Hein tells the Houston Innovators Podcast that with March's lead product, MB-105, an autologous CD5 CAR T cell therapy, the name of the game is to zero in on advancing this particular treatment to its phase II trial next year.

"Targeted therapies are targeted. Our target is expressed on these T-cell cancers, and there are a couple other cancers, like Mantle Cell Lymphoma or Chronic Lymphocytic Leukemia," Hein says on the show. "Unfortunately, I don't think there's ever going to be a magic bullet that is going to hit a huge swath of these cancers. We're going to continue to chip away at these cancers by creating really elegantly engineered therapies against these different kinds of tumors.

"March, in general, is committed to this idea that we're going to continue to work on difficult tumors and different targets with our uniquely engineered targeting strategy against these diseases. As we expand into the next year, you'll see us speak on this a little more on how we're going to continue to work on new diseases that havent been addressed previously," she continues.

Hein explains how March Biosciences — named in part as a nod to one of Houston's best months weather wise — has benefitted from the support of the local life science community. Last year, March announced its partnership with CTMC (Cell Therapy Manufacturing Center), a joint venture between MD Anderson Cancer Center and National Resilience. Hein says over the past year, they've moved into CTMC and that's allowed them to accelerate their progress as a company.

"Houston has a unique sophistication in cell therapy. Where we've had biotech spinout, cell therapy has been one of our more successful verticals," she says. "We've had resources and knowledge here that were uniquely available for our drug category."

Earlier this month, March Biosciences announced an oversubscribed $28.4 million series A led by Mission BioCapital and 4BIO Capital and bringing the company's total funding secured to more than $51 million, including its prestigious CPRIT grant. Hein says this funding will go toward further developing March's therapeutics and team as it gears up for its phase II trial next year.

Ultimately, Hein explains on the show how passionate she is and her team is on continuing to develop treatments to fight cancer with their targeted approach.

"I never have to explain to people why we would go out and fight cancer. I think it's a self-evident hypothesis," she says. "But what I personally find is exciting in cancer therapies in general are these immune therapies, where you using the body's own immune system to seek out and destroy the cancer cells.

"What's really exciting about that is these are the same immune cells that fight cancer or pre-cancers for most of your life and usually what happens is the cancers figure out a way to mass themselves. With modern approaches, we can boost the immune system."

Clinical-stage Houston cell therapy company closes $28.4M oversubscribed series A

cha-ching

An emerging biotech company in Houston has closed its series A with outsized success.

March Biosciences' oversubscribed raise brought in $28.4 million of financing with Mission BioCapital and 4BIO Capital leading the pack of investors. The company has now raised more than $51 million in total.

Last year, March Biosciences announced its strategic alliance with CTMC (Cell Therapy Manufacturing Center), a joint venture between MD Anderson Cancer Center and National Resilience. CEO Sarah Hein met her co-founder, Max Mamonkin, at the TMC Accelerator for Cancer Therapeutics. Along with fellow co-founder Malcolm Brenner, March Biosciences launched from the Center for Cell and Gene Therapy (Baylor College of Medicine, Houston Methodist Hospital and Texas Children’s Hospital). Its goal is to fight cancers that have been unresponsive to existing immunotherapies using its lead asset, MB-105.

An autologous CD5-targeted CAR-T cell therapy, MB-105 is currently in phase-1 trials in patients with refractory T-cell lymphoma and leukemia. The treatment is showing signs of being both safe and effective, meriting a phase-2 trial that will begin early next year. The funds raised from the series A will help to finance the Phase 2 clinical development of MB-105 to expand on the existing data with optimized manufacturing processes.

“This oversubscribed financing enables us to advance our first-in-class CAR-T therapy, MB-105, into a Phase 2 trial for T-cell lymphoma – an indication with an exceptionally poor prognosis and few treatment options,” says Hein. “With the support and confidence of our investors, we are not only advancing our lead program but also expanding our pipeline, underscoring our commitment to delivering best-in-class therapies to patients that can change the treatment paradigm for these challenging cancers.”

But that’s not the only exciting news that Hein and her associates have to report. March Biosciences has recently partnered with cell therapy venture studio, Volnay Therapeutics. Led by highly experienced cell therapy development veterans, the March Biosciences team will work to develop a scalable manufacturing process for MB-105 that will lead to commercialization. Volnay co-founder and CEO Stefan Wildt, who held key R&D leadership positions in cell and gene therapy units at Novartis and Takeda, has also joined the board of March Biosciences. The board of directors is also welcoming Cassidy Blundell of Mission BioCapital and Owen Smith of 4BIO Capital.

“The team at March Biosciences is leveraging powerful science and promising clinical data to tackle cancers with significant unmet need,” says Blundell, a partner at Mission BioCapital. “We're excited to support their journey and believe their focused approach with MB-105 could lead to significant breakthroughs in the CAR-T space.”

The Houston-born company, which is a finalist for the 2024 Houston Innovation Awards, continues to accelerate quickly, in part thanks to its home base. After all, existing local investors like TMC Venture Fund also participated in the new raise. As Hein said last year, “Working with partners here in Houston, we have all the pieces and the community rises to the occasion to support you.”

Port Houston reports emissions progress as cargo volumes climb

Greener growth

Port Houston’s initiatives to reduce emissions have shown some positive results, according to new data from the Port of Houston Authority.

Pulling from the Goods Movement Emissions Inventory (GMEI) report, which tracks port-related air emissions, Port Houston cited several improvements compared to the most recent report from 2019.

The port has seen total tonnage and container volumes increase by 16 percent and 28 percent, respectively, since 2019. However, greenhouse gas emissions have increased at a slower rate, growing only by 10 percent during the same time period, according to the data.

Additionally, emissions of nitrogen oxide fell by 7 percent, and emissions of particulate matter fell by 4 percent, despite adding 280 more pieces of cargo handling equipment.

“These results show that our emission-reduction efforts are working, and we are moving in the right direction,” Chairman Ric Campo said in a news release.

The Port Commission also recently approved items related to the $3 million U.S. Environmental Protection Agency Clean Ports Program (CPP) grant, which it received last year. The items will allow the port to work towards five new sustainability initiatives.

They include:

  1. An inventory of the port’s Scopes 1, 2, and 3 for greenhouse gas emissions
  2. A Port Area Climate Action Plan for the area and surrounding communities
  3. A CPP Truck Route Analysis
  4. Creation of the CPP Trucking Industry Collaborative
  5. Design of a customized website for Port of Houston Partners in Maritime Education, which is a non-profit leading maritime workforce development effort in local schools

Port Houston aims to be carbon neutral by 2050.

Houston leader on building inclusive communities through innovation

Guest Column

Innovation is often celebrated for speed or curiosity, but genuine progress is about inclusion and expanding the populations that benefit from new technologies.

For example, at Yale University, nursing students are now utilizing a hyper-realistic patient mannequin with Down syndrome, which not only mimics appearance but also fosters both empathy and competence in medical professionals who will treat people of all abilities. Tools like this remind us that innovation is not only about what is new, but also about how we include everyone in progress.

Inclusive Technology: What It Means

Inclusive technology design begins with diverse users in mind, including people living with disabilities such as blindness, hearing loss, or limb loss. Additionally, neurodiverse learners and those with varied learning styles benefit from inclusive technology. The purpose is to create tools that serve everyone in their homes, classrooms, workplaces, and public spaces. Inclusive technology is not only about empathy, but also equity. Innovation bridges gaps and extends access to all people.

National and Local Innovations Advancing Inclusion

Across the country, inclusive technology is transforming access for individuals with varying abilities. Robotics adapted for visually impaired students, audio-virtual reality labs for immersive learning, and AI-based platforms that personalize lessons for students are helping students engage in ways traditional tools cannot. These innovations are not just technical; instead, they are also deeply human, designed to expand access and opportunity for every learner.

Locally, Houston-based organizations demonstrate how inclusive tech can be paired with supportive programs to amplify impact:

  • BridgingApps, a program of Easter Seals of Greater Houston, provides assistive-tech labs and mobile devices for children and adults with disabilities, helping students communicate, learn, and connect in ways they may not have thought possible before.
  • MADE Houston creates adaptive classroom environments for twice-exceptional learners (gifted students with learning differences), ensuring that both their strengths and challenges are incorporated in the curriculum and class experiences.

Both programs partner with Camp For All to provide barrier-free camp experiences to their students.

Innovative technology has the power to change student outcomes and improve the quality of life. Reports such as Inclusive Technology in a 21st Century Learning System show that students with disabilities who have access to these tools are two to three times more likely to graduate from high school than those without.

Complementing these technology-driven advances are experiential programs that create community and empowering experiences.

Camp For All, for example, offers medically safe and adaptive camp experiences for children and adults with challenging illnesses, disabilities, or special needs. Camp For All demonstrates how barrier-free environments, combined with opportunities to explore and try new activities, foster confidence and resilience in campers, such as those who benefit from Easter Seals of Greater Houston and MADE Houston camps.

Why This Matters

When tools and technologies are designed to include everyone, the impact has the potential to impact all people. Individuals with physical, sensory, or learning differences gain confidence and access to opportunities, which leads to more diverse workforces and stronger communities.

Technology, educational tools, and thoughtfully designed programs can reduce barriers, improve academic outcomes, and help prepare individuals for future employment and independent living. Conversely, failing to design inclusively can further entrench inequities related to race, income, and abilities.

For context, while the national graduation rate for students with disabilities has risen to 74%, it still lags behind the 88% rate for peers without disabilities. Technology and inclusive programs help bridge this gap, ensuring that not only more students graduate, but that individuals with disabilities also are better prepared to access higher education, participate fully in the workforce, and engage in social and civic life.

Inclusive tools, such as accessible transportation services, audible pedestrian signals, braille ballots for voting, and short-term device loan programs like TTAP, expand opportunities and promote equitable participation across all aspects of society.

Additionally, research shows that early exposure and inclusion of those living with disabilities, such as in classrooms, community spaces, and club activities, fosters a greater acceptance of differences and proclivity toward inclusive attitudes as children mature. When we begin focusing on acceptance and innovative solutions for all people from the very beginning, our communities are stronger and we increase access to participation for all.

Challenges, Opportunities, and Ripple Effects

Despite progress, obstacles to scaling inclusive technology remain. Many families and schools cannot afford high-end assistive devices, and tools are often developed without input from the users who will rely on them the most.

Although grants and pilot programs exist, systemic funding and support are still limited. Educators, healthcare providers, and city planners also require training and guidance to effectively implement these tools. Overcoming these challenges requires coordinated efforts among technology companies, educators, nonprofits, policymakers, and the communities they serve.

Houston’s rich mix of innovation, research institutions, and nonprofit networks makes it an ideal testing ground for inclusive technology, and we are seeing more advancements daily. Schools and early learning centers are piloting innovative tools, including adaptive learning software, interactive robotics, music therapy, and word prediction programs.

At the same time, medical and therapy programs use simulation labs and telehealth tools to improve treatment for children and adults with disabilities. Civic and public spaces are also becoming more accessible through smart city initiatives such as wayfinding apps, inclusive playgrounds, and sensory-friendly public areas. These examples demonstrate that inclusive technology is about creating meaningful opportunities for everyone, regardless of ability, background, or resources.

When inclusion is prioritized, the benefits extend far beyond individual users. Educational outcomes improve as more students meet learning goals and graduate successfully. Workforce readiness increases as a broader range of skills and abilities enters the labor market. Community equity grows as individuals from underserved communities gain access to tools and experiences that were previously inaccessible.

Increasing participation for students and individuals translates into stronger local and state economies. At its core, inclusive technology creates equity and resilience at both the individual and community level.

Moving Forward

Designing with empathy, investing in equitable access, and acting with urgency are essential to building communities where everyone has the opportunity to contribute. Houston, with its combination of medical research institutions, ed-tech startups, aerospace leadership, nonprofit networks, and pilot programs, is uniquely positioned to lead the nation in inclusive innovation.

By prioritizing technology and programs that serve all learners, the city can demonstrate that meaningful progress is measured not by speed or novelty, but by the number of people who benefit from it. When cities, organizations, and communities commit to inclusive design, they build stronger and more equitable places where everyone benefits and thrives.
