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.”

Texas voters OK $3 billion for new dementia research institute

state funding

Texas voters on Nov. 4 overwhelmingly approved a ballot measure that provides $3 billion in state funding over a 10-year span for the newly established Dementia Prevention and Research Institute of Texas (DPRIT).

Thanks to the passage of Proposition 14, Texas now boasts the country’s largest state-funded initiative dedicated to dementia research and prevention, according to the Alzheimer’s Association. Up to $300 million in grants will be awarded during the 10-year funding period.

“This is a transformative moment for Texas and for the fight against Alzheimer’s and all other dementia,” said Joanne Pike, president and CEO of the Alzheimer’s Association. “Texans have chosen to invest in hope, innovation, and solutions for the millions of families affected by these devastating diseases. With the passage of Proposition 14, Texas is now poised to lead the nation in dementia research and prevention.”

The association says DPRIT will drive scientific breakthroughs, attract top-notch dementia researchers to Texas, and generate thousands of jobs statewide.

An estimated 460,000 Texans are living with dementia, the association says, and more than one million caregivers support them.

DPRIT is modeled after the Cancer Prevention and Research Institute of Texas (CPRIT). Since 2008, the state agency has awarded nearly $4 billion in grants to research organizations for cancer-related academic research, prevention programs, and product development.

An analysis by the McKinsey Health Institute found that investing in brain health initiatives like DPRIT could boost Texas’ GDP by $260 billion. Much of that GDP bump could benefit the Houston area, which is home to dementia-focused organizations such as UTHealth Houston Neurosciences, Baylor College of Medicine’s Center for Alzheimer’s and Neurodegenerative Diseases, the University of Texas Medical Branch at Galveston’s Collaborative Alzheimer’s Disease and Memory Disorders Program, and the Houston Methodist Research Institute’s John M. O’Quinn Foundation Neurodegenerative Disorders Laboratory.

The Greater Houston Partnership says DPRIT holds the potential “to elevate Texas — particularly Houston — as a hub for brain health research.”

State Sen. Joan Huffman, a Houston Republican, is one of DPRIT’s champions. She sponsored legislation this year to create the institute and ask Texas voters to approve the $3 billion in funding.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said in May. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our health care community.”

Houston Innovation Awards to honor Wade Pinder as 2025 Trailblazer

And the award goes to...

On Nov. 13, we'll gather for the 2025 Houston Innovation Awards to celebrate the best and brightest in Houston innovation right now. And, as is tradition with the annual program, we'll honor one longstanding Houston innovator with the Trailblazer Award.

The award was established to recognize an individual who has left a profound impact on Houston's business and innovation ecosystem and is dedicated to continuing to support Houston and its entrepreneurs. The recipient is selected by our esteemed panel of judges from a pool of internal and external recommendations.

The 2025 Trailblazer Award recipient is Wade Pinder of Product Houston. A familiar face to those active in Houston's innovation sector, Pinder identifies as an "Ecosystem Wayseeker" and is the founder of Product Houston.

Pinder, a former product manager at Blinds.com, arrived in Houston in 2008 and has been deeply engaged in Houston’s startup and innovation scene since 2012. Over the years, he has supported hundreds of founders, product leaders, and community builders across the Houston area.

In 2023, he was honored as Mentor of the Year in the Houston Innovation Awards. Today, he fosters collaboration, clarity, and connection through his work at Product Houston, and he helps innovators find their place in the local sector via his monthly "Houston Ecosystem Mapping" sessions.

Read below for Pinder's insightful takes on the Houston innovation scene and what it means to blaze a new trail. Then, join us as we celebrate Pinder and all of our nominees and winners at the 2025 Houston Innovation Awards on Nov. 13 at Greentown Labs. Tickets are available now.

InnovationMap: Describe the growth of the Houston innovation ecosystem from your arrival in 2008 to now.

Wade Pinder: When I first arrived in Houston in 2008, the innovation ecosystem was more fragmented than it is today. Connecting with other innovators often meant attending a lot of hit-or-miss events. Over the years, it’s been incredible to see the network take shape and grow into a true community. I’ve had the privilege of being involved with several coworking spaces and accelerator programs along the way, and it’s been especially exciting to see Station Houston evolve into what is now the Ion District. What makes the Ion unique is how it blends openness and opportunity… ideas spill into and out of the space, and anyone can walk in, participate in programming, and find themselves in proximity to people who might help them take the next steps.

Additionally, the expansion of spaces like Texas Medical Center Innovation, Helix Park, The Cannon, and many others, have broadened Houston’s innovation landscape in powerful ways.

Today, when someone new moves to Houston and wants to plug into the startup and innovation scene, it’s much easier for them to find their way than when I moved here in 2008. I think that’s something Houston can really be proud of.

IM: As someone who engages with the broader Houston innovation community on a regular basis, what are the shared characteristics and traits that you see among its members?

WP: One of the things that makes Houston’s innovation community unique is how deeply it’s rooted in industry. So many of the innovators I meet come from within Houston’s major sectors, and they’ve seen firsthand where opportunities lie, which gives their innovation a certain practicality. They’re developing solutions that solve real, often complex, business and industry problems, not chasing trends or trying to create the next flashy consumer app.

What I admire most is that this community is growing in its understanding of the value of collaboration. They work with the systems and expertise that already exist, and find better ways to make them work together. Another shared trait I see across Houston’s innovators is a deep sense of curiosity and a drive to question the status quo while looking for better ways to build, improve, and solve.

IM: You’ve said, "Houston has Houston problems, and Houston needs Houston solutions." How do you see this taking shape in the innovation sector right now?

WP: When I first started getting connected to Houston’s startup and innovation scene in 2012, I noticed folks had a tendency to look at other cities and ask, "How can we do what they did?" Back then, we saw phrases like "Silicon Bayou" pop up, and while that enthusiasm was hopeful, it often discounted the things that make Houston unique. Over time, I’ve come to believe that the better question is: "What are we already great at, and how can we innovate from there?" The flip side of that question is to reflect on the things that hold us back as an ecosystem… identifying the friction points and finding practical ways to smooth them out.

From my time wandering around our ecosystem, I’ve come to understand Houston is great at infrastructure at scale, solving life-and-death challenges in the global spotlight, and "boldly going where no one’s gone before." These three things, in my opinion, capture the essence of Houston does best: We do hard things here.

What excites me today is that we’re applying innovation to those core strengths in ways that feel authentically Houston. One area I’m especially excited about is the emergence of the “New Space Economy,” captured beautifully in Wogbe Ofori’s thought piece “The Astropreneur’s Startup Journey Map.” It's a great example of how the next wave of space-related innovation might connect to Houston’s long-standing strengths in manufacturing, logistics, and problem-solving at scale.

Another challenge Houston faces is what I call a "proximity problem." Even when events are only a few miles apart, traffic can make it difficult for people to stay connected across the city. That’s why I’m so encouraged by the rise of what I think of as "intent-based gatherings" around the city: events designed with purpose, where people know they’ll find real connection and value once they arrive.

IM: Finally, what does being a "Trailblazer" mean to you?
WP: To me, trailblazing in the Houston innovation ecosystem means being willing to wander through the many different corners of the community and look for value in places we often overlook. It’s about showing up at events, community meetings, and pitch competitions — not just to participate, but to notice how each of these "nodes" in the ecosystem connects and adds value to the others.

Sometimes the trailblazer only walks a trail once: as they are discovering it. If you can help others see a newfound trail’s purpose and potential, it becomes a path others can follow more easily in the future. That’s the real work of a trailblazer: mapping connections, framing their value, and helping people recognize how those pathways strengthen the ecosystem as a whole.

In a broader sense, trailblazing is about seeing things not just as they are, but as they could be. Then taking the steps, however small, that make that vision real.
