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.”

Rice launches 'brain economy' initiative at World Economic Forum

brain health

Rice University has launched an initiative that will position “brain capital” as a key asset in the 21st century.

Rice rolled out the Global Brain Economy Initiative on Jan. 21 at the World Economic Forum in Davos, Switzerland.

“This initiative positions brain capital, or brain health and brain skills, at the forefront of global economic development, particularly in the age of artificial intelligence,” the university said in a news release.

The Rice-based initiative, whose partners are the University of Texas Medical Branch in Galveston and the Davos Alzheimer’s Collaborative, aligns with a recent World Economic Forum and McKinsey Health Institute report titled “The Human Advantage: Stronger Brains in the Age of AI,” co-authored by Rice researcher Harris Eyre. Eyre is leading the initiative.

“With an aging population and the rapid transformation of work and society driven by AI, the urgency has never been greater to focus on brain health and build adaptable human skills—both to support people and communities and to ensure long-term economic stability,” says Amy Dittmar, a Rice provost and executive vice president for academic affairs.

This initiative works closely with the recently launched Rice Brain Institute.

In its first year, the initiative will establish a global brain research agenda, piloting brain economy strategies in certain regions, and introducing a framework to guide financial backers and leaders. It will also advocate for public policies tied to the brain economy.

The report from the McKinsey Health Institute and World Economic Forum estimates that advancements in brain health could generate $6.2 trillion in economic gains by 2050.

“Stronger brains build stronger societies,” Eyre says. “When we invest in brain health and brain skills, we contribute to long-term growth, resilience, and shared prosperity.”

Rice Alliance and the Ion leader Brad Burke to retire this summer

lasting legacy

Brad Burke—a Rice University associate vice president who leads the Ion District’s Rice Alliance for Technology and Entrepreneurship and is a prominent figure in Houston’s startup community—is retiring this summer after a 25-year career at the university.

Burke will remain at the Rice Alliance as an adviser until his retirement on June 30.

“Brad’s impact on Rice extends far beyond any single program or initiative. He grew the Rice Alliance from a promising campus initiative into one of the most respected university-based entrepreneurship platforms,” Rice President Reginald DesRoches said in a news release.

During Burke’s tenure, the Rice Business School went from unranked in entrepreneurship to The Princeton Review’s No. 1 graduate entrepreneurship program for the past seven years and a top 20 entrepreneurship program in U.S. News & World Report’s rankings for the past 14 years.

“Brad didn’t just build programs — he built an ecosystem, a culture, and a reputation for Rice that now resonates around the world,” said Peter Rodriguez, dean of the business school. “Through his vision and steady leadership, Rice became a place where founders are taken seriously, ideas are rigorously supported, and entrepreneurship is embedded in the fabric of the university.”

One of Burke’s notable achievements at Rice is the creation of the Rice Business Plan Competition. During his tenure, the competition has grown from nine student teams competing for $10,000 into the world’s largest intercollegiate competition for student-led startups. Today, the annual competition welcomes 42 student-led startups that vie for more than $1 million in prizes.

Away from Rice, Burke has played a key role in cultivating entrepreneurship in the energy sector: He helped establish the Energy Tech Venture Forum along with Houston Energy and Climate Startup Week.

Furthermore, Burke co-founded the Texas University Network for Innovation and Entrepreneurship in 2008 to bolster the entrepreneurship programs at every university in Texas. In 2016, the Rice Alliance assumed leadership of the Global Consortium of Entrepreneurship Centers.

In 2023, Burke received the Trailblazer Award at the 2023 Houston Innovation Awards and was recognized by the Deshpande Foundation for his contributions to innovation and entrepreneurship in higher education.

“Working with an amazing team to build the entrepreneurial ecosystem at Rice, in Houston, and beyond has been the privilege of my career,” Burke said in the release. “It has been extremely gratifying to hear entrepreneurs say our efforts changed their lives, while bringing new innovations to market. The organization is well-positioned to help drive exponential growth across startups, investors, and the entrepreneurial ecosystem.”

Starting April 15, John “JR” Reale Jr. will serve as interim associate vice president at Rice and executive director of the Rice Alliance. He is managing director of the alliance. Reale is co-founder of the Station Houston startup hub and a startup investor. He was also recently named director for startups and investor engagement at the Ion.

“The Rice Alliance has always been about helping founders gain advantages to realize their visions,” Reale said. “Under Brad’s leadership, the Rice Alliance has become a globally recognized platform that is grounded in trust and drives transformational founder outcomes. My commitment is to honor what Brad has built and led while continuing to serve our team and community, deepen relationships and deliver impact.”

Burke joined the Houston Innovators Podcast back in 2022. Listen to the full interview here.

Houston team uses CPRIT funding to develop nanodrug for cancer immunotherapy

cancer research

With a relative five-year survival rate of 50 percent, pancreatic cancer is a diagnosis nobody wants. At 60 percent, the prognosis for lung cancer isn’t much rosier. That’s because both cancers contain regulatory B cells (Bregs), which block the body’s natural immunity, making it harder to fight the enemies within.

Newly popular immunotherapies in a category known as STING agonists may stimulate natural cancer defenses. However, they can also increase Bregs while simultaneously causing significant side effects. But Wei Gao, assistant professor of pharmacology at the University of Houston College of Pharmacy, may have a solution to that conundrum.

Gao and her team have developed Nano-273, a dual-function drug, packaged in an albumin-based particle, that boosts the immune system to help it better fight pancreatic and lung cancers. Gao’s lab recently received a $900,000 grant from the Cancer Prevention and Research Institute of Texas (CPRIT) to aid in fueling her research into the nanodrug.

“Nano-273 both activates STING and blocks PI3Kγ—a pathway that drives Breg expansion, while albumin nanoparticles help deliver the drug directly to immune cells, reducing unwanted side effects,” Gao said in a press release. “This approach reduces harmful Bregs while boosting immune cells that attack cancer, leading to stronger and more targeted anti-tumor responses.”

In studies using models of both pancreatic and lung cancers, Nano-273 has shown great promise with low toxicity. Its best results thus far have involved using the drug in combination with immunotherapy or chemotherapy.

With the CPRIT funds, Gao and her team will be able to charge closer to clinical use with a series of important steps. Those include continuing to test Nano-273 alongside other drugs, including immune checkpoint inhibitors. Safety studies will follow, but with future patients in mind, Gao will also work toward improving her drug’s production, making sure that it’s safe and high-quality every time, so that it is eventually ready for trials.

Gao added: “If successful, this project could lead to a new type of immunotherapy that offers lasting tumor control and improved survival for patients with pancreatic and lung cancers, two diseases that urgently need better treatments."
