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."

Houston program buoys promising cancer research with live-saving innovation

act-ing now

How do you bring promising cancer research to the masses? TMC Innovation's Accelerator for Cancer Therapeutics was established with that question in mind.

Funded by a $5 million grant from CPRIT, or the Cancer Prevention and Research Institute of Texas, in 2019 and in collaboration with the Gulf Coast Consortia and the University of Texas Medical Branch, the first cohort began their intensive work in 2021. The deadline to join the next cohort is October 13.

Since its inception, ACT has seen the forming of 19 companies — two of which have been awarded CPRIT seed grants, along with four in contention for one this year — as well as $92 million in dilutive funding and $10 million in non-dilutive funding.

“We’ve recruited investigators and companies from the breadth and width of the state of Texas, so all the way from Lubbock to Galveston from Dallas to the Rio Grande Valley,” Ahmed AlRawi, program manager, tells InnovationMap. “We've had an amazing set of investigators who have gone through the program — 56 teams to be precise.”

AlRawi says that the first pillar of the program is education. To that end, the cohort works with entrepreneurs in residence like Michael Torres. Best known as the co-founder of ReCode Therapeutics, Torres says that one of his greatest passions lies in translating science into medicines. ReCode is a genetic medicines company that is currently clinical-stage. It’s raised more than $300 million in the last two years, certainly something to which scientist-entrepreneurs earlier in their careers would aspire.

A longtime resident of Dallas, Torres moved his family to Houston last year, calling it “the place to be for cancer startups in Texas.”

Initially, says Torres, Houston wasn’t on his radar. But thanks to a call from ACT external advisor Dan Hargrove, Torres realized that the city might be a fit for him and his goals.

“I wanted to find a project that I could help support, sort of take my experience as a cofounder and help guide the next great startup within the ecosystem,” he says.

Torres and AlRawi agree that the biggest successes to come out of ACT so far include March Biosciences, a company from the first cohort, which is focused on developing CAR-T cell strategies to help combat hematological cancers; CPRIT fundee, OmniNano Pharmaceuticals, which uses patented nanotechnology to co-deliver a pair of therapeutical agents to solid tumors; and the latest, CrossBridge Bio.

Part of the most recent cohort, Torres has joined Drs. Kyoji Tsuchikama and Zhiqiang An as the last company’s CEO. To that end, he’s partnered with the world-class researchers out of UT Health Houston to build a next-generation antibody drug conjugate company that he believes will produce “better and safer and more effective drugs than what's currently on the market today.”

All the more reason that Torres he’s glad to have moved to Houston at what he calls “a really exciting time.” He’s thankful for the Texas Medical Center and the relationships it fosters. “We're all sort of aligning on creating a sustainable biotech ecosystem,” he says. And the next big cancer fighting company may well emerge from ACT.

Houston immunotherapy company to use $13.5M grant to further develop cancer treatments

future of pharma

Between Bangalore and Chennai in the Indian state of Andhra Pradesh, you’ll find the town of Tirupati. It’s home to seven peaks that host a Hindu temple complex devoted to a form of Vishnu, Venkateshvara. It is also the region from which Upendra Marathi originally hails. It’s where his father, and many other family members, attended medical school.

“My father’s first job was to take care of the pilgrims,” recalls Marathi.

It's only natural that his groundbreaking Houston company would be named 7 Hills Pharma.

“That sort of selflessness and giving back, I wanted to embody it in the name of the company,” Marathi says.

Now, 7 Hills Pharma is announcing that last month, it was awarded a $13.5 million grant from the Cancer Prevention and Research Institute of Texas (CPRIT). That’s on top of more than $13 million in NIH grants, making the company the second largest recipient of SBIR/STTR grants in Texas.

Launched in 2016, 7 Hills Pharma is working to develop drugs that can overcome the all-too-common problem of immunotherapy resistance. Thanks to the Nobel Prize-winning work of Jim Allison in the realm of immuno-oncology, the field was “very hot” at the time, says Marathi, particularly in Houston.

So what has 7 Hills developed? Oral small molecules that activate integrins — the receptors that allow cells to bind to one another — allowing for the cell-to-cell interactions that create a successful immune response to immune checkpoint inhibitors such as Yervoy. In other words, they have created capsules that increase the effectiveness of drugs that allow the body’s own immune response to fight cancers.

But that’s not all. Tests have shown that the same discovery, called alintegimod, can also augment the effectiveness of vaccines. The pill, which co-founder and co-inventor Peter Vanderslice calls “a beautiful way to amplify the vaccines,” can potentially be applied to anything from influenza to coronavirus.

Their greatest challenge, says Vanderslice, is the very fact that the technology is so novel.

“Most large pharmas are very risk averse,” he explains. “They only want to do ‘me-too’ kinds of drugs.”

7 Hills Pharma is the third company Marathi, both a PhD and an MBA, has helped to found based on technology he co-invented. Vanderslice is director of the molecular cardiology research laboratories at The Texas Heart Institute.

“It’s very much a homegrown company,” Marathi says.

And a small one, at least for now. Working out of JLabs@TMC, the full-time team is currently just Marathi and Siddhartha De, the senior director of development. Marathi convinced De to transplant himself and his family from India for the purpose of assisting 7 Hills with preparing its drugs for clinical readiness.

The CPRIT funds will allow 7 Hills Pharma to hire several long-time team members full-time and with benefits.

“The bringing of talent and bringing of technology to TMC and what was born at Texas Heart Institute is rather remarkable,” says Rob Bent, the company’s director of operations.

The next step for 7 Hills Pharma is a Phase Ib/IIa clinical trial in patients with treatment-resistant solid tumors. And the team just finalized the deck that will help raise another $10 million to $250 million in the company’s series A. And hopefully sooner rather than later, a new set of medical pilgrims will be thanking 7 Hill Pharma for its care.

Pharma giant considers Houston for $1B manufacturing campus

in the works

Another pharmaceutical giant is considering Houston’s Generation Park for a manufacturing hub.

According to a recent filing with the Texas Jobs, Energy, Technology and Innovation (JETI) program, Bristol Myers Squibb Co. is considering the northeast Houston management district for a new $1 billion multi-modal pharmaceutical manufacturing campus.

If approved, the campus, known as Project Argonaut, could create 489 jobs in Texas by 2031. Jobs would include operations technicians, engineering roles, administrative and management roles, production specialists, maintenance support, and quality control/assurance. The company predicts annual average wages for these positions to be around $96,000, according to the filing.

The project currently includes the 600,000-square-foot facility, but according to the filing, Bristol Myers Squibb “envisions this site growing in scale and capability well beyond its opening configuration."

The Texas JETI program offers companies temporary school property tax limitations in exchange for major capital investment and job creation. E.R. Squibb & Sons LLC applied for a 10-year tax abatement agreement in the Sheldon Independent School District.

The agreement promises a $ 1 billion investment. Construction would begin in 2027 and wrap in 2029.

“The proposed project reflects [Bristol Myers Squibb Co.’s] enduring commitment to bringing innovative medicines to patients and ensuring the long-term supply reliability they depend on,” the filing says. “The proposed project is purpose-built to support and manufacture medicines spanning multiple therapeutic areas and modalities, positioning the site as a long-term launch and commercial campus for decades to come. These medicines will provide therapies to the [Bristol Myers Squibb Co.’s] patients located in markets both nationally and internationally.”

The Fortune 100 company is considering 16 other cities for the new manufacturing facility in the Central and Eastern markets in the U.S. According to the Houston Chronicle, Bristol Myers Squibb Co is still in the “evaluation process” for its potential manufacturing site.

Last fall, Eli Lilly and Co. selected Generation Park for its $6.5 billion manufacturing plant. More than 300 locations in the U.S. competed for the factory. Read more here.

Houston health tech co. lands NIH grant for AI cancer prediction tool

fresh funding

Houston-based CellChorus and Stanford Medicine were recently awarded a Phase I Small Business Innovation Research grant for the company's AI platform to test how certain cancer patients will respond to therapies.

The funding comes from the National Cancer Institute of the National Institutes of Health. According to a filing, the grant totaled just under $400,000.

CellChorus, which spun out from the University of Houston’s Technology Bridge, has developed TIMING (Time-lapse Imaging Microscopy In Nanowell Grids), which analyzes the behavior of thousands of individual immune cells over time and can identify early indicators of treatment success or failure.

The company will work with Stanford's Dr. David Miklos and Dr. Saurabh Dahiya, who have built the Bone Marrow Transplantation and Cell Therapy Biobank. The biobank manages and stores biological samples from patients treated at their clinic and in clinical trials.

"Predicting which patients will achieve durable responses after CAR-T therapy remains one of the most important challenges in the field,” Miklos said in a news release. “We aim to uncover functional cellular signatures that can guide treatment decisions and improve patient outcomes.”

The project will specifically profile cells from patients with relapsed/refractory large B-cell lymphoma (r/rLBCL). According to CellChorus, only about half of r/rLBCL patients who receive CAR-T therapy "achieve a durable, long-term remission." Others do not respond to therapy or experience relapse.

“The sooner we know whether a cancer therapy is working, the better. To maximize patient benefit, we need technology that can provide a robust and early prediction of response to therapy. The technology needs to be scalable, cost-efficient, and capable of rapid turnaround times,” Rebecca Berdeaux, chief scientific officer of CellChorus, added in the release. “We are excited to work with Drs. David Miklos and Saurabh Dahiya and their colleagues on this very important project.”

CellChorus has previously received SBIR grants from federal agencies, including a $2.5 million award in 2024 from its National Center for Advancing Translational Sciences (NCATS) and a $2.3 million SBIR Fast-Track award from the National Institute of General Medical Sciences in 2023.

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.
