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.

UH, Baylor researchers make breakthrough with new pediatric leukemia treatment device

A team of Houston researchers has developed a new microfluidic device aimed at making treatments safer for children with hyperleukocytosis, a life-threatening hematologic emergency often seen in patients with leukemia.

Dr. Fong Lam, an associate professor of pediatrics at Baylor College of Medicine and a pediatric intensive care physician at Texas Children’s Hospital, partnered with Sergey Shevkoplyas, a professor of biomedical engineering at UH, on the device that uses a large number of tiny channels to quickly separate blood cells by size in a process called controlled incremental filtration, according to a news release from UH.

They tested whether performing cell separation with a high-throughput microfluidic device could alleviate the limitations of traditional conventional blood-filtering machines, which pose risks for pediatric patients due to their large extracorporeal volume (ECV), high flow rates and tendency to cause significant platelet loss in the patient. The results of their study, led by Mubasher Iqbal, a Ph.D. candidate in biomedical engineering at UH, were published recently in the journal Nature Communications.

“Continuously and efficiently separating leukocytes from recirculating undiluted whole blood — without device clogging and cell activation or damage — has long been a major challenge in microfluidic cell separation,” Shevkoplyas said in a news release. “Our study is the first to solve this problem.”

Hyperleukocytosis is a condition that develops when the body has an extremely high number of white blood cells, which in many cases is due to leukemia. According to the release, up to 20 percent to 30 percent of patients with acute leukemia develop hyperleukocytosis, and this places them at risk for potentially fatal complications.

The new device utilizes tiny channels—each about the width of a human hair—to efficiently separate blood cells through controlled incremental filtration. According to Lam, the team was excited that the new device could operate at clinically relevant flow rates.

The device successfully removed approximately 85 percent of large leukocytes and 90 percent of leukemic blasts from undiluted human whole blood without causing platelet loss or other adverse effects. It also operates with an ECV that’s about 1/70th of conventional leukapheresis machines, which makes it particularly suitable for infants and small children.

“Overall, our study suggests that microfluidics leukapheresis is safe and effective at selectively removing leukocytes from circulation, with separation performance sufficiently high to ultimately enable safe leukapheresis in children,” Shevkoplyas said in the release.

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 and MD Anderson researchers discover exciting new leukemia treatment

big win

Rice University and MD Anderson researchers have just discovered a potential one-two punch that could, they hope, knock out an insidious disease.

A recent study in the journal Leukemia centers on potential new drugs that, with the help of other medications, can thwart leukemia cells.

Specifically, Rice biochemist Natasha Kirienko and MD Anderson physician-scientist Marina Konopleva screened some 45,000 small-molecule compounds to find a few that targeted mitochondria, according to Rice press materials.

In this innovative new study, the team selected eight of the most promising compounds, identified between five and 30 closely related analogs for each, and conducted tens of thousands of tests to systematically determine how toxic each analog was to leukemia cells. This was measured both when administered individually or in combination with existing chemotherapy drugs like doxorubicin, notes a release.

Previously, Kirienko’s lab had shown the eight compounds targeted energy-producing machinery inside cells called mitochondria. Mitochondria, which work nonstop in every living cell, wear out with use. The chosen eight compounds induce mitophagy, which can be described as how cells decommission and recycle deficient and used-up.

Notably, during times of extreme stress, cells can temporarily forgo mitophagy for an emergency energy boost. Previous research has shown leukemia cells have far more damaged mitochondria than healthy cells and are also more sensitive to mitochondrial damage than healthy cells.

Thus, Kirienko and Konopleva reasoned that mitophagy-inducing drugs might weaken leukemia cells and make them more susceptible to chemotherapy. Synergy — using two or more drugs in treatment — is key.

“The point of synergy is that there are concentrations, or dosages, where a single drug doesn't kill,” Kirienko said. “There is no death of healthy cells or cancer cells. But administering those same concentrations in combination can kill a considerable amount of cancer cells and still not affect healthy cells.”

The team tested the toxicity of its mitophagy-inducing compounds and combinations against acute myeloid leukemia (AML) cells, the most commonly diagnosed form of the disease. They then tested the six most effective AML-killing compounds against other forms of leukemia, finding that five were also effective at killing acute lymphoblastic leukemia (ALL) cells and chronic myelogenous leukemia (CML) cells.

Studies found all the mitophagy-inducing drugs caused far less harm to healthy cells.

Finally, the researchers tested one of the most effective mitochondria-targeting compounds, PS127E, using a cutting-edge technique called a patient-derived xenograft (PDX) model. Also referred to as a “mouse clinical trial,” mice are implanted with cancer cells from a leukemia patient. As the cells grow, the mouse is exposed to a drug or combination of drugs as a closer-than-cells test of the treatment’s effect.

Importantly, PDX tests on one compound, PS127E, showed it was effective at killing AML cells in mice, Rice notes, signaling promising news.

“Although this is very promising, we’re still some distance from having a new treatment we can use in the clinic,” Kirienko added. “We still have a lot to discover. For example, we need to better understand how the drugs work in cells. We need to refine the dose we think would be best, and perhaps most importantly, we need to test on a wide variety of AML cancers. AML has a lot of variations, and we need to know which patients are most likely to benefit from this treatment and which are not. Only after we’ve done that work, which may take a few years, would we be able to start testing in humans.”

CPRIT CEO: Houston’s $2B in funding is transforming cancer research and prevention

fighting cancer

With its plethora of prestigious health care organizations like the University of Texas MD Anderson Cancer Center, UTHealth Houston, and the Baylor College of Medicine, Houston sits at the heart of cancer research and prevention in Texas.

Of course, it takes piles of cash to support Houston’s status as the state’s hub for cancer research and prevention. Much of that money comes from the Cancer Prevention and Research Institute of Texas (CPRIT).

Data supplied by CPRIT shows organizations in Harris County gained $2.3 billion in institute funding from 2009 through 2025, or nearly $145 million per year. That represents almost 60 percent of the roughly $4 billion that CPRIT has granted to Texas institutions over a 16-year period.

“The life sciences ecosystem that has developed and changed in Houston is phenomenal,” Kristen Doyle, who became the agency’s CEO in July 2024, tells InnovationMap. “In the next decade, we will look back and see a great transformation.”

That ecosystem includes more than 1,100 life sciences and biotech companies, according to the Greater Houston Partnership.

Houston plays critical role in clinical trials

Texas voters approved the creation of CPRIT in 2007. Twelve years later, voters agreed to earmark an extra $3 billion for CPRIT, bringing the state agency’s total investment in cancer research and prevention to $6 billion.

To date, CPRIT money has gone toward recruiting 344 cancer researchers to Texas (mainly to Houston) and has supported cancer prevention services for millions of Texans in the state’s 254 counties. CPRIT funding has also helped establish, expand, or relocate 25 cancer-focused companies. In Houston, MD Anderson ranks as the No. 1 recipient of CPRIT funding.

Regarding cancer research, Doyle says Houston plays a critical role in clinical trials.

“[Clinical trials are] something that CPRIT has focused on more and more. Brilliant discoveries are crucial to this whole equation of solving the cancer problem,” Doyle says. “But if those brilliant ideas stay in the labs, then we’ve all failed.”

Researchers conduct more clinical trials in Houston than anywhere else in the U.S., the Greater Houston Partnership says.

Doyle, a 20-year survivor of leukemia, notes that a minority of eligible patients participate in clinical trials for cancer treatments, “and that’s one of the reasons that it takes so long to get a promising drug to market.”

An estimated 7 percent of cancer patients sign up for clinical trials, according to a study published in 2024 in the Journal of Clinical Oncology.

MD Anderson takes on cancer prevention

Doyle also notes that Houston is leading the charge in cancer prevention.

“We get some national recognition for programs that have been developed in Houston that then can be replicated in other parts of the country,” she says.

Much of the work in Houston focusing on cancer prevention takes place at MD Anderson. The hospital reports that it has received more than $725 million from the CPRIT since 2007, representing approximately 18 percent of CPRIT’s total awards.

“These efforts can have profound impact on the lives of patients and their families, and this funding ensures our exemplary clinicians and scientists can continue working together to drive breakthroughs that advance our mission to end cancer,” Dr. Giulio Draetta, chief scientific officer at MD Anderson, said in a November news release, following the most recent CPRIT award for the hospital totaling more than $29 million.

CPRIT funding for Houston institutions supplements the more than $4.5 billion in federal funding for health and life sciences research and innovations that the Houston area received from 2020 to 2024, according to the Greater Houston Partnership.

“We are curing cancer every single day,” Doyle says of CPRIT. “Every step that we are taking — whether that’s funding great ideas or funding the clinical trials that are bringing promising drugs to Texas and to the world — we are making a difference.”

Houston energy tech co. breaks ground on low-cost hydrogen pilot plant

Coming Soon

Houston’s Lummus Technology and Advanced Ionics have broken ground on their hydrogen pilot plant at Lummus’ R&D facility in Pasadena, Texas.
