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

childhood cancer

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.”

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

5 ways technology is transforming the workplace for people with disabilities

Guest Column

When Camp For All opened its barrier-free gates more than 30 years ago, our founders believed that design could level the playing field for children and adults with challenging illnesses, disabilities, or special needs. Today, that same philosophy is necessary for workplaces across Greater Houston and beyond; only now the ramps and handrails are digital as much as physical, powered by artificial intelligence (AI) and innovation.

Technology has significantly transformed the workplace for individuals with disabilities, making it easier for them to perform their roles with greater efficiency and independence. Tools such as ergonomic workstations, adaptive keyboards, closed captioning, dictation software, screen magnifiers, and robotics help customize the work environment to accommodate various needs. Additionally, advancements in remote work technology have opened the door to broader employment opportunities, reducing physical barriers to participation in the workforce.

Here are five ways that technology turns “reasonable accommodation” into universal enablement and why every employer should take note.

From closed-captioning to real-time conversation

Ten years ago, businesses relied upon human typists and translators to convert conversations and presentations for those with disabilities. Today, AI speech-to-text engines like Microsoft 365’s Live Captions or Google Workspace’s Meet Transcripts render spoken words into on-screen text across 40-plus languages and dialects in milliseconds. This means deaf and hard-of-hearing employees can follow rapid brainstorming sessions without waiting for a post-meeting transcript.

If you are not already using these tools in your workplace, it is easy to start. Most of these services are free or very low-cost, but produce a high return in employee productivity. Individuals with hearing deficiencies can participate in real-time conversations, give feedback, and bring their unique perspectives to the conversation. These tools also enhance productivity for the larger team by providing all employees with a greater flow of ideas, engagement, and recall.

Voice is the new keyboard

Voice assistants like Siri, Alexa, and Windows Voice Access have matured into integrated tools for everyday life and business. They can now handle paragraph-length dictation, code snippets, and complex spreadsheet commands.

Workers with limited dexterity or sight can participate fully in work tasks, which can level the playing field so everyone can succeed and contribute significantly to the workplace. Additionally, voice-assisted technology can help older employees or employees with differing physical needs continue working longer and retain vital organizational knowledge and expertise, contributing to their team's success.

Readability and writing coaches at scale

The new and highly sensitive AI-powered editors, such as GrammarlyGO and Microsoft Editor, flag jargon, suggest plain-language rewrites, and even adjust tone for cognitive accessibility. This can be a game-changer for neurodivergent professionals, including people with dyslexia or ADHD, as they have to use less brain power decoding dense emails and can get help writing responses in their workplace correspondence.

Again, these free or low-cost tools enable all team members to contribute their unique ideas and perspectives when working together to address workplace challenges, better serve clients, and increase productivity.

Alternative text that captures context

Image-recognition models can now draft alt-text beyond “blue shirt on chair.” Tools like Adobe’s Intelligent Captioning or Meta’s Automatic Alt Text describe emotion, action, and even brand context, giving screen-reader users a richer experience.

Employees with blindness or low vision are more likely to navigate online documents, presentations, and requests independently. These technologies also reduce workloads on marketing teams and help them meet accessibility standards without extensive labor and time.

For businesses that want a varied workforce that brings multiple perspectives, these tools give them a power that hasn’t been harnessed before. If employees living with disabilities have more tools at their disposal, they can, in turn, target specific customers in new ways.

Robots and exoskeletons

Many of us remember The Jetsons cartoon show from the 1960s and how far-fetched their housekeeper robot Rosie seemed then. But now, affordable robots and wearable devices to support employees with spinal cord injuries, chronic pain, and disabilities are helping perform repetitive tasks and reducing strain for everyday work tasks.

These devices may revolutionize unemployment to full-time employment opportunities for many individuals. Devices like ABB’s GoFa and Ottobock’s Paexo can help employers reduce injury claims and retain skilled staff; it’s truly a win-win for employees and employers.


The impact is universal

Eight-foot-wide accessible sidewalks, like the ones we have at Camp For All, help wheelchair users, parents pushing a stroller, and travelers rolling luggage. Similarly, AI captions level the playing field for hearing-impaired colleagues, neurodiverse team members, aging professionals, and every employee skimming a meeting on mute. When we treat accessibility as an innovation driver rather than a compliance checklist, we unleash the potential of productivity, loyalty, and creativity throughout our organizations and companies.

Camp For All sees this throughout the year: when design removes barriers, people discover abilities they never knew they had. Let’s bring that spirit into every Houston boardroom and breakroom — because an inclusive workplace isn’t just the right thing, it’s the smart thing.

Pat Prior Sorrells is president and CEO of Camp For All, a Texas-based nonprofit organization. Located in Burton, Texas, the 206-acre Camp For Allsite was designed with no barriers for children and adults with special needs to experience the joy of camping and nature. Camp For All collaborates with more than 65 nonprofit organizations across the Greater Houston area and beyond to enable thousands of campers and their families to discover life each year. She speaks regularly on the need for inclusive design in public spaces.

CPRIT grants $22M to bring top cancer researchers to Houston

fresh funding

Several prominent cancer researchers are coming to the Houston area thanks to $22 million in grants recently awarded by the Cancer Prevention and Research Institute of Texas (CPRIT).

The biggest CPRIT recruitment grant — $6 million — went to genetics researcher Jean Gautier. Gautier, a professor of genetics and development at Columbia University’s Institute for Cancer Genetics, is joining the University of Texas MD Anderson Cancer Center to continue his research.

The website for Gautier’s lab at Columbia provides this explanation of his research:

“The main objective of our research is to better understand the molecular mechanisms responsible for the maintenance of genome stability. These controls are lost in cancer, which is characterized by genomic instability.”

Aside from his work as a professor, Gautier is co-leader of the Herbert Irving Comprehensive Cancer Center’s Cancer Genomics and Epigenomics Program at Columbia.

Other recipients of CPRIT recruitment grants include:

  • $2 million to recruit Xun Sun from the Scripps Research Institute to the University of Texas Medical Branch at Galveston.
  • $2 million to recruit Mingqi Han from the University of California, Los Angeles to MD Anderson.
  • $2 million to recruit Matthew Jones from Stanford University to MD Anderson.
  • $2 million to recruit Linna An from the University of Washington to Rice University.
  • $2 million to recruit Alissa Greenwald from the Weizmann Institute of Science to MD Anderson.
  • $2 million to recruit Niladri Sinha from Johns Hopkins University to the Baylor College of Medicine.
  • $2 million for Luigi Perelli to stay at MD Anderson so he can be put on a tenure track and set up a research lab.
  • $2 million for Benjamin Schrank to stay at MD Anderson so he can be put on a tenure track and set up a research lab.

  • Baylor College of Medicine
  • Houston Methodist Research Institute
  • Rice University
  • Texas Southern University
  • University of Houston
  • University of Texas Health Science Center at Houston
  • University of Texas MD Anderson Cancer Center
  • University of Texas Medical Branch at Galveston

In addition, nearly $4.45 million in cancer prevention grants were awarded to one researcher at the University of Texas Medical Branch at Galveston and another at Texas Southern University.

Also, five Houston businesses benefited from CPRIT grants for product development research:

  • Allterum Therapeutics, $2,999,996
  • CTMC, $1,342,178
  • Instapath, $900,000
  • Prana Surgical, $900,000
  • InformAI, $465,188

“Texas is a national leader in the fight against cancer,” said Kristen Pauling Doyle, CPRIT’s CEO. “We can measure the return on investment from CPRIT grants … not only in the economic benefits flowing from increased financial activity and jobs in the state, but more importantly in the cancers avoided, detected early, and treated successfully. Thanks to the Legislature’s vision, this commitment is saving lives.”

Overall, CPRIT approved 61 grants totaling more than $93 million in this recent round of funding.
