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.

UH research team receives grant to fight aggressive pediatric cancer

cancer research

Researchers at the University of Houston have received a $3.2 million grant from the National Institutes of Health to help find innovative ways to treat Rhabdomyosarcoma, or RMS.

According to a statement from the university, RMS is a malignant soft tissue sarcoma that has a higher incidence in young children and is responsible for 8 percent of pediatric cancer cases with a relatively low survival rate.

One way UH is working on the issue is by studying how and why RMS cells, which are found most often in muscle tissue, divide uncontrollably without ever maturing into normal muscle cells. The researchers aim to tackle a target inside RMS cells known as TAK1, which plays a key role in regulating cell growth.

“By targeting TAK1, we aim to stop the cancer at its source and help the cells develop normally,” Ashok Kumar, the Else and Philip Hargrove Endowed Professor of Drug Discovery at the UH College of Pharmacy and director of the Institute of Muscle Biology and Cachexia, said in a news release. “This approach could lead to new and better treatments for RMS.”

According to UH, preliminary results demonstrated that TAK1 is highly activated in embryonal RMS cells, which are found in younger children; alveolar RMS cells, which are found in older children and teens; and human RMS samples. This suggests that the protein plays a major role in the development of this form of cancer.

The team still aims to uncover how the protein helps RMS cancer grow and plans to evaluate how blocking TAK1 can be used as a therapeutic.

“Blocking TAK1, either by changing the genes (genetic approaches) or using drugs (pharmacological approaches), can stop certain harmful behaviors in cancer cells,” Kumar added. “This was tested both in lab-grown cells and in living models, showing that TAK1 is a key target to control RMS cancer’s spread and aggressiveness, and inhibits tumor formation.”

Houston biotech startup raises millions to battle pediatric cancer

fresh funds

Allterum Therapeutics Inc. has built a healthy launchpad for clinical trials of an immunotherapy being developed to fight a rare form of pediatric cancer.

The Houston startup recently collected $1.8 million in seed funding through an investor group associated with Houston-based Fannin Innovation Studio, which focuses on commercializing biotech and medtech discoveries. Allterum has also brought aboard pediatric oncologist Dr. Philip Breitfeld as its chief medical officer. And the startup, a Fannin spinout, has received a $2.9 million grant from the Cancer Prevention Research Institute of Texas.

The funding and Breitfeld's expertise will help Allterum prepare for clinical trials of 4A10, a monoclonal antibody therapy for treatment of cancers that "express" the interleukin-7 receptor (IL7R) gene. These cancers include pediatric acute lymphoblastic leukemia (ALL) and some solid-tumor diseases. The U.S. Food and Drug Administration (FDA) has granted "orphan drug" and "rare pediatric disease" designations to Allterum's monoclonal antibody therapy.

If the phrase "monoclonal antibody therapy" sounds familiar, that's because the FDA has authorized emergency use of this therapy for treatment of COVID-19. In early January, the National Institute of Allergy and Infectious Diseases announced the start of a large-scale clinical trial to evaluate monoclonal antibody therapy for treatment of mild and moderate cases of COVID-19.

Fannin Innovation Studio holds exclusive licensing for Allterum's antibody therapy, developed at the National Cancer Institute. Aside from the cancer institute, Allterum's partners in advancing this technology include the Therapeutic Alliance for Children's Leukemia, Baylor College of Medicine, Texas Children's Hospital, Children's Oncology Group, and Leukemia & Lymphoma Society.

Although many pediatric patients with ALL respond well to standard chemotherapy, some patients continue to grapple with the disease. In particular, patients whose T-cell ALL has returned don't have effective standard therapies available to them. Similarly, patients with one type of B-cell ALL may not benefit from current therapies. Allterum's antibody therapy is designed to effectively treat those patients.

Later this year, Allterum plans to seek FDA approval to proceed with concurrent first- and second-phase clinical trials for its immunotherapy, says Dr. Atul Varadhachary, managing partner of Fannin Innovation Studio, and president and CEO of Allterum. The cash Allterum has on hand now will go toward pretrial work. That will include the manufacturing of the antibody therapy by Japan's Fujifilm Diosynth Biotechnologies, which operates a facility in College Station.

"The process of making a monoclonal antibody ready to give to patients is actually quite expensive," says Varadhachary, adding that Allterum will need to raise more money to carry out the clinical trials.

The global market for monoclonal antibody therapies is projected to exceed $350 billion by 2027, Fortune Business Insight says. The continued growth of these products "is expected to be a major driver of overall biopharmaceutical product sales," according to a review published last year in the Journal of Biomedical Science.

One benefit of these antibody therapies, delivered through IV-delivered infusions, is that they tend to cause fewer side effects than chemotherapy drugs, the American Cancer Society says.

"Monoclonal antibodies are laboratory-produced molecules engineered to serve as substitute antibodies that can restore, enhance or mimic the immune system's attack on cancer cells. They are designed to bind to antigens that are generally more numerous on the surface of cancer cells than healthy cells," the Mayo Clinic says.

Varadhachary says that unlike chemotherapy, monoclonal antibody therapy takes aim at specific targets. Therefore, monoclonal antibody therapy typically doesn't broadly harm healthy cells the way chemotherapy does.

Allterum's clinical trials initially will involve children with ALL, he says, but eventually will pivot to children and adults with other kinds of cancer. Varadhachary believes the initial trials may be the first cancer therapy trials to ever start with children.

"Our collaborators are excited about that because, more often than not, the cancer drugs for children are ones that were first developed for adults and then you extend them to children," he says. "We're quite pleased to be able to do something that's going to be important to children."

New TMC partnership aims to grow Houston’s biomanufacturing workforce

workforce partnership

Houston is a frontrunner in the race to introduce and manufacture advanced therapeutics to the medical world. A new agreement between the Texas Medical Center (TMC) and San Jacinto College (SJC) aims to speed more experts and their technologies towards the finish line.

Earlier this month, the world's largest medical center and the nation’s second-ranked community college announced their new partnership that will set students on a path towards careers not only in life sciences in general, but also in pharmaceutical and biomanufacturing specifically.

SJC already has programs in those majors—its first graduates are now joining the workforce—but working with TMC will help the college recruit new students, as well as aid in enrollment and participation. Thanks to this collaboration, SJC students will benefit from more experiential learning and be able to transition more smoothly into the next steps in their training.

“Houston is a premier global hub for life sciences and biotechnology, and the talent we need to advance therapeutic drugs, diagnostics, and cell and gene therapy is already here,” William McKeon, the TMC’s president and CEO, said in a news release. “With more companies choosing to establish their headquarters in Houston and the daily breakthroughs happening across the TMC campus, partnering with San Jacinto College is an important step toward sustaining that momentum and unlocking even greater innovation and growth through the promising talent that already exists within our state.”

The partnership is currently slated to last two years, but the institutions have the option to extend after that.

For students, their journey to becoming scientists will likely start with Biopath @ TMC, a program that introduces high school students to biomanufacturing careers and what it takes to pursue one. Since its inception two years ago, the program has worked with more than 2,000 students around Harris County.

“This partnership exemplifies San Jacinto College’s ability to design and deliver programs that align with current workforce demands while opening doors for untapped talent across the Houston region,” Brenda Hellyer, SJC chancellor, said in the release. “TMC is a key industry leader in our region, and San Jacinto College has a unique global curriculum that provides the foundation and skills required for students to succeed and graduates to thrive in meaningful careers that will contribute to the innovation and advancement of the life sciences.”

Thanks to this new collaboration, more of Houston’s biomanufacturing workforce will soon be locally grown.

Houston legacy planning platform secures $2.5M investment, adds to board

fresh funding

Houston-based Paige, a comprehensive life planning and succession software company, has secured a $2.5 million investment to expand the AI-driven tools on its platform.

The funding comes from Alabama-based 22nd State Banking Company, according to a news release. Paige says it will use the funding to expand automation, AI-driven onboarding and self-service tools, as well as add to its sales and customer success teams.

The company was originally founded by CEO Emily Cisek in 2020 as The Postage and rebranded to Paige last year. It helps users navigate and organize end-of-life planning with features like document storage and organization, password management, and funeral and last wishes planning.

“Too many families are left trying to piece together important information during some of the hardest moments of their lives,” Cisek said in the news release. “This investment allows us to accelerate the next phase of growth for Paige by improving the product and expanding support for our members, our financial institution partners and the communities they serve,”

In addition to the funding news, the company also announced that 22nd State Banking CEO and President Steve Smith will join Paige's board of directors.

“We believe banking should be grounded in relationships and built around the real needs of the people and communities we serve. Paige brings something deeply relevant to that mission," Smith added in the release. "It helps families prepare for the future in a practical and meaningful way, and it gives the banking community new pathways to support customers through important life transitions.”

Paige estimates that $124 trillion in assets will change hands through 2048. Yet about 56 percent of Americans do not have an estate plan.
