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."

Houston researchers: Here's what it takes to spot a great new idea

houston voices

Having a “promotion focus” really does create a mental lens through which new ideas are more visible.

Key findings:

  • New ideas can be crucially important to businesses, driving innovation and preventing stagnation.
  • Recognizing those ideas, though, isn’t always easy.
  • Nurturing what is known as “promotion focus” can help managers spot fresh ideas.

Whenever the late surgeon Michael DeBakey opened a human chest, he drew on a lifetime of resources: the conviction that heart surgery could and should be vastly improved, the skill to venture beyond medicine’s known horizons and the vision to recognize new ideas in everyone around him, no matter how little formal training they had.

Appreciating new ideas is the heartbeat of business as well as medicine. But innovation is surprisingly hard to recognize. In a pioneering 2017 article, Rice Business Professor Jing Zhou and her colleagues published their findings on the first-ever study of the traits and environments that allow leaders to recognize new ideas.

Recent decades have produced a surge of research looking at how and when employees generate fresh ideas. But almost nothing has been written on another crucial part of workplace creativity: a leader’s ability to appreciate new thinking when she sees it.

Novelty, after all, is what drives company differentiation and competitiveness. Work that springs from new concepts sparks more investigation than work based on worn, already established thought. Companies invest millions to recruit and pay star creatives.

Yet not every leader can spot a fresh idea, and not every workplace brings out that kind of discernment. In four separate studies, Zhou and her coauthors examined exactly what it takes to see a glittering new idea wherever it appears. Their work sets the stage for an entirely new field of future research.

First, though, the team had to define their key terms. “Novelty recognition” is the ability to spot a new idea when someone else presents it. “Promotion focus,” previous research has shown, is a comfort level with new experiences that evokes feelings of adventure and excitement. “Prevention focus” is the opposite trait: the tendency to associate new ideas with danger, and respond to them with caution.

But does having “promotion focus” as opposed to “prevention focus” color the ability to see novelty? To find out, Zhou’s team came up with an ingenious test, artificially inducing these two perspectives through a series of exercises. First, they told 92 undergraduate participants that they would be asked to perform a set of unrelated tasks. Then the subjects guided a fictional mouse through two pencil and paper maze exercises.

While one exercise showed a piece of cheese awaiting the mouse at the end of the maze (the promise of a reward), the other maze depicted a menacing owl nearby (motivation to flee).

Once the participants had traced their way through the mazes with pencils, they were asked to rate the novelty of 33 pictures — nine drawings of space aliens and 24 unrelated images. The students who were prepped to feel an adventurous promotion focus by seeking a reward were much better at spotting the new or different details among these images than the students who’d been cued to have a prevention focus by fleeing a threat.

The conclusion: a promotion focus really does create a mental lens through which new ideas are more visible.

Zhou’s team followed this study with three additional studies, including one that surveyed 44 human resource managers from a variety of companies. For this study, independent coders rated the mission statements of each firm, assessing their cultures as “innovative” or “not innovative.” The HR managers then evaluated a set of written practices — three that had been in use for years, and three new ones that relied on recent technology. The managers from the innovative companies were much better at rating the new HR practices for novelty and creativity. To recognize novelty, in other words, both interior and external environments make a difference.

The implications of the research are groundbreaking. The first ever done on this subject, it opens up a completely new research field with profound questions. Can promotion focus be created? How much of this trait is genetic, and how much based on natural temperament, culture, environment and life experience? Should promotion focus be cultivated in education? If so, what would be the impact? After all, there are important uses for prevention focus, such as corporate security and compliance. Meanwhile, how can workplaces be organized to bring out the best in both kinds of focus?

Leaders eager to put Zhou’s findings to use right away, meanwhile, might look to the real-world model of Michael DeBakey. Practice viewing new ideas as adventures, seek workplaces that actively push innovation and, above all, cultivate the view that every coworker, high or low, is a potential source of glittering new ideas.
