Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

University of Houston receives funding to support diverse cardiovascular researchers

pumping up innovation

University of Houston professors have received a nearly $800,000 grant to create a new summer program that will support diverse future researchers.

The National Heart, Lung, and Blood Institute provided $792,900 in grant funding to Bradley McConnell, professor of pharmacology at the UH College of Pharmacy, and Tho Tran, research assistant professor of chemistry at the UH College of Natural Sciences and Mathematics.

The funding will go toward created a summer program called the University of Houston Cardiovascular Undergraduate Research Experience, or UH-CURE. Ten undergraduate students per year will be selected for five years in cardiovascular research across disciplinary lines.

"We are so grateful to be able to provide talented students across the U.S. an opportunity to experience our excellent cardiovascular research environment,” Tran says in a news release. “We want UH-CURE participants to gain confidence in their research abilities through our hands-on approach and the skillset to navigate future challenges through our professional training.”

The goal is to increase students’ interest in cardiovascular research, and students have the opportunity to receive a $6,000 stipend, travel to a globally recognized cardiovascular research conference, and take part in on-campus housing and a food allowance. The summer program will also try to develop research skills, increase awareness of transdisciplinary research, promote diversity and collaborations, cultivate transferable skills necessary for succeeding in graduate school and help facilitate undergraduate students to pursue further training in cardiovascular research.

The program will integrate students into a research lab where they will learn research skills, data analysis, and research integrity. The program will be under the mentorship of a faculty member from across UH’s colleges, and include workshop and enrichment activities.

McConnell and Tran previously formed the American Heart Association-funded UH-HEART pilot program, which focused on cardiovascular research. They expanded on that initiative with UH-CURE, which includes cardiovascular research across disciplinary lines from community engagement and population-based research to basic, translational, and applied research. UH-CURE also helps prepare for careers in cardiovascular research.

“We all know that a diverse environment leads to a much better generation of ideas and solutions,” Tran adds. “We hope to bring that strength to the future of cardiovascular research through our students.”

Innovative Houston urban farm scores national award for green work

to the moon

A Houston urban farm has earned national recognition for its innovative approach to water conservation. Moonflower Farms won the American Heart Association's Foodscape Innovation Excellence Award, which recognizes positive changes in the foodscape, a term for all of the places where food is produced, purchased, or consumed.

The Heart Association selected Moonflower's submission, titled "Sustainable Farming Through Water Conservation," from 26 entries. Dallas' Restorative Farms earns the Foodscape Innovation Consumer Choice Award.

"These two innovations demonstrate a way of producing food that promotes affordability and equitable access, and the American Heart Association is proud to recognize these efforts," AHA chief medical officer for prevention Eduardo Sanchez said in a release.

Located in a 20,000-square-foot greenhouse south of downtown, Moonflower operates what it describes as Houston's first vertical indoor farm. The method both reduces the amount of space needed to grow the farm's microgreens, lettuces, herbs and edible flowers and it eliminates the disruptions caused by adverse weather conditions, which allows the farm to produce year round.

Moonflower uses a closed-loop system for capturing rainwater to feed its crops. The water is treated and oxygenated so that it can be reused. Not having to pay for water from the City of Houston allows the farm to operate more economically and sell its produce at an affordable price to restaurants and individuals.

"Our hydroponic farm uses 90-percent less water than conventional farms," Moonflower founder and CEO Federico Marques said in a statement. "We provide year-round produce to residents in historically underserved communities and donate produce to local charitable food systems."

One of those charities is Houston non-profit Second Servings, which "rescues" food from restaurants and events and distributes it to food pantries and other resources.

"The donations we receive from Moonflower Farms are incredible," Second Servings founder and president Barbara Bronstein said. "Their hydroponically grown greens are so appreciated by the needy Houstonians we serve, who lack affordable, convenient access to fresh produce."

Recently, Moonflower introduced a SupaGreens subscription box that allows customers to purchase greens weekly, bimonthly, or monthly. The box is delivered directly to consumers.

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.
