Houston-born and bred medical device company, Procyrion, has completed its series E with a raise of $57.7 million, including the conversion of $10 million of interim financing.

Procyrion is the company behind Aortix, a pump designed to be placed in the descending thoracic aorta of heart failure patients, which has been shown to improve cardiac performance in seriously ill subjects. The money raised will allow the company to proceed with a the DRAIN-HF Study, a pivotal trial that will be used for eventual FDA approval and commercialization.

The Aortix is the brainchild of Houston cardiologist Reynolds Delgado. According to Procyrion’s CSO, Jace Heuring, Delgado, gained some of his experience with devices for the heart working with legendary Texas Heart Institute surgeon O.H. “Bud” Frazier. He filed his first patents related to the Aortix in 2005.

Heuring says that the first prototypes were built in 2011, followed by the final design in 2018. CEO Eric Fain, a California-based MD and with more than 30 years in the medical device industry, joined the company in 2018 ahead of the final design, primed to bring Aortix to the public. He visits the company’s Houston headquarters, across the street from Central Market, on a regular basis.

The device’s pilot study of 18 patients was completed in 2022. Those encouraging results paved the way for the current study, which will include an enrollment of 134 patients. The randomized study will seek to treat patients with acute decompensated heart failure. Half will be treated with standard-of-care therapy, the other half will be catheterized with an Aortix pump. A separate arm of the study will seek to treat end-stage heart failure patients who would otherwise be deemed too sick for either a transplant or an LVAD permanent pump. Fort-five healthcare centers in the United States will participate, including Texas Heart Institute.

“One of the key characteristics is [the patients] are retaining a lot of fluid,” explains Heuring in a video interview. “And when I say a lot, I mean it could be 25 or 30 or 40 pounds of fluid or more. When we put our pump in, one of the main goals is to reduce that fluid load.”

On average, about 11 liters of fluid came off of each patient. Many of those end-stage patients had previously been considered for both a heart and kidney transplant, but after using the Aortix, their kidneys responded so well that they were able to get only the heart transplant.

“These patients really are in dire straits and come into the hospital and today the only proven therapy to help these patients is to administer high doses of intravenous diuretic and some other cardiac drugs and in about 25 percent of patients those therapies are ineffective,” says Fain.

If Aortix gains approval, these sickest of the sick, usually consigned to hospice care, will have hope.

Thanks to the Series E, led by Houston’s Fannin Partners, returning investors, including Bluebird Ventures, the Aortix is inching closer to commercialization. Besides funding the DRAIN-HR study, Procyrion will also use the funds for internal programs to improve product manufacturability. One more step towards meaning advanced heart failure may not always be a death sentence.

Last month, Atul Varadhachary, managing director of Fannin, joined the Houston Innovators Podcast and alluded to Procyrion's raise. The company was born out of Fannin and still resides in the same building as Fannin.

UH lands $1.2M NIH grant to fight superbugs using AI, quantum sensing

drug defense

The fight against antibiotic-resistant bacteria like MRSA is getting science fiction-like upgrades at the University of Houston thanks to a new four-year, $1.26 million grant from the National Institutes of Health.

The university says the recent funding brings total federal support up to $3.5 million for 11 years for the project, which uses AI and quantum-sensing technology to better understand how bacterial proteins develop resistance to drugs.

Any medical professional will tell you that one of the worst things that can happen is almost killing an infection. Bacteria that survive attacks from conventional antibiotic treatments emerge tougher, more resistant and more aggressive than before–making them much harder to treat. A good example is the superbug methicillin-resistant Staphylococcus aureus (MRSA).

UH chemistry professors Yuhong Wang and Shoujun Xu are working on this issue. They know full well that fighting superbugs requires new technology and new approaches, which is what they aim to pioneer with their new grant.

“Drug-resistant bacterial infections such as MRSA are becoming harder to treat, creating an urgent need for faster ways to understand how antibiotics and other small molecules interact with bacterial proteins,” Wang said in a news release.

Wang and Xu’s work centers around GTP, a cellular fuel that can cause tiny changes to a cell's structure when it mutates. Sometimes, those shape changes make it easier for drugs to breach the wall and attack the cells.

The UH scientists are employing AlphaFold, an AI-powered tool that can scan large molecular libraries in seconds. From these models, they can see promising drug combinations for future testing.

Once identified, the team uses their invention, super-resolution force spectroscopy, to monitor the cells. Tiny magnetic beads are attached to genetic material, then magnified to see how strong that material is when pulled. They can measure this incredible microscopic process through an atomic magnetometer, typically used in quantum physics. Combined, all these tools allow a high-definition look at how each molecule might respond to new chemical approaches.

“We're the only chemists in the world that use an atomic magnetometer for biological research,” Xu said. “It's a technique developed by physicists, and there is usually a gap between techniques developed by physicists and biological applications. Yuhong and I have been bridging that gap together for the past 10 years.”

Eventually, Wang and Xu hope to develop powerful software that can be used by drug manufacturers to model cellular responses. With enough predictive data, the software could even get ahead of superbugs’ own mutation, allowing drugs to be developed before new strains arrive.

"We want an algorithm where you input a protein sequence, score the mutation hotspots, and develop new inhibitors before a drug-resistant species even emerges," Wang added.

SpaceX to get more than 700 acres of Texas wildlife refuge in land swap

Space News

A federal judge on Monday, September 21, refused to block the Trump administration from giving SpaceX more than 700 acres of wildlife refuge as part of a land swap in Texas, while environmental groups vowed to continue their legal challenge.

U.S. District Judge Fernando Rodriguez Jr. declined the plaintiffs' request for a preliminary injunction to prevent the parcel exchange, saying they failed to prove it would worsen ecological risks to a Gulf Coast region already transformed by billionaire Elon Musk’s rocket operations.

In June, the U.S. Fish and Wildlife Service approved moving forward with the deal with SpaceX, which would surrender 683 acres the company owns in exchange for the federal land in the Lower Rio Grande Valley National Wildlife Refuge. The 103,000-acre refuge spans four counties along the Texas border and is home to animal habitats and historical landmarks.

Maps show the land SpaceX would acquire would be closer to the company's launchpad near the U.S.-Mexico border.

The swap amounts to a gift of public lands to SpaceX, “clearing the way for bulldozers to tear into this wildlife refuge as soon as next week and turn a public treasure into a private payday,” said Laiken Jordahl, a spokesperson with the Center for Biological Diversity, which filed the lawsuit alongside other opponents including tribal groups. Jordahl said Monday that the litigation will continue even as the exchange goes forward.

“This court order is not the final word. These lands hold incredible spiritual, historical and conservation value for the people and wildlife of South Texas. We won’t stop fighting to keep this irreplaceable public wildlife refuge safe from SpaceX bulldozers,” Jordahl said in a statement.

The lawsuit asks the federal court to halt the exchange, which has worried SpaceX opponents in the area who have long criticized the company's expanding footprint over lost access to beaches and concerns over exploding rockets.

The Fish and Wildlife Service didn’t respond to a request for comment on Monday’s decision. Previously, a spokesperson had said the agency does not comment on ongoing litigation.

The agency issued a final environmental assessment report in June that determined the exchange would cause no significant impact to the area. The report said the federal government believed the acquisition would represent a “net conservation benefit” and provide “substantial long-term conservation value and improving landscape-scale habitat connectivity across refuges in South Texas.”

The judge said that the plaintiffs offered “relatively weak” evidence of environmental harm.

“While they rightfully argue that the preservation of wildlife and historical lands furthers the public interest, they present no evidence demonstrating that the Property will suffer aesthetic, environmental, cultural, or historical degradation during the pendency of this lawsuit,” Rodriguez wrote in his ruling.

In addition, the judge said a preliminary injunction would result in modifications to SpaceX’s development plans, “placing additional hardship on the company’s ability to meet milestones and contractual obligations.”

SpaceX did not return an email seeking comment on the judge's ruling.

The space exploration company first broke ground in Texas more than a decade ago and has expanded rapidly, so much that SpaceX employees last year voted to incorporate their own local government called Starbase.
