Fannin Partners has done it again. The Houston-based life science development group behind medtech companies Procyrion and Allterum Therapeutics announced yesterday that it has launched Radiomer Therapeutics. With an undisclosed amount of pre-seed funding, Radiomer joins the $242 million-strong Fannin portfolio.

Radiomer uses Fannin’s proprietary Raptamer platform to target vectors and ligands for theranostic application. The cancer-fighting technology is a targeting agent that can address serious maladies including breast, lung, colorectal, prostate, and head and neck cancers.

And with Radiomer’s launch, Fannin is moving with its trademark aggressiveness. Lead programs expected to complete Phase 0 imaging/dosimetry trial(s) in cancer patients in the first quarter of next year. Those will be closely followed by therapeutic programs.

“Raptamers combine antibody level affinities with desirable physical and pharmacokinetic properties, and a rapid path to clinic,” Dr. Atul Varadhachary, CEO of Radiomer Therapeutics and Fannin managing partner, says in a press release. “We are deploying this unique platform to develop novel therapies against attractive first-in-class oncology targets.”

Varadhachary has operated Radiomer in stealth mode since its 2023 inception. However, Raptamer has been in the company’s portfolio since 2019. The new company has been using the platform to generate data with the rights to radiopharmaceutical applications for the past year.

“Our lead programs include Radiomers targeting both well-established and first-in-class cancer targets,” adds Dr. Phil Breitfeld, Radiomer’s chief medical officer. “Our imaging/dosimetry trials are designed to provide clinical evidence of tumor targeting and biodistribution information, positioning us to rapidly initiate a therapeutic program(s) if successful.”

For over a decade, Fannin has developed and supported promising life science innovations by garnering grant funding and using its team of expert product developers to build out the technology or treatment. The life science innovation timeline is very different from a software startup's, which can get to an early prototype in less than a year.

"In biotech, to get to that minimally viable product, it can take a decade and tens of millions of dollars," Varadhachary said on the Houston Innovators Podcast earlier this year.

Houston medical device company secures $57.7M to fund journey to FDA approval, commercialization

fresh funding

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.

Houston innovator plays the long game of life science innovation with optimized capital efficiency

HOUSTON INNOVATORS PODCAST EPISODE 222

Commercializing a life science innovation that has the potential to enhance or even save the lives of millions of patients is a marathon, not a sprint. That's how Atul Varadhachary thinks of it, and he's leading an organization that's actively running that race for several different early-stage innovations.

For over a decade, Fannin has worked diligently to develop promising life science innovations — that start as just an idea or research subject — by garnering grant funding and using its team of expert product developers to build out the technology or treatment. The model is different from what you'd see at an accelerator or incubator, and it also varies from the path taken by an academic or research institution.

The life science innovation timeline is very different from a software startup's, which can get to an early prototype in less than a year.

"In biotech, to get to that minimally viable product, it can take a decade and tens of millions of dollars," Varadhachary, managing director at Fannin, says on the Houston Innovators Podcast.



Fannin addresses what Varadhachary calls a twin bottleneck in Houston's life science innovation ecosystem. Not only does Houston not attract the funding biotech startups need desperately to grow their companies, but hiring is a major issue as the city isn't home to an established labor pool of experienced product developers within the industry.

"The challenge is that product development is more complex — it requires innovation, but that's not sufficient. When you ask people why we lag in the product development in the life sciences — although we are home to the largest medical center in the country, we don't even make list of top 10 biotech clusters — the usual answer is that we don't have enough biotech investors," Varadhachary says.

"But that puts the cart before the horse," he continues. "Investors invest in people not just ideas. Although we have an amazing pool of researchers and clinicians, we lack experienced product developers."

In more ways than one, Fannin is addressing this problem. For all of its several ongoing programs, Fannin acts as the leadership team for the technologies. Its core employees — there are about 20 currently — work on all of the companies, which are developing a range life science innovations, from Brevitest, a point-of-use immunoassay platform, to Procyrion, an intra-aortic pump for congestive heart failure patients.

Fannin's programs also range in stage, which Varadhachary outlines on the show to be three different phases. The earliest stage programs will have Fannin's team working directly on early testing, product development, and grant writing, while the later stage programs will have built out a dedicated team and raise venture investment.

Another way Fannin is addressing Houston's lack of life science product developers is through its Fannin Talent Development Program, which has given around 350 individuals an opportunity to gain critical product development experience.

With 10 years under its belt, Fannin — as well as the greater Houston life science innovation ecosystem — is at a point where it can soon produce exits needed to firm up Houston as a life science leader.

"Clearly, we've got the base elements required to be a successful ecosystem, and they continue to grow," Varadhachary says of Houston. "Typically you need one or two really big success stories — especially if those success stories result in a company being sold, leaving behind experienced product developers with money in their pockets — that's often what will supercharge the next cycle of development. I'm hoping that will happen in Houston in the next five years, decade, or so."

Houston medical device company closes $30 million round

Follow the money

A clinical-stage medical device company based in Houston has rounded up $30 million for its Series D funding. Procyrion Inc.'s round was lead by Bluebird Ventures — a new funding partner for the company.

Procyrion is developing a blood pump, called the Aortix™ system, that's optimized for patients with heart and kidney failure. Joining in on the round with Bluebird are return investors, including Fannin Partners, Scientific Health Development, the State of Texas, and an undisclosed strategic investor. This round has now more than doubled the company's total funding, bringing that figure now to $59 million.

"Of the more than 1 million patients per year in the U.S. admitted to the hospital with acute decompensated heart failure, 25 to 30 percent also have worsening renal function," says Eric S. Fain, president and CEO of the company, in a release. "These are typically the most difficult to treat patients with high mortality and rehospitalization rates."

The funds, Fain says, will go toward advancing the medical device, specifically enhancing the system's ability to decongest cardio renal patients in the company's pilot program.

"Today there is a major gap in effective therapies that are available to treat these critically ill patients, and as such, there is a significant opportunity to improve patient outcomes," Fain continues in the release. "The Aortix device is uniquely designed and positioned in the body to simultaneously decrease the workload of the heart and improve kidney function."

The Aortix device is a solution for patients who haven't seen success from medical therapy, but don't have the immediate need for a transplant or more drastic solution. The device is thinner than a pencil, the release says, and can be inserted in a matter of minutes in a cath-lab setting. The size and ease of application could be transformational for the large population of heart patients that would need it.

In addition to the funds, Jeff Bird, managing director of Bluebird Ventures, will join the company's board of directors.

"The Procyrion Aortix device provides an elegant solution for managing heart failure, a serious and difficult-to-treat problem," says Bird in the release. "We are excited to work with this experienced team as they begin clinical testing."

Baylor College of Medicine launches VC fund to invest in biotech startups

fresh funding

Houston’s Baylor College of Medicine just unveiled a new venture capital fund that backs early-stage biotech startups—and it’s already made its first investment.

BCM Legacy Fund I, funded by philanthropies, invested an undisclosed amount in Houston biotech startup Nemea Therapeutics. Nemea, a spinout of the Baylor College of Medicine and Germany’s Lead Discovery Center, is developing an oral drug to treat metastatic triple-negative breast cancer that no longer responds to currently available therapies.

This type of aggressive cancer spreads from the breast to other areas of the body, such as the bones, liver, lungs or brain. Roughly 38,000 to 57,000 Americans are diagnosed each year with metastatic triple-negative breast cancer. One study showed about half of patients survive past the one-year mark following diagnosis and about one-third survive two years.

“Baylor College of Medicine’s laboratories produce discoveries with the potential to change patients’ lives, and too many of them stall where academic funding ends and private investment has not yet begun,” Dr. Jakub Tolar, president, CEO and executive dean of the Baylor College of Medicine, said in a press release. “The BCM Legacy Fund fills that gap, giving our scientists a path to advance their discoveries to patients.”

The National Institutes of Health awards more than $36 billion per year for biomedical research in the U.S., Baylor said. But some biomedical discoveries “never leave the starting line because they don’t yet fit the economics of venture capital,” the college said.

“The forefront of a new model”

The BCM Legacy Fund aggregates philanthropic capital from private foundations and donor-advised funds. It then invests in startups so they can move beyond that starting line and into later-stage investment rounds. The Greater Houston Community Foundation is the fund’s philanthropic partner.

“It’s exciting to be on the forefront of a new model for philanthropic capital,” said Houston entrepreneur and investor Burton Hanson, managing partner of the fund.

“Not only do we hope to solve a real problem by advancing these therapies to the patients who need them most, but we also hope this model will inspire others in the city and beyond toward philanthropic creativity and a posture of ‘I sacrifice; we win.’”

The fund expects to invest in about 15 early-stage startups over a five-year span. Baylor declined to divulge the amount of money in the fund and the size of the investment in Nemea.

Nemea’s “world-class chemistry”

Hanson oversees the Baylor fund alongside Chicago investor Steve Lehmann, who led the University of Chicago’s Innovation Fund.

Lehmann said Nemea, the fund’s first portfolio company, “has world-class chemistry, Baylor biology, and patients with no good options. Our job is to fund the experiments that carry it to the next handoff, so that industry and later-stage investors can take it from there.”

Based at Houston’s massive Texas Medical Center, Nemea plans to start clinical trials next year in collaboration with Baylor’s Lester and Sue Smith Breast Center.

Nemea previously received $9 million from the Lead Discovery Center and a $1.6 million grant from Baylor. Last year, the startup said it was seeking $25 million to $30 million in seed and Series A funding.

Debra McCoy of Houston, a former managing director at BlackRock and former partner at Bain & Co., and Paul Thomas, co-founder and CEO of Spring-based benefits manager Luscinia Health, sit on the Baylor fund’s governing board. Dr. Paul Klotman, former president, CEO and executive dean of Baylor, is a senior strategic adviser.

How does the fund find investment targets?

The Baylor Legacy Fund relies on two tools to help unearth early-stage biotech startups:

  • High-resolution “innovation maps” of research institutions. These maps surface hidden clusters of innovation, identify rising-star researchers and tie pockets of “innovation supply” at Baylor to areas of “innovation demand” in biotech.
  • AI-enhanced due diligence. AI agents assist with due diligence of early-stage biotech startups. The fund says the platform “distills the frameworks we’ve developed over a decade of teaching and investing into a flexible … diligence environment.”

MD Anderson unveils $3.4B expansion with two new Houston cancer care facilities

major expansion

The cutting edge of cancer-fighting technology and science is getting even sharper after MD Anderson announced last week that it will open two new facilities in the Texas Medical Center within the next five years. Inspiration Tower and Prism will expand MD Anderson’s annual patient load in the TMC to 250,000 annually and will incorporate a variety of new techniques.

The $3.4 billion project will add 2 million square feet to MD Anderson's TMC footprint, bringing its total campus size to 22 million square feet by 2032. Located at the corner of Fannin Street and Holcombe Boulevard, the cancer center says the two new facilities will serve as its new "front door" to the TMC.

“Every detail of these buildings, from the technology to the treatment rooms, was designed around our patients who will receive their care in them and our employees who will work in them. The facilities will serve as a physical representation of hope for the patients and their families who will walk through the doors,” Dr. Jeffrey E. Lee, president ad interim of UT MD Anderson, said in a news release. “Inspiration Tower and Prism are the future of cancer care, and we are grateful for the longstanding support and guidance we’ve received from the UT System Board of Regents to bring these projects to life. These facilities are part of the most impactful capital expansion in UT MD Anderson’s history.”

Prism is especially exciting as it will represent fully half of the linear accelerator treatment in the TMC. Linear accelerator is a radiation treatment that uses magnetically charged fields to deliver targeted external radiation therapy, like shooting cancer with a rail gun. The treatment is safer and has fewer side effects than older radiation treatments.

In addition, Prism will contain 12 MRI machines, four CT scanners, two PET-CT units, 18 radiation vaults and seven radiation simulators. Patient comfort has also been put at a premium with multiple gardens and roof overlooks.

“Every patient we treat deserves an environment that reflects the excellence of the care they receive at UT MD Anderson,” Chris McKee, executive vice president and chief strategy officer at UT MD Anderson, added in the release. “Our new facilities will be innovative, agile, adaptable and beautiful, and they will allow us to care for more patients, more effectively – in an environment that enhances healing and well-being. We are building for our future and for every patient who will be counting on us.”

Prism is slated to open in 2030.

Inspiration Tower will have 25 floors of surgical, diagnostic, and treatment services. At 1.4 million square feet, it’s currently expected to be the largest cancer-specific treatment facility in the United States. The tower will be divided into units for specific types of cancer, making it easy to integrate the advancing research being done all over Houston.

Like Prism, Inspiration Tower is specifically designed to offer comfort and reassurance, with more garden space, terraces, and beautiful scenery to ease patient distress. It is expected to open in 2032.

Tesla will pull the plug on Cybertruck production at Texas factory in 2027

Tesla Talk

Tesla’s Cybertruck, the hulking, stainless-steel pickup that inspired devotion and derision with its science-fiction looks, will cease production next year.

CEO Elon Musk announced the model’s demise Friday, November 6, with a curt post on X, his social media site, simply noting production of the vehicle “will be winding down” around the middle of 2027 at its facility outside Austin, Texas. Musk said the move was to allow increased production of its Cybercab robotaxi.

For the Cybertruck, a pet project of Musk who insisted it was Tesla’s best product, it marks an unceremonious end to one of the auto industry’s most ballyhooed debuts.

“Few vehicles in history have generated as much attention,” said Armen Hareyan, whose Torque News site covers autos. “The Cybertruck became a cultural symbol – loved, mocked and impossible to ignore.”

The Cybertruck rolled onto the scene in a dramatic unveiling in 2019, when a Tesla designer hurled a metal ball at the vehicle to demonstrate its supposedly unbreakable glass, only to see it shatter. He repeated the stunt on another window of the truck only to shatter that one, too.

Even as some critics scoffed, Musk was steadfast.

“I just wanted to make a futuristic battle tank — something that looks like it could come out of ‘Blade Runner’ or ‘Aliens’ or something like that but was also highly functional,” he told Automotive News. He called it “a better sports car than a Porsche 911” and “a better truck than an F-150.”

It struck some as the perfect vehicular reflection of the brash, convention-busting Musk.

“A really controversial vehicle unveiled by a controversial individual into a market where none of the electric trucks have been able to really capture demand,” said Spencer Penn, a former Tesla executive who left the company before the Cybertruck’s launch and now heads software developer LightSource.

Penn remembered watching the unveiling and feeling initially revolted by the sight of the Cybertruck, calling its appearance “madness.” But the more he looked at it, the more his opinion changed. He signed up for a pre-sale reservation, though ended up not getting a Cybertruck when Musk’s promises of a price tag under $40,000 went unmet and the first trucks sold for double or more. Penn called the Cybertruck part of Tesla’s adventurous spirit that drives innovation.

“Some of these bets work and some of these bets don’t,” he said.

While the decision to end Cybertruck production may be driven by sales realities, it's also a reflection of Tesla’s shift to autonomous vehicles, on which Musk is betting the company’s future.

Musk once forecast he’d make 250,000 Cybertrucks a year. Kelley Blue Book estimated Tesla sold just 20,237 of the vehicles last year, down about half from the year prior. Sales through the end of September this year were down another 28%, according to Kelley Blue Book.

If the imposing, sharp-angled, dystopian appearance of the Cybertruck weren’t enough to turn many potential buyers away, Musk did so himself by allying with a panoply of right-wing figures, most notably U.S. President Donald Trump. He alienated some customers as his image morphed from eccentric innovator to polarizing force trading his billions for political influence.

Once-passionate Tesla drivers rushed to sell off their cars, or slapped stickers on the bumper declaring, “I bought this before Elon went crazy.” Organizers staged demonstrations outside Tesla showrooms and urged investors to dump shares of the company’s stock. Anger spilled into violence, with Molotov cocktails hurled at Tesla vehicles, charging stations set ablaze, and dealerships covered in graffiti.

Lovers of the Cybertruck became targets, too, subjected to shouts of “Nazi!” and extended middle fingers.

Ross Blankenship is one of them. When he first laid eyes on the Cybertruck, he felt transported to a world from his childhood, when he would play “Halo,” the sci-fi video game. He had to have it.

“I had that sort of child in me wanting to be part of something cool that would change the future of automotive,” Blankenship said in a call from his Cybertruck as he drove through Sunnyside, Colorado. Even as Blankenship found he agreed with Musk on politics, he hated seeing a vehicle he loved turned into a political symbol. “I never bought it for any other reason than the fascination with the future technology of trucks … so that was a little heartbreaking.”

He would buy another Cybertruck again in a heartbeat, calling its end “a sad moment.”
