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."

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.

Houston digital health platform Koda lands strategic investment

money moves

Houston-based advance care planning platform Koda Health has added another investor to the lineup.

The company secured a strategic investment for an undisclosed amount from UPMC Enterprises, the commercialization arm of the University of Pittsburgh Medical Center. The funding is part of Koda's oversubscribed series A funding round that closed in October, according to a release.

"UPMC Enterprises’ investment is a meaningful signal, not just to Koda, but to the broader market," Dr. Desh Mohan, chief medical officer and co-founder of Koda Health, said in the news release. "It validates that health systems are ready to invest in infrastructure that makes advance care planning work the way it should: proactively, at scale, and with the human support that these conversations require. Having UPMC Enterprises as a strategic investor puts us in a unique position to prove what's possible."

Koda has raised $14 million to date, according to a representative from the company. Its series A round was led by Evidenced, with participation from Mudita Venture Partners, Techstars and the Texas Medical Center last year. At the time, the company said the funding would allow it to scale operations and expand engineering, clinical strategy and customer success. The company described the round as a "pivotal moment," as it had secured investments from influential leaders in the healthcare and venture capital space.

Koda Health, which was born out of the TMC's Biodesign Fellowship in 2020, saw major growth last year, as well, and now supports more than 1 million patients nationwide through partnerships with Cigna Healthcare, Privia Health, Guidehealth, Sentara, UPMC and Memorial Hermann Health System.

The company integrated its end-of-life care planning platform with Dallas-based Guidehealth in April 2025 and with Epic Systems in July 2025. It also won the 2025 Houston Innovation Award in the Health Tech Business category. Read more here.
