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.

3 Houston innovators to know this week

who's who

Editor's note: Welcome to another Monday edition of Innovators to Know. Today I'm introducing you to three Houstonians to read up about — three individuals behind recent innovation and startup news stories in Houston as reported by InnovationMap. Learn more about them and their recent news below by clicking on each article.

Aziz Gilani's career in tech dates back to when he'd ride his bike from Clear Lake High School to a local tech organization that was digitizing manuals from mission control. After years working on every side of the equation of software technology, he's in the driver's seat at a local venture capital firm deploying funding into innovative software businesses.

As managing director at Mercury, the firm he's been at since 2008, Gilani looks for promising startups within the software-as-a-service space — everything from cloud computing and data science and beyond.

"Once a year at Mercury, we sit down with our partners and talk about the next investment cycle and the focuses we have for what makes companies stand out," Gilani says on the Houston Innovators Podcast. "The current software investment cycle is very focused on companies that have truly achieved product-market fit and are showing large customer adoption." Read more.

The United States Department of Defense has awarded a grant that will allow the Texas Heart Institute and Rice University to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation and are a long-term option in end-stage heart failure.

The grant is part of the DOD’s Congressionally Directed Medical Research Programs (CDMRP). It was awarded to Georgia Institute of Technology, one of four collaborators on the project that will be designed and evaluated by the co-investigator Yaxin Wang. Wang is part of O.H. “Bud” Frazier’s team at Texas Heart Institute, where she is director of Innovative Device & Engineering Applications Lab. The other institution working on the new LVAD is North Carolina State University.

The project is funded by a four-year, $7.8 million grant. THI will use about $2.94 million of that to fund its part of the research. As Wang explained to us last year, an LVAD is a minimally invasive device that mechanically pumps a person’s own heart. Frazier claims to have performed more than 900 LVAD implantations, but the devices are far from perfect. Read more.

Allterum Therapeutics, a Houston biopharmaceutical company, has been awarded a $12 million product development grant from the Cancer Prevention and Research Institute of Texas (CPRIT).

The funds will support the clinical evaluation of a therapeutic antibody that targets acute lymphoblastic leukemia (ALL), one of the most common childhood cancers.

However, CEO and President Atul Varadhachary, who's also the managing director of Fannin Innovation, tells InnovationMap, “Our mission has grown much beyond ALL.” Read more.

Houston startup scores $12M grant to support clinical evaluation of cancer-fighting drug

fresh funding

Allterum Therapeutics, a Houston biopharmaceutical company, has been awarded a $12 million product development grant from the Cancer Prevention and Research Institute of Texas (CPRIT).

The funds will support the clinical evaluation of a therapeutic antibody that targets acute lymphoblastic leukemia (ALL), one of the most common childhood cancers.

However, CEO and President Atul Varadhachary, who's also the managing director of Fannin Innovation, tells InnovationMap, “Our mission has grown much beyond ALL.”

The antibody, called 4A10, was invented by Scott Durum PhD and his team at the National Cancer Institute (NCI). Licensed exclusively by Allterum, a company launched by Fannin, 4A10 is a novel immunotherapy that utilizes a patient’s own immune system to locate and kill cancer cells.

Varadhachary explained that while about 80 percent of patients afflicted with ALL have the B-cell version, the other 20 percent suffer from T-cell ALL.

“Because the TLL population is so small, there are really no approved, effective drugs for it. The last drug that was approved was 18 or 19 years ago,” the CEO-scientist said. 4A10 addresses this unmet need, but also goes beyond it.

Because 4A10 targets CD127, also known as the interleukin-7 receptor, it could be useful in the treatment of myriad cancers. In fact, the receptor is expressed not just in hematological cancers like ALL, but also solid tumors like breast, lung, and colorectal cancers. There’s also “robust data,” according to Varadhachary for the antibody’s success against B-cell ALL, as well as many other cancers.

“Now what we're doing in parallel with doing the development for ALL is that we're continuing to do additional preclinical work in these other indications, and then at some point, we will raise a series A financing that will allow us to expand markets into things which are much more commercially attractive,” Varadhachary explains.

Why did they go for the less commercially viable application first? As Varadhachary put it, “The Fannin model is to allow us to go after areas which are major unmet medical needs, even if they are not necessarily as attractive on a commercial basis.”

But betting on a less common malady could have a bigger payoff than the Allterum team originally expected.

Before the new CPRIT grant, Allterum’s funding included a previous seed grant from CPRIT of $3 million. Other funds included an SBIR grant from NCI, as well as another NCI program called NExT, which deals specifically with experimental therapies.

“To get an antibody from research into clinical testing takes about $10 million,” Varadhachary says. “It's an expensive proposition.”

With this, and other nontraditional financing, the company was able to take what Varadhachary called “a huge unmet medical need but a really tiny commercial market” and potentially help combat a raft of other childhood cancers.

“That's our vision. It's not economically hugely attractive, but we think it's important,” says Varadhachary.

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.

3 Houston innovators to know this week

who's who

Editor's note: Every Monday, I'm introducing you to three Houston innovators to know — three individuals behind recent innovation and startup news stories in Houston as reported by InnovationMap. Learn more about them and their recent news below by clicking on each article.

Atul Varadhachary, managing director of Fannin Innovation

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. Read more.

For over a year, the tech and business community has been obsessing over artificial intelligence. As Natasha Gorodetsky, the Houston-based founder and CEO of Product Pursuits, writes in a guest column about how the product management community is not an exception.

"Product managers — as well as startup founders leading a product function — more than any other role, face a challenge of bringing new life-changing products to market that may or may not be received well by their users," she writes. "A product manager’s goal is complex — bring value, stay ahead of the competition, be innovative. Yet, the "behind the scenes" grind requires endless decision making and trade offs to inspire stakeholders to move forward and deliver."

She continues in her article to outline the trends of AI for product management. Read more.

Diakonos Oncology has recently made major headway with the FDA, including both a fast track and an orphan drug designation. It will soon start a phase 2 trial of its promising cancer fighting innovation.

The therapy catalyzes a natural immune response, it’s the patient’s own body that’s fighting the cancer. Hartenbach credits Decker with the idea of educating dendritic cells to attack cancer, in this case, glioblastoma multiforme (GBM), one of the most aggressive cancers with which doctors and patients are forced to tangle.

“Our bodies are already very good at responding very quickly and aggressively to what it perceives as virally infected cells. And so what Dr. Decker did was basically trick the immune system by infecting these dendritic cells with the cancer specific protein and mRNA,” details COO Jay Hartenbach. Read more.

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 engineers develop breakthrough device to advance spinal cord treatment

future of health

A team of Rice University engineers has developed an implantable probe over a hundred times smaller than the width of a hair that aims to help develop better treatments for spinal cord disease and injury.

Detailed in a recent study published in Cell Reports, the probe or sensor, known as spinalNET, is used to explore how neurons in the spinal cord process sensation and control movement, according to a statement from Rice. The research was supported by the National Institutes of Health, Rice, the California-based Salk Institute for Biological Studies, and the philanthropic Mary K. Chapman Foundation based in Oklahoma.

The soft and flexible sensor was used to record neuronal activity in freely moving mice with high resolution for multiple days. Historically, tracking this level of activity has been difficult for researchers because the spinal cord and its neurons move so much during normal activity, according to the team.

“We developed a tiny sensor, spinalNET, that records the electrical activity of spinal neurons as the subject performs normal activity without any restraint,” Yu Wu, a research scientist at Rice and lead author of the study said in a statement. “Being able to extract such knowledge is a first but important step to develop cures for millions of people suffering from spinal cord diseases.”

The team says that before now the spinal cord has been considered a "black box." But the device has already helped the team uncover new findings about the body's rhythmic motor patterns, which drive walking, breathing and chewing.

"Some (spinal neurons) are strongly correlated with leg movement, but surprisingly, a lot of neurons have no obvious correlation with movement,” Wu said in the statement. “This indicates that the spinal circuit controlling rhythmic movement is more complicated than we thought.”

The team said they hope to explore these findings further and aim to use the technology for additional medical purposes.

“In addition to scientific insight, we believe that as the technology evolves, it has great potential as a medical device for people with spinal cord neurological disorders and injury,” Lan Luan, an associate professor of electrical and computer engineering at Rice and a corresponding author on the study, added in the statement.

Rice researchers have developed several implantable, minimally invasive devices to address health and mental health issues.

In the spring, the university announced that the United States Department of Defense had awarded a four-year, $7.8 million grant to the Texas Heart Institute and a Rice team led by co-investigator Yaxin Wang to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation.

That same month, the university shared news that Professor Jacob Robinson had published findings on minimally invasive bioelectronics for treating psychiatric conditions. The 9-millimeter device can deliver precise and programmable stimulation to the brain to help treat depression, obsessive-compulsive disorder and post-traumatic stress disorder.

Houston clean hydrogen startup to pilot tech with O&G co.

stay gold

Gold H2, a Houston-based producer of clean hydrogen, is teaming up with a major U.S.-based oil and gas company as the first step in launching a 12-month series of pilot projects.

The tentative agreement with the unnamed oil and gas company kicks off the availability of the startup’s Black 2 Gold microbial technology. The technology underpins the startup’s biotech process for converting crude oil into proprietary Gold Hydrogen.

The cleantech startup plans to sign up several oil and gas companies for the pilot program. Gold H2 says it’s been in discussions with companies in North America, Latin America, India, Eastern Europe and the Middle East.

The pilot program is aimed at demonstrating how Gold H2’s technology can transform old oil wells into hydrogen-generating assets. Gold H2, a spinout of Houston-based biotech company Cemvita, says the technology is capable of producing hydrogen that’s cheaper and cleaner than ever before.

“This business model will reshape the traditional oil and gas industry landscape by further accelerating the clean energy transition and creating new economic opportunities in areas that were previously dismissed as unviable,” Gold H2 says in a news release.

The start of the Black 2 Gold demonstrations follows the recent hiring of oil and gas industry veteran Prabhdeep Singh Sekhon as CEO.

“With the proliferation of AI, growth of data centers, and a national boom in industrial manufacturing underway, affordable … carbon-free energy is more paramount than ever,” says Rayyan Islam, co-founder and general partner at venture capital firm 8090 Industries, an investor in Gold H2. “We’re investing in Gold H2, as we know they’ll play a pivotal role in unleashing a new dawn for energy abundance in partnership with the oil industry.”
