A Houston organization devoted to developing early-stage therapeutic and medical device technologies announced fresh funding for one of its startups.

Fannin Partners' Goldenrod Therapeutics, received a $320,000 Phase I SBIR grant from the National Institute on Drug Abuse (NIDA) for studies regarding both addiction medicine and neurodegenerative diseases with a single lead candidate, called 11h.

The grant will fund studies in rodent models of methamphetamine addiction and the efficacy of 11h for the tiny patients. This is the next step in charting the established promise of 11h in substance use disorders using animal models. Existing therapies for opioid and alcohol addiction have high relapse rates, and there are currently no FDA-approved medications for Stimulant Use Disorders (StUDs).

Previous preclinical studies demonstrated that 11h was effective in the fight against cocaine addiction. The goal is to note similar results in methamphetamine addiction.

At the same time, Fannin was also granted a $250,000 Early Hypothesis Development Award from the Department of Defense (DoD) to study 11h in neurodegenerative diseases. Specifically, the funds will be used to work on rodent models of multiple sclerosis (MS).

Fannin’s goal is to develop an oral medication that slows or reverses the progression of MS, while also improving the patient’s quality of life by relieving symptoms. Many MS medications come with the threat of liver injury and increased risk of infection, so sidestepping those is also a hope for 11h.

In fact, 11h was developed to minimize the toxicities associated with existing PDE4 inhibitors. Early evidence shows that the drug is not only effective, but also safe and easily tolerable.

“NIDA’s continued support of our SUD program highlights the potential of 11h to significantly improve the standard of care for patients suffering from these conditions, some of which lack any approved pharmaceutical options," says Dr. Atul Varadhachary, managing partner at Fannin, in a news release. “The additional DoD funding will allow us to explore 11h’s impact on neurodegenerative disease, as well. We are grateful for the support from both organizations as we advance 11h towards clinical development.”

Previous steps in 11h’s development were funded by a $350,000 Phase I SBIR grant from NIDA. 11h is part of NIDA’s Addiction Treatment Discovery Program. Next year, Fannin will likely scale up Good Manufacturing Practices (GMP) production and complete toxicology studies. This will lead to clinical trials for 11h for cocaine use disorder and other StUDs. But don’t expect Fannin to be quiet for long. Its next big discovery is always on the horizon.

Exclusive: 2 Houston health care institutions team up to develop cancer-fighting treatments

collaboration station

Two Houston organizations announced a new collaboration in a major move for Houston’s biotech scene.

Fannin Partners and the University of Texas MD Anderson Cancer Center have teamed up to develop drugs based on Raptamer, the creation of Fannin company Radiomer Therapeutics.

“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, Varadhachary, explained to InnovationMap in May. “We are deploying this unique platform to develop novel therapies against attractive first-in-class oncology targets.”

The pairing of Fannin and MD Anderson makes perfect sense. Researchers at the institution have already identified novel markers that they will target with both Raptamer-based drugs and radiopharmaceutical/radioligand therapies.

“MD Anderson and Fannin bring highly complementary capabilities to the identification of novel cancer targets and Raptamer-based drug discovery,” says Varadhachary in a press release. “Our collaboration will enable us to rapidly develop targeted therapeutics against novel targets, which we hope will offer hope to patients with progressive cancers.”

Early in this meeting of minds, researchers will focus on developing targeted radiopharmaceuticals — the Radiomers for which Varadhachary’s company is named — as well as targeted drug conjugates that utilize Raptamers. Raptamers are an innovative class of targeting vectors that combine a DNA oligonucleotide backbone with added peptide functionality, for oncology indications.

“We are committed to exceptional research that can help us further our understanding of cancer and develop impactful therapeutic options for patients in need,” says Timothy Heffernan, Ph.D., vice president and head of therapeutics discovery at MD Anderson. “Fannin’s Raptamer drug discovery platform represents an innovative new modality that offers the potential to enhance our portfolio of novel therapies, and we look forward to the opportunities ahead.”

Fannin and MD Anderson will design translational studies together and collaborate to select promising targets for drug discovery. This is a great deal for Fannin, which will retain commercialization rights for the assets that are developed. But MD Anderson won’t be left out; the institution is eligible to receive some payments based on the success of Radiomers and other Raptamer-based drugs developed through the collaboration.

Earlier this year, Varadhachary joined the Houston Innovators Podcast to discuss Fannin's innovation approach and contribution to medical development in Houston. Listen to the episode below.

Early-stage cancer-fighting startup raises pre-seed, launches under Houston life science leader

ready to grow

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 doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
