The Woodlands-based medical device company Autonomix Medical grossed more than $11.1 million in its recent IPO.

The company’s stock now trades on the NASDAQ market under the symbol AMIX. On February 1, company officials range the NASDAQ’s closing bell. The stock closed February 5 at $5.60 per share.

The NASDAQ listing “represents a pivotal moment in the growth of our [company] and a significant corporate milestone leading to what we believe will be an exciting future for Autonomix,” says Lori Bisson, the company’s CEO.

In the IPO, Autonomix sold nearly 2.24 million shares of common stock at $5 each. The gross amount raised excludes sales commissions and other expenses.

In a January 19 filing with the U.S. Securities and Exchange Commission (SEC), Autonomix had eyed gross IPO proceeds of more than $21.2 million — nearly half of what the company actually raised — from the sale of up to 4 million shares.

For the six-month period ended September 30, 2023, Autonomix tallied a net loss of $6.9 million and a deficit of nearly $30.5 million.

Outside investors BioStar Ventures (with a 15 percent pre-IPO stake) and Tricord Holdings (5.5 percent), according to SEC documents. Before the IPO, seven Autonomix executives and directors controlled 50.6 percent of the company’s common stock.

The first medical device being developed by Autonomix, founded in 2014, is a catheter-based microchip that the company says can detect and differentiate neural signals with about 3,000 times greater sensitivity than current technology.

On its website, Autonomix cites a potential $100 billion global market for its technology.

Initially, Autonomix’s technology is geared toward treating pain stemming from pancreatitis and pancreatic cancer. Other uses for the technology, protected by dozens of patents, include management of post-surgery pain, treatment of high blood pressure, and treatment of organ-related conditions.

A day after the January 29 IPO, Autonomix announced it had wrapped up an $8 million all-stock deal to regain exclusive worldwide rights for use of its technology in the cardiology sector. In December 2021, Autonomix granted a license to Impulse Medical for use of its technology for cardiac purposes. In exchange for 1.6 million Autonomix shares, Impulse sold back those rights to Autonomix.

“Regaining the cardiology rights to our innovative technology broadens our development opportunities and provides further optionality related to our development strategy moving forward. Looking ahead, we remain focused on our pancreatic cancer pain development program and are on track to commence our first-in-human clinical study this quarter,” Bisson says.

Autonomix says its catheter-based sensing technology is designed to sense neural signals associated with pain or disease and then target those nerves for treatment.

“Autonomix believes this technology is a better alternative to the current approaches commonly used today, where doctors either rely on systemic drugs like opioids that lose effectiveness,” say the company, “and have unwanted side effects or treat suspected areas blindly in hopes of hitting the right nerves, an approach that is often inaccurate and can miss the target and even cause collateral damage to surrounding parts of the body.”

Houston regenerative medicine company to IPO, move toward more human trials

ready to list

Want a piece of one of Houston’s most promising biotech companies? On January 31, FibroBiologics will begin the trading of its common stock on the Nasdaq stock exchange.

While most labs in the realm of regenerative medicine are focused on stem cells, FibroBiologics has bet on fibroblasts as the secret to treating myriad ailments. Fibroblasts, the most common type of cell in the body, are the primary cells that compose connective tissue.

Interested investors can find a prospectus to peruse before taking the leap. FibroBiologics filed with the U.S. Securities & Exchange Commission (SEC) on November 7, 2023. In September, FibroBiologics CEO Pete O’Heeron told InnovationMap, “I think what we're going to see is that fibroblasts are going to end up winning... They're just a better overall cell than the stem cells.”

O’Heeron was first exposed to the possibilities of fibroblasts as a means of regrowing discs in the spine. Since starting the company in 2008 as SpinalCyte, O’Heeron and FibroBiologics have organically written and filed more than 320 patents. Potential treatments go far beyond spinal surgery to include wound care, cancer, and multiple sclerosis.

According to O’Heeron, the goal in going public is to raise capital for human trials.

“We’ve had really fantastic results with animals and now we’re ready for humans,” he explained in September. “We've done small human trials, but we haven't done the large ones that are going to get the commercialization approval from the FDA.”

FibroBiologics is growing with impressive speed. O’Heeron told us that he is hiring as quickly as he is able to find qualified scientists with the expertise to do the one-of-a-kind work required. The company opened a new lab last fall at the UH Technology Bridge, Newlin-Linscomb Lab for Cell Therapies. With its new status as a publicly traded company, FibroBiologics is primed to break even more ground.

Houston researchers develop dissolvable implant for targeted cancer drug delivery

cancer research

Researchers at Houston Methodist have developed a biodegradable implant that can be used to safely and consistently deliver drug treatments to tumors and then dissolve without the need for further surgery.

The implant is only the size of a grain of rice, but its potential is staggering. The biodegradable nanofibrous drug-eluting seed (b-NDES) works as a reservoir parked inside a soft tumor, where it can slowly release immune-stimulating drugs over time. This overcomes a consistent problem with drugs such as immune checkpoint inhibitors. Normal systemic administration sees comparatively little of the drug making its way to the tumor, with most of it circulating throughout the body. The b-NDES is like deploying a small guerrilla fighting force embedded in enemy territory, doing maximum damage to the entrenched tumor.

"To improve cancer treatment, we're trying to start a fire inside the tumor itself," Corrine Chua, associate professor in the Center for BioNanoengineering at Houston Methodist Research Institute, said in a news release. "By activating immune cells directly within the tumor microenvironment, those cells can then travel throughout the body and seek out cancer wherever it exists. The b-NDES platform was developed to help keep therapeutic drugs concentrated inside tumors while minimizing exposure to healthy tissues.”

Chua co-led the study with Alessandro Grattoni, chair and director of the Center for BioNanoengineering at Houston Methodist Research Institute.

The study included support from the Nancy Owens Breast Cancer Foundation and the National Institutes of Health/National Cancer Institute.

Chau and Grattoni used preclinical models of triple-negative breast cancer, an aggressive form of cancer that is estrogen receptor-negative, progesterone receptor-negative and HER2-negative. Because of the receptor negativity, some popular treatments like tamoxifen and trastuzumab are ineffective. Chemotherapy has been shown to be the best course of action.

The b-NDES implant is deployed alongside radiation drugs. It keeps the drugs focused on the tumor, reducing the amount of harmful side effects typically seen when drugs are circulated more widely in the body. In 60 percent of the models, tumors were eliminated and did not cause side effects beyond the tumor site. Once the drugs have been deployed, the implant breaks down naturally.

While promising, more research will have to be done to expand use to other tumor types.

"Although the study focused on triple-negative breast cancer models, the approach could have broader applications for solid tumors," Grattoni added in the release. "It could potentially be used in cancers where there is a tumor lesion accessible for placement, including pancreatic or lung cancers."

New Houston platform Same Day Reels launches for on-demand content creation

In The Moment

If an event doesn't happen on Instagram, did it even really happen? In today's social media-driven age of branding and audience engagement, the answer increasingly is no.

Houston entrepreneur Karen De Amat is looking to fill the online content creation needs of companies with her new venture, Same Day Reels, which launched in early August. It will serve as a platform to connect companies and brands with talent that can help turn an event into a viral moment as it is happening.

"Events move quickly, and social media moves even faster,” said De Amat. “Same Day Reels was built to help brands capture the moment while it still matters. We are creating a more efficient way for businesses and creators to work together. Brands need content faster, and creators need more opportunities to turn their talent into real work. Same Day Reels brings those needs together.”

The company is focused on adding livestreams and concurrent short video content to "activations, launches, fundraisers, grand openings, conferences, hospitality experiences, and private celebrations." Such content can significantly increase the visibility of a product or brand according to digital marketing brands like Wyzowl, whose data found 63 percent of people in 2026 prefer to learn about new products via short video.

Packages offered by Same Day Reels will include filming, editing, and publishing content within hours of the targeted event.

De Amat says that her content creation platform will be a way to preserve the excitement of events and launches by enshrining them with immediate social media-driven memories.

“Event content is no longer just something you post after the fact,” De Amat said. “It is part of how people experience, remember and share the moment.”

Previously, De Amat is also the founder and CEO of Social Behavior, an influencer marketing company she launched from her home in 2014. It quickly garnered an array of clients and thrust De Amat into the spotlight, including numerous appearances on Fox 26's The Isiah Factor. Influencer Marketing Hub named her one of the top CEOs of influencer marketing companies in Houston in 2025.
