Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.

How a Houston company is fighting anxiety, insomnia & Alzheimer’s through waveforms

mental health

A Houston-based company is taking a medicine-free approach to target brain neurologically associated with mental illness.

Nexalin Technology’s patented, FDA-cleared frequency-based waveform targets key centers of the midbrain to support the normalization of neurochemicals through a process known as Transcranial Alternating Current Stimulation (tACS). Delivered via a non-invasive device, the treatment gently stimulates the hypothalamus and midbrain, helping to “reset networks associated with symptoms” of anxiety and insomnia. Early clinical evidence suggests this approach can promote healthier brain function and improved sleep.

Through its recently appointed scientific advisory board (SAB), Nexalin also aims to target Alzheimer’s disease with a clinical development pipeline supported by published data and internal data from studies involving its proprietary DIFS technology. Nexalin’s Gen-2 SYNC and Gen-3 Halo headset delivers the DIFS, which is a waveform that can penetrate deep brain structures implicated in cognitive decline and mental illness.

The board includes experts in neurology, neuroimaging and neurodegenerative diseases with Dr. Mingxiong Huang, Dr. David Owens, and Dr. Abe Scheer coming on board. Nexalin plans to initiate new Alzheimer’s-focused clinical studies in the Q3 2025 by incorporating cognitive testing, imaging biomarkers, and guided metrics to assess treatment efficacy and neural activation.

“I am excited to work alongside Nexalin’s leadership and fellow SAB members to help guide the next generation of non-invasive neuromodulation therapies,” Huang said in a news release. “The intersection of neuroimaging, brain stimulation, and clinical science holds enormous potential for treating neurodegenerative disease.”

Recently, Nexalin’s proprietary neurostimulation device moved forward with a clinical trial that evaluated its treatment of anxiety disorders and chronic insomnia in Brazil. The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices was shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria University Hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia. The Nexalin Gen-2 15-milliamp neurostimulation device has also been approved in China, Brazil and Oman. Its Gen 1 device first received FDA clearance in 2003, according to the company's website.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population.

Nexalin previously raised $5 million through a public stock offering.

Houston regenerative medicine company expands lab for future trials

new digs

A Houston regenerative medicine company has unveiled new laboratory space with the goal of expanding its pioneering science.

FibroBiologics uses fibroblasts, the body’s most common type of cell, rather than stem cells, to help grow new cells. Fibroblasts are the primary variety of cells that compose connective tissue. FibroBiologics has found in studies that fibroblasts can be even more powerful than stem cells when it comes to both regeneration and immune modulation, meaning they could be a more versatile way forward in those fields.

In 2023, FibroBiologics moved into new lab space in the UH Technology Bridge. Now, with its new space, the publicly traded company, which has more than 240 patents issued or pending, will be even better equipped to power forward with its research.

The new space includes more than 10,000 square feet of space devoted to both labs and offices. The location is large enough to also house manufacturing drug product candidates that will be used in upcoming trials. Additionally, the company reports that it plans to hire additional researchers to help staff the facility.

“This expansion marks a transformative step forward for our company and our mission,” Pete O’Heeron, FibroBiologics founder and CEO, said in a news release. “By significantly increasing the size of our lab, we are creating the space and infrastructure needed to foster greater innovation and accelerate scientific breakthroughs.”

The streamlined, in-house manufacturing process will reduce the company’s reliance on external partners and make the supply chain simpler, O’Heeron added in the release.

Hamid Khoja, the chief scientific officer for FibroBiologics, also chimed in.

“To date, our progress in developing potentially transformative therapeutic candidates for chronic diseases using fibroblasts has been remarkable,” he added in the release. “This new laboratory facility will enable further expansion and acceleration of our research and development efforts. Additionally, the expansive new space will enable us to bring in-house currently outsourced projects, expand our science team and further contribute to the increased efficiency of our R&D efforts.”

This news arrives shortly after a milestone for the company in its research about neurodegenerative disease. Last month, fibroblast treatments in an animal model study demonstrated a notable regeneration of the myelin sheath, the layer that insulates nerves and is worn down by disease.

“Confirming remyelination in a second validated animal model is an important step in our research and development efforts, offering fresh hope for patients with demyelinating diseases, including multiple sclerosis,” O’Heeron added in a separate release. “These findings advance our mission to develop transformative fibroblast-based therapies that address the root causes of chronic disease, not just their symptoms, and reflect our dedication to pushing the frontiers of regenerative medicine."

How this Houston innovator is using his personal connection to ALS fuel his fight for a cure

guest column

We can never predict how our lives will turn out, but then maybe some of us can. Genetic testing showed that I, like my grandfather, aunt, uncle and father before me, would most likely die of amyotrophic lateral sclerosis, more commonly known as ALS, and/or frontotemporal degeneration (FTD) in my 40s.

Being 36, it’s possible that fear could have overtaken my life, but instead I chose to fight for every chance to change not only my life, but the lives of millions who are suffering or may one day suffer from neurodegenerative disease.

ALS is a rare disease that robs one of their ability to control their muscles, leading them to lose their ability to walk, talk and eventually breathe. Eighty percent of cases are sporadic (of unknown origin) and 20 percent have known genetic causes.

When I learned that I carried the C9ORF72 genetic variant, a causative genetic variant for ALS/FTD) my first instincts were to help others understand their status and where they could turn for help. I saw a vacuum for resources and understanding in the genetic ALS space and I knew that thousands were suffering in darkness.

Through the efforts of many, we created the first ever nonprofit – Genetic ALS & FTD: End the Legacy – focused on fighting for the genetic ALS and FTD communities. After making great strides to fight for our rights and access to care, I was asked if I could help my current CEO, Howard Berman, commercialize Dr. Stanley Appel’s regulatory T Cell (Treg) therapy for ALS.

I joined Coya Therapeutics in 2021 as the first employee, working to build a company that would one day bring life changing therapies to patients. Coya’s therapies are based on Dr. Appel’s discovery that neurodegenerative diseases drive an inflammatory response. As inflammation rises, it damages regulatory T cells, and when Tregs are damaged, inflammation becomes a persistent condition driving degeneration and eventually death.

It was at that point that my life changed from the advocacy world to the therapeutic world. Now over three years later, we are closer than ever to making a paradigm change for how patients with ALS and other neurodegenerative diseases are treated.

At Coya, we believe that combination biologics are the future of treating neurodegenerative diseases. COYA 302 is our lead asset, which has shown promising results in a proof-of-concept study released in March of 2023. We are currently working towards a double-blind, placebo-controlled trial for COYA 302 in ALS set to kick off later this year.

I never wanted to live a life so damned by disease, but when put between a rock and a hard place, the only choice is to fight. I don’t know how my life will end, but I hope that my children will know that I faced a great challenge head on with pride and resilience.

In the end, it is the combination of both the worlds I work in that lead to better outcomes for patients, raising awareness and lifesaving research. This ALS Awareness Month, please join us and our partners like the ALS Association, End the Legacy, and I AM ALS in raising awareness about these conditions, their risks, and treatment options.

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

  • 93 percent provide voter registration and/or serve as voting locations
  • 84 percent provide partnerships with local social services agencies
  • 82 percent provide job application assistance
  • 68 percent facilitate applications for government benefits
  • 38 percent provide on-site social services
  • 30 percent provide telehealth rooms and/or resources
"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."
