Houston-based clinical-stage biotechnology company Coya Therapeutics (NASDAQ: COYA) has raised $11.1 million in a private investment round.

India-based pharmaceuticals company Dr. Reddy’s Laboratories Inc. led the round with a $10 million investment, according to a news release. New York-based investment firm Greenlight Capital, Coya’s largest institutional shareholder, contributed $1.1 million.

The funding was raised through a definitive securities purchase agreement for the purchase and sale of more than 2.5 million shares of Coya's common stock in a private placement at $4.40 per share.

Coya reports that it plans to use the proceeds to scale up manufacturing of low-dose interleukin-2 (IL-2), which is a component of its COYA 302 and will support the commercial readiness of the drug. COYA 302 enhances anti-inflammatory T cell function and suppresses harmful immune activity for treatment of Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Dementia (FTD), Parkinson’s disease and Alzheimer’s disease.

The company received FDA acceptance for its investigational new drug application for COYA 302 for treating ALS and FTD this summer. Its ALSTARS Phase 2 clinical trial for ALS treatment launched this fall in the U.S. and Canada and has begun enrolling and dosing patients. Coya CEO Arun Swaminathan said in a letter to investors that the company also plans to advance its clinical programs for the drug for FTD therapy in 2026.

Coya was founded in 2021. The company merged with Nicoya Health Inc. in 2020 and raised $10 million in its series A the same year. It closed its IPO in January 2023 for more than $15 million. Its therapeutics uses innovative work from Houston Methodist's Dr. Stanley H. Appel.

How does a historic university maintain its legacy while still making room for growth and increased opportunities? That's what Rice University President Reginald DesRoches considers with every decision he makes.

"It's this idea of preserving what's special about the university, while also knowing we need to adapt to a new time, a new Rice, a new time in higher ed, and a new time in society," DesRoches says on the Houston Innovators Podcast.

"There's a healthy tension between preserving what Rice is known for — the culture of care, the close-knit community — while knowing that we need to grow, have a global impact, and position Rice on a global scale. It's something that's constantly in my mind to make sure we do both." Continue reading.

Chronic Kidney Disease is expensive and common. In fact, 37 million Americans live with the condition. The winner of this year’s Houston Innovation Award for best female-founded business, Koda Health, recognized the need for help among CKD sufferers and has answered the call.

Last week, Koda Health announced the addition of Kidney Action Planning to its suite of services for patients with serious illnesses.

"Kidney Action Planning is designed to fill a significant void in CKD management," Tatiana Fofanova, CEO of Koda Health, says in a statement. "Some studies indicate greater than 70 percent of patients start dialysis in the ER suboptimally, potentially navigating a life-or-death scenario. This is both frightening and largely avoidable with an intervention like Kidney Action Planning, which helps patients better understand CKD.” Continue reading.

New CEO brings strategic vision to Houston co. advancing neurodegenerative disease treatments

Q&A

Coya Therapeutics has named a new CEO. As of Nov. 1, Arun Swaminathan replaced Co-founder Howard Berman in the role. Berman has assumed the title of executive chairman, in which he will still remain active with the company.

Swaminathan started with Coya two years ago as chief business officer. This transition was planned, says the PhD-holding scientist and businessman.

“(Berman's) intent was that it was the right time to put in place a CEO that, as we move into the operational phases of the company, that can take the reins from him,” he tells InnovationMap.

Coya Therapeutics is a publicly traded biotechnology company that is working on two novel treatments for Alzheimer's disease. Coya's therapeutics, which are currently in trials, use regulatory T cells (T regs) to target both systemic- and neuroinflammation in patients.

InnovationMap: Berman has been a very visible CEO. Will you follow suit?

Arun Swaminathan: I think it's part of the CEO’s job to be visible and to communicate the value of our company to all the stakeholders out there. So yes, I do plan to be visible as well. Obviously, Howard as the founder had elements that he talked about, the foundational stories. I obviously will be doing less of that.

IM: What was your journey from the lab to the boardroom?

AS: I have a PhD from the University of Pittsburgh. I like to say that I grew up at Bristol Myers Squibb, so I started in a clinical pharmacology group at BMS, running clinical trials, but in the cardiovascular and metabolic space.

What happened was, as I was the study director on a diabetes trial there, and the data starts coming in for these early diabetic trials, and I got highly involved with the commercial folks at BMS in starting to plan out “What does the target profile look like? How is this going to play out in the real world?” You know, the marketing teams and commercial teams start engaging when clinical data is available, because they're starting to plan for the eventual launch of the product.

That gave me a lot of exposure to the commercial side of things, and I also got a lot of experience presenting to opinion leaders and others through that role. And I said, “What I really love is that intersection between science and business.” And so I think that was my moment.

Then I moved to business development and licensing, where I helped scan the universe for assets and talk to CEOs of companies like Coya as a junior person, trying to understand if there's something that we can bring into BMS to strengthen the pipeline of BMS. So that gave me exposure to deals, how deals are structured, how you negotiate a lot of that kind of stuff.

Then I said, “Look, if I want to be a complete person in biotech, I do need to go into more true commercial roles.” So I went into commercial strategy. I was involved in the commercial strategy for what is now known as Eliquis. Was back then known as apixaban. That’s still the generic name.

Then I led marketing for Orencia, a rheumatoid arthritis drug. So I went and got both strategic and tactical marketing experience at BMS, and then I used all of that experience, rounded up. I eventually ended up co-founding a company, and that's led me to the last nine years with smaller biotech companies. So that's my evolution and path. But I think my true moment of realization was about three years into my clinical role at BMS, when I said, what I really enjoy is translating good science into commercial value, and I think that's what excites me.

IM: Why is Houston an important part of Coya's success?

AS: It is important that Coya stays in Houston, because we have a very close association with Houston Methodist, we get a lot of our work, our early research work still done through Houston Methodist, through Dr. [Stanley] Appel's lab and through other experts. We absolutely have a special research agreement with Houston Methodist, so we have a very strong reason to be in Houston. So, we do not anticipate moving out of Houston.

Houston company with revolutionary neurodegenerative disease treatment shares milestones since IPO

ring that bell

After announcing its initial public offering earlier this year, a Houston therapeutics company has celebrated the milestone and announced recent growth as well.

Coya Therapeutics (Nasdaq: COYA) rang the closing bell last week. The clinical-stage biotech company, which has developed a biologics therapy that prevents further spreading of neurodegenerative diseases by making regulatory T cells functional again, announced the closing of its $15.25 million IPO in January.

"We launched our IPO into one of the toughest biotech capital markets in recent memory and are enormously grateful to all our investors for the confidence they then showed in our prospects," says Howard Berman, CEO and chairman of Coya, in a June 12 letter to stockholders. "I believe that to date, we’ve executed strongly against the goals we then established, and I remain excited about our future."

In the letter, Berman shares some of the recent clinical successes from two treatments — COYA 302, a treatment for ALS, and COYA 301, a treatment for Alzheimer’s Disease. Both treatments have seen strong clinical proof of concept data in the respective open-label studies.

Earlier this year, Coya expanded its C-suite to include Dr. Arun Swaminathan as chief business officer. He has over 20 years of hands-on health care business executive experience. Prior to Coya, Swaminathan served in the same role for Actinium Pharmaceuticals.

"Arun is actively engaged in exploring potential strategic opportunities across our portfolio of assets as we believe successful partnering efforts have the potential to enhance our scientific bona fides, leverage our technology into new areas of unmet medical need, and importantly, possibly secure upfront fees and associated non-dilutive funding," Berman writes in the letter. "We look forward to pursuing additional value creation catalysts that further highlight our entrepreneurialism and ability to execute, while maintaining focus on our core assets."

The latest addition to the Coya team is Guillaume Dorothée, who joins the company's scientific advisory board. A leading expert on the role that the immune system and peripheral-central immune crosstalk play in the pathophysiology of Alzheimer's, he's a tenured research director and team head in neuroimmunology at the French National Institute of Health and Medical Research in Paris.

“I am glad and honored to join such eminent scientists on the prestigious SAB of Coya Therapeutics," he says in a June 5 statement from Coya. "I am fully convinced that innovative Treg-based immunomodulatory approaches, as developed by Coya, are highly promising therapeutic strategies for the treatment of neurodegenerative disorders and other neuroinflammatory conditions. I will be happy to help Coya Therapeutics in this exciting endeavor.”

Recently, Berman joined the Houston Innovators Podcast to discuss Coya's mission and plan post IPO.

2 Houston suburbs rank among 10 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

  • No. 1 – Midland, Michigan
  • No. 2 – Homosassa Springs, Florida
  • No. 3 – Weirton, West Virginia
  • No. 4 – The Woodlands
  • No. 5 – Spring, Texas
  • No. 6 – Rio Rancho, New Mexico
  • No. 7 – Altoona, Pennsylvania
  • No. 8 – Paducah, Kentucky
  • No. 9 – Lynchburg, Virginia
  • No. 10 – Palm Coast, Florida

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.
