Houston-based Tvardi Therapeutics and Cara Therapeutics announced the companies have entered into a definitive merger agreement to combine in an all-stock transaction. Once completed, Houston will house the headquarters.

Tvardi is a clinical-stage biopharmaceutical company that focuses on the development of novel, oral, and small molecule therapies that target STAT3 to treat fibrosis-driven diseases. Tvardi will merge with a wholly owned subsidiary of Cara.

Once complete, the pre-merger Cara Therapeutics stockholders are expected to own approximately 17 percent of the combined company and pre-merger Tvardi Therapeutics investors are expected to own 83 percent of the combined company. Prior to adjustment from the issuance of the shares in the recently completed Tvardi financing and assuming Cara, which went public in 2014, has net cash at closing of between $22.9 million and $23.1 million with the percentage of the combined company that pre-merger Cara stockholders and pre-merger Tvardi stockholders will own upon the closing of the merger, which is subject to further adjustment if Cara’s net cash balance falls outside of the range.

“As we approach meaningful value inflection points next year, including two Phase 2 readouts of our lead program in idiopathic pulmonary fibrosis, followed by the readout in our hepatocellular carcinoma program, this merger, the recently completed financing, and becoming a publicly traded company give us access to the critical funding required to further advance our promising pipeline programs that address significant unmet needs,” Imran Alibhai, CEO of Tvardi Therapeutics, says in a news release.

Also, Tvardi has completed an approximately $28 million private financing from a syndicate of new and existing institutional investors. With the cash from both companies at closing and the proceeds of this financing, the post-merger company plans to have cash to fund its operating expenses and capital expenditure requirements into the second half of 2026.

“I am grateful to the Cara Board, leadership team, and shareholders who share our vision of Tvardi that is well-positioned to introduce effective, new treatment options to patients suffering from serious, chronic, fibrosis-driven diseases,” Alibhai continues.

In 2021, Tvardi emerged from stealth and closed a $74 million series B funding round led by New York-based Slate Path Capital, Florida-based Palkon Capital, Denver-based ArrowMark Partners, and New York-based 683 Capital, with continued support and participation by existing investors, including Houston-based Sporos Bioventures.

fresh funds

A Houston-based clinical-stage biopharmaceutical company has raised millions in its latest round.

Tvardi Therapeutics Inc. closed its $74 million series B funding round led by new investors New York-based Slate Path Capital, Florida-based Palkon Capital, Denver-based ArrowMark Partners, and New York-based 683 Capital, with continued support and participation by existing investors, including Houston-based Sporos Bioventures.

"We are thrilled to move out of stealth mode and partner with this lineup of long-term institutional investors," says Imran Alibhai, CEO at Tvardi. "With this financing we are positioned to advance the clinical development of our small molecule inhibitors of STAT3 into mid-stage trials as well as grow our team."

Through Slate Path Capital's investment, Jamie McNab, partner at the firm, will join Tvardi's board of directors.

"Tvardi is the leader in the field of STAT3 biology and has compelling proof of concept clinical data," McNab says in the release. "I look forward to partnering with the management team to advance Tvardi's mission to develop a new class of breakthrough medicines for cancer, chronic inflammation, and fibrosis."

Tvardi's latest fundraise will go toward supporting the company's products in their mid-stage trials for cancer and fibrosis. According to the release, Tvardi's lead product, TTI-101, is being studied in a Phase 1 trial of patients with advanced solid tumors who have failed all lines of therapy. So far, the drug has been well-received and shown multiple durable radiographic objective responses in the cancer patients treated.

Dr. Keith Flaherty, who is a member of Tvardi's scientific advisory board and professor of medicine at Harvard Medical School, offered his support of the company.

"STAT3 is a compelling and validated target. Beyond its clinical activity, Tvardi's lead molecule, TTI-101, has demonstrated direct downregulation of STAT3 in patients," he says in the release. "As a physician, I am eager to see the potential of Tvardi's molecules in diseases of high unmet medical need where STAT3 is a key driver."

JLABS-based cancer therapies company closes $15.5M series A led by Houston bioventure

fresh funds

Houston-based Stellanova Therapeutics closed a $15.5 million series A financing this month, which will advance the company's first-in-human clinical trials for oncology and help build out its team.

Stellanova is a resident company at Johnson & Johnson's biotech incubator in the TMC (JLABS @ TMC) and is one of four entities that make up cancer and disease biotech company Sporos Bioventures, which officially launched last month after closing a $38.1 million series A of its own.

Stellanova is focused on advancing therapies for cancers that are resistant to current treatments, like chemotherapy and immune therapies. According to a release, it has seen unprecedented anti-tumor activity in preclinical models of pancreas and triple negative breast cancer through the use of its lead antibody, which targets DKK3, a factor secreted by cancer-associated fibroblasts that spur tumors.

The company was founded based on research out of Dr. Rosa Hwang's lab at Houston's MD Anderson Cancer Center.

"We are thrilled to bring Stellanova into the Sporos group of companies. Stellanova means 'new star,' and it is clear the Stellanova team embraces this namesake with their entirely new approach to treating cancer," Harold Levy, Stellanova and Sporos founder and board member said in the statement. "We have been impressed by Stellanova's accomplishments and look forward to being involved in the advancement of the company's platform, one that we believe has the potential to directly combat the most devastating of cancers."

In conjunction with the financing, Stellanova also announced that it has named JLABS @ TMC founding team member Emmanuelle Schuler as the company's inaugural CEO.

Stellanova joins Sporos's Tvardi Therapeutics as it moves toward clinical trials. Tvardi, named a "most promising" by BioHouston and the Rice Alliance in December, is in Phase 1 clinical trial of its STAT3 oral inhibitor for treatment of cancer, inflammation and fibrosis.

Asylia Therapeutics and Nirogy Therapeutics were also founding entities of Sporos. The companies are in the proof of concept and discovery phases and focus on cancer, autoimmune diseases, infectious diseases, and inflammatory diseases.

Houston-based cancer and disease bio-venture launches after $38.1M series A

money moves

Sporos Bioventures LLC launched this month after closing a $38.1 million round of series A financing.

The Houston-based biotech company aims to accelerate the development of breakthrough therapies for cancer and immune diseases by sharing resources, capital, access to clinical trial infrastructure, and talent from within its knowledgeable team of biotech executives, entrepreneurs, academic scholars, and investors. The company was launched with four entities: Tvardi Therapeutics, Asylia Therapeutics, Nirogy Therapeutics, and Stellanova Therapeutics.

The most advanced of the four entities, Tvardi, is currently in Phase 1 clinical trial to evaluate it's STAT3 oral inhibitor. It was named a "most promising" life sciences company at the 2020 Texas Life Science Forum, hosted by BioHouston and the Rice Alliance in December. The remaining entities are in the development stages and are focused on cancer, autoimmune disease, fibrosis, and tumor growth, among other conditions.

"Sporos was founded to accelerate the development of new medicines by addressing inefficiencies and risk in the establishment of new biotech companies," Peter Feinberg, Sporos co-founder, said in a statement. "By leveraging our extensive network, including the Texas Medical Center, we first identify transformative scientific opportunities and then deploy our top-tier talent, funding, and operational support to drive these insights into a growing pipeline of first-in-class treatment options."

In conjunction with the launch, Sporos named Michael Wyzga as the company's founding CFO. Wyzga was previously CFO at Genzyme for 12 years and has held various senior-level positions in the industry.

"By strategically deploying valuable resources to young companies that would not typically be supported by top-tier seasoned talent and infrastructure, we believe that we can efficiently bring a diverse set of therapies through clinical development," Wyzga said in a statement. "I am thrilled to join a team with decades of scientific and operational expertise and look forward to guiding our strategic and financial growth."

Wyzga joins a team of seasoned leaders in the biotech and cancer research fields, including Dr. Ronald DePinho, professor of Cancer Biology and past president of MD Anderson, who will serve as the chair of Sporos' Strategic Advisory Council. Jeno Gyuris, a biotech executive in oncology drug discovery and development with more than 25 years of experience, will serve as chief science officer. And Alex Cranberg, an experienced active early-stage biotech investor, serves as director.

Houston Innovation Awards honor Don Kendall Jr. with posthumous​ Trailblazer Legacy Award

lasting legacy

Every year, the Houston Innovation Awards honor one Houstonian with the Trailblazer Award, whose impact is felt throughout the city's innovation and business ecosystem.

This year, the Trailblazer Legacy Award will be given posthumously to Don Kendall Jr., who died in September while on a trip to the Republic of the Congo with the Jane Goodall Institute, one of the many organizations he was deeply involved with.

Kendall's obituary puts it simply: "Don’s truest passions were conservation and his family." Many saw those passions play out in his career, particularly in the role he played in shaping Houston's clean energy sector.

Kendall served as general partner of New Climate Ventures, a Houston-based early-stage venture capital firm that invests in next-gen energy, materials and fuel technologies and startups. The firm's portfolio includes Houston-based clean energy companies like Solidec, Syzygy Plasmonics and Rheom Materials.

Kendall was also founding managing director and CEO of Kenmont Capital LP. He ran a $500 million distressed debt and credit-based hedge fund focused on the energy, power and transportation sectors and one of the top-performing private equity funds under the Kenmont umbrella.

He served on the board of Talos Energy, American Midstream Partners, Syzygy Plasmonics, Tangent Energy, Stream Energy and others. Notably, he served as Chair of the Special Committee of the SolarCity board during its acquisition by Tesla in 2016. According to his obituary, Kendall negotiated with "Elon Musk in the middle of the night on a rickety pier in Indonesia after eluding a poisonous snake."

Outside of the clean energy space, Kendall also served on the boards of the Jane Goodall Institute, Earthwatch International and Ecological Defense Group. He also served as vice chair of the Houston Zoo Inc. and chair of its Conservation Committee.

Kendall was selected by our esteemed panel of judges to receive the 2026 Trailblazer Legacy Award. The panel includes carbon removal entrepreneur and CEO of Houston-based Mars Materials Aaron Fitzgerald.

Fitzgerald shares the profound impact Kendall had on his career and those of many others.

"Honoring Don with the Trailblazer Legacy Award is a fitting tribute to a leader whose impact spanned civic work with the Houston Zoo, wildlife conservation, and the growth of our startup ecosystem," Fitzgerald says. "He paired a keen eye for potential with the relentless drive to unlock it. For Mars Materials, his early backing carried us through a critical valley when we needed belief the most, and his presence as a personal mentor is profoundly missed."

Don was an avid traveler, cyclist and collector. He is survived by his wife of 50 years, Diane S. Kendall. A celebration of life will be held early in 2027.

2 Houston suburbs rank among 5 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.
