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.

Cancer-fighting company based in Houston emerges from stealth and snags $74M in its latest round

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.

Abbott assembles expert team to help lure U.S. Space Academy to Texas

space race

State Rep. Greg Bonnen of Friendswood has been tapped to lead a new team that will promote Texas as the future home of the U.S. Space Academy.

Bonnen, a neurosurgeon, chairs Houston Physicians’ Hospital and the powerful Texas House Appropriations Committee. His House district is close to NASA’s Johnson Space Center.

Gov. Greg Abbott appointed the seven-member team. Last month, President Trump signed an executive order establishing the Presidential Commission on the U.S. Space Academy. Commission members, who held their first meeting this month, will recommend a permanent location for the academy.

Texas officials are pushing a site near Johnson Space Center to host the academy. Alabama, Colorado and Florida are among Texas’ competitors.

In a joint statement, U.S. Sen. Ted Cruz and U.S. Rep. Brian Babin, both of Texas, issued a statement backing the state’s bid for the academy. Cruz lives in Houston. Babbin lives in Woodville, about 55 miles south of Beaumont.

“America’s space program is built across the country, but Texas is where the pieces come together,” the lawmakers said. “We are ready to lead the next generation of space pioneers and look forward to showing why Texas is the right home for the U.S. Space Academy.”

The academy’s curriculum will include technical education, leadership development and public service components. Graduates will be set up for careers in the U.S. military, civil service, and aerospace sectors.

The Abbott-appointed team will work with the Texas Space Commission to prepare the state’s proposal for the academy.

In addition to Bonnen, team members with ties to Houston include:

  • Robert Ambrose, who grew up in Houston. He worked at Johnson Space Center before becoming associate director of the Texas A&M Space Institute.
  • Former NASA astronaut Nancy Curry-Gregg, director of the Texas A&M Space Institute. She earned a doctoral degree from the University of Houston and previously worked at Johnson Space Center.
  • Former NASA astronaut Jack Fischer, senior vice president of Houston-based Intuitive Machines. The company builds spacecraft, delivers payloads to the moon and launches satellites.

“Texas is the home of America’s human spaceflight program,” Abbott said in a release. “No state can match what Texas brings to this mission.”

“NASA’s Johnson Space Center, world-class universities, a premier commercial space industry, major military installations, and an unmatched aerospace workforce give Texas every asset the United States Space Academy requires,” the governor added.

Houston space companies take off with new tech, deals and contracts

space update

Space City has had a busy month.

Houston-based aerospace institutions Venus Aerospace, Axiom Space, and Aegis Aerospace have each recently announced advancements in their respective fields that include expansions and new contracts from U.S. and international government agencies.

Here’s the latest:

Venus launches new test stand

Earlier this month, Venus Aerospace added infrastructure to support the ongoing progress of its Rotating Detonation Rocket Engine (RDRE) with the opening of its new propulsion test stand at the Houston Spaceport.

The Texas Space Commission's Space Exploration and Aeronautics Research Fund is funding the test stand, which is part of a larger effort from the state to increase investments in the aerospace economy. The ribbon-cutting event on Sept. 10 welcomed officials from Venus Aerospace, the Texas Space Commission, the Houston Spaceport, Houston business and local community leaders.

With the new stand, Venus will be able to test at higher thrust and for longer durations, which will allow the company to better replicate real-life conditions.

"Building and testing propulsion systems at this pace requires the right infrastructure around the technology," Sassie Duggleby, CEO and co-founder of Venus Aerospace, said in a news release. "We're grateful to the Texas Space Commission and the State of Texas for investing alongside companies like Venus. Public investment like this helps companies move faster and keeps critical aerospace capability growing here in Texas."

Venus closed a $91 million Series B in July and expanded its leadership team.

Axiom partners in Europe

Axiom Space has signed a memorandum of understanding with the European Space Agency for “sustained European access to low-Earth orbit (LEO)” following the retirement of the International Space Station, according to a news release from the company.

Under the agreement, Axiom and the ESA agreed to explore future astronaut missions on the ISS and Axiom Station, research, transportation and spacesuit partnerships. The organizations will explore using the ESA’s European Cargo Return service and potentially a future European crew vehicle to support operations at Axiom Station, the company's forthcoming commercial space station. The partnership could also involve Axiom's AxEMU spacesuit for orbital and lunar applications, according to the release.

“With the upcoming de-orbitation of the ISS, it is our duty to anticipate and prepare future solutions to ensure our access to low-Earth orbit,” Daniel Neuenschwander, director of human and robotic exploration at ESA, said in the release. “The two documents signed today underline both our commitment to safeguard our ability to pursue in-orbit science and to keep offering flight opportunities to our European astronaut corps, as well as the growing interest of international partners for our ongoing project to develop an autonomous European cargo vehicle.”

The announcement comes as Axiom has made several international moves this year. The company shared plans to establish Axiom Space Switzerland this summer and launched Axiom Space Japan in July.

"The path to a sustainable human presence in space runs through international collaboration — reliable supply chains, shared innovation, and partners who bring real capability," Jonathan Cirtain, CEO and President of Axiom Space, said in the release. "Europe's contributions to microgravity science and deep space technology make ESA exactly that kind of partner. This MoU strengthens our work together, and we look forward to ESA and its member states joining us as customers for future astronaut missions."

Aegis expands DoW deal

Webster, Texas-based Aegis Aerospace announced that it has won a new task order to continue supporting the U.S. Space Force’s Space Test Program.

The contract starts in October and covers designing, building, testing and operating Department of War payloads or equipment on NASA, government, and commercial launch vehicles and platforms. The contract was issued by the USSF Space Systems Command, Space Test Program under NASA Johnson Space Center’s Research, Engineering, and Mission Integration Services 2 (REMIS 2).

Currently, the company is working on three payload facilities on the ISS and has plans for two more in development.

“Aegis Aerospace is grateful to continue our exceptional payload integration support to the USSF and the STP to meet their critical mission objectives,” President Matt Ondler added in the release. “This work is more important than ever to maintain U.S. superiority in space. This new contract will take us beyond the current life of the ISS and see us integrate and test payloads on commercial space stations, free-flyers, and cislunar missions.”
