Unique cell therapy developed in Houston doses inaugural patient

cancer-fighting innovation

Replay, a genome-writing company headquartered in San Diego, has announced that its first patient has been dosed with an engineered T-Cell Receptor Natural Killer (TCR-NK) cell therapy for relapsed or refractory multiple myeloma.

What does that have to do with Houston? Last year, Replay incorporated a first-in-class engineered TCR-NK cell therapy product company, Syena, using technology developed by Dr. Katy Rezvani at The University of Texas MD Anderson Cancer Center.

Rezvani, a professor of stem cell transplantation and cellular therapy, is the force behind MD Anderson’s Rezvani Lab, a group of 55 people, all focused on harnessing natural killer cells to combat cancer.

“Everybody thinks that the immune system is fighting viruses and infections, but I feel our immune system is capable of recognizing and killing abnormal cells or cells that are becoming cancerous and they're very powerful. This whole field of immunotherapy really refers to the power of the immune system,” Rezvani tells InnovationMap.

At Rezvani Lab, scientists train immune cells to fight cancer. While cancer drugs like chemotherapy are still the norm, immunotherapy has gained ground, led by Houston research, including the work of Nobel laureate Jim Allison. The harnessed cells are taught to attack cancerous cells, while ignoring healthy ones, says Rezvani. “We’re turning them into heat-seeking missiles,” she explains.

However, there must be a beacon to signal to those “missiles” that there is something to attack. Much of the field has used chimeric antigen receptors (CARs) to achieve that. But they have limitations.

“CARs can only recognize beacons that sit on the surface of the tumor cells,” Rezvani says. “So basically, it's like the tumor cell has to have a hat on it.”

She says that this usually means that the targets that send off a signal are relatively limited, mostly blood cancers. Using T cell receptors (TCRs) may be able to open up the field to look beyond the “hat.” In other words, TCRs can peer inside cells and see what differentiates a tumor cell from healthy cells. With Replay, Rezvani Lab has developed a first-in-class and first-in-human approach of engineering natural killer cells to express the TCR.

There are six different FDA-approved products that use CAR-T cells, but Rezvani says that her TCR-NK-based technology, though still in its early phases, shows great promise.

“We could use it to target many different types of antigens, many different types of cancers, especially solid tumors," she explains. "These cell therapies have a lot of potential — we call them living drugs… It's not like chemotherapy where you have to keep giving different multiple cycles, these cells are very long lived.”

Rezvani, who started her career in London, says that Houston has been instrumental in the success of her lab.

“There are so many opportunities because we have access to some of the most brilliant minds in research,” Rezvani says. “We have some of the best clinicians in the world. We have patients who come to us who are willing to participate in our clinical trials — really put their trust in us — and are committed and want to participate in these clinical studies.”

The role of funding also plays a part. As Rezvani admitted, bringing a new technology to the market is expensive. The philanthropists who help support trials can’t be forgotten among Houston’s finest.

Whether or not Syena produces the first TCR-NK product on the market, Rezvani is enthusiastic and hopeful for the future of her patients.

“The field of immunotherapy is really expanding, the field of cell therapies is expanding, and there is so much promise,” she says. “The promise of AI, big data, all the engineering tools that we have available, the promise of CRISPR — all of that is going to bring what we've learned from biology, from basic science, together to help us make the cell therapies that are going to be safe and and also very effective for our patients.”

Houston immunotherapy company achieves FDA designation for cancer-fighting vaccine

got the green light

The FDA has granted a Houston-based company a Fast Track designation.

Diakonos Oncology Corp. is a clinical-stage immuno-oncology company that has developed a unique dendritic cell vaccine, DOC1021. The vaccine targets glioblastoma multiforme (GBM), the most common and most lethal malignant brain tumor in adults. The aggressive tumors come with a life expectancy of about 15 months following diagnosis. About 7 percent of those diagnosed survive five years, while the 10-year outlook only sees a one-percent survival rate.

“The FDA’s decision acknowledges the potential of this new treatment approach for a very challenging disease,” Diakonos CEO Mike Wicks says in a press release. “Our protocol represents a first for cancer immunotherapy and could be viable for many types of cancers beyond GBM.”

FDA Fast Track designations are intended to expedite the haste with which drugs with early clinical promise are reviewed, likely taking them to market faster.

DOC1021 uses the body’s natural anti-viral immune response to fight GBM. The vaccine mimics viral infection with the patient’s cancer markers. Essentially, DOC1021 uses the body’s own natural ability to detect and eliminate infected cells.

The technology uses dendritic cells, white blood cells that are able to perceive threats, to its advantage. The unique cancer markers are loaded both internally and externally into the immune cells, just as they would simultaneously occur in a viral infection. The individualized treatment is administered through three precise injections that target deep cervical lymph node chains. By dosing this way, the immune responses are directed straight to the central nervous system.

The results have spoken for themselves: All of the patients who have tried the treatment have exceeded survival expectations. And just as importantly, DOC1021 appears to be extremely safe. No serious adverse effects have been reported.

“Because Phase I clinical trials are generally not statistically powered to demonstrate efficacy, detection of a statistically significant efficacy signal is very promising,” says William Decker, associate professor of immunology at Baylor College of Medicine and inventor of the DOC1021 technology.

The Phase 1 open-label trial of DOC1021 (NCT04552886) is currently taking place at both the University of Texas Health Science Center in Houston and at the MD Anderson Cancer Center at Cooper University Health Care in Camden, NJ. The trial is expected to complete this year.

Houston immunotherapy company to use $13.5M grant to further develop cancer treatments

future of pharma

Between Bangalore and Chennai in the Indian state of Andhra Pradesh, you’ll find the town of Tirupati. It’s home to seven peaks that host a Hindu temple complex devoted to a form of Vishnu, Venkateshvara. It is also the region from which Upendra Marathi originally hails. It’s where his father, and many other family members, attended medical school.

“My father’s first job was to take care of the pilgrims,” recalls Marathi.

It's only natural that his groundbreaking Houston company would be named 7 Hills Pharma.

“That sort of selflessness and giving back, I wanted to embody it in the name of the company,” Marathi says.

Now, 7 Hills Pharma is announcing that last month, it was awarded a $13.5 million grant from the Cancer Prevention and Research Institute of Texas (CPRIT). That’s on top of more than $13 million in NIH grants, making the company the second largest recipient of SBIR/STTR grants in Texas.

Launched in 2016, 7 Hills Pharma is working to develop drugs that can overcome the all-too-common problem of immunotherapy resistance. Thanks to the Nobel Prize-winning work of Jim Allison in the realm of immuno-oncology, the field was “very hot” at the time, says Marathi, particularly in Houston.

So what has 7 Hills developed? Oral small molecules that activate integrins — the receptors that allow cells to bind to one another — allowing for the cell-to-cell interactions that create a successful immune response to immune checkpoint inhibitors such as Yervoy. In other words, they have created capsules that increase the effectiveness of drugs that allow the body’s own immune response to fight cancers.

But that’s not all. Tests have shown that the same discovery, called alintegimod, can also augment the effectiveness of vaccines. The pill, which co-founder and co-inventor Peter Vanderslice calls “a beautiful way to amplify the vaccines,” can potentially be applied to anything from influenza to coronavirus.

Their greatest challenge, says Vanderslice, is the very fact that the technology is so novel.

“Most large pharmas are very risk averse,” he explains. “They only want to do ‘me-too’ kinds of drugs.”

7 Hills Pharma is the third company Marathi, both a PhD and an MBA, has helped to found based on technology he co-invented. Vanderslice is director of the molecular cardiology research laboratories at The Texas Heart Institute.

“It’s very much a homegrown company,” Marathi says.

And a small one, at least for now. Working out of JLabs@TMC, the full-time team is currently just Marathi and Siddhartha De, the senior director of development. Marathi convinced De to transplant himself and his family from India for the purpose of assisting 7 Hills with preparing its drugs for clinical readiness.

The CPRIT funds will allow 7 Hills Pharma to hire several long-time team members full-time and with benefits.

“The bringing of talent and bringing of technology to TMC and what was born at Texas Heart Institute is rather remarkable,” says Rob Bent, the company’s director of operations.

The next step for 7 Hills Pharma is a Phase Ib/IIa clinical trial in patients with treatment-resistant solid tumors. And the team just finalized the deck that will help raise another $10 million to $250 million in the company’s series A. And hopefully sooner rather than later, a new set of medical pilgrims will be thanking 7 Hill Pharma for its care.

University of Houston researchers snag $1.8M to develop cancer-fighting virus

immunotherapy innovation

Viruses attack human cells, and that's usually a bad thing — some Houston researchers have received fresh funding to develop and use the evil powers of viruses for good.

The developing cancer treatment is called oncolytic virotherapy and has risen in popularity among immunotherapy research. The viruses can kill cancer cells while being ineffective to surrounding cells and tissue. Basically, the virus targets the bad guys by "activating an antitumor immune response made of immune cells such as natural killer (NK) cells," according to a news release from the University of Houston.

However exciting this rising OV treatment seems, the early stage development is far from perfect. Shaun Zhang, director of the Center for Nuclear Receptors and Cell Signaling at the University of Houston, is hoping his work will help improve OV treatment and make it more effective.

“We have developed a novel strategy that not only can prevent NK cells from clearing the administered oncolytic virus, but also goes one step further by guiding them to attack tumor cells. We took an entirely different approach to create this oncolytic virotherapy by deleting a region of the gene which has been shown to activate the signaling pathway that enables the virus to replicate in normal cells,” Zhang says in the release.

Zhang, who is also a M.D. Anderson professor in the Department of Biology & Biochemistry, has received a $1.8 million grant from the National Institutes of Health to continue his work.

Zhang and his team are specifically creating a new OV — called FusOn-H2 and based on the Herpes simplex 2 virus.

“Our recent studies showed that arming FusOn-H2 with a chimeric NK engager (C-NK-E) that can engage the infiltrated natural killer cells with tumor cells could significantly enhance the effectiveness of this virotherapy,” he says. “Most importantly, we observed that tumor destruction by the joint effect of the direct oncolysis and the engaged NK cells led to a measurable elicitation of neoantigen-specific antitumor immunity.”

Documentary featuring Houston Nobel Prize winner to air on PBS

to-watch list

Not all heroes wear capes. In fact, our current coronavirus heroes are donning face masks as they save lives. One local health care hero has a different disease as his enemy, and you'll soon be able to stream his story.

Dr. James "Jim" Allison won the 2018 Nobel Prize in Physiology or Medicine for his work in battling cancer by treating the immune system — rather than the tumor. Allison, who is the chair of Immunology and executive director of the Immunotherapy Platform at MD Anderson Cancer Center, has quietly and often, singularly, waged war with cancer utilizing this unique approach.

The soft-spoken trailblazer is the subject of an award-winning documentary, Jim Allison: Breakthrough, which will air on PBS and its streaming channels on Monday, April 27 at 9 pm (check local listings for channel information). Lauded as "the most cheering film of the year" by the Washington Post, the film follows Allison's personal journey to defeat cancer, inspired and driven by the disease killed his mother.

Breakthrough is narrated by Woody Harrelson and features music by Willie Nelson, adding a distinct hint of Texana. (The film was a star at 2019's South by Southwest film festival.) The documentary charts Alice, Texas native as he enrolls at the University of Texas, Austin and ultimately, cultivates an interest in T cells and the immune system — and begins to frequent Austin's legendary music scene. Fascinated by the immune system's power to protect the body from disease, Allison's research soon focuses on how it can be used to treat cancer.

Viewers will find Allison charming, humble, and entertaining: the venerable doctor is also an accomplished blues harmonica player. Director Bill Haney weaves Allison's personal story with the medical case of Sharon Belvin, a patient diagnosed with melanoma in 2004 who soon enrolled in Allison's clinical trials. Belvin has since been entirely cancer-free, according to press materials.

"We are facing a global health challenge that knows no boundaries or race or religion, and we are all relying on gifted and passionate scientists and healthcare workers to contain and ultimately beat this thing," said Haney, in a statement. "Jim Allison and the unrelenting scientists like him are my heroes – and I'll bet they become yours!"

Generation Park lands new facility to scale xeno-organ production

Organ innovation

Maryland-based United Therapeutics Corp. has opened a new 77,448-square-foot facility to manufacture xeno-organs in Northeast Houston’s growing biotech hub, Generation Park.

The new Houston location is United Therapeutics’ third Designated Pathogen-Free (DPF) site, named for transplant pioneers Dr. Bartley P. Griffith and Dr. Robert A. Montgomery. The company says the new facility will enable it to scale commercial production of its xeno-organs once they receive regulatory approval.

An existing DPF facility in Virginia is supporting clinical trials for the xeno-organs, and a third site in Minnesota will also focus on commercialization with the Houston site, according to the company.

Xeno-organs are organs taken from a non-human animal source and transplanted, implanted or infused into a human recipient.

Currently, United Therapeutics is advancing clinical trials to support a Biologics License Application with the U.S. Food and Drug Administration for its investigational-stage xenotransplantation, UKidney, UThymoKidney and UHeart products. The products all involve working with the genes from humans and pigs.

In 2025, Chron.com reported the company was working to construct an estimated $96 million facility to breed genetically engineered animals. Head of investor relations at United Therapeutics Dewey Steadman told the Houston Business Journal in 2025 that the pigs’ DNA will be edited. In November 2024, a 53-year-old woman in Alabama received a transplanted kidney from UKidney that had 10 gene edits. She had the transplant removed in April 2025, after her body rejected it.

The Dr. Bartley P. Griffith and Dr. Robert A. Montgomery Xenograft Production Facility requires a “strictly controlled, biosecure barrier environment, including air filtration, filtered water, filtered feed supplies, and state-of-the-art decontamination entryways,” according to the company. Being pathogen-free means it includes calibrated air and water conduits to support the transplantability of xenograft products and to prevent contamination. For energy considerations, the building also features solar arrays.

“With our third xenograft production facility now open and clinical trials underway, United Therapeutics is moving closer to its goal of providing transplantable organs to the people who need them,” Martine Rothblatt, chairperson and CEO of United Therapeutics, said in a news release. “It is fitting that this facility is named for Dr. Griffith and Dr. Montgomery, whose first-in-human surgeries turned xenotransplantation from a theoretical possibility into a clinical reality.”

The facility, which wrapped construction in August, is located at 11848 Common Dock Dr. in Generation Park, which will house manufacturing sites for pharmaceutical heavyweights Bristol Myers Squibb and Eli Lilly. Last fall, Eli Lilly tapped Generation Park for its $6.5 billion manufacturing plant, and Bristol Myers Squibb made a $2.3 billion investment in August to bring its state-of-the-art site to the master-planned commercial district.

Elon Musk's SpaceX reports profit as AI and satellite businesses booms

Booming Business

SpaceX reported a bigger quarterly profit than expected on Tuesday, October 20, as its satellite communications and artificial intelligence businesses boomed.

The company, run by Elon Musk, posted a profit for the three months through September 2026 of $4.4 billion, or 35 cents per share, reversing a year-ago loss and easily topping Wall Street's expectations. Revenue soared to $14.6 billion, up 161%.

On a conference call with analysts, Musk suggested a merger with his electric car company Tesla might be in the works, something that has been rumored for months. He said both companies formed “special committees” of independent directors to discuss the issue, though he played down the chances of an imminent deal.

“Some people out there assume that a SpaceX and Tesla merger is a certainty,” he said. “I think that would be overstating it.”

The AI business became SpaceX's largest by revenue in the third quarter, although the Starlink satellite service remains the biggest profit generator.

“They beat across all metrics and the Starlink business looks to be accelerating,” said Dan Ives, an analyst at Yorkville Ives. “This is just what (Wall) Street wanted.”

The stock rose 7.5% in after-hours trading.

Musk also told analysts that for next month's launch of its Starship rocket, SpaceX will attempt to grab both the booster and ship with mechanical arms upon return to base, a key step toward demonstrating it can reuse the massive spacecraft.

“The only way that we can extend consciousness beyond Earth on a sustained basis is with a fully reusable orbital launch vehicle,” Musk said, calling the attempt, if successful, “a massive technology milestone.”

SpaceX hopes to get Starship on a regular launch pattern in preparation for NASA's upcoming lunar missions.

The company already has huge contracts with the federal government, and House Democrats have called for investigations into those contracts and Musk’s work with the Department of Government Efficiency. Musk has spent $276 million since July in support of Republican candidates.

In a filing for its initial public offering in June, SpaceX warned that a change in control of Congress could have a “material and adverse impact on our growth and competitive position.”

Musk recently drew criticism from politicians in Washington after speeds for a military version of SpaceX's satellite communications service were slowed for Ukraine following President Donald Trump's deal to get more diesel oil from Russia amid a push to end the war. The Wall Street Journal reported Tuesday that it was Musk who ordered the slowdown, impeding Ukraine’s use of drones along the front. SpaceX did not immediately respond to an Associated Press request for comment on the Journal story.

Both Trump and Musk have denied responsibility for the slowdown.

As midterm elections near, Musk on Monday promised to give one share of SpaceX to “every kid in America” next year, though he provided no details on how the distribution would be carried out. With communities nationwide protesting the construction of large data centers and concerns about AI safety, AI companies are trying to build goodwill. Anthropic pledged to commit 5% of its shares to a new “public benefit” fund.

SpaceX shares have been under pressure over concerns that the company was spending too much on major projects to compete with rivals such as Anthropic. The company said capital expenditures totaled $19.6 billion last quarter, nearly triple the figure from a year earlier, and it forecast spending would grow to $35 billion to $40 billion in the current quarter.

Shares of SpaceX closed Tuesday at $147.79, down from a peak near $201 after its IPO, which made Musk the world’s first trillionaire at the time. But the share prices for SpaceX and Tesla have since dropped, reducing his net worth to $925 billion, according to Forbes magazine.

Tesla reports third-quarter financial results Wednesday. Last week, Tesla unveiled a new Roadster sports car that in some versions may include thrusters allowing it to briefly fly using SpaceX technology — though experts say anything usable for drivers is a long shot.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.
