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!"

AI-powered Houston startup helps restaurants boost customer loyalty

order up

It’s no secret that restaurant trends move fast and margins run thin. And with the proliferation of platforms like Uber Eats, DoorDash and Easy Cater, customer loyalty is fleeting.

The solution?

How about an AI-powered restaurant technology platform that helps restaurant brands cut back on third-party platforms in favor of driving direct discovery, conversion and loyalty?

Enter Saivory. Founded in 2025 by Stephen Klein, a software investor, and Fajita Pete’s restaurateur Hugh Guill, the Houston-based startup aims to help eateries better understand and activate guest behavior across digital channels as AI increasingly reshapes how consumers discover and engage with brands.

In less than a year, Saivory has partnered with Shipley Do-Nuts and Fajita Pete’s to bring AI-powered ordering to life.

“With Saivory, we were able to answer the question of, ‘what if the ordering process could be reduced to a single step, where customers simply tell us what they want and AI takes care of the rest?’” Klein tells InnovationMap.

The Houston-based startup made such an immediate impact that it was selected as a semi-finalist during Start-Up Alley at MURTEC, the restaurant industry’s leading technology conference, which took place last month in Las Vegas.

“Houston is a great hub for technology innovation, and we were proud to represent the city at MURTEC this year,” says Klein. “We didn’t win, but we were able to talk about some of the work that we have existing in the market for clients right now and a little bit about what we’re working on in the future.”

In the current restaurant technology ecosystem, the third-party aggregators own the customer attention that brings volume to restaurants, while also taking big commissions and having control over the end relationships with the customer.

That can often make it difficult for restaurants to grow loyalty and repeat business from customers. Saivory aims to level the playing field for restaurants, helping them stay more connected to their customers.

Take Saivory’s recent application with Shipley’s Do-Nuts, for example.

Saivory powered the donut giant’s AI-ordering and launched Shipley's website and mobile app to support its over 300 locations in Texas alone.

Shipley’s new AI-powered assistant helps users create personalized order recommendations based on individual or group preferences. And unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size. It can also be used for large catering orders.

“They're seeing more traffic to the site and they're seeing when customers use our AI-enabled flows,” Klein says. “And they're seeing higher basket sizes, bigger tickets, by about 25 percent.”

Klein says Saivory’s technology helps strengthen first-party digital relationships, reduce friction and cart abandonment, improve average order value, and delivers personalized, efficient experiences.

“It’s a win-win: the customer gets the right order quickly, while the restaurant gets a bigger margin,” he adds.

Additionally, the technology makes it easier for restaurants to share rewards, loyalty and discounts, ultimately growing more direct traffic and making restaurants less reliant on third-party delivery apps.

Next up for Saivory is adding new components to its platform to enhance the relationship between restaurant and customer, as well as technology around making it easier for restaurants to get found on Google.

“A lot of people are still searching for the best donuts near me,” Klein says. “Or what’s the best Mexican food near me? Customers will increasingly move to AI, where they’re going to ask where they should eat dinner and expect it to just order them dinner. They will eventually expect the technology to know how to do that. So that’s what we’re driving at.”

Houston leads U.S. in population growth for 2025, Census says

Boomtown

Imagine that the Houston metro area swallowed a city the size of Pearland in just one year. That’s essentially what happened from 2024 to 2025, with the Houston metro ranking first in the U.S. for population growth based on the number of people.

New estimates from the U.S. Census Bureau show the 10-county Houston metro added 126,720 residents from July 1, 2024, to July 1, 2025. That’s just shy of Pearland’s roughly 133,000-resident tally.

To calculate population, the Census Bureau counts births, deaths, new residents, and moved-away residents.

Region’s population approaches 8 million

On July 1, 2025, the Houston metro’s population hovered slightly above 7.9 million, up 1.6 percent from the same time in 2024. In the very near future, the region’s population should break the eight million mark.

This follows massive growth in the past 20 years. From 2005 to 2025, the region’s population soared by 39 percent. By comparison, the growth rate from 2021 to 2025 sat at nine percent.

A forecast from the Texas Demographics Center indicates that under a middle-of-the-road scenario, the Houston metro’s population will reach nearly 8.5 million in mid-2030 and more than 9.5 million in mid-2040.

Dan Potter, director of Rice University’s Houston Population Research Center, attributes much of the region’s population surge to people moving to the area from outside the U.S. In Harris County, this means a combination of military personnel returning home, people living or working overseas coming back to the U.S., and immigrants relocating to the U.S., he tells CultureMap.

But Harris County fell short from 2024 to 2025 when it comes to people moving here from elsewhere in the U.S., according to Potter. Counties surrounding Harris County benefited from that trend, drawing new residents who preferred to settle in the suburbs.

“The incredible pull and attraction of the Houston area is its economy, its people, and its affordability, and the significant growth that was observed in 2024 and again in 2025 speaks to the magnetism of the region,” Potter says. “That pull to Houston is too strong to be turned off overnight.”

Cooling economy and immigration shifts slow down growth

Whether looking at urban or suburban places, population growth in the Houston area slowed in 2025 and appears to be slowing even more this year, Potter says.

“A cooling economy and changes to immigration policy are a one-two combination that could knock out the region’s population growth,” says Potter, citing the region’s addition of a less-than-expected 14,800 jobs in 2025 as an example.

Weaker population growth may not be felt evenly across the metro area, according to Potter.

A continuing influx of people from Houston to outlying counties such as Brazoria, Fort Bend, Liberty, Montgomery, and Waller could curb growth in Harris County, Potter said. Why? If the number of people arriving from other other countries flattens or even drops, then there could be “doughnut-style population growth for the next few years, where Harris County and Houston see declines while the suburban counties see an increase.”

Harris County represents 40 percent of region’s population lift

Houston-anchored Harris County accounted for almost 40 percent of the region’s population spike from 2024 to 2025. In one year, Harris County grew by 48,695 residents, or 1 percent, pushing its population past five million. That increase put Harris County in first place for numeric growth (rather than percentage growth) among all U.S. counties.

From 2020 to 2025, Harris County’s growth rate was 6.6 percent. It remains the country’s third largest county based on population, behind Southern California’s Los Angeles County and Illinois’ Chicago-anchored Cook County.

Harris County is on track to surpass Cook County in size in the near future. As of July 1, 2025, a nearly 150,000-resident gap separated population-losing Cook County and fast-growing Harris County.

The Texas Demographics Center predicts Harris County’s population will be 5.37 million in mid-2030 and just short of six million in mid-2040.

Suburban counties see significant population gains

Harris County isn’t the only county in the area that experienced a growth spurt from 2024 to 2025:

  • Waller County’s population climbed 5.69 percent, winding up at 69,858. Its growth rate ranked second among U.S. counties.
  • Liberty County’s population rose 4.4 percent to 121,364, putting its growth rate in eighth place among U.S. counties.
  • Montgomery County gained 30,011 residents, with its population landing at 781,194. That placed it at No. 4 among U.S. counties for numeric growth.
  • Fort Bend County picked up 24,163 residents, arriving at a total of 975,191 and positioning it at No. 8 among U.S. counties for numeric growth. Fort Bend County, the region’s second largest county based on population, is projected to break the one million-resident mark by July 2030, according to the Texas Demographics Center.

“Lower mortgage rates from 2009 to 2022 and the rise of remote work have made suburban housing more attractive, especially for families seeking affordability,” Pramod Sambidi, the Houston-Galveston Area Council’s assistant director of data analytics and research, said last year. “Additionally, suburban areas are seeing more multifamily developments than before the pandemic.”

5 Houston-area companies named among world's most innovative for 2026

In The Spotlight

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned praise on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.
