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 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.

In a time when our health care heroes are serving on the front lines of the coronavirus, it's a great reminder of the work they all do round — from the research labs and academic institutions to the patient rooms. Jim Allison, a researcher in immunotherapy for MD Anderson Cancer Center recently took home the Nobel Prize for his work. He went on to be the subject of a documentary that premiered at SXSW last year, and that film will be coming to a TV near you.

Jim Allison: Breakthrough premieres on Independent Lens at 9 pm Monday, April 27, on PBS, PBS.org, and the PBS Video App. Read more.

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!"

Houston scientist wins Nobel Prize for breakthrough cancer treatment

Research Recognition

A University of Texas MD Anderson Cancer Center scientist has been lauded for his cancer research. Jim Allison, Ph.D., was announced as the recipient of the 2018 Nobel Prize in Physiology or Medicine on October 1.

Allison, who is the chair of Immunology and executive director of the Immunotherapy Platform, is the first MD Anderson scientist to receive the world's most coveted award for discoveries in the fields of life sciences and medicine. Allison won for his work in launching an effective new way to attack cancer by treating the immune system rather than the tumor, according to a release.

"I'm honored and humbled to receive this prestigious recognition," Allison says in a statement. "A driving motivation for scientists is simply to push the frontiers of knowledge. I didn't set out to study cancer, but to understand the biology of T cells, these incredible cells to travel our bodies and work to protect us."

Allison shares the award with Tasuku Honjo, M.D., Ph.D., of Kyoto University in Japan. When announcing the honor, the Nobel Assembly of Karolinska Institute in Stockholm noted in a statement that "stimulating the ability of our immune system to attack tumor cells, this year's Nobel Prize laureates have established an entirely new principle for cancer therapy."

The prize recognizes Allison's basic science discoveries on the biology of T cells, the adaptive immune system's soldiers, and his invention of immune checkpoint blockade to treat cancer. According to MD Anderson, Allison's crucial insight was to block a protein on T cells that acts as a brake on their activation, freeing the T cells to attack cancer. He developed an antibody to block the checkpoint protein CTLA-4 and demonstrated the success of the approach in experimental models.

Allison's work led to the development of the first immune checkpoint inhibitor drug which would become the first to extend the survival of patients with late-stage melanoma. Follow-up studies show 20 percent of those treated live for at least three years, with many living for 10 years and beyond, unprecedented results, according to the cancer center.

"Jim Allison's accomplishments on behalf of patients cannot be overstated," says MD Anderson president Peter WT Pisters, M.D., in a statement. "His research has led to life-saving treatments for people who otherwise would have little hope. The significance of immunotherapy as a form of cancer treatment will be felt for generations to come."

"I never dreamed my research would take the direction it has," Allison adds. "It's a great, emotional privilege to meet cancer patients who've been successfully treated with immune checkpoint blockade. They are living proof of the power of basic science, of following our urge to learn and to understand how things work."

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
