Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.

Houston cell therapy company launches second-phase clinical trial

fighting cancer

A Houston cell therapy company has dosed its first patient in a Phase 2 clinical trial. March Biosciences is testing the efficacy of MB-105, a CD5-targeted CAR-T cell therapy for patients with relapsed or refractory CD5-positive T-cell lymphoma.

Last year, InnovationMap reported that March Biosciences had closed its series A with a $28.4 million raise. Now, the company, co-founded by Sarah Hein, Max Mamonkin and Malcolm Brenner, is ready to enroll a total of 46 patients in its study of people with difficult-to-treat cancer.

The trial will be conducted at cancer centers around the United States, but the first dose took place locally, at The University of Texas MD Anderson Cancer Center. Dr. Swaminathan P. Iyer, a professor in the department of lymphoma/myeloma at MD Anderson, is leading the trial.

“This represents a significant milestone in advancing MB-105 as a potential treatment option for patients with T-cell lymphoma who currently face extremely limited therapeutic choices,” Hein, who serves as CEO, says. “CAR-T therapies have revolutionized the treatment of B-cell lymphomas and leukemias but have not successfully addressed the rarer T-cell lymphomas and leukemias. We are optimistic that this larger trial will further validate MB-105's potential to address the critical unmet needs of these patients and look forward to reporting our first clinical readouts.”

The Phase 1 trial showed promise for MB-105 in terms of both safety and efficacy. That means that potentially concerning side effects, including neurological events and cytokine release above grade 3, were not observed. Those results were published last year, noting lasting remissions.

In January 2025, MB-105 won an orphan drug designation from the FDA. That results in seven years of market exclusivity if the drug is approved, as well as development incentives along the way.

The trial is enrolling its single-arm, two-stage study on ClinicalTrials.gov. For patients with stubborn blood cancers, the drug is providing new hope.

Houston health tech startup revolutionizing spinal taps receives FDA clearance

tap in

Houston startup IntuiTap Medical has gained clearance from the U.S. Food and Drug Administration for its VerTouch medical device.

The company says VerTouch is designed to make spinal punctures more accurate and consistent. The handheld imaging tool helps health care providers perform spinal punctures at a patient’s bedside.

IntuiTap says it plans to roll out the device at U.S. hospitals within the next year. The company is mulling global partnerships to help launch VerTouch.

IntuiTap’s proprietary spinal-mapping technology enables VerTouch to generate a 2D image of lumbar spinal anatomy, helping health care providers visualize a patient’s spine and guide them toward more precise needle placement.

Each year, 12.7 million Americans undergo an epidural, spinal block, or lumbar puncture, says IntuiTap.

“Having spent more than two decades pioneering the use of ultrasound to improve emergency lumbar punctures, I know the challenge of these procedures and that difficult training and image interpretation prevent ultrasound from being a complete solution,” Dr. Michael Blaivas, co-founder past president of the Society of Ultrasound in Medical Education, says in a news release.

IntuiTap says the FDA clearance “validates the safety and effectiveness” of VerTouch. The device has undergone testing at several institutions in the U.S., including Houston’s Texas Medical Center and Chicago’s Northwestern Memorial Hospital.

Jessica Traver, co-founder and CEO of IntuiTap, says the FDA clearance “marks a crucial milestone in our team’s journey to making epidurals, spinals, and lumbar punctures more accurate and efficient.”

Investors in IntuiTap include:

  • Dr. Paul Klotman, president of the Baylor College of Medicine
  • Venture capitalist Tim Draper
  • William Hawkins III, retired CEO of medical device giant Medtronic
  • Dr. Vip Patel, Founder of the Global Robotics Institute
  • Dr. Mary Klotman, dean of the Duke University’s medical school
  • Carrie Colbert, founder of Houston-based Curate Capital, a female-focused VC firm

“Our investment in IntuiTap was just as much about our faith in the technology, our faith in Jessica as the founder, and our conviction that innovation was sorely needed in this area,” Colbert says.

“The fact that the company is receiving FDA clearance is a huge leap forward, and as a venture capital fund who focuses on female-founded companies that benefit women, it’s extremely rewarding to know this device will impact so many women’s lives.”

In 2021, IntuiTap announced it had closed a $5.5 million series A funding round led by Curate Capital and The Pink Ceiling, a woman-centered investment firm. The startup was founded in 2016.

Houston immuno-oncology company reaches next FDA milestone, heads to phase 2 trial

green light

A Houston immuno-oncology company has recently made major headway with the FDA, including both a fast track and an orphan drug designation. It will soon start a phase 2 trial of its promising cancer fighting innovation.

Diakonos Oncology was born in 2016, the brainchild of Baylor researchers already hard at work in the realm of dendritic cell vaccines. Drs. Will Decker, Matt Halpert, and Vanaja Konduri partnered with Dan Faust, a Houston businessman and pharmacist, to bring their treatment to the public, says COO Jay Hartenbach.

The name Diakonos means “deacon or servant in Greek,” he explains. “A lot of companies end up focusing on treating a specific disease or cancer and what you end up having is a significant amount of potential but with a lot of tradeoffs and downsides. And so our goal is we need to eliminate the cancer but we can't harm or dramatically malign the patient in doing so.”

How do they do that? Because the therapy catalyzes a natural immune response, it’s the patient’s own body that’s fighting the cancer. Hartenbach credits Decker with the idea of educating dendritic cells to attack cancer, in this case, glioblastoma multiforme (GBM), one of the most aggressive cancers with which doctors and patients are forced to tangle.

“Our bodies are already very good at responding very quickly and aggressively to what it perceives as virally infected cells. And so what Dr. Decker did was basically trick the immune system by infecting these dendritic cells with the cancer specific protein and mRNA,” details Hartenbach.

But GBM isn’t the only cancer on which Diakonos Oncology has its sights set. Other notably stubborn-to-treat cancers that they’re working on include pancreatic cancer and angiosarcoma. The scientists are focused on meeting unmet medical needs, but also realize that treating such cancers would allow for the fastest determination of whether or not the treatment was effective.

The fast track designation, originally received last fall, means that the drug approval time for DOC1021, Diakonos’ glioblastoma vaccine, will be only six months. But Hartenbach highlights an additional boon, the fact that the special designation also allows for more frequent communications with the FDA.

“That’s very helpful for us, right as we're contemplating how to design the upcoming trials. From a business standpoint, it also is incredibly helpful because it provides a third party validation of what we're doing and the results that we're seeing,” he says.

What they’re seeing includes the survival of 13 out of 16 patients from the initial October 2021 enrollment. The three patients who passed away received the lowest dose of DOC1021. Hartenbach says that the remaining patients are thriving, with no serious adverse effects. With a median survival rate of 15 to 21 months, it’s hard to understate the significance of these patients’ success.

Diakonos Oncology is headquartered in Houston, with a staff of 10 in Space City and an additional eight distributed employees. Hartenbach says that the company’s hometown has been instrumental in its success. He mentions that the robust innovation of the Texas Medical Center meant that as the company has grown, there has never been a motivation to leave Houston.

“You're having a lot of both investment and companies actually moving to Houston,” Hartenbach says. “So we’ve been fortunate to have started there. There are bigger traditional biotech hubs, San Diego, Boston, and San Francisco, but Houston really is now putting itself on the map and it's getting a lot of attention.”

One of the companies responsible for that improved reputation? Diakonos Oncology and its promising approach to aggressive cancers.

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.

Baylor, Rice win $500,000 to launch humanities-driven health AI center

ethical AI

Baylor College of Medicine and Rice University have been awarded a $500,000 grant from the National Endowment for the Humanities (NEH) to create the Center for Humanities-based Health AI Innovation (CHHAIN).

The new center and three-year initiative aims to create ethically responsible and trustworthy AI for health care that uses history and patient narratives to shape the technology, according to a release. It represents a collaboration between the Center for Medical Ethics and Health Policy at Baylor and the Medical Humanities Research Institute at Rice. Ultimately, the researchers aim to establish a national model for integrating the humanities into the design and implementation of health AI.

Vasiliki Rahimzadeh, assistant professor at Baylor in the Center for Medical Ethics and Health Policy, and Kirsten Ostherr, director of the Medical Humanities Research Institute at Rice, will serve as co-directors of the new center, which will be housed within the Center for Medical Ethics.

The team will also engage in strategic collaborations with Kirstin Matthews, Rice’s Baker Institute for Public Policy and its fellow in science and technology policy, as well as Dr. Quianta Moore, executive director of the Meadows Mental Health Policy Institute. An interdisciplinary team of medical humanities and bioethics scholars from Baylor, Rice, and partners in the Houston area will complete the group.

“CHHAIN represents a bold new model for integrating the humanities into health innovation,” Ostherr said in a news release. “It will create a collaborative space where humanities scholars, patients, developers and clinicians can come together to explore the human dimensions of health AI—trust, narrative and lived experience. These are essential perspectives that are too often missing from technology development, and CHHAIN is designed to change that."

CHHAIN’s work will revolve around three key points:

  • Defining trustworthy AI through patient voices
  • Translating humanities insights into clinical AI settings
  • Public engagement and policy translation

“For AI to truly improve health outcomes, it must be designed with patient trust and wellbeing at its core,” Rahimzadeh said in the news release. “CHHAIN will provide a dedicated space to explore critical bioethics questions, such as how we ensure AI respects patient autonomy, addresses the needs of underserved communities and integrates meaningfully into clinical care. Our goal is to translate these insights into real-world health settings where AI is already shaping patient experiences."

CHHAIN's research mission was also developed thanks to pilot funding from the Margaret M. and Albert B. Alkek Department of Medicine at Baylor and a grant from Rice's Provost's TMC Collaborator Fund.

Texas A&M, the University of North Texas and the University of Texas at El Paso were also home to some of the 97 projects that received a portion of the $34.79 million in fundning from the NEH. See the full list here.

Houston booms as No. 2 U.S. market for retail construction in 2025

Construction Zone

Get ready for a gigantic cartload of new shopping opportunities in Houston. A new report indicates the equivalent of 21 Walmart supercenters is under construction in the region.

The report, published by commercial real estate services provider Lee & Associates, says Houston has nearly 3.9 million square feet of retail space under construction, making it the second most active market for new retail space in the U.S.

To put that in perspective, given the average Walmart supercenter measures 182,000 square feet, the 3.9 million-square-foot total would work out to 21 new supercenters being built in the region.

Dallas-Fort Worth is by far the most active U.S. market for new retail space; DFW leads more than 60 U.S. retail markets with nearly 7.15 million square feet of space under construction. The amount of retail space going up in DFW represents 15 percent of all retail space under construction in the more than 60 U.S. markets tracked by Lee & Associates.

Houston and Austin aren’t too far behind Dallas-Fort Worth, though.

Third-ranked Austin area has more than 3.4 million square feet of retail space being built.

What’s behind the surge in retail construction across Texas? Population growth.

Data recently released by the U.S. Census Bureau shows Houston was the second-fastest-growing metro from 2023 to 2024. DFW was the country’s third-fastest-growing metro from 2023 to 2024, based on the number of new residents, and Austin landed at No. 13.

Intuitive Machines to acquire NASA-certified deep space navigation company

space deal

Houston-based space technology, infrastructure and services company Intuitive Machines has agreed to buy Tempe, Arizona-based aerospace company KinetX for an undisclosed amount.

The deal is expected to close by the end of this year, according to a release from the company.

KinetX specializes in deep space navigation, systems engineering, ground software and constellation mission design. It’s the only company certified by NASA for deep space navigation. KinetX’s navigation software has supported both of Intuitive Machines’ lunar missions.

Intuitive Machines says the acquisition marks its entry into the precision navigation and flight dynamics segment of deep space operations.

“We know our objective, becoming an indispensable infrastructure services layer for space exploration, and achieving it requires intelligent systems and exceptional talent,” Intuitive Machines CEO Steve Altemus said in the release. “Bringing KinetX in-house gives us both: flight-proven deep space navigation expertise and the proprietary software behind some of the most ambitious missions in the solar system.”

KinetX has supported deep space missions for more than 30 years, CEO Christopher Bryan said.

“Joining Intuitive Machines gives our team a broader operational canvas and shared commitment to precision, autonomy, and engineering excellence,” Bryan said in the release. “We’re excited to help shape the next generation of space infrastructure with a partner that understands the demands of real flight, and values the people and tools required to meet them.”

Intuitive Machines has been making headlines in recent weeks. The company announced July 30 that it had secured a $9.8 million Phase Two government contract for its orbital transfer vehicle. Also last month, the City of Houston agreed to add three acres of commercial space for Intuitive Machines at the Houston Spaceport at Ellington Airport. Read more here.
