Several Houston institutions scored funding from the Cancer Prevention and Research Institute of Texas. Photo via Getty Images

German biotech co. to relocate to Houston thanks to $4.75M CPRIT grant

money moves

Armed with a $4.75 million grant from the Cancer Prevention and Research Institute of Texas, a German biotech company will relocate to Houston to work on developing a cancer medicine that fights solid tumors.

Eisbach Bio is conducting a clinical trial of its EIS-12656 therapy at Houston’s MD Anderson Cancer Center. In September, the company announced its first patient had undergone EIS-12656 treatment. EIS-12656 works by suppressing cancer-related genome reorganization generated by DNA.

The funding from the cancer institute will support the second phase of the EIS-12656 trial, focusing on homologous recombination deficiency (HRD) tumors.

“HRD occurs when a cell loses its ability to repair double-strand DNA breaks, leading to genomic alterations and instability that can contribute to cancerous tumor growth,” says the institute.

HRD is a biomarker found in most advanced stages of ovarian cancer, according to Medical News Today. DNA constantly undergoes damage and repairs. One of the repair routes is the

homologous recombination repair (HRR) system.

Genetic mutations, specifically those in the BCRA1 and BCRA1 genes, cause an estimated 10 percent of cases of ovarian cancer, says Medical News Today.

The Cancer Prevention and Research Institute of Texas (CPRIT) says the Eisbach Bio funding will bolster the company’s “transformative approach to HRD tumor therapy, positioning Texas as a hub for innovative cancer treatments while expanding clinical options for HRD patients.”

The cancer institute also handed out grants to recruit several researchers to Houston:

$2 million to recruit Norihiro Goto from the Massachusetts Institute of Technology to MD Anderson.
$2 million to recruit Xufeng Chen from New York University to MD Anderson.
$2 million to recruit Xiangdong Lv from MD Anderson to the University of Texas Health Science Center at Houston.

In addition, the institute awarded:

$9,513,569 to Houston-based Marker Therapeutics for a first-phase study to develop T cell-based immunotherapy for treatment of metastatic pancreatic cancer.
$2,499,990 to Lewis Foxhall of MD Anderson for a colorectal cancer screening program.
$1,499,997 to Abigail Zamorano of the University of Texas Health Science Center at Houston for a cervical cancer screening program.
$1,497,342 to Jennifer Minnix of MD Anderson for a lung cancer screening program in Northeast Texas.
$449,929 to Roger Zoorob of the Baylor College of Medicine for early prevention of lung cancer.

On November 20, the Cancer Prevention and Research Institute granted funding of $89 million to an array of people and organizations involved in cancer prevention and research.

Rice University innovators claim prizes across health care, energy research

big wins

Undergraduate students from Rice University were awarded the top prize in a health innovation challenge.

Design by Biomedical Undergraduate Teams (DEBUT) Challenge, which is organized by the National Institutes of Health (NIH) and the non-profit organization VentureWell, selected medical device team UroFlo as its winner, claiming the $20,000 prize. The technology, a continuous bladder irrigation system, was recognized for its potential to revolutionize post-operative care and improve patient outcomes.

The winning team from Rice consists of 2024 bioengineering graduates Anushka Agrawal, Sahana Prasanna, Robert Heeter, Archit Chabbi, Kevin Li, and Richard Chan. The UroFlo system provides care to patients after surgery and reduces the burden on health care professionals by implementing state-of-the-art sensors and machine learning algorithms with a touchscreen user interface. This helps with data collection, processing and visualization. UroFlo promises to enhance the management of urinary tract infections (UTIs) and help prevent blood clots.

“We have learned so much from this process and we are really proud of what we have accomplished,” says Chabbi in a news release. “It’s truly rewarding to know that our work can impact patients’ experience and help improve quality of care. Over the many hours we spent working in the Oshman Engineering Design Kitchen (OEDK) at Rice, we’ve not only developed an amazing set of skills, but have also forged really strong connections with one-another and the nearby medical community at the Texas Medical Center.”

The award will be presented on Oct. 25 in Baltimore during the annual Biomedical Engineering Society (BMES) conference.

UroFlo was also with first place in the Johns Hopkins Healthcare Design Competition in the Post-Surgical Infection Management category; first place in the American Society for Artificial Internal Organs Student Design Competition; “Best Medical Device Technology Award” in the 2024 Huff Engineering Design Showcase and competition held by the OEDK; “Outstanding Bioengineering Design Project,” Rice Department of Bioengineering; “Best Presentation” in the Texas Children’s Hospital Surgical Research Day; finalist and “Best Engineering Project” in Rice’s 2024 Shapiro Research Showcases; and semi-finalist in the H. Albert Napier Rice Launch Challenge. UroFlo will continue after Rice, as the project will be developed further.

“We are all very passionate about biomedical engineering, and dedicated and committed to making a difference” Chan said in a news release. “We actually decided to continue to develop UroFlo after our graduation from Rice a few months ago with the hope of improving our innovative solution for urological care.”

In other news, Rice University’s Naomi Halas won $7.5 million over five years from the United States Department of Defense (DOD) Air Force Office of Scientific Research (AFOSR) with her project proposal Multidisciplinary University Research Initiative (MURI) for her project titled “Combining Nonequilibrium Chemistries with Atomic Precision,” which competed in the category “plasmon-controlled single-atom catalysis.”

“Combining Nonequilibrium Chemistries with Atomic Precision” addressed the need for more energy-efficient and less protocol-intensive chemical processes that involve using light to drive chemical reactions and single-atom “reactors” to catalyze chemical reactions that are nearly 100 percent specific in terms of reaction products.

Plasmons work when they make metal nanoparticles act like antennas, and certain designed reactor sites on their surfaces can then carry out chemical reactions at a fraction of the “energy expenditure of conventional industrial catalysts” according to a news release.

Rice University and Baylor College of Medicine have also received $2.8 million in funding from the National Heart, Lung, and Blood Institute (NHLBI) for their research on reducing inflammation and lung damage in acute respiratory distress syndrome (ARDS) patients.

“Cell Based Immunomodulation to Suppress Lung Inflammation and Promote Repair,” will be co-led byRice’s Omid Veiseh, a professor of bioengineering and faculty director of the Rice Biotech Launch Pad, and professor of surgery at Baylor Ravi Kiran Ghanta. They will develop a new translational cell therapy platform “ to allow a better local administration of cytokines to the lungs in order to suppress inflammation and potentially prevent lung damage in ARDS patients” according to a news release.

Houston space co. secures $4.8B NASA contract to provide communications, navigation services

near space exploration

Houston-based space exploration, infrastructure, and services company Intuitive Machines has snagged a deal with NASA that could be worth more than $4 billion.

Under the contract, Intuitive Machines (Nasdaq: LUNR, LUNRW) will supply communication and navigation services for missions in the “near space” region, which extends from the earth’s surface to beyond the moon.

The five-year deal includes an option to add five years to the contract. In total, the contract could be worth $4.82 billion. The initial round of NASA funding runs from October 2024 through September 2029.

“This contract marks an inflection point in Intuitive Machines’ leadership in space communications and navigation,” Steve Altemus, CEO of Intuitive Machines, says in a news release.

Under the deal, the company will deploy lunar relay satellites and provide communication and navigation services that play a role in NASA’s Artemis campaign to establish a long-term presence on the moon.

A highlight of the contract is the debut of Intuitive Machines’ lunar satellite constellation, a service that the company “believes is a strategic element in its vision to commercialize lunar activities.” The constellation will deliver data and transmission services and enable autonomous operations.

Earlier this month, Intuitive Machines secured its fourth contract with NASA’s Commercial Lunar Payload Services, or CLPS, program. The $116.9 million agreement will task Intuitive Machines with delivering six science and technology payloads, which will include one European Space Agency-led drill suite to the Moon’s South Pole.

Additionally in August, Intuitive Machines signed a deal with Houston-based launch services company SEOPS to offer lunar rideshare services. Under the deal, Intuitive Machines will enable SEOPS to deliver customers' payloads to the surface of the moon, as well as to Lagrange points and geostationary transfer orbits.

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
