A Houston biotech company based off research out of UTHealth Houston has raised seed funding to continue developing its cancer-fighting therapeutic.

CrossBridge Bio, formed during the TMC Innovation’s Accelerator for Cancer Therapeutics program, closed a $10 million seed round led by TMC Venture Fund and Crescent Enterprises' VC arm, CE-Ventures. The round also included participation from Portal Innovations, Alexandria Venture Investments, Linden Lake Labs, and several pre-seed investors.

“We are thrilled to have the support of such experienced investors who share our vision of bringing transformative cancer therapies to patients in need,” Michael Torres, CEO of CrossBridge Bio, says in a news release. Torres served as an entrepreneur in residence of ACT.

The company is working on the next-generation of antibody-drug conjugates (ADC) therapeutics that process dual payloads as targeted treatments for a set of challenging cancers. The innovative treatment is based on research from UTHealth experts Dr. Kyoji Tsuchikama and Dr. Zhiqiang An.

“Our dual-payload ADC technology is designed to deliver synergistic therapeutic effects using highly stable linkers that ensure payload release only within the targeted cancer cells, thereby maximizing their therapeutic effectiveness while minimizing the liabilities associated with uptake in unintended tissues, as seen with many of today’s cancer treatments," Torres continues.

He explains that the funding will toward advancing CrossBridge's first development candidate, CBB-120, into preclinical non-GLP toxicology studies in addition to derisking the company’s proprietary linker technology with dual-payload applications, per the release.

As a result of the raise, William McKeon, president and CEO of the Texas Medical Center, and Damir Illich, manager of life sciences of CE-Ventures, will join CrossBridge Bio’s board of directors.

“We are proud to back CrossBridge Bio in their mission to develop the next generation of cancer therapies,” McKeon says in the release. “Their dual-payload ADCs are designed to deliver targeted drug release within cancer cells with greater stability, precision, and control. These breakthrough advancements have the potential to change patients’ lives worldwide and we look forward to helping drive their development.”

Chicago life science innovation firm names Houston leader

who's who

After announcing its expansion into Houston last summer and opening its office in a new Texas Medical Center building, Portal Innovations has named its Houston leader.

Portal Innovations announced that Monique Knighten as an executive director in Houston in a LinkedIn post this week. She has over 15 years of experience in supporting research scientists and clinicians working to develop therapeutics in labs and clinics. According to her LinkedIn, she's served in the position since November.

Prior to her new role at Portal, Knighten worked as a manager level at Sartorius Stedim in Houston for five years. Before that role, she served as a technical sales consultant in Texas at Miltenyi Biotec, primarily in the immuno-oncology therapeutic market in the TMC.

Portal first announced its expansion into Houston in June of last year.

“Houston is one of the fastest-growing cities in the U.S., and home to one of the world’s leading cancer research institutions, The University of Texas MD Anderson Cancer Center,” Portal’s Founder and CEO John Flavin said at the time. “It’s critical for us to open in Texas and leverage nearby pipelines from Rice University, UTHealth Houston, Texas A&M, University of Houston, Baylor College of Medicine, and others across Houston’s innovative life sciences ecosystem. We’re thrilled to work with TMC to help grow tomorrow’s biotech and medtech leaders.”

Portal's local office is in the Helix Park complex's Collaborative Building, which opened in October. Helix Park is a 37-acre mixed-use campus currently under construction. The institutional agnostic, 250,000-square-foot building will anchor Helix Park and house research initiatives from the four founding partners: Texas Medical Center, The University of Texas MD Anderson Cancer Center, Texas A&M University Health Science Center, and The University of Texas Health Science Center at Houston.

For nearly a decade, the Texas Medical Center and its partners have been working on the plans for Helix Park, a 37-acre campus expansion of TMC. As of this week, the first building has opened its doors to the public.

The TMC3 Collaborative Building officially opened today to a crowd of media, public officials, and health care executives. The institutional agnostic, 250,000-square-foot building will anchor Helix Park and house research initiatives from the four founding partners: Texas Medical Center, The University of Texas MD Anderson Cancer Center, Texas A&M University Health Science Center, and The University of Texas Health Science Center at Houston.

“Today, we lay the cornerstone of a new campus fully dedicated to streamlining the commercialization of life-changing innovations in medicine and technologies,” William McKeon, president and CEO of TMC, says at the event. “We are incredibly excited to both welcome our founding institutions and industry partners to the Collaborative Building and to invite the community to experience the Helix Park campus and its beautiful parks with a series of special events in the months ahead."

Established to be a place for academic institution collaboration, the building — designed by Boston-based Elkus Manfredi Architects — will have wet laboratories, office space, and event facilities. Two venture groups — Portal Innovations and the TMC Venture Fund — will also move into the building.

Each institution will bring in select programs and initiatives. MD Anderson will house two institutions within the new building, including the James P. Allison Institute focused on immunotherapy and the Institute for Data Science in Oncology.

"The future of life sciences in Houston is brighter than ever before as we come together to officially open the TMC3 Collaborative Building,” Dr. Peter WT Pisters, president of MD Anderson, says. “Our clinicians and scientists work daily to advance innovations in cancer research and care – all of which will be amplified in this new environment within Helix Park that further cultivates collaboration, connectivity, and creativity.”

UTHealth will move its Texas Therapeutics Institute into the facility.

“With a shared commitment to improving the health and well-being of individuals and communities, we are bringing together academics and industry to accelerate discovery and medical breakthroughs,” Dr. Giuseppe N. Colasurdo, president and Alkek-Williams Distinguished Chair at UTHealth Houston, says. “Through the Texas Therapeutics Institute — already a signature collaborative enterprise at UTHealth Houston — our world-renowned leaders in therapeutic antibody development will have the opportunity to work closely with other leading researchers in the Texas Medical Center, greatly enhancing our collective ability to translate discoveries and ideas into effective treatments.”

Texas A&M, which has worked with Houston Methodist to develop its engineering medical program, will operate its Texas A&M Health’s Institute of Biosciences and Technology in the new space.

“As we open this state-of-the-art facility, we’re opening the door to a new era of collaboration. This building signifies the dismantling of silos to deliver game-changing therapies for the toughest diseases impacting Texans and citizens worldwide,” said John Sharp, Chancellor of The Texas A&M University System. “Texas A&M Health’s Institute of Biosciences and Technology has long been a trailblazer in drug discovery, and now, in the heart of this resource-rich ecosystem of the Texas Medical Center, we’re taking it up a notch. By positioning our scientists near their peers and esteemed clinicians, we’re igniting a spark that will fuel innovation and forge dynamic research programs.”

The next aspect of Helix Park to deliver will be the Dynamic One, a 700,000-square-foot industry research facility. Several other buildings, including a hotel, residential tower, and mixed-use building, are expected to deliver over the next few years. The "spine" of the project is six linked green spaces, designed by landscape architect Mikyoung Kim, that form an 18.7-acre campus, which is shaped like a DNA helix, hence the project's name.

At the opening event, leaders discussed the annual impact of over $5.4 billion expected after the campus is completed, and the 23,000 permanent new jobs and 19,000 construction jobs anticipated from Helix Park.

"Texas truly is the home of innovation. Our energy innovations are legendary, as are our innovations in space," says Texas Governor Greg Abbott, naming several of the state's innovative accomplishments. "Long before all of this innovation we're seeing now, Texas was the home of the Texas Medical Center."

Mayor Sylvester Turner spoke to the importance of collaboration.

"Individually, you can do things very well. Collectively, you can be transformational," he says. "One thing about this city, collaboration is the key. When we play well together, and when we build an integrated, robust ecosystem, everyone wins. That's Houston, and that's the way we operate."

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
