Medical office and life sciences projects are making a big splash in Houston’s commercial real estate sector in 2023.

The 42Floors commercial real estate website ranks five Houston-area medical office buildings among the country’s 20 largest medical office projects set to open this year. Meanwhile, 42Floors identifies two Houston developments among the 20 biggest U.S. life sciences projects on tap to debut in 2023.

Leading the list of the largest U.S. medical office buildings scheduled to be completed this year is the $1.3 billion, 400,000-square-foot O’Quinn Medical Tower. Set to open April 14 at the McNair Campus of Baylor St. Luke’s Medical Center, the outpatient facility will adjoin the McNair Hospital Tower, which opened in 2019.

The O’Quinn tower will serve as the new clinical home of the Dan L Duncan Comprehensive Cancer Center. The center is a federally designated facility for cancer care and research.

Highlights of the 12-story O’Quinn tower, southeast of the Texas Medical Center, include:

  • Ambulatory surgery center with 12 operating rooms and 10 endoscopy suites
  • 80-bay setup for infusion therapy
  • More than 70 exam rooms
  • More than 850 parking spaces

In all, five medical office properties in the Houston area made the 42Floors list, representing the highest concentration of major projects in any U.S. metro area that are scheduled to open this year. The four medical office properties joining the O’Quinn tower on the list are:

  • Houston Methodist Sugar Land Medical Office Building 4, 159,252 square feet
  • Kelsey-Seybold Springwoods Village Campus, 157,983 square feet
  • Kelsey-Seybold Ambulatory Surgery Center in Clear Lake, 116,000 square feet
  • 1715 Project in Friendswood, 107,000 square feet

A separate 42Floors list ranks Dynamic One, part of Baylor College of Medicine’s TMC Helix Park, as the second largest life sciences project in the U.S. set to come online this year. Houston’s TMC3 Collaborative Building lands at No. 19.

The 12-story Dynamic One project will feature lab space, offices, restaurants, and stores. It represents the first of four buildings planned for the 37-acre, five-million-square-foot TMC Helix Park, which is projected to generate an economic impact of $5.4 billion.

The 42Floors list puts the square footage of Dynamic One’s north tower at 365,000. Organizations involved in the project cite the square footage as 355,000.

The Baylor College of Medicine has signed up as Dynamic One’s anchor tenant. It will occupy 114,000 square feet of lab and office space.

“Baylor College of Medicine is a major force in life sciences discovery and commercialization at TMC. Their move to TMC Helix Park will serve as a catalyst for enhanced collaboration with TMC’s other esteemed Institutions, as well as with industry leaders from around the world,” Bill McKeon, president and CEO of TMC, says in a news release.

Also located at TMC Helix Park, the four-story TMC3 Collaborative Building will span 250,000 square feet. It will contain research facilities for MD Anderson Cancer Center, the Texas A&M University Health Science Center, the University of Texas Health Science Center at Houston, and TMC.

In addition, the TMC3 Collaborative Building will house life sciences companies, the TMC Data Collaborative, the TMC Venture Fund, the Braidwell hedge fund, and venture capital and private equity firms.

Pivotal new cancer research tower tops off in the Texas Medical Center

coming soon

Anew structure aimed at greatly expanding medical services and outpatient care to residents of Greater Houston recently topped off.

At an official ceremony attended by VIPs and industry names, Baylor St. Luke's Medical Center toasted the completion of the concrete structure pivotal in the construction of the O'Quinn Medical Tower at the McNair Campus.

This new 12-story O'Quinn Medical Tower at Baylor St. Luke's - McNair Campus will be the new clinical home for the Dan L Duncan Comprehensive Cancer Center, per a release. The center is nationally ranked for cancer care by U.S. News & World Report and is one of only three National Cancer Institute-designated comprehensive cancer centers in Texas. It earned that designation through Baylor College of Medicine.

Additionally, the O'Quinn Medical Tower is part of the expanding McNair Campus. This campus promises more than 400,000 square feet of space to support and provide personalized care to patients and families, including another hospital bed tower and ambulatory care center, press materials describe.

Those familiar with the area will recognize that the campus sits directly adjacent to the planned site of TMC3, a new 37-acre campus that will be located between Old Spanish Trail and Brays Bayou.

"The new O'Quinn Tower and its designation as the clinical home of Baylor's Dan L Duncan Comprehensive Cancer Center will be an important milestones in Baylor's mission," said Dr. Paul Klotman, president, CEO and executive dean of Baylor College of Medicine, in a release. "The McNair Campus is the hub of our clinical activity, and we look forward to the continued expansion."

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
