With a veteran of the biopharmaceutical industry now aboard as its CEO and an executive at pharmaceutical giant AstraZeneca now serving on its board, Houston-based biopharmaceutical company Pulmotect Inc. is poised for progress.

In September, Dr. Colin Broom joined Pulmotect as CEO. He previously was CEO of Ireland-based Nabriva Therapeutics plc, a biopharmaceutical company that went public in 2015. During Broom's tenure at Nabriva, he helped develop the recently approved drug Xenleta, which treats bacterial pneumonia. Before that, he was chief scientific officer at Pennsylvania-based pharmaceutical company ViroPharma Inc., which Massachusetts-based Shire plc purchased for $4.2 billion in 2014.

Broom's hiring came on the heels of Kumar Srinivasan being named to Pulmotect's board of directors. Srinivasan is vice president of United Kingdom-based AstraZeneca and is its global head of business development and licensing for biopharmaceuticals R&D.

Researchers at MD Anderson Cancer Center and Texas A&M University invented Pulmotect's main product, PUL-042, which holds patents in nine countries. Pulmotect, founded in 2007, emerged from Houston's Fannin Innovation Studio, which nurtures early stage companies in the life sciences sector.

"Attracting such a highly regarded and proven CEO as Colin is a clear signal of the power and potential of Pulmotect's development program," Pulmotect's executive chairman, Leo Linbeck III, founder and chairman of Fannin, says in a release. "Under his leadership, I'm confident that we will advance our technology further into the clinic and closer to the marketplace. His addition is a real game-changer for the company."

Both Broom and Srinivasan are focusing on clinical trials for Pulmotect's PUL-042 product, an inhaled therapy that holds the potential to prevent or treat respiratory infections caused by bacteria, viruses, or fungi. The current Phase 2 trial is evaluating the effectiveness of PUL-042 in treating patients with mild chronic obstructive pulmonary disease (COPD) who've been exposed to a respiratory virus. The current trial is supposed to be followed by additional Phase 2 trials.

COPD, which affects 30 million Americans, is the No. 3 cause of death in the U.S., according to the COPD Foundation. Pulmotect says 40 percent of COPD-related costs could be avoided by preventing complications and hospitalizations, which typically result from COPD problems triggered by a bacterial or viral infection. PUL-042 could substantially decrease those complications, the company says.

Pulmotect seeks to gear PUL-042 toward patients with cancer who are undergoing chemotherapy, as their weakened immunity makes them highly susceptible to pneumonia, Broom says. If the product proves effective with those patients, then people at risk of developing respiratory infections also might benefit from it, including COPD patients and flu patients, he says.

To date, Pulmotect has raised more than $28 million in funding. That includes about $18 million in research grants, including a $7 million grant from the Cancer Prevention and Research Institute of Texas, as well as seven grants from the Small Business Innovation Research program.

Two of Pulmotect's three full-time employees work in Houston, and a team of consultants supports their work, Broom says. A small number of employees might be added during the current Phase 2 trial. Hiring would need to be ramped up if the Phase 2 trial demonstrates that PUL-042 works, he says.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

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.
