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.

Rice research breakthrough paves the way for advanced disease therapies

study up

Bioengineers at Rice University have developed a “new construction kit” for building custom sense-and-respond circuits in human cells, representing a major breakthrough in the field of synthetic biology, which could "revolutionize" autoimmune disease and cancer therapeutics.

In a study published in the journal Science, the team focused on phosphorylation, a cellular process in the body in which a phosphate group is added to a protein, signaling a response. In multicellular organisms, phosphorylation-based signaling can involve a multistage, or a cascading-like effect. Rice’s team set out to show that each cycle in a cascade can be treated as an elementary unit, meaning that they can be reassembled in new configurations to form entirely novel pathways linking cellular inputs and outputs.

Previous research on using phosphorylation-based signaling for therapeutic purposes has focused on re-engineering pathways.

“This opens up the signaling circuit design space dramatically,” Caleb Bashor, assistant professor of bioengineering and biosciences and corresponding author on the study, said in a news release. “It turns out, phosphorylation cycles are not just interconnected but interconnectable … Our design strategy enabled us to engineer synthetic phosphorylation circuits that are not only highly tunable but that can also function in parallel with cells’ own processes without impacting their viability or growth rate.”

Bashor is the deputy director for the Rice Synthetic Biology Institute, which launched last year.

The Rice lab's sense-and-respond cellular circuit design is also innovative because phosphorylation occurs rapidly. Thus, the new circuits could potentially be programmed to respond to physiological events in minutes, compared to other methods, which take hours to activate.

Rice’s team successfully tested the circuits for sensitivity and their ability to respond to external signals, such as inflammatory issues. The researchers then used the framework to engineer a cellular circuit that can detect certain factors, control autoimmune flare-ups and reduce immunotherapy-associated toxicity.

“This work brings us a whole lot closer to being able to build ‘smart cells’ that can detect signs of disease and immediately release customizable treatments in response,” Xiaoyu Yang, a graduate student in the Systems, Synthetic and Physical Biology Ph.D. program at Rice who is the lead author on the study, said in a news release.

Ajo-Franklin, a professor of biosciences, bioengineering, chemical and biomolecular engineering and a Cancer Prevention and Research Institute of Texas Scholar, added “the Bashor lab’s work vaults us forward to a new frontier — controlling mammalian cells’ immediate response to change.”

Houston biotech company tests hard-to-fight cancer therapeutics

fighting cancer

A Houston-based, female-founded biotech company has developed a treatment that could prove to be an effective therapy for a rare blood cancer.

Cellenkos Therapeutics has completed promising Phase 1b testing of its Treg cell therapy, CK0804, in the fight against myelofibrosis. According to a news release from the Cellenkos team, the use of its cord-blood-derived therapeutics could signal a paradigm shift for the treatment of this hard-to-fight cancer.

Cellenkos was founded by MD Anderson Cancer Center physician and professor Simrit Parmar. Her research at the hospital displayed the ability of a unique subset of T cells’ capability to home in on a patient’s bone marrow, restoring immune balance, and potentially halting disease progression.

Myelofibrosis has long been treated primarily with JAK (Janus Kinase) inhibitors, medications that help to block inflammatory enzymes. They work by suppressing the immune response to the blood cancer, but don’t slow the progression of the malady. And they’re not effective for every patient.

“There is a significant need for new therapeutic options for patients living with myelofibrosis who have suboptimal responses to approved JAK inhibitors,” Parmar says. “We are greatly encouraged by the safety profile and early signs of efficacy observed in this patient cohort and look forward to continuing our evaluation of the clinical potential of CK0804 in our planned expansion cohort.”

The expansion cohort is currently enrolling patients with myelofibrosis. What exactly are sufferers dealing with? Myelofibrosis is a chronic disease that causes bone marrow to form scar tissue. This makes it difficult for the body to produce normal blood cells, leaving patients with fatigue, spleen enlargement and night sweats.

Myelofibrosis is rare, with just 16,000 to 18,500 people affected in the United States. But for patients who don’t respond well to JAKs, the prognosis could mean a shorter span than the six-year median survival rate outlined for the disease by Cleveland Clinic.

Helping myelofibrosis patients to thrive isn’t the only goal for Cellenkos right now.

The company seeks to aid people with rare conditions, particularly inflammatory and autoimmune disorders, with the use of CK0804, but also other candidates including one known as CK0801. The latter drug has shown promising efficacy in aplastic anemia, including transfusion independence in treated patients.

The company closed its $15 million series A round led by BVCF Management, based in Shanghai, in 2021. Read more here.

Clinical-stage Houston cell therapy company closes $28.4M oversubscribed series A

cha-ching

An emerging biotech company in Houston has closed its series A with outsized success.

March Biosciences' oversubscribed raise brought in $28.4 million of financing with Mission BioCapital and 4BIO Capital leading the pack of investors. The company has now raised more than $51 million in total.

Last year, March Biosciences announced its strategic alliance with CTMC (Cell Therapy Manufacturing Center), a joint venture between MD Anderson Cancer Center and National Resilience. CEO Sarah Hein met her co-founder, Max Mamonkin, at the TMC Accelerator for Cancer Therapeutics. Along with fellow co-founder Malcolm Brenner, March Biosciences launched from the Center for Cell and Gene Therapy (Baylor College of Medicine, Houston Methodist Hospital and Texas Children’s Hospital). Its goal is to fight cancers that have been unresponsive to existing immunotherapies using its lead asset, MB-105.

An autologous CD5-targeted CAR-T cell therapy, MB-105 is currently in phase-1 trials in patients with refractory T-cell lymphoma and leukemia. The treatment is showing signs of being both safe and effective, meriting a phase-2 trial that will begin early next year. The funds raised from the series A will help to finance the Phase 2 clinical development of MB-105 to expand on the existing data with optimized manufacturing processes.

“This oversubscribed financing enables us to advance our first-in-class CAR-T therapy, MB-105, into a Phase 2 trial for T-cell lymphoma – an indication with an exceptionally poor prognosis and few treatment options,” says Hein. “With the support and confidence of our investors, we are not only advancing our lead program but also expanding our pipeline, underscoring our commitment to delivering best-in-class therapies to patients that can change the treatment paradigm for these challenging cancers.”

But that’s not the only exciting news that Hein and her associates have to report. March Biosciences has recently partnered with cell therapy venture studio, Volnay Therapeutics. Led by highly experienced cell therapy development veterans, the March Biosciences team will work to develop a scalable manufacturing process for MB-105 that will lead to commercialization. Volnay co-founder and CEO Stefan Wildt, who held key R&D leadership positions in cell and gene therapy units at Novartis and Takeda, has also joined the board of March Biosciences. The board of directors is also welcoming Cassidy Blundell of Mission BioCapital and Owen Smith of 4BIO Capital.

“The team at March Biosciences is leveraging powerful science and promising clinical data to tackle cancers with significant unmet need,” says Blundell, a partner at Mission BioCapital. “We're excited to support their journey and believe their focused approach with MB-105 could lead to significant breakthroughs in the CAR-T space.”

The Houston-born company, which is a finalist for the 2024 Houston Innovation Awards, continues to accelerate quickly, in part thanks to its home base. After all, existing local investors like TMC Venture Fund also participated in the new raise. As Hein said last year, “Working with partners here in Houston, we have all the pieces and the community rises to the occasion to support you.”

Houston oncology therapeutics co. raises $11.4M in seed funding

money moves

A Houston-based, clinical-stage immuno-oncology company has raised an oversubscribed round of seed funding.

Diakonos Oncology Corp. closed its seed round to the tune of $11.4 million. The funding will go toward supporting the company's Phase 2 trial — slated for later this year, following its ongoing Phase 1 study — and operations through late next year. California-based biotechnology investment firm Restem Group Inc. led the round, and existing investors contributed as well.

“We greatly appreciate the support of these investors in sharing our passion for improving the lives of patients suffering from deadly cancers such as glioblastoma,” Mike Wicks, Diakonos CEO, says in a news release. “The fact that this financing is nearly triple our initial target also shows they share our confidence in the effectiveness of our unique cancer therapy.”

Founded in 2016, the company recently received FDA Fast Track designation for its dendritic cell vaccine, DOC1021, which targets glioblastoma multiforme, or GBM, the most common and most lethal malignant brain tumor in adults. Diakonos also received the designation for its pancreatic cancer treatment.

"We are thrilled to invest in this groundbreaking company that is at the forefront of cancer treatment innovation. As a firm deeply involved in the cell therapeutic field, we recognize the immense potential of their pioneering work with dendritic cell therapies and we are confident that this can become a new standard of care for cancer in the future," adds Andres Isaias, executive chairman of Restem Group Inc.

Diakonos Oncology's 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. According to the company, all of the patients who have tried the treatment have exceeded survival expectations. And DOC1021 appears to be extremely safe, with no serious adverse effects having been reported.

Texas ranks as No. 1 most financially distressed state, says new report

Money Woes

Experiencing financial strife is a nightmare of many Americans, but it appears to be a looming reality for Texans, according to a just-released WalletHub study. It names Texas the No. 1 most "financially distressed" state in America.

To determine the states with the most financially distressed residents, WalletHub compared all 50 states across nine metrics in six major categories, such as average credit scores, the share of people with "accounts in distress" (meaning an account that's in forbearance or has deferred payments), the one-year change in bankruptcy filings from March 2024, and search interest indexes for "debt" and "loans."

Joining Texas among the top five most distressed states are Florida (No. 2), Louisiana (No. 3), Nevada (No. 4), and South Carolina (No. 5).

Texas' new ranking as the most financially distressed state in 2025 may be unexpected, WalletHub says, considering the state has a "bigger GDP than most countries" and still has one of the top 10 best economies in the nation (even though that ranking is also lower than it was in previous years).

Even so, Texas residents are stretching themselves very thin financially this year. Texans had the ninth lowest average credit scores nationwide during the first quarter of 2025, the study found, and Texans had the sixth-highest increase in non-business-related bankruptcy filings over the last year, toppling 22 percent.

"Texas also had the third-highest number of accounts in forbearance or with deferred payments per person, and the seventh-highest share of people with these distressed accounts, at 7.1 percent," the report said.

This is where Texas ranked across the study's six key dimensions, where No. 1 means "most distressed:"

  • No. 5 – "Loans" search interest index rank
  • No. 6 – Change in bankruptcy filings from March 2024 to March 2025 rank
  • No. 7 – Average number of accounts in distress rank
  • No. 8 – People with accounts in distress rank
  • No. 13 – Credit score rank and “debt” search interest index rank
Examining these financial factors on the state level is important for understanding how Americans are faring with economic issues like inflation, unemployment rates, or natural disasters, according to WalletHub analyst Chip Lupo.


"When you combine data about people delaying payments with other metrics like bankruptcy filings and credit score changes, it paints a good picture of the overall economic trends of a state," Lupo said.

On the other side of the spectrum, states like Hawaii (No. 50), Vermont (No. 49), and Alaska (No. 48) are the least financially distressed states in America.

The top 10 states with the most people in financial distress in 2025 are:

  • No. 1 – Texas
  • No. 2 – Florida
  • No. 3 – Louisiana
  • No. 4 – Nevada
  • No. 5 – South Carolina
  • No. 6 – Oklahoma
  • No. 7 – North Carolina
  • No. 8 – Mississippi
  • No. 9 – Kentucky
  • No. 10 – Alabama

Digital Health Institute's new exec director aims to lead innovation and commercialization efforts

new hire

Though our existences have become deeply entangled with technology, our health has been slower to catch up. The creation late last year of the Digital Health Institute was a major step into the future for both Rice University and Houston Methodist, for whom the institute is a joint venture.

The latest news for the Digital Health Institute is the appointment of Pothik Chatterjee to the role of executive director.

“The Digital Health Institute’s collaborative model is uniquely powerful,” Chatterjee told Rice University’s office of media relations. “By bringing together clinicians, engineers and entrepreneurs, we’re building an ecosystem designed to transform how care is delivered and experienced.”

Chatterjee’s role is to help grow the collaboration between the institutions, but the Digital Health Institute already boasts more than 20 active projects, each of which pairs Rice faculty and Methodist clinicians.

“Research is great, but what we really want at the Digital Health Institute is to translate those research findings into products and services that can be used at the patient's bedside,” Chatterjee explained to InnovationMap.

Once the research is in place, it’s up to Chatterjee to find commercial opportunities within the research portfolio. Those include everything from hospital-grade medical imaging wearables to the creation of digital twins for patients to help better treat them.

“As we move from vision to execution, Pothik’s expertise will be essential in helping us strengthen the institutional alignment needed to deliver at scale,” Dr. Khurram Nasir, Methodist’s William A. Zoghbi Centennial Chair in Cardiovascular Medicine and division chief of cardiovascular prevention and wellness, told Rice. “From my vantage point of a health system, the real value lies not just in innovation, but in implementation.”

Nasir’s co-founder is Ashutosh Sabharwal, Rice’s Ernest Dell Butcher Professor of Engineering and professor of electrical and computer engineering.

“The Digital Health Institute is a key step toward advancing health and health care for the benefit of humanity,” Sabharwal said. “We’re thrilled to welcome Pothik to our growing team. His background in health care innovation, research administration and venture investing will be instrumental in translating cutting-edge research into impactful digital health solutions. From leading innovation strategy and forging strong partnerships to driving fundraising and grant development, his leadership will help shape the institute’s long-term success.”

Though Chatterjee has previously worked around the country, including in Boston and Baltimore, he says he believes Houston is uniquely positioned to thrive in the digital health space.

“Houston is the best place to do it, because we have Rice and Houston Methodist,” he told InnovationMap. “[People] want to help keep that innovation in Houston, not just send it off to Silicon Valley or New York or Boston. There seems to be a lot of appetite from the philanthropic community to have homegrown Houston digital health innovation.”
