A Houston immuno-oncology company has recently made major headway with the FDA, including both a fast track and an orphan drug designation. It will soon start a phase 2 trial of its promising cancer fighting innovation.

Diakonos Oncology was born in 2016, the brainchild of Baylor researchers already hard at work in the realm of dendritic cell vaccines. Drs. Will Decker, Matt Halpert, and Vanaja Konduri partnered with Dan Faust, a Houston businessman and pharmacist, to bring their treatment to the public, says COO Jay Hartenbach.

The name Diakonos means “deacon or servant in Greek,” he explains. “A lot of companies end up focusing on treating a specific disease or cancer and what you end up having is a significant amount of potential but with a lot of tradeoffs and downsides. And so our goal is we need to eliminate the cancer but we can't harm or dramatically malign the patient in doing so.”

How do they do that? Because the therapy catalyzes a natural immune response, it’s the patient’s own body that’s fighting the cancer. Hartenbach credits Decker with the idea of educating dendritic cells to attack cancer, in this case, glioblastoma multiforme (GBM), one of the most aggressive cancers with which doctors and patients are forced to tangle.

“Our bodies are already very good at responding very quickly and aggressively to what it perceives as virally infected cells. And so what Dr. Decker did was basically trick the immune system by infecting these dendritic cells with the cancer specific protein and mRNA,” details Hartenbach.

But GBM isn’t the only cancer on which Diakonos Oncology has its sights set. Other notably stubborn-to-treat cancers that they’re working on include pancreatic cancer and angiosarcoma. The scientists are focused on meeting unmet medical needs, but also realize that treating such cancers would allow for the fastest determination of whether or not the treatment was effective.

The fast track designation, originally received last fall, means that the drug approval time for DOC1021, Diakonos’ glioblastoma vaccine, will be only six months. But Hartenbach highlights an additional boon, the fact that the special designation also allows for more frequent communications with the FDA.

“That’s very helpful for us, right as we're contemplating how to design the upcoming trials. From a business standpoint, it also is incredibly helpful because it provides a third party validation of what we're doing and the results that we're seeing,” he says.

What they’re seeing includes the survival of 13 out of 16 patients from the initial October 2021 enrollment. The three patients who passed away received the lowest dose of DOC1021. Hartenbach says that the remaining patients are thriving, with no serious adverse effects. With a median survival rate of 15 to 21 months, it’s hard to understate the significance of these patients’ success.

Diakonos Oncology is headquartered in Houston, with a staff of 10 in Space City and an additional eight distributed employees. Hartenbach says that the company’s hometown has been instrumental in its success. He mentions that the robust innovation of the Texas Medical Center meant that as the company has grown, there has never been a motivation to leave Houston.

“You're having a lot of both investment and companies actually moving to Houston,” Hartenbach says. “So we’ve been fortunate to have started there. There are bigger traditional biotech hubs, San Diego, Boston, and San Francisco, but Houston really is now putting itself on the map and it's getting a lot of attention.”

One of the companies responsible for that improved reputation? Diakonos Oncology and its promising approach to aggressive cancers.

Houston immunotherapy company achieves FDA designation for cancer-fighting vaccine

got the green light

The FDA has granted a Houston-based company a Fast Track designation.

Diakonos Oncology Corp. is a clinical-stage immuno-oncology company that has developed a unique dendritic cell vaccine, DOC1021. The vaccine targets glioblastoma multiforme (GBM), the most common and most lethal malignant brain tumor in adults. The aggressive tumors come with a life expectancy of about 15 months following diagnosis. About 7 percent of those diagnosed survive five years, while the 10-year outlook only sees a one-percent survival rate.

“The FDA’s decision acknowledges the potential of this new treatment approach for a very challenging disease,” Diakonos CEO Mike Wicks says in a press release. “Our protocol represents a first for cancer immunotherapy and could be viable for many types of cancers beyond GBM.”

FDA Fast Track designations are intended to expedite the haste with which drugs with early clinical promise are reviewed, likely taking them to market faster.

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.

The technology uses dendritic cells, white blood cells that are able to perceive threats, to its advantage. The unique cancer markers are loaded both internally and externally into the immune cells, just as they would simultaneously occur in a viral infection. The individualized treatment is administered through three precise injections that target deep cervical lymph node chains. By dosing this way, the immune responses are directed straight to the central nervous system.

The results have spoken for themselves: All of the patients who have tried the treatment have exceeded survival expectations. And just as importantly, DOC1021 appears to be extremely safe. No serious adverse effects have been reported.

“Because Phase I clinical trials are generally not statistically powered to demonstrate efficacy, detection of a statistically significant efficacy signal is very promising,” says William Decker, associate professor of immunology at Baylor College of Medicine and inventor of the DOC1021 technology.

The Phase 1 open-label trial of DOC1021 (NCT04552886) is currently taking place at both the University of Texas Health Science Center in Houston and at the MD Anderson Cancer Center at Cooper University Health Care in Camden, NJ. The trial is expected to complete this year.

Houston unicorn closes $421M to fuel first phase of flagship energy project

Heating Up

Houston geothermal unicorn Fervo Energy has closed $421 million in non-recourse debt financing for the first phase of its flagship Cape Station project in Beaver County, Utah.

Fervo believes Cape Station can meet the needs of surging power demand from data centers, domestic manufacturing and an energy market aiming to use clean and reliable power. According to the company, Cape Station will begin delivering its first power to the grid this year and is expected to reach approximately 100 megwatts of operating capacity by early 2027. Fervo added that it plans to scale to 500 megawatts.

The $421 million financing package includes a $309 million construction-to-term loan, a $61 million tax credit bridge loan, and a $51 million letter of credit facility. The facilities will fund the remaining construction costs for the first phase of Cape Station, and will also support the project’s counterparty credit support requirements.

Coordinating lead arrangers include Barclays, BBVA, HSBC, MUFG, RBC and Société Générale, with additional participation from Bank of America, J.P. Morgan and Sumitomo Mitsui Trust Bank, Limited, New York Branch.

“As demand for firm, clean, affordable power accelerates, EGS (Enhanced Geothermal Systems) is set to become a core energy asset class for infrastructure lenders,” Sean Pollock, managing director, project Finance at RBC Capital Markets, said in a news release. “Fervo is pioneering this step change with Cape Station, a vital contribution to American energy security that RBC is proud to support.”

The oversubscribed financing marks Cape Station’s shift from early-stage and bridge funding to a long-term, non-recourse capital structure, according to the news release.

“Non-recourse financing has historically been considered out of reach for first-of-a-kind projects,” David Ulrey, CFO of Fervo Energy, said in a news release. “Cape Station disrupts that narrative. With proven oil and gas technology paired with AI-enabled drilling and exploration, robust commercial offtake, operational consistency, and an unrelenting focus on health and safety, we have shown that EGS is a highly bankable asset class.”

Fervo continues to be one of the top-funded startups in the Houston area. The company has raised about $1.5 billion prior to the latest $421 million. It also closed a $462 million Series E in December.

According to Axios Pro, Fervo filed for an IPO that would value the company between $2 billion and $3 billion in January.

Houston food giant Sysco to acquire competitor in $29 billion deal

Mergers & Acquisitions

Sysco, the nation's largest food distributor, will acquire supplier Restaurant Depot in a deal worth more than $29 billion.

The acquisition would create a closer link between Sysco and its customers that right now turn to Restaurant Depot for supplies needed quickly in an industry segment known as “cash-and-carry wholesale.”

Sysco, based in Houston, serves more than 700,000 restaurants, hospitals, schools, and hotels, supplying them with everything from butter and eggs to napkins. Those goods are typically acquired ahead of time based on how much traffic that restaurants typically see.

Restaurant Depot offers memberships to mom-and-pop restaurants and other businesses, giving them access to warehouses stocked with supplies for when they run short of what they've purchased from suppliers like Sysco.

It is a fast growing and high-margin segment that will likely mean thousands of restaurants will rely increasingly on Sysco for day-to-day needs.

Restaurant Depot shareholders will receive $21.6 billion in cash and 91.5 million Sysco shares. Based on Sysco’s closing share price of $81.80 as of March 27, 2026, the deal has an enterprise value of about $29.1 billion.

Restaurant Depot was founded in Brooklyn in 1976. The family-run business then known as Jetro Restaurant Depot, has become the nation's largest cash-and-carry wholesaler.

The boards of both companies have approved the acquisition, but it would still need regulatory approval.

Shares of Sysco Corp. tumbled 13% Monday to $71.26, an initial decline some industry analysts expected given the cost of the deal.
