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.

Houston scientist wins Nobel Prize for breakthrough cancer treatment

Research Recognition

A University of Texas MD Anderson Cancer Center scientist has been lauded for his cancer research. Jim Allison, Ph.D., was announced as the recipient of the 2018 Nobel Prize in Physiology or Medicine on October 1.

Allison, who is the chair of Immunology and executive director of the Immunotherapy Platform, is the first MD Anderson scientist to receive the world's most coveted award for discoveries in the fields of life sciences and medicine. Allison won for his work in launching an effective new way to attack cancer by treating the immune system rather than the tumor, according to a release.

"I'm honored and humbled to receive this prestigious recognition," Allison says in a statement. "A driving motivation for scientists is simply to push the frontiers of knowledge. I didn't set out to study cancer, but to understand the biology of T cells, these incredible cells to travel our bodies and work to protect us."

Allison shares the award with Tasuku Honjo, M.D., Ph.D., of Kyoto University in Japan. When announcing the honor, the Nobel Assembly of Karolinska Institute in Stockholm noted in a statement that "stimulating the ability of our immune system to attack tumor cells, this year's Nobel Prize laureates have established an entirely new principle for cancer therapy."

The prize recognizes Allison's basic science discoveries on the biology of T cells, the adaptive immune system's soldiers, and his invention of immune checkpoint blockade to treat cancer. According to MD Anderson, Allison's crucial insight was to block a protein on T cells that acts as a brake on their activation, freeing the T cells to attack cancer. He developed an antibody to block the checkpoint protein CTLA-4 and demonstrated the success of the approach in experimental models.

Allison's work led to the development of the first immune checkpoint inhibitor drug which would become the first to extend the survival of patients with late-stage melanoma. Follow-up studies show 20 percent of those treated live for at least three years, with many living for 10 years and beyond, unprecedented results, according to the cancer center.

"Jim Allison's accomplishments on behalf of patients cannot be overstated," says MD Anderson president Peter WT Pisters, M.D., in a statement. "His research has led to life-saving treatments for people who otherwise would have little hope. The significance of immunotherapy as a form of cancer treatment will be felt for generations to come."

"I never dreamed my research would take the direction it has," Allison adds. "It's a great, emotional privilege to meet cancer patients who've been successfully treated with immune checkpoint blockade. They are living proof of the power of basic science, of following our urge to learn and to understand how things work."

Houston team develops low-cost device to treat infants with life-threatening birth defect

infant innovation

A team of engineers and pediatric surgeons led by Rice University’s Rice360 Institute for Global Health Technologies has developed a cost-effective treatment for infants born with gastroschisis, a congenital condition in which intestines and other organs are developed outside of the body.

The condition can be life-threatening in economically disadvantaged regions without access to equipment.

The Rice-developed device, known as SimpleSilo, is “simple, low-cost and locally manufacturable,” according to the university. It consists of a saline bag, oxygen tubing and a commercially available heat sealer, while mimicking the function of commercial silo bags, which are used in high-income countries to protect exposed organs and gently return them into the abdominal cavity gradually.

Generally, a single-use bag can cost between $200 and $300. The alternatives that exist lack structure and require surgical sewing. This is where the SimpleSilo comes in.

“We focused on keeping the design as simple and functional as possible, while still being affordable,” Vanshika Jhonsa said in a news release. “Our hope is that health care providers around the world can adapt the SimpleSilo to their local supplies and specific needs.”

The study was published in the Journal of Pediatric Surgery, and Jhonsa, its first author, also won the 2023 American Pediatric Surgical Association Innovation Award for the project. She is a recent Rice alumna and is currently a medical student at UTHealth Houston.

Bindi Naik-Mathuria, a pediatric surgeon at UTMB Health, served as the corresponding author of the study. Rice undergraduates Shreya Jindal and Shriya Shah, along with Mary Seifu Tirfie, a current Rice360 Global Health Fellow, also worked on the project.

In laboratory tests, the device demonstrated a fluid leakage rate of just 0.02 milliliters per hour, which is comparable to commercial silo bags, and it withstood repeated disinfection while maintaining its structure. In a simulated in vitro test using cow intestines and a mock abdominal wall, SimpleSilo achieved a 50 percent reduction of the intestines into the simulated cavity over three days, also matching the performance of commercial silo bags. The team plans to conduct a formal clinical trial in East Africa.

“Gastroschisis has one of the biggest survival gaps from high-resource settings to low-resource settings, but it doesn’t have to be this way,” Meaghan Bond, lecturer and senior design engineer at Rice360, added in the news release. “We believe the SimpleSilo can help close the survival gap by making treatment accessible and affordable, even in resource-limited settings.”

Oxy's $1.3B Texas carbon capture facility on track to​ launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.
