(BOSTON) — Ovarian cancer is more deadly than any other type of female reproductive organ cancer. It is estimated that in 2024, in the U.S. alone, more than 12,000 women will die from the disease because available therapies are not effective. To help overcome this striking deficit in women’s health, ARPA-H has selected a team at the Wyss Institute at Harvard University as an awardee of its Sprint for Women’s Health effort to develop “iNodes” – implantable lymphoid organs containing patients’ immune cells – as an entirely novel form of personalized immunotherapy to treat ovarian cancer.

 

The dismal outcomes of ovarian cancer are due to the fact that it is typically diagnosed at later stages of the disease: most early ovarian tumors are difficult or impossible to feel in pelvic exams and symptoms can also be caused by less serious conditions, including heartburn, indigestion, and constipation. At the time of diagnosis, about 80% of ovarian cancer patients have developed metastatic disease, and half of these women won’t survive the next five years. 

 

iNodes are based on the important finding that the fortunate minority of ovarian cancer patients who survive the disease frequently develop lymph node-like structures known as “lymphoid organs” in their tumors. Functioning as newly formed immune command centers, these lymphoid organs reprogram the immune system to attack the tumor and retain a long-term immune memory of the tumor in case of its reoccurrence. 

 

“To enable the treatment of ovarian cancer even at more advanced stages, we have developed implantable formulations of human lymphoid organs that could be injected at the operating table right after tumors are removed or directly inside the tumor if it cannot be removed. iNodes can then turn immunologically ‘cold tumors’ into ‘hot tumors’ by kick-starting an active anti-tumor response that sustains the fight against primary or metastatic tumors,” said Wyss Institute Senior Scientist Girija Goyal, Ph.D., who is the Principal Investigator on the iNodes project. “We are extremely excited about the ARPA-H support as it will tremendously accelerate our technology validation and translation into clinical stages and address a significant unmet need for women with ovarian cancer who lack effective treatments.”

 

Women’s health receives nine times less funding and thus suffers from a lower rate of innovation than health issues that affect men or children. Ovarian cancer in particular only receives 1% of the global investment into solid tumor R&D. ARPA-H launched the Sprint for Women’s Health to address critical unmet challenges in women’s health, champion transformative innovations, and tackle health conditions that uniquely or disproportionately affect women. The iNodes concept is supported through the Sprint’s “spark” track, which specifically focuses on early-stage research.

 

iNodes beginnings

Goyal and a team including Wyss Founding Director Donald Ingber, M.D., Ph.D., Lucas Barck, Pranav Prabhala and Sudip Paudel, Ph.D. embarked on the newly minted iNodes project in 2023. Before that the researchers had already supported their early idea to devise a method to create lymphoid organs in vitro by combining biomaterials with immune cells as a 1st year Validation Project. They demonstrated that the immune structures could activate lymphocytes and eliminate immunologically active human lung cancer cells in laboratory assays. Their findings brought Goyal and the team to the key question of whether they could create injectable lymphoid organs or nodes (iNodes) for therapeutic purposes. They successfully secured Validation Project funding for a 2nd year for this therapeutic pivot, and demonstrated that injecting human immune cells mixed with extracellular matrix proteins directly into human tumor masses in mice caused lymphoid organs to form within the tumors. 

 

“Goyal's iNode concept emerged out of her earlier work developing a Lymph Node Chip as part of our long-standing human Organ-on-a-Chip development effort. Driven by the urgent need for new therapies to treat cancers specifically affecting women, she quickly focused the team on ovarian cancer. The ARPA-H Sprint for Women’s Health came at exactly the right time and seemed a wonderful fit for advancing a new type of personalized immunotherapy for this devastating disease,” said Ingber, who is also the Judah Folkman Professor of Vascular Biology at HMS and Boston Children’s Hospital, and the Hansjörg Wyss Professor of Biologically Inspired Engineering at Harvard School of Engineering and Applied Sciences.

 

iNodes for patients

In the ARPA-H-awarded project, the team will de-risk iNodes for ovarian cancer by testing their ability to shrink tumor masses in mice carrying human ovarian tumors, and combining them with other forms of immunotherapy, including immune checkpoint therapies that by themselves have not yet shown the desired efficacy in patients with ovarian cancer but could synergize with iNodes to enhance their effects.

 

“We envision that patients with ovarian cancer could be asked to bank their immune cells ahead of surgeries through simple procedures that are available at most medical centers. iNodes can be created in a short time and injected at tumor sites where they develop into lymphoid organs in a matter of days or a few weeks, instead of the years that natural lymphoid organs can take to develop. This would enable the immune system to be instantly activated against tumors or residual tumor cells to fight recurrence,” said Goyal. 

 

Goyal is joined on the iNodes team by Sudip Paudel, Ph.D., a Postdoctoral Fellow involved in de-risking and further validating the technology; Research Technician Abdul Isaacs; Gretchen Fougere, Ph.D., the Wyss Institute’s Business Director – Healthcare, who focuses on Women’s Health; as well as Samuel Inverso, Ph.D., the Institute’s Director of Business Development – Partnerships.

 

“We believe the iNodes project has the potential to produce an effective and relatively inexpensive solution in the fight against ovarian cancer that could face far fewer hurdles than the complex manufacturing of other personalized cell therapies. It also is a shining example of how we are extending the reach of the burgeoning Women’s Health Catalyst here at the Wyss Institute,” said Ingber.

Sodium butyrate inhibits necroptosis by regulating MLKL via E2F1 in intestinal epithelial cells of liver cirrhosis

Sodium butyrate inhibits necroptosis by regulating MLKL via E2F1 in intestinal epithelial cells of liver cirrhosis
2024-11-12
Background and Aims Necroptosis is critical for regulating intestinal epithelial cells (IECs). Butyric acid (BA), produced during intestinal microbial metabolism, protects the intestinal epithelial barrier. However, whether necroptosis occurs in IECs during liver cirrhosis and whether sodium butyrate (NaB) can regulate necroptosis have not yet been reported. In this study, we aimed to investigate whether IECs undergo necroptosis in cirrhosis and whether NaB can regulate necroptosis and the related regulatory mechanisms. Methods Serum levels of RIPK3, MLKL, and Zonulin, as well as fecal BA levels, were measured and correlated in 48 patients with liver cirrhosis ...

In greening Arctic, caribou and muskoxen play key role

In greening Arctic, caribou and muskoxen play key role
2024-11-12
The story of Arctic greening has overlooked some main characters. At center stage are climate change and warming temperatures. Meanwhile, large grazing wildlife, such as caribou and muskoxen, also play a key role in the timing and abundance of Arctic plants, according to a study from the University of California, Davis. The study, published today in the journal PNAS Nexus, highlights the importance of large herbivores to the Arctic ecosystem, linking grazing with plant phenology and abundance in the Arctic tundra. Phenology is the study of the timing and cyclical patterns in nature, such as when birds migrate, or when a plant first sprouts or blooms. ...

Astronomers’ theory of how galaxies formed may be upended

Astronomers’ theory of how galaxies formed may be upended
2024-11-12
CLEVELAND—The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter helped the earliest stars and galaxies clump together. Instead, the oldest galaxies are large and bright, in agreement with an alternate theory of gravity, according to new research from Case Western Reserve University published Tuesday November 12 in The Astrophysical Journal. The results challenge astronomers’ understanding of the early universe. “What the theory of dark matter predicted is not what we ...
