C Diff Drug Development

Delivering drugs to gut tumors can be tricky. Researchers at Washington University in St. | Delivering drugs to gut tumors can be tricky. Researchers at Washington University in St. Louis have engineered an oral probiotic yeast to do the work for them, with the fungal cells able to release immune checkpoint inhibitors that shrank intestinal tumors in mice with colorectal cancer.

Patients in British hospitals with serious, antibiotic-resistant gut infections have little in common with snakebite victims overseas. But when scientists made an unlikely connection in 2018, it led to trials for a potential new treatment for antibiotic-resistant infections. In this …

Vaginal microbiome specialist Freya Bioscience ApS has added $11.8 million to its series A, bringing the total for the round to $50 million. Of the additional $11.8 million, $10.4 million comes from the Gates Foundation and is designated for the development of vaginal microbiome-based immunotherapies for treating bacterial vaginosis, a cause of preterm birth and other pregnancy complications.

Acurx Pharmaceuticals secures FDA agreement for Phase 3 trials of ibezapolstat in C. difficile treatment, showcasing positive microbiome data and international expansion plans.

Recursion and Exscientia, two pioneers in artificial intelligence (AI)-based drug development, have completed a business combination that they vowed will enhance their ability to carry out drug discovery that is both first-in-class and best-in-class.

Clostridioides difficile infection (CDI) recurs in one of five patients. Monoclonal antibodies targeting the virulence factor TcdB reduce disease recurrence, suggesting that an inadequate anti-TcdB response to CDI leads to recurrence. In patients with CDI, we discovered that IL-33 measured at diagnosis predicts future recurrence, leading us to test the role of IL-33 signaling in the induction of humoral immunity during CDI. Using a mouse recurrence model, IL-33 was demonstrated to be integral for anti-TcdB antibody production. IL-33 acted via ST2+ ILC2 cells, facilitating germinal center T follicular helper (GC-Tfh) cell generation of antibodies. IL-33 protection from reinfection was antibody-dependent, as μMT KO mice and mice treated with anti-CD20 mAb were not protected. These findings demonstrate the critical role of IL-33 in generating humoral immunity to prevent recurrent CDI. ### Competing Interest Statement W.P. is a consultant for TechLab, Inc., which manufactures diagnostic tests for CDI.

A stay in a hospital might resolve one health challenge. Still, it may introduce another: an intractable infection with Clostridioides difficile (C difficile), wrote an Editors Summary published in the journal Science in October 2024. This bacteria can thrive and produce toxins if antibiotics hinder the normal gut bacteria.

Clostridioides difficile infection (CDI) is a common cause of antibiotic-associated colitis. C. difficile proliferates and produces toxins that damage the colonic epithelium, leading to symptoms ranging from mild diarrhea to severe pseudomembranous colitis. The host's innate response t …

Working with animals, Penn researchers modified the mRNA vaccine to target C. difficile, an infection that kills 30,000 in the U.S. each year.

The group of large clostridial toxins (LCTs) includes toxins A (TcdA) and B (TcdB) from Clostridioides difficile, hemorrhagic and lethal toxins from Paeniclostridium sordellii, alpha toxin from Clostridium novyi (TcnA), and cytotoxin from Clostridium perfringens. These toxins are associated with sev …

Global difficile-associated diarrhea treatment market size is expected at $5.16 Bn by 2028 at a growth rate of 12.1%.

Using COVID-19 vaccine technology, researchers created an mRNA vaccine targeting C difficile, showing strong immune responses in animal studies.

REC-3964 is designed to treat C. diff by selectively inhibiting the glucosyltransferase activity of toxin B produced by the bacterium in the gastrointestinal tract.

The clinical stage company, Recursion, dosed its first participant using a novel therapy that is not an antimicrobial.

Clostridioides difficile, a spore-forming and anaerobic gram-positive bacterium, causes a wide-spectrum diarrheal disease that can ultimately lead to life-threatening conditions such as toxic megacolon or colonic perforation.

A new vaccine provides hope for treating and even preventing the highly contagious and difficult-to-treat Clostridioides difficile infection, more commonly known as C. difficile or C. diff.

The microbiome therapeutics market is expected to grow from US 375 92 million in 2022 to US 813 38 million by 2030 it is anticipated to record a CAGR of 10 1 from 2022 to 2030 Microbiome Therapeutics Market Size ...

Scientists in Pennsylvania have developed an experimental mRNA-based vaccine for C. diff bacteria, which often cause recurring, miserable bouts of diarrhea.

Promising advancements are on the horizon that could tackle one of the world’s most challenging […]

Bacteria Striking Back Bacterial infections are much less deadly than they used to be before the introduction of antibiotics. “Before we had antibiotics, infections like scarlet fever could even lead to heart problems. Surgery often led to deadly infections in the blood like bacteremia or septicemia. A World Without Antibiotics Because antibiotics silently save so […]

Earlier attempts at producing vaccines against C. difficile have been unsuccessful, although several are currently in development. A vaccine for C. difficile developed by Pfizer failed in a late-stage trial in 2022.
