Food Allergies

Harvard University

Completed Trials
Pending regulatory approval, please check back for additional updates.

A Phase 1, open label trial demonstrated the safety of Fecal Microbiota Transplants in peanut allergic patients. 30% of patients increased their amount of peanut protein they consumed without reaction.

A secondary trial was completed, including an antibiotic treatment prior to the administration of FMT. In this trial, 60% patients improved their peanut protein reactivity after one FMT.

Future trials are in planning to evaluate the efficacy of prolonged administration of FMT.

Autism

Arizona State University
Completed Trials
Pending regulatory approval, please check back for additional updates.

Investigators are researching the impact of Microbiota Transfer Therapy on Autism and gastrointestinal symptoms in patients with Autism. A phase 1 clinical trial found Autism symptoms reduced nearly 50% two years after microbiota therapy. Read more about the initial trial.

Additional information about the Autism Research Program at Arizona State University is available here.

ASU Researchers Dr. James Adams& Dr. Rosa Krajmalnik-Brown share results from their research.

Pitt-Hopkins Syndrome

Arizona State University
Trials underway
Pending regulatory approval, please check back for additional updates.

Dr. Adams and Dr. Krajmalnik-Brown led a Phase 2, double-blind, placebo-controlled trial assessing the impact of Microbiota Transfer Therapy in patients with Pitt-Hopkins Disease, a genetic disease associated with a severe form of Autism. The study demonstrated microbiota transfer therapy is safe in Pitt-Hopkins patients with improvements in gastrointestinal and Pitt-Hopkins symptoms. The FDA is currently reviewing the treatment protocol for approval. Another trial is in development with a next-generation microbiota therapeutic to allow more patients access who are unable to swallow the standard microbiota therapeutic capsules.

Complications of Intensive Chemotherapy for Acute Leukemia

University of Minnesota
Completed Trials
Pending regulatory approval, please check back for additional updates.

A randomized, double-blind, placebo controlled trial investigating the impact of microbial restoration on patients being treated with intensive chemotherapy for acute leukemia. Study details are available here. Initial findings indicate Microbiota Transplant Therapy is safe in this patient population. A phase 2, randomized, double-blind trial found the patients receiving the active MTT therapy had a lower rate of infection than the placebo group.

Researchers are preparing for a third clinical trial to investigate whether FMT after an allogenic stem cell transplant, when compared to placebo, can prevent Acute-Versus-Host disease.

Recurrent C. difficile Infection: Bacterial Engraftment after Intestinal Microbial Transplant

University of Minnesota
Completed Trials
Pending regulatory approval, please check back for additional updates.
  • In this trial, researchers monitored stool samples of patients successfully treated with Intestinal Microbiota Transplant capsules for recurrent C. difficile infections over a period of a year. All patients recovered clinically and none had exposure to antibiotics after transplant during the trial period.
  • The majority of patients' microbiota resembled that of the donor throughout the entire period. However, in a quarter of patients the microbiota became entirely different from the donor at one year. In a minority of patients we did not see much in the way of donor microbiota at all.

Dietary Factors in Ulcerative Colitis

University of Minnesota
Completed Trials
Pending regulatory approval, please check back for additional updates.
  • Investigators studied the connection between high levels of Hydrogen sulfide, sulfate reducing bacteria and inflammation in Ulcerative Colitis patients. The study suggests that "the increasing severity of inflammation in Ulcerative Colitis is due to the dilution of beneficial factors, concentration of toxic factors and changing detoxification capacity of the host, all of which are intimately linked to the nutrient flow from the diet." Read the full literature review here.

Acute Leukemia: Chemotherapy & Gut Dysbiosis

University of Minnesota
Completed Trials
Pending regulatory approval, please check back for additional updates.
  • Researchers tracked the microbial communities of patients undergoing intensive chemotherapy for Acute leukemia and monitored the impact on the diversity of the gut microbiome. Investigators followed two groups of patients, those completing their first induction of chemotherapy and those undergoing repeat therapy.
  • The study found "larger departures of microbial communities from the pre-chemotherapy baseline during repeat therapy compared to first induction."

Impact of Dietary Sulfur on Intestinal Sulfate Reducing Bacteria

University of Minnesota
Completed Trials
Pending regulatory approval, please check back for additional updates.
  • Researchers studied the impact of diet on intestinal Sulfate Reducing Bacteria. This pilot crossover study monitored the gut bacteria of four healthy individuals, who followed two interventional diets for 10-14 days, containing high or low sulfur-containing amino acids (SAA). No major changes occurred in the quantity of Sulfate Reducing Bacteria, suggesting that "dietary interventions alone may be insufficient for rapid therapeutic targeting of Sulfate Reducing Bacteria." Read the trial publication here.

Graft-Versus-Host Disease

University of Minnesota
Completed Trials
Pending regulatory approval, please check back for additional updates.
  • Researchers studied biomarkers of patients prior to Hematopoietic Cell Transplantation (HCT). Compared to 16 healthy control patients, "pre-transplant patients came to transplant with abnormal levels of all three biomarkers, reflecting residual damage from prior chemotherapy." The study suggests that pre-HCT interventions to the gut microbiome may decrease patient risk for Graft-Versus-Host disease post HCT. Read the study publication here.
  • Hear more about Graft versus Host disease from Dr. Shernan Holtan, researcher at the University of Minnesota.

Acute Leukemia: Chemotherapy & Gut Dysbiosis

University of Minnesota
Completed Trials
Pending regulatory approval, please check back for additional updates.
  • This trial is an observational study monitoring the length of microbial disruption after chemotherapy and rounds of antibiotics for cancer treatment. Researchers found that microbial communities were "stressed beyond its ability to recover", even after antibiotics treatments ended.
