Role of Gut Microbiome and Fecal Transplant on Medication-Induced GI Complications in Patients With Cancer
What this study is about
This trial studies the role of the gut microbiome and effectiveness of a fecal transplant on medication-induced gastrointestinal (GI) complications in patients with melanoma or genitourinary cancer.
View original scientific description
This trial studies the role of the gut microbiome and effectiveness of a fecal transplant on medication-induced gastrointestinal (GI) complications in patients with melanoma or genitourinary cancer. The gut microbiome (the bacteria and microorganisms that live in the digestive system) may affect whether or not someone develops colitis (inflammation of the intestines) during cancer treatment with immune-checkpoint inhibitor drugs. Studying samples of stool, blood, and tissue from patients with melanoma or genitourinary cancer may help doctors learn more about the effects of treatment on cells, and help doctors understand how well patients respond to treatment. Treatment with fecal transplantation may help to improve diarrhea and colitis symptoms.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Diagnosis of any stage melanoma, Non-Small Cell Lung Cancer or genitourinary (GU) malignancies (Project 1).
- Diagnosis of any cancer type (Projects 2 and 3)
- Treatment with any ICPI agent
- Ability to understand and willingness to sign an informed consent form and rate surveys
- Life expectancy \> 4 months (Project 3)
- ICPI-related diarrhea and/or colitis of any grade with or without concurrent non- GI toxicity as the toxicity group (project 1)
- Patients with no organ toxicity as the control group (project 1)
- ICPI-related colitis and/or diarrhea of grade ≥ 2 as GI toxicity (initial episode or recurrence) receiving standard treatment of immunosuppressive agents (steroid, infliximab, vedolizumab, or ustekinumab) any time during the colitis disease course until sustained resolution of GI toxicity, or one- year time point after enrollment (Project 2)
- ICPI-related colitis and/or diarrhea of grade ≥ 2 as GI toxicity without involvement of non- GI toxicity within 45 days prior to FMT (Project 3)
- ICPI-related colitis and/or diarrhea of grade ≥ 2 within 45 days prior to FMT with ANY of the following characteristics (project 3): (i) refractory to treatment of steroid and two doses of non-steroidal immunosuppressants e.g. infliximab, vedolizumab or ustekinumab, (ii) contraindication for immunosuppressive treatment, (iii) recurrence after successful initial treatment, (iv) recurrent symptoms once steroid is tapered down/off or diarrhea/colitis symptoms are steroid dependent, or (v) patients with a history of refractory ICPI-related colitis and/or diarrhea to medical treatment, even if they have improved symptoms from supportive care within 45 days prior to FMT
- No concern for active concomitant GI infection for the ICPI diarrhea/colitis work up at the time of protocol therapy initiation as confirmed by stool tests or as per the treating physician based on clinical presentation (project 3)
- Patient who has been cleared for enrollment by Infectious Diseases consultant or treating physician if positive infection workup or screening tests (e.g. lifelong positive T-spot due to BCG inoculation, chronic colonization) prior to initiation of diarrhea/colitis treatment (project 3)
Exclusion criteria
- Age younger than 18 years
- History of inflammatory bowel disease, and/or radiation enteritis or colitis with active disease status at the time of study treatment initiation
- Pregnant and breastfeeding women
- Women of child-bearing potential who have positive urine or serum pregnancy test or refuse to do pregnancy test unless last menstrual cycle was \> 1 year prior to consent and/ or clear documentation states that patient is peri- or post-menopausal or there was recent supporting objective evidence of 'no pregnancy' status (e.g. blood or imaging) within 30 days prior to date of study treatment
- Patients who develop concurrent non- GI toxicity at the time of FMT treatment (project 3)
- Patients with active bacterial or fungal infection (Project 3)
- Donors at risk for monkeypox infection and/ or exposure as determined by a questionnaire (Project 3) Withdrawal Criteria
- Patients may withdraw from the trial at any time
- Patients who develop GI perforation or toxic colitis that require surgery from ICPI colitis
- In project 3, if the first 30% of cases fail the fecal transplant treatment, then project 3 will be terminated
Where
- Houston, Texas
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
