What this Trial Is About

In this study the aim is to investigate whether transfer of the microbiota of either responder or non-responder patients via fecal microbiotica transplantation (FMT) can convert the response to immunotherapy in immune checkpoint inhibitors (ICI) refractory metastatic melanoma patients. This is a randomized double-blind intervention phase Ib/IIa trial in ICI refractory metastatic melanoma patients receiving either FMT of an ICI responding or FMT from an ICI non-responding donor, in combination with ICI. Following randomization, patients will receive vancomycin 250 mg, four times daily for 4 days (day -5 up until day -2), and undergo bowel clearance on day -1 (in total 1L MoviPrep). The FMT, either derived from donor group R (who showed a good response on anti-PD-1 therapy) or donor group NR (who showed progression on anti-PD-1 therapy), will be performed by a gastroenterologist using esophagogastroduodenoscopy. A total amount of 198mL (containing a total of 60 gram feces) will be used for transplantation. Anti-PD-1 treatment will be continued according to the patient's regular treatment schedule. Evaluation of safety and response to treatment will be performed.

Eligibility Criteria

Eligible

You may qualify if you...

  • Patients should be 18 years or older
  • Patients have pathologically confirmed advanced stage cutaneous melanoma (stage III or IV) requiring systemic treatment with anti-PD-1
  • For stage IV disease, only patients with M1a or M1b disease are eligible
  • Patients have confirmed disease progression (≥20% increase by RECIST 1.1) on two scans at least four weeks apart while on anti-PD-1 treatment
  • The second scan must be within 3 weeks prior to signing informed consent
  • Patients must have measurable disease per RECIST 1.1 criteria
  • Patients have an ECOG performance status of 0-1
  • Patients have a life expectancy of more than 3 months
  • Patients have adequate organ function based on lab tests including ALAT/ASAT less than three times the upper limit of normal, creatinine clearance 50 ml/min or higher, total bilirubin ≤20 micromol/L (or ≤50 micromol/L if Gilbert's Syndrome)
  • Patients have an LDH level of 1 times ULN or less
  • Patients of both genders must agree to use highly effective birth control during treatment
  • Patients must be able to understand and sign the informed consent document
Not Eligible

You will not qualify if you...

  • Patients with acral, uveal, mucosal melanoma, or unknown primary melanoma
  • Patients who have received melanoma treatment other than anti-PD-1
  • Stage IV patients with M1c or M1d disease
  • Patients with autoimmune diseases including inflammatory bowel disease, ulcerative colitis, or Crohn's disease (except Hashimoto thyroiditis, vitiligo, history of psoriasis without active disease)
  • Patients with grade 3 or 4 immune-related adverse events requiring active immunosuppressive medication, except stable endocrinopathies on hormone replacement
  • Patients with brain or leptomeningeal metastasis
  • Patients with elevated LDH levels
  • Patients who had major gastric, esophageal, or bowel surgery (like Whipple procedure or subtotal colectomy)
  • Patients with severe food allergies (e.g., nuts, shellfish)
  • Patients with swallowing disorders or bowel passage problems such as ileus, fistulas, or perforation
  • Patients unable to swallow 2 liters of bowel lavage solution
  • Patients with life expectancy less than three months
  • Patients with severe cardiac or pulmonary conditions as judged by the investigator
  • Women who are pregnant or breastfeeding
  • Patients with active systemic infections, coagulation disorders, or other major illnesses
  • Patients with other cancers unless adequately treated and cancer-related life expectancy over 5 years
  • Patients treated with antibiotics in the three months before enrollment or expected to need antibiotics during the study
