A Phase 2, Single-Center, Open Label Study of Autologous, Adoptive Cell Therapy Following a Reduced Intensity, Non-myeloablative, Lymphodepleting Induction Regimen in Metastatic Melanoma Patients
Adoptive cell therapy (ACT) with tumor-infiltrating lymphocytes (TILs) in combination with lymphodepletion and high-dose interleukin 2 (IL-2) has demonstrated reproducible objective response rates of approximately 50 percent in patients with highly advanced, refractory metastatic melanoma. Recent developments in theTIL ACT procedure facilitate the use of a reduced-intensity, non-myeloablative, lympho-depleting preparative regimen which is expected to be both less toxic and equally efficient compared to previous regimens. Recently patients recruited post Anti PD-1 therapy had inferior responses in comparison to the pre immune checkpoint inhibitors era. Therefore 2 new arms were added: 1. TIL-ACT with combination of 2 doses of Nivolumab fixed dose 480mg, pre and post TIL. 2. TIL-ACT with FMT given using colonoscopy once and 2 maintenance doses of 12 orally ingested capsules, concurrently with a single dose of Ipilimumab 1 mg/kg up to 100 mg.
• Measurable metastatic Melanoma with at least one lesion that is resectable for TIL generation.
• Refractory to standard treatment
• Patients with one or more brain metastases less than 1 cm each, and any patients with 1 or 2 brain metastases greater than 1 cm must have been treated and stable for 6 weeks.
• Greater than or equal to 18 years of age.
• Willing to practice birth control from the start of chemotherapy until 120 days after release from the hospital.
• Clinical performance status of ECOG 0 or 1
• Hematology:
• Absolute neutrophil count greater than 1000/mm3 without support of filgrastim Normal WBC (greater than 3000/mm3). Hemoglobin greater than 8.0 g/dL Platelet count greater than 100,000/mm3
• Serology:
• Seronegative for HIV antibody. Seronegative for Hepatitis B or Hepatitis C.
• Chemistry:
• Serum ALT/AST less than three times the upper limit of normal (ULN). Serum creatinine less than or equal to 1.6 mg/dL Total bilirubin no more than 1.5 times the ULN, except in patients with Gilbert Syndrome who must have a total bilirubin less than 3 mg/dL.
⁃ Negative pregnancy test in women of child bearing potential because of the potentially dangerous effects of the preparative chemotherapy on the fetus.
⁃ More than four weeks must have elapsed since any prior systemic therapy at the time the patient receives the preparative regimen, and patients' toxicities must have recovered to a grade 1 or less (except for toxicities such as alopecia or vitiligo). Patients may have undergone minor surgical procedures with the past 3 weeks, as long as all toxicities have recovered to grade 1 or less.
