3. Melanoma: Irrespective of PD-L1 result and BRAF V600 mutation
7. ICI treatment-refractory subjects as defined by the following criteria:
1. Has received at least 2 cycles of anti-PD-(L)1 therapy either as monotherapy or in combination

You may not be if
1. Cancer type and genomic tumor aberrations:
1. NSCLC subjects with EGFR or ALK genomic tumor aberrations
2. HNSCC subjects with nasopharyngeal cancer
2. For ICI refractory/relapsed subjects: Immune related AEs ≥Grade 3 that led to discontinuation of prior immune-modulatory agents including PD-1/PD-L1 inhibitors

16. Have allergy to clindamycin, erythromycin, and ampicillin
17. Has signs and symptoms of colitis at screening
18. Infection requiring systemic antibacterial, antifungal, or antiviral therapy within 14 days before study treatment (Note: Antiviral therapy is permitted for subjects with chronic HBV or HCV infection)
19. Untreated chronic hepatitis B or chronic HBV carriers with HBV DNA\>500 IU/mL (or \>2500 copies/mL) at screening (Note: Inactive hepatitis B surface antigen (HbsAg) carriers, treated and stable hepatitis B (HBV DNA \< 500 IU/mL or \< 2500 copies/mL) can be enrolled. Subjects with detectable HbsAg or detectable HBV DNA should be managed per treatment guidelines. Subjects receiving antivirals at screening should have been treated for \> 2 weeks before study treatment.)
20. With active hepatitis C (Note: Subjects with a negative HCV antibody test at screening or positive HCV antibody test followed by a negative HCV ribonucleic acid (RNA) test at screening are eligible. The HCV RNA test will be performed only for subjects testing positive for HCV antibody. Subjects receiving antivirals at screening should have been treated for \> 2 weeks before study treatment.)
21. Known history of HIV infection
22. History of active inflammatory bowel disease with diarrhea believed to be caused by active inflammatory bowel disease in the past 12 months
23. Major surgery for any reason, except diagnostic biopsy, within 4 weeks of study informed consent and or if the subject has not fully recovered from the surgery within 4 weeks of informed consent
24. History of major gastrointestinal surgery
25. History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial
