Exclusion Criteria

Presence of absolute contra-indications to FMT administration:Toxic megacolon;Inflammatory bowel disease;Anatomic contra-indications to colonoscopy;Colectomy Patient is currently participating and receiving other study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of this study intervention.

Currently under any form of systemic antibiotics. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (> 10 mg prednisone daily or equivalent) or any other form of immunosuppressive therapy two weeks prior to trial treatment. Patients receiving systemic steroids at physiologic doses are permitted to enroll assuming steroid dose is not above the acceptable threshold (> 10 mg prednisone daily or equivalent).

Has HIV infection or AIDS-related illness. Has active infection of HAV, HBV or HCV. Patients with a history of Hepatitis B/C infection who have received anti-viral therapy and are disease free may be considered for enrollment after discussion with Principal Investigator.

Patient has received a live vaccine within 4 weeks prior to the first dose of treatment. Seasonal influenza vaccines or COVID-19 vaccines for injection are generally inactivated virus vaccines and are allowed.

Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

Primary Outcome Measures
NameTimeMethod
Rate of Disease Controlup to 6 months

Rate of Disease Control is defined as the percentage of subjects who had a complete response (CR), partial response (PR), or stable disease (SD), as defined by ir-RECIST v1.1.

Objective response rate (ORR)up to 6 months

ORR is defined as the percentage of subjects who had a complete response (CR) or partial response (PR), as defined by ir-RECIST v1.1, and is based on the best response obtained.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)up to 2 years

The length of time (in days) from study intervention that participants remain alive.

Quality of life based on the questionnaireup to 2 years

The FACT-GA questionnaire will be used to assess the quality of life of the participants.

Change in the immunityup to 6 months

Mean change from baseline of immune cells compared with 6 months post fecal microbiota transplantation (FMT).

Progression-free Survival (PFS)up to 2 years

The median length of time from initiation of study drug(s) disease progression as defined by RECIST v1.1, or death. Progressive Disease (PD): ≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The sum must also demonstrate an absolute increase of ≥5 mm. The appearance ≥1 new lesion(s) is considered progression.

Change in the intestinal microbiome communityup to 6 months

Mean change from baseline of bacterial species compared with 6 months post fecal microbiota transplantation (FMT).

Incidence of Adverse Events Related to Treatmentup to 6 months

All adverse events and their relationships to study drugs and procedures will be recorded,to assess overall safety, feasibility and tolerability of treatment.
