A First-in-human (FIH) Combination Treatment Study With a Single Dose Level of BMC128

Study Purpose

The purpose of this study is to assess the safety and tolerability of BMC128 in combination with nivolumab (a known immunotherapy) in order to investigate if administration of select elements of the intestinal microbiome may serve as a novel and effective means of improving the efficacy of anti-cancer immunotherapies.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Exclusion Criteria:

1. History of partial or complete colon resection or colonic dissemination of tumor. 2. Active brain metastases or leptomeningeal disease. Subjects with asymptomatic central nervous system (CNS) metastases which have been stable (defined as without evidence of progression by magnetic resonance imaging (MRI) for at least 42 days prior to enrolment (initiation of depletion phase) and any neurologic symptoms have returned to baseline) following treatment with surgery or radiation therapy are allowed. 3. Prior solid organ or hematologic transplant. 4. Prior treatment with PD1/ PDL-1 inhibitor in combination with an immune-modifying microbiome agent. 5. History of treatment-related immune-mediated (or immune-related) adverse reactions to immune-modulatory agents (including but not limited to anti-PD1/PD-L1 agents, anti-CTLA4 monoclonal antibodies) that caused permanent discontinuation of the agent, or that were grade 3 or 4 in severity. Subjects with grade 3-4 hypothyroidism, primary adrenal insufficiency or diabetes mellitus which are asymptomatic following adequate supplementation, will be eligible. 6. Treatment with chemotherapy, immunotherapy, biologic therapy (except for denosumab and bisphosphonates), or other investigational agents <21 days of enrolment (initiation of depletion phase) 7. Palliative radiotherapy within 14 days or less from enrolment. 8. Comorbidity requiring corticosteroid therapy (>10mg prednisone/day or equivalent) within 7 days of enrolment. Physiologic replacement doses are allowed if they are ≤10mg of prednisone/day or equivalent, as long as they are not being administered for immunosuppressive intent. Inhaled, intranasal or topical steroids are permitted, provided that they are not for treatment of an autoimmune disorder. 9. Significant cardiac disease; New York Heart Association classification for chronic heart failure III-IV, symptomatic coronary artery disease, significant ventricular arrhythmias, myocardial infarction within 6 months, unstable, poorly controlled angina pectoris. 10. Active, known or suspected autoimmune disease that has required systemic treatment within the past 2 years (i.e., with use of disease-modifying agents, corticosteroids or immunosuppressive drugs), except for replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.). Note: corticosteroids given within 24 hours of an imaging study for purposes of pre-medication in subjects with hypersensitivity to radiologic contrast agents are allowed. 11. Serious active infection requiring systemic therapy. 12. Subject has completed a course of antibiotics within the four weeks prior to enrollment. 13. Subjects, who, in the opinion of the investigator, have predisposing risk factors for recurrent infections requiring systemic antibiotic treatment (i.e., fistulae, obstructing pulmonary mass, non-healing wound) 14.

Receipt of a live-virus vaccination within 28 days of enrolment. COVID-19 vaccine is not mandatory.

Known inability to orally ingest capsules

Additional Details

This phase 1, first-in-human, proof-of-concept, open-label, combination treatment study is designed to profile the safety and tolerability of BMC128 in combination with Nivolumab, its effect on the intestinal microbiome and the anti-tumor immune and inflammatory responses and its preliminary anti-tumor activity. A 14-day induction phase, in which patients will be treated with a single dose level of BMC128, will be initiated, followed by four 28-day treatment cycles of BMC128 in combination with Nivolumab. Thereafter, patients will be treated with Nivolumab as a monotherapy for up to 22 additional cycles, until disease progression (PD) or intolerable toxicity

Arms & Interventions


Experimental: BMC128 in combination with Nivolumab

Four 28-day treatment cycles of the standard Nivolumab treatment protocol (480 mg on Day 1 of each cycle) together with a QD regimen of BMC128, followed by a Iong-term Nivolumab monotherapy. Prior to starting this combination treatment, patients will undergo: I. Native microbiota depletion stage - patients will be treated with oral Vancomycin 500mg in combination with Neomycin 1000mg, q6h for 72 hours. II. BMC128 monotherapy induction stage - One BMC128 capsule will be administered once daily QD for a period of 14 days.


Drug: - BMC128

A live bio-therapeutic product composed of 4 commensal bacterial strains, natural inhabitants of the human intestinal tract.

Drug: - Nivolumab

A human monoclonal antibody that blocks programmed-death-1 (PD-1). It is a type of immunotherapy and works as a checkpoint inhibitor, blocking a signal that prevents activation of T cells from attacking the cancer.
