Brief Summary

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.

Detailed Description

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

Conditions

Non-small Cell Lung Cancer; Melanoma; Renal Cell Carcinoma

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

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.

Group Type: EXPERIMENTAL

BMC128

Intervention Type: DRUG

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

Nivolumab

Intervention Type: DRUG

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.

Eligibility Criteria

Inclusion Criteria

1. Capable of providing signed informed consent to participate in the study, and to comply with the requirements and restrictions listed in the protocol.

2. ≥18 years of age at time of informed consent

3. Histologically or cytologically confirmed metastatic or locally advanced unresectable clear cell renal cell carcinoma (ccRCC), cutaneous melanoma, or EGFR/ ALK wildtype adenocarcinoma-type non-small cell lung carcinoma (NSCLC).

4. At least one measurable lesion per RECIST v 1.1 criteria

5. Subjects must have progressed on treatment with a PD-1/PD-L1 inhibitor administered either as monotherapy, or in combination with other checkpoint inhibitors or other therapies. PD-1/PDL-1 inhibitor treatment progression is defined by meeting all of the following criteria:

1. Has received at least 2 doses of a PD-1/PD-L1 inhibitor.

2. Has demonstrated disease progression after PD-1/PD-L1 therapy as defined by RECIST v1.1, iRECIST or irRECIST. The initial evidence of disease progression (PD) is to be confirmed by a second assessment no less than four weeks from the date of the first documented PD, in the absence of rapid clinical progression.

3. Progressive disease has been documented within 12 weeks from the last dose of a PD-1/PD-L1 inhibitor.

6. Subjects must have had prior response to anti-PD1/PDL-1 as single agent or in combination with other cancer therapies, defined as at least stable disease per iRECIST, as assessed by 2 consecutive imaging ≥ 4 weeks apart, with the first one performed no earlier than 9 weeks from initiation of anti PD1/PDL-1 treatment.

7. Subjects must demonstrate adequate organ functions at Screening:

1. Absolute neutrophil count ≥1500/μL, platelet count ≥100,000/μL; hemoglobin ≥9.0 g/dL Note: Patients must not have received any growth factors or blood transfusions within 28 days prior to the Screening hematologic laboratory tests

2. Total bilirubin <1.5 × the upper limit of normal (ULN) (with the exception of patients diagnosed with Gilbert syndrome), Alanine aminotransferase or aspartate aminotransferase <1.5 × ULN

3. Creatinine ≤ 1.5 ULN and/or estimated glomerular filtration rate ≥ 60

4. Albumin >30 g/L (3.0 g/dL)

8. Eastern Cooperative Oncology Group (ECOG) performance status 0-1

9. Female subjects of childbearing potential should have a negative urine pregnancy test within 72 hours prior to enrolment (enrolment = start of depletion phase). If urine pregnancy results cannot be confirmed as negative, a SERUM β-HCG pregnancy test is required. Subjects of childbearing potential are those who have not been surgically sterilized or those age < 60 y who have not been free from menses for ≥2 years.

10. Female subjects of childbearing potential must be willing to use 2 methods of birth control starting from the start of the induction phase or be surgically sterile, or abstain from heterosexual activity throughout the course of the study and 120 days after the last dose of study medication

11. Male subjects with female partners of childbearing potential should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.

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.
