Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a 2-arm, noncomparative phase 2 trial designed to evaluate treatment outcomes with or without the addition of ciprofloxacin, metronidazole, and aspirin to first-line chemotherapy for patients with stage IV colorectal cancer (CRC).

Official Title

Pilot Study Evaluating Microbiome Modulation Therapy (MBMT) With Ciprofloxacin, Metronidazole, and Aspirin in Addition to Standard of Care Chemotherapy in Patients Undergoing First-Line Therapy for Metastatic Colorectal Cancer

Inclusion Criteria	Exclusion Criteria
* Diagnosis of stage IV colorectal cancer * Measurable disease by Response evaluation criteria in solid tumors (RECIST) 1.1 criteria * Planned first-line treatment with a 5FU-based doublet chemotherapy regimen for colon cancer, specifics of the regimen at the discretion of the treating physician Note: Patients who have received adjuvant therapy \>6 months prior are eligible * Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-2 * Absolute neutrophil count (ANC) ≥1,500 cells/μL * Platelet count ≥100,000 cells/μL * Hemoglobin ≥8 g/dL Note: The use of transfusion or other intervention to achieve hemoglobin ≥8 g/dL is acceptable. * Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 × upper limit of normal (ULN) Note: Patients with documented liver metastases: AST and ALT ≤5 × ULN * Serum creatinine ≤1.5 x ULN or calculated creatinine clearance ≥40 mL/min using the Cockcroft-Gault equation: (140 - age) × body weight/plasma creatinine × 72 (× 0.85 if female) * Radiographically measurable disease by RECIST 1.1 * Nonpregnant and not actively breastfeeding * Sexually active patients of childbearing potential and their partners must agree to use medically acceptable form of contraception, per treating investigator, throughout the study Patients should continue to use medically acceptable methods of contraception after study treatment ends, following the guidance for their specific chemotherapy regimen.	* ongoing full dose anticoagulation Note: Patients on full dose anticoagulation may be approached to discuss study participation if lowering anticoagulation dose is feasible per the discretion of the treating investigator. Patients will be required to lower the anticoagulation dose by half 48 hours before beginning study drugs * Total colectomy * Diagnosed with Cockayne Syndrome * Using disulfiram, tizanidine, or theophylline and unable to stop taking these medications for the length of the microbiome modulation therapy * On methotrexate doses of 15 mg/week or more * History of allergic reaction to ciprofloxacin, metronidazole, or aspirin * Antibiotic use in the 30 days before chemotherapy start * Corrected QT interval (QTc) \>480 on baseline ECG * Clinically significant hematuria, hematemesis, or hemoptysis of \>0.5 teaspoon (2.5 mL) of red blood, or other history of significant bleeding (eg, pulmonary hemorrhage) within 12 weeks before first dose of microbiome modulation therapy (significance determined by treating investigator) * Diagnosed with a malabsorptive syndrome * Inability to swallow tablets
