Gelclair at Conditioning or After Oral Mucositis Diagnosed vs. Magic Mouth Wash in Stem Cell Transplant Recipients

Overview

Patients receiving high-dose chemotherapy/conditioning prior to stem cell transplantation (SCT) are at high risk for developing painful lesions in the oral cavity, known as oral mucositis (OM). In this high risk adult population, the study objectives are to investigate the efficacy and tolerability of Gelclair® (GEL; an FDA cleared medical device indicated for the management of painful oral lesions) and ideal timing of initiation of therapy (at the time of conditioning or after mild OM is diagnosed) for the management of oral mucositis (OM), relative to a commercially available compounded mouth wash (First® Mouthwash BLM "Magic Mouth Wash"; MMW) initiated after mild OM is diagnosed. The study may be adapted based on an interim analysis and recommendations of the interim data review committee.

Full Title of Study: “An Adaptive Design, Single-Blind, Randomized, Controlled Study Investigating Polyvinylpyrrolidone (PVP) and Sodium Hyaluronate-Containing Oral Gel (Gelclair®) in Comparison to Viscous Lidocaine, Diphenhydramine, and Aluminum-magnesium Hydroxide/Simethicone Antacid Suspension Mouthwash (“Magic Mouthwash”) for the Management of Oral Mucositis Associated With High Dose Chemotherapy and Methotrexate in Allogeneic Stem Cell Transplant Recipients”

Detailed Description

Adult patients at high risk for developing OM receiving one of the following myeloablative (MA) pre-transplant conditioning regimens prior to allogeneic transplant along with methotrexate (MTX) as part of graft vs. host disease (GVHD) prophylaxis meeting all other eligibility criteria will be enrolled: – FluBu based regimens: either fludarabine: 30 mg/m^2 x 4 days and busulfan 0.8 mg/kg IV q6h x 4 days; both given daily starting at day -4 OR fludarabine: 40 mg/m^2 and busulfan: 3.2 mg/kg both given daily on days -6 through -3. – Bu/Cy: busulfan, 0.8 mg/kg IV q6h x 4 days (-7 through -4); cyclophosphamide: 60 mg/kg IV once on days -3 and -2 – Cy/TBI: Cyclophosphamide, 60 mg/kg IV given twice between days -3 and -1 and TBI fractionated (generally over 3 days) for a total of 12Gy GVHD Prophylaxis: • Regimens including methotrexate (MTX; 15 mg/m^2 planned to be given on days 1, 3, 6 and 11); addition of other agents given along with MTX (e.g., tacrolimus, sirolimus) is acceptable. Duration of treatment: – Arm 1: GEL treatment a minimum of 4x/day initiated from 1st day of conditioning through OM resolution (G0), up to a maximum of 20d. – Arms 2 (GEL) and 3 (MMW): Treatment a minimum of 4x/day initiated when G1 or G2 OM diagnosed during observation period (through Day +14 relative to stem cell infusion) through OM resolution (G0), up to a maximum of 20d.

Interventions

  • Device: Gelclair
    • Polyvinylpyrrolidone (PVP) and Sodium Hyaluronate-Containing Oral Gel
  • Combination Product: First® Mouthwash BLM
    • Viscous Lidocaine, Diphenhydramine, and Aluminum-magnesium Hydroxide/Simethicone Antacid Suspension Mouthwash

Arms, Groups and Cohorts

  • Experimental: Arm 1 (Gelclair at time of conditioning)
    • All subjects in study Arm 1 will receive GEL starting on the first day of conditioning.
  • Active Comparator: Arm 2 (Gelclair when OM diagnosed)
    • Subjects in Arm 2 will be observed from initiation of conditioning to Day +14. If subjects develop G1 or G2 OM via WHO OM scale during this period, they will at that time be randomized to immediately receive GEL.
  • Active Comparator: Arm 3 (MMW when OM diagnosed)
    • Subjects in Arm 2 will be observed from initiation of conditioning to Day +14. If subjects develop G1 or G2 OM via WHO OM scale during this period, they will at that time be randomized to immediately receive MMW.
