Prospective Study of Palonosetron in Radiation Induced Nausea and Vomiting (RINV)

Overview

This phase II study will investigate the use of palonosetron in the efficacy of prophylaxis or rescue of single or multiple fraction radiation induced nausea and vomiting. This prospective study employs a parallel arm design, allowing for inclusion of patients with pre-existing nausea and vomiting versus no current nausea or vomiting. Eligible patients receiving radiotherapy known to have a low or moderate emetogenic risk will receive every other day dosing of 0.5 mg palonosetron for the length of treatment. Nausea, vomiting, use of rescue medication, and impact on quality of life will be monitored during and after radiation treatment completion.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Non-Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Prevention
    • Masking: None (Open Label)
  • Study Primary Completion Date: August 7, 2017

Clinical Trial Outcome Measures

Primary Measures

  • Efficacy for prevention of nausea and vomiting events as measured by a daily diary
    • Time Frame: Day 0 to Day 10 post-radiation
    • Primary outcome is to determine the efficacy of palonosetron for the prevention of radiation-induced vomiting in patients undergoing low or moderate emetogenic radiation therapy. Daily diary collects events of nausea and/or vomiting, and corresponding severity.

Secondary Measures

  • Complete prophylaxis of nausea
    • Time Frame: Day 0 to Day 10 post-radiation
    • Proportion of patients achieving complete prophylaxis of nausea and not requiring the use of any, or supplemental rescue antiemetic medication during and in the 10 days following radiation therapy
  • Complete prophylaxis of vomiting
    • Time Frame: Day 0 to Day 10 post-radiation
    • Proportion of patients achieving complete prophylaxis of vomiting without requiring the use of any, or supplemental rescue antiemetic medication during and in the 10 days following radiation therapy
  • Partial control of nausea
    • Time Frame: Day 0 to Day 10 post-radiation
    • Proportion of patients achieving partial control of nausea during and in the 10 days following radiation therapy
  • Partial control of vomiting
    • Time Frame: Day 0 to Day 10 post-radiation
    • Proportion of patients achieving partial control of vomiting during and in the 10 days following radiation therapy
  • Time to use of rescue medication
    • Time Frame: Day 0 to Day 10 post-radiation
    • Median time from first fraction of radiation therapy to first use or increase in use of rescue medication
  • Time to nausea
    • Time Frame: Day 0 to Day 10 post-radiation
    • Median time from first fraction of radiation therapy to first episode or increase in episodes of nausea
  • Time to vomiting
    • Time Frame: Day 0 to Day 10 post-radiation
    • Median time from first fraction of radiation therapy to first episode or increase in episodes of vomiting
  • Quality of life
    • Time Frame: Baseline, during the 5th and 10th day of radiation (if applicable), and 3, 5, 7, and 10 days post radiation.
    • Quality of life as measured by the EORTC QLQ-C15-PAL and the FLIE.
  • Adverse effects
    • Time Frame: Day 0 to Day 10 post-radiation
    • The side effects of constipation and headache will be monitored throughout the study period graded according to the CTCAE criteria.
