简要总结
The primary objective of the study is to examine the efficacy of Ondissolve for the prevention/rescue of Acute and Delayed Phase radiation induced nausea and vomiting (RINV) in patients undergoing single or multiple fraction, emetogenic palliative radiation therapy for painful bone metastases. The study population will be 30 patients seen in the RRRP at the Sunnybrook Odette Cancer Centre receiving palliative radiation therapy considered emetogenic for bone metastases. Patients will take the study medication (Ondissolve 8 mg) twice on each day of radiation therapy, at least one hour prior to treatment and repeat approximately 6-8 hours later the same day. Patients undergoing multiple fraction radiation therapy will take Ondissolve on weekends or holidays in between treatment. Secondary objectives include to evaluate key secondary endpoints related to RINV, and to investigate the ease and length of administration of protocol medicine. We hypothesize that Ondissolve will be effective in the prophylaxis of RINV, and the ease of use and administration will provide an appropriate delivery method for those unable to tolerate the oral form of ondansetron.

研究组 & 干预措施
Secondary prophylaxis
Patients already experiencing mild nausea/vomiting within 24 hours before radiotherapy. Intervention is 8mg of ondansetron (Ondissolve) on the day of radiation treatment at least 1 hour prior to treatment and repeated approx. 608 hours later in the day (bid). For patients who are treated with 20Gy/5 fractions, or 30Gy/10 fractions, they will take ondansetron twice (bid) on each day of treatment, at least 1 hour prior to treatment, and also on weekends or holidays in between treatment.
干预措施: Ondansetron (Drug)
Primary prophylaxis
Patients experiencing no nausea and vomiting 24 hours before commencement of radiotherapy. Intervention is 8mg of ondansetron (Ondissolve) on the day of radiation treatment at least 1 hour prior to treatment and repeated approx. 608 hours later in the day (bid). For patients who are treated with 20Gy/5 fractions, or 30Gy/10 fractions, they will take ondansetron twice (bid) on each day of treatment, at least 1 hour prior to treatment, and also on weekends or holidays in between treatment.
干预措施: Ondansetron (Drug)

时间窗: Day 0 - Day 10
The primary objectives are to examine the efficacy for the prevention/rescue of Acute and Delayed Phase radiation-induced nausea and vomiting (RINV) in patients undergoing single or multiple fraction, emetogenic palliative radiation therapy for painful bone metastases. Complete control: No increase in emetic episodes or increase in use of rescue medication (for secondary prophylaxis) following radiation treatment, compared to the number of incidences at baseline. Partial control: Increase of 2 or fewer emetic episodes from baseline and no use of rescue antiemetic medication during or after radiotherapy. Uncontrolled: Increase of three or more emetic episodes or use of antiemetic rescue medication.
