title: Triple drug combination in the prevention of nausea and vomiting following busulfan plus cyclophosphamide chemotherapy before allogeneic hematopoietic stem cell transplantation.
abstract: OBJECTIVE
  A clinical study of triple drug combination (aprepitant+palonosetron+ dexamethasone) was carried out to evaluate its efficacy in preventing both acute and delayed emesis after high-dose chemotherapy (HDC) with busulphan+cyclophosphamide (BuCy) before hematopoietic stem cell transplantation (HSCT).
  
  
  METHODS
  The study enrolled 60 patients suffering from various hematological malignancies: 20 in the triple drug antiemetic group and 20 in each of two historical control groups that received dexamethasone plus either ondansetron or palonosetron. The groups were comparable for statistical analysis. The observation period started with the initiation of chemotherapy (0 h) and continued for 24 h after its completion for the acute phase, and during 5 days after finishing chemotherapy for the delayed phase. The response rate of the study drugs was evaluated by a 4-grade scale based on the condition of nausea and vomiting: highly, moderately or slightly effective and not effective.
  
  
  RESULTS
  Patients treated with the triple drug combination had significantly higher response rates than those receiving palonosetron or ondansetron (+ dexamethasone) during both the acute and delayed phases: highly effective in early + late phases: 55 vs. 30 vs. 20%; highly effective in early phase: 70 vs. 30 vs. 20%; highly effective in late phase: 55 vs. 55 vs. 30%; highly + moderately effective in early phase: 75 vs. 32 vs. 25%; highly + moderately effective in late phase: 85 vs. 60 vs. 40% for triple drug combination, palonosetron + dexamethasone and ondansetron + dexamethasone, respectively.
  
  
  CONCLUSIONS
  This triple drug combination was more effective than ondansetron or palonosetron (+ dexamethasone) in preventing acute (especially), and delayed nausea and vomiting following BuCy chemotherapy before HSCT.
