Arms of the Study
Arm 1
Arm 2

Experimental
Arm A: Standard Anti-emetic regimen
Arm B: Dexamethasone, Ondansetron, Aprepitant
The standard anti-emetic arm: In this arm the treating medical oncologist will determine the choice of anti-emetic regimen that they perceive the patient would require and prescribe it. The treating physician will be blinded to result of the personalized composite emesis score. The physician may or may not choose to prescribe an NK-1 inhibitor as the study will not predetermine the type of anti-emetics used. In the event that the patient experienced chemo induced nausea and vomiting (CINV), modifications to the initial anti emetic regimen would be left to the treating physician.
The emesis risk model arm: Prior to the start of intravenous chemotherapy an emesis risk score will be calculated for both acute and delayed emesis. The anti-emetic prophylaxis treatment will follow the emesis risk score. Whereby either an acute emesis score of ≥7 and/or a delayed emesis score of >16 will be considered high-risk. The anti-emetics will be prescribed reflecting this risk for pre-chemotherapy, 8 hrs post chemotherapy and day 2-3 post chemotherapy. Dexamethasone, Ondansetron and Aprepitant will be given in different combination and doses depending on what score the participant receives based on their responses to the diary. For subsequent cycle the anti-emetic score will be re-calculated prior to each cycle and the choice of anti-emetics adjusted if necessary.
