MeasureTime frameDescription
Percentage of Participants Who Achieved a Complete Response in the Overall Phase (0-120 Hours) Following Initiation of the First Cycle of an Oxaliplatin Based Moderately Emetogenic Chemotherapy (MEC) Regimen0 to 120 hours in the first cycle of chemotherapyComplete response was defined as no vomiting, no retching and no use of anti-emetic rescue medication. Participants who vomited or retched or received rescue medication in the acute phase (0- 24 hours) following administration of oxaliplatin were also considered as complete response failures in the subsequent delayed (24-120 hour) time period, irrespective of actual response in the delayed phase. However, participants who vomited or retched or received rescue medication in the delayed (24-120 hours) phase were not considered as failures in the acute (0-24 hours) phase. The overall phase began at the start of the administration of the oxaliplatin infusion. Percentage of participants who achieved a complete response in the overall phase (0-120 hours) are presented.

Secondary

MeasureTime frameDescription
Percentage of Participants Who Achieved a Complete Response in the Delayed Phase of Cycle 124 to 120 hours (delayed phase) in the first cycle of chemotherapyComplete response was defined as no vomiting, no retching and no use of anti-emetic rescue medication. Participants who vomited or retched or received rescue medication in the acute phase (0- 24 hours) following administration of oxaliplatin were also considered as complete response failures in the subsequent delayed (24-120 hour) time period, irrespective of actual response in the delayed phase. However, participants who vomited or retched or received rescue medication in the delayed (24-120 hours) phase were not considered as failures in the acute (0-24 hours) phase. Percentage of participants who achieved a complete response in the delayed phase of Cycle 1 are presented.
Percentage of Participants Who Achieved a Complete Response in the Overall Phase of Cycle 20 to 120 hours in the second cycle of chemotherapyComplete response was defined as no vomiting, no retching and no use of anti-emetic rescue medication. Participants who vomited or retched or received rescue medication in the acute phase (0- 24 hours) following administration of oxaliplatin were also considered as complete response failures in the subsequent delayed (24-120 hour) time period, irrespective of actual response in the delayed phase. However, participants who vomited or retched or received rescue medication in the delayed (24-120 hours) phase were not considered as failures in the acute (0-24 hours) phase. The overall phase began at the start of the administration of the oxaliplatin infusion. Percentage of participants who achieved a complete response in the overall phase of Cycle 2 are presented.
Maximum Nausea Score, Assessed by a Visual Analogue Scale (VAS)0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyVAS was used to assess severity of nausea. The participants rated the severity of nausea by marking a line on a 100 millimeter (mm) (0 to 100 mm) long scale. A line placed on the extreme left, that is 0 mm indicated no nausea and extreme right that is 100 mm indicated nausea as bad as it can be. This scale has no subscales. The participant perception of their symptoms was measured using the VAS.
Percentage of Participants Who Received Rescue Medication0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyAnti-emetic rescue medication was defined as medication that was administered specifically for the treatment of nausea and/or emesis during Days 1-6 of each cycle. The choice of rescue anti-emetic medication was left to the discretion of the investigator. Participants who required antiemetic rescue medication(s) during the 120-hour assessment period were considered treatment failures for that cycle. Percentage of participants who received rescue medication are presented.
Percentage of Participants Who Vomited and/or Retched0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyVomiting was defined as the forceful expulsion of gastrointestinal contents through the mouth or nose. Retching was defined as the labored, spasmodic, rhythmic contraction of the respiratory and abdominal muscles in an attempt to vomit, that is not productive of gastrointestinal contents (also known as dry heaves). If a participant took rescue medication but there was no evidence of vomiting or retching, then the participant was considered as not having vomited. Percentage of participants who vomited and/or retched during the first 120 hours of the first cycle of chemotherapy are presented.
Percentage of Participants Who Reported Significant Nausea, Defined as a Maximum Score >= 25 mm on the VAS0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyVAS was used to assess severity of nausea. The participants rated the severity of nausea by marking a line on a 100 mm (0 to 100 mm) long scale. A line placed on the extreme left, that is 0 mm indicated no nausea and extreme right that is 100 mm indicated nausea as bad as it can be. This scale has no subscales. The participant perception of their symptoms was measured using the VAS. Percentage of participants who reported significant nausea, defined as a maximum score \>= 25 mm on the VAS are presented.
Percentage of Participants Who Reported Nausea, Defined as a Maximum Score of >= 5 mm on the VAS0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyVAS was used to assess severity of nausea. The participants rated the severity of nausea by marking a line on a 100 mm (0 to 100 mm) long scale. A line placed on the extreme left, that is 0 mm indicated no nausea and extreme right that is 100 mm indicated nausea as bad as it can be. This scale has no subscales. The participant perception of their symptoms was measured using the VAS. Percentage of participants who reported nausea, defined as a maximum score of \>= 5 mm on the VAS are presented.
Percentage of Participants Who Achieved Complete Protection Defined as Complete Responders With no Significant Nausea0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyComplete protection was defined as no vomiting/retching, no use of rescue medication and no significant nausea. Percentage of participants who achieved complete protection or complete responders with no significant nausea are presented.
Percentage of Participants Who Achieved Total Control, Defined as Complete Responders Who Had no Nausea0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyTotal control was defined as no vomiting/retching, no use of rescue medication and no nausea. Percentage of participants who achieved total control or complete responders with no nausea are presented.
Percentage of Participants Whose Daily Life Activities Were Impacted in the Overall Phase of Cycle 1, Assessed by Functional Living Index-Emesis (FLIE) Questionnaire0 to 120 hours in the first cycle of chemotherapyFLIE questionnaire specifically addresses the impact of nausea and vomiting on daily activities (physical, social and emotional function, ability to enjoy meals). It consists of 18 items with questions divided into two domains: Nausea (questions 1-9) and Vomiting (questions 10-18). Each item is scored on a VAS with 7 hatch marks. The scale is anchored at 1 (Not at all) and 7 (A great deal). For questions 1,2,4,5,7,8-10,12-14,16 and 17 the final score was calculated by subtracting the initial score from 100 for questions 3,6,11,15 and 18 the final score was the one provided in the dataset. The score for the nausea domain: (\[sum of nausea item scores\] ÷ \[Number of items answered\] x 9) and for vomiting domain: (\[sum of vomiting item scores\] ÷ \[Number of items answered\] x 9). The total score was the sum of the nausea and vomiting domain scores. Higher scores indicate less impairment on daily life as a result of nausea or vomiting.
Severity of Nausea in the Overall, Acute, and Delayed Phases of Cycle 1 Assessed by a Categorical Scale0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapyParticipants were asked to rate the level of nausea he/she experienced over the previous (24 hours for a period of 120 hours following the administration of MEC), by placing a vertical mark on a VAS. The severity of nausea and was calculated by using a 0 - 100 VAS where 0 = No Nausea and 100 = Nausea as bad as it can be. The categorical scale assessed the participants severity of his/her nausea using the following: mild: Queasiness/upset stomach that is manageable and minimally (if at all) affects daily activities, moderate: increased queasiness, sometimes with the feeling of having to vomit/throw up (but not vomiting), that has significant negative effect on the daily activities (for example, being unable to work, eat and drink, prepare food, care for children or others) and severe: feeling sick and vomiting or feeling like you are going to vomit, and unable to perform most daily activities. Higher scores indicated worst outcome.
Percentage of Participants Who Achieved a Complete Response in the Acute Phase of Cycle 10 to 24 hours in the first cycle of chemotherapyComplete response was defined as no vomiting, no retching and no use of anti-emetic rescue medication. Participants who vomited or retched or received rescue medication in the acute phase (0- 24 hours) following administration of oxaliplatin were also considered as complete response failures in the subsequent delayed (24-120 hour) time period, irrespective of actual response in the delayed phase. However, participants who vomited or retched or received rescue medication in the delayed (24-120 hours) phase were not considered as failures in the acute (0-24 hours) phase. Percentage of participants who achieved a complete response in the acute phase of Cycle 1 are presented.

Evaluation of Vital Signs: Mean Diastolic Blood Pressure (DBP) and Systolic Blood Pressure (SBP)Up to End of Cycle for 6 cycles, an average of 24 days per cycleVital signs assessment included DBP and SBP. SBP and DBP were recorded at Screening, on Day 1 of each cycle immediately before start of the investigational product infusion, at the completion of the infusion, and immediately after the end of the oxaliplatin infusion, then again at each end of cycle visit. Mean SBP and DBP are presented.
Evaluation of Vital Signs: Mean Heart RateUp to End of Cycle for 6 cycles, an average of 24 days per cycleVital sign included heart rate which was recorded at Screening, on Day 1 of each cycle immediately before start of the investigational product infusion, at the completion of the infusion, and immediately after the end of the oxaliplatin infusion, then again at each end of cycle visit. Mean heart rate is presented.
Time to First Anti-emetic Rescue Medication0 to 120 hours in the first cycle of chemotherapyTime to first rescue medication was defined as the length of time from initiation of oxaliplatin till the first reported use of a rescue medication. Participants withdrawing prematurely during the 120 hour assessment period without having received a rescue medication were assumed to have done so and the time of rescue medication was set to 0 hours. The first quartile for time to use of anti-emetic rescue medication was evaluated when 25th percentile of participants of MITT population reported use of anti-emetic rescue medication. Similarly, median and 75th percentile of participants of MITT population was planned to be reported. If, less than 25th percentile of participants reported use of anti-emetic rescue medication at the end of the 120 hour time period, then the observation was censored for the purpose of this analysis and in such case the data was planned to be reported as not evaluable (NA).
Time to First Emetic Event0 to 120 hours in the first cycle of chemotherapyTime to first emetic event was defined as the length of time from initiation of oxaliplatin until the time of first emetic event. Participants withdrawing prematurely from the study without having experienced an emetic event were assumed to have done so and the time of emetic event was set to 0 hours. The first quartile for time to emetic event was evaluated when 25th percentile of participants of MITT population reported emetic event. Similarly, median and 75th percentile of participants of MITT population was planned to be reported. If, less than 25th percentile of participants reported emetic event at the end of the 120 hour time period, then the observation was censored for the purpose of this analysis and in such case the data was planned to be reported as not evaluable (NA).

Primary

Percentage of Participants Who Achieved a Complete Response in the Overall Phase (0-120 Hours) Following Initiation of the First Cycle of an Oxaliplatin Based Moderately Emetogenic Chemotherapy (MEC) Regimen

Complete response was defined as no vomiting, no retching and no use of anti-emetic rescue medication. Participants who vomited or retched or received rescue medication in the acute phase (0- 24 hours) following administration of oxaliplatin were also considered as complete response failures in the subsequent delayed (24-120 hour) time period, irrespective of actual response in the delayed phase. However, participants who vomited or retched or received rescue medication in the delayed (24-120 hours) phase were not considered as failures in the acute (0-24 hours) phase. The overall phase began at the start of the administration of the oxaliplatin infusion. Percentage of participants who achieved a complete response in the overall phase (0-120 hours) are presented.

Time frame: 0 to 120 hours in the first cycle of chemotherapy

Population: Modified Intent-to-Treat Population (mITT) comprised of all participants who were randomized, received any investigational product and had oxaliplatin administered.

Maximum Nausea Score, Assessed by a Visual Analogue Scale (VAS)

VAS was used to assess severity of nausea. The participants rated the severity of nausea by marking a line on a 100 millimeter (mm) (0 to 100 mm) long scale. A line placed on the extreme left, that is 0 mm indicated no nausea and extreme right that is 100 mm indicated nausea as bad as it can be. This scale has no subscales. The participant perception of their symptoms was measured using the VAS.

Time frame: 0 to 24 hours, 24 to 120 hours and 0 to 120 hours in the first cycle of chemotherapy

Percentage of Participants Whose Daily Life Activities Were Impacted in the Overall Phase of Cycle 1, Assessed by Functional Living Index-Emesis (FLIE) Questionnaire

FLIE questionnaire specifically addresses the impact of nausea and vomiting on daily activities (physical, social and emotional function, ability to enjoy meals). It consists of 18 items with questions divided into two domains: Nausea (questions 1-9) and Vomiting (questions 10-18). Each item is scored on a VAS with 7 hatch marks. The scale is anchored at 1 (Not at all) and 7 (A great deal). For questions 1,2,4,5,7,8-10,12-14,16 and 17 the final score was calculated by subtracting the initial score from 100 for questions 3,6,11,15 and 18 the final score was the one provided in the dataset. The score for the nausea domain: (\[sum of nausea item scores\] ÷ \[Number of items answered\] x 9) and for vomiting domain: (\[sum of vomiting item scores\] ÷ \[Number of items answered\] x 9). The total score was the sum of the nausea and vomiting domain scores. Higher scores indicate less impairment on daily life as a result of nausea or vomiting.

Vomiting was defined as the forceful expulsion of gastrointestinal contents through the mouth or nose. Retching was defined as the labored, spasmodic, rhythmic contraction of the respiratory and abdominal muscles in an attempt to vomit, that is not productive of gastrointestinal contents (also known as dry heaves). If a participant took rescue medication but there was no evidence of vomiting or retching, then the participant was considered as not having vomited.

Severity of Nausea in the Overall, Acute, and Delayed Phases of Cycle 1 Assessed by a Categorical Scale

Participants were asked to rate the level of nausea he/she experienced over the previous (24 hours for a period of 120 hours following the administration of MEC), by placing a vertical mark on a VAS. The severity of nausea and was calculated by using a 0 - 100 VAS where 0 = No Nausea and 100 = Nausea as bad as it can be. The categorical scale assessed the participants severity of his/her nausea using the following: mild: Queasiness/upset stomach that is manageable and minimally (if at all) affects daily activities, moderate: increased queasiness, sometimes with the feeling of having to vomit/throw up (but not vomiting), that has significant negative effect on the daily activities (for example, being unable to work, eat and drink, prepare food, care for children or others) and severe: feeling sick and vomiting or feeling like you are going to vomit, and unable to perform most daily activities. Higher scores indicated worst outcome.

Single-dose Pharmacokinetic (PK) Parameters: Area Under the Curve (AUC) 0 to Infinity (0-∞), AUC 0 to t (0-t) and AUC 0 to 24 Hours (0-24) for Casopitant; AUC (0-t) and AUC (0-24) for Metabolites GSK525060, GSK517142 and GSK631832

Blood samples were obtained during Cycle 1 at the following times relative to the investigational product administration: pre-dose, end of infusion, 0.5, 1, 3, 5, 8, 12, 16, and 24 hours after the end of infusion. A final PK sample was collected between 30 and 48 hours after the investigational product infusion had completed. The actual time each sample was collected was captured to the nearest minute in the electronic case report form (eCRF). Following unblinding, only those participants who had been randomized to receive casopitant were included in the PK analyses. AUC(0-∞), AUC(0-t), AUC(0-24) for casopitant and metabolites GSK525060, GSK517142 and GSK631832 are presented.

Time to First Anti-emetic Rescue Medication

Time to first rescue medication was defined as the length of time from initiation of oxaliplatin till the first reported use of a rescue medication. Participants withdrawing prematurely during the 120 hour assessment period without having received a rescue medication were assumed to have done so and the time of rescue medication was set to 0 hours. The first quartile for time to use of anti-emetic rescue medication was evaluated when 25th percentile of participants of MITT population reported use of anti-emetic rescue medication. Similarly, median and 75th percentile of participants of MITT population was planned to be reported. If, less than 25th percentile of participants reported use of anti-emetic rescue medication at the end of the 120 hour time period, then the observation was censored for the purpose of this analysis and in such case the data was planned to be reported as not evaluable (NA).

Time frame: 0 to 120 hours in the first cycle of chemotherapy

Time to First Emetic Event

Time to first emetic event was defined as the length of time from initiation of oxaliplatin until the time of first emetic event. Participants withdrawing prematurely from the study without having experienced an emetic event were assumed to have done so and the time of emetic event was set to 0 hours. The first quartile for time to emetic event was evaluated when 25th percentile of participants of MITT population reported emetic event. Similarly, median and 75th percentile of participants of MITT population was planned to be reported. If, less than 25th percentile of participants reported emetic event at the end of the 120 hour time period, then the observation was censored for the purpose of this analysis and in such case the data was planned to be reported as not evaluable (NA).
