Clinical Trial: A Study Of Sunitinib Compared To Placebo For Patients With Advanced Pancreatic Islet Cell Tumors

Study Status: Terminated
Recruit Status: Terminated
Study Type: Interventional

Official Title: A Phase III Randomized, Double-Blind Study Of Sunitinib (SU011248, SUTENT) Versus Placebo In Patients With Progressive Advanced/Metastatic Well-Differentiated Pancreatic Islet Ce

Brief Summary:

This study randomized patients with advanced pancreatic islet cell tumors to receive either sunitinib or placebo. Patients who were randomized to sunitinib received 37.5 mg of sunitinib daily, those randomized to placebo received a tablet that looked similar but had no active drug. Neither the patient or the doctor knew whether the patient was receiving sunitinib or placebo. Patients were followed to determine the status and size of their tumors, survival, quality of life and safety of the drug.

The study was designed to detect a 50% improvement in median PFS[Progression Free Survival] with 90% power and was to enroll 340 subjects. An interim analysis was planned when 130 events had occurred, and the final analysis was to be conducted when 260 events had occurred.

Study A6181111 was stopped early during the enrollment period because of a clear and clinically meaningful improvement in efficacy for the sunitinib treatment arm as recommended by the DMC [Data Monitoring Committee]. The actual number of subjects enrolled was 171 and the actual number of PFS events recorded was 81 PFS events. The decision to terminate the study was not based on safety concerns related to sunitinib administration.

Current Primary Outcome: Progression Free Survival (PFS) [ Time Frame: From time of randomization through Day 1 of Week 5, Week 9, and then every 8 weeks thereafter until disease progression or death ]

Time from randomization to first progression of disease (PD) or death for any reason in the absence of documented PD. PFS was calculated as (first event date minus first randomization date +1) divided by 30.4.


Original Primary Outcome: Progression free survival

Current Secondary Outcome:

  • Number of Subjects With Objective Response [ Time Frame: From time of randomization through Day 1 of Week 5, 9, and every 8 weeks thereafter ]
    Objective response = subjects with confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) for at least 4 weeks, confirmed by repeat tumor assessments. A CR was defined as the disappearance of all target lesions. A PR was defined as a > = 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.
  • Duration of Response (DR) [ Time Frame: From start of treatment through Day 1 of Week 5, 9, and every 8 weeks thereafter until disease progression or death due to any cause ]
    Time in months from the first documentation of objective tumor response to objective tumor progression or death due to any cause. DR was calculated as (the date of the first documentation of objective tumor progression or death due to any cause minus the date of the first CR or PR that was subsequently confirmed plus 1) divided by 30.4.
  • Time-to-Tumor Response (TTR) [ Time Frame: From time of randomization through Day 1 of Week 5, 9, and every 8 weeks thereafter ]
    Time from randomization to the first documentation of objective tumor response (CR or PR) that was subsequently confirmed.
  • Overall Survival (OS) [ Time Frame: From start of study treatment up to 22 months ]
    Time in months from time of randomization to date of death due to any cause. The median number of months is provided; however, the study was terminated early. OS data was not mature by the time of analysis. Median OS time cannot be accurately estimated by Kaplan-Meier method for either treatment arm.
  • European Organization for Research and Treatment of Cancer Quality of LifeQuestionnaire (EORTC QLQ-C30) - Global Quality of Life (QoL) Subscale [ Time Frame: Day 1 and every 4 weeks thereafter (Day 1 of each 4-week cycle) and at end of treatment/withdrawal ]
    EORTC QLQ-C30 scales: global health/QoL, functional domains (physical, role, cognitive, emotional, social), and symptom scales/items (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea). Recall period: past week; response range: not at all to very much, global/QOL range: very poor to excellent. Scale score range: 0 to 100. Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.
  • EORTC QLQ-C30 - Cognitive Functioning Subscale [ Time Frame: Day 1 and every 4 weeks thereafter (Day 1 of each 4-week cycle) and at end of treatment/withdrawal ]
    EORTC QLQ-C30 scales: global health/QoL, functional domains (physical, role, cognitive, emotional, social), and symptom scales/items (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea). Recall period: past week; response range: not at all to very much, global/QOL range: very poor to excellent. Scale score range: 0 to 100. Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.
  • EORTC QLQ-C30 - Emotional Functioning Subscale [ Time Frame: Day 1 and every 4 weeks thereafter (Day 1 of each 4-week cycle) and at end of treatment/withdrawal ]
    EORTC QLQ-C30 scales: global health/QoL, functional domains (physical, role, cognitive, emotional, social), and symptom scales/items (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea). Recall period: past week; response range: not at all to very much, global/QOL range: very poor to excellent. Scale score range: 0 to 100. Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.
  • EORTC QLQ-C30 - Physical Functioning Subscale [ Time Frame: Day 1 and every 4 weeks thereafter (Day 1 of each 4-week cycle) and at end of treatment/withdrawal ]
    EORTC QLQ-C30 scales: global health/QoL, functional domains (physical, role, cognitive, emotional, social), and symptom scales/items (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea). Recall period: past week; response range: not at all to very much, global/QOL range: very poor to excellent. Scale score range: 0 to 100. Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.
  • EORTC QLQ-C30 - Role Functioning Subscale [ Time Frame: Day 1 and every 4 weeks thereafter (Day 1 of each 4-week cycle) and at end of treatment/withdrawal ]
    EORTC QLQ-C30 scales: global health/QoL, functional domains (physical, role, cognitive, emotional, social), and symptom scales/items (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea). Recall period: past week; response range: not at all to very much, global/QOL range: very poor to excellent. Scale score range: 0 to 100. Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.
