Primary Peritoneal Cavity Cancer, Recurrent Ovarian Epithelial Cancer

Brief summary

Phase II trial to study the effectiveness of bortezomib in treating patients who have persistent or recurrent ovarian epithelial cancer or primary peritoneal cancer. Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for their growth.

Detailed description

PRIMARY OBJECTIVES: I. Determine the antitumor activity of bortezomib in patients with persistent or recurrent platinum-sensitive ovarian epithelial or primary peritoneal carcinoma. II. Determine the nature and degree of toxicity of this regimen in these patients. OUTLINE: This is a multicenter study. Patients receive bortezomib IV twice weekly for 2 weeks. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity. Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

Design outcomes

Primary

MeasureTime frameDescription
Tumor Response DurationFrom study entry, up to 5 yearsRECIST 1.0 defines complete response as the disappearance of all target lesions and non-target lesions and no evidence of new lesions documented by two disease assessments at least 4 weeks apart. Partial response is defined as at least a 30% decrease in the sum of longest dimensions (LD) of all target measurable lesions taking as reference the baseline sum of LD. There can be no unequivocal progression of non-target lesions and no new lesions. Documentation by two disease assessments at least 4 weeks apart is required. In the case where the ONLY target lesion is a solitary pelvic mass measured by physical exam, which is not radiographically measurable, a 50% decrease in the LD is required. These patients will have their response classified according to the definitions stated above. Complete and partial responses are included in the objective tumor response rate.
Frequency and Severity of Observed Adverse EventsUp to 5 years
Objective Partial/Complete Tumor Response Based on the Gynecologic Oncology Group (GOG) Response Evaluation Criteria in Solid Tumors (RECIST) CriteriaFrom study entry until disease progression/intolerable toxicity/study withdrawalNumber of participants who experienced an objective tumor response up to 5 years. Per RECIST version 1.0 criteria: each target lesion must be \>= 20 mm when measured by conventional techniques, including palpation, plain x-ray, CT, and MRI, or \>= 10 mm when measured by spiral CT. Complete Response is a disappearance of all target and non-target lesions. Partial Response is at least a 30% decrease in the sum of longest dimensions (LD) of all target measurable lesions, taking as reference the baseline sum of LD.

Secondary

MeasureTime frameDescription
Overall SurvivalFrom study entry, up to 5 years following disease progression
Progression-Free SurvivalFrom study entry up to 5 yearsProgression is defined according to RECIST v1.0 as at least a 20% increase in the sum of LD target lesions taking as reference the smallest sum LD recorded since study entry, the appearance of one or more new lesions, death due to disease without prior objective documentation of progression, global deterioration in health status attributable to the disease requiring a change in therapy without objective evidence of progression, or unequivocal progression of existing non-target lesions.

Recruitment details

Accrual was broken down into two cohorts. Cohort 1 enrolled 28 participants from 11/5/2001 through 1/6/2003. Cohort 2 enrolled 30 participants from 4/5/2004 through 9/6/2005.

Participants by arm

Cohort 1
Patients enrolled 11/5/2001 through 1/6/2003 receive bortezomib 1.5 mg/m2/dose IV twice weekly for 2 weeks (Days 1,4,8, and 11) followed by a 10day rest period (Days 12-21). At least 72 hours should elapse between consecutive doses.Courses repeat every 3 weeks (21 days) until disease progression or adverse effects prohibit further therapy.

Objective Partial/Complete Tumor Response Based on the Gynecologic Oncology Group (GOG) Response Evaluation Criteria in Solid Tumors (RECIST) Criteria

Number of participants who experienced an objective tumor response up to 5 years. Per RECIST version 1.0 criteria: each target lesion must be \>= 20 mm when measured by conventional techniques, including palpation, plain x-ray, CT, and MRI, or \>= 10 mm when measured by spiral CT. Complete Response is a disappearance of all target and non-target lesions. Partial Response is at least a 30% decrease in the sum of longest dimensions (LD) of all target measurable lesions, taking as reference the baseline sum of LD.

Time frame: From study entry until disease progression/intolerable toxicity/study withdrawal

Tumor Response Duration

RECIST 1.0 defines complete response as the disappearance of all target lesions and non-target lesions and no evidence of new lesions documented by two disease assessments at least 4 weeks apart. Partial response is defined as at least a 30% decrease in the sum of longest dimensions (LD) of all target measurable lesions taking as reference the baseline sum of LD. There can be no unequivocal progression of non-target lesions and no new lesions. Documentation by two disease assessments at least 4 weeks apart is required. In the case where the ONLY target lesion is a solitary pelvic mass measured by physical exam, which is not radiographically measurable, a 50% decrease in the LD is required. These patients will have their response classified according to the definitions stated above. Complete and partial responses are included in the objective tumor response rate.

Time frame: From study entry, up to 5 years

Progression-Free Survival

Progression is defined according to RECIST v1.0 as at least a 20% increase in the sum of LD target lesions taking as reference the smallest sum LD recorded since study entry, the appearance of one or more new lesions, death due to disease without prior objective documentation of progression, global deterioration in health status attributable to the disease requiring a change in therapy without objective evidence of progression, or unequivocal progression of existing non-target lesions.

Time frame: From study entry up to 5 years

Cohort 2 - Bortezomib (1.3 mg/m2)Progression-Free Survival1.4 months
