Study With IMC-A12 (Cixutumumab) in Patients Who Have Not Previously Been Treated With Chemotherapy With Metastatic Prostate Cancer

June 18, 2018 updated by: Eli Lilly and Company

Phase 2 Single Arm, Open-Label Study of IMC-A12 in Asymptomatic, Chemotherapy-Naïve Patients With Metastatic Androgen-Independent Prostate Cancer

This single arm, multicenter, open-label, Phase II study will enroll chemotherapy-naive participants with metastatic, histologically-confirmed adenocarcinoma of the prostate (stage M1 D2). Treatment will continue until there is evidence of disease progression, intolerable toxicity, or other withdrawal criteria are met. Non-surgically castrated participants must continue the use of luteinizing hormone-releasing hormone (LHRH) agonists during protocol treatment.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Thirty-one chemotherapy-naїve participants with asymptomatic metastatic androgen-independent prostate cancer will be enrolled and treated with intravenous (i.v.) IMC-A12 (Cixutumumab) at 10 milligrams per kilogram (mg/kg) administered over 1 hour every 2 weeks. An additional 10 participants will be enrolled and treated with IMC-A12 at a dose of 20 mg/kg every three weeks. Treatment will continue until evidence of disease progression or intolerable toxicity. Radiographic evaluation of response will be performed every 8 weeks for the participants treated with i.v. IMC-A12 at 20 mg/kg.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Composite Time to Disease Progression (cTTP) for Participants Treated With Cixutumumab
Time Frame: From first dose of study drug until progressive disease (Up to 49.2 months)
cTTP was the time from the first day of treatment to the earliest onset of 1 of the following: tumor progression by Response Evaluation Criteria In Solid Tumors [RECIST, version 1.0] criteria: unequivocal evidence of progression by bone scan, new skeletal events, symptomatic progression (for participants without measurable disease), or other clinical events attributable to prostate cancer that in the opinion of the investigator require major interventions. Participants without tumor progression at data cut-off were censored.
From first dose of study drug until progressive disease (Up to 49.2 months)
Area Under the Curve (AUC) of IMC-A12 Administered at a Dose of 20 mg/kg Every 3 Weeks
Time Frame: Up to 42 months (predose, 1, 168, 336 and 504 h postdose for Cycles 1 to 4; additionally 24, 72 or 96 h, 120 and 240 or 246 h postdose for Cycle 4; predose and 1 h post dose for Cycles 5 to 9)
Up to 42 months (predose, 1, 168, 336 and 504 h postdose for Cycles 1 to 4; additionally 24, 72 or 96 h, 120 and 240 or 246 h postdose for Cycle 4; predose and 1 h post dose for Cycles 5 to 9)
Maximum Concentration (Cmax) of IMC-A12 Administered at a Dose of 20 mg/kg Every 3 Weeks
Time Frame: Up to 42 months (predose, 1, 168, 336 and 504 h postdose for Cycles 1 to 4; additionally 24, 72 or 96 h, 120 and 240 or 246 h post dose for Cycle 4; predose and 1 h postdose for Cycles 5 to 9)
Up to 42 months (predose, 1, 168, 336 and 504 h postdose for Cycles 1 to 4; additionally 24, 72 or 96 h, 120 and 240 or 246 h post dose for Cycle 4; predose and 1 h postdose for Cycles 5 to 9)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants Experiencing Serious Adverse Events (SAEs) and Adverse Events (AEs)
Time Frame: From randomization up to 49.2 months (and 30 day follow-up)
Clinically significant events were defined as SAEs and other non-serious adverse events AEs. Participants who died due to progressive disease (PD), AEs while on treatment or died during the 30 day post-treatment are included. A summary of SAEs and other non-serious AEs, regardless of causality, is located in the Reported Adverse Events module.
From randomization up to 49.2 months (and 30 day follow-up)
Time to Radiographically Evident Disease Progression
Time Frame: From first dose of study drug until radiographic progression (up to 48.6 months)
This is the time between first dose and radiographic progression defined as either: progression of measurable or non measurable lesions using the RECIST v 1.0, evidence of progression by bone scan or new skeletal event including new pathologic bone fracture, new bone lesion requiring radiation or surgery, or spinal cord/nerve root compression. Participants without evidence of disease progression at the date of latest tumor or bone radiograph were censored.
From first dose of study drug until radiographic progression (up to 48.6 months)
Number of Participants With Complete Response (CR) or Partial Response (PR) (Tumor Response Rate)
Time Frame: From Randomization up to progressive disease (49.2 months)
Response was defined using RECIST v1.0 criteria: CR was defined as the disappearance of all target lesions and PR was defined as at least a 30% decrease in sum of longest diameter of target lesions
From Randomization up to progressive disease (49.2 months)
Percentage of Participants With Prostate Specific Antigen (PSA) Response Rate
Time Frame: From Randomization up to 6.21 months
Percentage of participants with a PSA decrease of at least 50% from baseline PSA provided the participant had a PSA value of at least 2 nanograms per milliliter (ng/ml) at baseline. Percentage calculated as: (number of participants with PSA response rate / total number of participants) *100.
From Randomization up to 6.21 months
Progression-Free Survival (PFS) Rate at 6 Months
Time Frame: From randomization up to 48.6 months
PFS rate was the proportion of participants who had stable disease (SD), PR, or CR and were alive at 6 months after receiving their first dose of study medication. Response was defined using RECIST v1.0 criteria: CR was defined as the disappearance of all target lesions, PR was defined as at least a 30% decrease in sum of longest diameter of target lesions, and SD was defined as shrinkage or increase in tumor size that did not meet the above criteria. For participants not known to have died as of the data cut-off date and who did not have progressive disease, PFS was censored at the date of last visit with adequate assessment. For participants who received subsequent anticancer therapy prior to disease progression or death, PFS was censored at the date of last visit with adequate assessment prior to the initiation of post-discontinuation anticancer therapy. Percentage of participants = (Number of participants with PFS at 6 months / total number of participants analyzed) *100.
From randomization up to 48.6 months
Area Under the Curve (AUC) of IMC-A12 Administered at a Dose of 10 mg/kg Every 2 Weeks
Time Frame: Up to 42 months (predose and 1 h postdose for Cycles 1, 5, 9, 13, 17 and 21; additionally immediately following dosing, 168 and 336 h postdose for Cycle 1 only)
