A Study of IMC-1121B (Ramucirumab) With or Without Dacarbazine in Metastatic Malignant Melanoma

Eli Lilly and Company106 enrolled

Overview

The primary objective of this study is to determine the progression-free survival (PFS) of participants with previously untreated metastatic malignant melanoma when treated with IMC-1121B (ramucirumab) alone or in combination with dacarbazine.

The purpose of this study is to determine the antitumor activity and safety profile of IMC-1121B (ramucirumab) when used alone or in combination with dacarbazine in participants with metastatic melanoma who have not received prior chemotherapy for this disease.

Outcomes

Primary Outcomes

Progression Free Survival (PFS)

PFS was defined as the time from the first day of therapy to the first evidence of disease progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST v1.0) or death from any cause. Progressive disease (PD) was defined as at least a 20% increase in the sum of the longest diameter (LD) of the target lesions, taking as reference the smallest sum LD recorded since the treatment started in comparison with the measurement of the nadir or the appearance of 1 or more new lesions. In addition, unequivocal progression of existing non-target lesions was considered PD. New or existing pleural effusion/ascites required cytological confirmation for PD according to the protocol. Participants who did not progress and who were alive or did not have documented progression or missed ≥2 visits, or had no post baseline assessment were censored at the day of their last tumor assessment.

Time frame: Baseline up to 36 months

Secondary Outcomes

Number of Participants With Adverse Events (AE)

The number of participants who experienced any IMC-1121B (ramucirumab \[RAM\]) treatment-related and treatment emergent AE (TEAE), treatment-related TEAE of Grade ≥3, treatment-related TE serious AEs (SAEs), treatment-related TEAE resulting in death (Grade 5 AE) and any TEAEs resulting in death. A summary of SAEs and all other non-serious AEs, regardless of causality, is located in the Reported Adverse Events module.

Time frame: Baseline up to 40 months

Percentage of Participants With Complete Response (CR) or Partial Response (PR) [Overall Response Rate (ORR)]

The ORR was defined as the percentage of all randomized participants with the best overall response of PR or CR using Response Evaluation Criteria in Solid Tumors (RECIST v1.0). CR was defined as the disappearance of all target and non-target lesions. PR was defined as at least a 30% decrease in sum of longest diameter of target lesions. CR and PR had to be confirmed by repeat assessments and performed no fewer than 4 weeks after the criteria for response were first met.

Time frame: Cycle 1 Day 1 (of 21-day cycle) up to 17.1 months

Duration of Response

The duration of overall response was defined as the time from first assessment of complete response (CR) or partial response (PR) to the first date of progressive disease (PD) using Response Evaluation Criteria in Solid Tumors (RECIST v1.0), initiation of other or additional antitumor therapy, or death from any cause. CR was defined as the disappearance of all target lesions. PR was defined as having at least a 30% decrease in sum of longest diameter of target lesions. CR and PR had to be confirmed by repeat assessments and performed no fewer than 4 weeks after the criteria for response were first met. PD was defined as at least 20% increase in sum of longest diameter of target lesions. Participants who did not relapse were censored at the day of their last objective tumor assessment.

Time frame: Cycle 1 Day 1 (of 21-day cycle) up to 17.1 months

Percentage of Participants With Stable Disease (SD) or Better (Disease Control Rate) at 6 Weeks

Disease Control Rate (DCR) was defined as complete response (CR) plus partial response (PR) plus SD using Response Evaluation Criteria in Solid Tumors (RECIST v1.0). CR was defined as the disappearance of all target and non-target lesions and the normalization of non-target lesion tumor marker levels. PR was defined as at least a 30% decrease from baseline in sum of longest diameter of target lesions. CR and PR had to be confirmed by repeat assessments and performed no fewer than 4 weeks after the criteria for response were first met. SD was defined as: neither sufficient increase to qualify for progressive disease (PD) nor sufficient shrinkage to qualify for PR, taking as reference the smallest sum of the longest diameters recorded since treatment began. PD was defined as at least 20% increase in sum of longest diameter of target lesions.

Time frame: 6 weeks (2 cycles of treatment)

Percentage of Participants With Stable Disease (SD) or Better (Disease Control Rate) at 12 Weeks

Disease Control Rate (DCR) was defined as complete response (CR) plus partial response (PR) plus SD using Response Evaluation Criteria in Solid Tumors (RECIST v1.0). CR was defined as the disappearance of all target and non-target lesions and the normalization of non-target lesion tumor marker levels. PR was defined as at least a 30% decrease from baseline in sum of longest diameter of target lesions. CR and PR had to be confirmed by repeat assessments and performed no fewer than 4 weeks after the criteria for response were first met. Stable Disease (SD) was defined as: neither sufficient increase to qualify for progressive disease (PD) nor sufficient shrinkage to qualify for PR, taking as reference the smallest sum of the longest diameters recorded since treatment began. PD was defined as at least 20% increase in sum of longest diameter of target lesions.

Time frame: 12 weeks (4 cycles of treatment)

Percentage of Participants With Complete Response (CR) or Partial Response (PR) (Response Rate) at 12 Weeks

Response rate was defined as a CR or a PR using Response Evaluation Criteria in Solid Tumors (RECIST v1.0). CR was defined as the disappearance of all target and non-target lesions and the normalization of non-target lesion tumor marker levels. PR was defined as at least a 30% decrease from baseline in sum of longest diameter of target lesions. CR and PR had to be confirmed by repeat assessments and performed no fewer than 4 weeks after the criteria for response were first met.
