Phase IV Panitumumab Study in Indian Subjects With Metastatic Colorectal Cancer

December 13, 2019 updated by: Dr. Reddy's Laboratories Limited

An Open Label, Multicenter, Non-Comparative, Phase IV Study of Panitumumab to Characterize Its Safety, Tolerability and Activity in Indian Subjects With Previously Treated Wild-Type RAS (KRAS and NRAS), Metastatic Colorectal Cancer

This is an open label, multicenter, non-comparative, phase IV study of panitumumab monotherapy in Indian subjects with previously treated, wild-type Kirsten rat sarcoma viral oncogene homolog (KRAS) and wild-type Neuroblastoma rat sarcoma viral (v-ras) oncogene homolog (NRAS), metastatic colorectal cancer. This study is designed to fulfil the requirement of the Indian regulatory authority to characterize the safety and tolerability of panitumumab when administered to Indian subjects with wild-type KRAS and wild-type NRAS metastatic colorectal cancer. Approximately 58 Indian subjects with previously treated wild-type KRAS and wild-type NRAS, metastatic colorectal cancer will be enrolled in order to achieve the target enrollment of 50 evaluable subjects who have received at least one dose of panitumumab. Subjects will receive panitumumab 6 milligram/kilogram (mg/kg) intravenously every 14 days until disease progression, intolerability, withdrawal of consent, or death. All subjects will be followed at 4 weeks and 8 weeks after the last administration of panitumumab, unless the treatment was discontinued due to withdrawal of consent or death of the subject.

Detailed Description

This is an open label, multicenter, non-comparative, phase IV study of panitumumab monotherapy in Indian subjects with previously treated, wild-type Kirsten rat sarcoma viral oncogene homolog (KRAS) and wild-type Neuroblastoma rat sarcoma viral (v-ras) oncogene homolog (NRAS), metastatic colorectal cancer. This study is designed to fulfil the requirement of the Indian regulatory authority to characterize the safety and tolerability of panitumumab when administered to Indian subjects with wild-type KRAS and wild-type NRAS metastatic colorectal cancer. Approximately 58 Indian subjects with previously treated wild-type KRAS and wild-type NRAS, metastatic colorectal cancer will be enrolled in order to achieve the target enrollment of 50 evaluable subjects who have received at least one dose of panitumumab. Subjects will receive panitumumab 6 milligram/kilogram (mg/kg) intravenously every 14 days until disease progression, intolerability, withdrawal of consent, or death. All subjects will be followed at 4 weeks and 8 weeks after the last administration of panitumumab, unless the treatment was discontinued due to withdrawal of consent or death of the subject.

All adverse events occurring from signing of informed consent form until 8 weeks after last dose of panitumumab will be recorded. All Serious Adverse Events (SAE) considered related to panitumumab by the investigator or the sponsor will be followed until the event resolves, or is considered stable or until the subject is lost to follow-up or withdraws consent.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of subjects with adverse event.
Time Frame: 8 months (average duration).

8 months (average duration).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression free survival.
Time Frame: Every 8 weeks (assessed up to average of 6 months)
Progression free survival is defined as the interval between the treatment start date and the earliest date of disease progression per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 or death due to any cause.

Overall Response Rate.
Time Frame: Every 8 weeks (assessed up to average of 6 months).
