A Safety, Efficacy and Pharmacokinetic Study of Siltuximab (CNTO 328) in Participants With Solid Tumors

May 13, 2014 updated by: Centocor, Inc.

A Phase 1/2, Multiple-Dose, Dose-Escalation Study to Assess the Safety, Efficacy, and Pharmacokinetics of Intravenous CNTO 328, an Anti-Interleukin 6 (IL-6) Monoclonal Antibody, in Subjects With Solid Tumors

The purpose of this study is to determine the recommended dose of siltuximab monotherapy, in participants with solid malignant (cancerous) tumors (a mass in a specific area) and to estimate the clinical benefit of siltuximab monotherapy in participants with ovarian cancer and with Kirsten rat sarcoma viral oncogene homolog (KRAS) mutant tumors.

Detailed Description

This is a 2-part, Phase 1/2, open-label (all people know the identity of the intervention), multiple-dose and dose-escalation study of intravenous (directly into a vein) siltuximab in participants with malignant solid tumors. The study tests the safety and effectiveness of the experimental drug, siltuximab, in participants with advanced cancer (abnormal tissue that grows and spreads in the body). This study also tests how siltuximab is cleared from the body and how the body reacts to it. For this reason blood tests will be performed and some characteristics of the tumor will be analyzed. Siltuximab will be given by intravenous infusion (a fluid or a medicine delivered into a vein by way of a needle) over 1 hour. In Phase 1 (Cohort 1-4) doses will be administered in a range of 2.8-15 milligram per kilogram (mg/kg). Cohort 5 of Phase 1 will receive the recommended dose and schedule as determined from Cohort 1-4. Participants in Phase 1 (Cohort 1-4) will receive 4 administrations of siltuximab over a 10-13 week period, while participants in Cohort 5 and Phase 2 will receive 12 administrations over a 33 week period. Follow-up visits up to 12 weeks after last dose will be scheduled. Participants may then be contacted for up to 1 year after the last dose for follow-up survival and disease status information. Efficacy will primarily be evaluated as per response evaluation criteria in solid tumors (RECIST) criteria. Participants' safety will be monitored at every visit.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Clinical Benefit Response (CBR)
Time Frame: Baseline until disease progression or withdrawal of consent, assessed every 9 weeks up to Week 4 after last dose administration
The CBR is a confirmed complete response (CR), partial response (PR), or stable disease (SD) lasting at least for 6 weeks as per response evaluation criteria in solid tumors (RECIST) criteria. CR: disappearance of all target and non-target lesions and normalization of tumor marker level; PR: at least 30 percent decrease in sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD; SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum LD since treatment started.
Baseline until disease progression or withdrawal of consent, assessed every 9 weeks up to Week 4 after last dose administration

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Overall Response
Time Frame: Baseline until disease progression or withdrawal of consent, assessed every 9 weeks up to Week 4 after last dose administration
Overall response is defined as a confirmed CR or PR using RECIST criteria. CR is defined as disappearance of all target lesions and non-target lesions and normalization of tumor marker level, and PR is defined as at least 30 percent decrease in sum of the LD of target lesions, taking as reference the baseline sum LD.
Baseline until disease progression or withdrawal of consent, assessed every 9 weeks up to Week 4 after last dose administration
Number of Participants With Tumor Marker Response
Time Frame: Baseline until disease progression or withdrawal of consent, assessed every 9 weeks up to Week 4 after last dose administration
According to gynecologic cancer intergroup criteria (GCIC), tumor marker response is defined as at least a 50 percent reduction in tumor marker which must be confirmed and maintained for at least 4 weeks. Tumor marker response is assessed using cancer antigen (CA-125), carcinoembryonic antigen (CEA), CA-19.9 and other markers as available
Baseline until disease progression or withdrawal of consent, assessed every 9 weeks up to Week 4 after last dose administration
Percentage of Participants With Hemoglobin (Hb) Response
Time Frame: Baseline up to Week 4 after last dose administration
The Hb response is defined by an increase of at least 1 gram per deciliter (g/dL) over baseline observed at least once in the absence of transfusion or erythropoietin stimulating agents.
Baseline up to Week 4 after last dose administration
Progression Free Survival (PFS)
Time Frame: Baseline until disease progression or death, assessed every 9 weeks up to Week 4 after last dose administration
The PFS is the time interval between first administration of siltuximab and the first documented sign of progression (at least a 20 percent increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new target or non-target lesions as per RECIST) or death, whichever occurs first.
Baseline until disease progression or death, assessed every 9 weeks up to Week 4 after last dose administration
Overall Survival (OS)
Time Frame: From first dose administration until death, assessed every 3 months up to 12 months after last dose administration
The OS is the interval between first administration of siltuximab and the participant's death from any cause.
From first dose administration until death, assessed every 3 months up to 12 months after last dose administration
European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) Score
Time Frame: Baseline up to 4 weeks after last dose administration
The EORTC QLQ-C30 is used to measure physical function, general health, and global health, as well as participant-reported impression of global quality of life. Symptoms in the scale include: fatigue, pain, and sleep disturbance. It contains 28 items scored using a Likert scale from 1 (not at all) to 4 (very much). 2 additional items are scored from 1 (very poor) to 7 (excellent). Total score ranges from 30-126 with higher score indicating better level of functioning or greater degree of symptoms.
Baseline up to 4 weeks after last dose administration
Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-OV28) Score at Week 4 After Last Dose Administration
Time Frame: Baseline and Week 4 after last dose administration
The EORTC QLQ-OV28 covers side effects of therapy; activity limitation attributable to disease; hormonal symptoms; body image; difficulty with specific bodily functions; and sexual functioning. It contains 28 items scored using a Likert scale from 1 (not at all) to 4 (very much) with a recall period of the past week or, in the final segment, the past 4 weeks. Total score ranges from 28-112 with higher score indicating better level of functioning or greater degree of symptoms.
