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.
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.
