Study of IMC-11F8 in Participants With Advanced Solid Tumors
- Conditions
- Neoplasms
- Interventions
- Biological: IMC-11F8
- Registration Number
- NCT01088464
- Lead Sponsor
- Eli Lilly and Company
- Brief Summary
This study is to establish the safety and pharmacokinetic (PK) profile of IMC-11F8, administered either: (1) in a 3-week cycle; or (2) in a 2-week cycle to Japanese participants with advanced solid tumors who have not responded to standard therapy or for whom no standard therapy is available.
- Detailed Description
This single center, open-label, single-arm, Phase 1 study will enroll 18 participants at a maximum. The actual size will vary depending on the dose-limiting toxicities (DLTs) observed and the resultant sizes of the cohorts. Participants will receive IMC-11F8 administered intravenously, once every 2 weeks or on Days 1 and 8 every 3 weeks for 6 weeks (1 cycle). All infusions can be administered within ± 1 day of the scheduled administration date. After 1 cycle of treatment, participants who have an objective response or stable disease may continue to receive IMC-11F8 at the same dose and schedule until disease progression or other withdrawal criteria are met.
A minimum of 3 participants will be enrolled in each cohort. Dose escalation in successive cohorts will occur once all participants complete 1 cycle of therapy.
Participants will be enrolled sequentially into each cohort. A completed participant will be either a participant who completes the initial 6-week treatment period (Cycle 1) or a participant who discontinues therapy for an IMC-11F8-related toxicity during Cycle 1. Participants who do not complete the first 6 weeks of treatment for reasons other than an IMC-11F8-related toxicity will be replaced. Toxicity data for each cohort will be reviewed prior to dose escalation. Upon completion of all required safety evaluations during the initial 6 weeks, the next cohort of new participants will be treated at the next higher dose level using a dose escalation scheme.

Name Time Method Number of Participants With 1 or More Treatment-Emergent Adverse Events (TEAEs) or Serious Adverse Events (SAEs) Baseline up to 24 weeks plus 30 days post last dose of study drug Data presented are the number of participants who experienced 1 or more TEAEs or SAEs regardless of causality. An adverse event was considered as TEAE if it occurred any time after the administration of the first dose of study drug or up to 30 days after the last dose of study treatment or if it occurred prior to the first dose and worsened while on treatment. A summary of SAEs and other non-SAEs regardless of causality is located in the Reported Adverse Events module.
