Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To demonstrate a 25% reduction of the active irinotecan metabolite, SN38, in healthy liver tissue (without reducing the intra-tumoral SN38 concentration), 24-26 hours after irinotecan administration with preceding dietary restriction compared to without preceding dietary restriction. | — |
Secondary
| Measure | Time frame |
|---|---|
| - To determine intra-tumoral irinotecan and SN-38 concentrations with and without preceding dietary restriction. - To determine the systemic PK parameters of irinotecan in peripheral blood with and without preceding dietary restriction. - To determine leukocyte number with and without preceding dietary restriction - Toxicity of irinotecan with and without preceding dietary restriction. - Transcriptome analysis of tumor and liver to identify mechanisms responsible for increased intra-tumoral irinotecan concentrations and decreased side effects. | — |
