Brief Summary

This study evaluates the safety, tolerability and pharmacokinetics of oral administration of irinotecan in adult patients. Oral irinotecan will be administered as monotherapy in a dose escalation trial to establish the Maximal Tolerated Dose. Totally 25 patients will be treated with irinotecan tablets as mono-therapy. As an extension trial 12 patients will be treated with oral irinotecan in combination with oral capecitabine

Detailed Description

The study is a phase I, open-label, dose escalation single center study in patients with solid tumors. The study will investigate safety, tolerability and Maximal Tolerated Dose as primary end-points of an irinotecan tablet given as single agent or in combination with oral capecitabine. Secondary end-points are pharmacokinetics and preliminary anti-tumor response.

Cohorts of 3 patients will be treated on selected dose level with oral irinotecan in order to identify Dose Limiting Toxicity (DLT) and Maximal Tolerated Dose (MTD). Totally 12 subjects will be treated at the MTD level. Patients will receive irinotecan tablets once daily in the morning for 14 consecutive days within 3 week treatment cycles. As an extension trial totally 12 subjects will be treated with oral irinotecan in combination with oral capecitabine. Patients treated in combination therapy will receive irinotecan tablets once daily in the morning for 14 consecutive days in combination with capecitabine dosed twice daily for 14 consecutive days within 3 week treatment cycles.

• No bowel obstruction or sub-obstruction
• No prior history of intestinal malabsorption
• Patients have to be able to swallow normally and have to be willing to comply with the intake of tablets
• No psychiatric condition that would preclude study participation
• No co-existing active infection requiring antibiotics or any co-existing medical conditions likely to interfere with study procedures
• No other condition that will preclude study participation
• A negative pregnancy test for women of childbearing potential. For men and women of child-producing potential, the use of effective contraceptives methods during the study and at least 3 months after discontinuations of the study drug is required.
• Not pregnant or nursing
• Peripheral neuropathy NCI CTCAE grade less than 2 for patients to be enrolled and treated in combination with oral capecitabine
