OUTLINE: This is a dose escalation study. Patients receive BIBX 1382 IV over 1 hour followed 7 days later by oral BIBX 1382. Beginning 3 days later, patients receive oral BIBX 1382 daily for 28 days. Courses of daily oral BIBX 1382 repeat every 28 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of oral BIBX 1382. The maximum tolerated dose (MTD) is defined as the dose at which dose limiting toxicity occurs in at least 2 of 6 patients. Patients are followed for up to 4 weeks.
