XK469R in Treating Patients With Refractory Hematologic Cancer

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Phase I trial to study the effectiveness of XK469R in treating patients who have refractory hematologic cancer. Drugs used in chemotherapy, such XK469R, work in different ways to stop cancer cells from dividing so they stop growing or die

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

• Lead Sponsor: National Cancer Institute (NCI)
