Brief summary

The study is evaluating the maximum tolerated dose (MTD) by understanding the safety profile during incremental dosage escalation. Who is it for? You may be eligible to join this study if you are aged over 18 years with any histologically confirmed relapsed or refractory advanced haematologic malignancies for which no effective standard therapies are available, and have progressed following at least one prior treatment regimen. As every blood cancer patient has a unique disease and treatment history, it is highly suggested that you discuss the trial with your haematologist or oncologist who can also contact Peter Mac to determine whether this trial may be suitable for you. Trial details Participants in this study will receive CX-5461, an RNA polymerase I inhibitor. CX-5461 will be administered by intravenous infusion over 1 hour on day 1 and day 8 every 28 days. Four dose levels are planned: 70 mg/m2, 100 mg/m2, 150 mg/m2 and 220 mg/m2 per dose. Patients will be assigned to a dose level in the order of study entry. Participants will be required to undergo various assessment tests including blood, imaging, laboratory and physical assessment tests.
