Study summary

This is a Phase 1, open-label, non-randomized, dose-escalation study to determine the maximum tolerated dose (MTD), safety, tolerance, and pharmacologic profile of EZN-2968, a locked nucleic acid antisense oligonucleotide against hypoxia-inducible factor 1α administered as a 2-hour intravenous (i.v.) infusion weekly for 3 weeks per 6-week cycle. In patients treated at a recommended Phase 2 dose of EZN-2968, dose intensification will proceed by maintaining the dose, but gradually increasing the number of doses per 6-week cycle. Up to 3 intensification cohorts will receive the recommended Phase 2 dose of EZN-2968.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 7, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
