Study Summary

This trial looks at the side effects and effectiveness of ESK981 in treating patients with prostate cancer that has spread to other parts of the body. ESK981 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Eligible Conditions
  • Castration-resistant Prostate Cancer
  • Prostate Cancer
  • Low Testosterone
  • Prostate-Specific Antigen

Trial Design

1Treatment groups
Experimental Treatment
Group I: Treatment ESK981Experimental Treatment1 Intervention
Patients receive pan-VEGFR/TIE2 (Vascular Endothelial Growth Factor Receptor/angopoeitin receptor2) tyrosine kinase inhibitor CEP-11981 PO QD for 5 days (Monday-Friday). Treatment repeats for up to 8 weeks in the absence of disease progression or unacceptable toxicity. If treatment is successful after 8 weeks, patients may receive up to 6 months of pan-VEGFR/TIE2 tyrosine kinase inhibitor CEP-11981.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Has ESK981 been granted regulatory authorization by the Food and Drug Administration?

"ESK981's safety was rated a 2 on our scale of 1-3 due to limited efficacy data and the fact that this is an early Phase 2 trial."

Answered by AI

Does this research project currently have the capacity to include more participants?

"This clinical trial is no longer open to new patients, as can be seen on the clinicaltrials.gov website. The project began in March of 2018 and was last updated August 30th 2022. That being said, there are 3650 other medical studies that still need volunteers right now."
