Study on Efficacy and Tolerability of Vorinostat in Patients With Advanced, Metastatic Soft Tissue Sarcoma (STS)

• Status: Completed
• Trial end date: 2013-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Primary objective of the study is to investigate the efficacy of vorinostat in patients suffering from selected histological types of soft tissue sarcoma. Further evaluations relate to the safety and tolerability of vorinostat, its pharmacokinetics (course of plasma concentration over time) and pharmacodynamics (mode of action). Only subjects with advanced, metastatic disease will be included in this trail.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Heidelberg University
• Collaborator: Merck Sharp & Dohme Corp.
• Treatments: Vorinostat

Criteria

Inclusion Criteria:
