Clinical Trial VICCHEM1392


A Phase 1, Open-label, Dose-Escalation Study of the Safety of SNX-5422 Mesylate in Subjects with Refractory Hematological Malignancies

Principal Investigator(s)

Nishitha Reddy


  • Protocol No. VICCHEM1392
  • Open Date: 03/12/2014
  • Staging: Phase I
  • Age Group: Adults
  • Scope: National
  • Objective: To characterize the safety profile of SNX-5422 when administered once every other day for 21 days (total=11 doses) of 28-day schedule.
  • Disease Sites: Leukemia; Lymphoma; Multiple Myeloma
  • Therapies: Molecular Targeted Agents / Immunotherapy / Biologics
  • Drugs: SNX-5422
  • Participating Institutions: Vanderbilt University
  • National Clinical Trial ID: NCT01635712
  • Secondary Protocol No: SNX-5422-CLN1-005


Patients are being asked to take part in this research study because they have cancer that has not responded to other treatments and no other treatments are available. This study will involve treatment with an experimental drug called SNX-5422 mesylate (referred to simply as SNX-5422). The main purpose of this study is to determine the highest dose of SNX-5422 that can be tolerated when given once every other day for 21 days. Other goals of this study are to study its side effects, to measure its possible effects on the tumor, and to further study how this drug works.
