A Phase 1/2 Study of Oral SB1518 in Subjects With Chronic Idiopathic Myelofibrosis

This study has been completed.

S*BIO Identifier:
First received: September 2, 2008
Last updated: April 19, 2012
Last verified: April 2012
The study consists of two phases: The first portion of the study is a Phase 1 dose escalation study to determine the maximum tolerated dose and the dose limiting toxicities of SB1518 when given as a single agent orally once daily in subjects with Chronic Idiopathic Myelofibrosis (CIMF) regardless of their JAK2 mutational status. The second portion of the study is a Phase 2 study to define the efficacy and safety profile of single agent SB1518 at the recommended dose in subjects with CIMF.

Primary Outcome Measures:
  • Phase 1: to establish the maximum tolerated dose of SB1518 as a single agent when administered orally daily [ Time Frame: Throughout the study ]
  • Phase 2: to assess the clinical benefit rate in subjects with CIMF who are treated with SB1518 at the recommended dose [ Time Frame: Throughout the study ]

Secondary Outcome Measures:
  • Assess the safety and tolerability of SB1518, administered orally once daily in subjects with CIMF [ Time Frame: Throughout the study ]
  • Assess the pharmacokinetic profile of SB1518 [ Time Frame: Throughout the study ]
  • Assess the pharmacodynamic profile of SB1518 [ Time Frame: Throughout the study ]
