Study Evaluating Inotuzumab Ozogamicin In Acute Lymphocytic Leukemia

2017년 3월 2일 업데이트: Pfizer

An Open-label, Phase 1/2 Study Of Inotuzumab Ozogamicin In Subjects With Relapsed Or Refractory Cd22-positive Acute Lymphocytic Leukemia

The Phase 1 portion of this study will assess the safety, tolerability and efficacy at increasing dose levels of inotuzumab ozogamicin in subjects with CD22-positive relapsed or refractory adult acute lymphocytic leukemia (ALL) in order to select the recommended phase 2 dose (RP2D) and schedule. The Phase 2 portion of the study will evaluate the efficacy of inotuzumab ozogamicin as measured by hematologic remission rate (CR + CRi) in patients in second or later salvage status.

Optional blood samples for pharmacogenomic parameters were collected during Cycle 1 prior to the start of the inotuzumab ozogamicin infusion (0 hours) and 1 hour post-dose (original Final Protocol and Protocol Amendments 1 and 2) or 3 hours post-dose (Protocol Amendments 3 and 4) on Day 1 and Day 15 from those participants who provided consent. Gene expression analysis of samples collected pre- and post-dosing was performed using 96-gene TaqMan® low density array cards to examine the concordance between clinical outcome and expression of genes such as those involved in DNA damage response, apoptosis, B-cell antigen expression, glutathione metabolism, drug transport and the phosphoinositide 3-kinase/mammalian target of rapamycin pathway. Expression for each gene was reported as a normalized value, 2^-change in (∆) threshold cycle (Ct), where ∆Ct is Ct^target gene minus Ct^reference genes, averaged.
