Phase 1/2a DTA-H19 in Patients With Unresectable Pancreatic Cancer
This study is designed to assess the safety, tolerability, pharmacokinetics (PK) and preliminary efficacy of DTA-H19 administered intratumorally in patients with unresectable, locally advanced pancreatic cancer.
Primary Objective: The primary objective is to determine the maximum tolerated dose (MTD) of intratumoral DTA-H19 and identify any dose limiting toxicities (DLTs).
Secondary objectives include determining the adverse events (AEs) profile, effects on clinical laboratory analytes, vital signs, PK, tumor response, and possible tumor resectability after 4 intratumoral administrations of DTA-H19.
|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase 1/2a, Dose-Escalation, Safety, Pharmacokinetic, and Preliminary Efficacy Study of Intratumoral Administration of DTA-H19 in Patients With Unresectable Pancreatic Cancer|
- Tolerability: The primary safety outcome measure is the MTD. To determine the MTD, DLTs will be assessed in each dose cohort [ Time Frame: 4 weeks ] [ Designated as safety issue: Yes ]
- Tumor response [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
- Tumor resectability [ Time Frame: 5 to 6 weeks ] [ Designated as safety issue: No ]
|Study Start Date:||August 2009|
|Primary Completion Date:||October 2010 (Final data collection date for primary outcome measure)|
DTA-H19, is a doubled stranded DNA plasmid that carries the gene for the diphtheria toxn A (DT-A) chain under the regulation of the H19 promoter sequence. This is a Patient-Oriented, Targeted Therapy as DT-A chain expression is triggered by the presence of H19 transcription factors that are upregulated in tumor cells. The selective initiation of toxin expression results in selective tumor cell destruction via inhibition of protein synthesis in the tumor cell, enabling highly targeted cancer treatment.
