Brief Summary:
This clinical trial is an open label Phase II study of the combination of intravenously administered SGT-53 and gemcitabine/nab-paclitaxel in patients with metastatic pancreatic cancer as a first-line treatment. The objective of the study is to evaluate the safety, tolerability, toxicity and efficacy (specifically Progression Free Survival at 5.5 month (PFS5.5mos)) of this combination therapy.

Condition or disease Intervention/treatment Phase
Metastatic Pancreatic Cancer Genetic: SGT-53 Drug: nab-paclitaxel Drug: Gemcitabine Phase 2

Detailed Description:
The p53 is a vital human tumor suppressor gene. Loss of p53 suppressor function is present in the majority of human cancers. The p53 protein has a diverse range of functions including regulation of cell cycle checkpoints, cell death (apoptosis), senescence, DNA repair, maintenance of genomic integrity, and control of angiogenesis. Abnormalities of the p53 gene may impact the efficacy of standard anticancer treatments such as radiation and chemotherapy. P53 mutation and pathway dysfunction are associated with poor clinical outcomes and the presence of the p53 mutation correlates with resistance to chemotherapy and radiation. The development of somatic gene therapy has created the potential to restore wild type function of p53. SGT-53 is a complex of cationic liposome encapsulating a normal human wild type p53 DNA sequence in a plasmid backbone. This complex has been shown to efficiently and specifically deliver the p53 cDNA to the tumor cells. Introduction of the p53 cDNA sequence is expected to restore wtp53 function in the apoptotic pathway. P53 restoration has been shown most effective in enhancing cytotoxicity in combination with an agent which results in DNA damage or initiates apoptosis. This is a Phase II clinical trial of SGT-53 plus the recently approved chemotherapeutic combination of gemcitabine/Abraxane® (nab-paclitaxel) as a first-line therapy in patients with confirmed metastatic pancreatic cancer. In addition to determining Progression Free Survival at 5.5 months (PFS5.5mos), this trial will evaluate the response rate, overall survival and time to progression as well as the tolerability and safety of SGT-53 in combination with gemcitabine/nab-paclitaxel.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 28 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Study of Combined Targeted p53 Gene Therapy (SGT-53) Plus Gemcitabine/Nab-Paclitaxel for Treatment of Metastatic Pancreatic Cancer
Study Start Date : January 2015
Estimated Primary Completion Date : December 2019
Estimated Study Completion Date : December 2020


Arm Intervention/treatment
Experimental: SGT-53 with gemcitabine/nab-paclitaxel
A course of therapy will include 7 weeks of treatment. In week 1, SGT-53, at 2.4 mg DNA/infusion, will be administered on day 1 and day 5, 1000 mg/m² gemcitabine and 125 mg/m² nab-paclitaxel will be administered on day 3 of each week except week 4. If the combination is well-tolerated, starting at week 2, 3.6 mg DNA/infusion of SGT-53 will be administered bi-weekly on days 1 and 5 in weeks 2-3, weekly on day 3 in week 4, and weekly on day 1 in weeks 5-7. Patients who are responding to treatment may receive one additional course (7 weeks) of SGT-53/gemcitabine/nab-paclitaxel therapy at investigator discretion. If still responding to treatment, they may continue on gemcitabine/nab-paclitaxel alone at investigator discretion.
Genetic: SGT-53
The starting dose of SGT-53 in week 1 will be 2.4 mg DNA/infusion. If the combination therapy of SGT-53 and gemcitabine/nab-paclitaxel is tolerated, starting in week 2, the dose of SGT-53 will be escalated to 3.6 mg DNA/infusion. If necessary, the dose of SGT-53 can be de-escalated to 1.2 mg DNA/infusion (dose level -1) or 0.6 mg DNA/infusion (dose level -2) in the event that increased toxicity probably or definitely related to SGT-53 is observed with the combination.

Drug: nab-paclitaxel
The dose of nab-paclitaxel will be 125 mg/m² and will be administered once weekly (day 3) in weeks 1, 2, 3, 5, 6 and 7. If increased toxicities related to administration of nab-paclitaxel is observed, the dose of nab-paclitaxel can be reduced to 75 or 100 mg/m² when appropriate.
Other Names:
  • Abraxane ABI-007
  • Albumin-bound paclitaxel

Drug: Gemcitabine
The dose of gemcitabine will be 1000 mg/m² and will be administered once weekly (day 3) in weeks 1, 2, 3, 5, 6 and 7, after the administration of nab-paclitaxel. If increased toxicities related to administration of gemcitabine is observed, the dose of gemcitabine can be reduced to 750 mg/m² when appropriate.
