Safety Study of Infusion of SGT-53 to Treat Solid Tumors
This study is currently recruiting participants.
Verified by SynerGene Therapeutics, Inc., January 2009
Sponsored by: SynerGene Therapeutics, Inc.
Information provided by: SynerGene Therapeutics, Inc.
ClinicalTrials.gov Identifier: NCT00470613
  Purpose

The purpose of this study is to evaluate the safety of a single course of SGT-53 and determine the recommended dose for evaluation in subsequent clinical studies for the treatment of solid phase tumors.


Condition Intervention Phase
Neoplasm
Genetic: SGT53-01
Phase I

MedlinePlus related topics: Cancer
U.S. FDA Resources
Study Type: Interventional
Study Design: Treatment, Non-Randomized, Open Label, Dose Comparison, Single Group Assignment, Safety Study
Official Title: A Phase I Open-Label Safety and Pharmacokinetic Study of Escalating Doses of SGT-53 for Infusion in Subjects With Advanced Solid Tumors

Further study details as provided by SynerGene Therapeutics, Inc.:

Primary Outcome Measures:
  • Safety will be assessed by analysis of adverse experiences, clinical laboratory tests, and physical examinations. [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Pharmacokinetic parameters and response of tumor [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 10
Study Start Date: February 2008
Estimated Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Genetic: SGT53-01
    SGT-53 will be infused i.v. two times per week for five weeks. Each subject will receive only one of six dose levels. Dose levels will escalate from 0.6 mg DNA per infusion to 7.2 mg DNA per infusion.
Detailed Description:

The p53 gene is a vital tumor suppressor gene in humans. Numerous human tumors possess a loss or mutation of wild type p53 (wtp53). In addition to playing a crucial role in cell cycle control, the p53 gene is a critical component in two of the pathways involved in regulating tumor cell growth: cell death (apoptosis) and the regulation of angiogenesis. The loss of such critical tumor suppressor activity is believed to be responsible for p53's involvement in such a broad array of human tumors and resistance to chemo/radiotherapy. SGT-53 is a complex composed of a wild type p53 gene (plasmid DNA) encapsulated in a liposome that is targeted to tumor cells by means of an anti-transferrin receptor single-chain antibody fragment (TfRscFv) attached to the outside of the liposome. This phase 1 dose escalation clinical study is designed to evaluate the safety and maximum tolerated dose (MTD) of SGT-53. In addition, pharmacokinetics of escalating doses of SGT-53 will be measured and correlated with tumor response and toxicity.

  Eligibility

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Have a biopsy confirmed diagnosis thereby providing histological diagnosis of a solid tumor malignancy.
  • Have been offered all standard or approved therapies for which they would be considered eligible and have specifically declined or decided to postpone.
  • Have solid tumors that can be measured on physical examination or by radiographic imaging studies.
  • Be 18 years old or older.
  • Have an ECOG performance study of 0, 1 or 2.
  • Be able to give informed consent.
  • Have recovered from any previous therapy side effects or toxicities prior to initiating protocol study infusions.
  • Have a life expectancy of more than 12 weeks.
  • Female subjects of childbearing potential must have a negative pregnancy test within 7 days before initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.
  • Male and female subjects of reproductive potential must agree to use measures (e.g., condoms or birth control pills) to avoid pregnancy throughout the study and for 3 months following discontinuation of the study drug.
  • Organ function characterized by </= Grade 1 scores defined by CTCAE v3.0.
  • Laboratory values meeting the following criteria:

    • Hemoglobin >/= 10.0 gm/dL
    • Absolute neutrophil count > 1500/mm3
    • White blood cell count > 3000/mm3
    • Platelet count >/= 100,000/mm3
    • PT/PTT < 1.5 times the upper limit of normal
    • LDH < 3 times the upper limit of normal but without concomitant elevations in any of the following: PT, PTT, or D-dimer or clinical evidence of Disseminated Intravascular Coagulation
    • Total bilirubin </= 1.5 times the upper limit of normal
    • AST and ALT </= 2.5 times the upper limit of normal
    • Creatinine </= 1.5 mg/dL or creatinine clearance >/= 50 ml/minute

Exclusion Criteria:

  • Have hematological malignancy
  • Are pregnant or lactating women
  • Have signs and symptoms consistent with an active infection
  • Fever (> 38.1oC)
  • Treated with antibiotics for infection within one-week prior to study entry
  • Known HIV infection
  • Have any history of psychiatric disorders that would interfere with informed consent or follow-up.
  • Have any other concurrent disease that, in the judgment of the investigator, would contraindicate the administration of study drug or interfere with the study evaluations.
  • Have diastolic blood pressure of > 90 mm Hg resting at baseline despite medication. (Acceptable if on hypertensive medication and diastolic blood pressure is </= 90 mm Hg.)
