Safety of Labeled Dendritic Cell (DC) Vaccines and Feasibility of Tracking by Magnetic Resonance Imaging (MRI)

25 września 2017 zaktualizowane przez: Pawel Kalinski

Safety and Feasibility Evaluation of the MRI-based Tracking of Alpha-type-1 Dendritic Cell Vaccines in Patients With Colorectal Cancer

This study will evaluate the safety and feasibility MRI tracking of a vaccine produced from a persons cancer cells injected intradermally once a day for 3 consecutive days. One of the daily doses will contain a chemical that can be detected by an MRI. That will be either the 1st or 3rd day of the 3 day course. On that day MRI scans will be performed 6 and 24 hours after the injection on that day. Patients may be able to receive booster doses every 1-2 months

    • Biopsy of the DTH site can be performed in any subject who consented to such biopsy, at the discretion of the investigator/sub-investigator (3rd day of 3 day course, based on readout of DTH test)
    • Blood for in vitro assays (1st and 3rd day of each 3 day course)
  • Procedures on Day 105

    • Complete physical examination (with ECOG PS and weight)
    • CEA levels in the blood (as a tumor marker)
    • CBC, platelet, differential
    • Comprehensive metabolic panel (CMP) including: glucose, BUN, creatinine, sodium, potassium, Cl, CO2, calcium, total protein, albumin, alkaline phosphatase, AST, ALT, total bilirubin
    • Radiologic imaging to evaluate the status of disease may be performed as a part of routine care
    • Photography
  • Long term follow-up The subjects with lack of disease progression at 6 months after the last vaccination will be monitored for the disease free survival and overall survival. Subjects may be contacted every 3 months within the first three years after study intervention, every six months until year 5, and annually afterwards. In lieu of direct contact a medical record review may be performed to obtain the data for these time points for disease progression and/or survival.

Ramy czasowe
Comparative analysis of the effectiveness of lymph node accumulation of DC vaccines injected to resting versus pre-activated nodes (DCs injected on day 1 versus day 3 of the three day-long vaccination cycle.
Ramy czasowe: 1 year

Effectiveness of DC accumulation may be correlated with their effectiveness in inducing immune responses as measured by:

  • Increase in the magnitude in the DTH response to: A) autologous tumor lysates (primary endpoint of efficacy); B) KLH; and c) saline (control); all injected intradermally.
  • Peripheral blood CD8+ and CD4+ T cell responses against autologous tumor cells, using IFNγ-ELISPOT readout.
  • In any HLA-A2+ subjects on the protocol, we may evaluate peripheral blood CD8+ T cell responses against CRC-related peptide epitopes present, using IFN ELISPOT as readout.
1 year
May assess the disease-free survival and overall survival
