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

2017年9月25日 更新者：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

    • DTH tests: administration on 1st day and readout on 3rd day during 2nd and 3rd booster courses (Administration days 64 and 91, readout days 66 and 93)
    • 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.

説明

Inclusion Criteria:

  • Subjects must have adequate tumor tissue from surgery, performed as part of their conventional care.
  • No chemotherapy, radiotherapy, major surgery, or biologic therapy for their malignancy in the 2 weeks prior to vaccine administration and they must have recovered from all side effects.
  • An ECOG performance status of 0, 1, or 2.
  • Age equal to 18 years or older.

  • Blood tests:

    • Platelet counts greater than 80,000 (platelet count, hematocrit, and WBC will be re-evaluated within 2 weeks prior to leukapheresis)
    • Hematocrit > 27.0
    • White blood count > 2000/µL
    • Creatinine less than or equal to 2 X ULN
  • Aware of the neoplastic nature of his/her illness, the experimental nature of the study intervention, alternative treatments, potential benefits and risks, and willing to sign a written informed consent document.

Exclusion Criteria:

  • Subjects currently treated with systemic immunosuppressive agents, including steroids, are ineligible until 2 weeks after removal from immunosuppressive treatment. Subjects on maintenance steroids because of adrenal insufficiency are eligible.

メジャーの説明
時間枠
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.
時間枠：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.
