Phase I/II Clinical Trial Combining hTERT Tumor Vaccine & Autologous T Cells in Patients With Advanced Myeloma
Phase I/II Combination Immunotherapy After ASCT for Advanced Myeloma to Study HTERT Vaccination Followed by Adoptive Transfer of Vaccine-Primed Autologous T Cells

The purpose of this study is:

  1. To evaluate the safety of activated T cell infusions and immunization with hTERT multi-peptide vaccine in the post-transplant setting and whether the combination can delay hematopoietic recovery or induce other autoimmune events.
  2. To determine whether the strategy of infusing vaccine-primed T-cells early after transplant in conjunction with post-transplant boosters leads to the induction of cellular immune responses to hTERT.

This protocol proposes to combine two different investigational products to test the hypothesis that autologous T cell therapy can augment the potency of a putative tumor vaccine post- stem cell transplant, and lead to a myeloma-directed T-cell mediated "graft vs. myeloma" effect in patients with advance myeloma. The hope is that this combination therapy approach will result in a more rapid recovery of acquired immunity and consequently increased cure rates and better clinical outcomes. The two investigational products to be evaluated in this Phase I/II study include:

  1. hTERT Vaccine (the putative tumor vaccine)- a multi-peptide vaccine consisting of 3 peptides against the catalytic subunit of telomerase (hTERT D988Y, I540, and R572Y), 1 survivin peptide (Sur1M2- an antiapoptotic protein), and 1 CMV (cytopeptide (N495).
  2. T cell therapy- T-cells isolated from the patient and activated/expanded ex vivo by antiCD3/28 beads.

This is a two-site study at the University of Pennsylvania and University of Maryland to recruit a total of fifty-six study patients. The key eligibility criteria are patients who have systemic or multifocal myeloma requiring autologous stem cell transplantation. After enrollment, patients will be divided into two arms (A and B) according to their HLA A2 status (A = HLA A2 +, B = HLA A2-). Patients in ARM A will be initially immunized with the hTERT vaccine along with a pneumococcal conjugate vaccine (PCV); patients in ARM B will be initially immunized and given boosters of PCV only. All patients will undergo T-cell harvest, stem cell mobilization and collection, high-dose chemotherapy, autologous stem cell transplant (ASCT), and an infusion of expanded T cells at day 2 after ASCT. Patients in ARM A will then receive three hTERT/PCV vaccine boosters at day 14, 42, and 90 after ASCT.

Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Multiple Myeloma
  • Biological: Telomerase (hTERT vaccine + pneumococcal conjugate vaccine (PCV))
    One vaccination prior to autologous transplant and 3 vaccination after autologous transplant.
  • Biological: PCV vaccine
    Receipt of PCV vaccine and GM-CSF injections prior to autologous transplant and post transplant
  • Experimental: ARM A

    ARM A Injection 1 and 2 the telomerase vaccination, followed by GM-CSF, which will also be injected at the same site in order to make the vaccinations work better.

    Injection 3 and 4 (deep part of the skin in the left thigh)- the survivin and CMV vaccination, followed by GM-CSF.

    Injection 5 - the PCV vaccination.

    Intervention: Biological: Telomerase (hTERT vaccine + pneumococcal conjugate vaccine (PCV))
  • Active Comparator: ARM B
    ARM B Injection 1: PCV vaccination Injection 2 GM-CSF injection Injection 3 : GM-CSF injection
    Intervention: Biological: PCV vaccine

Each subject must meet ALL of the following criteria during screening to be enrolled in the study:

  1. Written informed consent must be obtained from all patients before entry into the study
  2. Patients must have a diagnosis of myeloma
  3. Patients must meet one of the following criteria:

    • Myeloma has relapsed, progressed, or failed to respond after at least one prior course of therapy.
    • Myeloma has responded partially to initial therapy but neither a complete nor a near-complete response has developed after at least 3 cycles or months of initial therapy.
    • Myeloma has high-risk features
  4. Patients must have measurable disease on study entry.
  5. Patients must be between ages 18-80 (inclusive).
  6. Patients should have adequate vital organ function.
  7. ECOG performance status 0-2
  8. Women of child-bearing potential (WOCBP) and their spouses or partners must be willing to use adequate contraception for the duration of the active treatment phase of the study and for at least 4 months after the last dose of chemotherapy. In addition, contraceptive measures must be continued as long as the patient remains on maintenance thalidomide in accordance with the STEPS program.

Key Exclusion Criteria

Subjects who meet ANY of the following criteria cannot be enrolled in the study:

  1. Pregnant or nursing females
  2. HIV, HTLV-1/2 seropositivity
  3. Known history of myelodysplasia
  4. Known history of chronic active hepatitis or liver cirrhosis (if suspected by laboratory studies, should be confirmed by liver biopsy).
  5. Active Hepatitis B
  6. Prior autotransplant or allogeneic transplant
  7. More than 4 distinct, prior courses of therapy for myeloma
  8. History of severe autoimmune disease requiring steroids or other immunosuppressive treatments.
  9. Active immune-mediated diseases including: connective tissue diseases, uveitis, sarcoidosis, inflammatory bowel disease, multiple sclerosis.
  10. Evidence or history of other significant cardiac, hepatic, renal, ophthalmologic, psychiatric, or gastrointestinal disease which might increase the risks of participating in the study
  11. Active bacterial, viral or fungal infections.
