There are 3 clinical trials
This is a study on how to activate the immune system with a vaccine. The vaccine is made up of two proteins found in breast cancer: telomerase and survivin. The vaccine is given in combination with other drugs that may also have an effect on the immune system and attack the cancer. The goals of the study are: 1. to test the safety of the combination of agents 2. to find out what effects the treatment has on advanced breast cancer
The two "heteroclitic" peptides are R572Y (YLFFYRKSV) and D988Y (YLQVNSLQTV), which bind HLA-A2 with high avidity and elicit specific CTL (cytotoxic T lymphocyte) responses using healthy donor mononuclear cells in vitro. --- R572Y ---
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.
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). --- D988Y --- --- R572Y ---
Description: Incidence of delayed hematopoietic recovery and the incidence of Grade 3 or greater autoimmune eventsMeasure: Primary toxicity endpoint Time: 2 yrs
RATIONALE: Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Thalidomide may stop the growth of cancer cells by stopping blood flow to the cancer. A stem cell transplant using stem cells from the patient may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells. Giving an infusion of the donor's T cells after the transplant may help destroy any remaining cancer cells. PURPOSE: This phase I/II trial is studying the side effects of stem cell transplant given together with chemotherapy and biological therapy and to see how well it works in treating patients with high-risk or refractory multiple myeloma.
