BruCells is developing allogeneic dendritic cell fusion vaccines as a therapeutic cancer immune therapy targeted at treating glioma or renal cell carcinoma (RCC). The active substance consists of hybrid cells resulting from the fusion of allogeneic dendritic cells (DC) with allogeneic glioma or RCC tumour cells. Therefore the fusion vaccine qualifies as a somatic cell therapy medicinal product, as defined in Part IV (Advanced therapy medicinal products) of annex I to Directive 2001/83/EC (1), as amended by Directive 2003/63/EC (2). (1) Directive 2001/83/EC...

aHLA-DR fluorescein isothiocyanate was used to label yeast and spores.

We investigated the interactions between human monocyte derived DCs (MDDC), generated in the presence of GM-CSF and IL-4 (IL-4 DC), and antigen-stimulated circulating gamma delta T lymphocytes, bearing the Vgamma2 TCR. The studies demonstrated for the first time the existence of a bidirectional activating interaction between DCs and gamma delta T lymphocytes activated by aminobiphosphonates. These data suggest a potential adjuvant role of this early cross-talk in the therapeutic activity of aminobiphosphonate drug that are currently used as anti-tumor drugs.

This construct was used as in the transfection of immature DC.

2 ml of acid phenol were added to the buffered and incubated S. cerevisia cells after transferral of the supernatant to a new tube.

One volume fresh medium containing 2x concentrated cytokines was added to the cell culture of monocytes in serum free medium in the presence of 100 ng/mL GM-CSF (Leukine, Berlex) and 20 ng/mL IL-4 (Cell Genix).

These patients with Previously Treated B-cell Chronic Lymphocytic Leukemia are taking part in a clinical study and receive multiple injections of CLL-DCV01.

This supernatant was used for staining. Four out of 600 supernatants used, i.e. 2C44, 2F74, 2E60 and 2X8, readily stained LACK156-173-pulsed fibroblasts, but neither unpulsed fibroblasts nor OVA323-339-pulsed cells.

An HIV infected individuals stable under HAART study has been initiated. These patients are being vaccinated with cytokine cocktail matured DCs electroporated with mRNA encoding Tat, Rev and Nef. The cDNA’s encoding these early expressed HIV antigens have been human codon optimized and modified with lysosomal targeting sequences. So far, 17 patients have been included in the study.

These dendritic cells were generated from monocytes isolated from buffy coats, activation was induced by lipopolisaccaride (LPS 1microgram/ml, Sigma, St. Louis, MO), by Curdlan (100 micrograms/ml, Wako), by R848 and yeast RNA and by yeast cells in different conditions of culture.

These adherent peripheral blood monocytes are produced from leukapheresis from HLA-A1 and/or HLA-A2 positive patients with stage III/IV melanoma, used to generate DCs from. The latter will subsequently be used to vaccinate the HLA-A1 and/or HLA-A2 positive patients.

The vaccine is composed by autologous DCs electroporated with mRNA encoding CD40L, CD70, caTLR4 and one tumorantigen (gp100, Tyrosinase, Mage-C2 or Mage-A3).

Alternatively activated DC (AA-DC) were obtained by culturing immature DC in the presence of maturative agonists (such as, LPS, CD40L or TNF) and calcitriol, IL-10 or prostaglandin E2 for a study of molecular signatures for alternatively activated DC. AA-DC showed a decrease in the production of IL-12 but retained most of the ability to secrete other cytokines, such as TNF and CXCL8. The hallmark of AA-DC was the production of the angiogenic cytokine VEGF in vitro, and in vivo when the cells were implanted into the chicken embryo CAM assay.

Four patients are enrolled in a clinical trial for vaccination with DC loaded with apoptotic leukemic cells. A strong type I T cell response has been induced. Preliminary data also indicate reduction of circulating tumor cells. No adverse effects have been observed.

These 70 patients were evaluated in the DERMA-ER-DC 04 clinical trial of DC-based therapy of melanoma patients (multipeptide loaded cytokine matured moDC +/- CD40L activation). The analysis for the first time showed a clinical correlation of induced immune responses as measured in the blood with outcome, as there have been so far statistically significantly less events in stage III patients showing good CTL reponses (IFN-y Elispot) to multiple class I and II peptides compared to low responders of the stage III cohort. Additional in vitro maturation of DC by CD...

These patients are taking part in a clinical study. They are patients that are successfully treated with highly active anti-retroviral therapy (HAART) with no measurable viral load AND have a cryopreserved infectious plasma sample that was drawn immediately prior to initiation of HAART. They are administered 4 monthly doses of the Arcelis product.

These patients received multipeptide loaded cytokine matured moDC + prior Treg elimination by 3x ONTAK treatment [5µg/kg]; first phase of DERMA-ER-DC 05 trial.

77 patients have been enrolled in two Phase III trials from 2 institutions testing dosing or duration of IM administration (EORTC 62005 and BFR14 trials).
