These are RCC patients with clear cell histology, treated using the PME-CD40L DC product. At present, 6 of the 12 patients that have been restaged using RECIST criteria have less tumor burden that when they enrolled in the study (15 weeks earlier).

Monocyte-derived and cocktail-matured DC electroporated with a combination of RNAs encoding tumor antigens (MelanA, Mage3, Survivin) and E/L-selectin are currently used in a clinical trial. Most patients having received the vaccine already demonstrated broad responses to numerous peptides prior vaccination. Significantly enhanced responses to several peptides and occurrence of new responses was seen in 6 patients, 5 of which were vaccinated with E/L-S+ DC. These data provide evidence for a superior immunopotency of E/L-selectin expressing DC.

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.

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.

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).

Aiming at finding possible reasons for the discrepancies between our findings and published data could be the amount of ONTAK used in patients, we filed an amendment to the clinical trial allowing the inclusion of additional 4 patients. These patients will receive higher doses (12microg/kg 3x and 18microg/kg 1x) before vaccination. Taking into account direct effects of ONTAK on DC, patients will be vaccinated some days after last ONTAK treatment (as soon as blood DC have recovered to 50% of pre ONTAK amount). Third stage of DERMA-ER-DC 05 clinical trial.

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 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 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...

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).

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.

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

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.

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

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.

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

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.
