PharmaMar Presents Pharmacogenomic Data on Yondelis(R) at CTOS

    Boca Raton, Florida, November 22 (ots/PRNewswire) - PharmaMar announces the presentation of data from two research projects at the 11th Annual CTOS (Connective Tissue Oncology Society) Meeting, which took place in Florida, USA, from November 19-21, 2005.

    The first presentation highlighted data from a retrospective study conducted in tumour samples from patients of soft tissue sarcoma treated with Yondelis(R) in Europe, while the second presentation examined  the results of a preclinical study of Yondelis in cell lines explanted from chemo-naïve patients.

    Yondelis(R) - two oral presentations

    1. "A deficient homologous recombination DNA repair appears to cluster sarcoma patients sensitive to Yondelis(R) (ET-743, trabectedin)" was a retrospective study conducted in tumour samples from patients with sarcoma treated with Yondelis in Europe that seeks to provide a greater understanding of sensitivity/resistance to Yondelis by examining the molecular signature of the tumours. The results indicate that patients with a defined pattern of tumour DNA repair efficiency have a higher probability of better survival. They are expected to have a major impact on the optimisation of Yondelis in studies in solid tumours that are sensitive to Yondelis.

    2. "Mutated P53 correlates with extreme sensitivity to Yondelis(R) in low passaged cell lines explanted from chemonaïve sarcoma patients" showed molecular evidence that correlates extreme in vitro sensitivity to Yondelis(R) with mutation of the p53 gene. Such evidence, in contrast with the pattern applicable to classical chemotherapeutic agents, provides a useful tool for patients' improvement strategies in prospective studies.

    Commenting on the CTOS presentations, José Jimeno, VP of Scientific Development at PharmaMar, said, "The data presented at the CTOS meeting demonstrate the selective and targeted effects of Yondelis and reinforce the significant novelty of this marine-derived compound. Should these preliminary findings be confirmed by further studies, they may constitute a relevant tool to improve patients' treatment with Yondelis and to enhance the drug profile in prospective clinical trials."
