London, June 6, 2012 - Silence Therapeutics plc (AIM: SLN) ("Silence" or the "Company"), a leading global RNA interference (RNAi) therapeutics company, on Monday presented the latest data from its ongoing Phase I study of Atu027, its lead internal therapeutics candidate, alongside the 2012 American Society of Clinical Oncology ("ASCO") Annual Meeting in Chicago, Illinois. At this meeting, Klaus Giese, Ph.D., Silence's Chief Scientific Officer and the study's principal investigator Dr. Dirk Strumberg, Professor of Medicine and Director of Department of Hematology and Medical Oncology at University of Bochum (Marienhospital Herne, Germany), gave an update and discussed the data from the Atu027 Phase I trial.
Silence's open label, single-centre, dose-finding Phase I study of Atu027 in subjects with advanced solid cancer was designed to evaluate up to a total of 11 escalating doses of Atu027. The enrolment of patients in the last cohort in dose level 10 has been completed and last treatment is scheduled on 22nd of June 2012. Atu027 was very well tolerated and safe up to the 10th dose level. No premedication was needed in support of Atu027 treatment. The prospective recommended maximum tolerated dose is 0.336 mg/kg. "Stable disease" response for three and six months after treatment was observed in 10 and 3 patients, respectively, of the 33 evaluable patients. Two patients with neuroendocrine cancer had disease stabilisation for 9 and 12 months. Partial regression of pulmonary metastases was found in another patient. A further patient with breast cancer showed regression of liver metastases.
