The colorectal patient experienced a partial response with a more than 50% regression in the target tumour as well as stable disease in four, non-treated tumours measured at one month following treatment. A melanoma patient experienced minor regression in the target tumour as well as stable disease in two, non-treated tumours at one and two months following treatment. A lung cancer patient experienced minor regression in the target tumour, as well as stable disease in three, non-treated tumours at two months following treatment.
The treatment has been well tolerated, with mostly Grade 1 or 2 toxicities noted including fatigue, lymphopenia, fever, and neutropenia. Grade 3 toxicities including cellulitis, dysphasia and diarrhoea were related to disease progression and not to the combination treatment. Viral replication was unaffected by cellular irradiation.
The primary objective of the Phase Ia/Ib trial was to determine the maximum tolerated dose ("MTD"), dose limiting toxicity ("DLT"), and safety profile of REOLYSIN(R) when administered intratumourally to patients receiving radiation treatment. A secondary objective is to examine any evidence of anti-tumour activity. Eligible patients include those who have been diagnosed with late stage advanced or metastatic solid tumours that are refractory ("have not responded") to standard therapy or for which no curative standard therapy exists.
Clinical Trials - Actively Enrolling
At the end of the third quarter of 2007, we were actively enrolling in seven clinical trials. In the third quarter of 2007, we commenced enrollment in the following study:
