I would now like to introduce the CEO of ArQule, Paolo Pucci.
Thank you Bill and good morning everyone and thank you for joining us this morning. I would like to begin by recapping the second-generation program for our lead compound ARQ 197 first-in-class C-Met inhibitor.
The second generating program we have designed and began to implement over the last two years is intended to explore broadly the efficacy of ARQ 197 as a monotherapy specifically C-Met associated soft tissue sarcoma in germ cell tumors and in hepatoma second line therapy.
Also, it’s intended to explore the utility of ARQ 197 in combination in the following tumors: non-small cell lung cancer, colon cancer, gemcitabine-sensitive and sorafenib-sensitive tumors.
Out of all these trials – second generation trials that are ongoing, three are particularly relevant because they are designed as double-blind randomized. The non-small cell lung trial is designed as such, the HCC second line as designed as such and the colon cancer second line 3 (blood) combination is designed as such.
We have very recently reported results from the first of these three phase II double blind randomized trial. The trial that saw the combination of ARQ 197 plus erlotinib compared to erlotinib alone.
Let me give you briefly some summary details of what we have announced and I (inaudible) to say that the study demonstrated that ARQ 197 plus erlotinib yielded a 66% improvement in progression free survival in patients with advanced refractory non-small cell lung cancer.
In the total population of the trial the intent to treat population, that is, which was 167 patients, the median PFS was 16.1 weeks for the ARQ 197 plus erlotinib arm compared with 9.7 weeks in the erlotinib plus placebo arm.
In our interaction with opinion leaders since we announced the data, we have understood that this difference is considered to be meaningful. We have also understood that it was important to demonstrate that the placebo arm performs consistently with historic norms because it makes any comparison to that historic norm for the treatment arm more meaningful.
The difference in PFS between the two arms in the intent to treat population did not reach statistical significance (inaudible) that difference is measured applying a log-rank statistical test. However, when adjusting for imbalances, and we have reported before that imbalances of core relative to two group of patients EGFR (inaudible).
When adjusting for those imbalances in the distribution of the key prognostic practice the difference in PFS between the treatment and placebo arm was statistically significant when measured by applying a Cox regression analysis and such a Cox regression analysis had been pre-specified in our statistical plan for secondary efficacy analysis.
This is for the intent to treat population. Once we look at the largest – all the subgroups that we can examine, we see that improvement in PFS was even more pronounced in the predefined subgroup, or patients with non-squamous histology. This was a large group in number, 117 patients of the 167 total patients enrolled.
