PD-1 on its own in Head and neck27 Jan 2019 15:06
Complete responders is as low as 4%
Findings presented at ASCO were based on long-term follow-up of a pooled analysis of the total population of patients across the two head and neck cohorts (n=192). Data showed an ORR (confirmed) of 18 percent (n=34/192) (95% CI, 13-24) – including eight complete responses and 26 partial responses. Thirty-three patients had stable disease and 93 patients had progressive disease. In total, 60 percent of patients experienced a decrease in their target lesions at the time of analysis. The median time to response was two months (range, 2-17 months). While median duration of response had not yet been reached (range, 2+ to 30+ months), 65 percent of responders (n=22/34) were continuing to respond at the time of analysis (85 percent of responses lasted for six months or more with 71 percent lasting for 12 months or more). An analysis of the survival measurements showed a median PFS of two months (95% CI, 1.9-2.1) – with a six-month PFS rate of 25 percent and 12-month PFS rate of 17 percent. The median OS was eight months (95% CI, 6-10) – with a six-month OS rate of 58 percent and a 12-month OS rate of 38 percent.
so inovio with 22 patients is showing superior Complete response rates if it has 2 that puts it at double PD1 on its own approx 8%
which is the same ratio scancell is looking at .. approx doubling efficacy ..............
