Great work ATLhsider. Even when 3 months on trial are subtracted from the DCVax-L trial to approximately make up the time elapsed between surgery and initiation of chemo, the blended DCVax-L trial demonstrates a superior survival pattern.
Fig 2a of the 2018 JTM publication shows for the blended trial at about a 1 year survival post chemo (about 15 months post surgery), a 75% survival rate and at 2 years post chemo (about 27 months post surgery), a 42% survival (give or take about 1%).
I am also guessing that by 39 months post chemo (36 months post surgery), the added 3 months would not have reduced the 28.2% survival rate to less than 25%.
Survival rates of 75%, 42% and 25% at 1, 2 and 3 years, are still far better than were presented or would have been expected from the four trials you used as comparisons with the DCVax-L blended data.
I also trust that the survival rates of the Treatment group will be significantly higher than those obtained from the blended trial.
In summary, it is highly unlikely that the first endpoint will fail.
