I've looked over the ASTRO conference program and I don't see anything that's a good fit for Dr. Scher and Apoptone.

But there is a conference in Boston two weeks later that looks like it might be the one. Here's the link but you may have to copy and paste in the url line.

It's for the American Association for Cancer Research (AACR) and the title of the conference is Molecular Targets and Cancer Therapeutics.

Here's one of the presentations:

Circulating tumor cells as biomarkers in the development of the androgen receptor antagonist, MDV3100
Howard I. Scher, Memorial Sloan-Kettering Cancer Center, New York, NY, USA
No mention of Apoptone, but maybe he'll sneak a comment or two in.
