From my read .. birinapant (? Spelling and don’t know what it is) gives tlog about $120M in milestone and also 5% to 10% royalty
So move up could be due to asco meeting in 10 days .. if data is very good, then tlog shares could become vary valuable as total debt is now only about $40M (assume 8% for 3 years and base of $33M in 2016)
And milestones and royalty void dwarf it is birinapat is thought as a good match for keytruda
