Merck ran DDI studies and POLRMT assay with IDX 21437.
The main piece of info lacking with 3422 as I pointed out in earlier post is log 10 viral kill rate in human studies. Those trials are ongoing and results due in 5-6 months. Any prospective buyers will want these results. It's possible that ACHN did get some low-ball offers in the recent past and opted to wait it out for the trial results, much as IDIX did.
