I'd follow NVS INC280 development closely to see if they deviate from Roche's MET development model, especially what combination they would try. At this point, it seems they are following Tivantinib as monotherapy in HCC. I would assume they saw activity in HCC from ph1, which is good for Tivantinib in HCC.
Well, as jq noted, they seem to be pursuing similar strategy as ARQL (monotherapy in HCC) and they are well behind in it. I will concede that they presumably have the better partner in NVS (vs. Daiichi Sankyo for ARQL), but I like where ARQL is right now already having begun to enroll patients in the pivotal P3 HCC trial after the positive P2 HCC results (http://investors.arqule.com/releasedetail.cfm?ReleaseID=679317 ).
