If I were them, I would take Met+ to ph3:
Met + 2.9 1.5 0.43 0.19-0.97 0.03
If it was due to disappointment to the result, I think the expectation was too high. This is HCC that failed Nexavar, where nothing really works. For advanced HCC without systematic treatment, Nexavar got the following:
5.5 2.8 0.58 (0.45, 0.74) 0.000007
