Interventions

Combination, Palbociclib + Binimetinibdrug

Patients will then start treatment with continuous oral binimetinib 45 mg/BID and palbociclib 100 mg daily, 21 days on / 7 days off, until disease progression. Study treatment will continue until disease progression. If treatment tolerance is good, after a full cycle patients will be allowed to escalate palbociclib to 125 mg, according to the study investigators' decision. Alternatively, patients with non tolerable grade 2 events will resume at 30 mg/BID of binimetinib upon recovery, maintaining palbociclib at 100 mg 21-on/7-off. Depending on the side-effects, in case of clear relationship with palbociclib is established, palbociclib -instead of binimetinib - will be reduced to 75 mg daily.
