Cohort 2: Has pathologically confirmed diagnosis of unresectable locally advanced or metastatic melanoma that is refractory to or intolerable with at least prior two systemic treatments in the advanced setting for BRAF mutant subjects, or at least one systemic treatment in the advanced setting for BRAF non-mutant subjects. Cohort 3: Has pathologically confirmed diagnosis of unresectable locally advanced or metastatic other solid tumors or lymphomas that is refractory to or intolerable with at least one systemic treatment in the advanced setting, or for which no standard treatment is available. 9.

Uncontrolled hypertension (systolic pressure >150mmHg or diastolic pressure > 90mmHg). Has the average corrected QT interval by Fridericia's formula (QTcF) prolongation to > 480 millisecond (ms) based on 12-lead electrocardiograph (ECG) in triplicate, or with a history of additional risk factors for torsade de pointes (e.g., heart failure, hypokalemia, family history of long QT syndrome or unexplained sudden death under 40 years of age in first degree relatives). Severe gastrointestinal disease, including but not limited to: Peptic ulcer disease in the past 3 months prior to the first dosing.
