Patients with PD-L1 expressing solid tumors which have relapsed or are refractory to prior treatment will be eligible to participate in this study.\n\nFollowing completion of the multiple ascending dose study, the protocol may be amended to include expansion cohorts in patients with melanoma and/or other solid tumors.\n\nThis is a multiple ascending dosing (MAD) study of up to 6 treatment regimens cohorts based on using a 3+3 design (up to 36 patients overall). The principal objective is to establish the maximum tolerated dose, safety, tolerability and pharmacokinetic (PK) profile in blood and urine of this HDAC6 inhibitor in patients with solid tumors and to explore effects on pharmacodynamic markers of target engagement and response to treatment.\n\nDaily/twice daily doses will be given as open label monotherapy. A review of safety and PK data will be conducted once the last patient in each cohort reaches day 28 of treatment. The review will confirm the dose to be used for the subsequent cohort. Dose escalation will be continued until the MTD is reached. Upon completion of the dose escalation phase of the study, dose expansion phases will be planned.\n\nPatients responding to treatment may elect to remain on therapy until disease progression, death or the investigator decides to stop treatment.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
