Oligoprogression disease is defined as localized treatment failure at one or two anatomic sites, with one to five progressive and measurable (according to RECIST 1.1) lesions, either new or with ≥ 20% growth of their longest diameter (short-axis in lymph nodes), while other tumor manifestations could shrink or grow less than 20% in diameter Exclusion Criteria: Core: 1.

Use of concomitant medication prolonging the QT/QTc interval 7. Evidence of uncontrolled infection or infection requiring a concomitant parenteral antibiotic 8. Evidence of any other significant clinical disorder or laboratory finding that in the opinion of the Investigator may compromise patient safety during study participation. 9.
