dose.\n\nDuration of participation will be up to approximately 104 weeks in total per patient.\n\nScreening Period - A maximum screening duration of 4 weeks.\n\nTreatment Period - Up to approximately 104 weeks.\n\nFollow-Up Visit - 4 weeks from last treatment.\n\nLong-term Survival Follow-Up - up to 2 years from last treatment.\n\nA total of up to 66 patients will be enrolled in a non-randomized fashion (patients may be added to any of the dose levels below the RP2D to a maximum of approximately 20 per dose level with the intent of further characterizing safety and pharmacokinetics).'},
