What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of subjects experiencing adverse events (AEs)/serious adverse events (SAEs)	The primary safety endpoint is as assessed by the number of subjects with adverse events and serious adverse events (SAEs) graded per NCI CTCAE v5.0.	Informed consent through 90-Day Post Last Dose.
Number of Participants With Dose Limiting Toxicities (DLT) of MEDI5752 and Lenvatinib (or Axitinib) during the Dose Exploration period.	Determine the MTD and recommended Phase 2 dose (RP2D) of the combination of MEDI5752 and Lenvatinib. A dose limiting toxicity (DLT) is defined as MEDI5752 treatment-related AE of any Grade 3 or higher toxicity (as defined in the protocol) CTCAE v5.0.	Informed consent through the first 21 days of treatment with MEDI5752 and Lenvatinib (or Axitinib) in the Dose Exploration Period.
Number of subjects experiencing adverse events (AEs) leading to discontinuation.	The primary safety endpoint is as assessed by the number of subjects with serious adverse events (SAEs) graded per NCI CTCAE v5.0.	Informed consent through 90-Day Post Last Dose.
Number of subjects experiencing abnormal laboratory evaluations.	The primary safety endpoint is as assessed by the number of subjects experiencing changes in laboratory evaluations from baseline.	Informed Consent through 90 post treatment date.
Number of subjects experiencing changes in vital signs reported as Adverse Events.	The primary safety endpoint is assessed by the change in vital signs from baseline.	Informed consent through 90-Day Post Last Dose
