Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

How is the study designed?

Participant Group/Arm	Intervention/Treatment
EXPERIMENTAL: Dose Exploration The Dose exploration Phase is made up of Part A, B and Part C. Part A will evaluate the safety and tolerability of MEDI5752 in combination with Axitinib (2 patients), and Part B and C will evaluate the safety and tolerability of MEDI5752 in combination with Lenvatinib (\~72 patients)	BIOLOGICAL: MEDI5752 MEDI5752
EXPERIMENTAL: Dose Expansion Evaluate safety and anti-tumor activity of MEDI5752 in combination with Lenvatinib (\~105 patients )	BIOLOGICAL: MEDI5752 MEDI5752

What is the study measuring?

Primary outcome

Primary Outcome Measure	Primary Outcome Description	Primary Outcome 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
Number of subjects experiencing abnormal electrocardiograms (ECG) reported as Adverse Events.	The primary safety endpoint is as assessed by the change in ECG parameters from baseline.	Informed consent through 90-Day Post Last Dose
Preliminary antitumor activity of MEDI5752 combined with Lenvatinib (or Axitinib) by Objective response rate per RECIST version (v) 1.1.	The primary efficacy endpoint is assessed by the antitumor activity of MEDI5752 combined with Lenvatinib.
