Exclusion Criteria: * Any condition that, in the opinion of the investigator, would interfere with evaluation of the investigational product or interpretation of subject safety or study results * Concurrent enrollment in another clinical study, unless it is an observational study. * Previous treatment with mTOR inhibitors, PD-1, PD-L1, or CTLA-4 inhibitors for RCC or any other immune checkpoint inhibitor * Previous treatment with VEGF inhibitors * Evidence of the following infections: active infection including tuberculosis, human immunodeficiency virus, chronic or active hepatitis B or chronic or active hepatitis C * History of organ transplant * Active or prior documented autoimmune or inflammatory disorders * Current or prior use of immunosuppressive medication within 14 days prior to the first dose of investigational product. * Poorly controlled blood pressure (BP) defined as systolic BP ≥ 140/90 mmHg at screening and not able to be controlled prior to Cycle 1 Day 1 and any change in antihypertensive medications within 1 week prior to Cycle 1 Day 1. * Thromboembolic (arterial or venous) events within previous 6 months * Any concurrent therapy for cancer * Receipt of live attenuated vaccine within 30 days prior to the first dose of investigational product * Known allergy or hypersensitivity to investigational product(s) or any of the excipients of the investigational product(s) * Untreated or progressive CNS metastatic disease, any leptomeningeal disease, or cord compression * History of another primary malignancy * Unresolved toxicities from previous anticancer therapy * Major surgery within 4 weeks prior to enrollment or radiation therapy within 2 weeks prior to enrollment or has not recovered from AEs due to prior treatment * Female subjects must not breastfeed and must not donate, or retrieve for their own use, ova from screening to 3 months after the last dose of MEDI5752 and 30 days after the last dose of lenvatinib. * History of arrhythmia which is symptomatic or requires treatment, symptomatic or uncontrolled atrial fibrillation despite treatment, or asymptomatic sustained ventricular tachycardia * Uncontrolled intercurrent illness within the last 6 months prior to enrollment * Clinically significant gastrointestinal abnormality * Serious nonhealing wound, ulcer, or bone fracture * Has clinically significant hemoptysis (at least 0.5 teaspoon of bright red blood) or tumor bleeding within 2 weeks before the first dose of investigational product * Radiographic evidence of major blood vessel invasion/infiltration/encasement

Outcomes

Primary Outcomes

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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Secondary Outcomes

Antitumor activity of MEDI5752 combined with Lenvatinib by measuring the progression free survival (PFS) according to RECIST v1.1.

The endpoint for assessment of PFS is defined as the time from the first dose of treatment until the documentation of PD or death due to any cause, whichever occurs first.

Time frame: Last Subject Enrolled through study completion, an average of 48 months.

Antitumor activity of MEDI5752 combined with Lenvatinib by measuring the Best Overall Response (BOR) according to RECIST v1.1.

The endpoint for assessment of BOR will be based on all post-baseline disease assessments that occur prior to the initiation of subsequent anticancer treatment

Time frame: First subject enrolled through 18 months from last subject enrolled, an average of 30 months.

Antitumor activity of MEDI5752 combined with Lenvatinib by measuring the Disease Control Rate (DCR).

The endpoint for assessment of DCR is measured by the proportion of subjects with a BOR of confirmed CR, PR, or SD.

Time frame: Informed Consent through the date of first documented progression, end of study, date of death, or two years after last subject starts treatment whichever should occur first

Antitumor activity of MEDI5752 combined with Lenvatinib by measuring the Duration of Response (DOR) according to RECIST v1.1.

The endpoint for assessment of DOR is measured by the duration from the first documented OR to the first documented PD or death due to any cause, whichever occurs first.

Time frame: Informed Consent through the date of first documented progression, end of study, date of death, or two years after last subject starts treatment whichever should occur first

Antitumor activity of MEDI5752 combined with Lenvatinib by measuring the Time to Response (TTR) according to RECIST v1.1.

The endpoint for assessment of TTR is defined as the time from the first dose of treatment until the first documentation of an OR.

Time frame: Informed Consent through the date of first documented progression, end of study, date of death, or two years after last subject starts treatment whichever should occur first

Pharmacokinetics of MEDI5752: Cmax

The endpoints for the assessment of PK of MEDI5752 include individual MEDI5752 concentrations at different time points after administration.
