This is a Phase 1, open-label study evaluate the safety, tolerability, pharmacokinetics, immunogenicity and anti-tumor activity of MEDI5752 in Japanese patients with advanced solid solid tumors.

Read the detailed description

<Objectives>

Primary Objective:

To evaluate the safety and tolerability of MEDI5752 in Japanese subjects with advanced solid tumors.

Secondary Objective:

To assess the anti-tumor activity and efficacy of MEDI5752. To describe the pharmacokinetics of MEDI5752.

Exploratory Objective:

To conduct exploratory research into factors that may be predictive of response or may influence the progression of cancer and/or response (efficacy) to MEDI5752.

Eligible patients will be administered as a single dose at each Cycle Day1. Each cycle from Cycle 1 has a duration of 21 days.

A minimum of 3 and a maximum of 9 evaluable patients will be enrolled in each cohort.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The number of subjects experiencing treatment related adverse events (AEs)

    The primary endpoint is as assessed by the number of subjects experiencing adverse events (AEs) graded per NCI CTCAE v5.0.

    Measured: From the time of informed consent through 90 days following termination of treatment with investigational product

  2. The number of subjects experiencing treatment related serious adverse events (SAEs)

    The primary endpoint is as assessed by the number of subjects with serious adverse events (SAEs) graded per NCI CTCAE v5.0.

    Measured: From the time of informed consent through 90 days following termination of treatment with investigational product

  3. The number of subjects experiencing dose-limiting toxicities (DLTs)

    The primary endpoint is as assessed by the number of subjects experiencing dose limiting toxicities (DLTs) as defined by the protocol.

    Measured: Up to 21 days following the first dose

  4. The number of subjects experiencing abnormal laboratory evaluations

    The primary endpoint is as assessed as the number of subjects experiencing changes in laboratory parameters from baseline.

    Measured: From the time of informed consent through 90 days following termination of treatment with investigational product

  5. The number of subjects experiencing changes from baseline in vital signs reported as adverse events

    The primary endpoint is as assessed by the number of subjects experiencing clinically significant changes in vital signs from baseline.

    Measured: From the time of informed consent through 90 days following termination of treatment with investigational product

  6. The number of subjects experiencing abnormal electrocardiograms (ECG) reported as Adverse Events

    The primary endpoint is as assessed by the the number of subjects experiencing clinically significant changes in ECG parameters from baseline.

    Measured: From the time of informed consent through 90 days following termination of treatment with investigational product

Secondary outcomes (4)
  1. Preliminary anti-tumor activitiy of MEDI5752 using Objective Response based on RECIST v1.1

    The endpoints for assessment of antitumor activity is defined by using ORR, PFS, BOR,DCR, DoR and TTR according to RECIST v1.1.

    Measured: From the first dose of study drug through the date of documented progression, end of study, or date of death until study completion assessed up to 16 months.

  2. Pharmacokinetics of MEDI5752

    The endpoints for the assessment of PK of MEDI5752 include individual MEDI5752 concentrations at different time points after administration. (e.g., Maximum plasma concentration[Cmax])

    Measured: At Cycle1Day1, ,Cycle1Day2, Cycle1Day3, Cycle1Day8, Cycle1Day15, Cycle2Day1, Cycle2Day8, Cycle3Day1, Cycle4Day1, Cycle5Day1, Cycle6Day1, Cycl7Day1, every 6 weeks after Cycle7Day1 (each cycle is 21 days) and up to 90 days following end of treatment.

  3. Immunogenicity of MEDI5752

    The endpoints for the immunogenicity of MEDI5752 include the number of subjects who develop detectable anti-drug antibodies (ADAs)

    Measured: At Cycle1Day1, Cycle1Day8, Cycle1Day15, Cycle2Day1, Cycle2Day8, Cycle3Day1, Cycle4Day1, Cycle5Day1, Cycle6Day1, Cycl7Day1, every 6 weeks after Cycle7Day1 (each cycle is 21 days) and up to 90 days following end of treatment.

  4. PD-L1 Expression in subjects with advanced solid tumors

    The endpoint for the PD-L1 expression will be determined by Immunohistochemistry characterization.

    Measured: To be assessed at at baseline

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MEDI5752 in people with Advanced Solid Tumors, run by AstraZeneca at 2 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The number of subjects experiencing treatment related adverse events (AEs) (time frame: From the time of informed consent through 90 days following termination of treatment with investigational product). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2025.
