What is being measured

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

  1. Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of of ES102

    The MTD and/or RP2D of ES102 will be determined.

    Measured: 2-3 years

  2. Number of participants with adverse events and serious adverse events of ES102

    The safety profile of ES102 will be assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5.0.

    Measured: 2-3 years

Secondary outcomes (6)
  1. Area under the serum concentration time curve (AUC) of ES102

    Area under the serum concentration time curve (AUC) of ES102 will be determined.

    Measured: 2-3 years

  2. Maximum observed serum concentration (Cmax) of ES102

    Maximum observed serum concentration (Cmax) of ES102 will be determined.

    Measured: 2-3 years

  3. Trough observed serum concentration (Ctrough) of ES102

    Trough observed serum concentration (Ctrough) of ES102 will be determined.

    Measured: 2-3years

  4. Time to Cmax (Tmax) of ES102

    Time to Cmax (Tmax) of ES102 will be determined.

    Measured: 2-3years

  5. Immunogenicity of ES102

    Frequency of anti-drug antibodies (ADA) against ES102 will be determined.

    Measured: 2-3years

  6. Anti-tumor activity of ES102

    Tumor response will be determined by the revised Response Evaluation Criteria in Solid Tumors version 1.1 (RECISTv1.1).

    Measured: 2-3years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ES102 in people with Solid Tumors and Neoplasms, run by Elpiscience Biopharma, Ltd. at 1 site in China.

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 19 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 23 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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?

Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of of ES102 (time frame: 2-3 years). The study lists 2 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 23 Jun 2025.
