About this study

Official title: A Phase II Clinical Study to Evaluate the Safety and Efficacy of Recombinant hLAG-3 Fusion Protein (EOC202) Injection Combined With Albumin-bound Paclitaxel in Treatment of the Patients With HR Positive, HER2 Negative Advanced Breast Cancer With Progression After Endocrine Therapy

Primary objective:

To evaluate the progression-free survival (PFS) for EOC202 combined with albumin-bound paclitaxel versus albumin-bound paclitaxel alone in treatment of the patients with HR positive, HER2 negative advanced breast cancer (response evaluation criteria in solid tumors, RECIST 1.1);

Secondary objectives:

  1. To evaluate other efficacy variables, such as objective response rate (ORR), disease control rate (DCR), clinical benefit rate (CBR) and overall survival (OS), for EOC202 combined with albumin-bound paclitaxel versus albumin-bound paclitaxel alone in treatment of HR positive, HER2 negative advanced breast cancer;
  2. To evaluate the safety of EOC202 combined with albumin-bound paclitaxel;
  3. To evaluate the immunogenicity of EOC202 combined with albumin-bound paclitaxel;
  4. To evaluate the change level of pharmacodynamic (PD) markers (Interferon-γ, CXCL-10).

Exploratory objectives:

To explore the correlation of baseline soluble MHC-II ligands in blood (lymphocyte activation gene-3 (Lag-3) and fibrin related antigen (FGL-1)) with safety, efficacy, PD and anti-drug antibody (ADA) in subjects in EOC202 combined with albumin-bound paclitaxel group.

Read the detailed description

Overall design:

This is a randomized, open, parallel-controlled study to evaluate the efficacy and safety of EOC202 combined with albumin-bound paclitaxel versus albumin-bound paclitaxel alone in treatment of the patients with HR positive, HER2 negative advanced breast cancer.

This study plans to enroll 50 patients with HR positive, HER2 negative advanced breast cancer who have progression after endocrine therapy and are suitable for taxane therapy, and these patients will be 1:1 randomized into the following two groups for treatment:

Experimental group: EOC202 30 mg+ albumin-bound paclitaxel (100 mg/m2); Control group: albumin-bound paclitaxel (100 mg/m2). One cycle of therapy is 4 weeks (28 days), the subjects in the experimental group will receive albumin-bound paclitaxel 100 mg/m2 iv drip on Day 1 (D1), D8 and D15 of each cycle, and EOC202 30 mg subcutaneously on D2 and D16 of each cycle; the subjects in the control group will receive albumin-bound paclitaxel 100 mg/m2 iv drip on D1, D8 and D15 of each cycle. The treatment will continue until progression of disease, death, intolerable toxicity, start of other antitumor therapy, withdrawal of informed consent, loss of follow-up or termination of study for other reasons, whichever comes first.

No less than 6 cycles of therapy with albumin-bound paclitaxel will be given on the premise it is tolerable by the subject. For the combined therapy, if it is judged by investigators and approved by the sponsor that albumin-bound paclitaxel needs to be discontinued permanently for toxicity, the subject can continue to receive EOC202; on the contrary, if it is judged by investigators and approved by the sponsor that EOC202 needs to be discontinued permanently for toxicity, the subject can continue to receive albumin-bound paclitaxel.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing EOC202 and albumin-bound paclitaxel in people with Solid Tumor, Adult, run by Taizhou EOC Pharma Co., Ltd..

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 17 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: status not confirmed, as of the sponsor's last update on 12 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Ying Tian, VP (+86-021-3175 7830, Ying.tian@eocpharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PFS (time frame: up to 30 months). 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 12 Apr 2022.
