About this study
Official title: A Phase 3, Randomized, Open-Label, Active-Controlled, Superiority Trial of EG007, Added to the Combination of Lenvatinib Plus Pembrolizumab vs. Lenvatinib Plus Pembrolizumab in Patients With Advanced Endometrial Cancer
This is a Phase 3, multicenter, randomized, open-label trial to evaluate whether EG-007 plus Len+Pem is superior to Len+Pem alone in patients with advanced endometrial cancer (Stage III or IV). This trial will be preceded by a safety lead-in study with up to 28 patients (the safety lead-in is a separate, free-standing protocol).
Approximately 450 patients will be randomized equally (1:1) to receive EG-007 plus Len+Pem or Len+Pem alone. The randomization will be stratified by the following stratification factors:
- Diagnosis Classification (advanced Stage III/IV vs. recurrent endometrial cancer)
- ECOG score at baseline (0 vs 1)
- Geographic region (Asia vs ROW)
- Conditions
- Advanced Endometrial Cancer
- Being tested
- EG-007, Pembrolizumab 100 mg/ 4 ml (25 mg/ml) Injection, Lenvatinib Capsules

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing EG-007, Pembrolizumab 100 mg/ 4 ml (25 mg/ml) Injection and Lenvatinib Capsules in people with Advanced Endometrial Cancer, run by Evergreen Therapeutics, Inc..
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 11 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: opening soon, as of the sponsor's last update on 8 Dec 2025. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Xin Du, Ph.D. (2404064016, david.du@egpharm.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival (PFS) (time frame: Up to 35 Cycles of 21 days). 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 Dec 2025.
