Tissue from tumor progressing at a site of prior radiation (at least 6 weeks interval after last radiation) may be allowed for biomarker characterization upon agreement from Merck. Subjects for whom newly-obtained samples cannot be provided (e.g., inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the Merck

Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile-vaginal penetration.
  • Please note that 30 days after lenvatinib is stopped, if the subject is on pembrolizumab only, no male contraception measures are needed
  • A female subject is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
  • Is not a WOCBP OR
  • Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of < 1% per year) and has a low user dependency, or is abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis), as described in Appendix 12.8 during the intervention period and for at least 120 days post pembrolizumab or 30 days post lenvatinib, whichever occurs last.

About this study

Official title: A Pilot Study of Pembrolizumab and Lenvatinib Combination Therapy in Patients With Previously Treated Advanced Gastroesophageal Adenocarcinoma

This early phase I trial studies the effect of pembrolizumab and lenvatinib in treating patients with gastroesophageal adenocarcinoma that has spread to other places in the body (advanced/metastatic) or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and lenvatinib may kill more tumor cells.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To estimate the overall response rate (ORR) of pembrolizumab plus lenvatinib by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 in adult subjects with previously treated advanced (unresectable and/or metastatic) gastroesophageal adenocarcinoma.

SECONDARY OBJECTIVES:

  1. To evaluate the duration of response (DOR), disease control rate (DCR), time-to-progression (TTP), progression-free survival (PFS), using RECIST 1.1 and immune-related (i)RECIST criteria and overall survival (OS).

II. To determine the safety and tolerability of pembrolizumab plus lenvatinib in adult subjects with previously treated advanced (unresectable and/or metastatic) gastroesophageal adenocarcinoma.

EXPPLORATORY OBJECTIVES:

  1. To perform exploratory biomarker analyses to study the correlation between immunological and molecular changes in tumor tissues and peripheral blood with clinical outcomes (DOR, DCR, TTP, PFS, and OS) using RESIST 1.1 and iRECIST.

II. To explore the association between PD-L1 expression by immunohistochemistry (IHC), shed PD-L1 levels, somatic gene expression profiling (18-gene T-cell inflamed GEP) and antitumor efficacy of pembrolizumab based on RECIST 1.1 imaging criteria as well as OS.

III. To explore the relationship between genomic variation and response to the treatment administered.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 and lenvatinib orally (PO) once daily (QD). Treatment repeats every 42 days for up to 17 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 12 weeks.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Lenvatinib and Pembrolizumab in people with Advanced Gastric Adenocarcinoma and Advanced Gastroesophageal Junction Adenocarcinoma, run by M.D. Anderson Cancer Center at 1 site in United States.

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 28 inclusion and 35 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: under way, not looking for participants, as of the sponsor's last update on 16 Jul 2026. 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 United States. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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?

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?

Overall response rate (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05041153.

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 16 Jul 2026.
