About this study

Official title: A Phase IIa Open-Label Trial of AGEN1884 in Combination With Pembrolizumab in Subjects With Chemotherapy Naïve, PD-L1 High, Metastatic Non-Small Cell Lung Cancer (NSCLC)

A Phase IIa Open-Label Trial to Investigate the Safety, Tolerability, Pharmacokinetics, Biological, and Clinical Activity of AGEN1884 in Combination with Pembrolizumab in Subjects with Chemotherapy Naïve, PD-L1 high, metastatic Non-Small Cell Lung Cancer (NSCLC)

Read the detailed description

This is a Phase IIa, open-label study, of AGEN1884 in combination with pembrolizumab in subjects with stage IV NSCLC whose tumors have high PD-L1 expression and no EGFR or ALK genomic tumor aberrations.

The study consists in two phases:

  • Safety Run-in Phase
  • Efficacy Phase

Subjects will be enrolled in a "3+3" Safety Run-in followed by enrollment completing the efficacy cohort. Two different dose levels of AGEN1884 may be tested in combination with the approved pembrolizumab treatment for this indication (until disease progression, unacceptable toxicity, or up to a maximum of 24 months). Each subject will stay on the dose level assigned at trial entry.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AGEN1884 in combination with pembrolizumab in people with NSCLC Stage IV, run by Agenus Inc. at 5 sites in 2 countries.

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 19 inclusion and 20 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: stopped early, as of the sponsor's last update on 2 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Australia, New Zealand. 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 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?

The study was stopped early (reason given: Trial will not proceed due to changes in the treatment landscape.). Results are not available in the source record.

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?

Occurrence of DLTs in subjects in the Safety Run-in Phase of the trial (time frame: 21 days). 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 NCT03411473.

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 2 Jun 2020; AzTrials last refreshed its copy on 8 Nov 2026.
