Trial summary

This phase II trial studies how well pembrolizumab and epacadostat work in combination treating patients with extensive stage small cell lung cancer. Monoclonal antibodies, such as pembrolizumab, may assist the immune system in recognizing cancer cells leading to elimination of those cells. Read more about this study

About this study

Official title: ALCMI-005: Phase II Study of Pembrolizumab and Epacadostat for Small Cell Lung Cancer After Previous Treatment With Platinum-Based Therapy

This phase II trial studies how well pembrolizumab and epacadostat work in combination treating patients with extensive stage small cell lung cancer. Monoclonal antibodies, such as pembrolizumab, may assist the immune system in recognizing cancer cells leading to elimination of those cells. Epacadostat may prevent down-regulation of T-cells, which means it can boost the immune system. Giving pembrolizumab and epacadostat together may work better than either drug alone in treating extensive stage small cell lung cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To assess the objective response rate (ORR) as measured by a modified Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 in subjects with extensive stage small cell lung cancer undergoing treatment with combination pembrolizumab and epacadostat.

SECONDARY OBJECTIVES:

  1. To assess the progression free survival (PFS) as measured by a modified RECIST v1.1 in subjects with extensive stage small cell lung cancer undergoing treatment with combination pembrolizumab and epacadostat.

II. To assess the overall survival in subjects with extensive stage small cell lung cancer undergoing treatment with combination pembrolizumab and epacadostat.

III. To assess the >= grade 3 drug related adverse event profile of combination pembrolizumab and epacadostat in subjects with extensive stage small cell lung cancer.

TERTIARY OBJECTIVES:

  1. To assess tumor genomics, T-cell, myeloid-derived suppressor cells, and receptors (including PD-L1, IDO1, etc) in relation to response rates.

II. To assess cell free deoxyribonucleic acid (DNA) (cfDNA), cell free ribonucleic acid (RNA) (cfRNA), micro RNA (miRNA), and exosomes as predictors for outcomes to treatment with pembrolizumab and epacadostat in subjects with extensive stage small cell lung cancer and to evaluate plasma for predictive markers for outcomes to therapy.

III. Blood samples will be also be stored for future evaluation.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) on day 1 and epacadostat orally (PO) twice daily (BID) on days 1-21. Treatment repeats every 21 days for up to 35 courses in the absence of disease progression or unacceptable toxicity. Patients benefiting from treatment may continue for an additional 17 courses.

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

What is being measured

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

  1. Objective response rate measured by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1

    Proportions and associated confidence intervals will be estimated.

    Measured: Through study completion, an average of 6 months

Secondary outcomes (3)

  1. Progression free survival

    The method of Kaplan-Meier will be used to estimate progression free survival. The Brookmeyer-Crowley method will be used to estimate confidence intervals about median survival times.

    Measured: Through study completion, an average of 6 months

  2. Overall survival

    The method of Kaplan-Meier will be used to estimate overall survival. The Brookmeyer-Crowley method will be used to estimate confidence intervals about median survival times.

    Measured: Up to 24 months

  3. Incidence of grade 3 toxicity

    Binary proportions such as toxicity rates can be estimated to within 15% with 95% confidence.

    Measured: Through study completion, an average of 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pembrolizumab, Epacadostat and Laboratory Biomarker Analysis in people with Extensive Stage Small Cell Lung Carcinoma, run by City of Hope Medical Center at 3 sites 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 19 inclusion and 28 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: withdrawn, as of the sponsor's last update on 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

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 withdrawn before enrolling participants, so there are no results.

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?

Objective response rate measured by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 (time frame: Through study completion, an average of 6 months). 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 NCT03402880.

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 29 May 2026; AzTrials last refreshed its copy on 7 Nov 2026.
