About this study

Official title: A Pilot Study of Combination Immunotherapy With Ipilimumab and Nivolumab in Patients With Recurrent Extensive Stage Small Cell Lung Cancer (SCLC) Who Have Previously Received Platinum-based Chemotherapy

This is a pilot study of patients who previously received platinum chemotherapy with recurrent SCLC to evaluate the change in the ratio of intratumoral Teff/Treg cells and clinical benefit of treatment with nivolumab and ipilimumab.

Read the detailed description

The primary objective of this study is t assess whether the change in the ratio of effector T cells (Teff) to regulatory T cells (Treg), i.e. CD8 positive/FoxP3 expressing CD4 T cells, between pre- and on- treatment biopsies, will predict clinical response in patients with recurrent SCLC treated with combination therapy with nivolumab and ipilimumab.

Secondary objectives of the study include: to determine the objective response rate per RECIST 1.1 and immune-related response criteria, duration of response, progression free survival, and overall survival with nivolumab and ipilimumab in patients with recurrent SCLC; to evaluate changes in the tumor immune microenvironment and blood after treatment with ipilimumab and nivolumab; and to evaluate circulating tumor DNA (ctDNA) as a marker for response to therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Combination immunotherapy with Ipilimumab and NivolumabDrug

    Patients will be treated with nivolumab 1 mg/kg and ipilimumab 3 mg/kg, starting on Day 1. Patients will receive 4 doses of each nivolumab and ipilimumab and then will receive nivolumab 240 mg starting week 13 (day 85) every 2 weeks until progression, unacceptable toxicity, withdrawal of consent, or the study ends, whichever occurs first.

What is being measured

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

  1. Change in the ratio of Teff/Treg cells

    The primary analysis will use the nonparametric Mann-Whitney sign test to compare the change in the ratio of Teff/Treg cells in those patients who respond or not to treatment. This test compares the rate of response in those with above and below Teff/Treg ratio.

    Measured: Up to 24 months

Secondary outcomes (3)
  1. Response rate

    Objective response is defined as a complete or partial response, as determined by investigator assessment using RECIST v1.1 and immune-related response criteria (irRC) . Response will be confirmed by repeat assessments ≥4 weeks after initial documentation. Patients not meeting these criteria, including patients without any post baseline tumor assessment, will be considered non-responders in the analysis of objective response.

    Measured: Up to 24 months

  2. Duration of response

    Duration of response is defined as the time from the initial complete or partial response to the time of disease progression or death, whichever occurs first. If a patient does not experience death or disease progression before the end of the study, duration of response will be censored at the day of the last tumor assessment. If no tumor assessments were performed after the date of the first occurrence of a complete or partial response, duration of objective response will be censored at the date of the first occurrence of a complete or partial response plus 1 day.

    Measured: Up to 24 months

  3. Progression-free survival

    Progression-free survival (PFS) is defined as the time from the first day of treatment until progression of disease using RECIST v1.1 and immune-related response criteria (irRC) . If a patient has not experienced progressive disease or death, PFS will be censored at the day of the last tumor assessment. Patients with no post baseline tumor assessments will be censored at the date of first study treatment plus 1 day.

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Combination immunotherapy with Ipilimumab and Nivolumab in people with Small Cell Lung Cancer, run by Yale University 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 5 inclusion and 21 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 20 Jul 2025. 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?

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?

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?

Change in the ratio of Teff/Treg cells (time frame: Up to 24 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 20 Jul 2025.
