  • Whenever possible, a formalin-fixed, paraffin-embedded (FFPE) tumor tissue block or 5-10 unstained slides of tumor sample (archival) should be made available (less material is acceptable);
  • Participants must have a life expectancy of 16 weeks or more.
  • Active infection including: tuberculosis, hepatitis B (known positive hepatitis B surface antigen (HBsAg) result) and/or, hepatitis C. Patients with a past or resolved hepatitis B infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA (indicating no current infection).

What is being measured

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

  1. Phase 1: Unacceptable Serious Adverse Events (SAEs)

    Unacceptable toxicity status at the end of 13-week safety observation period with unacceptable toxicity defined as:

    • Any grade 4 immune related adverse event (irAE),
    • Any ≥ grade 3 noninfectious pneumonitis,
    • Any ≥ grade 3 colitis,
    • Any grade 3 irAE, excluding colitis or pneumonitis, that does not downgrade to grade 2 within 7 days after onset of the event despite optimal medical management including systemic corticosteroids or does not downgrade to ≤ grade 1 or baseline within 14 days,
    • Liver transaminase elevation > 8 × Upper Limit of Normal (ULN) or total bilirubin > 5 × ULN
    • Any ≥ grade 3 non-irAE with exceptions per protocol

    Measured: 13 weeks

  2. Phase IB: Progression Free Survival

    Progression Free Survival (PFS) defined as the duration from date of registration to date of first documentation of progression assessed by local investigator or symptomatic deterioration or death due to any cause. Patients last known to be alive are censored at date of last contact.

    Measured: 6 months

Secondary outcomes (2)
  1. Median Progression Free Survival

    Progression Free Survival (PFS) is defined as the duration from date of registration to date of first documentation of progression assessed by local investigator or symptomatic deterioration (as defined above) or death due to any cause. Patients last known to be alive are censored at date of last contact.

    Measured: Up to 12 months

  2. Overall Survival

    Overall Survival (OS) will is defined as the duration from date of registration to date of death due to any cause. Patients last known to be alive are censored at date of last contact.

    Measured: Up to 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Durvalumab, Tremelimumab and Olaparib Pill in people with Small Cell Lung Cancer Extensive Stage and Small-cell Lung Cancer, run by H. Lee Moffitt Cancer Center and Research Institute 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 17 inclusion and 16 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 1 Apr 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Phase 1: Unacceptable Serious Adverse Events (SAEs) (time frame: 13 weeks). The study lists 2 primary outcomes in all. 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 1 Apr 2026.
