About this study

Official title: TRIMPACT: A Prospective Real-World Study of Atezolizumab Monotherapy as First-Line (Stage IV) Treatment in Patients With Non-Small Cell Lung Cancer With PD-L1 Tumor Cell Expression ≥50% and No Targetable Mutations

This prospective, multicenter, real-world observational study aims to evaluate the clinical outcomes of first-line atezolizumab monotherapy in patients with stage IV non-small cell lung cancer (NSCLC) with PD-L1 tumor cell expression ≥50% and no targetable mutations. The study aim to determine how atezolizumab performs in routine clinical practice with respect to survival, treatment response, and safety outcomes in this patient population in Türkiye.

Read the detailed description

This study is a prospective, multicenter, observational study designed to generate real-world evidence on the routine first-line use of atezolizumab in patients with advanced non-small cell lung cancer (NSCLC) who exhibit high PD-L1 expression and have no targetable mutations. The study does not impose any protocol-mandated procedures or intervention requirements, and all assessments, treatments, and follow-up visits are carried out according to local standards of care at each participating center.

Data will be collected prospectively from routine medical records and will include information typically obtained during standard clinical management, such as imaging assessments, laboratory results, performance status evaluations, treatment exposure, and safety monitoring. Clinical outcomes will be analyzed to describe real-world treatment patterns, variations in clinical practice, and survival and safety trends in a national cohort. Approximately 150 patients are expected to be enrolled to ensure adequate precision in estimating long-term outcomes within this population.

What participants receive

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

Study groups in NCT07279402
Study groupRoleWhat they receive
Atezolizumab Real-World CohortThis observational cohort consists of patients with stage IV non-small cell lung cancer (NSCLC) who receive first-line atezolizumab in routine clinical practice. Participants are included based on real-world treatment decisions made by their physicians, and no study-mandated interventions or procedures are required. The cohort reflects patients treated according to local standards of care, allowing evaluation of real-life treatment patterns, clinical outcomes, and safety in this population.

What is being measured

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

  1. Overall Survival (OS)

    Overall survival (OS) is defined as the time from the initiation of atezolizumab treatment to the date of death from any cause.

    Measured: Up to 24 months

Secondary outcomes (7)
  1. Progression-Free Survival (PFS)

    Progression-free survival (PFS) is defined as the time from the initiation of atezolizumab treatment to the first date of objectively documented disease progression (PD) or death from any cause, whichever occurs first. Progression will be assessed by the treating physician according to local standard clinical practice or RECIST criteria when available.

    Measured: Up to 24 months

  2. Objective Response Rate (ORR)

    Objective response rate (ORR) is defined as the proportion of patients who achieve a complete response (CR) or partial response (PR) during atezolizumab treatment.

    Measured: Up to 24 months

  3. Disease Control Rate (DCR)

    Disease control rate (DCR) is defined as the proportion of patients whose best overall response is complete response (CR), partial response (PR), or stable disease (SD) during atezolizumab treatment.

    Measured: Up to 24 months

  4. Duration of Response (DoR)

    Duration of response (DoR) is defined as the time from the date of first documented complete response (CR) or partial response (PR) to the first date of objectively documented disease progression or death from any cause, whichever occurs first.

    Measured: Up to 24 months

  5. One-year Overall Survival (1-year OS)

    One-year overall survival is defined as the incidence of death from any cause within 12 months following the initiation of atezolizumab treatment.

    Measured: 12 months

  6. Incidence of Hyperprogression

    The incidence of hyperprogression is defined as the proportion of patients who exhibit rapid tumor progression after initiation of atezolizumab, according to the criteria specified in the study protocol.

    Measured: Up to 24 months

  7. Incidence of Adverse Events (AEs), Serious Adverse Events (SAEs) and Adverse Events of Special Interest (AESIs)

    The incidence, nature, and severity of adverse events (AEs), serious adverse events (SAEs), and adverse events of special interest (AESIs) will be assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE v5.0). Safety evaluations include monitoring and recording of AEs and SAEs, laboratory results, vital signs, and other clinically relevant assessments performed as part of routine clinical practice.

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of NSCLC Stage IV and PD-L1 Gene Mutation, run by Antalya Training and Research Hospital at 25 sites in Turkey (Türkiye).

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 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: looking for participants now, as of the sponsor's last update on 30 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 25 sites in Turkey (Türkiye). 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.

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?

Contact Derya Kıvrak Salim (+90 533 648 82 17, derya.kivraksalim@sbu.edu.tr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Survival (OS) (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 30 Apr 2026.
