About this study

This is a Phase II, single-arm, multicenter trial for patients with metastatic non-small cell lung cancer who have brain metastases and no known actionable mutations. Eligible patients will receive a combination of Datopotamab-deruxtecan, Carboplatin, and Pembrolizumab every three weeks for four cycles, followed by maintenance therapy with Datopotamab-deruxtecan and Pembrolizumab until disease progression or intolerable toxicity. Patients with intracranial progression but no systemic progression may receive stereotactic radiosurgery and continue treatment based on the investigator's decision.

Read the detailed description

This is a phase II, single-arm, multicenter trial. Patients with metastatic NSCLCs with brain metastases and without known actionable mutations will be enrolled. Patients who are eligible for the study will receive Datopotamab-deruxtecan 6 mg/kg, Carboplatin AUC 6, and Pembrolizumab 200 mg flat dose every three weeks, for four cycles, followed by maintenance of Datopotamab-deruxtecan 6 mg/kg and Pembrolizumab 200 mg until unacceptable toxicity or disease progression.

Patients who present intracranial progression but do not present concurrent systemic progression may undergo stereotactic radiosurgery and continue systemic therapy on study as per investigator's decision.

Patients will undergo medical evaluation and laboratory tests (hematology and blood chemistry) every 3 weeks. Abdomen/pelvis and chest CT scans, as well as brain MRIs, will be obtained at baseline, every 6 weeks during the first 24 weeks, then every 9 weeks (±7 days). Patient reported outcomes will be assessed using EORTC QLQ-C30 and QLQ-LC13 questionnaires at baseline and during treatment.

Being tested
Pembrolizumab, Datopotamab deruxtecan, Carboplatin
Medical subject headings

What participants receive

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

  • PembrolizumabDrug

    Pembrolizumab is a potent humanized immunoglobulin G4 (IgG4) monoclonal antibody (mAb) with high specificity of binding to the programmed cell death 1 (PD-1) receptor, thus inhibiting its interaction with programmed cell death ligand 1 (PD-L1) and programmed cell death ligand 2 (PD-L2).

  • Datopotamab deruxtecanDrug

    Datopotamab deruxtecan (Dato-DXd) is a novel antibody-drug conjugate (ADC) composed of a humanized anti-TROP2 IgG1 monoclonal antibody linked to a topoisomerase I inhibitor payload and a cleavable linker.

  • CarboplatinDrug

    Carboplatin is a platinum compound chemotherapy used to treat lung cancer with a known safety profile. For more details on specific indications refer to the approved product label.

What is being measured

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

  1. Confirmed Intracranial Objective Response Rate (iORR) as Measured by the RANO-BM Criteria

    The intracranial objective response rate (iORR) is defined as the proportion of patients achieving a complete response (CR) or partial response (PR) according to the RANO-BM (Response Assessment in Neuro-Oncology Brain Metastases) criteria, as assessed by central review. The best overall CNS (central nervous system) response is determined based on a composite assessment of radiographical CNS target and non-target lesion responses, corticosteroid use, and clinical status.

    Measured: Through study primary completion, an average of 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pembrolizumab, Datopotamab deruxtecan and Carboplatin in people with Lung Cancer and Non Small Cell Lung Cancer, run by Latin American Cooperative Oncology Group at 13 sites in Brazil.

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 38 inclusion and 22 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: looking for participants now, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in Brazil. 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?

Contact Project Manager (+55 51 3384 5334, lacog0823@lacog.group), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Confirmed Intracranial Objective Response Rate (iORR) as Measured by the RANO-BM Criteria (time frame: Through study primary completion, an average of 2 years). 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 NCT06822543.

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 26 Aug 2026.
