What is being measured

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

  1. Safety and tolerability

    Dose-limiting toxicity (DLT); Incidence and severity of adverse events (AEs); Discontinuation of study treatment due to AEs

    Measured: From subject sign the informed consent form (ICF) to 30 days after the last dose of study treatment, up to approximately 36 months

  2. ORR

    Objective response rate (ORR) per RECIST v1.1

    Measured: The proportion of subjects with a confirmed complete response (CR) or partial response (PR), up to approximately 36 months

Secondary outcomes (3)
  1. Duration of response (DOR)

    For subjects with a confirmed CR or PR, DOR is defined as the time from the first documented evidence of CR or PR until radiographic disease progression or death due to any cause, whichever occurs first

    Measured: From baseline until disease progression, death, or other protocol defined reason, up to approximately 36 months

  2. Progression-free survival (PFS)

    The time from first dose of study intervention to first documentation of radiographic disease progression or death due to any cause, whichever occurs first

    Measured: From baseline until disease progression, death, or other protocol defined reason, up to approximately 36 months

  3. Overall survival (OS)

    the time period from the start of study intervention to death due to any cause.

    Measured: From baseline until death due to any cause, up to approximately 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SKB264, Pembrolizumab and Carboplatin in people with Non-small Cell Lung Cancer, run by Klus Pharma Inc. at 50 sites in 6 countries.

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 12 inclusion and 17 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 27 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 50 sites in China, Spain, South Korea, Turkey (Türkiye), Georgia and 1 more country. 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?

Safety and tolerability (time frame: From subject sign the informed consent form (ICF) to 30 days after the last dose of study treatment, up to approximately 36 months). 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 27 Jan 2026.
