About this study

Official title: A Phase 1, Open-Label Study of ABSK112 to Assess Safety, Tolerability, and Pharmacokinetics in Patients With Non-Small Cell Lung Cancer

This is a first-in-human (FIH), multicenter, non-randomized, openlabel, phase 1 study of ABSK112 in patients with NSCLC to evaluate the safety, tolerability, PK, and preliminary antitumor efficacy.

Read the detailed description

The study will be started with a dose escalation part of ABSK112 administered in repeated 28-day cycles in patients with NSCLC. The expansion part of oral ABSK112 at the recommended dose of expansion (RDE) will be followed to evaluate safety, tolerability, and preliminary antitumor activity among patients with locally advanced or metastatic NSCLC harboring EGFR Exon20ins.

Being tested
ABSK112
Medical subject headings
Carcinoma, Non-Small-Cell Lung

What participants receive

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

  • ABSK112Drug

    Also called EGFR Exon20 inhibitor

    In the escalation part, patients will receive a single dose of oral ABSK112 on Cycle1 Day1 only, and then patients will continuously receive ABSK112 once daily (QD) or twice daily (BID) in subsequent cycles. In the expansion part, patients will each be treated at the selected RDE dose level.

Study groups in NCT06225804
Study groupRoleWhat they receive
ABSK112ExperimentalDuring the escalation part, the administration of oral ABSK112 will be guided by Bayesian optimal interval (BOIN) design based on safety data collected until a maximum tolerated dose (MTD) has been identified. The first dose level will be administered as QD, and different dosing frequencies (e.g., BID) may be explored in subsequent doses depending on emerging safety and pharmacokinetic data. A separate food effect cohort may be conducted. In expansion part, patients will be treated at the selected RDE dose level.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ABSK112 in people with Non-Small Cell Lung Cancer, run by Abbisko Therapeutics Co, Ltd at 14 sites in 2 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 17 inclusion and 23 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 26 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in China, 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?

Incidence of DLT (time frame: from Day1 to Day28). The study lists 4 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 26 Oct 2026.
