Gedetailleerde beschrijving

This is an open-label study with an escalation part and an expansion part. The dose escalation part will evaluate the safety, tolerability of ABSK043 in combination with Osimertinib in previously treated participants with EGFR-mutated and PD-L1 positive locally advanced or metastatic NSCLC. The expansion part will evaluate the efficacy of ABSK043 in combination with Osimertinib as first-line treatment for participants with EGFR-mutated and PD-L1 positive locally advanced or metastatic NSCLC at the one or more recommended dose(s). The safety, tolerability, and PK profile of ABSK043 in combination with Osimertinib will also be further evaluated.

Escalation Part:

The escalation part includes dose escalation cohorts and backfill cohort(s), enrolling a sufficient number with previously treated participants with EGFR-mutated and PD-L1 positive locally advanced or metastatic NSCLC.

Expansion Part:

The expansion part will enroll a sufficient number with treatment-naïve participants with locally advanced or metastatic NSCLC harboring the EGFR mutation and PD-L1 positive expression.

    2. Participants must have received ≥2 prior lines of frontline systemic therapy.
    3. Documented or central laboratory test report confirms that the tumor is PD-L1 expression positive (TPS/TC≥1%).
    4. Documented genetic testing report confirms the presence of EGFR alteration(s) in tumor or plasma.

    Expansion cohort(s):

Experimenteel: ABSK043 in combination with Osimertinib
This is an open-label phase 2 study with an escalation part and an expansion part.
Geneesmiddel: ABSK043 in combination with Osimertinib

Three potential dose levels of ABSK043 are prespecified, and Osimertinib will be administered orally at a fixed dose of 80 mg QD in escalation cohort.

Patients in dose confirmation cohort and dose expansion cohort will receive the recommended dose in dose escalation cohort and be evaluated for safety and preliminary anti-tumor activity of the combination therapy.
