Combination therapy for advanced lung cancer with specific mutations

A Phase 2, Open-Label Study to Evaluate the Efficacy and Safety of ABSK043 Combined With Firmonertinib in Patients With EGFR Mutated Locally Advanced or Metastatic Non-small Cell Lung Cancer(NSCLC)

Phase 2 Interventional Abbisko Therapeutics Co, Ltd · NCT06668103

This study is testing a new combination of two drugs to see if they can help people with advanced lung cancer that has certain mutations feel better and live longer.

What this trial studies

This Phase 2 clinical study evaluates the safety and effectiveness of ABSK043 combined with Firmonertinib in patients with advanced non-small cell lung cancer (NSCLC) that has specific mutations in the epidermal growth factor receptor (EGFR). The study is divided into two parts: a dose escalation phase to determine the optimal dosage and a dose expansion phase to assess the treatment's efficacy as a first-line therapy. Participants will be closely monitored for safety throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are patients with locally advanced or metastatic NSCLC who have specific EGFR mutations and meet the study's inclusion criteria.

Not a fit: Patients who have not been diagnosed with EGFR mutations or those who have received prior systemic therapies for advanced disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with advanced lung cancer harboring EGFR mutations.

How similar studies have performed: Other studies have shown promise with similar combination therapies targeting EGFR mutations, indicating potential for success in this approach.

Inclusion Criteria:

1. Histologically or cytologically documented locally advanced or metastatic NSCLC
2. At least 1 measurable lesion as assessed by Investigator as per Response Evaluation Criteria in Solid Tumors (RECIST v1.1)
3.

4. Has unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0, Grade ≤1 or baseline.
5. Is receiving chronic systemic corticosteroids dosed at \>10 mg prednisone or equivalent anti-inflammatory activity or any form of immunosuppressive therapy.
6. Uncontrolled or significant cardiovascular disease
7. Has a known human immunodeficiency virus (HIV) infection that is not well controlled.
8. Any evidence of severe or uncontrolled diseases or other factors which in the Investigator's opinion makes it undesirable for the patients to participate in the study.
