A Phase 2 Clinical Study of Combination Therapy With ABSK043 and Firmonertinib

Официальное название

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)

Обзор

This is an open-label phase 2 study to evaluate the safety, tolerability and preliminary anti-tumour activity of ABSK043 in combination with Firmonertinib in patients with Epidermal Growth Factor Receptor-mutated (EGFRm+) locally advanced or metastatic NSCLC.

Подробное описание

This is a Phase II, open-label, multicentre study of ABSK043 administered orally in combination with Firmonertinib to patients with EGFRm+ advanced NSCLC. The study has been designed to allow an investigation of the optimal combination dose and schedule whilst ensuring the safety of patients with intensive safety monitoring. There are two main parts to this study; Part A, dose escalation and Parts B Dose expansion. The expansion part will evaluate the efficacy of ABSK043 in combination with Firmonertinib as first-line treatment for locally advanced or metastatic NSCLC patients with EGFR-mutated at the one or more recommended dose.

Dose escalation:

• Post-line: Patients with locally advanced or metastatic NSCLC with an EGFR exon 19 deletion or L858R mutation with tumor progression after treatment with systemic treatment

Dose Expansion:

• First-Line: Patients with locally advanced or metastatic NSCLC with an EGFR exon 19 deletion or L858R mutation, and without prior systemic therapy for advanced or metastatic disease.

Вмешательства

• Препарат ABSK043 in combination with Firmonertinib
  Two potential dose levels ：400 mg twice daily （BID） and 800 mg BID) of ABSK043 are prespecified and firmonertinib will be administered orally at a fixed dose of 80 mg once daily (QD). Patients in dose escalation cohort will receive the ABSK043, 400 mg BID and firmonertinib 80 mg QD as the starting dose for the combination therapy. Patients in dose confirmation cohort and dose expansion cohort will receive the recommended dose in dose escalation cohort and be evaluated for safety and preliminar
