Comparing D-1553 Tablet to Docetaxel Injection for Advanced Lung Cancer

A Randomized, Controlled, Double-blind, Double-simulated, Multicenter Phase III Clinical Study Evaluating D-1553 Tablet Versus Docetaxel Injection for KRAS G12C Mutation-positive Locally Advanced or Metastatic Non-small Cell Lung Cancer After Prior Standard Therapy Failure.

Phase 3 Interventional Chia Tai Tianqing Pharmaceutical Group Co., Ltd. · NCT06300177

This study is testing if a new tablet called D-1553 works better than the standard Docetaxel injection for patients with advanced lung cancer who have a specific genetic mutation and haven't had success with other treatments.

What this trial studies

This clinical trial evaluates the effectiveness of D-1553 Tablet compared to Docetaxel Injection in patients with KRAS G12C mutation-positive non-small cell lung cancer (NSCLC) who have experienced failure of prior standard therapies. The primary focus is on measuring progression-free survival (PFS) as assessed by an Independent Review Committee using RECIST 1.1 criteria. Participants must provide tumor tissue samples for mutation confirmation and meet specific eligibility criteria, including performance status and expected survival. The study aims to determine if D-1553 can offer a better treatment option for this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with KRAS G12C mutation-positive locally advanced or metastatic NSCLC who have failed prior standard therapies.

Not a fit: Patients with other types of lung cancer or those who have not experienced treatment failure with first-line therapies 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 who have limited treatment choices.

How similar studies have performed: Other studies targeting KRAS mutations have shown promise, but this specific approach with D-1553 is relatively novel.
