Clinical Research Directory

Inclusion Criteria: 1. Population: Male or female patients aged ≥18 years. 2. Diagnosis: Histologically or cytologically confirmed advanced lung adenocarcinoma. 3. Molecular Status: Documentation of ALK rearrangement confirmed by a validated test (e.g., NGS, IHC, FISH). 4. Prior Therapy: Prior treatment with lorlatinib (in any line of therapy), with documented disease progression or intolerance. 5. Current Therapy: Initiated treatment with iruplinalkib in the real-world setting. 6. Measurability: Presence of at least one evaluable lesion (measurable or non-measurable) for response assessment. 7. Data Availability: availability of key clinical data (baseline characteristics, treatment history, and follow-up outcomes). Exclusion Criteria: 1. Lack of Exposure: Patients who never actually received iruplinalkib or took only a trivial amount (e.g., \< 1 week/cycle) before withdrawal for non-medical reasons. 2. Wrong Diagnosis: Active malignancy of other histological types (excluding treated basal cell carcinoma, etc.). 3. Confounding: Participation in another interventional clinical trial involving an investigational anti-tumor drug concurrently. 4. Pregnancy: Pregnant or breastfeeding women. 5. Data Quality: Missing critical medical records that preclude assessment of primary endpoints (e.g., unknown start date, unknown prior therapy).
