Patient case: 72-year-old male with lung adenocarcinoma; genetic feature: EZR-ROS1 fusion

Clinical trial: Efficacy and Safety of Maintenance Apatinib Combined With Pemetrexed in Advanced Non-squamous Non-small Cell Lung Cancer Patients

Summary: Lung cancer is a malignant tumor that causes the highest morbidity and mortality, and the main pathological type is non-small cell lung cancer (NSCLC). Most of them present with advanced stage at diagnosis. This design is to study maintenance therapy with pemetrexed plus apatinib after first line induction therapy four cycles for advanced non-squamous non-small-cell lung cancer.

  2. At least one measurable lesion
  3. If genetic testing (EGFR/ALK) is a sensitive EGFR mutation or ALK fusion gene positive, required for first line progress after targeted therapy;Without mutations, required for first-line treatment;
  4. Pemetrexed combined platinum did not progress by RECIST curative effect evaluation after 4 cycles of chemotherapy

  9. For women of child-bearing age, the pregnancy test results (serum or urine) within 7 days before enrolment must be negative. They will take appropriate methods for contraception during the study until the 8th week post the last administration of study drug.

  2. Genetic testing for sensitive EGFR mutation or ALK fusion gene is positive didn't accept targeted therapy
  3. Symptomatic brain metastases (Patients who have no symptoms and is not needed to receive therapy before 21 days may participate in this trial, but need to be confirmed by MRI\CT or venography that no hematencephalon symptom);
  4. Imaging (CT or MRI) shows that the tumor lesion vessels≤ 5 mm, or in the center of the large vessels tumor;Or show obvious lung empty or necrotic tumor;
  5. Uncontrolled hypertension(systolic pressure ≥ 140 mmHg and/or diastolic pressure ≥ 90 mm Hg) even though two or more than two hypotensive agents application.
  6. Patients who suffered from grade II or above myocardial ischemia or myocardial infarction, uncontrolled arrhythmias (including QT interval male ≥ 450 ms, female ≥ 470 ms).
