Phase II Study of Pemetrexed in Advanced or Recurrent Gastric Cancer After Chemotherapy

Phase 2

Completed

• Conditions: Gastric Cancer
• Interventions: Drug: Pemetrexed disodium

• Registration Number: NCT01953419
• Lead Sponsor: Sun Yat-sen University

Brief Summary

This phase II trial aimed to assess the efficacy and safety of pemetrexed in patients with pretreated metastatic gastric cancer.

Detailed Description

Patients enrolled in this study received pemetrexed 500mg/m2, once every 21 days, until the presence of progressive disease or unacceptable toxicity. All patients took dexamethasone 3.75 mg twice daily, starting from the day before and continuing to the day after the drug administration. Patients were instructed to take oral folic acid 400 mg daily beginning 5 days before the first therapy and until the final therapy.Patients received Vitamin B12 very 3 cycle of chemoherapy. Granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF) or Erythropoietin (EPO) was not allowed, but they could be used when the patients suffered from bone marrow depression.
