Gossypol Combined With Docetaxel and Cisplatin Scheme in Advanced Non Small-cell Lung Cancers With APE1 High Expression

Phase 3
Conditions
Non-small Cell Lung Cancer
Interventions
Drug: Placebo
Registration Number
NCT01977209
Lead Sponsor
Third Military Medical University
Brief Summary

The investigators' experimental study found that gossypol was the natural inhibitor of apyrimidinic endonuclease 1 (APE1) and clinical study observed that high expression of APE1 was relative to the platinum-resistance in non-small cell lung cancer. Thus the purpose of this study is to find out whether gossypol can improve the sensitivity of cisplatin-based chemotherapy in the non-small cell lung cancer with apurinic apyrimidinic endonuclease 1 (APE1) high expression

  • At least one unidimensional measurable lesion meeting Response Evaluation Criteria in Solid Tumors (RECIST. 2000).
  • Patients can have the brain / meningeal metastasis history, but the metastasis must be treated by operation or radiotherapy), and clinically stable for at least 2 months.

If male, use of an approved contraceptive method during the study and 2 months afterwards.
