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

October 30, 2013 updated by: Dong Wang, Third Military Medical University

A Randomized, Double Blind, Placebo-controlled Multiple-center Phase III Trial of Gossypol Combined With Docetaxel and Cisplatin Scheme in Advanced Non Small-cell Lung Cancers With APE1 High Expression

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

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

the first day of treatment to the date that disease progression is reported; assesed up to 4 years

Secondary Outcome Measures

Secondary Outcome Measures

Time Frame
Overall survival
Time Frame: the first day of treatment to death or last survival confirm date; assesed up to 4 years
the first day of treatment to death or last survival confirm date; assesed up to 4 years
Tumor response rate
