Details and patient eligibility

About

The primary objectives of this study are:

To evaluate the efficacy of glufosfamide in subjects with extensive recurrent sensitive small cell lung cancer (SCLC) as measured by objective response rate
To evaluate the safety of glufosfamide in subjects with extensive recurrent sensitive SCLC

The secondary objectives are:

To evaluate the efficacy of glufosfamide in subjects with extensive recurrent sensitive SCLC as measured by duration of response, progression-free survival and overall survival
To evaluate the pharmacokinetics of glufosfamide and isophosphoramide mustard (IPM)

The exploratory objectives of this trial are:

To evaluate the effect of glufosfamide on lung cancer symptoms
To evaluate the role of tumor cell glucose transporter expression on the efficacy of glufosfamide
