A phase I/II study was performed to assess the efficacy and toxicity of a new oral taxane in patients with recurrent, advanced Non-small Cell Lung Cancer.


Patients who were treated with one prior, taxane free chemotherapy regimen, were eligible for this study. A single oral dose of DJ-927 (27 mg/m) was given every 3 weeks. In case of good tolerance, one dose escalation to 35 mg/m was allowed. Response and toxicity were measured and plasma pharmacokinetic analysis was performed during the first course.


From October 2004 to September 2005, 36 patients gave informed consent and 34 received medication. The mean age was 58 years (range, 33-75 years). The majority of patients were pretreated with a combination of cisplatin and gemcitabine. Median interval between end of first treatment and the registration of this study was 7 months (range, 0.8-22 months). Twelve patients died on study of which eight due to disease progression. In four patients with preexisting cardiac disease, toxicity led to cardiac worsening and subsequent death. Grade 3 and 4 toxicities according to the National Cancer Institute Common Toxicity Criteria were neutropenia in 18 patients (53%), anemia in six patients (18%), nausea and fatigue in two patients (6%), febrile neutropenia and neurotoxicity in one patient (3%). The overall response rate for all patients was 5.6% (Confidence Interval [CI] 0.7-18.7%). The percentage of patients with stabilization for >6 weeks was 47%. The median time to progression was 97 days (CI: 47-167 days) and the median survival time was 120 days (CI: 68-222 days) for the ITT group. Since only a minority of patients (3) tolerated the higher drug dose we omitted this dose level because of hematological toxicity. Pharmacokinetic analysis showed that the median area under the curve (t = 0-168 hours) was 1752 +/- 1355 ngr/ml/h and the half-life was 167 +/- 77 hours.


When administered once every 3 weeks, this oral taxane formulation of DJ-927 was well-absorbed with a long terminal half-life of 167 +/- 77 hour. DJ-927 has antitumor activity against Non-small Cell Lung Cancer when given as second-line monotherapy (overall response rate in 5.6%; CI 0.7-18.7%). Ten patients experienced SD for more than 8 weeks. Different types of dose administration (metronomic dosing) or combination with other cytotoxic agents should be considered in future studies.
