Experiment 1 Reporting the Activity Data of This PDC [1]
Indication Hepatocellular carcinoma
Efficacy Data Time to disease progression
134 Day
Patients Enrolled
Patients with hepatocellular carcinoma who progressed on or after treatment with sorafenib or intolerant of sorafenib.
Administration Time Days 1, 2, and 3 of a 28-day cycle
Administration Dosage 40 mg/m2
Description
The median TTP was 134.0 days, median PFS was 129.0 days, and median OS was 205.0 days.
Experiment 2 Reporting the Activity Data of This PDC [2]
Indication Non-small cell lung cancer
Efficacy Data Progression-free survival (PFS)
52 day
Patients Enrolled
Patients with non-small cell lung cancer.
Administration Time Day 1/2/3
Administration Dosage Dose level ( mg/m2) 10
Description
Among the 42 patients considered to be evaluable for efficacy, there were no observations of objective response. However, 12 (28.6%) of patients had disease stabilisation. Overall, PFS was a median of 52.0 days (n1/442; censored 8; Q1, Q3: 50.0, 112.0). However, among the 12 patients with SD as best response, progression-free survival (PFS) was considerably higher: 129 days with 8 patients censored at the date of last study visit (Table 5A). Among the 16 efficacy-evaluable patients enrolled in part 2, 5 patients presented to the study with a diagnosis of hepatocellular carcinoma and had progressed on or were intolerant of sorafenib. In these 5 patients, prolonged disease stabilisation with an average PFS of 166 days (6 months) was observed (Table 5B); in patients with HCC who received more than 2 cycles of treatment, the PFS was 209 days, approaching 7.5 months
