Clinical Trial on the Prevention of Thrombocytopenia After First-line Chemotherapy

Phase 2
Terminated
Conditions
Carcinoma, Non-Small-Cell Lung
Interventions
Registration Number
NCT01319669
Lead Sponsor
Chinese Society of Lung Cancer
Brief Summary

To assess the efficacy and safety of administration of rhTPO at different time in the treatment of thrombocytopenia caused by first-line GC/GP regimen for non small cell lung cancer (NSCLC)

Detailed Description

This is a randomized, controlled, open-labeled, multicenter clinical trial. The subjects are patients with NSCLC who are going to receive GC/GP regimen chemotherapy.

Vadhan-Raj et al conducted a study in which they administered rhTPO in various ways to patients with sarcoma receiving platinum-containing chemotherapy. The results demonstrated that timing of administration of rhTPO can be adjusted according to the occurrence time of nadir platelet values induced by chemotherapy. The timing of administration of rhTPO in this study was determined based on the above proofs.

GroupInterventionDescription
Treatment grouprecombinant human thrombopoietinrhTPO(recombinant human thrombopoietin) is given on the second, 4th and 9th day of the chemotherapy cycle in a dosage of 15000U once subcutaneously.
Control grouprecombinant human thrombopoietin15000U of rhTPO(recombinant human thrombopoietin) is given subcutaneously 6 to 24 hours within the end of chemotherapy cycle, that is, the 8th day for 3 consecutive days (d9 to d11)
Primary Outcome Measures
NameTimeMethod
minimum and maximum value of platelet count after chemotherapynine weeks

To evaluate the minimum and maximum value of platelet count after chemotherapy and the value of platelet count and their D-values comparing with the baseline values

Secondary Outcome Measures
NameTimeMethod
The duration when patient's platelet count remains below 50×109/Lnine weeks

The duration when patient's platelet count remains below 50×109/L, the time (in day) when patient's platelet count increases over 75×109/L and 100×109/L, the amount of platelet infused (number of units of apheresis platelet should be transformed into number of units of platelet concentrate)
