A Study of Pemetrexed Plus Cisplatin in Patients With Refractory Soft Tissue Sarcoma

Phase II Study of Pemetrexed Plus Cisplatin in Patients With Refractory Soft Tissue Sarcoma

The yearly incidence of soft-tissue sarcomas(STS) in the USA is roughly 11,280 cases, and metastatic STS have a median overall survival of about 12 months. After the standard 1st line chemotherapy with doxorubicin, the only a few treatment option is available. Recently, pemetrexed, a novel multitargeted antifolate, has shown modest activity as a single agent lung cancer and mesothelioma. In patients with refractory STS, pemetrexed is well tolerated and moderately effective. Based on the background, investigators planned to conduct the phase II trial of pemetrexed in combination with cisplatin for metastatic/recurred soft-tissue sarcomas.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: pemetrexed+cisplatin; Patients with metastatic sarcoma who underwent one chemotherapy regimens are treated with the combination of pemetrexed and cisplatin, and the treatment is repeated until the disease progression. pemetrexed 500 mg / m2 (day 1) and cisplatin 75 mg / m2 (day 1) are intravenously injected. 21 days is one cycle, and it is carried out by co-administration up to 6 cycles. After 7 cycles, intravenous injection of pemetrexed alone at intervals of 3 weeks until disease progression.

Drug: Pemetrexed, cisplatin; Pemetrexed 500mg/m2, Intravenous, Q 3weeks. Cisplatin 75mg/m2, Intravenous, Q 3weeks. Combination administration : up to 6cycles After 6 cycle, pemetrexed alone is administered.
