Clinical Trial Summary

The aim of this study is to evaluate the efficacy and safety of Second-line chemotherapy combined with Apatinib for the patients with resectable pulmonary metastasis of osteosarcoma.

Description:

After standard chemotherapy and surgery for the localized disease, pulmonary metastases of osteosarcoma occurs in up to 40% of cases and still remain challenging without satisfactory regimen. Apatinib is a oral kinase inhibitor of receptor tyrosine targeting VEGFR2. A pilot study indicated that Apatinib improved the PFS after multi-line chemotherapy failure, and might partly reversed chemo-refractory status for advanced osteosarcoma. Thus, the investigators explored the efficacy of combining Apatinib with current available second-line chemotherapy compared to chemotherapy alone for treating first resectable pulmonary metastases of osteosarcoma following the failure of first-line chemotherapy and wide/radical-margin surgery. Participants will receive 250 mg of apatinib twice daily combined with gemcitabine-docetaxel (GD) regimen before and after the surgical resection of the pulmonary metastases. Osteosarcoma patients with pulmonary recurrence only at baseline will be recruited in the study. The primary end point is progression-free survival rate (PFR) compared with historical control. A12 month PFR of 30% or less is considered inactive, while a 12 month PFR of 50% or greater is regarded as of interest for additional development. With a type I error rate of 5% and a power of 83%, the number of patients needed for this design is 43.

• normal or controlled blood pressure;

• no thoracic comorbidities with adequate pulmonary function eligible for thoracic surgery

Exclusion Criteria:

• previously exposed to GD chemotherapy or VEGFR2 Tyrosine-kinase inhibitors (TKIs);

• existence of local recurrence;

• have had other kinds of malignant tumors at the same time;

• cardiac insufficiency or arrhythmia;

• uncontrolled complications, such as diabetes mellitus and so on;

• coagulation disorders or Hemorrhagic diseases ;

• metastases considered unresectable or borderline resectable at baseline

• intolerable of thoracis surgery

• pleural or peritoneal effusion that needs to be handled by surgical treatment;

• combined with other infections or wounds

• wound dystrophy, poor soft-tissue around implantation or other wound complications risky of non-healing given angiogenesis inhibitor assessed by the investigators

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Exploratory outcome: Subgroup analysis of progression-free survival(PFS)	The PFS for each subgroups in terms of clinicopathological characteristics (age, gender, histological type, solitary or multiple metastases, unilateral or bilateral metastases, early or late metastases, calcifying or non-calcifying lesions, with or without lesion cavitation, with or without AEs [especially pneumothorax, hand-foot skin reactions, hair depigmentation], etc)	Baseline until disease progression or death, whichever occurs first (followed through study completion, an average of 1.5 years)
Other	Exploratory outcome: The correlation of potential pathological biomarker with PFS	The correlation between the expression of VEGFR2, CD34, Ki-67 and immune cell infiltration by immunohistochemistry and PFS	Baseline until disease progression or death, whichever occurs first (followed through study completion, an average of 1.5 years)
Other	Exploratory outcome: Tumor response pre-metastasectomy as a predictor of PFS	to compare the PFS of the three group according to tumor response pre-metastasectomy (group1: CR/PR, group2: SD, group3 PD)	Baseline until disease progression or death, whichever occurs first (followed through study completion, an average of 1.5 years)
Other	Exploratory outcome: Tumor cavitation as a prognostic factor for oncological outcome	to compare the predictive value of the Crabb's modified RECIST criteria with the original RECIST 1.1 criteria in terms of PFS and OS	Baseline until disease progression or death, whichever occurs first (followed through study completion, an average of 1.5 years)
Other	Exploratory outcome: AEs of the targeted therapy as prognostic factors for oncological outcome, especially pulmonary lesion cavitation/pneumothorax and hair depigmentation	to correlate the incidence of targeted therapy related AEs (especially pneumothorax, hand foot skin reactions, skin and hair depigmentation and fatigue)with the PFS/OS for the treatment arm.
