What was measured

Will be assessed by Response Evaluation Criteria in Solid Tumors version 1.1. Response rates will be calculated as the percent of evaluable patients who are responders (Overall Best Response of Partial Response or Complete Response), and confidence intervals will be constructed accounting for the two-stage design.

Analysis population: All patients who met the evaluable for response criteria outlined in section 9.4 of the ADVL1622 protocol in non-osteosarcoma strata which were either statistical strata (Ewing's Sarcoma, Rhabdomyosarcoma, Non-Rhabdomyosarcoma Soft Tissue Sarcoma, and Rare Tumors) or accrued enough patients to be analyzed (Wilms Tumor). Data is limited for Rare tumors due to low accrual.

Groups in this outcome

Ewing's Sarcoma

Patients receive cabozantinib-s-malate (XL184), 40mg/m2/day orally (PO) on a continuous dosing schedule using a dosing nomogram on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Rhabdomyosarcoma

Patients receive cabozantinib-s-malate (XL184), 40mg/m2/day orally (PO) on a continuous dosing schedule using a dosing nomogram on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Non-Rhabdomyosarcoma Soft Tissue Sarcoma

Patients receive cabozantinib-s-malate (XL184), 40mg/m2/day orally (PO) on a continuous dosing schedule using a dosing nomogram on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Wilms Tumor

Patients receive cabozantinib-s-malate (XL184), 40mg/m2/day orally (PO) on a continuous dosing schedule using a dosing nomogram on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Rare Tumors

Patients receive cabozantinib-s-malate (XL184), 40mg/m2/day orally (PO) on a continuous dosing schedule using a dosing nomogram on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
