Study of TAK-228 (MLN0128) in Soft Tissue Sarcomas

Study Summary

This is an open-label phase II study of TAK-228 for patients ≥ 18 years of age with complex genomic sarcomas exhibiting Phosphoinositide-3 Kinase (PI3K) pathway dysregulation. Patients must have surgically unresectable or metastatic disease that is refractory to at least one prior line of therapy (not including neoadjuvant or adjuvant therapy in a curative setting). Patients disease must also have evidence of progression prior to enrollment. The purpose of this study is to determine the antitumor activity in this group of patients. Patients must meet all eligibility criteria as detailed in section 10. A total of up to 33 patients will be included in the study. Patients will undergo screening evaluations to determine eligibility within 28 days of the first dose. All patients will be required to submit baseline tumor samples for analysis. Patients who have had their tumors tested commercially for PI3K/ AKT/mechanistic Target of Rapamycin (mTOR) alterations will be assessed on a case by case basis for eligibility and for determination as to whether additional tissue is required. TAK-228 will be administered orally at 3 mg daily for a 21 day cycle. Clinical and laboratory assessments will be made on day 1 of each cycle. Disease will be assessed by comparing unidimensional tumor measurements on pre and peritreatment imaging (CT or MRI) after weeks 6, 12, 18 and every 12 weeks thereafter. Response will be assessed according to RECIST 1.1. Therapy will continue until disease progression or unacceptable toxicity or withdrawal of consent.

Primary Outcome

Progression free rate will be determined by determining the number of patients with complete response, partial response and stable disease
