Phase II Trial of Vistusertib（AZD2014） Single Agent in TSC1or 2 Null or TSC 1/2 Mutation Solid Cancer Patients Refractory to Standard Chemotherapy

Phase 2

Withdrawn

• Conditions: Solid Tumor

• Registration Number: NCT03166176
• Lead Sponsor: Samsung Medical Center

Brief Summary

Patients with TSC1/2 mutated refractory solid cancer will receive vistusertib(AZD2014) monotherapy. Study-arm is composed of 27 patients. Vistusertib(AZD2014) 50mg BD continuous schedule of a 28 day cycle as a monotherapy

Detailed Description

Patients with TSC1/2 mutated refractory solid cancer will receive vistusertib(AZD2014) monotherapy. Study-arm is composed of 27 patients.

Vistusertib(AZD2014) 50mg BD continuous schedule of a 28 day cycle as a monotherapy Tumour evaluation using RECIST 1.1 will be conducted at screening (within 28 days prior to first dose) and every 8 weeks relative to the date of first dose, up to week 40, then every 16 weeks until objective disease progression (within a window of +/- 7 days of the scheduled date).

Study treatment will be continued until objective disease progression (unless other criteria for treatment discontinuation are met). Patients may continue vistusertib(AZD2014) beyond progression (according to RECIST 1.1), at the discretion of the investigator if they are clinically benefiting from the treatment and they do not meet any other discontinuation criteria.

If a patient discontinues study treatment prior to disease progression, they should continue to be assessed using RECIST 1.1 until disease progression and then followed up for survival.
