The Global objective of this Basket of Basket study is to evaluate the antitumor activity of each matched therapies that will be evaluated through the study in small molecularly selected populations.
The objective of module 1 will be to determine the overall response rate by RECIST 1.1 of atezolizumab in several arms. Subjects will be separated into arms depending on the mutations of their tumour. All patients in genomically selected populations will receive atezolizumab 1200 mg IV every 3 weeks

|Advanced Solid Tumor||Drug: Arm 1 - atezolizumab||Phase 2|
Basket studies are a new sort of clinical studies to identify patients with the same kind of mutations and treat them with the same drug, irrespective of their specific cancer type. In basket studies, depending on the mutation types, patients are classified into "baskets". Targeted therapies that block that mutation are then identified and assigned to baskets where patients are treated accordingly.
This protocol has two parts: part A (iPROFILER), which includes the common procedures for tumor molecular profiling and treatment recommendation, and part B (iBASKET), which corresponds to the therapeutic portion The purpose of part A (iPROFILER) of this study is to test participants' tumour tissue in order to identify whether their tumour has certain mutations in cancer-related genes. It is known that gene mutations of tumours contribute to their origin and growth and determine whether the tumour will respond to particular cancer drugs. This test will provide information about potential targeted therapies that specifically attack those gene mutations. The purpose of part B (iBASKET) of this study is to offer participants a personalised anti-cancer treatment based on the gene mutations that are found in their tumour. Participants taking part in this module 1 of part B (iBASKET), in genomically selected populations, will receive atezolizumab 1200mg intravenously every 3 weeks, following the analysis of their tumour in part A (iPROFILER). Participants will be able to take atezolizumab for as long as their tumour doesn't grow and for as long as they don't have any side-effects which prevent them from continuing treatment.
The study will have a 2-year recruitment period. The aim of the study is to determine which genomically selected populations respond effectively to the targeted treatment, atezolizumab. Approximately 1000 participants will be enrolled into part A (iPROFILER), with approximately 100 participants being recruited into module 1 of part B (iBASKET)."

|Official Title:||Basket of Baskets: A Modular, Open-label, Phase II, Multicentre Study To Evaluate Targeted Agents in Molecularly Selected Populations With Advanced Solid Tumours|
|Actual Study Start Date :||December 10, 2018|
|Estimated Primary Completion Date :||May 2022|
|Estimated Study Completion Date :||November 2022|
Experimental: Module 1 Arm 1 - atezolizumab
Genomically selected populations will all receive the same drug (6 groups of mutation will be evaluated)
Subjects will be recruited and allocated to arms according to their biomarker profile. It is assumed that 1000 subjects will need to be screened in part A in order to enroll 100 patients in part B of module 1.
Drug: Arm 1 - atezolizumab
Module 1 - 1200mg, IV, every 3 weeks, until progression or unacceptable toxicity develops.
- Overall response rate by RECIST 1.1 [ Time Frame: 12 weeks ]For the purposes of the primary endpoint of this study, subjects will be evaluated for response and progression using the new international criteria proposed by the revised RECIST guideline (version 1.1). Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in the RECIST criteria The best overall response is the best response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started). The patient's best response assignment will depend on the achievement of both measurement and confirmation criteria.
- Mean progression free survival (PFS by RECIST 1.1) of the subjects participating in iBASKET [ Time Frame: through study completion, an average of 3 years. ]
- Progression Free Survival (PFS by RECIST 1.1) [ Time Frame: 6 months. ]
- Mean overall survival of subjects treated with targeted therapy in iBASKET [ Time Frame: through study completion, an average of 3 years. ]
