A Modular Multi-Basket Trial to Improve Personalized Medicine in Cancer Patients (Basket of Baskets)

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 module 1 of part B (iBASKET) will receive atezolizumab 1200 mg IV 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. Module 1 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 120 participants being recruited into module 1 of part B (iBASKET).

Participants taking part in module 2 of part B (iBASKET) will receive will receive futibatinib, 20 mg, once daily (QD) in 28-day cycles, following the analysis of their tumour in part A (iPROFILER). Participants will be able to take futibatinib 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. Module 2 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, futibatinib. Approximately 1000 participants will be enrolled into part A (iPROFILER), with approximately 80 participants being recruited into module 2 of part B (iBASKET).

Participants taking part in module 3 of part B (iBASKET) will receive amivantamab 1050 mg IV for body weight < 80 kg and 1400 mg for body weight >= 80 kg mg once weekly in Cycle 1 (with a split dose on Days 1-2) and then every 2 weeks in subsequent cycles (28-day cycles), following the analysis of their tumour in part A (iPROFILER). Participants will be able to take amivantamab 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. Module 3 will have a 2.5-year recruitment period. The aim of the study is to determine which genomically selected populations respond effectively to the targeted treatment, amivantamab. Approximately 1725 participants will be enrolled into part A (iPROFILER), with approximately 69 participants being recruited into module 3 of part B (iBASKET).

Eligibilty Criteria (PART A - iPROFILER)

Inclusion criteria

• Subjects must have histologically or cytologically confirmed malignancy that is metastatic or unresectable, who have progressed to standard therapy, who are receiving a standard anticancer treatment, but no subsequent approved treatment would be available upon progression, who are unable to receive standard therapy, or for whom standard therapy does not exist.
• Patient must have ECOG performance status of 0 or 1.
• Subjects must be 18-year-old or older.
• Subjects must have measurable disease according to RECIST 1.1.
• Subjects must have enough tumour tissue for molecular analysis.

• Subjects providing formalin-fixed paraffin embedded tissue (FFPE) must provide a minimum amount of tissue ranging from 28 to 36 slides depending on the sample tumour cellularity. If there is not enough archival tissue to meet this criterion, the patient must undergo a tumour biopsy.
• Subjects providing fresh frozen tissue must provide 5 core biopsies or equivalent.

Fresh frozen tissue must be preferentially collected from a tumour biopsy; hence, subjects must have disease amenable to be biopsied. Otherwise, the patient should have fresh frozen tumour tissue stored in a biobank or biorepository.

• Efforts will be made to provide fresh frozen tissue in at least one quarter of the participating subjects. The proportion of subjects that might provide fresh frozen tissue might change based on the results from the molecular analysis.
• Since some of the tests are performed in FFPE tissue, subjects providing fresh frozen tissue from a recent biopsy will have part of the sample processed in FFPE as per Laboratory manual.
• Subjects must have adequate haematological, renal, and hepatic function.
• For subjects requiring a tumour biopsy: subjects must have adequate coagulation function.
• Subjects must be willing to participate in a clinical trial with a matched therapy according to the molecular profile of his/her tumour.

Exclusion criteria

• Subjects with leptomeningeal disease should be excluded from this clinical trial.
• Subjects with known unstable brain metastases should be excluded from this clinical trial. Exception: Subjects who have undergone surgery and/or radiotherapy and in which brain metastases remain stable or decrease in size for six months after having completed therapy.
• Subjects with spinal cord compression not definitively treated with surgery and/or radiation.
• Subjects with uncontrolled intercurrent illness including, but not limited to, active infection, symptomatic congestive heart failure, LVEF < 50%, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
