Summary

The MOST Plus study is a two-period phase II clinical trial, conducted in patients with all types of progressive solid tumors after at least 1 prior systemic treatment regimen for advanced disease (in the absence of a validated second line therapy). The main goal of this study is to evaluate for these patients the clinical benefit of a maintenance treatment in patients with stable disease (SD) after induction treatment with a selected therapy (Molecular Targeted Therapy (MTT) or with SD, partial response (PR) or complete reponse (CR) with Immunotherapy (IT)). For MTT, the first period of this trial (induction period) will enable to establish whether the identification of genomic alterations in genes encoding for "actionable" targets in the tumor cells, regardless of the histological subtype, can be used to select efficient treatment targeting the pathway activated by the mutation. For Immunotherapy, induction period with durvalumab + tremelimumab is expected to be an innovative therapy for an efficient tumor control and may allow to identify types of cancer or molecular types of cancer that are more receptive to immunotherapy. For all treatments, the second period (maintenance period) will use a randomized design to evaluate the clinical benefit of a maintenance treatment with the targeted therapy or immunotherapy selected based on tumor molecular profile in patients treated by MTT with SD and in patients treated by IT with SD, PR or CR. Each patient enrolled will receive the matching targeted therapy during 12 weeks (MTT) or 52 weeks (IT). At the end of this induction period: MTT cohorts : * patients with a tumor response (CR: complete response or PR: partial response) will continue the targeted therapy, * patients in progression will discontinue the targeted therapy and will be withdrawn from study and oriented towards standard treatments * patients with a stable disease at 12 weeks will be randomized in order to determine if they continue or stop the therapy. IT cohort : \- patients with SD, PR or CR at 52 weeks will be randomized in order to determine if they continue or stop the therapy. For each MTT treatment group: \~80 patients treated in the first step (induction period), 50 patients randomized in the second step (maintenance period, 25 patients per arm). For IT treatment group: \~125 patients treated in the first step (induction period), 50 patients randomized in the second step (maintenance period, 25 patients per arm). In total (for 7 treatment groups): \~ 900 patients treated in the induction period and 350 patients randomized in maintenance period.

Interventions

DRUG

Nilotinib (400 mg BID)

Patient with advanced pigmented villonodular synovitis and tumors with mutations of ABL1, KIT, PDGFRA, PDGFRB, DDR1, DDR2, CSF1R, or amplification/translocation of the genes and/or of the ligands.

DRUG

Everolimus (10 mg QD)

Patients whose tumor harbors mutations or amplification of the PIK3CA, PIK3R1, AKT1, AKT2, mTOR, RICTOR, RAPTOR genes, or with TSC1, TSC2 or PTEN loss (defined as complete loss of both gene copies OR loss of one copy + mutation on the other copy or loss of one copy + loss of expression using immunohistochemistry).

DRUG

Sorafenib (400 mg BID)

Patients whose tumor harbors mutations of VEGFR1-3, PDGFRB, FLT3, BRAF (other than V600 mutations), CRAF, HRAS, KRAS or RET or amplification/translocation of the genes and/or of the ligands.

DRUG

Lapatinib (1500 mg QD)

Patients whose tumor harbors mutations or amplifications of HER2

DRUG

Pazopanib (800 mg QD)

Patients whose tumor harbors mutations of VEGFR1-3, PDGFRA, PDGFRB or KIT\* or amplification /translocation of the genes and/or of the ligands.

DRUG

Olaparib (300 mg BID)

ATM, BAP1 et BRIP1 Mutation only if double hit documented; BRCA2, BRCA1, RAD51C, PALB2, RAD51D Mutation; BRCA1, BRCA2, ATM and BAP1 Loss; BRCA1, BRCA2, ATM and BAP 1 : mutation and heterozygote deletion. except for patients eligible to olaparib's available labels and reimbursements in France. NOTE : only prostate cancer with RECIST 1.1 evaluable disease are eligible until the French price and reimbursement

COMBINATION_PRODUCT

Durvalumab + Tremelimumab

Any molecular types of tumor (which are known to be immunogenic or with high mutation load), except lung, urothelial and head and neck or CNS tumors, or patients who fulfill conditions to receive any other MTT of the MOST Plus study.
