MOST Plus (My Own Specific Treatment) - A two-period, multicenter, randomized, open-label, phase II study evaluating the clinical benefit of a maintenance treatment targeting tumor molecular alterations in patients with progressive locally-advanced or metastatic solid tumors
EU CTIS ID: 2023-510566-27-00
What this study is testing
Induction period: To evaluate, the induction-Progression-Free Rate (PFR) after induction treatment with an Investigational Therapy in patients with progressive solid cancers of all histological types, after at least 1 prior systemic treatment regimen for advanced disease. Maintenance period: To compare the Progression-Free Survival (PFS) between arms (maintenance versus interruption of study treatment) for patients with stable disease (MTT cohorts) or objective response (IT cohort) after induction period.

(for olaparib, IT, nilotinib and pazopanib: AST and ALT ≤ 2.5x ULN; for pazopanib and nilotinib concomitant elevations in bilirubin and AST or ALT above 1x ULN and 1,5xULN respectively are not permitted) o Serum creatinine ≤ 1.5x ULN or creatinine clearance ≥ 50 mL/min (calculated by Cockcroft-Gault formula, or MDRD formula for patients older than 65 years) (for pazopanib: creatinine clearance ≥ 30 mL/min; for Olaparib: creatinine clearance calculated by Cockcroft-Gault formula ≥ 51 mL/min; for IT creatinine clearance > 40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance o For pazopanib: Urine Protein to Creatinine ratio (UPC) <1; if UPC ≥1, 24-hour urine protein must be <1g (use of urine dipstick for renal function assessment is not acceptable). o Corrected QT interval (QTcB) ≤ 450 msecs from 3 electrocardiograms (≤ 480 msecs if recommended MTT has no known effect on QT interval) on screening ECG, within 14 days prior to C1D1.

- Life expectancy of at least 4 months
- Histologically or cytologically confirmed diagnosis of metastatic or locally advanced and unresectable solid tumor of any type-except for Nilotinib cohort: only pigmented villonodular synovitis are eligible -, not amenable to curative treatment. Concerning primitive tumors of the central nervous system (CNS), all histological types of malignant tumors (including parenchymal and meningeal tumors) are eligible (CNS tumor are not eligible for the IT group)
- Documented disease progression at the time of study entry.
- At least one prior systemic treatment regimen for locally advanced or metastatic disease (chemotherapy, immunotherapy, targeted therapy, hormonotherapy; systemic treatment regimens given in the neoadjuvant or adjuvant setting and maintenance therapies will not be considered) - except for Nilotinib cohort (No previous treatment by immunotherapy is allowed for IT group). Patients who are candidates for a validated second line treatment regimen are not eligible for the study. For patients with a primitive CNS tumor, the absence of other therapeutic options must be validated by the reference committee for the patient’s pathology.
- Measurable disease, defined as at least one lesion that can be accurately measured on CT-scan or MRI (performed within 28 days prior to C1D1) according to RECIST 1.1. As there is no prior systemic treatment regimen available for locally advanced or metastatic PEComa, these tumors are eligible for a MTT treatment in first line of their advanced or metastatic disease.
- A multidisciplinary molecular board must have recommended one of the investigational MTT available in the study after review of a tumor or blood molecular profiling previously established from a biopsied lesion (preferably on a sample of the most recent progression) and/or primitive tumor (by NGS, Sanger sequencing, CGH or any other valuable technique) or from a liquid biopsy, respectively
- The MTT recommended by the multidisciplinary molecular board after the review of molecular profile is not approved and reimbursed in France for the disease affecting the patient in the same label.
