This trial is a multicenter, open-label, biology driven, phase II study using a
sequential Bayesian design, aiming to assess the efficacy and safety of different Matched
Targeted Therapy (MTT) in independent and parallel cohorts of treatment.
Patients will be assigned to a treatment cohort based on molecular
alterations/characteristics detected on tumor sample from primary tumor or metastatic
lesion.
In this protocol, several MTTs treatment cohorts are planned. This study is designed with
the flexibility to open new MTTs treatment cohorts and to close existing MTTs treatment
cohorts that demonstrate no clinical benefit. Each treatment cohort will be driven
separately even though procedures, quality control and reporting, will be common. The
protocol will be amended in order to include new treatments or combinations that emerge
as being of interest for patients with advanced/metastatic cancers.
All eligible patients will receive study drugs as long as patient experiences clinical
benefit in the opinion of the investigator, or until unacceptable toxicity, or until
symptomatic deterioration attributed to disease progression as determined by the
investigator after an integrated assessment of radiographic data and clinical status, or
withdrawal of consent.
Patients will be permitted to continue study treatment after progressive disease
according to RECIST v1.1 if they meet all of the following criteria and following
validation of the Sponsor:
- Evidence of clinical benefit as assessed by the investigators,
- Absence of symptoms and signs (including worsening of laboratory values; e.g., new
or worsening hypercalcemia) that indicate unequivocal progression of disease,
- No decline in ECOG Performance Status (PS) that can be attributed to disease
progression.

Critères
Tous
- Male or female patients aged of at least 18 years on day of signing informed
consent.
- Patients with histologically confirmed diagnosis of metastatic disease or
unresectable locally advanced malignancy that is resistant or refractory to standard
therapies or for which standard therapies does not exist or is/are not considered
appropriate by the investigator.
- A multidisciplinary molecular board must have recommended the specific MTT based on
the following documented actionable alterations:
- Cohort HDM201-Ribociclib : amplification of CDK6 and/or CDK4, and/or CDKN2A
homozygous deletion, and/or amplification of CCND1 and/or CCND3 with no
deletion/losses more than single copy of RB1 by copy number and P53 wild-type.
- Cohort Cabozantinib : AXL, MET, VEGFR, VEGF, RET, ROS1, MER, TRKB, TIE-2 and/or
Tyro3 activating mutations and/or amplification, and/or NTRK translocation
and/or ROS1 translocation, and/or MET translocation.
- Cohort Alectinib : Activating ALK alterations: translocation, or selected
mutations, or activating rearrangements following validation by central
molecular tumor board of Centre Léon Bérard.
- Cohort Regoranib : Activating mutation and/or amplification and/or
rearrangement of VEGFR1-3, TIE-2, KIT, RET, RAF1, BRAF (other than V600
mutations), CRAF, HRAS, PDGFR, FGFR1-2, FLT3 and/or CSFR1, and/or amplification
of the ligands, and/or biallelic inactivation of SMAD4, following validation by
central molecular tumor board of Centre Léon Bérard.
- Cohort Trametinib : Activating mutation and/or amplification of KRAS (except
all KRAS G12 mutations), NRAS, HRAS and/or MAP2K; and/or biallelic inactivation
of NF1; and/or activating mutation PTPN11; and/or amplification or
translocation of BRAF, and/or translocation RAF1
