Inclusion Criteria

Is your age greater than or equal to 18 yrs?
Gender: Male or Female
Do you have Solid Tumor?
Do you have any of these conditions: Solid Tumor or Solid Tumors or Solid Tumour or Solid Neoplasm?
Signed informed consent form
Age 18 years
Patients must have histologically or cytologically confirmed progressive metastatic or recurrent solid tumor (as defined below for each tumor type). Diagnosis must be stated in a pathology report and confirmed by the investigator
Representative archival formalin-fixed paraffin-embedded (FFPE) tumor specimens in paraffin blocks (preferred) or 20 freshly cut and unstained slides, with an associated pathology report, for ancillary studies and central testing, is mandatory for all cohorts. In all cases, recovery of the most recent tumor block or biopsy is encouraged and tumor tissue has to date back from less than 3 years ago. If tumor tissue is more than 3 years old, a fresh tumor biopsy is mandatory for cohorts 1, 2 and 4
Specificities for Cohorts 1A-D
For patients with DNA repair gene mutation already identified by local testing, mutational testing must have been done less than one year prior to inclusion in the trial (i.e. signing of informed consent). Tumor block should correspond to the one that has been used for the original testing. If more recent blocks are available, these should be provided for ancillary studies, and the presence of the mutation of interest should be confirmed on these
If no archival tissue is available or if tumor tissue is more than 3 years old, feasibility of a fresh tumor biopsy at baseline (C0D1 pre-dose) should be ensured and mutation confirmed on that tissue for cohorts 1A, 1B and 1D. Only tissue from core needle, punch or excisional biopsy sample collection will be accepted. Other methods such as fine-needle aspiration, brushing, bone tissue or lavage samples are not acceptable
Bone biopsies are allowed for mCRPC (cohort 1C), if sufficient tumor cellularity can be achieved
Specificity for cohort 3
If no archival tumor biopsy is available, a new fresh biopsy should be done prior to treatment start (C0D1 pre-dose) whenever feasible; otherwise, any archival tumor tissue will be accepted
Core or excisional biopsy from soft tissue or a bone biopsy is required from a site not previously irradiated (samples from tumors progressing in a prior site of radiation are allowed; other exceptions may be considered after Sponsor consultation)
Measurable disease, defined as
For the non-prostate cohorts: At least one lesion, not previously irradiated, measurable according to RECIST v1.1 as 10 mm in the longest diameter (except lymph nodes which must have short axis 15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) and suitable for repeated assessment
For prostate cohorts: At least one lesion, not previously irradiated, measurable according to RECIST v1.1 and / or bone scan measurable disease (Cf inclusion criteria 4) and / or measurable disease according to Prostate Cancer Working Group Criteria 3 (PCWG3) 7. Agreement of the patient to sign the genetic analysis consent form for access to plasma samples for ctDNA analysis
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 with no deterioration from registration date
Estimated life expectancy of greater than 12 weeks. 10. Adequate hematologic and organ function, defined by the following laboratory results obtained within 3 days prior to the first study treatment (Cycle 0 Day 1)
Absolute neutrophil count (ANC) 1500 cells/L (without granulocyte colony-stimulating factor support within 2 weeks before cycle 0 day 1)
Platelet count 100.000/L (without transfusion within 2 weeks before Cycle 0 Day 1)
Hemoglobin 9g/dL (patients may be transfused or receive erythropoietic treatment to meet this criterion)
Total bilirubin 1.5 ULN (subjects with documented/suspected Gilbert's disease or liver metastases may be enrolled with bilirubin 3 ULN)
Aspartate aminotransferase (AST) or Alanine aminotransferase (ALT) 2.5 x upper normal limit (ULN) or 5 ULN in case of liver metastases
Albumin 28g/L
Serum creatinine 1.5 x ULN or creatinine clearance 40mL/min (according to Cockroft and Gault formula)
International normalized ratio (INR) and activated partial thromboplastin time (aPTT) 1.5 x ULN. This applies only to patients who do not receive therapeutic anticoagulation; patients receiving therapeutic anticoagulation (such as low-molecular weight heparin or warfarin) should be on stable dose
Women of childbearing potential must have a negative serum -HCG pregnancy test within 7 days prior to the administration of the first study treatment 12. Sexually active women of childbearing potential must agree to use a highly effective method of contraception << supplemented by a barrier method >>, or to abstain from sexual activity during the study and for at least 6 months after the last study treatment administration
Sexually active males patients must agree to use condom during the study and for at least 6 months after the last study treatment administration. Also, it is recommended their women of childbearing potential partner use a highly effective method of contraception
A woman is considered of childbearing potential following menarche and until
becoming post-menopausal ( 12 months of non-therapy-induced amenorrhea) unless
permanently sterile. Permanent sterilization methods include hysterectomy
bilateral oophorectomy and bilateral salpingectomy. A highly effective birth
control method is a one which can achieve a failure rate of less than 1% per
year when used consistently and correctly. Such methods include: combined
(estrogen and progesterone containing) hormonal contraception; progestogen-
only hormonal contraception associated with inhibition of ovulation
intrauterine device (IUD); intrauterine hormone-releasing system (IUS)
bilateral tubal occlusion; vasectomized partner (on the understanding that
this is the only one partner during the whole study duration), and sexual
abstinence during the entire period of risk associated with study treatment
To prevent the risk of interaction between the study drug and hormonal
contraceptives, hormonal contraceptives should be supplemented with a barrier
method (preferably male condom). Following methods are considered as
unacceptable methods (non-exhaustive list): periodic abstinence (calendar
symptothermal, post-ovulation methods) and withdrawal (coitus interruptus)
\. Patient should understand, sign, and date the written informed consent
form prior to any protocol-specific procedures performed
\. Patient should be able and willing to comply with study visits and
procedures as per protocol
\. Patients must be affiliated to a social security system or beneficiary of
an equivalent system
