Carcinosarcomas (CS) (malignant mixed Mllerian tumors) are highly aggressive and rare tumors with a worldwide annual incidence between 0.5-3.3 cases/100.000 women. Gynecological CS, i.e. ovarian CS (OCS) and uterine CS (UCS), have a 5-year overall survival (OS) < 10% and a poor prognosis. After initial treatment (surgery +/- adjuvant radiotherapies +/- chemotherapies (CT)), vast majority of patients relapsed and received diverse CT producing modest benefits, and nearly all patients will die. After first line CT including platinum salt, monotherapy (doxorubicin or paclitaxel) is frequently used for relapsed patients, but the response rate (RR) is <20%, progression-free survival (PFS) <4 months, and OS <1 year. In this unmet need situation, a better knowledge of these aggressive neoplasms is essential to propose new therapeutic options.

Patients who have been amenorrhoeic for <2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure
For women of childbearing potential: the patient must be willing to use 2 adequate barrier methods throughout the study, starting with the screening visit through 180 days after the last dose of study treatment. See Section 4.3. for a list of acceptable birth control methods. Information must be captured appropriately within the site's source documents. Note: Abstinence is acceptable if this is the established and preferred contraception for the patient
Patient must agree to not breastfeed during the study and for 180 days after the last dose of study treatment
Patient able to take oral medications
21\. Female aged 18 years at time of signing ICF
Patient must have signed an approved informed consent
For France only: patient affiliated to, or a beneficiary of, a social security category

Exclusion Criteria

Not enrolled in any interventional clinical trial (except to biological trials that must be validated by the sponsor)
Prior treatment with niraparib or other PARPi therapy or PD1/PDL-1 inhibitors
Patient has had investigational therapy, immunotherapy, chemotherapy or biological therapy administered within 4 weeks or within a time interval less than at least 5 half-lives of the investigational agent, whichever is longer, prior to randomization. Patient has had radiotherapy within 4 weeks prior to randomization
Patient must not have had major surgery 3 weeks prior to initiating protocol therapy and participant must have recovered from any surgical effect
Previous treatment with the chemotherapy regimen selected as the control arm by the investigator
Prior therapy with paclitaxel given on a three-weekly regimen is permitted for patients receiving weekly Paclitaxel

Patients with any other severe concurrent disease, which may increase the risk associated with study participation or study drug administration and, in the judgment of the investigator, would make the patient inappropriate for entry into this study, including significant neurologic, psychiatric, infectious, hepatic, renal, or gastrointestinal diseases or laboratory abnormality.
