About this study

Gestational trophoblastic neoplasias (GTN) are characterized by the persistence of elevated hCG titers after complete uterine evacuation of a partial hydatidiform mole (PHM) or a complete hydatidiform mole. Low-risk GTN patients (FIGO score ≤ 6) are commonly treated with single agent treatment (methotrexate or actinomycin-D) The cure rate, assessed by hCG normalization, is obtained in 65 to 75% of patients with these agents GTN patients with resistance to these treatments are treated with another single agent drug or polychemotherapy regimens, such as EMA-CO or BEP regimen. Chemotherapy standard regimens are old and toxic for these young lady patients, with potential long term effects detrimental for further maternity and quality of life There is a strong rational for investigating the anti-PDL1 monoclonal antibody avelumab in chemoresistant GTN patients. Several elements suggest that the normal pregnancy immune tolerance is "hijacked" by GTN cell for proliferating : * Spontaneous regressions of metastastic GTN are regularly observed, thereby the role of immune system for rejecting GTN cells. * Strong and constant overexpression of PDL1 and NK cells has been found in all subtypes and settings of GTN tumors from French reference gestational trophoblastic center. * Complete and durable responses to pembrolizumab were reported in 3 patients with multi-chemoresistant GTN in United Kingdom. * Three cases of hCG normalization with avelumab in 6 patients with chemo-resistant GTN…
