Inclusion Criteria:

• Locally advanced, or metastatic recurrent gynecological cancer, for whom no standard alternative therapy is available, having received at least one line of therapy and expressing AMHRII on tumor cells.
• If possible at least one lesion should be identified for 2 biopsies: a baseline biopsy and an under-treatment biopsy for AMHRII expression and GM102 pharmacodynamics evaluation.
• Available tumor block or at least 10 slides from formalin-fixed paraffin-embedded (FFPE) archival tissue.
• At least one measurable lesion by RECIST (Response Evaluation Criteria in Solid Tumors) on screening CT-scan.
• Written Informed Consent forms.
• Willing and able to comply with the trial requirements.
• Covered by healthcare insurance in accordance with local requirements.

For phase 1b, only patients with either Sex cord stromal tumors or epithelial ovarian cancer or cervix cancer will be eligible

• Concurrent chronic corticosteroid treatment.
• Known severe anaphylactic or other hypersensitivity reactions secondary to a prior exposure to human antibodies or to any protein product.
• Washout period before treatment initiation: < 3 weeks or 5 times the half-life, whichever is shorter, for prior antitumor therapy (small molecules and/or antibody-drug conjugates, radiotherapy) or 6 weeks for monoclonal antibodies.
• Any active concomitant malignancy.
• Serious concomitant illness e.g. active infection requiring systemic antibiotic, antifungal or antiviral drug, or physical examination or laboratory abnormalities, that, in the opinion of the Investigator, would compromise protocol objectives.

• Poor organ function as defined by any one of the following: left ventricular ejection fraction ≤ 40%, serum creatinine > 1.5 x upper limit of normal (ULN), total bilirubin > 1.5 x ULN, AST and ALT> 2.5 x ULN in the absence of liver metastasis or > 5 x ULN in case of documented liver metastasis.
• Non-resolution of any prior treatment related toxicity to < Grade 2, except for alopecia according to National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4.03.
• Pregnancy or breastfeeding.
• Patient with reproductive potential who do not agree to use an accepted effective method of contraception - investigator's judgment - during the study period and for at least 4 months following completion of study treatment.
