Inclusion criteria: Patients must meet all of the following criteria: 1. Female ≥18 years of age. 2. Written (signed and dated) informed consent. 3. Histologically or cytologically confirmed advanced, recurrent or metastatic ovarian cancer, endometrial cancer, triple-negative breast cancer i. Ovarian cancer: must have epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube cancer with high-grade serous or endometrioid features or a predominantly serous/endometrioid component ii. Endometrial cancer: must have advanced, recurrent or metastatic, endometrial cancer (any subtype excluding endometrial sarcoma) iii. Triple Negative Breast cancer: must have advanced, recurrent or metastatic triple-negative breast cancer (based on the most recently analyzed biopsy from locally recurrent or metastatic site, local laboratory) meeting the following criteria: * HER2-negative in situ hybridization test or an immunohistochemistry (IHC) status of 0 or 1+ * ER and PgR expressions \<10% as determined locally by IHC assay as per most recent ASCO/CAP guidelines 4. Tumour tissue expressing FRα on at least 5% of tumour cells, as determined by immunohistochemistry using either (i) the BN3.2 antibody (Leica Biosystems) or (ii) the FOLR1 (FOLR1-2.1) antibody (Ventana) Note: All patients must be willing to provide an archival tumour tissue block, or undergo a procedure to obtain a new biopsy, using a low risk, medically routine procedure for immunohistochemistry (IHC) confirmation of FRα positivity using BN3.2 antibody (Leica Biosystems). Note: Pre-screening for FRα positivity, using BN3.2 antibody (Leica Biosystems), may be performed at any point in advance of the first administration of MOv18 IgE i. Leica Biosystems BN3.2 antibody 1+ 2+ 3+ staining ii. Ventana FOLR1 antibody criteria 2+ 3+ membrane staining Note: Patients with a medical history confirming tumour tissue expression of FRα, as confirmed by the Ventana FOLR1 antibody, will be considered as meeting inclusion Criteria #4 and will not require a confirmation via Leica Biosystems assay prior to receiving MOv18 IgE. However, in all instances, confirmation of FRα expression using the BN3.2 antibody (Leica Biosystems), will be required to be tested during the trial. Confirmation is not required prior to C1D1. Note: Discordant results between the two systems will not result in patient removal from the trial unless deemed appropriate by the treating Investigator. 5. Negative basophil activation test (BAT) prior to the first administration of MOv18 IgE. Note: this test will be performed at a reference laboratory. 6. Ovarian cancer: platinum-free interval since last dose of platinum, of less than 6 months (182 days). 7. Prior therapies: Ovarian cancer: progressed following ≤2 prior regimens of anti-cancer therapy for platinum resistant ovarian cancer, and, at the time, no other authorised therapy is considered appropriate by the treating investigator. i. Patients who received hyperthermic intraperitoneal chemotherapy (HIPEC) or other IP therapies are eligible. Endometrial cancer: progressed after any prior line of systemic therapy, and, at the time, no other authorised therapy is considered appropriate by the treating investigator. Breast cancer: progressed after any prior line of systemic therapy, and, at the time, no other authorised therapy is considered appropriate by the treating investigator. 8. Has measurable disease as defined by RECIST v1.1 on CT or MRI scan i. Note: Baseline scans must be performed ≤28 days before the first administration of MOv18 IgE, after discontinuation of the prior regimen. ii. Note: Lesions previously embolised, perfused, or irradiated without objective evidence of progression before the first administration of MOv18 IgE are not allowed to be considered for response assessment. 9. No evidence of bowel obstruction. 10. ECOG Performance Status Score 0-1 prior to the first administration of MOv18 IgE. 11.

Haemoglobin level \>9 g/dL obtained within 14 days before the first administration of MOv18 IgE. Packed red blood cell transfusion is acceptable, if the patient has a stable result of ≥9 g/dL for at least 1 week post-transfusion. Erythropoietin should not be used to achieve this level. iv. Adequate coagulation function at screening as determined by prothrombin time (PT) ≤1.5 × upper limit of normal (ULN) or international normalised ratio (INR) \<1.5 and activated partial thromboplastin time (aPTT) ≤1.5 × ULN.

Adequate hepatic function: i. Serum total bilirubin ≤1.5 × ULN or direct bilirubin ≤ ULN for a patient with total bilirubin levels \>1.5 × ULN. ii. AST (SGOT) and ALT (SGPT) ≤2.5 × ULN or ≤5 × ULN for a patient with liver metastases. iii. Albumin ≥3.0 g/dL. 16.

No active or history of autoimmune disease, (with exception of vitiligo, type I DM, residual hypothyroidism due to autoimmune condition only requiring hormone replacement) and/or no history of autoimmune disease that required treatment with steroids or immunosuppressive medication within 6 months of the first administration of MOv18 IgE. 19. Negative serum or urine pregnancy test. 20. Women of childbearing potential must have 2 negative pregnancy tests during Screening, the second within 24 hours prior to the first administration of MOv18 IgE. This criterion does not apply to patients who have had a previous hysterectomy or bilateral oophorectomy. 21. Female patients of child bearing potential must agree to practice true abstinence or to use two forms of contraception, one of which must be highly effective. These forms of contraception must be used from the time of signing consent, throughout the treatment period, and for 6 months, (182 days), following the last dose of any study medication.

Patient has been advised to take measures to avoid or minimise exposure of the skin to UV light, including sunbathing and solarium use for the duration of the trial and for 4 weeks following last administration of MOv18 IgE. Exclusion criteria: Patients must not meet any of the following criteria: 1. Non-epithelial tumour of the ovary, the fallopian tube, or the peritoneum (including germ cell tumours and sarcomas). 2. Presence of ascites/pleural effusion requiring drainage within 28 days of first dose MOv18 IgE or persistent ongoing malignant ascites or pleural effusion requiring an in-dwelling drain. 3. Taking beta-blockers (at PI discretion) and unable to interrupt beta-blockade (which may counteract the therapeutic effects of adrenaline), or full dose tricyclic anti-depressants/MAOIs (which can dangerously augment the effects of adrenaline). These agents should be discontinued at least 4 half-lives before administration of the first dose of MOv18 IgE. Treatment may be reintroduced 48 hours post dose administration. i. Note: Beta blockers may continue if, in the opinion of the Investigator, it would not pose additional risk to the patient ii. Note: Only applies to full dose tricyclic anti-depressants. Low dose tricyclic anti-depressants to support conditions such as peripheral neuropathy, chronic pain, or insomnia, may be permitted at PI discretion 4. History of laryngeal oedema, uncontrolled or high-risk asthma, or anaphylaxis. Patients with a history of hypersensitivity to carboplatin, taxanes, or contrast media may enter the trial at the Investigator's discretion. 5.

Presence of CNS metastases (including spinal metastases) or CNS primary tumour, e.g., glioblastoma. 23. Clinically significant illness or major surgery within 4 weeks before the administration of MOv18 IgE. 24. Currently breastfeeding. 25. Any condition which could interfere with, or the treatment for which might interfere with, the conduct of the trial, or which would, in the opinion of the Investigator, unacceptably increase the patient's risk by participating in the trial 26.
