A Proof of Concept Study to Evaluate Exosomes From Human Mesenchymal Stem Cells in Women With Premature Ovarian Insufficiency (POI) (VL-POI-01)

Inclusion Criteria: Able to understand and communicate in English language Female of age 18-43 years Diagnosis of premature ovarian insufficiency based on ESHRE Guidelines (i) oligo/amenorrhea for at least 4 months, and (ii) an elevated FSH level >25 IU/L on two occasions >4 weeks apart, or diagnosis of low ovarian reserve defined as: Basal FSH value >10 IU/L or failure of prior attempts of assisted reproductive techniques due to limited ovarian response (poor responders) Normal karyotype 46, XX, and no known history FMR1 premutation (fragile X syndrome) Baseline AMH levels ≤ 1.0 ng/mL Presence of at least one ovary Normal uterine anatomy (by any clinically and/or imaging acceptable methods) Normal thyroid function as evident by normal serum Thyroid Stimulating Hormone (TSH) levels For subjects who had contraception before, the duration of amenorrhea should be more than 3 months after discontinuation of the oral contraception pill (OCP) or more than 6 months after discontinuation of Depo Provera (or similar) therapies Agree to report any pregnancy to the research staff immediately Willing and able to comply with study requirements and follow up instructions Patient with known history of endometriosis or polycystic ovarian syndrome If subject is planning to pursue pregnancy: presence of at least unilateral tubal patency (with any clinically acceptable methods) Exclusion Criteria: Currently pregnant or breast-feeding Has a history of, or evidence of current gynecologic malignancy, breast cancer or other estrogen responsive cancer or any other malignancy within the past five years Subjects with FMR1 premutation (fragile X syndrome), a BMP15 mutation or family history of a first degree relative with POI Presence of adnexal masses indicating the need for further evaluation Major mental health disorder that precludes participation in the study Active substance abuse or dependence Current or recent (within the past 2 weeks) use of the following medications: Oral or systemic corticosteroids, Hormones (estrogen, progestin, oral contraceptives), Danazol, anticoagulants, herbal or botanical supplements with possible hormonal effects. Washout will be allowed (2 weeks from screening) Subjects under hormonal treatments including hormone replacement therapy (HRT) for osteoporosis, cardiovascular disease, or recalcitrant vasomotor symptomatology within 3 months from screening Subjects with a history of breast cancer or other estrogen responsive cancer within 5 years from screening Subjects with existing malignant neoplasm, under active management for malignant neoplasm or under active surveillance for malignant neoplasm within 5 years from screening Subjects with history of thromboembolic events such as pulmonary embolism, stroke, or ischemic heart disease Subjects with uncontrolled hypertension, kidney disease, liver disease, or polycystic ovary syndrome (PCOS) as defined below: Uncontrolled hypertension: Systolic BP ≥ 140 and/or Diastolic BP ≥90 in patients taking anti-hypertensive treatment Kidney Disease: an estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m^2 (Incase the result is above/below acceptable range, one repeat test is acceptable) Liver Disease: Serum aminotransferase (ALT or AST) levels > 2x ULN PCOS criteria: Oligo-anovulation (Irregular periods), antral follicle count (AFC) >12 measuring 2-9mm, hyperandrogenism (elevated testosterone and DHEA levels), clinical hirsutism Subjects with untreated endocrinopathies including Cushing's disease, thyroid disease, congenital adrenal hyperplasia and hyperprolactinemia Subjects with intra-uterine devices (IUDs) Subjects who are allergic to low-molecular-weight heparin sodium or human albumin Medical conditions that are contraindicated in pregnancy Type I or Type II diabetes mellitus, or if receiving antidiabetic medications within 3 months from screening Known anemia (Hemoglobin < 11 g/dL) History of deep venous thrombosis, and/or pulmonary embolus History of cerebrovascular disease History of contrast media allergy Known heart disease (New York Heart Association Class II or higher) Known Liver disease (defined as Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) >2 times normal, or total bilirubin >2.5mg/dL) Known Renal disease (defined as Blood urea nitrogen (BUN) >30 mg/dL or serum creatinine > 1.6 mg/dL)
