This study evaluates the bioequivalence, pharmacokinetic (PK) profile, and safety and tolerability of Iron Sucrose (Test Product) relative to that of Venofer® in healthy subjects.

Inclusion Criteria:

• Healthy males or non-pregnant, non-lactating healthy females

• Age 18 to 55 years of age (both inclusive)

• Must, in the opinion of the investigator, be in good health based upon medical history, physical examination (including vital signs and ECGs) and clinical laboratory tests assessed at the time of screening

• Body mass index (BMI) of 18.0 to 32.0 kg/m2 and a minimum body weight of 40 kg, or if outside the range, considered not clinically significant by the investigator

• Ferritin levels not less than the lower limit of normal as defined by clinical laboratory reference ranges for female and male subjects at screening only

• Transferrin Saturation (TSAT) not less than the lower limit of normal as defined by clinical laboratory reference ranges for female and male subjects at screening only

• Must be willing and able to comply with all study requirements

• Must be able to understand a written informed consent, which must be obtained prior to initiation of study procedures

Exclusion Criteria:

• Hypersensitivity to iron sucrose or iron products
• Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hay fever is allowed unless it is active
• Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients
• Clinically significant abnormal biochemistry, hematology or urinalysis as judged by the investigator
• History of iron deficiency within 6 months prior to screening
• History of anemia within 6 months prior to screening
• Suspicion of iron overload as evidenced by both elevated serum TSAT and serum ferritin levels
• History of hemochromatosis
• Bleeding disorders, acute bleeding or recently documented hemorrhage
• Females with history of hypermenorrhea or menorrhagia
• History of cardiovascular, pulmonary, hepatic, renal, gastrointestinal, endocrine, immunological, dermatological, neurological or psychiatric disease or disorder, as judged by the investigator

• Positive drugs of abuse test result or history of drug abuse in the past 6 months based on subject report
• Positive urinalysis test for alcohol at screening or history of alcoholism in the past 6 months based on subject report
• Regular alcohol consumption in males >21 units per week and females >14 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 Units = 125 mL glass of wine, depending on type)
• Administration of an injectable drug within 14 days prior to drug administration in this study
• Subjects who are taking, or have taken, any prescribed or over-the-counter drug (other than up to 4 g per day acetaminophen in the 14 days before IMP administration, hormonal contraceptives, or hormone replacement therapy. Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the PI and sponsor's medical monitor
• Use of iron supplements (including iron-containing multivitamins) within 3 months of the first dose IMP administration in the study
• Have poor venous access that limits phlebotomy
• Subjects who have donated blood (1 unit = 450 mL) within 3 months prior to the first dose of the study drug and plasma within 7 days prior to the first dose of the study drug.
• Subjects who have received any IMP in a clinical research study within 5 half-lives or within 30 days prior to first dose. However, in no event, shall the time between last receipt of IMP and first dose be less than 30 days
• Subjects who are study site employees, or immediate family members of a study site or sponsor employee
• Subjects who have previously been enrolled in this study
• Failure to satisfy the investigator of fitness to participate for any other reason
