ExclusionCriteria 
Details  1. Positive test result for syphilis, hepatitis B, hepatitis C, or HIV-1 or -2.
2. Any prior exposure to darbepoetin or to any other erythropoiesis stimulating agent including investigational products [example: Epogen® (epoetin alfa) and its biosimilar/s].

4. Hemoglobin concentration higher than “ULN - 0.5 gm/dl”; reticulocyte percent >3% serum ferritin <100 mcg/L or transferrin saturation NOT within the normal laboratory reference range for the study site or transferrin or serum vitamin B12 or folate below the lower limit of the reference range at Screening.
Note: “ULN – 0.5 gm/dl”: Upper Limit of Normal reference range of the study site for haemoglobin subtracted with 0.5 gm/dl
5. Known history or presence of hemoglobinopathies including but not limited to sickle cell disease or trait and thalassemias. If suspecting any, to be ruled out by appropriate tests.

Note: Up to two repeats in different days are allowed (repeats on the same visit can be done if white coat hypertension is suspected) and, in this case, the mean of the measurements will be used to decide on eligibility. Blood pressure is to be measured in the sitting position after 5 minutes rest on the same position.
9. History of relevant (in the Opinion of the Investigator) orthostatic hypotension, fainting spells, or blackouts as well as history of difficulties with blood sampling which potentially may interfere with the study objectives, as per the opinion of the Investigator.
10. QTc (Fridericia correction) longer than 450 milliseconds or other ECG abnormalities such as atrial fibrillation, atrial flutter, Wolf-Parkinson-White syndrome, or presence of a cardiac pacemaker or any other ECG abnormality considered clinically relevant by the Investigator.
11. History or presence of any clinically relevant nervous system disease including, but not restricted to any stroke/TIA or of seizures other than febrile seizures before the age of 5 years.
12. History of and/or current gastrointestinal, neurological, renal, endocrine,
pulmonary, hepatic, cardiovascular (including history of or presence of angina, exertional dyspnea, orthopnea, congestive heart failure or myocardial infarction and thrombotic or embolic episode requiring treatment), hematological [including pancytopenia, aplastic anemia, or blood dyscrasia and coagulopathies or an International Normalized Ratio (INR) higher than 1.5] or metabolic (including known diabetes mellitus) disease. This criterion also includes any disorder or condition that, in the Investigator’s opinion, may interfere with the safety of the subject, the study evaluations or the subject compliance to the study procedures and limitations.
13. Participants who have abnormal liver function tests as evaluated by the investigator will be excluded from the study. A single repeat in a different day is allowed. Subjects who have documented evidence of presence of Gilbert’s disease may be included in the study if they have total bilirubin of <3 mg/dL with indirect bilirubin contributing to >80% of the total bilirubin as per the laboratory test.
14. Participation in an interventional or Phase 1 study in the last three months, currently is on follow-up visit schedule for any study, participation in more than 3 studies of experimental drug products in the past 12 months, or intake of an investigational drug in another trial within 3 months or 5 half-lives (whichever is longer) prior to intake of IMP in this trial or planned intake of an investigational drug during the course of this trial. Some examples of drugs, that are exceptions to this criterion and their adequate washout period (either as an investigational product or for treatment) are provided for reference:
14.1 Medications which require longer washout:
14.1.1 10 weeks: Bismuth salts, digitoxin, fluoxetine, flurazepam, medazepam, mephenytoin, mephobarbital, phenprocoumone, phenylbutazone, pimozide, pirimethamine, phenobarbital, primidone, protryptiline, teicoplanin
14.1.2 18 weeks: flunarizine, mefloquine, trimethadione
14.1.3 26 weeks: gold salts, immunoglobulins (antitetanus and antirabies post-exposure prophylaxis allowed until 3 weeks predose) or antibodies (monoclonal or not) systemic retinoids, chloroquine, hydroxychloroquine, and amiodarone

16. Major surgery within the past 6 months, or any surgery planned within 3 months of study enrolment.
17. Current smokers or those who gave up smoking less than 3 months prior to screening, (thus 3 months cessation required at screening time), tobacco chewer or positive in the urine cotinine test at Screening and check-in/admission to clinical facility.
18. Positive test for alcohol in breath test or drugs of abuse (benzodiazepine, amphetamines, barbiturates, cocaine, methadone, phencyclidine, 3, 4 methylenedioxymethamphetamine (ecstasy), tetrahydrocannabinol, and opiates) in urine at Screening or on the day before dosing.

Individual Participant Data (IPD) Sharing Statement

Will individual participant data (IPD) be shared publicly (including data dictionaries)?  

Response - NO
Brief Summary   It is a Phase 1 comparative study conducted by Dr. Reddy’s Laboratories Ltd in male volunteers with DRL_DA vs. Aranesp to compare the Pharmacokinetic parameters.

Dr.Reddy’s darbepoetin alfa (company product code: DRL_DA) is being developed as a biosimilar to the Reference Medicinal Product (RMP-EU approved Aranesp®) as a part of global development program. Normal healthy volunteers (NHV) are the population of choice (unless precluded for safety reasons) to establish PK similarity. The current study will be performed only in male subjects to avert gender-related variability. The 60 mcg IV single dose is known to be safe for administration to NHV as it has been tested with appropriate safety and tolerability in prior studies.
