open label randomized comparative crossover pharmacokinetic and immunogenicity study

Conditions: Febrile Neutropenia

Summary: the goal of these study is to evaluate and to compare the pharmacokinetics (pk) of the test product (t) getting administered through prefilled syringe with on-body injector with reference product as prefilled syringe following a single 6 mg dose administered through subcutaneous route in healthy adult human subjects. subjects safety and immunogenicity will also be evaluated during these study as follows safety - monitoring the adverse events , vitals signs, ecg, laboratory parameters, and injection site assessment. immunogenicity assessment- detection of ada (anti-peg antibody levels ) and nab (neutralizing antibodies) will be done pre-dose and post dose on day 15 of each period.
