Denosumab of Intas is biosimilar denosumab candidate under development by Intas Pharmaceutical Limited (Biopharma Division). Denosumab of Intas is already approved by Indian drug licensing authority- Drug Controller General (India) for marketing in Indian population since 2018.As per regulatory requirement, a comparative clinical study to establish Pharmacokinetic, Pharmacodynamic and Immunogenicity equivalence is required to conclude therapeutic equivalence to obtain marketing authorization of a biosimilar investigational product. This is a multicenter, randomized, double-blind, active controlled study in approximately 552postmenopausal women with osteoporosis.

An extension of the study is planned after completion of the initial 1 year of treatment. This extension is with the objective of submitting data on safety, and Immunogenicity, after switching of Prolia treatment arm to either Prolia or Intas denosumab for 6 months. This switching data is applicable only for FDA submission. Only patients who have undergone PK assessment will be eligible for the extension phase.
