Summary

To compare the efficacy and safety of PERT-IJS (Proposed biosimilar Pertuzumab) plus trastuzumab and chemotherapy (carboplatin and docetaxel) versus EU-Perjeta plus trastuzumab and chemotherapy (carboplatin and docetaxel) in neoadjuvant treatment of patients with HR-ve and HER-2 positive early stage or locally advanced breast cancer.

Detailed description

This study is designed to compare the efficacy and safety of proposed biosimilar PERT-IJS plus trastuzumab, carboplatin and docetaxel versus EU-Perjeta plus trastuzumab, carboplatin and docetaxel in neoadjuvant treatment of HR-ve HER2-positive Early Breast Cancer (EBC) (invasive breast cancer without distant metastasis) or locally advanced breast cancer patients.

Conditions

• HR Negative HER2 Positive Early Breast Cancer or Locally Advanced Breast Cancer Patients

Interventions

Type	Name	Description
BIOLOGICAL	PERT-IJS plus trastuzumab, carboplatin and docetaxel	PERT-IJS is a monoclonal antibody, which has been developed by Biocon Biologics (earlier in collaboration with Viatris) as a proposed biosimilar to European Union (EU)-approved and United States (US) licensed Perjeta.
BIOLOGICAL	Perjeta plus trastuzumab, carboplatin and docetaxel	EU Perjeta (Pertuzumab) , an antineoplastic agent, is a recombinant humanized monoclonal antibody that specifically targets sub-domain 2 of the extracellular domain of Human Epidermal Growth Factor Receptor 2 (HER2), blocking heterodimerization of HER2 with other members of the receptor family, including epidermal growth factor, Human Epidermal Growth Factor Receptor 3 (HER3) and Human Epidermal Growth Factor Receptor 4 (HER4).
