Product Description

Perjeta 420 mg Injection is a prescription monoclonal antibody used for the treatment of HER2-positive breast cancer. It is manufactured by Roche and contains the active ingredient pertuzumab. This medicine is indicated for use in combination with trastuzumab and docetaxel for patients with metastatic breast cancer, as well as in neoadjuvant and adjuvant settings for early-stage HER2-positive breast cancer. Perjeta works by binding to the HER2 receptor and preventing its interaction (dimerization) with other HER receptors. This blocks downstream signaling pathways responsible for cancer cell growth and proliferation. When used alongside trastuzumab, it offers a dual blockade, resulting in improved outcomes. Macarius Health ensures genuine, cold-chain maintained Perjeta for safe and timely treatment access across India.
