Phesgo (pertuzumab trastuzumab hyaluronidase)

Information on this site is not intended as medical advice and should not be used as a substitute for consulting with a qualified doctor.

Phesgo® combines the same HER2+ breast cancer treatments as IV Perjeta® (pertuzumab) and Herceptin® (trastuzumab) into a single injection.1

The active substances in Phesgo, pertuzumab and trastuzumab, are monoclonal antibodies (a type of protein) that have been designed to attach to HER2. HER2 is a protein on cancer cells that makes the tumour cells grow more quickly and that is present in large quantities in about a quarter of breast cancers. By attaching to HER2, pertuzumab and trastuzumab stop HER2 from producing signals that cause the cancer cells to grow. They also activate cells of the immune system (the body’s natural defences), which then kill the cancer cells. Pertuzumab and trastuzumab attach to 2 different parts of HER2 and their actions have a complementary effect. These combined actions slow down cancer growth.2

Phesgo is given as an injection under the skin (Subcutaneous). The first dose is given over 8 minutes as an injection containing pertuzumab 1200 mg and trastuzumab 600 mg. This is followed by an injection containing pertuzumab 600 mg / trastuzumab 600 mg given over 5 minutes every 3 weeks. The duration of treatment depends on whether Phesgo is given before or after surgery, and on the type of breast cancer being treated.2

In Bangladesh Phesgo is approved for the following indications.3

Phesgo is indicated in combination with chemotherapy for the:

  • neoadjuvant treatment of patients with HER2-positive, locally advanced, inflammatory, or early stage breast cancer (either >2 cm in diameter or node positive) as part of a complete treatment regimen for early breast cancer (see 3.1.2 Clinical Studies)

  • adjuvant treatment of patients with HER2-positive early breast cancer at high risk of recurrence (see 3.1.2 Clinical Studies)

Phesgo is indicated in combination with docetaxel for patients with HER2-positive metastatic or locally recurrent unresectable breast cancer, who have not received previous anti-HER2 therapy or chemotherapy for their metastatic disease.
