    FAQs

    What is the role of pertuzumab in the treatment of HER2 positive breast cancer? ›

    Pertuzumab inhibits tumor growth by sterically blocking the formation of HER2 ligand-receptor complexes. The formation of heterodimers is inhibited (eg, HER2–HER3, HER2–HER4 heterodimers, etc). The antibody blocks ligand-activated HER2 signaling, whereas trastuzumab does not.

    What is the mechanism of action of trastuzumab and pertuzumab? ›

    Pertuzumab acts to inhibit the classical HER2-mediated cell-signaling cascades by blocking HER2 dimerization. Trastuzumab acts through ADCC and the inhibition of HER2 cleavage.

    Why are pertuzumab and trastuzumab given together? ›

    Previous studies proved that the combination of trastuzumab and pertuzumab demonstrated a strongly enhanced antitumor effect combined as compared with either agent alone in preclinical studies (5).

    What is the difference between trastuzumab and trastuzumab pertuzumab? ›

    differences between trastuzumab and pertuzumab

    Pertuzumab efficiently inhibits ligand-induced HER2/HER3 dimerization, whereas trastuzumab has only a minor effect in the presence of a ligand. Other differences between pertuzumab and trastuzumab are summarized in Table 2.

    Is trastuzumab used for HER2-positive breast cancer? ›

    Herceptin (chemical name: trastuzumab) is a HER2 inhibitor targeted therapy. Herceptin works against HER2-positive breast cancers by blocking the ability of the cancer cells to receive chemical signals that tell the cells to grow.

    Is HER2-positive breast cancer treatment? ›

    HER2-directed therapy — Most women with HER2-positive breast cancer will receive one or more chemotherapy drugs plus trastuzumab, the anti-HER2 antibody. Many studies have shown that these treatments dramatically improve survival for women with HER2-positive breast cancer.

    How effective is trastuzumab and pertuzumab? ›

    In conclusion, in patients with HER2-positive metastatic breast cancer, the addition of pertuzumab to trastuzumab and docetaxel, as compared with the addition of placebo, significantly increased the median overall survival to 56.5 months, an improvement of 15.7 months over survival in the control group, and extended ...

    What is the clinical benefit of pertuzumab? ›

    Pertuzumab Provides Long-Term Benefit in HER2+, Operable Breast Cancer. Adding pertuzumab to adjuvant chemotherapy and trastuzumab can improve long-term outcomes in patients with operable, HER2-positive early breast cancer, according to updated results from the phase 3 APHINITY trial.

    Is Herceptin and PERJETA considered chemotherapy? ›

    Perjeta (pertuzumab) is considered a targeted cancer therapy, which is different from chemotherapy. Chemotherapy works by killing rapidly growing cancer cells, but may also affect normal cells. Perjeta attacks certain proteins on breast cancer cells that cause rapid growth.

    Which toxicity is associated with trastuzumab and pertuzumab? ›

    Cardiac toxicity, although asymptomatic in most cases, was associated with this treatment. Further evaluation of efficacy of this combination is required to define the overall risks and benefits.

    What are the side effects of trastuzumab and pertuzumab? ›

    Metastatic Breast Cancer (based on IV pertuzumab)

    The most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel were diarrhea, alopecia, neutropenia, nausea, fatigue, rash, and peripheral neuropathy.

    What are the advantages and disadvantages of trastuzumab? ›

    In particular, the authors found that “trastuzumab improved overall survival and progression-free survival in HER2-positive women with metastatic breast cancer, but it also increased the risk of cardiac toxicities, such as congestive heart failure and LVEF decline.

    Does pertuzumab and trastuzumab cause hair loss? ›

    Hair thinning or hair loss

    Pertuzumab and trastuzumab do not usually cause people to lose their hair. Any hair loss caused by chemotherapy should be temporary and in most cases your hair will begin to grow back once your chemotherapy has ended.

    What type of therapy is pertuzumab? ›

    Perjeta (chemical name: pertuzumab) is a HER2 inhibitor targeted therapy. Perjeta works against HER2-positive breast cancers by blocking the cancer cells' ability to receive growth signals.

    Is pertuzumab necessary? ›

    use prior to surgery (neoadjuvant treatment) in people with HER2-positive, locally advanced, inflammatory, or early stage breast cancer (tumor is greater than 2 cm in diameter or node-positive). PERJETA should be used as part of a complete treatment regimen for early breast cancer.

    What is the function of pertuzumab? ›

    Pertuzumab works by locking onto HER2 on the cancer cells. It stops them from growing and kills them. Pertuzumab only works if your cancer is HER2 positive.

    What is the benefit of pertuzumab? ›

    What are the advantages of pertuzumab? Recurrence: The study suggests that pertuzumab has an advantage here. After an interim observation period of 45 months, 9 out of 100 women who had treatment with pertuzumab, trastuzumab and chemotherapy had a recurrence. Without pertuzumab, this happened in 12 out of 100 women.

    What is the best chemotherapy for HER2-positive breast cancer? ›

    Tucatinib (Tukysa®) received FDA approval in 2020 in combination with Herceptin® and chemotherapy (capecitabine) for treating HER2-positive metastatic breast cancer that can't be removed with surgery (unresectable), or that has spread to other parts of the body.
