Who Owns Perjeta?
Perjeta (pertuzumab) is owned by Roche (SIX: ROG; OTCQX: RHHBY), a publicly traded Swiss multinational pharmaceutical and diagnostics company headquartered in Basel, Switzerland. Perjeta was developed by Genentech, a Roche subsidiary. The FDA approved Perjeta on June 8, 2012, for HER2-positive metastatic breast cancer in combination with Herceptin (trastuzumab) and docetaxel, based on the CLEOPATRA Phase 3 trial. Perjeta targets domain II of the HER2 receptor, a different binding site than Herceptin (which targets domain IV), enabling dual HER2 blockade when the two drugs are used together. In December 2017, Perjeta received FDA approval for adjuvant treatment of HER2-positive early breast cancer based on the APHINITY trial.

History of Perjeta
- Founded: 2012
- Founders: Genentech (developer; Roche subsidiary)
Perjeta's development originated from Genentech's research into the biology of HER2 receptor signaling and the mechanisms by which HER2-positive cancers can evade single-agent HER2-targeted therapy. Scientists at Genentech recognized that HER2 drives cancer cell growth partly through forming dimers (pairs) with other HER family receptors, particularly HER3. The HER2-HER3 dimer is a particularly potent driver of cancer cell proliferation.
Genentech developed pertuzumab as a humanized monoclonal antibody that binds to domain II of the HER2 receptor, which is the dimerization domain through which HER2 forms pairs with other HER family receptors. By binding to domain II, pertuzumab blocks HER2 from forming dimers with HER3 and other HER family members, disrupting a key signaling pathway that drives HER2-positive cancer cell growth.
Critically, pertuzumab binds to a different domain of HER2 than trastuzumab (Herceptin), which binds to domain IV. This complementary binding allows pertuzumab and trastuzumab to be used together to achieve more complete HER2 blockade than either drug alone, a strategy known as dual HER2 blockade.
Genentech conducted the pivotal Phase 3 CLEOPATRA trial, which compared the combination of pertuzumab, trastuzumab, and docetaxel to the combination of placebo, trastuzumab, and docetaxel in patients with HER2-positive metastatic breast cancer who had not received prior anti-HER2 therapy or chemotherapy for metastatic disease. CLEOPATRA demonstrated that adding pertuzumab to trastuzumab and docetaxel significantly improved progression-free survival and overall survival, with the pertuzumab arm achieving a median overall survival of 56.5 months compared to 40.8 months in the control arm.
The FDA approved Perjeta on June 8, 2012, for use in combination with Herceptin and docetaxel for the treatment of patients with HER2-positive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. This was the first FDA approval for dual HER2 blockade and established the pertuzumab plus trastuzumab plus chemotherapy regimen as the standard first-line treatment for HER2-positive metastatic breast cancer.
Perjeta subsequently received FDA approval for neoadjuvant treatment of HER2-positive locally advanced, inflammatory, or early-stage breast cancer in September 2013, and for adjuvant treatment of HER2-positive early breast cancer at high risk of recurrence in December 2017. The adjuvant approval was based on the APHINITY trial, which demonstrated that adding pertuzumab to trastuzumab and chemotherapy as adjuvant therapy significantly reduced the risk of invasive disease recurrence in HER2-positive early breast cancer.
Perjeta has become one of Roche's important oncology products, generating significant revenues as a standard component of HER2-positive breast cancer treatment. The drug is typically used in combination with Herceptin, and the two drugs are often administered together in the same infusion visit, making the combination convenient for patients.
Roche has also developed Phesgo, a fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection, which was approved by the FDA in June 2020. Phesgo allows patients to receive both pertuzumab and trastuzumab in a single subcutaneous injection administered in approximately 5-8 minutes, compared to the approximately 60-150 minutes required for separate intravenous infusions of Perjeta and Herceptin.
