Biosimilar drugs step up complexity, by Phillip Broadwith
The first ever generic monoclonal antibody therapies have been recommended for approval in Europe. The two biosimilar versions of infliximab (Johnson & Johnson’s Remicade) have passed assessment by the European Medicines Agency’s committee for medicinal products for human use, but will need to be fully approved by the European commission before they can be marketed.
Monoclonal antibodies are significantly larger and more complex than previously approved biosimilars, which include growth hormones and erythropoietin. Proving that they are functionally similar to the original drug is therefore complex. Both manufacturers, Celltrion and Hospira, had to complete human trials to prove that their generic infliximab products were as safe and effective as Remicade in treating autoimmune diseases.

Roche’s Perjeta Gets FDA Priority Review
The structure of HER2 and pertuzumab
Application follows proposed new FDA pathway designed to help bring promising medicines to people with earlier stages of breast cancer faster
Perjeta is one of the first medicines the FDA will evaluate as an option given before surgery (neoadjuvant treatment)
Perjeta, in combination with Herceptin and chemotherapy, was approved by the FDA in 2012 for HER2-positive metastatic breast cancer
Pertuzumab (also called 2C4, trade name Perjeta) is a monoclonal antibody. The first of its class in a line of agents called “HER dimerization inhibitors”. By binding to HER2, it inhibits the dimerization of HER2 with other HER receptors, which is hypothesized to result in slowed tumor growth. Pertuzumab received US FDA approval for the treatment of HER2-positive metastatic breast cancer on June 8, 2012. Pertuzumab was developed at Genentech and is now owned by Roche which acquired Genentech in 2009.
Early clinical trials of pertuzumab in prostate, breast, and ovarian cancers met with limited success.
The dosage of pertuzumab used in the pivotal phase III CLEOPATRA (Clinical Evaluation of Pertuzumab and Trastuzumab) trial was as follows: IV 840 mg loading dose followed by IV 420 mg every three weeks.
The pharmacokinetics of intravenous pertuzumab appear to be unaffected by age and no drug-drug interaction has been reported with docetaxel. The pharmacokinetics and pharmacodynamics of pertuzumab were summarized in a Feb 2012 review by Gillian Keating.
The combination of pertuzumab plus trastuzumab plus docetaxel, as compared with placebo plus trastuzumab plus docetaxel, when used as first-line treatment for HER2-positive metastatic breast cancer, significantly prolonged progression-free survival, with no increase in cardiac toxic effects in the randomized, double-blind, multinational, phase III CLEOPATRA trial.
Intravenous pertuzumab is currently being evaluated in patients with breast cancer in the following trials: MARIANNE (advanced breast cancer), NEOSPHERE (early breast cancer), TRYPHAENA (HER2-positive stage II/III breast cancer) and APHINITY (HER2-positive nonmetastatic breast cancer)
BMS, Pfizer: Eliquis Meets Phase III Goal
Eliquis® (apixaban) Demonstrated Comparable Efficacy and Significantly Lower Rates of Major Bleeding in Patients Compared to Current Standard of Care for the Treatment of Acute Venous Thromboembolism
Phase 3 AMPLIFY Results Published in New England Journal of Medicine and Presented as a Late-Breaker at the Congress of the International Society on Thrombosis and Haemostasis Show:
•Eliquis Was Noninferior to Current Standard of Care for Treatment of Both Symptomatic Deep Vein Thrombosis and Pulmonary Embolism Conditions
•69 Percent Relative Risk Reduction for Major Bleeding in Patients on Eliquis Compared to Current Standard of Care “The study results showed that apixaban, as a single-agent, has comparable efficacy with significantly fewer major bleeding events with respect to the standard of care.
These results complement the previously published results for the AMPLIFY-EXT study” PRINCETON, N.J. and NEW YORK, June 30, 2013
