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.

Cancer treatment using the nanofiber mesh with self-heating/anticancer drug release functions
A research team headed by Dr. Mitsuhiro Ebara, a MANA Scientist of the Biomaterials Unit of the International Center for Materials Nanoarchitectonics (WPI-MANA, NIMS) developed a new nanofiber mesh which is capable of simultaneously realizing thermotherapy (hyperthermia) and chemotherapy (treatment with anticancer drugs) of tumors.
Using this nanofiber mesh, the team succeeded in efficiently inducing natural death (apoptosis) of epithelial cancer cells.
FDA awards Activartis brain cancer drug Orphan Drug Designation
Austrian biotech company Activartis has received Orphan Drug Designation for its cancer immunotherapy AV0113 from the US Food and Drug Administration.
The experimental vaccine will be fast-tracked for evaluation after it was shown to improve survival rates in people with malignant glioma, an advanced form of brain cancer in a phase II clinical trial earlier this year.

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)

ARIAD Announces Marketing Authorization for Iclusig® (ponatinib) in the European Union
CAMBRIDGE, Mass. & LAUSANNE, Switzerland–(BUSINESS WIRE)–Jul. 2, 2013– ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced that the European Commission (EC) has granted a marketing authorization for Iclusig® (ponatinib) as an orphan medicinal product for two indications:read all at

Ponatinib (Iclusig, previously AP24534) is an FDA approved oral drug candidate developed by ARIAD Pharmaceuticals for the treatment of chronic myeloid leukemia (CML) and Philadelphia chromosome positive (Ph+) acute lymphoblastic leukemia (ALL). It is a multi-targeted tyrosine-kinase inhibitor. Some forms of CML, those that have the T315I mutation, are resistant to current therapies such as imatinib. Ponatinib has been designed to be effective against these types of tumors.
Oncologists have complained, however, that many patients can’t afford the “astronomical” cost of $138,000 a year, which makes it one of the most expensive drugs in medicine, and far more expensive than what is needed to pay the development costs.
Ponatinib was approved by the US FDA on December 14, 2012, for patients with resistant or intolerant CML and Ph+ ALL, based on results of the PACE phase II trial reported days earlier at the annual ASH meeting.Because the approval was under the FDA’s accelerated approval program the applicant will be required to carry out additional studies.
The PACE (Ponatinb Ph+ ALL and CML Evaluation) pivotal phase II trial started enrolling patients in September 2010 and is designed to provide definitive clinical data for regulatory approval in this setting. Good results were reported in Dec 2012.
At the 2010 annual meeting of the American Society of Hematology, ARIAD announced from a Phase I study of ponatinib in patients with resistant and refractory chronic myeloid leukemia (CML) and Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL). The study demonstrated that in chronic-phase CML patients treated with ponatinib, 66 percent of patients in the trial achieved a major cytogenetic response, including 100 percent of patients who also had a T315I mutation
