Who's Who in the Biosimilar Space?

In 2004, the European Commission adopted a new directive that paved the way for legal approval of biosimilars in the European Union (EU). To date, five (5) biosimilars have garnered marketing approval in the EU. Of the five, two are generic versions of recombinant growth hormone (rHGH)–Omnitrope (Sandoz) and Valtropin (Biopartners). The remaining three are “knock off” versions of erythropoietin alpha–Binocrit (Sandoz), Epoetin alpha Hexal (Hexal) and Abseamed (Medice Arneimittel Putter).

There is no doubt, at this point, that Europe is leading the way in the biosimilar space. However, it is important to point out that a variety of biosimilars, developed by Indian generic manufacturers and others, are already being sold in less- regulated Asian markets (see Table 1). Unfortunately, political issues and the fierce struggle between innovator

biotechnology companies and generic manufacturers have delayed development of legislation for regulatory approval of follow-on biologics (American lingo for biosimilars) in the US. Further, and perhaps more perplexing, the FDA has been reluctant to issue any guidance on the topic. However, rising drug costs and increasing expenditures on biologics (both by Medicare and private insurers) have left American lawmakers with no choice but to craft legislation for approval of follow-on biologics.

In the first half of 2007 alone, three different bills were proposed to craft a statutory pathway for the approval of follow-on biologics under the Biologic License Application (BLA). The first of these bills–The Access to Life-Saving Medicine Act– was introduced into Congress by Representative Henry Waxman (CA) and into Senate by Senator Chuck Schumer (NY) in February. The second bill–the Patent Protection and Innovative Biologic Medicine Act –was introduced in Congress in April by Representative Jay Inslee (WA). Neither bill made any progress. This is because the Access to Life-Saving Medicine Act was considered to be heavily pro-follow-on whereas the Patent Protection and Innovative Biologic Medicine Act was deemed to favor innovator companies and did not provide any financial incentives for follow-on manufacturers.


A compromise was reached by both Republican and Democrat Senators and the Biologics Price Protection and Innovation Act was approved by the Senate on June 27.  It proposes 12 years of market exclusivity for the patent holders but also one year of exclusivity to the first follow-on biologic to be approved as interchangeable with the reference product.  I previously aired my views on the proposed legislation. For a more in depth analysis of the issues and the bills, please read this.

Recently, there was an important new regulatory development in the European biosimilar landscape. Sandoz’s EPO, Binocrit, received the same nonproprietary name (INN) as Amgen’s original erythropoietin alpha (Epogen in the US, Eprex in Europe).This was a big win for the biosimilar industry because the INN debate had been raging in the EU for the past several years. Innovator companies wanted biosimilars to have different INN than their products whereas biosimilar manufacturers were lobbying for identical INN designation. An identical INN designation allows for  interchangeability of medicines. The fact that EMEA granted Binocrit the same INN number as Eprex, means that the agency views the two products as biologically-equivalent and interchangeable. This paves the way for EU pharmacists to freely substitute Binocrit for the more expensive Eprex. Also, it sends a message to US lawmakers and FDA that the EU considers certain biosimilars as interchangeable with their innovator counterparts. As you may have guessed, the issue of interchangeability is being hotly debated and contested by advocates on both sides of the follow-on biologics fence.

The US is clearly dragging its feet in the follow-on biologics arena. The prime driver of this inertia is the imagined loss of revenue that many innovator companies fear will occur if the US ultimately divines a regulatory approval pathway for follow-on biologics. That said, with Europe and India leading the charge into Asia, it looks as though the US is going to loss a substantial amount of money (not to mention market share) anyway.

With regard to biosimilars in the US, it is no longer a question of “if” but “when.” That said, I think that the one seminal issue that needs to be addressed is what to call these things in the US?  In my opinion, the European moniker, biosimilar, is particularly apt and appropriate for this new class of medicines. Unfortunately, we Americans don’t like to play second fiddle to anybody, especially the Europeans. With this in mind, I have no doubt that they WILL NOT be called biosimilars in the US. Whatever they are called, don’t be surprised to find them your pharmacist’s shelves in the next couple f years!

Until next time….

Eli Lilly & Co. to Eliminate 500 Jobs

Eli Lilly & Co. announced today that it will eliminate 500 jobs at its manufacturing facility in Indianapolis, IN. The cuts will affect sites that manufacture active pharmaceutical ingredients for Lilly’s insulin products Humalog® and Humulin® and its osteoporosis medicine Forteo®.

Lilly is offering incentive packages for those employees who voluntarily leave the company. The company has already reduced its global headcount by twelve percent or about 5,500 people since 2004.

Times are tough and getting tougher each day in pharma land. Buckle up–its going to be a rough ride for jobseekers in the pharmaceutical and biotechnology industries.

Until next time….

Good Luck and Good Job Hunting (avoid Indianapolis, who wants to be a Hoosier anyway?)

More Downsizing on Both Sides of the Atlantic

Cambridge, MA-based Alkermes announced today that it is restructuring its operations following the termination by Eli Lilly and Company of its inhalable AIR Insulin program (Alkermes manufactured the inhaler delivery device). The company is reducing its workforce by approximately 150 employees and closing its AIR commercial manufacturing facility in Chelsea, MA. The company is taking these actions based on its current expectations of the financial impact of Lilly's termination of the AIR Insulin program.

The job cuts, effective this week, represent almost 18% of Alkermes’ total workforce. Employees affected by the restructuring will be eligible for a severance package that includes severance pay, continuation of benefits and outplacement services. The company expects cost savings from the restructuring in the range of $15 million to $20 million in fiscal 2009.

In other news from across the pond, the trade group, the Association of the British Pharmaceutical Industry (ABPI), reported today that the UK pharmaceutical industry lost about 8.000 pharmaceutical jobs or about 10% of its workforce over the past three years. The ABPI asserts that there is a direct link between job cuts and changes to the British government’s pricing mechanisms for medicines. A spokesperson for the group said “Every time a new PPRS (Pharmaceutical Price Regulation Scheme) comes into force there is a decline in the number of jobs”. Not surprisingly, the group is urging the government to not make any changes in the PPRS.

The UK pharmaceutical workforce has taken a number of big hits of late– Pfizer recently closed a manufacturing plant in Kent, while British drug makers AstraZeneca and GlaxoSmithKline both announced substantial global job cuts many of which were located in Britain.

Until next time….

Good Luck and Good Job Hunting!!!!

Inhalable Insulin: Not Worth the Effort?

The Danish drug maker Novo Nordisk announced today that it was halting further clinical development of its inhalable insulin product called AERx. AERx was in Phase 3 clinical testing as a short-term diabetes treatment. In a press release the company stated that it was halting development of its inhaled insulin compound because the drug was "unlikely to offer significant clinical or convenience benefits" versus current diabetes treatments.” AERx joins Exubera (Nektar Therapeutics/ Pfizer) on the inhalable insulin scrap heap. This leavesEli Lilly and Alkermes’ IR insulin system as the only inhalable short-acting diabetes treatment in Phase 3 clinical development.

Interestingly, Novo didn't say that it was giving up on developing inhalable insulins— only that it was halting its current late-stage AERx program. The company did announce that it plans to pursue a Glucagon_Like Protein (GLP-1) inhalable diabetes treatment which is similar to a product being developed by California-based MannKind. Its product in Phase 1 clinical testing. Unlike Nektar, which partnered with Pfizer to develop Exubera, MannKind, a small startup, is developing its inhalable insulin product alone. Novo also disclosed plans to develop a longer-acting injectable form of insulin which would eliminate the need for daily injections by patients with diabetes.

In theory, inhalable insulins make sense—many people hate daily injections. That said, inhalable insulins may create other problems that obviate their usefulness as alternatives to daily insulin injections-just ask Pfizer and Nektar about that!

Until next time….
