Two biosimilars bills have just been introduced in the House, each of which would establish regulatory path for biosimilars to be approved.

The first bill, HR 1427, the Promoting Innovation and Access to Life Saving Medicine Act, was introduced on March 11, 2009 by Representatives Henry Waxman (D-CA), Frank Pallone (D-NJ), Nathan Deal (R-GA), and Jo Ann Emerson (R-MO).

A second bill was introduced the following week. H.R. 1548, the Pathway to BioSimilars Act, was introduced on March 17, 2009 by Representatives Anna Eshoo (D-CA), Jay Inslee (D-WA), and Joe Barton (R-TX).

What are the key elements of each of the bills?

According to the HR 1427 Bill Summary, highlights of HR 1427 include as follows:

• FDA authority to approve biosimilars;
• approval process will require showing that (1) there are no clinically meaningful differences between the two products and (2) that the two products are highly similar in molecular structure and share the same mechanisms of action;
• biosimilar may establish that it is “interchangeable” with the original product, and the first such biosimilar able to make such a showing will receive six months of exclusive marketing;
• an original product with a novel molecular structure is entitled to five years of exclusive marketing, and a modification of a previously approved product is entitled to three years of exclusive marketing.  These periods can be extended by up to one year if it can be established that the product can be used for a new disease or that it conducts pediatric studies; and
• a new procedure is established to resolve patent disputes prior to approval of the biosimilar, and penalties are put in place for failure to timely litigate such disputes.

In contrast, highlights of HR 1548 are as follows:

• establishes safey standards for establishing interchangeability;
• establishes exclusivity for the first  product found to be “interchangeable”  for a period of 24 months after the product has either been deemed to be interechangeable or goes on sale;
• the reference product receives 12 years exclusivity, and that period of exclusivity will extend to 14 years in the event that a new indication is found for the product in the first 8 years after licensure;
• an additional exclusivity period is also established for pediatric studies and use of product;

Which bill has been more widely received by the biotech industry?

Well, the biotech industry group BIO has indicated its preference for the second bill, according to reports by Fierce Biotech.    Fierce Biotech explained as follows:

For biotech companies, the difference between five years and 12 years of exclusivity could amount to billions of dollars.

In contrast, BIO did not have such a positive opinion of the first bill, stating in a press release as follows:

Unfortunately, the legislation introduced today would take patients and our industry down the wrong path – a path that jeopardizes the continued development of new breakthrough therapies and potential cures for debilitating diseases such as multiple sclerosis, HIV/AIDS and Alzheimer’s. . . .

“This bill seeks to cut prices but instead cuts corners.  This proposal leads us off the map as we seek an effective, fair and safe pathway to a biosimilars market.

“The legislation introduced today does not strike the necessary balance for patients or the economy.   Any biosimilars legislation must ensure safe and effective biosimilars, promote the continued development of new therapies and cures, and ensure the benefits of additional competition among biologics through the entry of biosimilars.

The California Biotech Law Blog will continue to follow this issue as debate on each of the proposed bills continues.
