Generics and the News – Bad Start to the Week or Just Business as Usual?

From the news stories on the price fixing suits, to the reported revelations about quality in the generic drug industry, or to the publication of a book titled “Bottle of Lies”, it has not been a good start to the news cycle for the generic drug industry this week.  The report on price fixing was met with a response to 60 Minutes May 12,

A Deeper Dive on the Biosimilar Interchangeability Guidance Viewed from Our Biologics Expert

On Friday May 10, the FDA published the much-anticipated final version of the guidance document Considerations in Demonstrating Interchangeability with a Reference Product.  We did a general post here  and, while recognizing the final version is similar (highly similar?) to the previous draft from January 2017, a careful review (as outlined here) found several useful and potentially significant changes in the final guidance.

Biosimilar Interchangeability Guidance Hits the Street

The issue of the use of biosimilars and their uptake in the market has been a discussion point since the first biosimilar was approved in 2015.  Today, the FDA issued a long-awaited guidance on how a firm can demonstrate interchangeability of a biosimilar to its reference licensed product.

Real World Data and Evidence Coming to an Application Near You?

The FDA released a draft guidance today titled Submitting Documents Using Real-World Data and Real‑World Evidence to FDA for Drugs and Biologics (here) that describes how the Agency will receive Real World Data (RWD) and Real World Evidence (RWE) and the potential use of each.  After reading the draft guidance, it seems to me that the industry is still far away from being able to rely on RWD and RWE for use in supporting initial application approval,

Accelerated Approval and DTC Advertising – FDA Proposes a Study to Inform Which Direction to Take

In the Federal Register (FR) pre-publication page (here) today, FDA announced a proposed study to evaluate patient/consumer ability to understand the impact of Direct to Consumer (DTC) advertising for products with accelerated approvals.  These products are typically approved based on a surrogate endpoint (such as a blood test) that has a reasonable likelihood to predict clinical benefit.
