Earlier this week, the Food & Drug Administration (FDA) released a Part 15 public hearing announcement and request for comment on how the FDA can facilitate greater availability while balancing competition and innovation for all biologics.

Tune in to the final podcast in our series as we discuss 3 steps companies should complete now to take advantage of the FDA’s priority to advance the adoption of RWE to support agency decision-making.

Avalere evaluated payer policies for biologics when biosimilars are available.

In just two years, on March 23, 2020, biologics currently regulated as drugs will transition to being regulated as biologics. Many aspects of how FDA will implement this transition have yet to be established.

Tune in to episode 2 of our discussion covering why the FDA is so interested in real-world evidence and how they are approaching it.

Most people are familiar with generic drugs as less costly alternatives to drugs whose patents have expired.

In the US, an interchangeability designation by the Food & Drug Administration (FDA) is perceived as the holy grail in biosimilars development by some and yet regarded as irrelevant by others.

Tune in to our new real-world evidence podcast series, where Avalere experts explore real-world evidence as a disruptive force in healthcare. In Episode 1, we focus on why RWE is such a hot topic.

In its new regulatory framework for regenerative medicines released in November 2017, FDA takes a flexible approach, creating opportunity for manufacturers.

The FDA Reauthorization Act of 2017 (FDARA), which was signed into law on August 18, 2017, calls on FDA to examine underlying barriers to access to investigational drugs.

Today, the Senate voted to pass H.R.2430, the FDA Reauthorization Act of 2017.

New research from Avalere finds that most health plans are covering at least one of the two biosimilar products currently on the market.

Biosimilars have the opportunity to foster competition, but policy and market barriers limit the growth of a functioning market.

The 21st Century Cures Act requirement to post compassionate use policies may explain increase.

Extension of the Sunset Clause provides additional opportunity for the FDA to award vouchers and for transference of vouchers from recipients to other sponsors.

The final signing of the 21st Century Cures Act is the culmination of 3 years of efforts by lawmakers in the House and Senate to expedite developing and making available new treatment options. In the final episode in our series, Jay Jackson discusses what changes are on the horizon for products under The Cures Act.

The final signing of the 21st Century Cures Act is the culmination of three years of efforts by lawmakers in the House and Senate to expedite developing and making available new treatment options. Listen to Cara Kelly break down the impacts in episode 1 of our series on 21st Cures.

Today, the House will vote on the updated version of the 21st Century Cures Act, H.R. 34.

Proposed Requirements in 21st Century Cures Act Would Increase Transparency Requirements

Since 1992, the Food and Drug Administration (FDA) has collected $7.67 billion in user fees from pharmaceutical manufacturers to fund drug reviews based on an Avalere analysis of FDA data.

The US Food and Drug Administration (FDA) makes its medical product marketing approval decisions based on a risk–benefit determination of safety and effectiveness.

With the recent announcement of the U.S. Food and Drug Administration's (FDA) acceptance of a submission for approval of a second biosimilar to Remicade (infliximab), questions remain for biologics manufacturers, payers, prescribers, and others as to how a mature biosimilars pipeline will begin to evolve in the United States and whether a sustainable competitive specialty market will develop.

Two Potential Policy Changes Would Reduce Out-of-Pocket Costs for Consumers

Almost every state has introduced Right-to-Try bills to try to offer patients another avenue to access investigational drugs outside of the Food and Drug Administration's (FDA) expanded access program. However, it is unclear whether these laws will impact patient access given their questionable legal standing, reduced patient protections due to lack of FDA oversight, and the risks to manufacturers of providing products under Right-to-Try laws.

In recent years, stakeholders have increasingly become aware of the potential opportunities surrounding incorporation of the patient perspective into early stages of drug development. Listen to Debleena Sengupta discuss how patient input is evaluated and incorporated into the FDA's decision-making process.

User fees are increasingly central to the funding of the drug and device review programs, and in some cases these fees account for a larger proportion of the Food and Drug Administration's (FDA) budget than congressionally-appropriated monies. For example, user fees account for 68 percent of the FDA's review budget for prescription drugs, while 58 percent of the review budget for generic drugs comes from user fees.

In Biosimilars, Avalere's Gillian Woollett shares commentary on future considerations for the role of clinical trials in the development of biosimilars.

FDA oversees access to investigational treatments by eligible patients (compassionate use) through its expanded access program. But how do you decide whether to give these patients the unapproved treatments they seek?

The U.S. Food and Drug Administration's (FDA) Advisory Committee (AdComm) process remains a source of significant uncertainty for medical product manufacturers, despite FDA's guidelines in the Code of Federal Regulations (C.F.R.)1 and in guidance.2 While the AdComm process is generally the same across Centers,3 each AdComm is unique and subject to the expertise and opinions of individual panel members, opinions voiced during the public comment period, and challenges exclusive to each new product or indication.

When life sciences companies consider whether to allow compassionate use—access to unapproved investigational treatments outside of clinical trials—there are no easy answers. Brenda Huneycutt gleans insight from Arthur Caplan, PhD, and Alison Bateman-House, PhD, from the New York University Langone Medical Center Division of Medical Ethics on some of the many questions that life sciences companies should ask themselves before implementing a compassionate use policy.

The FDA has shown growing interest in regulating laboratory developed tests (LDTs) to ensure their safety and effectiveness.

Need to Know: On June 10, Friends of Cancer Research held a public meeting to discuss how sponsors and FDA may be able to expedite rate-limiting steps in Chemistry, Manufacturing, and Controls (CMC) and current Good Manufacturing Practices (cGMPs) for breakthrough therapy designated products, while ensuring an adequate supply of safe and efficacious product at the time of approval.

Providing patient access to investigational treatments outside of clinical trials is once again in the spotlight of media scrutiny. Earlier this year, social and popular media attention pressured one company to provide an investigational treatment to a young cancer patient. Then, states began debating and passing “Right to Try” bills to set up a new pathway to allow access to investigational drugs.

Even during these gridlocked times in Congress, certain healthcare initiatives are getting through the cracks; one of these such initiatives is 21st Century Cures.
