• NDA Application Fees: $3,116,000
• Biologics License Application Fees: $3,116,000
• Enhancement Fees: $1,557,000

The key review goal stipulated under PDUFA IV is to ensure the FDA acts on a standard review within 10 months of submission for a New Drug Application (NDA), bringing potential therapeutic agents to the market in a more timely manner. For Priority Review applications, the target timeline is reduced to 6 months, significantly expediting access to drugs designed to treat serious conditions.

2.2 Generic Drug User Fee Amendments (GDUFA)

Enacted in 2012, GDUFA was intended to improve the availability of generic medications. This act includes facility fees that manufacturers must pay to support the physical inspection of production establishments, ensuring they comply with the same rigorous standards as their brand-name counterparts.

As of the latest reauthorization (GDUFA II), the program has led to significant improvements in the review process, originally aimed at achieving a 90% review completion rate for ANDAs within 10 months. The GDUFA application fee structure includes:

• ANDA Application Fee: $1,402,000
• Generic Drug Facility Fees: Varies based on facility type and experience.

This structured fee model allows sponsors to predict expenses associated with the submission and enables the FDA to budget effectively for its oversight responsibilities.

2.3 Biosimilar User Fee Act (BsUFA)

BsUFA, enacted in 2012 alongside GDUFA, ensures that sponsors of biosimilar products can efficiently navigate the FDA’s approval processes. This act emphasizes the unique complexities associated with biosimilars compared to standard pharmaceuticals, requiring specialized assessment protocols.

The fees associated with BsUFA ensure adequate resources for the evaluation of these biologics, which include:

• BLA Application Fee: $2,571,000
• Biosimilar Development Fees: applicable during the pre-application process.

The goals set forth in BsUFA mandate that the FDA should review applications within 10 months for standard cases and expedited reviews within 6 months, similar to PDUFA goals, thereby maintaining a commitment to prompt access to life-saving therapies.

2.4 Medical Device User Fee Amendments (MDUFA)

MDUFA outlines the framework for the submission and review processes unique to medical devices. Initially established in 2002, recent reauthorizations have expanded the types of devices covered, ranging from Class I to Class III, reflecting ongoing advancements in medical technology. MDUFA establishes the following fee structures:

• 510(k) Submission Fees: $13,755
• PMA Application Fees: $408,000

MDUFA also stipulates performance goals related to the review timelines for these applications, promoting a commitment to facilitating timely innovations in the medical device field, ensuring compliance with safety and efficacy standards.

3. Review Timelines Associated with User Fee Acts

The review timelines stipulated by each user fee act represent the FDA’s commitment to efficiency and accountability in the decision-making process for drug and device approvals. Understanding these timelines can play a crucial role in strategic planning for sponsors.

3.1 NDA Review Goals and Timelines

For new drug applications submitted under PDUFA, the standard timeline for review is 10 months post-application submission, while for Priority Review applications, a timeline of 6 months is targeted. These timelines are critical for maintaining competitive market advantage and timely patient access to new therapeutics. Under PDUFA VI, these reviews are closely monitored through a commitment to transparency and annual performance evaluations.

3.2 ANDA Review Goals and Timelines

Similarly, GDUFA aims to achieve a completion rate of 90% for ANDA submissions within 10 months. The GDUFA II goals have also introduced enhanced communications between the FDA and applicants, allowing for more timely responses to inquiries. This is fundamental for sponsors, who must plan based on these expectations, especially when considering the introduction of generic alternatives to existing branded medications.

3.3 Biosimilar Review Timelines

The review timeline under BsUFA aligns closely with NBIAs, with biosimilars expected to undergo the same rigor in review timelines—of 10 months for standard applications and 6 months for Priority Reviews. The FDA has established these performance goals to foster development in an area that offers huge potential cost savings and patient benefits.

3.4 Device Performance Goals and Timelines

MDUFA review timelines vary significantly based on the classification of the device submitted.
