Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

  1. Brand-side disclosures in response to biosimilar applications
  2. These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

  3. General brand-side disclosures
  4. These patents were identified from searching drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

  5. Patents from broad patent text search
  6. For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

Market Dynamics and Financial Trajectory for the Biologic Drug: PADCEV

Introduction

PADCEV (enfortumab vedotin-ejfv) is a groundbreaking biologic drug that has recently made significant strides in the treatment of advanced bladder cancer. Developed by Astellas Pharma Inc. and Seagen Inc., PADCEV has garnered considerable attention due to its innovative mechanism of action and promising clinical outcomes. Here, we delve into the market dynamics and financial trajectory of this pivotal drug.

Approval and Regulatory Milestones

PADCEV, in combination with KEYTRUDA (pembrolizumab), was approved by the U.S. Food and Drug Administration (FDA) on December 15, 2023, as the first and only antibody-drug conjugate (ADC) plus PD-1 inhibitor for the treatment of advanced bladder cancer[1][4].

Breakthrough Therapy Designation

In February 2020, PADCEV in combination with KEYTRUDA received Breakthrough Therapy designation from the FDA, highlighting its potential to offer substantial improvement over existing treatments. This designation expedited the development and review process[4].

Priority Review and Accelerated Approval

The FDA granted Priority Review for the supplemental Biologics License Application (sBLA) for PADCEV with KEYTRUDA in November 2023. Additionally, in April 2023, the FDA granted accelerated approval for this combination for patients not eligible for cisplatin-containing chemotherapy, based on the EV-103 trial[4].

Clinical Efficacy and Impact

EV-302 Trial Outcomes

The EV-302 trial, which served as the confirmatory trial for the U.S. accelerated approval, demonstrated that PADCEV plus pembrolizumab nearly doubled the median overall survival compared to standard platinum-based chemotherapy. This significant improvement underscores the potential of this combination to revolutionize the treatment of advanced bladder cancer[1].

Patient Outcomes and Quality of Life

The improved survival rates and good response to treatment observed in clinical trials are outcomes highly valued by patients. These results indicate that PADCEV, when used in combination with KEYTRUDA, can significantly enhance the quality of life for patients with locally advanced or metastatic urothelial carcinoma[3].

Market Reception and Adoption

Commercial Performance

The robust launch of PADCEV has driven exceptional commercial performance. In the second quarter of 2023, PADCEV saw a 36% net product sales growth over the first quarter, contributing to record product sales for Seagen[5].

Market Share and Growth Projections

Astellas Pharma Inc. expects PADCEV to achieve near double growth and further significant growth in FY2024. This optimism is based on the drug's strong market reception and the expanding indication into the cisplatin-eligible patient population[2].

Financial Implications

Revenue and Sales

The financial performance of PADCEV has been impressive, with significant revenue growth. The combination of PADCEV with other growth drivers like XTANDI, XOSPATA, VEOZAH, and IZERVAY has contributed to a substantial increase in sales for Astellas Pharma Inc.[2].

Cost and Budget Impact

While PADCEV offers significant clinical benefits, its high cost is a concern. Based on public list prices, PADCEV is expected to cost public drug plans an additional $99,379,089 over three years. This has raised concerns about the feasibility of adoption and the need for a significant price reduction to ensure cost-effectiveness[3].

Adverse Reactions and Safety Profile

Common Adverse Reactions

The most common adverse reactions leading to dose reduction of PADCEV include peripheral neuropathy, rash, and fatigue. These side effects are crucial considerations in the management and treatment planning for patients[4].

Hyperglycemia and Diabetes

PADCEV has been associated with hyperglycemia and diabetic ketoacidosis (DKA), particularly in patients with pre-existing diabetes mellitus. Patients with higher body mass index and higher baseline A1C levels are at increased risk of developing Grade 3-4 hyperglycemia[1].

Economic and Cost-Effectiveness Analysis

Cost-Effectiveness Threshold

Economic evidence suggests that PADCEV is not considered cost-effective at a willingness-to-pay (WTP) threshold of $50,000 per quality-adjusted life-year (QALY). A 93% price reduction would be necessary to ensure cost-effectiveness at this threshold[3].

Budget Impact

The estimated budget impact of PADCEV over three years is substantial, with significant variability between the sponsor’s estimate and the estimate by CADTH. This uncertainty highlights the need for careful budget planning and negotiation to ensure affordable access to this treatment[3].

Industry Expert Insights

Bladder Cancer Advocacy Network

Andrea Maddox-Smith, CEO of the Bladder Cancer Advocacy Network (BCAN), has expressed excitement about the FDA approval, noting that it provides hope for extended survival and improved treatment options for bladder cancer patients[1].

Future Outlook

Expanding Indications

The approval of PADCEV with KEYTRUDA for first-line treatment of advanced bladder cancer is expected to expand its market reach. Ongoing trials and regulatory submissions aim to further broaden the indication into the cisplatin-eligible patient population[4].

Competitive Landscape

In the competitive landscape of oncology treatments, PADCEV stands out due to its unique mechanism of action and strong clinical data. As more patients and healthcare providers become aware of its benefits, it is likely to gain a significant market share.

Key Takeaways

  • FDA Approval: PADCEV with KEYTRUDA was approved by the FDA for the treatment of advanced bladder cancer, marking a significant advancement in oncology.
  • Clinical Efficacy: The EV-302 trial demonstrated nearly doubled median overall survival compared to standard chemotherapy.
  • Market Reception: PADCEV has shown strong commercial performance with significant revenue growth.
  • Financial Implications: High costs pose a challenge, with a need for substantial price reductions to ensure cost-effectiveness.
  • Safety Profile: Common adverse reactions include peripheral neuropathy, rash, and fatigue, with a risk of hyperglycemia and DKA.
