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.

This growth is driven by robust performance in key segments such as retail pharmacy and Integrated Delivery Networks (IDNs) and Large Clinics, where the vaccine holds market shares of 55% and 56%, respectively[1][5].

For the full year 2024, Dynavax expects HEPLISAV-B net product revenue to be between $265 million and $270 million, with a gross margin of approximately 80%[1][3].

Segment Performance

Retail Pharmacy

HEPLISAV-B's market share in the retail pharmacy segment has seen significant growth, increasing to 55% in the third quarter of 2024 from 53% in the same period the previous year. This segment has been a strong contributor to the vaccine's overall market performance[1][5].

In the IDNs and Large Clinics segment, HEPLISAV-B's market share has also risen, reaching 56% in the third quarter of 2024, up from 54% in the third quarter of 2023. This segment's growth underscores the vaccine's acceptance and preference among healthcare providers[1][5].

Financial Highlights

Future Outlook

Market Expansion

Dynavax anticipates that the hepatitis B adult vaccine market in the U.S. will expand to over $900 million in annual sales by 2030, with HEPLISAV-B expected to achieve at least 60% of the total market share. This long-term guidance suggests double-digit annual growth for HEPLISAV-B's net product sales out to 2030[1][5].

Durability of Market Opportunity

The market opportunity for HEPLISAV-B is expected to remain substantial beyond 2030, driven by ongoing vaccination of the eligible adult population, observed revaccination practices by healthcare providers, and continued gains in market share[1][5].

Clinical Pipeline and Development

While HEPLISAV-B is the flagship product, Dynavax is advancing a pipeline of differentiated product candidates leveraging its CpG 1018 adjuvant technology. However, the company has discontinued its Tdap-1018 vaccine program due to insufficient differentiation[1].

Plague Vaccine Program

Dynavax is also working on a plague vaccine candidate, with top-line data from a Phase 2 clinical trial expected in 2024. This program is part of the company's broader strategy to expand its product portfolio[4].

Regulatory Developments

The cost of sales for HEPLISAV-B has been managed effectively, with decreases noted in various quarters. For instance, in the second quarter of 2024, the cost of sales for HEPLISAV-B decreased, contributing to improved margins[2][3].

Research and Development Expenses

Research and Development (R&D) expenses have seen fluctuations, with increases in some quarters due to ongoing clinical trials and pipeline development. However, these expenses are managed within a guided range of $60-75 million for the full year 2024[2][3].

Selling, General, and Administrative Expenses

Selling, General, and Administrative (SG&A) expenses have increased to support the growth of HEPLISAV-B, particularly in marketing and sales efforts. These expenses are expected to be between $160-180 million for the full year 2024[2][3].
