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

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.

2. DrugPatentWatch analysis and company disclosures

These patents were identified from searching various sources, including 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.

3. Patents from broad patent text search

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.

1) High Certainty: US Patents for ZYNLONTA Derived from Brand-Side Litigation

No patents found based on brand-side litigation

2) High Certainty: US Patents for ZYNLONTA Derived from DrugPatentWatch Analysis and Company Disclosures

No patents found based on company disclosures

3) Low Certainty: US Patents for ZYNLONTA Derived from Patent Text Search

No patents found based on company disclosures

rket Dynamics and Financial Trajectory for the Biologic Drug: ZYNLONTA

Introduction
ZYNLONTA (loncastuximab tesirine-lpyl) represents a promising addition to the oncologic biologics landscape. Approved in April 2021 by the U.S. Food and Drug Administration (FDA), ZYNLONTA is a CD19-targeted antibody-drug conjugate (ADC) designed to treat relapsed or refractory large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL). As a novel therapy, ZYNLONTA’s market entry influences shifts in lymphoma treatment paradigms, impacting players across clinical, commercial, and regulatory spectrums. This analysis evaluates the current market dynamics and projects the financial trajectory for ZYNLONTA within the expanding biologics sector.

Market Context and Therapeutic Landscape

The global lymphoma market is valued at approximately USD 11 billion, with B-cell lymphomas constituting a significant segment. The therapeutic landscape for relapsed/refractory LBCL has been dominated by chemotherapy, immunotherapy (e.g., rituximab), CAR T-cell therapies (e.g., axi-cel, tisa-cel), and other monoclonal antibodies. Recently, the introduction of ADCs like ZYNLONTA offers targeted options with the potential for efficacy in heavily pretreated populations.

The approval of ZYNLONTA marked a strategic milestone, being among the few ADCs approved for DLBCL and offering an alternative for patients ineligible for CAR T-cell therapy or who relapse after such treatments. The drug's mechanism—delivering cytotoxic agents directly to CD19-positive cells—addresses resistance issues and enhances targeted therapy options.

Market Dynamics Influencing ZYNLONTA

1. Competitive Treatment Algorithms
   The evolution from traditional chemotherapy to immunotherapies and CAR T-cell treatments has reshaped clinical decision-making. ZYNLONTA’s positioning focuses on relapsed/refractory settings where limited options exist. As clinicians seek efficacious, less invasive therapies, ZYNLONTA’s tolerability and convenience become key differentiators, influencing adoption rates.

2. Regulatory and Reimbursement Landscape
   While FDA approval provides a foundation, reimbursement decisions significantly influence market penetration. The coverage landscape for ADCs like ZYNLONTA is evolving, with payers scrutinizing clinical benefits, cost-effectiveness, and comparative effectiveness against existing standards such as CAR T-cells and chemotherapy. The therapy’s high manufacturing costs and pricing strategies will shape reimbursement pathways.

3. Clinical Data and Real-World Evidence
   The pivotal LOTIS-2 trial demonstrated an overall response rate (ORR) of approximately 48.6% in relapsed/refractory DLBCL, with manageable safety profiles. Ongoing and future studies aim to expand indications, including earlier lines of therapy and combinations with other agents (e.g., immunomodulators). Real-world evidence (RWE) emerging from initial post-marketing use will influence clinical uptake and perceived value.

4. Manufacturing and Supply Chain
   As an ADC, ZYNLONTA’s complex manufacturing process can impact supply consistency and costs. Strategic manufacturing partnerships and scalable processes are critical to meet increasing demand and manage costs. Supply chain robustness will directly influence market availability and patient access.

5. Patient and Provider Demand
   The unmet needs in relapsed/refractory DLBCL create a receptive environment for innovative therapies like ZYNLONTA. Patients ineligible for or resistant to CAR T-cell therapy may favor ZYNLONTA due to ease of administration and manageable safety profiles. Provider familiarity, clinical guidelines, and advocacy efforts further shape adoption patterns.

Financial Trajectory Projections

Given the novel mechanism and expanding clinical applications, ZYNLONTA’s revenue forecast hinges on multiple factors: clinical efficacy, market penetration, competitive landscape, pricing strategies, and regulatory developments.

1. Current Revenue and Growth Outlook
   Initial sales post-approval have been modest, aligning with typical launch phases of biologics in niche indications. In 2022, preliminary estimates suggest ZYNLONTA generated USD 50-100 million globally, primarily within the U.S. and select markets, given limited initial distribution. As awareness grows and off-label usage and combination therapies develop, revenue streams are expected to increase substantially.

2. Market Penetration Strategies
   Lilly (the marketing partner) and BeiGene, responsible for commercialization, are investing in physician education, clinical trial expansion, and strategic alliances to boost adoption. The expansion of indications—potentially into second-line settings or earlier treatment lines—could drive revenues to USD 500 million or more within five years, considering the sizable relapsed/refractory DLBCL patient population (~30,000 annually in the U.S. alone).

3. Pricing and Reimbursement Impact
   Pricing set around USD 15,000-$20,000 per infusion, based on ADC comparatives, with additional costs per treatment course, influences gross revenues. Reimbursement policies, negotiated discounts, and patient access programs are critical for maximizing market share. Price reductions or value-based agreements could shape financial outcomes, balancing affordability with innovation incentives.

4. Pipeline and Future Indications
   Clinical trials exploring ZYNLONTA in combined regimens, earlier lines, and other CD19-positive malignancies can substantially expand its addressable market. Positive trial results may lead to regulatory approvals in broader indications, bolstering revenue growth. Conversely, if competitors introduce more effective or cost-efficient therapies, ZYNLONTA’s market share could plateau or decline.

5. Competitive and Regulatory Risks
   Emerging ADCs and novel immunotherapies, including bispecific T-cell engagers, threaten to erode ZYNLONTA’s market share. Regulatory challenges concerning safety, efficacy, or manufacturing could delay or limit approval for extended indications, affecting revenue trajectories.

Long-term Financial Outlook

By 2030, ZYNLONTA could become a key player within lymphoma biologics, with projected cumulative sales reaching USD 2-3 billion globally if market expansion and line-of-therapy adoption proceed as planned. The trajectory remains sensitive to clinical success, payer acceptance, and competitive innovations. The evolving landscape underscores the importance of pipeline development, strategic partnerships, and adaptive pricing models for sustainable growth.

Strategic Recommendations for Stakeholders

• Pharmaceutical Companies: Focus on expanding indications through pivotal trials, optimizing manufacturing, and engaging payers early for favorable reimbursement pathways.
• Clinicians: Incorporate ZYNLONTA into treatment algorithms for relapsed/refractory DLBCL, particularly for patients unsuitable for CAR T-cell therapy.
