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 brand-side disclosures

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.

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.

Last updated: August 18, 2025

Introduction

The kit for the preparation of technetium Tc-99m albumin aggregated represents a specialized radiopharmaceutical instrument pivotal in diagnostic nuclear medicine. Utilized primarily in lung perfusion scans, this biologic kit enables rapid, reliable imaging of pulmonary blood flow, essential in diagnosing conditions like pulmonary embolism. As healthcare systems increasingly prioritize precise, minimally invasive diagnostics, the market trajectory for such radiopharmaceutical kits exhibits distinctive growth drivers, challenges, and emerging trends. This analysis delineates the comprehensive market dynamics and scrutinizes the financial outlook for this specialized biologic agent.

Market Overview

Historical Context and Market Size

Technetium-99m (Tc-99m) remains the backbone of diagnostic nuclear imaging worldwide, accounting for approximately 80-85% of all nuclear medicine procedures globally [1]. Among these, Tc-99m macroaggregated albumin (MAA) kits are integral for lung perfusion imaging, with a global market valuation estimated at USD 850 million in 2022. The increasing adoption of nuclear medicine diagnostics, especially in developed healthcare markets such as North America, Europe, and parts of Asia-Pacific, contributes significantly to this valuation.

Product Functionality and Clinical Application

The Tc-99m albumin aggregated kit facilitates the formation of macroaggregates that embolize in pulmonary capillaries accurately reflecting perfusion. This functional imaging provides critical insights into vascular pathologies, influencing clinical decisions in pulmonary embolism, lung cancer staging, and cardiopulmonary assessments.

Market Dynamics

Drivers

1. Rising Prevalence of Pulmonary Conditions:
   An aging global population and lifestyle factors contribute to increasing incidences of chronic pulmonary diseases and pulmonary embolisms, fueling demand for precise imaging diagnostics. The World Health Organization reports that pulmonary embolism mortality rates are rising, strengthening the need for effective lung perfusion scans [2].

2. Advancements in Nuclear Imaging Technologies:
   Innovations in gamma cameras, SPECT/CT hybrids, and improved radiotracer production methodologies enhance image resolution and diagnostic accuracy. These technological upgrades make Tc-99m MAA kits more attractive to nuclear medicine departments.

3. Regulatory Approvals and Market Access:
   Most national health authorities have approved Tc-99m MAA kits, reinforcing market stability. Moreover, approvals for kits with optimized formulations improve regulatory and reimbursement landscapes.

4. Growing Healthcare Investment and Infrastructure Expansion:
   Developing economies are increasingly investing in nuclear medicine infrastructure. Expanding access to diagnostic imaging broadens market potential.

Challenges

1. Limited R&D for Novel Alternatives:
   The entrenched reliance on Tc-99m MAA kits creates high barriers for alternative or more innovative agents, slowing market innovation.

2. Price Sensitivity and Reimbursement Constraints:
   Budget limitations and reimbursement policies in emerging economies restrict widespread adoption of expensive radiopharmaceutical kits.

3. Supply Chain Vulnerabilities:
   Tc-99m production relies heavily on aging nuclear reactors and aging reactor capacity, leading to potential shortages and price volatility [3].

4. Shelf-Life and Handling Complexities:
   The short half-life of Tc-99m (~6 hours) demands robust logistics, increasing operational costs and limiting geographic reach.

Market Segmentation

The dominant segment is the diagnostic lung perfusion imaging, representing approximately 75% of the demand, followed by niche applications in cardiology and tumor perfusion assessment. Geographically, North America accounts for nearly 50% of the market share, with Europe and Asia-Pacific contributing significant growth.

Financial Trajectory

Revenue Projections

Based on current utilization rates and technological advancements, the global market for Tc-99m MAA kits is projected to grow at a compound annual growth rate (CAGR) of approximately 4-5% from 2023 to 2030 [1]. Key factors influencing this trajectory include:

• Expansion in Emerging Markets:
  As nuclear medicine infrastructure develops in Asia-Pacific, Latin America, and the Middle East, market revenues are expected to diversify and expand.

• Enhanced Diagnostic Protocols:
  Increasing adoption of comprehensive nuclear imaging protocols, combining perfusion and ventilation scans, will augment kit sales.

• Potential Impact of Alternative Technologies:
  While Positron Emission Tomography (PET) with novel tracers offers high-resolution imaging, its limited availability and higher costs currently inhibit widespread replacement of Tc-99m-based kits, providing continued revenue streams for existing products.

Cost Dynamics

Raw material costs, particularly for albumin and other biologic components, influence manufacturing expenses. The reliance on complex supply chains for Tc-99m production (primarily from Molybdenum-99 generators) introduces price variability. Manufacturing costs are also impacted by stringent regulatory compliance and quality assurance standards prevalent for radiopharmaceuticals.

Profitability Outlook

Legacy manufacturers with established supply chains and regulatory approval portfolios maintain stable profit margins (~20-25%). Market entrants leveraging innovative formulations or superior imaging quality can command premium pricing, potentially boosting margins. However, commoditization risks pressure on pricing strategies in mature markets.

Emerging Trends and Opportunities

Innovation in Formulation and Delivery

Development of kits with enhanced stability, longer shelf life, and ease of preparation aims to reduce logistical burdens. Integrated kits that simplify clinical workflows could improve adoption rates.

Miniaturization and Automation

Automation in kit preparation promises increased safety, reproducibility, and operational efficiency — important differentiators in competitive environments.

Regulatory and Reimbursement Evolution

Streamlining approval pathways via harmonized international standards and expanding reimbursement coverage are critical growth enablers.
