Lymphangioleiomyomatosis (LAM) Market Trends

Growth Drivers

• Increased Government Spending on Healthcare: government's focus and funding on rare disease treatments reflect a global push to address underserved medical needs. Companies are engaging with policymakers in Asia Pacific, and the overall healthcare budgets are poised to surge by 7.1% every year to secure subsidies and expand global reach. In 2023, U.S. Medicare dedicated USD 0.54 billion for market-related products, consisting of mTOR inhibitors and numerous diagnostic tools. The Agency for Healthcare Research and Quality has derived standardized care pathways for better patient outcomes. The rising investments in training healthcare providers are set to enhance treatment adherence by about 20-25% in the form of telehealth platforms like Teladoc. This supports advanced therapies and early detection programs, reducing long-term healthcare burdens. Also, public and private partnerships are gaining momentum, rendering a scalable model for future innovation.
• Development of Potent Biomarkers for Lymphangioleiomyomatosis: Vascular endothelial growth factor-D (VEGF-D) is the approved biomarker used for diagnosis that eliminates the requirement for lung biopsy in clinical settings. Despite its widespread adoption, VEGF-D concentrations are roughly 30% of patients, constraining the diagnosis of all LAM cases, thus, propelling the need for novel, safe, non-invasive, and specific biomarkers.
  In February 2023, the National Library of Medicine published a study on a serum assessment of extracellular matrix remodeling and angiogenesis in a patients cohort, comparing them with cystic lung disease (OCLD) patients and healthy women. 97 subjects were recruited, comprising 59 or 61% of LAM patients, 20 or 20% healthy female controls, and 18 or 19% of OCLD cases. A scoring method based on the cut-point of each VEGF-D and metalloproteinase-2 (MMP-2) was utilized to observe the diagnostic performance of the biomarker combination. MMP-2 was the only extracellular matrix remodeling biomarker able to differentiate LAM patients from OCLD and healthy patients. Serum MMP-2 was higher in LAM patients than in healthy controls and patients with OCLD. The specificity/sensitivity profiles of each biomarker (59/95% for VEGF-D, 54/92% for MMP-2) gave higher accuracy and a composite score (0.0069 × MMP-2+-6.36 + 0.0059 × VEGF-D) than each component alone. Therefore, the integration of VEGF-D and MMP-2 is likely to boost LAM diagnostic precision. A similar June 2023 report by the NCBI discussed the European Medicines Agency and FDA-approved Sirolimus. It is an mTOR inhibitor, known to control the excessive proliferation of smooth muscle cells in the lung parenchyma. In the MILEs trial, it showcased the capacity to sustain improvement in FVC and stabilization of FEV.

Challenges

• High Treatment Costs and Pricing Restraints: Treating lymphangioleiomyomatosis (LAM) comes at a heavy cost, often surpassing USD 50,000 per patient each year. In the United States, government support through Medicaid typically covers only about 25% to 30% of these expenses. That leaves a substantial number of patients either partially covered or entirely on their own to manage the financial burden. As treatment costs remain high, pharmaceutical companies are beginning to collaborate more actively with insurers and public health systems to create pricing strategies that make care more affordable. Novartis, for example, lowered the price of its treatment by 15% to 20% in 2023 in an effort to close the affordability gap. This decision not only made the drug more accessible to patients but also helped the company expand its presence in the market, with sales growing by 8.2% after the change.
