Restraint/Challenge

Concerns Regarding Adverse Effects and High Treatment Costs

• Despite their clinical benefits, concerns surrounding the potential adverse effects of immunomodulators pose a significant challenge to broader market penetration. Long-term use can sometimes lead to immune suppression, increasing the risk of infections, cancers, or other complications, which raises caution among both patients and healthcare providers
  • For instance, studies have reported that certain immunosuppressants, while effective in disease management, can make patients more vulnerable to opportunistic infections, thereby requiring close monitoring and limiting their use in some populations
• Addressing these safety concerns through the development of next-generation therapies with improved safety profiles and targeted delivery mechanisms is crucial for increasing patient confidence and treatment uptake
• In addition, the relatively high treatment costs of advanced immunomodulators compared to traditional drugs can be a barrier to adoption, particularly in developing regions with limited healthcare budgets or among patients without robust insurance coverage
• While biosimilars are helping to reduce costs and expand accessibility, the perceived premium pricing for cutting-edge biologics and novel immunotherapies continues to hinder widespread adoption, especially in price-sensitive markets
• Overcoming these challenges through healthcare reimbursement reforms, increased production of cost-effective biosimilars, and continuous R&D for safer formulations will be vital for ensuring sustained market growth and broader patient access
