Restraint/Challenge

“Drug Resistance Development and High Treatment Costs”

• A significant challenge to broader market penetration for PARP inhibitors is the development of drug resistance in cancer cells, alongside the relatively high cost of treatment. While PARP inhibitors initially show promising results, cancer cells often develop mechanisms to circumvent their effects over time, limiting long-term efficacy and leading to disease progression. This acquired resistance is a major concern for both patients and healthcare providers
  • For instance, studies have identified various mechanisms of resistance, such as secondary mutations in BRCA genes that restore DNA repair function, increased drug efflux, or changes in other DNA repair pathways. These biological hurdles necessitate continuous research into overcoming resistance and developing novel combination therapies
• Addressing these challenges requires substantial investment in biomarker discovery to better select patients who will respond to therapy and in research to understand and counteract resistance mechanisms
• Furthermore, the high initial cost of PARP inhibitor therapies poses a significant barrier to access, particularly in regions with limited healthcare budgets or for patients without adequate insurance coverage. While these drugs offer significant clinical benefits, their premium pricing can limit widespread adoption and create financial burdens on healthcare systems and individuals
• Overcoming these challenges through intensive research into resistance mechanisms, development of more accessible and affordable formulations, and robust payer negotiations for reimbursement will be vital for sustained market growth and ensuring wider patient access to these life-saving therapies
