Market Overview

Intrathecal drug administration is actually a route of administration that delivers the drug directly into the space filled with fluid around the spinal cord, called the intrathecal space. There is a need to administer therapeutics to the spinal space because some therapeutic drugs cannot gain systemic access to the spinal space or to the CNS because of the blood-brain barrier. In addition, there are advantages of delivery to the spinal space that include targeted delivery and rapid onset. Growth in the use of implantable infusion pumps and targeted drug therapies to maximize therapeutic efficacy and improve patient comfort. Also supporting demand are Japan's aging population and insurance reimbursement of intrathecal baclofen therapy. At the same time, high costs of treatment and the limited number of specialized centers for intrathecal therapy will continue to present obstacles to wider use of intrathecal therapies. The intrathecal drug market in Japan is expected to grow due to an increase in the prevalence of chronic pain conditions, cancer, and neurological diseases needing a more sophisticated approach to treating pain. For instance, the National Cancer Center predicts that approximately 1 million new cases of cancer will occur in 2023. It is anticipated that the increased demand for intrathecal medication administration for chemotherapy among cancer patients will result from the rising prevalence of cancer. The adoption of advances such as precision medicine, genetic profiling, and new drug delivery systems is also expected to drive growth in the market within the forecast years. In addition, the efforts made by large companies to improve their product portfolios through collaborations and other funding will lead to overall growth in the market.
