Biliary tract cancer is known to have the highest mortality and incidence rates in Korea in the world. It is also one of the most difficult cancers to treat in Korea due to the limited options, or ‘weapons’ available to doctors in practice.

However, immuno-oncology drugs are being approved for the first-line treatment of biliary tract cancer and are emerging as an alternative in the field.

As a result, the issue of ‘reimbursement’, which remains the biggest obstacle to the utilization of such treatment, is emerging as an issue. Attention is focused on whether Imfinzi, which the company planning to reapply for reimbursement this year, will be able to overcome this hurdle.
