Prof. Howard Lee proposed health insurance reimbursement for the combination therapy of DPP4 inhibitors and SGLT2 inhibitors, irrespective of their labels as approved by the Korea Ministry Food and Drug Safety (MFDS), at a special session organized by the Korean Diabetes Association (KDA), in association with its Spring Conference 2019, held on May 9-11, 2019, at the HICO, Kyeongju, Korea. Unlike other countries including the USA, EU, and Japan, MFDS in Korea has approved the combination therapy of SGLT2 inhibitors with other oral hypoglycemic agents, particularly with DPP4 inhibitors, only on the basis individual drugs, not on the therapeutic class. This unique regulatory approval has contributed to the delayed reimbursement of various combination therapies involving SGLT2 inhibitors since their approvals.
The delayed reimbursement has caused a lot of debates not only between the pharmaceutical industry and the Health Insurance Review and Assessment Service or HIRA, but also among clinicians. With this background, the KDA asked Prof. Lee to share his perspectives from the points of drug regulatory science if the reimbursement for the combination therapy of DPP4 inhibitors and SGLT2 inhibitors on the basis of therapeutic class, not on the individual drug, has any scientific and clinical rationale. Prof. Lee, based on an intensive systematic literature review focusing on the pharmacokinetics, drug-drug interactions, clinical efficacy, and safety profiles of the combination treatment with DPP4 inhibitors and SGLT2 inhibitors, discussed that it is highly unlikely any combination of the two classes would interact in a clinically meaningful and significant way. Furthermore, Prof. Lee argued that it is very likely for every combination of a DPP4 inhibitor with an SGLT2 inhibitor to result in an additional, significant, and clinically meaningful decrease in HbA1c or glycated hemoglobin. However, since not every combination has been studied for its safety profiles although it is likely to be similar to those of monotherapy, Prof. Lee proposed to perform a real world data study under the auspice of KDA, sponsored by the pharmaceutical industry, to explore and confirm the safety and efficacy profiles of the combination therapy.
Reflecting the interest in the reimbursement issue, the conference room was full of clinicians, industry representative, and journalists even though the session was presented early in the morning on Saturday. More detailed information on the session can be found here.
