China Medical System: Pioneering Vitiligo Treatment in the Greater Bay Area

China Medical System (CMS) has made a significant stride in the treatment of vitiligo, a chronic skin condition characterized by depigmentation. On October 18, 2024, the first prescriptions of ruxolitinib phosphate cream, a novel treatment for vitiligo, were issued in the Greater Bay Area. This marks a substantial milestone in the region's healthcare landscape, as it brings hope to thousands of vitiligo patients seeking effective and innovative treatments.

Ruxolitinib cream, marketed as Opzelura, is a topical cream formulation of Incyte's selective JAK1/JAK2 inhibitor ruxolitinib. It is the first and only treatment for repigmentation approved for use in the United States, Europe, and now, the Greater Bay Area. The drug has demonstrated positive real-world study results in China, with a 49.5% F-VASI 75 response rate at week 24, significantly higher than the target value of 14.1% (p<0.0001). All secondary efficacy endpoints showed a trend of benefit consistent with the primary endpoint, and the treatment effect for vitiligo continued to improve with longer treatment duration.

The approval of ruxolitinib cream in the Greater Bay Area and Mainland China aligns with the global market size and growth for vitiligo treatments. The global vitiligo treatment market size is expected to reach USD 3.5 billion by 2027, growing at a CAGR of 7.5% during the forecast period (2020-2027). The demand for ruxolitinib cream in the region is driven by factors such as increasing awareness of the condition, a growing elderly population, and the rising demand for innovative and effective treatments.

The pricing strategy for ruxolitinib cream in China is expected to be competitive with its international pricing, considering the drug's innovative nature and the unmet medical needs it addresses. The competitive landscape for ruxolitinib cream in the Greater Bay Area and Mainland China includes off-label treatments such as topical corticosteroids (TCS) and calcineurin inhibitors (CI). However, these therapies have clinical deficiencies with long-term adverse reactions or limited efficacy. Ruxolitinib cream's approval as the first prescription drug for repigmentation in vitiligo in Mainland China positions it as a novel treatment option for Chinese vitiligo patients.

CMS has faced regulatory challenges in obtaining approval for ruxolitinib cream in the Greater Bay Area and Mainland China, similar to other regions like the US and Europe. The timeline for approval and market access in the region has been influenced by factors such as regulatory processes, data requirements, and local clinical trials. However, CMS has successfully navigated these challenges, with key milestones including the approval for Urgent Clinical Import by Hainan Medical Products Administration in August 2023 and the acceptance of the New Drug Application (NDA) for vitiligo indication by the National Medical Products Administration of China (NMPA) in September 2024.

The pricing and reimbursement strategy for ruxolitinib cream in the Greater Bay Area and Mainland China will play a crucial role in patient access and market growth. CMS is expected to work closely with healthcare providers, payers, and regulatory bodies to ensure that the drug is accessible and affordable for vitiligo patients in the region. The success of ruxolitinib cream in the Greater Bay Area and Mainland China will not only bring hope to vitiligo patients but also reinforce CMS's commitment to providing competitive products and services to meet unmet medical needs.
