Ruxolitinib Cream is a topical JAK inhibitor, selectively inhibiting Janus kinase 1 and 2 (JAK1/JAK2), with composition patent, formulation patent and use patent in the main Territory.

Ruxolitinib Cream (Opzelura™) is the first and only topical JAK inhibitor approved by the U.S. Food and Drug Administration (FDA). In July 2022, Ruxolitinib Cream was approved for the topical treatment of patients with nonsegmental vitiligo aged 12 years and older. It is the first and only product approved by the FDA for vitiligo patient repigmentation. Two pivotal clinical studies showed that after 24 weeks of treatment, compared with vehicle (non-medicated cream), the facial and total body repigmentation of patients treated with Ruxolitinib Cream was significantly improved, and 52-week data showed continuous improvement in repigmentation with the extension of treatment.

Previously, Ruxolitinib Cream was approved by the FDA in September 2021 for the topical short-term and non-continuous chronic treatment of mild to moderate atopic dermatitis (AD) in non-immunocompromised adult and pediatric patients 12 years of age and older whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable. Two pivotal studies showed that treatment with Ruxolitinib Cream resulted in a significant proportion of patients who achieved the primary efficacy endpoint of clear or almost clear and a significant reduction in pruritus compared to the vehicle group.

Furthermore, Ruxolitinib Cream is being evaluated for other immune-mediated dermatologic diseases such as lichen planus and lichen sclerosus.

Vitiligo is a chronic autoimmune disease characterized by depigmentation of the skin, which results from the loss of pigment-producing cells known as melanocytes. It is estimated that there are approximately 14 million vitiligo patients and 6.5 million in China and the eleven Southeast Asian countries respectively. Non-segmental vitiligo patients account for approximately 85% of them. The existing topical therapies of corticosteroids (TCS) and calcineurin inhibitor (TCI) are used off-label, and have clinical pain points with long-term adverse reactions or limited efficacy.

AD is a chronic, recurrent and inflammatory dermatologic disease, with the main clinical manifestations of dry skin, chronic eczema-like lesions and obvious itching or pruritus, which may seriously affect the quality of life of patients. It is estimated that there are approximately 26 million AD patients in China, of whom about 23 million are mild to moderate; there are approximately 19 million AD patients in the eleven Southeast Asian countries, of whom about 16 million are mild to moderate. Topical drugs are the most basic treatment for AD. Traditional topical medications such as TCS and TCI have clinical pain points with long-term adverse reactions or limited efficacy, therefore novel treatments are urgently needed, especially for those mild to moderate AD patients who do not need systemic treatment.
