2. Market Dynamics and Drivers
2.1 Increasing Incidence of Skin Cancers and Viral Warts
Rising UV exposure, aging populations, and changing lifestyles are fueling skin cancer (notably actinic keratosis and basal cell carcinoma) globally. According to the WHO, non-melanoma skin cancers account for approximately 2.7 million cases annually [2]. External genital warts, caused predominantly by HPV types 6 and 11, display a steady increase, especially among sexually active populations.
2.2 Expanding Therapeutic Approvals and Off-Label Use
Regulatory agencies such as FDA and EMA have approved imiquimod for multiple indications, facilitating broader adoption. Off-label uses, such as treatment of molluscum contagiosum, further expand the market potential.
2.3 Patent Expirations and Generic Competition
Imiquimod’s key patents, initially held by 3M, expired in multiple jurisdictions around 2018-2020. Generic entries have since increased price competition and accessibility, especially in emerging markets.
