Group 1: Collaboration Agreement - The agreement includes three products: Rykotan (injectable risperidone microspheres), Rybale (paliperidone palmitate injection), and Meibiri (paliperidone palmitate injection), all intended for the treatment of schizophrenia [1]. - Enhua will be responsible for the exclusive distribution and commercialization of these products in mainland China, while Green Leaf retains ownership of the assets, registration certificates, and all intellectual property rights [1]. - Enhua will pay a non-refundable licensing fee of $20 million to Green Leaf upon signing the agreement, which has a duration of ten years [1]. Group 2: Market Context and Product Development - Schizophrenia is a chronic and highly recurrent disease, with approximately 8 million patients in China, making treatment adherence a significant challenge [2]. - Long-acting injectable antipsychotics, such as those developed by Green Leaf, significantly improve patient compliance compared to oral formulations, serving as an important strategy to prevent relapse [2]. - Rykotan is noted as China's first independently developed long-acting injectable second-generation antipsychotic, while Rybale is the world's first and only paliperidone long-acting injection with a "one injection in the first month" dosing regimen [2]. Group 3: Strategic Importance - The board believes that the three long-acting injectables create a differentiated product portfolio that addresses the treatment needs of schizophrenia patients across all stages of the disease [3]. - The CNS (central nervous system) sector is a core strategic area for Green Leaf, which possesses a competitive product matrix and platform capabilities in this field [3]. - The collaboration with Enhua aims to deepen the market presence in the CNS sector, particularly enhancing product coverage in primary healthcare centers to help more patients receive standardized treatment and reduce the burden of the disease [3].
