    In less than ten days, a number of first imitation blockbuster listings.

    CSPC's first imitation approved

    On April 1, CSPC announced that the “Amphotericin B Cholesterol Sulfate Complex for Injection” developed by its subsidiary CSPC Ouyi Pharmaceutical Co., Ltd. had obtained the approval for drug registration issued by the China Food and Drug Administration. The first imitation of this variety goes on the market.

    Amphotericin B is a polyene antifungal antibiotic with no drug resistance problem. It is the last line of defense for the treatment of fungal infections. It is also a powerful broad-spectrum antifungal drug. Because of its poor water solubility, early products were solubilized with sodium deoxycholate , This kind of product has high nephrotoxicity, which limits the clinical application.

    Compared with the amphotericin B for injection currently used in clinical practice in China, the amphotericin B complex can significantly reduce nephrotoxicity, thereby increasing the dose and increasing the therapeutic index. The approval of the product will give more patients the opportunity to receive treatment and cure, and obtain a better survival prognosis.

    In general, amphotericin B complex is suitable for a wide range of people and has a huge market potential. According to the analysis of Everbright Securities, according to the "Epidemiological Trends of Fungal Infections in China", the total number of patients with deep fungal infections in China is estimated to be 600,000 to 700,000. It is assumed that amphotericin B complex applies to 1/3 of the population, and the average person is 3 per day. The treatment cycle is 14 days, and the estimated demand is more than 8 million per year. Assuming that the company's product is priced at 500 yuan per stick and penetrates more than 40% of the applicable people, the annual sales peak of this variety is expected to exceed 1.5 billion yuan, and the market prospect is broad.

    In November 2019, CSPC Ouyi's Amphotericin B Cholesterol Sulfate Complex for Injection was included in the priority review process due to urgent clinical needs and market shortages. After this approval, the market performance is worth looking forward to.

    It can be seen that, driven by policies and other favorable factors, in addition to innovative drugs, China's research and development in the first generic drugs has also been in full swing in recent years.

Under the background of accelerating the replacement of original research by generic drugs, after the first generic drugs are launched, they are expected to quickly occupy the market and have a good market performance.

    Therefore, in addition to the layout of innovative drugs, the first imitation has also become the development direction of the current pharmaceutical companies. It is believed that with the approval of generic drugs by many pharmaceutical companies, the relevant drug market will usher in a round of reshuffle.
