引言
安进公司(Amgen Inc.)作为全球领先的生物技术公司,正面临着前所未有的专利悬崖挑战。截至 2025 年 10 月 21 日,公司股价为 300.18 美元,总市值达 1616.05 亿美元(1),位列全球第 14 大制药公司。然而,这家成立于 1980 年、拥有超过 21,000 名员工的行业巨头,其核心产品组合正处于关键的专利到期期。
专利悬崖的严峻性不容忽视。根据最新数据,2025-2030 年间,全球将有价值约 3500 亿美元的药物失去专利保护,其中前 20 大制药公司承担了 80% 的收入损失风险(149)。对安进而言,其九款核心产品将在 2021-2030 年间陆续失去专利保护,其中Prolia/Xgeva 和 Otezla 合计占公司 2025 年预计总收入的 41%(125)。更令人担忧的是,公司面临 67% 的收入风险,前四大产品均面临专利到期威胁(132)。
本研究旨在深入分析安进公司如何应对这一关键挑战,重点关注其核心产品专利到期后的市场影响、生物类似药竞争格局,以及公司的战略转型措施。通过对公司财务数据、产品管线、研发投入和并购策略的全面评估,我们将揭示安进能否成功跨越专利悬崖,维持其在生物技术领域的领导地位。
一、安进核心产品专利到期全景图
1.1 专利到期时间轴与市场分布
安进的专利悬崖呈现出集中爆发的特征,主要集中在 2025-2028 年这一关键时期。根据最新的专利到期数据,各核心产品的专利保护情况如下:
已到期产品:
•Enbrel(依那西普):物质专利于 2012 年到期,但通过制剂和制备方法专利的扩展,目前活性组分制备专利期已延长至 2029 年,制剂专利期最长延长至 2034 年(12)。在美国市场,Enbrel 的新专利将于 2028 年 11 月 22 日到期,届时该药物将已上市 30 年(16)。
2025 年到期产品:
•Prolia/Xgeva(地诺单抗):主要专利已于 2025 年 2 月到期(6)。在美国,专利到期日为 2025 年 2 月 19 日;在欧洲,除法国、意大利、西班牙和英国外,其他国家已于 2022 年 6 月 25 日到期,而这四个主要市场将在 2025 年到期。
•Kyprolis(卡非佐米):治疗方法专利已于 2025 年 4 月 14 日到期,而化合物专利将于 2027 年 12 月 7 日到期(19)。
2026-2028 年到期产品:
•Xgeva:作为地诺单抗的另一个品牌,将于 2026 年到期(101)。
•Otezla(阿普米司特):专利原定于 2024 年到期,但获得了超过 3 年的专利延期,现定于 2028 年 2 月 16 日到期(23)。法院裁决阻止了仿制药制造商在 2028 年前销售仿制药(8)。
•Enbrel:核心专利将于 2028 年到期(101)。
•Repatha(依洛尤单抗):专利将于 2028 年 8 月到期(29)。
1.2 生物类似药获批与上市情况
随着专利到期,生物类似药的竞争格局正在快速形成。截至 2025 年 6 月,安进核心产品的生物类似药获批情况如下:
地诺单抗(Prolia/Xgeva)生物类似药:
•Sandoz 的 Jubbonti®/Wyost® 已于 2025 年 6 月 2 日在美国上市,成为首个获批的可互换生物类似药(72)。根据与安进的和解协议,Sandoz 可于 2025 年 5 月 31 日或更早上市(76)。
•在欧洲,已有三家公司的生物类似药获批:Celltrion 的 Stoboclo®/Ozenvelt®(2025 年 2 月)、Samsung Bioepis 的 Obodence™和 Xbryk™(2025 年 2 月)以及 Sandoz 的产品(2024 年 5 月)(74)。
依那西普(Enbrel)生物类似药:
•Sandoz 的 Erelzi® 早在 2016 年 8 月就获得了 FDA 批准,但由于专利诉讼,预计要到 2029 年才能在美国上市(50)。
•Samsung Bioepis 的 Eticovo® 于 2019 年 4 月获批,但同样受到专利限制。
其他产品的生物类似药进展:
•Repatha:已有生物类似药在研,如 Henlius 开发的 evolocumab 生物类似药,但仍在专利保护期内(78)。
•Blincyto:Teva 和武田正在开发生物类似药,计划 2026 年进入市场,目前正在进行分子验证研究(84)。
二、专利到期对核心产品的市场冲击分析
2.1 Enbrel:从巅峰到衰退的转折
Enbrel 作为安进的明星产品,其市场表现的变化最能体现专利到期和生物类似药竞争的影响。根据公司财报数据,Enbrel 的销售趋势呈现出明显的下滑态势:
•2022 年:销售额 36.97 亿美元(122)
•2023 年:销售额 36.97 亿美元(122)
•2024 年:销售额 33.2 亿美元,同比下降 10%(63)
•2025 年 Q1:销售额 5.1 亿美元,同比下降 10%(124)
•2025 年 Q3:销售额 8.25 亿美元,同比下降 20%,主要由 13% 的销售扣除和 12% 的价格下降驱动(115)
欧洲市场的惨烈教训为美国市场提供了预警。在欧洲,安进已经失去了约 25% 的市场份额给 Samsung Bioepis 的生物类似药。法国市场的数据更为惊人,etanercept 生物类似药的渗透率已达 74%。价格方面,欧洲市场的生物类似药竞争导致 Enbrel 和同类产品价格下降了 30%-50%(66)。
辉瑞作为 Enbrel 的共同开发者,其分得的收入也呈现下滑趋势。2024 年辉瑞从 Enbrel 分得 6.90 亿美元,同比下降 17%(58),这进一步印证了该产品面临的市场压力。
2.2 Prolia/Xgeva:下一个面临冲击的重磅产品
Prolia 和 Xgeva 作为地诺单抗的两个品牌,合计占安进 2023 年销售额的 22% 以上(1),是公司的第一大收入来源。2024 年的数据显示:
•Prolia 全年销售额 40.48 亿美元(122)
•2025 年 Q4 销售额 12 亿美元,全年 37.9 亿美元
•2025 年 Q1 销售额 11.7 亿美元,同比增长 5%
然而,随着 2025 年 2 月专利到期和 Sandoz 生物类似药的上市,Prolia/Xgeva 的销售前景堪忧。安进管理层在 2025 年 Q1 财报会议上明确指出,预计 2025 年下半年将出现销售侵蚀(128)。考虑到 Enbrel 在欧洲市场的经验,Prolia/Xgeva 可能面临类似的市场份额损失。
2.3 其他核心产品的风险评估
除了 Enbrel 和 Prolia/Xgeva,安进的其他核心产品也面临不同程度的专利到期风险:
Otezla(阿普米司特):
•2024 年销售额 21.88 亿美元(122)
•占 2024 年产品销售额的 6.73%
•虽然专利延期至 2028 年,但已面临激烈的市场竞争,2024 年销售额下降 3%,主要由 8% 的价格下降驱动
Repatha(依洛尤单抗):
•2024 年销售额 22.2 亿美元,同比增长 36%(121)
•占 2024 年产品销售额的 7.58%
•作为 PCSK9 抑制剂,技术结构相对清晰,未来可能面临生物类似药挑战(77)
Kyprolis(卡非佐米):
•2024 年销售额 14.03 亿美元(122)
•占 2024 年产品销售额的 4.32%
•虽然治疗方法专利已到期,但化合物专利保护至 2027 年 12 月,短期内风险相对可控
三、安进的战略应对:多管齐下的转型之路
3.1 重磅收购:通过外延式增长填补专利悬崖
面对专利悬崖,安进采取了激进的并购策略。2023 年 10 月,公司以 278 亿美元收购 Horizon Therapeutics,这是安进历史上最大的一笔收购(101)。这笔交易的战略意图十分明确:通过获得罕见病药物来弥补核心产品专利到期带来的收入损失。
Horizon 带来的核心资产:
•Tepezza(teprotumumab-trbw):甲状腺眼病治疗药物,2024 年销售额达 18.5 亿美元(139),成为安进新的增长引擎。2024 年 Q4 销售额 4.6 亿美元,全年近 19 亿美元(114)。
•Krystexxa(pegloticase):痛风治疗药物,2024 年 Q3 销售额 3.1 亿美元,同比增长 116%。安进在全球静脉用 pegloticase 市场占据 60-65% 的份额(119)。
•Uplizna(inebilizumab-cdon):视神经脊髓炎谱系疾病治疗药物,2024 年 Q4 销售额 1.01 亿美元,全年 3.79 亿美元。
•Tavneos(avacopan):抗中性粒细胞胞浆抗体相关性血管炎治疗药物,2024 年 Q4 销售额 8100 万美元,全年 2.96 亿美元,同比增长 111%。
通过这笔收购,安进在 2024 年 Q3 实现了 12 亿美元的罕见病产品销售额,这些产品大多处于生命周期早期,有望在未来几年持续增长(115)。
3.2 创新研发:押注下一代重磅产品
在内部研发方面,安进展现出了强大的创新能力和资金实力。2024 年,公司研发投入达到创纪录的 60 亿美元,同比增长 25%(108)。公司的研发策略结合了人类遗传学、蛋白质工程和人工智能等前沿技术(106)。
最具潜力的在研产品:MariTide(AMG 133)
MariTide 是安进在减肥药市场的重磅赌注。作为一种长效肽 - 抗体偶联物,每月或更少频率给药,在 2025 年 6 月公布的 Phase 2 研究中展现出令人瞩目的效果:
•非糖尿病肥胖患者:52 周平均体重减轻高达 20%,安慰剂组仅为 2.6%
•糖尿病肥胖患者:52 周平均体重减轻高达 17%,安慰剂组仅为 1.4%
•更重要的是,52 周时体重减轻尚未达到平台期,提示有进一步减重潜力
MariTide 的差异化优势在于其给药频率。与诺和诺德的 Wegovy(每周注射)相比,MariTide 的每月给药方案有望显著提高患者依从性。目前,公司正在进行 72 周的 Phase 3 MARITIME 慢性体重管理研究,并计划在 2025 年启动动脉粥样硬化性心血管疾病、心力衰竭和阻塞性睡眠呼吸暂停的 Phase 3 研究。
其他重要研发进展:
•IMDELLTRA(tarlatamab-dlle):2024 年 5 月获得 FDA 加速批准用于广泛期小细胞肺癌,2024 年 Q3 销售额 3600 万美元,季度环比增长 200%(110)
•Tezspire(tezepelumab-ekko):哮喘治疗药物,2024 年 Q3 销售额 2.69 亿美元,同比增长 67%
•Evenity(romosozumab-aqqg):骨质疏松治疗药物,2024 年 Q3 销售额 3.99 亿美元,同比增长 30%
3.3 生物类似药布局:从防守到进攻
面对生物类似药的威胁,安进采取了 **"以其人之道还治其人之身"** 的策略,积极布局生物类似药业务。公司利用其在生物制剂领域的丰富经验,开发了多款生物类似药:
•2024 年,安进的生物类似药销售额达到 7 亿美元,同比增长 35%
•成功推出了强生 Stelara 的生物类似药 Wezlana,标志着公司在生物类似药领域的突破(140)
•继续扩大在肿瘤学和自身免疫疾病领域的生物类似药组合
这种策略不仅能够部分抵消原研药专利到期的影响,还能为公司开辟新的收入来源。
3.4 产品组合优化:聚焦高增长领域
安进正在重新平衡其产品组合,减少对即将失去专利保护产品的依赖,加大对高增长领域的投入:
重点发展领域:
1.罕见病:通过 Horizon 收购,罕见病已成为公司重要的增长引擎。预计到 2030 年,罕见病药物可能贡献公司收入的 25%(126)。
2.肿瘤学:IMDELLTRA、Blincyto 等创新产品展现出强劲增长势头。2024 年,10 个产品实现双位数增长,包括多款肿瘤药物(116)。
3.代谢疾病:MariTide 有望在 2030 年达到 1000 亿美元的肥胖药物市场中占据重要份额。
产品生命周期管理:
•为即将到期的产品寻找新适应症,如 Otezla 在 2024 年获批用于中重度斑块型银屑病(89)
•开发新剂型和给药方案,如 Enbrel 的每周给药方案(44)
•通过价格策略和患者支持项目维持市场份额
四、财务影响的量化评估与前景展望
4.1 专利悬崖的财务冲击预测
基于各产品的销售占比和专利到期时间,我们可以对安进未来几年的财务影响进行量化分析:
短期影响(2025-2026 年):
•Prolia/Xgeva 占 2025 年预计收入的 22% 以上(1),随着生物类似药上市,预计将出现 30-50% 的销售下滑
•Enbrel 占 2024 年销售额的 10.3%(121),已呈现加速下滑趋势,2025 年 Q1 同比下降 10%(124)
•管理层预计 2025 年下半年将出现明显的销售侵蚀,但新增长将抵消大部分损失
中长期影响(2027-2030 年):
•到 2030 年,安进面临 67% 的收入风险,前四大产品均将失去专利保护(132)
•九款产品将在 2021-2030 年间失去专利保护,累计影响可能超过 100 亿美元
4.2 新增长引擎的贡献评估
尽管面临专利悬崖,安进的新增长引擎正在加速运转:
2024 年业绩亮点:
•总收入 334.24 亿美元,同比增长 19%(123)
•产品销售增长 19%,主要由 23% 的销量增长驱动(123)
•21 个产品创下销售记录(123)
•自由现金流 104 亿美元,同比增长 41%(123)
2025 年展望:
公司对 2025 年保持谨慎乐观,预计:
•总收入 343-357 亿美元
•非 GAAP 每股收益 20.00-21.20 美元
•生物类似药销售额预计达到 10 亿美元以上
4.3 关键成功因素与风险提示
成功跨越专利悬崖的关键因素:
1.MariTide 的市场成功:作为潜在的重磅产品,MariTide 需要在 2026-2027 年成功上市并快速放量,以弥补 Enbrel 和 Prolia/Xgeva 的收入损失。
2.罕见病产品的持续增长:Tepezza、Krystexxa 等产品需要保持高速增长,特别是 Tepezza 需要从目前的 18.5 亿美元增长到 30 亿美元以上。
3.生物类似药业务的扩张:需要从目前的 7 亿美元增长到 20 亿美元以上,成为重要的收入来源。
4.研发管线的执行力:需要持续推出创新产品,特别是在肿瘤学和罕见病领域。
主要风险因素:
1.竞争加剧:在肥胖药物市场,诺和诺德和礼来已经建立了强大的先发优势,MariTide 面临激烈竞争。
2.监管风险:新药审批的不确定性,特别是对于创新药物如 MariTide。
3.执行风险:大规模并购的整合挑战,以及新产品上市的商业化风险。
4.宏观环境:美国《通胀削减法案》的价格谈判压力,可能影响新产品的定价策略。
结语
安进公司正站在一个关键的十字路口。专利悬崖的挑战是严峻的,2025-2028 年间,公司将失去多款核心产品的专利保护,预计将影响超过 100 亿美元的年收入。Enbrel 在欧洲市场的教训表明,生物类似药的冲击可能比预期更加猛烈。
然而,安进的应对策略是全面而富有远见的。通过 278 亿美元收购 Horizon,公司成功获得了 Tepezza 等极具潜力的罕见病药物;通过 60 亿美元的研发投入,培育了 MariTide 等下一代重磅产品;通过生物类似药布局,实现了从防守到进攻的转变。更重要的是,公司正在从一家以成熟产品为主的传统生物技术公司,转型为以创新和罕见病为驱动的新型生物制药企业。
对投资者的建议:
安进的股票在短期内可能面临波动,特别是 2025 年下半年 Prolia/Xgeva 生物类似药全面上市后。但从长期来看,公司的转型战略是正确的。建议投资者关注以下几个关键指标:(1) MariTide 的临床进展和商业化前景;(2) Tepezza 等罕见病产品的增长轨迹;(3) 生物类似药业务的扩张速度;(4) 研发管线中其他创新产品的进展。
对行业观察者的启示:
安进的转型之路为整个生物技术行业应对专利悬崖提供了重要借鉴。成功的关键在于:(1) 提前布局,通过并购快速获得新的增长引擎;(2) 持续创新,保持强大的研发能力;(3) 灵活应变,在生物类似药时代找到新的商业模式;(4) 聚焦优势,在核心治疗领域建立领导地位。
对公司管理层的建议:
1.加快 MariTide 的开发和上市进程,确保其成为新的增长支柱。
2.深化与医疗机构和支付方的合作,确保新产品的市场准入。
3.优化成本结构,提高运营效率,为转型期提供财务缓冲。
4.加强人才管理,特别是在创新研发和商业化领域吸引顶尖人才。
总的来说,虽然专利悬崖是安进面临的最大挑战,但公司已经展现出了强大的战略定力和执行能力。如果能够成功执行既定战略,安进有望在 2030 年后以一个更加强大和多元化的姿态出现在全球生物制药舞台上。正如公司 CEO Robert Bradway 所说:"2024 年销售和收益的强劲增长反映了我们业务的发展势头。凭借全球强劲表现,我们正在大力投资快速推进的管线,专注于在四个治疗领域提供创新疗法。"(123) 这种信心并非毫无根据,而是建立在扎实的战略布局和执行能力之上。
