Innovative Payment Models for Sickle-Cell Disease Gene Therapies in Medicaid: Leveraging Real-World Data and Insights from CMMI’s Gene Therapy Access Model

Article

作者: McQueen, R Brett ; DiStefano, Michael J ; Nair, Kavita ; Wright, Garth C ; Leonard, Jim ; Zemplenyi, Antal ; Anderson, Kelly E

OBJECTIVEThis study aims to evaluate the financial implications of implementing various payment models, including outcome-based agreements (OBAs), volume-based rebates, and guaranteed rebates, for the newly approved gene therapies, exagamglogene autotemcel (exa-cel) and lovotibeglogene autotemcel (lovo-cel), in the treatment of sickle-cell disease (SCD) from the perspective of Colorado Medicaid. The analysis specifically examines the cost of standard of care (SoC) for severe SCD, the impact of different eligibility criteria based on vaso-occlusive events (VOEs), and the potential financial impacts associated with rebate structures.METHODSData from the Colorado Department of Health Care Policy & Financing (HCPF) database was used to estimate the annual costs for Medicaid-enrolled patients with severe SCD from 2018 to 2023. Patients were selected based on various eligibility criteria, including the number of VOEs, acute chest syndrome events, and stroke diagnoses. Three-state Markov models (SCD, stable, and dead) were constructed to compare the costs of SoC and gene therapies. The durability of gene therapy effectiveness and the financial impact of OBAs, volume-based rebates, and guaranteed rebates were evaluated over a 6-year contract period, with scenarios reflecting different VOE criteria and treatment durability.RESULTSThe average annual SoC cost for severe SCD patients (N = 138) was US$45,941 (SD US$59,653), with higher costs associated with more frequent VOEs. Gene therapies exa-cel and lovo-cel, with one-off list prices of US$2.2 million and US$3.1 million, respectively, exhibited high upfront costs, resulting in a negative cumulative balance averaging - US$2.11 million for exa-cel and - US$3.00 million for lovo-cel per patient over 6 years compared with SoC. Outcome-based rebates could potentially save Medicaid approximately US$260K (uncertainty interval 88K-772K) per patient on average for exa-cel and US$367K (uncertainty interval 122K-1111K) for lovo-cel after they pay the full up-front cost. Volume-based and guaranteed rebates also offered potential savings but varied in impact based on contract duration and effectiveness of gene therapy.CONCLUSIONSThe study highlights critical considerations for Medicaid in negotiating OBAs for SCD gene therapies. Achieving budget neutrality over 6 years is unlikely due to low SoC costs. However, payment models can enhance value-based spending by linking high therapy costs and potential rebates to the health gains these treatments may offer. OBAs offer offsets contingent on therapy effectiveness durability and contract terms (such as length and price), while varying eligibility criteria impact budgets and outcomes. Medicaid real-world data is crucial for navigating complexities in defining eligible populations and structuring OBAs.

Impact of Different Definitions of Vaso-Occlusion on Efficacy Assessments in Sickle Cell Disease Clinical Trials

Review

作者: Locatelli, Franco ; Xuan, Fengjuan ; Imren, Suzan ; Li, Nanxin ; Eckrich, Michael J ; Frangoul, Haydar ; Grupp, Stephan A

INTRODUCTIONPatients with sickle cell disease (SCD) experience recurrent, severe pain events due to vaso-occlusion. Eliminating these acute pain events is a key outcome in SCD clinical trials; however, the definition of a vaso-occlusive crisis (VOC) or a vaso-occlusive event (VOE) has not been consistently applied, hampering comparisons of treatment efficacy between different therapeutic approaches. We have examined the degree to which differing definitions of vaso-occlusion in clinical trial endpoints impact efficacy outcomes.METHODSDescriptions of clinical endpoints related to vaso-occlusion and pain events were reviewed from trials of exagamglogene autotemcel (exa-cel), lovotibeglogene autotemcel (lovo-cel), renizgamglogene autogedtemcel (reni-cel), hydroxyurea, L-glutamine, voxelotor, and crizanlizumab. Patient-level data from the published exa-cel Phase 3 pivotal trial (CLIMB SCD-121; data cut 14 Jun 2023) was used to evaluate efficacy outcomes based on differing endpoint definitions of vaso-occlusion.RESULTSIn the seven clinical trials reviewed, definitions of vaso-occlusion and/or pain events varied by care setting, duration of care, treatments used, and associated complications, with the frequency and duration of medical facility visits for acute pain events being most dissimilar between trials. Definitions of severe VOCs (exa-cel), VOC (voxelotor), and sickle cell-related pain crises (SCPCs; crizanlizumab and L-glutamine) included pain events requiring a medical facility visit of any duration, whereas the definition of painful crises (hydroxyurea) required a medical facility visit of > 4 h and the definition of severe vaso-occlusive events (VOEs; lovo-cel and reni-cel) required a hospital or emergency room (ER) observation unit visit lasting ≥ 24 h or ≥ 2 visits to a day unit or ER over a 72-h period. Based on the definition of severe VOCs, 29/30 patients [96.7%; 95% confidence interval (CI): 82.8, 99.9] in the CLIMB SCD-121 trial were considered free from severe VOCs for ≥ 12 consecutive months, whereas when the severe VOEs definition was applied to the same data, all patients (30/30; 100.0%; 95% CI: 88.4, 100.0) were considered free from severe VOEs for ≥ 12 consecutive months.CONCLUSIONDifferences exist in definitions of vaso-occlusion and pain events used in SCD clinical trials. Severe VOCs (exa-cel), VOC (voxelotor), and SCPCs (crizanlizumab and L-glutamine) were more broadly inclusive than severe VOEs (lovo-cel and reni-cel) or painful crisis (hydroxyurea). Clinically, these differences resulted in differing numbers of patients being considered free from vaso-occlusion pain events, underscoring the challenge in comparing frequencies of pain events across SCD clinical trials.

Sickle cell disease gene therapy drug expenses and reimbursement: a litmus test for commercial pricing strategy and patient access for curative therapies

Article

作者: Galipeau, Jacques ; Hume, Ashley ; Grilley, Bambi J

Durable gene therapies newly approved by the Food and Drug Administration for sickle cell disease offer the promise of cure with subsequent improvement in quality of life through avoidance of repeated hospitalizations and worsening of disabilities in these patients. In the United States, following Food and Drug Administration approval, lovotibeglogene autotemcel (Lyfgenia, bluebird bio, Inc, Sommerville, MA, USA) and exagamglogene autotemcel (Casgevy, Vertex Pharmaceuticals Inc, Boston, MA, USA) were launched in 2024 for treatment of patients 12 years and older with frequent vaso-occlusive crises. Here we will discuss the first treatment with lovotibeglogene as a test case serving to highlight the multiple drug reimbursement pathways in the United States for cell and gene products for orphan disorders and their impact on patient adoption and access.

天价CGT疗法的支付博弈：美国医保如何不为无效治疗买单？

当大西洋两岸的德国与美国几乎同时为CGT疗法支付开创新模式，又将为中国的医保支付改革带来怎样的借鉴与启示？撰文| 杨景雄孔凡懿石洣珏在各国医疗费用持续攀升与技术迭代加速的双重挑战下，医疗支付体系的改革已成为全球性挑战。因此，针对全球公认的昂贵创新疗法CGT，各国都进行了不同的尝试。近期，CSL公司就和德国医保机构达成了一个创新付费协议：天价基因药Hemgenix不用提前全款买单，而是“治好了再付钱”，开创了一种全新的“风险分担”模式。具体来说，医保每年会根据实际治疗效果支付药费，如果治疗失败（比如患者又需要打原来的凝血针），药企就得自己承担损失，医保不用付钱。远在大西洋另一边的美国，即使作为世界最大的医疗市场，也未能避开昂贵CGT疗法给传统医保支付模式带来的严峻挑战。面对这一压力，美国医疗保险和医疗补助服务中心（Centers for Medicare & Medicaid Services, CMS）决定对既有支付体系框架进行改革，在2024年12月启动了CGT医保支付创新试点。简单来说就是启动了 “集中谈判+按疗效支付”的新模式，针对罕见病基因疗法，联邦政府直接和药企谈全国统一价，接受治疗的患者越多，药企返利越多，还派技术团队盯疗效，治不好药企还得退钱。无论是德国的“治好了再付钱”，还是美国的“治不好退钱”的CGT疗法支付新模式，其实都暗示出一个不约而同的全球性变革趋势：面对医疗技术迭代加速带来的成本压力，其定价机制逐步从市场导向转向政府主导按价值付费。当然，这也为中国探索贵价创新疗法支付机制提供了参考，在基本医保支付能力有限的情况下，如何平衡创新激励与医保可持续性？如何通过支付机制设计提升医疗公平？美国CGT医保支付试点：“治不好就退钱”美国公共医疗保障体系由联邦医疗保险计划（Medicare）与医疗补助计划（Medicaid）两大支柱构成。二者分别聚焦老年与低收入群体，共同构成基础保障网络。Medicare由联邦政府统一管理，覆盖65岁以上老年人及特定残障群体。Medicaid由联邦与州政府联合运作，侧重低收入人群（包括儿童、孕妇等弱势群体），各州可在联邦框架下自主制定具体覆盖范围与服务内容，资金由联邦和州政府按比例分担。长期以来，美国Medicaid以州为单位对部分药品开展价格谈判，以此控制支出。尽管2022年拜登政府出台的《通货膨胀削减法案》（Inflation Reduction Act, IRA）强制药企返利（如超出通胀的涨价）等措施对传统药品价格提供了一定约束，但公共医保项目医疗费用仍呈持续攀升势态，尤其在细胞与基因疗法（Cell & Gene Therapy, CGT）等昂贵创新疗法领域，支付挑战严峻。为了应对挑战，美国医疗保险和医疗补助服务中心（Centers for Medicare & Medicaid Services, CMS）于2024年12月4日正式启动了CGT医保支付创新试点。该试点打破传统支付模式，以联邦层面的集中谈判为基础，结合按疗效支付协议（Outcome-Based Agreement）与条件返利（rebate）机制，旨在为可从根本上治愈罕见病和严重遗传疾病的昂贵创新疗法建立可持续的支付解决方案。根据CMS规划，该试点初期将聚焦镰状细胞病（Sickle Cell Disease, SCD）的两种基因疗法——Vertex Pharmaceuticals开发的Casgevy与Bluebird Bio研发的Lyfgenia。此类疗法费用高达220万至310万美元，是史上最昂贵的精准治疗药物之一。然而根据美国疾病控制与预防中心（CDC）的数据显示，SCD患者人均寿命较美国平均水平短20余年，且其中约50%为Medicaid参保者。对于这一低收入及弱势群体而言，若无公共医保支持，患者将无法获得挽救生命的治疗方案。SCD若未得到有效治疗，会产生一系列并发症并造成患者反复住院，进一步加剧医疗负担。CMS希望通过此次试点解决昂贵创新疗法的可及性问题，确保低收入群体及时获得此类天价救命药。根据CMS网站发布的项目介绍书，此次试点的核心目标在于，从联邦层面进行价格谈判、统一市场准入标准并纳入按疗效付费，消除因各州政策差异导致的覆盖不均的问题，保障所有参与州的Medicaid患者可以公平获得基因治疗，最终达到人群健康水平上升的目的。具体而言，这一新支付模式的实施方式主要为三步：联邦层面（CMS）主导进行通过统一谈判与定价、设置分层返利机制等方式控制付费，最后各州可自主选择是否参与。统一谈判与定价：因SCD患者群体规模小但治疗成本极高，CMS选择先从SCD基因疗法试点。具体而言，CMS代表各州与药企进行集中谈判，达成全国统一价格和准入标准。为确保协议落地，CMS将提供技术支持，进行监督和疗效评估，核查各州执行时的合规性，并建立疗效追踪系统（电子健康档案）以评估返利触发条件。图1：CMS CGT准入模式实施时间表(来源：cms.gov)分层返利机制：为了进一步降低药品净成本，CMS在价格谈判中设计了具有借鉴意义的三重返利结构，包括量价挂钩、按疗效结果分期返利、固定价格让步等。药企需提供与采购量挂钩的基础折扣，并根据疗效达标率追加附加返利（如患者五年内复发或五年内人群疾病复发率≥n%，再返利x%）。因此只有患者达到特定疗效标准后，医保才需支付部分或全部药费；若疗效不达标，药企需退还部分费用或承担额外责任。此外，CMS的谈判要求药企提供与绩效无关的固定价格让步（如一次性降价x%），使得谈判结果对医保资金有即时保护效果。值得注意的是，此番价格谈判的结果并不推翻已有的折扣协议，而是将以附加协议的形式，在原有《通货膨胀削减法案》下的医疗补助计划药品返利方案（Medicaid Drug Rebate Program, MDRP）的降价协议上进一步降低价格，使得新药在原先折扣的基础上进一步享受新谈判带来的降价。图2：CMS CGT准入模式返利结构(来源：cms.gov)图3：CMS CGT准入模式返利时间点(来源：cms.gov)试点的实施方式上，州政府层面则体现为各州自愿参与机制，保留一定自主选择权。各州可以自主选择是否参与试点计划，若加入，州政府将直接采用CMS与药企谈判达成的统一价格及支付模式，不得另行议价或修改核心返利规则。CMS CGT创新支付模式试点是美国医保支付体系的一次重大变革。通过集中谈判，美国正在尝试降低昂贵创新药品的支付成本，提高Medicaid参保者的医疗可及性。CMS谈判中纳入按疗效支付的协议也真正将药企的收入与临床结果直接挂钩，既强化了企业对治疗有效性的责任，又减轻了医保资金负担。因此，美国业界认为，尽管本次试点仅涉及两款CGT，但从已公布的CMS文件中可以预计此次谈判对相关产品定价潜力的影响将超越《通货膨胀削减法案》带来的降价。SCD的患者病程较长、病情反复，所用医保资源较为可观。虽然纳入两款药物的前期费用很高，美国CMS认为CGT有望从根源治愈疾病，因此可以减少长期的医疗开支。如果试点成功，该模式可能会扩展至其他高成本的CGT，甚至影响全球医保支付模式的发展。对中国的启示：“最优性价比”或许是医保谈判的下一阶段目标美国CMS试点提出的“集中谈判+按疗效支付”模式为全球医保改革提供了新范例，也为中国医保支付模式的深化提供了可操作性的启示。中国国家医保谈判虽然已经展现出规模效应，但在按疗效支付等机制上仍有探索空间。具体而言，中国可借鉴CMS经验，推进支付模式向精细化方向改革，包括构建以“疗效”为核心的支付机制，在集中谈判基础上建立多层次的返利体系、建设独立疗效评估机制，以实现医保资金的精准支出和可持续运行。首先，最直接的借鉴就是如何保持量价挂钩与激励创新之间的平衡，“直接降价”模式未必是最佳选择。美国CMS CGT试点实践经验表明，分散化谈判模式存在显著弊端，各州政策割裂导致药品价格差异扩大、医保支出持续承压。相较之下，集中谈判通过规模化议价机制，在抑制价格攀升与促进医疗技术可及性方面拥有显著优势。CMS试点选择构建全国统一谈判框架，正是为了利用规模化采购优势实现成本结构优化，同时规避因分散决策而导致的管理低效与资源浪费问题。中国近年来的国家药品医保谈判同样在全球范围内引起关注。中美两国均通过国家层面主导的集中谈判提升买方议价能力，但具体实施路径存在差异。我国医保局使用以价格换取医保资格的策略使药企接受大幅降价来推动创新疗法的医保覆盖。无论实施路径如何，国家集中谈判在快速提升药品可及性的同时，也需要兼顾医保可负担性与激励创新之间的平衡。如果价格被过度压缩的同时，市场销量增幅有限，使企业销售收入难以覆盖前期的研发与生产成本，或使其利润率长期显著低于国际基准，可能抑制企业的研发动力，甚至出现制药企业参与药价谈判积极性降低的情况。中国医保谈判可在现有谈判框架上进一步优化现有支付模式。医保管理可以从单一的价格控制逐步转向综合的费用管理。与此同时，企业从不承担医保风险的角色，转向与医保部门共同承担风险。为此，未来可以探索引入多种风险共担机制（如按疗效支付、分期返利等），避免“一刀切”的支付政策。当今医疗技术快速发展，新药研发模式日益多样，因此新技术本身的复杂性也要求医保支付模式具备更高的适应性。美国CMS试点中的分层返利机制即为此提供了有益借鉴，通过将药企收益与患者临床疗效动态衔接，既确保医保资金的有效使用，又激励企业追求高质量创新，使具备真实临床价值的创新疗法获得可持续的发展空间。美国CMS试点的另一个可借鉴之处在于，如何向按疗效支付的改革迈步。我国现行基本医保支付模式目前主要采用单一价格谈判，按疗效支付模式尚未大规模应用。此次CMS试点的核心之一就是按疗效支付，精准使用医保资金，不为无效治疗买单。在按疗效支付协议的框架下，治疗方案需要达到双方约定患者获益的疗效指标，药企才能获得支付。因此按疗效支付可激起企业医疗质量方向上的创新动力，使企业更注重药品的临床效果和长期收益，而非仅关注上市后的销售。按疗效支付也将推动更多可提供高额临床获益的治疗方式被纳入医保体系，使得更多患者可以得到重焕新生的治疗。未来，中国可以考虑在罕见病、基因疗法等高价值技术领域引入按疗效支付的协议，形成精细化的医保支付体系。美国CMS试点的疗效挂钩协议为中国提供了可操作性极强的参考框架。从具体落地的角度上来看，按疗效支付模式的建立需要聚焦以下几个关键环节：一方面，具有分阶段支付与长期疗效观察能力的基础建设是执行按疗效支付模式重中之重的前提条件，也是其运行核心。中国可优先在罕见病、肿瘤免疫治疗（如CAR-T）等高值药品领域试行按疗效支付。例如，对某一CAR-T疗法可要求“完全缓解率”指标作为全额支付门槛，未达标则触发返利机制。另一方面，按疗效支付模式长期健康的运作需要一个完善的疗效评估体系。为保证评估结果的真实性，评估机构必须独立。第三方评估机构或相关部门应负责疗效数据追踪与验证，确保制药企业与医疗机构数据客观真实。此外，任何疗效评估体系都需要针对不同疾病制定量化、可追溯的疗效标准。以基因疗法为例，可设定“基因表达稳定性”“5年无进展生存率”等核心结果指标。需注意避免模糊定义，导致支付争议。同时，法律法规也有待完善，明确医保、药企、医院的责任边界，并建立纠纷仲裁机制。结论：昂贵药品，国家集中谈判+按疗效支付，是全球医保支付的趋势美国CMS试点模式的推出，标志着全球医保改革正在向高效、风险分担、可持续的方向迈进。这一创新支付试点揭示了两个核心理念：第一，在高价创新疗法支付领域，集中谈判机制能产生显著的规模效应，是提升买方议价能力、控制药品价格的有效手段，中国在创新药谈判中已证明其可行性，美国的CMS试点也在朝这一方向靠拢。第二，按疗效支付是未来医保改革的关键路径，它不仅能够确保资金的精准使用，更能加速推动优质药物进入市场。在全球医疗成本不断攀升、基因疗法和创新药物层出不穷的背景下，医保支付模式的创新已成为各国政府必须面对的挑战。美国CMS的新试点虽然刚刚开始，但其背后的逻辑正为全球医保体系验证一条可行的道路。对中国而言，需在现有医保谈判基础上，加快构建包含风险共担、数据驱动、全周期管理的创新支付体系，并开展实施方案试点，形成可复制的中国方案。参考资料：CMS.

蓝鸟生物收购遇波折：Ayrmid 出价 “流产”

近日，基因疗法公司蓝鸟生物（bluebird bio）的收购进程陷入了戏剧性的转折。原本看似有望获得更高报价的蓝鸟生物，因爱尔兰投资公司 Ayrmid 未能按预期提交有约束力的收购要约，不得不重新回归与凯雷集团（Carlyle）和 SK 资本伙伴（SK Capital Partners）的原始交易，这一事件在生物医药投资领域引发了广泛关注。Ayrmid “爽约”，蓝鸟生物收购计划生变蓝鸟生物在基因疗法领域一直备受瞩目，然而其市场表现却不尽人意。今年 2 月，蓝鸟生物与凯雷集团和 SK 资本伙伴达成收购协议，这两家投资公司将以每股 3 美元，总计 3000 万美元的价格收购蓝鸟生物，使其私有化，交易原计划于 2025 年上半年完成。3 月下旬，Ayrmid 突然杀出，主动提出以每股 4.5 美元的价格收购蓝鸟生物，较原始报价高出 50%，并且承诺根据销售里程碑再支付每股 6.84 美元。这一出价看似诱人，给蓝鸟生物的股东们带来了更多希望。双方随后展开了为期两周的尽职调查，期间蓝鸟生物还应 Ayrmid 的要求将调查期延长了 4 天。但令人意外的是，调查结束后，Ayrmid 不仅未能提交有约束力的收购要约，还承认自身缺乏完成收购所需的资金。蓝鸟生物困境凸显，原始交易成 “救命稻草”蓝鸟生物董事会主席马克・瓦雄（Mark Vachon）表示，公司已与 Ayrmid 进行了两次接触，但均未得到有约束力或资金充足的报价。他还指出，若不能获得某种形式的资金注入，蓝鸟生物将面临贷款违约的风险。在这种情况下，蓝鸟生物董事会重申对凯雷集团和 SK 资本伙伴原始交易的支持。蓝鸟生物曾经估值颇高，在 2018 年时峰值接近 125 亿美元。尽管该公司获得了美国食品药品监督管理局（FDA）对多种基因疗法的批准，如治疗镰状细胞病的 Lyfgenia、治疗 β - 地中海贫血的 Zynteglo 以及治疗脑肾上腺白质营养不良的 Skysona，但这些疗法在市场上的接受度较低，销售缓慢，导致公司财务状况逐渐恶化。到 2025 年第一季度，蓝鸟生物的资金即将耗尽，分析师们担忧其在今年难以实现收支平衡。因此，与凯雷集团和 SK 资本伙伴的交易，成为了蓝鸟生物的 “救命稻草”。行业影响与展望：投资需谨慎，企业求突破Ayrmid 的 “爽约” 给蓝鸟生物的发展带来了不确定性，也为生物医药投资领域敲响了警钟。对于企业来说，在寻求外部投资和并购机会时，需要更加谨慎地评估潜在合作伙伴的实力和诚意；而对于投资者而言，在做出投资决策前，更要全面考量目标公司的财务状况、市场前景以及潜在风险。蓝鸟生物未来的发展仍然充满挑战，即使顺利完成与凯雷集团和 SK 资本伙伴的交易，如何提升现有基因疗法的市场表现，开发更具竞争力的产品，依旧是摆在其面前的难题。此次事件也让行业更加关注基因疗法领域的投资环境和企业的可持续发展，未来，基因疗法企业在吸引投资和实现商业成功的道路上，需要不断探索新的模式和策略。参考来源：https://www.biospace.com/deals/bluebirds-second-suitor-ayrmid-fails-to-produce-an-offer识别微信二维码，添加抗体圈小编，符合条件者即可加入抗体圈微信群！请注明：姓名+研究方向！本公众号所有转载文章系出于传递更多信息之目的，且明确注明来源和作者，不希望被转载的媒体或个人可与我们联系(cbplib@163.com)，我们将立即进行删除处理。所有文章仅代表作者观点，不代表本站立场。

Bluebird bio reaffirms Carlyle deal as Ayrmid misses deadline

bluebird has been under financial pressure for several years. Credit: SOPA Images via Getty Images. Bluebird bio (bluebird) has reaffirmed its support for a proposed acquisition by Carlyle and SK Capital after rival bidder Ayrmid failed to deliver a binding offer or secure financing by the extended deadline. The announcement marks the second time Ayrmid has initiated discussions with bluebird without producing a fully financed proposal. Bluebird said it had engaged with Ayrmid for three weeks following the private equity firm’s unsolicited bid in March, including extending the original deadline to allow more time for due diligence and deal structuring. However, Ayrmid did not submit a definitive proposal by the agreed-upon 15 April cut-off date and has yet to secure the necessary capital to proceed. As a result, bluebird’s board of directors is reiterating its unanimous support for the acquisition agreement with Carlyle and SK Capital, which was first announced in February 2025. The board is urging shareholders to tender their shares by the updated deadline of 2 May, extending the previous expiration date of 18 April. bluebird’s board chairman Mark Vachon said: “Ayrmid’s proposal remains highly conditional. bluebird has engaged with Ayrmid on two separate occasions—neither of which has resulted in a binding or fully-financed offer. The board unanimously reaffirms its support of the previously announced agreement with Carlyle and SK Capital in the strongest possible terms.” Bluebird has been under significant financial pressure for several years. The company currently faces the risk of defaulting on a $175m loan from Hercules Capital, secured in 2024 to support ongoing operations. Without a new capital injection, the board said, the company’s liquidity position remains precarious. Carlyle and SK Capital’s proposal offers $3 per share in cash, along with a potential additional payment of $6.84 per share if certain clinical and commercial milestones are met. Ayrmid‘s offer, disclosed last month, proposed $4.50 per share upfront and the same milestone-based payout structure. However, bluebird confirmed that Ayrmid has not demonstrated access to committed funding. bluebird noted that Ayrmid is continuing to seek financing and may provide further updates in the coming days. bluebird’s financial position has deteriorated over time, despite achieving several key regulatory milestones. The company currently markets three US Food and Drug Administration (FDA)- approved gene therapies – Zynteglo (betibeglogene autotemcel) for transfusion-dependent beta-thalassemia, Skysona (elivaldogene autotemcel) for cerebral adrenoleukodystrophy, and Lyfgenia (lovotibeglogene autotemcel) for sickle cell disease – but has struggled with slow uptake, high costs, and reimbursement hurdles. In 2023, the company suffered a major setback when the FDA denied a priority review voucher (PRV) for Lyfgenia. Bluebird had already arranged to sell the voucher to Novartis for $103m, but the agency ruled that the therapy’s active ingredient had previously been used in Zynteglo, for which the company had already received a PRV in 2022. The loss of the expected funds deepened bluebird’s financial strain. To fill the gap, bluebird pursued emergency financing through a $150m public stock offering underwritten by Goldman Sachs and JP Morgan, as well as up to $100m in receivables financing from Alterna Capital Solutions. The company has also undergone repeated cost-cutting efforts, including workforce reductions of 30% in 2022 and an additional 25% last year. Despite these efforts, bluebird’s therapies continue to face stiff competition. Lyfgenia is priced at $3.1m per patient, while a competing treatment, Casgevy (exagamglogene autotemcel) from Vertex Pharmaceuticals and CRISPR Therapeutics, is listed at $2.2m. Both therapies were approved on the same day in December 2023 to treat sickle cell disease. Going public in 2013, bluebird has seen its stock decline sharply in recent years.

This guide addresses how cell thawing has historically developed into the new techniques used today, along with the physical and biological implications of key metrics and components such as warming rate and ice structure. Also included are reviews of key studies from scientific literature and a consideration of the interactions between cooling and warming rates, as applicable to cell and gene therapies. Thank you.
