2022年11月30日，礼来公布其药物donanemab达III期试验达6个月所有主要终点和次要终点，为早期症状性阿尔茨海默病患者的淀粉样蛋白斑块清除提供了首个Aduhelm头对头比较数据。该III期试验（TRAILBLAZER-ALZ 4）在阿尔茨海默病临床试验（CTAD）会议上公布。主要终点为大脑淀粉样斑块清除（大脑淀粉样斑块水平<24.1 Centiloids）。donanemab组6个月时这一比例为37.9%，Aduhelm组仅1.6%。在一个关键的次要终点中，donanemab组在6个月时脑部淀粉样蛋白水平与基线相比降低了65.2%，Aduhelm组为17.0%。安全性方面，ARIA是两组中最常见的治疗突发不良事件。Aduhelm组总的ARIA发生率为26.1%，其中4.3%为症状性的；在donanemab组，总的ARIA发生率为25.4%，其中2.8%有症状。布朗大学阿尔茨海默病研究中心副主任Stephen表示：令人鼓舞的是，donanemab在6个月后明显减少了大脑中淀粉样蛋白的积累和血液中的P-tau，值得注意的是，与Aduhelm相比，donanemab在6个月时更高的淀粉样蛋白清除率与较高的ARIA率无关。Donanemab是靶向N3pG（β淀粉样斑块的一种修饰形式）的研究性抗体药物，据悉，Donanemab加速批准的PDUFA日期为2023年2月，加速审批是基于早期的II期试验，将加速批准转变为完全批准的验证性试验也将在2023年中期读出数据。目前TRAILBLAZER-ALZ 4还将进行12个月和18个月的二级分析，该研究也是评估donanemab疗效和安全性临床项目的五项研究之一。值得一提的是，在过去的20年里，被称为“天坑”的AD领域有百余款新药均研发失败，临床失败率高达97.3%，辉瑞、礼来、罗氏等制药巨头也曾几度折戟。已上市的Aduhelm，由于其临床疗效数据问题而几经挫折，经历了上市申请撤回、限制使用、销售业绩惨淡、销售团队解散等一系列问题。Biogen 2022年一季度财报中，销售额280万美元，不及预期。同时，Biogen/卫材的另一款Aβ药物Lecanemab三期临床达主要终点，近期也因安全问题争议不断，lecanemab加速批准的PDUFA日期为2023年1月6日。扫码查询现货细胞系往期推荐泛癌种靶点Trop2，国内各家竞相角逐PROTAC全球布局一览国产PD-1销售盘点点击下方“药研网”，关注更多精彩内容

DUBLIN--( BUSINESS WIRE )--The "AAV vectors in gene therapy - Pipeline Insight, 2022" drug pipelines has been added to ResearchAndMarkets.com's offering. AAV vectors in gene therapy: Overview Out of the several viral vectors that have been used to date for delivering the genes of interest, the Adeno-associated viral (AAV) vector appears to be the safest and effective vehicle and can maintain long-term gene and protein expression following a single injection of the vector. AAV vectors are the leading viral vectors for gene delivery to treat a variety of human diseases. Recent advances in developing clinically desirable AAV capsids, optimizing genome designs, and harnessing revolutionary biotechnologies have contributed extensively to the growth of the gene therapy field. AAV Vectors in Gene Therapy Emerging Drugs GS010: Gensight Biologics LUMEVOQ (GS010; lenadogene nolparvovec) targets Leber Hereditary Optic Neuropathy (LHON) by leveraging a mitochondrial targeting sequence (MTS) proprietary technology platform, arising from research conducted at the Institut de la Vision in Paris, which, when associated with the gene of interest, allows the platform to specifically address defects inside the mitochondria using an AAV vector (Adeno-Associated Virus). The gene of interest is transferred into the cell to be expressed and produces the functional protein, which will then be shuttled to the mitochondria through specific nucleotidic sequences in order to restore the missing or deficient mitochondrial function. "LUMEVOQ" was accepted as the invented name for GS010 (lenadogene nolparvovec) by the European Medicines Agency (EMA) in October 2018. Valoctocogene roxaparvovec: BioMarin Pharmaceutical Valoctocogene roxaparvovec is an investigational AAV5 gene therapy under regulatory review for the treatment of severe hemophilia A. It is currently in preregistration stage of development. In June 2021, BioMarin resubmitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA). In the United States, BioMarin intends to submit two-year follow-up safety and efficacy data on all study participants from the Phase III GENEr8-1 study to support the benefit/risk assessment of valoctocogene roxaparvovec, as previously requested by the Food and Drug Administration (FDA). BioMarin is targeting a Biologics License Application (BLA) resubmission in the second quarter of 2022, assuming favorable study results, followed by an expected six-month review by the FDA. DTX401: Ultragenyx Pharmaceutical DTX401 is an investigational AAV8 gene therapy designed to deliver stable expression and activity of G6Pase-? under control of the native promoter. DTX401 is administered as a single intravenous infusion and has been shown in preclinical studies to improve G6Pase-? activity and reduce hepatic glycogen levels, a well-described biomarker of disease progression. In a Phase I/II clinical study, all nine patients showed a clinical response, with significant reductions in the need for cornstarch and improvements in glucose control and other metabolic parameters compared to baseline. The drug is currently being evaluated in Phase III clinical trial to treat patients with Glycogen storage disease type I. AAV5-RPGR: MeiraGTx AAV-RPGR is an investigational gene therapy for the treatment of patients with X-linked retinitis pigmentosa (XLRP) caused by disease-causing variants in the eye specific form of the RPGR gene (RPGR ORF15). AAV-RPGR is designed to deliver functional copies of the RPGR gene to the subretinal space in order to improve and preserve visual function. MeiraGTx and development partner Janssen are currently conducting a Phase III clinical trial of AAV-RPGR in patients with XLRP with disease-causing variants in RPGR ORF15. Timrepigene emparvovec: Biogen Timrepigene emparvovec is an AAV2 vector administered by subretinal injection, which aims to provide a functioning CHM gene and expression of the REP-1 protein to restore membrane trafficking and thereby slow, stop or potentially reverse decline in vision. Data from the Phase 1/2 studies demonstrated a slower rate of decline in visual acuity in patients treated with timrepigene emparvovec compared to untreated patients in the natural history study. In addition, some patients treated with timrepigene emparvovec showed improvements in visual acuity. The studies also demonstrated that timrepigene emparvovec was generally well tolerated with an acceptable safety profile. The safety and efficacy of a single subretinal injection of timrepigene emparvovec is currently being evaluated in the ongoing Phase III STAR study. AMT 061: UniQure AMT-061 (etranacogene dezaparvovec) is an experimental gene therapy that uniQure is developing to treat hemophilia B. AMT-061 uses a modified and harmless adeno-associated virus 5 (AAV5) to deliver a highly functional copy of the F9 gene, called FIX-Padua, to patients' cells. The FIX-Padua gene version was shown to result in FIX clotting activity eight times greater than that associated with the standard F9 gene. As such, the one-time therapy - administrated directly into the bloodstream - is expected to increase FIX levels, helping to prevent and control bleeds. If approved, the therapy will be marketed globally by CSL Behring, which closed a commercialization and licensing agreement with uniQure in May 2021. UniQure and CSL Behring expect to file a regulatory application to the U.S. Food and Drug Administration (FDA) in early 2022 seeking AMT-061's approval for hemophilia B. Research and Development. RGX-314: REGENXBIO RGX-314 is being investigated as a potential one-time treatment for wet AMD, diabetic retinopathy, and other chronic retinal conditions. RGX-314 consists of the NAV AAV8 vector, which encodes an antibody fragment designed to inhibit vascular endothelial growth factor (VEGF). RGX-314 is believed to inhibit the VEGF pathway by which new, leaky blood vessels grow and contribute to the accumulation of fluid in the retina. REGENXBIO is advancing research in two separate routes of administration of RGX-314 to the eye, through a standardized subretinal delivery procedure as well as delivery to the suprachoroidal space. REGENXBIO has licensed certain exclusive rights to the SCS Microinjector from Clearside Biomedical, Inc. to deliver gene therapy treatments to the suprachoroidal space of the eye. According to the company's pipeline, the drug is currently in the Phase III stage of development. SPK-8011: Spark Therapeutics Investigational SPK-8011, a novel bio-engineered adeno-associated viral (AAV) vector utilizing the AAV-LK03 capsid, also referred to as Spark200, contains a codon-optimized human factor VIII gene under the control of a liver-specific promoter. The Food and Drug Administration (FDA) granted orphan-disease designation and breakthrough therapy designation in the US, while the European Commission has granted orphan designation to SPK-8011. NFS-01: Neurophth Investigational NR082, a novel recombinant adeno-associated viral serotype 2 vector (rAAV2) containing a codon-optimized of NADH-dehydrogenase subunit 4 (ND4) gene under the control of the cytomegalovirus promoter and enhancer, is a novel ophthalmic injection that is being developed for the treatment of Leber hereditary optic neuropathy (LHON) associated with ND4 mutations. It is currently being evaluated in Phase II/III clinical trial. GT 005: Gyroscope Therapeutics GT005 is designed as an AAV2-based one-time investigational gene therapy for GA secondary to AMD that is delivered under the retina. GT005 aims to restore balance to an overactive complement system, a part of the immune system, by increasing production of the CFI protein. Complement overactivation has been strongly correlated with the development and progression of AMD. The CFI protein regulates the activity of the complement system. It is believed that increasing CFI production could dampen the system's overactivity and reduce inflammation, with the goal of preserving a person's eyesight. Gyroscope is also evaluating GT005 in two Phase II clinical trials.
