BACKGROUND:

There are no approved oral disease-modifying treatments for Alzheimer's disease (AD).

OBJECTIVES:

The objective of this study was to assess efficacy and safety of blarcamesine (ANAVEX®2-73), an orally available small-molecule activator of the sigma-1 receptor (SIGMAR1) in early AD through restoration of cellular homeostasis including autophagy enhancement.

DESIGN:

ANAVEX2-73-AD-004 was a randomized, double-blind, placebo-controlled, 48-week Phase IIb/III trial.

SETTING:

Multicenter - 52 medical research centers/hospitals in 5 countries.

INTERVENTION:

508 participants with early AD (Stage 3) were randomized to receive either blarcamesine (n = 338) in medium dose group 30 mg or in high dose group 50 mg or placebo (n = 170) oral capsules once daily for 48 weeks. Participants in these groups were offered to enroll into the open-label-extension study ATTENTION-AD, which completed June 2024, ClinicalTrials.gov Identifier NCT04314934.

MEASUREMENTS:

The co-primary cognitive and functional outcomes were assessed as change in ADAS-Cog13 and ADCS-ADL from baseline to 48 weeks. The outcomes include the secondary outcome CDR-SB and biomarkers from the A/T/N spectrum, plasma Aβ42/40-ratio and global brain volume changes measured by MRI. All clinical endpoints were analyzed using mixed model for repeated measures (MMRM), plasma biomarker measurements were analyzed by Welch's t-test, and volumetric MRI scans were analyzed by general linear model.

RESULTS:

Among 462 randomized participants in the intent-to-treat population (mean age, 73.7 years; 225 [48.7%] women), 338 (73.2%) completed the trial. The co-primary outcome was met under the multiplicity control rule, since the differences in the least-squares mean (LSM) change from baseline to 48 weeks between the prespecified blarcamesine and placebo groups for ADAS-Cog13 was significant at a level of P < 0.025 and for CDR-SB was significant at a level of P < 0.025, while ADCS-ADL did not reach significance at Week 48 (ADAS-Cog13 difference of -2.027 [95% CI -3.522 to -0.533]; P = 0.008; CDR-SB difference of -0.483 [95% CI -0.853 to -0.114]; P = 0.010; ADCS-ADL difference of 0.775 [95%CI -0.874 to 2.423]; P = 0.357). Plasma Aβ42/40-ratio increased significantly with blarcamesine group vs. placebo, (P = 0.048) and whole brain volume loss was significantly decreased (P = 0.002). Participants in the full safety population with ≥1 serious treatment-emergent adverse events (TEAEs) occurred in 56 participants (16.7%) in the blarcamesine and 17 (10.1%) in the placebo group. Common TEAEs included dizziness, which was transient and mostly mild to moderate in severity. One death in the blarcamesine group and 1 in the placebo group were both not considered treatment related.

CONCLUSIONS:

Blarcamesine, demonstrating a safety profile with no associated neuroimaging adverse events, significantly slowed clinical progression by 36.3% at 48 weeks with blarcamesine group as well as the individual 30 mg (by 34.6%) and 50 mg (by 38.5%) blarcamesine groups vs. placebo on the prespecified primary cognitive endpoint ADAS-Cog13. The prespecified secondary endpoint CDR-SB, which is used as the sole primary endpoint in recent successful AD drug submissions, is significantly improved at Week 48 with blarcamesine relative to placebo. The findings are supported by biomarkers from the A/T/N spectrum, including plasma Aβ42/40-ratio and reduction of whole brain atrophy. Additionally, the prespecified SIGMAR1 gene variant subgroup analysis confirmed beneficial clinical effect of blarcamesine group through upstream SIGMAR1 activation - subjects with the common SIGMAR1 wild-type gene (excluding carriers of the mutated SIGMAR1 rs1800866 variant) experienced an even greater significant clinical benefit with slowed clinical progression by 49.8% at 48 weeks on the prespecified primary cognitive endpoint ADAS-Cog13. Oral once daily blarcamesine could represent a novel treatment in early AD and be complementary or alternative to anti-beta amyloid drugs.

Rett Syndrome: The Emerging Landscape of Treatment Strategies

Review

作者: Neul, Jeffrey L. ; Percy, Alan K ; Percy, Alan K. ; Neul, Jeffrey L ; Ananth, Amitha

Rett syndrome (RTT) has enjoyed remarkable progress in achieving specific therapies. RTT, a unique neurodevelopmental disorder first described in 1966, progressed slowly until the landmark paper of Hagberg and colleagues in 1983. Thereafter, rapid advances were achieved including the development of specific diagnostic criteria and the active search for a genetic etiology, resulting 16 years later in identification of variants in the methyl-CpG-binding protein (MECP2) gene located at Xq28. Shortly thereafter, the NIH Office of Rare Diseases funded the RTT Natural History Study (NHS) in 2003, initiating the acquisition of natural history data on clinical features from a large population of individuals with RTT. This information was essential for advancement of clinical trials to provide specific therapies for this disorder. In the process, the International Rett Syndrome Association (IRSA) was formed (now the International Rett Syndrome Foundation-IRSF), which participated directly in encouraging and expanding enrollment in the NHS and, subsequently, in developing the SCOUT program to facilitate testing of potential therapeutic agents in a mouse model of RTT. The overall objective was to review clinical characteristics developed from the NHS and to discuss the status of specific therapies for this progressive neurodevelopmental disorder. The NHS study provided critical information on RTT: growth, anthropometrics, longevity, key comorbidities including epilepsy, breath abnormalities, gastroesophageal dysfunction, scoliosis and other orthopedic issues, puberty, behavior and anxiety, and progressive motor deterioration including the appearance of parkinsonian features. Phenotype-genotype correlations were noted including the role of X chromosome inactivation. Development of clinical severity and quality of life measures also proved critical for subsequent clinical trials. Further, development of biochemical and neurophysiologic biomarkers offered further endpoints for clinical trials. Initial clinical trials prior to the NHS were ineffective, but advances resulting from the NHS and other studies worldwide promoted significant interest from pharmaceutical firms resulting in several clinical trials. While some of these have been unrewarding such as sarizotan, others have been quite promising including the approval of trofinetide by the FDA in 2023 as the first agent available for specific treatment of RTT. Blarcamesine has been trialed in phase 3 trials, 14 agents have been studied in phase 2 trials, and 7 agents are being evaluated in preclinical/translational studies. A landmark study in 2007 by Guy et al. demonstrated that activation of a normal MECP2 gene in a null mouse model resulted in significant improvement. Gene replacement therapy has advanced through translational studies to two current phase 1/2 clinical trials (Taysha102 and Neurogene-401). Additional genetic therapies are also under study including gene editing, RNA editing, and X-chromosome reactivation. Taken together, progress in understanding and treating RTT over the past 40 years has been remarkable. This suggests that further advances can be expected.

Central role of Sigma-1 receptor in ochratoxin A-induced ferroptosis

Article

作者: Liu, Shuangchao ; Chen, Wenying ; Han, Lingyun ; Zhou, Yao ; Deng, Huiqiong ; Wang, Hongwei ; Yang, Ruiran ; Shen, Xiao Li ; Yao, Song

Ochratoxin A (OTA), a secondary fungal metabolite known for its nephrotoxic effects, is prevalent in various feeds and food items. Our recent study suggests that OTA-induced nephrotoxicity is linked to the Sigma-1 receptor (Sig-1R)-mediated mitochondrial pathway apoptosis in human proximal tubule epithelial-originated kidney-2 (HK-2) cells. However, the contribution of Sig-1R to OTA-induced nephrotoxicity involving other forms of regulated cell death, such as ferroptosis, remains unexplored. In this investigation, cell viability, malondialdehyde (MDA) levels, glutathione (GSH) levels, and protein expressions in HK-2 cells treated with OTA and/or Ferrostatin-1/blarcamesine hydrochloride/BD1063 dihydrochloride were assessed. The results indicate that a 24 h-treatment with 1 μM OTA significantly induces ferroptosis by inhibiting Sig-1R, subsequently promoting nuclear receptor coactivator 4 (NCOA4), long-chain fatty acid-CoA ligase 4 (ACSL4), arachidonate 5-lipoxygenase (ALOX5), autophagy protein 5 (ATG5), and ATG7, inhibiting ferritin heavy chain (FTH1), solute carrier family 7 member 11 (SLC7A11/xCT), glutathione peroxidase 4 (GPX4), peroxiredoxin 6 (PRDX6), and ferroptosis suppressor protein 1 (FSP1), reducing GSH levels, and increasing MDA levels (P < 0.05). In conclusion, OTA induces ferroptosis by inhibiting Sig-1R, subsequently promoting ferritinophagy, inhibiting GPX4/FSP1 antioxidant systems, reducing GSH levels, and ultimately increasing lipid peroxidation levels in vitro.

Anavex Life Sciences Announces Issuance of Blarcamesine (ANAVEX®2-73) Composition of Matter U.S. Patent Expanding its Intellectual Property Portfolio

Jan. 27, 2025 -- Anavex Life Sciences Corp. (“Anavex” or the “Company”) (Nasdaq: AVXL), a clinical-stage biopharmaceutical company focused on developing innovative treatments for Alzheimer's disease, Parkinson's disease, schizophrenia, neurodevelopmental, neurodegenerative, and rare diseases, including Rett syndrome, and other central nervous system (CNS) disorders, announced today it was issued a new U.S. Patent No. 12,180,174 entitled “A2-73 CRYSTALLINE POLYMORPH COMPOSITIONS OF MATTER AND METHODS OF USE THEREOF” from the United States Patent and Trademark Office (USPTO) for its U.S. Patent Application Serial Number USSN: 17/978,818. This new patent claims crystalline forms of the dihydrogen phosphate salt of ANAVEX®2-73 (blarcamesine), freebase, transdermal patches and enteric coated oral dosage forms including the same for neuroprotection and treatment of neurodegenerative disorders, including Alzheimer’s disease, Parkinson’s disease and other disorders. Anavex’s newest patent will be expected to remain in force at least until July 2039, not including any patent term extensions. It will expand and supplement the current ANAVEX®2-73 (blarcamesine) patent portfolio, which includes several U.S. Patents, including U.S. Patent Nos. 10,413,519; 10,966,952; 11,661,405; and 11,498,908. “The issuance of this U.S. Patent again showcases our expertise in identifying and pursuing novel therapeutic forms and formulations that are rooted in science,” said Christopher U. Missling, PhD, President and Chief Executive Officer of Anavex. He further added: “We believe the unique properties of the dihydrogen phosphate crystals make it possible in addition to convenient once daily oral dosing to also deliver the active (ANAVEX®2-73 freebase) in transdermal patches, which could simplify further the administration and boost patients’ compliance. As such, we believe that the addition of the dihydrogen phosphate crystals to our platform could greatly benefit the patients at large.” Crystal polymorphism is a unique phenomenon related to chiral compounds, wherein the compounds may crystallize into different crystal structures or crystal forms under different conditions and/or processes. Specifically for pharmaceuticals, polymorphic forms of drug substances ‘exist in different crystalline forms which differ in their physical properties’.1 These property differences may result in direct medical implications, such as ease of formulation, increased efficacy, and reduced side effects. For example, the widely used analgesic drug, acetaminophen has three polymorphic forms, I, II, and III, among which only Form I is made into commercial dosage forms as the other two forms are either meta-stable or unstable.2 Nonetheless, uncovering an optimal crystal form is NOT an easy or straightforward task, because there are so many variables and possibilities involved, and chance of success lies heavily on the researcher’s experience and insights into the compounds in question. Both ANAVEX®2-73 (blarcamesine) and ANAVEX®19-144 have the potential to form different crystal forms. Through its deep understanding and abundance experience with these two compounds, Anavex was successful in discovering crystal forms of ANAVEX®2-73 (blarcamesine) and ANAVEX®19-144 that have advantageous physiochemical and/or pharmacological properties.

Anavex Life Sciences Announces Peer-Reviewed Publication of Oral Blarcamesine Phase IIb/III Data in The Journal of Prevention of Alzheimer’s Disease

Blarcamesine potential novel oral treatment to target upstream Alzheimer’s disease pathology through autophagy enhancement Impairment of autophagy precedes both amyloid beta and tau tangles, and therefore anticipates the neurodegenerative process in Alzheimer’s disease Jan. 15, 2025 -- Anavex Life Sciences Corp. (“Anavex” or the “Company”) (Nasdaq: AVXL), a clinical-stage biopharmaceutical company focused on developing innovative treatments for Alzheimer's disease, Parkinson's disease, schizophrenia, neurodevelopmental, neurodegenerative, and rare diseases, including Rett syndrome, and other central nervous system (CNS) disorders, today announced that The Journal of Prevention of Alzheimer’s Disease (JPAD) has published peer-reviewed detailed results from the Phase IIb/III study evaluating oral blarcamesine (ANAVEX®2-73) for the treatment of early Alzheimer’s Disease (AD). Once daily oral blarcamesine, demonstrating a safety profile with no associated neuroimaging adverse events, significantly slowed clinical progression by 36.3% at 48 weeks with blarcamesine group as well as the prespecified SIGMAR1 wild-type gene group by 49.8% at 48 weeks on the prespecified primary cognitive endpoint ADAS-Cog13. Oral once daily blarcamesine could represent a novel treatment in early Alzheimer’s disease and be complementary or alternative to injectable anti-beta amyloid drugs. “The Alzheimer’s disease community has been actively pursuing new medicines for decades. To have data like these published in JPAD gives us energy and hope. We are now seeing in the data what we suspected about blarcamesine for a long time – that it has the potential to make a clinical difference for people living with early Alzheimer’s disease,” said senior author behavioral neurologist Professor Dr. Marwan Noel Sabbagh MD, Chairman of the Scientific Advisory Board. “The advantage of blarcamesine lies in its small oral formulation, which offers clinical benefits for cognition and neurodegeneration. Its ease of administration and favorable safety profile make it an appealing option.” Data from the Phase IIb/III trial demonstrated oral once daily blarcamesine pre-specified clinical efficacy through upstream SIGMAR1 activation. SIGMAR1 is an integral membrane protein which activates an upstream compensatory process: Blarcamesine induces autophagy through SIGMAR1 activation resulting in restoring cellular homeostasis. “The results from the Phase IIb/III blarcamesine study show real promise for patients living with early Alzheimer’s disease,” said lead author Associate Professor Dr. Stephen Macfarlane, FRANZCP, Head of Clinical Services at the Dementia Centre, HammondCare and Principal Investigator. “Early Alzheimer’s disease can progress swiftly, and the potential for blarcamesine to target on a constitutional level of the pathology should bring hope and excitement to persons living with Alzheimer’s disease and those of us who care for them.” Impaired autophagy precedes both amyloid beta and tau tangles, and therefore anticipates the neurodegenerative process in Alzheimer’s disease.1 Hence, stabilization or restoration of autophagy can be seen as an early preventative measure countering the Alzheimer’s disease pathology. “Publication of the pivotal placebo-controlled Phase IIb/III blarcamesine early Alzheimer’s disease trial allows for a broader dissemination of these important data and highlights blarcamesine’s impressive and consistent clinical profile that has led to meaningful results for these patients,” said Juan Carlos Lopez-Talavera, MD, PhD, Head of Research and Development of Anavex. “These data serve as the foundation for the MAA filing that is currently being reviewed by the EMA. We are aiming to potentially advance an important medicine to patients in need.” Blarcamesine, a small molecule administered orally once daily, demonstrated clinically meaningful improvement over 48 weeks with primary endpoint ADAS-Cog13 score being larger than 2 points.2 This suggests superior numerical clinical efficacy compared to approved therapies while also slowing neurodegeneration in early Alzheimer’s disease patients. Blarcamesine’s safety profile indicates not requiring routine MRI monitoring, and given its differentiated mechanism of action, oral blarcamesine could represent a novel treatment that could be complementary or an alternative to injectable anti-beta amyloid monoclonal antibody drugs. “The peer-reviewed publication of these data underscores the significance of the findings for both the scientific community and those focused on Alzheimer's disease,” said Christopher U. Missling, PhD, President and Chief Executive Officer of Anavex. “Alzheimer's disease is a highly complex condition, and this dataset plays a crucial role in advancing our understanding of the Phase IIb/III results. We are grateful to the dedication from participants, their families, and the sites for taking part in this important study.” This release discusses investigational uses of an agent in development and is not intended to convey conclusions about efficacy or safety. There is no guarantee that any investigational uses of such product will successfully complete clinical development or gain health authority approval. The publication may be accessed here. There are an estimated 7 million people in Europe with Alzheimer’s disease, a number expected to double by 2030, according to the European Brain Council.3 The World Health Organization (WHO) estimated the cost in Europe of caring for people with dementia, including Alzheimer's disease, at $439 billion, or $31,144 per person in 2019.

Anavex's lead drug candidate, ANAVEX®2-73 (blarcamesine), has successfully completed a Phase 2a and a Phase 2b/3 clinical trial for Alzheimer's disease, a Phase 2 proof-of-concept study in Parkinson's disease dementia, and both a Phase 2 and a Phase 3 study in adult patients and one Phase 2/3 study in pediatric patients with Rett syndrome. ANAVEX®2-73 is an orally available drug candidate designed to restore cellular homeostasis by targeting SIGMAR1 and muscarinic receptors. Preclinical studies demonstrated its potential to halt and/or reverse the course of Alzheimer's disease. ANAVEX®2-73 also exhibited anticonvulsant, anti-amnesic, neuroprotective, and anti-depressant properties in animal models, indicating its potential to treat additional CNS disorders, including epilepsy. The Michael J. Fox Foundation for Parkinson's Research previously awarded Anavex a research grant, which fully funded a preclinical study to develop ANAVEX®2-73 for the treatment of Parkinson's disease. We believe that ANAVEX®3-71, which targets SIGMAR1 and M1 muscarinic receptors, is a promising clinical stage drug candidate demonstrating disease-modifying activity against the major hallmarks of Alzheimer's disease in transgenic (3xTg-AD) mice, including cognitive deficits, amyloid, and tau pathologies. In preclinical trials, ANAVEX®3-71 has shown beneficial effects on mitochondrial dysfunction and neuroinflammation.
