With more than 2,000 research studies published so far, the progressive supranuclear palsy domain has garnered significant attention from researchers, but there is no cure for terminal illness, so far. As per our research, nearly 15 clinical-stage progressive supranuclear palsy investigational programs <em>(highlighted below)<\/em>, have been discontinued, in the last two decades. In 2019, owing to the failure to meet the desired endpoints, two big pharma players, <a href=\"https:\/\/www.alzforum.org\/news\/research-news\/abbvies-tau-antibody-flops-progressive-supranuclear-palsy\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Abbvie<\/a> and <a href=\"https:\/\/investors.biogen.com\/news-releases\/news-release-details\/biogen-reports-top-line-results-phase-2-study-progressive\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Biogen<\/a> announced their decision to terminate the development of their pipeline anti-tau antibodies for progressive supranuclear palsy, namely ABBV-8E12 and gosuranemab, respectively.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"502\" height=\"110\" src=\"https:\/\/www.rootsanalysis.com\/blog\/wp-content\/uploads\/2023\/10\/PSP-therapy-development-terminated-Dormant-Program-Roots-Analysis.webp\" alt=\"15 clinical-stage PSP investigational programs, have been discontinued, in the last two decades - Roots Analysis\" class=\"wp-image-19073\" style=\"object-fit:contain;width:800px;height:175px\" srcset=\"https:\/\/www.rootsanalysis.com\/blog\/wp-content\/uploads\/2023\/10\/PSP-therapy-development-terminated-Dormant-Program-Roots-Analysis.webp 502w, https:\/\/www.rootsanalysis.com\/blog\/wp-content\/uploads\/2023\/10\/PSP-therapy-development-terminated-Dormant-Program-Roots-Analysis-300x66.webp 300w\" sizes=\"auto, (max-width: 502px) 100vw, 502px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Since majority of the trials evaluating potential Progressive Supranuclear Palsy therapeutics candidates were discontinued because of endpoint failure, in-depth research is needed to identify the endpoints that should be measured in these trials. Owing to the high failure rates of progressive supranuclear palsy to prove efficacy, and the consequent delay in commercialization of a curative therapy, physicians have no option, but to prescribe less effective generic medications, such as antiparkinsonian and anti-depressants, along with non-pharmacological therapies. \u00a0Driven by the non-availability of a disease modifying therapy, higher number of hospitalizations, outpatient visits, and prescriptions, mean total cost per progressive supranuclear palsy patient amounts to more than <a href=\"https:\/\/www.valueinhealthjournal.com\/article\/S1098-3015(19)31837-6\/pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">USD 35,000<\/a>, annually. As a result, the healthcare industry is faced with a pressing need for accurate diagnostic (predictive) tests, and efficient treatment options that have the capability to cure or slow the progression of this neurodegenerative disease. Sponsor companies should follow best practices for disseminating the experience and data resulting from terminated trials in order to facilitate maximum benefit from the investments of trial participants and others who are involved in the clinical trial study.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Nearly 25 investigational therapeutic compounds are currently being evaluated by close to 20 industry and non-industry players<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">According to our study, the market is still in its infancy with only 20% of the therapies being evaluated in phase II studies, the most advanced stage of development. Owing to their ability to cross the blood-brain barrier, small molecule drugs represent ~70% of the progressive supranuclear palsy pipeline; this is followed by anti-tau antibodies and antisense oligonucleotide molecules. While majority of the PSP therapy developers are small <em>(with less than 50 employees), <\/em>this niche market has witnessed the engagement of few large players, including Eisai and Novartis, that are leading the development of phase I clinical programs.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"619\" height=\"267\" src=\"https:\/\/www.rootsanalysis.com\/blog\/wp-content\/uploads\/2023\/10\/List-of-PSP-Drugs-Development-Roots-Analysis.webp\" alt=\"More than 100 clinical trials, related to Progressive Supranuclear Palsy, were registered in the last two decades - Roots Analysis\" class=\"wp-image-19074\" style=\"object-fit:contain;width:800px;height:400px\" srcset=\"https:\/\/www.rootsanalysis.com\/blog\/wp-content\/uploads\/2023\/10\/List-of-PSP-Drugs-Development-Roots-Analysis.webp 619w, https:\/\/www.rootsanalysis.com\/blog\/wp-content\/uploads\/2023\/10\/List-of-PSP-Drugs-Development-Roots-Analysis-300x129.webp 300w\" sizes=\"auto, (max-width: 619px) 100vw, 619px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>More than 100 clinical trials, related to progressive supranuclear palsy, have been registered in the last two decades<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Stakeholders are actively investigating therapeutic interventions (molecules \/ devices) and diagnostics for this rare and complex disorder; nearly 50% of these studies are in phase I trials.
