[0003] field
[0004] This invention relates to the medical field, and in particular to a method for treating endometriosis.
[0005] background
[0006] Endometriosis is a chronic inflammatory gynecological disease characterized by the presence of ectopic endometrial glands and stroma, primarily located in the pelvic peritoneum, ovaries, and rectovaginal septum. It is estimated that approximately 5-15% of women of reproductive age worldwide have endometriosis (PMID: 27159755), while the prevalence can reach 35-80% in women experiencing pelvic pain and / or infertility (PMID: 32212520, 33640070). Due to the variable symptoms and the ease with which endometriosis symptoms can be confused with those of other diseases, diagnosis is often delayed, with an average delay of 4 to 12 years (PMID: 8671344, 22990516, 12790847, 28440744). The etiology of endometriosis is unclear, and several hypotheses have been proposed to explain the origin of this disease (PMID: 30026507 review). From a pathological perspective, genetic factors, environmental factors, immune dysfunction, and estrogen imbalances can all contribute to the formation and maintenance of endometriosis lesions (PMID:30026507). Among these, steroid production disorder is the most studied mechanism in the pathology of endometriosis, which can manifest as abnormal changes in hormone levels, and abnormal hormone levels are a common risk factor for this disease.
[0007] Due to the complexity and diversity of its pathogenesis, endometriosis remains incurable. Various treatment methods have been employed to address both endometriosis and infertility, including surgery, medication, and acupuncture. Hormone therapy is considered the first-line treatment for endometriosis. In multiple Phase III clinical trials, two approved hormonal drugs, Elagolix and Myfembree, demonstrated their effectiveness in relieving pain caused by endometriosis without any safety issues (PMID: 28525302, 29889764, 34134684, 33066973, 35717987).
[0008] Although endometriosis is not fatal, chronic pain and infertility can significantly impact quality of life. It is estimated that the economic burden of endometriosis in the United States alone reaches $80 billion annually (PMID: 35620300). Nevertheless, mounting evidence suggests that endometriosis is a systemic disease that alters cardiovascular, neurological, metabolic, and immune function (PMID: 33640070). Patients may have an increased risk of developing a variety of chronic diseases, such as adenomyosis (PMID: 24532217), ovarian cancer (PMID: 28240000), and autoimmune diseases (PMID: 31260048). These factors collectively underscore the need for innovative and effective treatments for this disease. To address this, we utilized the AI-driven target discovery platform PandaOmics to identify S1PR1 as a repurposed candidate for treating endometriosis.

[0044] Active agent used to treat endometriosis
[0045] Through extensive research, the inventors have discovered a target for the treatment of endometriosis: sphingosine-1-phosphate receptor 1 (S1PR1). Antagonists or agonists of this target can be used to treat endometriosis.
[0046] Sphingosine-1-phosphate receptor 1 (S1P receptor 1 or S1PR1), also known as endothelial differentiation gene 1 (EDG1), is a protein encoded by the S1PR1 gene in humans. S1PR1 is a G protein-coupled receptor that binds to the biologically active signaling molecule sphingosine-1-phosphate (S1P). S1PR1 belongs to a five-member (S1PR1-5) subfamily of sphingosine-1-phosphate receptors. S1PR1 was initially identified as an abundant transcript in endothelial cells and plays a crucial role in regulating endothelial cytoskeleton structure, migration, capillary-like network formation, and angiogenesis. Furthermore, S1PR1 signaling is essential in the regulation of lymphocyte maturation, migration, and transport.
[0047] The active agent used to treat endometriosis can be any one of the S1PR1 antagonists, including but not limited to bonesimod, ozanimod, cibonimod, fingolimod, eltromod, sinimod, mokramod dihydrochloride, amiserol hydrochloride, CBP-307, TT-01688-CL, vibocilimod, icoplanin, SCD-044, BMS-986166, BMS-986104, CP-1050, BMS-520, BMS-542, cirafimod, PF-04629991 and their derivatives.
[0048] The structure of an exemplary S1PR1 antagonist is shown below.

[0074] 1. Method
[0075] Data sources and availability
[0076] The current analysis utilized batch and single-cell transcriptomics and proteomics data. A total of 36 endometriosis-related batch transcriptomics datasets from various tissue sources, retrieved from GeneExpression Omnibus (GEO) and ArrayExpress, including microarrays and RNA sequencing series, were available for direct downstream analysis and target identification using PandaOmics. Two single-cell transcriptomics datasets, GSE179640 and GSE203191, were also extracted from GEO.
[0077] Datasets and Comparison Selection
[0078] Since the pathogenesis of the disease begins with the situ endometrium, endometrial tissue datasets were selected for downstream analysis and target identification. Eleven case-control comparisons were generated from the eleven batch transcriptomics datasets listed in Table 1. Normal endometrial tissue from healthy individuals and situ endometrial tissue from patients with endometriosis were selected as controls, labeled "healthy" and "situ endometrium" respectively in the experimental design column of Table 1.
[0079] Table 1. Meta-analysis comparison of endometriosis for target selection
[0080]
[0081] PandaOmics target identification
[0082] PandaOmics is a cloud-based target discovery platform that combines multiple deep learning models and AI algorithms in the target prioritization process. Twenty-three target prioritization models have been developed, covering omics (Omics), text-based, financial, and key opinion leader (KOL) data, to predict the association between target genes and specific indications. Each model is scored on a normalized scale from zero to one, with higher scores corresponding to better predicted target-disease associations. These models are validated using time-machine methods to demonstrate their capabilities in target identification. The target list can also be refined using adjustable filters based on drugability, tissue specificity, target family, and development status.
[0083] To identify potential targets for endometriosis, a case-control batch transcriptomics comparison was assigned to a meta-analysis. To identify actionable targets with varying levels of novelty, filter and scoring settings were customized to re-prioritize targets. Only targets belonging to druggable protein classes were retained in the analysis, excluding those considered essential genes as defined by the Therapeutic Target Database (TTD). Therefore, three lists of druggable targets were generated: high confidence, moderate novelty, and high novelty, with the top 50 targets undergoing further analysis.
[0084] Single-cell transcriptomics data processing and analysis
[0085] For GSE203191, menstrual flow samples were collected from 11 individuals with diagnosed endometriosis, 13 symptomatic individuals (undiagnosed but with symptoms of chronic endometriosis), and 9 control individuals. Samples in GSE179640 were collected from five regions: healthy endometrium, situ endometrium from patients with endometriosis, ectopic endometriotic tissue from the ovaries and peritoneum, and tissue near endometriotic lesions in the peritoneum.
[0086] For GSE203191, the sample data matrix generated by Cell Ranger was retrieved from the GEO database, and gene and cell filtering and cell cluster annotation were performed according to the definitions in the original literature (PMID: 36104692). For GSE179640, the authors readily provided processed data including calibrated expressions, cell cluster annotations, sample metadata, and dimensionality-reduced coordinates, and extracted them from [the original literature]. https: / / singlecell.jax.org / datasets / endometriosis-2022Search. Differential gene expression between different cell clusters or sample groups was calculated using log-normalized count data and the Wilcoxon rank sum test.
[0087] Pathway analysis
[0088] Signaling pathway activation status was assessed using Ipanda (PMID: 27848968), a proprietary single-network model from PandaOmics. By combining differential gene expression data with pathway topological decomposition, iPANDA robustly identified multiple sets of biologically relevant pathway features from the input data and significantly reduced noise. iPANDA values of 1 and -1 represent pathway activation and inhibition, respectively. The hierarchical structure of signaling pathways was curated based on the Reactome database.

[0090] Identifying S1PR1 as a potential therapeutic target using PandaOmics
[0091] Based on expression correlation results, target identification was performed using a meta-analysis of endometriosis with non-specific comparisons of 11 subtypes and cycles (Table 1). To identify potential therapeutic targets for endometriosis, high-confidence targets associated with the disease were screened based on rankings calculated by PandaOmics, consistency of dysregulated expression in comparisons included in the meta-analysis, statistical significance of the dysregulation, and literature support indicating potential roles in driving or promoting endometriosis. S1PR1 was ranked 223rd in the meta-analysis and scored at least 0.8 in four omics AI scoring models (i.e., network neighbor, expression, heterogeneous graph walk, and matrix factorization). Figure 1A ).
[0092] Upregulation of S1PR1 was observed in endometriosis transcriptomic datasets.
[0093] To investigate the functional association between S1PR1 and endometriosis, the expression profiles of S1PR1 were analyzed between samples collected from endometriotic lesions and control endometrium. Regarding batch transcriptomic characteristics, S1PR1 was upregulated in 10 out of 11 comparisons (90.9%), with 6 of these upregulations reaching statistical significance (FDR < 0.05) (Table 2). Two single-cell transcriptomic datasets for endometriosis, GSE179640 and GSE203191, were also extracted to investigate cell-specific expression profiles.

[0095]
[0096] GSE179640 consisted of control samples collected from endometrium, virgin endometrium from patients, ectopic endometriosis lesions from the peritoneum and ovaries, and tissue adjacent to endometriosis lesions in the peritoneum. In GSE179640, S1PR1 was specifically enriched in endothelial cells. It was significantly overexpressed in endothelial cells of ovarian endometriosis samples and in one of its myeloid cell clusters. Furthermore, upregulated expression of this gene was also detected in NK cells and a myeloid cell cluster of peritoneal endometriosis lesions and adjacent tissues. Figure 1B and 1C On the other hand, three sets of samples were available in GSE203191—menstrual discharge collected from individuals with endometriosis (diagnosed), symptomatic, and control. No significant LFC of S1PR1 was observed in case-control comparisons of any cell type.
[0097] S1PR1 agonists as candidates for reuse in endometriosis
[0098] Using PandaOmics' proprietary single-network model iPANDA, S1PR1 primarily facilitates immune regulatory pathways, through which most of these pathways are significantly activated in endometriosis samples. Figure 1D Literature has demonstrated the crucial role of S1PR1 and its ligand sphingosine-1-phosphate (S1P) in the immune response. Association information between S1PR1 variants and traits was retrieved from the GWAS catalog, and half of the traits were immune-related. Loss of S1PR1 function is lethal in mice. Conditional mutations in S1PR1 drive severe phenotypic abnormalities in the immune, cardiovascular, and neuronal systems (PMID: 22975327, 16314531, 12869509, 20584883, 21960637). S1PR1 has been reported to be upregulated in endometriosis (PMID: 30782093, 22277765). S1P increases IL-6 expression and the proliferative capacity of endometriotic cells (PMID: 30782093). Inhibition of S1PR1 and S1PR3 suppressed S1P-induced proliferation of endometriotic stromal cells (PMID: 30782093). S1P and its downstream pathways mediate the induction of COX-2 and PGE2 production, both important mediators of inflammation (PMID: 12890694, 26994820). Since endometriosis is a chronic inflammatory disease, and S1PR1 is closely associated with endometriosis, targeting S1PR1 could be a potential treatment for endometriosis.
[0099] Marketed S1PR1 agonists such as fingolimod, ciponimod, ozanimod, and bonesimod functionally antagonize the action of S1PR1 and are indicated for the treatment of multiple sclerosis. The binding of these compounds to S1PR1 induces receptor internalization and degradation. In particular, bonesimod specifically acts on the S1PR1 receptor. In addition to the marketed compounds, 16 other compounds have been engineered to target S1PR1 and tested on various endpoints, namely eltromod, ciponimod, mokramod dihydrochloride, amiserol hydrochloride, CBP-307, TT-01688-CL, vibocilimod, icoplanin, SCD-044, BMS-986166, BMS-986104, CP1050, BMS520, BMS542, cirafimod, and PF-04629991.
