AI Technical Summary
Current treatments for asthma and COPD lack predictive methods to determine which patients will respond to specific antibody therapies, making it difficult to personalize treatment approaches effectively.
A method involving the calculation of an IL-33 asthma polygenic risk score (IL-33 asthma PRS) to stratify patients, using a weighted sum of genetic variants near or within the IL-33 and IL1RL1 genes, to guide the administration of IL-33 antagonists, interleukin-4 receptor alpha antagonists, or interleukin-13 receptor antagonists based on individual genetic risk profiles.
The IL-33 asthma PRS allows for personalized treatment strategies by predicting patient response to IL-33 antagonists, improving treatment efficacy and reducing asthma exacerbations and loss of asthma control.

[0002] Field The present invention relates to the field of therapeutic treatment of pulmonary diseases. More specifically, the present disclosure relates to methods of increasing the efficacy of interleukin-33 (IL-33) antagonist, interleukin-4 receptor alpha antagonist, and / or interleukin-13 receptor antagonist therapy in subjects with pulmonary diseases by identifying subjects likely to respond to an IL-33 antagonist, an interleukin-4 receptor alpha antagonist, and / or an interleukin-13 receptor antagonist. [Background technology]
[0003] Asthma is an inflammatory disease of the airways of the lungs. The condition is characterized by a variety of recurrent symptoms, reversible airflow obstruction, and easily provoked bronchospasm. Diagnosis of asthma may include pulmonary function testing with spirometry, including assessment of forced expiratory volume in 1 second (FEV1), peak expiratory flow, and annual exacerbation rate. Treatment of asthma involves the administration of immediate or long-term effective medications. Salbutamol and albuterol are the mainstay of immediate-acting medications, while inhaled corticosteroids (ICS) have been the cornerstone of long-term treatment for many years. Recently, antibodies such as mepolizumab, dupilumab, and omalizumab have been used in connection with certain types of asthma. However, it is difficult to predict whether a particular subject will respond to a particular antibody therapy. It is also difficult to predict prospectively the annual exacerbation rate or loss of asthma control (LOAC).
[0004] Chronic obstructive pulmonary disease (COPD) is characterized, in part, by symptoms of airflow limitation, emphysema, and chronic bronchitis. COPD is often exacerbated by daily activities, which makes daily tasks difficult. Tobacco smoke is the main risk factor, but other factors include pollution, genetics, and exposure to dust and chemicals in the workplace. Diagnosis of COPD often involves spirometry, including measuring the patient's FEV1 value. Current treatments include smoking cessation, short-acting bronchodilators, phosphodiesterase 4 inhibitors, corticosteroids, and, in severe cases, antibiotics. However, it is difficult to predict whether a patient will respond to a particular treatment. Summary of the Invention

[0011] Genetic factors play an important role in the risk of developing disease and can potentially affect how an individual responds to drug treatment. A polygenic risk score (PRS) combines information from multiple genetic variants obtained from disease association studies to create a single composite quantitative measure for each individual that reflects the genetic risk of disease. Individuals with a higher number of risk alleles for a particular disease will have a higher PRS than individuals with a lower number of alleles for the same particular disease. Risk can be assessed at some threshold, for example, percentiles, standard deviation units of population distribution, or absolute values. The present disclosure generally relates to the unexpected finding that stratification of subjects by IL-33 asthma PRS is useful for identifying subjects likely to respond to IL-33 antagonists, interleukin-4 receptor alpha antagonists, and / or interleukin-13 receptor antagonists in the treatment of lung diseases, such as asthma and COPD.

[0016] The present disclosure generally relates to methods and compositions for treating subjects suffering from or at risk of developing a pulmonary disease, such as asthma and COPD. In some embodiments, the pulmonary disease comprises asthma. In some embodiments, the pulmonary disease comprises COPD.
[0017] Without being limited to a particular theory, it is believed that the IL-33 asthma PRS calculated according to the methods presented herein allows for the identification of subjects likely to respond to an IL-33 antagonist, an interleukin-4 receptor alpha antagonist, and / or an interleukin-13 receptor antagonist. Moreover, surprisingly and unexpectedly, the IL-33 asthma PRS is also predictive of a subject's response to an IL-33 antagonist, an interleukin-4 receptor alpha antagonist, and / or an interleukin-13 receptor antagonist.
[0018] In some embodiments, subjects treatable by the methods of the present disclosure have had asthma within the past 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, or 18 months.

Subjects treatable by the methods of the present invention include subjects who have been hospitalized for COPD-related symptoms, as well as subjects who are currently hospitalized.
[0020] In some embodiments, subjects may be selected based on an IL-33 asthma PRS, where the IL-33 asthma PRS comprises the sum or weighted sum of multiple genetic variants associated with asthma or COPD and is calculated using at least about 2, at least about 3, at least about 4, at least about 5, at least about 10, at least about 20, at least about 30, at least about 40, at least about 50, at least about 60, at least about 70, at least about 80, at least about 100, at least about 120, at least about 150, at least about 200, at least about 250, at least about 300, at least about 400, at least about 500, at least about 1,000, at least about 2,000, at least about 3,000, at least about 4,000, at least about 5,000, at least about 6,000, at least about 7,000, at least about 8,000, at least about 9,000, or at least about 10,000 genetic variants. If the subject has an IL-33 asthma PRS that is equal to or greater than the threshold IL-33 asthma PRS, the subject should be administered an IL-33 antagonist. Alternatively, if the subject has an IL-33 asthma PRS that is less than the threshold IL-33 asthma PRS, the subject should be administered an interleukin-4 receptor alpha antagonist and / or an interleukin-13 receptor antagonist. In some embodiments, the sum of the multiple genetic variants associated with asthma is a weighted sum of the multiple genetic variants associated with asthma. In some embodiments, the genetic variant is selected from any one or more of the variants listed in Table 1 (Variant D according to the GRCh38 / hg38 human genome assembly coordinates).

[0038] [Table 2]
[0039] Risk assessment using multiple genetic variants provides the advantage of improved predictive power. In some embodiments, one or more of the genetic variants are single nucleotide polymorphisms (SNPs). In some embodiments, one or more of the genetic variants are insertions. In some embodiments, one or more of the genetic variants are deletions. In some embodiments, one or more of the genetic variants are structural variants.

[0040] In some embodiments, the disclosure provides a method of determining an IL-33 asthma PRS in a subject, the method comprising: detecting at least about 2 genetic variants, at least about 5 genetic variants, at least about 10 genetic variants, at least about 15 genetic variants, at least about 20 genetic variants, at least about 30 genetic variants, at least about 40 genetic variants, at least about 50 genetic variants, at least about 60 genetic variants, at least about 70 genetic variants, at least about 100 genetic variants, at least about 200 genetic variants, at least about 300 genetic variants, at least about 40 ...50 genetic variants, at least about 60 genetic variants, at least about 70 genetic variants, at least about 100 genetic variants, at least about 200 genetic variants, at least about 300 genetic variants, at least about 400 genetic variants, at least about 50 genetic variants, at least about 50 genetic variants, at least about 60 genetic variants, at least The method includes determining whether at least about 1,000 genetic variants, at least about 2,000 genetic variants, at least about 3,000 genetic variants, at least about 4,000 genetic variants, at least about 5,000 genetic variants, at least about 6,000 genetic variants, at least about 7,000 genetic variants, at least about 8,000 genetic variants, at least about 9,000 genetic variants, or at least about 10,000 genetic variants are present in the subject's biological sample. The presence of the risk allele increases the subject's IL-33 asthma PRS.
[0041] In some embodiments, the disclosure provides a method of determining an IL-33 asthma PRS in a subject, the method comprising identifying whether one or more genetic variants associated with risk of developing asthma are present in a biological sample from a subject, and calculating an IL-33 asthma PRS for the subject based on the identified genetic variants (wherein the IL-33 asthma PRS is calculated, for example, by summing, e.g., aggregating, the risk scores (or weighted risk scores) associated with each identified genetic variant). The number of identified genetic variants may be at least about 2 genetic variants, at least about 5 genetic variants, at least about 10 genetic variants, at least about 15 genetic variants, at least about 20 genetic variants, at least about 30 genetic variants, at least about 40 genetic variants, at least about 50 genetic variants, at least about 95 genetic variants, at least about 100 genetic variants, at least about 200 genetic variants, at least about 3 ... At least about 500 genetic variants, at least about 1,000 genetic variants, at least about 2,000 genetic variants, at least about 3,000 genetic variants, at least about 4,000 genetic variants, at least about 5,000 genetic variants, at least about 6,000 genetic variants, at least about 7,000 genetic variants, at least about 8,000 genetic variants, at least about 9,000 genetic variants, or at least about 10,000 genetic variants.In some embodiments, the disclosure provides a method of determining an IL-33 asthma PRS in a subject comprising identifying whether genetic variants associated with risk of developing asthma are present in a biological sample from the subject, wherein the identification process identifies at least about 2 genetic variants, at least about 5 genetic variants, at least about 10 genetic variants, at least about 15 genetic variants, at least about 20 genetic variants, at least about 30 genetic variants, at least about 40 genetic variants, at least about 50 genetic variants, at least about 95 genetic variants, at least about 100 genetic variants, at least about 15 ... At least about 100 genetic variants, at least about 200 genetic variants, at least about 500 genetic variants, at least about 1,000 genetic variants, at least about 2,000 genetic variants, at least about 3,000 genetic variants, at least about 4,000 genetic variants, at least about 5,000 genetic variants, at least about 6,000 genetic variants, at least about 7,000 genetic variants, at least about 8,000 genetic variants, at least about 9,000 genetic variants, or at least about 10,000 genetic variants.
[0042] As an exemplary method, the IL-33 asthma PRS can be determined, for example, from data obtained from a GWAS of disease risk. For example, in a representative hypothetical GWAS, the GWAS may identify four genetic variants associated with the disease. Each genetic variant may be associated with one or more genes. Values such as odds ratios can be calculated for each individual genetic variant. The IL-33 asthma PRS of a particular subject can be determined by multiplying the log value of the individual odds ratios of each variant by the number effect allele (the number of copies of the genetic variant in the genome, i.e., 0, 1, or 2), and then summing the resulting values. This type of determination can be described in Table 3.
[0043] [Table 3]
[0044] Therefore, the IL-33 asthma PRS of a subject is the sum of the individual values in the last column of the table, taking into account any number of genetic variants associated with a particular disease.This simplified methodology for determining the IL-33 asthma PRS of a subject is for illustrative purposes only and is not to be construed as limiting in any way.The IL-33 asthma PRS of the above table is a weighted score, since each genetic variant may carry out different weighting depending on the specific odds ratio and number effect allele value.
[0045] In some embodiments, the disclosure provides a method of assigning an asthma risk group to a subject, the method comprising: determining whether a genetic variant is present in a biological sample from a subject; calculating an IL-33 asthma PRS for the subject based on the identified genetic variant; and assigning the subject to a risk group based on the IL-33 asthma PRS. A threshold PRS can be determined for each tier. In some embodiments, the tiers can be expressed in percentiles. As a non-limiting example, the IL-33 asthma PRS can be divided into quintiles, e.g., top quintile, upper middle quintile, middle quintile, lower middle quintile, and bottom quintile, with the top quintile of IL-33 asthma PRS corresponding to the highest genetic risk group and the bottom quintile of IL-33 asthma PRS corresponding to the lowest genetic risk group. The number of genetic variants identified can be at least about 2 genetic variants, at least about 5 genetic variants, at least about 10 genetic variants, at least about 15 genetic variants, at least about 20 genetic variants, at least about 30 genetic variants, at least about 40 genetic variants, at least about 50 genetic variants, at least about 95 genetic variants, at least about 100 genetic variants, at least about 200 genetic variants, at least about 500 genetic variants, at least about 1,000 genetic variants, at least about 2,000 genetic variants, at least about 3,000 genetic variants, at least about 4,000 genetic variants, at least about 5,000 genetic variants, at least about 6,000 genetic variants, at least about 7,000 genetic variants, at least about 8,000 genetic variants, at least about 9,000 genetic variants, or at least about 10,000 genetic variants associated with asthma.

[0054] In some embodiments, the identified genetic variants include genetic variants with the highest genetic variant performance in a reference population. In some embodiments, the genetic variant performance is calculated with respect to asthma risk based on statistical significance, strength of association, and / or probability distribution.
[0055] In some embodiments, the genetic variant score is calculated using any PRS calculation method. In some embodiments, the genetic variant score is calculated using a PRS calculation method such as the LDpred method (or its variants and / or versions). LDpred is a Bayesian approach that calculates the posterior average effect for all variants based on a prior (effect size in a prior genome-wide association study) and subsequent shrinkage based on linkage disequilibrium. LDpred creates a PRS using genome-wide polymorphisms with weights obtained from a set of summary statistics of genome-wide association studies (GWAS). See Vilhjalmsson et al., Am. J. Hum. Genet., 2015, 97, 576-92. In some embodiments, alternative approaches to calculate gene variant scores may be used, including SBayesR (Lloyd-Jones, LR, World Wide Web at biorxiv.org / content / biorxiv / early / 2019 / 01 / 17 / 522961.full.pdf), Pruning and Thresholding (P&T) (Purcell, Nature, 2009, 460, 748-752), and Conditional Joint Analysis (COJO) (Yang et al., Nat. Genet., 2012, 44, 369-375). SBayesR is a Bayesian approach similar to LDpred, but can be more flexible in posterior mean effects. Pruning and thresholding (P&T) is based on a minimum p-value threshold (the p-value associated with the variant in the source data file) and the r 2 A threshold (a measure of linkage disequilibrium (LD)) must be specified. P&T identifies the variant with the smallest p-value in each region and then calculates the p-value for the specified r 2 Greater than r 2All other variants in the region with a value are "lumped" under that variant. In a PRS, the index variant represents all variants in the clump (only the index variant is included in the PRS, all others are excluded). COJO is conceptually similar to P&T, but after conditioning on the index variant, it incorporates additional variants in a particular LD block into the score if they are shown to contribute independently to disease risk.
[0056] In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.0001 to about 0.5. In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.5. In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.1. In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.05. In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.01. In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.005. In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.001. In some embodiments, the genetic variant performance is calculated using the LDpred method and has a p value of about 0.0005.

[0076] In some embodiments, the method further includes initiating a treatment for the subject, which may include ICS, leukotriene modifiers, long-acting muscarinic antagonists (LAMA), long-acting beta agonists (LABA), theophylline, combination inhalers containing both a corticosteroid and a LABA, e.g., albuterol, short-acting beta agonists such as albuterol, ipratropium, oral corticosteroids (OCS), intravenous corticosteroids, allergy injections, allergy medications, omalizumab, mepolizumab, benralizumab, reslizumab, dupilumab, and itepekimab, or any combination thereof.
[0077] Examples of therapeutic agents useful in the treatment of asthma include, but are not limited to, ICS, leukotriene modifiers, long-acting beta agonists (LABAs), theophylline, combination inhalers containing both corticosteroids and LABAs, short-acting beta agonists such as albuterol, ipratropium, oral corticosteroids, intravenous corticosteroids, allergy injections, allergy medications, omalizumab, mepolizumab, benralizumab, reslizumab, dupilumab, and itepekimab, or any combination thereof. Standard amounts of these agents are determined by a physician according to label guidelines.
[0078] Initiating treatment may include devising a treatment plan based on the risk group corresponding to the calculated IL-33 asthma PRS for the subject. In some embodiments, the IL-33 asthma PRS predicts the effectiveness of treatment or the subject's response to a therapeutic regimen. Thus, treatment can be determined or adjusted depending on the IL-33 asthma PRS.
[0079] In some embodiments, initiating treatment involves modifying a dosage or regimen of a treatment already being received by a subject with asthma or COPD based on the calculated IL-33 asthma PRS for the subject. In some embodiments, initiating treatment involves replacing one therapeutic agent with another based on the IL-33 asthma PRS. In some embodiments, initiating treatment involves starting a regimen of a therapeutic agent in addition to a therapeutic agent already being received by the subject. In some embodiments, initiating treatment involves starting administration of a therapeutic regimen to a previously untreated asthma or COPD subject.
[0080] In some embodiments, the therapeutic agent is an IL-33 antagonist, an interleukin-4 receptor alpha antagonist, and / or an interleukin-13 receptor antagonist. In some embodiments, the IL-33 asthma PRS is predictive of the efficacy of treatment or a subject's response to treatment with an IL-33 antagonist, an interleukin-4 receptor alpha antagonist, and / or an interleukin-13 receptor antagonist. Thus, depending on the calculated IL-33 asthma PRS for a subject, IL-33 antagonist, interleukin-4 receptor alpha antagonist, and / or interleukin-13 receptor antagonist treatment can be determined or adjusted.
[0081] As used herein, the term "antagonist" means that a given compound is capable of inhibiting the activity of a respective protein or other substance in a cell, at least to a certain extent. This can be achieved by the direct interaction of the compound with a given protein or substance ("direct inhibition"), or by the interaction of the compound with other proteins or other substances inside or outside the cell, which leads to at least partial inhibition of the activity of the protein or substance ("indirect inhibition"). Inhibition of protein activity can also be achieved by suppressing the expression of the target protein. Techniques for inhibiting protein expression include, but are not limited to, antisense inhibition, siRNA-mediated inhibition, miRNA-mediated inhibition, ribozyme-mediated inhibition, DNA-directed RNA interference (DdRNAi), RNA-directed DNA methylation, transcription activator-like effector nuclease (TALEN)-mediated inhibition, zinc finger nuclease-mediated inhibition, aptamer-mediated inhibition, and CRISPR-mediated inhibition.

[0102] Example 1: Generation of a polygenic risk score Dataset: A pathway-specific asthma PRS was generated for a European population. The PRS consisted of 543 variants near or within the IL-33 and IL1RL1 genes. The LDpred method was used to estimate the contribution of individual SNPs from the asthma GWAS. Additionally, a pathway-specific asthma PRS was generated for an admixed American population. It included 205 variants near or within the IL-33 and IL1RL1 genes. The LDpred method was used to estimate the contribution of individual SNPs from the asthma GWAS.
[0103] PRS Algorithm Selection: We used the LDpred approach to generate polygenic risk scores. LDpred is a Bayesian approach to PRS development that calculates the posterior mean effect (adjusted effect size) of all variants based on prior and LD information from a reference panel. Heuristically, effect sizes generated from LDpred differ from P&T in that LDpred jointly models the effect size and variance of each marker and incorporates LD structure when shrinking effect sizes. The adjustment or shrinkage of variant weights is based not only on the magnitude of the association of the variant with the disease but also on the linkage disequilibrium (LD) between the variants. In the LDpred approach, data from 1000 Genomes phase 3 version 5 was used for the LD reference panel.
[0104] PRS calculation: From the LDpred approach, we generated a set of variants and their respective weights. For LDpred, the variant weights were the adjusted log odds ratios (posterior means). After generating the weights, the process of calculating and normalizing the scores was the same. For a set of M variants, j=1...,i=1...N patients, the PRS for patient j was calculated as follows:
[0105]
number
[0106] (In the formula, B iis the log odds ratio for variant i, and x ij where is the number of risk alleles carried in patient j at variant i (for imputed variants, the allele dosage of variant i). Scores were standardized to approximately N(0,1) by subtracting the mean PRS and dividing by the PRS standard deviation within each ancestral group.
[0107] PRS algorithm testing and validation: For each set of LDpred tuning parameters, the PRS was calculated and logistic regression was performed with the composite endpoint as the dependent variable and PRS, age, sex, and ancestry covariates as independent variables. For each model, odds ratios (OR) and areas under the curve (AUC) per PRS standard deviation (SD) were reported.
[0108] Choosing a threshold to define high risk: High genetic risk was defined as patients within the 25th, 50th, 75th, and 100th percentiles of the distribution of polygenic risk scores. This threshold was selected in a post-hoc analysis, which evaluated high genetic risk thresholds in the 25th, 50th, 75th, and 100th percentile ranges.
[0109] Statistical analysis: Baseline disease and medical history characteristics were analyzed to assess the distribution of asthma risk factors by genetic risk status (high (above percentile threshold) vs low (below percentile threshold)). Continuous baseline characteristics were compared using t-tests, and binary or categorical characteristics were tested using chi-square or Fisher's exact tests.
[0110] result: IL-33 asthma PRS determined using the LDpred method is significantly associated with higher annualized exacerbation rates in dupilumab-treated European patients. Both graphs in Figure 1 show the association between IL-33 asthma PRS and annualized exacerbation rates. In particular, panel A shows the genetic influence in patients undergoing the same treatment. The X-axis is the IL33 PRS score divided into quartiles and ranked from lowest to highest, and the Y-axis is the annualized exacerbation rate. In the dupilumab-treated group, those with higher IL33 PRS had higher exacerbation rates. The p-value is 0.41. This is also significant when comparing those in the top quartile with those in the remaining or lowest quartile, suggesting that those in the highest quartile of IL33 PRS are not benefiting as much as those in the lowest quartile of IL33 PRS. In particular, panel B shows a comparison of treatment effects according to quartile of IL33 PRS. In the quartiles of IL33 PRS, dupilumab-treated patients had significantly lower exacerbation rates. No differences were seen between the dupilumab and placebo groups in the highest quartile of IL33 PRS.
[0111] IL-33 Asthma PRS determined using LDpred was not associated with change in pre-bronchodilator FEV1 at week 12 in dupilumab-treated European patients, but patients with lower IL-33 Asthma PRS scores showed the greatest clinical benefit when compared to placebo-treated patients. In the study disclosed herein, other primary endpoints were change in FEV1 change (Figure 2). In particular, panel A shows that when comparing treatment effects, dupilumab treatment significantly increased FEV1 values in patients with lower IL33 PRS quartiles, but not in those with higher PRS quartiles.
[0112] IL-33 asthma PRS, determined using the LDpred method, tended to be associated with higher annualized exacerbation rates in dupilumab-treated mixed race American patients. Figure 3 shows that subjects in the higher quartiles of IL33 PRS (75 and 100 groups) were significantly associated with less effective response to dupilumab when comparing dupilumab-treated and placebo groups.
[0113] IL-33 Asthma PRS measured using the LDpred method was not associated with change in FEV1 at week 12 in dupilumab-treated mixed race American patients, but patients with lower IL-33 Asthma PRS scores had the greatest clinical benefit when compared to placebo-treated patients. Figure 4 shows the distribution of variants by sample. In the graph in Panel A, IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, and the numbers in each bar are the change in FEV1 at week 12. In the graph in Panel B, IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, and the numbers at the bottom of each bar indicate the number of patients in each group and the change in FEV1 at week 12.
[0114] The IL-33 Asthma PRS determined using the LDpred method showed a trend towards a reduced risk of LOAC in itepekimab monotreated European subjects. In 148 European samples, the IL33 Asthma PRS for European patients was applied (Figure 5). The IL-33 Asthma PRS was divided into quartiles and ranked from lowest to highest, the number at the bottom of each bar is the number of subjects in each group, and the number on each bar is the percentage of subjects with LOAC. It was found that the IL-33 Asthma PRS tended to be associated with reduced LOAC (p-value=0.055). When comparing the lowest quartile with the other quartiles, it was observed that patients with higher IL-33 Asthma PRS values had less LOAC compared to the lowest quartile. The variation of the IL-33 Asthma PRS by treatment regimen was not significant. However, this may be due to the small number of samples in this study. Figure 5 shows the trend in the itepekimab monotherapy group. Patients with higher IL33PRS scores showed fewer LOAC events.
[0115] IL-33 asthma PRS showed a trend towards a decreased risk of LOAC in European and mixed race American subjects treated with itepekimab monotherapy. The IL-33 asthma PRS of the remaining 50 mixed race American samples in the itepekimab trial was applied and combined with that of the European subjects (Figure 6). The IL-33 asthma PRS was divided into quartiles and ranked from lowest to highest, the number at the bottom of each bar is the number of subjects in each group, and the number on each bar is the percentage of subjects with LOAC. Also, asthma patients with higher IL-33-asthma PRS had less LOAC than patients in the lowest quartile of the itepekimab monotherapy group. The findings suggested that asthma patients with higher IL-33 asthma PRS may benefit more from itepekimab treatment. In the placebo group, IL-33 asthma PRS tended to be associated with increased LOAC. This suggested that placebo asthma patients with a high IL33 asthma PRS suffered more LOAC. Figure 6 shows that in the itepekimab monotherapy group, asthma patients with a high IL33 PRS had less LOAC than those in the lowest quartile. This suggests that asthma patients with a high IL33-based genetic risk may benefit more from itepekimab treatment. In the placebo group, IL33 PRS tended to be associated with increased LOAC, suggesting that asthma patients in the higher quartiles of IL33 PRS suffered more LOAC.
[0116] The IL-33 asthma PRS determined using the LDpred method was significantly associated with asthma in GHS_GSA European subjects. The GHS_GSA population is a cohort of the Geisinger Health System. The IL-33 asthma PRS was strongly associated with asthma risk (p-value = 4.18 × 10 -30) (FIG. 7). In the graph in Panel A, the IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, the numbers below each bar are the number of subjects in each group, and the numbers in each bar are the percentage of asthma subjects. In the graph in Panel B, the IL-33 Asthma PRS percentiles and the vertical axis are the odds ratios of the percentage of asthma subjects. FIG. 7 shows the validated IL33 Asthma PRS correlated with asthma risk. The IL33 Asthma PRS determined by LDpred was significantly associated with asthma in GUS-GSA European subjects.
[0117] The IL-33 asthma PRS determined using the LDpred method was significantly associated with eosinophil count in GHS_GSA European subjects. The IL-33 asthma PRS measured using the LDpred method also showed a significant association with eosinophil count (p-value = 1.73 × 10 -40 ) (FIG. 8). In the graph in panel A, the numbers "25", "50", "75", and "100" are the IL-33 Asthma PRS divided into quartiles and ranked from lowest to highest, the numbers "13102", "13102", "13104", and "13101" are the number of subjects in each group, and the numbers within each bar are the eosinophil counts. In the graph in panel B, the IL-33 Asthma PRS percentiles and the vertical axis are the relative difference in eosinophil counts. FIG. 8 shows that the IL33 PRS by the Ldpred method also shows a significant positive correlation with eosinophil counts.
[0118] Of the 543 variants in the IL-33 asthma PRS determined by LDpred training, 11 were disease or trait associated variants in HGMD. Variants in the IL-33 asthma PRS and interleukin-1 receptor ligand were found in the HGMD database and are associated with disease traits (Figure 9). The results of the analysis of the 543 variants are shown in Figure 9. The IL-33 asthma PRS and interleukin-1 receptor ligand were generated.
[0119] The IL-33 Asthma Polygenic Risk Score (IL-33AMR Asthma PRS) for Mixed-race American subjects determined using the LDpred methodology was significantly associated with asthma risk in Mixed-race American subjects in Mexico City. The graph shown in FIG. 10 shows how the IL-33 Asthma PRS for Mixed-race American patients predicts asthma risk in Mixed-race American patients in Mexico City. In the graph in Panel A, the IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, the numbers at the bottom of each bar are the number of subjects in each group, and the numbers in each bar are the percentage of asthmatic subjects. In the graph in Panel B, the IL-33 Asthma PRS percentiles and the vertical axis are the odds ratios for the percentage of asthmatic subjects. A highly significant association was observed. The results of this study were applied to the IL-33 Asthma PRS in clinical samples, combining both European and Mixed-race American samples to increase power. The plot in Figure 10 shows how the IL33 AMR asthma PRS acts on MCPS predicament asthma risk, with a highly significant association. This IL33 AMR PRS can be applied to clinical samples and combined with both EUR and AMR samples to increase power.
[0120] Six of the 205 variants in the IL-33 AMR asthma PRS determined by LDpred training were associated with HGMD disease or traits. Variants in the AMR IL-33 asthma PRS and interleukin-1 receptor ligand were found in the HGMD database and are associated with disease traits (Figure 11). The results of the analysis of 543 variants are shown in Figure 9. The IL-33 asthma PRS and interleukin-1 receptor ligand were generated. Figure 11 shows the IL33 PRS and IL4R PRS in clinical samples, and indicates that the IL4R PRS did not show a significant association with the efficacy endpoint.
[0121] In a clinical trial of itepekimab-treated mixed European and mixed American subjects, the IL-33 asthma PRS was determined by LDpred training. Figure 12 shows information on the number of variants and datasets used to generate the PRS (Panel A) and the distribution of PRS scores across samples for the European and mixed American subsets (Panel B).
[0122] The IL-33 Asthma PRS showed a trend towards a decreased risk of LOAC in itepekimab monotreated European and mixed race American subjects. The IL-33 Asthma PRS of mixed race American subjects was applied to 50 mixed race American samples from the itepekimab trial and combined with those of European subjects (Figure 13). The IL-33 Asthma PRS was divided into quartiles and ranked from lowest to highest, the number at the bottom of each bar is the number of subjects in each group, and the number on each bar is the percentage of subjects with LOAC. It was also observed that asthma patients with a high IL-33 Asthma PRS had less LOAC than those in the lowest quartile in the itepekimab monotherapy group. This finding suggests that asthma patients with high IL-33-based genetic risk may benefit more from itepekimab treatment. In the placebo group, the IL-33 Asthma PRS was observed to trend towards an increased LOAC. The findings suggest that asthma patients with high IL-33 PRS suffer from more LOAC.
[0123] The IL-33 asthma PRS was associated with increased baseline basophil counts in European subjects in trials named DRI12544 and EFC13579. The findings were significant with a p-value of 0.008 (Figure 14).
[0124] IL-33 Asthma PRS was significantly associated with increased asthma exacerbations in dupilumab-treated European subjects in trials named DRI12544 and EFC13579. Higher IL-33 Asthma PRS was associated with significantly increased asthma exacerbations in dupilumab-treated patients (Figure 15). IL-33 Asthma PRS was also associated with reduced changes in exotoxin 3 levels in the placebo group.
[0125] Mixed IL-33 asthma PRS determined with LDpred training for European and Mixed American subjects in trials named DRI12544 and EFC13579. Figure 16 shows information on the number of variants and datasets used to generate the PRS (Panel A) and the distribution of PRS scores across samples of European and Mixed American subjects (Panel B).
[0126] The IL-33 Asthma PRS was significantly associated with increased asthma exacerbation rates in dupilumab-treated mixed European and mixed American subjects in trials named DRI12544 and EFC13579. The European and mixed American samples were scored separately for each IL-33 Asthma PRS. The scores were then combined and regression analysis was performed on asthma exacerbation rates (Figure 17). In the graph in panel A, the IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, and the numbers within each bar are the annualized exacerbation rates. In the graph in panel B, the IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, and the numbers below each bar are the number of subjects in each group, and the vertical axis is the annualized exacerbation rate. These findings were replicated in European subjects, where the IL-33 Asthma PRS was significantly associated with increased exacerbations in the dupilumab group. Furthermore, based on IL-33 asthma PRS quartiles, the effect associated with dupilumab was significant for the 25th, 50th, and 75th quartiles, but not for the highest quartile. This suggests that the benefit of dupilumab comes primarily from asthma patients with low IL33 asthma PRS scores to dupilumab. Figure 17 shows that patients with IL-33 asthma PRS scores in the top 25% responded less effectively to dupilumab compared to patients with low IL-33 asthma PRS scores and treated with dupilumab.
[0127] IL-33 Asthma PRS was significantly associated with increased change in FEV1 at week 12 in mixed European and mixed American subjects on placebo in the trials named DRI12544 and EFC13579. IL-33 Asthma PRS was regressed against change in FEV1 at week 12 for the mixed European and mixed American sample. With increasing sample size, a significant association was observed between higher IL-33 Asthma PRS and increased FEV1 in the placebo group. This indicates that asthmatics with higher IL33 PRS benefited more from LABA or inhaled corticosteroids (graph in panel A of FIG. 18). In the graph in panel A, IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, and the number on each bar is the change in FEV1 at week 12. In the graph in Panel B, IL-33 Asthma PRS are divided into quartiles and ranked from lowest to highest, the numbers below each bar are the number of subjects in each group, and the vertical axis is the change in FEV1 at week 12. The graph in Panel B shows a replication of the findings in European patients, with patients with IL-33 Asthma PRS in the 25th and 50th quartiles having a more pronounced dupilumab response in terms of change in FEV1. Figure 18 shows that patients with IL-33 Asthma PRS scores in the bottom 25% of the dupilumab group had the greatest increase in FEV1 values compared to the placebo group.
[0128] There was an association between the change in IL-33 Asthma PRS and FVC at week 12 in European and mixed American subjects. Figure 19 shows the distribution of variants by sample. In the graph in Panel A, IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, and the number in each bar is the change in FEV1 at week 12. In the graph in Panel B, IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, the number under each bar is the number of subjects in each group, and the vertical axis is the change in FEV1 at week 12. Patients with IL-33 Asthma PRS scores in the top 25% respond less effectively to dupilumab compared to patients with lower IL-33 Asthma PRS scores and treated with dupilumab.
[0129] There was an association between the IL-33 Asthma PRS and the proportion of subjects with asthma exacerbations in GHS_GSA European subjects. The data shown in the graph in Panel A of Figure 20 demonstrates this finding. Panel A shows no association between the IL-33 Asthma PRS and the proportion of subjects with asthma exacerbations in GHS_GSA European subjects, and Panel B shows no association between the IL-33 Asthma PRS and the proportion of asthma subjects taking medication. In the graph in Panel A, the IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, the number at the bottom of each bar is the number of subjects in each group, and the number in each bar is the proportion of subjects with asthma exacerbations. There is an association between the IL-33 Asthma PRS and the proportion of asthma subjects taking medication. The data shown in the graph in Panel B of Figure 20 demonstrates this finding. In the graph in Panel B, IL-33 Asthma PRS are divided into quartiles and ranked from lowest to highest, the number below each bar is the number of subjects in each group, and the number within each bar is the percentage of asthma subjects taking medication. Figure 20 shows that patients with IL-33 Asthma PRS scores in the bottom 25% of the dupilumab group had the greatest increases in FEV1 values compared to the placebo group.
[0130] There was an association between the IL-33 Asthma PRS and the proportion of patients with Chronic Obstructive Pulmonary Disease (COPD) in GHS_GSA European patients. The graph shown in Figure 21 illustrates this result. The p-value was 7.75e-03. In this graph, the IL-33 Asthma PRS is divided into quartiles and ranked from lowest to highest, the numbers below each bar are the number of subjects in each group, and the numbers within each bar are the proportion of subjects with COPD.
[0131] GWAS data from individuals of European and mixed American ancestry were used to develop the PRS in this study. Polygenic risk scores for non-European populations will likely be improved over time as GWAS data become available for more diverse populations.
