TITLEBREAST CANCER DETECTION PROTEINS AND METHODS OF USE THEREOFCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims benefit of U.S. Provisional Application No. 63 / 616,327, filed on December 29, 2023, which is incorporated herein by reference in its entirety.BACKGROUND

[0002] Breast cancer remains a major health concern. While in women the incidence of some cancers such as lung cancer and colorectal cancer have declined, breast cancer continues to rise. In the U.S. alone, the estimated number of new cases for 2023 is nearly 300,000, which will account for over 30% of all cancers in women (Siegel et al.. 2023). The estimated number of deaths due to breast cancer in 2023 is over 43,000, which is behind only lung cancer as the cause of the most cancer-related deaths in women (id).

[0003] Early diagnosis for breast cancer has a significant impact on survival rate. Five-year survival rate of breast cancer patients decreases from over 99% if diagnosed at the localized stage (z.e., no sign that the cancer has spread outside the breast, approximately Stage I), to 86% if the cancer is diagnosed at the regional stage (z.e., cancer has spread from the breast to nearby structures or lymph nodes, approximately Stage II / III), and to 30% if the cancer is diagnosed at the distant stage (z.e., cancer has spread to distant parts of the body, approximately Stage IV) id.). The fact that a diagnosis when the breast cancer is localized is nearly 100% curable reflects the importance of having an effective means of diagnosing early stage breast cancer.

[0004] Early-stage breast cancer often causes no signs or symptoms, which emphasizes the importance of being about to screen and detect breast cancer. The most common screening procedure is a mammography, which is a low-dose x-ray diagnostic technique. However, a mammography can sometimes miss a cancer diagnosis (a falsenegative result) or incorrectly indicate presence of cancer (a false-positive result) (American Cancer Society, 2023). In addition, about 12% of women who are screened have abnormal results that require further testing, but only 4% of women with an abnormal mammogram have cancer (zt ). Additional concerns is the costs associated with mammograms; detectionof lesions that are not cancerous, which can lead to overdiagnosis and overtreatment; and the effects of cumulative radiation exposure over time from the mammograms (id.).

[0005] Therefore, there is an urgent unmet clinical need to improve the detection and diagnosis of breast cancer.SUMMARY OF THE INVENTION

The headings provided herein are not limitations of the various aspects or embodiments of the invention, which can be had by reference to the specification as a whole. Accordingly, the terms defined immediately below are more fully defined by reference to the specification in its entirety.

[0044] Wherever embodiments are described with the language “comprising,” otherwise analogous embodiments described in terms of “consisting of’ and / or “consisting essentially of’ are included.

[0045] An “effective amount” of a composition as disclosed herein is an amount sufficient to carry out a specifically stated purpose. An “effective amount” can be determined empirically and in a routine manner, in relation to the stated purpose, route of administration, and dosage form.

[0046] The term “subject” or “individual” or “patient” means any subject, preferably a mammalian subject, for whom diagnosis, prognosis, or therapy is desired. Mammalian subjects include humans, domestic animals, farm animals, sports animals, and zoo animals including, e.g., humans, non-human primates, dogs, cats, guinea pigs, rabbits, rats, mice, horses, cattle, and so on.

[0047] The term “early-stage” in the context of cancer (e.g., “early-stage cancer” or cancer that “is early-stage”) refers generally to a level of advancement of the cancer prior to the cancer spreading to lymph nodes or tissues that are distant from the tissue of origin. In some embodiments, an early-stage cancer can refer to a cancer that is a Stage 0, Stage I, or Stage II cancer, based on the stage classification known in the art that grades cancer from Stage 0 (e.g., carcinoma in situ, where the cancer is still only in the layer of cells where it started and has not advanced farther), through Stages I-III (e.g., cancer is present — the higher the number, the larger the tumor and the more it has spread into nearby tissues), and to Stage IV (e.g., the cancer has spread to distant parts of the body). In some embodiments, this stage classification incorporates the TNM System, which evaluates the cancer based on the size and extent of the main tumor (“T”), the number of nearby lymph nodes that have cancer (“N”), and the extent to which the cancer has metastasized (“M”).

[0048] The term “symptomatic” means to exhibit one or more signs or features that are regarded as indicative, or are known to be associated with, a disease or condition. A subject may be considered as “symptomatic” of cancer based on symptoms that are known in the art to be associated with cancer in general or for specific types of cancer. Examples include, but are not limited to, fatigue; lump or area of thickening that can be felt under the skin; weight changes, including unintended loss or gain; skin changes, such as yellowing, darkening, or redness of the skin, sores that will not heal, or changes to existing moles; changes in bowel or bladder habits; persistent cough or trouble breathing; difficulty swallowing; hoarseness; persistent indigestion or discomfort after eating; persistent, unexplained muscle or joint pain; persistent, unexplained fevers or night sweats; andunexplained bleeding or bruising. Symptoms that can occur with breast cancer in particular include, but are not limited to, a change in how the breast or nipple feels, such as nipple tenderness or a lump or thickening in or near the breast or underarm area, a change in the skin texture or an enlargement of pores in the skin of the breast, or a lump in the breast; a change in the appearance of the breast or nipple, such as any unexplained change in the size or shape of the breast, dimpling anywhere on the breast, unexplained swelling of the breast, unexplained shrinkage of the breast, recent asymmetry of the breasts, nipple that is turned slightly inward or inverted, or skin of the breast or areola or nipple that becomes scaly or red or swollen or may have ridges or pitting resembling the skin of an orange; any nipple discharge, in particular clear discharge or bloody discharge; or swollen lymph nodes under the arm or near the collar bone.

[0049] A subject may be considered as “suspected of having a cancer” due to the presence of symptoms, z.e., the subject is symptomatic; genetic markers; patient’s habits or medical history; patient’s family medical history; examination or tests known in the art for which the outcome is associated with cancer or risk of cancer, etc.

[0050] The term “asymptomatic” means to not exhibit any signs or features that are regarded as indicative, or are known to be associated with, a disease or condition.

[0051] Terms such as “treating” or “treatment” or “to treat” or “alleviating” or “to alleviate” refer to therapeutic measures that cure, slow down, lessen symptoms of, and / or halt progression of a diagnosed pathologic condition or disorder. Thus, those in need of treatment include those already with the disorder. In certain embodiments, a subject is successfully “treated” for a disease or disorder if the patient shows, e.g., total, partial, or transient alleviation or elimination of symptoms associated with the disease or disorder.

[0052] The term “ROC” or “ROC curve” is used to refer to a receiver operator characteristic curve. A ROC curve can be a graphical representation of the performance of a classifier system. For any given method, a ROC can be generated by plotting the sensitivity against the specificity. The sensitivity and specificity of a method for detecting the presence of a cancer or a specific type of cancer can be determined at various concentrations of proteins in a sample from the subject. The AUC of a ROC curve is a metric that can provide a measure of diagnostic utility of a method, taking into account both the sensitivity and specificity of the method. The AUC can range from 0.5 to 1.0, where a value closer to 0.5can indicate that the method has limited diagnostic utility (e.g., lower sensitivity and / or specificity) and a value closer to 1.0 indicates the method has greater diagnostic utility e.g., higher sensitivity and / or specificity).

[0053] The term “third party” means a person or group different from the two persons or groups primarily involved. For example, in a multi-step method involving a subject, a third party can be a person / group other than the subject and the person / group primarily responsible for the performance of the steps. In such an example, a third party may perform one of the steps in the method. As another example, in a treatment method involving administration of a treatment to a subject, a third party may be a person / group other than the subject and the person / group administering the treatment.

[0054] The term “cancer recurrence” refers to a return of cancer after a period of remission. The cancer can reappear in the same, or close to, the place that it was previously found (local recurrence); in the lymph nodes and tissue located in the vicinity of the original cancer (regional recurrence); or in areas farther away from the original cancer (distant recurrence).Methods of the Invention

[0090] In certain embodiments, a cancer patient subjected to a method of the invention is successfully treated if the patient’s survival is longer than the median survival of patients having breast cancer. Survival can be overall survival, z.e., length of time a patient lives, or progression-free survival, z.e., length of time a patient is treated without progression of the disease. Survival can be measured from the date of diagnosis or from the date that treatment commences. Overall survival, median overall survival, progression-free survival, and median progression-free survival can be determined by methods known in the art and / or by those described herein.

[0091] In certain embodiments a patient with breast cancer subjected to a method of the invention is successfully treated if the patient has an improved response to the anti-cancer therapy compared with a patient having breast cancer who has not been subjected to a method of the invention. For example, treatment of breast cancer would be successful in a subject treated by the methods of the invention if the subject has an improved response compared to the median response of patients who have not been treated by the methods of the invention.Response to anti-cancer treatment can be measured by known methods appropriate to the cancer type, for instance, using Response Evaluation Criteria in Solid Tumors (RECIST). Patients evaluated using RECIST can have a complete response (CR), a partial response (PR), stable disease (SD), or progressive disease (PD). An improved response can also be assessed by other criteria, for example, duration of response, reduction in tumor volume, minimum residual disease (MRD), and the like.Protein Concentration Measurement and Application of Classifiers

[0092] The concentration of proteins in the sample may be measured using protein quantitation techniques known in the art. Such techniques include, but are not limited to, enzyme-linked immunosorbent assays, chemiluminescence immunoassays, immunohistochemistry, liquid-bead immunoassays, mass spectrometry, aptamer-based assays, reverse phase protein arrays, proximity extension assay (PEA), and a combination thereof.

[0093] In the methods described herein, the concentration of the two or more proteins are used and combined with mathematical, statistical, and machine-learning methods to create secondary features. One or more proteins with and without secondary features and baseline features, including age, sex, race and ethnicity, past medical history, family history, patient’s lab values, comorbidities, and concomitant medications, are used in one or more predictive models to calculate a score.

[0094] Machine learning and statistical analyses techniques used to generate features and the final score for the cancer are included but not limited to the following concepts and methods: Supervised learning concepts may include AODE; Artificial neural network, such as B ackpropagation, Auto encoders, Hopfield networks, Boltzmann machines, Restricted Boltzmann Machines, and Spiking neural networks; Bayesian statistics, such as Bayesian network and Bayesian knowledge base; Case-based reasoning; Gaussian process regression; Gene expression programming; Group method of data handling (GMDH); Inductive logic programming; Instance-based learning; Lazy learning; Learning Automata; Learning Vector Quantization; Logistic Model Tree; Minimum message length (decision trees, decision graphs, etc.), such as Nearest Neighbor Algorithm and Analogical modeling; Probably approximately correct learning (PAC) learning; Ripple down rules, a knowledge acquisition methodology; Symbolic machine learning algorithms; Support vector machines; RandomForests; Ensembles of classifiers, such as Bootstrap aggregating (bagging) and Boosting (meta-algorithm); Ordinal classification; Information fuzzy networks (IFN); Conditional Random Field; ANOVA; Linear classifiers, such as Fisher’s linear discriminant, Linear regression, Logistic regression, Multinomial logistic regression, I Bayes classifier, Perceptron, Support vector machines; Quadratic classifiers; k -nearest neighbor; Boosting; Decision trees, such as C4.5, Random forests, ID3, CART, SLIQ SPRINT; Bayesian networks, sucINaive Bayes; and Hidden Markov models . Unsupervised learning concepts may include; Expectation -maximization algorithm; Vector Quantization; Generative topographic map; Information bottleneck method; Artificial neural network, such as Self - organizing map; Association rule learning, such as Apriori algorithm, Eclat algorithm, and FP growth algorithm; Hierarchical clusterings such as Single linkage clustering and Conceptual clustering; Cluster analysis, such as K -means algorithm, Fuzzy clustering, DBSCAN, and OPTICS algorithm; and Outlier Detection, such as Local Outlier Factor. Semi-supervised learning concepts may include; Generative models; Low -density separation; Graph-based methods, and Co -training. Reinforcement learning concepts may include Temporal difference learning; Q -learning, Learning Automata, and SARSA. Deep learning concepts may include Deep belief networks; Deep Boltzmann machines; Deep Convolutional neural networks; Deep Recurrent neural networks; and Hierarchical temporal memory.

[0095] For concentrations obtained from detection proteins, one or more features are fed into one or more computation models. The classifiers are used to calculate a score for the patient. The scores of different classifiers are combined to identify the patient as having the specific cancer or not. The computational model may use one or more proteins or secondary features with and without baseline features that could generate a (ROC curve greater than or equal to 0.6. This step determines if the sample indicates the presence of the cancer.

[0096] Protein concentrations and / or secondary features are fed into one or more predictive models. The features could be similar or different from what was used in determining cancer status. The classifiers are used to calculate a score for the patient for breast cancer. The predictive models use the proteins or derived secondary features that could generate a ROC curve greater than or equal to 0.6.

[0097] Generally, machine learning algorithms are used to construct models that accurately assign class labels to examples based on the input features that describe the example.

[0101] In some embodiments, the kit may also comprise one or more enzymes, substrates, labels, or other components useful for performing the assays.

[0102] In some embodiments, the kit further comprises one or more of the following: one or more containers for collecting or holding the sample (e.g., plasma sample), controls, directions for performing the methods, any necessary software for analysis and presentation of results.

[0103] One skilled in the art will readily recognize that the disclosed one or more components can be readily incorporated into any of the established kit formats that are well known in the art.EXAMPLE

[0104] Analyses were performed to identify the breast cancer detection proteins of the present invention.Sample CollectionPlasma samples were collected from a patient population diagnosed with breast cancer, and from healthy individuals without breast cancer.Protein Measurement

[0105] While any protein measurement technique could have been used, including enzyme-linked immunosorbent assays (ELISA), chemiluminescence immunoassays (CLIA), immunohistochemistry (IHC), liquid-bead immunoassays, mass spectrometry, aptamer-based assays, reverse phase protein arrays (RPPA), etc., a proximity extension assay (PEA) was employed to evaluate proteins in urine. In PEA, each protein was recognized by two antibodies for proper detection. In proximity assays, each of the two antibodies was conjugated to one of two different DNA oligonucleotides, and the reagents were incubated with the samples in solution. The proximity reactions underwent a dilution step.Oligonucleotides on pairs of antibodies that remain in proximity by virtue of having bound the same protein molecule then underwent DNA ligation (proximity ligation assay) or DNA polymerization (proximity extension assay). The effect of the ligation or polymerization reactions was to create amplifiable reporter DNA strands for sensitive readout via, for example, real-time PCR or next-generation sequencing, and the assays could be performed in high multiplex. By constructing the assays so that only proper pairs of antibodies can yield detection signals, but no other combination of antibodies, the detection of many different proteins in parallel was possible without eroding detection specificity by reactions of noncognate pairs.

[0106] The analytical performance of the panels was validated for sensitivity, dynamic range, specificity, precision, and scalability. The analytical measuring range was defined by the lower limit of quantification (LLOQ) and upper limit of quantification(ULOQ) and reported in pg / mL. The high dose hook effect (a state of antigen excess relative to the reagent antibodies resulting in falsely lower values) was also determined for each analyte.

[0107] All assays were thoroughly validated for precision (repeatability and reproducibility). Intra-assay variation (within-run) was calculated as the mean CV for individual samples, within each of separate runs during the validation studies. Inter-assay variation (between-runs) was calculated as the mean CV, for the same individual samples, among separate runs during the validation studies.

[0108] Each protein analyte was addressed by a matched pair of antibodies, coupled to unique, partially complementary oligonucleotides and measured by quantitative real-time PCR. Validation of the readout specificity for all of the panels was carried out using a simple, sequential approach in which pools of protein analytes were tested.Feature Selection

[0109] Proteins were used to create features that could be used for the classification of samples. The proteins were categorized based on their concentration or their patterns of change detected by different statistical or machine-learning techniques to create new features.

[0110] Machine learning and statistical analyses techniques used to generate features and the final score for the cancer were included but not limited to the following concepts and methods: supervised learning concepts that may include AODE; artificial neural network, such as Backpropagation, Auto encoders, Hopfield networks, Boltzmann machines, Restricted Boltzmann Machines, and Spiking neural networks; Bayesian statistics, such as Bayesian network and Bayesian knowledge base; case-based reasoning; Gaussian process regression; gene expression programming; group method of data handling (GMDH); inductive logic programming; instance-based learning; lazy learning; learning Automata; learning vector quantization; logistic model tree; minimum message length (decision trees, decision graphs, etc.), such as nearest neighbor algorithm and analogical modeling; probability approximately correct learning (PAC) learning; ripple down rules, a knowledge acquisition methodology; symbolic machine learning algorithms; support vector machines; random forests; ensembles of classifiers, such as bootstrap aggregating (bagging) and boosting (meta-algorithm); ordinal classification; information fuzzy networks (IFN); conditional random field; ANOVA; linear classifiers, such’as Fisher's linear discriminant,linear regression, logistic regression, multinomial logistic relion, naive Bayes classifier, Perceptron, support vector machines; quadratic classifiers; k -nearest neighbor; boosting; decision trees, such as C4.5, random forests, ID3, CART, SLIQ SPRINT; Bayesian netl, such as Naive Bayes; and Hidden Markov models. cUnsupervised learning concepts may include; expectation -maximization algorithm; vector quantization; generative topographic map; information bottleneck method; artificial neural network, such as self -organizing map; association rule learning, such as Apriori algorithm, Eclat algorithm, and FP growth algorithm; hierarchical clusterings such as single linkage clustering and conceptual clustering; cluster analysis, such as K -means algorithm, fuzzy clustering, DBSCAN, and OPTICS algorithm; and outlier detection, such as local outlier factor. Semi -supervised learning concepts may include: generative models; low-density separation; graph-based methods, and co -training. Reinforcement learning concepts may include temporal difference learning; Q -learning, learning automata, and SARSA. Deep learning concepts may include deep belief networks; deep Boltzmann machines; deep convolutional neural networks; deep recurrent neural networks; and hierarchical temporal memory.Breast Cancer Detection Proteins

[0111] One or more features were fed into one or more computation models. The classifiers were used to calculate a score for the patient. The scores of different classifiers were combined to identify the patient as having breast cancer or not. The computational model only selected protein or protein combinations that could generate a receiver operating characteristic (ROC) curve of greater than or equal to 0.6.

[0112] Table 1 lists proteins that can detect breast cancer. In particular, Table 1.A shows a full list of the breast cancer detction proteins and their individual AUC, and Table l.B, Table l.C, Table l.D, Table l.E, Table l.F, Table l.G, Table l.H, or Table 1.1 show partticular subsets of proteins of Table 1.A, Analysis of the proteins in Table l.A showed that the accuracy for detecting breast cancer was about 0.7 or above when any two proteins through any 15 proteins were randomly selected (see FIG. 1). Further, a panel of all proteins in Table 1.A was shown to have high diagnostic utility in detecting breast cancer, as the AUC of ROC curves generated using two different classifiers — a first classifier and a second classifier — was each over 0.92 (see FIG. 2, Panels A and B). Simiarly, a panel of all proteins in the subsets shown in Table l.B, Table l.C, Table l.D, Table l.E, Table l.F,Table l.G, Table 1.H, and Table 1.1 also exhibited high diagnostic utiltiy, as the AUC of a ROC curve generated using the first classifier and the AUC of a ROC curve geneated by the second classifier were each over 0.77, as shown in FIGS. 3-10, respectively, and in Table 2.Table 1. Proteins for detection of breast cancer.Table 2. AUC of ROC curves generated by application of the first classifier and the second classifier using the protein panels set forth in Table l.A - Table 1.1 for detecting breast cancer in subjects.EMBODIMENTS
