參考用於說明的示例應用在下文中描述本發明的數個方面。應當理解的是,陳述許多具體細節、關係和方法來提供對本發明的充分理解。然而,在相關領域的普通技術人員將容易地認識到,可在不含一個或多個具體細節的情況下實施本發明或者可用其他方法來實施本發明。
本發明涉及新發現的生物標誌物(即RBM10)的突變和/或表現與西奧羅尼的療效、西奧羅尼的用藥和/或卵巢癌的治療效果之間的關係。本文所述生物標誌物提供用於評價西奧羅尼療效、指導西奧羅尼用藥和/或預測卵巢癌治療效果的方法。因此,本發明的一個實施方案代表生物標誌物的改進,所述腫瘤標誌物適用於評價西奧羅尼療效、指導西奧羅尼用藥和/或預測卵巢癌治療效果。在又一個實施方案中,本發明新發現的生物標誌物(即RBM10)可與本領域已知的一種或多種其它癌症標誌物(例如CEA、NSE、CA 19-9、CA 125、CA 72-4、PSA、proGRP、SCC、NNMT、VEGFR2、HER2、MISIIR、VEGFA、CD24)聯用,例如用於評價西奧羅尼療效、指導西奧羅尼用藥和/或預測卵巢癌治療效果或用於製備用於此目的的套組。
本發明通過以患者的無進展生存期(PFS)作為療效指標,驗證了RBM10基因變異與西奧羅尼療效的關聯性,對RBM10基因突變資訊的檢測,可以指導西奧羅尼的臨床用藥和評價其對腫瘤治療的療效,尤其適用於卵巢癌,特別適用於復發、晚期的卵巢癌。
在本發明中,“西奧羅尼的療效較佳、能夠使用西奧羅尼治療或者卵巢癌治療效果較好”尤其是指西奧羅尼能夠顯著延長患者例如卵巢癌患者的無進展生存期(PFS)。在某些實施方案中,本發明的套組用於評價西奧羅尼對治療卵巢癌的療效和/或指導西奧羅尼用於治療卵巢癌的用藥。
術語“樣品”意指已知或疑似表現或含有生物標誌物(即RBM10)或結合劑的材料,結合劑為例如對生物標誌物(即RBM10)有特異性的抗體。樣品可來源於生物來源(“生物樣品”),例如組織(例如活組織檢查樣品)、提取物或包括細胞(例如腫瘤細胞)、細胞裂解物在內的細胞培養物和生物或生理流體,例如全血、血漿、血清、唾液、腦髓液、汗、尿液、乳汁、腹膜液等。獲自來源的樣品或在預處理以改進樣品特徵(例如從血液製備血漿、稀釋黏液等)後的樣品可直接使用。在本發明的某些方面,樣品是人生理流體,例如人血清。在本發明的某些方面,樣品是活組織檢查樣品例如經組織檢查獲得的腫瘤組織或細胞。在本發明的某些方面,樣品是惡性或正常組織樣品例如癌旁正常組織樣品。

以上所述僅是本發明的優選實施方式,應當指出,對於本技術領域的普通技術人員來說,在不脫離本發明原理的前提下,還可以做出若干改進和潤飾,這些改進和潤飾也應視為本發明的保護範圍。Several aspects of the invention are described below with reference to example applications for illustration. It should be understood that numerous specific details, relationships and methods are set forth to provide a thorough understanding of the present invention. However, one of ordinary skill in the relevant art will readily recognize that the invention may be practiced without one or more of the specific details or in other ways. The present invention relates to the relationship between the mutation and/or expression of a newly discovered biomarker (ie RBM10) and the efficacy of cioronib, the administration of cioronib and/or the therapeutic effect of ovarian cancer. The biomarkers described herein provide methods for evaluating the efficacy of cioronib, guiding the administration of cioronib, and/or predicting the effect of treatment in ovarian cancer. Thus, one embodiment of the present invention represents an improvement in biomarkers suitable for evaluating the efficacy of cioronib, guiding the administration of cioronib and/or predicting the effect of ovarian cancer treatment. In yet another embodiment, the newly discovered biomarkers of the present invention (ie, RBM10) may be combined with one or more other cancer markers known in the art (eg, CEA, NSE, CA 19-9, CA 125, CA 72- 4. Combination of PSA, proGRP, SCC, NNMT, VEGFR2, HER2, MISIIR, VEGFA, CD24), for example, for evaluating the efficacy of cioronib, guiding the administration of cioronib and/or predicting the treatment effect of ovarian cancer or for A kit is prepared for this purpose. The invention verifies the correlation between the RBM10 gene variation and the curative effect of cioroni by taking the patient's progression-free survival (PFS) as the curative effect index, and the detection of the RBM10 gene mutation information can guide the clinical medication and treatment of cioroni. To evaluate its curative effect on tumor treatment, especially for ovarian cancer, especially for recurrent and advanced ovarian cancer. In the present invention, “the curative effect of cioronib is better, the treatment effect of cioronib can be better, or the treatment effect of ovarian cancer is better” especially refers to that cioronib can significantly prolong the progression-free survival period of patients such as ovarian cancer patients (PFS). In certain embodiments, the panels of the present invention are used to evaluate the efficacy of cioronib for the treatment of ovarian cancer and/or to guide the administration of cioronib for the treatment of ovarian cancer. The term "sample" means a material known or suspected to express or contain a biomarker (ie RBM10) or a binding agent, eg an antibody specific for the biomarker (ie RBM10). Samples may be derived from biological sources ("biological samples"), such as tissues (eg, biopsy samples), extracts or cell cultures including cells (eg, tumor cells), cell lysates, and biological or physiological fluids, such as Whole blood, plasma, serum, saliva, cerebrospinal fluid, sweat, urine, milk, peritoneal fluid, etc. Samples obtained from sources or after pretreatment to improve sample characteristics (eg, preparation of plasma from blood, dilution of mucus, etc.) can be used directly. In certain aspects of the invention, the sample is a human physiological fluid, such as human serum. In certain aspects of the invention, the sample is a biopsy sample such as tumor tissue or cells obtained by tissue examination. In certain aspects of the invention, the sample is a malignant or normal tissue sample such as a paracancerous normal tissue sample. Samples that can be analyzed in accordance with the present invention include polynucleotides of clinical origin. As will be understood by those of skill in the art, target polynucleotides can include RNA, including, but not limited to, total cellular RNA, poly(A)+ messenger RNA (mRNA) or a portion thereof, cytoplasmic mRNA, or RNA transcribed from cDNA ( i.e. cRNA). The target polynucleotide can be detectably labeled on one or more nucleotides using methods known in the art. Detectable labels can be, without limitation, luminescent, fluorescent, bioluminescent, chemiluminescent, radioactive, and colorimetric labels. The term "marker" as used herein refers to a molecule to be used as a target for analyzing a patient's experimental sample. Examples of such molecular targets are genes, proteins or polypeptides. The genes, proteins or polypeptides used as markers in the present invention are intended to include naturally occurring variants of said genes or proteins as well as fragments of said genes or proteins or said variants, particularly immunologically detectable fragments . Immunologically detectable fragments preferably comprise at least 6, 7, 8, 10, 12, 15 or 20 contiguous amino acids of the marker polypeptide. One skilled in the art will recognize that proteins released by cells or present in the extracellular matrix may be damaged (eg, during inflammation) and may be degraded or cleaved into such fragments. Certain markers are synthesized in an inactive form, which can then be initiated by proteolysis. As the skilled artisan will appreciate, proteins or fragments thereof can also be present as part of a complex. Such complexes can also be used as markers in the sense of the present invention. Variants of marker polypeptides are encoded by the same gene, but may differ in their isoelectric point (=PI) or molecular weight (=MW) or both, e.g. as a result of alternative mRNA or pre-mRNA processing . The amino acid sequence of the variant is 95%, 96%, 97%, 98%, 99% or more identical to the corresponding marker sequence. Additionally, or in the alternative, marker polypeptides or variants thereof may carry post-translational modifications. Non-limiting examples of post-translational modifications are glycosylation, acylation and/or phosphorylation. The performance of the marker can also be identified by detecting translation of the marker (ie, detection of the marker protein in the sample). Methods suitable for detecting marker proteins include any suitable method for detecting and/or measuring proteins from cells or cell extracts. Such methods include, but are not limited to, immunoblotting (eg, Western blotting), enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), immunoprecipitation, immunohistochemistry, and immunofluorescence. Particularly preferred methods for detecting proteins include any cell-based assay, including immunohistochemistry and immunofluorescence assays. Such methods are well known in the art. The terms "subject", "patient" and "individual" are used interchangeably herein to refer to a warm-blooded animal, such as a mammal. The term includes, but is not limited to, livestock, rodents (eg, rats and mice), primates, and humans. Preferably the term refers to humans. RBM10 (NG_012548.1) belongs to a family of RNA motif-binding proteins, located on chromosome Xp11.23, encoding a 930 amino acid nucleoprotein with two RNA recognition domains (RRMs) and two zinc finger structures domain and a G-patch domain. This gene is also known as DXS8237E, GPATC9, GPATCH9, S1-1, TARPS and ZRANB5. The term "wild-type" is to be understood according to the general understanding of those skilled in the art and refers to a nucleic acid or amino acid sequence in its naturally occurring form without any artificial mutation, nucleotide change or amino acid modification. The term "mutant" should be understood according to the general understanding of those skilled in the art. A nucleic acid sequence is referred to as "mutated" if it contains at least one nucleotide addition, deletion or substitution in its nucleic acid sequence compared to its native or native nucleic acid sequence, ie if it contains a nucleic acid mutation. If the amino acid sequence contains at least one added, deleted or substituted amino acid in its amino acid sequence compared to its natural or native amino acid sequence, i.e. if it contains an amino acid mutation, then called "mutated". In the present invention, the variation of the RBM10 gene or its mRNA refers to the mutation in the wild-type RBM10 gene or its mRNA, which includes addition, deletion and substitution of one or more nucleotides and changes in copy number (including amplification and missing). The nucleotides may be nucleotides of a coding region or a non-coding region. The coding region may be a nucleotide sequence encoding an RNA recognition domain (RRM), a zinc finger domain and/or a G-patch domain. The variation of the RBM10 gene or its mRNA can lead to an increase or decrease in the expression level of the RBM10 gene and/or an amplification or deletion of the copy number. For example, the level or copy number is at least about 1.1, 1.25, 1.5, 2, 3, 4, 5, 6, 7, 8, 9 or 10 times or more of the control or standard, respectively or at most about 1 of the control or standard /1.1, 1/1.25, 1/1.5, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8, 1/9 or 1/10 or less. Copy number amplifications or deletions can be detected by techniques well known in the art, such as whole gene sequencing. In the present invention, the variation of the protein or protein fragment encoded by the RBM10 gene includes: 1) mutations in the protein or protein fragment encoded by the wild-type RBM10 gene, which include addition, deletion or substitution of one or more amino acids; and 2) changes in the expression level of the protein encoded by the wild-type RBM10 gene. The amino acid may be an amino acid of an RNA recognition domain (RRM), a zinc finger domain and/or a G-patch domain. The protein fragments refer to polypeptides having amino-terminal deletions, carboxy-terminal deletions and/or intermediate deletions compared to the full-length native protein. The fragments may also contain modified amino acids compared to the native protein. In certain embodiments, the fragments are about 5-500 amino acids in length. For example, fragments can be at least 5, 6, 8, 10, 14, 20, 50, 70, 100, 110, 150, 200, 250, 300, 350, 400, or 450 amino acids in length. In one embodiment, the fragment is an immunologically detectable fragment preferably comprising at least 6, 7, 8, 10, 12, 15 or 20 contiguous amino acids of the marker polypeptide. The change in the expression level of the protein refers to at least about 1.1, 1.25, 1.5, 2, 3, 4, 5, 6, 7, 8, 9 or 10 times or more or at most about 1/1.1, 1/1.25, 1/1.5, 1/2, 1/3, 1/4, 1/5, 1/6 of the performance level of a control or standard , 1/7, 1/8, 1/9 or 1/10 or less. The terms "polypeptide" and "protein" are used interchangeably herein to refer to at least one molecular chain of amino acids linked by covalent and/or non-covalent bonds. The term includes post-translational modifications of peptides, oligopeptides, and proteins and polypeptides, such as glycosylation, acetylation, phosphorylation, and the like. Protein fragments, analogs, muteins or variant proteins, fusion proteins, etc. are also included within the meaning of the term. In certain embodiments, determining "protein expression levels,""geneexpression," or "gene expression levels" as used herein includes, but is not limited to, determining corresponding RNA, protein, or peptide levels (or combinations thereof). The present invention is not limited to specific methods and reagents for measuring protein, peptide or RNA levels, all of which are well known in the art. Methods for determining the amount or concentration of protein in a sample are known to the skilled artisan. Such methods include radioimmunoassays, competitive binding assays, Western blot analysis and ELISA assays. For methods using antibodies, both monoclonal and polyclonal antibodies are suitable. The antibody may be immunologically specific for a protein, protein epitope or protein fragment. The term "oligonucleotide" refers to a polymeric form of nucleotides of any length, either ribonucleotides or deoxyribonucleotides. The term includes double- and single-stranded DNA and RNA, modified and unmodified forms such as methylation or capping of polynucleotides. The terms "polynucleotide" and "oligonucleotide" are used interchangeably herein. An oligonucleotide may, but need not, include other coding or non-coding sequences, or it may, but need not, be linked to other molecules and/or vectors or support materials. The oligonucleotides used in the methods or kits of the present invention can be of any length suitable for the particular method. In certain applications, the term refers to an antisense nucleic acid molecule (eg, an mRNA or DNA strand in the opposite orientation to a sense polynucleotide encoding a cancer marker of the invention (eg, RBM10)). Oligonucleotides for use in the present invention include complementary nucleic acid sequences and nucleic acids substantially identical to those sequences, and also include sequences that differ from nucleic acid sequences due to the degeneracy of the genetic code. Oligonucleotides useful in the present invention also include nucleic acids that hybridize to oligonucleotide cancer marker nucleic acid sequences under stringent conditions, preferably high stringency conditions. Nucleotide hybridization assays are well known in the art. Hybridization assay protocols and conditions will vary depending on the application and are chosen according to known general binding methods, see eg, J. Sambrook et al., Molecular Cloning: A Laboratory Guide (Third Edition. Science Press, 2002); and Young and Davis , PNAS, 80: 1194 (1983). Methods and apparatus for performing repetitive and controlled hybridization reactions have been described in US Pat. Nos. 5,871,928, 5,874,219, 6,045,996, 6,386,749, and 6,391,623, each of which is incorporated herein by reference. In some cases, it may be necessary to amplify the sample. Genomic samples can be amplified by various mechanisms, some of which can employ PCR. Samples can be amplified on the array. See, eg, US Patent No. 6,300,070 and US Patent Application Serial No. 09/513,300.

Nos. 5,409,818, 5,554,517 and 6,063,603, each of which is incorporated herein by reference). Reagents that can be used to detect RBM10 expression levels and/or copy number are well known in the art. Such reagents suitable for use in the present invention are commercially available or routinely prepared by methods well known to those skilled in the art. The term "binding agent" refers to substances such as polypeptides, antibodies, ribosomes or aptamers that specifically bind to the biomarkers of the invention (RBM10). A substance "specifically binds" to a biomarker of the invention if it reacts at a detectable level with the biomarker of the invention but not a peptide containing an unrelated sequence or a sequence of a different polypeptide. Binding properties can be assessed using an ELISA that can be readily performed by those skilled in the art. The binding agent may be a ribosome, RNA or DNA molecule or polypeptide with or without a peptide component. The binding agent may be a polypeptide comprising a polypeptide biomarker sequence, a peptide variant thereof, or a non-peptide mimetic of such a sequence. Aptamers include DNA or RNA molecules that bind nucleic acids and proteins. Aptamers that bind the markers of the present invention can be generated using conventional techniques without undue experimentation. [See, for example, the following publications describing in vitro selection of aptamers: Klug et al., Mol. Biol. Reports 20:97-107 (1994); Wallis et al., Chem. Biol. 2:543-552 (1995); Ellington, Curr. Biol. 4:427-429 (1994); Lato et al., Chem. Biol. 2:291-303 (1995); Conrad et al., Mol. Div. 1:69-78 (1995); and Uphoff et al., Curr. Opin . Struct.

A microarray refers to a solid support with a flat surface having an array of nucleic acids, each member of the array comprising identical copies of oligonucleotides or polynucleotides immobilized on spatially defined regions or sites, The regions or bitpoints do not overlap with regions or bitpoints of other members in the array; that is, the regions or bitpoints are spatially discrete. Furthermore, a spatially defined hybridization site may be "addressable" in that its location and the identity of its immobilized oligonucleotide are known or predetermined (eg, known or predetermined prior to its use) of). Typically the oligonucleotide or polynucleotide is single stranded and is usually covalently attached to a solid support from either the 5'- or 3'-end. The density of nucleic acids containing non-overlapping regions in the microarray is typically greater than 100/cm 2 , more preferably greater than 1000/cm 2 . Microarray technology is disclosed, for example, in the following references: Microarrays: A Practical Approach, edited by Schena (IRL Press, Oxford, 2000); Southern, Current Opin. Chem.

Example 1 : Cioronib Monotherapy for Relapsed and Refractory Ovarian Cancer Phase Ib Clinical Trial Test Drug: Cioroni Capsules, Specifications: 5mg, 25mg. Produced by Shenzhen Microchip Biotechnology Co., Ltd. Dosing regimen: Cioroni capsules were administered at 50 mg/day, QD (no adjustment for body weight or body surface area). Take each morning on an empty stomach, with water, and swallow the capsule whole. Continuous administration for 28 days is one treatment cycle, and there is no interval between each treatment cycle. Number of cases: 25 patients were enrolled, of which 23 patients were evaluated for efficacy. Inclusion criteria: 1. Age ≥18 years old, ≤70 years old, female; 2. Histologically diagnosed epithelial ovarian cancer, fallopian tube cancer or primary peritoneal cancer; 3. Subjects must have received platinum-based chemotherapy regimens , that is, a) platinum-resistant patients (disease progression or recurrence ≤6 months after the end of platinum-containing chemotherapy regimens), should have received at least 2 different chemotherapy regimens after disease progression or recurrence; b) if platinum-sensitive patients ( Disease progression or recurrence > 6 months after the end of platinum-based chemotherapy regimen), disease progression or recurrence after receiving at least 2 chemotherapy regimens, or the subject refuses to receive further chemotherapy; 4. According to RECIST1.1 criteria, at least A measurable target lesion; 5. ECOG physical fitness score of 0-1; 6. The interval from the end of the previous chemotherapy, radiotherapy, targeted therapy, immunotherapy or study drug treatment should be more than 4 weeks, if the chemotherapy regimen includes mitosis 7. The main organ functions meet the following criteria: Blood routine: absolute value of neutrophils ≥ 1.5×10 9 /L, platelets ≥ 90×10 9 /L, hemoglobin ≥ 90g/L ; Blood biochemistry: total bilirubin ≤ 1.5 times the upper limit of the reference range (ULN), AST, ALT ≤ 2 times ULN (liver metastases: ≤ 5 times ULN); serum creatinine ≤ 1.5 times ULN; coagulation function: thrombin Original time-international normalized ratio (PT-INR) ≤ 1.5 times ULN. 8. Expected survival time ≥ 3 months; 9. Voluntarily signed a written informed consent. Treatment plan: test subjects take cioroni capsules 50 mg orally once a day, every 28 days as a treatment cycle, and there is no stopping interval between treatment cycles. Throughout the trial, all subjects continued treatment until any of the following occurred (whichever occurred first): disease progression, intolerable toxicity, death, withdrawal of informed consent, or loss to follow-up. Efficacy evaluation: According to RECIST1.1 criteria, the evaluation was performed at the baseline and the 4th week after treatment, and repeated every 8 weeks until disease progression. Tumor imaging examinations include CT or MRI of the neck, chest, whole abdomen, and pelvis. Examinations of other parts are performed according to clinical indications and when necessary. The same techniques and methods should be used for baseline and follow-up assessment of lesions. Safety assessment: including physical examination, vital signs, ECOG performance score, blood routine, urine routine, 12-lead ECG, blood biochemistry, electrolytes, coagulation function, cardiac enzymes, troponin, TSH, FT3, FT4, amylase, Echocardiography, 24-hour urine protein quantification (if necessary), adverse events. Biomarker study: 10 ml of peripheral blood was taken before the subjects took cioroni for the first time and when the disease progressed, and the gene sequence of plasma cell-free tumor DNA (ctDNA) and leukocyte extracted DNA (control) were detected, including a total of 548 A tumor-related gene, and the test results include gene mutation and copy number abnormality. Clinical Trial Results: Of the 25 subjects, 2 had no post-baseline efficacy assessment results, resulting in 23 evaluable cases. Among the 23 evaluable subjects, the best response during the trial was: 2 (8.7%) PR (of which 1 was confirmed at follow-up assessment), 14 (60.9%) SD, 7 (30.4%) PD , the confirmed ORR was 4.3% and the unconfirmed ORR was 8.7%. Of the 23 evaluable subjects, 3 were platinum-sensitive and 20 were platinum-resistant. Both PR subjects were platinum-resistant subjects, and the confirmed response was 1 (5.0%). The results show that cioronib monotherapy is effective in ovarian cancer. A concomitant study of efficacy-related biomarkers was performed on 548 tumor-related genes for the detection and analysis of cell-free tumor DNA (ctDNA) in the plasma of the evaluated patients. The detection results selected all genes with a mutation rate of more than 0.4%, and took the patient's progression-free survival (PFS) as the efficacy indicator to analyze the correlation between tumor-related gene abnormalities and the efficacy of cioronib. The results showed that among 548 tumor-related genes, a gene mutation that was significantly correlated with the efficacy of cioronib was found, which was the RBM10 gene. The median PFS was 232 days in 7 of the 23 evaluable subjects with RBM10 mutations (30.4%; these mutations included nucleotide additions, deletions and substitutions, and copy number changes) and 16 with RBM10 wild-type (69.6%). The median PFS of ) was 106 days, and there was a significant difference between the two groups, suggesting that the RBM10 gene is associated with the efficacy of cioronib in the treatment of ovarian cancer and can be a potential biomarker for evaluating the efficacy. See Table 1 and Figure 1 for the results. The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. It should be regarded as the protection scope of the present invention.
