Title: Use of peptidylglycine alpha-amidating monooxygenase (pam) for therapeutic purpose

Description:
The present invention is directed to the use of peptidylglycine alpha-amidating monooxygenase (PAM) as medicament. 
     STATE OF THE ART 
     Biologically active peptide hormones fulfill the function as signaling molecules. Most bioactive peptide hormones are synthesized from larger, inactive precursor peptides. During their biosynthesis, those peptides undergo several co- and posttranslational modifications, including cleavage of signal peptides, endoproteolytic cleavage of the precursor pro-peptides by specific endopeptidases mostly at pairs of basic residues, removal of basic residues by carboxypeptidases, formations of disulfide bonds and N- and O-glycosylation (Eipper et al. 1993 . Protein Science  2(4): 489-97). More than half of the known neural and endocrine peptides require an additional modification step to gain full biological activity involving the formation of a c-terminal alpha-amide group (Guembe, et al. 1999 . J Histochem Cytochem  47(5): 623-36). This final step of peptide hormone biosynthesis involves the action of the bifunctional enzyme peptidylglycine alpha-amidating monooxygenase (PAM). PAM specifically recognizes c-terminal glycine residues in its substrates, cleaves glyoxylate from the peptide&#39;s c-terminal glycine residue in a two-step enzymatic reaction leading to the formation of c-terminally alpha-amidated peptide hormones, wherein the resulting alpha-amide group originates from the cleaved c-terminal glycine (Prigge et al. 2004 . Science  304(5672): 864-67). This amidation reaction takes place in the lumen of secretory granules prior to exocytosis of the amidated product (Martinez and Treston 1996 . Molecular and Cellular Endocrinol  123: 113-17). Alpha-amidated peptides are for example adrenomedullin, substance P, vasopressin, neuropeptide Y, Amylin, calcitonin, neurokinin A and others. However, previously it was demonstrated that PAM can also catalyze the formation of alpha-amides from glycinated substrates of non-peptide character, e.g. N-fatty acyl-glycines, which are converted by PAM to primary fatty acid amides (PFAMs) like oleamide. The identified and purified peptidyl-glycine amidating activities were shown to be dependent on copper and ascorbate (Emeson et al. 1984 . Journal of Neuroscience:  2604-13; Kumar et al. 2016  J Mol Endocrinol  56(4):T63-76; Wand et al. 1985.  Neuroendocrinology  41: 482-89). 
     In humans, the PAM gene is located at chromosome 5q21.1 having a length of 160 kb containing 25 known exons (Gaier et al. 2014 . BMC Endocrine Disorders  14). At least 6 isoforms are known to be generated by alternative splicing (SEQ ID 1-6). The PAM enzyme was found to be expressed at different levels in almost all mammalian cell types, with significant expression in airway epithelium, endothelial cells, ependymal cells in the brain, adult atrium, brain, kidney, pituitary, gastrointestinal tract and reproductive tissues (Chen et al. 2018 . Diabetes Obes Metab  20  Suppl  2:64-76; Oldham et al. 1992.  Biochem Biophys Res Commun  184(1): 323-29; Schafer et al. 1992 . J Neurosci  12(1): 222-34). 
     However, the highest human PAM activity was described in the pituitary, the stalk and hypothalamus. The plasma amidating activity of healthy children below 15 years was significantly higher than that of healthy adults (Wand et al. 1985  Metabolism  34(1): 1044-52). 
     The precursor protein (1-973 amino acids) of the largest known PAM Isoform 1 (SEQ ID No. 1) encoded by the PAM cDNA is depicted in  FIG.  1   . The N-terminal signal sequence (amino acids 1-20) assures direction of the nascent PAM polypeptide into the secretory lumen of endoplasmic reticulum and is subsequently cleaved co-translationally. Afterwards the PAM-pro-peptide is processed by the same machinery used for the biosynthesis of integral membrane proteins and secreted proteins including cleavage of the pro-region (amino acids 21-30), assuring proper folding, disulfide bond formation, phosphorylation and glycosylation (Bousquet-Moore et al. 2010 . J Neurosci Res  88(12):2535-45). 
     As depicted in  FIG.  1   , the PAM cDNA further encodes two distinct enzymatic activities. The first enzymatic activity is named peptidyl-glycine alpha-hydroxylating monooxygenase (PHM; EC 1.14.17.3), is an enzyme, capable of catalyzing the conversion of a C-terminal glycine residue to an alpha-hydroxy-glycine. The second activity is named peptidyl-a-hydroxy-glycine alpha-amidating lyase (PAL; EC 4.3.2.5) is an enzyme capable of catalyzing the conversion of an alpha-hydroxy-glycine to an alpha-amide with subsequent glyoxylate release. The sequential action of these separate enzymatic activities results in the overall peptidyl-glycine alpha amidating activity. The first enzymatic activity (PHM) is located directly upstream of the pro-region (within of amino acids 31-494 of isoform 1 (SEQ ID No. 7)). The second catalytic activity (PAL) is located after exon 16 in isoform 1 within of amino acids 495-817 (SEQ ID No. 8). 
     As depicted in  FIG.  2   , both activities may be encoded together within of one polypeptide as a membrane-bound protein (isoforms 1, 2, 5, 6; corresponding to SEQ ID No. 1, 2, 5 and 6) as well within of one polypeptide as a soluble protein lacking the transmembrane domain (isoforms 3 and 4; corresponding to SEQ ID No. 3 and 4). While isoforms 1, 2, 5 and 6 remain in the outer plasma membrane after fusion of secretory vesicles with the plasma membrane with subsequent endocytosis and recycling or degradation, soluble PAM isoforms lacking the TMD (isoforms 3 and 4) (amino acids 864-887) are co-secreted with the peptide-hormones (Wand et al. 1985  Metabolism  34(11): 1044-52). Furthermore, prohormone convertases may convert membrane bound PAM protein into soluble PAM protein by cleavage within the flexible region (exons 25/26) connecting PAL with the TMD during the secretory pathway (Bousquet-Moore et al. 2010 . J Neurosci Res  88(12):2535-45). The PHM subunit may be cleaved from soluble or membrane bound PAM within the secretory pathway by prohormone convertases that address a double-basic cleavage-site in the exon 16 region. Furthermore, during endocytosis the full-length PAM protein may be also converted into a soluble form due to the action of alpha- and gamma secretases (Bousquet-Moore et al. 2010 . J Neurosci Res  88(12):2535-45). Membrane bound PAM from late endosome can be further secreted in form of exosomal vesicles. 
     PHM and PAL activities, as well as the activity of the full-length PAM were determined in several human tissues and body fluids. However, the separated PHM and PAL activities in soluble forms will also lead to formation of c-terminally alpha amidated products from c-terminally glycinated substrates when allowed to perform their separate reactions in the same compartment, body-fluid or in vitro experimental setup. How the transfer of the PHM hydroxylated product to the PAL takes place is not exactly understood to date. There is evidence that the hydroxylated product is released into solution and is not directly transferred from PHM to PAL (Yin et al. 2011 . PLoS One  6(12):e28679). Also not clear to date is the source of PAM in circulation. 
     The partial reaction of PHM is depicted in  FIG.  2   . PHM is a copper dependent monooxygenase responsible for stereo-specific hydroxylation of the c-terminal glycine at the alpha-carbon atom. During the hydroxylation reaction ascorbate is believed to be the naturally occurring reducing agent, while the oxygen in the newly formed hydroxyl group was shown to originate from molecular oxygen. The partial reaction of the PAL is depicted in  FIG.  2   . The catalytic action of PAL involves proton abstraction form the PHM-formed hydroxy-glycine by a protein-backbone derived base and a nucleophilic attack of hydroxyl-group oxygen to the divalent metal leading to a cleavage of glyoxylate and formation of a c-terminal amide. 
     Thus the term “amidating activity”, “alpha-amidating activity”, “peptidyl-glycine alpha-amidating activity” or “PAM activity” refers to the sequential enzymatic activities of PHM and PAL, independent of the present splice variant or mixtures of splice variants or post-translationally modified PAM enzymes or soluble, separated PHM or PAL activities or soluble PHM and membrane bound PAL or combinations of all mentioned forms leading to the formation of alpha amidated products of peptide or non-peptide character from glycinated substrates of peptide or non-peptide character. In other words, the term “amidating activity”, “alpha-amidating activity”, “peptidyl-glycine alpha-amidating activity” or “PAM activity” may be described as the sequential action of enzymatic activities located within amino acids 31 to 817 in the propeptide encoded by the human PAM cDNA, independent of present splice-variants or mixtures thereof. 
     PAM activity was analyzed in several human tissues and body fluids of healthy specimen or those suffering from several diseases. To summarize efforts that has been done in past: 
     Detection of PAM activities in human body-fluids mainly involves usage of radiolabeled synthetic tripeptides such as  125 I-D-TyrValGly,  125 I-N-acetyl-TyrValGly or comparably modified tripeptides and quantification of the amidated product due to gamma-scintillation (Kapuscinski et al. 1993 . Clinical Endocrinology  39(1): 51-58; Wand et al. 1985  Metabolism  34(11): 1044-52; Tsukamoto et al. 1995.  Internal Medicine  34(4): 229-32. Wand et al. 1987  Neurology  37: 1057-61. Wand et al. 1985  Neuroendocrinol  41: 482-89). Furthermore, Substance P-Gly or a truncated version Neuropeptide Y-Gly were utilized as substrates for PAM activity assays (Gether et al. 1991  Mol Cell Endocrinol  79 (1-3): 53-63; Hyyppä et al. 1990  Pain  43: 163-68; Jeng et al. 1990  Analytical Biochemistry  185(2): 213-19). 
     The presence of alpha-amidating activity in human circulation was initially proved by Wand et al. (Wand et al. 1985  Metabolism  34(11): 1044-52). They reported no sex differences but some variations of PAM activity in certain disease states: Plasma PAM activities were increased in hypothyroid adults as well as in patients with medullary thyroid carcinoma. The activity of PAM in tissues of medullary thyroid carcinoma, pheochromocytoma and pancreatic islet tumors were shown to be elevated suggesting increased formation of amidated peptides in endocrine tumor tissues (Gether et al. 1991  Mol Cell Endocrinol  79 (1-3): 53-63; Wand et al. 1985  Neuroendocrinol  41: 482-89). 
     Patients suffering from multiple endocrine neoplasia type 1 (MEN-1) and pernicious anemia showed a decreased plasma PAM activity in comparison to healthy control subjects (Kapuscinski et al. 1993 . Clin Endocrinol  39(1): 51-58). 
     The presence of amidating activity in human cerebrospinal fluid (CSF) was shown by Wand and colleagues (Wand et al. 1985  Neuroendocrinol  41: 482-89). In patients suffering from Alzheimer&#39;s disease (AD) plasma PAM activities were shown to be unaltered when compared to healthy controls, while CSF PAM activities were significantly decreased in comparison to activities from normal specimen (Wand et al. 1987  Neurology  37: 1057-61). In addition, in WO2015/103594 the presence of PAM-Protein in CSF detected by mass spectrometry of AD-patients was proposed to be reduced compared to healthy controls. Moreover, ADM-NH 2 , one of the amidated products of PAM, was shown to be reduced in patients with prevalent and incident Alzheimer&#39;s disease (WO2019/154900). However, no direct association of circulating PAM activities were reported to date being associated with prediction, diagnosis or progression of AD. 
     Amidating activity in CSF of patients with low back pain was analyzed using 1-12 Substance P-Gly (SP-Gly) as substrate (Hyyppä et al. 1990  Pain  43: 163-68). PAM activities of patients suffering from multiple sclerosis (MS) were shown to be increased in CSF, with a significant decrease in serum (Tsukamoto et al. 1995 . Internal Medicine  34(4): 229-32; WO2010/005387). An association between plasma activity of PAM and type-2-diabetes was described in (WO2014/118634). 
     Even though some findings were made regarding PAM activity in human body fluids and diseases or disease progression, there is no information on PAM concentrations in human body fluids, particularly in the circulation, measured with an immunoassay. As shown in the Examples, detection methods for the determination of the level of PAM (as the total amount or the activity of PAM) in a bodily fluid of a subject were established. With these assays it was shown that the level of PAM is decreased in a number of diseases as well as in patients who will develop a disease. Moreover, it was the surprising finding of the present application that the in vivo administration of recombinant PAM enzyme can be used to increase the PAM-level in the circulation, which results in an enhanced conversion of the PAM substrate adrenomedullin-glycine to mature adrenomedullin-amid. In conclusion, PAM may be used as therapy in a subject.

         a level of PAM and/or its isoforms and/or fragments thereof below a threshold and/or   a peptide-Gly/peptide-amide ratio above a threshold

In relation to said percentiles, the lower threshold that divides between healthy and diseased patients or healthy versus subjects at risk of getting a disease or subjects not at risk of getting an adverse event versus subjects at risk of getting an adverse event by detecting the PAM activity in plasma may be between 15 and 8 μg/(L*h) or below, more preferably between 13.5 and 8 μg/(L*h) or below, even more preferred between 10.5 and 8 μg/(L*h) or below, most preferred below 8 μg/(L*h); PAM activity in serum may be between 10 and 5 μg/(L*h) or below, more preferably between 8 and 5 μg/(L*h) or below, most preferred below 5 μg/(L*h) using a PAM activity assay. 
     In relation to said percentiles, the lower threshold that divides between healthy and diseased patients or healthy versus subjects at risk of getting a disease or subjects not at risk of getting an adverse event versus subjects at risk of getting an adverse event by detecting ADM-NH 2  is equal or below 15 pg/ml, preferably equal or below 10 pg/ml, preferably equal or below 5 pg/mL. 
     The threshold is pre-determined by measuring the ratio of ADM-Gly to ADM-NH 2  in healthy controls and calculating e.g., the according 75-percentile, more preferably the 90-percentile, even more preferably the 95-percentile. The upper boarder of the 75-percentile, more preferably the 90-percentile, even more preferably the 95-percentile, defines the threshold for healthy versus diseased patients or healthy versus subjects at risk of getting a disease or subjects not at risk of getting an adverse event versus subjects at risk of getting an adverse event, if the level of said diseased subjects or subjects at risk of getting a disease or adverse event is above a threshold. In relation to said percentiles, the upper threshold that divides between healthy and diseased patients or healthy versus subjects at risk of getting a disease or subjects not at risk of getting an adverse event versus subjects at risk of getting an adverse event by detecting the ration of ADM-Gly to ADM-NH 2 , wherein the ADM-Gly/ADM-NH 2  ratio is in a range between 1 and 10, preferably between 1.5 and 7.5, preferably between 2 and 5, most preferred the threshold is 2.5. 
     The predetermined value can vary among particular populations selected, depending on certain factors, such as gender, age, genetics, habits, ethnicity or alike. 
     The person skilled in the art knows how to determine thresholds from conducted previous studies. The person skilled in the art knows that a specific threshold value may depend on the cohort used for calculating a pre-determined threshold that can be later-on used in routine. The person skilled in the art knows that a specific threshold value may depend on the calibration used in the assay. The person skilled in the art knows that a specific threshold value may depend on the sensitivity and/or specificity that seems to be acceptable for the practitioner. 
     The sensitivity and specificity of a diagnostic test depends on more than just the analytical “quality” of the test, they also depend on the definition of what constitutes an abnormal result. In practice, Receiver Operating Characteristic curves (ROC curves), are typically calculated by plotting the value of a variable versus its relative frequency in “normal” (i.e., apparently healthy) and “disease” populations (i.e., patients suffering from an infection). Depending on the particular diagnostic question to be addressed, the reference group must not be necessarily “normal”, but it might be a group of patients suffering from another disease, from which the diseased group of interest shall be differentiated. For any particular marker, a distribution of marker levels for subjects with and without a disease will likely overlap. Under such conditions, a test does not absolutely distinguish normal from disease with 100% accuracy, and the area of overlap indicates where the test cannot distinguish normal from disease. A threshold is selected, above which (or below which, depending on how a marker changes with the disease) the test is considered to be abnormal and below which the test is considered to be normal. The area under the ROC curve is a measure of the probability that the perceived measurement will allow correct identification of a disease. ROC curves can be used even when test results do not necessarily give an accurate number. As long as one can rank results, one can create a ROC curve. For example, results of a test on “disease” samples might be ranked according to degree (e.g, 1=low, 2=normal, and 3=high). This ranking can be correlated to results in the “normal” population, and a ROC curve created. These methods are well known in the art (see, e.g., Hartley et al, 1982). Preferably, a threshold is selected to provide a ROC curve area of greater than about 0.5, more preferably greater than about 0.7. The term “about” in this context refers to +/−5% of a given measurement. 
     Once the threshold value is determined by using a previous study cohort and taking into consideration all the above-mentioned points the medical practitioner will use the pre-determined threshold for diagnosing or prognosing a disease and/or predicting a risk of getting a disease or an adverse event in a subject and will determine whether the subject has a value above or below said pre-determined threshold value in order to make an appropriate diagnosis, prognosis, prediction or monitoring. 
     The mentioned threshold values above might be different in other assays, if these have been calibrated differently from the assay system used in the present invention. Therefore, the mentioned threshold(s) shall apply for such differently calibrated assays accordingly, taking into account the differences in calibration. One possibility of quantifying the difference in calibration is a method comparison analysis (correlation) of the assay in question (e.g. PAM assay) with the respective biomarker assay used in the present invention by measuring the respective biomarker or it&#39;s activity (e.g. PAM) in samples using both methods. Another possibility is to determine with the assay in question, given this test has sufficient analytical sensitivity, the median biomarker level of a representative normal population, compare results with the median biomarker levels with another assay and recalculate the calibration based on the difference obtained by this comparison. With the calibration used in the present invention, samples from normal (healthy) subjects have been measured: the median plasma PAM activity was 18.4 μg/(L*h) (inter quartile range [IQR] 13.5-21.9 μg/(L*h)), the median serum PAM activity was 11.0 μg/(L*h) (inter quartile range [IQR] 8.1-13.1 μg/(L*h). In samples from normal (healthy) subjects have ADM-NH 2  been measured: median plasma bio-ADM (mature ADM-NH 2 ) was 13.7 pg/ml (inter quartile range [IQR] 9.6-18.7 pg/mL) (Weber et al. 2017 . JALM,  2(2): 222-233).

Particularly contemplated high-concentrations of therapeutic proteins (without taking into account the weight of chemical modifications such as PEGylation), are at least about 70, 80, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 175, 180, 185, 190, 195, 200, 250, 300, 350, 400, 450, or 500 mg/ml, and/or less than about 250, 300, 350, 400, 450 or 500 mg/ml. Exemplary high-concentrations of therapeutic proteins, such as enzymes, in the formulation may range from about 100 mg/ml to about 500 mg/ml. Preferably, the concentrations of the therapeutic protein according to the invention are in the range of about 100-300 mg/ml, more preferred in the range of 135-165 mg/ml, most preferred of about 150 mg/ml. A further most preferred concentration is about 100 mg/ml. In this context a concentration of “about” a given value, e.g. the upper or lower limit of a given concentration range, is to be understood as encompassing all concentration deviating up to +10% from this given value. 
     Chemical modifications may be employed for protecting PAM from degradation, extending in vivo half-life, providing prolonged drug release, augmenting drug efficacy, while reducing side effects, reducing administration frequency and lowering drug dosage. Other advantages include alleviation of pain associated with frequent injections and significant reduction in cost of treatment. Chemical modifications include covalent conjugation of polymers such as PEG (polyethyleneglycol), polysialic acid, hyperglycosylation and mannosylation (Patel et al. 2014.  Ther. Deliv.  5(3): 337-365). Alternative formulation approaches include colloidal carriers as protein delivery systems such as microparticles, nanoparticles, liposomes, carbon nanotubes and micelles (Patel et al. 2014 . Ther. Deliv.  5(3): 337-365). 
     In one embodiment of the invention said covalently conjugated polymer is selected from the group of branched or unbranched polyethyleneglycol (PEG), branched or unbranched polypropyleneglycol (PPG) hydroxyethyl starch (HES) or a derivative thereof, polysialic acids (PSAs) or a derivative thereof, or a glycine-rich homo-amino-acid polymer (HAP) (see WO2020254197 for reference). The polymer can be of any molecular weight. 
     In another aspect of the invention PAM may be administered via gene therapy. There are two major conventional methods of gene therapy, the first is to use viral capsids to encapsulate a DNA sequence of interest for introduction into mammalian tissue. Such viral capsids are generally termed viral vectors, and a variety of vectors have been used including HIV and adenoviruses. Such viral vectors are generally constructed so that they should not reproduce in-vivo, and usually contain a reverse transcriptase that results in splicing of the viral vector borne DNA into the host genome. The second major conventional method of gene therapy, DNA gene therapy, uses the much simpler method of injection of DNA into the patient. This introduces considerably less packaging material into the host, and DNA constructs are generally smaller. DNA is not incorporated into the host genome, but is instead maintained separately in circlets either inside the nucleus or at the nuclear wall inside the cell. These circlets may become associated with histones within the nucleus. 
     In a specific embodiment of the application, an assay is used for determining the level of PAM and/or its isoforms and/or fragments thereof, wherein such assay is a sandwich assay, preferably a fully automated assay. 
     In one embodiment of the application it may be a so-called POC-test (point-of-care) that is a test technology, which allows performing the test within less than 1 hour near the patient without the requirement of a fully automated assay system. One example for this technology is the immunochromatographic test technology. 
     In one embodiment of the application such an assay is a sandwich immunoassay using any kind of detection technology including but not restricted to enzyme label, chemiluminescence label, electrochemiluminescence label, preferably a fully automated assay. In one embodiment of the invention such an assay is an enzyme labeled sandwich assay. Examples of automated or fully automated assay comprise assays that may be used for one of the following systems: Roche Elecsys®, Abbott Architect®, Siemens Centauer®, Brahms Kryptor®, Biomerieux Vidas®, Alere Triage®, Ortho Clinical Diagnostics Vitros®. 
     In a specific embodiment of the application, at least one of said two binders is labeled in order to be detected. 
     The preferred detection methods comprise immunoassays in various formats such as for instance radioimmunoassay (RIA), homogeneous enzyme-multiplied immunoassays (EMIT), chemiluminescence- and fluorescence-immunoassays, Enzyme-linked immunoassays (ELISA), Luminex-based bead arrays, protein microarray assays, and rapid test formats such as for instance immunochromatographic strip tests. 
     In a preferred embodiment, said label is selected from the group comprising chemiluminescent label, enzyme label, fluorescence label, radioiodine label. 
     The assays can be homogenous or heterogeneous assays, competitive and non-competitive assays. In one embodiment, the assay is in the form of a sandwich assay, which is a non-competitive immunoassay, wherein the molecule to be detected and/or quantified is bound to a first antibody and to a second antibody. The first antibody may be bound to a solid phase, e.g. a bead, a surface of a well or other container, a chip or a strip, and the second antibody is an antibody which is labeled, e.g. with a dye, with a radioisotope, or a reactive or catalytically active moiety. The amount of labeled antibody bound to the analyte is then measured by an appropriate method. The general composition and procedures involved with “sandwich assays” are well-established and known to the skilled person ( The Immunoassay Handbook , Ed. David Wild, Elsevier LTD, Oxford; 3rd ed. (May 2005); Hultschig et al. 2006  Curr Opin Chem Biol.  10 (1):4-10). 
     In another embodiment the assay comprises two capture molecules, preferably antibodies which are both present as dispersions in a liquid reaction mixture, wherein a first labelling component is attached to the first capture molecule, wherein said first labelling component is part of a labelling system based on fluorescence- or chemiluminescence-quenching or amplification, and a second labelling component of said marking system is attached to the second capture molecule, so that upon binding of both capture molecules to the analyte a measurable signal is generated that allows for the detection of the formed sandwich complexes in the solution comprising the sample. 
     In another embodiment, said labeling system comprises rare earth cryptates or rare earth chelates in combination with fluorescence dye or chemiluminescence dye, in particular a dye of the cyanine type. In the context of the present invention, fluorescence based assays comprise the use of dyes, which may for instance be selected from the group comprising FAM (5- or 6-carboxyfluorescein), VIC, NED, fluorescein, fluorescein-isothiocyanate (FITC), IRD-700/800, Cyanine dyes, such as CY3, CY5, CY3.5, CY5.5, Cy7, xanthen, 6-Carboxy-2′,4′,7′,4,7-hexachlorofluorescein (HEX), TET, 6-Carboxy-4′,5′-dichloro-2′,7′-dimethodyfluorescein (JOE), N,N,N′,N′-Tetramethyl-6-carboxyrhodamine (TAMRA), 
     6-Carboxy-X-rhodamine (ROX), 5-Carboxyrhodamine-6G (R6G5), 6-carboxyrhodamine-6G (RG6), Rhodamine, Rhodamine Green, Rhodamine Red, Rhodamine 110, BODIPY dyes, such as BODIPY TMR, Oregon Green, coumarines such as umbelliferone, benzimides, such as Hoechst 33258; Phenanthridines, such as Texas Red, Yakima Yellow, Alexa Fluor, PET, ethidiumbromide, acridinium dyes, carbazol dyes, Phenoxazine dyes, porphyrine dyes, polymethine dyes, and the like. 
     In the context of the application, chemiluminescence based assays comprise the use of dyes, based on the physical principles described for chemiluminescent materials in (Kirk-Othmer,  Encyclopedia of chemical technology,  4 th ed.  1993. John Wiley &amp; Sons, Vol. 15: 518-562, incorporated herein by reference, including citations on pages 551-562). Preferred chemiluminescent dyes are acridinium esters. 
     As mentioned herein, an “assay” or “diagnostic assay” can be of any type applied in the field of diagnostics. Such an assay may be based on the binding of an analyte to be detected to one or more capture probes with a certain affinity. Binders that may be used for determining the level of PAM and/or its isoforms and/or fragments thereof exhibit an affinity constant to PAM and/or its isoforms and/or fragments thereof of at least 10 7  M −1 , preferred 108 M −1 , preferred affinity constant is greater than 10 9  M −1 , most preferred greater than 10 10  M −1 . A person skilled in the art knows that it may be considered to compensate lower affinity by applying a higher dose of compounds and this measure would not lead out-of-the-scope of the invention. 
     In the context of the present application, “binder molecules” are molecules which may be used to bind target molecules or molecules of interest, i.e. analytes (i.e. in the context of the present invention PAM and its isoforms and fragments thereof), from a sample. Binder molecules have thus to be shaped adequately, both spatially and in terms of surface features, such as surface charge, hydrophobicity, hydrophilicity, presence or absence of lewis donors and/or acceptors, to specifically bind the target molecules or molecules of interest. Hereby, the binding may for instance be mediated by ionic, van-der-Waals, pi-pi, sigma-pi, hydrophobic or hydrogen bond interactions or a combination of two or more of the aforementioned interactions between the capture molecules and the target molecules or molecules of interest. In the context of the present invention, binder molecules may for instance be selected from the group comprising a nucleic acid molecule, a carbohydrate molecule, a PNA molecule, a protein, an antibody, a peptide or a glycoprotein. Preferably, the binder molecules are antibodies, including fragments thereof with sufficient affinity to a target or molecule of interest, and including recombinant antibodies or recombinant antibody fragments, as well as chemically and/or biochemically modified derivatives of said antibodies or fragments derived from the variant chain. 
     In a specific embodiment said binder may be selected from the group of antibody, antibody fragment or non-IgG scaffold. 
     Chemiluminescent label may be acridinium ester label, steroid labels involving isoluminol labels and the like. 
     Enzyme labels may be lactate dehydrogenase (LDH), creatine kinase (CPK), alkaline phosphatase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), acid phosphatase, glucose-6-phosphate dehydrogenase and so on. 
     In one embodiment of the application at least one of said two binders is bound to a solid phase as magnetic particles, and polystyrene surfaces. 
     Subject matter of the application is a method for determining the level of PAM and/or isoforms and/or fragments thereof in a bodily fluid sample using an assay, wherein said assay is comprising two binders that bind to two different epitopes of PAM, wherein the two binders are directed to an epitope of at least 5 amino acids, preferably at least 4 amino acids in length. 
     An epitope, also known as antigenic determinant, is the part of an antigen (e.g. peptide or protein) that is recognized by the immune system, specifically by antibodies. For example, the epitope is the specific piece of the antigen to which an antibody binds. The part of an antibody that binds to the epitope is called a paratope. The epitopes of protein antigens are divided into two categories: conformational epitopes and linear epitopes, based on their structure and interaction with the paratope. 
     A linear or a sequential epitope is an epitope that is recognized by antibodies by its linear sequence of amino acids, or primary structure and is formed by the 3-D conformation adopted by the interaction of contiguous amino acid residues. Conformational and linear epitopes interact with the paratope based on the 3-D conformation adopted by the epitope, which is determined by the surface features of the involved epitope residues and the shape or tertiary structure of other segments of the antigen. A conformational epitope is formed by the 3-D conformation adopted by the interaction of discontiguous amino acid residues. 
     In one embodiment of the application linear epitopes are related to following sequences of immunization peptides of PAM: peptide 1 (SEQ ID No. 11), peptide 2 (SEQ ID No. 12), peptide (SEQ ID No. 13), peptide 4 (SEQ ID No. 14), peptide 5 (SEQ ID No. 15), peptide 6 (SEQ ID No. 16), peptide 7 (SEQ ID No. 17), peptide 8 (SEQ ID No. 18), peptide 9 (SEQ ID No. 19), peptide 10 (SEQ ID No. 20), peptide 11 (SEQ ID No. 21), peptide 12 (SEQ ID No. 22), peptide 13 (SEQ ID No. 23) peptide 14 (SEQ ID No. 24). 
     In one embodiment of the application, linear and/or conformational epitopes are related to the following sequences of PAM: SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 3, SEQ ID No. 4, SEQ ID No. 5, SEQ ID No. 6, SEQ ID No. 7, SEQ ID No. 8, SEQ ID No. 10. 
     Said epitope may comprise at least 6 amino acids, preferably at least 5 amino acids, most preferred at least 4 amino acids. 
     In one embodiment of the application said first and second binder binds to an epitope comprised within the following sequences of PAM: SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 3, SEQ ID No. 4, SEQ ID No. 5 and SEQ ID No. 6. 
     In one embodiment of the application said first and second binder binds to an epitope comprised within the PAL subunit of PAM (SEQ ID No. 8). 
     In one embodiment of the application said first and second binder binds to an epitope comprised within the PHM subunit of PAM (SEQ ID No. 7). 
     In one specific embodiment of the application said first binder binds to an epitope comprised within the PAL subunit of PAM (SEQ ID No. 8) and said second binder binds to an epitope comprised within the PHM subunit of PAM (SEQ ID No. 7). 
     In one specific embodiment of the application said first and second binder binds to an epitope comprised within the following sequences of PAM: peptide 1 (SEQ ID No. 11), peptide 2 (SEQ ID No. 12), peptide (SEQ ID No. 13), peptide 4 (SEQ ID No. 14), peptide 5 (SEQ ID No. 15), peptide 6 (SEQ ID No. 16), peptide 7 (SEQ ID No. 17), peptide 8 (SEQ ID No. 18), peptide 9 (SEQ ID No. 19), peptide 10 (SEQ ID No. 20), peptide 11 (SEQ ID No. 21), peptide 12 (SEQ ID No. 22), peptide 13 (SEQ ID No. 23) peptide 14 (SEQ ID No. 24) and recombinant PAM (SEQ ID No. 10). 
     Use of at least two binders for the determination of the level of PAM and/or its isoforms and/or fragments thereof, wherein said at least one binder is directed to an epitope comprised within the following sequences of PAM: peptide 1 (SEQ ID No. 11), peptide 2 (SEQ ID No. 12), peptide (SEQ ID No. 13), peptide 4 (SEQ ID No. 14), peptide 5 (SEQ ID No. 15), peptide 6 (SEQ ID No. 16), peptide 7 (SEQ ID No. 17), peptide 8 (SEQ ID No. 18), peptide 9 (SEQ ID No. 19), peptide 10 (SEQ ID No. 20), peptide 11 (SEQ ID No. 21), peptide 12 (SEQ ID No. 22), peptide 13 (SEQ ID No. 23) peptide 14 (SEQ ID No. 24) and recombinant PAM (SEQ ID No. 10). 
     Subject of the present application is a method for determining the activity of PAM and/or isoforms and/or fragments thereof in a bodily fluid sample of a subject comprising the steps
         Contacting said sample with a capture-binder that binds specifically to active full-length PAM, its isoforms and/or active fragments thereof,   Separating PAM bound to said capture-binder   Adding a substrate of PAM to said separated PAM   Quantifying PAM activity by measuring the conversion of the substrate of PAM.       

     In a specific embodiment of the present application said method is an enzyme capture assay (ECA, see e.g. U.S. Pat. Nos. 5,612,186A, 5,601,986A). 
     In a specific embodiment of said method for determining PAM activity in a bodily fluid sample of a subject said separation step is a washing step that removes ingredients of the sample that are not bound to said capture-binder from the captured PAM and/or its isoforms and/or fragments thereof. That separation step can be any other step that separates PAM bound to said capture-binder from the ingredients of said bodily fluid sample. 
     One embodiment of the present application involves a chemical assay for PAM. The assay uses a peptide substrate which reacts with PAM and/or its isoforms and/or fragments thereof to form a detectable reaction product. Alternatively, the rate of the reaction of the substrate can be monitored to determine the level of PAM and/or its isoforms and/or fragments thereof in a test sample. 
     Assays embodying such reagents and reactions can be performed in any suitable reaction vessel, for example, a test tube or well of a microtiter plate. Alternatively, assay devices may be developed in disposable form such as dipstick or test strip device formats which are well known to those skilled-in-the-art and which provide ease of manufacture and use. Such disposable assay devices may be packaged in the form of kits containing all necessary materials, reagents and instructions for use. 
     In an alternative assay embodiment, the rate at which the reaction occurs may be detected as an indication of the level of PAM and/or its isoforms and/or fragments thereof present in the test sample. For example, the rate at which the substrate is reacted may be used to indicate the level of PAM and/or its isoforms and/or fragments thereof present in the test sample. Alternatively, the rate at which the reaction product is formed may be used to indicate the level of PAM and/or its isoforms and/or fragments thereof present in the test sample. 
     In yet another embodiment, a capture or binding assay may be performed to determine the activity of PAM and/or its isoforms and/or fragments thereof. For example, an antibody reactive with PAM protein, but which does not interfere with its enzymatic activity, may be immobilized upon a solid phase. The test sample is passed over the immobile antibody, and PAM and/or its isoforms and/or fragments thereof, if present, binds to the antibody and is itself immobilized for detection. A substrate may then be added, and the reaction product may be detected to indicate the level of PAM and/or its isoforms and/or fragments thereof in the test sample. For the purposes of the present description, the term “solid phase” may be used to include any material or vessel in which or on which the assay may be performed and includes, but is not limited to, porous materials, nonporous materials, test tubes, wells, slides, etc. 
     In a specific embodiment of said method for the diagnosis or prognosis of a disease in a subject and/or predicting a risk of getting a disease or adverse event in a subject and/or monitoring a disease or adverse event in a subject by determining the level of peptidylglycine alpha-amidating monooxygenase (PAM) and/or its isoforms and/or fragments thereof in a sample of bodily fluid of said subject said capture binder is immobilized on a surface. For the determination of PAM activity, a binder reactive with PAM and/or its isoforms and/or fragments thereof, but which does not interfere with enzymatic activity by more than 50%, preferably less than 40%, preferably less than 30%, may be immobilized upon a solid phase. To prevent inhibition of PAM the capture-binder should not bind PAM in the area around the active center and substrate binding region. 
     In a specific embodiment of said method for determining the level of PAM and/or its isoforms and/or fragments thereof in a bodily fluid sample of a subject said binder may be selected from the group of antibodies, antibody fragments, non-Ig scaffolds or aptamers. 
     Another subject of the present application is a method for determining the activity of PAM and/or isoforms and/or fragments thereof in a bodily fluid sample of a subject comprising the steps

     Another subject of the present application is a method for determining PAM activity in a bodily fluid sample of a subject comprising the steps
         contacting said sample with the substrate ADM-Gly of PAM for an interval of time at t=0 min and t=n+1 min   detecting the reaction product ADM-NH 2  of PAM in said sample at t=0 min and t=n+1 min using an immunoassay, and   quantifying the activity of PAM by calculating the difference of the reaction product ADM-NH 2  between t=0 min and t=n+1 min.       

     The term “t=n+1 min” is a time interval, wherein n is defined as ≥0 min.

     EXAMPLES 
     Example 1—Production of Recombinant PAM 
     PAM cDNA was synthesized according to Uniprot Accession No. P19021 encoding amino acids 21-834 of the PAM protein involving codon optimization for expression in mammalian cells. The signal sequence of PAM was replaced with human serum albumin signal sequence (MKWVTFISLLFLFSSAYSFR [SEQ ID No. 9]). At the C-terminus of PAM a hexa-histidine tag was added linked via a GS linker to PAM. The sequence of recombinant PAM (amino acids 21-834 of PAM without signal sequence and hexa-histidine tag) is shown in SEQ ID No. 10. The cDNA was cloned into an expression vector (plasmid DNA) using a 5′-NotI and a 3′ HindIII restriction site. The expression vector harboring the cDNA for PAM expression was replicated in- and prepared from  E. coli . as a low-endotoxin preparation. 
     HEK-INV cells were transfected with the expression vector using INVect transfection reagents in serum free suspension culture. The transfection rate was controlled via co-transfection with a GFP—(green fluorescent protein) containing expression vector. Cultivation of cells was carried out in presence of valproic acid and Penicillin-Streptomycin at 37° C. and 5% CO 2 . Cells were harvested via centrifugation when viability reached &lt;60% (&gt;2000 g, 30-45 min, 2-8° C.). Cell culture supernatant (CCS) was washed 5 times with 100 mM Tris/HCl, pH 8.0 via tangential flow filtration (TFF, 30 kDa cut-off). 
     Purification of recombinant PAM included application of buffer exchanged CCS on a Q-sepharose fast flow resin (GE Healthcare) with a NaCl gradient (up to 2 M) elution. Amidating activity containing fractions were pooled and applied onto a Superdex 200 pg (GE Healthcare) size exclusion chromatography column with a 100 mM Tris/HCl, 200 mM NaCl, pH8.0 elution buffer. Amidating activity containing fractions were pooled, dialyzed against 100 mM Tris HCl, 200 mM NaCl, pH 8.0, sterile filtered (0.2 μm). Endotoxin load was determined by Charles River PTS Endosafe system and was below 5 EU/mL. 
     Example 2—Production of Antibodies 
     Anti-PAM antibodies according to the present invention may be synthesised as follows: 
     PAM peptides for immunization were synthesized, see Table 1, (Peptides &amp; Elephants, Hennigsdorf, Germany) with an additional C-terminal cysteine (if no cysteine is present within the selected PAM-sequence) residue for conjugation of the peptides to Bovine Serum Albumin (BSA). The peptides were covalently linked to BSA by using Sulfolink-coupling gel (Perbio-science, Bonn, Germany). The coupling procedure was performed according to the manual of Perbio. Recombinant PAM was produced by InVivo Biotech Services, Hennigsdorf, as described in example 1.

     Balb/c mice were intraperitoneally (i.p.) injected with 100 μg recombinant PAM or 100 μg PAM-peptide-BSA-conjugates at day 0 (emulsified in TiterMax Gold Adjuvant), 100 μg and 100 μg at day 14 (emulsified in complete Freund&#39;s adjuvant) and 50 μg and 50 μg at day 21 and 28 (in incomplete Freund&#39;s adjuvant). The animal received an intravenous (i.v.) injection of 50 μg recombinant PAM at day 40 or 50 μg PAM-peptide-BSA-conjugates dissolved in saline at day 45. Three days later the mice were sacrificed and the immune cell fusion was performed. 
     Splenocytes from the immunized mice and cells of the myeloma cell line SP2/0 were fused with 1 ml 50% polyethylene glycol for 30 s at 37° C. After washing, the cells were seeded in 96-well cell culture plates. Hybrid clones were selected by growing in HAT medium (RPMI 1640 culture medium supplemented with 20% fetal calf serum and HAT-Supplement). After one week, the HAT medium was replaced with HT Medium for three passages followed by returning to the normal cell culture medium. 
     The cell culture supernatants were primarily screened for recombinant PAM binding IgG antibodies two weeks after fusion. Therefore, recombinant PAM (SEQ ID No. 10) was immobilized in 96-well plates (100 ng/well) and incubated with 50 μl cell culture supernatant per well for 2 hours at room temperature. After washing of the plate, 50 μl/well POD-rabbit anti mouse IgG was added and incubated for 1 h at RT. 
     After a next washing step, 50 μl of a chromogen solution (3.7 mM o-phenylene-diamine in citrate/hydrogen phosphate buffer, 0.012% H 2 O 2 ) were added to each well, incubated for 15 minutes at RT and the chromogenic reaction stopped by the addition of 50 μl 4N sulfuric acid. Absorption was detected at 490 mm. 
     The positive tested microcultures were transferred into 24-well plates for propagation. After retesting the selected cultures were cloned and re-cloned using the limiting-dilution technique and the isotypes were determined. 
     Antibodies raised against recombinant human PAM or PAM-peptides were produced via standard antibody production methods (Marx et al. 1997) and purified via Protein A. The antibody purities were ≥90% based on SDS gel electrophoresis analysis. 
     Example 3—PAM Activity Assay 
     Human serum or Li-Heparin plasma from self-reported healthy volunteers was used as source of human native PAM. Each sample (20 μl) was diluted two-fold in 100 mM Tris-HCl in duplicate. The amidation reaction was initiated by addition of 160 μl of PAM-reaction buffer (100 mM Tris-HCl, pH 7.5, 6.25 μM CuSO 4 , 2.5 mM L-ascorbate, 125 μg/mL catalase, 62.5 μM amastatin, 250 μM leupeptin, 36 ng/mL synthetic ADM-Gly and 375 μg/mL NT-ADM antibody). Afterwards, 100 μl of each individual reaction of duplicated samples were combined and transferred into 20 μl of 200 mM EDTA to terminate the amidation reaction and to generate t=0 minutes reaction time-point followed by incubation at 37° C. for 40 minutes. Afterwards the non-terminated reactions were stopped with 10 μl of 200 mM EDTA. To determine the PAM activity, bio-ADM as reaction product was quantified in each sample using the Sphingotest® bio-ADM immunoassay (Weber et al. 2017). The amidation assay was calibrated using a 6-point calibration curve generated with human recombinant PAM of known activity. Samples and calibrators were treated in the same manner. Relative light units (RLU t40 min-t0 min) determined via Sphingotest® bio-ADM immunoassay for each sample were fitted against the RLU (t40 min-t0 min) of the calibrator to determine the PAM activity in the samples. PAM activity is described as “adrenomedullin maturation activity” (AMA) in μg bio-ADM formed per hour and L of sample. 
     A typical PAM calibration curve is shown in  FIG.  3   . The distribution of AMA in Li-Heparin samples from n=120 self-reported healthy volunteers are shown in  FIG.  4   . The median [IQR] of Li-Heparin AMA was 18.4 μg/(L*h) [13.5-21.9]. The 10 th  and 90 th  percentile was 10.5 and 24.2 μg/(L*h), respectively. The 2.5 th , 97.5 th  and 99 th  percentile was 8.1, 31.6 and 40.8 μg/(L*h). In addition, matched serum samples from n=20 subjects were measured and revealed a highly significant correlation (r=0.89; p&lt;0.0001) ( FIG.  5   ), although AMA values in serum were approximately 40% lower when compared to Li-Heparin. 
     Example 4—PAM Immunoassays 
     Antibodies against recombinant PAM (SEQ ID No. 10) and PAM peptides (SEQ ID No. 11 to 24) were raised as described in example 1. 
     The technology used was a sandwich luminescence immunoassay, based on Akridinium ester labelling. 
     4.1. Labelled Compound (Tracer) 
     Purified antibodies (0.2 g/L) were labelled by incubation in 10% labelling buffer (500 mmol/L sodium phosphate, pH 8.0) with 1:5 mol/L ratio of MACN-acridinium-NHS-ester (1 g/L, InVent GmbH) for 20 min at 22° C. After adding 5% 1 mol/L Tris-HCl, pH 8.0, for 10 min, the respective antibody was separated from free label via CentriPure P10 columns (emp Biotech GmbH). The purified labelled antibody was diluted in 300 mmol/l potassium phosphate, 100 mmol/l NaCl, 10 mmol/l Na-EDTA, 5 g/l Bovine Serum Albumin (pH 7.0). The final concentration was approximately 20 ng of labelled antibody per 150 μL. 
     4.2. Solid Phase 
     White polystyrene microtiter plates (Greiner Bio-One International AG) were coated (18 h at 20° C.) with the respective antibody (2 μg/0.2 mL per well 50 mmol/L Tris-HCl, 100 mmol/L NaCl, pH 7.8). After blocking with 30 g/L Karion, 5 g/L BSA (protease free), 6.5 mmol/L monopotassium phosphate, 3.5 mmol/L sodium dihydrogen phosphate (pH 6.5), the plates were vacuum-dried. 
     4.3 Calibration 
     The assay was calibrated, using dilutions of recombinant PAM as described in Example 1. The typical concentration range was within of 5-5,000 ng/mL. 
     4.4. PAM Immunoassays: 
     4.4.1. PAM-LIA 
     One-Step version: 50 μL of samples/calibrators were pipetted into pre-coated microtiter plates. After adding 200 μL of labelled antibody in buffer (300 mmol/L potassium phosphate, 100 mmol/L NaCl, 10 mmol/L Na-EDTA, 50 μmol/L amastatin, 100 μmol/L leupeptin, 0.1% bovine IgG, 0.02% mouse IgG, 0.5% BSA, pH 7.0), the microtiter plates were incubated for 20 h at 2-8° C. under agitation at 600 rpm. Unbound tracer was removed by washing 5 times (each 350 μL per well) with washing solution (20 mmol/L PBS, 1 g/L Triton X-100, pH 7.4). Wellbound chemiluminescence was measured for 1 s per well by using the Centro LB 960 microtiter plate luminescence reader (Berthold Technologies). 
     Two-Step version: 50 μL of samples/calibrators were pipetted into pre-coated microtiter plates. After adding 200 μL of buffer (as described in one-step version), the microtiter plates were incubated for 15-20 h at 2-8° C. under agitation at 600 rpm. Unbound sample was removed by washing 4 times (each 350 μL per well) with washing solution with subsequent addition of 200 μl of tracer material and incubation of microtiter plates at room temperature for 2 h. Unbound tracer was removed by washing 4 times (each 350 μL per well) with washing solution. Wellbound chemiluminescence was measured for 1 s per well by using the Centro LB 960 microtiter plate luminescence reader (Berthold Technologies). 
     Results: Antibodies bound to the solid phase and labelled antibodies directed to the different PAM immunization peptides as well as full-length (recombinant) PAM (see example 2) were tested with recombinant PAM as well as blood samples. Exemplary standard curves for different antibody combinations are shown in  FIG.  6    (A-L).  FIGS.  6    (A-J) with recombinant PAM as calibration material: (A) solid phase: antibody directed to peptide 10 (SEQ ID No. 20), tracer: antibody directed to peptide 9 (SEQ ID No. 19); (B) solid phase: antibody directed to peptide 10 (SEQ ID No. 20), tracer: antibody directed to peptide 10 (SEQ ID No. 20); (C) solid phase: antibody directed to peptide 9 (SEQ ID No. 19), tracer: antibody directed to peptide 10 (SEQ ID No. 20); (D) solid phase: antibody directed to recombinant PAM (SEQ ID No. 10), tracer: antibody directed to recombinant PAM (SEQ ID No. 10); (E) solid phase: antibody directed to peptide 10 (SEQ ID No. 20), tracer: antibody directed to recombinant PAM (SEQ ID No. 10); (F) solid phase: antibody directed to peptide 13 (SEQ ID No. 23), tracer: antibody directed to peptide 10 (SEQ ID No. 20); (G) solid phase: antibody directed to peptide 14 (SEQ ID No. 24), tracer: antibody directed to peptide 13 (SEQ ID No. 23); (H) solid phase: antibody directed to recombinant PAM (SEQ ID No. 10), tracer: antibody directed to peptide 13 (SEQ ID No. 23); (I) solid phase: antibody directed to peptide 13 (SEQ ID No. 23), tracer: antibody directed to peptide 9 (SEQ ID No. 19); (J) solid phase: antibody directed to peptide 10 (SEQ ID No. 20), tracer: antibody directed to peptide 13 (SEQ ID No. 23).  FIGS.  6    (K and L) with native PAM (EDTA-Plasma) as calibration material: (K) solid phase: antibody directed to peptide 14 (SEQ ID No. 24), tracer: antibody directed to peptide 13 (SEQ ID No. 23); (L) solid phase: antibody directed to peptide 10 (SEQ ID No. 20), tracer: antibody directed to peptide 13 (SEQ ID No. 23). With all antibody combinations PAM was also detectable in human plasma and serum samples. 
     4.4.2. Enzyme Capture Assay (ECA) for the Detection of PAM Activity 
     Enzyme capture assays were established to detect the activity of PAM. 50 μL of samples/calibrators were pipetted into pre-coated microtiter plates (as described in 4.2). After adding 200 μL of buffer (300 mmol/L potassium phosphate, 100 mmol/L NaCl, 50 μmol/L amastatin, 100 μmol/L leupeptin, 0.1% bovine IgG, 0.02% mouse IgG, 0.5% BSA, pH 7.0) the microtiter plates were incubated for 1 h at room temperature under agitation at 600 rpm. Unbound sample was removed by washing 4 times (each 350 μL per well) with washing solution with subsequent addition of 200 μl reaction buffer per well and incubation at 37° C. Reaction buffer including all components and final concentrations were as described in Example 3, with the exceptions that 100 pg/mL NT-ADM-antibody and 288 ng/mL ADM-Gly were used. Reaction was terminated at several time-points by transferring 10 μl of each individual reaction into 190 μl of EDTA containing buffer (300 mmol/L potassium phosphate, 100 mmol/L NaCl, 10 mmol/L Na-EDTA, 50 μmol/L amastatin, 100 μmol/L leupeptin, 0.1% bovine IgG, 0.02% mouse IgG, 0.5% BSA, pH 7.0). Terminated reactions were applied onto the Sphingotest® bio-ADM immunoassay for quantification of produced bio-ADM. A typical standard curve using an antibody directed to PAM immunization peptide 10 (SEQ ID No. 20) as solid phase is shown in  FIG.  6    M. 
       FIG.  6    N shows a typical standard curve using an antibody directed to full-length recombinant PAM (SEQ ID No. 10). Further antibodies directed to peptide 7 (SEQ ID No. 17), peptide 8 (SEQ ID No. 18), peptide 9 (SEQ ID No. 19), peptide 13 (SEQ ID No. 23) and peptide 14 (SEQ ID No. 24) were used as solid phase for the enzyme capture assay and a sample (250 μl) of recombinant PAM or heparin plasma was measured for PAM activity ( FIG.  6    O). These results show, that the antibodies can be used to detect PAM activity in human samples using the ECA technique. PAM was also detectable in plasma and serum samples. 
     In a further step, PAM activity (as described in example 3) and PAM concentration using a PAM-LIA (solid phase antibody directed against full-length PAM, tracer antibody directed against peptide 13 [SEQ ID No. 23]) were determined in heparin samples from healthy volunteers (n=26). PAM activity and PAM concentration correlated significantly as shown in  FIG.  6    P (Spearman r=0.49, p=0.0109). 
     Example 5—ADM-Gly Immunoassay 
     ADM-Gly was quantified as based on Weber et al. (Weber et al. 2017 . JALM  2(2): 222-233) for bioactive ADM with the following modifications: the tracer-antibody used for ADM-Gly detection, labelled with MACN-acridinium-NHS, was directed to the C-terminal glycine of ADM-Gly. The assay was calibrated with synthetic ADM-Gly. The limit of detection (LOD) was 10 pg/mL of ADM-Gly. Cross-reactivity of antibody directed to the C-terminal glycine of ADM with bio-ADM was in the range between 6 and 50% in a concentration dependent manner. All determined ADM-Gly concentrations were corrected for cross-reactivity as follows: For each ADM-Gly quantification additional quantification of bio-ADM in corresponding samples was performed using the Sphingotest® bio-ADM immunoassay. The corresponding bio-ADM values were used to determine the signal (RLU) generated with the antibody directed to C-terminal glycine of ADM on a bio-ADM calibration curve. The determined signal (RLU) was used to calculate the false-positive ADM-Gly concentration (pg/mL) using the ADM-Gly calibration curve. This concentration was subtracted from the initially determined ADM-Gly concentration. A typical standard curve is shown in  FIG.  7   . 
     Example 6—Prediction of Diseases in Healthy Subjects 
     The Malmö Preventive Project (MPP) was funded in the mid-1970s to explore CV risk factors in general population, and enrolled 33,346 individuals living in Malmö (Fedorowski et al. 2010 . Eur Heart J  31: 85-91). Between 2002 and 2006, a total of 18,240 original participants responded to the invitation (participation rate, 70.5%) and were screened including a comprehensive physical examination and collection of blood samples (Fava et al. 2013 . Hypertension  2013; 61: 319-26). The re-examination in MPP is in the present study regarded as the baseline. Subjects with prior CVD at baseline were excluded. An informed consent was obtained from all participants and the Ethical Committee of Lund University, Lund, Sweden, approved the study protocol. 
     A commercial fully automated homogeneous time-resolved fluoro-immunoassay was used to measure MR-proADM in plasma (BRAHMS MR-proADM KRYPTOR; BRAHMS GmbH, Hennigsdorf, Germany) (Caruhel et al. 2009 . Clin Biochem.  42 (7-8):725-8). 
     Bio-ADM was measured as described by Weber et al. 2017 (Weber et al. 2017 . JAMA  2(2): 222-233). AMA was determined in 4942 serum samples from MPP as described in example 3. Each sample was measured in duplicate. Samples, controls and calibrators were treated in the same manner. Baseline clinical characteristics of AMA after stratification to Quartiles is shown in table 2.

     Statistical analysis: Values are expressed as means and standard deviations, medians and interquartile ranges (IQR), or counts and percentages as appropriate. Group comparisons of continuous variables were performed using the Kruskal-Wallis test. Biomarker data were log-transformed. Cox proportional-hazards regression was used to analyze the effect of risk factors on survival in uni- and multivariable analyses. The assumptions of proportional hazard were tested for all variables. For continuous variables, hazard ratios (HR) were standardized to describe the HR for a biomarker change of one IQR. 95% confidence intervals (CI) for risk factors and significance levels for chi-square (Wald test) are given. The predictive value of each model was assessed by the model likelihood ratio chi-square statistic. The concordance index (C index) is given as an effect measure. It is equivalent to the concept of AUC adopted for binary outcome. For multivariable models, a bootstrap corrected version of the C index is given. Survival curves plotted by the Kaplan-Meier method were used for illustrative purposes. To test for independence of PAM from clinical variables we used the likelihood ratio chi-square test for nested models. All statistical tests were 2-tailed and a two-sided p-value of 0.05 was considered for significance. 
     6.2. Prediction of Alzheimer&#39;s Disease 
     3954 samples with information about dementia diagnosis were selected (n=174 with incident AD). Information about dementia diagnoses was requested from the Swedish National Patient Register (SNPR). The diagnoses in the register were collected according to different revisions of the International Classification of Diseases (ICD) codes 290, 293 (ICD-8), 290, 331 (ICD-9) or F00, FO1, F03, G30 (ICD-10). Since 1987, SNPR includes all in-patient care in Sweden and, in addition, contains data on outpatient visits including day surgery and psychiatric care from both private and public caregivers recorded after 2000. All-cause dementia was diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III revised edition, whilst the DSM-IV criteria were applied for the Alzheimer&#39;s disease and vascular dementia diagnoses. Diagnoses were validated by a thorough review of medical records as well as neuroimaging data when available. A research physician assigned the final diagnosis for each patient and a geriatrician specialized in cognitive disorders was consulted in unresolved cases. The PAM activity (AMA) was determined as described in example 3. AMA in the MPP cohort is shown in  FIG.  8   : AMA in patients developing AD over time (incident AD, n=174) are significantly lower compared to the non-AD group (p=0.01). 
     Reduced serum AMA strongly predicts Alzheimer&#39;s disease with a Hazard Ratio (HR) of 0.74 (CI 0.6-0.88; p&lt;0.001) and a HR of 0.72 (CI 0.6-0.85) when adjusted for age (table 3).  FIG.  9    shows a Kaplan-Meier Plot for the prediction of Alzheimer&#39;s disease using AMA (prevalent AD cases were excluded from the analysis). The lowest tertile is associated with the highest risk of getting AD. 
     Furthermore, AMA as a predictor of AD was independent from bio-ADM concentrations. Both markers contribute to AD prediction. While the C-Index for AMA alone is 0.571 (CI 0.525-0.616; Chi 2  10.97) the C-index for both combined markers, i.e., AMA and bio-ADM is 0.595 (Chi 2  18.96; p&lt;0.0001). Moreover, AMA in combination with bio-ADM and MR-proADM concentrations further improve the prediction of incident Alzheimer. While MR-proADM alone had no predictive value for AD, the combination of AMA, bio-ADM and MR-proADM showed a C-index of 0.622 (Chi 2  26.73; p=0.00001).

     6.3. Prediction of Colorectal Cancer (CRC) 
     AMA of subjects with and without incident CRC is shown in  FIG.  10   . The AMA in patients developing CRC over time (n=93) are significantly lower compared to the non-CRC group (p=0.0008; Kruskal-Wallis). In contrast, the MR-proADM concentrations in patients developing CRC over time are higher compared to the non-CRC group (p=0.023) as shown in  FIG.  11   . 
     Results for the single markers and marker combinations are shown in Table 4. Reduced serum AMA (age-adjusted) strongly predicts development of CRC with a Hazard Ratio (HR) of 0.68 (p&lt;0.0001).  FIG.  12    shows a Kaplan-Meier Plot for the prediction of CRC with AMA (prevalent cases were excluded from the analysis). The lowest tertile is associated with the highest risk of CRC development (p&lt;0.005). 
     Increased MR-proADM concentrations predict development of CRC with a HR of 1.36 p&lt;0.05). The highest quartile is associated with the highest risk of CRC development (p=0.051). 
     While bio-ADM concentrations were not predictive for development of CRC, a combination of bio-ADM and AMA showed an improved CRC prediction (see table 4). In addition, a combination of AMA and MR-proADM further improved the prediction of CRC development. 
     In summary, reduced AMA values predict development of CRC. Increased MR-proADM concentrations also predict development of CRC. A combination of AMA with bio-ADM or MR-proADM enhances the predictive value for CRC.

     6.5. Prediction of Cardiovascular Disorders 
     Cardiovascular disorder analyses were performed in 4942 samples with information about death- and cardiovascular events from the MPP cohort. Information about cardiovascular events and diagnoses was requested from the Swedish National Patient Register (SNPR). The diagnoses in the register were collected according to different revisions of the International Classification of Diseases (ICD) codes. 
     Since 1987, SNPR includes all in-patient care in Sweden and, in addition, contains data on outpatient visits including day surgery and psychiatric care from both private and public caregivers recorded after 2000. The PAM activity (AMA) was determined as described in example 3. Within of the total set of 4942 serum samples from the MPP study cohort 278 subjects developed heart failure (incident heart failure) and 633 subjects developed atrial fibrillation (incident atrial fibrillation) during follow-up period of 12.8 years. 
     Elevated serum AMA strongly predicts incident heart failure (83 prevalent HF cases were excluded from the analyses) with a Hazard Ratio (HR) of 1.537 (CI 1.169-2.021; p&lt;0.0007) (Table 5).  FIG.  13    shows a Kaplan-Meier Plot for the prediction of heart failure using AMA. High AMA is associated with increased risk of getting heart failure. 
     Elevated serum AMA strongly predicts incident atrial fibrillation (267 prevalent AF cases were excluded from the analyses) with a Hazard Ratio (HR) of 1.459 (CI 1.214-1.752; p&lt;0.0001) (Table 5).  FIG.  14    shows a Kaplan-Meier Plot for the prediction of atrial fibrillation using AMA. High AMA is associated with increased risk of getting atrial fibrillation.

     Example 7—Diagnosis of Diseases 
     7.1. Diagnosis of Alzheimer&#39;s Disease 
     Serum samples from 27 individuals with diagnosed Alzheimer&#39;s disease were obtained from InVent Diagnostica GmbH. The AD diagnosis is based on cognitive tests (CERAD, DemTec, MMST and Clock-Drawing test) as well as on MRI (Magnetic resonance imaging) and CT-scans. As controls, 67 serum samples from self-reported healthy volunteers were used. AMA was detected as described in example 3. 
     As shown in  FIG.  15    patients from the AD-cohort showed significantly lower serum AMA when compared to the control-cohort (n=67; p&lt;0.0001). 
     7.2. Diagnosis of Cardiovascular and Metabolic Disorders 
     In the total set of 4942 serum samples from the MPP study cohort, 267 cases of prevalent atrial fibrillation, 83 cases of prevalent chronic heart failure and 533 cases of prevalent diabetes were present. Significant elevation of serum AMA (p&lt;0.0001) was observed in prevalent atrial fibrillation (mean AMA: 13.92 AMA-Units, n=267) when compared to individuals free of prevalent atrial fibrillation (mean AMA: 12.8 AMA-Units, n=4675). Significant elevation of serum AMA (p=0.0019) was observed in prevalent chronic heart failure (mean AMA: 14.31 AMA-Units, n=83) when compared to individuals free of prevalent heart failure (mean AMA: 12.84 AMA-Units, n=4859). Significant reduction of serum AMA (p=0.0035) was observed in prevalent diabetes (mean AMA: 12.69 AMA-Units, n=533) when compared to individuals free of prevalent diabetes (mean AMA: 12.89 AMA-Units, n=4409).

     Human Li-Heparin plasma (pool of 3 specimen with low ADM-Gly (&lt;50 pg/mL)) was used as source of human native PAM. The amidation reaction was performed in a total volume of 120 μl at 37° C. 96 μl of plasma were spiked with ADM-Gly (5 ng/mL final concentration). As control, equal volumes of 100 mM Tris-HCl, pH 7.5 were added to untreated plasma. The prepared samples were allowed to chill for 15 minutes at room temperature. The amidation reaction was started by addition of 24 μl of PAM-reaction buffer resulting in final concentrations of 2 mM L-ascorbate and 5 μM CuSO4, respectively, with a final concentration for ADM-Gly 4 ng/mL. After 0 min, 30 min, 60 min and 90 min of incubation at 37° C., the reaction was stopped by addition of Na-EDTA (20 mM final concentration). The concentration of bio-ADM in the reaction sample was quantified using the Sphingotest® bio-ADM immunoassay as described recently (Weber et al. 2017 . JALM  2(2): 222-233). No change in bio-ADM concentration was detected in low ADM-Gly samples without addition of exogenous ADM-Gly. When ADM-Gly was added to the sample, a linear formation of bio-ADM was detected within 90 minutes ( FIG.  16   ). 
     b) Conversion of ADM-Gly to Bio-ADM by Exogenous (Recombinant) PAM 
     In a further experiment we investigated the formation of bio-ADM from endogenous ADM-Gly by native human plasma PAM and the effect of addition of exogenous recombinant human PAM. Human Li-Heparin plasma (pool of 5 specimen with high ADM-Gly (&gt;400 pg/mL)) was used as source of human native PAM and human native ADM-Gly. The amidation reaction was performed in a total volume of 315 μl at 37° C. 250 μl of plasma were spiked with 65 μl reaction buffer with or without recombinant PAM (see Example 1) to initiate the amidation reaction. Final concentrations in the reaction samples were: 2 mM L-ascorbate, 5 μM CuSO4, 50 μM Amastatin, 200 μM Leupeptin and 100 μg/mL Catalase. The concentration of exogenous recombinant PAM was 500 ng/ml. After 0 min, 30 min, 55 min and 80 min of incubation at 37° C., the reaction was stopped by addition of Na-EDTA (20 mM final concentration). The concentration of bio-ADM in the reaction sample was quantified using the Sphingotest® bio-ADM immunoassay as described recently (Weber et al. 2017 . JALM  2(2): 222-233). The concentrations of ADM-Gly were determined as described in example 5. 
     As shown in  FIG.  17   , endogenous human PAM enzyme is capable of the conversion of endogenous human ADM-Gly to bioADM in a time-dependent manner. Moreover, ADM-Gly/bio-ADM ratio is shifted towards bio-ADM in a time dependent manner ( FIG.  18   ). These data clearly indicate that the PAM exerts its function of c-terminal amidation of peptide-hormones not only in the lumen of secretory vesicles but also in the circulation. An approximate doubling of the PAM concentration in the reaction sample by addition of exogenous recombinant human PAM leads to an increase of the bio-ADM synthesis rate from endogenous human ADM-Gly ( FIG.  17   ) by an averaged factor of 1.8 at each time-point. Furthermore, the ADM-Gly consumption is increased with a faster shift of the ADM-Gly/bio-ADM ratio towards bio-ADM ( FIG.  18   ). These in vitro findings show an unexpectedly high potential of recombinant human PAM in shifting potentially unfavourable circulating ADM-Gly/bio-ADM ratios towards bio-ADM. 
     Example 9—Application of Recombinant PAM (In Vivo Half-Life of PAM in Rats) 
     Two animals (Wistar-rat, male, 2-3 month of age) received 17 μg of recombinant human PAM (see example 1) as a single dose in a total volume of 500 μl (in phosphate-buffered saline). One control-animal received 500 μl of PBS. Blood sampling (Li-Heparin Plasma) was carried out 30 min prior to application and 30 min, 2 h, 4 h, 8 h, 24 h and 48 h, respectively, after application. 
     AMA in plasma samples was determined as described in example 3. AMA prior to application was defined as 100% and AMA after application was normalized to AMA prior to application. AMA (%) from the three animals is shown in  FIG.  19   . Half-Life of the PAM enzyme was determined from the averaged activities of the Enzyme group animals ( FIG.  20   ) using a one phase decay fit (Graph Pad Prism). The half-life of the PAM Enzyme was 47 min. 
     In a second experiment three animals (Wistar-rat, male, 2-3 month of age) received 25 μg of recombinant human PAM (see example 3) as a single dose in a total volume of 500 μl. One control-animal received 500 μl of PBS. Blood sampling (Li-Heparin Plasma) was carried out 15 minutes prior to application and 15, 30, 45, 60, 90 min as well as 2 h, 3 h, 4 h, and 8 h, respectively, after application. Half-life of the PAM enzyme was determined as described above and was with 60 min comparable to the determination described above. 
     These data clearly demonstrate the capability of intravenously administered recombinant human PAM to convert circulating ADM-Gly into bio-ADM in vivo. The administration of recombinant human PAM led to a bio-ADM increase with a maximum after 4 h with a half-life of the PAM enzyme of approximately 53.5 min. 
     Example 10—Injection of Recombinant PAM in Combination with Ascorbate in Rats 
     Endotoxin-free, recombinant PAM (SinoBiological) was buffer exchanged into sterile phosphate buffer saline (PBS, Dulbecco) and adjusted to 50 μg/mL. Sterile ascorbate solution for injection (200 mg/mL, vitamin C 1000, WÖRWAG Pharma) was purchased in a local pharmacy and adjusted under sterile conditions with PBS to 40 mg/mL. For combined injections of PAM and ascorbate, the compounds were prepared separately in equal volumes (100 μg/mL or 80 mg/mL for PAM and ascorbate, respectively). Both compounds were combined directly prior to injection to result in concentrations of 50 μg/mL for PAM and 40 mg/mL for ascorbate. Sterile PBS was used as placebo. All samples were stored at −80° C. until use. Animals, male Wistar rats, 2-3 month of age, were assigned into 4 groups (placebo, ascorbate, PAM, PAM+ascorbate) with 3 animals per group. Each animal in the individual group received 500 μl of the respective compound intravenously as a single dose injection. Blood sampling was performed as Li-Heparin 30 min prior to and 15, 30, 45, 60, 120, 180, 240 and 300 min post injection. PAM activities were determined as described in example 3. 
     Injection of Ascorbate in rats resulted in non-significant elevation of endogenous PAM activity, when measured without exogenous Ascorbate addition in assay ( FIG.  21 A , open triangles). PAM Activity remained elevated for 60 minutes after injection with its maximal elevation after 15 min past injection. After 120 min past injection measured activity was comparable to PAM activity in the placebo group. Injection of recombinant human PAM in rats resulted in highly significant elevation of circulating PAM activity, when measured without exogenous Ascorbate addition ( FIG.  21 A , filled squares). Maximal elevation of PAM activity by the factor of 6 when compared to placebo group was reached 15 minutes past injection. Circulating PAM activity remained significantly elevated for 60 minutes after injection (30 min, 45 min and 60 min) with a decreasing tendency in this time period. After 120 min past injection measured PAM activity was not significantly different to PAM activity in the placebo group. Injection of a combination of recombinant human PAM and Ascorbate in rats resulted in highly significant elevation of circulating PAM activity, when measured without exogenous Ascorbate addition ( FIG.  21 A , open squares). Maximal elevation of PAM activity by the factor of 24 when compared to placebo group was reached 15 minutes past injection. Circulating PAM activity remained significantly elevated for 60 minutes after injection (30 min, 45 min, 60 min) with a decreasing tendency in this time period. After 120 min past injection measured activity remained significantly elevated when compared to PAM activity in the placebo group. Application of enzyme- and ascorbate-free placebo did not increase the circulating PAM Activity ( FIG.  21 A , open circles). 
     The Determination of Bio-ADM in Circulation of all Treatment-Groups Surprisingly Revealed Elevation of Circulating Bio-ADM Concentration in a Time-Dependent Manner: 
     After application of Ascorbate, bio-ADM concentration was elevated (non-significant) by the factor of 1.4 after 15 min and after 30 min, by the factor of 1.2 after 45 min and returned to baseline levels after 60 minutes ( FIG.  21 B , filled circles). After application of recombinant human PAM ( FIG.  21 B , open squares), bio-ADM concentration was highly significantly elevated by the factor of 1.8 after 15 min and by the factor of 2.4 after 30 min. After 45 min bio-ADM concentrations decreased but remained significantly elevated by the factor of 2. After 60 min bio-ADM concentrations were not significantly different when compared to the placebo group. Highest elevation of circulating bio-ADM was observed in the PAM+Ascorbate combination group ( FIG.  21 B , filled squares): After application of recombinant human PAM and Ascorbate, bio-ADM concentration was highly significantly elevated by the factor of 2.3 after 15 min and by the factor of 3.2 after 30 min. After 45 min bio-ADM concentrations decreased but remained significantly elevated by the factor of 2.8. After 60 min bio-ADM concentrations remained elevated by the factor of 1.6, but the difference was not significant when compared the placebo group. In all 3 groups (Ascorbate, PAM and PAM+Ascorbate) bio-ADM concentrations were not significantly different to the Placebo group after 120 minutes. Application of enzyme- and Ascorbate-free placebo did not increase the bio-ADM concentration in plasma ( FIG.  21 B , open circles). Bio-ADM concentrations of the placebo group were set as 100% for each timepoint and bio-ADM concentrations in the treatment groups were normalized to the placebo group. 
     These data clearly demonstrate the capability of intravenously administered recombinant human PAM and a combination of recombinant human PAM with Ascorbate to convert circulating ADM-Gly into bio-ADM in vivo. The administration of recombinant human PAM led to a bio-ADM increase with a maximum after 30 minutes. 
     As shown in  FIG.  22   , the half-life of recombinant human PAM in rats is 52.7 minutes. The determined half-life is comparable to the half-life determined in example 9 ( FIG.  20   ), while the precision of the half-life determination was increased by generation of additional datapoints between 0 and 60 minutes after injection 
     Example 11—Effect of Ascorbate on Circulating Human PAM Activity 
     Healthy volunteers (n=4) received 2000 mg of vitamin C (Dr. Scheffler, Additiva® Vitamin C) as an oral single dose. Blood sampling was performed prior to- and 1, 2 and 3 hours post administration. Basal amidating activity was determined from Li-heparin plasma and serum as described in example 3 in absence of exogenous ascorbate addition and is shown in  FIG.  23   . 
     Surprisingly, PAM activity determined without exogenous ascorbate addition was significantly elevated 1 h after oral Ascorbate uptake by the factor of 1.7 when compared to PAM activity prior to ascorbate uptake ( FIG.  23   ). Further, after 2 h and 3 h post oral ascorbate uptake, PAM activity remained elevated by the factor of ˜2. These data clearly demonstrate that oral Ascorbate uptake is suitable for modulation of circulating PAM activity in humans.
