MICRORNA SIGNATURES INDICATIVE OF IMMUNOMODULATING THERAPY FOR MULTIPLE SCLEROSIS
The present invention provides methods, systems, and kits for evaluating multiple sclerosis (MS) in a patient. Particularly, the invention provides convenient miRNA-based tests for evaluating a patient for MS, including for diagnosing MS, for excluding MS as a diagnosis, and for monitoring the course of disease or efficacy of treatment, including evaluation of immunomodulating therapy.
1 - 71 . (canceled)
72 . A method for evaluating a patient's response to treatment with an immunomodulatory agent used to manage a demyelinating disease, comprising:
preparing a miRNA profile from a biofluid sample collected from the patient, and determining the presence or absence of a miRNA signature indicative of a patient's response to treatment with the immunomodulating agent, the miRNA profile comprising the measured level of at least 4 miRNAs of Table 1, Table 2, and/or Table 3.
73 . The method of claim 72 , wherein the patient has MS, and is being treated with beta-interferon.
74 . The method of claim 72 , wherein the miRNA profile is determined prior to treatment, and after treatment.
75 . The method of claim 72 , wherein the miRNA profile is determined in a serum or plasma sample.
76 . The method of claim 75 , wherein the sample is a serum sample collected with a serum separator tube.
77 . The method of claim 72 , wherein the miRNA profile comprises the level of at least 5 miRNAs of Table 1, Table 2, and/or Table 3.
78 . The method of claim 77 , wherein the miRNA profile comprises the level of at least 10 miRNAs of Table 1, Table 2, and/or Table 3.
79 . The method of claim 77 , wherein the miRNA profile comprises the level of at least 20 miRNAs of Table 1, Table 2, and/or Table 3.
80 . The method of claim 77 , wherein the miRNA profile comprises the level of at least 50 miRNAs of Table 1, Table 2, and/or Table 3.
81 . The method of claim 72 , wherein the miRNA profile comprises the level for 150 miRNAs or less.
82 . The method of claim 72 , wherein the miRNA profile comprises the level for 100 miRNAs or less.
83 . The method of claim 72 , wherein the miRNA profile comprises the level for 75 miRNAs or less.
84 . The method of claim 72 , further comprising, determining the level of one or more normalization controls in the sample.
85 . The method of claim 84 , wherein the sample is spiked with the normalization control(s).
86 . The method of claim 85 , wherein the normalization control is a non-endogenous RNA or miRNA, or a miRNA not detectable in the sample.
87 . The method of claim 72 , wherein miRNA levels are normalized to the Mean or Median detection levels for all miRNAs in the profile.
88 . The method of claim 72 , wherein miRNA profile is determined by amplification and/or hybridization-based assay.
89 . A method for preparing a miRNA profile indicative of a patient's response to immunomodulating therapy for a demyelinating disease, comprising:
preparing a miRNA profile from a biofluid sample collected from a patient suspected of having MS, the miRNA profile comprising the measured level of 150 miRNAs or less including at least 4 miRNAs of Table 1, Table 2, and/or Table 3.
90 . The method of claim 89 , wherein the patient has MS and is being treated with beta-interferon.
91 . The method of claim 90 , wherein the miRNA profile is determined prior to treatment, and after treatment.
92 . A kit for preparing a miRNA profile indicative of a responsive to immunomodulating therapy for a demyelinating disease, comprising: a miRNA-specific primer for reverse transcribing or amplifying each of 150 miRNAs or less, including at least 4 miRNAs of Table 1, Table 2, and/or Table 3.
