Definitions

  • the invention relates to the prevention and treatment of cytokine release syndrome (CRS) and neurotoxicity associated with immunotherapy.
  • CRS cytokine release syndrome
  • Immunotherapies such as chimeric antigen receptor T-cell therapies (CAR-T) and antibody-based therapies, are increasingly being used to treat a wide range of diseases, including cancers, infections, auto-immune disorders and genetic diseases.
  • immunotherapies can be associated with life-threatening side effects.
  • Cytokine release syndrome (CRS) and neurotoxicity are potentially life-threatening toxicities that can be caused by immunotherapies.
  • CRS Cytokine release syndrome
  • CRS is seen in 70-94% of patients treated with CAR-T therapy and is the most common side effect of CAR-T therapy.
  • immunotherapies such as CAR-T therapy cause aberrant activation of large numbers of white blood cells, such as B cells,
  • T cells T cells, natural killer (NK) cells, macrophages and dendritic, which release pro-inflammatory cytokines. Release of pro -inflammatory cytokines in turn leads to activation of the vascular endothelial system and loss of vascular integrity.
  • Neurotoxicity is a second side effect of immunotherapies. Neurotoxicity is almost always preceded by CRS and is also associated with markers of endothelial activation. There are currently very few treatments available for CRS and neurotoxicity, and what treatments exist are largely palliative. There thus exists a need in the art for additional methods to treat and prevent CRS and neurotoxicity. The disclosure provides compositions and methods for the treatment and prevention of CRS and neurotoxicity.

  • CAR Chimeric antigen receptor
  • CAR-T Chimeric antigen receptor T cell therapy
  • T cells from either a donor or the recipient are genetically engineered to express a specific chimeric antigen receptor designed to recognize a specific tumor associated antigen, with the expectation that the T cells will actively target and selectively kill cells expressing a specific cancer antigen.
  • CRS cytokine release syndrome
  • Immunotherapy toxicities for example CAR T-cell associated toxicities, primarily involve an exaggerated response from T-cell activation, which involves release of a broad range of cytokines led in part by IL-Ib and TNFa.
  • the specific pathophysiological mechanism is not known although the 2nd wave of cytokines, in particular IL-6 activated by IL-Ib, appears to result in aberrant activation of the vascular endothelial system (Hay 2017, Santomasso 2018,
  • CAR T-cells do not directly produce IL-6, and monocyte-derived IL-Ib is strongly implicated in driving IL-6 and the overall CRS and neurotoxicity due to CAR T-cells (Norelli 2018; Giavridis 2018).
  • IL-6 levels nor CRS are required for an effective antitumor response (Titov 2018) to CAR-T therapy. Therefore, treatments that reduce IL-Ib and/or IL-6 driven inflammation, will not reduce the effectiveness of CAR-T therapy while at the same time reducing the harmful effects of CRS and/or neurotoxicity.
  • tocilizumab The IL-6 receptor antagonist, tocilizumab, is the only currently approved agent for the treatment of CRS. Evidence to date suggests that treatment of CRS with tocilizumab does not affect CAR T-cell efficacy (Singh 2017). However, tocilizumab, an injectable antibody, is in and of itself associated with a number of adverse effects.
  • Neurotoxicity is a second complication that presents as an encephalopathy and may or may not include aphasia and is somewhat distinct from CRS (Guitierrez 2018; Santomasso 2018; Gust 2017; Titov 2018).
  • CRS Cerebral Reactive protein
  • Autopsies from patients who died from neurotoxicity showed disrupted endothelium with reactive microglia in a perivascular distribution (Gust 2017; Echeverry 2019).
  • CAR T-cells infiltrate the brain, but the presence of CAR T-cells in the brain has not correlated with severity of neurotoxicity (Gust 2017; Echeverry 2019).
  • the IL-6 inhibitor tocilizumab has been used to ameliorate neurotoxicity but has been less effective at reversing symptoms of neurotoxicity than symptoms of CRS (Neelapu 2017; Santomasso 2018). Tocilizumab does not readily penetrate the central nervous system and has been reported to increase serum IL-6 concentration by interfering with IL-6 clearance through uptake in peripheral tissues (Neelapu 2017; Echeverry 2019). [0024] Therefore, there is a need for additional therapies for CRS and/or neurotoxicity, and to more precisely target therapies for CRS and/or neurotoxicity to those subjects who will derive a therapeutic benefit, which are provided by the instant disclosure.
  • the present invention is based upon the discovery that inflammation, such as that caused by an overproduction of IL-1, is associated with an increased risk of developing CRS and neurotoxicity in response to immunotherapy, and that specific IL-1 genotype patterns stratify subjects into groups relating to their member’s likelihood of over-producing IL-1. It is thus possible to specifically target subjects who have high levels of inflammation and who are at risk of developing, or who have developed CRS or neurotoxicity for treatment with IL-1 inhibitors, IL-6 inhibitors, and other therapies.
  • Subjects can be stratified into one of two IL-1 genotype patterns, i.e., positive or negative, based upon their complex IL-1 genotype for three or five single nucleotide polymorphisms (SNPs) in the IL-1 locus.
  • SNPs single nucleotide polymorphisms
  • a subject having an uncommon complex IL-1 genotype not exemplified in Tables 1-3 is considered herein as having an IL-1 genotype pattern of “Negative”.

  • LD linkage disequilibrium
  • a subject of certain racial/ethnic groups may be stratified into an IL-1 genotype pattern based upon five SNP loci listed in Table 1.
  • Other racial/ethnic groups may require three SNP loci (as in Table 2 or Table 3) to be stratified into an IL-1 genotype pattern. Differences in the frequencies or even the absence of a specific SNP in certain racial/ethnic groups may require the inclusion of additional informative SNPs.

  • the inventors have identified 3 haplotype pairs that are predictably high producers of IL-Ib and 3 pairs that are predictably lower producers of IL-Ib and 4 pairs that are somewhere in the middle.
  • the high IL-1 producing haplotype pairs chronically produce approximately 30% higher tissue levels than the 3 lower producers.
  • haplotype context is required for the different functional SNPs working together to regulate transcription of the IL1B gene in response to complex activation of transcription.
  • the haplotypes of the instant disclosure are unambiguously determined from the composite genotype of the subject.
  • Routine mathematical projections used in genotyping are based upon certain assumptions about the general population that may be influenced in the individual due to ancestry of the population from which they come. That means that for almost any place in North America, South America, and Europe, the admixture must be considered and therefore modifies the accuracy of the projection.
  • the ability to unambiguously define the two haplotypes carried by a specific subject provides greater precision in identifying which two haplotypes are carried by that subject. That capability exists because out of 8 possible haplotypes from 3 functional SNPs assayed, only 4 of the 8 are actually observed in nature across all major racial populations.

  • both the reporter and the quencher may be attached to internal nucleotides at a distance from each other such that fluorescence of the reporter is reduced.
  • DNA polymerase cleaves the probe, thereby separating the reporter dye and the quencher dye and resulting in increased fluorescence of the reporter. Accumulation of PCR product is detected directly by monitoring the increase in fluorescence of the reporter dye.
  • the DNA polymerase cleaves the probe between the reporter dye and the quencher dye only if the probe hybridizes to the target SNP-containing template which is amplified during PCR, and the probe is designed to hybridize to the target SNP site only if a particular SNP allele is present.
  • Preferred TaqMan® primer and probe sequences can readily be determined using the SNP and associated nucleic acid sequence information provided herein.
  • a number of computer programs such as Primer Express (Applied Biosystems, Foster City, Calif.), can be used to rapidly obtain optimal primer/probe sets. These probes and primers can be readily incorporated into a kit format.
  • the disclosed subject matter also includes modifications of the TaqMan® assay well known in the art such as the use of Molecular Beacon probes (U.S. Pat. Nos. 5,118,801 and 5,312,728) and other variant formats (U.S. Pat. Nos. 5,866,336 and 6,117,635).
  • Another method for genotyping the SNPs can be the use of two oligonucleotide probes in an OLA (see, e.g., U.S. Pat. No. 4,988,617).
  • one probe hybridizes to a segment of a target nucleic acid with its 3' most end aligned with the SNP site.
  • a second probe hybridizes to an adjacent segment of the target nucleic acid molecule directly 3' to the first probe.
  • the two juxtaposed probes hybridize to the target nucleic acid molecule and are ligated in the presence of a linking agent such as a ligase if there is perfect complementarity between the 3 ' most nucleotide of the first probe with the SNP site. If there is a mismatch, ligation would not occur.
  • the ligated probes are separated from the target nucleic acid molecule and detected as indicators of the presence of a SNP.
  • OLA OLA
  • LDR LDR
  • PCR nucleic acid amplification
  • Mass spectrometry takes advantage of the unique mass of each of the four nucleotides of DNA. SNPs can be unambiguously genotyped by mass spectrometry by measuring the differences in the mass of nucleic acids having alternative SNP alleles.
  • MALDI-TOF Microx Assisted Laser Desorption Ionization-Time of Flight mass spectrometry technology is preferred for extremely precise determinations of molecular mass, such as SNPs.
  • Numerous approaches to SNP analysis have been developed based on mass spectrometry.
  • Preferred mass spectrometry-based methods of SNP genotyping include primer extension assays, which can also be utilized in combination with other approaches, such as traditional gel -based formats and microarrays.
  • a mass spectrometry with primer extension assay involves designing and annealing a primer to a template PCR amplicon upstream (5') from a target SNP position.
  • a mix of dideoxynucleotide triphosphates (ddNTPs) and/or deoxynucleotide triphosphates (dNTPs) are added to a reaction mixture containing template (e.g., a SNP-containing nucleic acid molecule which has typically been amplified, such as by PCR), primer, and DNA polymerase.
  • template e.g., a SNP-containing nucleic acid molecule which has typically been amplified, such as by PCR
  • primer e.g., a SNP-containing nucleic acid molecule which has typically been amplified, such as by PCR
  • DNA polymerase e.g., a SNP-containing nucleic acid molecule which has typically been amplified, such as by PCR
  • the primer can be either immediately adjacent (i.e., the nucleotide at the 3' end of the primer hybridizes to the nucleotide next to the target SNP site) or two or more nucleotides removed from the SNP position. If the primer is several nucleotides removed from the target SNP position, the only limitation is that the template sequence between the 3' end of the primer and the SNP position cannot contain a nucleotide of the same type as the one to be detected, or this will cause premature termination of the extension primer.
  • primers are designed to bind one nucleotide upstream from the SNP position (i.e., the nucleotide at the 3' end of the primer hybridizes to the nucleotide that is immediately adjacent to the target SNP site on the 5' side of the target SNP site). Extension by only one nucleotide is preferable, as it minimizes the overall mass of the extended primer, thereby increasing the resolution of mass differences between alternative SNP nucleotides.
  • mass-tagged ddNTPs can be employed in the primer extension reactions in place of unmodified ddNTPs. This increases the mass difference between primers extended with these ddNTPs, thereby providing increased sensitivity and accuracy, and is particularly useful for typing heterozygous base positions.
  • Primer extension assays may be used in conjunction with MALDI-TOF mass spectrometry for SNP genotyping, see, e.g., Wise el al., “A standard protocol for single nucleotide primer extension in the human genome using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry,” Rapid Comm. Mass Spect. 17 (11): 1195-202 (2003).
  • SNPs can also be scored by direct DNA sequencing.
  • a variety of automated sequencing procedures can be utilized (e.g., Biotechniques 19:448 (1995)), including sequencing by mass spectrometry. See, e.g., PCT International Publication No. WO 94/16101; Cohen et al., Adv Chromatogr 36:127-162 (1996); and Griffin et al, Appl Biochem Biotechnol 38:147-159 (1993).
  • the nucleic acid sequences of the disclosed subject matter enable one of ordinary skill in the art to readily design sequencing primers for such automated sequencing procedures.
  • Commercial instrumentation such as the Applied Biosystems 377, 3100, 3700, 3730, and 3730x1 DNA Analyzers (Foster City, Calif.), is commonly used in the art for automated sequencing.
  • SSCP single-strand conformational polymorphism
  • DGGE denaturing gradient gel electrophoresis
  • the different electrophoretic mobilities of single- stranded amplification products are related to base-sequence differences at SNP positions.
  • DGGE differentiates SNP alleles based on the different sequence- dependent stabilities and melting properties inherent in polymorphic DNA and the corresponding differences in electrophoretic migration patterns in a denaturing gradient gel.
  • Sequence-specific ribozymes can also be used to score SNPs based on the development or loss of a ribozyme cleavage site. Perfectly matched sequences can be distinguished from mismatched sequences by nuclease cleavage digestion assays or by differences in melting temperature. If the SNP affects a restriction enzyme cleavage site, the SNP can be identified by alterations in restriction enzyme digestion patterns, and the corresponding changes in nucleic acid fragment lengths determined by gel electrophoresis.
