SEQUENCE LISTING

The instant application contains a Sequence Listing which has been submitted electronically in ASCII format and is hereby incorporated by reference in its entirety. Said ASCII copy, created on Jul. 16, 2021, is named 104545-0061-101-SL.txt and is 149,920 bytes in size.


BACKGROUND OF THE DISCLOSURE

The novel coronavirus is referred to as SARS-CoV-2 or 2019-nCoV and is related to Severe Acute Respiratory Syndrome coronavirus (SARS-CoV), although with only approximately 80% similarity at the nucleotide level. Ralph et al. J Infect Dev Ctries. 2020 Jan. 31; 14(1):3-17. The infectious disease caused by SARS-CoV-2 has been named COVID-19 and its symptoms, depending on the infective strain, include fever, cough, fatigue, shortness of breath, and loss of smell and taste.


Coronaviruses are enveloped single stranded RNA viruses with positive-sense RNA genomes ranging from 25.5 to ˜32 kb in length. The spherical virus particles range from 70-120 nm in diameter and contain four structural proteins: the E and M proteins, which form the viral envelope; the N protein, which binds to the virus's RNA genome; and the S protein, which binds to human receptors. The genome of SARS-CoV-2 also comprises a number of open reading frames that code for a total of nine accessory proteins, which are not essential for virus replication.


Despite the fact that much effort is currently being invested into methods of detecting SARS-CoV-2, there is still a need to provide additional and improved approaches to detect SARS-CoV-2 and developed immunity, particularly cell-mediated immunity, to SARS-CoV-2. At present, the available methods to assess cell-mediated immune responses require highly specialized laboratories and in vitro techniques to detect cytokine synthesis or production following antigenic challenge in culture. Because these methods rely on surrogate markers, they may not reflect functional in vivo immunity. In addition, they are subject to inter-lab variability, expensive, time consuming and challenging to scale up. Thus, there is a need for improved methods for assessing cell-mediated immune responses to SARS-CoV-2 infection and/or vaccination.


SUMMARY OF THE DISCLOSURE

In some aspects, the present disclosure provides methods and kits for detecting cell-mediated SARS-CoV-2 immunity in a subject, methods and kits for detecting a cell-mediated immune response to SARS-CoV-2 in a subject, methods and kits for detecting a SARS-CoV-2 infection in a subject and methods and kits for determining if a potential or approved vaccine against SARS-CoV-2 elicits a cell-mediated immune response in a subject.


The skin detection methods and kits of the disclosure are based on one or more peptides derived from one of the SARS-CoV-2 proteins and administering them to the skin of a subject. If the subject is infected with SARS-CoV-2, has had exposure to SARS-CoV-2 or has developed cell-mediated immunity to SARS-CoV-2 (e.g., by vaccination), these peptides elicit a cellular immunity response or cell-mediated immune response (i.e., CD4+ and/or CD8+ T cell responses) that can be detected by inspection of the area of the skin where the peptide(s) has been administered. One of the benefits of using the peptides disclosed herein, rather than larger proteins, is that smaller peptides are less likely to trigger IgE immune reactions in sensitized hosts. Another advantage of using the peptides disclosed herein is that the peptides are less likely to elicit a humoral response and the individual, therefore, does not produce antibodies against the peptides, as might be the case using the whole protein or a protein derivative. A further benefit of the methods of the disclosure is that they can detect SARS-CoV-2 immunity in a subject, even if the subject is seronegative and as well as in subjects with a history of asymptomatic or mild COVID-19. Additional benefits include ease of administration and timely read out, scalability and cost.

Peptide synthesis reactions and purification techniques are performed according to manufacturer's specifications, as commonly accomplished in the art or as described herein. The nomenclatures used in connection with, and the laboratory procedures and techniques of, analytical chemistry, biochemistry, immunology, molecular biology, synthetic organic chemistry, and medicinal and pharmaceutical chemistry described herein are those well-known and commonly used in the art.


Throughout this specification and embodiments, the word “comprise,” or variations such as “comprises” or “comprising,” will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers. “Comprising” may be synonymous with “including” or “containing.”


It is understood that wherever embodiments are described herein with the language “comprising,” otherwise analogous embodiments described in terms of “consisting of” and/or “consisting essentially of” are also provided. As used herein, “consisting of” is a closed term that includes only the specific elements recited, and “consisting essentially of” includes the specific elements recited and may include additional unrecited, nonmaterial elements.


The term “including” is used to mean “including, but not limited to.” “Including” and “including but not limited to” are used interchangeably.


Any example(s) following the term “e.g.” or “for example” is not meant to be exhaustive or limiting.


Unless otherwise required by context, singular terms shall include pluralities and plural terms shall include the singular.


The articles “a”, “an” and “the” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element. As used herein, the term “about” modifying the quantity of an ingredient, parameter, calculation, or measurement in the compositions of the disclosure or employed in the methods of the disclosure refers to variation in the numerical quantity that can occur, for example, through typical measuring and liquid handling procedures used for making isolated polypeptides or pharmaceutical compositions in the real world; through inadvertent error in these procedures; through differences in the manufacture, source, or purity of the ingredients employed to make the compositions or carry out the methods; and the like without having a substantial effect on the chemical or physical attributes of the compositions or methods of the disclosure. Such variation can be within an order of magnitude, typically within 10%, more typically still within 5%, of a given value or range. The term “about” also encompasses amounts that differ due to different equilibrium conditions for a composition resulting from a particular initial mixture. Whether or not modified by the term “about”, the paragraphs include equivalents to the quantities. Reference to “about” a value or parameter herein includes (and describes) embodiments that are directed to that value or parameter per se. For example, description referring to “about X” includes description of “X.” Numeric ranges are inclusive of the numbers defining the range.


Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Moreover, all ranges disclosed herein are to be understood to encompass any and all subranges subsumed therein. For example, a stated range of “1 to 10” should be considered to include any and all subranges between (and inclusive of) the minimum value of 1 and the maximum value of 10; that is, all subranges beginning with a minimum value of 1 or more, e.g., 1 to 6.1, and ending with a maximum value of 10 or less, e.g., 5.5 to 10.


Definitions

The following terms, unless otherwise indicated, shall be understood to have the following meanings:


As used herein, the terms “immune reaction” and “immune response” are used interchangeably herein and refer to the reaction of a subject's immune system to the presence of a substance which is not recognized as a constituent of the subject itself. An immune response may be a humoral immune response, a cell-mediated immune response, or a mixed humoral and cell-mediated immune response. A humoral response may be an antibody-mediated response. A cell-mediated response may be one or more of a cytotoxic T-cell mediated immune response, a macrophage mediated response, a natural killer (NK) cell mediated immune response or a cytokine mediated response. A mixed humoral and cell-mediated response may be one or more of an antibody-mediated response, a cytotoxic T-cell mediated immune response, a macrophage mediated response, a natural killer (NK) cell mediated immune response or a cytokine mediated response. The immune response can refer to an adaptive and/or an innate immune response. For the various types of immune responses, see David Chaplin (J Allergy Clin Immunol February; 125(2 Suppl 2): S3-23 (2010)). In some embodiments, the immune reaction corresponds to a delayed type hypersensitivity reaction (DTH) in the subject. See, e.g., Razzaque Ahmed et al.; Arch Dermatol. 1983; 119(11):934-945; incorporated by reference herein in its entirety.


The term “immunity”, as used herein, refers to the capability of a subject to resist invasive microorganisms or pathogens from entering its cells or replicating within the cells. Immunity involves both specific and non-specific components. The non-specific components act as barriers or eliminators of a wide range of pathogens irrespective of their antigenic make-up. Other components of the immune system adapt themselves to each new pathogen encountered and can generate pathogen-specific immunity.


The term “induration”, as used herein, refers to a localized hardening of soft tissue in the skin, caused by the swelling or inflammation of the skin.


The terms “cell-mediated immune response”, “cell-mediated immunity”, “T cell mediated immune response” and “T cell mediated immunity” are used interchangeably herein and refer to the primary response in a subject mainly against invasive microorganisms that cause intracellular infections. Naive T cells, which are immature T cells that have yet to encounter an antigen (such as the microorganism), are converted into activated effector T cells after encountering antigen-presenting cells (APCs). These APCs, such as macrophages, dendritic cells, and B cells in some circumstances, load antigenic peptides onto the MHC of the cell, in turn presenting the peptide to receptors on T cells. The cell-mediated immune response, therefore, involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes (CD8+ cells) and the release of various cytokines in response to antigen. CD4+ cells or helper T cells are also activated by APC. The cell-mediated response may be Type IV hypersensitivity or Delayed Type Hypersensitivity (DTH). The DTH response is caused when CD4+ Th1 helper T cells recognize foreign antigen in a complex with the MHC class II on the surface of antigen-presenting cells. These can be macrophages that secrete IL-12, which stimulates the proliferation of further CD4+ Th1 cells. CD4+ T cells secrete IL-2 and interferon gamma, inducing the further release of other Th1 cytokines, thus mediating the immune response. Activated CD8+ T cells destroy target cells on contact, whereas activated macrophages produce hydrolytic enzymes and, on presentation with certain intracellular pathogens, transform into multinucleated giant cells.


The term “intradermal application” or “intradermal administration”, as used herein, refers to the administration of a composition comprising the one or more peptides of the disclosure to the epidermis or dermis layer. It includes administrations where the composition is delivered directly to the dermis (e.g. by a device which passes entirely through the epidermis to the dermis) and those where the composition is first delivered into the epidermis by penetration of the epidermis, wherein the composition then moves through the epidermis to the dermis.


The terms “patient”, “subject”, or “individual” are used interchangeably herein and refer to either a human or a non-human animal. These terms include mammals, such as humans, primates, livestock animals (including bovines, porcines, camels, etc.), companion animals (e.g., canines, felines, etc.), animals present in a zoo and rodents (e.g., mice and rats).


The terms “polypeptide” and “protein” are used interchangeably and refer to chains of amino acids of greater than about 50 amino acids. The chain may be linear or branched, it may comprise modified amino acids, and/or may be interrupted by non-amino acids. The terms also encompass an amino acid chain that has been modified naturally or by intervention; for example, disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation or modification, such as conjugation with a labeling component. Also included within the definition are, for example, polypeptides containing one or more analogs of an amino acid (including, for example, unnatural amino acids, etc.), as well as other modifications known in the art. It is understood that the polypeptides can occur as single chains or associated chains.


The terms “oligopeptide” and “peptide” are used interchangeably and refer to a sequence of amino acids made up of a single chain of amino acids joined by peptide bonds. In some embodiments, peptides contain between 2-30 amino acids in length, unless otherwise defined. In some embodiments, peptides contain between 2-50 amino acids in length, unless otherwise defined. The terms also encompass an amino acid chain that has been modified naturally or by intervention; for example, disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation or modification, such as conjugation with a labeling component. Also included within the definition are, for example, peptides containing one or more analogs of an amino acid (including, for example, unnatural amino acids, etc.), as well as other modifications known in the art.


As used herein, “purify,” and grammatical variations thereof, refers to the removal, whether completely or partially, of at least one impurity from a mixture containing the polypeptide and one or more impurities, which thereby improves the level of purity of the polypeptide of the disclosure (i.e., by decreasing the amount (ppm) of impurity(ies) in the composition). A peptide can be “purified” using routine methods known to one of skill in the art including, but not limited to, chromatography.


As used herein, the term “residue” in the context of a polypeptide or peptide refers to an amino-acid unit in the linear polypeptide or peptide chain. It is what remains of each amino acid, i.e —NH—CHR—C—, after water is removed in the formation of the polypeptide from α-amino-acids, i.e. NH2-CHR—COOH.


The term “sequence identity,” in all its grammatical forms, refers to the degree of identity or correspondence between nucleic acid or amino acid sequences that may or may not share a common evolutionary origin.


As used herein, “substantially pure” refers to material which is at least 50% pure (i.e., free from contaminants), more preferably, at least 90% pure, more preferably, at least 95% pure, yet more preferably, at least 98% pure, and most preferably, at least 99% pure.


The term “vaccine” or “vaccination” to SARS-CoV-2, as used herein, refers to a composition comprising at least one immunologically active component that is potentially or is capable of inducing an immunological response in an animal to SARS-CoV-2; and possibly, but not necessarily, comprises one or more additional components that enhance the immunological activity of the active component. A vaccine may additionally comprise further components typical to pharmaceutical compositions. The immunologically active component of a vaccine to SARS-CoV-2 may comprise, for example, complete virus particles in either their original form or as attenuated particles (modified live vaccine), or particles inactivated by appropriate methods (killed or inactivated vaccine). In other embodiments, the immunologically active component of a vaccine may comprise appropriate elements of the organisms (subunit vaccines) that are capable of stimulating the immune system. The immunologically active component may be a protein of the viral envelope. The immunologically active component may comprise a protein forming part of the nucleocapsid. In some embodiments, the immunologically active component of a vaccine against SARS-CoV-2 comprises a structural protein (e.g., the Spike protein (S), the Membrane protein (M), the Nucleocapsid protein (N) and the Envelope protein (E)).


As used herein, the term “variant” refers to a polypeptide or peptide having a substantial sequence identity to a reference polypeptide or peptide. A variant can have deletions, substitutions, additions of one or more amino acids in comparison to the reference polypeptide. Similarities and/or differences in sequences between a variant and the reference polypeptide can be detected using conventional techniques known in the art, for example Western blot. Generally, a variant of a polypeptide, can have at least about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99% or more sequence identity to the reference polypeptide as determined by sequence alignment programs known by skilled artisans.


As used herein, the term “superantigen region”, also referred to as “superantigen domain,” refers to a sequence (e.g., peptide sequence) that potentially engages a T cell receptor and elicits a T cell response.


Each embodiment described herein may be used individually or in combination with any other embodiment described herein.

The term conservative substitution, when describing a peptide, refers to a change in the amino acid composition of the peptide that does not substantially alter the peptide's activity. For example, a conservative substitution refers to substituting an amino acid residue for a different amino acid residue that has similar chemical properties. Examples of conservative amino acid substitutions include, but are not limited to, replacement of a leucine with an isoleucine or valine, an aspartate with a glutamate, or a threonine with a serine. In some embodiments, a conservative substitution of a particular amino acid sequence refers to substitution of those amino acids that are not critical for polypeptide activity or substitution of amino acids with other amino acids having similar properties (e.g., acidic, basic, positively or negatively charged, polar or non-polar) such that the substitution of even critical amino acids does not reduce the activity of the peptide. Conservative substitution providing functionally similar amino acids are well-known in the art. For example, the following six groups each contain amino acids that are conservative substitutions for one another: (1) Alanine (A), Serine (S), Threonine (T); (2) Aspartic acid (D), Glutamic acid (E); (3) Asparagine (N), Glutamine (Q); (4) Arginine (R), Lysine (K); (5) Isoleucine (I), Leucine (L), Methionine (M), Valine (V); and (6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W). (See, also Creighton, Proteins, W. H. Freeman and Company (1984), incorporated by reference herein in its entirety). In some embodiments, for ease of synthesis, one or more cysteines in a peptide of this disclosure may be replaced with serine. In some embodiments, for ease of synthesis, one or more peptides of this disclosure may be truncated. In some embodiments, for ease of synthesis, one or more peptides of this disclosure may be synthesized and used in fragments or recombined into single peptide.


Methods to produce the peptides of the disclosure are well-known in the art. See, e.g., Lloyd-Williams P. et al. (1997) Chemical approaches to the synthesis of peptides and proteins. CRC Press. Boca Raton and N. Leo Benoiton (2006) Chemistry of Peptide Synthesis. CRC Press. Boca Raton; incorporated by reference herein in their entireties.


In some embodiments, the one or more peptides of the disclosure are manufactured through solid-phase peptide synthesis (SPPS). In some embodiments, the solid support, for example, consists of small, polymeric resin beads functionalized with reactive groups (such as amine or hydroxyl groups) that link to the nascent peptide chain. In some embodiments, the protection of the N-terminal and side chains is performed using the Boc/Bzl or Fmoc/tBu SPPS approaches.


In some embodiments, the one or more peptides of the disclosure are manufactured as Trifluoroacetate (TFA) salts. In some embodiments, the residual TFA present in the peptides is removed before using any of the peptides in the methods of the disclosure.


Methods to purify peptides are well-known in the art. See, e.g., Insuasty Cepeda D S et al. Molecules. 2019; 24(7):1215; incorporated by reference herein in its entirety. In some embodiments, the peptides of the disclosure are purified through Ultra Performance Liquid Chromatography (UPLC). A skilled in the art will know methods to identify and to determine the purity of the manufactured peptides. In some embodiments, the one or more peptides of the disclosure are substantially pure.

In some embodiments, upon the administration of the one or more peptides to the skin of the subject, an immune reaction corresponding to a cell-mediated immune response is triggered. In some embodiments, the immune reaction observed is a delayed type hypersensitivity (DTH) reaction. In some embodiments, the immune reaction is detected by inspecting the skin region in the area of the administration. In some embodiments, the inspection of the skin region is performed visually by an individual. In some embodiments, the inspection of the skin region is performed by an automatic device.


In some embodiments, upon the administration of the one or more peptides to the skin of the subject, the skin region in the area of the administration is swelled as a consequence of the immune reaction, for example, an induration (a localized hardening of soft tissue) is produced at the area of the administration. In some embodiments, the swelling at the skin region is observed within about 12 to 72 hours, within about 24 to 72 hours or within about 24 to 48 hours after the administration. In some embodiments, the peak of the swelling at the skin region is observed within about 12 to 72 hours, within about 24 to 72 hours or within about 24 to 48 hours after the administration. In some embodiments, an induration or reaction of more than about 2 mm, more than about 3 mm, more than about 5 mm, more than about 7 mm, more than about 10 mm, more than about 15 mm or more, in diameter is considered an immune reaction or a positive immune reaction in the subject. In some embodiments, the immune reaction is measured visually by an individual. In some embodiments, the immune reaction is measured by using a laser Doppler imaging (Harrison, et al., Physiol Meas. 1993 August; 14(3):241-52), using a hand-held spectrophotometer to measure the DTH reaction (Chambers, et al., Skin Res Technol. 2002 May; 8(2):89-93) or by ultrasonographic measurement (Ciftci, et al., Reading. Infect Dis Clin Pract (Baltim Md.) 2005; 13:20-23). In some embodiments, the skin test is read or inspected at about 48 hours after administration and measurements are made across two diameters in the indurated area. In some embodiments, the mean of the longest and midpoint orthogonal diameters of the indurated area is reported as the DTH reaction. For example, a reaction that is about 10 mm (longest diameter) by about 8 mm (midpoint orthogonal diameter) has a sum of about 18 mm and a mean of about 9 mm. The DTH response is therefore about 9 mm.


In some embodiments, upon the administration of the one or more peptides to the skin of the subject, the skin region in the area of the administration is swelled as a consequence of the immune reaction, for example, an induration (a localized hardening of soft tissue) is produced at the area of the administration. In some embodiments, the swelling at the skin region is observed within about 12 to 72 hours, within about 24 to 72 hours, within about 24 to 48 hours, within about 24 to 96 hours, within about 48 to 96 hours or within about 48 to 72 hours after the administration. In some embodiments, the peak of the swelling at the skin region is observed within about 12 to 72 hours, within about 24 to 72 hours, within about 24 to 48 hours, within about 24 to 96 hours, within about 48 to 96 hours or within about 48 to 72 hours after the administration. In some embodiments, the skin test is read or inspected at about 72 hours after administration and measurements are made across two diameters in the indurated area. In some embodiments, the skin test is read or inspected at about 72 hours after administration and measurements are made across two diameters in the indurated area. In some embodiments, the skin test is read or inspected at about 96 hours after administration and measurements are made across two diameters in the indurated area. In some embodiments, the skin test is read or inspected at about 96 hours after administration and measurements are made across two diameters in the indurated area.


In some embodiments, an induration or reaction of less than about 2 mm, less than about 3 mm, less than about 4 mm, or less than about 5 mm in diameter is considered a negative immune reaction or a negative immune reaction in the subject. In some embodiments, the administered negative control causes no induration or reaction to the skin of the subject. In some embodiments, the induration or reaction of the administered negative control is weaker than the administered one or more peptides to the skin of the subject.


In some embodiments, the observed immune reaction in the subject is indicative of the subject having developed cell-mediated immunity to SARS-CoV-2. In some embodiments, the observed immune reaction in the subject is indicative of the subject having developed a cell-mediated immune response to SARS-CoV-2. In some embodiments, the observed immune reaction in the subject is indicative of a potential vaccine or an approved vaccine to SARS-CoV-2 eliciting a cell-mediated immune response in the subject. In some embodiments, the observed immune reaction in the subject is indicative of the subject having an active SARS-CoV-2 infection.


In some embodiments, the one or more peptides are administered to the skin with a syringe, a microneedle patch, a lancet or the like. In some embodiments, a 26 to 30-gauge needle is used for the administration. In some embodiments, the one or more peptides are administered with a microneedle patch. See, e.g., Mandal et al., Sci. Transl. Med. 10, eaar2227 (2018) and McCormick T, Shearer W. 2006. Delayed-Type Hypersensitivity Skin Testing, p 234-240, incorporated by reference herein in their entireties.

EXAMPLES
Example 1. Generation of the Peptides of the Disclosure

The peptides of the disclosure are manufactured through solid-phase peptide synthesis (SPPS) in accordance with a general method as described in Lloyd-Williams P. et al. (1997) Chemical approaches to the synthesis of peptides and proteins. CRC Press. Boca Raton. The solid support consists of small, polymeric resin beads functionalized with reactive groups that link to the nascent peptide chain. The protection of the N-terminal and side chains is performed using the Boc/Bzl or Fmoc/tBu SPPS.


The peptides are manufactured as Trifluoroacetate (TFA) salts. The residual TFA present in the peptides is removed before using any of the peptides in the methods of the disclosure.


The peptides of the disclosure are purified through Ultra Performance Liquid Chromatography (UPLC). This step separates the peptides from impurities from the synthesis steps, such as isomers, deletion sequences, peptide products from side reactions with free coupling and protecting groups or peptides that have undergone side-chain reactions. The peptides purity is measured as a percentage of the peptide to impurities that absorb at the peptide bond absorption wavelength (210-220 nm). The peptides purity obtained is preferably higher than 85%.


Lyophilized peptides are extracted with a solution of NaCl, NaHCO3 and glycerol. Prior to the administration in the skin, the peptides are prepared in a solution comprising Polysorbate 80 and phenol in a sterile isotonic phosphate buffered saline.


Example 2. Skin Test to Detect a Cell-Mediated Immune Response Against SARS-CoV-2

The skin test preparation consists of 3 pools of peptides: (1) peptides of SEQ ID NO: 1-45; (2) peptides of SEQ ID NO: 46-167 and (3) peptides of SEQ ID NO: 168-183. The peptides are tested in a group of subjects by intradermally injecting the pools of peptides and a negative control (only solvent) in the ventral surface of the forearm, about 1 mm to about 2 mm within the dermis. 1 μg of the pools of peptides is injected intradermally in a 0.1 ml solution.


The skin reaction is monitored about 48 to 72 hours post-injection by measuring the longest and midpoint orthogonal diameters of the indurated area in millimeters. The mean of the longest and midpoint orthogonal diameters of the indurated area is reported as the DTH response. Reactions are considered positive when the induration is about >10 mm in diameter about 48 hours after injection. Reactions are also further monitored at about 72 hours to 96 hours.


A positive immune reaction in a subject is indicative of the subject having developed a cell-mediated immune response to SARS-CoV-2 and, therefore, has developed cell-mediated immunity against SARS-CoV-2 or has an active SARS-CoV-2 infection. The skin tests may be also correlated with a serological immune response and any symptoms present in the subject.


Example 3. Skin Test to Determine if a Potential or Approved Vaccine Against SARS-CoV-2 Elicits a Cell-Mediated Immune Response

Subjects are vaccinated with a candidate or approved vaccine against SARS-CoV-2. The peptides of the disclosure are further administered to those subjects to determine if the vaccine elicits a cell-mediated immune response.


The skin test preparation consists of 3 pools of peptides: (1) peptides of SEQ ID NO: 1-45; (2) peptides of SEQ ID NO: 46-167 and (3) peptides of SEQ ID NO: 168-183. The peptides are tested in a group of subjects by intradermally injecting the pools of peptides and a negative control (only solvent) in the ventral surface of the forearm, about 1 mm to about 2 mm within the dermis. 1 μg of the pools of peptides is injected intradermally in a 0.1 ml solution.


The skin reaction is monitored about 48 to 72 hours post-injection by measuring the longest and midpoint orthogonal diameters of the indurated area in millimeters. The mean of the longest and midpoint orthogonal diameters of the indurated area is reported as the DTH response. Reactions are considered positive when the induration is about >10 mm in diameter about 48 hours after injection. Reactions are also further monitored at about 72 hours to 96 hours.


A positive immune reaction in a subject is indicative of the vaccine having elicited a cell-mediated immune response in the subject. The skin tests may also be correlated with another assay that determines the clinical benefit of the vaccine, such as Enzyme-Linked Immunosorbent spot (ELISpot) assay, which is commonly used to measure antigen-specific T cells in humans.


Example 4. Skin Test Using the Methods of this Disclosure

125 subjects are separated into 5 cohorts. Cohort 1 includes 25 healthy uninfected or unexposed subjects (“naïve”). Cohort 2 includes 25 subjects with acute SARS-CoV-2 infection or symptomatic SARS-CoV-2 infection (“active infection”). Cohort 3 includes 25 subjects who test positive via, for example, real-time polymerase chain reaction for SARS CoV-2 viral RNA but are asymptomatic or with mild symptoms of SARS-CoV-2 infection (“shedders”). Cohort 4 includes 25 subjects who recovered from SARS-CoV-2 infection and are at least 2 months past recovery of SARS-CoV-2 infection (“convalescent”). Cohort 5 includes 25 subjects with SARS-CoV-2 antigen exposure, but no history of SARS-CoV-2 infection (“spike-immune”). Cohort 5 may include (but is not limited to) subjects participating in SARS-CoV-2 spike vaccine trials.


The study consists of a pre-screening check, an administration visit, a follow-up visit and an End of Study (EoS) follow-up by telephone. The duration of the study from screening to the end of the study is approximately 4 weeks. Subjects satisfying all inclusion/exclusion criteria at Visit 1 undergo a nasopharyngeal (NP) swab and blood samples are collected for peripheral blood mononuclear cell (PBMC) assays and routine clinical laboratory tests.


Each subject is intradermally injected with a 0.1 mL dose of one or more of the following:


1) Peptide Pool 1: SEQ ID NO: 1-10, 12-25, 27, 28, 30-39, 41, 43 and 44;


2) Peptide Pool 2: SEQ ID NO: 47, 50-55, 59, 60, 62-64, 66-70, 72, 74-77, 79-81, 83, 84, 86, 87, 90-94, 96, 97, 99-101, 103, 110, 114-126, 129, 131-134, 135-138, 140, 144-146, 148, 149, 153-167, 294, 299, 300, 303, 308, 310, 311, 312, 317, 319, 320, 324, 325, 237, 333, 336 and 337, and optionally one or more peptides of SEQ ID NO: 235-283;


3) Peptide Pool 3: SEQ ID NO: 170, 172, 174-176, 178, 179, 181, 190, 341, 342 and 345-350, and optionally one or more peptides of SEQ ID NO: 284-289;


4) Vehicle control (negative control); and


5) Commercially available Candida albicans antigens (CANDIN®) (positive control).


The peptides are administered in a dose-escalating manner starting with a concentration of 0.05 μg peptide per 100 μL (dose strength “1×”) in phosphate buffered saline. If no adverse reaction is observed in the subjects after at least 1 hour, peptides at a concentration of 0.5 peptide per 100 μL (dose strength “10×”) are subsequently administered. The subjects are injected at pre-determined sites two inches apart from each other on the volar aspect of one forearm with a 0.1 mL 1× dose of each of the peptide pools, followed by the administration of a 0.1 mL 10× dose of each of the peptide pools, vehicle control (negative control), and commercially available Candida albicans antigens (CANDIN®) (positive control) at pre-determined sites on the volar aspect of the other forearm. Each subject will receive a total of 8 intradermal injections at least 2 inches apart.


During the Baseline/Screening Visit (Day 1, Visit 1) and prior to the scheduled injection administration, a general health inquiry (and a physical examination, if appropriate), adverse events (AEs), concomitant medications and pregnancy status is checked, and vital signs are taken. After the injection, subjects remain in the clinic for observation of potential injection site reactions or AEs for 60 minutes, and subsequently are able to leave if no safety concerns have been detected.


Delayed type hypersensitivity reactions are assessed after 48, 78 and 96 hours after administration.


Assessment of Anti-SARS-CoV-2 antibody titers are performed by enzyme-linked immunosorbent assay (ELISA). Flow cytometry is performed on PBMCs. For in vitro lymphocyte stimulation, the 3 test peptide mixtures are used along with commercially available benign (common cold) Coronavirus-specific peptides.


Skin test results are correlated with clinical history and laboratory findings and establish:


1. That the skin test identifies cell mediated immune responses to SARS-CoV-2.


2. The sensitivity and specificity of the test relative to clinical history and laboratory findings in acute, subacute, and convalescent subjects.


Subjects grade local and systemic skins reactions using a 7-point Likert Scale (Table 2). Adverse events categorized as systemic indicate whether 1) the adverse event does not interfere with the subject's routine activities, symptoms do not require therapy or medical evaluation and signs and symptoms are transient; 2) the adverse event interferes with the subject's daily routine but are usually improved by simple therapeutic measures, and usual routine activities can still be carried out; and 3) the adverse event results in the inability to perform routine activities and generally require systemic drug therapy or other treatment.

Primary Efficacy Endpoints of the study include area of induration at injection sites on the volar forearm. Secondary Efficacy Endpoints of the study include: 1. Anti-SARS-CoV-2 antibody titer (ELISA); and 2. Flow cytometry of PBMCs (e.g. SARS-CoV-2-specific T-cell responses are measured by stimulating PBMC in vitro with test peptides. A Th1 response is characterized by CD4+ T cells expressing IFN-γ and/or IL-2 and not IL-4, IL-5 and/or IL13; a Th2 response is measured by CD4+ T cells expressing IL-4, IL-5 and/or IL-13 and CD40L by 142 CD4+ T cells; a Th17 response is measured by CD4+ T cells expressing IL-17. SARS-CoV-2-specific CD8+ T cell responses is measured by the expression of IFN-γ and/or IL-2 cytokines). Optionally another pharmaceutically acceptable positive control can be used during flow cytometry analyes, e.g., a tetanus antigen).


Subjects will be monitored for safety for at least 6 months after the last investigational product exposure to include assessments of serious and other medically attended adverse events, and specifically COVID-19 diseases. Safety follow-up times include e.g. 1 month and 6 months, which may be conducted by telephone and/or in-person visits.


Example 5. Manufacturing Process

All investigational products are manufactured under current Good Manufacturing Practices (cGMP) by solid phase peptide synthesis (SPPS), employing Fmoc-amino acid chemistry. SPPS is a repetitive procedure, during which a peptide is assembled from the C-terminus to the N-terminus on a suitable resin (e.g. pre-loaded Wang polystyrene resin or Cl TCP (Cl) ProTide resin) as a solid support. In a first step, the C terminal Fmoc amino acid is coupled to the resin (only for Cys) all other syntheses are performed on pre-loaded Wang resins. Following deprotection of the Fmoc-protecting group by piperidine in dimethylformamide and subsequent washing to remove remaining piperidine, the next Fmoc amino acid is coupled to the resin using an activation reagent (e.g. diisopropyl carbodiimide) in the presence of ethyl (hydroximino) cyanoacetate (Oxyma). The process is continued using the subsequent sequence specific protected amino acids until the entire sequence has been built up. Side chain groups of the amino acid derivates are protected by acid labile protecting groups. The Fmoc cleavage and coupling steps are conducted on a Liberty PRIME peptide synthesizer from CEM. All coupling and deprotections are performed at elevated temperature with microwave radiation. Deprotection is conducted at about 110° C., coupling at approximately 105° C.


Upon completion, the resin-bound peptides are washed and dried. The individual peptides are cleaved from the resin by treatment of the resins with trifluoroacetic acid and scavengers. During this cleavage step, all remaining protecting groups are removed. Scavengers are added to prevent the reaction of reactive species formed during cleavage with the crude peptide. The crude peptide, which is now a trifluoroacetate salt, is subsequently precipitated using ethyl ether and dried in a vacuum oven.


Purification of the crude peptides is conducted by RP-HPLC using trifluoroacetic acid additive in the mobile phase (acetonitrile/water). Peptide fractions are collected and freeze dried.

Subjects are asked to return to the clinic for an in-person assessment of the skin test result at various time points, starting with 48 hours post kin test administration (e.g., Visit 3, Day 3), followed by two subsequent visits at 72 hours (e.g., Visit 4, Day 4) and 96 hours (e.g., Visit 5, Day 5) post skin test administration. Subjects have two telephone safety follow-up visits (e.g., Visit 6, Day 30 and Visit 7, Day 180). The duration of the study from pre-screening contact to the last safety monitoring is approximately 6 months.


Assessment of anti-SARS-CoV-2 antibody titers are performed for the detection and quantification of antibodies to SARS-CoV-2 (for e.g., by enzyme-linked immunosorbent assay (ELISA)). Flow cytometric analysis of SARS-CoV-2-specific T-cell responses are measured, along with in vitro positive controls (e.g., benign (common cold) Coronavirus-specific peptides). To characterize Th17 response, IL-17 is evaluated using an enzyme-linked immune absorbent spot assay (ELISpot). A T-MAP assay is performed to aid the identification of individuals with an adaptive T-cell immune response to SARS-CoV-2, which indicates recent or prior infection with SARS-CoV-2.


Additional in vitro positive controls that are tested include Candida albican peptides and a PepMix CEFX Ultra SuperStim Pool (PM-CEFX) containing tetanus, herpes simplex virus, human papillomavirus, measles, mumps, rubella, and polio peptides, are analyzed to confirm that subjects have intact T-cell immunity and are no immunodeficient.


Primary Efficacy Endpoint of the study includes maximal area of induration (e.g., >5 mm) at injection sites on the volar forearms at 48 hours, 72 hours and 96 hours post skin test administration. Secondary Efficacy Endpoints of the study include: 1) Correlation of the presence or absence of DTH reactions with clinical history to estimate sensitivity and specificity of the peptide pools as a marker of active or recovered infection relative to clinical history of infection; 2) Correlation of DTH reaction to adaptive T-cell immune response to SARS-CoV-2 assessed by immunoSEQ® T-MAP™ COVID; 3) Characterization of Th1 and Th2 responses to DTH reaction by measuring cytokine production and cell surface T-cell phenotype markers by intracellular cytokine staining; and 4) Characterization of Th17 response to DTH reaction by ELISpot. Exploratory efficacy endpoints include: 1) Correlation of DTH reaction with in vitro assays of immune response including anti-SARS-CoV-2 levels; 2) Correlation of DTH reaction with flow cytometry of PBMCs (e.g., SARS-CoV-2-specific T-cell responses); and 3) Comparison of DTH reactions in recovered subjects from SARS-CoV-2 infection (e.g., Cohort 2) with COVID-19 vaccine recipients (e.g., Cohort 3).

After Stage 1 administration, subjects are monitored for local site reactions and systemic adverse reactions for 60 minutes. At 30 minutes post administration, vital signs (e.g., systolic and diastolic blood pressure, heart rate, and temperature) are measured. If no systemic adverse reactions or unusual local site reactions are observed, the subjects will proceed to Stage 2 administration.


After Stage 2 administration, subjects will be monitored over the course of 30 minutes for unusual local site reactions and systemic adverse reactions. At 30 minutes post-administration, vital signs are assessed. If no evidence of systemic adverse reactions or unusual local site reactions occur, subjects are free to leave the clinic and are contacted 24 hours later for a brief telephone or in-person safety follow-up visit (e.g., Visit 2, Day 2). Subjects are instructed to keep the injection sites clean, uncovered, and to not scratch or rub the area. Subjects are asked to return to the clinic for an in-person assessment of the skin test result at various time points, starting with 48 hours post kin test administration (e.g., Visit 3, Day 3), followed by two subsequent visits at 72 hours (e.g., Visit 4, Day 4) and 96 hours (e.g., Visit 5, Day 5) post skin test administration. Subjects have two telephone safety follow-up visits (e.g., Visit 6, Day 30 and Visit 7, Day 180). The duration of the study from pre-screening contact to the last safety monitoring is approximately 6 months.


Assessment of anti-SARS-CoV-2 antibody titers are performed for the detection and quantification of antibodies to SARS-CoV-2 (for e.g., by enzyme-linked immunosorbent assay (ELISA)). Flow cytometric analysis of SARS-CoV-2-specific T-cell responses are measured, along with in vitro positive controls (e.g., benign (common cold) Coronavirus-specific peptides). To characterize Th17 response, IL-17 is evaluated using an enzyme-linked immune absorbent spot assay (ELISpot). A T-MAP assay is performed to aid the identification of individuals with an adaptive T-cell immune response to SARS-CoV-2, which indicates recent or prior infection with SARS-CoV-2.


Additional in vitro positive controls that are tested include Candida albican peptides and a PepMix CEFX Ultra SuperStim Pool (PM-CEFX) containing tetanus, herpes simplex virus, human papillomavirus, measles, mumps, rubella, and polio peptides, are analyzed to confirm that subjects have intact T-cell immunity and are no immunodeficient.


Primary Efficacy Endpoint of the study includes maximal area of induration (e.g., >5 mm) at injection sites on the volar forearms at 48 hours, 72 hours and 96 hours post skin test administration. Secondary Efficacy Endpoints of the study include: 1) Correlation of the presence or absence of DTH reactions with clinical history to estimate sensitivity and specificity of the peptide pools as a marker of active or recovered infection relative to clinical history of infection; 2) Correlation of DTH reaction to adaptive T-cell immune response to SARS-CoV-2 assessed by immunoSEQ® T-MAP™ COVID; 3) Characterization of Th1 and Th2 responses to DTH reaction by measuring cytokine production and cell surface T-cell phenotype markers by intracellular cytokine staining; and 4) Characterization of Th17 response to DTH reaction by ELISpot. Exploratory efficacy endpoints include: 1) Correlation of DTH reaction with in vitro assays of immune response including anti-SARS-CoV-2 levels; 2) Correlation of DTH reaction with flow cytometry of PBMCs (e.g., SARS-CoV-2-specific T-cell responses); and 3) Comparison of DTH reactions in recovered subjects from SARS-CoV-2 infection (e.g., Cohort 2) with COVID-19 vaccine recipients (e.g., Cohort 3).
