Definitions

  • the present invention relates to oligonucleotides having antiviral activities and their use as therapeutic agents in viral infections caused by human and animal viruses and in cancers caused by oncogene viruses and in other diseases whose etiology is viral-based.
  • viruses Many important infectious diseases afflicting centuries are caused by viruses. Many of these diseases, including rabies, smallpox, poliomyelitis, hepatitis, yellow fever, immune deficiencies and various encephalitic diseases, are frequently fatal. Others are significant in that they are highly contagious and create acute discomfort such as influenza, measles, mumps and chickenpox, as well as respiratory or gastrointestinal disorders. Others such as rubella and cytomegalovirus can cause congenital abnormalities. Finally there are viruses, known as oncoviruses, which can cause cancer in humans and animals.
  • Herpesviridae are a ubiquitous class of icoshedral, double stranded DNA viruses. Of over 100 characterized members of Herpesviridae (HHV), only eight infect humans. The best known among these are Herpes simplex type 1 (HSV-1), Herpes simplex type 2 (HSV-2), Varicella zoster (chicken pox or shingles), cytomegalovirus (CMV) and Epstein-Barr virus (EBV).
  • HSV-1 Herpes simplex type 1
  • HSV-2 Herpes simplex type 2
  • Varicella zoster chicken pox or shingles
  • CMV cytomegalovirus
  • EBV Epstein-Barr virus
  • the prevalence of Herpes viruses in humans is high, affecting at least one third of the worldwide population; and in the United States, 70-80% of the population have some kind of Herpes infection.
  • Herpes infections are usually not dangerous, as in the case of HSV-1 which usually only causes short lived lesions around the mouth and face, these viruses are also known to be the cause of more dangerous symptoms, which vary from genital ulcers and discharge to fetal infections which can lead to encephalitis (15% mortality) or disseminated infection (40% mortality).
  • Epstein-Barr virus is known to cause infectious mononucleosis in late childhood or adolescence or in young adults.
  • the hallmarks of acute infectious mononucleosis are sore throat, fever, headache, lymphadenopathy, enlarged tonsils and a typical, dividing lymphocytes in the peripheral blood.
  • Other manifestations frequently include mild hepatitis, splenomegaly and encephalitis.
  • EBV is also associated with two forms of cancer: Burkitt's lymphoma (BL) and the nasopharyngeal carcinoma (NPC).
  • BL Burkitt's lymphoma
  • NPC nasopharyngeal carcinoma
  • BL In endemic areas of equatorial Africa, BL is the most common childhood malignancy, accounting for approximately 80% of cancers in children. While moderately observed in North American Caucasians, NPC is one of the most common cancers in Southern China with age incidence of 25 to 55 years. EBV, like the cytomegalovirus, is also associated with post-transplant lymphoproliferative disease, which is a potentially fatal complication of chronic immunosuppression following solid organ or bone marrow transplantation.
  • HSV hypertension
  • skin and eye infections for example, chorioretinitis or keratoconjunctivitis.
  • chorioretinitis or keratoconjunctivitis Approximately 300,000 cases of HSV infections of the eye are diagnosed yearly in the United States.
  • HIV human immunodeficiency virus
  • HAART Highly Active AntiRetroviral Treatment
  • HAART therapies typically comprise two nucleoside reverse transcriptase inhibitors drugs with a third drug, either a protease inhibitor or a non-nucleoside reverse transcriptase inhibitor.
  • Clinical studies have shown that HAART is the most effective means of reducing viral loads and minimizing the likelihood of drug resistance.
  • HAART has been shown to reduce the amount of HIV in the body, commonly known as viral load
  • tens of thousands of patients encounter significant problems with this therapy.
  • Some side effects are serious and include abnormal fat metabolism, kidney stones, and heart disease.
  • Other side effects such as nausea, vomiting, and insomnia are less serious, but still problematic for HIV patients that need chronic drug therapy for a lifetime.
  • Respiratory syncytial virus causes upper and lower respiratory tract infections. It is a negative-sense, enveloped RNA virus and is highly infectious. It commonly affects young children and is the most common cause of lower respiratory tract illness in infants. RSV infections are usually associated with moderate-to-severe cold-like symptoms. However, severe lower respiratory tract disease may occur at any age, especially in elderly or immunocompromised patients. Children With severe infections may require oxygen therapy and, in certain cases, mechanical ventilation. According to the American Medical Association, an increasing number of children are being hospitalized for bronchiolitis, often caused by RSV infection. RSV infections also account for approximately one-third of community-associated respiratory virus infections in patients in bone marrow transplant centers. In the elderly population, RSV infection has been recently recognized to be very similar in severity to influenza virus infection.
  • Influenza also known as the flu, is a contagious disease that is caused by the influenza virus. It attacks the respiratory tract in humans (nose, throat, and lungs). An average of about 36,000 people per year in the United States die from influenza, and 114,000 per year require hospitalization as a result of influenza.
  • herpes viruses In all infectious diseases, the efficacy of a given therapy often depends on the host immune response. This is particularly true for herpes viruses, where the ability of all herpes viruses to establish latent infections results in an extremely high incidence of reactivated infections in immunocompromised patients. In renal transplant recipients, 40% to 70% reactivate latent HSV infections, and 80% to 100% reactivate CMV infections. Such viral reactivations have also been observed with AIDS patients.
  • the hepatitis B virus is a DNA virus that belongs to the Hepadnaviridae family of viruses. HBV causes hepatitis B in humans. It is estimated that 2 billion people have been infected (1 out of 3 people) in the world. About 350 million people remain chronically infected and an estimated 1 million people die each year from hepatitis B and its complications. HBV can cause lifelong infection, cirrhosis of the liver, liver cancer, liver failure, and death. The virus is transmitted through blood and bodily fluids. This can occur through direct blood-to-blood contact, unprotected sex, use of unsterile needles, and from an infected woman to her newborn during the delivery process.
  • HCV infection is the most common chronic bloodborne infection in the United States where the number of infected patients likely exceeds 4 million. This common viral infection is a leading cause of cirrhosis and liver cancer, and is now the leading reason for liver transplantation in the United States. Recovery from infection is uncommon, and about 85 percent of infected patients become chronic carriers of the virus and 10 to 20 percent develop cirrhosis. It is estimated that there are currently 170 million people worldwide who are chronic carriers. According to the Centers for Disease Control and Prevention, chronic hepatitis C causes between 8,000 and 10,000 deaths and leads to about 1,000 liver transplants in the United States alone each year. There is no vaccine available for hepatitis C. Prolonged therapy with interferon alpha, or the combination of interferon with Ribavirin, is effective in only about 40 percent of patients and causes significant side effects.
  • herpesviridae there are five major treatments currently approved for use in the clinic: idoxuridine, vidarabine, acyclovir, foscarnet and ganciclovir. While having limited efficacy, these treatments are also fraught with side effects. Allergic reactions have been reported in 35% of patients treated with idoxuridine, vidarabine can result in gastrointestional disturbances in 15% of patients and acyclovir, foscarnet and ganciclovir, being nucleoside analogs, affect DNA replication in host cells. In the case of ganciclovir, neutropenia and thrombocytopenia are reported in 40% of AIDS patients treated with this drug.
  • Ribavirin The treatment of RSV infections in young infants is another example of the urgent need for new drug development.
  • the usual line of treatment is to deliver Ribavirin by inhalation using a small-particule aerosol in an isolation tent.
  • Ribavirin only mildly effective, but its uses is associated with significant side effects.
  • the potential release of the drug has caused great concern in hospital personnel because of the known teratogenicity of Ribavirin.
  • Zamecnik et al. have used ONs specifically targeted to the reverse transcriptase primer site and to splice donor/acceptor sites (Zamecnik, et al (1986) Proc. Natl. Acad. Sci. USA 83:4143-) (Goodchild & Zamecnik (1989) U.S. Pat. No. 4,806,463).
  • Crooke and coworkers (Crooke et al. (1992) Antimicrob. Agents Chemother. 36:527-532) described an antisense against HSV-1.
  • Draper et al. (1993) (U.S. Pat. No. 5,248,670) have reported antisense oligonucleotides having anti-HSV activity containing the Cat sequence and hybridizing to the HSV-1 genes UL13, UL39 and UL40.

Nos. 5,264,423 and 5,276,019) described the inhibition of replication of HIV, and more particularly to PS-ODN analogs that can be used to prevent replication of foreign nucleic acids in the presence of normal living cells. Cohen et al describe antiviral activity of antisense PS-ODNs specific to a viral sequence. They also describe testing polyA, polyT and polyC PS-ODN sequences of 14, 18, 21 and 28-mers and indicate an antiviral effect of those PS-ODNs.
  • Gao et al (Gao et al (1989) J Biol Chem 264 :11521-11526), describe the inhibition of replication of HSV-2, by PS-ODNs by testing of polyA, polyT and polyC PS-ODN sequences in sizes of 7, 15, 21 and 28 nucleotides.
  • Feng at al. (Feng et al. (2002) J. Virol. 76 :11757-11762) described A(n) and TG(n) PO-ODNs binding to the recombinant HIV nucleocapsid but with no data nor references to an anti-HIV activity.
  • Antisense ODNs developed as anticancer agents, antiviral agents, or to treat others diseases are typically approximately 20 nucleotides in length.
  • the length of an antisense oligonucleotide must be optimized: If the antisense oligonucleotide is either too long or too short, an element of specificity is lost. At the present time, the optimal length for an antisense oligonucleotide seems to be roughly 16-20 nucleotides”.

This term includes oligonucleotides composed of naturally-occurring nucleobases, sugars and covalent internucleoside (backbone) linkages as well as oligonucleotides having non-naturally-occurring portions which function similarly.
  • modified or substituted oligonucleotides are often preferred over native forms because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for nucleic acid target and increased stability in the presence of nucleases. Examples of modifications that can be used are described herein. Oligonucleotides that include backbone and/or other modifications can also be referred to as oligonucleosides.
  • the phrase “adapted for use as an antiviral agent” indicates that the material exhibits an antiviral effect and does not include any component or material that makes it unsuitable for use in inhibiting viral production in an in vivo system, e.g., for administering to a subject such as a human subject.
  • non-sequence complementary mode of action indicates that the mechanism by which the material exhibits an antiviral effect is not due to hybridization of complementary nucleic acid sequences, e.g., an antisense effect.

  • the present invention is concerned with the identification and use of antiviral oligonucleotides that act by a non-sequence complementary mechanism, and includes the discovery that for many viruses, the antiviral activity is greater for larger oligonucleotides, and are typically optimal for oligonucleotides that are 40 nucleotides or more in length.
  • antisense oligonucleotides As described in the Background, a number of antisense oligonucleotides (ONs) have been tested for antiviral activity. However, such antisense ONs are sequence-specific, and typically are about 16-20 nucleotides in length.
  • the antiviral effect of random PS-ODNs is not sequence specific. Considering the volumes and concentrations of PS-ODNs used in those tests, it is almost theoretically impossible that a particular random sequence is present at more than 1 copy in the mixture. This means than there can be no antisense effect in these PS-ODNs randomers. In the latter example, should the antiviral effect be caused by the sequence-specificity of the PS-ODNs, such effect would thus have to be caused by only one molecule, a result that does not appear possible. For example, for an ON randomer 40 bases in length, any particular sequence in the population would theoretically represent only 1 ⁇ 4 40 or 8.27 ⁇ 10 ⁇ 25 of the total fraction.
  • randomers may block viral replication by several mechanisms, including but not limited to the following: 1. preventing the adsorption or receptor interaction of virions, thus preventing infection, 2. doping the virus assembly or the packaging of viral genomes into capsids (competing with viral DNA or RNA for packaging), resulting in defective virions, 3. disrupting and or preventing the formation of capsids during packaging or the interaction of capsid proteins with other structural proteins, resulting in inhibition of viral release or causing the release of defective virions, 4. binding to key viral components and preventing or reducing their activity, 5. binding to key host components required for viral proliferation.
  • ONs against viral replication Without being limited on the mechanism by which the present viral inhibition is achieved, as indicated above there are several possible mechanisms that could explain and/or predict the inhibitory properties of ONs against viral replication. The first of these is that the general aptameric effect of ONs is allowing for their attachment, either to proteins on the cell surface or to viral proteins, preventing viral adsorption and fusion. The size threshold for effect may be a result of a certain cumulative charge required for interaction.
  • ONs may function within the cell by preventing packaging and/or assembly of the virus. ONs above a certain size threshold may compete or interfere with the normal capsid/nucleic acid interaction, preventing the packaging of a functional viral genome inside new viruses. Alternatively, ONs may prevent the formation of a normal capsid, which could prevent normal viral budding, alter viral stability, or prevent proper virion disassembly upon internalization.
  • ONs in accordance with the present invention could thus be used for treating or preventing viral infection.
  • the viral infections treated could be those caused by human, animal, and plant viruses
  • an oligo delivery system such as DOTAP, lipofectamine or oligofectamine could result in much greater efficacies, especially with the larger ( ⁇ 40 bases) randomers.
  • HSV and CMV are both double-stranded DNA viruses of the herpesviridae family
  • HIV is a RNA virus from the retroviridae
  • RSV a RNA virus from the paramyxoviridae.
  • ON randomers can inhibit viral function in a variety of different viruses, without being limited to the mechanisms listed, as discussed above the following mechanisms are reasonable: A) ONs/ON randomers are inhibiting viral infection via an aptameric effect, preventing viral fusion with the plasma membrane; and/or B) ONs/ON randomers are preventing or doping the assembly of virions or the packaging of viral DNA within capsids resulting in defective virions; and/or C)ONs/ON randomers are interfering with host proteins or components required in the assembly and/or packaging and/or gene expression of the virus.

  • Compound REP 2026 showed an antiviral activity while having a central portion comprising unmodified PO-nucleotides and 4 methylphosphonate linkages at both termini protecting from degradation. This indicates that PO-ODNs can be used as antivirals while protected from degradation. This protection can be achieved by modifying nucleotides at termini and/or by using a suitable delivery system as described later.
  • the sequence composition of the DNA used has little effect on the overall efficacy, whether randomer, random sequence or a specific HSV-1 sequence.
  • HSV-1 sequence was almost 3 ⁇ more potent than a random sequence (see FIG. 10).
  • the non-antisense mechanism non-sequence complementary mechanism elucidated herein may represent the predominant part of this activity. Indeed, as the ON grows to 40 bases, essentially all of the antiviral activity can be attributed to a non-antisense effect.
  • One goal of using an ON randomer is to lower the toxicity. It is known that different sequences may trigger different responses in the animal, such as general toxicity, interaction with serum proteins, and interaction with immune system (Monteith et al (1998) Toxicol Sci 46:365-375). The mixture of ONs may thus decrease toxic effects because the level of any particular sequence will be very low, so that no significant interaction due to sequence or nucleotide composition is likely.

This characteristic of antiviral polymers can be useful in competing with ONs for the binding, or adsorption to the virion, the result being an increased intracellular activity of the ONs compared to its extracellular activity.

  • One method for purifying a high affinity ON, or a plurality of high affinity ONs involves using a stationary phase medium with bound viral protein(s) as an affinity matrix to bind ONs, which can then be eluted under increasingly stringent conditions (e.g., increasing concentration of salt or other chaotropic agent, and/or increasing temperture and/or changes in pH).
  • a method can, for example, be carried out by:
  • a method derived and modified from the SELEX methodology can be used for purifying the high affinity ON.
  • One implementation of such a method can be performed as:
  • a starting ON pool material for example, a collection of synthetic random ONs containing a high number of sequences, e.g., one hundred trillion (1014) to ten quadrillion (1016) different sequences.
  • Each ON molecule contains a segment of random sequence flanked by primer-binding sequences at each end to facilitate polymerase chain reaction (PCR). Because the nucleotide sequences of essentially all of the molecules are unique, an enormous number of structures are sampled in the population. These structures determine each molecule's biochemical properties, such as the ability to bind a given viral target molecule;
  • steps (b) (c) and (d) can be performed multiple times (i.e., multiple cycles or rounds of enrichment and amplification) in order to preferentially recover ONs that display the highest binding affinity to viral protein(s). After several cycles of enrichment and amplification, the population is dominated by sequences that display the desired biochemical property;
  • Another approach is to apply a modification of a split synthesis methodology to create one-bead one-PS-ODN and one-bead one-PS2—ODN libraries as described in Yang et al (2002) Nucl. Acids Res. 30(e132):1-8. Binding and selection of specific beads to viral proteins can be done. Sequencing both the nucleic acid bases and the positions of any thioate/dithioate linkages can be carried out by using a PCR-based identification tag of the selected beads. This approach can allow for the rapid and convenient identification of PS-ODNs or PS2-ODNs that bind to viral proteins and that exhibit potent antiviral properties.
  • one or more such high affinity sequences can be selected and synthesized (e.g., by either chemical or enzymatic synthesis) to provide a preparation of high affinity ON(s), which can be modified to improve their activity, including improving their pharmacokinetic properties.
  • high affinity ONs can be used in the present invention.
  • Another approach is used in an alternative embodiment of the present invention for the treatment, the control of the progression, or the prevention of prion disease.
  • This fatal neurodegenerative disease is infectious and can affect both humans and animals.
  • Structural changes in the cellular prion protein, PrPC to its scrapie isoform, PrPSC, are considered to be the obligatory step in the occurrence and propagation of the prion disease.
  • Amyloid polymers are associated with neuropathology of the prion disease.
  • ONs having affinity to proteins such as phosphorothioates are used to compete or inhibit the interaction of double stranded nucleic acid with the PrPC and consequently stop the formation of the amyloid polymers.
  • ONs of different sizes and different compositions can be used in an appropriate delivery form to treat patients suffering from prion diseases or for prophylaxis in high risk situations.
  • Such interfering ONs can be identified by measuring folding changes of amyloid polymerase as described by Nandi et al. (supra) in the presence of test ONs.
  • Viruses are putative causal agents in diseases and conditions that are not related to a primary viral infection. For example, arthritis is associated with HCV (Olivieri et al. (2003) Rheum Dis Clin North Am 29:111-122), Parvovirus B19, HIV, HSV, CMV, EBV, and VZV (Stahl et al. (2000) Clin Rheumatol 19:281-286). Other viruses have also been identified as playing a role in different diseases. For example, influenza A in Parkinson's disease (Takahashi et al.

  • Another modification includes phosphorodithioate linkages. Knowing that phosphorodithioate ODNs (PS2-ODNs) and PS-ODNs have a similar binding affinity to proteins (Tonkinson et al. (1994) Antisense Res. Dev. 4:269-278)(Cheng et al. (1997) J. Mol. Recogn. 10:101-107) and knowing that a possible mechanism of action of ODNs is binding to viral proteins, it could be desirable to include phosphorodithioate linkages on the antiviral ODNs described in this invention.
  • ODNs prepared by conventional methods consist of a mixture of diastereomers by virtue of the asymmetry around the phosphorus atom involved in the internucleotide linkage. This may affect the stability of the binding between ODNs and viral components such as viral proteins. Previous data showed that protein binding is significantly stereo-dependent (Yu et al.). Thus, using stereodefined or stereo-enriched ODNs could improve their protein binding properties and improve their antiviral efficacy.

Either of the phases of the emulsion may be a semisolid or a solid, as is the case of emulsion-style ointment bases and creams. Other means of stabilizing emulsions entail the use of emulsifiers that may be incorporated into either phase of the emulsion.
  • Emulsifiers may broadly be classified into four categories: synthetic surfactants, naturally occurring emulsifiers, absorption bases, and finely dispersed solids (Idson, in Pharmaceutical Dosage Forms , Lieberman, Rieger and Banker (Eds.), 1988, Marcel Dekker, Inc., New York, N.Y., volume 1, p. 199).

  • Naturally occurring emulsifiers used in emulsion formulations include lanolin, beeswax, phosphatides, lecithin and acacia.
  • Absorption bases possess hydrophilic properties such that they can soak up water to form w/o emulsions yet retain their semisolid consistencies, such as anhydrous lanolin and hydrophilic petrolatum. Finely divided solids have also been used as good emulsifiers especially in combination with surfactants and in viscous preparations.

  • microemulsions offer the advantage of solubilizing water-insoluble drugs in a formulation of thermodynamically stable droplets that are formed spontaneously.
  • Surfactants used in the preparation of microemulsions include, but are not limited to, ionic surfactants, non-ionic surfactants, Brij 96, polyoxyethylene oleyl ethers, polyglycerol fatty acid esters, tetraglycerol monolaurate (ML310), tetraglycerol monooleate (MO310), hexaglycerol monooleate (PO310), hexaglycerol pentaoleate (PO500), decaglycerol monocaprate (MCA750), decaglycerol monooleate (MO750), decaglycerol sequioleate (S0750), decaglycerol decaoleate (DA0750), alone or in combination with cosurfactants.

  • polyglycerol fatty acid esters tetraglycerol monolaurate (ML310
  • the cosurfactant usually a short-chain alcohol such as ethanol, 1-propanol, and 1-butanol, serves to increase the interfacial fluidity by penetrating into the surfactant film and consequently creating a disordered film because of the void space generated among surfactant molecules.
  • Microemulsions may, however, be prepared without the use of cosurfactants and alcohol-free self-emulsifying microemulsion systems are known in the art.
  • the aqueous phase may typically be, but is not limited to, water, an aqueous solution of the drug, glycerol, PEG300, PEG400, polyglycerols, propylene glycols, and derivatives of ethylene glycol.

  • Microemulsions are particularly of interest from the standpoint of drug solubilization and the enhanced absorption of drugs.
  • Lipid based microemulsions both o/w and w/o have been proposed to enhance the oral bioavailability of drugs, including peptides (Constantinides et al., Pharmaceutical Research, 1994,11,1385-1390; Ritschet, Met/i. Find. Exp. Clin. PharmacoL, 1993, 13, 205).
  • Micro-emulsions afford advantages of improved drug solubilization, protection of drug from enzymatic hydrolysis, possible enhancement of drug absorption due to surfactant-induced alterations in membrane fluidity and permeability, ease of preparation, ease of oral administration over solid dosage forms, improved clinical potency, and decreased toxicity (Constantinides et at., Pharmaceutical Research, 1994,11, 1385; Ho et al., J. Pharm. Set, 1996, 85,138-143). Often microemulsions may form spontaneously when their components are brought together at ambient temperature. This may be particularly advantageous when formulating thermolabile drugs, peptides or oligonucleotides. Microemulsions have also been effective in the transdermal delivery of active components in both cosmetic and pharmaceutical applications.
  • microemulsion compositions and formulations of the present invention will facilitate the increased systemic absorption of oligonucteotides and nucleic acids from the gastrointestinal tract, as well as improve the local cellular uptake of oligonucleotides and nucleic acids within the gastrointestinal tract, vagina, buccal cavity and other areas of administration.
  • Microemulsions of the present invention may also contain additional components and additives such as sorbitan monostearate (Grill 3), Labrasol, and penetration enhancers to improve the properties of the formulation and to enhance the absorption of the oligonucleotides and nucleic acids of the present invention.
  • Penetration enhancers used in the microemulsions of the present invention may be classified as belonging to one of five broad categories-surfactants, fatty acids, bile salts, chelating agents, and non-chelating non-surfactants (Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, p. 92).
  • liposome refers to a vesicle composed of amphiphilic lipids arranged in a spherical bilayer or bilayers, i.e., liposomes are unilamellar or multilamellar vesicles which have a membrane formed from a lipophilic material and an aqueous interior.
  • the aqueous portion typically contains the composition to be delivered.
  • lipid vesicles In order to cross intact mammalian skin, lipid vesicles must pass through a series of fine pores, each with a diameter less than 50 nm, under the influence of a suitable transdermal gradient. Therefore, it is desirable to use a liposome which is highly deformable and able to pass through such fine pores. Additional factors for liposomes include the lipid surface charge, and the aqueous volume of the liposomes.
  • liposomes obtained from natural phospholipids are biocompatible and biodegradable; liposomes can incorporate a wide range of water and lipid soluble drugs; liposomes can protect encapsulated drugs in their internal compartments from metabolism and degradation (Rosoff, in Pharmaceutical Dosage Forms , Lieberman, Rieger and Banker (Eds.), 1988, Marcel Dekker, Inc., New York, N.Y., volume 1, p. 245).
  • liposomes present several advantages over other formulations. Such advantages include reduced side-effects related to high systemic absorption of the administered drug, increased accumulation of the administered drug at the desired target, and the ability to administer a wide variety of drugs, both hydrophilic and hydrophobic, into the skin.
  • Compounds including analgesics, antibodies, hormones and high-molecular weight DNAs have been administered to the skin, generally resulting in targeting of the upper epidermis.
  • Liposomes fall into two broad classes. Cationic liposomes are positively charged liposomes which interact with the negatively charged DNA molecules to form a stable complex. The positively charged DNA/liposome complex binds to the negatively charged cell surface and is internalized in an endosome. Due to the acidic pH within the endosome, the liposomes are ruptured, releasing their contents into the cell cytoplasm (Wang et at., Biochem. Biophys. Res. Commun., 1987,147,980-985).
  • Liposomes which are pH-sensitive or negatively-charged, entrap DNA rather than complex with it. Since both the DNA and the lipid are similarly charged, repulsion rather than complex formation occurs. The DNA is thus entrapped in the aqueous interior of these liposomes. pH-sensitive liposomes have been used, for example, to deliver DNA encoding the thymidine kinase gene to cell monolayers in culture (Zhou et al., Journal of Controlled Release, 1992, 19, 269-274).
  • liposomal composition includes phospholipids other than naturally-derived phosphatidylcholine.
  • Neutral liposome compositions can be formed from dimyristoyl phosphatidylcholine (DMPC) or dipalmitoyl phosphatidylcholine (DPPC).
  • Anionic liposome compositions generally are formed from dimyristoyl phosphatidylglycerol, while anionic fusogenic liposomes are formed primarily from dioleoyl phosphatidylethanolamine (DOPE).
  • DOPE dioleoyl phosphatidylethanolamine
  • Another type of liposomal composition is formed from phosphatidylcholine (PC) such as, for example, soybean PC, and egg PC.
  • PC phosphatidylcholine
  • Another type is formed from mixtures of phospholipid and/or phosphatidylcholine and/or cholesterol.
  • Non-ionic liposomal systems have also been examined to determine their utility in the delivery of drugs to the skin, in particular systems comprising non-ionic surfactant and cholesterol.
  • Non-ionic liposomal formulations comprising NovasoneTMI (glyceryl dilaurate/cholesterol/polyoxyethylene-10-stearyl ether) and NovasomeTMII (glyceryl distearate/cholesterol/polyoxyethylene-10-stearyl ether) were used to deliver cyclosporin-A into the dermis of mouse skin. Results indicated that such non-ionic liposomal systems were effective in facilitating the deposition of cyclosporin-A into different layers of the skin (Hu et at. S.T.P. Pharma. Sci., 1994, 4, 6, 466).
  • Liposomes also include “sterically stabilized” liposomes, a term which, as used herein, refers to liposomes comprising one or more specialized lipids that, when incorporated into liposomes, result in enhanced circulation lifetimes relative to liposomes lacking such specialized lipids.
  • sterically stabilized liposomes are those in which part of the vesicle-forming lipid portion of the liposome include one or more glycolipids, such as monosialoganglioside G MI , or is derivatized with one or more hydrophilic polymers, such as a polyethylene glycol (PEG) moiety.

No. 5,665,710 (methods of encapsulating oligodeoxynucleotides in liposomes); Love et al., WO 97/04787 (liposomes that include antisense oligonucleotides).
  • Transfersomes are highly deformable lipid aggregates which are attractive for drug delivery vehicles.
  • Transfersomes may be described as lipid droplets which are so highly deformable that they can penetrate through pores which are smaller than the droplet.
  • Transfersomes are adaptable to the environment in which they are used, for example, they are shape adaptive, self-repairing, frequently reach their targets without fragmenting, and often self-loading. Transfersomes can be made, for example, by adding surface edge-activators, usually surfactants, to a standard liposomal composition.

  • penetration enhancers are used in or with a composition to increase the delivery of nucleic acids, particularly oligonucleotides, to the skin of animals.
  • nucleic acids particularly oligonucleotides
  • Most drugs are present in solution in both ionized and nonionized forms. However, usually only lipid soluble or lipophilic drugs readily cross cell membranes. It has been discovered that even non-lipophilic drugs may cross cell membranes if the membrane to be crossed is treated with a penetration enhancer. In addition to aiding the diffusion of non-lipophilic drugs across cell membranes, penetration enhancers also enhance the permeability of lipophilic drugs.
  • Penetration enhancers may be classified as belonging to one of five broad categories, i.e., surfactants, fatty acids, bile salts, chelating agents, and non-chelating nonsurfactants (Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, p.92). Each of these classes of penetration enhancers is described below in greater detail.

  • chelating agents can be regarded as compounds that remove metallic ions from solution by forming complexes therewith, with the result that absorption of oligonucleotides through the mucosa is enhanced.
  • chelating agents have the added advantage of also serving as DNase inhibitors, as most characterized DNA nucleases require a divalent metal ion for catalysis and are thus inhibited by chelating agents (Jarrett, J. Chromatogr., 1993, 618, 315-339).
  • chelating agents include disodium ethylenediaminetetraacetate (EDTA), citric acid, salicylates (e.g., sodium salicylate, 5-methoxysalicylate and homovanilate), N-acyl derivatives of collagen, laureth-9 and N-amino acyl derivatives of beta-diketones (enamines)(Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, page 92; Muranishi, Critical Reviews in Therapeutic Drug Carrier Systems, 1990, 7,1-33; Buur et al., J.

  • An ON, e.g., ODN, in question shall be considered to be acting predominantly by a non-sequence complementary mode of action if it meets the criterion of any one of the 3 tests outlined below.
  • Test #1 Effect of Partial Degeneracy on Antiviral Efficacy
  • L ON the number of bases in the original ON
  • X the number of bases on each end of the oligo to be made degenerate (but having the same chemistry as the original ON)
  • Each degenerate base shall be synthesized according to any suitable methodology, e.g., the methodology described herein for the synthesis of PS-ODN randomers.
  • the ON is claimed to have an anti-viral activity against a member of the herpesviridae, retroviridae, or paramyxoviridae families
  • the IC 50 generation will be performed using the assay described herein for that viral family preferably using the viral strains indicated. If the ON is claimed to have an anti-viral activity against a member of a particular virus family not mentioned above, then the IC50 values shall be generated by a test of antiviral efficacy accepted by the pharmaceutical industry. IC50 values shall be generated using a minimum of seven concentrations of compound, with three or more points in the linear range of the dose response curve. Using this test, the IC 50 of said ON shall be compared to its degenerate counterpart.
  • the ON shall be deemed to be functioning predominantly by a non-sequence complementary mode of action.
  • Test #2 Comparison of Efficacy With Randomer
  • This test serves to compare the anti-viral efficacy of an ON with the antiviral efficacy of a randomer ON of equivalent size and the same chemistry in the same virus or viral family.
  • the ON is claimed to have an anti-viral activity against a member of the herpesviridae, retroviridae, or paramyxoviridae families
  • the IC 50 generation will be performed using the assay described herein for that viral family preferably using the viral strains indicated. If the ON is claimed to have an anti-viral activity against a member of a particular virus family not mentioned above, then the IC50 values shall be generated by a test of antiviral efficacy accepted by the pharmaceutical industry. IC50 values shall be generated using a minimum of seven concentrations of compound, with three or more points in the linear range of the dose response curve. Using this test, the IC 50 of the ON shall be compared to an ON randomer of equivalent size and the same chemistry.
  • the ON shall be deemed to be functioning predominantly by a non-sequence complementary mode of action.
  • Test #3 Comparison of Efficacy in a Different Viral Family
  • This test serves to compare the efficacy of an ON against a target virus whose genome is homologous to the ON with the efficacy of the ON against a second virus whose genome has no homology to ON.
  • the different virus will be selected from a different viral family than the viral family of the target virus.
  • the comparison of the relative activities of the ON in the target virus and the second virus is accomplished by using the activities of a randomer of the same length and chemistry in the both viruses to normalize the IC 50 values for the ON obtained in the two viruses.
  • the ON is claimed to have an anti-viral activity against a certain virus
  • the IC 50 generation will be determined in this virus using one of the assays described herein for the herpesviridae, retroviridae, or paramyxoviridae families, or other assay known in the art.
  • IC 50 generation will be performed for the ON against a second virus using one of the assays as described herein for a virus whose genome has no homology to the sequence of the ON.
  • IC 50 generation is also performed for a randomer of equivalent size and chemistry against each of the viruses.
  • the IC 50 efficacies of the randomer against the two viruses are used to normalize the IC 50 values for the specific ON as follows:
  • the fold difference in the IC50s for the ON in the homologus versus the non-homologous virus is calculated by dividing the transformed IC50 of the ON in the non-homologous virus by the transformed IC50 of the ON in the homologous virus.
  • the ON shall be deemed to be acting by a non-sequence complementary mode of action if the fold difference is less than 2.
  • the ON shall be deemed to be acting by a non-sequence complimentary mode of action if the fold difference in less than 10.
  • Test #4 Efficacy in a Different Viral Family
  • This test serves to determine if an ON has a drug like activity in a virus where the sequence of said ON is not homologous to any portion of the viral genome.
  • the ON shall be tested using one of the assays described herein for the herpesviridae, retroviridae or paramyxoviridae such that the sequence of the ON tested is not homologous to any portion of the genome of the virus to be used.
  • An IC 50 value shall be generated using a minimum of seven concentrations of the ON, with three or more points in the linear range.
  • the ON shall be deemed to have a drug like activity. If the ON is deemed to have a drug like activity in a virus to which the ON is not complementary and thus can have no complementary sequence dependent activity, it shall be considered to be acting by a non-sequence complementary mode of action.
  • the ON must have an antiviral activity which is at least 10-fold (1 log) greater than a randomer or a degenerate ON of the same chemistry to be considered to be acting by an antisense mechanism.
  • Our rationale for this larger threshold it that, given the current state of the art for ON design for antisense, it is reasonable to assume that oligos that are 26 bases and larger and claimed to have an antiviral activity were designed with the knowledge of the invention contained herein (the optimal length of antisense ONs is generally accepted to be between 16 and 21 bases).
  • the thresholds described in tests 1 to 3 above are the default thresholds. If specifically indicated, other thresholds can be used in the comparison tests 1 to 3 described above. Thus for example, for ONs under 25 bases in length and/or ONs 25 or more bases in length, if specifically indicated the threshold for determining whether an ON is acting principally by a non-sequence complementary mode of action can be any of 10-fold, 8-fold, 6-fold, 5-fold, 4-fold, 3-fold, 2-fold, 1.5-fold, or equal.
  • the threshold described in test 4 above is also a default threshold.
  • the threshold for determining whether an ON is acting principally by a non-sequence complementary mode of action in test 4 can be an IC 50 of less than 1 uM, 0.8 uM, 0.6 uM, 0.5 uM, 0.4 uM, 0.3 uM, 0.2 uM or 0.1 uM.
  • the ON can be required to satisfy any two (e.g., tests 1 & 2, 1 & 3, 1 & 4, 2 & 3, 2& 4 and 3 & 4) or any three (e.g., tests 1 & 2 & 3, 1 & 3 & 4, and 2 & 3 & 4) or all 4 of the tests at a default threshold, or if specifically indicated, at another threshold as indicated above.
  • a plaque reduction assay performed as follows:
  • HSV-1 or HSV-2 VERO cells (ATCC# CCL-81) are grown to confluence in 12 well tissue culture plates (NUNC or equivalent) at 37 deg C. and 5% CO 2 in the presence of MEM supplemented with 10% heat inactivated fetal calf serum and gentamycin, vancomycin and amphoterecin B. Upon reaching confluency, the media is changed to contain 5% fetal calf serum and antibiotics as detailed above supplemented with either HSV-1 (strain KOS, 40-60 PFU total) or HSV-2 (strain MS2, 40-60 PFU total).
  • Viral adsorbtion proceeds for 90 minutes, after which cells are washed and replaced with new “overlay” media containing 5% fetal calf serum and 1% human imunoglobins. Three to four days after adsorbtion, cells are fixed by formalin and plaques are counted following formalin fixation.
  • CMV strain AD169, 40-60 PFU total
  • testing is to be conducted in a plaque assay described above using an appropriate cellular host and 40-60 PFU of virus during the adsorbtion.
  • IC 50 is the concentration at which 50% of the plaques are present compared to the untreated control.
  • Compound to be tested is present during the adsorption and in the overlay.
  • Human PBMCs are infected with a primary isolate of HIV-1 in the presence the compound. The cells are then incubated for an additional 7 days in fresh medium supplemented with the compound after which the levels of p24 in the supernatant are measured using a commercial p24 ELISA kit (BIOMERIEUX or equivalent.)
  • IC 50 is the concentration at which the amount of p24 detectable is 50% of the p24 present in the untreated control.
  • Compound to be tested is present during the adsorption and in the media after adsorption.
  • Hep2 cells were plated in 96 well plates and allowed to grow overnight in MEM plus 5% fetal calf serum at 37 deg C. and 5% CO 2 . The next day, cells are infected with RSV (strain A2, 10 8.2 TCID 50 /ml in 100 ul/well) by adsorbtion for 2 hours. Following adsorbtion, media is changed and after 7 days growth, CPE is measured by conversion of Alamar Blue dye to its fluorescent adduct by living cells.
  • RSV strain A2, 10 8.2 TCID 50 /ml in 100 ul/well
