1 FIELD OF THE INVENTION

[0002] The present invention is directed to methods for the use of 5 '-adenosine diphosphate ribose (ADPR), and compositions thereof, for treating, managing, or preventing adenovirus- related diseases or conditions, eye disorders, cancer, or diseases or conditions caused by infection, inflammation, or physical, chemical, thermal, or radiation injuries.

2 BACKGROUND OF THE INVENTION

[0003] Human adenoviruses have been well established as infectious agents in both immunocompetent as well as immunocompromised individuals. Human adenovirus infections have been shown to be the cause of high morbidity and mortality in immunocompromised individuals. Despite their life-threatening nature, there are currently no approved antiviral therapies for human adenovirus infections (see Lion, 2014, "Adenovirus Infections in

Immunocompetent and Immunocompromised Patients," Clin. Microbiol. Rev., 27(3):441-462; Martinez-Aguado et al., 2015 "Antiadenovirus Drug Discovery: Potential Targets and Evaluation Methodologies," Drug Discov. Today, 20(10): 1235-1242. Broadly acting antiviral drugs such as cidofovir, ribavirin, and ganciclovir are some of the suboptimal therapeutic options for the treatment of adenovirus infections; however, the results have been variable. Cidofovir has been shown to exhibit antiviral activity against all human adenovirus species; however, it is associated with low bioavailability, poor correlation of pharmacologic effects with the prescribed dose, and dose-limiting nephrotoxicity. Ribavirin has variable activity against different human adenovirus types, displaying maximum activity against subtype C; however, the evidence for therapeutic efficacy of ribavirin in vivo remains controversial in light of the low plasma concentrations achieved with this compound. The use of ganciclovir is also suggested to treat human adenovirus infections, but its activity against this virus is relatively poor. [0004] 5 '-adenosine diphosphate ribose (ADPR) is a naturally occurring small molecule, which is also available commercially. ADPR has been demonstrated to possess anti -cytotoxic properties, through its identification as a significant contributor to the anti -cytotoxic activity of Lactobacillus bulgaricus extracts; in vitro, ADPR levels as low as 5 mg/L exhibited a

measurable inhibition of tumor necrosis factor alpha (T F-α) mediated cytotoxicity (see Johns et al., 2007, "Cytoprotective Agent in Lactobacillus bulgaricus Extracts," Current Microbiology, 54(2): 131-135). The use of ADPR has also been implicated for preventing, retarding or treating the harmful effects of solar radiation on the skin (see WO 2005/123030 Al). ADPR has also been shown to effectively alleviate mucositis in susceptible individuals, especially when administered prior to, during, or after treatments commonly associated with the development of mucositis such as certain chemotherapies, radiation therapies, or combinations thereof (see WO 03/099297 Al).

[0005] It has been found that ADPR and its compositions provided herein can be used effectively for treating, managing, or preventing adenovirus-related diseases or conditions, eye disorders, cancer, or diseases or conditions caused by infection, inflammation, or physical, chemical, thermal, or radiation injuries.

Excipients can take a wide variety of forms depending on the form of preparation desired for administration. For example, excipients suitable for use in oral liquid or aerosol dosage forms include, but are not limited to, water, glycols, oils, alcohols, flavoring agents, preservatives, and coloring agents. Examples of excipients suitable for use in solid oral dosage forms (e.g., powders, tablets, capsules, and caplets) include, but are not limited to, starches, sugars, micro-crystalline cellulose, diluents, granulating agents, lubricants, binders, and disintegrating agents.

[00123] In one embodiment, oral dosage forms are tablets or capsules, in which case solid excipients are employed. In another embodiment, tablets can be coated by standard aqueous or non-aqueous techniques. Such dosage forms can be prepared by any of the methods of pharmacy. In general, pharmaceutical compositions and dosage forms are prepared by uniformly and intimately admixing the active ingredients with liquid carriers, finely divided solid carriers, or both, and then shaping the product into the desired presentation if necessary.

[00124] For example, a tablet can be prepared by compression or molding. Compressed tablets can be prepared by compressing in a suitable machine the active ingredients in a free- flowing form such as powder or granules, optionally mixed with an excipient.

[00130] Disintegrants may be used in the compositions to provide tablets that disintegrate when exposed to an aqueous environment. Tablets that contain too much disintegrant may disintegrate in storage, while those that contain too little may not disintegrate at a desired rate or under the desired conditions. Thus, a sufficient amount of disintegrant that is neither too much nor too little to detrimentally alter the release of the active ingredients may be used to form solid oral dosage forms. The amount of disintegrant used varies based upon the type of formulation, and is readily discernible to those of ordinary skill in the art. In one embodiment, pharmaceutical compositions comprise from about 0.5 to about 15 weight percent of disintegrant, or from about 1 to about 5 weight percent of disintegrant.

6 EXAMPLES

6.1 Example 1. Plaque inhibition testing of two (2) compounds against adenovirus serotype 3

[00136] Background

[00137] Adenosine 5'-diphosphoribose Sodium Salt ("Compound A" or ADPR, Sigma A0752-500 mg, Lot SLBJ4805V, in one 500 mg vial), and Nicotinamide ("Compound N," Sigma N0636-100G, Lot SLB0315 V, in one 100 gm vial) ("Compound N") were obtained from Sigma. Compound A was solubilized to 120 mg/ml in water for irrigation then further to target concentrations 6 mg/ml and 2 mg/ml in DMEM (Dulbecco s Modified Eagle Medium), 2% FBS (Fetal Bovine Serum; virus growth media). A volume of 10 ml of a 240 mg/ml solution of Compound N was made in water for irrigation. Further dilutions of Compound N were made in DMEM, 2% FBS. Adenovirus plaque inhibition assays were set up on the same day. The remainder of the solubilized Compound A was placed at 4 °C in the dark.

[00138] Dilutions

[00139] Solubilized Compound A was diluted 1 :20 or 1 :60 in virus growth media to make Sample dilutions of 6 mg/ml and 2 mg/ml respectively. Dilutions of Compound N were made into solutions already containing Compound A. The design of the experiment with Groups 1 to 5 is outlined in text below and presented in Table 1. Groups 2, 3 and 4 consist of mixtures of various concentration samples "Samples" of Compound A and Compound N. Group 4 also contains various amounts of cidofovir, an adenoviral antiviral.

[00140] Group 1: Compound N at 0, 60, 600, and 6000 mcg/mL

[00141] Group 2: Compound A at 2000 mcg/mL with Compound N at 0, 60, 600, and 6000 mcg/mL

[00142] Group 3: Compound A (as in the first study) at 6000 mcg/mL with Compound N at 0, 60, 600, and 6000 mcg/mL

[00143] Group 4: Compound A (as in the first study) at 2000 mcg/mL, Cidofovir at 20 micromolar, with Compound N at 0, 60, 600, and 6000 mcg/mL

[00144] Group 5: Cidofovir at 0, 20, and 100 micromolar [00145] Approach

[00146] A549 cells were plated 7 x 10 ⁴ cells per well in 6-well plates. After 18 hours growth media was removed and 1 ml of each Sample mixtures was added. After incubating one hour at 37 °C, approximately 50-75 plaque forming units influenza virus Ad3 were added per well.

[00147] Virus was permitted to adsorb to the cells for two hours and then the media was aspirated from the monolayers and replaced with Ad3 growth media containing Sample dilutions per Table 1, and agarose.

[00148] Toxicity

[00149] Toxicity was evaluated against the below criteria and used to assess the effects of the dilutions of Sample on cell monolayers at the termination of the assay on the end day. Values are recorded in Table 1 as a T value.

0 - No Cytotoxicity

1 - Slight Thinning of Cells compared to Cell Control wells

2 - Moderate thinning of cells compared to Cell Control wells, moderately less intense staining of cells compared to Cell control wells, viral plaques are visible

3 - Extreme thinning of cells compared to Cell Control wells to no cells present, extremely less intense staining of cells compared to Cell Control wells to no

staining due to lack of cells, viral plaques are not visible.

[00150] Results

[00151] Plaque size was reduced with the treatment of Compound A at 2000 and 6000 μg/ml as compared to control, see plaque counts in Table 1 and Figure 1. Additions of increasing concentrations of nicotinamide had an additional effect of decreasing the number of discernable plaques. A concentration of 6000 μg/ml nicotinamide was toxic to A549 cell monolayers in all Groups. At 600 μg/ml concentration nicotinamide alone, the adenovirus plaques appeared much larger, possibly because of its effect on the cell monolayer. When 600 μg/ml nicotinamide was mixed with Compound A in Group 2 and Group 3, there was a decrease in the number of discernable plaques. The addition of 20 μΜ cidofovir was additionally inhibitory in Group 4, and had a synergistic effect compared to Group 3. These results were confirmed by routine image analysis to determine percent plaque area (see Figure 2). Image analysis was performed with Adobe Photoshop. To perform this analysis, contrast was adjusted equally across plates in order to better identify the plaque formations. A standard circular area of 78,456 pixels per plate was selected at the center of each plate to avoid edge artifacts related to the cell culture. The 'Color Range' function was then used to identify the number of white pixels within the circular area and then divided by the total pixel area to compute the percent plaque area. Results were analyzed in Microsoft Excel 2016. Values for duplicate plates were averaged. The synergistic inhibitory effect for cidofovir (20 μΜ) with ADPR (2000 μg/ml) was confirmed in the image analysis (Figure 2) such that the combination had a nearly three-fold benefit (observed 0.25% vs. expected 0.69%) over the expected effect if the compounds were just additive.

[00152] Table 1. Plaque Counts, Toxicity Scores and Plate codes

[00153] Control Drug

[00154] Cidofovir is known to decrease adenovirus plaque size and was used in

concentrations per Table 1. Cidofovir decreased plaques size and number as concentrations were increased.

[00160] Solubilized Sample A and Sample L were diluted 1 : 50, 1 : 150 and 1 :450 in Virus Growth Media to make Sample dilutions. Mixtures of Sample A and L were made by diluting stocks into Virus Growth Media.

[00161] Approach

[00162] A549 cells were plated 7 x 10 ⁴ cells per well in 6-well plates. After 18 hours, growth media was removed and 1 ml of each Sample mixtures was added. After incubating one hour at 37 °C, approximately 50-75 plaque forming units Ad3 were added per well. Virus was permitted to adsorb to the cells for two hours and then the media was aspirated from the monolayers and replaced with Virus Growth Media containing Sample dilutions per Table 3, and agarose. [00163] Toxicity

[00164] Toxicity was evaluated against the below criteria and used to assess effects of the dilutions of Sample on cell monolayers at the termination of the assay on the end day. Values are recorded in Table 3 as a T value.

0 - No Cytotoxicity

1 - Slight Thinning of Cells compared to Cell Control wells

2 - Moderate thinning of cells compared to Cell Control wells, moderately less intense staining of cells compared to Cell control wells, viral plaques are visible

3 - Extreme thinning of cells compared to Cell Control wells to no cells present, extremely less intense staining of cells compared to Cell Control wells to no

staining due to lack of cells, viral plaques are not visible.

[00165] Results

[00166] Plaque size was reduced with treatment of Sample A at 0.44, 1.33 and 4.0 mM as compared to control. Adenovirus plaques appeared much larger than the control at 1.33 mM concentration of Sample L alone. A synergistic effect of combining Sample A and Sample L at 4 mM each was observed - plaques were determined to be smaller on average than the control- treated cultures. Neither Sample was cytotoxic at concentrations tested. Plaque counts are depicted in Table 3 below, and plate images are depicted in Figure 3. Figure 4 depicts percent plaque inhibition of adenovirus serotype 3 by Sample A (i.e., ADPR), Sample L (i.e., LiCl), and combination of Sample A and Sample L at 4 mM concentration. This analysis was done by routine image analysis to determine percent plaque area (see Figure 4). Image analysis was performed with Adobe Photoshop. To perform this analysis, contrast was adjusted equally across plates in order to better identify the plaque formations. A standard circular area of 45,621 pixels per plate was selected at the center of each plate to avoid edge artifacts related to the cell culture. The 'Color Range' function was then used to identify the number of white pixels within the circular area and then divided by the total pixel area to compute the percent plaque area. Results were analyzed in Microsoft Excel 2016. Values for duplicate plates were averaged. As shown in Figure 4, a synergistic effect was observed by combining Sample A and Sample L at 4 mM concentration of each sample. The combination had a 31% improvement (observed 6.31% vs. expected 9.11%) over the expected effect if the compounds were just additive. [00167] Table 3. Plaque Counts, Toxicity Scores and Plate Codes

[00168] This assay used the same raw materials and control drug as described in Example 1.

6.3 Example 3. Test pilot study to develop a viral conjunctivitis model in New

Zealand white rabbits

[00169] Purpose/Objective (s): The purpose of this study was to develop a viral conjunctivitis model in New Zealand White rabbits.

[00170] Protocol

[00171] Animal Preparation: Three animals were anesthetized with an intramuscular injection of ketamine (up to 50 mg/kg) and xylazine (up to 10 mg/kg) for the viral inoculation procedures. Following anesthesia, the eyes were cleaned with betadine and then rinsed with basic salt solution (BSS). A wire lid speculum was inserted to retract the lids. One to two drops of proparacaine (0.5%) was applied to both eyes. Corneal scarification was performed on Day 0. The epithelium layer of each cornea was scarified with a 3x3 cross-hatch patter scratch with a 25 gauge sterile needle. Following corneal scarification, both corneas of each rabbit were inoculated topically with 2 xlO ⁶ PFU of adenovirus, serotype 5 (Ad5). To accomplish this, 0.02 mL of the 1.1 x 10 ⁸ PFU Ad5/mL solution was delivered topically using a sterile pipette.

Following Ad5 inoculation, animals were recovered from the anesthetic event.

[00172] Test and Control Article

[00173] The test article, 2.0% adenosine-diphosphoribose (sodium salt) formulation containing 0.057%> tetraborate, 1.20% boric acid, and 0.02% PEG-300, was prepared and its pH was adjusted to 7.08. The control article, a buffer solution containing 0.2% NaCl, 0.057% tetraborate, 1.20% boric acid, and 0.02% PEG-300, was prepared and its pH was 6.97.

[00174] Test and Control Article Administration

[00175] Treatments were given according to the study design table below (see Table 4). The test or control article was administered via topical administration three times daily (25 μΙ_, per drop with two drops per dose) (TID) for the study duration.

[00176] Table 4. Study Design

TID: three times a day

[00177] Summary of the Results

[00178] Ocular examinations using the McDonald-Shadduck scoring system showed some discharge above normal (scores of " 1 ") from days 1 through 4, but was more abundant for all groups on the day 7 exams (scores of "2"). By day 10 the discharge was less except for the group 2 animal P7279. The conjunctiva congestion was not as robust, however, the day 1 scores were the highest (50% of the scores were "2") for all three animals. Although the conjunctival congestion scores for days 7 and 10 were mostly "2," the congestion was limited to the third eyelid. It should be noted that the third eyelid is even more sensitive to irritants then the conjunctiva itself.

[00179] Figures 5-7 summarize the changes observed on the corneal surface at the site of the viral inoculation. Corneal scratches provide the base for the virus to attach to the corneal epithelium and were the sites where the corneal opacities and cloudiness appeared. Over the course of the study, animal no. P7280 treated with the test article appeared to have the largest improvement with decreased corneal opacities both on the corneal scratches and the corneal surface areas as well.

[00180] Conclusion

[00181] The Test Article Dose A - 2% appeared to reduce the corneal opacities when compared to the vehicle and the untreated control.

6.4 Example 4. Synthesis of dilithium ADPR (L1 ₂ ADPR)

[00182] Dilithium ADPR (Li ₂ ADPR) was synthesized from the free acid of nicotinamide adenine dinucleotide (NAD+) under lithium hydroxide hydrolysis conditions. The synthetic scheme is outlined below:

[00183] Scheme 1. Synthesis of dilithium ADPR (Li ₂ ADPR)

[00184] The materials utilized are shown in Table 5. [00185] Table 5. Materials

[00186] The instrumentation parameters are shown in Table 6.

[00187] Table 6. Instrumentation Parameters

[00188] The starting material β-nicotinamide adenine dinucleotide (NAD+) was purchased from Codexis as a free acid and was used for the hydrolysis by lithium hydroxide to remove the nicotinamide moiety, resulting in adenosine 5'-diphosphoribose (ADPR) lithium salt. Excess LiOH was added to maintain the reaction solution pH between 10-10.5. The hydrolysis was monitored by HPLC. Hydrolysis was judged to be complete after 8 days. The hydrolyzed product was isolated by trituration in MeOH, water and EtOH to remove excess LiOH and nicotinamide.

[00189] Experiment and results

[00190] NAD+ (10.00 g, 15.07 mmol) was dissolved in water (250 L). Solid LiOH was added to adjust the solution from pH 2.78 to 11.21. The amount of LiOH H ₂ 0 added was 0.809 g. Slight color change to light yellow was noticed and slightly exothermic process was detected. Gradual pH decrease was observed while the hydrolysis was proceeding. The solution was stirred at room temperature (RT) for 8 days, during which LiOH H ₂ 0 was added periodically to maintain the reaction solution pH 10-10.5. The total amount of LiOH H ₂ 0 utilized to drive the reaction to completion was 1.624 g (2.57 eq.). The progress of the reaction was monitored by HPLC analysis. At the end of the reaction, the solution had a red-wine color with small amount of white precipitate on top of the solution. The solid was removed by filtration. Activated charcoal (-35 g) was added. The mixture was stirred at RT for 20 hours and filtered to give a light yellow filtrate. The filtrate was concentrated by rotary evaporation. The residue was suspended in MeOH (100 mL), stirred at RT for 1 hr and filtered. An aliquot of the solid from the filtration was dissolved in water and its pH was 10. The filtrate was evaporated and the residual solid was dried under high vacuum. An aliquot of the solid was dissolved in water and its pH was ~7. This solid was suspended in EtOH (50 mL) and the suspension was stirred at RT for 2 days. The solid was collected by filtration, rinsed with EtOH (10 mL) and further dried under high vacuum to give 3.246 g of a light yellow solid.

[00191] This solid sample was submitted for elemental analysis and the results are shown in Table 7, confirming the product as a dilithium salt with a molecular formula C15H21L12N5O14P2- 1.1H ₂ 0. ADPR was further confirmed by HPLC (see Figure 8) and mass spectrometry (see Figure 9) analysis.

[00192] Table 7. Elemental analysis results

6.5 Example 5. Efficacy of dilithium ADPR against adenovirus— in vitro study [00193] Background

[00194] Dilithium ADPR, 150 mg powder, was stored in a glass vial ("Sample A") at 4 °C in the dark until use. On the day of assay, Sample A was solubilized to 200 mg/ml in 750 μΕ water for irrigation, then further diluted to target concentrations. The compound went into solution easily. Solubilized Sample A was tested for plaque inhibitory properties against Adenovirus 3 and Adenovirus 5 (Ad3 & Ad5).

[00195] Dilutions

[00196] Solubilized Sample A was diluted to 4 mg/mL, 2 mg/mL, 1 mg/mL and 0.5 mg/mL in Virus Growth Media (DMEM, 2% Fetal Bovine Serum (FBS) and antibiotic, antimycotic).

[00197] Approach [00198] A549 cells were plated 7 x 10 ⁴ cells per well in 6-well plates. After 18 hours, growth media was removed and 1 mL of each sample mixtures was added per well. After incubating for one hour at 37 °C, approximately 50-75 plaque forming units Ad3 and separately Ad5 were added per well. Virus adsorbed to the cells for two hours and then media was aspirated from the monolayers and replaced with Virus Growth Media containing Sample A dilutions of 0, 0.5, 1.0, 2.0, and 4.0 mg/mL, and agarose.

[00199] Results

[00200] Ad3 and Ad5 plaque size and number were reduced by Sample A at 4 mg /mL and 2 mg/mL. In addition, the monolayers showed moderate thinning at 4 and 2 mg/mL compared to control wells with less intense staining than control wells. The thin monolayer made it hard to delineate plaques. Very few plaques were visible as compared to control. At dilutions of 1 mg/mL and 0.5 mg/mL, Ad3 and Ad5 plaque size and number were reduced in number and size, and the monolayer showed slight thinning as compared to cell control wells. Mean plaque counts at Sample A concentrations were as follows:

Ad3 : 4 mg/mL - 29; 2 mg/mL - 10; 1 mg/mL - 44; 0.5 mg/mL - 54; 0 mg/mL - 55 Ad5: 4 mg/mL - 7; 2 mg/mL - 7; 1 mg/mL - 25; 0.5 mg/mL - 53; 0 mg/mL - 65

[00201] Conclusion

[00202] Dilithium ADPR demonstrated that it effectively reduced cytopathic effect as indicated by plaque size and number caused by adenovirus (Ad3 and Ad5) grown in cell culture in A549 cells. In addition, the dose responsive thinning of the monolayer is consistent with the reduced replication observed in other cancer cell lines described in Example 7.

[00224] (b) Vehicle: 55.8 mg sodium chloride, 18 mg of sodium tetraborate, 180 mg of boric acid, and 63 mg of PEG-300 were weighed out into a vial. 14 mL DI water was added, and vial contents were swirled, vortexed, and/or sonicated if needed until a clear solution is formed. The pH of the solution was tested using pH tester strips and adjusted to 7.0-7.2, if necessary, using sodium hydroxide (NaOH) or additional boric acid. The volume was then brought up to 18 mL with additional DI water to make a 0.31% sodium chloride, 0.1% sodium tetraborate, 1% boric acid, 0.35% PEG-300 solution. The vial contents were sterile filtered through a 0.2 or 0.22 μιη filter.

The solution was transferred to the vial containing dilithium ADPR. The volume was brought up to 9.5 mL with DI water, and vial contents were swirled, vortexed, and/or sonicated if needed until a clear solution is formed. The pH of the solution was tested using pH tester strips and adjusted to 7.0- 7.2, if necessary, using sodium hydroxide (NaOH) or additional boric acid. The volume was then brought up to 12 mL with additional DI water to make a 2.0% dilithium ADPR solution. The vial contents were sterile filtered through a 0.2 or 0.22 μπι filter.

[00226] (d) Dilithium ADPR - Mid Dose: 1 part vehicle and 1 part high dose formulation were mixed to make a 1.0% dilithium ADPR solution.

Prior to dosing, dosing solutions were allowed to come to room temperature. After dosing, aliquots were stored or discarded in the room holding the study animals, and were not transferred back into the formulation room or any other room in the vivarium.

6.6.1.4 Details of test/control article administration

[00229] 1. Pre-Treatment Examinations

[00230] Prior to placement on study, each animal underwent an ophthalmic examination (slitlamp biomicroscopy and indirect ophthalmoscopy) performed by the Study Director. Ocular findings were scored according to a modified McDonald-Shadduck Scoring System (see Section 6.6.1.5). The acceptance criteria for placement on study was scores of "0" for all variables.

[00231] 2. Anesthesia

[00232] Animals were anesthetized with an intramuscular injection of ketamine (up to approximately 50 mg/kg) and xylazine (up to approximately 10 mg/kg) for the viral inoculation procedures.

[00233] 3. Corneal scarification and Viral Inoculation Procedure

[00234] Viral inoculation was performed in both eyes of all study animals on Days -1 and 0. Animals were anesthetized as described above. The eyes were cleaned with betadine (no betadine was used on Day 0) and then rinsed with basic salt solution (BSS). A wire lid speculum was inserted to retract the lids. One to two drops of proparacaine (0.5%) were applied to both eyes. Additional topical anesthetics may be used during the procedure as necessary. Corneal scarification was performed in both eyes by scarifying the epithelium layer of each cornea with a 3x3 cross-hatch patter scratch with a 25 gauge sterile needle. Following corneal scarification, both corneas of each rabbit were inoculated by delivering 0.015 mL (15 xL) of the 1.61 x 10 ⁸ PFU Ad5/mL solution topically to each eye for each inoculation using a sterile pipette, resulting in a dose of 2.42 xlO ⁶ PFU of Ad5 per eye. Following each Ad5 inoculation, animals were recovered from the anesthetic event.

[00235] 4. Group Assignment

[00236] On Day 1 prior to dosing, infection severity were evaluated in all animals, and the animals were assigned to one of 4 experimental groups (see below) based on infection severity. Animals were assigned a numeric rank from 1 to 8 according to infection severity in a decreasing order (the animal with the most severe infection was assigned rank = 1). They were then assigned to the experimental groups according to the following scheme:

Group Assignment Table

[00237] 5. Test/Control Article Administration

[00239] 6. In-Life Observations and Measurements

[00240] (a) General Health Observations: Animals were observed within their cages once daily throughout the study period. Each animal was observed for changes in general appearance and behavior. Any abnormal observations were reported to the Study Director.

General health observations were performed and recorded daily starting on Day -1 and continuing throughout the duration of the study (total of 9 days).

[00241] (b) Body Weights: Animals were weighed prior to inoculation and prior to euthanasia.

[00242] (c) Clinical Ophthalmic Examinations: Clinical ophthalmic examinations

(slit-lamp biomicroscopy only) were performed on Days 1, 2, 3, and 7. On Day 1, examinations were performed prior to the start of dosing. On all other days, examinations were performed -30 minutes following the last dose of the day (i.e., the third dose). On Day 7, examinations were performed immediately prior to euthanasia of the animals. Slit-lamp examinations were performed by the Study Director. Ocular findings were scored according to a modified

McDonald-Shadduck Scoring System (see Section 6.6.1.5 below).

[00243] (d) Slit-lamp Photographs: Slit-lamp photographs were taken on Days 1, 3, and 7. On Day 1, photographs were taken prior to the start of dosing. On all other days, photographs were taken -30 minutes following the last dose of the day (i.e., the third dose). On Day 7, photographs were taken immediately prior to euthanasia of the animals.

6.6.1.6 Results

[00408] The combined injury and infection with corneal scarification and Ad5 inoculation was very successful at inducing consistent corneal and conjunctival inflammation. The composite score significantly improved (p < 0.01) in all of the treated groups on Days 3 and 7 compared to the baseline score on Day 1. These results are graphically shown in Figure 10.

[00409] Furthermore, the subscores of Conjunctival Congestion and Surface Area of Corneal Involvement were primarily effected. These also showed improvement that was statistically significant in all treated groups (p < 0.01 for Conjunctival Congestion and p < 0.05 for Surface Area of Corneal Involvement) on Days 3 and 7 compared the baseline score on Day 1. The results are graphically shown in Figures 1 1 A and 1 IB.

6.6.1.7 Conclusion

[00410] The results demonstrated a rapid resolution of the combined adenoviral and physical injury effects in the eyes treated with dilithium ADPR in solution. All doses used (0.5%, 1.0%, and 2.0%) were effective, p < 0.01, with > 80% reduction in the composite score by Day 7. The vehicle control group did not show a significant improvement by Day 7.

6. 7 Example 7. Efficacy in cancer— Cell Viability Assay (in vitro study)

[00411] Cell viability was measured by the CellTiter-Glo® cell viability assay Promega (Madison, Wis.). The CellTiter-Glo® Luminescent Cell Viability Assay is a homogeneous method to determine the number of viable cells in culture based on quantitation of the ATP present, which signals the presence of metabolically active cells. Following treatment, CellTiter- Glo® was added to treatment wells and incubated at 37° C. Luminescence values were measured at using a Molecular Devices Spectramax microplate reader.

[00412] Cells were grown to 70% confluency, trypsinized, counted, and seeded in 384 well flat-bottom plates at a final concentration of Ι .Ο ^χ 10 ³ -1.5 ^χ 10 ³ cells/well (Day 0). Cells were allowed to incubate in growth media for 24 hours to allow for maximum adhesion. Treatment with the test agents began on Day 1 and continued for 72 hours. At the 72-hour time point, treatment-containing media was removed. Viable cell numbers were quantified by the CellTiter- Glo® cell viability assay as described above. Experiments were run with triplicate concentrations to determine growth inhibitory activity. Results from these studies were used to calculate an IC ₅₀ value (concentration of drug that inhibits cell growth by 50 percent of control) for each compound.

[00413] Data Collection - For single agent and combination studies, data from each experiment was collected and expressed as % Cell Growth using the following calculation:

[00414] (i) % Cell Growth = ( fyehicie) ^x 100

[00415] (ii) Where f _tes t is the luminescence of the tested sample, and f _ve hicie is the

luminescence of the vehicle in which the drug is dissolved. Dose response graphs and IC50 values were generated using Prism 6 software (GraphPad).

[00416] The following compounds (concentrations) were evaluated:

[00417] (i) Lithium Chloride (30, 300, 1000, 3000 μΜ, and 6000 μΜ; 6000 μΜ only tested for MV411 cells)

[00418] (ϋ) Dilithium ADPR (30, 300, 1000, and 3000 μΜ)

[00419] (iii) SN38 as positive control (0.03, 0.1, 0.3, 1.0, 3.0, 10, and 30 μΜ)

[00420] The following cell lines were evaluated:

[00421] (i) AsPCl - human pancreatic adenocarcinoma

[00422] (ϋ) H1437 - human, lung adenocarcinoma, non-small cell lung cancer

[00423] (iii) U87-MG - human, brain glioblastoma

[00424] (iv) MV411 - human, myelomonocytic leukemia

[00425] Results are expressed as IC50S (μΜ, average of two values) in the table below:

[00426] Conclusion: The inhibition of cellular replication by dilithium ADPR is remarkable since the lithium ion as lithium chloride at similar molar concentrations dilithium ADPR was not effective, and ADPR alone is not known to reduce cellular replication. This indicates that the two components, lithium and ADPR, combine in a synergistic fashion to stabilize these cancer cell lines and limit their replication. 6.8 Example 8. ADPR alone (as sodium salt) does not reduce replication and/or induce cytotoxicity of A549 cells

[00427] ADPR, sodium Salt, (Sigma A0752), was tested in A549 (human alveolar adenocarcinoma) cell culture to determine its effect on replication. ADPR was evaluated at five concentrations by incubation for 48 hours with A549 cells (previously grown to a monolayer) at 37 °C. After incubation, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) dye was added to each well and live cells were measured by blue dye incorporation.

[00428] Concentrations of ADPR (sodium salt) tested were 24, 12, 6, 3, 1.5, and 0 mg/mL. Average MTT incorporation as measured by OD560 were 0.55±0.02, 0.69±0.01, 0.72±0.04, 0.61±0.09, 0.62±0.08, and 0.67±0.02 respectively.

[00429] ADPR (sodium salt) did not reduce MTT incorporation up to 12 mg/mL, with only a mild reduction at 24 mg/mL. Therefore, ADPR alone (as the sodium salt) does not reduce cellular replication in A549 cells up to 12 mg/mL (equal to 21 mM), with only a small reduction at 24 mg/mL (eaual to 42 mM). Therefore, this further supports that the combination of lithium and ADPR as dilithium ADPR (as shown in Examples 6 and 7) demonstrates remarkable synergy between lithium and ADPR.
