2. Description of Related Art
When a psychiatrist is presented with a patient exhibiting one or more behaviors such as poor social skills, defiance, lack of patience, difficulty paying attention, ritualistic behavior and/or mood swings, where such behavior(s) interferes with normal functioning, the psychiatrist must first make a diagnosis before formulating a treatment plan.
Today, the psychiatrist's nomenclature, i.e., the criteria for psychiatric evaluation and classification is provided in the Diagnostic and Statistical Manual of Mental Disorders (“DSM”), a periodically revised psychiatric “Bible” published by the American Psychiatric Association. The current version of the DSM is DSM 5.0, which was published on May 18, 2013.
The psychiatrist's professional judgment in rendering a diagnosis is largely informed by the criteria for various disorders set forth in the DSM. Thus, a psychiatrist presented with a patient exhibiting any such symptoms as those described above would consult the DSM in rendering a diagnosis. The diagnosis would, in turn, inform a treatment program. Whether a given patient is determined, for example, to have ADHD as opposed to Hypomania in Bipolar Disorder, depends on whether the patient's symptoms comport with criteria set forth for these conditions in the DSM. Proper diagnosis is critical since a wrong diagnosis will likely lead to an ineffective or even potentially harmful treatment program.
The DSM 5.0 definition of Autism Spectrum Disorder (“ASD”) is as follows:
Part A of the DSM 5.0 definition of ASD and Part B of the DSM 5.0 definition of ASD are hereinafter collectively referred to as “core symptoms” of ASD or “core ASD symptoms,” since they are, by definition, present in all ASD patients. Throughout this specification, the constituent symptoms of the core symptoms of ASD may be individually referred to respectively as “part A of the DSM 5.0 definition of ASD” and “part B of the DSM 5.0 definition of ASD.”
Other symptoms that may be manifest in ASD patients and which are associated with their ASD are referred to herein as “associated symptoms” of ASD or “associated ASD symptoms”. Such associated symptoms of ASD may include at least one of the following: impulsivity, concentration deficit or attention deficit and emotional lability/irritability.
The term “impulsivity,” as used herein, is characterized by the following: often blurts out answers before questions have been completed and/or often has difficulty waiting for his/her turn and/or often interrupts or intrudes on others (e.g., butts into conversations or games).
The terms “concentration deficit” and “attention deficit” are synonymous with each other and are therefore interchangeable. As used herein, the terms “concentration deficit” and “attention deficit” are characterized by the following: deficits in concentration as evidenced by often having difficulty sustaining attention in tasks or play activities, often does not seem to listen when spoken to directly, is often easily distracted by extraneous stimuli.
The terms “emotional lability” and “irritability,” are synonymous with each other and are therefore interchangeable. As used herein, “emotional lability” and “irritability” are compounded into the single term (which is synonymous with each individual term): “emotional lability/irritability.” Emotional lability/irritability is characterized by the following: severe, reactive mood swings in response to real or perceived situations where demanded needs are not being met in the environment. Emotional lability/irritability may optionally be measured using the Aberrant Behavior Checklist irritability subscale.
The Applicant has discovered a pervasive subpopulation within ASD that responds particularly well to a combination therapy that the Applicant has invented. In addition to the core symptoms of DSM 5.0 ASD, defined above, the Applicant has found patients in this subpopulation have one or more (usually all) associated symptoms of ASD, as defined above (i.e., impulsivity, concentration deficit or attention deficit and/or emotional lability/irritability). The combination therapy to treat ASD that Applicant invented, namely administering a therapeutically effective amount of an alpha-2 adrenergic agonist in an extended release dosage form in combination with a therapeutically effective amount of inositol, is described in detail in the following of Applicant's patent applications, all of which are incorporated by reference herein in their entireties: WO 2014/168820 and U.S. Pat. Pub. Nos. 2014/0309271, 2014/0309270 and 2014/0309269.
Based on Applicant's experience and insights, the aforementioned combination therapy is a superior treatment for ASD compared to use of either agent alone. For example, neither agent alone is effective in treating all core symptoms of ASD and associated symptoms of ASD, whereas the combination is effective in treating all such symptoms. Moreover, Applicant has found that the combination exhibits a synergistic effect in treating Part A of the DSM 5.0 definition of ASD and emotional lability/irritability.
Notwithstanding the superior efficacy of the combination over administration of either agent alone in ASD, monotherapy with only one of these agents is still far more effective than either doing nothing or administering other known drugs. Applicant has seen cases in which ASD patients were misdiagnosed based on patients' presenting associated symptoms of ASD, which treating physicians misinterpreted as being indicative of underlying conditions unrelated to ASD. Such misdiagnoses led to prescribing drugs that either did not help or exacerbated these patients' symptoms, and/or caused serious side effects. Such drugs included psychostimulants, Strattera, Wellbutrin, Provigil, Nuvigil, Tenex, propranonol, selective serotonin re-uptake inhibitors, serotonin and norepinephrine reuptake inhibitors, mood stabilizers and atypical antipsychotics. See, e.g., Examples 1 and 2 of Applicant's U.S. Pat. Pub. 2014/0309270.
Whereas the aforementioned drugs were found to be ineffective or harmful to ASD patients, Applicant has found that an extended release alpha-2 adrenergic agonist, such as extended release clonidine (e.g., marketed as KAPVAY®) or extended release guanfacine (e.g., marketed as INTUNIV®) as monotherapy for ASD is effective in treating some ASD symptoms. Likewise, Applicant has found that high doses of inositol are effective as a monotherapy in treating some ASD symptoms. While Applicant's combination therapy is superior and preferred for treating ASD over monotherapy using either agent alone, such monotherapy is still an improvement over anything else known to Applicant (aside of course from Applicant's combination therapy). Given the urgency of the health need for effective ASD treatment, and the fact that regulatory approval of any new drug (in this case, the combination therapy) generally takes years, there is a need for a readily available treatment for ASD patients.
Inositol is a natural supplement that is already widely available, e.g., in vitamin stores, without a prescription. Applicant has discovered that high doses of inositol are safe and effective in treating Part B of the DSM 5.0 definition of ASD and the associated symptom of ASD of emotional lability/irritability. Alleviation of these symptoms alone would provide some relief to ASD patients and their caretakers. While there are exceptions, Applicant has found that therapeutic doses of inositol for ASD patients tend to be about 9,000 mg to about 32,400 mg per day. Inositol is typically available as a supplement, e.g., in powder form. Given the large amounts of inositol generally necessary to provide therapeutic doses to ASD patients, such commercially available inositol is not typically administered orally without being mixed with some other substance. For example, inositol is typically mixed into a drink or semi solid food, e.g., applesauce.
Since ASD patients are very particular, they generally do not respond well to medicines with strong tastes or smells. Inositol powder is somewhat sweet and does not have an offensive taste or odor. Thus, inositol is not a difficult substance for an ASD patient to ingest. In fact, it is possible that the inositol can be administered, even in large amounts, when mixed with other substances, without the ASD patient knowing he/she is taking medicine.
In order to make inositol more readily available to the ASD population and patients' caretakers, it is desirable to provide the inositol in flavorsome foods, administered in units that contain precise predetermined amounts of inositol.
Accordingly, in one aspect, the present invention is directed to a method for treating a patient having ASD. As used herein, the term ASD is defined as the diagnostic criteria for DSM 5.0 as published by the American Psychiatric Association. The method includes administering to the patient a therapeutically effective amount of inositol, preferably in a plurality of comestible units, e.g., baked goods such as cookies. A therapeutically effective amount of inositol is an amount that will reduce one or more core symptoms of ASD or associated ASD symptoms. Thus, in one aspect, the method includes administering to the ASD patient a plurality of comestible units, e.g., cookies, cumulatively comprising a therapeutically effective amount of inositol. Optionally, the plurality of comestible units comprising inositol may be administered to a patient having ASD in combination with a therapeutically effective amount of an alpha-2 adrenergic agonist in an extended release dosage form.
In another aspect, the present invention is directed to a method for reducing, to a clinically meaningful degree, one or more symptoms associated with ASD in a patient having ASD. The method includes administering to the patient a maximum effective dose of inositol. The maximum effective dose of inositol is determined by providing an amount of inositol to the patient that induces diarrhea and then titrating down to a lower dose that does not induce diarrhea but is immediately below a dose which does induce diarrhea. As used herein in the foregoing context, the term “immediately below” means less than an amount which induces diarrhea, although not substantially less that amount. For example, “immediately below” may mean within 10% of the amount of inositol that induces diarrhea in the patient. The maximum effective dose according to this method is the lower dose.
In another aspect, the present invention is directed to a method for reducing, to a clinically meaningful degree, one or more symptoms associated with ASD in a patient having ASD, e.g., part B of the DSM 5.0 definition of ASD and/or emotional lability/irritability. The method comprises administering to the patient a therapeutically effective amount of inositol, wherein the therapeutically effective amount of inositol is from about 9,000 mg to about 32,400 mg per day. This may be achieved, e.g., through administering a plurality of comestible units, each comprising a predetermined amount of inositol.
Whether administered as a monotherapy for ASD or in combination with an extended released alpha-2 adrenergic agonist, inositol according to the present invention is preferably administered via comestible units, as described below.
As used herein, the phrase “greater efficacy in reducing” with respect to one or more symptoms, means that based on a psychiatrist's qualitative evaluation using ordinary skill and/or evaluation using a recognized quantitative scale in the field of ASD, optionally the Social Responsiveness Scale (“SRS,” explained more fully below), the improvement in the one or more symptoms is greater, and preferably unexpectedly greater using the inositol-containing comestible, than a placebo (e.g., placebo comestible).
The phrase “to a clinically meaningful degree” as used herein means noticeable reduction in a given symptom based on a psychiatrist's qualitative evaluation using ordinary skill and/or evaluation using a recognized quantitative scale in the field of ASD, optionally the SRS. The method includes reducing, to a clinically meaningful degree, part B of the DSM 5.0 definition of ASD and/or emotional lability/irritability in a patient having ASD.
Inositol or cyclohexane-1,2,3,4,5,6-hexol is a chemical compound with formula C6H12O6 or (—CHOH—)6, a sixfold alcohol (polyol) of cyclohexane. Inositol exists in nine possible stereoisomers. The most prominent form, widely occurring in nature, is cis-1,2,3,5-trans-4,6-cyclohexanehexol, or myo-inositol (former name meso-inositol). Inositol has been shown to have a taste that is half the sweetness of table sugar. For this reason, the Applicant has found the taste of inositol to be well tolerated by ASD patients who are very particular and who thus do not respond favorably to medications with strong tastes or smells.
The isomer myo-inositol—again the most prominent form of naturally occurring inositol—is a meso compound which has an optically inactive plane of symmetry through the molecule. Besides myo-inositol, the other naturally occurring (albeit uncommon) stereoisomers are scyllo-, muco-, D-chiro-, and neo-inositol. Other isomers are L-chiro-, allo-, epi-, and cis-inositol.
The structure of the most common natural form of inositol, myo-inositol, is shown below:
A preferred form of inositol for use according to some embodiments of the present invention is myo-inositol sold in powder form under the name FREEDA®. Unless otherwise stated in this specification, the term “inositol” or “standard inositol” refers to myo-inositol having a potency substantially similar to that of the inositol powder referenced above, e.g., sold under the name FREEDA®, or other brands and dosage forms having substantially similar potencies. Therapeutically effective doses of inositol (e.g., in powder form) for patients with ASD may generally range from about 4,500 mg to about 32,400 mg per day and preferably from about 9,000 mg to about 32,400 mg per day and especially preferably from about 12,000 mg to about 32,400 mg per day, or optionally from about 12,000 mg to about 24,000 mg per day, or optionally from about 12,000 to about 18,000 mg per day. Once daily administration of inositol within the foregoing dosage amounts is within the scope of the invention. However, twice daily or three times daily administration is preferred. For example, if a preferred daily dose of inositol for a given patient is 21,000 mg, it is preferred that the inositol be administered to the patient, e.g., 10,500 mg in the morning and 10,500 mg in the evening (twice daily dosing) or 7,000 in the morning, 7,000 around lunch time and 7,000 in the evening (three times daily dosing). For a minority of patients, especially in an adult ASD population (over age 18), therapeutically effective doses of inositol may be less than 4,500 mg/day to as low as about 500 mg/day.
In treating ASD patients with inositol, the Applicant has discovered, among other things, the following noteworthy phenomena:
While it is currently preferred that the inositol is administered within the nominal dosage ranges described above, it is contemplated that the potency of inositol may be increased such that it may be administered in lesser nominal amounts than described above with reference to standard inositol, but still provide therapeutically equivalent effectiveness within the scope of the present invention. For example, the Applicant contemplates that inositol could be effectively administered in two to three times lower doses than the nominal amounts described above according to the teachings of U.S. Pat. No. 8,557,792, the entirety of which is incorporated herein by reference. That patent discloses a vitamin B 12 formulation and inositol is considered to be part of the vitamin B complex.
If taken in powder form, inositol is typically dissolved in food or drink. It is contemplated that the inositol can also be administered in solid oral dosage forms too, such as in tablets or capsules. Preferably, in accordance with an aspect of the present invention, the inositol powder is mixed into comestible units, such as cookie dough, in predetermined amounts adapted to provide therapeutic doses of inositol to an ASD patient through administration of a plurality of such units to the patient. These comestible units are discussed in greater detail, below.
In one aspect, the present invention is directed to a method for reducing, to a clinically meaningful degree, one or more symptoms associated with ASD in a patient having ASD, e.g., part B of the DSM 5.0 definition of ASD and/or emotional lability/irritability. The method comprises administering to the patient a therapeutically effective amount of inositol, wherein the therapeutically effective amount of inositol is from about 9,000 mg to about 32,400 mg per day. This may be achieved, e.g., through administering a plurality of comestible units comprising a predetermined amount of inositol to an ASD patient. The comestible unit is a solid or substantially solid food, as opposed to a drink. The comestible unit is preferably a baked good, candy or other food that is appealing to ASD patients, especially children, who are particularly sensitive to bad tastes and odors. Preferably, the comestible unit is a cookie or other small measured quantity of food that is not overly filling per unit. In this way, a patient may consume therapeutic doses of inositol by consuming a plurality of such units. Preferably, a comestible unit is packaged together with a plurality of other similarly sized units, wherein every unit contains substantially the same amount of inositol. In this way, an ASD patient or caretaker does not need to premeasure inositol powder for each administration and mix the powder into a delivery liquid (e.g., juice) or semi-solid food (e.g., applesauce). The comestible units thus simplify administration of inositol and make taking the medicine an enjoyable experience for the ASD patient.
Optionally, each comestible unit (e.g., cookie) includes predetermined amounts of from 1,000 to 7,000 mg of inositol, optionally from 1,500 to 6,000 mg of inositol, optionally from 2,000 to 5,500 mg of inositol, optionally from 2,000 to 4,500 mg of inositol, optionally from 2,000 to 3,000 mg of inositol, optionally from 2,500 to 4,500 mg of inositol, optionally from 2,500 to 3,500 mg of inositol, optionally from 3,000 to 4,500 mg of inositol, or optionally precisely or about (i.e., plus or minus 50 mg) any of the following amounts of inositol: 1,500 mg, 1,600 mg, 1,700 mg, 1,800 mg, 1,900 mg, 2,000 mg, 2,100 mg, 2,200 mg, 2,300 mg, 2,400 mg, 2,500 mg, 2,600 mg, 2,700 mg, 2,800 mg, 2,900 mg, 3,000 mg, 3,100 mg, 3,200 mg, 3,300 mg, 3,400 mg, 3,500 mg, 3,600 mg, 3,700 mg, 3,800 mg, 3,900 mg, 4,000 mg, 4,100 mg, 4,200 mg, 4,300 mg, 4,400 mg, 4,500 mg, 4,600 mg, 4,700 mg, 4,800 mg, 4,900 mg, 5,000 mg, 5,100 mg, 5,200 mg, 5,300 mg, 5,400 mg, or 5,500 mg.
Since inositol has a sweet taste, the foregoing exemplary amounts of inositol may be used to reduce or replace sugar in comestible units according to the present invention. For example, in one embodiment, the invention may be a cookie made from the following ingredients: unbleached flour, vegetable oil, a predetermined amount of inositol, (optionally) sugar, cocoa, eggs, water, honey, salt, leavening and vanilla, wherein the predetermined amount of inositol per cookie is optionally precisely or about (i.e., plus or minus 50 mg) any of the following: 1,500 mg, 1,600 mg, 1,700 mg, 1,800 mg, 1,900 mg, 2,000 mg, 2,100 mg, 2,200 mg, 2,300 mg, 2,400 mg, 2,500 mg, 2,600 mg, 2,700 mg, 2,800 mg, 2,900 mg, 3,000 mg, 3,100 mg, 3,200 mg, 3,300 mg, 3,400 mg, 3,500 mg, 3,600 mg, 3,700 mg, 3,800 mg, 3,900 mg, 4,000 mg, 4,100 mg, 4,200 mg, 4,300 mg, 4,400 mg, 4,500 mg, 4,600 mg, 4,700 mg, 4,800 mg, 4,900 mg, 5,000 mg, 5,100 mg, 5,200 mg, 5,300 mg, 5,400 mg, or 5,500 mg.
Preferably the comestible units are packaged with a plurality of other such units, with printed indicia on or in a package containing such units, communicating that the units and/or high doses of inositol may be effective in treating ASD or have been shown to be effective in treating ASD. For example, a package of inositol-containing cookies may include indicia to that effect. A package of inositol-containing comestible units may further include printed indicia communicating that the units and/or high doses of inositol may cause diarrhea and/or that the preferred amount of inositol for a given ASD patient is to be provided in one unit less than the number of units daily that induce diarrhea in a given ASD patient.
Aside from cookies, the inositol-containing comestible units may be brownies, pastries, doughnuts, graham crackers, candies, cakes, chocolates, cereal bars, pies, wafers, muffins, cupcakes, gummies and lollipops, or other sweet food units.
As discussed above, combination therapy is the subject of Applicant's earlier filed patent applications, including U.S. Pat. Pub. 2014/0309271 (the “'271 application”). In one embodiment, the inositol-containing comestible units of the present invention may be administered in combination with an alpha-2 adrenergic agonist in an extended release dosage form, to treat ASD, according to methods disclosed in the '271 application.
It is within the ability of a psychiatrist of ordinary skill to assess each of the various symptoms and diagnostic criteria for ASD generally and for other symptoms associated with ASD described herein, in a clinical setting, using his or her training and experience. Optionally, a psychiatrist may desire to measure these symptoms and criteria using a recognized quantitative scale in the field of ASD, optionally the Social Responsiveness Scale (“SRS”). The Social Responsiveness Scale (SRS) (Constantino, J. et al., J Dev Behav Pediatr, 21:2-11 (2000); Constantino, J. et al., J Autism Dev Disord., 3:427-433 (2003)) is a norm-referenced, 65-item report questionnaire developed to measure social behaviors, including social awareness, social information processing, reciprocal social communication, and social anxiety, in both clinical and non-clinical populations. It is designed for use with children ages 4 through 18. The SRS items measure ASD symptoms in the domains of social awareness, social information processing, reciprocal social communication, social anxiety/avoidance, and stereotypic behavior/restricted interests. Each item is scored from 1 (not true) to 4 (almost always true). Scores are obtained for five treatment subscales: Social Awareness (e.g., “Is aware of what others are thinking or feeling”), Social Cognition (e.g., “Doesn't recognize when others are trying to take advantage of him or her”), Social Communication (e.g., “Avoids eye contact or has unusual eye contact”), Social Motivation (e.g., “Would rather be alone than with others”), and Autistic Mannerisms (e.g., “Has an unusually narrow range of interests”).
Aspects of the present invention are further explained by the following examples which should not be construed by way of limiting the scope of the present invention.
Cookies are made to contain 2,700 mg of inositol power each (¾ tsp of FREEDA® brand inositol powder having a concentration of 900 mg per ¼ tsp). The inositol acts as a sweetener which allows reduction in sugar content of each cookie.
It is found that preferred dosing of these 2,700 mg inositol cookies is two to four cookies two or three times daily for ASD patients, titrated until a given ASD patient reaches his/her diarrhea threshold. It is found that these inositol-containing cookies at these doses are effective in treating symptoms of ASD, including part B of the DSM 5.0 definition of ASD and emotional lability/irritability.
Optionally, the cookies are taken in combination with therapeutically effective amounts of extended release clonidine (KAPVAY®) or extended release guanfacine (INTUNIV®).
Cookies are made to contain 3,600 mg of inositol power each (1 tsp of FREEDA® brand inositol powder having a concentration of 900 mg per ¼ tsp). The inositol acts as a sweetener which allows reduction in sugar content of each cookie.
It is found that preferred dosing of these 3,600 mg inositol cookies is two to three cookies two times daily for ASD patients, titrated until a given ASD patient reaches his/her diarrhea threshold. It is found that these inositol-containing cookies at these doses are effective in treating symptoms of ASD, including part B of the DSM 5.0 definition of ASD and emotional lability/irritability.
Optionally, the cookies are taken in combination with therapeutically effective amounts of extended release clonidine (KAPVAY®) or extended release guanfacine (INTUNIV®).
In a study, a group of 24 ASD patients are given the cookies of Example 2 above, according to the dosing guidelines described therein (i.e., titrated to each patient's diarrhea threshold). After three weeks, it is observed that 22 out of the 24 patients' ASD symptoms are alleviated, particularly in the domains of part B of the DSM 5.0 definition of ASD and emotional lability/irritability.
The 24 patients are then separated into two groups. Twelve of these patients continue on the same treatment as before. The other twelve are, without their knowledge, switched to cookies that appear and taste essentially identical to the inositol-containing cookies, except that these new cookies (the placebo cookies) contain no inositol. After two weeks, the treated group continues to respond as well as it had after the first three weeks of the study. However, the patients in the placebo group revert back to their pre-treatment symptomology, and in some cases worse than their pre-treatment symptomology.
This example shows how, in one aspect, the invention may provide an effective tool in a clinical trial to render a switch from inositol-containing cookies to placebo cookies imperceptible (in taste, appearance, texture, etc.) to a patient.
Example 4 of the '271 application describes a retrospective study of medical charts of the Applicant's ASD patients who, in addition to having the core symptoms of ASD, also had symptoms associated with ASD (impulsivity, concentration deficit or attention deficit and emotional lability/irritability). That example presented data showing superior efficacy of Applicant's combination therapy in treating ASD compared to using either agent alone. The present example isolates the data from Example 4 of the '271 application relating to use of high doses of inositol as a monotherapy for ASD.
175 of these patients had initially received some form of medication (not treatment according to the present invention) or had been given psychotherapy without medication. Of these, 22% responded in some way to the medication and 17% responded in some way to psychotherapy alone. 77% of those on one or more of the following medications experienced adverse effects: stimulants, SSRI's, SNRI's, mood stabilizers, antipsychotics, benzodiazepines and immediate release alpha-2 agonists.
66 of the study patients were given high doses of inositol as a monotherapy. 62 of the 66 patients (94%) showed improvement in part B of the DSM 5.0 definition of ASD and the associated ASD symptom of emotional lability/irritability. 12% of inositol monotherapy patients experienced a minimal side effect of diarrhea, which was substantially resolved with dosage reduction.
While combination therapy was certainly shown to be superior, monotherapy using high doses of inositol was still shown to be effective in treating some symptoms in ASD.
A study is conducted involving 28 patients who qualify for an ASD diagnosis. In a first phase, these patients are divided into two groups: a drug group (16 patients) that receives therapeutic amounts of inositol (average from 9,000 mg to 18,000 mg per day) in an oral powder dosage form for two weeks; and a placebo group (12 patients) that receives a confectionary sugar-based powdered placebo (intended to represent inositol) for two weeks. Neither group receives any other psychiatric drug during the two weeks of drug or placebo administration. After those two weeks, the progress of the patients in the two groups are measured according to the SRS. It is found that all 16 patients in the drug (inositol alone) group show clinically meaningful reduction in the restricted areas of interest and repetitive behaviors subscale of the SRS. However, none of the 12 patients in the placebo group show any measurable reduction in the restricted areas of interest and repetitive behaviors subscale of the SRS.
There is an urgent public health need for the mental health community to understand that a significant percentage of ASD patients respond exceptionally well with minimal side effects to inositol in combination with INTUNIV® or KAPVAY®. It is for this reason that Applicant has filed patent applications directed to this combination therapy (e.g., the '271 application), which, in Applicant's experience, is clearly superior in efficacy in treating ASD than either agent alone. However, given the realities of regulatory approval necessary to bring this combination therapy to market, it is not anticipated that the urgent public health need will be met swiftly. In the meantime, high doses of inositol according to the present invention, particularly in pre-dosed comestible units, provide a safe and effective means to treat some symptoms of ASD.
While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
