[0001] This application claims the benefit of and priority to U.S. Provisional Application No. 63 / 524,735, filed July 3, 2023, which is hereby incorporated by reference in its entirety for all purposes.BACKGROUND

[0002] 3,4-Methylenedioxymethamphetamine (MDMA) is an amphetamine analog targeting neurotransmitter systems within the brain. MDMA is a ring-substituted derivative of phenethylamine with a chiral center. There are two stereoisomers of MDMA: S(+)-MDMA and R(-)-MDMA. Phenethylamines including MDMA are known to have psychoactive and stimulant effects, and MDMA has been evaluated clinically for a number of potential therapeutic indications. Depending on the indication, the activity and acute effects of the different MDMA compositions (R(-) enriched, S(+) enriched, and racemic mixture) is unpredictable and can vary widely. In some cases, a specific form or forms of MDMA can be associated with specific adverse effects.

[0003] The term aggression response behavior refers to a number actions and / or personality traits that can result in physical and psychological harm to oneself as well as others. As such, effective compositions that can manage, modulate, or otherwise reduce aggression response are of great importance.

[0004] The present disclosure provides compositions and methods that are effective in modulating aggression response by providing enantiomerically enriched compositions of MDMA, i.e., compositions comprising specific ratios of the R(-) and S(+) enantiomers (up to enantiomerically pure R(-)-MDMA or S(+)-MDMA).SUMMARY

[0018] Racemic MDMA, consistent with its known 5 -HT -increasing activity, has been reported to modulate aggression response behaviors in mammals (see, e.g., Kirilly E, et al., Acute and long-term effects of a single dose of MDMA on aggression in Dark Agouti rats. Int J Neuropsychopharmacol . 2006 Feb;9(l):63-76.), however racemic MDMA may exert unwanted side effects. The efficacy of the individual MDMA enantiomers R(-) or S(+) MDMA in modulating or reducing aggression has not been characterized. Accordingly, the present disclosure provides compostions and methods for treating or reducing aggression in a subject in need thereof with enantiomerically enriched or pure MDMA compositions.

[0019] For convenience, certain terms employed in the specification, examples and claims are collected here. Unless defined otherwise, all technical and scientific terms used in this disclosure have the same meanings as commonly understood by one of ordinary skill in the art to which this disclosure belongs.I. Definitions

[0020] The term “about” when immediately preceding a numerical value means a range (e.g., plus or minus 10% of that value). For example, “about 50” can mean 45 to 55, “about 25,000” can mean 22,500 to 27,500, etc., unless the context of the disclosure indicates otherwise, or is inconsistent with such an interpretation. For example, in a list of numerical values such as “about 49, about 50, about 55, ... ”, “about 50” means a range extending to lessAtty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008) than half the interval(s) between the preceding and subsequent values, e.g., more than 49.5 to less than 50.5.

[0021] The terms “administer,” “administering” or “administration” as used herein refer to administering a compound or pharmaceutically acceptable salt of the compound or a composition or formulation comprising the compound or pharmaceutically acceptable salt of the compound to a subject.

[0022] The terms “aggression,” “aggression response,” “aggressive behavior(s),” and / or “aggression response behavior(s),” are used interchangeably and refer to one or more intentional or unintentional observable or reported acts, thoughts, or responses characterized as inflicting discomfort, damage, or other harm upon an object, one’s self, or another individual. As used herein, aggression covers a range of behavioral disturbances or disorders, including, but not limited to, irritability, impulsivity, hypervigilance and hyperarousal. Aggression or an aggression response may occur reactively or without provocation. In humans, aggression can be caused by various factors and stimuli such as, for example, environmental triggers or by disorders or diseases giving rise to or associated with aggressive behavior or feelings that can give rise to aggression and / or aggressive behavior (e.g., emotions like fear, frustration, anger, feelings of stress, disrespect, dominance, or pleasure). Aggression can manifest in a variety of forms, which may be expressed physically, verbally, or non-verbally and can include predatory and anti -predatory aggression, defensive aggression, dominance aggression, resident-intruder aggression, maternal aggression, species specific aggression, sex- related aggression, territorial aggression, isolation-induced aggression, irritable aggression, and brain-stimulation-induced aggression. Human aggression may be generally classified with two subtypes: (1) controlled-instrumental subtype (purposeful or goal oriented); and (2) reactive-impulsive subtype (often elicits uncontrollable actions that are inappropriate or undesirable). As such, aggression and / or aggression response(s) may be associated with, or identified and / or diagnosed by, any symptoms that are commonly associated with feelings of aggression or aggressive behaviors. Some non-limiting examples include, feelings of anger, frustration, hypervigilance, or fear or combinations thereof, violent behavior, abusive language, functional impairment (e.g., personal and / or professional functional impairment), degradation or impairment of social association, connection, or affiliation between the subject aggressor and one or more persons (i.e., impairment / degradation of interpersonal relationships; difficulty concentrating, thinking, or performing daily tasks, and the like). Aggression and / or aggression response behavior(s) can be identified using any technique, test, or evaluationAtty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008) generally known in the art that can provide a general rating scale of such behavior over a period or several periods of time. Non-limiting examples include observational diagnoses (e.g. clinical or non-clinical diagnosis) that can evaluate one or more categories of behavior (e.g., verbal aggression, aggression against inanimate objects, aggression against oneself, and aggression against others). In some non-limiting embodiments aggression and / or aggression response can be evaluated using an aggression scale such as, for example, the Modified Overt Aggression Scale, (“MOAS”).

[0023] The terms “effective amount” and “therapeutically effective amount” are used interchangeably in this disclosure and refer to an amount of a compound, or a salt thereof, (or pharmaceutical composition containing the compound or salt) that, when administered to a subject, is capable of performing the intended result.

[0024] The term “MDMA,” without any further description, refers to a mix of S(+)-3,4- methylenedi oxymethamphetamine and R(-)-3,4-methylenedi oxymethamphetamine, including recemic MDMA. MDMA has a chiral center and two stereoisomers, S(+)-MDMA and R(-)- MDMA. The enantiomers have been shown to impact the monoaminergic targets of MDMA differently and can have different toxicologic and pharmacologic properties, but not in a predictable manner. As described herein, enantiomerically enriched or enantiomerically pure MDMA comprise an unequal amount of the R(-)-MDMA and S(+)-MDMA enantiomers and can range from 50.1% enriched in one enantiomer and up to about an enantiomerically pure form of the enantiomer (e.g., 99.5% or greater (i.e., 100%) enrichment in one enantiomer).

[0025] The phrase “pharmaceutically acceptable” as used herein refers to those compounds, materials, compositions, and / or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit / risk ratio.

[0026] The term “salts” as used herein embraces pharmaceutically acceptable salts commonly used to form alkali metal salts of free acids and to form addition salts of free bases. Salts include those obtained by reacting the active compound functioning as a base, with an inorganic or organic acid to form a salt, for example, salts of hydrochloric acid, sulfuric acid, phosphoric acid, methanesulfonic acid, camphorsulfonic acid, oxalic acid, maleic acid, succinic acid, citric acid, formic acid, hydrobromic acid, benzoic acid, tartaric acid, fumaric acid, salicylic acid, mandelic acid, carbonic acid, etc. Base addition salts include but are not limited to, ethylenediamine, N-methyl-glucamine, lysine, arginine, ornithine, choline, N,N'-Atty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008) dibenzylethylenediamine, chloroprocaine, diethanolamine, procaine, N- benzylphenethylamine, diethylamine, piperazine, tris-(hydroxymethyl)-aminomethane, tetramethylammonium hydroxide, triethylamine, dibenzylamine, ephenamine, dehydroabietylamine, N-ethylpiperidine, benzylamine, tetramethylammonium, tetraethylammonium, methylamine, dimethylamine, trimethylamine, ethylamine, basic amino acids, e. g., lysine and arginine di cyclohexylamine and the like. Examples of metal salts include lithium, sodium, potassium, magnesium, calcium salts and the like. Examples of ammonium and alkylated ammonium salts include ammonium, methylammonium, dimethylammonium, trimethylammonium, ethylammonium, hydroxyethylammonium, diethylammonium, butylammonium, tetramethylammonium salts and the like. Examples of organic bases include lysine, arginine, guanidine, diethanolamine, choline and the like. Those skilled in the art will further recognize that acid addition salts may be prepared by reaction of the compounds with the appropriate inorganic or organic acid via any of a number of known methods.

[0027] The term “therapeutic effect” as used herein refers to a desired or beneficial effect provided by the method and / or the composition.

[0028] The term “treating” as used herein with regard to a subject, refers to improving at least one symptom of the subject's disorder. Treating can be improving, or at least partially ameliorating a disorder or an associated symptom of a disorder.II. Compositions

[0040] In embodiments, the present disclosure provides methods of treating aggression that is associated with an anxiety disorder. In embodiments, the anxiety disorder is one or more of generalized anxiety disorder, phobia, social anxiety disorder (SAD), social phobia, panic disorder, panic attack, post-traumatic stress disorders (PTSD), separation anxiety disorder, selective mutism, agoraphobia, or an anxiety disorder induced by a substance / medication or due to another medical condition. Psychopathologies such as anxiety- and depression-related disorders are often characterized by impaired social behaviors including excessive aggression and violence. Excessive aggression and violence likely develop as a consequence of generally disturbed emotional regulation, such as abnormally high or low levels of anxiety. Previous studies indicate an overlap between brain circuitries and neurochemical systems regulating aggression and anxiety. Neumann ID, et al., Aggression and anxiety: social context and neurobiological links. Front Behav Neurosci . 2010 Mar 30;4: 12.

[0041] In embodiments, the present disclosure provides methods of treating aggression that is associated with social anxiety disorder (SAD). SAD, also known as social phobia, is characterized by a marked and persistent fear of one or more social or performance situations in which the person is exposed to unfamiliar people or to possible scrutiny by others (AmericanAtty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008)Psychiatric Association, 1994a). Exposure to the feared situation almost invariably provokes anxiety, which may approach the intensity of a panic attack. The feared situations are avoided or endured with intense anxiety or distress. The avoidance, anxious anticipation, or distress in the feared situation(s) interferes significantly with the person’s normal routine, occupational or academic functioning, or social activities or relationships. Recent research has revealed a subtype of individuals with social anxiety disorder (SAD) who tend to display relatively high amounts of aggression and experience more severe social anxiety and dysfunction compared to individuals in the prototypical SAD group.

[0141] The following examples are provided to further illustrate the embodiments of the present disclosure but are not intended to limit the scope of the embodiments. While they are typical of those that might be used, other procedures, methodologies, or techniques known to those skilled in the art may alternatively be used.Example 1: MDMA forms and effect on aggression response

[0142] The efficacy of the compositions disclosed herein including racemic MDMA and enantiomerically pure forms of MDMA (S(+)-MDMA and R(-)-MDMA) were evaluated for effects on aggression behaviors. Aggressive behaviors in mice were measured using the Resident-Intruder Animal Model. The resident-intruder (RI) test was used to observe offensive responses, typically by using individual housing to induce inter-male aggression in socially- isolated mice. This is a behavior test used to assess the social behavior and aggression in rodents. This test used biting to signify an act of aggression.Atty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008)

[0143] Methods: Male mice (aged 10-13 weeks at the beginning of the experiments) were allowed to acclimate to environmental conditions for at least 5 days prior to experimentation. The resident animals were individually housed in polycarbonate cages (floor area = 549 cm2) and the intruder animals were housed in groups of 4-10 in polysulfone cages (floor area = 1500 cm2) under standard conditions (room temperature at 22±2°C; hygrometry at 55±10%; light / dark cycle at 12h / 12h; air circulation at 15-20 volumes / hour; water and food ad libitum).

[0144] Enrichment for intruder animals consisted of the presence in the cage of cellulose slices and wooden briquettes. Small structures (house type) were added in order to promote nesting. For the resident animals, the enrichment consisted of wooden briquettes. The intruder animals were numbered by marking their tail using indelible markers.

[0145] Four independent dose-response experiments were conducted using male NMRI mice as either resident or intruder mice. (Janvier Labs, Saint-Berthevin, France).

[0146] Independent dose-response experiments evaluated the following MDMA compositions formulated in 0.9% NaCl and administered intraperitoneally (IP). All MDMA was sourced from Curia Global Inc., Albany, NY. Racemic MDMA HC1 at 3, 5.6, and 7.8 mg / kg free base; R(-)-MDMA HC1, at 10, 17 and 30 mg / kg free base; R(-)-MDMA HC1 at 1, 3 and 10 mg / kg free base; or S(+)-MDMA HC1 at 1, 3, 10 mg / kg free base was administered.

[0147] Doses were based on the molecular weight of the free base (correction factor for racemic, R(-) and S(+)-MDMA = 1.189). Risperidone was included in each experiment as a positive reference (0.06 mg / kg; Carbosynth Limited, Compton, UK; ref. FR27737). Risperidone was formulated in 0.9% NaCl with a few drops of 0.1N HC1 and administered subcutaneously (SC). Vehicle, test article or risperidone was administered once, 30 min before Test 3. The volume of administration was 10 mL / kg body weight for IP or SC administration.

[0148] The resident mice were kept isolated in their individual home-cage throughout the 3-week experiment. One week after the beginning of the isolation period, two pre-tests (Test 1 and Test 2), spaced by one week, were performed in order to detect the level of aggressivity of each resident. One week after Test 2, drug administration was performed in Test 3.

[0149] At each RI test, the animals to be tested were placed in an experimental room at least 30 minutes before testing. During the 3 RI tests, each socially housed intruder was confronted to one resident for a session of 5 minutes in the resident’s home-cage. After the test, intruder mice were returned to their social group. Latency to first attack, number of attacks and total duration of attacks induced by the resident towards the intruder were recorded by a trainedAtty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008) observer using a timer and a counter. An attack was defined as biting the intruder. For each RI test, the resident interacted with a new intruder.

[0150] During Test 1 and Test 2, if a resident was attacked by the intruder, both mice were excluded from the study and not used again. During Test 2, only resident mice displaying at least one attack were included in Test 3. The aggressivity level of each resident mouse was evaluated based on the 3 recorded parameters. Animals that met the inclusion criterion were randomly allocated to experimental groups to ensure similar aggression levels prior to treatment, with a maximum of 12 mice per treatment condition.

[0151] The experimenter scoring the behaviour was not aware of the animal treatment. Testing was performed from 8.00 a.m. to 1.00 p.m. During Tests 1, 2 and 3, the following parameters were measured for resident mice: Latency to first attack(s), Number of attacks, Total duration of attack(s).

[0152] All parameters were analyzed at Biotrial with GraphPad Prism® software (current version). The number of attacks, latency to first attack and total duration of attacks during Test 3 were analyzed as follows: Comparison of the vehicle-treated group versus the Test Item- treated groups using a Kruskal -Wallis test. When group effect was significant, a Mann- Whitney test was used to compare each test article condition versus vehicle. Comparison of vehicle-treated group versus risperidone-treated group utilized a Mann-Whitney test. P<0.05 was set as the level of significance.Example 1.1 - Effects of racemic MDMA

[0153] A single administration of racemic MDMA significantly and dose-dependently reduced aggressive behaviors, as measured by latency to first attack, number of attacks and total duration of attack, in socially-isolated NMRI mice in the resident-intruder test at all tested doses (Figure 1; *p<0.05, **p<0.01, ***p<0.001 vs. Vehicle). As expected, a single administration of the positive reference compound, 0.06 mg / kg risperidone, significantly decreased aggressive behaviors, as measured by latency to first attack, the number of attacks and total duration of attack, validating the robustness of the experiment (FIG. 1; **p<0.01, ***p<0.001 vs. Vehicle).

[0154] FIG. 1 depicts the effects of racemic MDMA (3, 5.6 and 7.8 mg / kg i.p.) on aggressive behaviors in socially-isolated male NMRI mice (N=12).Atty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008)Example 1.2 - Effects of R(-)-MDMA

[0155] A single administration of R(-)-MDMA (administered i.p., at 10, 17 and 30 mg / kg) significantly reduced aggressive behavior, as measured by latency to first attack, number of attacks and total duration of attack, in socially-isolated NMRI mice in the resident-intruder test at all tested doses (FIG. 2; ***p<0.001 vs. Vehicle). Single administration of the positive reference compound, 0.06 mg / kg risperidone, significantly decreased aggressive behavior, as measured by latency to first attack, the number of attacks and total duration of attack, validating the robustness of the experiment (FIG. 2; ***p<0.001 vs. Vehicle).

[0156] FIG. 2 depicts the effects of R(-)-MDMA (administered i.p., at 10, 17 and 30 mg / kg) on aggressive behavior in socially-isolated male NMRI mice (N=12).Example 1.3 - Effects of R(-)-MDMA (lower doses)

[0157] A single administration of R(-)-MDMA at lower doses (administered i.p. at 1, 3 and 10 mg / kg) significantly reduced aggressive behavior, as measured by latency to first attack, the number of attacks and total duration of attack, in socially-isolated NMRI mice in the residentintruder test at 3 and 10 mg / kg (FIG. 3; **p<0.01, ***0.001 vs. Vehicle). A single administration of the positive reference compound, 0.06 mg / kg risperidone, significantly decreased aggressive behaviors, as measured by number of attacks and total duration of attack (FIG. 3; ***p<0.001 vs. Vehicle). However, the effect of 0.06 mg / kg risperidone on latency to first attack did not achieve statistical significance compared to vehicle (FIG. 3; p=0.0532). Overall, the significant effects of 0.06 mg / kg risperidone on 2 out of 3 measures of aggressive behavior validates the robustness of the experiment.

[0158] FIG. 3 depicts the effects of R(-)-MDMA (administered i.p. at 1, 3 and 10 mg / kg) on aggressive behavior in socially-isolated male NMRI mice (N=12).Example 1.4 Effects ofS(+ )-MDMA

[0159] A single administration of S(+)-MDMA (administered i.p. at 1, 3 and 10 mg / kg) significantly reduced aggressive behaviors, as measured by latency to first attack, the number of attacks and total duration of attack, in socially-isolated male NMRI mice in the residentintruder test at 1, 3 and 10 mg / kg (FIG. 4; *p<0.05, **p<0.01, ***p<0.001 vs. Vehicle). A single administration of the positive reference compound, 0.06 mg / kg risperidone, significantly decreased aggressive behaviors, as measured by latency to first attack, the number of attacksAtty Ref. ATAI-092 / 01 WO 338067-2474 (EMP-008) and total duration of attack, validating the robustness of the experiment (FIG. 4; ***p<0.001 vs. Vehicle).

[0160] FIG. 4 depicts the effects of S(+)-MDMA (i.p. administration at 1, 3 and 10 mg / kg) on aggressive behavior in socially-isolated male NMRI mice (N=12).

[0161] This study examined the effect of enantiomerically pure forms of MDMA (i.e., R(- )-MDMA and S(+)-MDMA) on aggression behaviors, using the mouse resident-intruder test. Given that R(-)-MDMA has known differential activity for SERT inhibition and 5-HT release (and consequently stimulation of 5-HT1 A and 5-HT1B receptors) when compared to both S(+)- MDMA and racemic MDMA, one of skill may expect that the potency and magnitude of the anti-aggression effects of R(-)-MDMA are lower than those of S(+)-MDMA and racemic MDMA.

[0162] The results indicate similarities among racemic MDMA and each of its enantiomers, R(-) and S(+)-MDMA, in that all forms exhibit anti-aggressive effects in a model of socially-isolated male mice. Notably, the data identifies a minimal effective dose for R(-)- MDMA (i.e., 3 mg / kg i.p.), but does not insufficiently define minimal effective doses for racemic MDMA (i.e., <3 mg / kg i.p.) or S(+)-MDMA (i.e., <1 mg / kg i.p.).

[0163] These data lend additional support to the continued development of enantiomerically pure or enantiomerically enriched forms of MDMA for the treatment of disorders that are accompanied by increased aggression, irritability, impulsivity, hypervigilance and / or hyperarousal.Example 2- Clinical Evaluation of the effects of enantiomerically enriched or pure MDMA on aggression
