Example 1: Effects of THC, CBD, CBN Compositions on Sleep

(26) A study was conducted to measure the effects of compositions comprising cannabinoids THC, CBD, CBN on sleep latency and sleep duration using a well-established mouse model-based sleep test called the Loss Of Righting Reflex (LORR) test. The study identified compositions that exhibited positive effect in the aforementioned model.

(27) The LORR test was used to study the effect of cannabinoid compositions on pentobarbital-induced sleep, and was conducted as follows: 30 minutes prior to sedation/sleep induction with an intraperitoneal (IP) injection of Pentobarbital (30 or 40 mg/kg), mice (7-week-old male Balb/C mice) were weighed and treated with an IP injection of: vehicle (Ethanol:Cremophor:Saline, volume ratio 1:1:18) as negative control; diazepam (3 mg/kg) as positive control; or with one of a plurality of test cannabinoid compositions in accordance with embodiments of the disclosure (described below). Observation of the mouse began immediately after administration of Pentobarbital. Once the mouse was asleep (as determined by the loss of righting reflex), it was transferred to a home cage and placed on its back, and observation was continued. Mice were considered awake when they could successfully upright themselves (all four feet in contact with the surface). Once a mouse righted itself, it was placed on its back once more and allowed to right a second time for confirmation. For the negative control group (vehicle treatment), mean sleep onset was 8-12 min and mean sleep duration was 25-45 min. For the positive control group (diazepam treatment), mean sleep onset was 3-5 min and mean sleep duration was 60-90 min. The 3 mg/kg dose of diazepam used in the mice is equivalent to approximately 10-12 mg dose in human subjects.

(28) Test cannabinoid compositions were prepared using cannabinoids purified from whole cannabis plant extract, having >95% purity. The compositions were prepared in the aforementioned vehicle.

(29) The test cannabinoid compositions contained two or more of THC at a dosage between 0.05 mg/kg (mg cannabinoid/kg weight of subject) and 3 mg/kg, CBD at a dosage of between 4 mg/kg and 150 mg/kg, and CBN at a dosage of between 10 mg/kg and 80 mg/kg. The following compositions were tested:

(30) TABLE-US-00001 TABLE 1 Dosage in mg/kg Composition # THC CBD CBN 111 0.05 4 10 131 0.05 150 10 113 0.05 4 80 221 0.5 40 10 311 3 4 10 122 0.05 40 20 121 0.05 40 10 123 0.05 40 80 021 0 40 10 321 3 40 10

(31) The cannabinoid ratios of the tested compositions can be expressed as follows, with the relative concentration of THC arbitrarily set at 1 or 0, for ease of comparison of the relative amounts of the cannabinoids between the different compositions:

(32) TABLE-US-00002 TABLE 2 Relative dosage ratio Composition # THC CBD CBN 111 1 80 200 131 1 3000 200 113 1 80 1600 221 1 80 20 311 1 1 3 122 1 800 400 121 1 800 200 123 1 800 1600 021 0 4 1 321 1 13 3

(33) Alternatively, the cannabinoid ratios of the tested compositions can be expressed as follows, with the relative concentration of CBD arbitrarily set at 1:

(34) TABLE-US-00003 TABLE 3 Relative dosage ratio Composition # THC CBD CBN 111 0.0125 1 2.5 131 0.00033 1 0.07 113 0.0125 1 20 221 0.0125 1 0.25 311 0.75 1 2.5 122 0.00125 1 0.5 121 0.00125 1 0.25 123 0.00125 1 2 021 0 1 0.25 321 0.075 1 0.25

(35) The study included 12 mouse subjects treated with vehicle, 12 subjects treated with diazepam, and 6 subjects treated for each test cannabinoid composition.

(36) FIG. 1 shows a bar graph and data table of the mean sleep onset latency for each tested composition, as a percentage of the mean sleep onset latency from the time of pentobarbital administration of subjects treated with diazepam. diazepam treated animals, as expected, fell asleep substantially faster following pentobarbital administration compare to those treated with vehicle (250% of latency with diazepam treatment). Animals treated with test cannabinoid compositions 111 and 021 exhibited sleep onset latencies similar to vehicle treatment (305% and 225% of diazepam treatment, respectively). Animals treated with the other compositions of 131, 113, 221, 311, 122, 121, 123, and 321 exhibited sleep onset latencies similar to diazepam treatment (between 140% and 90% of diazepam treatment).

(37) FIG. 2 shows a bar graph and data table of the mean total sleep duration for each tested formulation, as a percentage of the mean total sleep duration of subjects treated with diazepam.

(38) Diazepam treated animals, as expected, slept for a longer duration following pentobarbital administration compare to those treated with vehicle (37% sleep duration compared to diazepam treatment). Many of the test cannabinoid compositions were even more effective than diazepam in prolonging pentobarbital-induced sleep—compositions 131, 221, 122, 121, 123, 021 and 321 each exhibited a mean total sleep duration that was substantially longer than diazepam-treated controls (between 214% and 563% of diazepam treatment).

(39) The pentobarbital dosing regimen induced sleep in only a portion of the vehicle-treated negative control mice. FIG. 3 shows a floating bar graph and data table of the percentage of mice in each treatment that fell asleep after pentobarbital administration. As shown in FIG. 3, 33% of vehicle treated mice fell asleep after pentobarbital treatment. Diazepam treatment enhanced the sleep-inducing effect of pentobarbital, such that 92% of diazepam-treated mice fell asleep after pentobarbital administration. Many of the test cannabinoid compositions were even more effective than diazepam in enhancing the sleep-inducing property of pentobarbital—compositions 131, 221, 122, 121 and 123 each had a 100% of mice in the treatment group fall asleep.

(40) During the full course of pentobarbital-induced sleep, some of the subjects briefly woke up then fell back asleep, before fully waking up. FIG. 4 shows a bar graph and a data table showing the percentages of subjects in each test group that had 0, 1 or 2 brief, temporary (“transient”) awakenings before fully awaking from the pentobarbital-induced sleep. When a mouse righted itself after pentobarbital treatment, the mouse was manually returned to a supine position to encourage the mouse to go back to sleep. If the mouse fell back asleep within three tries of being placed in the supine position, the mouse was evaluated as having not woken up. If the mouse did not return to sleep within the above three attempts, then the animal was allowed on its feet for 5-10 minutes, after which the mouse was returned to a supine position a maximum of three more times. If the mouse returned to sleep, then the brief waking episode was scored as a transient awakening. If the mouse still failed to go back to sleep, then the mouse was scored as being fully awake as of the time it righted itself.

(41) Diazepam-treated animals, as expected, exhibited fewer transient awakenings compared to vehicle-treated negative controls. diazepam-treated subjects had lower incidence of transient awakenings during the respective sleep sessions. 60% of vehicle-treated subjects exhibited one transient awakening and 40% stayed asleep during the pentobarbital-induced sleep session. By contrast, out of the diazepam-treated subjects, 25% of the subjects woke up once and 75% stayed asleep during the sleep session. Many of the test cannabinoid compositions were as effective or more effective than diazepam in reducing the number of transient awakenings during the sleep session—groups treated with compositions 113, 311, 122, 221 and 321 had a higher incidence of sleep sessions with no transient awakenings (between 83% and 100%) compared to diazepam-treated controls.

(42) Out of the test cannabinoid compositions tested using the LORR method, composition 122 had an especially favorable combination of sleep-enhancing properties. Subjects treated with a composition 122 had a mean total sleep duration 2.5-fold longer compared to diazepam controls while having fewer transient awakenings during the sleep session (83% of the group had no transient awakenings during the session compared 75% with diazepam treatment), and similar sleep onset latency compared to diazepam treatment.

(43) Other examples of compositions with notably favorable combinations of sleep-enhancing properties include composition 131, composition 121, and composition 123.

(44) Subjects treated with composition 123 had a mean total sleep duration 5.6-fold longer compared to diazepam controls and slightly shorter sleep onset latency compared to diazepam treatment. Composition 123 treatment resulted in having substantially more transient awakenings during the sleep session (17% of the group had no transient awakenings during the session compared 75% with diazepam treatment). Without being bound by theory, the increase in the incidence of transient awakenings indicates changes in the sleep architecture associate with this composition, in that while other compositions may induce deeper sleep stages the composition 123 induces relatively shallow sleep with sharp transition between sleep stages that observationally result with apparent awakening of the subject. Alternatively, and without being bound by theory, the increase in the incidence of transient awakenings in mice treated with composition 123 is reflective of the substantial increase in the duration of the sleep session, in which transient awakenings as measured per unit time (as opposed to during the entire sleep session). Mice treated with composition 123 exhibited, on average, a 3.3-fold increase in incidence of a transient awakening during their respective sleep sessions compared to diazepam-treated subjects (83% incidence of a transient awakening in composition 123 mice compared to 25% in diazepam-treated mice). However, this increase in mean incidence of transient awakening is offset by the 5.6-fold increased total sleep duration for composition 123-treated mice. As such, the mean incidence of transient awakening per unit time of sleep session duration is lower in composition 123-treated mice.

(45) Subjects treated with composition 121 had a mean total sleep duration 2.1-fold longer compared to diazepam controls while having only slightly more awakenings during the sleep session (50% of the group had no awakenings during the session compared 75% with diazepam treatment), and slightly longer sleep onset latency of 1.2-fold longer compared to diazepam treatment.

(46) Subjects treated with composition 131 had a mean total sleep duration 3.2-fold longer compared to diazepam-treated controls while having only slightly more awakenings during the sleep session (50% of the group had no awakenings during the session compared 75% with diazepam treatment), and only slightly longer sleep onset latency of 1.4-fold longer compared to diazepam treatment.

(47) Without being bound by theory, differences between composition 021 and composition 121 with regard to sleep onset latency and percent of mice that fell asleep (FIGS. 1 and 3) seem to indicate that the presence of THC in small amounts relative to CBD and CBN increases the sleep-enhancing effect of the compositions relative to composition with CBD and CBN alone. Increase of amount of THC relative to CBD and CBN, as in composition 321 decrease total sleep duration in comparison to composition 121.

Example 2: Further Effects of THC, CBD, CBN Compositions on Sleep

(48) The LORR model was performed as in Example 1, using compositions described in table 4. The test cannabinoid compositions contained two or more of THC at a dosage between 0.05 mg/kg and 0.1 mg/kg, CBD at a dosage of between 20 mg/kg and 40 mg/kg, and CBN at a dosage of between 1 mg/kg and 15 mg/kg. The following compositions were tested:

(49) TABLE-US-00004 TABLE 4 Dosage in mg/kg Composition # THC CBD CBN 2 2 0.5 0.5 40 1 1 1.5 0.5 0.05 20 1 1.5 1.5 1 0.1 20 10 1 1.5 1 0.05 20 10 1.5 2 1.5 0.1 40 15 1.5 2 1 0.1 40 10 1 2 1.5 0.05 40 15 2 2 1 0.5 40 10 1.5 2 1.5 0.1 40 15

(50) The cannabinoid ratios of the tested compositions are expressed with relative concentration of CBD set at 1.

(52) The cannabinoid ratios of the tested compositions are expressed with relative concentration of THC set at 1 are shown in table 6.

(53) TABLE-US-00006 TABLE 6 Relative dosage ratio Composition # THC CBD CBN 2 2 0.5 1 80 2 1 1.5 0.5 1 400 20 1.5 1.5 1 1 200 100 1 1.5 1 1 400 200 1.5 2 1.5 1 400 150 1.5 2 1 1 400 100 1 2 1.5 1 800 300 2 2 1 1 80 20 1.5 2 1.5 1 400 150

(54) The study included 12 mouse subjects treated with vehicle, 14 subjects treated with diazepam, 6 subjects treated for each test cannabinoid composition and 4 subjects in each terpenes-only group.

(55) FIG. 5 shows a bar graph and data table of the mean sleep onset latency for each tested composition, as a percentage of the mean sleep onset latency from the time of pentobarbital administration of subjects treated with diazepam. The vehicle-treated animals showed sleep latency of 384% relative to the diazepam-treated animals. All of the compositions comprising THC, CBD and CBN showed improved sleep onset latency in comparison to vehicle. Animals treated with test compositions 1.5 2 1.5, 1.5 2 1, 1 2 1.5 and 2 2 1, showed the best results, having mean sleep onset latency of less than 150% relative to diazepam.

(56) FIG. 6 shows a bar graph and data table of the mean total sleep duration for each tested composition, as a percentage of the mean total sleep duration of subjects treated with diazepam. Diazepam treated animals, as expected, slept for a longer duration following pentobarbital administration compare to those treated with vehicle only (24% sleep duration compared to diazepam treatment). Many of the test cannabinoid compositions were even more effective than diazepam in prolonging pentobarbital-induced sleep—compositions 2 2 0.5, 1.5 2 1.5, 1.5 2 1, 1 2 1.5, 2 2 1, and 1.5 2 1.5 each exhibited a mean total sleep duration that was longer than diazepam-treated positive controls (between 134% and 252% of diazepam treatment).

(57) FIG. 7 shows a floating bar graph and data table of the percentage of mice in each treatment that fell asleep after pentobarbital administration (i.e., response rate to the treatment). As shown in FIG. 7, 82% of the test animals fell asleep in the vehicle group after pentobarbital treatment. Diazepam treatment enhanced the sleep-inducing effect of pentobarbital, such that 86% of diazepam-treated mice fell asleep after pentobarbital administration. Many of the test cannabinoid compositions were even more effective than diazepam in enhancing the sleep-inducing property of pentobarbital. Compositions 1 1.5 0.5, 1.5 2 1.5, 1.5 2 1, 1 2 1.5, and 221, each had 100% of mice in the treatment group fell asleep.

Example 3: Effects of Terpene-Containing Compositions on Sleep

(58) A mixture of terpenes resembling the profile occurring in Cannabis strain “Grand Daddy Purple” was obtained. The profile of the terpenes was as listed in table 7.

(59) TABLE-US-00007 TABLE 7 Terpene Percent Milligrams per gram β- Caryophyllene 9 90 D-Limonene 7.6 76 α- Humulene 3.5 35 Linalool 5.1 51 β-Myrcene 24 240 α-Pinene 50 500 Total Measured: 99 992

(60) Composition 1 2 2 as in Example 1 was prepared, and was also prepared with the modification of addition of 0.1% v/v terpenes.

(61) In addition, compositions with only terpenes at 0.001%, 0.01%, 0.1% and 1% v/v were prepared in the same aforementioned vehicle as cannabinoid-containing combinations (Ethanol:Cremophore:Saline).

(62) FIG. 8 shows a bar graph, line graph and a data table of the mean total sleep duration for each tested composition, as a percentage of the mean total sleep duration of subjects treated with diazepam. The 1 2 2 composition showed improvement in total sleep duration relative to diazepam. When 0.1% v/v terpenes were added to the 1 2 2 composition, there was a slight decrease in total sleep duration. Terpenes alone, without CBD, THC and CBN, did not improve total sleep duration relative to diazepam.

(67) As seen in the tables, CBN does not exist in significant, detectable levels in cannabis plant matter or vapor. In cannabis smoke, some of the THC is converted into CBN. This indicates that compositions used in examples 1 and 2, having significant amounts of CBN relative to CBD, as described, do not occur in nature.

Example 5: Treatment of Humans Using THC, CBD and CBN Compositions

(68) In treatment of humans, compositions may be administered via a variety of routes, with preference to the pulmonary, nasal, per os, and delivery via oral cavity. Compositions may be administered on a daily basis, or may be administered as per a patient's need. Compositions may be administered when sleep is desired. Optionally, compositions may be administered within 1 hour of desired bedtime.
