Lumateperone (INN; developmental code names ITI-007, ITI-722) is an investigational atypical antipsychotic which is currently under development by Intra-Cellular Therapies, licensed from Bristol-Myers Squibb, for the treatment of schizophrenia. It is also being developed by Intra-Cellular Therapies for the treatment of bipolar disorder, depression, and sleep and behavioral disturbance in dementia, autism, and other neuropsychiatric disorders. As of September 2015, lumateperone has passed the first of two phase IIIclinical trials for schizophrenia. In November 2017 the US FDA awarded Intra-Cellular Therapies Fast Track designation for lumateperone.
Relative to presently-available antipsychotics, lumateperone possesses a unique and novel mechanism of action. It acts as a 5-HT2A receptor antagonist (Ki = 0.54 nM), a partial agonist of presynaptic D2 receptors and an antagonist of postsynaptic D2 receptors (Ki = 32 nM), and a serotonin transporter blocker (Ki = 61 nM). It also possesses affinity for the D1 receptor (Ki = 52 nM) and lower affinity for the α1A– and α1B-adrenergic receptors (Ki = 73 nM at α1), 5-HT2C receptor (Ki = 173 nM), and D4 receptor. Lumateperone does not significantly bind to the 5-HT2B, H1 (Ki > 1,000 nM), muscarinic acetylcholine receptors, or many other sites (Ki > 100 nM).
Lumateperone shows a 60-fold difference in its affinities for the 5-HT2A and D2 receptors, which is far greater than that of most or all existing atypical antipsychotics, such as risperidone (12-fold), olanzapine (12.4-fold), and aripiprazole (0.18-fold). It is thought that this property may improve the effectiveness and reduce the side effect profile of lumateperone relative to currently-available antipsychotics, a hypothesis which is supported by the observation of minimal catalepsy in mice treated with the drug. Moreover, it has been expressed that this property could result in full occupancy and blockade of the 5-HT2A at low doses, with dose-dependent adjustable modulation of the D2 receptor, as well as the SERT, possible with increasing doses, which would uniquely allow for clinical optimization of efficacy and side effect incidence.
Unlike most current antipsychotics, such as haloperidol, risperidone, and olanzapine, lumateperone does not disrupt striatal dopamine signaling, a property which is likely due to its partial agonism of presynaptic D2 receptors. In accordance, similarly to aripiprazole, which is also a partial agonist of presynaptic D2 receptors, lumateperone showed no striatum-based motor side effects (i.e., catalepsy) in animals.
In phase II clinical trials, lumateperone showed statistically-significant efficacy in improvement of psychosis at a dose of 60 mg daily. In addition, it distinguished itself from its comparator risperidone in reducing negative symptoms, including improvement in social function, as well as in alleviating depressive symptoms in schizophrenia patients with comorbid depression, whereas risperidone had no effect. Lumateperone also distinguished itself from risperidone in that it produced little or no weight gain, did not negatively affect metabolic parameters (i.e., insulin, glucose, triglyceride, and cholesterol levels), did not increase prolactin levels, and did not show a rate of the side effect of akathisia that differed from placebo. In addition, lumateperone did not produce any changes in cardiovascular function, such as QTc prolongation, and unlike risperidone, it did not produce a measurable increase heart rate. Due to its favorable influence on metabolic parameters, it was concluded that lumateperone, unlike many other available antipsychotics such as risperidone, may not cause an increase in the risk of diabetes or cardiovascular disease, and hence may prove to be a significant improvement relative to many existing antipsychotic drugs in terms of long-term safety and tolerability.
Lumateperone, at a dose of 60 mg per day, was not found to be associated with any statistically significant treatment-emergent side effects relative to placebo. At a dose of 120 mg daily, the most frequent adverse effect observed was sedation/somnolence, reported by 32.5% of patients. There was no evidence of extrapyramidal symptoms or increase in suicidal ideation or behavior.

 ITI-007 is a potent 5-HT2A receptor ligand (Ki=0.5 nM) with strong affinity for dopamine (DA) D2 receptors (Ki=32 nM) and the serotonin transporter (SERT) (Ki=62 nM) but negligible binding to receptors (e.g., HI histaminergic, 5-HT2C, and muscarinic) associated with cognitive and metabolic side effects of antipsychotic drugs. ΠΊ-007 is currently in clinical trials, i.a., for treatment of schizophrenia. While ITI-007 is a promising drug, its production and formulation present challenges. In free base form, ITI-007 is an oily, sticky solid, with poor solubility, not only in water but also in many organic solvents. Making salts of the compound has proven to be unusually difficult. A hydrochloride salt form of ITI-007 was disclosed in US 7183282, but this salt is hygroscopic and shows poor stability. A toluenesulfonic acid addition salt (tosylate) of ITI- 007 was finally identified and described in WO 2009/114181.
 There is a need for alternative stable, pharmaceutically acceptable solid forms of ITI-007, which can be readily incorporated into galenic formulations.

 Thermogravimetric analysis (TGA) with infrared spectroscopy (TGA-IR):
In TGA-IR, the off-gassing materials are directed through a transfer line to a gas cell, where the infrared light interacts with the gases. The temperature ramp and first derivative weight loss information from the TGA is shown as a Gram-Schmidt (GS) profile; the GS profile essentially shows the total change in the IR signal relative to the initial state. In most cases, the GS and the derivative weight loss will be similar in shape, although the intensity of the two can differ. For this experiment are two devices coupled to each other. The TGA studies are performed using a Mettler Toledo TGA/DSCl STARe System with a 34-position auto sampler, equipment #1547. The samples are made using Al crucibles (100 μΐ; pierced).

Example 1: Co-crystal screen
 Solubility of free base in various solvents is evaluated, and based on the results of the solubility range, suitable solvents are selected for the co-crystal screen. Co-crystal formation is based on hydrogen bonding and stacking of the molecules, meaning the co-former selection is based on active groups. Grinding is a method to form co-crystals, however the free base itself is an oil/ sticky solid and therefore not suitable for this method. The free base and counter ion are added to a solution in a certain ratio to give the chance to form a co-crystal, similar to salt formation. We found the best method is to add a saturated solution of the co-former to that of the free base to find an optimal ratio for co-crystal formation.
 Three different experiments are performed with each of 26 candidate co-formers, which include sugar alcohols, amino acids, and other compounds identified as having potential to for co- crystals; adding solutions stepwise, slurry experiments and cooling crystallization experiments. The free base and co-former are dissolved prior to adding to each other. Co-formers are added in a 1 : 1 , 2: 1 and 1 :2 ratio to the free base. All experiments are performed using four different solvents, methanol, acetonitrile, ethyl acetate and toluene. All solids are characterized by XRPD. Two different ITI-007 free base co-crystals formed, with nicotinamide and with isonicotinamide. Both co-crystals were obtained by slurry experiments in methanol.
Example 2: Isonicotinamide co-crystal
 Isonicotinamide forms a possible co-crystal with ITI-007 free base by slurrying the mixture in methanol and ethyl acetate, appearing as a red/brown and yellow solid respectively. TGA-DSC analysis of the experiment using isonicotinamide in methanol results in two endothermic events,
Both endothermic events do not correspond to the free base or the co-former, which means ITI-007 free base-isonicotinamide co-crystal is formed. HPLC and Ή-ΝΜΡ analyses confirm both of the free base and the co-former to be present. Using isonicotinamide in ethyl acetate, however, does not result in a co-crystal and, no endothermic event is present in the TGA/DSC analysis.
 The slurry experiment in methanol is repeated at a gram scale. First, ITI-007 free base and isonicotinamide are each dissolved in methanol. Subsequently, the obtained solutions are mixed in a 1: 1 ratio and the resulting mixture is stirred at room temperature for 2 hours. The mixture remains a clear solution, which is evaporated under vacuum to give a brown sticky solid. XRPD analysis shows the brown sticky solid to be crystalline, as shown in Figure 1, ITI-007 free base-isonicotinamide co-crystal has formed. The corresponding peak list is showing in Table 1. The XRPD shows clustered peaks which is likely due to preferred orientation.
The present application relates to solid state forms of Lumateperone p-Tosylate and processes for preparation thereof.
The drug compound is having the adopted name “Lumateperone” and it has chemical name: l-(4-fluorophenyl)-4-[(6bR,10aS)-2,3,6b,9,10,10a-hexahydro-3-methyl-lH-pyrido[3′,4′:4,5]pyrrolo[l,2,3-de]quinoxalin-8(7H)-yl] 1-Butanone; and a structure depicted by Formula I.

Crystalline solids normally require a significant amount of energy for dissolution due to their highly organized, lattice like structures. For example, the energy required for a drug molecule to escape from a crystal is more than from an amorphous or a non-crystalline form. It is known that the amorphous forms in a number of drugs exhibit different dissolution characteristics and in some cases different bioavailability patterns compared to the crystalline form. For some therapeutic indications, one bioavailability pattern may be favored over another. Therefore, it is desirable to have amorphous forms of drugs with high purity to meet the needs of regulatory agencies and also highly reproducible processes for their preparation.
In view of the above, it is therefore, desirable to stable amorphous form of Lumateperone j?-tosylate. The amorphous form provided herein is at least stable under ordinary stability conditions with respect to purity, storage and is free flowing powder.
Amorphous solid dispersions of drugs are generally known to improve the stability and solubility of drug products. However, some of such amorphous solid dispersions are found to be unstable over time. Amorphous solid dispersions of drugs tend to convert to crystalline forms over time, which can lead to improper dosing due to differences of the solubility of crystalline drug material compared to amorphous drug material. The present invention, however provides stable amorphous solid dispersions of Lumateperone j?-tosylate with improved solubility. Moreover, the present invention provides solid dispersions of Lumateperone j?-tosylate which may be reproduced easily and is amenable for processing into a dosage form
EXAMPLE 1 : PREPARATION OF AMORPHOUS LUMATEPERONE p-TOSYLATE
Lumateperone j?-tosylate (500 mg) was dissolved in methanol (25 mL) at room temperature for clear solution and filtered to remove undissolved particles. The resultant filtrate was subjected to fast solvent evaporation using rotavapor at about 55°C to afford the solid compound. The said solid was dried under vacuum at about 45°C to afford the amorphous Lumateperone p-tosylate according to Figure 1.
