(6) Methanesulfonic acid (99% w/w purity) (0.65 ml) was dissolved in water for irrigation (80 ml). 1-(4-{[4-(Dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea (220 mg) was added to the solution and stirred until a particle-free solution was achieved. Water for irrigation was added with stirring to achieve a target volume of 100 ml.

(7) (i) Visual Analysis

(8) A sample of the formulation was analysed in accordance with the visual method defined in European Pharmacopoeia Method 2.9.20 (using a Verivide (trade mark) light cabinet and a light meter reading of 3250 lux against a matt black panel and a white panel) to determine if crystallites or particles were present. The sample was tested by this method both when the solution was first made up and then 24 hours thereafter.

(9) (ii) OPM Analysis

(10) A sample of the formulation was placed on a clean glass microscopy slide and covered with a glass cover slip. It was then analysed by OPM using both non-polarised and cross-polarised light under a Nikon LV 100POL (trade mark) microscope with a 10× magnification lens and a 10× magnification eyepiece to determine if crystallites or particles were present. The image was recorded using a DFK 23UP031 TIS USB 3.0 CMOS (trade mark) Colour Industrial Camera 5 MP 1/2,5″ and image capture software. The procedure was also repeated using a sample of the formulation in a glass capillary tube. The sample was tested by this method when the solution was first made up, and then at 4 and 24 hours thereafter.

(17) A vial of lyophilised solid composition prepared in Example 3(b) was reconstituted as follows.

(18) Water for irrigation (3 ml) was injected using a syringe into the vial containing the lyophilised composition prepared in Example 3(b). The mixture was swirled until a particle-free solution was obtained.

(19) The reconstituted formulation was analysed in accordance with the methods of Example 1.

(20) FIG. 2 shows OPM micrographs taken immediately after reconstitution at 100× magnification. There was no evidence of any particulate or crystalline material within the sample.

(41) (a) Methanesulfonic acid (99% w/w purity) (0.336 ml) (35 mM) was dissolved in water for irrigation (80 ml). 2-Hydroxypropyl-beta-cyclodextrin (21.57 g, 14.72 mM) was dissolved in this buffer solution by stirring to achieve total dissolution. 1-(4-{[4-(Dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea (200 mg, 0.325 mM) was added to the solution and stirred until a particle-free solution was achieved. Water for irrigation was added with stirring to achieve a target volume of 100 ml.
(b) The formulation from (a) was filled into 10 mL vials to a target volume of 3 ml. The vials were partially stoppered (not sealed) with a 20 mm Gray Lyo D777-1 V10-F597W FluroTec Siliconised (trade mark) stopper. The vials were loaded into stainless steel trays and inserted into a LSL1000 (trade mark) freeze dryer. The shelf temperature was set at 25° C. The freeze drying cycle was run using the tabulated method below.

(43) The freeze dryer was back-filled with sterile filtered nitrogen to a set point of 500 Torr (ca. 666 mbar or 66,600 Pascals), and the vials were fully closed using the stoppers.

(44) Each vial contained the freeze dried (lyophilised) formulation as an off-white solid.

ANALYSIS OF EXAMPLES 1-18

(45) The Examples shown in the following Table were analysed by the visual method defined in European Pharmacopoeia Method 2.9.20 and the OPM method both as described in Example 1. The results are tabulated below.

(46) Further, the formulations of Examples 1, 2 and 6-18 were each lyophilised by the same method used in Examples 3(b) and 4(b) and then each reconstituted by the same method as used in Examples 5A and 5B.

(47) In this Table “particle-free” means that the the formulation was visually clear and free of visible crystallites or particulates, and “opalescent, particle-free” means that the the formulation was free of visible crystallites or particulates but had a solution opalescence that is thought to result from the formation of a chromonic liquid crystal phase. There are Examples shown where the opalescence disappears on reconstitution of the formulation following lyophilisation. All Examples studied are free of visible crystallite or particulate matter and meet the required “clear solution” definition as described earlier.

Sample A was prepared by a similar procedure to that of Example 3 except that 2000 mg of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea (i.e. 20 mg/ml), 100 mM of methanesulfonic acid (0.65 ml) and 3000 mg of mannitol were used to prepare the lyophile.

Explanatory Notes

(62) Condition the UHPLC system, prior to starting the analysis, with the mobile phases. Prior to running samples, ensure that the system is suitable for use by injecting blank diluent, sensitivity solution and standard preparation using the chromatographic conditions above.

(63) The following criteria must be satisfied on initial UHPLC set-up or after any significant change to the system. It is recommended to inject at least one conditioning blank prior to testing system suitability.

(65) Inject the check standard preparation according to the chromatographic conditions above. The response factor (calculated from the area, standard weight, dilution factor and purity factor of the standard) of this check standard preparation must be within ±2% of the standard preparation.

(66) After the system suitability has been demonstrated, inject the blank solution, standard preparation and prepared test samples, followed by an injection of the standard preparation, according to the chromatographic conditions above. It is recommended that no more than 6 test samples be injected between standard preparation injections. For each injection (standard and sample), measure the retention time and area of the 1-(4-{[4-(dimethylamino) piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea peak in each chromatogram. For each sample injection, also measure the retention times and peak area of any peaks present in the sample injection that do not appear in the blank injection. Do not integrate gradient artifacts, if present. Compare the blank injection chromatogram to the sample chromatogram to determine which peaks in the sample are related to the blank and gradient artifact peaks. Calculate the % w/w degradants and report the individual degradant peaks which are at or above 0.05% w/w. Unknown degradants should be reported individually by their relative retention time. Known degradants should be reported individually by name.

(67) The results are summarised in the Tables below.
