Then amorphous ASDs were obtained by evaporating the solvents in an oven at 80℃. About 10 mg of Sonrotoclax was dissolved in 1 mL of MeOH / dichloromethane (DCM) (1: 1, v / v) to prepare a stock solution and pure Sonrotoclax was obtained by evaporating the solvent in an oven at 80℃. To investigate the difference in dissolution behavior between different ASDs, the ASDs (and pure Sonrotoclax as a control) were suspended in 3 mL of FaSSIF (commercially available from Biorelevant) to a target concentration of 2 mg / mL (calculated based on Sonrotoclax) and stirred at 600 rpm under 37℃. At each time point, 300 μL of the suspension was sampled and centrifuged at 14,000 rpm for 5 mins. The concentration of Sonrotoclax was determined by HPLC after dilution by ten folds with a diluent of MeOH: Water (4: 1, v / v) .Table 3.

Manufacture process for Sonrotoclax SDP is shown in Figure 4.Manufacture process of Sonrotoclax Film-Coated Tablets, 1 mg, and 5 mg is shown in Figure 5. Manufacture process of Sonrotoclax Film-Coated Tablets, 20 mg, and 80 mg is shown in Figure 6.The YC-LSM-800 bin blender was used to mix the Sonrotoclax SDP, MCC112, anhydrous dibasic calcium phosphate, and croscarmellose sodium, talc (only for 20mg and 80mg) , then a coniwitt-200 comil was used to delump the mixture. After that, pass the magnesium stearate through a 30-mesh sieve by hand and charge them to mixture above, and then mix them using the YC-LSM-800 bin blender again.The Alexanderwerk WP120 roller compactor was used to slug the pre-blend to obtain ribbon, which was then milled to pass the 0.8mm (1mg and 5mg) , or 1.0mm (20mg and 80mg) screen to obtain intra-granule.The YC-LSM-800 bin blender was used to mix the intra-granule with MCC200, colloidal silicon dioxide (only for 20mg and 80mg) , croscarmellose sodium first. Then pass the magnesium stearate through a 30-mesh screen by hand and charge them to mixture above, followed by mixing again using the YC-LSM-800 bin blender, to obtain final blend. After the step of Blending IV in Figure 5 and Figure 6, the Blend Uniformity was confirmed.The tablet press (Manesty TPR200) was used to perform tablet compression. The dwell time is ~29ms. During tableting, the appearance, weight, hardness, and friability were monitored.YC-SC-125F coater was used to coating Opadry II suspension onto the core tablets, with target weight gain 3.0%. During coating, the appearance, and weight gain were monitored.Dry granulation tablet formulations 1 mg and 5 mg shown below in Table 6 were prepared as described above.Dry granulation tablet formulations 20 mg and 80 mg shown below in Table 7 were prepared as described above.Example 6. Effects of Disintegrants on the Dissolution of Tablet FormulationsThe formulation 80 mg was scaled up to confirm the optimal disintegrant ratio. The manufacture process was as follows: weighed SDP and other materials and put it into PE bag, blended by hand, dry granulation by the roller compactor (Alexanderwerk WP120) , added the extra materials, manually blended and compression by the tablet press (Beijing Longlitech ZP10A) . The dry granulation process was carried out in the production workshop, and the rest of the processes were carried out in the laboratory. The formulation screening table was shown in Table 8.Sample for dissolution analysis was prepared using the USP dissolution Apparatus 2 (paddle) . A rotation speed of 75rpm was set. 900 mL of de-aerated pH5.5 buffer solution with 0.2%SLS as the dissolution medium was used. Temperature of the dissolution fluid was 37±0.5℃. Six tablets were taken randomly, and each tablet was transferred into each vessel. About 5mL of solution was sampled at required timepoint. A 10um filter was installed at the first level, then filtrated with dual-step filter (0.45um PTFE filter or 0.22um PES filter) manually, discarded the first about 3 mL of filtrate and took the subsequent filter for analysis.The dissolution testing was analyzed using an HPLC with the following parameters:Column: Agilent Poroshell 120 EC-C18, 4.6×50mm, 4μm;Mobile phase: Mobile Phase A (10mM ammonium acetate in water, PH=6.5) : Mobile Phase B (ACN) =45: 55 (v / v)Flow rate: 0.8 ml / min;Injection volume: 10 μL;Column temperature: 30 ℃;UV detector wavelength: 284 nm.The dissolution results were shown in Table 9 and Figure 7.Table 9. Dissolution Results of Formulation StudyAs shown in Table 9, when the total content of disintegrant in the formulation remained unchanged and the proportion of internal disintegrants was increased, the dissolution rate of the tablet became faster as shown in Table 9 and Figure 7, until the ratio of internal and external disintegrants in the formulation was 3.5: 1.5. When the proportion of internal and external disintegrants in the formulation was 3.5: 1.5 or 4.0: 1.0, The dissolution rates of the tablets were comparable.Example 7.
