Abstract
Description
[Technical Field]
[0001] This invention relates to the crystalline form of (S)-7-(1-acryloylpiperidine-4-yl)-2-(4-phenoxyphenyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide. The invention also includes a method for preparing a crystalline form, and a method for utilizing the crystalline form as a Btk inhibitor. Regarding. [Background technology]
[0002] Bruton's tyrosine kinase (Btk) belongs to the Tec tyrosine kinase family (Vetrie et al., Nature 361: 226-233, 1993; Bradshaw, Cell Signal. 22: 1175- 84, 2010). Btk primarily affects most hematopoiesis, including B cells, mast cells, and macrophages. It is expressed in lineage cells (Smith et al., J. Immunol. 152: 557-565, 1994) and is also localized in bone marrow, spleen, and lymph node tissue. Btk is involved in B cell receptor (BCR) and FcR signaling. Although they play an important role in the pathway, they are involved in B cell development and differentiation (Khan, Immunol.Res. 23: 147, 2001). Btk is activated by upstream Src family kinases. It is converted. Once activated, Btk then phosphorylates PLC gamma, which affects the function and life of B cells. It has an effect on survival (Humphries et al., J. Biol.Chem. 279: 37651, 2004).
[0003] These signaling pathways must be precisely regulated. Mutations in the gene that controls B cells cause hereditary B cell-specific immunodeficiency in humans, known as X-linked agammaglobulinemia (XLA) (Conley et al., Annu. Rev.Immunol. 27: 199-227, 2009). Abnormalities in BCR-mediated signaling affect B cell activity. This can lead to impaired regulation of metabolism, potentially resulting in many autoimmune and inflammatory diseases. Preclinical studies have shown that Btk-deficient mice are resistant to the development of collagen-induced arthritis. This indicates that... Furthermore, clinical research on Rituxan, a CD20 antibody that can deplete mature B cells, has shown that B cells are involved in rheumatoid arthritis and systemic... It has been shown to play an important role in numerous inflammatory diseases, including lupus erythematosus and multiple sclerosis (Gurcan et al., Int. Immunopharmacol. 9: 10-25, 2009). Thus, Btk inhibitors are used to treat autoimmune diseases and / or inflammatory diseases. It is possible.
[0004] Furthermore, abnormal activation of Btk plays a crucial role in the development of B-cell lymphoma, suggesting that inhibiting Btk may be useful in treating hematological malignancies (Davis et al., Nature). 463:88-92, 2010). Preliminary clinical trial results showed that the Btk inhibitor PCI-32765 is effective in treating several types of B-cell lymphoma (for example, 54th American Society of Hematology (ASH) annual meeting abstract, Dec. 2012: 686 The Bruton's Tyrosine Kinas e(Btk)Inhibitor, Ibrutinib (PCI- 32765), Has Preferential Activity in the ABC SubtypeofRelapsed / Refractory De Novo Diffuse Large B-Cell Lymphoma (DLBCL): In terim Resultsofa Multicenter, Open-Label, Phase I Study). Btk plays a central role as a mediator in multiple signal transduction pathways. Therefore, Btk inhibitors have been strongly interested as anti-inflammatory agents and / or anti-cancer agents (Mohamed et al., Immunol. Rev.228: 58-73, 2009; Pan, Drug Newsperspect 21: 357-362, 2008; Rokosz et al.,ExpertOpin. Ther. Targets 12: 883-903, 2008; Uckun et al., Anti-cancer AgentsMed.Chem. 7: 624-632, 2007; Lou et al, J. Med. Chem. 55(10): 4539-4550, 2012).
[0005] International Application WO2014173289A discloses a series of condensed heterocyclic compounds as Btk inhibitors. In particular, WO2014173289A discloses (S)-7-(1-acryloylpiperidin-4-yl)-2-(4-phenoxyphenyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide (hereinafter referred to as Compound 1). [Chemical Structure] Compound 1
[0006] Compound 1 is a potent, specific and irreversible BTK kinase inhibitor. Biochemical studies Data obtained from preclinical studies using cell-based and animal models suggested that compound 1 has a significant effect in suppressing tumor growth in B-cell malignancies. EGFR, FGR, FRK, HER2, HER4, ITK, JAK3, LCK, and TEC were used as comparison targets. In this case, it was shown to be more selective than BTK inhibition by ibrutinib, so the compound Compound 1 is expected to have fewer side effects than ibrutinib in clinical practice. Furthermore, because compound 1 has weak inhibitory activity against ITK, it is less likely to cause rituximab-induced, antigen-dependent, cell-mediated cell damage. Because the degree of inhibition against ADCC is significantly less than that of ibrutinib, it may therefore be highly effective in treating B-cell malignancies when combined with rituximab or other ADCC-dependent antibodies.
[0007] In preclinical safety evaluations, single-dose and repeated-dose (up to 28 days) toxicity studies in rats and dogs demonstrated that compound 1 was safer than ibrutinib in terms of overall tolerance and severe toxicity. Furthermore, compound 1 exhibited superior bioavailability, as it did not have the accumulation problems observed with ibrutinib. These unique characteristics of compound 1 will lead to further clinical trials for evaluation. [Overview of the project] [Problems that the invention aims to solve]
[0008] However, in the preparation method for compound 27 in International Publication No. 2014173289, compound 1 was amorphous, which was further confirmed by the X-ray powder diffraction pattern in Figure 7A. As shown in Figure 7B, this amorphous compound 1 was shown to have a low glass transition temperature, highlighting the formulation problems of amorphous compounds, such as low stability and difficulty in purification. Therefore, it is necessary to develop a new form of compound 1, and it must have properties suitable for formulation, such as a high melting point and high stability. [Means for solving the problem]

[0129] For each experiment in Tables 4a - 4k, Tables 5a - 5e, and Table 6, approximately 20 mg of Compound 1 as an amorphous form was weighed into a glass vial, and then the corresponding solvent was added. If necessary, the mixture was heated to obtain a clear solution. Subsequently, the mixture was kept at room temperature without stirring for 1 - 2 days until solids formed from the clear solution became visible.

[0146] The experiments in Tables 4a-4k and 5a-5e were conducted on the same scale (i.e., the amount of starting material-amorphous compound 1 was approximately 20 mg). However, the ee values of the starting materials differed in each experiment. This appeared to have a significant effect on the amount of solid material that should be formed. In the experiments in Tables 4a-4k, amorphous compound 1 with 90% ee was used as the starting material, but only a small amount of solid material was formed. In the experiments in Tables 5a-5e, amorphous compound 1 with 97% ee was used as the starting material, but a very large amount of solid material was obtained. Also, when crystallized from the 90% ee starting material, the solid material obtained in the experiments in Tables 4a-4k had a low ee value. In one of the solid material samples from Tables 4a-4k, EA / hexane was used as the crystallization system, but the ee value was only 45%.
[0147] Further verification of the results in Table 5a through a scale-up experiment similar to that in Example 2 confirmed that the obtained solid material was in the desired crystalline form (morphology A).
[0148] As shown in Tables 4a-4k and 5a-5e above, the formation of crystalline solids can vary depending on the specific solvent, solvent ratio, etc.
[0149] The results in Table 6 further support the idea that the formation of crystalline solids depends on specific solvent ratios. [Table 6]

However, as summarized in Table 7, no crystalline form was produced.

The mixture was then stirred magnetically at a speed of 800 rpm. A clear solution was obtained at room temperature. Subsequently, a relatively poor solvent (see Table 8) was added to the solution to induce precipitation, or until the total volume of the poor solvent reached 15.0 mL. If precipitation did not occur... If the solution was not suitable, it was then evaporated at room temperature over time. The results are summarized in Table 8.

[0154] Cooling over time Approximately 20 mg of the sample (crystal form A) is placed in a 3 mL glass vial and then 1.0 mL of the corresponding solution is added at room temperature. The suspension was suspended in a solvent (see Table 9). The suspension was heated at 50°C while magnetically stirring at a speed of 800 rpm. The sample was transferred to a rally. The sample was equilibrated at 50°C for 2 hours and filtered using a 0.45 μm nylon membrane. The filtrate was then cooled slowly from 50°C to 5°C at a rate of 0.1°C / min. The resulting solid was kept isothermal at 5°C until isolation for XRPD analysis. As summarized in Table 9, no crystalline form was obtained.

Subsequently, the solution was added to a 20 mL vial containing 3 mL of the relative poor solvent. It was placed in a vial. The 20 mL vial was sealed with a cap and kept at room temperature, allowing the organic vapors to dissolve. Sufficient time was allowed for interaction with the liquid. At the end of day 11, the clear solution was transferred to evaporation at room temperature. The resulting solid was identified by XRPD. The results are summarized in Table 10.

[0175] Test 1: Kinase inhibition and selectivity method: (1) BTK kinase enzyme test The crystal form A of compound 1 is BTK quinate The inhibition of the enzyme (aa2-659, Carna Biosciences) was tested using time-resolved fluorescence resonance energy transfer (TR-FRET) methodology. The experiment was performed in a small volume black plate with 384 wells, and involved BTK kinase, 5μMATP, The reaction was carried out in a reaction mixture containing 2 μM peptide substrate and 0-10 μM of compound, which consisted of 50 mM Tris pH 7.4, 10 mM MgCl2, 2 mM MnCl2, 0.1 mM EDTA, 1 mM DTT, 0.005% Tween-20, and 20 nM The kinase was found in a buffer solution containing SEB and 0.01% BSA.

The ratio of photoluminescence was recorded using a PHERStarFS plate reader (BMGLabtech). Peptide substrate Phosphorylation of the anti-phosphotyrosine antibody binds to the biotinylated peptide substrate, but here the fluorescent donor (Eu 3+ Because the cryptotate is positioned in close proximity to the acceptor (streptavidin-XL665), the donor fluorophore (620nm) is able to reach the acceptor. High fluorescence resonance energy transfer occurs towards the ruolophore (665 nm). Inhibition of BTK kinase activity reduced the TR-FRET signal. (GraphpadPrism software) By fitting the data to the four-parameter logistic equation, the IC of compound 1 can be determined. 50 This led to the conclusion.

This is an HTRF-based test aimed at [the following]. Phosphorylated Tyr223 is required for the complete activation of BTK. Yes. The test used the BTKpY223 test kit (63IDC000, Cisbio) to analyze Ramos cells (CRL-1596). It was held at ATCC.
[0184] In short, Ramos cells were subjected to serum starvation for 2 hours in RPMI1640 containing 0.5% FBS. After starving the cells, incubate them with crystalline form A and incubate them in CO2 for 1 hour. The antibodies were detected at various concentrations within the test tube. After incubation, cells were stimulated with 1 mM pervanadate (PV) or Na3VO4 (OV) for 20 minutes. The cells were then spun down and lysed in 1× lysis buffer (4× lysis buffer provided in the kit) at room temperature for 10 minutes. During incubation, a 1× antibody mixture was prepared by diluting anti-BTK-d2 and anti-pBTK-K with detection buffer (supplied in the kit). The 1× antibody mixture was distributed in 2 μl / well portions onto an OptiPlate-384 test plate (6005620, PerkinElmer). Then, 18 μL of cell lysate was transferred to a test plate pre-added with antibody solution. After gentle mixing and a short spin, the plate was sealed and stored in the dark at room temperature for 18 hours. Fluorescence emission was measured at two different wavelengths (665 nm and 620 nm) using a compatible HTRF reader (PHERAstarFS, BMG). The potency of compound 1 was calculated based on the inhibition ratio between the signal intensities at 665 nm and 620 nm. IC was performed using GraphPad Prism software with the sigmoid dose-response function. 50 The value was calculated.

Per well of a 96-well plate. The number of cells seeded was optimized for each cell line to ensure logarithmic growth over a 6-day treatment period. Cells were treated three times with a 10-point dilution series. After 6 days of exposure to the compound, an amount of CellTiter-Glo reagent equal to the volume of cell culture medium present in each well was added. The mixture was mixed on an orbital shaker for 2 minutes to lyse the cells, followed by incubation at room temperature for 10 minutes to induce and stabilize the luminescence signal. The fermentation signal represents the amount of ATP, i.e., the amount of metabolically active cells. The luminescence signal was measured using a PHERAstar FS reader (BMGLabtech). IC for cell viability... 50 The value The results were determined using GraphPadPrism software and were averaged from three independent trials.

Table 17 Inhibition of hematomatous tumor cell proliferation by crystalline form A [Table 17]
[0189] Study 4: Pharmacokinetic studies of crystalline form A in mice method: For a longitudinal study, mice were randomly divided into seven groups, with four mice per group. Mice were treated with a single dose of crystalline form A of compound 1 and euthanized with carbon dioxide at different time points after administration (30 minutes, 1, 2, 4, 12, and 24 hours). For dose-dependent studies, mice were randomly divided into 9 groups of 4 mice each. Mice were treated with crystalline form A of compound 1 at different dose levels and euthanized with carbon dioxide 4 hours after administration. Treatment was administered orally via gastric tube feeding at a volume of 10 ml / kg body weight. Body weight was assessed immediately before administration, and the dose was adjusted accordingly.
[0190] PK sample preparation: For time-course studies, blood samples (50 μL per mouse) were collected from the posterior orbital sinus under isoflurane / oxygen anesthesia 15 minutes post-administration (this group of mice was also used at 24 hours), or by cardiac puncture after euthanasia at other time points. For dose-dependent studies, blood samples were collected from the posterior orbital sinus under isoflurane / oxygen anesthesia 30 minutes post-administration. Plasma was collected by centrifugation at 3,000 g for 10 minutes and stored frozen at -80°C until analysis.
[0191] PK analysis: The maximum plasma concentration (Cmax) and the time to reach Cmax (Tmax) are determined by the plasma concentration. This was obtained directly from the time-versus-time profile.
[0192] result: Crystalline form A was rapidly absorbed and eliminated in ICR mice.
[0193] Study 5: Efficacy study of crystal form A in a TMD-8 xenograft model Tumor transplantation methods: Animals were treated with cyclophosphamide (150 mg / kg in physiological saline, prepared for intraperitoneal use) and disulfide. Rufiram (prepared in physiological saline containing 0.8% Tween80, administered orally at a dose of 125 mg / kg, cyclo Pre-treatment was performed on each of the two days, one hour after each administration of phosphamide. Then, 24 hours after the second administration of cyclophosphamide, TMD-8 cells were inoculated into the animals. On the day of transplantation, the cells were... The culture medium was replaced with fresh medium. After 4 hours, the medium was removed and the cells were collected as described above. The cells were resuspended in cold PBS (4°C) and the same amount of Matrigel (BD, catalog number 356237) was added. ) is added to bring the final concentration to 2.5 × 10 7 The cells were adjusted to a concentration of cells / ml. The resuspended cells were placed on ice before inoculation. The right axillary region of each mouse was washed with 75% ethanol before cell inoculation. Each animal was inoculated with 5 × 10⁶ cells into the right anterior flank via a 26-gauge needle. 6 A 200 μl cell suspension containing cells was administered by subcutaneous injection.
[0194] The in vivo efficacy test will begin on the third day after cell inoculation, and for this purpose, first, The mice were randomly assigned to a desired number of groups, each containing 10 mice. The mice were fed twice daily (BID) on a vehicle (0.5% carboxymethylcellulose (CMC) + 0.2% Tween 80). The patients were treated with crystalline form A of compound 1 at different dose levels for 39 days. Treatment was administered orally via gastric tube feeding at a volume of 10 ml / kg body weight. Body weight was measured immediately before administration. The dosage was adjusted accordingly. Tumor volume was measured two-dimensionally twice a week using calipers (in this study, measurement was possible from day 11 after vaccination). Formula: V = 0.5 × (a × b 2 Tumor volume was calculated using the formula ), where a and b are the long and short diameters of the tumor, respectively. Statistical analysis was performed using the Student's t-test. P < 0.05 was considered statistically significant. One individual was responsible for tumor measurements throughout the entire study period. Body weight was also recorded twice a week. Mice were also monitored daily for clinical signs of toxicity during the study period.
[0195] result: The in vivo efficacy of crystalline form A was demonstrated by TMD-8DLBCL heterologous cells grown subcutaneously in NOD / SCID mice. The study was conducted using grafts. Oral administration was performed twice daily (BID) at different dose levels. Compound 1 was tolerable, and crystalline form A showed dose-dependent antitumor effects. Crystalline form A of compound 1 already exhibited strong antitumor activity in the lowest dose test. No significant effects on animal body weight were observed throughout the study in any of the treatment groups.
[0196] Study 6: Efficacy study of crystal form A in a whole-body REC-1 xenograft model Tumor transplantation methods: The animals were treated with cyclophosphamide (prepared in saline at 150 mpk ip) and disulfiram (0.8 Prepared with saline containing % TW-80, 125 mpkp.o., 1 hour after each administration of cyclophosphamide. The cells were pre-treated for two days each day. Subsequently, REC-1 cells were inoculated into the animals 24 hours after the second dose of cyclophosphamide. On the day of transplantation, the cell culture medium was replaced with fresh medium. After 4 hours, the culture medium was removed and the cells were collected as described above. The cells were then re-inserted into cold (4°C) PBS. Suspend, 1 × 10 8 The final concentration was determined to be cells / ml. The resuspended cells were placed on ice before transplantation. For animals, 1 x 10 7A 100 μl cell suspension containing cells was administered intravenously via the tail vein.
[0197] The in vivo efficacy test will begin on day 8 after cell inoculation, and for this purpose, one group of animals will be used. The mice were randomly assigned to any desired number of groups, each containing 10 mice. The mice were fed twice daily (BID) with a vehicle (0.5% carboxymethylcellulose (CMC) + 0.2% Tween80) and different diets. Treatment was administered with crystalline form A of compound 1 at a dose level for 71 days. All administration was discontinued on day 78 after inoculation. Treatment was performed by oral gastric tube feeding (oral) at a volume of 10 ml / kg body weight. The patient's weight was assessed immediately before administration, and the dosage was adjusted accordingly. The patient's weight was recorded twice a week. (From day 33 onwards, this was changed to three times a week). Clinical signs of disease in the mice were also observed daily during the study period. This study was terminated after the overall survival period had elapsed. In cases where severe toxic effects such as loss of movement were observed, the mice were euthanized and recorded as deceased.
[0198] For data analysis: Survival analysis was performed using the Kaplan-Meier method. Survival time was defined as the time from the date of tumor cell inoculation to the date of death or euthanasia of the animals. For each group, median survival time (MST), survival range with a 95% confidence interval (RST), and life extension (ILS) were calculated. Median survival time was defined as the point at which 50% of the mice died. ILS was calculated using the following formula: %ILS=(MST-MST(vehicle)) / MST(vehicle)×100 Statistical analysis was performed between each group using the Gehan-Breslow-Wilcoxon test. A p-value of < 0.05 was considered statistically significant.
[0199] result: Crystalline form A of compound 1 is used in NOD / SCID mice to treat systemic REC-1 MCL grafts. It showed dependent antitumor activity. The efficacy of crystalline form A of compound 1 was significant in this xenograft model.
[0200] Test 7: Toxicity of Crystal Form A A comprehensive nonclinical toxicity testing program, including 28-day GLP trials and studies in rats and dogs. Several studies were conducted to evaluate the preclinical safety of crystalline form A of compound 1 at different doses. These studies followed regulatory guidelines available for the preclinical development of anticancer drugs. These studies demonstrated a favorable toxicological and safety-pharmacological profile for compound 1. No deaths related to the study occurred at any dose level throughout the trials. No toxicologically significant changes or coagulations were observed throughout the trials in clinical chemistry. None of these changes were observed after the recovery phase.
[0201] Test 8: Pharmacokinetics of crystalline form A The well-validated LC-MS / MS method was frequently used in pharmacokinetic (PK) studies of crystalline form A of compound 1 after single and multiple administrations in Sprague-Dawley rats and beagle dogs.
[0202] Crystalline form A of compound 1 exhibits good oral bioavailability in rats. It was rapidly absorbed and had high plasma clearance (CL) in rats. The pharmacokinetics were linear over the dose range in female rats. Linearity was less favorable in male rats. Accumulation of compound 1 after multiple oral administrations was not statistically significant in both male and female rats. Crystalline form A of compound 1 showed moderate clearance (CL), moderately good bioavailability (F%), linear PK over the dose range, and no accumulation of compound 1 after multiple oral administrations in dogs.
[0203] Test 9: ADME of crystal form A Compound 1 was widely distributed in various tissues, but less so in brain tissue, indicating that this drug does not easily cross the blood-brain barrier.
[0204] The seven major drug-metabolizing CYP isozymes (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2D6, IC of crystalline form A of compound 1 (and CYP3A) 50 The value is found in human liver microsomes. We determined the compound and further evaluated its time-dependent inhibitory ability against major CYP isozymes. . CYP2C8(IC 50 =4.03μM), CYP2C9(IC 50 =5.69μM) and CYP2C19(IC) 50 = 7.58 μ Weak inhibition was observed against M), but inhibition against other CYP isozymes was even lower. Compound 1 does not appear to be a time-dependent CYP inhibitor against these seven major human CYPs. CYP3A is a major CYP isoform involved in metabolism in human liver microsomes.
[0205] Example 12: Clinical trial study (1) Results of compound 1 in ongoing Phase I clinical trial in patients with advanced B-cell malignancy The initial multicenter, open-label Phase I trial of Compound 1 is being conducted in Australia and New Zealand and consists of two phases—a dose escalation phase and a dose expansion phase involving 25 patients each, with a total of 100 patients to be enrolled. Of the 39 patients enrolled, the initial This includes all 25 patients from the dose escalation phase and 14 patients from the ongoing dose expansion phase. Based on the pharmacokinetics, pharmacodynamics, safety, and efficacy of compound 1 in the dose escalation phase, 320 mg once daily (QD) and 160 mg twice daily (BID) were selected in the ongoing dose expansion study. Further investigation is underway.
[0206] The deadline for data analysis was October 19, 2015. 29 objective responses were observed, including 3 complete responses (CR), 1 very good partial response (VGPR), and 25 partial responses (PR). Histological responses are summarized in Table 18. Of the 39 patients, 31 are continuing the study treatment, and this includes all patients who have responded to date.
[0207] Table 18 Histological response in patients [Table 18] 1 This includes five patients recently diagnosed with lymphocytosis; 2 One patient who had VGPR Including persons Note: CR = Complete response; PR = Partial response; SD = Stable disease; PD = Progressive disease; ORR = Response rate
[0208] Eight patients discontinued compound 1; six due to disease progression and two due to adverse events related to the original malignant tumor. Three patients died during the study as a result of disease progression or complications of disease progression. There were no serious drug-related adverse events (SAEs). Regardless of their relationship to treatment, the majority of adverse events were grade 1 or 2 in severity and did not limit treatment. Of the 19 grade 3 or higher AEs, four were assessed by researchers as potentially drug-related—all were spontaneously resolved neutropenia and did not require discontinuation of treatment. There was one case of major bleeding, a grade 3 or higher bleeding event or an intracranial hemorrhage event of any grade: identified as GI bleeding in a patient with mantle cell lymphoma with lymphomatous infiltration of the GI duct; however, this bleeding event occurred during drughold and resolved rapidly with resumption of treatment with compound 1, and therefore was not drug-related. It was not determined that they were experiencing any adverse events. Six patients had a baseline history of atrial fibrillation / flutter (AF), but no worsening of AF or new events were reported.
[0209] (2) Results of ongoing Phase I clinical trials of compound 1 in patients with Waldenström's macroglobulinemia (WM) A multicenter, open-label Phase I trial of compound 1 in B-cell malignancies was conducted in Australia, New Zealand, South Korea, and the United States, with dose escalation phases set within disease-specific cohorts, including treatment-naïve and relapsed / refractory Waldenström macroglobulinemia (R / R WM). The dose escalation phase in the trail was also included. In the initial phase, the total daily dose was tested in the range of 40 mg to 320 mg, while in the ongoing dose expansion phase... The study doses being tested are 160 mg twice daily (BID) or 320 mg once daily (QD). (2017) As of March 31st of that year, 48 WM patients were enrolled in this study. The response was based on the revised WM criteria. The decision was made in accordance with the criteria of the 6th International Workshop on Modern Warfare (IWWM).
[0210] Compound 1 has not been discontinued due to toxicity associated with Compound 1, and has been shown to date to be well-tolerated. Adverse events (AEs) were generally not severe and resolved spontaneously. The most frequently observed AE among the various attributes of the 48 patients whose safety was evaluated. (>10%) included petechiae / purpura / bruising (35%), upper respiratory tract infection (31%), constipation (25%), diarrhea (19%), epistaxis (19%), nausea (17%), cough (15%), anemia (15%), headache (15%), neutropenia (13%), and rash (13%), all of which were grade 1 or 2 in severity, with the exception of grade 3 or 4 anemia and neutropenia (8% each) and grade 3 or 4 diarrhea and headache (2% each). Five serious adverse events were thought to be associated with compound 1; these included cases of hemothorax, atrial fibrillation, colitis, febrile neutropenia, and headache. Among the AEs of particular interest were a total of three cases of atrial fibrillation (all grade 1). There were cases of grade 1 or 2, and one case of severe bleeding (hemothorax) defined as grade 3 or higher bleeding or central nervous system bleeding of any grade. Treatment was discontinued in three cases: bronchiectasis, prostate adenocarcinoma, and pyloric adenocarcinoma, one case each.
[0211] At the data cutoff, response was evaluable for 42 patients. Among patients for whom the effect could not be evaluated were two patients with a follow-up period of less than 12 weeks, three patients with baseline IgM less than 500 mg / dl, and one patient whose baseline IgM was inaccurate due to being a frozen protein. With a median follow-up period of 12.3 months (4.4–30.5 months), the ORR was 90% of patients (38 / 42 patients), the primary response rate was 76% (32 / 42 patients), but the VGPR was 43% (18 / 42 patients) and the partial response rate was 33% (14 / 42).
[0212] (3) Compound 1 in patients with chronic lymphocytic leukemia and small lymphocytic lymphoma (CLL / SLL) Results of the ongoing Phase I clinical trial A multicenter, open-label Phase I trial of compound 1 in patients with B-cell malignancies was conducted in Australia, New Zealand, South Korea, and the United States, with dose escalation and dose expansion phases in disease-specific cohorts, including treatment-naïve (TN) and relapsed / refractory (R / R) CLL / SLL. In the trail dose escalation portion, the total daily dose was tested in the range of 40 mg to 320 mg. During the ongoing dose escalation phase, the test dose is 160 mg twice daily (BID) or 320 mg once daily (QD). As of March 31, 2017, 69 CLL or SLL patients (18TN, 51R / R) have participated in the trial. It is recorded.
[0213] Compound 1 was well-tolerated in CLL / SLL. The most common adverse events (AEs) (≥10%) among all attributes were petechiae / purpura / bruising (46%), fatigue (29%), upper respiratory tract infection (28%), cough (23%), diarrhea (22%), headache (19%), and hematuria (15%). The most common adverse events were nausea (13%), rash (13%), arthralgia (12%), muscle spasms (12%), and urinary tract infection (12%). However, with the exception of one case of grade 3 purpura (subcutaneous hemorrhage), which was the only major bleeding event, all of these events were grade 1 or 2. Other adverse events of interest included one case each of grade 2 diarrhea and grade 2 atrial fibrillation. A total of 18 serious adverse events (SAEs) occurred in 13 patients, but no SAEs occurred in more than one patient. Only one patient discontinued treatment due to an AE, a grade 2 pleural effusion. Ta.
[0214] At the data cutoff, 66 patients (16 TN and 50 R / R) were followed up for 12 weeks or more. The effectiveness was evaluable, and the other three patients underwent follow-up for less than 12 weeks. After a median follow-up period of 10.5 months (2.2–26.8 months), the overall objective response rate (ORR) among patients was 94% (62 / 66), with complete response (CR) at 3% (2 / 66) and partial response (PR) at 82% (54 / 66). Furthermore, the PRs (PR-Ls) for lymphocytosis were 9% (6 / 66). 5% had stable disease (SD). Observed in (3 / 66) patients. Patients with pleural effusion discontinued treatment before 12 weeks, so response could not be evaluated. One case of Hodgkin's transformation was observed. In TN CLL / SLL, the median follow-up period was 7.6 months (3.7–11.6 months), and the ORR was 100% among patients. (16 / 16) CR was 6% (1 / 16), PR was 81% (13 / 16), and PR-L was 13% (2 / 16). R / R In CLL / SLL, with a median follow-up period of 14.0 months (2.2–26.8 months), the overall response rate (ORR) was 92% (46 / 50), complete response (CR) was 2% (1 / 50), partial response (PR) was 82% (41 / 50), and partial response-L (PR-L) was 8% (4 / 50). Stable disease was observed in 6% (3 / 50) of patients.
