Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 63 / 184,941, filed May 6, 2021, and U.S. Provisional Patent Application No. 63 / 212,316, filed June 18, 2021, each of which is incorporated by reference in its entirety herein. [Background technology]

[0002] Since its identification in 1982 as one of the first human oncogenes (Der et al., 1982), KRAS (Kirsten rat sarcoma viral oncogene homolog) has been the subject of extensive academic and industrial research as a key node in the MAPK signaling pathway, as a transforming factor in a network of parallel effector pathways (e.g., PI3K / AKT) (Vojtek et al., 1998), and as a potential target for anticancer drugs (Malumbres et al., 2003). Despite progress in the development of inhibitors of upstream and downstream nodes in the MAPK pathway (e.g., EGFR (Sridhar et al., 2003), BRAF (Holderfield et al., 2014), and MEK (Caunt et al., 2015), the KRAS protein has historically proven resistant to direct inhibition.

[0003] KRAS is a G protein that couples extracellular mitogenic signaling to intracellular growth-promoting responses. KRAS acts as an intracellular "on / off" switch. Mitogen stimulation induces the binding of GTP to KRAS, resulting in a conformational change that allows KRAS to interact with downstream effector proteins, resulting in cell proliferation. Normally, growth-promoting signaling is regulated by the action of GTPase-activating proteins (GAPs), which revert KRAS to its GDP-bound, non-proliferative state. Mutations in KRAS impair the regulated cycling of KRAS between these GDP-bound and GDP-bound states, leading to the accumulation of the GDP-bound, active state and impaired cell proliferation (Simanshu et al., 2017).

[0004] Attempts to develop inhibitors of mutant KRAS proteins have historically been hampered by the absence of a druggable pocket on the protein surface (Cox et al., 2014). Subsequent discoveries in the field have led to significant new efforts in KRAS inhibitor research, culminating recently in the entry of KRAS inhibitors into human clinical trials: https: / / clinicaltrials.gov / : e.g., NCT03600883 & NCT04185883 (sotorasib, AMG510) (last accessed April 23, 2021). These efforts recently culminated in the submission of a New Drug Application for sotorasib to the United States Food and Drug Administration (Amgen Press Release, Dec. 16, 2020; https: / / wwwext.amgen.com / newsroom / press-releases / 2020 / 12 / amgen-submits-sotorasib-new-drug-application-to-us--fda-for-advanced-or-metastatic-non-small-cell-lung-cancer-with-kras-g12c-mutation, last accessed April 21, 2021).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The present disclosure is based, in part, on the discovery that formulations disclosed herein comprising sotorasib and certain excipients in certain amounts provide immediate release formulations.

[0013] Furthermore, the present disclosure is based in part on the discovery that the ratio of plastic excipients to brittle excipients in a sotorasibe formulation, e.g., in the form of a tablet, can affect the physical properties of such formulation. For example, as shown herein, sotorasibe formulations with higher amounts of plastic excipients (e.g., microcrystalline cellulose) and lower amounts of brittle excipients (e.g., lactose) have been found to have problems with disintegration that affect the performance of the formulation. In contrast, sotorasibe formulations, e.g., in the form of a tablet, with lower amounts of plastic excipients and higher amounts of brittle excipients have been found to have poor tensile strength. Thus, a suitable balance between overall brittleness and plasticity is required for a suitable formulation. As exemplified herein, sotorasibe tablet formulations are provided that include ratios of plastic excipients to brittle excipients that do not have the above-mentioned tensile strength and tablet disintegration problems.

Sotorasib is also known as AMG 510 or 6-fluoro-7-(2-fluoro-6-hydroxyphenyl)-(1M)-1-[4-methyl-2-(propan-2-yl)pyridin-3-yl]-4-[(2S)-2-methyl-4-(prop-2-enoyl)piperazin-1-yl]pyrido[2,3-d]pyrimidin-2(1H)-one, and has the following structure: [ka]

[0020] Formulation ingredients (e.g., diluents) can generally be classified by the way they deform under compression forces, either by brittle fracture or by plastic deformation. The degree of deformation for brittle materials depends on the speed and duration of the compression event (the compression applied), giving a strain rate sensitivity value for such materials of 0% (zero). The deformation of plastic materials depends on the speed and duration of the compression event, which is described by the strain rate sensitivity. When developing tablet formulations, it is desirable to use a mixture of ingredients: some with brittle characteristics to minimize strain rate sensitivity and some with moderate plastic characteristics to increase the available surface area to form bonds during compression. Excipients can be classified using the average Heckel yield pressure, determined, for example, according to Zhang et al., 2017, which is incorporated herein by reference in its entirety. Excipients with an average Heckel yield pressure greater than 125 MPa are considered brittle excipients. Excipients with an average Heckel yield pressure less than 125 MPa are considered plastic excipients. In some embodiments, the plastic excipient has an average Heckel yield pressure of less than 100 MPa. In some embodiments, the brittle excipient has an average Heckel yield pressure of more than 150 MPa. In some embodiments, the plastic excipient has an average Heckel yield pressure of 50 MPa to 125 MPa. In some embodiments, the brittle excipient has an average Heckel yield pressure of more than 125 MPa to 350 MPa.

In some embodiments, the therapeutically effective amount of sotorasib is 180 mg, 240 mg, 260 mg, 720 mg, or 960 mg.

[0046] In some embodiments, the therapeutically effective amount is 240 mg. In some embodiments, the therapeutically effective amount is provided in two dosage units (e.g., 2 x 120 mg tablets).

[0047] In some embodiments, a therapeutically effective amount is provided by a single dosage unit (eg, 1 x 240 mg tablet).

[0048] In some embodiments, the therapeutically effective amount of sotorasib is 960 mg. In some embodiments, the therapeutically effective amount is provided in eight dosage units (e.g., 8 x 120 mg tablets). In some embodiments, the therapeutically effective amount is provided in four dosage units (e.g., 4 x 240 mg tablets). In some embodiments, the therapeutically effective amount is provided in three dosage units (e.g., 3 x 320 mg tablets).

[0049] As used herein, the terms "treat", "treatment", "treating" or "amelioration" refer to therapeutic treatment, the purpose of which is to reverse, alleviate, ameliorate, inhibit, slow or stop the progression or severity of a condition associated with a disease or disorder, e.g., cancer. The term "treating" includes reducing or ameliorating at least one adverse effect or symptom of a condition, disease or disorder. A treatment is generally "effective" if one or more symptoms or clinical markers are reduced. Alternatively, a treatment is "effective" if the progression of a disease is reduced or stopped. That is, "treatment" does not only include the improvement of symptoms or markers, but also includes the cessation or at least slowing of the progression or worsening of a condition compared to that expected in the absence of treatment. Beneficial or desired clinical outcomes include, but are not limited to, amelioration of one or more symptoms, reduction in the extent of disease, stabilization of the disease state (i.e., not worsening), delay or slowing of disease progression, improvement or palliation of the disease state, remission (whether partial or total), and / or reduced mortality.

[0050] KRAS G12C cancer Without wishing to be bound by any particular theory, the following is noted: sotorasib inhibits KRAS G12CSotorasib is a small molecule that specifically and irreversibly inhibits KRAS p.G12C (Hong et al., 2020, at 1208). Hong et al. report that "[p]re-clinical studies showed that [sotorasib] inhibited nearly all detectable phosphorylation of extracellular signal-regulated kinase (ERK), a key downstream effector of KRAS, and produced durable complete tumor regression in mice bearing KRAS p.G12C tumors" (ibid.; see also Canon et al., 2019, and Lanman et al., 2020). Thus, in various embodiments, a total daily dose of 240 mg or 960 mg sotorasib is disclosed for use in treating cancers in which one or more cells express a KRAS G12C mutant protein.

[0051] Sotorasib was evaluated in a phase 1 dose escalation and expansion study in 129 subjects with locally advanced or metastatic cancer harboring histologically confirmed KRAS G12C mutations identified by local molecular testing on tumor tissue, including 59 subjects with non-small cell lung cancer, 42 subjects with colorectal cancer, and 28 subjects with other tumor types (Hong et al., 2020, at page 1208-1209). Hong et al. reported disease control rates (95% CI) of 88.1% for non-small cell lung cancer, 73.8% for colorectal cancer, and 75.0% for other tumor types (Hong et al., 2020, at page 1213, Table 3). The cancer types showing either stable disease (SD) or partial response (PR) reported by Hong et al. were non-small cell lung cancer, colorectal cancer, pancreatic cancer, appendix cancer, endometrial cancer, cancer of unknown primary site, ampullary cancer, gastric cancer, small intestine cancer, paranasal sinus cancer, cholangiocarcinoma, or melanoma (Hong et al., 2020, p. 1212 (Figure A), and appendix (p. 59 (Figure S5) and p. 63 (Figure S6)).

[0052] KRAS G12C mutations occur at the alteration frequencies shown in the table below (Cerami et al., 2012; Gao et al., 2013). For example, the table shows that 11.6% of subjects with non-small cell lung cancer have cancer in which one or more cells express the KRAS G12C mutant protein. Thus, KRAS G12C Sotorasib, which specifically and irreversibly binds to, is useful for treating subjects with cancers, including, but not limited to, those listed in the table below.

[0056] Methods for detecting KRAS, STK11, KEAP1 EGFR, ALK, and / or ROS1 mutation status The presence or absence of G12C, STK11, KEAP1, EGFR, ALK and / or ROS1 mutations in cancers as described herein can be determined using methods known in the art. Determining whether a tumor or cancer contains a mutation can be done, for example, by evaluating the nucleotide sequence encoding the protein, by evaluating the amino acid sequence of the protein, or by evaluating the characteristics of a putative mutant protein, or by any other suitable method known in the art. Wild-type human KRAS (nucleotide sequence set forth in Genbank accession no. BC010502; amino acid sequence set forth in Genbank accession no. AGC09594), STK11 (Gene ID: 6794; available at www.ncbi.nlm.nih.gov / gene / 6794; accessed January 2020), KEAP1 (Gene ID: 9817; available at www.ncbi.nlm.nih.gov / gene / 9817; accessed January 2020), EGFR (Gene ID: 1956; available at www.ncbi.nlm.nih.gov / gene / 1956; accessed March 2021), ALK (Gene ID: 238; available at www.ncbi.nlm.nih.gov / gene / 238; accessed March 2021), and ROS1 (Gene ID: 239; available at www.ncbi.nlm.nih.gov / gene / 239; accessed March 2021) were identified. The nucleotide and amino acid sequences of the polypeptide (SEQ ID NO: 6098; available at www.ncbi.nlm.nih.gov / gene / 6098; accessed March 2021) are known in the art.

[0057] Methods for detecting mutations include, but are not limited to, polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assays, polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) assays, real-time PCR assays, PCR sequencing, mutant allele-specific PCR amplification (MASA) assays, direct and / or next generation sequencing, primer extension reactions, electrophoresis, oligonucleotide ligation assays, hybridization assays, TaqMan assays, SNP genotyping assays, high-resolution melting assays, and microarray analysis. In some embodiments, samples are evaluated for mutations, such as KRAS G12C mutations, by real-time PCR. In real-time PCR, a fluorescent probe specific for a particular mutation, such as KRAS G12C mutation, is used. If a mutation is present, the probe binds and fluorescence is detected. In some embodiments, mutations are identified using a direct sequencing method of a specific region in a gene. This approach identifies all possible mutations in the sequenced region. In some embodiments, the presence or absence of an insertion mutation can be detected using gel electrophoresis, capillary electrophoresis, size exclusion chromatography, sequencing, and / or arrays. In some embodiments, methods include, but are not limited to, detection of the mutant using binding agents (e.g., antibodies) specific for the mutant protein, protein electrophoresis and Western blotting, and direct peptide sequencing.

[0058] In some embodiments, multiplex PCR-based sequencing is used for mutation detection and may include some amplicons to provide improved sensitivity of detection of one or more genetic biomarkers.For example, multiplex PCR-based sequencing may include about 60 amplicons (e.g., 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, or 70 amplicons).In some embodiments, multiplex PCR-based sequencing may include 61 amplicons. Amplicons generated using multiplex PCR-based sequencing may range from about 15 bp to about 1000 bp (e.g., about 25 bp to about 1000 bp, about 35 bp to about 1000 bp, about 50 bp to about 1000 bp, about 100 bp to about 1000 bp, about 250 bp to about 1000 bp, about 500 bp to about 1000 bp, about 750 bp to about 1000 bp, about 15 bp to about 750 bp, about 15 bp to about 500 bp, about 15 bp to about 300 bp, about 15 bp to about 200 bp, about 15 bp to about 100 bp, about 15 bp to about 80 bp, about 15 bp to about 75 bp, about 15 bp to about 50 bp, about 15 bp to about 40 bp, about 15 bp to about 30 bp, about 15 bp to about 20 bp, about 20 bp to about 100 bp, about 25 bp to about 50 bp, or about 30 bp to about 40 bp). For example, an amplicon generated using multiplex PCR-based sequencing may include a nucleic acid having a length of about 33 bp.

[0059] In some embodiments, the presence of one or more mutations present in a sample obtained from a patient is detected using a sequencing technique (e.g., a next-generation sequencing technique). Various sequencing techniques are known in the art. For example, methods for the detection and characterization of circulating tumor DNA in cell-free DNA can be described elsewhere (see, e.g., Haber and Velculescu, 2014). Non-limiting examples of such techniques include SafeSeqs (see, e.g., Kinde et al., 2011), OnTarget (see, e.g., Forshew et al., 2012), and TamSeq (see, e.g., Thompson et al., 2012).

[0060] In some embodiments, the presence of one or more mutations present in a sample obtained from a patient is detected using droplet digital PCR (ddPCR), a method known to be highly sensitive for detecting mutations. In some embodiments, the presence of one or more mutations present in a sample obtained from a patient is detected using other sequencing techniques, including, but not limited to, chain termination techniques, shotgun techniques, sequencing by synthesis methods, methods using microfluidic technology, other capture techniques, or other sequencing techniques known in the art that are useful for detecting small amounts of DNA in a sample (e.g., ctDNA in a cell-free DNA sample).

[0061] In some embodiments, the presence of one or more mutations present in the sample obtained from the patient is detected using an array-based method.For example, the step of detecting genetic alterations (e.g., one or more genetic alterations) in cell-free DNA is carried out using a DNA microarray.In some embodiments, the DNA microarray can detect one or more of a plurality of cancer cell mutations.In some embodiments, the cell-free DNA is amplified before detecting genetic alterations. Non-limiting examples of array-based methods that may be used in any of the methods described herein include complementary DNA (cDNA) microarrays (see, e.g., Kumar et al. 2012; Laere et al. 2009; Mackay et al. 2003; Alizadeh et al. 1996), oligonucleotide microarrays (see, e.g., Kim et al. 2006; Lodes et al. 2009), bacterial artificial chromosome (BAC) clone chips (see, e.g., Chung et al. 2004; Thomas et al. 2005), single nucleotide polymorphism (SNP) microarrays (see, e.g., Mao et al. 2007; Jasmine et al. 2012), microarray-based comparative genomic hybridization arrays (array-CGH) (see, e.g., Beers and Nederlof, 2006; Pinkel et al. 2005; Michels et al. 2009), and other methods. al. 2007), molecular inversion probe (MIP) assays (see, e.g., Wang et al. 2012; Lin et al. 2010). In some embodiments, the cDNA microarray includes an Affymetrix microarray (see, e.g., Irizarry 2003; Dalma-Weiszhausz et al. 2006), a NimbleGen microarray (see, e.g., Wei et al. 2008; Albert et al. 2007), an Agilent microarray (see, e.g., Hughes et al. 2001), or a BeadArray array (see, e.g., Liu et al. 2017).In some embodiments, the oligonucleotide microarray is a DNA tiling array (e.g., Mockler and Ecker, 2005; Bertone et al. 2006). Other suitable array-based methods are known in the art.

[0062] The method for determining whether a tumor or cancer contains a mutation can use a variety of samples. In some embodiments, the sample is taken from a patient with a tumor or cancer. In some embodiments, the sample is a fresh tumor / cancer sample. In some embodiments, the sample is a frozen tumor / cancer sample. In some embodiments, the sample is a formalin-fixed paraffin-embedded (FFPE) sample. In some embodiments, the sample is a circulating cell-free DNA and / or circulating tumor cell (CTC) sample. In some embodiments, the sample is processed into a cell lysate. In some embodiments, the sample is processed into DNA or RNA. In certain embodiments, the sample is obtained by resection, core needle biopsy (CNB), fine needle aspiration (FNA), urine collection, or hair follicle collection. In some embodiments, liquid cytology using whole blood or cerebrospinal fluid may be used to assess the mutation status.

[0063] In various embodiments, a test approved by a regulatory agency such as the US Food and Drug Administration (FDA) is used to determine whether a patient has a mutation, e.g., a KRASG12C mutated cancer, or whether a tumor or tissue sample obtained from such a patient contains cells with a mutation. In some embodiments, the test for KRAS mutation used is the therascreen® KRAS RGQ PCR kit (Qiagen). The therascreen® KRAS RGQ PCR kit is a real-time quantitative PCR assay for the detection of seven somatic mutations (G12A, G12D, G12R, G12C, G12S, G12V, and G13D) in codons 12 and 13 of the human KRAS oncogene using a Rotor-Gene Q MDx 5plex HRM instrument. The kit is intended for use with DNA extracted from FFPE samples of NSCLC samples obtained by resection, CNB, or FNA. Mutation testing for STK11, KEAP1, EGFR, ALK, and / or ROS1 can be performed with commercially available tests such as the Resolution Bioscience Resolution ctDx Lung™ Assay, which includes 24 genes (including those therapeutic in NSCLC). Tissue samples can be tested using the Tempus xT 648 panel.

[0064] In some embodiments, the cancer is identified as having a KRAS G12C mutation. In some embodiments, the cancer is identified as having a STK11 mutation, e.g., a loss-of-function mutation. In some embodiments, the cancer is identified as having a KEAP1 mutation, e.g., a loss-of-function mutation. In some embodiments, the cancer is identified as having wild-type STK11. In some embodiments, the cancer is identified as having wild-type KEAP1.

[0065] In various embodiments, the cancer is identified as having a loss-of-function mutation in STK11 and a wild-type KEAP1. In some embodiments, the cancer is identified as having a loss-of-function mutation in STK11 and a loss-of-function mutation in KEAP1. In some embodiments, the cancer is identified as having a wild-type STK11 and a wild-type KEAP1. In some embodiments, the cancer is identified as having a wild-type STK11 and a loss-of-function mutation in KEAP1.

[0066] The term "loss-of-function mutation" as used herein refers to a mutation (e.g., substitution, deletion, truncation, or frameshift mutation) that results in the expression of a mutant protein that no longer exhibits wild-type activity (e.g., reduced or eliminated wild-type biological or enzymatic activity), or that results in the expression of only a fragment of a protein that no longer exhibits wild-type activity, or that does not result in the expression of a wild-type protein. For example, a loss-of-function mutation affecting the STK11 gene in a cell may result in the expression of a reduced STK11 protein, the expression of only a fragment of the STK11 protein, or the expression of an STK11 protein that exhibits reduced or no enzymatic activity in a cancerous cell (e.g., no serine / threonine kinase enzymatic activity). Similarly, a loss-of-function mutation affecting the KEAP1 gene in a cell may result in the expression of a reduced KEAP1 protein, the expression of only a fragment of the KEAP1 protein, or the expression of a KEAP1 protein that exhibits reduced or no activity in a cell (e.g., unable to interact with or activate erythroid transcription factor 2-related transcription factor 2 (NRF2)).

[0067] Methods for detecting PD-L1 protein expression PD-L1 expression can be determined by methods known in the art. For example, PD-L1 expression can be detected using PD-L1 IHC 22C3 pharmDx, an FDA-approved in vitro diagnostic immunohistochemistry (IHC) test developed by Dako and Bristol-Meyers Squibb as a companion test for treatment with pembrolizumab. This is a quantitative assay that uses a monoclonal mouse anti-PD-L1, clone 22C3 PD-L1, and the EnVision FLEX visualization system on an automated stainer, Lin 48, to detect PD-L1 in FFPE samples, such as human non-small cell lung cancer tissue. Expression levels can be measured using the tumor proportion score (TPS), which measures the percentage of viable tumor cells that show partial or complete membrane staining at any intensity. Staining can range from 0% to 100% to indicate PD-L1 expression.

[0068] PD-L1 expression can also be detected using PD-L1 IHC 28-8 pharmDx, an FDA-approved in vitro diagnostic immunohistochemistry (IHC) test developed by Dako and Merck as a companion test for treatment with nivolumab. This quantitative assay uses monoclonal rabbit anti-PD-L1, clone 28-8, and the EnVision FLEX visualization system on the automated stainer Lin 48 to detect PD-L1 in formalin-fixed, paraffin-embedded (FFPE) human cancer tissues.

[0069] Other commercially available tests for the detection of PD-L1 include the Ventana SP263 assay (developed by Ventana in collaboration with AstraZeneca), which utilises a monoclonal rabbit anti-PD-L1, clone SP263, and the Ventana SP142 assay (developed by Ventana in collaboration with Genentech / Roche), which uses rabbit monoclonal anti-PD-L1 clone SP142.

[0070] In some embodiments, a test approved by a regulatory agency, such as the U.S. Food and Drug Administration (FDA), is used to determine the PD-L1 TPS of a cancer as disclosed herein. In various embodiments, the PD-L1 TPS is determined using an immunohistochemistry (IHC) test. In some embodiments, the IHC test is the PD-L1 IHC 22C3 pharmDx test. In various embodiments, the IHC test is performed using a sample obtained, for example, by resection, CNB, or FNA.

In various embodiments, patients have a PD-L1 TPS of 100%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 50%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% or less. In various embodiments, the patient has a PD-L1 TPS of 50% or less, or 1% or less. In various embodiments, the patient has a PD-L1 TPS of more than 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 50%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1%. In various embodiments, the patient has a PD-L1 TPS score in a range bounded by any of the values ​​recited in the preceding embodiments. For example, the patient has a PD-L1 TPS score in the range of less than 50% and 1% or more, less than 50% and more than 1%, less than 50% and more than 1%, less than 50% and more than 1%, or less than 50% and more than 1%.

[0074] Patients can respond to sotorasib therapy as measured by at least stable disease (SD) as determined by RECIST 1.1 protocol (Eisenhauer, et al., 2009). At least stable disease is stable disease, or has shown partial response (PR) or complete response (CR) (i.e., "at least SD" = SD + PR + CR, often referred to as disease control). In various embodiments, stable disease does not shrink enough to qualify as partial response (PR) or expand enough to qualify as progressive disease (PD). In various embodiments, patients show at least partial response (i.e., "at least PR" = PR + CR, often referred to as objective response).

[0075] Response may be measured by one or more of: reduction in tumor size, inhibition or reduction in tumor growth, reduction in target or tumor lesions, delayed progression-free time, absence of new tumors or lesions, reduction in new tumor formation, increased survival or progression-free survival (PFS), and absence of metastasis. In various embodiments, the progression of a patient's disease may be assessed by measuring tumor size, tumor lesions, or formation of new tumors or lesions, by evaluating the patient using computed tomography (CT) scans, positron emission tomography (PET) scans, magnetic resonance imaging (MRI) scans, x-rays, ultrasound, or some combination thereof.

[0076] Progression-free survival can be evaluated as described in RECIST 1.1 protocol.In various embodiments, the patient shows a PFS of at least 3 months.In some embodiments, the patient shows a PFS of at least 6 months.

[0080] Example 1 To ensure proper process and formulation performance including flow, dose uniformity, and compressibility, dry granulation via roller compaction was selected as the manufacturing process. Briefly, sotorasib was weighed and suspended in a blender for blending along with excipients including microcrystalline cellulose (MCC), lactose, and croscarmellose sodium. The preblend was passed through a suitable metal screen and then mixed in a suitable tumble blender. An appropriate amount of screened magnesium stearate was then dispensed into the preblend and thoroughly mixed in the blender at a controlled duration and speed. The lubricated blend was then either directly compressed on a tablet press, slug compressed, or compressed into ribbons using roll force and roll gap as shown in the table below. The ribbons and slugs were milled into granules in a vibratory mill equipped with a 1.0 mm screen. The resulting granules were then lubricated by adding screened magnesium stearate to the blender and thoroughly mixed at a controlled duration and speed. The final blend was compressed into tablets on a tablet press. Tablet appearance, weight, thickness and hardness were monitored at predefined intervals throughout the operation of the compression unit. The final tablets were coated using suitable coating equipment as shown in the table below.

[0098] Example 2 - Stability Study Sotorasib 120 mg (Formulation No. 7 and No. 8), Sotorasib 240 mg (Formulation No. 9b), Sotorasib 320 mg (Formulation No. 10b) and Sotorasib 30 mg (Formulation No. 6) tablets were packaged in 75 cc (with silica gel as desiccant) or 215 cc HDPE (High Density Polyethylene) bottles (without desiccant) with heat induction seal and polypropylene child resistant closure. The bottled tablets were placed under stability conditions at -20°C, 5°C, 30°C / 65% RH (relative humidity) long term storage conditions and 40°C / 75% RH accelerated conditions. Samples were evaluated for water content, assay (% of label content), total impurities and dissolution. Water content was determined by quantitative Karl Fischer titration in a titration vessel with methanol, where accurately weighed tablets were homogenized in situ using a homogenizer and titrated with standardized KF titrant. Assay (% of labelled content) was determined using a reversed phase HPLC method with UV detection. Primary analytes were separated from related impurities and potential degradants by gradient elution and quantified against external reference standards of known purity. Total impurities are reported as the sum of organic impurities whose levels were determined using the same method as the assay determination. See Tables 14-28 for results from stability studies.

[0129] The stability data showed that all test results met the acceptance criteria: comparable stability results were observed between Formulation No. 7 and Formulation No. 8. For Formulation No. 6, the stability data showed that all test results met the acceptance criteria with no significant trends observed at storage conditions of 5° C. and 25° C. / 60% RH for 12 months and at 40° C. / 75% RH for 6 months. Similarly, the stability data for Formulation No. 7 and No. 8 met the acceptance criteria after 3 months under storage conditions of 5° C., 30° C. / 65% RH, and 40° C. / 75% RH with no significant trends observed with storage conditions.

[0130] Formulation No. 8 tablets were subjected to a comprehensive accelerated stability program (ASAP) study and the level of degradation was higher with increasing temperature and humidity but was within the specification limits at the most stressful condition, 60°C / 75% RH (4 weeks). The results from the ASAP study indicated that Formulation No. 8 was stable to temperature and slightly sensitive to humidity. Additionally, at 4 weeks, ssNMR was performed on Formulation No. 8 tablets stored at 60°C / 75% RH and the results confirmed no change in shape.

[0145] Example 3 - Dissolution Test In addition to release and stability data, a comparison of dissolution profiles in multiple solvents was performed. General Chapter Dissolution, available at online.uspnf.com (last accessed April 26, 2021) <711> See, Document ID,1_GUID-AC788D41-90A2-4F36-A6E7-769954A9ED09_1_en-US (Official Date: May 1, 2016). The dissolution medium contained 50 mM sodium phosphate, pH 6.8, an appropriate amount of surfactant at 37°C, 900 mL to achieve sink conditions. The surfactant used in this example was sodium dodecyl sulfate (SDS) at 0.2-1% (w / v) for the 1 mg and 360 mg tablets (Table 35). The dissolution method was performed according to USP <711> The apparatus is used with a paddle speed of 75 rpm, see Figures 1-11.

[0146] [Table 39]

[0147] Example 4 - Water dispersion test The pharmacokinetics of sotorasib administered as 8 x 120 mg tablets (Formulation No. 8) and as tablets predispersed in water were evaluated.

[0148] Each subject received sotorasib administered as 8 x 120 mg tablets (Treatment A) and 8 x 120 mg tablets dispersed in a total volume of 240 mL (dose + dosing container rinse) or water in either Period 1 or Period 2 according to the group to which the subject was assigned. Doses were administered in the morning after an overnight fast of at least 10 hours on Days 1 and 4.

[0149] A total of 13 subjects were enrolled in the study (7 subjects receiving the sequence Treatment A followed by Treatment B, and 6 subjects receiving the sequence Treatment B followed by Treatment A). Data for all subjects were included in the pharmacokinetic (PK) and safety analyses.

[0150] Blood samples were collected for analysis of plasma concentrations of sotorasib and sotorasib metabolites. Plasma PK concentrations determined for sotorasib and sotorasib metabolite M24 were as follows: -Maximum plasma concentration (C max ), - Area under plasma concentration-time (AUC) from time 0 to the last quantifiable time (AUC last ), - AUC from time 0 to infinity (AUC inf ), -Cmax arrival time (t max ) - Apparent terminal elimination half-life (t 1 / 2 ) - apparent plasma clearance (CL / F; sotorasib only), - apparent volume of distribution during the terminal phase (Vz / F; sotorasib only), - The percentage of AUCinf by extrapolation from the last time of measurable concentration to infinity (%AUCextrap), -Disappearance rate constant (λ z ), - Correlation coefficient (R 2 ), -The difference between the start and end of the exponential fit is T 1 / 2 Divided by (span ratio), -λ z The number of data points included in the measurement (number of points), - the lower limit of the terminal phase (at the beginning of the exponential fit), and - Upper limit of the terminal phase (at the end of the exponential fit).

[0151] Statistical Methods: Statistical analysis was performed to compare sotorasib PK after tablets dispersed in water (Treatment B) versus sotorasib oral tablets (Treatment A). AUC last , AUC inf , and C maxPK parameters including AUC were estimated and compared between treatment A and treatment B. Natural log-transformed PK parameters were analyzed using mixed models. The models included treatment, period, and sequence as fixed effects, with subject nested within sequence as a random effect. Each PK parameter (AUC last , AUC inf , and C max ), least squares means (LSMs), differences in LSMs between treatment A and treatment B, and corresponding 90% confidence intervals (CIs) were calculated for each treatment separately, and these values ​​were then back transformed to obtain geometric least squares means (GLSMs), ratios of GLSMs, and corresponding 90% CIs. Additionally, pooled estimates of within-subject coefficients of variation (across all treatments) were calculated, and residual plots were generated to assess the adequacy of the fitted models.

[0152] result: Following administration of sotrasib as a tablet dispersed in water (Treatment B), the median sotrasib t max (1 hour) indicated rapid absorption and was similar to that observed following administration of sotorasib as a tablet (Treatment A). max , and t 1 / 2 Other PK parameters, including the maximum plasma concentration of sotorasib (t max ) and the mean half-life (t 1 / 2 ) was similar when sotorasib was administered as an oral tablet and when it was dispersed in 240 mL of water. inf The area under the curve from time 0 to infinity was 25300 h*ng / mL for sotorasib administered as a tablet and 26400 h*ng / mL for sotorasib administered as an aqueous dispersion. max The maximum plasma concentrations were 5440 ng / mL and 5860 ng / mL, respectively.

[0153] Sotorasib AUC when sotorasib was administered as a tablet predispersed in water (Treatment B) and as a tablet (Treatment A) last, AUC inf , and C max The ratios of GLSM (90%CI) for aqueous dispersion / tablet were 1.055 (0.950, 1.171), 1.049 (0.947, 1.162), and 1.080 (0.939, 1.243), respectively. AUC last , AUC inf , and C max The 90% CI for fell within and consistently spanned the 80% to 125% range. Pharmacokinetic parameters for the metabolite M24 were also similar between treatments.

[0154] Single doses of sotorasib, both as tablets dispersed in water and as tablets, were safe and well tolerated when administered to healthy subjects in the study. There were no serious adverse events and no treatment-emergent adverse events leading to premature withdrawal of subjects from the study. Three treatment-emergent adverse events were reported during the study: constipation, nausea, and vomiting, all of which were considered mild and related to sotorasib. All events resolved by the end of the study. There were no clinically significant findings in clinical laboratory evaluations, vital signs, or 12-lead ECGs during the study.

[0155] Conclusion: In summary, a total dose of 960 mg sotorasib was safe and well tolerated when administered to healthy subjects, both as a tablet when predispersed in water and when swallowed whole. Furthermore, when sotorasib was administered as a tablet dispersed in water, the AUC last , AUC inf , and C max were 1.055-fold, 1.049-fold, and 1.080-fold, respectively, when sotorasib was administered as a tablet.

[0156] Example 5 - Mechanical Analysis of Formulation Components Three dry granulated (roller compacted) placebo blends of microcrystalline cellulose (MCC, Avicel PH102) and lactose (lactose monohydrate, Lactose 313), and other individual ingredients including sotorasibe, Avicel PH102, and lactose, were evaluated for their mechanical properties using a Huxley Bertram (HB) compaction simulator. After compression, the tablets were measured for their ejected weight, thickness, and diameter. The tablets were then stored for a minimum of 48 hours to allow complete viscoelastic relaxation. The recovered dimensions were measured prior to diametrical compression testing, which was performed using the HB compaction simulator operating at a constant loading rate of 5 mm / min. The force required to cause diametric failure was recorded and used to calculate radial tensile strength values.

[0157] result: True Density: True density was measured using helium pycnometry. Placebo blend samples (approximately 400-500 mg) were retained after testing due to the non-destructive nature of this measurement.

[0158] [Table 40]

[0159] The true densities of the various dry granulated placebo blends matched well with the true densities of the major components, Avicel PH102 and Lactose 313.

[0160] Deformation Tendency: During compression, powder particles may deform either reversibly (elastic deformation) or irreversibly (plastic deformation and / or brittle fracture / fragmentation). Pharmaceutical powders are unique in that they often exhibit deformation by several different mechanisms with the relative contribution of each varying between materials. The deformation mode that predominates depends on a number of factors including the targeted compression pressure range, the rate at which the compression pressure is applied, and the inherent mechanical properties of the material. The objective of these studies is to identify the propensity of pharmaceutical blends to deform reversibly and to distinguish whether their irreversible deformation mechanisms are predominantly plastic and / or brittle.

[0161] Reversible deformation behavior can be either non-time-dependent or time-dependent. To evaluate both behaviors, a two-stage analytical procedure was used. First, non-time-dependent elastic deformation was quantified by calculating the change in solid fraction between the tablet volume at the minimum punch separation distance (in the die) and the tablet volume measured immediately after ejection. Negative values ​​reflect a decrease in sample density. Second, time-dependent elastic, or viscoelastic, deformation was quantified by calculating the change in solid fraction between the tablet volume measured immediately after ejection and the tablet volume after 48 hours of storage at ambient conditions.

[0162] [Table 41]

[0163] In all cases, the overall degree of reversible deformation is greater for tablets prepared at 50 MPa than for tablets prepared at 200 MPa. The negative values ​​reflect a decrease in sample density or an increase in tablet dimensions. This observation is likely driven by the presence of Avicel PH102 in the formulation. Without being bound to a particular theory, for a material such as Avicel PH102, increasing pressure changes the internal structure of the compact. This leads to an increase in the amount of energy stored within the compact, which drives reversible deformation. However, the increase in tensile strength that occurred at 200 MPa for Avicel PH102 (FIG. 12B) inhibits this reversible deformation, as demonstrated by the lower negative values ​​for all placebo blends at 200 MPa compared to 50 MPa. Overall, the data in Table 37 show that all three placebo blends have suitable elastic and viscoelastic deformation properties. Furthermore, the data supports the need for a plastic diluent (e.g., Avicel PH102) to produce acceptable tablets.

[0164] For sotorasib, values ​​for elastic and viscoelastic recovery could not be accurately calculated for comparison to the reference material data set. Tablets compressed to 200 MPa experienced flaking upon ejection, and the dimensions of the tablets exiting the die could not be adequately measured.

[0165] Compressibility: The ability to reduce the volume of a powder bed by application of an applied stress gives an indication of powder compressibility. This behavior is described in terms of tablet solid fraction as a function of compaction pressure (see Table 38). The interpretation of the data takes into account the change in solid fraction between the two pressure conditions. An increase in the difference in SF at high and low pressure is an indication of increased compressibility of the blend. The compressibility of all three placebo blends is at the high end (due to the presence of Avicel PH102) and shows a tendency to increase as the amount of Avicel PH102 in the placebo blend increases. Therefore, a plastic diluent to brittle diluent ratio of 3:1 is preferred, e.g., a 3:1 Avicel PH102 to lactose ratio.

[0166] [Table 42]

[0167] For sotorasibe, an applied pressure of approximately 145 MPa was required to produce tablets exiting the die with a solid fraction of 0.85. In comparison, Avicel PH102 required a pressure of 128 MPa, and lactose monohydrate required a pressure of 178 MPa. Thus, the presence of additional Avicel PH102 in the formulation should allow reduced compaction pressures to be used to achieve the target hardness / tensile strength. Thus, a plastic diluent to brittle diluent ratio of 3:1, e.g., Avicel PH102 to lactose ratio of 3:1, is preferred for sotorasibe formulations.

[0168] Compactibility and Tabletability: The ability of a powder bed to set or form a compaction provides an indication of powder compactibility. This behavior is illustrated as a plot of tablet radial tensile strength (RTS) as a function of tablet solid fraction (SF). To understand the fundamental material behavior, it is advantageous to compare materials at similar solid fraction levels. Higher radial tensile strength at the same solid fraction was observed for the 3:1 MCC to lactose placebo blend (Figure 12A). The compactibility of all three placebo blends can be classified as "low" because each blend was previously dry granulated. Tabletability is another relevant parameter that is useful for identifying the pressure required to achieve a particular tablet hardness or tensile strength. This behavior is illustrated as a plot of tablet radial tensile strength (RTS) as a function of compaction pressure (Figure 12B). Higher radial tensile strength at lower compaction pressure was observed for the 3:1 MCC to lactose placebo blend (Figure 12B). Based on compaction and tabletability profiles, a plastic diluent to friable diluent ratio of 3:1, e.g., a 3:1 Avicel PH102 to lactose ratio, is preferred for sotorasib formulations.

[0169] [Table 43]

[0170] The data in Table 39 show that as the amount of MCC in the blend increases, the measured radial tensile strength (RTS) at 150 MPa increases as well. Also, the compression pressure (CP) required to form a tablet with a radial tensile strength of 2 MPa is lower for the placebo blend with increasing MCC to lactose ratio. Both trends exhibit non-linear behavior. Overall, the data in Table 39 show that a 3:1 ratio of plastic diluent to brittle diluent is preferred, e.g., a 3:1 ratio of Avicel PH102 to lactose.

[0171] Sotorasib was determined to have a radial tensile strength of 1.62 MPa when compressed to a peak pressure of 150 MPa and a radial tensile strength of 1.59 MPa when compressed exiting a die at a solids fraction of 0.85 (see Table 39). The solids fraction at a theoretical strength value of 2 MPa is 0.85 for sotorasib, indicating a high level of compressibility combined with a very low level of compactibility. Available data indicates that sotorasib is a very poor interparticle bond former and therefore would benefit from a 3:1 plastic diluent to brittle diluent ratio, e.g., 3:1 MCC:lactose ratio, at drug loadings up to 20%. For certain formulations provided herein at 20% drug loading, the ratio of plastic diluent (e.g., Avicel PH102) to friable diluent (e.g., lactose) plus sotorasib is 1.46:1 (see Formulations No. 6, No. 7, and No. 8 in Example 1 and Table 40 in Example 6).

[0172] A traditional approach to increasing drug loading would be, for example, to keep the ratio of plastic diluent to brittle diluent the same and reduce both to accommodate higher drug loading. As previously noted in Table 39, reducing the weight of the plastic diluent results in lower tensile strength and requires higher compression pressure to produce acceptable tablets. Due to the lower tensile strength, reducing the weight of this plastic diluent is an inherent liability for higher drug loadings made using traditional approaches. Furthermore, the Carr index of these higher drug loading formulations is unfavorable, indicating processability challenges (see Carr index for formulations 2 and 3 in Table 40 of Example 6). Therefore, it is preferred to maintain the ratio of plastic diluent to brittle diluent and sotorasib together at 1.4:1 to 1.5:1 while increasing drug loading. Maintaining this ratio is not feasible using the traditional approach described above.

[0173] The similarity in mechanical properties between sotorasib and lactose is depicted in Figure 13A (compactability) and Figure 13B (tabletability). The similarity in processability between sotorasib and lactose is depicted in Figure 14A (flow energy) and Figure 14B (volume change rate) in Example 6. These data provide an unexpected and surprising alternative approach to increase drug loading while maintaining processability (see Carr Index for Formulations #4, #5, #9a, #9b, #10a, and #10b in Table 40 in Example 6). This approach involves replacing a brittle diluent, e.g., lactose, with sotorasib while keeping the ratio of plastic diluent (e.g., MCC) to brittle diluent (e.g., lactose) plus sotorasib constant at 1.4:1 to 1.5:1 (see #4, #5, #9a, #9b, #10a, and #10b in Example 1).

[0174] Example 6 - Flow energy and volume change studies This example describes experiments that were performed to evaluate the flow energy and compressibility of some of the formulations described in Example 1.

[0175] Flow energy (stable and variable flow) was measured using a powder rheometer. Bulk powder was dispensed into a test cell. The material was preconditioned with a blade to remove any packaging or storage history and achieve the inherent bulk density of the powder. The blade was passed through the blend at various speeds to determine the amount of energy required to pass through the powder bed. Stability tests are performed with multiple passes at a single blade speed (e.g., 100 mm / sec). Variable tests are performed with decreasing blade speeds (e.g., 100, 70, 40, 10 mm / sec). Stability and variable test data were reported in a single plot showing total energy in mJ versus test number (Figure 14A).

[0176] The volume change rate was measured using a powder rheometer. The bulk powder was dispensed into a test cell. The material was preconditioned with a blade to remove any packaging or storage history and achieve the powder's inherent bulk density. A vented piston was inserted into the test cell and an increasing stress was applied on the powder bed while the volume change was measured. The data is reported in a single plot showing the volume change rate versus the applied normal stress in kPa (Figure 14B).

[0177] As shown in Figures 14A and 14B, lactose (a brittle diluent) and sotorasib have similar properties (i.e., stability / variable flow energy and volume change rate). This data suggests that sotorasib can replace brittle components in formulations, such as brittle diluents (e.g., lactose). This replacement assists in maintaining certain manufacturability properties, such as flowability, of the initial blend of the formulations disclosed herein.

[0178] Carr Index: In a free-flowing powder, the bulk density and tapped density will be similar values, and therefore the Carr index will be small. On the other hand, for poorly flowing powders with more interparticle interactions, the bulk density will be higher than the tapped density, and the Carr index will increase. To measure the bulk volume, the powder was dispersed in a cylinder. The uncompacted apparent or bulk volume (V) of the formulation was oThe tap volume was measured using a tap density tester. Approximately 10, 500, and 1250 taps were performed on the powder samples, and V 10 , V 500 , and V 1250 The volume was recorded. 500 and V 1250 If the difference between is less than 1% of the cylinder volume, V 1250 The final tap volume (V f ) was reported. 500 and V 1250 If the difference between the measurements exceeded 1%, 1250 taps were repeated until the difference between subsequent measurements was 1% or less. Finally, the Carr index was calculated as follows (results are shown in Table 40):

number

[0179] result The Carr index of the initial blend (before granulation) was used for relative comparison of flow between the initial sotorasib formulation blends listed in Table 40.

[0180] [Table 44]

[0181] The data demonstrate that by maintaining the ratio of plastic diluent (%, w / w) to brittle diluent (% w / w) plus sotorasib (% w / w) between 1.4:1 and 1.5:1, the flow properties of the 30%, 32%, and 40% (w / w) high drug load formulations of sotorasib (Formulations No. 4, No. 5, No. 9a, No. 9b, No. 10a, and No. 10b) as indicated by the Carr index values ​​could be maintained similar to that of the 20% (w / w) sotorasib formulation (Formulations No. 6, No. 7, and No. 8). In contrast, the high drug load formulations (Formulations No. 2 and No. 3) that keep the ratio of plastic diluent to brittle diluent constant (3:1) show poor flow properties as indicated by the higher Carr index values.

[0182] Conclusions - Overall, the data presented in Example 5 and Example 6 demonstrate the benefit of alternative approaches to achieve high drug loading formulations (Formulations No. 4, No. 5, No. 9a, No. 9b, No. 10a, and No. 10b).
