FIELD

[0002] This disclosure provides novel bifunctional compounds for proteolytically degrading targeted Bruton's tyrosine kinases (BTK) and methods for treating diseases modulated by BTK. BACKGROUND

[0003] B cell receptor (BCR) signaling controls B cell development, as well as mature B cell activation, signaling, and survival. Mis-regulation of the BCR signaling pathway is associated with numerous disease indications involving B cell function, and targeting B cells and BCR signaling has clear therapeutic potential (Woyach, et al ; Blood, 120(6); 1175-1184, 2012). For example, depletion of B cells with monoclonal antibodies targeting CD20 has significant effects in treatment of B cell malignancies and auto-immune and inflammatory diseases (Cang, et al; J Hematolo Oncol. 5; 64, 2012.).

[0004] BTK is a member of the TEC family of kinases and is a crucial signaling hub in the BCR pathway. Mutations in BTK result in X-linked agammaglobulinaemia (XLA), in which B cell maturation is impaired, resulting in reduced immunoglobulin production (Hendriks, ef al; Expert Opin Ther Targets 15; 1002-1021, 2011). The central role of BTK in B cell signaling and function makes BTK an attractive therapeutic target for B cell malignancies as well as autoimmune and inflammatory diseases. Ibrutinib, a covalent inhibitor of BTK, has been approved to treat chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL) rand other B cell malignancies, as well as graft-versus-host disease (GVHD) (Miklos, ef al; Blood, 120(21); 2243-2250, 2017). Currently, ibrutinib and second-generation BTK inhibitors are being investigated for oncology and immune-related indications such as rheumatoid arthritis (Akinleye, ef al.; J of Hematolo Oncol. 6: 59, 2013; Liu, et al.; J Pharm and Exper Ther. 338(1): 154-163. 2011; Di Paolo, ef al.; Nat Chem Biol. 7(1): 41-50, 2011).

[0005] As an alternative to stoichiometric inhibition, proteolytic degradation of BTK could have dramatic consequences for B cell function by effectively blocking BCR signaling. Removal of BTK protein would eliminate BTK kinase activity as well as any protein interaction or scaffolding function of BTK. Specific degradation of BTK could be accomplished using heterobifunctional small molecules to recruit BTK to a ubiquitin ligase and thus promoting ubiquitylation and proteasomal degradation of BTK. Thalidomide derivatives, such as lenalidomide or pomalidomide, can be used to recruit potential substrates to cereblon (CRBN), a component of a ubiquitin ligase complex. This unique therapeutic approach could present a mechanism of action for interfering with BTK activity and BCR signaling that is distinct from the mechanism of stoichiometric BTK inhibition. Furthermore, this degradative approach could effectively target the C481S mutated form of BTK, which mutation has been clinically observed and confers resistance to inhibition by ibrutinib (Woyach, et al.; Blood, 120(6): 1175- 1184, 2012).

As described herein, compounds herein can optionally be substituted with one or more substituents, such as are illustrated generally above, or as exemplified by particular classes, subclasses, and species of the description. As described herein, the variables R, R!, R?, L,Y, and Z, and other variables contained in Formula (A), (B), (C), (D), (E), (F), (G), (H), (3), (K), M), (X), (I), (I-A), (I-B), (II), (II-A), (II-B), (III), and (IV) described herein encompass specific groups, such as alkyl and aryl.

Each substituent of a specific group is further optionally substituted with one to three of halo, cyano, oxo, alkoxy, hydroxy, amino, nitro, aryl, cycloaliphatic, heterocycloaliphatic, heteroaryl, haloalkyl, and alkyl. For instance, an alkyl group can be substituted with alkylsulfanyl and the alkylsulfanyl can be optionally substituted with one to three of halo, cyano, oxo, alkoxy, hydroxy, amino, nitro, aryl, haloalkyl, and alkyl. As an additional example, the cycloalkyl portion of a (cycloalkyl)carbonylamino can be optionally substituted with one to three of halo, cyano, alkoxy, hydroxy, nitro, haloalkyl, and alkyl. When two alkoxy groups are bound to the same atom or adjacent atoms, the two alkxoy groups can form a ring together with the atom(s) to which they are bound.

[0094] As used herein, the term "substituted," whether preceded by the term "optionally" or not, refers generally to the replacement of hydrogen atoms in a given structure with the radical of a specified substituent. Specific substituents are described above in the definitions and below in the description of compounds and examples thereof. Unless otherwise indicated, an optionally substituted group can have a substituent at each substitutable position of the group, and when more than one position in any given structure can be substituted with more than one substituent selected from a specified group, the substituent can be either the same or different at every position. A ring substituent, such as a heterocycloalkyl, can be bound to another ring, such as a cycloalkyl, to form a spiro-bicyclic ring system, for example, both rings share one common atom, Non-limiting examples of spiro heterocycloalkyls include HN XC HN Cn WN X MH A \ \ f 2,8-diazaspiro[4.5]decane . 2,7-diazaspiro[3.5]nonane . 3,9-diazaspiro[5.5]undecane . \ NH J xX 3-azaspiro[5.5]Jundecane . and 2-oxa-6-azaspiro[3.4Joctane

[0095] As one of ordinary skill in the art will recognize, combinations of substituents envisioned by this description are those combinations that result in the formation of stable or chemically feasible compounds.

[0096] As used herein, the phrase "stable or chemically feasible" refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and their recovery, purification, and use for one or more of the purposes disclosed herein. In some embodiments, a stable compound or chemically feasible compound is one that is not substantially altered when kept at a temperature of 40 °C or less, in the absence of moisture or other chemically reactive conditions, for at least a week.

[0097] As used herein, an "effective amount" is defined as the amount required to confer a therapeutic effect on the treated patient, and is typically determined based on age, surface area, weight, and condition of the patient. The interrelationship of dosages for animals and humans (based on milligrams per meter squared of body surface) is described by Freireich et al., Cancer Chemother. Rep., 50: 219 (1966). Body surface area may be approximately determined from height and weight of the patient. See, e.g., Scientific Tables, Geigy Pharmaceuticals, Ardsley, New York, 537 (1970). As used herein, "patient" refers to a mammal, including a human.

[0098] As used herein, the term “about” means within + 10% of a value. For example, a dose that is about 100 mg / kg provides that the does can 90 mg / kg to 110 mg / kg. By way of further example, an amount of an additional therapeutic agent ranging from about 50% to about 100% provides that the amount of additional therapeutic agent ranges from 45-55% to 90-110%. A person of skill in the art will appreciate the scope and application of the term “about” when used to describe other values disclosed herein.

[0099] Unless otherwise stated, structures depicted herein also are meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the (R)- and (S)- configurations for each asymmetric center, (Z)- and (E)- double bond isomers, and (Z)- and (E)- conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the description. Alternatively, as used herein, “enantiomeric excess (ee)” refers to a dimensionless mol ratio describing the purity of chiral substances that contain, for example, a single stereogenic center. For instance, an enantiomeric excess of zero would indicate a racemic (e.g., 50:50 mixture of enantiomers, or no excess of one enantiomer over the other). By way of further example, an enantiomeric excess of ninety-nine would indicate a nearly stereopure enantiomeric compound (i.e., large excess of one enantiomer over the other). The percentage enantiomeric excess, % ee = ([(R)-compound]-[(S)-compound]) / ([(R)-compound]+[(S)-compound]) x 100, where the (R)- compound > (S)-compound; or % ee ([(S)-compound]-[(R)-compound]) / ([(S)- compound]+[(R)-compound]) x 100, where the (S)-compound > (R)-compound. Moreover, as used herein, “diastereomeric excess (de)” refers to a dimensionless mol ratio describing the purity of chiral substances that contain more than one stereogenic center. For example, a diastereomeric excess of zero would indicate an equimolar mixture of diastereoisomers. By way of further example, diastereomeric excess of ninety-nine would indicate a nearly stereopure diastereomeric compound (i.e., large excess of one diastereomer over the other). Diastereomeric excess may be calculated via a similar method to ee. As would be appreciated by a person of skill, de is usually reported as percent de (% de). % de may be calculated in a similar manner to % ee.

[00261] Pharmaceutical Compositions

[00262] The compounds described herein can be formulated into pharmaceutical compositions that further comprise a pharmaceutically acceptable carrier, diluent, adjuvant, or vehicle. In one embodiment, this disclosure provides a pharmaceutical composition comprising a compound described above, and a pharmaceutically acceptable carrier, diluent, adjuvant, or vehicle. In one embodiment, this disclosure is a pharmaceutical composition comprising an effective amount of a compound of this disclosure or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier, diluent, adjuvant, or vehicle. Pharmaceutically acceptable carriers include, for example, pharmaceutical diluents, excipients, or carriers suitably selected with respect to the intended form of administration, and consistent with conventional pharmaceutical practices.

[00263] According to another embodiment, the description provides a composition comprising a compound herein or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier, adjuvant, or vehicle. Pharmaceutical compositions of this description comprise a therapeutically effective amount of a compound of Formula (A1), (A), (B), (C), (D), (D-1), (D-2), (E), (F), (G), (H), (3), (K), (M), (I), (I-A), (I-B), (II), (I-A), (II-B), (III), (IV), and / or (X) wherein a "therapeutically effective amount" is an amount that is (a) effective to measurably degrade BTK (or reduce the amount of BTK) in a biological sample or in a patient; or (b) effective in treating and / or ameliorating a disease or disorder that is mediated by BTK.

[00264] The term "patient," as used herein, means an animal, alternatively a mammal, and alternatively a human.

[00265] It also will be appreciated that certain compounds of this disclosure can exist in free form for treatment, or where appropriate, as a pharmaceutically acceptable derivative (e.g., a salt) thereof. According to this disclosure, a pharmaceutically acceptable derivative includes, but is not limited to, pharmaceutically acceptable prodrugs, salts, esters, salts of such esters, or any other adduct / educt or derivative that upon administration to a patient in need is capable of providing, directly or indirectly, a compound as otherwise described herein, or a metabolite or residue thereof

[00266] As used herein, the term "pharmaceutically acceptable salt" refers to those salts that are, within the scope of sound medical judgement, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, and the like.

[00267] Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this description include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts include salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid; or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid; or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N7(Ci14 alkyl)s salts. This description also envisions the quaternization of any basic nitrogen-containing groups of the compounds disclosed herein. Water or oil-soluble or dispersable products may be obtained by such quaternization. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate.

[00268] A pharmaceutically acceptable carrier may contain inert ingredients that do not unduly inhibit the biological activity of the compounds. The pharmaceutically acceptable carriers should be biocompatible, for example, non-toxic, non-inflammatory, non-immunogenic, or devoid of other undesired reactions or side-effects upon the administration to a subject. Standard pharmaceutical formulation techniques can be employed.

[00269] The pharmaceutically acceptable carrier, adjuvant, or vehicle, as used herein, includes any and all solvents, diluents, or other liquid vehicle, dispersion or suspension aids, surface active agents, isotonic agents, thickening or emulsifying agents, preservatives, solid binders, lubricants, and the like, as suited to the particular dosage form desired. Remington's Pharmaceutical Sciences, Sixteenth Edition, E. W. Martin (Mack Publishing Co., Easton, Pa., 1980) discloses various carriers used in formulating pharmaceutically acceptable compositions and known techniques for the preparation thereof. Except insofar as any conventional carrier medium is incompatible with the compounds described herein, such as by producing any undesirable biological effect or otherwise interacting in a deleterious manner with any other component(s) of the pharmaceutically acceptable composition, the use of such conventional carrier medium is contemplated to be within the scope of this description. As used herein, the phrase "side effects" encompasses unwanted and adverse effects of a therapy (e.g, a prophylactic or therapeutic agent). Side effects are always unwanted, but unwanted effects are not necessarily adverse. An adverse effect from a therapy (e.g., prophylactic or therapeutic agent) might be harmful, uncomfortable, or risky. Side effects include, but are not limited to, fever, chills, lethargy, gastrointestinal toxicities (including gastric and intestinal ulcerations and erosions), nausea, vomiting, neurotoxicities, nephrotoxicities, renal toxicities (including such conditions as papillary necrosis and chronic interstitial nephritis), hepatic toxicities (including elevated serum liver enzyme levels), myelotoxicities (including leukopenia, myelosuppression, thrombocytopenia and anemia), dry mouth, metallic taste, prolongation of gestation, weakness, somnolence, pain (including muscle pain, bone pain, and headache), hair loss, asthenia, dizziness, extra-pyramidal symptoms, akathisia, cardiovascular disturbances, and sexual dysfunction.

[00270] Some examples of materials that can serve as pharmaceutically acceptable carriers include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins (such as human serum albumin), buffer substances (such as tween 80, phosphates, glycine, sorbic acid, or potassium sorbate), partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes (such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, or zinc salts), colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, polyacrylates, waxes, polyethylene- polyoxypropylene-block polymers, methylcellulose, hydroxypropyl methylcellulose, wool fat, sugars such as lactose, glucose, and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose, and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil, and soybean oil; glycols such a propylene glycol or polyethylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring, and perfuming agents. Preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.

[00271] As used herein, the term "measurably degrade," means a measurable reduction in (a) BTK activity, between a sample comprising a compound of this description and a BTK and an equivalent sample comprising a BTK in the absence of said compound; or (b) the concentration of the BTK in a sample over time. ADMINISTRATION

[00272] The compositions of this disclosure are administered orally. The pharmaceutically acceptable compositions of this description may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions, or solutions. In the case of tablets for oral use, carriers commonly used include lactose and com starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring, or coloring agents also may be added.

[00273] Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compounds herein, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions also can include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

[00274] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound herein is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and / or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid; b) binders such as carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia; c) humectants such as glycerol; d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; e) solution retarding agents such as paraffin; f) absorption accelerators such as quaternary ammonium compounds; g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate; h) absorbents such as kaolin and bentonite clay; and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets, and pills, the dosage form also may comprise buffering agents.

[00275] Solid compositions of a similar type also may be employed as fillers in soft and hard- filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. Solid dosage forms optionally may contain opacifying agents. These solid dosage forms also can be of a composition such that they release the active ingredient(s) only, for example, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type also may be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.

[00276] The active compounds herein also can be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings, and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose, or starch. Such dosage forms also may comprise, as is normal practice, additional substances other than inert diluents, for example, tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms also may comprise buffering agents. They may optionally contain opacifying agents and also can be of a composition such that they release the active ingredient(s) only, for example, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes.

[00277] The compounds of the description are formulated in dosage unit form for ease of administration and uniformity of dosage. As used herein, the phrase "dosage unit form" refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of this disclosure will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex, and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts.

[00278] The amount of the compounds of this disclosure that may be combined with the carrier materials to produce a composition in a single dosage form will vary depending upon the host treated, the particular mode of administration, and other factors. The compositions should be formulated so that a dosage of between 0.01 - 100 mg / kg body weight / day of the compound or inhibitor can be administered to a patient receiving these compositions.

[00279] Depending upon the particular condition, or disease, to be treated or prevented, additional therapeutic agents, which are normally administered to treat or prevent that condition, also may be present in the compositions of this disclosure. As used herein, additional therapeutic agents that are normally administered to treat or prevent a particular disease, or condition, are known as "appropriate for the disease, or condition, being treated."

[00280] For example, chemotherapeutic agents or other anti-proliferative agents may be combined with the compounds of this disclosure to treat proliferative diseases and cancer. Examples of known chemotherapeutic agents include, but are not limited to, PI3K inhibitors (e.g., idelalisib and copanlisib), BCL-2 inhibitors (e.g., venetoclax), BTK inhibitors (e.g., ibrutinib and acalabrutinib), etoposide, CD20 antibodies (e.g., rituximab, ocrelizumab, obinutuzumab, ofatumumab, ibritumomab tiuxetan, tositumomab, and ublituximab), aletuzumab, bendamustine, cladribine, doxorubicin, chlorambucil, prednisone, midostaurin, lenalidomide, pomalidomide, checkpoint inhibitors (e.g. ipilimumab, nivolumab, pembolizumab, atezolizumab, avelumab, durvalumab), engineered cell therapy (e.g., CAR-T therapy - Kymriah®, Yescarta®), Gleevec™, adriamycin, dexamethasone, vincristine, cyclophosphamide, fluorouracil, topotecan, taxol, interferons, and platinum derivatives.

[00472] BTK CTMs were added to cells in round-bottom 96-well plates with a final DMSO concentration of >0.2% and were incubated at 37 °C and 5% CO: for four hours. BTK levels were determined using Cisbio Total-BTK HTRF (Homologous Time-Resolved Fluorescence) kit (63ADKO64PEG) according to the manufacturer’s protocol. Briefly, cells were incubated in 1X supplied lysis buffer for 30 minutes. In an opaque white low volume 96-well plate (Cisbio, 66PL96005), cell lysate was combined with two different specific BTK antibodies, one conjugated with Eu**-Cryptate FRET donor and one conjugated with d2 FRET acceptor. Assay controls include wells containing cell lysate with only the Eu’>*-Cryptate FRET donor antibody and wells containing both HTRF antibodies and lysis buffer without cells or control lysate provided by Cisbio. HTRF ratio was calculated as (acceptor signal at 665 nm / donor signal at 620 nm) x 10*. Background HTRF levels were determined from the control well containing the donor, but no acceptor, antibody. Background HTRF levels were subtracted from all samples. Readouts were reported as HTRF levels relative to HTRF levels of DMSO- treated cells. Four-parameter non-linear regressions were performed in GraphPad Prism 7.02 to obtain DC50 values.

[00473] As shown in FIG. 1, robust, time-dependent degradation of BTK was observed in multiple cell lines and primary human B cells in the presence of a compound provided herein. As shown in FIG. 2, several compounds provided herein induced degradation of BTK in Ramos cells expressing wild-type BTK or ibrutinib-resistant C4818 mutant BTK.

[00482] Cell viability was determined using CellTiter-Glo 2.0 Luminescent Cell Viability Assay (Promega, G9242), which quantitates the amount of ATP present as a proxy for the number of viable cells in culture. Cells were plated with densities between 2000-4000 cells per well in 96-well plates. Serial dilutions of BTK CTMs or comparator compounds were added with a final DMSO concentration of >0.3% and were incubated at 37 °C and 5% CO: for seventy-two hours. CellTiter-Glo reagent was added to cells at a dilution of 1:20, and the plate was incubated ten minutes at room temperature prior to reading the luminescence signal using an EnVision plate reader. Controls included cells treated with DMSO and wells that contained no cells, only media. Background luminescence signal was determined by control wells containing no cells, only media, and was then subtracted from all sample wells. Luminescence values were then normalized to DMSO-treated wells and reported at proportion viable cells.

[00483] As shown in FIG. 4, wild-type BTK cells were sensitive to a compound provided herein and to ibrutinib. Mutant C4813 BTK cells retained sensitivity to the compound provided herein but were less sensitive to ibrutinib.

[00485] B Cell Activation Assay

[00486] Evaluate effects of BTK degradation on B cell receptor signaling

[00487] Frozen human peripheral blood mononuclear cells (PBMCs) were thawed and treated with DMSO or compound for four hours and then stimulated for 18 hours with 10 pg / ml anti- IgM (Jackson Immunoresearch 109-006-129), and an additional DMSO-treated sample was left unstimulated. Compound was present throughout the stimulation. Cells were stained with Live / Dead dye (Fisher L34976) and then fluorophore-conjugated antibodies against CD20 (Biolegend 302330), CD3 (BD Pharmingen 557705), CD86 (Biolegend 305416) and CD69 (Biolegend 310906). Stained cells were fixed in PFA and run on an Attune NxT Acoustic Focusing Flow Cytometer (Thermo-Fisher A29004), and data was analyzed using FlowJo (v10.5.3) and GraphPad Prism (v7.00) software. Single live lymphocytes were gated for B cells (CD20+CD3-) and T cells (CD3+CD20-), and the geometric mean fluorescence intensity (MFI) of CD86 and CD69 was calculated for each population. The MFI of the unstimulated sample was used to quantify baseline activation.

[00488] As shown in FIG. 5, compound-mediated degradation of BTK prevented anti-IgM- induced upregulation of activation markers CD69 and CD86 on B cells.

[00490] Cellular Aiolos Degradation Assay

[00491] In vitro cellular screening to determine IMiD activity

[00492] Frozen human peripheral blood mononuclear cells (PBMCs) were thawed and treated with DMSO or compound for twenty-four hours and then fixed and permeabilized using a Foxp3 / Transcription Factor Fixation / Permeabilization Kit (eBioscience, 00-5523). Cells were stained with fluorophore-conjugated antibodies against CD20 (Biolegend 302330), CD3 (BD Pharmingen 552127), and Aiolos (Biolegend 371106). An additional set of DMSO-treated PBMCs was stained for CD20, CD3, and an AlexaFluor 647-conjugated mouse IgG1 isotype control antibody (Biolegend 400136). Stained cells were run on an Attune NxT Acoustic Focusing Flow Cytometer (Thermo-Fisher A29004), and data was analyzed using FlowJo (v10.5.3) and GraphPad Prism (v7.00) software. Single lymphocytes were gated for B cells (CD20+CD3-) and T cells (CD3+CD20-), and the geometric mean fluorescence intensity (MFI) of Aiolos was calculated for each population. The MFI of the isotype control was calculated for each population and used to quantify background staining. Percent Aiolos degradation was calculated for each compound-treated sample using the following equation: %Degradation = 100*(Sample MFI-Isotype MFI) / (DMSO MFI-Isotype MFI).

[00493] Exemplary results are shown in FIG. 9.

[00495] Mouse PD assays

[00496] Determine whether CTMs catalyze BTK degradation in vivo

[00497] A method of determining the pharmacodynamic profile of BTK degraders was performed by dosing either CD-1 or BALB / c mice with CTM. The CTM was prepared in a suitable formulation and was administered via oral gavage (PO) at a suitable dose level and frequency as informed by prior pharmacokinetic and tolerability studies. Following administration of CTM, BTK levels in blood or splenocytes are measured using flow cytometry or HTRF. For assessment of BTK levels via flow cytometry, either whole blood or splenocytes were first treated with ACK RBC lysis buffer to facilitate lysing of red blood cells. Remaining cells were then stained with fluorophore-conjugated antibodies against CD45, TCR beta and CD45R (B220). Cell pellets were washed with 1x PBS, fixed, and permeabilized for twenty- four hours with Foxp3 / Transcription Factor Fixation / Permeabilization Kit. Cells were then stained intracellularly with unconjugated BTK antibody and detected with a fluorophore- conjugated secondary antibody. Stained cells were run on an Attune NxT Acoustic Focusing Flow Cytometer (Thermo-Fisher A29004), and data was analyzed using FlowJo (v10.5.3) and GraphPad Prism (v7.00) software. Lymphocytes were gated for B cells defined as CD45+ TCR beta- B220+ and T cells as CD45+ TCR beta+ B220-. The BTK geometric mean fluorescence intensity (MFI) was calculated for B and T cells. Percent BTK degradation for each compound- treated sample was calculated using the equation described below: % Degradation = 100*(Treated sample B cell BTK MFI- treated sample T cell BTK MFI) / Vehicle B cell BTK MFI-Vehicle T cell BTK MFI)

[00498] As shown in FIG. 6, a dose-proportional decrease in BTK levels was observed in splenocytes after six hours of treatment and was associated with compound exposure in plasma. As shown in FIG. 7, dose- and dimt-dependent reduction in BTK levels were observed in circulating murine B cells after a single oral dose.

[00500] TMDS8 Xenograft Efficacy Studies

[00501] Evaluate anti-tumor effects of BTK degradation in vivo

[00502] The anti-tumor activity of CTM and Ibrutinib was evaluated in CB.17 SCID female mice bearing either TMD8 or TMD8 BTK®*!'S tumor cells. Mice were inoculated subcutaneously with either TMD8 or TMD8 BTK*'S cells and were randomized when tumors reached the predetermined size into treatment groups, vehicle control, CTM (30 mg / kg) or ibrutinib (30 mg / kg). Tumor bearing mice received either once a day (QD) or twice daily (BID) oral dose of CTM or ibrutinib.

[00503] Tumor and body weights were measured three times per week over a duration of twenty-one days. Tumor growth inhibition (% TGI) were calculated on the final day of measurement using the equation [1 — (T — To / C — To)] x 100, where T and C represent the mean size of tumors in the treated (T) and control (C) groups, and To refers to the tumor size at randomization.

[00504] As shown in FIG. 8, treatment with a compound herein caused tumor growth inhibition in a wild-type BTK xenograft model and in an ibrutinib-resistant C481S xenograft model.

[00513] This example evaluates the potency of CTM in degrading BTK-C481S. The BTK binding moieties utilized in CTMs bind to the BTK active site. This example evaluates whether the active site mutation C4818S affects CTM-induced degradation of BTK. The CTMs are potent towards Bruton’s tyrosine kinase-C4818S, but they are generally two- to three-fold more potent towards WT BTK compared to BTK-C4818S.

To evaluate potential therapeutic indications, BTK CTMs were assayed in models of Mantle Cell Lymphoma as with the TMDS cells (ABC-DLBCL) above.

[00519] This example evaluates the potency of CTMs in primary human B cells, rather than transformed or immortalized cancer cell lines. Primary cells are believed to be a physiologically relevant model. Thus, this example confirms the potency, kinetics, and level of BTK degradation in these cells in addition to the cell line models. Furthermore, this assay establishes that it is possible to monitor BTK degradation in primary human B cells, which can serve as a clinical biomarker.

[00521] lkaros and Aiolos degradation in Mantle Cell Lymphoma lines (Ikaros and Aiolos Flow Cytometry)

[00522] This example evaluates the IMiD activity of CTM:s in cellular models of Mantle Cell Lymphoma (MCL). Currently approved treatments for MCL include ibrutinib and lenalidomide, suggesting that targeting BTK and engaging CRBN are both viable therapeutic approaches in this indication. These assays are to determine potency of CTMs for degrading IMiD neo-substrates in cellular models of MCL and to generate data to inform efficacy studies in MCL xenografts. These data demonstrate IMiD activity for some compounds (e.g., compound 149) and not others (e.g., compound 130) and shows that IMiD neo-substrates are more potently degraded in Rec-1 cells compared to Mino cells, supporting us of Rec-1 cells in subsequent in vitro and in vivo studies.

[00523] As shown in FIGS. 10A and 10B, compound 44 has some effects on neo-substrate and ITK levels after twenty-four hours in TMD8 and / or MOLT4 cells.

[00524] As shown in FIGS. 10A and 10B, compound 72 does not effect CRBN neo-substrates but does affect ITK levels at twenty-four hours.

[00525] As shown in FIGS. 10A and 10B, compound 121 has minimal effects on CRBN neo- substrates and ITK at twenty-four hours.

[00526] As shown in FIGS. 11A and 11B, compounds 44 and 149 have some effect on CRBN neo-substrate and ITK levels in cells.

[00527] As shown in FIG. 12, other CTMs tested had slight effects on ITK levels but did not have IMiD activity, including compounds 72 and 130. Biological Example 15

[00528] TEC Kinase Degradation

[00529] This example assesses whether CTM treatment affects levels of off-target protein TEC kinase.

[00530] BTK and TEC kinase are two members of the TEC kinase family, and BTK inhibitors, such as ibrutinib, have been shown to affect TEC activity. This off-target effect of ibrutinib on TEC kinase has been implicated in the bleeding effects observed clinically with ibrutinib treatment. To determine effects of BTK CTMs on TEC levels in cells, K562 cells were treated for four hours with CTMs at concentrations between 0.026 — 2000 nM. TEC levels in cell lysate was assessed by western blot.

[00531] Tested CTMs have mild to moderate effects on TEC kinase levels in K562cells but exhibit more potent degradation of BTK than TEC as shown in FIGS. 13A-13D. The CTMs include compounds 44, 72, 149, and 130.

[00533] B cell activation assay (Flow Cytometry)

[00534] This example evaluates whether CTM treatment affects B cell receptor (BCR) signaling. BTK is activated downstream of the B cell receptor and leads to upregulation of activation markers CD86 and CD69 on the surface of B cells. These data illustrate that degradation of BTK can block this signaling pathway similar to inhibition of BTK with ibrutinib.

[00536] 7 cell activation assay (ELISA and Flow Cytometry)

[00537] This example evaluates whether CTMs with IMiD activity affect T cell activation. Activation of T cells is thought to be one way in which IMiDs, such as Lenalidomide and Pomalidomide can modulate the immune system. These assays were performed to assess whether BTK CTMs with and without IMiD activity affected activation of primary human T cells after stimulation of the T cell receptor with anti-CD3 / ati-CD28 stimulation. T cell activation was measured by IL-2 secretion (ELISA assay) and upregulation of activation markers CD25 and CD69 on the surface of T cells (flow cytometry). Data are presented as the fold-change of response relative to baseline (stimulation with anti-CD3 / anti-CD28 stimulation in the absence of compound).

[00538] Lenalidomide and Pomalidomide induce IL-2 secretion and increase expression of CD25 and CD69 above the baseline level (anti-CD3 / anti-CD28 stimulation alone).

[00539] Ibrutinib treatment results in decreases in IL-2 secretion and expression of CD25 and CD69 compared to baseline. As BTK is not present in T cells, this could be due to ibrutinib’s off-target effects on other kinases such as ITK.

[00540] CTMs with IMiD activity (such as compounds 44, 149, 30, and 25) increased IL-2 secretion but not to the level observed with IMiDs. Treatment with these CTMs resulted in unchanged or decreased levels of CD25 and CD69, potentially due to non-IMiD effects of the CTM, like affecting ITK.

[00541] These data suggest there is a correlation between IMiD neo-substrate degradation activity of certain CTMs and their phenotypic effects on T cell activation in terms of IL-2 secretion.

[00544] This example evaluates effects of CTM-mediated degradation on cell viability. Certain B cell malignancies have been shown to be dependent on BCR signaling and thus BTK for survival. Here, the ability of CTMs to affect viability in BTK-dependent cell lines was assessed. Mino and Rec-1 are models of Mantle Cell Lymphoma, which is sensitive to IMiDs. In these MCL cell lines, BTK CTMs affected degradation, and CTMs with IMiD activity (compounds 44 and 149) were more potent than a CTM with minimal IMiD activity (compound 130).

[00546] This example evaluates the effects of CTM-mediated degradation on cell viability. Certain B cell malignancies have been shown to be dependent on BCR signaling and thus BTK for survival. Here, the ability of CTMs to affect viability in BTK-dependent cell lines was assessed. The ABC-DLBCL cell line TMDS8 was very sensitive to BTK degradation or inhibition, while the TMDS cell line expressing the ibrutinib-resistant mutant BTK-C481S retained sensitivity to BTK degradation (~2-5 fold less sensitive than WT) but were not sensitive to BTK inhibition.

[00548] In vivo degradation of BTK in mouse PD experiments with oral dosing

[00549] This example evaluates in vivo activity of BTK CTMs via a direct mouse PD measurement following oral dosing

[00550] Various BTK CTMs demonstrate robust BTK degradation activity in vivo; activity varies from inactive compounds to compounds with sustained BTK degradation even twenty- four hours after a single oral dose; this data helped understand BTK degradation / resynthesis rates in vivo. Screens were completed at 90 mg / kg for six hours, and then changed to lower doses / longer time points after seeing strong BTK degradation activity with an initial set of compounds. This assay was useful in selecting compounds for in vivo efficacy experiments. The assay showed a good correlation between mouse PD results and in vivo efficacy in mouse tumor models.
