[0070] In various cases, secreted WNT ligands have been reported to engage cell surface receptors (e.g., LRP, FZD, etc.) in multiple cell types during mammalian development, and in a restricted set of adult cell populations, to drive a signal transduction pathway that leads to stabilization of cytosolic beta-catenin protein (see, e.g., Rim, EY, Clevers H, & Nusse R. The Wnt Pathway: From Signaling Mechanisms to Synthetic Modulators. Annual Reviews in Biochemistry, 2022: 91:15.1-15.28). It has been reported that engagement of the WNT receptor complex can lead to blockade of a constitutive ‘destruction complex’ that drives proteasome-mediated degradation of beta-catenin in the absence of WNT ligand. In some cases, the ‘destruction complex’ has been reported to contain multiple proteins, including AXIN, adenomatous polyposis coli (APC), GSK3 and CK1, that cooperate to drive beta-catenin degradation. Following stabilization of cytosolic beta-catenin, it is reportedly translocated to the nucleus and activates a transcriptional program by virtue of interaction with members of the TCF transcriptional factor family (TCF1 / 3 / 4 and LEF1). The beta-catenin:TCF complex can bind to cognate deoxyribonucleic acid (DNA) sequences and drives a gene expression program involved in cell proliferation, stem cell maintenance, and epithelial- to-mesenchymal transition (EMT).

[0071] It has been reported that dysregulation of the WNT / beta-catenin pathway frequently occurs in human cancers (see, e.g., Zhong Z, Yu J, Virshup DM, Madan B. Wnts and the hallmarks of cancer. Cancer Metastasis Rev. 2020;39(3):625-45; Du P, Han, X. Report R-35. Analysis of the mutation prevalence of Wnt pathway genes and the relationship between APC / CTNNB1 mutations and Microsatellite Instability. 2023; etc.). WNT pathway mutations, including APC loss of function (LoF) mutations and CTNNB1 (beta-catenin) activating mutations, are reported to impact cancer cell proliferation, differentiation, and apoptosis (see, e.g..Stamos JL, Weis WI. The beta-catenin destruction complex. Cold Spring Harb Perspect Biol. 2013;5(l):a007898). It has been reported that APC LoF mutations can incapacitate the beta-catenin destruction complex and can lead to subsequent beta-catenin activation (see, e.g., Stamos JL, Weis WI. The beta-catenin destruction complex. Cold Spring Harb Perspect Biol. 2013;5(l):a007898). LoF mutations in APC, activating mutations in beta-catenin, along with other driver WNT pathway mutations, are frequently reported in common cancer types (see, e.g., Hoadley KA, Yau C, Hinoue T, et al. Cell-of-origin patterns dominate the molecular classification of 10,000 tumors from 33 types of cancer. Cell, 2018; 173(2):291 - 304.E6; Gajos-Michnicwicz A, Czyz M. Wnt signaling in melanoma. Int J Mol Sci. 2020;21(14):4852; Stewart DJ. Wnt signaling pathway in non-small cell lung cancer. J Natl Cancer Inst. 2014;106(l):djt356; Teeuwssen M, Fodde R. Wnt signaling in ovarian cancer sternness, EMT, and therapy resistance. J Clin Med. 2019;8(10): 1658; etc.). Analyses of The Cancer Genome Atlas (TCGA) dataset revealed that the prevalence of these WNT pathway-activating mutations (WPAMs) is 80.7, 33.1, 21.1 and 4.5-7.2% in CRC, liver cancer, gastric cancer and non-small cell lung cancer (NSCLC), respectively (see, e.g., Du P, Han, X. Report R-35. Analysis of the mutation prevalence of Wnt pathway genes and the relationship between APC / CTNNB1 mutations and Microsatellite Instability. 2023; Hoadley KA, Yau C, Hinoue T, et al. Cell-of-origin patterns dominate the molecular classification of 10,000 tumors from 33 types of cancer. Cell, 2018; 173(2):291 - 304.E6; etc.).

[0072] The functional relevance of key WPAM mutations in the initiation and maintenance of cancer has been reported preclinically. For instance, LoF mutations in the APC gene observed in patient colorectal tumor samples have been reported to drive tumorigenesis in cell and animal models of cancer (see, e.g., Bian J, Dannappel M, Wan C, et al. Transcriptional Regulation of Wnt / p-Catenin Pathway in Colorectal Cancer. Cells, 2020: 9:2125). Genetic perturbation of APC gene in mouse models is reported to lead to intestinal polyps and tumorigenesis, particularly in combination with additional cancer driver mutations, like KRAS, TP53 and SMAD4 (all of which have been reported to be commonly observed in CRC patients). It has been reported that restoration of wild-type APC, or complete blockade of beta-catenin activity (using short hairpin RNA [shRNA], CRISPR) in preclinical cancer models carrying APC mutations, leads to strong inhibition of cancer cell and tumor growth, and knockdown of TCF proteins in tumor cells with activated beta-catenin also leads to inhibition of cancer cell proliferation.

[0073] It has been reported that the majority of human colorectal cancer (>80%), and many cancers representing multiple additional indications (e.g., hepatocellular, gastric, endometrial and non-small cell lung cancers), harbor mutations in genes of the WNT / beta-catenin pathway. APC and CTNNB1 (encoding [3-catenin) are two of the most frequently mutated genes in this pathway. These mutations lead to the stabilization of beta-catenin at the protein level and the hyperactivation of its transcriptional activity in the nucleus of tumor cells, in complex with TCF family proteins.

[0074] Transcriptional programs driven by beta-catenin:TCF complex have been reported to activates multiple biological pathways that promote tumor growth including cell cycle regulators and the C-MYCtranscription factor, which itself is a well-described oncogenic driver (see, e.g., Rennoll S, Yochum G. 2015. Regulation of MYC gene expression by aberrant Wnt / B-cateninsignaling in colorectal cancer. World J Biol Chem. 6(4):290-300)). Directly blocking |3-catenin:TCF interaction offers a useful strategy to treat tumors carrying WPAMs. It has been an area of intense interest for decades, but few if any safe and effective therapeutics in this area have been reported and approved.

[0075] Various in vitro and in vivo assays have confirmed that 1-66 can modulate beta-catenin:TCF interactions and can inhibit tumor growth including in various PDX tumor models. Among other things, the present disclosure provides technologies, e.g., formulations, doses, dosage regimens, etc., for using 1-66 to treat cancers in human subjects.1-66

[0225] Those skilled in the art appreciate that various technologies are available for manufacturing and assessing provided technologies in accordance with the present disclosure. Described below are certain examples.

[0226] Example 1. Manufacturing of 1-66.

[0227] Those skilled in the art appreciate that various synthetic technologies may be utilized to prepare 1-66 including drug substance and drug products in accordance with the present disclosure. Certain useful technologies are presented below as examples. Various technologies described in, e.g., WO2022 / 261257, are also useful for preparing 1-66.

[0228] In some embodiments, the present disclosure provides technologies for manufacturing 1-66, e.g., for use as a drug substance.

[0229] Certain useful starting materials are described below as examples.Table E-l. Useful starting materials for 1-66 preparation.

[0230] In some embodiments, 1-66 is manufactured as described below as an example.

[0231] In some embodiments, 1-66 drug substance manufacturing employs three stages. In the first stage,1-66 is synthesized using a solid-phase peptide synthesis (SPPS) approach with standard Fmoc protecting group strategy where all synthetic operations are performed on solid support, including installation of the olefin and lactam staples. Proceeding from the C-terminal to the N-terminal, synthesis is initiated by attaching the C-terminal amino acid residue onto the insoluble support (resin). After the initial attachment, subsequent Fmoc-protected amino acid derivatives are attached sequentially to lengthen the protected peptide anchored to resin. The second stage encompasses cleavage from resin. In the third stage, the crude peptide is purified by preparative reverse-phase chromatography and the product-bearing fractions are lyophilized to afford 1-66 drug substance.

[0232] An overview of a synthetic process used for both the non-GMP batch for GLP toxicology studies as well as the GMP clinical batch, including the amide-forming steps and key stapling steps, is illustrated inScheme 1 and Scheme 2 below. Certain useful starting materials are described in Table E-l.

[0233] Scheme 1. SPPS Synthesis (Stage 1) of 1-66 to AA2 Including First Staple Installation.

[0235] Typically, each peptide synthesis cycle step involves a deblocking, coupling, and capping step. The lactam stapling is performed after the first ten amino acids have been assembled. This is done by deprotection of the alloc and allyl groups on Lys10and Glu14, respectively, using palladium-mediated deprotection conditions followed by amide bond formation using standard coupling agents (e.g., PyAOP, EDC, CDMT, etc. ). Following additional elongation of the peptide chain to AA2, a first ring-closing metathesis to generate the (i,i+7) staple is performed (e.g., in various preparations, the E-olcfin isomer). Then the last amino acid is installed, capped, and a second ring-closing metathesis is performed to generate the (i,i+3) staple (e.g., in various preparations, the Z-olefin isomer). Typically, one isomer is depicted, e.g., in schemes.

[0236] Following completion of the Stage 1 (SPPS) processing, 1-66 is cleaved from the solid-support using TFA / water, neutralized and solid phase extracted using Sepabeads (Stage 2). The extracted peptide is recovered by filtration for the purification process. 1-66 is purified by multi-step reverse-phase chromatography (Stage 3). The purified drug substance may be salt exchanged to provide the desired counterion before the purified solution is dried by lyophilization (Stage 4) to afford the substance before packaging in amber glass containers with Teflon-lined polypropylene screw caps and stored at -20°C ± 5 °C. A complete overview of an example manufacturing process is illustrated in Scheme 3 below.

[0237] Scheme 3. An Overview of All Manufacturing Stages.

[0238] Solid Phase Peptide Synthesis (SPPS) of the 1-66 drug substance can be performed according to procedures and protocols well-developed and used routinely for peptide synthesis. SPPS typically comprises the sequential assembly of protected amino acid derivatives to synthesize a peptide anchored onto solid support (resin). In some embodiments, addition of an amino acid to grow the peptide generally involves the following steps: removal of protective N-terminal Fmoc group from the previous amino acid; wash; couplingof the next activated amino acid; wash; acetylation (when necessary); and wash. Typically proceeding from the C-terminal to the N-terminal, these steps are repeated for each amino acid until the desired linear peptide is assembled onto resin.

[0239] In various preparations, at the start of the synthesis of 1-66 drug substance, Rink-amide MBHA resin is prepared by a deblocking reaction using piperidine / dimethylformamide (DMF), followed by the loading of the C-terminal amino acid (Fmoc- Ala-OH- H2O) onto resin in the presence of DMF / Oxymapuie / diisopropylcarbodiimide (DIC). Unreacted sites on the resin are capped, e.g., by an acetylation reaction using DMF / diisopropylcthylaminc (DIPEA) / acctic anhydride. A substitution test is performed after the loading reaction to assure acceptable loading of the Fmoc-Ala-OH- H2O onto resin. Each subsequent protected amino acid is added to grow the peptide by performing two reactions: [1] a deblocking reaction that removes the Fmoc group from the N-terminal amino acid derivative; and [2] a coupling reaction that attaches the next amino acid derivative. A capping reaction, e.g., an acetylation reaction is performed when necessary. These reactions are repeated iteratively to grow the peptide. The deblocking reaction is performed in the presence of pipcridinc / DMF. The coupling reaction is performed in the presence of Oxymapure / DIC / DMF. The acetylation reaction is performed in the presence of DMF / DIPEA / acetic anhydride. In-process checks (e.g., Ninhydrin test or chloranil test, and / or LC analysis) are performed after each reaction to assure the completeness of each reaction. Wash steps are applied at the end of each reaction to remove residual reaction reagents and solvents, and to prepare for the next reaction.

[0240] After the attachment of Fmoc-Asp5(OtBu)-OH, an allylic deprotection reaction followed by a lactamization reaction are performed to bridge Lys10and Glu14. The allylic deprotection reaction is performed in the presence of tetrakis(triphenylphosphine palladium (Pd(PPh3)4) / triphenylphosphine (PPPhaj / dimethylbarbituric acid (DMBA)Zdichloromethane (DCM). The lactamization reaction is performed in the presence of (7-Azabenzotriazol-l-yloxy)tripyrrolidinophosphonium hexafluorophosphate (PyAOP) / DMF / DIPEA. In-process checks are performed after each reaction to assure the completeness of each reaction. After the lactamization reaction, synthesis of the peptide resumes.

[0241] After the attachment of Fmoc-Asp2(OtBu)-OH, a ring closing metathesis (RCM) reaction is performed to connect B54to PyrS2”, in the presence of Hoveyda-Grubbs catalyst. In-process checks were performed to assure the completeness of each reaction. Synthesis of the peptide resumes with the attachment of Fmoc-PL3 ’-OH and its acetylation at the N-terminal. A second RCM reaction is performed to connect B54to PL31. The peptide -resin is dried under reduced pressure and elevated temperature.

[0242] Cleavage of peptide from resin and Solid Phase Extraction (SPE)

[0243] Crude 1-66 drug substance is cleaved from resin and deprotected by removal of the side-chain protective groups by acidolysis, in the presence of trifluoroacetic acid (TFA / I-EO. Spent resin is removed by filtration, the filtrate is neutralized, and subjected to solid phase extraction (SPE) using Sepabeads resin in the presence of ACN / NFEOAc. In-process checks are performed to assure the completeness of the extraction. The resin is collected and washed. The crude peptide is released from resin in the presence of ACN / H2O andseparated from spent resin by filtration for the purification steps. Various stereoisomer may be formed; 1-66 is the isomer that show various characterization data (e.g., NMR, HPLC, etc.) as described herein and is purified.

[0244] Purification by reverse phase chromatography

[0245] Crude 1-66 drug substance is purified by a three-step reverse phase chromatography (RPC) process (e.g., RPC 1, RPC 2, and RPC 3). The crude peptide (in a solution) is diluted 1:4 with ACN / NH4HCO3, then filtered through 2.4 pm filter and applied to the prepared HPLC column. Effluent from the column is monitored for UV absorption and fractions are collected when the product begins to elute. The fractions are assessed by analytical HPLC and pooled in such a way that the purity complies with the requirements for in-process controls. The fractions meeting the purity requirements are pooled for the next purification step. Side fractions not meeting the purity requirements are either pooled to a repeat of the purification steps or discarded.

[0246] The first purification step (RPC 1) is by preparative HPLC using a column of reverse phase media that has been washed and pre-equilibrated with ACN / NH4HCO3. The adsorbed peptide is eluted from the column by applying a gradient of ACN / NH4HCO3. Fractions are collected when the product starts to elute from the column and analyzed for peptide purity by analytical HPLC. RPC 1 fractions meeting the specified in-process control (IPC 1) acceptance criteria for purity (e.g., > 85%) are pooled for RPC 2 and kept at 2 - 8 °C until RPC 2. RPC 1 side fractions not meeting the purity acceptance criteria are either pooled to repeatRPC 1 or discarded.

[0247] The main pools from RPC 1 are diluted with an equal volume of NH4HCO3 and applied to the preparative HPLC column equilibrated with ACN / NH4HCO3. The adsorbed peptide is eluted from the column by applying a gradient of ACN / NaHjPCh, pH 8.0. Fractions are collected when the product starts to elute from the column and analyzed for peptide purity by analytical HPLC. RPC 2 fractions meeting the in- process control (IPC 2) acceptance criteria for purity (e.g., > 94% Pre-pool and > 95% Main pool) are pooled for RPC 3 and kept at 2 - 8°C until RPC 3. RPC 2 side fractions not meeting the purity acceptance criteria arc cither pooled to repeat RPC 2, pooled to repeat RPC 1 , or discarded. The pooled side fractions arc kept at 2 - 8°C until their respective next steps.

[0248] The main pools from RPC 2 are diluted with an equal volume of USP Purified water and applied to the preparative HPLC column equilibrated with ACN / NaH^PCL, pH 8.0. The adsorbed peptide is eluted from the column by applying a gradient of ACN / NH4HCO3. Fractions are collected when the product starts to elute from the column and analyzed for peptide purity by analytical HPLC. RPC 3 fractions meeting the in-process control (IPC 3) acceptance criteria for purity (e.g., > 94.5% Pre -pool and > 95.0% Main pool) arc pooled for the sodium conversion step and kept at ambient temperature until the sodium conversion step. RPC 3 side fractions not meeting the purity acceptance criteria are either pooled to repeat RPC 2, pooled to repeat RPC 1, or discarded. The pooled side fractions are kept at 2 - 8 °C until their respective next steps.

[0249] Sodium conversion and finished product isolation

[0250] The main pools from RPC 3 are combined, diluted 1:1 with Sterile Water for Irrigation, USP to the target peptide concentration range, and added to an appropriate amount of filtered sodium hydroxide solution required to convert the product to its trisodium form. The sodium form of the product is filtered through a 0.2 um filter for final lyophilization.

[0251] After final lyophilization is completed, the finished 1-66 drug substance (in powder form) is packaged in amber glass containers, capped with Teflon®-lined polypropylene screw caps, and stored at - 20°C ± 5°C.

[0252] In some cases, lyophilized 1-66 drug substance that did not meet a desired acceptance criteria as established in the desired drug substance specification can be subjected to re -purification. Re-purification is carried out, after reconstitution of the peptide in an appropriate solvent, by repeating the purification step(s), described above. After re-purification, the material obtained undergoes final lyophilization as described above.

[0253] In some embodiments, lyophilized 1-66 drug substance not meeting a desired acceptance criteria for residual solvents, salts, or water content established in the peptide drug substance specification may be subjected to re-lyophilization. Re-lyophilization is carried out, after reconstitution of the peptide, by repeating the lyophilization step, as described above.

[0254] In some embodiments, the following method is utilized for assessing 1-66 purity; in some embodiments, it is utilized for in-process control of preparative HPLC fractions.

[0255] Table E-2. A Useful HPLC Protocol.

[0256] Other in-process controls being used during the manufacturing process include monitoring to assure completion of each of the synthetic coupling reactions during the assembly of the protected peptide - resin precursor using Ninhydrin and / or Chloranil tests and / or RP-HPLC analysis; verifying purity / impurity profile of the product by RP-HPLC following the cleavage of the crude product from the resin; and verifying identity of the product by LC-MS following the cleavage of the crude product from the resin.

[0257] In some embodiments. 1-66 was isolated as the sodium salt and isolated by lyophilization as an amorphous solid.

[0258] Characterization

[0259] 1-66 is characterized by various technologies. Certain characterizations are presented as examples.10260] Ultra-High Performance Liquid Chromatography-Mass Spectrometry (UHPLC-MS) can be used to verify the monoisotopic mass of the 1-66 drug substance. A sample was analyzed on a Waters Xevo G2- XS QToF mass spectrometer to confirm the monoisotopic mass of a preparation. The theoretical monoisotopic mass is 2074.93 Da (as C102H134N18O25S2). The charged molecular- ion [M+2H]2+was observed during a mass spectral analysis: m / z calculated 1038.4677; observed 1038.47. The results confirm the theoretical molecular mass of 1-66.

[0261] Matrix-assisted Absorption and Desorption / Ionization-Time-of-flight tandem mass spectrometry (MALDI-TOF MS / MS) can be used to verify the amino acid sequence of 1-66. A sample was analyzed on a Bruker ultrafleXtreme MALDI-TOF Mass Spectrometer to confirm the monoisotopic mass and the peptide sequence. The results confirm the amino acid sequence of 1-66.

[0262] Chiral amino acid analysis (e.g., using GC / MS) can performed to determine chiral purity of various constituent amino acid residues, e.g., Ala, Npg, Asp, Phe, Lys, and BztA. In an analysis, the peptide is hydrolyzed in 6N deuterated solvents (DCI / D2O), suitably derivatized, and analyzed using GC-MS to determine each amino acid enantiomer. Racemization during hydrolysis and derivatization (sample prep) is paralleled by deuterium exchange in the a-position (deuterium label). The proportion of epimerized-aminoIllacid present in the 1-66 sample is represented by the relative amounts of the unlabeled form which is monitored by mass spectrometry. The results of the analysis confirm that the chiral and isomeric purity of all the standard L-amino acids present in 1-66 drug substance is high.

[0263] Table E-3. Amino Acid Enantiomeric Purity from An Analysis.

[0264] In some embodiments, the present disclosure provides 1-66 preparations with chiral amino acid purities about as described above. In some embodiments, enantiomeric purity of Ala is > about 99.9%, enantiomeric purity of Npg is > about 99.8%, enantiomeric purity of Asp is > about 99.9%, enantiomeric purity of Phe is > about 99.9%, enantiomeric purity of Lys is > about 99.9%, and / or enantiomeric purity of BztA is > about 99.7%.

[0265] Preparations of 1-66 may contain counterions. In some embodiments, sodium and ammonium content of batches manufactured was assessed by ion chromatography to confirm the identity and determine the quantity of the counter ion. For preparations prepared as sodium salt, identity of the sodium counter ion was confirmed which corresponds to approximately 3 equivalents per molecule and ammonium was not detected. For a preparation prepared as ammonium salt before lyophilization, ammonium content was below the theoretical level for the stoichiometric salt, indicating a possible disproportionation of the salt during lyophilization.

[0266] *H- andl3C Nuclear Magnetic Resonance Spectroscopy (NMR) technologies are utilized to confirm 1-66 identity and assess 1-66 preparations. For example, for a preparation, sample was dissolved in methanol-d4. 'H,l3C, COSY, TOCSY, NOESY, HSQC and HMBC data were acquired on a 900MHz Bruker AVANCE III system with a cryoprobe. Sample concentration was 10mg / 750pl. Observed 'H and13C signals are presented in the third and fourth columns in Table E-4. Without the intention to limited by them, possible assignments were also included in Table E-4 and the first and second columns.

[0267] Table E-4. 'H and13C Signals and Possible Assignments (MeOD at 25°C)

[0268] There is a strong and unambiguous NOE peak observed between the olefin protons 111 and 112. This peak is stronger than the NOE peak between neighboring aromatic protons 20 and 21, or 48 and 47 / 49. Without the intention to be limited by theory, since the distance between neighboring aromatic protons is about 2.5 A, the distance between 111 and 112 is likely shorter than 2.5 A. The two protons are drawn as cis configuration in various chemical structures of the present disclosure to represent these observations. Both proton and carbon peaks for 88 and 89 have similar chemical shift values on a 900MHz instrument.Traditional NOE experiments have not provided as much information about stereochemistry between the two protons. A combination of homonuclear decoupling experiment and simulation showed that the coupling constant between protons 88 and 89 is about 14Hz. The two protons are drawn as trans configuration in various chemical structures of the present disclosure to represent these observations. While stereoisomersexist, those skilled in the art readily appreciate that identity of 1-66 is established and confirmed by various data herein, e.g., NMR, HPLC, etc.

[0269] X-ray crystallography was used to characterize the structure of 1-66. The obtained data confirm the helical nature of 1-66 as it binds to [3-catenin. X-ray also confirmed the primary sequence of 1-66.

[0270] Secondary structure of 1-66 was analyzed using Microfluidic Modulation Spectroscopy (MMS). 1-66 at 20 mg / mL was analyzed in its formulation (10 mg / mL arginine; 33.6 mg / mL PEG-400; 1.2 mg / mL sodium phosphate monobasic; pH 8) on an AQS3®pro MMS production system (RedShiftBio, Boxborough, MA). The absolute absorbance spectrum and its second derivative plot of the peptide of a batch arc shown in Figure 14, (A) and (B), respectively. The major peak at 1662 cm1indicates that the secondary structure of the protein is dominated by a helical structure, with a mixed of a- and 3io-helix characters. This agrees with the crystal structure of 1-66. Quantitative analysis of the Higher Order Structure (HOS) fractional contributions (Figure 14, (C)) was performed by Gaussian curve deconvolution of the baseline-corrected second derivative plot, based on the secondary structural element designations shown below:

[0271] As shown in Figure 14, (C), roughly 56% of the structure of the batch is 3io-helix and 13% of the structure is a-helix, totaling 69% of helical content. The total percentage of helical structure also agrees with the crystal structure, showing 12 out of the 18 (67%) amide carbonyl groups are forming H-bonds responsible for the helical structure. The relatively higher 3 -helix content compared to a-helix can be explained by the crystal structure, which shows that some of the amide carbonyls have the potential to H-bonds (based on the calculated distance) with both the i+3 and i+4 amines, which can result in a mix of both 3 io- and a-helix characters. In solution, where the MMS measurements were taken, these H-bonding interactions can be dynamic and possibly shift to one character more than the other depending on the level of hydration.Examples of mixed a- / 3io-helix characters and the extended helix strand in an 1-66 crystal structure include H-Bond formation between Ac0and Npg3 / B54, H-Bond formation between Npg3and 3COOHF6 / Aib7, and residues 3Thi12, BztA13, and Glu14in the extended strand.

[0272] In certain preparations, 1-66 was isolated by lyophilization and no crystalline or polymorphic forms were observed. For example, a sample of a preparation (sodium salt) was assessed by XRPD using a Panalytical Empyrean diffractometer equipped with a Cu X-ray tube and a PIXcel 1D-Medipix3 detector system at ambient temperature in transmission mode and held between low density polyethylene films. Thefollowing parameters were used: range 3-40°29, step size 0.01313°, counting time 48sec, ~10min run time, counting time 23sec, ~5min run time. Samples were spun at 60 rpm during data collection. XRPD patterns were sorted and manipulated using HighScore Plus v4.9 software. The sample was found to be amorphous with no clear indication of crystallinity.

[0273] Thermal analysis can be utilized to assess 1-66 preparations. For example, Hyper-DSC was carried out to determine the glass transition temperature of an 1-66 preparation. The thermogram did not detect the glass transition temperature of the amorphous material. Hyper DSC analyses were carried out on a Perkin Elmer DSC8500 Differential Scanning Calorimeter. Accurately weighed samples were placed in crimped aluminum pans, closed but not gas tight. Each sample was heated and cooled under nitrogen over two cycles at a rate of 300 °C / minute using a set temperature range of -50 to 160 °C. Indium metal was used as the calibration standard.

[0274] Thermogravimetric differential thermal analysis (TG-DTA) can be utilized to assess 1-66 preparations. For a preparation, thermogravimetric analysis was carried out on a preparation and showed significant weight losses, likely due to loss of volatile components. A 9% weight loss from 60-170°C which equates to 11.7 mols of water was observed. Melting points were not detected in the DTA traces, in keeping with amorphous behavior. Thermogravimetric analyses were carried out on a Mettler Toledo TGA / DSC1 STARe. The calibration standards were indium and tin. Samples were placed in an aluminum sample pan, inserted into the TG furnace and accurately weighed. Under a stream of nitrogen at a rate of 10°C / minute, the heat flow signal was stabilized for one minute at 30°C, prior to heating to 300°C.

[0275] Dynamic Vapor Sorption (DVS) can be utilized to assess 1-66 preparations. For example, the hygroscopicity and the sorption properties of an 1-66 preparation were determined using Dynamic Vapor Sorption (DVS). The sample exhibited continuous uptake of moisture, generating a steady increase in weight from 40-90% RH. The isothermal plot showed the total weight gain observed between ambient (40% RH) and 80% RH was 13.3% w / w, which indicated that the sample is hygroscopic, based on the European Pharmacopoeia classification. The rate of desorption was comparable with that of sorption, with little hysteresis. Post DVS XRPD analysis was carried out and the resulting XRPD pattern matched that of the supplied material, indicating that there were no apparent physical changes. Dynamic Vapor Sorption (DVS) was performed using a SMS DVS Intrinsic Vapor Sorption Balance. Approximately 30mg of sample was placed into an aluminum balance pan, loaded into the vapor sorption balance and held at 25°C + 0.1 °C. The sample was subjected to a 2-cycle step profile in 10% increments from 40-90-0-90-0-40%RH. The equilibrium criterion was set as cm / ct = 0.002% / min with a minimum of 60 minutes and a maximum of 5 hours for each increment. The weight change during the sorption cycle was monitored, allowing for the hygroscopic nature of the sample to be determined. The data collection interval was in seconds.

[0276] The specific optical rotation for a preparation of 1-66 was determined for 1-66 according to USP <781S> as [a]n25= -73.4° (c = 0.1% in 1% acetic acid / water).

[0277] Dissociation Constant and Isoelectric point. One pKa value for an 1-66 preparation wasmeasured at 5.0. Precipitation prevented determination of further pKa values. The calculated theoretical isoelectric point for 1-66 is 5.0.

[0278] Ultr violet- Visible Spectroscopy (UV-Vis). The ultraviolet and visible (UV-Vis) spectrum of I-66 at a concentration of 0.05 mg / mL (24 mM) showed absorbance peaks at about 200 nM and about 230 nM. At varying concentrations in methanol, absorbance maxima / relevant absorbances and corresponding molar absorptivities are listed below.

[0279] Table E-5. UV-Vis Spectrum Results for 1-66 in Methanol (190-800 nm).Path length: 1 mm

[0280] Solubility Profile: The solubility of 1-66 was estimated in 18 solvent systems using the aliquot addition method. These included 4 aqueous / organic mixtures. 1-66 had a solubility of >25mg / mL in 9 of the solvents and 3 of the aqueous mixtures at ambient temperature. Solubility data obtained are shown below as examples. Those experiments which did not show dissolution in ~40 volumes were temperature cycled for 2 cycles.

[0281] Table E-6. Solubility Estimates of 1-66 Free Acid at 20°C.

[0288] Peptide Content by Elemental Analysis.

[0289] The peptide content is determined by elemental analysis of the 1-66 drug substance using an elemental analyzer. Appropriate quantities of sample are introduced into the elemental analyzer, where it is converted to a gas by combustion at very high temperatures (e.g., 900 °C) in ultrapure oxygen. The nitrogen is converted to NOX, reduced to N2, separated in a GC column, and detected using a Thermal Conductivity Detector (TCD). The nitrogen content (%) is used to calculate the peptide content of the sample using the following formula: nitrogen content of the samplePeptide content = - x 100% theoretical nitrogen content

[0290] Where the theoretical nitrogen content is calculated based on the anhydrous, counterion free substance, i.e., 12.14%, based on the empirical formula for 1-66: C102H134N18O25S2 (free acid) MW 2076.42.

[0291] Potency Determination

[0292] When % peptide purity by RP-HPLC is 93.65 and % peptide content is 90.9, %assay = 85.1%.

[0293] In some embodiments, the present disclosure provides technologies for manufacturing 1-66 drug products. Certain preparations are described below as examples.

[0294] In some embodiments, an 1-66 drug product is supplied as a 10 mL liquid fill in Type 1 glassvials with appropriate elastomer stoppers, aluminum seals, and flip-cap. It is labeled for storage at refrigerated conditions (2- 8 °C). Supportive studies allow for drug administration by IV infusion to be performed at room temperature. 1-66 Injection contains 10 mg / mL 1-66, 10 mg / mL L-arginine, 33.6 mg / mL PEG-400, and 10 mM sodium phosphate adjusted to pH 8.0. An 1-66 drug product formulation is presented below as an example.

[0295] Table E-8. An 1-66 drug product formulation.

[0296] Various formulations were assessed in order to identify suitable formulations including for stability and solubility. In some embodiments, histidine, phosphate, or Tris buffers in the pH 6.5 to 8.0 range were assessed with Tris and phosphate at pH 7.5 or 8.0 being preferred. In some embodiments, tonicity modifiers sodium chloride or trehalose were assessed. In some embodiments, trehalose was selected based on achieved higher drug solubility. In some embodiments, various amino acid excipients were assessed. In some embodiments, glycine, proline, and arginine were evaluated. In some embodiments, arginine was selected based on higher drug solubility. In some embodiments, to improve solubility, e.g.. above about 10 mg / mL, addition of other excipients or cosolvents were assessed. For example, PEG-400, PEG-300, NMP, DMSO, and ethanol were evaluated. In some embodiments, PEG-400 and NMP provided higher solubility increases. In some embodiments, combining PEG-400 (e.g., about 3%) with arginine (e.g., about 10 mg / mL) in phosphate or tris buffer (e.g., about 10 mM) at a suitable pH, e.g., pH 7.5 or 8.0 was able to achieve stable concentrations of 1-66 above 25 mg / mL.

[0297] An admixture study was performed to establish the compatibility and stability of 1-66 Injection, 10 mg / mL when diluted with 5% Dextrose Injection, USP (D5W) in an IV admixture bag constructed of polyolefin with PVC ports. The dilution concentration was set at the worst case, lowest concentration of 0.24 mg / mL in the D5W bag. The admixture study demonstrated no incompatibilities, degradation, or loss of potency between the D5W solution with either the polyolefin bag or the PVC ports at this concentration. The admixture was shown to be stable for at least 24 hours under ambient room temperature conditions, showing no degradation or loss of potency over the studied time period.

[0298] 1-66 Injection, 10 mg / mL is manufactured by adding 1-66 Drug Substance to a solution of PEG-400 and L-arginine in sodium phosphate at pH 9.0 ± 0.2 in Water for Injection in the quantities described below. The pH is adjusted with IN hydrochloric acid to pH 8.0 ± 0.2 and diluted to the target 10 mg / mLconcentration with Water for Injection. The solution is then sterilized by duplicate 0.22 pm filtration and aseptically filled into sterile vials that are stopped and crimped with an aluminum flip-off seal.

[0300] The 1-66 drug substance stored in the freezer at -20 °C is moved to room temperature to warm before the dispensing. The dispensing of drug substance and all excipients is performed in a downflow booth. Compounding is performed in a Grade C suite. About 60% w / w WFI (13.2 kg ± 0.1 kg) is added to the single use 30 L formulation vessel containing a LevMixer stirrer. To the stirred WFI, PEG-400 (604.8 g ± 1%) is added, followed by L-arginine (180.0 g ± 1%) and sodium phosphate monobasic monohydrate (21.6 g ± 1%) at ambient temperature, and stirring for a minimum of 10 min. between each charge to ensure full dissolution. The pH of the solution is then adjusted to 9.0 ± 0.2 using either 1 N HC1 or 1 N NaOH as necessary. 1-66 drug substance (180.0 g, correcting for assay) is then charged to the formulation vessel using aliquots of the buffer solution to slurry the drug substance at ambient temperature and in portions. The stirred bulk mixture is pH adjusted to 8.0 ± 0.2 using IN HC1 or 1 N NaOH, at which point a clear solution is obtained. WFI is finally added to a final net weight of 18.2 ± 0.2 kg and the final formulation solution is mixed for NLT 15 min. The final pH of the mixture is measured. A sample is withdrawn for density, appearance, assay, and pre-filtration bioburden analysis.

[0301] In some embodiments, identification of the active pharmaceutical ingredient in the 1-66 drug product is performed by the assay and related substances RP-HPLC (Reverse Phase - High Performance Liquid Chromatography) method based on relative retention time.

[0302] Assay and Related Substances by HPLC.

[0303] In some embodiments, operating conditions for the identity, purity, and related substances method for 1-66 drug product, e.g., 1-66 Injection, 10 mg / niL, are provided below.

[0304] Table E-10. RP-HPLC instrument conditions for identity, purity, assay, and related substances determination for 1-66 drug product (e.g., 1-66 Injection, 10 mg / mL).

[0305] In some embodiments, assay by HPLC is about 90.0-110.0% of label claim. In some embodiments, 1-66 HPLC purity is about or at least about 94%, 95%, 96%, 97% or 98%. In some embodiments, pH is about 7.0-9.0.

[0306] In some embodiments, a drug substance or a drug product may contain one or more degradation products. In some embodiments, a drug product may contain higher levels of degradation products compared to a drug product. In some embodiments, based on the amino acid sequence of 1-66, anticipated degradation products may be related to degradation of the Asp2and Asp5residues as aspartate and asparagine are amino acids that commonly yield degradation products in peptides. Among other things, the present disclosure provides technologies for 1-66 drug substance and drug products that contain no detectable or low levels of degradation products and are suitable for clinical various clinical uses including those described herein.

[0307] Example 2. 1-66 is suitable for administration to human subjects for treatment of cancer.

[0308] Extensive studies of 1-66 support that it can be utilized for treating human patients. Certain studies are presented below as examples.

[0309] Primary pharmacology studies demonstrated high-affinity binding of 1-66 to 0-catenin, blockade of 0-catenin:TCF4 interactions in biochemical and cell-based assays, inhibition of WNT7 0-catenin downstream transcriptional programs in cancer cell lines and patient-derived xenograft (PDX) tumor models, and anti-tumor effect in PDX models carrying WNT-pathway activating mutations.

[0310] For example, in biochemical assays, direct binding of 1-66 to human beta-catenin protein was confirmed by X-ray crystallography. 1-66 binds directly to a previously unidentified binding site of beta-catenin that overlaps with the TCF binding site, within the beta-catenin armadillo repeat domain region of the protein. When tested by surface plasmon resonance (SPR), 1-66 binds with high affinity to beta-catenin with a dissociation constant (Kd) of 0.5 nM. Competition fluorescence polarization assays (CompFP) demonstrated 1-66 blocked beta-catenin:TCF4 interaction with an IC50 <5 nM.

[0311] In cell-based assays, intracellular target engagement was demonstrated by NanoBRET, TCF reporter, quantitative reverse transcription PCR (qPCR) assays, etc. 1-66 blocked the interaction ofbeta-catenin:TCF4 with an IC50 of 1.2 uM by a NanoBRET assay and inhibited TCF-driven transcriptional activity with an IC50 of 0.7 uM in a TCF luciferase reporter assay. 1-66 inhibited endogenous WNT / beta-catenin target gene expression with IC50S in sub or low uM in cancer cells. In proliferation assays, 1-66 displayed IC50 in sub or low uM in cancer cells that carry WPAMs.

[0312] In vivo target engagement was established using RNA sequencing (RNAseq) and protein western blot (WB) analyses. A single dose of 1-66 at 20-30 mg / kg significantly down-regulated the WNT / beta-catenin transcriptional pathway in xenograft tumors derived from colorectal cancer (CRC) cell line and CRC patient derived xenograft (PDX) models, which cany WNT pathway activating mutations. 1-66 treatment reduced the intratumoral expression of several WNT / beta-catenin target genes in a dose-dependent manner (i.e. CMYC, AXIN2) at both mRNA and protein levels in a CRC PDX model with WNT pathway activating mutations.

[0313] With repeat dosing on a once a week schedule at 20-60 mg / kg dose levels, 1-66 led to durable tumor regression or stasis in multiple CRC PDX models and one hepatocellular PDX model harboring WNT pathway activating mutations. No anti-tumor effects were observed in tested tumor xenograft models that do not carry known activating mutations of the WNT pathway. AXIN2 and C-MYC can both be relevant pharmacodynamic biomarkers since inhibition of these biomarkers is on-target, dose dependent, correlated with efficacy and in the case of C-MYC, without the intention to be bound by particular theory, likely to be relevant for the anti-tumor activity of 1-66 downstream of beta-catenin inhibition. Significant inhibition of AXIN2 and C-MYC is observed in tumors starting at 20 mg / kg and maximal inhibition is achieved at 60 mg / kg.

[0314] Many studies, including secondary pharmacology, safety pharmacology, pharmacokinetics, toxicology, etc., were performed, confirming that 1-66 can be administered as described herein for treating cancer.

[0315] Nonclinical pharmacology programs included an assessment of the potential of 1-66 to modulate binding and activity of many off-target receptors, enzymes, ion channels, and transporters. Safety pharmacology studies were conducted with animals including monkeys. PK of 1-66 was investigated in animals including BALB / c mice, Sprague Dawley rats, and cynomolgus monkeys to assess absorption, distribution, metabolism, and excretion. Both single- and multiple-dose intravenous (IV) administration were evaluated. In addition, in vitro metabolism studies were conducted with animals including rat, dog, monkey, and human liver microsomes and hepatocytes.

[0316] The toxicity profile of 1-66 was evaluated including in vitro in a bacterial reverse mutation assay and in a Chinese Hamster Ovary (CHO) cell micronucleus assay, and in vivo in Sprague Dawley rats and cynomolgus monkeys. In vivo studies included two non-GLP repeat-dose studies in rats (one with Q4D dosing and one with Q7D dosing), one non-GLP study in monkeys with an escalating dose phase and a repeat-dose phase, and two 5-week repeat-dose pivotal GLP compliant studies: one in rats and one in monkeys.

[0317] No modulation of ion channel current up to the highest concentration tested was observed. ECG tracings in monkeys did not show any test article related abnormalities in cardiac rhythm or conduction when Cmax values were many-fold high over the projected human Cmax value ranges.

[0318] Pharmacokinetic and toxicokinetic profiles confirmed 1-66 can be administered to human subjects for cancer treatment as described herein.

[0319] 1-66 exhibited high protein binding in human (2.1 to 4.1% unbound) and nonclinical species plasma, without concentration-dependent changes. 1-66 bound preferentially to human serum albumin in comparison to alphal-acid glycoprotein. 1-66 showed low partition to red blood cells across species.

[0320] 1-66 is stable for use as described herein. For example, 1-66 is stable in plasma, whole blood, and liver microsomes of at least BALB / c mice, SD rat, cynomolgus monkey and human. It is also stable in liver S9 fraction derived from rats and human. 1-66 was the predominant component following incubation in hepatocytes from mice, rats, monkeys and humans for up to 24 hours. There was no human unique metabolite in hepatocytes; rat and monkeys were deemed appropriate toxicology species based on the similarity of in vitro metabolism to human. 1-66 was also assessed for liver microsome. In some embodiments, drugs that are substrates of the relevant CYPs (1A2, 2B6, 2C8, 2C9, 2C19, 2D6, and 3A4) that have a narrow therapeutic index may not be co-administered with 1-66. In some embodiments, drugs that are MDR1 or BCRP substrates and have narrow therapeutic indices (e.g., digoxin and methotrexate) may not be co-administrated with 1-66. In some embodiments, caution should be exercised when co-administering medications that are substrates of OATP1B1 and OATP1B3 with 1-66. In some embodiments, medications that are substrates of OATP1B1 and OATP1B3 are not co-administered with 1-66.

[0321] 1-66 is not a substrate of the uptake solute carrier (SLC) transporters MATEl, MATE2-K, OAT1,OAT3, OCTI, OCT2 and OATP1B1, and is marginally a substrate of OATP1B3.

[0322] Toxicology of 1-66 was assessed in various assays including animals such as rat and monkey. Based on the results of the nonclinical toxicology programs, 1-66 has an acceptable safety profile for use as described herein.

[0323] Various safety pharmacology, toxicology, and toxicokinetics (TK) studies were conducted in accordance with guidelines issued by the ICH and GLP.

[0324] 1-66 has been compared to various other stapled peptide agents that can bind to beta-catenin in various assays including those described herein. In various cases, 1-66 demonstrated superior properties and activities, including higher potency for inhibiting beta-catenin : TCF interactions, modulating transcription, inhibiting cancer cell proliferation, etc.

[0325] Among other things, results described herein demonstrate an acceptable benefit / risk profile for administering 1-66 as an anticancer therapeutic for patients with known or suspected WPAM.

[0326] Example 3. Clinical dial designs to demonstrate safety and efficacy of 1-66.

[0327] Among other things, the present disclosure provides technologies including clinical trials for assessing and confirming safety and efficacy of 1-66. Useful examples are described below.

[0328] In some embodiments, 1-66 is assessed to confirm for treatment of advanced and / or metastatic solid tumors. 1-66 Injection, e.g., 10 mg / mL, is supplied as a sterile, aseptically processed solution labeled for storage at 2-8°C in single -use vials for intravenous (IV) administration. The initial dosing schedule is weekly (QW) in 28-day cycles and can continue until disease progression or the occurrence of unmanageable toxicity. A stud...
