Huntington's disease (HD) is a genetic disease associated with an abnormally long CAG repeat expansion in the huntingtin gene (HTT), which codes for the huntingtin protein (HTT). HTT genes that contain repeat lengths beyond a certain threshold produce mutant huntingtin protein (mHTT), which can induce pathological changes in the central nervous system. The risk, penetrance, and age of disease onset can be correlated with length of the HTT repeat expansion. Repeat counts of less than 27 CAG triads are associated with normal phenotype, while repeat counts from 27 to 35 generally confer normal phenotype but enhanced risk of disease in offspring. 36 to 39 repeats are associated with incomplete or reduced penetrance, with disease symptoms manifesting later in adult life, if at all. Repeat lengths greater than 40 confer full penetrance, while repeat counts of greater than 60 produce disease that can manifest as early as childhood.
The present disclosure relates to compounds useful for the detection or modulation of target nucleic acids, including DNA and RNA. The present disclosure further relates to methods for treatment of trinucleotide repeat disorders, which can include administration of oligonucleotide analogues that can bind pathogenic nucleotide repeats in DNA or RNA.

Biodistribution of compounds of the disclosure can be evaluated via methods that can directly or indirectly detect the presence of compound in tissue. For example, tissue of a subject administered a compound of the disclosure can be evaluated by mass spectroscopic methods, such as tandem mass spectrometry, whereby presence of compound in tissue samples can be evaluated on the basis of intensity of a signal corresponding to the mass of ionized compound or compound fragments. Other methods suitable for determination of biodistribution include administration of a radiolabeled analogue of the compound, and evaluation. of the radiographic signature of the analogue in the subject via imaging techniques such as autoradiography, positron emission tomography, or single-photon emission computed tomography.
In some embodiments, biodistribution of a radiolabeled analogue is evaluated via quantitative whole body autoradiography (QWBA). In quantitative whole body autoradiography, an animal subject is administered the radiolabeled analogue, euthanized at a specified timepoint subsequent to administration, frozen, and suspended in embedding media such as aqueous sodium carboxymethyl cellulose. The suspended carcass can be sectioned in a cryomacrotome, and the resulting sections can be mounted on an adhesive support and placed on an imaging plate sensitive to the specific radioisotope used in the radiolabeled analogue, such as carbon-14. The exposed imaging plates can then be converted to electronic form using a phosphor imager system, and selected areas of the image file can be electronically integrated to provide concentrations of analogue expressed in ng-equivalents of compound per gram of tissue (ng-eq/g).
The ONVBA assay can be repeated on multiple animal subjects, or selected parameters of the assay can be varied from animal to animal, such. as dosage, route of administration., or time from compound administration to euthanization. For example, a QW BA can comprise three components, where one animal is eutbanized four hours after administration of a radiolabeled analogue, a second animal is euthanized 12 hours after administration of the radiolabeled analogue, and a third animal is euthanized 7 days after administration of the radiolabeled analogue. Concentrations of the analogue in various tissues of each animal can then be determined and compared across each animal, thereby providing insight into the timecourse of biodistribution of the radiolabeled analogue and compound. In each study component, urine and feces of each subject animal can be collected and evaluated for radiolabeled analogue content.

This study was designed to determine the in vitro binding of Compound 1 to plasma proteins in C57BL6J mouse, Beagle dog, Göttingen minipig. sheep, Cynomolgus monkey, and human. Plasma Protein :Binding (PPB) was assessed in pooled male plasma at nominal. Compound 1 concentrations of 1, 10, and 50 μL. The assay was performed using the ultrafiltration technique and the concentrations of Compound 1 were determined by LC MS/MS analysis. Warfarin was used as positive control to validate each ultrafiltration run.
Using Busher's classification, Compound 1 binding to plasma proteins was ranked as high-to-very high (PPB>85.0%) at 1 μg/mL and high (85.0%≤PPB≤98.0%) at both 10 and 50 μg/mL. A slight concentration dependence was observed over the concentration range investigated, suggesting the tendency of PPB to become non-linear with increasing Compound 1 concentration. This trend was more evidently in mouse, dog, minipig, and human.
PPB results of Compound 1 at various concentrations are summarized in TABLE 1.
a Since Compound 1 concentration in the ultrafiltrate sample was less than the lower quantification limit (LLOQ = 50 ng/mL), the fraction unbound is calculated as F % < [LLOQ/(C0 · R)]*100, and PPB expressed as PPB % > 100 − F %; C0 is the Compound 1 initial concentration and R is the recovery
b SD not calculated since N ≤ 2
Male C57BL6J mouse, male Beagle dog, male Göttingen minipig, male sheep, male Cynomolgus Monkey, and male human plasma was purchased from BIOIVT (UK). Preclinical plasma. was pooled from at least 3 different non-fasted animals, whereas human plasma was obtained from at least 3 healthy and fasted volunteers.
K3EDTA was used as the anti-coagulant for both the species.
All plasma was stored at 20° C. and thawed only once on the day of the experiment. No pH correction was applied before the experiment.
In this study the binding of Compound 1 to mouse, dog, minipig, sheep, monkey, and human plasma proteins was determined in triplicate at the nominal concentrations of l, 10, and 50 using the ultrafiltration technique.
The separation of unbound Compound 1 from plasma proteins was performed using Centrifree ultrafiltration devices with a 30,000 regenerated cellulose membrane. 14101 The suitability of ultrafiltration as method for protein binding determination of Compound 1 was assessed.
Warfarin was used as a control compound at the single concentration of 4.1 uM in male human plasma (n=3) and the control was tested in parallel with the test item on each ultrafiltration run to confirm the correct experimental performance.
Phosphate buffered saline (PBS) was prepared at the concentration of 0.14 6M. The pH was measured and found to be 7.40. PBS was stored at 4° C.
The stock solution (SS) containing Compound 1 at 10 mg/mL, was prepared on. SS was further diluted in PBS supplemented with 0.2% (viv) formic acid to obtain the working solution WS1, 100 μg/mL. Compound 1 SS and Compound 1 WS were stored at −80° C.
A stock solution of warfarin (SS_W) was prepared in water: acetonitrile (50:50, v/v) at a nominal concentration of 3.24 mM (corresponding to 1 mg/mE). This solution was further diluted i.n the same solvent to obtain the working solution WS_W, 410 μM, which was used for plasma spiking.
Warfarin SS_W was stored at 4° C. (for not more than 21 days, as per method sheet). Warfarin WS_W was freshly prepared on each ultrafiltration occasion,
An appropriate volume of single aliquots of mouse, dog, minipig, sheep, monkey, and human plasma was spiked with SS 10 mg ML or WS 100 μg/mL. to obtain the target concentrations of 1, 10, and 50 μg/mL. Each sample was then mixed by gentle rocking and rotating for approximately 10-15 minutes prior to being transferred to ultrafiltration tubes.
The same procedure was performed for the preparation of warfarin control sample 4.1 μM (corresponding to 1265 ng/mL) in male human plasma.
To assess the suitability of the ultrafiltration technique, experiments to determine potential non-specific binding to the filter membrane and test item stability in plasma and PBS over the incubation time were conducted.
Assessment of Non-Specific Binding of Compound 1 to Ultrafiltration Equipment. 14191 An appropriate amount of PBS was spiked at three test item concentrations (1, 10, and 50 μg/mL). The samples were mixed for 1-2 min at room temperature.
Triplicate aliquots of each spiked sample were transferred into ultrafiltration tubes and spun at 1500 g in a Biolitge centrillwe with a fixed angle rotor at room temperature, until all loaded volume has passed through the filter.
Prior to centrifugation (to), triplicate aliquots from each sample were collected and Compound 1 concentrations (Co) were determined by LC-MS/NIS analysis. Mier centrifugation, triplicate aliquots of the bottom ultraidinile WO were retained and then analyzed by LC-MS/MS.
The stability of Compound 1. was assessed at two test item concentrations (1 and 50 μg/mL) in all plasma species and in PBS by incubating each matrix fur 15 min at 37° C. plus 4 hours at room temperature (time which covers incubation, ultrafiltration. and sample treatment for analysis). Compound 1. concentrations were determined by LC-MS/MS analysis at both to and t4h.
X4231 The in vitro binding of Compound 1 to plasma proteins was determined at the three concentrations 1, 10, and 50 μg/mL.
To prevent the non-specific binding of Compound 1 to the ultrafiltration tubes, the inner wall was rinsed with 10% (v/v) Triton X-100 solution and left to dry for at least 1 hour before use. 14251 Triplicate aliquots of each spiked plasma were transfured into ultrafiltration tubes. The ultrafiltration tubes were spun at room temperature for 20 min at 1500 g in a Biofuge centrifuge with a fixed angle rotor.
Prior to centrifugation, triplicate aliquots of spiked plasma were retained to give the concentration of Compound 1 in plasma (Co) post-ultracentrifugation. After centrilitgation, an appropriate aliquot of the top retentate (C,) and bottom ultrafiltrate (Cu) was then removed for LC-MS/MS analysis.
The whole ultrafiltration devices, the ultrafiltrate reservoirs and the filtrate cups were weighed before adding the sample, after adding the sample (only for the whole ultrafiltration devices) and at the end of the centrifugation. 14281 The same procedure was performed for warfarin control samples.
After collection, each ultrafiltration sample was checked for protein content to assess a possible protein contamination and then to confirm the filter integrity over ultrafiltration. The presence of proteins was assessed in the ultrafiltrate using the Bradford method. 14301 A calibration standard curve of bovine serum albumin was prepared at the ib lowing concentrations: 0, 50, 100, 200, 400, 600, 800, and 1000 μg/mL.
Calibration standard samples and ultrafiltrate samples were dispensed in a 96-well plate (6 μL/well) and supplemented with Coomassie Brilliant Blue G Solution (300 μl). After 1 min at room temperature, the absorbance of each well was measured at λ=595 nm by an absorbance microplate reader
Appropriate aliquots of spiked plasma (collected prior to and after ultrafiltration) and ultrafiltration samples (col.lected after ultrafiltration) were supplemented with an. equal. volume (matrix matching) of drug-free PBS or drug-free plasma, respectively.
After matrix matching, plasma and ultrafiltration samples were extracted and analysed by LC-MS/MS.
All samples were collected into uniquely identifiable containers, labelled with the study number, sample type, nominal sample concentration and incubation time. Compound 1 samples and Warthrin samples were stored at −80° C.
Non-Specific Binding (NSB)
NSB to ultrafiltration tubes was determined from the Compound 1 concentrations in PBS samples prior to centrifugation (C0) and in the collected ultrafiltration samples after centrifugation (Ca).
where:
C0=concentration of Compound 1 before the ultrafiltration, ng/mL
Cu concentration of Compound 1 after ultrafiltration, ng/mL
The extent of any potential loss o1 Compound 1 after incubation in plasma (or PBS) at room temperature as long as the duration of the experiment (t4a was calculated as follows:
Where:
C0 concentration in matrix (plasma or PBS) at to, ng/mL
C4h=concentration in matrix (plasma or PBS) after t4h, ng/mL
The binding or Compound 1 (B% or PPB%) to plasma proteins was determined using the following equations:
Where:
F=free fraction
R=recovery
The same calculations were performed for warfarin control sample.
Comparing the concentration of Compound 1 in the ultrafiltrate and in the retentate samples (after ultrafiltration) with that of Compound 1 in the samples before the ultrafiltration, a recovery value was obtained, as described in the following formula:
Where:
V0=initial volume of plasma sample, before ultrafiltration (mL)
V=volume of retenate, after ultrafiltration (mL)
Va=volume of ultrafiltrate, after ultrafiltration (mL)
C0=concentration t0 in to plasma sample (ng/mL)
Cr concentration in the retentate sample (ng/mL)
Cu=concentration in the ultrafiltrate sample (ng/mL)
The density of each matrix (plasma, retentate and ultrafiltration sample was assume 1.
The same calculations were performed for warfarin control sample.
NSB≤20% is acceptable. Compound 1 was considered stable in plasma and PBS lithe percentage difference between concentration after t4h and t0 is within ±15%. Protein binding of the positive control warfarin should be ≥98.0%. The protein concentration measured afterultrafiltration should be ≤0.3 mg/mL.
Recovery (R) values (Range of Recovery, %) were assessed as detailed as follows: R≥200 or R≤50 means Experimental data not valid; 50≤R<80 or 120<R≤200 means Experimental data potentially unreliable; and 80≤R≤120 means Experimental data valid.
Non-Specific Binding (NSB) Assessment.
On avenge, NSB to filter membrane represented 20.5%, 6.2%, and 2.2% at 1, 10, and 50 μg/mL Compound 1 concentrations, respectively, indicating an increase of NSB contribution with decreasing concentration (which is the typical trend for compounds showing NSB). Since the NSB was not greater than around 20% (in the worst-case scenario), the ultrafiltration technique was deemed fit for purpose.
The results of NSB assessment are presented in TABLE 2.
Compound 1 was stable (i.e., with a percentage loss not greater than 15%) in mouse, dog, sheep, monkey, and human plasma as well as PBS when incubated at room temperature for up to 4 hours at both 1 and 50 μg/mL.
Compound 1 was stable in minipig plasma at whereas a slight instability (characterized by a percentage loss of 22.5%) was observed at 50 μg/mL.
The results of Compound 1 stability in plasma and in PBS samples are presented in TABLE 3.
The extent of PPI3 has been defined according to Busher's classification: very high (PPB ≥98.0%), high (85.0%≤PPB≤98.0%), and medium-to-low (PPB <85.0%).
PPB results of Compound 1 at various concentrations (1, 10, and 50 μg/mL) are summarized in TABLE 1 and fully reported in TABLE 4.

b SD not calculated since N ≤ 2
No protein contamination was detected in any ultrafiltration Compound 1 samples.
The matrix-matched samples were analyzed using three qualified bioanalytical LC-ISS SIS methods: one for warfarin and two for Compound 1 (one for minipig and one for human, cynomolgus monkey, dog, sheep, and mouse
Carry over was assessed throughout the study phase by injection of one or more blank samples after a high concentration standard. Carry over was more than 25% of the response at the LLOQ for Compound 1 and less than 5% for the internal standard. Carry over was more than 25% of the response at the LLOQ for warfarin and less than 5% for the internal standard. Study samples were analyzed following the expected concentration to avoid potential impact on the final results.
Compound 1 and warfarin concentrations in study samples were determined from the appropriate calibration plots within BioLims.
Samples with unexpected results were re-assayed in duplicate. In some cases, results were not reportable (NR).
In agreement with Busher's classification, Compound 1 binding to plasma proteins was ranked as high-to-very high (PPB>85.0%) at 1 μg/,LL and high (85.0%≤PPB≤98.0%) at both 10 and 50 μg/mL. A slight concentration dependence was observed over the concentration range investigated, suggesting the tendency of PPB to become non-linear with increasing Compound 1 concentration. This trend was more evident in mouse, dog, minipig, and human.
The objective of this study was to assess tissue distribution, disposition, and pharmacokinetics (PK) of [14]-Compound 1 drug related material following a single intravenous (IV) administration to the male cynomolgus (Mama fascieutaris) monkeys at the target dose level of 5 mg/kg using quantitative whole-body autoradiography (QWBA). The cynomolgus monkey is representative of the distribution and excretion in a human. Three animals were placed into metabolism cages after dosing and kept up to 4, 12, and 168 h post dose, respectively.
Disposition of [14C]-Compound 1 was investigated in one animal only (No. 103, 1681. Total radioactivity was measured in urine, feces, and cage rinse.
Pharmacokinetic profiles were obtained in blood and plasma collected from each animal at selected timepoints post-dose up to the terminal timepoint. 14691 Following euthanasia at 4, 12, and 168 h post dose, tissue distribution of [14C]-Compound 1 was investigated using quantitative whole body autoradiography.
Following IV bolus administration of [14C]-Compound 1, very limited amounts of administered radioactivity (4,2% of the dose) were excreted over 168 h post-dose. This observation indicated that most of the dose was retained in the tissues: 1.5(and 1.7% of the dose was recovered in urine and feces, respectively. Cage rinse, which relates to urinary excretion, accounted for another 0.9% of the dose.
Total radioactivity in blood and plasma was quantifiable up to terminal timepoint in all animals. Over 168 h post dose (animal 103), systemic exposure to total radioactivity, measured as area under the plasma concentration time curve (AUC) from the start of dosing to the last quantifiable time point (Tlast) (AUC0-4), was 231000 and 205000 h·ng-eq/g in blood and plasma, respectively, while maximum concentration (Cmax) was 7510 ng-eq/g (C0 92.60 ng-eq/g) and 11500 ng-eq/g (C0 14000 ng-eq/g), respectively. Total radioactivity showed higher partitioning into plasma than blood (blood to plasma ratio 0.6-0.8) except for 168 h where a ratio of 2.1 was observed.
Clearance (CL) was 6.69 mL/h/kg (blood) and 14.0 mL/h/kg (plasma) and was significantly lower than were hepatic and renal blood flow rates (which are approximately 2616 and 1656 mL/h/kg). Consistently, mean volume of distribution at steady state (Vss), accounting for 2480 ml/kg (blood) and 2780 (plasma), was greater than total body water in cyrioniolgus monkey (which is approximately 693 mL/kg), indicating a moderate (0.6 to 5 L/kg) volume of distribution.
In general, [14C]-Compound 1 drug-related material was widely distributed throughout the whole body and quantifiable irl all tissues up to the last timepoint sampled. The distribution pattern in tissues was comparable between selected timepoints over 168 h post-dose. Very high concentrations were observed in .kidney cortex, joints (most likely connected to cartilage), and liver, suggesting potential accumulation in these tissues.
Other tissues that showed notable uptake were: salivary glands. bone surface. pancreas, hair follicles, large intestine mucosa, aortic wall, small intestine mucosa, adrenal gland, stomach mucosa, spleen, bone marrow, lymph nodes, and thymus.
Moderate brain penetration was observed (brain to blood ratio<1): total radioactivity distributed quite uniformly in relevant sub-regions (cerebelluni, olfactory bulb, thalamus, caudate putamen, cerebral cortex, and substantia mgra), but the highest concentrations were measured in the lateral ventricle, most likely in the choroid plexus.
Finally, radioactivity was also measured in tissues containing melanin (e.g., hair follicles and, most importantly, the uveal tract in the eye) indicating potential binding to melanin.

Minimum Acclimatization: At least 21 days (prior to Day 1)
Monkey was used as one of the non-rodent species required in toxicology studies by test guidelines. The cynomolgus monkey was chosen because the non-human primate blood brain barrier is more similar to that of a human than to a dog blood brain barrier.
Temperature and humidity were recorded daily during the study phases. Actual mean measurements (with ranges) were 21.3° C. and 52.7%. Average temperature and relative humidity were always within the acceptable ranges during the in life phase: 21-23° C. (20-24° C. for less than 24 hours acceptable) and 45-65% (40-70% for less than 24 hours acceptable), respectively.
Diet was offered ad libitum. throughout the study except for approximately 1 hour before and after dosing. A fruit, vegetable, and foraging mix supplement was also given.
Water, littered from normal domestic water, was offered ad libitum throughout the study.
Monkeys had access to specific environmental enrichment devices in each cage, Social interaction between animal and staff was ensured for an adequate time twice a day on working days, and once a day over the weekend.
Three naïve male Cynomolgus monkeys each received a single 1V bolus administration of [14C]-Compound 1 at a target dose of 5 mg/kg, Following dose administrafion, animals were placed into metabolic cages and the following matrices were collected as outlined in TABLE 6
Levels of total radioactivity were determined by liquid scintillation counting (LSC) in the following matrices: blood, plasma, urine, feces, and cage rinse.
At the terminal timepoin.t (4 h, 12 h, and 168 h post-dose, respectively), animals were euthanized, and the tissue distribution of total radioactivity was evaluated using QWBA.
Intra-organ distribution of total radioactivity was evaluated in brain (cerebellum, olfactory bulb, thalamus, caudate putamen, cerebral cortex, and substantia mgra), eye and kidney. Sections were collected using a cryomaerotome, freeze-dried, and exposed to imaging plates, The resulting electronic whole-body autoradiograms were evaluated for the quantitative assessment of radioactivity in the tissues.
Radioactivity data in blood, plasma and tissues were subject to non-compartmental analysis for evaluation of appropriate pharrnacokincAic parameters, where fimsible.
The stability of the test item was assessed, by measuring the radiochemical purity, under the following conditions prior to initiating in-vivo experimental activities.
An aliquot of the SS was heated at approximately 65° C. for 5 minutes to confirm that this step, during formulation preparation, would not affect 14C label stability.
The stability of the final formulation was assessed at room temperature for 4 and 24 hours.
A preliminary assessment of ([14C]-Compound 1 stability in monkey blood was also performed: a volume of monkey blank blood was spiked with an appropriate aliquot of radiolabeled SS and incubated at 37° C. for 4 and 24 hours.
As radioactivity could not be extracted using a standard approach, measurement of radiochemical purity after incubation in blood and assessment of stability in biological matrices were not possible.
The radioactivity concentration of the stock solution and dose formulation was determined as follows: three weighed aliquots were dispensed into glass vials, appropriately diluted with DPBS. Three weighed aliquots were then removed from each dilution, supplemented with liquid scintillant and radioassayed by LSC in order to determine the actual radioactive concentration and homogeneity of the solutions.
The dose formulation was administered intravenously, as a bolus, through the caudal vein.
Individual dose volumes were adjusted based on body weight of the animals on the day of dose administration. Doses were dispensed into pre-weighed syringes, which were weighed prior to and Miming dose administration. The actual. dose received by each animal was calculated from dose concentration, weight of dose administered and animal weight.
Following administration, urine and feces were collected quantitatively-at selected times post-dose and kept refrigerated, over wet ice, during collection.
On a daily basis and/or at the end of the collection period, metabolic cages were rinsed with ethanol/water (50:50, v/v) and the wash retained for quantitative determination of radioactivity.
Cage debris were collected and pooled by animal over the entire period of collection.
Following administration, systemic blood was removed from the cephalic vein, at each selected time point post-dose and transferred into tubes containing K/EDTA as anti-coagulant (actual times of bleeding were recorded).Following collection, all blood samples were thoroughly mixed and placed on. wet ice. Plasma samples were prepared within two hours of blood collection.
Triplicate aliquots of liquid samples (e.g., dose formulations, urine, plasma and cage wash) were counted directly in liquid scintillant.
Feces were homogenized in a suitable quantity of ultmpure water (approximate ratio 1:2, wfv) using Stomacher homogenizer. Weighed quadruplicate aliquots of homogenates (0.2-0.4 g) were solubilized by addition of 1 mL of Solvable tissue solubilizer, supplemented twice with 200 μL. of 30% hydrogen peroxide (H2O2) and incubated at approximately 50° C., until appropriate discoloration was achieved, prior to addition of scintillant.
Weighed triplicate aliquots of blood (100 μL.) were treated as fecal homogenates.
The remaining blood was centrifuged at 2000g for 10 min at approximately 4° C. within tsvo hours of col lection and the plasma decanted into plastic tubes. Aliquots of plasma were radio assayed by LSC. Blood pellets were discarded.
Radioactivity was determined in a Tricarb Series liquid scintillation analyzer. Quench correction was achieved during sample counting through the automatic assignment of a quench indicator (tSIE/AEC) value to the sample. This value was used to interpolate sample counting efficiency from an instrument stored quench curve generated from a series of sealed quenched standards. The interpolated efficiency value was used to automatically correct LSC data counts per minute (cpm) and obtain disintegrations per minute (dpm). A suitable scintillation fluid (Ultima Gold) was added to each sample prior to radio assaying by LSC for an appropriate time. Background counts were subtracted from quench corrected sample counts, According to the background value and count time, the limit of quantification was calculated.
At the last timepoint (4 h, 12 h, and 168 h post-dose, respectively) animals were euthanized and the tissue distribution of total radioactivity was evaluated using quantitative whole-body autoradiography.
Following euthanasia, animals were frozen by immersion into a freezing mixture of hexane/solid CO2. Animals were left in the freezing mixture for at least 2 hours, until completely frozen.
Frozen carcasses were embedded, left lateral side uppermost, in a block of sodium carboxymethylcellulose (approximately 2%, IA in water).
Each block was mounted in a CM3600 cryomacrotome (Leica Microsystems) maintained at approximately -20° C. After initial trimming of the block, sagittal whole body sections (40 p.m) were obtained at various levels through the carcass. Sections of interest mounted on pressure sensitive tape were left to dehydrate in the cryomacrotome Chamber at approximately -20° C. for approximately 60 h.
Freeze dried sections were placed against an image plate (IP), suitable for 14C, as long as 4 days. During the exposure period the IPs were placed in a copper-lead shielding box for minimizing external background signals. Following exposure, the IN were scanned by a laser beam, using a Fuji FLA5000 phosphor imager system, and the latent image captured and stored on an electronic data file.
For each set of whole body images obtained, the system was calibrated with biological standards of known radioactivity.
Selected tissues were identified on the image and integrated, using AIDA software, to give a value for tissue concentration. Triplicate measurements were made across each selected organ tissue, when possible, either by multiple integration. on a single section. or by multiple integration from a number of different sections.
Results generated from the integration were expressed as Bq/g and subsequently converted to ng-equivalents of Compound 1 g tissue (ng-ef/g), using dose formulation specific activity.
The limit of quantification (LOQ) for tissue distribution was set as 3 times the mean background levels of radioactivity (mean of seven measurements per IP).
For the purposes of quantification, the assumption was that all tissues analyzed had a similar density and quench characteristics to blood (used as calibration standards). Exceptions to this rule were bone and white fat, where correction factors of 0.48 and 0.84 were applied, respectively, to compensate for quenching of radioactivity.
A block of frozen CMC (approximately 2%, w/v, in water) containing standards of known radioactivity was prepared on a separate occasion. A series of paper straws were fixed in the block and monkey blood containing increasing amounts of a [14C]-Compound was dispensed into the straws and frozen. The range of calibration standards was chosen to cover the extent of likely tissue concentration values (actual range 56.8-32,274 Bq/g).
Calibration lines were generated for each set of sections exposed on a single IP by selecting an area of each standard from the scanned image and assigning the corresponding radioactivity concentration previously determined by LSC.
The radioactivity concentration and the radiochemical purity of the stock solution was checked prior to use. Radioactivity concentration (MBq/mL) was 9.52. Radiochemical purity was 93.2%.
Compound 1 was stable under the experimental conditions assessed.
Compound 1 Concentration: 2.33 mg/g (mg of Compound 1+[14C]-Compound 1)
Radioactivity Concentration: 2.52 MBq/g
Formulation Specific Activity: 1.08 MBq/mg
CV: 1.9% (overall pre- and post-dose)
Difference Pre vs Post dose: 1.6%
Radiochemical Purity: 91.8% (mean pre-and post-dose)
The formulations resulted to be homogeneous prior to and across dosing (CV<5%).
The difference between pre dose and post dose concentration was within ±10%.
The actual doses of [14C]-Compound 1 administered to male cynomolgus monkeys as single 1V bolus are presented in TABLE 7
aChemical dose concentration = 2.33 mg [14C]-Compound 1 + Compound 1/g of formulation

No clinical signs were observed following dosing.
Due to early terminal timepoints for animal 101 and 102, no excreta could be collected from these animals. Individual excretion data was obtained from animal 103 and is presented TABLE 8. Cumulative data of the: same animal i.s also presented in. TABLE 8. Cumulative excretion is also plotted in
Following IV bolus administration of MI-Compound 1, a very limited amount of administered radioactivity (4.2% of the dose) was excreted over 168 h post-dose, being most of the dose retained in the tissues: 1.5% and 1.7% of the dose was recovered in urine and feces, respectively. Another 0.9% of the dose was recovered in the cage rinse, which relates to urinary excretion.
Blood and Plasma Pharmacokinetics 15531 Individual concentrations of radioactivity in blood and plasma at various sampling times after a single IV bolus administration of [14C]-Compound 1 to male cynomolgus monkeys are presented in TABLE 9. Individual profiles of total radioactivity in blood and plasma are graphically shown in
PK parameters calculated from serial concentration time profiles of total radioactivity are presented in TABLE 10.
Total drug-related radioactivity in blood and plasma was quantifiable up to the terminal timepoint in all animals.
In animal 103 (168 h post dose), systemic exposure to total radioactivity, measured as AUC0-t, was 231000 and 20500 h·ng-eq/g in blood and plasma, respectively, while total radioactivity Cmax was 7510 ng-eq/g (C09260 ng-eq/g) and 11500 ng-eq/g (C014000 ng-eq/g), respectively.
CL was 6.69 ml/h/kg (blood) and 14.0 milli/kg (plasma) and was significantly lower than were hepatic and renal blood flow rates (Which are approximately 2616 and 1656 mL/h/kg). Consistently, mean Vss accounting for 2480 mL/kg (blood) and 2780 mL/kg (plasma) was significantly greater than was total body water in cynomolgus monkey (Which is approximately 693 mt/kg). This result indicated moderate (0.6 to 5 L/kg) distribution. Into tissues.
The elimination phase could not be defined because of very limited elimination over 168 h post-dose. Thus, acceptance criteria for terminal half-life T1/2 were not fully met and total radioactivity could not be reliably calculated: estimates of 229 and 141 h in blood and plasma, respectively.
Within 4 h of dosing (animal 101) a T1/2 of 1.85 h was evaluated in blood but indicated quick distribution rather than elimination.
Total radioactivity showed higher partitioning into plasma than blood (ratio 0.6-0.8) except for 168 h where a ratio of 2.1 was observed.
Concentrations of radioactivity in tissues and correspondent tissue to blood ratios (T/B) obtained Mowing single IV bolus administration of [14C]-Compound 1 to male cynomolgus monkeys at 5 mh/kg are presented in TABLE 11.

Tissue concentrations and T/B values are also graphically presented in
Within 4 hours of IV administration, radioactivity quickly and widely distributed in all tissues investigated, with the vast majority of tissues containing concentrations higher than in blood (1261 ng-eq/g).
The highest tissue concentrations at 4 hours post-dose were observed in the kidney cortex (125167 ng-eq/g, T/B 99.3), joints (likely connected with cartilage, 59612 ng-eq/g, TIB 47.3), and liver (34695 ng-eq/g, T113 27.5).
At this timepoint, several tissues showed a T/B>5: salivary glands (parotid TSB 14.2; others TSB 12,0), bone surface and pancreas (T/B 13.9), hair follicles (T/B 11,7), large intestine mucosa (T/B 9.8), aortic wall CUB 9.3), small intestine mucosa (1 B 8.3), adrenal cortex (I B 8.2), stomach mucosa (T′B 7.2), spleen (T/B 6.6), bone marrow (TIB 5.9), and lymph nodes (T/B 5.8).
At 12 h alter dosing, concentrations were generally comparable to those observed at the previous timepoint. At this timepoint, kidney cortex (145490 ng-eq/g, T/B 99.1), joints (130483 ng-eq/g, T/B 88.9), and liver (56919 ng-eq/g, T 38.8) were still the most exposed tissues and attained the highest concentration.
At this timepoint, several tissues showed aT/1-3? 5: salivary glands (parotid T/B 13.3: others T/B 9.1), pancreas (T/B 6.8), adrenal cortex and stomach mucosa (T/B 10.9), small intestine mucosa IT :B 10.5), hair follicles (T′B 10.3), lymph nodes (T/B 9.6), bone marrow (T/B 9.2), large intestine mucosa (T/B 8.9), aortic wall and spleen (LB 6.3), adrenal medulla (17B 5.3), and thymus (T/B 5.2), compared to a cardiac blood concentration of 1468 n.g-cq/g.
At 168 h post-dose, concentrations generally declined to concentrations comparable to that in blood (1642 ng-eq/g). The highest concentrations were observed in kidney cortex (103160 ng-eq'g, T/B 62.81, joints (47762 ng-eqfg, TiB 88.9), and liver (51575 ng-eq/g, T/B 31.4). The observations suggested potential accumulation in these tissues. Moreover, at this timepoint, other tissues showed notable distribution (5<T/B<3): adrenal gland, bone marrow, spleen, and lymph nodes.
[14C]-Compound 1 showed moderate brain penetration (T/B<1) and appeared to distribute uniformly throughout the tissue and in all sub-regions analyzed (cerebellum, olfactory bulb, thalamus, caudate putamen, cerebral cortex, and substantia mgra). The highest concentrations were measured in the lateral ventricle instead: 3763, 3781, 2868 ng-eq/g at 4, 12, and 168 h post-dose, respectively. This radioactivity was most likely connected to the choroid plexus within the ventricle.
[14C]-Compound 1 approximately equally partitioned between blood and uveal tract (cluroid+retinal pigmented epithelium) in the eye (2416 ng-eq: g (T/B 1.9), 2366 ng-eq g (T/B 1.6), 1286 ng-eq/g (1/B 0.8) at 4, 12, and 168 h post-dose, respectively). These observations indicated potential melanin binding. Consistently, high concentrations were also measured in the hair follicles.
Following IV bolus administration of [14C]-Compound 1 to male Cynomo gus monkeys only 4.2% of the administered dose was excreted over 168 h post-dose: 1.5% of the dose was recovered in urine and 1.7% in feces. Cage rinse, which relates to urinary excretion, accounted for another 0.9% of the dose.
Total drug-related radioactivity in blood and plasma was quantifiable up to the terminal timepoint in all animals.
Over 168 h post dose (Animal 103), systemic exposure to total radioactivity, measured as AUC0-t, was 231000 and 205000 h·ng-eq/g in blood and plasma, respectively, while total radioactivity was 7510 ng-eq/g (C0 9260 ng-eq/g) and 11500 ng-eq/g (C14000 ng-eq/g), respectively.
[14C]-Compound 1 showed moderate (0.6 to 5 L/kg) volume of distribution and low clearance, thus the elimination half-life T1/2, could not be reliably calculated. T1/2 estimates were 229 and 141 h in blood and plasma, respectively.
Total radioactivity tended to partition into plasma (blood to plasma ratio 0.6-0.8) except for 168 h, where a ratio of 2.1 was observed.
In general, [14C]-Compound 1 drug-related material was widely distributed throughout the whole body and quantifiable i.n. all tissues up to the last timepoint sampled. The distribution pattern in tissues was comparable between selected timepoints over 168 h post-dose. Very high concentrations were observed in kidney cortex, joints most likely connected to cartilage), and liver, suggesting potential accumulation in these tissues.
Other tissues that showed notable uptake were salivary glands, bone surface, pancreas, hair fbIlicles, large intestine mucosa, aortic wall, small intestine mucosa, adrenal gland, stomach mucosa, spleen, bone marrow, lymph nodes, and thymus. 15831 Moderate brain penetration was observed (brain to blood ratio<l): total radioactivity distributed quite uniformly in relevant sub-regions (cerebellum, olfactory bulb, thalamus, caudate putamen, cerebral cortex, and substantia mgra), but the highest concentrations were measured in the lateral ventricle, most likely in the choroid plexus.
Finally, radioactivity was also measured in tissues containing melanin (e.g., hair follicles and the uveal tract in the eye), indicating potential binding to melanin.

Plasma and tissue PK elaboration were performed by non-compartmental pharmacokinetics analysis using Phoenix WinNonlin, The following parameters for test item, when feasible, were determined using the linear logarithmic trapezoidal rule:
AUClast=area under the plasma concentration time curve (AUC) from the time of dosing to the last measurable concentration (expressed as ng·h/mL)
Cmax=maximum observed plasma concentration (expressed as ng/mL)
Tmax=time of maximum observed plasma concentration (expressed as hours)

This example demonstrates the ability of illustrative compounds of the disclosure to reduce selectively and potently expression of mutant Huntington's disease protein in cells without causing cytotoxicity.
A human subject-derived fibroblast cell line GM09197 was obtained from the Coriell Institute (Coriell Institute for Medical Research, Camden, NJ). The first huntingtin allele in this cell line is a mutant buntingtin allele with 151 CAG repeats (mHTT), which is associated with development of Huntington's disease. The second huntingtin allele in. this cell. line contains 21 CAG repeats. In some embodiments, this level can be considered a normal or wild type huntingtin allele (wtHTT) that is not considered to cause Huntington's disease. Cells were maintained at 37 *C and 5% CO2 in minimal essential media (MEM) supplemented with non-essential amino acids (Corning Inc, Corning N.Y., cat. n# 10-009-CV) and 10% heat inactivated FBS (Coming Inc,, Coming NJ cat. n# 35-016-CV).
Peptide nucleic acid (PNA) compounds of the disclosure were screened for toxicity and the ability to knockdown expression selectively of mHTT. Cells were plated in 24-well plates at 150,000 cells/well. In supplemented MEM one day before addition of PNA. Stock solutions of PNA were heated at 80° C. for 10 min before use and were added to final concentrations of 1 μM or 5 μM in the cell cultures. Cells were incubated for 3 days in the presence or absence of PNA compound before evaluation of huntingtin knockdown and cytotoxicity.
For huntingtin knockdown assays, cells were harvested with a trypsin-EDTA solution (0.25%, Invitrogen, Carlsbad, Calif., cat. n# 25200072) and lysed using M-Per buffer (Thermo Fischer Scientific, Waltham, Mass., cat. n# 78503). Total protein present in the lysates were quantified using BCA assay (Pierce BCA protein. Assay Kit cat. n# 23225, Thermo Fischer Scientific, Waltham, Mass.). mHTT and wtHTT proteins were separated by SDS-PAGE using 4-15% gradient gels (Rio-Rad Laboratories. Hercules, Calif., cat. n# 4561083) with Tris Glycine Running Buffer 0.1% SDS pH8.3 (Glycine cat. n# G8898, Sigma-Aldrich, St Louis Mo., Tri.-Base cat. n# BP1.52-500, Fisher Scientific, Hampton, N.H., SDS 10% solution cat. n# 1610416, Bio-Rad Laboratories, Hercules, Calif.). Gels were run at 165V for 2 hours. After gel electrophoresis, proteins were transferred to a nitrocellulose membrane (Bio-Rad Laboratories, Hercules, Calif., cat. n# 1620112).
A huntingtin-specilic primary antibody was used to bind specifically both mHTT and wtHTT (1:2500. Abeam, Cambridge UK, cat. nti ab109115), with a beta-actin-specific primary antibody as a control (1:5000, Abeam Cambridge, UK, eat. n4ab8227). Horseradish peroxidase (HRP) conjugated anti-mouse or anti-rabbit secondary antibodies (1:10,000, Jackson ImmunoResearch Laboratories, West Grove, Pa., cat. nil 315-035-0003 and 111-035-045) were used for visualizing proteins using SuperSignal West Pico Plus Chemilumineseent Substrate (Thermo Fischer Scientific, Waltham, Mass., cat. n# 34577). Protein bands were quantified using i Bright Analysis Software (Thermo Fischer Scientific, Waltham, Mass.). mUTT and wiFITT bands were normalized according to beta-actin expression, and mHTT and waITT expression inhibition was calculated as a relative value to untreated control cells.
These results demonstrate a structure-activity relationship between illustrative PNA compounds of the disclosure and potency and selectivity for modulating expression of target genes and proteins. As the PNA compounds evaluated comprise backbone modifications that alter their binding affinity for mHTT transcript, these results also show that modulating binding affinity via PNA backbone modifications can alter target selectivity and therapeutic potency.
To evaluate potential toxicity of the PNA compounds in the assay conditions, a Lactate Dehydrogenase (LDH) release cytotoxicity assay was performed using a CyQuant LDH kit (cat. n# C20300, Invitrogen, Carlsbad, Calif.).
For a maximum LDH release control, 10X Lysis Buffer was added to control wells comprising the GM09197 cells, and the plate was incubated at 37° C., 5% CO2 for 50 mm.
50 μL of medium from each sample and control well was transferred controls to designated wells in a 96-well fiat bottom plate. An LDH Positive Control from the kit was also used, as were basal medium LDH activity controls, with 50 μL. of culture medium±serum per basal LDH control well, and an untreated (PBS) control.
50 μL of Reaction Mixture was transferred to each sample and control well and mixed by gentle tapping. The plate was incubated at room temperature for 30 min protected from light, after which 50 gL of Stop Solution to was added to each well. Absorbance at 490 nm and 680 nm was measured. To determine LDH activity, the 680-nm absorbance value (background signal from instrument) was subtracted from the 490-nm absorbance value.
The percent of dead cells detected following treatment with the PNA compounds was not significantly different than that of untreated control. The result indicates that cytotoxicity was not observed for GM09197 cells treated with PNA compounds of the disclosure Compound 2 (
This example demonstrates that illustrative PNA compounds of the disclosure can be well tolerated when administered to subjects.
PNA compounds of the disclosure were administered to non-human primates intravenously via a single tail vein injection per animal. The single dose injections were well tolerated at doses of up to 5 mg/kg.
PNA compounds of the disclosure were administered via intraperitoneal injection into mice three times per week. Three times weekly doses of up to 2 mg/kg were well tolerated for up to five weeks.
