Technical Field The present disclosure relates to the fields of molecular biology and nucleic acid technology. The present disclosure also relates to therapy and prophylaxis of disease. 5 Background Gene therapy as a modality aims at ameliorating disease-related phenotypes by using both viral and non- viral delivery systems. Significant efforts have been focusing on optimizing this therapy to be more efficient, non-immunogenic and less toxic while enabling a long-term expression of the gene of interest.One of the key challenges to achieve this goal is to regulate the expression of the transgene to meet the 10 required level and to be expressed upon demand. For certain targets, where constitutive and unlimited expression leads to adverse events, regulated gene expression is necessary to render gene therapy a viable option as a treatment modality. One example is Rett Syndrome (RTT), an X-linked neurological disorder associated with severe motor abnormalities and 15 reduced lifespan that occurs in 1 in 1,000 females. RTT is characterized by seemingly normal neurological and physical development during early postnatal period followed by a rapid regression with the loss of the purposeful motor skills and the onset of repetitive and autistic behaviors'*. During the rapid progression stage, the child loses purposeful hand skills and spoken language, experiences motor impairments, and develops breathing abnormalities and may also develop autistic-like features and 20 seizures. At laterstages, further motor deterioration begins, typified by severe physical disability, which leads many patients to become dependent on the use of wheelchairs. Current treatment options are limited to symptom control. Mutations in the MECP2 gene on the X chromosome, encoding for methyl- CpG-binding protein 2 account for 95% of RTT cases*. MeCP2 is highly expressed in neurons and functions as a ubiquitous transcriptional regulator by binding to methylated DNA and recruiting protein 25 partners and regulatory complexes to control transcriptional activity. MeCP2 regulates neuronal physiology and maintenance and landmark studies have demonstrated that restoring levels of the MeCP2 protein dramatically reverses symptoms in mice*?. Given that it is a monogenetic disorder driven by the lack of MeCP2, a protein with multiple functions, 30 gene therapy is one potential avenue to treat RTT. Studies in RTT mice have provided encouraging data showing attenuated neurological dysfunctions as well asextended lifespan by intravenous administration of an Adeno-associated virus serotype 9 (AAV9) expressing the wild-type (WT) MeCP2 gene>*. Despite the promising potential of gene replacement therapy, high doses of MeCP2 by overexpression systems — which rely on the use of ubiquitous promoters resulting in uncontrolled level of the transgene — can lead 35 to toxicity with phenotypes similar to those observed in duplication syndrome, a condition mainly affecting males, characterized by moderate to severe intellectual impairment, and caused by a duplication of the MeCP2 gene on the X-chromosome®"°. The requirement of keeping MeCP2 expression level within a window for normal function is one of the most challenging aspects that has yet to be solved. One solution 1 WO 2024 / 251925 PCT / EP2024 / 065689 would be to develop controlled transgene expression systems in order to overcome this limitation and make gene therapy a viable treatment option. Inducible gene expression systems allow forreversibility and flexibility and enable the production of 5 therapeutics upon demand, thereby circumventing overdose-associated side effects. Such regulation can be achieved using small molecules, with which transgene expression can be induced (generating ON- switches) or repressed (OFF-switch). Among the existing inducible transcriptional gene regulatory systems, the tetracycline (Tet)-regulable system is the most widely exploited tool and can be used as an ON- or an OFF-switch. Tet-inducible systems, however, are derived from bacteria and require the 10 expression of the regulator protein, e.g. the ON-switch components include the tetracycline-controlled transactivator (tTA), which consists of the bacterial tetR with a C-terminal domain of VP16 (virion protein 16), derived from the herpes simplex virus. The required co-expression of these components further increase the limitations in the size of the transgene for AAV packaging, and can cause both silencing and potentialimmunogenicity effects when introduced into human tissue, which has hampered further 15 translation into the clinics’7. Another class of genetic switches originating from bacteria are riboswitches, RNA elements that are able to control gene expression in response to ligand binding, have a small genomic footprint and do not depend on other proteins for activity, which renders these types of regulated gene expression an attractive alternative to protein-based expression control systems'°. However, riboswitches suffer from a poor dynamic range as well as high basal activity’. 20 A new class of small molecules that regulate splicing of SMN2 exon 7 was recently identified, via screening using a reporter system based on the SMN2 transcript (described e.g. in WO 2009 / 151546 A2). SMN2 reporter systems have since been proposed to be used as gene expression switches, where expression of a transgene is regulated through small molecule-controlled splicing of the expression 25 cassette (Monteys efal. Nature (2021) 596: 291-295). Known human SMN2 exon 6 to exon 8-derived transgene expression systems are described e.g. in Zhang, ef al., Gene Ther. (2001) 8: 1532-1538, WO 2022 / 204471 A1, Monteys ef a / . Nature (2021) 596: 291-295 and WO 2021 / 163556 A1. However, these known SMNZ2-based switch systems have very long nucleotide sequences, limiting the 30 __ size of the transgene that can be employed under the control of the system. That is, the size of an insert comprising the switch and the coding sequence for a therapeutic polypeptide to be delivered as gene therapy would very often be much larger than the packaging limit for vectors routinely employed in the delivery of gene therapies, e.g. adeno-associated viral (AAV) vectors. 35 Summary In a first aspect, the present disclosure provides a polynucleotide comprising in 5’ to 3’ order: (i) a first nucleotide sequence, comprising a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ IDNO:222, wherein the first nucleotide sequence does not comprise SEQ ID NO:2; 40 (ii) a second nucleotide sequence, comprising a nucleotide sequence having at least 80% sequence identity to SEQ ID NO:7 at its 5’ end, and comprising a nucleotide sequence having at least 2 WO 2024 / 251925 PCT / EP2024 / 065689 80% sequence identity to a nucleotide sequence according to SEQ ID NO:378 at its 3’ end, and consisting of fewer than 1044 nucleotides; (iii) a third nucleotide sequence consisting of a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:226; 5 (iv) a fourth nucleotide sequence, comprising a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:15 at its 5’ end, and comprising a nucleotide sequence having at least 80% sequence identity to SEQ ID NO:16 at its 3’ end; (v) a fifth nucleotide sequence: (a) consisting of the dinucleotide ‘GA’, ‘TG’ or ‘TT’, or (b) comprising a nucleotidesequence having at least 80% sequence identity to a nucleotide sequence 10 according to SEQ ID NO:19, wherein the nucleotide sequence comprises ‘GA’, ‘TG’ or ‘TT’ at the positions corresponding to positions 1 and 2 of SEQ ID NO:19, or (c) encoding a polypeptide of interest, and comprising ‘GA’, ‘TG’ or ‘TT’ at positions 1 and 2; and (vi) where the fifth nucleotide sequence is a nucleotide sequence according to (v)(a) or (v)(b), a sixth nucleotide sequence encoding a polypeptide of interest; 15 wherein the polynucleotide comprises a start codon 35’ to the nucleotide sequence encoding a polypeptide of interest.

Interaction of the small molecules with the mRNA-protein complex is thought to be critical for the high selectivityof the compound. This study suggested that both ESE2 and 5'ss regions are required for full activity of the SMSM compounds in a dose-dependent manner". Structural analysis using a compound from the same 30 chemical class as risdiplam (SMN-C5) has demonstrated that the drug selectively promotes the recognition of the weak 5’ splice site of SMN2 exon 7 by U1 snRNP by stabilizing an unpaired adenine at the exon-intron junction in the RNA helix’®. The present disclosure provides novel S / MMN / 2 exon 6 to exon 8-derived constructs providing for the 35 SMSM-inducible regulation of transgene expression, which are suitable to be employed for chemically- inducible regulation of the expression of gene therapies. In particular, the present disclosure provides ON-switch constructs: (i) having a size permitting their application for the SMSM-inducible expression of polypeptides to be delivered as gene therapies, (ii) 40 minimising undesirable expression of the polypeptide in the absence of the SMSM,and (ili) which are highly responsive to the SMSM, thus providing for strong induction of expression of the polypeptide in the presence of the SMSM, and (iv) that minimise the number of / completely remove extraneous amino acids 6 WO 2024 / 251925 PCT / EP2024 / 065689 at the N-terminus of the expressed polypeptide.

Such molecules are reviewed e.g. in Tang ef ai., Molecules (2021) 26(8):2263 and Schneider-Poetsch ef a / ., The Journal ofAntibiotics (2021) 74:603-616, both of which are hereby incorporated by reference in their entirety. Splicing modifiers generally reduce / prevent association of factors required for normal post-transcriptional 35 processing (e.g. components of the spliceosome) with RNA. Splicing modifiers typically bind to a nucleotide sequence of a polyribonucleotide and either inhibit or promote the association of RNA-binding proteins and / or non-coding RNAs which function as splicing activators or repressors. Through competitive inhibition of the recruitment of splicing activators and splicing repressors to the polyribonucleotide, splicing modifiers can alter the equilibrium of the splicing-regulatory RNA structures, and thus promote an 40 increase or decrease in skipping or inclusion of an exon and / or retention or excision of an intron in the mature RNA molecule produced by splicing. 44 WO 2024 / 251925 PCT / EP2024 / 065689 In some embodiments, a splicing modifier is a small molecule or a splice-switchingnucleic acid (e.g. a splice-switching oligonucleotide). A ‘small molecule’ refers to a low molecular weight (<1000 daltons, typically about 300 to about 700 5 daltons) organic compound. Splice-switching nucleic acids are reviewed e.g. in Haves and Hastings, Nucleic Acids Res. (2016) 44(14): 6549-6563, which is hereby incorporated by reference in its entirety. Splice-switching nucleic acids include e.g. splice-switching oligonucleotides (SSOs). They disrupt the normal splicing of target 10 RNA transcripts by blocking the RNA:RNA base-pairing and / or protein:RNA binding interactions that occur between components of the splicing machinery and pre-mRNA. Splice-switching nucleic acids may be designed to target a specific region of the target transcript, e.g. to promote skipping of exon(s) of interest and / or to promote inclusion of exon(s) of interest and / or to promote retention of introns of interest and / or to promote excision of introns of interest. SSOs often comprise alterations tooligonucleotide 15 sugar-phosphate backbones in order to reduce / prevent RNAseh degradation, such as e.g. phosphorothioate linkages, phosphorodiamidate linkages such as phosphorodiamidate morpholino (PMQs), and may comprise e.g. peptide nucleic acids (PNAs), locked nucleic acids (LNAs), methoxyethyl nucleotide modifications, e.g. 2’'0-methyl (2’OMe) and 2'-O-methoxyethyl (MOE) ribose modifications and / or 5’-methylcytosine modifications. 20 Small molecule splicing modifiers contemplated in accordance with the present disclosure include RG- 7800 and RG-7916 (also known as risdiplam), and analogs thereof. RG-7800 and RG-7916 bind to the 5’ splice site of intron 7 and exonic splicing enhancer 2 of exon 7 of human SMN2, thereby stabilising the transient double-strand RNA structure formed by the SMN2 pre-mRNA and U1 snRNP complex, and 25 promoting inclusion of exon 7 in the mature RNA molecule obtained following splicing of pre-mRNA transcribed from SMN2. RG-7800 and RG-7916 are useful torestore functional SMN2 protein expression from SMN2 alleles comprising the spinal muscular atrophy (SMA)-associated polymorphism c.840C>T (which potentiates skipping of exon 7). RG-7916 (DrugBank Acc. No. DB15305) is a close structural analog of RG-7800 having improved potency, pharmacokinetics and safety profile than RG-7800, and is 30 approved by the FDA for the treatment of SMA. Further analogs of RG-7800 and RG-7916 having similar splicing modifier activity include SMN-C2, SMN-C3, SMN-C5 and TEC-1. Branaplam (DrugBank Acc. No. DB14918; also known as LMI-070) is another small molecule splicing modifier that promotes inclusion of exon 7 in the mature RNA expressed from SMN2. Like RG-7800 and 35 RG-7916, branaplam binds to the 5’ splice site of intron 7 of human SMNZ2. PK4C9 (also known as homocarbonyltopsentin) is another small molecule splicing modifier that promotes inclusion of exon 7 in the mature RNA expressed from SMINZ. It is thought to bind to the 5’ splice site of exon 7and TSL2, and improve accessibility of the 5’ splice site via stabilising a triloop structure of TSL2. 40 Small molecule splicing modifiers that promote inclusion of exon 7 in the mature RNA expressed from SMN2 are described e.g. in WO 2015 / 173181 A1 and WO 2009 / 151546 A2, which are hereby 45 WO 2024 / 251925 PCT / EP2024 / 065689 incorporated by reference in their entirety. Further small molecule splicing modifiers that promote inclusion of exon 7 in the mature RNA expressed from SMN2 are described e.g. in WO 2022 / 204471 A1, which is hereby incorporated by reference in its entirety. 5 Nusinersen (DrugBank Acc. No. DB13161) is a splice-switching oligonucleotide that promotes exon 7 retention in mature RNA expressed from human S / MN2. Nusinersen is an 18-mer 2’°-MOe phosphorothioate antisense oligonucleotide that hybridises to intronic splicing silencer site 1 of intron 7, occupying the site and thereby inhibiting the association of the splicing suppressor ribonucleoproteins hnRNPs A1 / A2, thuspromoting inclusion of exon 7 in the mature RNA molecule. 10 The splicing modifier according to the present disclosure preferably promotes inclusion of SMN2 exon 7 in RNA obtained following splicing of pre-mRNA transcribed from human SMN2. Such molecules increase the proportion of RNA molecules comprising SMN2 exon 7 among RNA molecules obtained following splicing of pre-mRNA transcribed from human SMN2 (ie. relative to the proportion obtained in the 15 absence of the splicing modifier). For conciseness, ‘a splicing modifier that promotes inclusion of SMN2 exon 7 in RNA obtained following splicing of pre-mRNA transcribed from human SMN2’ may be referred to herein simply as ‘a splicing modifier that promotes SMN2 exon 7 inclusion’ In some embodiments, the splicing modifier promotes inclusion of exon 7 in RNA obtained following 20 splicing of pre-mRNA transcribed from an allele of human SMN2 comprising c.840C>T. That is, in some embodiments, the splicing modifier increases the proportionof RNA molecules comprising SMN2 exon 7 among RNA molecules obtained following splicing of pre-mRNA transcribed from an allele of human SMN2 comprising c.840C>T (i.e. relative to the proportion obtained in the absence of the splicing modifier). 25 In some embodiments, the splicing modifier increases the level of human SMN2 protein comprising amino acids encoded by exon 7 of human SMA2 (i.e. relative to the level detected in the absence of the splicing modifier). In some embodiments, the splicing modifier increases the proportion of polypeptides comprising amino acids encoded by exon 7 of human SMN2 among polypeptides expressed from human 30 SMN2 (i.e. relative to the proportion obtained in the absence of the splicing modifier). In some embodiments, the splicing modifier increases the proportion of polypeptides comprising amino acids encoded by exon 7 of human SMA / 2 among polypeptides expressed from an allele of human SMN2 comprising c.840C>T (i.e. relative to the proportion obtained inthe absence of the splicing modifier). 35 In some embodiments, the splicing modifier promotes inclusion of the third nucleotide sequence in the product of splicing of a polynucleotide according to the present disclosure (i.e. where the polynucleotide is a polyribonucleotide). In some embodiments, the splicing modifier increases the proportion of molecules comprising the third nucleotide sequence among molecules obtained following splicing of a polynucleotide according to the present disclosure (i.e. where the polynucleotide is a polyribonucleotide). 40 In some embodiments, the splicing modifier promotes inclusion of the nucleotide sequence consisting of SEQ ID NO:13 in molecules obtained following splicing of a polyribonucleotide consisting of the sequence 46 WO 2024 / 251925 PCT / EP2024 / 065689 of SEQ ID NO:22. In some embodiments, the splicing modifier increases the proportion of molecules comprising the nucleotide sequence consisting of SEQ ID NO:13 among molecules obtained followingsplicing of a polyribonucleotide consisting of the sequence of SEQ ID NO:22. 5 In some embodiments, the splicing modifier promotes inclusion of the nucleotide sequence consisting of SEQ ID NO:13 in molecules obtained following splicing of a polyribonucleotide consisting of the sequence of SEQ ID NO:23.

In some embodiments, the splicing modifier increases the proportion of molecules comprising the nucleotide sequence consisting of SEQ ID NO:14 among molecules obtained following 15 splicing of a polyribonucleotideconsisting of the sequence of SEQ ID NO:24. In some embodiments, the splicing modifier promotes inclusion of the nucleotide sequence consisting of SEQ ID NO:13 in molecules obtained following splicing of a polyribonucleotide consisting of the sequence of SEQ ID NO:25. In some embodiments, the splicing modifier increases the proportion of molecules 20 comprising the nucleotide sequence consisting of SEQ ID NO:13 among molecules obtained following splicing of a polyribonucleotide consisting of the sequence of SEQ ID NO:25. In some embodiments, the splicing modifier promotes inclusion of the nucleotide sequence consisting of SEQ ID NO:13 in molecules obtained following splicing of a polyribonucleotide consisting of the sequence 25 of SEQ ID NO:28. In some embodiments, the splicing modifier increases the proportion of molecules comprising the nucleotide sequence consisting of SEQ ID NO:13 among molecules obtained following splicing of a polyribonucleotide consisting of the sequence of SEQID NO:28. In some embodiments, the splicing modifier promotes inclusion of the nucleotide sequence consisting of 30 SEQ ID NO:27 in molecules obtained following splicing of a polyribonucleotide consisting of the sequence of SEQ ID NO:29. In some embodiments, the splicing modifier increases the proportion of molecules comprising the nucleotide sequence consisting of SEQ ID NO:27 among molecules obtained following splicing of a polyribonucleotide consisting of the sequence of SEQ ID NO:29. 35 Splicing modifiers having such functional properties can be identified by analysis e.g. in suitable in vitro assays. Such assays may comprise culturing cells in vitro in the presence or absence of a candidate splicing modifier, and analysing the RNA and / or protein produced after an appropriate period of time for an effect of the candidate splicing modifier to be observed. By way of illustration, cells can be transfected with a vector comprising DNA having the sequence of SEQ ID NO:22 and cultured inthe presence or 40 absence of a candidate splicing modifier for a suitable period of time (e.g. 24, 48, 72 hours). RNA can subsequently be isolated from the cells, and analysed (e.g. by (RT-PCR) to determine the 47 WO 2024 / 251925 PCT / EP2024 / 065689 level / proportion of mature RNA molecules comprising the nucleotide sequence consisting of SEQ ID NO:13. In some embodiments, a splicing modifier that promotes SMN2 exon 7 inclusion according to the present 5 disclosure is a compound of formula (I) of WO 2015 / 173181 A1. In some embodiments, a splicing modifier that promotes SMNV2 exon 7 inclusion according to the present disclosure is a compound selected from those listed in claim 39 of WO 2015 / 173181 A1. In same embodiments, a splicing modifier that promotes SMN2 exon 7 inclusion according to the present disclosure is a compound selected from those listed in claim 40 of WO 2015 / 173181 A1. 10 In some embodiments, the splicing modifier according to the present disclosure is selected from: RG-7916, RG-7800, SMN-C2, SMN-C3, SMN-C5, TEC-1, branaplam, PK4C9 and nusinersen.

In 15 preferred embodiments, the splicing modifier is risdiplam (RG-7916). Functional properties of the polynucleotides In aspects and embodiments of the present disclosure, the polynucleotides of the present disclosure may be characterised by reference to one or more functional properties. 20 In some embodiments, where the polynucleotide is a polyribonucleotide, splicing of the polyribonucleotide in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion yields polyribonucleotides substantially lacking the third nucleotide sequence. In some embodiments, where the polynucleotide is a polyribonucleotide, splicing of the polyribonucleotide in the presence of a splicing modifier that promotes 25 SMN2 exon7 inclusion yields polyribonucleotides comprising the third nucleotide sequence. In some embodiments, in the presence of a splicing modifier that promotes SMAN / 2 exon 7 inclusion, inclusion of the third nucleotide sequence is promoted in splicing of the polyribonucleotide, favouring the production of mature RNA molecules encoding the polypeptide of interest, and thus expression of the 30 polypeptide of interest at the protein level. Such polynucleotides may be referred to herein as ‘ON-switch’ polynucleotides. In some embodiments, cells comprising an ON-switch polynucleotide of the present disclosure substantially do not express the polypeptide of interest in the absence of a splicing modifier that promotes 35 SMN2 exon 7 inclusion. In some embodiments, cells comprising the ON-switch polynucleotide express the polypeptide of interest in the presence of a splicing modifier that promotes SMN2 exon 7 inclusion. Exemplary ON-switch polynucleotides according to the present disclosureinclude polynucleotides comprising SEQ ID NO:22, 23, 24 or 25. Further exemplary ON-switch polynucleotides according to the 40 present disclosure include polynucleotides comprising one of SEQ ID NOs:37 to 105. 48 WO 2024 / 251925 PCT / EP2024 / 065689 Inclusion of the third nucleotide sequence as described herein in the products of splicing of a polyribonucleotide according to the present disclosure can be evaluated using methods that are well known to the person skilled in the art. Such methods include qRT-PCR based methods for the detection and / or quantification of RNA molecules comprising nucleotide sequences of interest. 5 For example, cells may be transduced in vitro with a vector comprising a polynucleotide according to the present disclosure and subsequently cultured in vitro in the presence or absence of a splicing modifier that promotes SMN2 exon 7 inclusion for a period of time appropriate for an effect on splicing cf a polyribonucleotide according to the present disclosure to beobserved. After such period of time, total 10 RNA may be isolated from the cells, cDNA may be prepared from the total RNA, and the number / proportion of mature RNA molecules comprising the third nucleotide sequence may be evaluated by qPCR using oligonucleotides providing for the specific amplification and / or detection of the products of splicing of the polyribonucleotide (e.g. oligonucleotides hybridising to nucleotide sequences spanning exon:exon boundaries). The qPCR analysis may employ oligonucleotides enabling distinction between 15 RNA molecules comprising the third nucleotide sequence, and RNA molecules lacking the third nucleotide sequence. Such gRT-PCR-based methods for analysing the products of splicing of a polyribonucleotide are described in the experimental examples of the present disclosure. Expression of a polypeptide of interest can be evaluated using any suitable technique for the detection 20 and / or quantification of the relevant polypeptide. Such techniques includee.g. antibody-based methods, (for example flow cytometry, immunocytochemistry, western blot, ELISA), fluorescence microscopy and flow cytometry. In some embodiments, expression of a polypeptide of interest can be evaluated as described in the experimental examples of the present disclosure. In preferred embodiments, expression of a polypeptide of interest may be evaluated by flow cytometry. 25 Herein, within a plurality / population of polyribonucleotides obtained after splicing that ‘substantially lack’ the third nucleotide sequence, the third nucleotide sequence may be present in fewer than 15%, e.g. one of $10%, <5%, $4%, $3%, $2% or $1% of the polyribonucleotides. Conversely, within a plurality / population of polyribonucleotides obtained after splicing that ‘comprise’ the third nucleotide 30 sequence, the third nucleotide sequence may be present in more than 80%, e.g. one of 285%, 290%, 291%, 292%, 293%, 294%, 295%, 296%, 297%, 298%, 299% or 100% of the polyribonuclectides. Herein,within a plurality / population of cells that ‘substantially do not express’ a polypeptide of interest, the polypeptide may be expressed by fewer than 15%, é.g. one of $10%, 5%, 34%, $3%, $2% or s1% of the 35 cells. Conversely, within a plurality / population of cells that ‘express’ a polypeptide of interest, the polypeptide may be expressed by more than 80%, e.g. one of 285%, 290%, 291%, 292%, 293%, 294%, 295%, 296%, 297%, 298%, 299% or 100% of the cells.

In some 49 WO 2024 / 251925 PCT / EP2024 / 065689 embodiments, cells that ‘express’ a polypeptide of interest may display a level of expressionof the polypeptide of interest which is greater than 5 times, e.g. one of 210 times, 220 times, 250 times, 2100 times, 21000 times, 25000 times or 210000 times level of expression by cells that ‘substantially do not express’ the polypeptide of interest. 5 In some embodiments, the level of RNA comprising a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 in cells comprising a polynucleotide according to the present disclosure following culture in the presence of a splicing modifier that promotes SMN2 exon 7 inclusion is greater than 1 times, e.g. one of 22 times, 23 times, 24 times, 25 times, 210 10 times, 220 times, 250 times, 2100 times, 21000 times, 25000 times or 210000 times the level in equivalent cells cultured in the absence of the splicing modifier that promotes SMN2 exon 7 inclusion. In some embodiments, the level of RNA comprising a nucleotide sequence having at least 80% sequence identity to a nucleotide sequenceaccording to SEQ ID NO:11 in cells comprising a polynuclectide 15 according to the present disclosure following culture in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion is less than 100 times, e.g. one of $50 times, $20 times, $10 times, <5 times, $4 times, <3 times, <2 times or <1 times the level of RNA comprising a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 in equivalent cells not comprising the polynucleotide. 20 In some embodiments, the level of a polypeptide of interest in cells comprising a polynucleotide according to the present disclosure (e.g. an ON-switch polynucleotide) in the presence of a splicing modifier that promotes SMN2 exon 7 inclusion is greater than 1 times, e.g. one of 22 times, 23 times, 24 times, 25 times, 210 times, 220 times, 250 times, 2100 times, 21000 times, 25000 times or =10000 times the level 25 in equivalent cells cultured in the absence of the splicing modifierthat promotes SMN2 exon 7 inclusion.

Such polynucleotides may be referred to herein as ‘OFF- switch’ polynucleotides. 10 In some embodiments, cells comprising an OFF-switch polynucleotide of the present disclosure express the polypeptide of interest in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion. In some embodiments, cells comprising the OFF-switch polynucleotide do not express the polypeptide of interest in the presence of a splicing modifier that promotes SMN2 exon 7 inclusion. 15 Exemplary OFF-switch polynucleotides according to the present disclosure include polynucleotides comprising SEQ ID NO:28 or 29. In some embodiments, the level of RNA comprising a nucleotide sequence having at least 80% sequence 20 identity to a nucleotide sequence according to SEQ ID NO:26 in cells comprising a polynuclectide according to the present disclosure following culture in the presence of a splicingmodifier that promotes SMN2 exon 7 inclusion is greater than 1 times, e.g. one of 22 times, 23 times, 24 times, 25 times, =10 times, 220 times, 250 times, 2100 times, 21000 times, 25000 times or 210000 times the level in equivalent cells cultured in the absence of the splicing modifier that promotes SMN2 exon 7 inclusion. 25 In some embodiments, the level of RNA comprising a nucleotide sequence having at least 80% Sequence identity to a nucleotide sequence according to SEQ ID NO:26 in cells comprising a polynuclectide according to the present disclosure following culture in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion is less than 100 times, e.g. one of <50 times, <20 times, <10 times, <5 times, <4 30 __—ittimes, $3 times, <2 times or <1 times the level of the polypeptide of interest in equivalent cells not comprising the polynucleotide.

The polynucleotides of the present disclosure possess novel and / or improved properties relative to known transgene expression systems, e.g. known transgene expression systems comprising a SMSM-mediated 20 switch derived from SMN2 exons 6 to 8 (e.g. SMN2Z exon 6 to exon &-derived transgene expression systems described in Zhang, ef a / ., Gene Ther. (2001) 8: 1532-1538, WO 2022 / 204471 A1, Monteys et al. Nature (2021) 596: 291-295 or WO 2021 / 163556 A1). In some embodiments, the polynucleotides of the present disclosure possess novel and / or improved 25 properties relative to a SMN2ind minigene polynucleotide (which is defined hereinabove). In some embodiments, cells comprising a polynucleotide of the present disclosure cultured in the presence of a splicing modifier that promotes SMN2 exon 7 inclusion produce a population of RNA molecules having an increased proportion of RNAmolecules comprising a nucleotide sequence having at 30 least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or 26, compared to the population of RNA molecules produced by cells comprising a SMN2ind minigene polynucleotide and cultured under the same conditions. That is, in some embodiments the polynucleotide of the present disclosure is more effective at promoting inclusion of a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or 26 in the presence of a 35 splicing modifier that promotes SMN2 exon 7 inclusion, compared to a SMN2ind minigene polynucleotide. That is, the polynucleotides of the present disclosure are more responsive to induction of SMN / 2 exon 7 variant inclusion in the products of splicing in response to a splicing modifier that promotes SMWN2 exon 7 inclusion than SMN2ind minigene polynucleotides. 40 In some embodiments, the proportion of RNA molecules comprising a nucleotide sequencehaving at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or 26 among RNA molecules obtained from cells comprising a polynucleotide of the present disclosure cultured in the 52 WO 2024 / 251925 PCT / EP2024 / 065689 presence of a splicing modifier that promotes SMN2 exon 7 inclusion is greater than 1 times, e.g. one of 21.01 times, 21.02 times, 21.03 times, 21.04 times, 21.05 times, 21.1 times, 21.2 times, 21.3 times, 21.4 times, 21.5 times, 21.6 times, 21.7 times, 21.8 times, 21.9 times, =2 times, 23 times, 24 times, 25 times, 26 times, 27 times, 28 times, 29 times or 210 times the proportion of RNA molecules comprising a 5 nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or 26 among RNA molecules obtained from cells comprising a SMN2ind minigene polynucleotide and cultured under the same conditions. It will be appreciated that the functional properties described herein are evaluated employing thesame 10 experimental conditions for the evaluation of cells comprising the different polynucleotides (i.e. the polynucleotide of the present disclosure, and the SMN2ind minigene polynucleotide). For example, the same cell type, the same splicing modifier that promotes SMN2 exon 7 inclusion, the same concentration of the splicing modifier that promotes SMN2 exon 7 inclusion, efc. are used, the same culture period is provided, and the cells are analysed in order to determine the proportion of RNA molecules comprising 15 the relevant nucleotide sequence and / or the level of the polypeptide of interest in the same way. In some embodiments, cells comprising a polynucleotide of the present disclosure cultured in the absence of a splicing modifier that promotes SMN / 2 exon 7 inclusion produce a population of RNA molecules having a decreased proportion of RNA molecules comprising a nucleotide sequence having at 20 least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or26, compared to the population of RNA molecules produced by cells comprising a SMNZ2ind minigene polynucleotide and cultured under the same conditions. That is, in some embodiments the polynucleotide of the present disclosure is more effective at excluding 25 a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or 26 in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion, compared to a SMN2ind minigene polynucleotide. That is, the polynucleotides of the present disclosure are less ‘leaky’ with respect to SMN2 exon 7 variant inclusion in the products of splicing in the absence of a splicing modifier that promotes SMNV2 exon 7 inclusion, compared to SMN2ind minigene polynucleotides. Leaky 30 production of mature RNA molecules comprising an SMN2 exon 7 variant (i.e. in the absence of a splicing modifier that promotes SMAV / 2 exon 7 inclusion) may also be referred to herein as ‘background’ production of such RNAmolecules. In some embodiments, the proportion of RNA molecules comprising a nucleotide sequence having at 35 least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or 26 among RNA molecules obtained from cells comprising a polynucleotide of the present disclosure cultured in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion is less than 1 times, e.g. $0.99 times, £0.95 times, <0.9 times, <0.85 times, <0.8 times, <0.75 times, <0.7 times, <0.65 times, <0.6 times, $0.55 times, <0.5 times, <0.45 times, <0.4 times, <0.35 times, <0.3 times, $0.25 times, <0.2 times, $0.15 40 __ times, $0.1 times, <0.05 times, or <0.01 times the proportion of RNA molecules comprising a nucleotide sequence having at least 80% sequence identity to a nucleotide sequence according to SEQ ID NO:11 or 53 WO 2024 / 251925 PCT / EP2024 / 065689 26 among RNA molecules obtained from cells comprising a SMN2ind minigene polynucleotide and cultured under the same concitions. In someembodiments, cells comprising a polynucleotide of the present disclosure (e.g. an ON-switch 5 polynucleotide) cultured in the presence of a splicing modifier that promotes SMN2 exon 7 inclusion display an increased level of protein expression of the polypeptide of interest, compared to the level of protein expression of the polypeptide of interest by cells comprising a SMN2ind minigene polynucleotide and cultured under the same conditions. That is, in some embodiments the polynucleotide of the present disclosure is more effective at promoting protein expression of the polypeptide of interest in the presence 10 of a splicing modifier that promotes SMN2 exon 7 inclusion, compared to a SMN2ind minigene polynucleotide. That is, the polynucleotides of the present disclosure are more responsive to induction of expression of the polypeptide of interest in the presence of a splicing modifier that promotes SMN / 2 exon 7 inclusion, compared to SMN2ind minigene polynucleotides. 15 It will beappreciated that for the purposes of such comparison, the different polynucleotides (i.e. the polynucleotide of the present disclosure, and the SMN2ind minigene polynucleotide) preferably encode the same polypeptide of interest. In some embodiments, the level of protein expression of the polypeptide of interest from cells comprising 20 a polynucleotide of the present disclosure (e.g. an ON-switch polynucleotide) cultured in the presence of a splicing modifier that promotes SMN2 exon 7 inclusion is greater than 1 times, e.g. one of 21.01 times, 21.02 times, 21.03 times, 21.04 times, =1.05 times, =1.1 times, 21.2 times, 21.3 times, =1.4 times, 21.5 times, 21.6 times, 21.7 times, 21.8 times, 21.9 times, 22 times, 23 times, 24 times, 25 times, 26 times, 27 times, 28 times, 29 times or 210 times the level of protein expression of the polypeptide of interest from 25 cells comprising a SMN2ind minigene polynucleotide and cultured under the same conditions. In some embodiments, cellscomprising a polynucleotide of the present disclosure (e.g. an ON-switch polynucleotide) cultured in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion display a decreased level of protein expression of the polypeptide of interest, compared to the level of 30 protein expression of the polypeptide of interest by cells comprising a SMN2ind minigene polynucleotide and cultured under the same conditions. That is, in some embodiments the polynucleotide of the present disclosure is more effective at preventing protein expression of the polypeptide of interest in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion, compared to a SMN2ind minigene polynucleotide. That is, the polynucleotides of the present disclosure are less ‘leaky’ with respect to 35 expression of the polypeptide of interest in the absence of a splicing modifier that promotes SMNZ2 exon 7 inclusion, compared to SMN2ind minigene polynucleotides. Leaky expression of the polypeptide ofinterest (.e. in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion) may also be referred to herein as ‘background’ expression of the polypeptide. 40 In some embodiments, the level of protein expression of the polypeptide of interest from cells comprising a polynucleotide of the present disclosure (e.g. an ON-switch polynucleotide) cultured in the absence of a splicing modifier that promotes SMN2 exon 7 inclusion is less than 1 times, e.g. <0.99 times, <0.95 times, 54 WO 2024 / 251925 PCT / EP2024 / 065689 <0.9 times, <0.85 times, <0.8 times, <0.75 times, <0.7 times, <0.65 times, <0.6 times, <0.55 times, <0.5 times, £0.45 times, <0.4 times, £0.35 times, <0.3 times, <0.25 times, <0.2 times, <0.15 times, <0.1 times, <0.05 times, or $0.01 times the level of protein expression of the polypeptide of interest from cells comprising a SMN2ind minigene polynucleotide and cultured under the same conditions. 5 In some embodiments, a polypeptide of interest expressed from apolynucleotide of the present disclosure comprises fewer extraneous additional amino acids (i.e. amino acids additional to the amino acid sequence of the polypeptide of interest) compared to a polypeptide of interest expressed from SMN2Zind minigene polynucleotide. In some embodiments, a polypeptide of interest expressed from a 10 polynucleotide of the present disclosure comprises a smaller N-terminal tag (i.e. formed of extraneous, additional amino acids in addition to the amino acid sequence of the polypeptide of interest) than a polypeptide of interest expressed from SMN2ind minigene polynucleotide. That is, in some embodiments, the polynucleotides of the present disclosure provide for the inducible expression of polypeptides of interest comprising fewer extraneous additional amino acids, relative to polypeptides of interest 15 expressed from SMN2ind minigene polynucleotide. Vectors The present disclosure provides vectors comprising the polynucleotides according to the presentdisclosure. It will be appreciated that a vector is also a polynucleotide, and so in some embodiments a 20 polynucleotide according to the present disclosure may be a vector. A ‘vector’ as used herein refers to a polynucleotide used as a vehicle to transfer exogenous nucleic acid into a cell. The vector may be a vector for expression of the nucleic acid in the cell (i.e. the vector may be an expression vector). Such vectors may include a promoter sequence operably linked to the nucleotide 25 sequence to be expressed. Vectors may also include a termination codon and expression enhancers. Any suitable vectors, promoters, enhancers and termination codons known in the art may be used in a vector according to the present disclosure.

Thus, a regulatory sequence is operably linked to the selected nucleic acid sequence if the regulatory sequence is capable of effecting transcription of the nucleic acid sequence. 35 ‘The resulting transcript(s) may then be translated into the desired polypeptide(s). Vectors contemplated in connection with the present disclosure include DNA vectors, RNA vectors, plasmids (¢.g. conjugative plasmids (e.g. F plasmids), non-conjugative plasmids, R plasmids, col plasmids, episomes), viral vectors (e.g. retroviral vectors, é.g. gammaretroviral vectors (e.g. murine 40 Leukemia virus (MLV)-derived vectors, é.g.

In some embodiments, the vector may be a eukaryotic vector, ie. a vector comprising the elements 5 necessary for expression of protein from the vector in a eukaryotic cell. In some embodiments, the vector may be a mammalian vector, €.g. comprising a cytomegalovirus (CMV) or SV40 promoter to drive protein expression.

In some embodiments, a vector is selected based on tropism for a cell type / tissue / organ in which it is desired to express the polypeptide of interest. For example, it may be desired to deliver the polynucleotide to, and / or express the polypeptide of interest in, a cell type / tissue / organ affected by a disease / condition to be treated / prevented in 25 accordance with the present disclosure (e.g. a cell type / tissue / organ in which the symptoms ofthe disease / condition manifest). For example, it might be desirable to deliver a polynucleotide of the present disclosure encoding a polypeptide of interest to neuronal cells / tissue, and vectors having a tropism for such cells / tissue may be 30 employed in such instances (i.e. neurotropic vectors). In preferred embodiments, the vector is an adeno-associated virus (AAV) vector. Adeno-associated virus vectors and their use to vector gene therapy is reviewed e.g. in Wang et al., Nat. Rev.

Conventional AAV have a 56 WO 2024 / 251925 PCT / EP2024 / 065689 single-stranded DNA genome, and depend on the DNA replication machinery of a transduced cell to synthesise the complementary strand, delaying transgene expression. By contrast, scAAV contain complementary sequences that spontaneously anneal upon infection, eliminating the requirement for DNA synthesis in the transduced host cell. Compared to classical, single-stranded AAV vectors, scAAV 5 vectors have been shown to provide for accelerated onset of transgene expression, and an increased level of transgene expression. In some embodiments, a vector may be an adeno-associated viral vector of one of the following serotypes: AAV9 (including AAV9 variants AAV-PHP.B and AAV9.45), AAV1, AAV2 (including AAV2 10 variant AAV2i8),AAV5, AAV6, AAV8, AAV10 or AAVrh74.

In some embodiments, the present disclosure provides the articles of the present disclosure for use, uses of articles of the present disclosure, and methods comprising administering: (i) a polynucleotide, vector, 30 cell or composition according to the present disclosure, and (ii) a splicing modifier that promotes SMN2 exon 7 inclusion, to a subject (e.g. a subject in need of treatment). In embodiments in accordance with aspects of the preceding paragraph, provision of (i) and (ii) may be as a combination therapy. In some embodiments, (i) and (ii) may be provided simultaneously or sequentially. 35 Simultaneous administration refers to administration of the two or more agents (e.g. a polynucleotide, vector, cell or composition according to the present disclosure, and a splicing modifier that promotes SMN2exon 7 inclusion) together, for example as a pharmaceutical composition containing both agents (i.e. aS a combined preparation), or immediately after each other (e.g. within 1, 4, 6, 8 or 12 hours), and 40 optionally via the same route of administration, e.g. to the same artery, vein or other blood vessel. Sequential administration refers to administration of one of the agents followed after a given time interval 64 WO 2024 / 251925 PCT / EP2024 / 065689 by separate administration of another agent. It is not required that the agents are administered by the same route, although this is the case in some embodiments. The time interval may be any time interval. In some embodiments, a splicing modifier that promotes SMN2 exon 7 inclusion is administered to a 5 subject after administration of a polynucleotide, vector, cell or composition according to the present disclosure. In some embodiments, a polynucleotide, vector, cell or composition according to the present disclosure is administered to asubject, and a splicing modifier that promotes SMN2 exon 7 inclusion is administered continuously to the subject thereafter. 10 In some embodiments, the splicing modifier that promotes SMN2 exon 7 inclusion is administered in a quantity, and / or with a periodicity, selected to achieve a desired level of expression of the polypeptide of interest. That is, in some embodiments the quantity of, and / or periodicity with which, a splicing modifier that promotes SMN2 exon 7 inclusion administered to a subject in accordance with the present disclosure is selected to achieve a desired level of expression of the polypeptide of interest. In some embodiments, 15 the quantity of, and / or periodicity with which, a splicing modifier that promotes SMNZ exon 7 inclusion is administered to a subject is adjusted through the course of its administration to change (i.e. decrease or increase) the level of expression of the polypeptide of interest in the subject. In embodiments wherein the polynucleotide of thedisclosure is an ON-switch polynucleotide, the quantity 20 and / or periodicity of administration of a splicing modifier that promotes SMNV2 exon 7 inclusion may be increased to increase the level of expression of the polypeptide of interest. Conversely, the quantity and / or periodicity of administration of a splicing modifier that promotes SMN / 2 exon 7 inclusion may be decreased to decrease the level of expression of the polypeptide of interest. 25 In embodiments wherein the polynucleotide of the disclosure is an OFF-switch polynucleotide, the quantity and / or periodicity of administration of a splicing modifier that promotes SMN2 exon 7 inclusion may be decreased to increase the level of expression of the polypeptide of interest. Conversely, the quantity and / or periodicity of administration of a splicing modifier that promotes SMN2 exon 7 inclusion may be increased to decrease the level of expression of the polypeptide of interest. 30 Further methods The present disclosure also providesa method for modifying a cell to comprise or express a polynucleotide according to the present disclosure, comprising introducing into a cell a polynucleotide or vector according to the present disclosure. 35 In some embodiments, introducing a polynucleotide or vector according to the present disclosure into a cell comprises transformation, transfection, electroporation or transduction (e.g. retroviral transduction). Transfection relates to the process of introducing nucleic acid into cells using means other than viral 40 infection and is hence a non-viral method. Transfection may be performed by physical / mechanical methods (including electroporation, sonoporation, magnetofection, gene microinjection and laser irradiation) or chemical methods (liposomal-based or non-liposomal based). Liposomal-based transfection 65 WO 2024 / 251925 PCT / EP2024 / 065689 reagents are chemicals which enable the formation of positively charged lipid aggregates, which can then merge with the phospholipid bilayerof the cell to facilitate the entry of foreign genetic material. Examples of liposomal-based transfection reagents include, but are not limited to Oligofectamine®, Lipofectamine® and DharmaFECT®. Non-liposomal transfection reagents include, but are not limited to, calcium 5 phosphate, nanoparticles, polymers, dendrimers and non-liposomal lipids. One example of a non- liposomal transfection reagent is polyethylenimine (PEI). Electroporation may be performed e.g. as described in Koh et al., Molecular Therapy — Nucleic Acids (2013) 2, e114, which is hereby incorporated by reference in its entirety. 10 Transduction is a process by which nucleic acids may be introduced into a cell by a virus or a viral vector. Accordingly, in some embodiments the polynucleotide is, or is comprised in, a viral vector, or the vector is a viral vector. Transduction of immune cells with viral vectors is described e.g. in Simmons and Alberola- lla, Methods Mol Biol. (2016) 1323:99-108, which is herebyincorporated by reference in its entirety. 15 Agents may be employed in the methods of the present disclosure to enhance the efficiency of transduction. Hexadimethrine bromide (polybrene) is a cationic polymer which is commonly used to improve transduction, through neutralising charge repulsion between virions and sialic acid residues expressed on the cell surface. Other agents commonly used to enhance transduction include e.g. the poloxamer-based agents such as LentiBOOST (Sirion Biotech), Retronectin (Takara), Vectofusin (Miltenyi 20 Biotech) and also SureENTRY (Qiagen) and ViraDuctin (Cell Biolabs). In some embodiments the methods comprise centrifuging the cells into which it is desired to introduce polynucleotide or vector according to the present disclosure in the presence of cell culture medium comprising viral vector(s) comprising the polynucleotide (referred to in the art as ‘spinfection’). 25 In some embodiments, the methods comprise culturing the cell under conditionssuitable for expression of the polynucleotide or vector by the cell. In some embodiments, the methods comprise culturing the cell under conditions suitable for transcription of a polydeoxyribonucleotide. In some embodiments, the methods comprise culturing the cell under conditions suitable for post-transcriptional processing (é.g. 30 splicing) of a polyribonucleotide. In some embodiments, the methods comprise culturing the cell under conditions suitable for translation of a polypeptide from a polyribonucleotide. Methods for culturing (including generating and / or expanding) populations of cells in vitro / ex vivo — including suitable culture conditions ( / .e. cell culture media, additives, stimulations, temperature, gaseous 35 atmosphere), cell numbers, culture periods efc. — are well known to the skilled person. Conveniently, cultures of cells according to the present disclosure may be maintained at 37°C in a humidified atmosphere containing 5% CC. The present disclosure also provides amethod for modifying a cell to express a polypeptide of interest, 40 comprising introducing into a cell a polynucleotide or vector according to the present disclosure. Where the polynucleotide is, or wherein the vector comprises / encodes, an OFF-switch, the cell may express the polypeptide of interest following introduction of the polynucleotide / vector into the cell. 66 WO 2024 / 251925 PCT / EP2024 / 065689 Where the polynucleotide is, or wherein the vector comprises / encodes, an ON-switch, the method may further comprise contacting the cell with a splicing modifier that promotes SMN2 exon 7 inclusion as described herein. Thus, in some embodiments, the method comprises (i) introducing into a cell a 5 polynucleotide or vector according to the present disclosure; and (ii) subsequently contacting the cell with a splicing modifier that promotes SMN2 exon 7 inclusion. ‘Contacting’ a cell with a splicing modifier may comprise bringing a cell into contact with a splicing modifier in a cell culture,and may be achieved by applying the splicing modifier to the cells in culture. 10 The present disclosure also provides a method for inhibiting expression of a polypeptide of interest in a cell. The method comprises contacting a cell comprising a polynucleotide or vector according to the present disclosure comprising / encoding an OFF-switch with a splicing modifier that promotes SMN2 exon 7 inclusion as described herein. 15 Any suitable quantity / concentration of a splicing modifier may be employed in the methods of the present disclosure.
