Definitions
- This invention relates to polynucleotides comprising optimized AGA open reading frame (ORF) sequences, vectors comprising the same, and methods of using the same for delivery of the ORF to a cell or a subject and to treat
- ORF open reading frame
- AGU aspartylglucosaminuria
- Aspartylglucosaminidase (AGA, N4-(P-N-Acetylglucosaminyl)-L- Asparaginase, EC 3.5.1.26) is a lysosomal hydrolase that participates in one of the final steps during the degradation of N-glycosylated proteins.
- AGA cleaves the bond between N-acetylglucosamine and asparagine after the polypeptide backbone has been degraded.
- AGA is synthesized as a single-chain precursor molecule that soon after synthesis in the endoplasmic reticulum becomes cleaved into two subunits after dimerization of two precursor molecules.
- AGA belongs to the group of so-called N-terminal nucleophile (NTN) hydrolases, as the free -amino group of Thr206 is involved in the catalysis as the base, whereas the OH group of Thr206 functions as a nucleophile during the catalysis.
- NTN hydrolases which in addition to AGA also include, e.g., the proteasome ⁇ subunit and penicillin acylase, show very little similarity at the amino acid sequence level, but they exhibit a highly similar folded structure.
- AGU aspartylglucosaminuria
- OMIM 208400 a lysosomal storage disorder that is characterized by progressive mental retardation and some skeletal abnormalities.
- AGU patients are born seemingly normal, but the progressive course of the disease manifests in, e.g., developmental delay, loss of speech and coarse facial features early in childhood. In adulthood, most AGU patients are severely retarded and require special care.
- AGU is a rare disease with an unknown prevalence in most populations, but it is enriched in the Finnish population.
- AGUpin-m ajor Due to a founder effect, a specific gene defect designated as AGUpin-m ajor is found in homozygous form in most Finnish AGU patients, although the parents do not show any consanguinity.

- disorder associated with aberrant activity of an AGA gene product refers to a disease, disorder, syndrome, or condition that is caused by or a symptom of decreased or altered activity of the AGA gene product in a subject relative to the activity in a normal subject or in a population.
- transduction of a cell by a virus vector means entry of the vector into the cell and transfer of genetic material into the cell by the incorporation of nucleic acid into the virus vector and subsequent transfer into the cell via the virus vector.
- efficient transduction or “efficient tropism,” or similar terms, can be determined by reference to a suitable positive or negative control (e.g., at least about 50%, 60%, 70%, 80%, 85%, 90%, 95% or more of the transduction or tropism, respectively, of a positive control or at least about 110%, 120%, 150%, 200%, 300%, 500%, 1000% or more of the transduction or tropism, respectively, of a negative control).

- a "3' portion” of a polynucleotide indicates a segment of the polynucleotide that is downstream of another segment.
- the term “3' portion” is not intended to indicate that the segment is necessarily at the 3 ' end of the polynucleotide, or even that it is necessarily in the 3 ' half of the polynucleotide, although it may be.
- a "5 ' portion” of a polynucleotide indicates a segment of the polynucleotide that is upstream of another segment.
- the term “5' portion” is not intended to indicate that the segment is necessarily at the 5' end of the polynucleotide, or even that it is necessarily in the 5' half of the polynucleotide, although it may be.
- polypeptide encompasses both peptides and proteins, unless indicated otherwise.
- a "polynucleotide,” “nucleic acid,” or “nucleotide sequence” is a sequence of nucleotide bases, and may be RNA, DNA or DNA-R A hybrid sequences (including both naturally occurring and non-naturally occurring nucleotide), but is preferably either a single or double stranded DNA sequence.
- ORF open reading frame
- codon-optimized refers to a gene coding sequence that has been optimized to increase expression by substituting one or more codons normally present in a coding sequence (for example, in a wild-type sequence, including, e.g. , a coding sequence for AGA) with a codon for the same (synonymous) amino acid.
- a coding sequence for example, in a wild-type sequence, including, e.g. , a coding sequence for AGA
- the optimization substitutes one or more rare codons (that is, codons for tRNA that occur relatively infrequently in cells from a particular species) with synonymous codons that occur more frequently to improve the efficiency of translation.
- Codon optimization can also increase gene expression through other mechanisms that can improve efficiency of transcription and/or translation.
- Strategies include, without limitation, increasing total GC content (that is, the percent of guanines and cytosines in the entire coding sequence), decreasing CpG content (that is, the number of CG or GC dinucleotides in the coding sequence), removing cryptic splice donor or acceptor sites, and/or adding or removing ribosomal entry sites, such as Kozak sequences.
- a codon-optimized gene exhibits improved protein expression, for example, the protein encoded thereby is expressed at a detectably greater level in a cell compared with the level of expression of the protein provided by the wild-type gene in an otherwise similar cell.
- sequence identity has the standard meaning in the art. As is known in the art, a number of different programs can be used to identify whether a polynucleotide or polypeptide has sequence identity or similarity to a known sequence. Sequence identity or similarity may be determined using standard techniques known in the art, including, but not limited to, the local sequence identity algorithm of Smith & Waterman, Adv. Appl. Math. 2:482 (1981), by the sequence identity alignment algorithm of Needleman & Wunsch, J. Mol. Biol. 48:443 (1970), by the search for similarity method of Pearson & Lipman, Proc. Natl. Acad. Sci.
- PILEUP creates a multiple sequence alignment from a group of related sequences using progressive, pairwise alignments. It can also plot a tree showing the clustering relationships used to create the alignment. PILEUP uses a simplification of the progressive alignment method of Feng & Doolittle, J Mol. Evol. 35:351 (1987); the method is similar to that described by Higgins & Sharp, CABIOS 5: 151 (1989).
- BLAST algorithm Another example of a useful algorithm is the BLAST algorithm, described in Altschul et al., J. Mol. Biol. 215:403 (1990) and Karlin et al, Proc. Natl. Acad. Sci. USA £0:5873 (1993).
- a particularly useful BLAST program is the WU-BLAST-2 program which was obtained from Altschul et al, Meth. Enzymol, 266:460 (1996); blast. wustl/edu/blast/README.html.
- WU-BLAST-2 uses several search parameters, which are preferably set to the default values. The parameters are dynamic values and are established by the program itself depending upon the composition of the particular sequence and composition of the particular database against which the sequence of interest is being searched; however, the values may be adjusted to increase sensitivity.
- a percentage amino acid sequence identity value is determined by the number of matching identical residues divided by the total number of residues of the "longer" sequence in the aligned region.
- the "longer" sequence is the one having the most actual residues in the aligned region (gaps introduced by WU-Blast-2 to maximize the alignment score are ignored).
- percent nucleic acid sequence identity is defined as the percentage of nucleotide residues in the candidate sequence that are identical with the nucleotides in the polynucleotide specifically disclosed herein.
- the alignment may include the introduction of gaps in the sequences to be aligned.
- the percentage of sequence identity will be determined based on the number of identical nucleotides in relation to the total number of nucleotides.
- sequence identity of sequences shorter than a sequence specifically disclosed herein will be determined using the number of nucleotides in the shorter sequence, in one embodiment.
- percent identity calculations relative weight is not assigned to various manifestations of sequence variation, such as insertions, deletions, substitutions, etc.
- identities are scored positively (+1) and all forms of sequence variation including gaps are assigned a value of "0," which obviates the need for a weighted scale or parameters as described below for sequence similarity calculations.
- Percent sequence identity can be calculated, for example, by dividing the number of matching identical residues by the total number of residues of the "shorter" sequence in the aligned region and multiplying by 100. The "longer" sequence is the one having the most actual residues in the aligned region.
- an "isolated" nucleic acid or nucleotide sequence ⁇ e.g., an "isolated DNA” or an “isolated RNA" means a nucleic acid or nucleotide sequence separated or substantially free from at least some of the other components of the naturally occurring organism or virus, for example, the cell or viral structural components or other polypeptides or nucleic acids commonly found associated with the nucleic acid or nucleotide sequence.
- an "isolated" polypeptide means a polypeptide that is separated or substantially free from at least some of the other components of the naturally occurring organism or virus, for example, the cell or viral structural components or other polypeptides or nucleic acids commonly found associated with the polypeptide.
- the term "modified,” as applied to a polynucleotide or polypeptide sequence, refers to a sequence that differs from a wild-type sequence due to one or more deletions, additions, substitutions, or any combination thereof.
- isolated or “purify” (or grammatical equivalents) a virus vector, it is meant that the virus vector is at least partially separated from at least some of the other components in the starting material.
- treat By the term “treat,” “treating,” or “treatment of (or grammatically equivalent terms) it is meant that the severity of the subject's condition is reduced or at least partially improved or ameliorated and/or that some alleviation, mitigation or decrease in at least one clinical symptom is achieved and/or there is a delay in the progression of the condition and/or prevention or delay of the onset of a disease or disorder.
- prevent refers to a delay in the onset of a disease or disorder or the lessening of symptoms upon onset of the disease or disorder.
- the terms are not meant to imply complete abolition of disease and encompasses any type of prophylactic treatment that reduces the incidence of the condition or delays the onset and/or progression of the condition.
- a “treatment effective” amount as used herein is an amount that is sufficient to provide some improvement or benefit to the subject.
- a “treatment effective” amount is an amount that will provide some alleviation, mitigation, decrease or stabilization in at least one clinical symptom in the subject.

- Intrathecal 2 Increased enzyme activity, reduced the substrate accumulation, but not completely effective at improving behavioral phenotype
- Intrathecal 10 Increased enzyme activity, reduced the substrate accumulation and normalized behavioral phenotype. Note that the IT dose is 10-fold lower compared to the high IV, but the over rescue was comparable.
- Intravenous 20 Increased enzyme activity, reduced the substrate accumulation, but not completely effective at improving behavioral phenotype
- Intravenous 100 Increased enzyme activity, reduced the substrate accumulation and normalized behavioral phenotype
- mice Behavioral improvements in KO mice. Improvement in the levels of AGA enzyme and reduction of the AGA substrate in the KO were achieved following AAV9/AGA administration. Based on the pathophysiology of the disease, correction of the underlying insult (substrate accumulation) is expected to halt or slow the neurodegeneration, resulting in a phenotypic rescue. To test this directly, treated mice were evaluated at 14 months old, an age at which the AGU mice show reduced mobility in an open field test. [0178] Patients with AGU tend to withdraw, become calm, lack enthusiasm and sit quietly for hours as the disease progresses. Open field exploration test in mice is a tool to assess novel environment exploration, anxiety-related behavior and general locomotor activity.
- mice were tested in parallel as reference controls.
- AGA KO mice were randomized into one of 5 groups: 1) untreated, 2) IV high dose, 3) IV low dose, 4) IT high dose, and 5) IT low dose. This age is significant, since neuropathology is present in the mice at this age.
- all mice were assayed for their mobility with the open field test. Distance travelled, high mobility time, and immobility time were quantified by an automated Noldus video tracking system. These tests reflect the activity and anxiety in the treated and untreated KO mice.
- mice were highly mobile, inspecting the new/unfamiliar surroundings, and they spent less time immobile/stationary displaying higher levels of anxiety and activity (FIG. 7).
- the untreated KO mice displayed lower exploratory behavior and mobility relative to heterozygotes.
- the treated KO mice showed improvement in their mobility compared to the untreated cohorts.
- Cohorts treated with higher dose levels spent significantly more time mobile, although the distances traveled during this period were not significantly different from untreated mice. It should be noted that the treatment was initiated in mice that were 6 months old, an age when significant brain pathology and degeneration is present.
- mice injected at 2 months old are ongoing. We interpret these results as showing a significant behavioral normalization of mice treated after the onset of disease pathology, by either IV or IT administration of AAV9/AGA, at the high dose. This is a pivotal result in that it demonstrates a clear phenotypic benefit to the AGU mice, and it defines a minimally effective dose since the low dose was unable to fully rescue the disease phenotype.
- AGU Histopathology Lysosomal hypertrophy, as evidenced by cellular vacuo lation, in visceral organs of the KO mice resembles human AGU
- AGA enzyme expression acid activity in target tissues.
- the human AGA gene was optimized for code usage.
- the optimized sequence encoding either Ser 149 or Thrl49 (two naturally occurring human variants) were cloned into the pcDNA3 expression vector.
- the expression and activity of the optimized variants were compared with constructs exhibiting the normal human cDNA sequence.
- a significantly higher proteins expression was obtained in HEK and HeLa cells of the codon optimized variants, as compared to the respective non-optimized ones (FIGS 9A-9D).
- the normalized enzyme activities were significantly higher with the optimized AGA variants (FIGS 9E-9F).
