Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1-11 and 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Kerr et al. (WO 2020/154645; reference previously cited by the Examiner) in view of Bhanot et al. (WO 2011/156673; reference previously cited by the Examiner) and Hassler et al. (Nucleic Acids Research 2018; reference cited by Applicant).
Regarding claims 1, 4, 5, 6, 7, 8, 9, 10, and 11, Kerr et al. teaches that despite the advances made in the development of nucleic acid therapeutics that are evident in recent clinical achievements, the field of gene therapy is still severely limited by unwanted adverse events in recipients triggered by the therapeutic nucleic acids, themselves [0014]. Accordingly, there is a need in the field for a new technology that inhibits (e.g., reduces, ameliorates, mitigates, prevents) the immune response on administration of vectors or nucleic acid to a subject that permits expression of a therapeutic protein in a cell, tissue or subject capable of treatment of a wide variety of diseases [0015]. Further, Kerr et al. teaches pharmaceutical compositions comprising an inhibitor of the AIM2 inflammasome pathway for inhibiting (i.e., reducing or suppressing) an immune response in a subject suffering from a genetic disorder [0016]. Kerr et al. teaches that the human AIM2 protein is encoded by the AIM2 gene comprising nucleic acid sequence NM_004833.2 (SEQ ID NO: 600). Further, a gene silencing siRNA oligonucleotide duplexes targeted specifically to human AIM2 (NM_004833.2) can readily be used to knockdown AIM2 expression [00449]. Kerr et al. teaches nucleic acids containing known nucleotide analogs or modified backbone residues or linkages which include phosphorothioate and 2’-O-methyl ribonucleotides [0077]. Kerr et al. also teaches that oligonucleotides are chemically modified to alter and improve in vivo properties such as delivery, stability, life-time, folding, target specificity, as well as biological function and mechanism that directly correlates with therapeutic application [00173].
Kerr et al. SEQ ID NO: 600 (designated as Db) at positions 136 through 1529 has a 100% match to instant SEQ ID NO: 46 (designated as Qy) as shown in the alignment below.

Regarding claims 13 and 14, Kerr et al. teaches dendritic cells used in the production of a ceDNA vector for expression of an inhibitor of the immune response [00254].
Regarding claim 15, Kerr et al. teaches pharmaceutical compositions comprising one or more inhibitors of the immune response and a carrier [0022]. Further, the compositions wherein the inhibitor of AIM2 is an RNA inhibitor of AIM2 such as an siRNA specific for AIM2 or is encoded by the ceDNA [00449].
However, Kerr et al. does not teach a hydrophobically modified double stranded RNA molecule as recited in instant claim 1 wherein the sense strand comprises the sequence as recited in claim 2 and wherein the antisense strand comprises the sequence as recited in claim 3. Kerr et al. also does not teach the exact pattern of modifications of the sense strand and antisense strands of claims 4, 5, 7, 9, and 11.
Bhanot et al. teaches antisense compounds useful for modulating gene expression and associated pathways via antisense mechanisms of action such as RNaseH, RNAi and dsRNA enzymes as well as other antisense mechanisms based on target degradation or target occupancy [page 4, second paragraph]. Bhanot et al. teaches that antisense technology is emerging as an effective means for reducing the expression of certain gene products and may therefore prove to be uniquely useful in a number of therapeutic, diagnostic, and research applications for the modulation of the transcript [page 3, second full paragraph]. Bhanot et al. teaches modified oligonucleotides consisting of 10 to 30 linked nucleobases [page 25, first paragraph]. Further, the antisense compound has a nucleobase sequence at least 90% complementarity as measured over the entirety of said antisense compound [claim 6]. Bhanot et al. also designed many modified oligonucleotides using the principles described throughout the disclosure (see for example Tables 2-7). Specifically, Bhanot et al. teaches antisense compounds comprising one or more nucleosides wherein the sugar group has been modified to impart enhanced nuclease stability, increased binding affinity, or other beneficial biological property to the antisense compound [page 33, second full paragraph]. Further, examples of nucleosides having modified sugar moieties include 2’-F [page 33, third full paragraph]. Bhanot et al. also teaches modified oligonucleotides in which one or more internucleoside linkages are modified wherein a modified linkage is a substitution of a naturally-occurring phosphodiester linkage [page 32, fifth full paragraph]. Because Bhanot et al. teaches that modified internucleoside linkages substitute a naturally-occurring phosphodiester linkage, and Bhanot et al. teaches modified oligonucleotides comprising one modified internucleoside linkage, Bhanot et al. inherently teaches modified oligonucleotides with at least one naturally-occurring phosphodiester linkage. Bhanot et al. also teaches modified antisense compounds comprising one or more stabilizing groups attached to one or both termini to enhance properties such as nuclease stability. Specifically, terminal modifications such as cap structures protect the antisense compound from exonuclease degradation and can help in delivery and/or localization within a cell [page 43, third paragraph]. Bhanot et al. demonstrated that modified oligonucleotides designed to many different locations in a target nucleic acid achieve target nucleic acid inhibition (see Tables 2-7). Further, Bhanot et al. demonstrated in Example 4 that modified oligonucleotides also function in vivo including in the relief of symptoms of a disease associated with the target molecule [pages 62-64].
Hassler et al. teaches that an asymmetric, cholesterol-modified siRNA was used to compare the impact of partially or fully modified scaffolds on conjugate-mediated distribution and silencing in vivo. The asymmetric design, termed hsiRNAs (15-nucleotide passenger strand with a 3’-conjugate and 20-nucleotide guide strand) lowers the melting temperature of the double-strand region, to facilitate the dissociation of the non-cleavable modified guide strand from the RISC during loading [page 2188, right column, last paragraph]. Figure 1A (reproduced below) is the chemical structure, modification pattern, and molecular model of partially (hsiRNA) and fully modified (FM-hsiRNA) hydrophobic siRNA [page 2187]. Hassler et al. also teaches that cholesterol conjugation to partially modified hsiRNAs results in robust cellular uptake in vitro and potent local silencing in vivo [page 2189, left column, first full paragraph] and chol-FM-hsiRNA showed significantly enhanced efficacy following passive uptake [page 2189, right column, first paragraph].

Although Kerr et al. does not teach a double stranded RNA molecule, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to design a hydrophobically modified dsRNA according to claim 1 and arrive at the instantly recited SEQ ID NOS. using the design principles taught by Bhanot et al. and Hassler et al. because it would have amounted to applying known design principles for preparing antisense compounds, to a human AIM2 sequence, by known means to yield predictable results. The skilled artisan would have had a reasonable expectation of success in preparing the modified oligonucleotides because as evidenced by Bhanot et al. it was well within the purview of the skilled artisan, and routine in the art, to design, test, and identify modified oligonucleotides that effectively inhibit the target nucleic acid wherein the modified oligonucleotides consist of 10 to 30 linked nucleobases and the antisense compound has a nucleobase sequence at least 90% complementarity over the entirety of the antisense compound and as evidenced by Hassler et al. a fully modified hydrophobic siRNA lowers the melting temperature of the double-strand region, to facilitate the dissociation of the non-cleavable modified guide strand from the RISC during loading. One would have been motivated to modify the oligonucleotide of Kerr et al. using the design principles of Bhanot et al. and Hassler et al. to provide the oligonucleotide for the purposes of knocking down AIM2 expression because Kerr et al. taught that there is a need in the field for a new technology that inhibits (e.g., reduces, ameliorates, mitigates, prevents) the immune response on administration of vectors or nucleic acid to a subject that permits expression of a therapeutic protein in a cell, tissue or subject capable of treatment of a wide variety of diseases and also taught pharmaceutical compositions comprising an inhibitor of the AIM2 inflammasome pathway for inhibiting (i.e., reducing or suppressing) an immune response in a subject suffering from a genetic disorder.

These arguments are not found persuasive. Kerr et al. teaches that inhibition of the AIM2 mRNA can be by gene silencing RNAi molecules according to methods commonly known by a skilled artisan. For example, a gene silencing siRNA oligonucleotide duplex targeted specifically to human AIM2 (NM_004833.2) can readily be used to knockdown AIM2 expression. Further, AIM2 mRNA can be successfully targeted using siRNAs and other siRNA molecules may be readily prepared by those of skill in the art based on the known sequence of the target mRNA. Accordingly, in avoidance of any doubt, one of ordinary skill in the art can design nucleic acid inhibitors such as RNAi agents to the nucleic acid sequence of NM_004833.2 which is SEQ ID NO: 600 [00449]. Applicant's amendment necessitated the incorporation of the Hassler et al. reference presented in this Office action because Kerr et al. and Bhanot et al. did not teach a hydrophobically modified dsRNA molecule. Although Kerr et al. does not teach a double stranded RNA molecule, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to design a hydrophobically modified dsRNA according to claim 1 and arrive at the instantly recited SEQ ID NOS. using the design principles taught by Bhanot et al. and Hassler et al. because it would have amounted to applying known design principles for preparing antisense compounds, to a human AIM2 sequence, by known means to yield predictable results.

These arguments are not found persuasive. Contrary to Applicant’s assertions that Kerr et al. is silent regarding a mouse AIM2 sequence, the mouse AIM2 sequence (instant SEQ ID NO: 48; designated as Db) and human AIM2 sequence (instant SEQ ID NO: 46; designated as Qy) are conserved and thus share levels of identity as shown in the alignment below.

Kerr et al. teaches that inhibition of the AIM2 mRNA can be by gene silencing RNAi molecules according to methods commonly known by a skilled artisan. For example, a gene silencing siRNA oligonucleotide duplex targeted specifically to human AIM2 (NM_004833.2) can readily be used to knockdown AIM2 expression. Further, AIM2 mRNA can be successfully targeted using siRNAs and other siRNA molecules may be readily prepared by those of skill in the art based on the known sequence of the target mRNA. Accordingly, in avoidance of any doubt, one of ordinary skill in the art can design nucleic acid inhibitors such as RNAi agents to the nucleic acid sequence of NM_004833.2 which is SEQ ID NO: 600 [00449].

These arguments are not found persuasive. Kerr et al. teaches that an inhibitor of AIM2 is for example an antibody or antigen-binding fragment that binds AIM2 [00445], an anti-human ASC monoclonal antibody [00446], P202 [00447], a small molecule compound [00448], or a RNA inhibitor [00449]. Thus, Kerr et al. provides a suggestion to use an RNAi inhibitor of AIM2 and does not teach away nor disparage the use of an RNAi as an inhibitor of AIM2.
