Kidney organoids were derived from a human iPS cell line with Ai9 (tdTomato) fluorescence-on reporter knocked into the AAVS1 safe harbor locus. Intact kidney organoids were transfected with CRISPR ribonucleoprotein complexes with and without molecular targeting agent (MTA) specific for podocytes. Genome editing events were detected by induction of tdTomato from the Ai9 reporter.

Using CRISPR/Cas9 genome editing in mouse embryos, the existing Rosa-CAG-LSL-tdTomato-WPRE conditional allele Gt(ROSA)26Sortm9(CAG-tdTomato)Hze (commonly referred to as Ai9) was modified to duplicate the guide target sequences for S. pyogenes and S. aureus Cas9 found on the 3' end of the loxP-flanked stop cassette [SpyCas9 5'GTATGCTATACGAAGTTAT (PAM AGG); SauCas9 5'ACGAAGTTATATTAAGGGTT(PAM CCGGAT)] onto the 5' end of the stop cassette. With this modification, a single guide RNA for S. pyogenes or S. aureus Cas9 can be used to mediate deletion of the stop cassette by non-homologous end joining and activation of tdTomato expression.

We utilized novel amphiphilic shuttle peptides to deliver base editor ribonucleoprotein (RNP) into the airways to edit airway epithelial cells (CCR5 locus) of rhesus monkeys. The Cas9-ABE8e RNP and shuttle peptides S10 or FSD315 were aerosolized into the rhesus monkey trachea. Seven days later, tissues were obtained and dissected, and airway epithelia collected from the trachea, mainstem, and segmental bronchi using cytology brushes. DNA was extracted from epithelial cells and subjected to high-throughput sequencing. Using the FSD315 shuttle peptide and Cas9-ABE8e, we achieved a mean editing efficiency of 2.8% at the CCR5 locus in airway epithelial cells (range 0.02 – 5.3%) depending on the anatomic region sampled. To visualize the biodistribution of the RNPs within the respiratory tract and in specific cell types, we delivered a Cy5-fluorescent peptide fused to a nuclear localization signal (NLS-Cy5) using the S10 peptide. The lungs were obtained 1 and 2 hours post-delivery, fixed, and examined by microscopy. Epifluorescence and confocal microscopy documented an effective intra-nuclear delivery of NLS-Cy5 into epithelial cells throughout the respiratory tract, including large, medium, and small airways, and alveolar regions. Ongoing analyses will identify the NLS-Cy5-positive epithelial cell types using co-localization with fluorescently-labeled antibodies. In summary, using a rhesus monkey model, following a single delivery of adenine base editor RNPs to the airways in a clinically relevant manner we achieved up to 5.3% editing efficiency of the CCR5 locus in airway epithelia, a level considered therapeutically relevant in cystic fibrosis.

ABSTRACT: The delivery of biologic cargoes to airway epithelial cells is challenging due to the formidable barriers imposed by its specialized and differentiated cells. Among cargoes, recombinant proteins offer therapeutic promise but the lack of effective delivery methods limits their development. Here, we achieve protein and SpCas9 or AsCas12a ribonucleoprotein (RNP) delivery to cultured human well-differentiated airway epithelial cells and mouse lungs with engineered amphiphilic peptides.

A dual vector strategy was employed: one self complementary vector delivering two single guide RNAs targeting the Rosa26 locus and one delivering CMV driven SaCas9 (single stranded vector). This strategy was evaluted with both AAV9 (n=4) and AAVcc47 (n=4) by intravenous injection in Ai9 mice. A total dose of 4e12vg was injected into each mouse and vectors mixed in a 1:1 ratio of cas9 to guide RNA (2e12vg of CMV Sacas9 vector and 2e12vg of the self complementary sgRNA vector) and organs were harvested 4 weeks post injection. Editing efficency was determined by calculating percent TdTomato+ cells normalized to Dapi+ cells in liver and heart.

ABSTRACT: Methods to deliver gene editing agents in vivo as ribonucleoproteins could offer safety advantages over nucleic acid delivery approaches. We report the development and application of engineered DNA-free virus-like particles (eVLPs) that efficiently package and deliver base editor or Cas9 ribonucleoproteins. By engineering VLPs to overcome cargo packaging, release, and localization bottlenecks, we developed fourth-generation eVLPs that mediate efficient base editing in several primary mouse and h ...

ABSTRACT: Recombinant adeno-associated viral (AAV) vectors are a promising gene delivery platform, but ongoing clinical trials continue to highlight a relatively narrow therapeutic window. Effective clinical translation is confounded, at least in part, by differences in AAV biology across animal species. Here, we tackle this challenge by sequentially evolving AAV capsid libraries in mice, pigs and macaques. We discover a highly potent, cross-species compatible variant (AAV.cc47) that shows improved attrib ...

Experiment Amphiphilic Peptides Deliver Base Editor RNPs to Rhesus Monkey Airway We utilized novel amphiphilic shuttle peptides to deliver base editor ribonucleoprotein (RNP) into the airways to edit airway epithelial cells (CCR5 locus) of rhesus monkeys. The Cas9-ABE8e RNP and shuttle peptides S10 or FSD315 were aerosolized into the rhesus monkey trachea. Seven days later, tissues were obtained and dissected, and airway epithelia collected from the trachea, mainstem, and segmental bronchi using cytology brushes. DNA was extracted from epithelial cells and subjected to high-throughput sequencing. Using the FSD315 shuttle peptide and Cas9-ABE8e, we achieved a mean editing efficiency of 2.8% at the CCR5 locus in airway epithelial cells (range 0.02 – 5.3%) depending on the anatomic region sampled. To visualize the biodistribution of the RNPs within the respiratory tract and in specific cell types, we delivered a Cy5-fluorescent peptide fused to a nuclear localization signal (NLS-Cy5) using the S10 peptide. The lungs were obtained 1 and 2 hours post-delivery, fixed, and examined by microscopy. Epifluorescence and confocal microscopy documented an effective intra-nuclear delivery of NLS-Cy5 into epithelial cells throughout the respiratory tract, including large, medium, and small airways, and alveolar regions. Ongoing analyses will identify the NLS-Cy5-positive epithelial cell types using co-localization with fluorescently-labeled antibodies. In summary, using a rhesus monkey model, following a single delivery of adenine base editor RNPs to the airways in a clinically relevant manner we achieved up to 5.3% editing efficiency of the CCR5 locus in airway epithelia, a level considered therapeutically relevant in cystic fibrosis.

Publication Engineered amphiphilic peptides enable delivery of proteins and CRISPR-associated nucleases to airway epithelia. The delivery of biologic cargoes to airway epithelial cells is challenging due to the formidable barriers imposed by its specialized and differentiated cells. Among cargoes, recombinant proteins offer therapeutic promise but the lack of effective delivery methods limits their development. Here, we achieve protein and SpCas9 or AsCas12a ribonucleoprotein (RNP) delivery to cultured human well-differentiated airway epithelial cells and mouse lungs with engineered amphiphilic peptides. These shuttle peptides, non-covalently combined with GFP protein or CRISPR-associated nuclease (Cas) RNP, allow rapid entry into cultured human ciliated and non-ciliated epithelial cells and mouse airway epithelia. Instillation of shuttle peptides combined with SpCas9 or AsCas12a RNP achieves editing of loxP sites in airway epithelia of ROSAmT/mG mice. We observe no evidence of short-term toxicity with a widespread distribution restricted to the respiratory tract. This peptide-based technology advances potential therapeutic avenues for protein and Cas RNP delivery to refractory airway epithelial cells.

By engineering VLPs to overcome cargo packaging, release, and localization bottlenecks, we developed fourth-generation eVLPs that mediate efficient base editing in several primary mouse and human cell types. Using different glycoproteins in eVLPs alters their cellular tropism. Single injections of eVLPs into mice support therapeutic levels of base editing in multiple tissues, reducing serum Pcsk9 levels 78% following 63% liver editing, and partially restoring visual function in a mouse model of genetic blindness. In vitro and in vivo off-target editing from eVLPs was virtually undetected, an improvement over AAV or plasmid delivery. These results establish eVLPs as promising vehicles for therapeutic macromolecule delivery that combine key advantages of both viral and nonviral delivery.

Publication Cross-species evolution of a highly potent AAV variant for therapeutic gene transfer and genome editing. Recombinant adeno-associated viral (AAV) vectors are a promising gene delivery platform, but ongoing clinical trials continue to highlight a relatively narrow therapeutic window. Effective clinical translation is confounded, at least in part, by differences in AAV biology across animal species. Here, we tackle this challenge by sequentially evolving AAV capsid libraries in mice, pigs and macaques. We discover a highly potent, cross-species compatible variant (AAV.cc47) that shows improved attributes benchmarked against AAV serotype 9 as evidenced by robust reporter and therapeutic gene expression, Cre recombination and CRISPR genome editing in normal and diseased mouse models. Enhanced transduction efficiency of AAV.cc47 vectors is further corroborated in macaques and pigs, providing a strong rationale for potential clinical translation into human gene therapies. We envision that ccAAV vectors may not only improve predictive modeling in preclinical studies, but also clinical translatability by broadening the therapeutic window of AAV based gene therapies.
