Cellastra Inc., a developer of disruptive gene therapies, is a private biotech company based in the San Francisco Financial District. It was founded and managed by proven industry executives with a track record of execution. Cellastra’s mission is to develop Disruptive, First or Best in Class Gene Therapies. Cellastra Proprietary Technology - Gene Vector- Anti-scarring peptide: Cellastra is developing viral gene vector-mediated intervention to address an area of great unmet medical needs in scarless wound healing after surgery and respiratory infections: 1. Surgery: Prevent excessive dermal scarring, e.g., after breast augmentation surgery, and C section. 2. Respiratory Infections: Prevent an excessive immune response, tissue damage, and scarring/fibrosis in high-risk patient groups with respiratory infections such as COVID-19 (coronavirus disease 2019) and RSV (respiratory syncytial virus). Scarless wound healing can be achieved by using a gene vector encoding for endogenous continuous production of the anti-scarring peptides at the site of injury. Thus, two gene vectors are planned for development (Cellexa applied under the skin after surgery and Virexa inhaled into the lungs in COVID-19 and other respiratory infections). The development of these vectors is built and expands upon a foundation of scientific proof of concept data of the anti-scarring peptide ensereptide.

Circle Pharma initiated operations in June 2014 with seed funding from Pfizer, Inc. and Mission Bay Capital, LLP; we received additional seed funding from ShangPharma Investment Group Limited in November 2015. They recently raised Series B and Series C financing from The Column Group and NextTech Invest. Circle Pharma design and develop bioavailable macrocyclic peptide therapeutics against important clinical targets. They do this by applying a computational structure-based design approach that combines physics (conformational modeling), chemistry (innovative molecular components) and biology (protein target structure and function). They have selected intracellular protein-protein interactions that play key roles in cancer as the initial target group for our internal pipeline development. Circle is taking a new approach to the development of macrocylic peptide therapeutics that is based on the pioneering work of its founders to understand and computationally predict drug-like properties of macrocycles. Circle is advancing this understanding to design novel, inherently permeable macrocyclic peptide drug candidates against Circle’s internal targets and those of our collaboration partners. Circle Pharma workflow includes the use of proprietary algorithms to design large, conformationally diverse, virtual libraries of cell permeable macrocyclic scaffolds that incorporate natural and non-natural backbone components. They deploy these virtual scaffold libraries in subsequent design steps that include the incorporation of functional side chains selected for both target binding and maintenance of permeability. Candidate compounds are synthesized and tested for both permeability and target affinity and the results are used to inform subsequent design cycles.

Currently, we are utilizing a peptide nanoscaffold based approach for treating COVID-19 without a gene therapy component, with the goal of creating a combined antidote-vaccine. My expertise lies in targeted gene delivery, nano- and biomaterials, computational modeling of peptides, binding simulations, immunoengineering, as well as CRISPR and TALEN based gene editing. At Ligandal, we have demonstrated peptide-based delivery of CRISPR, RNA, DNA, siRNA, and a range of genes or proteins to virtually any cell type.

Medikine is a biopharmaceutical company with a mission to transform the discovery of oncology, autoimmune disorder, and infectious disease therapeutics by employing a disruptive and versatile drug discovery platform that generates modular “PEPTIKINES” that are smaller in molecular size than, and structurally unrelated to, the natural cytokine proteins they emulate. These PEPTIKINES are readily amenable to further enhancement for desired pharmacokinetics or added pharmacologic features. Medikine’s lead product candidate MDK-703, which is planned to enter clinical trials in 2022, is an Fc-fusion protein containing an IL-7 PEPTIKINE, which emulates the beneficial properties of IL-7, a cytokine critical to maintaining T cell response. An important feature is its avoidance of the generation of neutralizing antibodies to native IL-7. Medikine has also identified novel PEPTIKINES that activate the IL-2/15βγc receptor and is exploring their use in bispecifics with differentiated profiles, including an IL-7R and IL-2/15Rβγc dual agonist and a cell-targeted IL-2/15Rβγc attenuated agonist.

Unlocking the potential of macrocycle drug discovery through machine learning and massively parallel synthesis

Vault Pharma’s technology platform uses the human vault particle to deliver peptide payloads for unique immune signaling. We exploit the natural function of the human vault particle which is an immunological signal alert progenitor. Natural vault function is most notably characterized by vault particles being rapidly and robustly ingested by antigen presenting cells, APCs, specifically macrophages and dendritic cells. This favorable and natural property of vaults sets in motion an elegant and robust immune response that is non-inflammatory and results in many propitious effects including stimulation of antigen specific CD4 and CD8 T cells. Recombinant Vaults Allow for Novel Access To Immune Responses Recent data in multiple animal and cell models both published and unpublished demonstrate that vaults can and do produce an elegant, sophisticated and highly desired immune response characterized by unusually high and previous undescribed cellular immune responses (both CD4 and CD8) without inflammation, or cytokine storm. Evidence demonstrates that VPI-101 elicits an enhanced TIL response which recognize and kill cancer. Furthermore, animal studies demonstrate that VPI-101 vaults down regulate the tumor immune suppressive environment; reduced immune suppressive cells (reduce effective response) like T-regulatory cells (Tregs), myeloid derived suppressor cells (MDSC), IL-10 T cells, and induce systemic antitumor responses (stimulating splenic T-cell lytic activity against parental tumor cells). Recombinant vault particles are safe and non-immunogenic. Human vaults are identical in every person; therefore, they can be delivered as an off-the-shelf therapeutic. Vaults are highly stable, scalable, and homogenous in production
