GREETING

Founder&CEO
Daewoong Jo,Ph.D.

Dear Sir/Madam,..

Please allow me to introduce Cellivery Therapeutics, Incorporated (referred to as the “Company” or “Cellivery” henceforth). The mission of Cellivery is to become a leading protein-based drug discovery company within the biotechnology industry, developing therapeutics capable of entering cells through proprietary Therapeuticmolecule Systemic Delivery Technology (TSDT). A well-rounded management team and active advisory board members are uniquely suited, through technical and industry experiences, to fulfill the Company’s mission to commercialize life-saving therapeutics and cultivate revenue-generating partnerships with companies in biotechnology and pharmaceuticals.

The plasma membrane normally acts as an impermeable barrier, preventing proteins and other macromolecules from entering cells. However, Cellivery’s proprietary TSDT allows functionally active macromolecules to rapidly traverse cellular membranes. The process utilizes specialized hydrophobic cell-penetrating peptides (CPPs), termed Macromolecule Transduction Domains (MTDs) that can be engineered into peptides, whole proteins, DNA fragments, and other bioactive substances such as drugs. With additional subcellular trafficking signals, transduced macromolecules can be guided to specific cellular locations, providing an effective way to influence intracellular protein function.

Previously, recombinant cell-permeable (CP-) proteins fused to MTDs to deliver therapeutically active cargo proteins into live cells were developed, but due to their low solubility and yield, the fusion proteins expressed in bacterial system were difficult to purify in soluble form. To address the crucial weakness for further clinical development of the CP-Proteins as protein-based biotherapeutics, tremendously enhanced form of the hydrophobic CPP, named advanced MTD (aMTD), was developed through critical factor-based peptide analysis. In Cellivery, we have demonstrated that TSDT enabled by the novel aMTDs could provide novel protein therapies against cancer and other lethal diseases.

The valuation of the company, as with most companies in this market, will be based on the value of its intellectual property, ongoing partnerships, and pipelines, rather than on current revenues. The scientific expertise and core competencies of the company will allow Cellivery to become the world’s foremost biotechnology company devoted to the creation and use of cell-permeable protein therapeutics.

TSDT is a platform technology with many applications in biomedical research fields. In particular, TSDT provides a method to identify and validate potential therapeutic targets, and to deliver protein-based drugs into live cells and animals. To maximize the value of the company’s intellectual property, the company will out-license specific technologies.

Cellivery will also use its core transduction technology to build novel protein-based drug discovery platforms that rapidly identify functional protein interactions. These platform developmental expenses will be defrayed, in some cases, by establishing long-term corporate research and development alliances. Such alliances will generate near-term recurring revenue for the company.

Cellivery’s therapeutic drug candidates are being developed for the prevention of life-threatening lethal diseases, including various cancer. The company’s subsequent drug discovery programs will focus on other diseases, in which the transient suppression of either symptoms or etiology would produce long-term benefits, that are both cost-effective and associated with a high quality of life.

Cellivery's long-term goal is to continue to increase the value of shareholders by building revenue-generating partnerships, establishing a strong intellectual properties and drug portfolios, and creating proprietary biological information. Our goal is to have an initial public offering after the development phase or within 3 years, depending on markets.

In conclusion, I believe TSDT has considerable promise and Cellivery will be able to enhance and extend TSDT and move the technology from conceptual to therapeutic reality.

I hope my comments have been useful to you in understanding the company’s goals and values.

Sincerely,

Daewoong Jo, Ph.D.

TSDT Platform

Advanced Macromolecule Transduction Domain (aMTD)-enabled Therapeuticmolecule Systemic Delivery Technology (TSDT), a powerful platform technology for the discovery and development of the new medicinal drug, is enabled with hydrophobic cell-penetrating peptides (CPPs) that provide cell-permeability of therapeuticmolecules in-vivo.

Previous generations of hydrophobic CPPs were derived from the hydrophobic signal peptides of secreted proteins and used to deliver biologically active peptides and proteins systemically in animals. However, many efforts to develop cell-permeable therapeutic proteins by using previous generations of hydrophobic CPP sequences for further clinical development and applications have been hampered by poor solubility of the recombinant proteins in physiological buffer condition and relatively low cell-permeability. To develop improved hydrophobic CPPs, Cellivery analyzed sequences from all 1st and 2nd generation hydrophobic CPP sequences and identified 6 ‘critical factors’ associated with efficient protein translocation across the plasma membrane. 136 synthetic peptides were developed that incorporated different permutations of the 6 CFs and have been designated advanced macromolecule transduction domains

Compared to the previous generations of CPPs, proteins containing aMTDs displayedan average of 13±1.1-folds greater cell-penetrating ability.

aMTD-mediated therapeuticmolecule uptake involves direct penetration of the plasma membrane. In particular, uptake did not require ATP, cell surface proteins or microtubule function. The uptake, however, was abolished in the presence of calcium chelator and also blocked in temperature at 4°Csuggesting the requirements of aMTD-mediated uptake aremembrane integrity and fluidity.

Finally, aMTD-enabled TSDT platform is able to internalize the therapeutic moleculeinto cellsand tissues systemically via cell-to-cell delivery.

However, because macromoleculeshave high target specificity with the binding partner, it makes mechanism specific-targeted therapy possible. In general, having entered the cell, CP-Proteins spread everywhere in a similar way as small molecule drugs. However, unlike small molecule drugs, aMTD/SD-fused recombinant protein does not function without binding to its correct target because CP-Proteins possess the ability of interact with its targets specifically. In this case, affinity plays a role of target receptor in the distribution of cells. Moreover, affinity controls the selectivity and defines the specificity. Ultimately, CP-Proteins will produce fewer off-target effects than small molecule drugs by virtue of their grater specificity.

aMTD-enabled TSDT platform can be applied to many moieties of therapeuticmolecules across different disease areas. Therapeutic moleculeswith proven biological activities can easily be developed into cell-permeable medicinal candidate by simplyfusing aMTD empirically. TSDT enabled by aMTD can efficiently and cost-effectively be used as platform technology for discovery/development of protein-based biotherapeutics.

iCP-SOCS3

Suppressor of cytokine signaling 3 (SOCS3) functions as a negative-feedback regulator of JAK/STAT signaling that suppresses JAK kinase activity and promotes degradation of the activated cytokine receptor complex resulting in the anti-inflammatory and anti-cancer effect due to suppression of inflammation-inducing cytokine signaling. Loss of SOCS3 enhances the growth and survival of some solid tumors; therefore, methods to replenish intracellular levels of the protein may provide an effective therapy against solid tumors dependent on JAK/STAT signaling for growth or survival.

To control the JAK/STAT signaling negatively, we previously developed cell-permeable SOCS3 recombinant protein (CP-SOCS3) enabled by a previous generation of hydrophobic CPP (membrane-translocating motif: MTM) derived from FGF4 in order to explore the possibility of blocking cytokine-induced signaling pathway (Nat Med. 2005;11:892-898). However, these previously developed recombinant CP-SOCS3 proteins showed extremely low solubility, yield, and relative low cell- and tissue-permeability. To overcome these limitations, we have newly developed recombinant SOCS3 proteins fused to novel hydrophobic CPP, advanced macromolecule transduction domain (aMTD), to greatly increase their solubility, manufacturing yield, and efficiency of membrane penetrating ability named as improved cell-permeable (iCP)-SOCS3 proteins.

iCP-SOCS3 has the therapeutic applicability to treat various cancers includinghepatoma, pancreatic cancer, lung cancer, colorectal cancer, gastric cancer and glioblastoma,and inflammatory disorders through protein-based intracellular replacement therapy.

iCP-SOCS3 suppressed cancer-associated phenotypes, induced apoptosis and triggered alteration in biomarker expression (e.g., cell cycle, apoptosis, angiogenesis) consistent withpreviously described effects of SOCS3. In contrast, iCP-SOCS3 did not affect proliferation and apoptosis of non-cancerous cells. In addition, iCP-SOCS3 also significantly suppressed the tumor growth in various cancer cell-derived xenograft (CDX) models and significantly inhibited tumor angiogenesis in vivo, leading to inhibition of tumor angiogenesis. Furthermore, iCP-SOCS3 inhibited STAT3 phosphorylation and reduced secretion of proinflammatory cytokines leading to attenuated progression of inflammatory bowel disease (IBD) and acute liver injury.

iCP-Parkin

A BBB-Crossing Protein Savior For Damaged Neurons

Parkinson’s disease (PD) isa neurodegenerative disease characterized by the loss of dopaminergic (DA) neurons, leading to clinical symptoms such as exercise relaxation, tremor, and postural instability. The pathological hallmark of PD is the abnormal accumulation of α-synuclein, resulting in the formation of Lewy body in the dopaminergic neurons. These striking clinical features have focused efforts to understand the mechanisms responsible for neuronal death and reasons why dopaminergic neurons are differentially affected. In these neurogenerative microenvironment, Parkin protein, which functions as an E3 ubiquitin ligase, appears to rescue dying neurons from toxic and abnormal accumulations of cellular components despite the complexity of PD etiology.

iCP-Parkin as a superior disease-modifying anti-PD agent

An improved cell-permeable Parkin (iCP-Parkin) is our first-in-class Parkinson’s Disease (PD) drug candidate, which can penetrate the Blood Brain Barrier (BBB) and recover the damaged dopaminergic (DA) neurons. It is a Therapeuticmolecule Systemic Delivery Technology (TSDT) applied Cell-/Tissue-permeable Parkin recombinant protein. Like endogenous Parkin, iCP-Parkin can have cytoprotective action by recovering dysfunctional mitochondria through mitophagy and mitochondrial biogenesis. iCP-Parkin can reduce the accumulation of pathological α-Synuclein, thereby suppressing PD phenotypes. Currently, typical PD treatment such as L-Dopa employs symptom-relieving drugs replenishing the loss of Dopamine in brain, temporarily recovering patient’s abnormal motor function. Although the symptom maybe eased, it is not addressing

Therefore, the disease will get worse as time passes and side effects will be occurred.In contrast, iCP-Parkin has neuroprotection capability against PD-induced cellular stress,having a great potential as a disease-modifying therapy for PD biotherapeutics.

In AAV-α-Synuclein-induced PD mouse models, conducted in Severance Hospital and Cellivery, the behavior deficit was recovered with the treatment of iCP-Parkin, and the accumulation of pathological α-Synuclein was removed in the SN, with the recovery of tyrosine hydroxylase (TH) level.

Currently, in collaboration with Ildong Pharmaceutical CO., LTD, we are conducting preclinical R&D of iCP-Parkin at various global GROs and CMOs to move forward more rapidly to clinical development process.Also, Cellivery as a first-time grant recipient in South Korea, established iCP-Parkin research in support of Michael J. Fox Foundation (MJFF) for Parkinson’s Research (MJFF Program: No.14241. 2017. 07 ~ 2019. 03).

CP-BMP2

No Carrier! Only Simple Injection For Bone Regeneration!

Bone is the only organ that dynamically undergoes continuous tissue remodeling throughout life and is one of the few organs that retains regenerative potential on adult life. Severe damages in bone tissue require local supply of osteogenic growth factors of TGF-β family including bone morphogenetic proteins (BMPs) during regenerative process. Mainly, BMP2 plays an important role in skeletal development and bone formation. Clinical trials with recombinant human (rh) BMP2 protein-based approaches have been applied to promote the healing of severe fractures (e.g., long-bone non-union, tibial fracture implant) and spinal fusion. However, there are a few drawbacks with the use of rhBMP2. Due to short retention time and low tissue integration in a body, ? use of rhBMP2 is expensive with multiple or high-dose of treatment. In addition, rhBMP2 protein-based approaches have numerous side-effects (e.g., ectopic bone formation) at pharmacological dosage and sometimes requires surgical procedure, because it does not have an effective delivery method.

Cell-permeable BMP2 (CP-BMP2), our TSDT-applied rhBMP2, can be rapidly delivered into neighboring cells and tissues near the injured site by local injection, without a carrier/scaffold or any surgical procedure, and reside in the damaged bone tissue for a longer period, addressing rapid degradation and clearance rate issues that exist with rhBMP2. CP-BMP2 significantly activated Smad osteogenic signaling and induced ALP strongly. In addition, CP-BMP2 showed great persistency and enhanced stability in blood plasma. We also found that CP-BMP significantly promoted bone-regeneration (8 folds higher) in murine calvaria critical-sized defect and equine hind limb defect models.

Utilizing bio-better therapeutics with TSDT, we are developing CP-BMP2 as a next-generation osteogenesis agent to enhance local bone healing in a cost-/patient-friendly way.

CP-ΔSOCS3

The abnormal control of leptin, an adipocyte-secreted hormone controlling appetite, chronically causes morbid obesity as it accumulates excessive body fat.

On binding to leptin receptor (ObR) expressed in hypothalamic neurons, leptin evokes JAK/STAT signaling, and induces the expression of suppressor of cytokine signaling 3 (SOCS3) as a negative feedback regulator to maintain the homeostatic balance between food intake and fat accumulation. However, excessive leptin in obesity increases level of endogenous SOCS3 which promotes “leptin resistance” and disables the appetite-control by leptin. Due to this phenomenon, leptin-based therapeutic approach failed to effectively cure severely-obese patients, though it had previously been considered as an attractive anti-obesity strategy.

The goal of the project was to use advanced macromolecule transduction domain (aMTD) to deliver a competitive protein-based inhibitor to disrupt the binding of SOCS3 and ObR. Cell-permeable (CP) truncated SOCS3 recombinant protein (CP-ΔSOCS3) has been developed to overcome leptin resistance, and to investigate whether leptin-induced anti-appetite signals can be maintained for the treatment of severe obesity.

We observed that CP-ΔSOCS3 was efficiently delivered into cells and tissues includinghypothalamus by penetrating blood brain barrier (BBB), and directly interacted with ObR andenhanced leptin signaling in vitro and in vivo.

Diet-induced obese (DIO) mice treated with CP-ΔSOCS3 shows 26% of body weight decreased under the regular-fat diet (RFD) condition and 12% of body weight decreased under the high-fat diet (HFD) condition through regulating the expression of appetite regulatory marker and energy expenditure marker. In addition, CP-ΔSOCS3 improved fatty liver and reduced total cholesterol level of obese mouse. Furthermore, CP-ΔSOCS3 decreased the blood glucose level in DIO mice indicating that it may have therapeutic effect on type II diabetes. Therefore, we have successfully demonstrated the therapeutic applicability of CP-ΔSOCS3 fused to aMTD as a mechanism-specific anti-obesity agent to restore normal appetite as well as type II diabetes.

Currently, CP-ΔSOCS3 is in preclinical studies by performing process development, manufacturing, encapsulation and analytical method development at global CROs and CMOs.

iCP-Cre

Genetically engineered mouse models are useful tools for studying gene functionsin vivo.The discovery of Cre recombinase from bacteriophage P1 to induce DNA sequence-specific recombination in mammalian cells has achieved big advances in mouse models.

Applications involving Cre recombination have included conditional mutagenesis, gene replacement and chromosome engineering in mice, and conditional gene expression. However, process of generating Cre-mediated genetically engineered mouse models is expensive and time consuming. Also, the use of site-specific recombination in genetic studies is often hampered by difficulties expressing the recombinase enzyme in specific-type of cells and the desired developmental stage. Moreover, even conditional mutants induced by tissue-specific Cre expression may interfere with tissue development, thus, precluding later studies in terminally differentiated cells.

To overcome the limitation, the delivery of proteins with cell-penetrating peptides (CPP) intocells across impermeable cell membranes has been proposed as an attractive strategy to dealwith genetically engineered mouse models to define gene functions. The directly introducedcell-permeable recombinant protein is likely to be much easier, quicker, and less cost than othermethods, such as using Cre mouse or viral delivery.

For this purpose, we havenewly invented improved cell-permeable (CP) Cre recombinant protein fused to novel hydrophobic CPP, aMTD, to greatly increase their solubility, yield, and efficiency of membrane penetrating ability. iCP-Cre recombinant proteins induced high levels of recombination in a variety of cultured cells and all tissues examined in various genetically engineered mice (ROSA26-LSL-LacZ, ROSA26-LSL-EYFP, ROSA26nT-nG, SOCS3f/f etc.) following intravenous (IV) or local administration for whole-body or organ-specific (brain, liver, kidney etc.) recombination in vivo.

The use of protein transduction using cell-permeable Cre recombinase for genome engineering in animalsprovides a rapid and efficient tools to define gene function in mouse models.

iCP-RFs/Cas9

Terminally differentiated somatic cells can be reprogrammed to become induced pluripotent stem cells (iPSCs) by enforced expression of reprogramming factors (RFs) whichpromote self-renewal and render pluripotent cells leading to cellular differentiation. RFs contain 2 types of proteins, one for maintaining embryonic stem (ES) cells in a pluripotent state (OCT4, SOX2, and NANOG) and the other for promoting self-renewal and suppress cellular differentiation (CMYC, KLF4 and LIN28).

Based on this discovery, therapeutic approaches were developed by using autologous stem cells from patient-derived iPSCs without the ethical and graft rejection problems associated with using embryo-derived stem cells. Practically, the application of iPSCs to human regenerative medicine might require gene transfer to introduce RFs into somatic cells. Unfortunately, somatic cell reprogramming through gene transfer is relatively inefficient and is potentially mutagenic due to the genome integration of DNA-based expression vector. Other approaches that are not related toDNA-based expression vectors, such as, synthetic modified RNA and epigenetic regulation by chemical compounds are far from the practical application.

To overcome the limitation, we have newly invented improved cell-permeable RFsrecombinant proteins (iCP-RFs) fused to novel hydrophobic CPP, advanced macromoleculetransduction domain (aMTD), and solubilization domain (SD).

iCP-RFs induce stem cell-like colonies with high efficiency (0.01%~0.1%) and early colony formation with extension of self-renewal capacity and expression of stem cell-specific markers (OCT4, NANOG, TRA-1-60, TRA-1-81). Furthermore, by confirming that the stem cell-like colonies generated by iCP-RFs from stably differentiated teratoma of three germ layer, iCP-RFs have been shown to induce stem cells with complete pluripotent properties.

On the other hand, genome engineering is a technology for gene editing or repairingto recognize specific genetic sequence. This genome engineering technology is applicable tovarious fields, such as food, medical and research reagent. Especially, genome editingtechnology is used for therapeutic models to apply to therapy of genetic diseases.

The recent technology of CRISPR/Cas9 is powerful toolfor genome editing to repair disease-causing DNA mutations. However, a safe and efficient DNA delivery system are critical for guarantying the success of gene editing. Cell-permeable (CP) Cas9 with TSDT enables a simple treatment by gene editing with high cell-permeability. It is an innovative reagent that made it possible to be delivered into cells without DNA delivery. CP-Cas9 is increased in gene editing efficiency caused by intracellular transduction compared to previously used plasmid and mRNA system. These advantages of CP-Cas9 can be applied to gene modification as well as genetic research. CP-Cas9 also can be applied to stem cell therapy, which uses induced pluripotent stem cells (iPSC) for patients with genetic disorders.

Cas9 technology has been recently applied to disease-focused research through the production and characterization of patient-derived iPSCs from individuals with specific genetic diseases. The invention of induced iPSCs has greatly advanced translational research, especially with the generation of disease-derived human iPSCs. We believe CP-Cas9 will bring tremendous change forward in genetic transformation animal models, and even in stem cell research and therapy. Cellivery is open to out-licensing opportunities to institutions that want to begin research or development with CP-Cas9.

Ataxia is a neurodegenerative disease defined as an impaired voluntary coordination of muscle movement. Ataxia is mainly attributed to damages in the lesions of cerebellum, a part of the brain that is responsible for coordinating movement. Symptoms from the ataxia are serious and oftentimes cause weakness. Some types of ataxia related with genetic mutations can lead to an early death. Even though treatment for ataxia involves a combination of medication to reduce symptoms and to improve quality of life, these therapies have not shown substantial clinical improvement associated with neuronal loss.

CV-14 project is dealing with a special ataxia which is characterized by a monogenic autosomal recessive disease-causing a progressive neurogenerative disorder and cardiomyopathy, leading to an early death. CV-14 protein is known to play a key role in iron metabolism, particularly in iron-sulfur cluster (ISC) biogenesis and heme biosynthesis in mitochondria. A deficiency of CV-14 protein leads to an iron-sulfur cluster biosynthesis dysfunction, mitochondrial iron overload and oxidative stress in neurons and cardiac muscles. Protein replacement therapy that delivers proteins into cells across impermeable cell membrane has been proposed as an attractive strategy to deal with genetic diseases. For this reason, Therapeuticmolecule Systemic Delivery Technology (TSDT) applied cell-permeable CV-14 protein has been developed to be systemically delivered into damaged neurons and cardiomyocytes to protect from ataxia.

CV-14 project will be an effective therapeutic approach to strengthen neuronal function, which will greatly help patients who are suffering from ataxia.

iCP-NI

Sepsis is one of the top 5 diseases leading death worldwide and widely recognized as a clinical syndrome, resulting from an overwhelming, systemic inflammatory response.

Sepsis is occurred by excessive secretion of pro-inflammatory cytokine called ‘cytokine storm’, caused by microbial infection, severe injuries or surgical stresses. The global incidence of sepsis is 30 million and its overall mortality is more than 20 %, meaning that there are 6 million of death caused by sepsis every year. Besides, sepsis treatment is not adequately controlled by current antimicrobial therapies and supportive measures, thereby requiring new adjunctive treatments.

Previously, a polypeptide suppressing various pro-inflammatory pathways caused byendotoxamia has been developed by synthesizing the 1’st generation hydrophobic cell-penetratingpeptide (CPP), termed membrane translocating sequence (MTS) derived from the signal peptideof fibroblast growth factor 4 (FGF4), along with NF-κB-derived nuclear localization sequence (NLS).

Cell-permeable nuclear import inhibitor (CP-NI) increased survival rate of severe acute inflammatory animals by suppressing expression of pro-inflammatory cytokines such as TNF-α, IL-6 and IFN-γ. However, CP-NI was hard to manufacture mainly due to its low solubility, resulting in low clinical applicability. To address this limitation, improved cell-permeable nuclear import inhibitor (iCP-NI) has been developed by adopting advanced macromolecule transduction domain (aMTD) and demonstrated its superior stability and activity in sepsis animal models. iCP-NI successfully inhibits the activation of pro-inflammatory pathways and suppress secretion of pro-inflammatory cytokines. In addition, iCP-NI showed dramatically increased survivability in acute severe sepsis mouse models by protecting organ failure. Efficacy study with additional clinical animal models and safety study are on process to prove the powerful therapeutic applicability of iCP-NI.

As a result, this enhanced therapeutics, iCP-NI, can be developed as a novel, unique measures for severe lethal inflammatory syndromes such as septic shock.

Single-chain variable fragment (scFv) consists of the smallest functional antigen-binding domain of an antibody,in which variable heavy and variable light chains are joined together by a flexible peptide linker.

scFv retains the binding specificity of the parent antibody and offer several advantages over monoclonal antibodies.scFv displays improved pharmacokinetic properties, such as better tissue penetration, rapid blood clearance, and lowimmunogenicity which makes better therapeutic agents.

Although scFv has higher tissue penetration compared to antibodies, it still requires deliverytechnology for higher efficacy. Delivering scFv to targeting area is one of the main obstacles indeveloping scFv as a therapeutic candidate. To intracellularly localize scFv, many researchorganizations have tried variety delivery technologies such as nanoparticles, adeno-associatedvirus (AAV), and cell-penetrating peptides. Cellivery applied its technology TherapeuticmoleculeSystemic Delivery Technology (TSDT) to scFv and developed Cell-Permeable CV-16

Despite various advantages of scFv, it has obstacles to become a therapeutic agent due to the lack of a suitable means of delivery.CV-16 will provide efficient and effective delivery system to intracellularly localize scFv in targeted cells for its highest efficacy.CV-16 will expand applications of scFv which will ultimately help patients in need.

Antisense oligonucleotides (ASOs) are short, single-stranded oligodeoxynucleotide that interact with complementarymessenger RNA (mRNA) to prevent translation of a targeted gene into protein.

Thus, synthesizing an antisense oligonucleotide with the complementary sequence can be a drug which represent to work by binding to RNA. ASOs can reduce, restore, or modify protein expression through several distinct mechanisms by designing any sequences of RNA, so it can apply to treat a vast array of diseases.

Intracellular delivery of ASOs is recognized as the major barrier to effective ASOactivity within the target cell.

Therefore, to improve poor cellular uptake process, Cellivery used its technology Therapeuticmolecule Systemic Delivery Technology (TSDT) to improve cell-/tissue-permeability of ASOs. CP-17 can represent a new and valid approach to regulate the expression of disease-related genes and will greatly helpful for patients who are suffering from varying diseases.

The plasma membrane acts as an impermeable barrier, controlling the flow of proteins and other macromolecules in and out of cells.

However, Cellivery’s proprietary Therapeuticmolecule Systemic Delivery Technology (TSDT) allows functionally active macromolecules to rapidly transverse cellular membranes. The process utilizes specialized Cell-Penetrating Peptides (CPPs) that can be engineered into peptides, whole proteins, DNA fragments, and other bioactive substances, such as, drugs. With additional subcellular trafficking signals, transduced macromolecules can be guided to specific cellular locations, providing an effective way to influence intracellular protein function.

Indeed, TSDT platform has attracted vast interest and commentary by individuals outside of the Company for its potential use in a variety of applications. We anticipate that many activities throughout the biotechnology industry will involve licensing of Cellivery’s TSDT platform.

A series of papers published by Dr. Daewoong Jo and his colleagues have described a process, termed TSDT, to deliver biologically active proteins into mammalian cells and tissues. The technology provides a way to control biochemical processes in living cells quantitatively and under non-steady conditions. This sets the stage for the development of a new generation of protein-based therapeutics.

Since proteins function with specificity in the context of cellular biochemical pathways, protein-based therapies are expected to produce fewer side-effects than conventional small molecule-based drugs. TSDT exploits the ability of hydrophobic sequences termed macromolecule transduction domains (MTDs) to promote the uptake of peptides and proteins into mammalian cells. Consequently, MTD-fused recombinant proteins are said to be “cell-permeable (CP)”.

TSDT has proven to be superior to other protein transduction technologies. In particular, the use of HIV Tat and other basic sequences that promote unidirectional protein uptake via fluid-phase and adsorptive endocytosis. This sequesters most proteins in intracellular vesicles, which traps the protein cargo inside the cell, limiting cytoplasmic delivery, resulting in low bioavailability.

Finally, proteins modified with MTD sequences had significantly prolonged clearance times as compared to the identical proteins without an MTD sequence.
