How engineered protein helps Nanomedicine againts Cancer

The use of protein nanoparticles as biomaterials have been rising in recent years due to their characteristics: high biocompatibility, structural versatility, biodegradability and plasticity of design. We can later incorporate peptide ligands for specific targeting as fusion proteins and use these nanoparticles for targeted nanomedicine.

However, not all proteins can be used as scaffolds for targeted drug delivery, as they need to meet certain criteria. First, it is crucial that the proteins used as a scaffold allow site-specific drug conjugation. The stability and proteolysis resistance of these proteins is also important to remain assembled during the bloodstream circulation. In addition, the scaffolds must be biologically neutral, meaning that they should not interact with other human proteins that interfere with their capacity to reach and specifically deliver their cargo. The lack of immunogenicity of these proteins is also desired to avoid immune system recognition. And, ideally, the proteins used as a scaffold should not have post-translational modifications to ensure that they fold equally in both prokaryotic and eukaryotic cell factories for production.

The scaffolds that have all these properties have a better chance to both achieve a proper biodistribution and to successfully deliver their cargo molecules into the target cells. The Green Fluorescent Protein (GFP) satisfy most of the desired characteristics for a scaffold. Moreover, its intrinsic fluorescence allows the tracking of the protein distribution and intracellular localization both in vitro and in vivo.

The use of GFP as a protein scaffold for targeted drug delivery has been extensively studied in our group. We have been able to deliver cytotoxic drugs through our patented platform for targeted delivery. This platform consists of a cationic peptide ligand (T22) and a hexa-histidine peptide that act as self-assembling tags. T22 is a CXCR4 ligand that enables a targeted delivery to CXCR4⁺ cells, a receptor that is overexpressed in metastatic cancer cells. We have demonstrated previously in an in vivo model that more than the 85% of the administered product was accumulated in the tumor and that we could efficiently conjugate Floxuridine (a genotoxic antimetabolite) to our T22-GFP-H6 nanoparticles, resulting in a strong anti-metastatic activity.

Despite these very promising results, GFP is an exogenous protein from Aequorea victoria and, consequently, triggers an immune response, which limits its clinical use. Thus, we needed to find a human protein that matches the exceptional properties of GFP as a protein scaffold. Fortunately, a non-fluorescent GFP-like protein has been described in humans and it corresponds to one of the three globular domains of Nidogen, a structural protein that binds to collagen IV, laminin and perlecan with high affinity. The globular domain G2 has a beta-barrel structure with a central alpha-helix that folds very similarly to the GFP, despite that these proteins share very low sequence identity. Notably, this domain does not have post-translational modifications that could interfere with its production and folding in prokaryotic cells.

However, perlecan and collagen IV binding sites have been reported within this G2 domain. Therefore, we needed to selectively mutate these binding sites in order to assure the biological neutrality of the nanoparticles. After a thorough structural analysis, we incorporated four different mutations to engineer a biologically neutral product that was named HSNBT. There were no differences detected between the wild-type G2 domain and the engineered HSNBT protein regarding the predicted structural epitopes, which suggested that the introduced mutations would not generate immunogenicity.

In order to validate the new scaffold, we used the above-mentioned patented platform with T22 and the hexa-histidine tag, replacing GFP for the new HSNBT scaffold. First, we characterized the resulting nanoparticles and we determined, both by Dynamic Light Scattering (DLS) and Scanning Electron Microscopy (SEM), that they had a size of around 10 nanometers. Then, we observed that the T22-HSNBT-H6 nanoparticles were internalized effectively by CXCR4⁺ cells. This specificity was corroborated when we used a CXCR4 antagonist (AMD) and we saw a notable decrease of their internalization. Then, we successfully conjugated floxuridine to the nanoparticles (T22-HSNBT-H6-FdU) through the free lysine-amino groups of the protein and we demonstrated that the nanoconjugates had a potent cytotoxic effect in CXCR4⁺ cells.

Once we have validated these nanoconjugates in vitro, we tested them in a colorectal cancer mouse model. Notably, we saw an important tumor growth inhibition after several doses of these nanoconjugates. The inhibitory effect was slightly higher when using the new scaffold than with GFP. We also saw a significant increase in cell death bodies and caspase-3 activation in the tumor after the treatment with the nanoconjugates. Again, the effect was more potent with HSNBT as a scaffold than with GFP. Remarkably, the treatment did not result in any histological toxicity and there were no differences between the weight of the treated mice when compared to the untreated mice.

This technology is protected by 3 patents: The ligand to enter CXCR4+ cells (WO2012/095527), the nanoconjugates (EP17382461.6) and the human scaffold protein HSNBT, (EP19383201), all three licensed to Nanoligent SL.

All in all, these results confirm that the G2 domain of nidogen can be used as a protein scaffold for targeted drug delivery. Its performance both in vitro and in vivo not only matches the observed with GFP, but it is even more efficient than GFP when conjugated with floxuridine. Therefore, the engineered HSNBT protein shows a very exciting potential to be used in the development of protein-based nanomedicines.

Wide representation of NANBIOSIS research in NALS 2022 and best Oral Presentation to Eloi Parladé

During the last 27-29 April, the 3rd International Conference on Nanomaterials Applied to Life Sciences 2022 (NALS 2022) has taken place in the Excellence Campus of Universidad de Cantabria in Santander (Spain), organized by the University of Cantabria and Institute Valdecilla-IDIVAL.

NALS 2022 has been a multidisciplinary conference series sharing new results and ideas in the fields of biosensors, lab on a chip, drug delivery nanopharmacy. nanobiotechnology, intelligent nanomaterials, magnetic materials, nanotoxicity, antimicrobials, novel applications of 3d bioprinting and nanoimaging.

NANBIOSIS has been represented at this edition by members of several of its units, among them we must highlight the set of four oral communication presented by members of the Nanobiotechnology group-Unit 1 of NANBIOSIS “Protein Production Platform (PPP)”, from CIBER-BBN and IIB-UAB the talks were delivered by:

Eloi Parladé: “Development of ion-dependent microscale secretory granules for nanomedical applications”

Carlos Martínez-Torró: “Design of a human GFP-like protein scaffold for targeted nanomedicines”

Eric Voltá Durán: “Antitumoral nanoparticles with multiple activities, a close reality”

Jan Atienza-Garriga: “Characterization of protein-only NPs containing amps and analysis of their protection with liposomes and micelles”

They summarized a wide area of the team activities on the design of protein-based protein materials for clinical uses, produced by means of diverse types of cell factories. In particular, antimicrobial peptides, cytotoxic proteins with antitumoral targeting and drug-carrying scaffold proteins are engineered to confer self-assembling properties as either microparticles or nanoparticles, that can be further functionalized with chemical drugs through covalent binding. Microparticles are of special interest as they can be used as slow drug delivery systems for nanostructured drugs upon subcutaneous administration. Alternatively, nanoparticles can be also presented as embedded in liposomes or other micellar structures that stabilize them for enhanced performance.

Three NANBIOSIS units supported the presented research, which has been executed in a highly cooperative way: namely U1 (Protein Production Platform), led by Tony Villaverde U18 (Nanotoxicology), led by Ramón Mangues and U29 (Oligonucleotide Synthesis Platform), led by Ramón Eritja.

Among all the excellent contributions by the team, it is worthy to stress that the prize for the best Oral Presentation was granted to Dr Eloi Parladé.

Other talk by researchers from NANBIOSIS were “Antioxidant-loaded polymeric NPs prepared by nano-emulsion templating for the management of neurological diseases” by Santiago Grijalvo, from NANBIOSIS U12 and “Exploiting GSH oxidation with nanocatalysts to promote cancer cell death” by Javier Bonet-Aletá from NANBIOSIS U9

On the other hand, Jesús Santamaría, Scientific Director of NANBIOSIS U9 was a Keynote Speaker in the Conference with the talk: “A change of paradigm in cancer therapy? Using catalysts to make drugs inside the tumor, rather than trying systemic chemotherapy”

NALS 2022 has been an excellent conference, with presentations covering a wide range of topics in nanomaterials for health, and a great opportunity for our researchers, especially for young’s, to let know their collaborative work, as well as make new connections on common research interests, thanks to the good socializing opportunities afforded by the scheduling of the organization conference.

Fabry Desease in the Rare Disease Day: A New Hope

WHY DO CELEBRATE TODAY THE INTERNATIONAL #RareDiseaseDay?

29 of February is a ‘rare’ date and February, a month with a ‘rare’ number of days, has become a month to raise awareness about rare diseases and their impact on patients’ lives. Since 2008 thousands of events happen every year all around the world and around the last day of February with the aim of improving equity and reducing stigmatization for people who live with more than 6,000 rare diseases.

WHAT ARE RARE DISEASES

Rare diseases are pathologies or disorders that affect a small part of the population (less than 5 per 10,000 inhabitants) and generally have a genetic component. They are also known as orphan diseases.

Diseases present a series of particular symptoms, and it is very difficult to diagnose what their true cause is. These disorders or alterations that patients present must be evaluated by a specialist, depending on each case.

Today 5% of the world population suffer from them. This translated into numbers, corresponds to approximately 300 million affected.

A patient with a rare disease waits an average of 4 years to obtain a diagnosis, in 20% of cases it takes 10 or more years to achieve the proper diagnosis.

ORPHAN DRUGS

To combat this disease, patients need to be treated with so-called orphan drugs. They serve to prevent and treat pathology. Its composition is based on biotechnological compounds whose manufacture is very expensive and not profitable for companies. For this reason, cooperation of governments is needed as well as financial incentives to encourage pharmaceutical companies to develop and market medicines to make these treatments accessible to a greater number of people.

FABRY DISEASE

Fabry is one of the rare diseases that currently lack a definitive cure. Symptoms may include episodes of pain, especially in the hands and feet (acroparesthesias); small dark red spots on the skin called angiokeratomas; decreased secretion of sweat (hypohidrosis); opacity of the cornea (cataracts) and hearing loss. Internal organs such as the kidney, heart, or brain may be involved, resulting in progressive kidney damage, heart attacks, and strokes.

Fabry disease is a lysosomal storage disease arising from a deficiency of the enzyme α-galactosidase A (GLA). The enzyme deficiency results in an accumulation of glycolipids, which over time, leads to cardiovascular, cerebrovascular, and renal disease, ultimately leading to death in the fourth or fifth decade of life. Currently, lysosomal storage disorders are treated by enzyme replacement therapy (ERT) through the direct administration of the missing enzyme to the patients.

“SMART 4 FABRY” EUROPEAN PROJECT

CIBER-BBN, through the researcher Nora Ventosa has coordinated the european project “Smart-4-Fabry” developed during 2017-2021, the proyect was undertaken by a consortium formed by ten partners, including private companies and public institutions in Europe and Israel, with a Horizon 2020 financial programme by the European Commission (H2020-NMBP-2016-2017; call for nanotechnologies, advanced materials, biotechnology and production; Proposal number: 720942-2).

In view of their advantages as drug delivery systems, liposomes are increasingly being researched and utilized in the pharmaceutical, food and cosmetic industries, but one of the main barriers to market is their scalability.

Depressurization of an Expanded Liquid Organic Solution into aqueous solution (DELOS-susp) is a compressed fluid-based method that allows the reproducible and scalable production of nanovesicular systems with remarkable physicochemical characteristics, in terms of homogeneity, morphology, and particle size. The objective of this work was to optimize and reach a suitable formulation for in vivo preclinical studies by implementing a Quality by Design (QbD) approach, a methodology recommended by the FDA and the EMA to develop robust drug manufacturing and control methods, to the preparation of α-galactosidase-loaded nanoliposomes (nanoGLA) for the treatment of Fabry disease.

Through a risk analysis and a Design of Experiments (DoE), researechers obtained the Design Space in which GLA concentration and lipid concentration were found as critical parameters for achieving a stable nanoformulation. This Design Space allowed the optimization of the process to produce a nanoformulation suitable for in vivo preclinical testing.

The new nanoformulation developed by Smart4Fabry for the treatment of Fabry disease achieved the ODD (Orphan Drug Designation) by the European Commission. The new nanomedicine is more effective and has a better biodistribution than the current treatments, based on enzyme replacement. The new nanomedicine is based on a nanovesicle that protects the enzyme and achieves a better cell internalisation, thus reducing the doses needed, the total cost and improving the quality of patients.

Four units of NANBIOSIS participated in the project:

– U1 Protein Production Platform (PPP) led by Neus Ferrer and Antony Villaverde at IBB-UAB for the production and purification in different expression systems for R&D purposes.

– U3 Synthesis of Peptides Unit led by Miriam Royo at IQAC-CSIC performed all the chemical process of the Smart-4-Fabry project, i.e. design and synthesis of peptides used as targeting ligands in the nanoliposome formulation.

– U6 Biomaterial Processing and Nanostructuring Unit led by Nora Ventosa at ICMAB-CSIC developed tasks related to the manufacture of the nanoliposome formulation of GLA enzyme and the physico-chemical characterization (this unit counts with plants at different scales, from mL to L, which allow process development by QbD and process scale-up, as well as instrumental techniques for assessment of particle size distribution, particle concentration, particle morphology and stability, and Z-potential) .

– U20 In Vivo Experimental Platform led by Ibane Abásolo at VHIR carried out the non-GLP preclinical assays of the project (in vivo efficacy, biodistribution and tolerance/toxicity assays).

PHOENIX: OPEN INNOVATION TEST BED

Researchers of CIBER-BBN and NANBIOSIS, led by Nora Ventosa, are currently participating in another european project, PHOENIX “Enabling Nano-pharmaceutical Innovative Products” in the framework of which this novel nanomedicine developed under the Smar4Fabry project and designed as Orphan Drug by the EMA, will be scaled-up and manufactured under GMP to enable its clinical testing.

The activity of Peptide T22 as antimicrobial drug opens new possibilities for the local control of bacterial infections related to tumors

Researchers of NANBIOSIS Units 1 and 18, from CIBER-BBN at the Institut de Biotecnologia i de Biomedicina (IBB-UAB) and the Institut de Recerca Sant Pau (IIB-Sant Pau) presents the finding of a significant antimicrobial activity in the targeting peptide T22, which is used for antitumor therapy directed against CXCR4 + stem cells, with clinical interest in more than 20 types of human cancer, including colorectal cancer.

The study describes how said activity has a significant effect on several bacterial species of clinical importance: “we have detected antimicrobial activity associated with T22 and inhibition of biofilm formation on Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa, explains Antonio Villaverde, one of the coordiantors of the study . The researcher adds that “the T22 peptide does not show cytotoxicity on mammalian cells or hemolytic activity and is active when it is shown in protein nanoparticles through genetic fusion.”

For the develiopment of this research protein production was partially performed by the unit 1 of the ICTS NANBIOSIS, Protein Production Platform (PPP).

In short, the discovery of T22 as AMP is of interest, not only because of its addition to the catalog of antibacterial drugs, but its clinical uses could allow its combined and multivalent application in complex clinical conditions, such as colorectal cancer, which could benefit from the synchronous destruction of cancer stem cells and local bacterial biofilms.

The stable collaboration between the NBT group led by Esther Vazquez and Antonio Villaverde, the GOA group led by Ramón Mangues and the spin-off of the UAB Nanoligent, develops systemic targeted therapies using T22 to functionalize different types of cytotoxic nanoparticles, with which the destruction of metastatic stem cells and the consequent reduction in the number of metastases. “The dual activity of T22 as a targeting agent and as an antimicrobial drug may offer a new local treatment route, through which bacterial infections related to the development and progression of tumors are controlled locally,” the authors conclude.

The CIBER-BBN transfer program through its call for transfer and valorization projects has been designed to promote the transfer to the industrial sector of scientific or technological results derived from the research carried out by the CIBER-BBN groups. These transfer projects will make it possible to support the commercialization of said results, since there is a company that has shown interest in them and that provides at least, the same financing than CIBER-BBN for their achievement.

The call for valorisation projects is in its fourth edition, having already financed a total of fourteen projects.

A more effective nanomedicine has been developed for the treatment of Fabry rare disease.

28 February: International Rare Disease Day

This is one of the major achievements of the European Smart4Fabry project, which is now coming to an end after four years of work.
The results have been made possible by nanotechnology and the approach developed could be applied to other drugs in the future.
The new drug improves on current treatments and helps reduce costs and improve patients’ quality of life.

Barcelona, 26 February 2021.- The advance of nanomedicine opens up new possibilities in the development of drugs, such as the one recently developed for the rare disease Fabry, with improved efficacy compared to existing authorised treatments.

Thus, the European Smart4Fabry project has come to an end with one of the best results possible: the designation of a new orphan drug by the European Commission and the possibility of making progress in the treatment of Fabry, a rare disease that is estimated to affect approximately 2.6 out of every 10,000 people in the EU.

It is a chronic debilitating disease due to recurrent episodes of severe pain that is difficult to control with conventional analgesics, and it is life-threatening due to renal failure and associated cardiovascular and cerebrovascular complications.

“With this designation we have made a major achievement, not only for Fabry patients, but also for other pathologies that can benefit from this same approach, made possible by nanotechnology,” explained Nora Ventosa, Scientific Director of NANBIOSIS Unit 6 Biomaterial Processing and Nanostructuring Unit of CIBER-BBN and ICMAB-CSIC who coordinated the project.

Need for new treatments for the disease

This disease, also known as Anderson-Fabry disease, represents the most common lysosomal storage disorder. It is caused by an absence or deficiency of the enzyme α-galactosidase A (GLA), which results in the lysosomal accumulation of globotriaosylceramide (Gb3) and its derivatives in the lysosomes of a wide variety of tissues, responsible for the clinical manifestations. Current treatments consist of intravenous administration of the GLA enzyme, but have limited efficacy and poor biodistribution.

The drug that has been developed is a new nanoformulation of GLA (nanoGLA) that improves efficacy compared to the reference treatment with non-nanoformulated GLA. “The third-generation liposomal product we have developed in the project has demonstrated, at preclinical level, improved efficacy, compared to authorised enzyme replacement treatments, demonstrating that the strategy of supplying the affected cells with the GLA enzyme via the smart nanoliposome is highly successful”, explained Ibane Abasolo, Scientific Coordinator of NANBIOSIS U20 of CIBER-BBN and VHIR, who is responsible for the efficacy studies in the project.

The nanoGLA product was obtained using DELOS^TM formulation technology, an innovative platform for the robust production of nanomedicines in an efficient and sustainable manner.

The Committee for Orphan Medicinal Products, the European Medicines Agency’s (EMA) committee responsible for recommending orphan designation of medicines for rare diseases, has considered these results to have a clinically relevant advantage over current enzyme replacement therapies.

The designation of orphan drug, in addition to recognising the significant benefit of the new nanomedicine over products already licensed for Fabry disease, has important implications for the translation of the new therapeutic product from bench to bedside.

Those responsible for these results, including several CIBER-BBN groups, highlight that the new formulation helps to improve treatments, reduce costs, and improve the quality of life of Fabry patients.

Interdisciplinarity and public-private collaboration

The Smart4Fabry project has been running since 2017 thanks to European funding of €5.8 million, from the Horizon 2020 programme. This was possible thanks to the collaboration of several CIBER-BBN groups and NANBIOSIS Units at the Institute of Materials Science of Barcelona (ICMAB-CSIC) with the abouve mentioned NANBIOSIS Unit 6, the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC) with NANBIOSIS Unit 3 of
Synthesis of Peptides Unit, led by Miriam Royo, the Vall d’Hebron Research Institute (VHIR) with NANBIOSIS Unit 20 and the Institute of Biotechnology and Biomedicine of the Autonomous University of Barcelona (IBB-UAB) with NANBIOSIS Unit 1 Protein Production Platform (PPP), whose work in this project was led by José Luis Corchero. It has also been necessary to contribute knowledge from different academic and business disciplines.

The project consortium also includes public institutions such as the University of Aarhus (Denmark), Technion Israel Institute of Technology (Israel) and Joanneum Research (Austria); and the companies Biokeralty (Spain); Nanomol Technologies SL (Spain); BioNanoNet (Austria), Drug Development and Regulation SL (Spain), the Covance Laboratories LTD group (UK) and Leanbio SL (Spain), which have provided the necessary expertise in nanotechnology and biotechnology, physicochemical characterisation, in vitro and in vivo biological evaluation, formulation and grading of nanomedicines, and pharmaceutical development and production under the guidelines of regulatory agencies.

CIBER and CSIC, promoters of orphan drugs

Orphan Drug Designations (ODDs) seeks to facilitate the arrival of treatments for rare diseases on the market. Several incentives are associated with ODDs, such as market exclusivity, fee reductions and specific scientific advice.

To date, CIBER has promoted eleven orphan drugs designated by the EMA, mainly from the thematic area of Rare Diseases (CIBERER), this being the first from CIBER-BBN.

On the other hand, this is the fourth ODD that the CSIC has obtained, and the first time it refers to a nanoformulated drug.

Orphan drug designation by the European Medicines Agency has several advantages, such as receiving a commercialisation authorisation for 10 years during which similar products cannot be commercialised, the availability of free or low-cost scientific advice and support protocols, and exemption from designation fees. In addition, entities developing orphan drugs have access to specific grants from the European Union and member states’ programmes.
