Our Collaborations

At Coave, we welcome the opportunity to partner with leaders in genetic medicine, leveraging our proprietary next-generation ALIGATER™ platform to enable targeted delivery and enhanced gene transduction to improve the effectiveness of advanced genetic medicines for neurodegenerative and ocular diseases.

ABL is a pure play contract development and manufacturing organization (CDMO) specialized in the development and manufacturing of viral vectors for vaccine candidates, gene and cancer therapies.
We are collaborating with ABL to develop gene therapy manufacturing processes that enable us to control the development and manufacture of our pipeline products in an end-to-end manner.
Initially we will co-develop manufacturing technologies for AAV-based gene therapy products, after which we have an exclusive option to secure process development capacity and laboratory space within ABL’s facility. This will enable us to further develop and scale-up manufacturing technologies for our next generation AAV vectors and AAV-based products, including our ALIGATER platform.
ABL and Coave’s process development teams are working jointly in ABL’s state-of-the-art GMP facility in Lyon (France).
For more information see the press release announcing the collaboration here.

The Institute of Neurodegenerative Diseases (IMN) is a joint research unit associating the University of Bordeaux and the French National Centre of Scientific Research (CNRS). The IMN, established in January 2011, was founded by Dr Erwan Bézard to develop new therapeutic approaches for neurodegenerative diseases by facilitating translational research from the laboratory to the patient bed.
We are collaborating with IMN to identify new targets and pathways associated with neurodegeneration and leverage our expertise in gene therapy, including our ALIGATER™ platform to develop novel genetic medicines for neurodegenerative diseases. Our collaboration with IMN will initially focus on developing coAAV based gene therapy products for the targeted delivery of TFEB to deep brain structures for the treatment of various neurodegenerative disorders, focusing initially on Multiple System Atrophy (MSA) and idiopathic Parkinson’s disease (PD) (a-synucleinopathies).
IMN will be responsible for carrying out in vivo studies to validate the concept of gene therapy for TFEB delivery in models of MSA and PD. The collaboration aims to generate further in vivo proof of concept data and enable the selection of therapeutic candidates to enter Investigational New Drug (IND) enabling studies.
For more information see the press release announcing the collaboration here.

Technology

Our ALIGATER™ (Advanced Vectors-Ligand Conjugates) platform leverages the wealth of knowledge around commonly used and well-characterized AAV vectors and non-viral Lipid Nanoparticle (LNP) vectors with a proprietary chemical conjugation technology to produce novel genetic medicines for neurodegenerative and ocular diseases.

Meet ALIGATER™

Our proprietary platform for a novel class of gene therapies that are effective, safe, and applicable to rare as well as prevalent diseases.
Our core technology is based on functionalizing AAV or LNP, by conjugation of rationally designed ligands onto vectors surface, improving tissue targeting and efficient payload delivery.
Conjugation of chemical ligands to specific amino acids of the AAV capsid
50+ coAAV variants generated
One-step process downstream of AAV manufacturing; applicable to clinical candidates
In vivo cross-species superiority validated (rodent & NHP)
AAV-Ligand conjugation technology is altering the biology of AAV capsids through several potential mechanisms:
BIODISTRIBUTION

Site-specific conjugation onto capsid proteins enables altering of extracellular capsid sequestration, by blocking the binding of the AAV capsid to extracellular motifs.

CELL AND TISSUE TARGETING

Ligands are rationally designed to improve cell and tissue targeting, based on defined ligand-receptor interactions.

INTRACELLULAR

Site-specific conjugation of capsid proteins leads to improvement of intracellular AAV capsid trafficking and payload delivery to the nucleus.

EVADE IMMUNE RESPONSES

Ligand conjugation reduces coAAV exposure to immune reaction and neutralizing antibodies.

Preclinical experiments have demonstrated superiority of coAAVs over best-in-class AAV serotypes in terms of transduction efficiency and tissue distribution.
As a result, our ALIGATER technology offers the potential to generate coAAV based gene therapies with improved delivery to target tissue, at lower doses, thus limiting systemic and local toxicity.

Manufacturing

A key element of our strategy is to develop a robust manufacturing process for our next-generation gene therapies.
We have a growing team of in-house experts who have made significant advances in process and product development for our ALIGATER™ platform. Core elements of these processes are protected by patents and proprietary know-how.
We are collaborating with ABL, a CDMO with proven expertise in developing and executing GMP manufacturing of viral vectors for gene therapy products, to co-develop manufacturing technologies for AAV-based products, including those deriving from our ALIGATER platform.
Coave and ABL’s process development teams are working together in ABL’s state-of-the-art GMP facility in Lyon (France), which will give us the flexibility and capacity to manufacture high-quality gene therapy products at large scale.

Pipeline

We are developing a diversified pipeline of novel genetic medicines for neurodegenerative diseases and ocular diseases, by harnessing our ALIGATER™ technology to enable precise and safe delivery of low dose gene therapy. We are targeting genetically and non-genetically defined diseases by correcting, activating or regulating key functions and pathways involved in the pathogenesis of these diseases.

Neurodegenerative Diseases

Targeting Protein Degradation by Activating the Autophagy Lysosomal Pathway

The misfolding and accumulation of disease-related proteins are common hallmarks of several neurodegenerative diseases. As examples, beta-amyloid and tau in Alzheimer’s disease, alpha-synuclein (aSyn) in Parkinson disease and related disorders, and mutated huntingtin in Huntington’s disease, are shown to contribute to disease progression and neurodegeneration.

Pathological accumulation of aSyn is the common distinguishing trait amongst the group of brain disorders known as synucleinopathies, which include Parkinson’s disease (PD), Dementia with Lewy bodies (DLB), and Multiple System Atrophy (MSA). These disorders progressively develop neuronal and glial inclusions enriched with misfolded, phosphorylated and insoluble aSyn.

Over the past decade, several treatment strategies directly targeting aSyn have been evaluated in preclinical and clinical studies. These diverse approaches include removal of aggregated aSyn with passive or active immunization or by expression of vectorized antibodies, modulating kinetics of misfolding with small molecule anti-aggregants, lowering aSyn gene expression by antisense oligonucleotides or inhibitory RNA.

More recently, several new approaches aiming to harness the natural cellular machinery for degradation of toxic protein aggregates, including aSyn, have been investigated.

The autophagy lysosomal pathway (ALP) is a central cellular pathway enabling the degradation of toxic protein aggregates. Key factors of the ALP, such as Glucocerebrosidase (GBA1) and Transcription Factor EB (TFEB), have been shown to play important roles in aSyn clearance mechanisms (Figure X).

At Coave, using our ALIGATER™ platform, we have generated coAAV based gene therapy delivering a safe, low dose of GBA1 and TFEB precisely in the targeted structures of the central nervous system (CNS), aiming to activate or restore the macro-autophagy and lysosomal functions to eliminate or prevent the accumulation of toxic protein aggregates associated with neurodegenerative disease. 

Parkinson’s Disease

Parkinson’s disease (PD) is a severe and progressive neurodegenerative disorder that affects more than seven million people worldwide.

Population-based genetic studies have recently identified several causative and risk genes for PD. Many of these genes are involved in the normal functioning of lysosomes, a cell organelle containing enzymes responsible for degrading biomolecules.

The GBA1 gene encodes the lysosomal enzyme beta-glucocerebrosidase (GCase), which is needed for the disposal and recycling of glycolipids — a type of cellular lipid component that is known to accumulate with aging. Mutations in the GBA1 gene lead to a deficiency of GCase and are associated with earlier onset of PD, with more severe symptoms, and increased likelihood of progression to dementia. Certain mutations in GBA1 reduces the functionality of GCase, which may favor toxic build-up of alpha-synuclein fibrils resulting from the accumulation of glycolipids.

There are currently no approved therapies that modify the course of PD or the underlying pathological process.

CTx-GBA1: an optimized gene therapy for treating GBA1 associated diseases

Our gene therapy candidate, CTx-GBA1, utilizes a coAAV vector to deliver a gene sequence encoding functional GCase enzyme. CTx-GBA1 has been optimized for improved transduction and distribution of the GBA1 gene in the key structures (basal ganglia) of the brain involved in Parkinson’s disease and related disorders.

Multiple System Atrophy and other a-synucleinopathies

The a-synucleinopathies, Multiple System Atrophy (MSA), Parkinson’s disease (PD) and Lewy Body Dementia (LBD), are characterized by aggregates of a-synuclein, associated with impairment of the autophagy-lysosomal pathway. TFEB is a master regulator of the autophagy lysosomal pathway, a central cellular pathway controlling the degradation of toxic protein aggregates. Overexpression of TFEB via gene therapy demonstrates potential to reduce and prevent the accumulation of toxic protein aggregates1.

Coave, in collaboration with the Institute of Neurodegenerative Diseases (IMN), is using its ALIGATER platform to generate coAAV based gene therapy products to target the delivery of TFEB in deep brain structures to treat various neurodegenerative disorders, starting first with a-synucleinopathies.

A paper2, authored by eminent scientists at IMN, including Erwan Bézard, IMN and INSERM Research Director and world-renowned Dr Andrea Ballabio, Scientific Director, Telethon Institute of Genetics and Medicine (TIGEM), demonstrated effective delivery of TFEB AAV-based gene therapy in disease models of MSA and PD.

CTx-TFEB: optimized gene therapy to treat a-synucleinopathies

Our gene therapy product candidate, CTx-TFEB, utilizes a coAAV vector to deliver a gene sequence encoding functional TFEB transcription factor. CTx-TFEB has been optimized for improved transduction and distribution of the TFEB gene in the key structure of the brain involved in MSA and PD.

Ocular diseases

Inherited Retinal Dystrophies

Inherited retinal dystrophies are rare ophthalmic pathologies that can be divided into two groups:

  1. Pigmentary retinopathies, which include retinitis pigmentosa (RP) and Leber congenital amaurosis
  2. Macular dystrophies

Retinitis pigmentosa is the most common form of inherited retinal dystrophy representing 50% of all retinal dystrophies.

While multiple genes are implicated in each of these groups, within each patient or family, only one causative gene is involved.

PDE6b Inherited Retinal Dystrophy (IRD)

PDE6b RP is an inherited retinal dystrophy that leads to blindness by midlife and is characterized by the progressive loss of photoreceptors, with or without the loss of retinal pigment epithelium cells.

It is caused by mutation of the PDE6b gene resulting in dysfunctional Rod PDE6, an enzyme found in rod outer segments that plays a key role in the phototransduction cascade in rods (the process by which light is converted into electrical signals). Dysfunction of the PDE6 protein, and in particular its PDE6ß subunit, ultimately leads to death of rod photoreceptor cells, then cone photoreceptor cells, leading to blindness.

Mutation of PDE6b is one of the most prevalent human mutations within autosomal recessive RP and accounts for 2-4% of RP cases.

There are currently no approved treatments for PDE6b RP.

CTx-PDE6b: A clinical stage AAV based gene therapy for treating PDE6b IRD

CTx-PDE6b is an AAV5 based gene therapy designed to deliver a full-length non-mutated copy of the functional human PDE6b gene into the subretinal space, where it rapidly induces robust transgene expression and synthesis of functional PDE6b proteins in photoreceptive rods and cones. By effectively providing these cells with a functional protein, CTx-PDE6b may significantly delay or halt retinal degeneration in PDE6ß-deficient patients.

CTx-PDE6b is currently in Phase I/II clinical trials.

A description of the protocol can be found on clinicaltrials.gov
