Definitions
- a successful strategy for brain repair after stroke would deliver a molecule that stimulates angiogenesis and neural regeneration, reduces local inflammation, removes the barrier to cellular infiltration in the stroke site, and introduces a scaffold that can serve as a physical support onto which a new neuronal network can grow.
- biopolymer hydrogels have developed materials with extracellular matrix motifs that directly support survival and cell infiltration. The problem remains, however of the adverse effects of incorporating VEGF into the brain.
- Each dot in the plots represents one animal and p values were determined by One-way ANOVA with a Tukey's post-hoc test, with *, ** and **** indicating p ⁇ 0.05, p ⁇ 0.01 and p ⁇ 0.0001, respectively.
- FIG. 13F illustrates graphs showing infiltration distance and penetration angle in the stroke site at 2 weeks after stroke (10 days after gel transplantation).
- FIG. 13G illustrates fluorescent images of axonal neurofilaments (NF200) in and around the stroke site (*) at 16 weeks after gel transplantation. Scale bar: 100 ⁇ .
- FIG. 18C illustrates a graph illustrating the NF200 positive area a distance of 50 ⁇ from vessels.
- FIG. 18D illustrates fluorescent images of the peri-infarct astrocytic scar (GFAP) and BDA-traced neurons in the ipsilateral hemisphere of gel + hcV injected mice 16 weeks after gel transplantation.
- GFAP peri-infarct astrocytic scar
- FIG. 22A illustrates fluorescent images of vessels (Glut-1), astrocytic scar (GFAP), microglia (Iba-1) and axonal neurofilaments (NF200) in and around the stroke site (*) of gel + (hcV - nH) and LcV + nH) conditions, 16 weeks post-stroke. Scale bar: 100 ⁇ .
- FIG. 22D illustrates graphs showing the percentage NF200 area for the infarct and peri-infarct areas at 16 weeks after gel transplantation.
- FIG. 1 illustrates a cross-sectional view of a mammalian brain 10 that includes stroke cavity 12 formed therein.
- the delivery site is a stroke cavity 12 such as that illustrated in FIG. 1 that naturally forms after stroke.
- the clearance of debris in the lesion leaves a compartmentalized cavity 12 that can accept a large volume of the injectable therapeutic angiogenic material 20 described herein without further damaging the surrounding healthy parenchyma.
- This stroke cavity 12 is situated directly adjacent to the peri-infarct tissue area 14, the region of the brain that undergoes the most substantial repair and recovery, meaning that any therapeutic delivered to the cavity 12 will have direct access to the tissue target for repair.
- the injectable therapeutic angiogenic material 20 may also be transplanted in the peri-infarct area 14, or the brain surface 16.
- the therapeutic angiogenic material 20 is preferably s injected within fifteen (15) days of stroke onset, after day three (3) post-stroke to avoid the severe post-stroke inflammation and edema in the damaged brain.
- the specific localization of both the infarct (stroke cavity 12) and the peri-infarct areas are determined with three-dimensional intra-cerebral coordinates (x, y and z). While a syringe is illustrated as the delivery device 22 the therapeutic angiogenic material 20 may also be delivered using a catheter-based device or the like to deliver the injectable therapeutic angiogenic material 20 from a location outside the subject's brain to the stroke cavity 12.
- FIG. 4 illustrates one preferred embodiment of injectable therapeutic angiogenic material that was used in mouse brain studies.
- the injectable therapeutic angiogenic material illustrated in FIG. 4 is a hyaluronic acid hydrogel based on thiol-acrylamide Michael-type addition as described herein with a MMP labile peptide used as the crosslinker which resulted in a hydrogel that is both hyaluronidase degradable and MMP degradable, designed with a stiffness corresponding to the brain to reduce the local inflammatory response.
- FIG. 4 illustrates one preferred embodiment of injectable therapeutic angiogenic material that was used in mouse brain studies. The injectable therapeutic angiogenic material illustrated in FIG.
- Angiopoietin-2 (FIGS. 14A-14C) showed a significant increase in the peri-infarct area compared with the No gel and gel + Vs conditions. Angiopoietin-2 was significantly increased in the close vicinity of vessels (10 ⁇ ) in the gel + hcV condition compared with any other group, except of gel + nH.
- the nanoparticles were then dialyzed in 100 kD MWCO dialysis units for 12 hours and stored at +4C.
- the amount of heparin in the solution was determined by lyophilizing a small aliquot of the solution.
- a total concentration of 20 ⁇ g/ml VEGF was mixed with different concentrations of heparin nanoparticles ranging from 0.1 to 0.001 mg/mL to form different packing densities of VEGF onto the nanoparticle's surface, incubated overnight and exposed to a 365 nm wavelength UV light for 10 minutes to lock VEGF covalently to the surface.
- VEGF nanoparticles were then washed from excess with 0.05% Tween-20 in PBS, then with PBS, using a 100 kD MWCO dialysis units. The washes were collected and an Elisa and Dot blot were performed to estimate the amount of VEGF bound to nanoparticles by subtracting the washes to the total amount of VEGF mixed.

- Hyaluronic acid (60,000 Da, Genzyme, Cambridge, MA) was functionalized with an acrylamide groups using a two-step synthesis as previously described in Lei, S. et al, The spreading, migration and proliferation of mouse mesenchymal stem cells cultured inside hyaluronic acid hydrogels, Biomaterials 32, 39-47 (2011) and P. Moshayedi et al, Systematic optimization of an engineered hydrogel allows for selective control of human neural stem cell survival and differentiation after transplantation in the stroke brain, Biomaterials 105, 145- 155 (2016), which are incorporated herein by reference.
- an aliquot of the desired crosslinker (Ac-GCREGPQGIWGQERCG-NH2 [SEQ ID NO: 1], MMP-degradable or Ac-GCREGDQGIAGFERCG-NH2 [SEQ ID NO: 2], MMP- nondegradable) was dissolved in 0.3 M HEPES and added to the gel precursor solution.
- the precursor was loaded into the Hamilton syringe directly after mixing in the desired crosslinking peptide.
- mice were videotaped during walking and exploratory behavior in the cylinder, grid-walking, and pasta-handling tasks, two weeks before surgery to establish baseline performance levels. For all of the studies, animals were tested every four weeks after stroke at approximately the same time each day at the end of their dark cycle. Behavioral tests were scored by observers, who were masked to the treatment group in the study.

Abstract
Cette invention concerne une substance angiogénique injectable à visée thérapeutique comprenant un hydrogel à base d'acide hyaluronique à gélification in situ contenant une première pluralité de nanoparticules d'héparine-VEGF en grappes, où le VEGF est immobilisé sur les nanoparticules d'héparine, et une seconde pluralité de nanoparticules d'héparine nues, sans VEGF immobilisé sur les nanoparticules d'héparine. Selon un aspect de l'invention, la substance angiogénique injectable à visée thérapeutique est utilisée pour réparer un tissu ischémique chez un sujet (p. ex., mammifère). Pour traiter le sujet ou le patient, la cavité ischémique dans le tissu cérébral est localisée et la substance angiogénique à visée thérapeutique est injectée dans ladite cavité conjointement avec un agent de réticulation.
