Description

TECHNICAL FIELD

This invention relates to the field of pharmaceutical formulation and methods of treating inflammatory and/or pain conditions.

BACKGROUND

Non-steroidal anti-inflammatory drugs (NSAIDs) are a class of small molecule drugs designed to reduce much of the inflammation and pain experienced by subjects having an inflammatory and/or pain condition. Cyclooxygenase-1 and Cyclooxygenase-2 (also called prostaglandinendoperoxidase synthase 1 and 2, respectively) are enzymes that are responsible, in part, for some of the inflammation and pain experienced in inflammatory disorders (eMed Expert website, www.emedexpert.com/compare/nsaids.shtml). Currently, subjects having an inflammatory and/or pain condition are orally administered an NSAID. Some subjects experience side effects from the oral administration of NSAIDs including, for example, gastritis, gastric ulceration, renal insufficiency, indigestion, diarrhea, nausea, headaches, and chest pain (Brune, Curr. Med. Res. Opin. 23(12):2985-2995, 2007). Oral administration of high doses of NSAIDs can also result in increased risk of stroke in the subject and an increased risk of having a negative affect on the cardiovascular system of a subject.

Silk fibroin hydrogels have previously been used as a delivery vehicle for monoclonal antibodies (Guziewicz et al., Biomaterials 32(10):2642-2650, 2011). Silk fibroin hydrogel is also known to be biodegradable and biocompatible in mammals (Guziewicz et al., Biomaterials 32(10):2642-2650, 2011).

SUMMARY

The present invention is based, at least in part, on the discovery that formulation of a benzenesulfonamide-containing non-steroidal anti-inflammatory drug (NSAID) into a composition (e.g., a gel, e.g., a hydrogel) including silk fibroin results in a surprisingly increased duration of sustained delivery of a therapeutically effective amount of the benzenesulfonamide-containing NSAID in a subject following administration of the composition (e.g., gel) to the subject. In view of this discovery, provided herein are compositions (e.g., gels, e.g., hydrogels) that include a benzenesulfonamide-containing NSAID, silk fibroin, and a gelling agent (e.g., any of the gelling agents described herein or known in the art), where the composition releases a therapeutically effective amount of the benzenesulfonamide-containing NSAID over a period of 10 days to about 200 days when incubated in phosphate buffered saline (PBS), 2% Tween-80 in PBS, or 2% Tween-80 and 0.05% sodium azide in PBS at 37° C. Also provided are compositions that include a gel provided herein, kits that include any of the compositions provided herein, and methods of making any of the compositions (e.g., gels) provided herein.

The term “non-steroidal anti-inflammatory drug” or “NSAID” means a molecule that inhibits the catalytic activity of one or both of cyclooxygenase-2 (COX-2) and cyclooxygenase-1 (COX-1). For example, a NSAID can selectively inhibit the catalytic activity of COX-2. In other examples, a NSAID can inhibit the catalytic activity of COX-1 and COX-2. Exemplary assays for measuring the catalytic activity of COX-1 and COX-2 are described herein. Additional assays for measuring the catalytic activity of COX-1 and COX-2 are known in the art. Additional exemplary properties of NSAID are described herein.

Substantial research has determined that at sites of inflammation, COX-2 is the primary cyclooxygenase responsible for the generation of the pro-inflammatory prostanoid, PGE2. Since PGE2 levels are major drivers of the cardinal signs of inflammation, then inhibition of COX-2 leads to reductions of these signs at sites of inflammation. For example, in an osteoarthritic knee joint, oral administration of a COX-2 inhibitor is effective at reducing pain, swelling, and loss of function. This oral administration comes with an increased risk of side effects due to the systemic exposures necessary to drive local concentrations that are sufficiently high to be pharmacologically active in the local environment of the knee joint.

Benzenesulfonamide-Containing NSAIDs

The compositions (e.g., gels, e.g., hydrogels) provided herein include a benzenesulfonamide-containing NSAID. In some examples, the benzenesulfonamide-containing NSAID inhibits the catalytic activity of COX-2. In other examples, the benzenesulfonamide-containing NSAID inhibits the catalytic activity of COX-1. In other examples, the benzenesulfonamide-containing NSAID inhibits the catalytic activity of both COX-1 and COX-2. For example, the benzenesulfonamide-containing NSAID can inhibit the catalytic activity of one or both of COX-1 (e.g., human COX-1) and COX-2 (e.g., human COX-2) with an IC50 of about 0.05 nM to about 50 μM, about 45 μM, about 40 μM, about 35 μM, about 30 μM, about 25 μM, about 20 μM, about 15 μM, about 10 μM, about 5 μM, about 1 μM, about 950 nM, about 900 nM, about 850 nM, 800 nM, about 750 nM, about 700 nM, about 650 nM, about 600 nM, about 550 nM, about 500 nM, about 450 nM, about 400 nM, about 350 nM, about 300 nM, about 250 nM, about 200 nM, about 150 nM, about 100 nM, about 95 nM, about 90 nM, about 85 nM, about 80 nM, about 75 nM, about 70 nM, about 65 nM, about 60 nM, about 55 nM, about 50 nM, about 45 nM, about 40 nM, about 35 nM, about 30 nM, about 25 nM, about 20 nM, about 15 nM, about 10 nM, about 5 nM, about 1 nM, about 0.5 nM, or about 0.1 nM;

In some examples, a gelling agent can be used to induce gelation of a composition. In some examples, a higher concentration of a gelling agent can dissolve a benzenesulfonamide-containing NSAID in a physiologically acceptable buffer (e.g., phosphate buffered saline). In some embodiments, e.g., a gelling agent can dissolve a benzenesulfonamide-containing NSAID and can be used to result in a solution (e.g., an aqueous solution) including the benzenesulfonamide-containing NSAID. In some embodiments, a gelling agent can result in the formation of a gel (e.g., a silk fibroin hydrogel) including a benzenesulfonamide-containing NSAID. In some embodiments, a gelling agent can act as a surfactant to aid in the stabilization of a particle or a plurality of particles that include one or more benzenesulfonamide-containing NSAID (e.g., any of the benzenesulfonamide-containing NSAIDs described herein) in a fluid (e.g., a pharmaceutically acceptable solvent or buffer, e.g., phosphate buffered saline). For example, Tween-80 is a gelling agent that can be used as a surfactant to stabilize a particle or a plurality of particles that include one or more benzenesulfonamide-containing NSAIDs.

Methods of Making Compositions—Part A

Also provided herein are methods of making a composition (e.g., a gel, e.g., a hydrogel) including: (a) providing a first solution including about 1% (w/v) to about 60% (w/v) silk fibroin (e.g., silk fibroin having a molecular weight of about 10 kDa to about 500 kDa (or any of the subranges described herein)); (b) providing a second solution including about 0.02% (w/v) to about 100% (w/v), or about 0.02% (v/v) to about 100% (v/v), of a gelling agent (e.g., any of exemplary gelling agents described herein) and about 1 mg/mL to about 100 mg/mL of a benzenesulfonamide-containing NSAID (e.g., any of the exemplary benzenesulfonamide-containing NSAIDs described herein or known in the art); (c) mixing a volume of the first solution with a volume of the second solution, where the ratio of the volume of the first solution to the volume of the second solution is about 5:1 to about 1:5 to provide a mixture; and (d) incubating the mixture for a time sufficient to form the composition (e.g., gel, e.g., hydrogel).

Any of the concentrations of silk fibroin described herein may be determined using the methods described in Example 3. The silk concentrations (% w/v) described in the Examples were all determined using the method described in Example 3.

Silk fibroin concentrations in a composition can also be determined using a gravimetric method. For example, in an exemplary gravimetric method, a 1 mL aliquot of silk fibroin solution (after dialysis) can be weighed into a tared container, the container incubated at 60° C. for 16-24 hours to evaporate any water, and the mass of silk fibroin remaining is used to determine the concentration of silk fibroin in a solution (mass silk fibroin/aliquot volume).

The concentration of a benzenesulfonamide-containing NSAID in any of the compositions (e.g., hydrogels or organogels) provided herein can be determined by placing 50 mg of the composition in 5 mL of methanol, and extracting the benzenesulfonamide-containing NSAID by shaking at room temperature for at least 24 hours. Following extraction, the supernatant is separated by either filtration or centrifugation and analyzed by high performance liquid chromatography to determine the concentration of the benzenesulfonamide-containing NSAID present in the composition (e.g., hydrogel or organogel).

The second solution can be an aqueous solution (e.g., a pharmaceutically acceptable aqueous solution, such as saline or phosphate buffered saline). The second solution can include a single gelling agent (e.g., any of the exemplary gelling agents described herein or known in the art). In other examples, the second solution can include two or more different gelling agents (e.g., any combination of the exemplary gelling agents described herein or known in the art). The second solution can have a concentration of the gelling agent (or a final total concentration of two or more gelling agents) of about 0.02% (w/v) to about 100% (w/v), about 98% (w/v), about 96% (w/v), about 94% (w/v), about 92% (w/v), about 90% (w/v), about 88% (w/v), about 86% (w/v), about 84% (w/v), about 82% (w/v), about 80% (w/v), about 78% (w/v), about 76% (w/v), about 74% (w/v), about 72% (w/v), about 70% (w/v), about 68% (w/v), about 66% (w/v), about 64% (w/v), about 62% (w/v), about 60% (w/v), about 58% (w/v), about 56% (w/v), about 54% (w/v), about 52% (w/v), about 50% (w/v), about 48% (w/v), about 46% (w/v), about 44% (w/v), about 42% (w/v), about 40% (w/v), about 38% (w/v), about 36% (w/v), about 34% (w/v), about 32% (w/v), about 30% (w/v), about 28% (w/v), about 26% (w/v), about 24% (w/v), about 22% (w/v), about 20% (w/v), about 18% (w/v), about 16% (w/v), about 14% (w/v), about 12% (w/v), about 10% (w/v), about 8% (w/v), about 6% (w/v), about 4% (w/v), about 2.5% (w/v), about 2% (w/v), about 1.5% (w/v), about 1.0% (w/v), about 0.5% (w/v), about 0.1% (w/v), about 0.5% (w/v), or about 0.1% (w/v) (inclusive);

The inflammatory and/or pain condition can be, e.g., selected from the group of: a joint pain and/or inflammatory diseases, musculoskeletal pain, back pain, neuropathic pain, nocioceptive pain, acute pain, chronic pain, inflammatory pain, operative pain, post-operative pain, visceral pain, incident pain, breakthrough pain, psychogenic pain, psoriasis, Crohn's disease, irritable bowel syndrome, Sjogren's disease, tissue graft rejection, asthma, systemic lupus erythematosus, glomerulonephritis, dermatomyositis, multiple sclerosis, scleroderma, vasculitis, Goodpasture's syndrome, atherosclerosis, chronic idiopathic thrombocytopenic purpura, Addison's disease, Parkinson's disease, Alzheimer's disease, diabetes, septic shock, myasthenia gravis, inflammatory pelvic disease, inflammatory bowel disease, urethritis, uveitis, sinusitis, pneumonitis, encephalitis, meningitis, myocarditis, nephritis, osteomyelitis, myositis, hepatitis, gastritis, enteritis, dermatitis, appendicitis, pancreatitis, cholocystitis, polycystic kidney disease, and a cancer. In some examples, the inflammatory condition is a joint disease. Non-limiting examples of a joint disease include osteoarthritis, rheumatoid arthritis, spondyloarthritis, systemic juvenile idiopathic arthritis, psoriatic arthritis, gout, ankylosing spondylitis, and juvenile rheumatoid arthritis.

Successful treatment of an inflammatory and/or pain condition can be determined (e.g., determined by a medical professional) by detecting one or more of: a reduction in the number of symptoms of the inflammatory and/or pain condition in the subject, a reduction of the severity of one or more symptoms of the inflammatory and/or pain condition in the subject, a reduction in the duration of one or more symptoms of the inflammatory and/or pain condition in the subject, and a reduction in the frequency of one or more symptoms of the inflammatory and/or pain condition in the subject. Symptoms of inflammatory and/or pain conditions are known in the art.

For example, successful treatment of an inflammatory condition can be determined by detecting a detectable reduction in the level/severity one or more (e.g., two or more) markers/symptoms of inflammation in a subject following administration of a therapeutic agent (e.g., any of the compositions (e.g., gels, e.g., hydrogels organogels) provided herein) as compared to the level/severity of the one or more (e.g., two or more) markers/symptoms of inflammation in the subject prior to administration of the therapeutic agent. Non-limiting examples of symptoms of inflammation include: pain, heat, redness, swelling, and loss of function. Non-limiting examples of markers of inflammation include prostaglandins (e.g., PGE2), erythrocyte sedimentation rate (ESR), white cell count, interleukin (IL)-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12, IL-13, tumor necrosis factor (TNF)-α, TNF-β, tumor growth factor-β, interferon-γ, GCSF, GM-CSF, C-reactive protein, serum amyloid P component, serum amyloid A, complement protein C3, complement protein C5a, factor XII, membrane attack complex (complement system), plasmin, thrombin, mannan-binding lectin, fibrinogen, prothrombin, factor VIII, von Willebrand factor, plasminogen activator inhibitor PAI-1, alpha 2-macroglobulin, ferritin, hecidin, ceruloplasmin, haptoglobin, orosomucoid, α-1-antitrpysin, α-1-antichymotrypsin, histamine, and leukotriene B4. For example, successful treatment of an inflammatory condition can result in a decrease in pain (e.g., inflammatory pain) in the subject. For example, treatment of an inflammatory condition can result in a decrease in the pain associated with the inflammatory condition.

For example, successful treatment of a pain condition can be determined by detecting a detectable decrease in a subject's pain intensity following administration of a therapeutic agent (e.g., any of the compositions (e.g., gels, e.g., hydrogels or organogels) provided herein) as compared to the intensity of the subject's pain prior to administration of the therapeutic agent.

The invention is further described in the following examples, which do not limit the scope of the invention described in the claims.

EXAMPLES

Example 1. Sustained Release of a Benzenesulfonamide-Containing NSAID from a Gel Including Silk Fibroin and a PEG

A set of experiments were performed to evaluate the drug release profile of different gels including silk fibroin, a PEG, and one of several different NSAIDs. The materials and methods used to perform these studies are described below.

Materials

Lyophilized silk fibroin (0.3 g per vial) was purchased from Simatech Inc. (Suzhou, China). Celecoxib was purchased from Matrix Scientific (Elgin, S.C.). The other NSAIDs, pharmaceutical grade (Kollisolv®) PEGs, and all other chemicals were purchased from Sigma-Aldrich (St. Louis, Mo.).

Methods

Drug Loading in Silk-PEG Hydrogel

Lyophilized silk was dissolved with ultrapure water to obtain concentrations of 1.3, 3.6, 7.0, 13.0, and 23.0% (w/v). Polyethylene glycol (PEG) with molecular weights of 300 and 400 Da (PEG300 and PEG400) was diluted with ultrapure water when necessary. Celecoxib (a benzenesulfonamide-containing NSAID) and other NSAIDs which are not benzenesulfonamide-containing NSAIDs (tenoxicam, meloxicam, and lomoxicam) were dissolved with 80% (v/v) PEG400 solution to obtain low concentration solutions (<40 mg/mL) or with 100% (v/v) PEG300 to obtain high concentration solutions (>100 mg/mL). Diclofenac sodium salt (another NSAID that is not a benzenesulfonamide-containing NSAID) was dissolved in the aqueous silk solution.

The PEG or PEG/drug solution was mixed with silk solution by pipetting up and down gently and aliquoted into a 2-mL Eppendorf tube. The detailed components of each tube is shown in Tables 1 to 7 below. Each tube was left at 37° C. to gel overnight (Wang et al., Acta Biomater. 12:51-61, 2015).

In Vitro Release Study

To the 2-mL Eppendorf tube containing fibroin-drug hydrogel, 1.95 mL of release medium was added. The release medium contained 1× phosphate buffer, pH 7.4, 0.1% (v/v) Tween-80, and 0.02% (w/v) sodium azide. The samples were incubated at 37° C. with gentle shaking. The release medium was changed after 24 hours and then approximately once every 3 days. The release medium was subjected to UV detection using a UV transparent bottom plate (Corning) at the respective wavelengths listed in Table 8. Control release medium was measured under the same condition for background subtraction. A calibration curve was generated for each drug by dissolving a known amount of each drug in the release medium, and making dilutions with the release medium.

TABLE 8
UV Detection Wavelength (nm) Used to Detect NSAIDs
Drug                   Wavelength (nm)
Celecoxib              260
Diclofenac Sodium Salt 280
Lomoxicam              380
Meloxicam              365
Tenoxicam              370

Results

The cumulative release of lomoxican from silk-fibroin hydrogels plateaued at day 6 for all the tested silk-fibroin hydrogel formulations, while the release of the drug with no fibroin plateaued at day 2 (FIG. 1). The diclofenac sodium salt was completely released from all the tested silk-fibroin hydrogels within 4 days (FIG. 2). Meloxicam was completely released from all the tested silk-fibroin hydrogels within 2 days (FIG. 3). Tenoxicam was completely released from all the tested silk-fibroin hydrogels within 5 days (FIG. 4).

Celecoxib was released within 30 days in silk-fibroin hydrogels containing celecoxib concentrations of 0.09375% (w/v) and 0.1875% (w/v), while celecoxib was released within 75 days in silk-fibroin hydrogels having a celecoxib concentration of 0.375% (w/v) (FIG. 5). All silk-fibroin hydrogels were prepared at 6.5% (w/v) fibroin. The data show that higher drug loading resulted in a slower and more linear release of celecoxib from the silk-fibroin hydrogel, as compared to lower celecoxib drug loadings (FIG. 5). The greater than 100% release observed for some samples is likely due to mass balance issues due to background subtraction from controls (e.g., silk alone) during UV absorbance determinations.

The data in FIG. 6 show that celecoxib release occurs over 41 days for hydrogels having fibroin concentrations of 12.5% (w/v) and 3.5% (w/v), while celecoxib release occurs over 30 days for hydrogels having a fibroin concentration of 1.3% (w/v), over 15 days for hydrogels having a fibroin concentration of 0.65% (w/v), and over 6 days for a no fibroin/“free” celecoxib sample (0% silk-fibroin hydrogels). The data in FIG. 7 show that all hydrogels released celecoxib for extended time period within 56 days, while hydrogels including low celecoxib concentration (1 mg) and low fiborin concentration (3.5% (w/v)) released celecoxib faster than the other samples.

In sum, these data show that the sustained release (e.g., greater than one week) of lomoxicam, meloxicam, tenoxicam, and diclofenac sodium salt could not be achieved using a silk-fibroin hydrogel delivery platform, i.e., these drugs were released within a one-week time period. Free lomoxican, meloxicam, tenoxicam, and diclofenac without encapsulation in silk-fibroin hydrogels were released within one day. In other words, the silk-fibroin hydrogel did slow the release of lomoxicam, meloxicam, tenoxicam, and diclofenac sodium salt to a limited extent.

Surprisingly, celecoxib interacted with the silk-fibroin in the gel in such a way that its release was sustained over two months when fibroin concentrations in the hydrogel were 3.5% (w/v) to 6.5% (w/v). The data show that the silk-fibroin hydrogels provide for the slow release of celecoxib at a therapeutically effective amount of ˜40 μg a day for more than 75 days.

Example 2. Treatment of Acute Knee Inflammation and Pain in a Rat Model Using a Celecoxib Silk-Fibroin Hydrogel Composition

A set of experiments was performed to determine if intraarticular injection of a celecoxib silk-fibroin hydrogel composition would successfully treat acute knee inflammation and pain in a rat model.

Materials and Methods

PGPS Induction

A PGPS (peptidoglycan-polysaccharide) rat model of acute knee inflammation and pain as described in Esser et al., Arth. Rheum. 28(12): 1402-1411, 1985 was used in these experiments. Rats were either left untreated or received a single intraarticular injection of 50 μL at day 0 of vehicle (“vehicle”), celecoxib alone (“Drug alone”), 6.5% (w/v) silk-fibroin hydrogel not including celecoxib (“Hydrogel 1”), 6.5% (w/v) silk-fibroin hydrogel including 100 mg/mL celecoxib (“Hydrogel 1 with drug), 3.5% (w/v) silk-fibroin hydrogel not including celecoxib (“Hydrogel 2”), or 3.5% (w/v) silk-fibroin hydrogel including 100 mg/mL celecoxib (“Hydrogel 2 with drug”) (FIG. 8) (Table 9). The specific hydrogels administered in these experiments are shown in Table 10. The control and silk-fibroin hydrogels were intraarticularly administered in the rat model.

Formulations were prepared by dissolving lyophilized silk fibroin with ultrapure water to obtain concentrations of either 7.0 or 13.0% (w/v). Celecoxib was dissolved in PEG300 to obtain 200 mg/mL concentration. Silk fibroin solution and celecoxib solution were drawn into separate 1 cc. syringes, connected via a luer connector and mixed back and forth 25 times or until homogeneous. Hydrogels were left to form at room temperature for at least 16 hours.

For priming, animals were anesthetized with isoflurance and given an intraarticular injection of peptidoglycan polysaccharride (PGPS) (50 μL of 0.125 mg/mL) into the right knee. The knee arthritis was reactivated with an intravenous (IV) injection of PGPS (0.5 mL of 0.4 mg/mL).

Gait Analysis

Gait analysis and hind limb pain (Von Frey) score for secondary allodynia, as well as knee inflammation (knee diameter), were measured over days 1-11 of the study. Gait analysis was performed by applying ink to the ventral surface of the foot and documenting weight bearing during movement (footprints) across paper. The rear feet of rats were placed in ink and then rats were placed on paper and allowed to walk the full length. This process was repeated as necessary to generate 4 clear, evenly inked footprint pairs representing the overall pattern of gait. Gait were scored visually as follows (descriptions refer to diseased leg):

• • 0=Normal, approximately equal ink staining to normal paw
  • 1=Slight limp/pain=reduced inking area relative to the normal paw, but no full regions or structures are missing
  • 2=Mild limp/pain=Print extends to the end or near to the end of the “curlicue” structure. If normal paw has very little heel staining (rat walks mainly on toes/ball of foot), then slightly less staining
  • 3=Moderate limp/pain=toes and full ball of foot, extending to the top of the “curlicue” foot. If normal paw has very little heel staining (rat walks mainly on toes/ball of foot), then toes with small portion of ball of foot.
  • 4=Marked limp/pain=toes and partial ball of foot, no heel or posterior foot. If normal paw has very little heel staining (rat walks mainly on toes/ball of foot), then toes only.
  • 5=Severe limp/pain=toes only, no ball of foot, no heel. If normal paw has very little heel staining (rat walks mainly on toes/ball of foot), then partial toes or non-specific marks
  • 6=Hopping or Carrying leg, no footprint is evident.

Knee Caliper Measurements

Caliper measurements of right and left knee diameters were done on assigned days using a Digitrix II micrometer caliper (Fowler & NSK). Baseline knee caliper measurements were taken using one knee with values rounded to one-thousandth of an inch. The measurements were confirmed as clinically normal by comparison with historical values for rats based on a range of body weights. Baseline measurements were then applied to both knees, and these values remained with the animal so long as the knee was clinically normal. Caliper measurements were done 48 and 96 hours post each reactivation.

Results

The data in FIGS. 9 and 10 show that intraarticular administration of the tested silk-fibroin celecoxib hydrogels to the knee of the rat model resulted in a decreased gait analysis score (which indicates a reduced amount of pain in the treated knee). The data in FIGS. 11 and 12 show that intraarticular administration of the tested silk-fibroin celecoxib gels to the knee of the rat model resulted in an increased Von Frey Filment (g) measurement, which indicates less pain in the knee. The data in FIGS. 13 and 14 show that intraarticular administration of the tested silk-fibroin celecoxib gels to the knee of the rat model results in a decrease in the diameter of the knee of the rat model, which indicates a decrease in the inflammation of the knee.

In sum, these data show that pain relief and a reduction in inflammation was achieved following intraarticular administration of a silk-fibroin celecoxib gel in rat model of acute knee inflammation and pain.

Example 3. Determining Silk-Fibroin Molecular Weight Range for Gelation Summary

Methods

Briefly, silk yarn from SOHO was degummed at 100° C. for either 15, 30, 45, 60, 90, 120, or 240 minutes in 0.02 M sodium carbonate solution to remove sericin and modify the molecular weight (MW) of the fibroin. The fibroin was then dried overnight, weighed, and dissolved at 20% (w/v) in a 9.3 M aqueous solution of lithium bromide for five hours at 60° C. The resulting fibroin solution was dialyzed against water in 3.5 kDa regenerated cellulose dialysis tubing for 48 hours with six water changes to remove the excess salt. The final solution was centrifuged three times for 20 minutes each at 9,000 RPM and 4° C. to remove insoluble particles. Solutions were diluted to a final concentration of 3% (w/v) in 10 mM phosphate buffer, pH 7.4. Half of these solutions were then autoclaved for 30 minutes. The solution that was degummed for 240 minutes and then autoclaved was then split and half was autoclaved for a second time. 10 mL of each solution was aliquoted into 50 mL conical tubes, frozen, and lyophilized for 72 hours.

To form the hydrogels, lyophilized silk-fibroin was reconstituted with 2 mL of deionized (DI) water. One half mL of this solution was then drawn into a 1 cc. syringe. One half mL of 100% PEG300 was drawn into a separate 1 cc. syringe. These syringes were then connected with a luer-lok connector and mixed back and forth roughly 50× or until homogeneous. The mixture was pushed into one syringe, capped with a 27 gauge needle, and left to cure at room temperature overnight.

The reconstitution efficiency of each of the degumming methods was then determined using the following assay. A sample of the reconstituted fibroin solution used to prepare the hydrogel was diluted 20× and 40× in 10 mM phosphate buffer, pH 7.4. Two hundred μL of this solution was read on a UV plate reader at 280 nm and compared to a standard curve of known silk concentrations. The reconstitution efficiency was calculated as the actual fibroin concentration read on the plate reader divided by the theoretical fibroin concentration multiplied by 100%. For example, if all of the fibroin dissolved with the addition of 2.0 mL DI water, the concentration measured via absorbance at 280 nm should read 13% (w/v) fibroin. This would be equivalent to a reconstitution efficiency of 100%. Complete and efficient fibroin reconstitution is required to reproducibly prepare fibroin-based hydrogels. The molecular weight of each solution was then determined using size exclusion chromatography (SEC)-UV. The silk-fibroin solutions were diluted to 3 mg/mL in 100 mM phosphate buffer at a pH of 6.8 to be analyzed on a SEC-HPLC-UV system. A Waters SEC 450 protein standard was used to generate a standard curve (based on protein MW and retention time) to determine silk-fibroin MW. The samples and standards (5 μL) were injected onto a WATERS XBridge Protein BEH SEC, 450 Å column. The mobile phase (100 mM phosphate buffer at a pH of 6.8) was pumped at 0.86 mL/min. The absorbance was recorded at 280 nm.

Results

Table 11 shows that silk that was degummed for at least 90 minutes or had been autoclaved at least once achieved reconstitution efficiencies of 85% or greater.

The size exclusion chromatography (SEC) results in FIG. 15 show that a wide range of molecular weights that can be achieved simply by degumming the silk at 100° C. in 0.02 M sodium carbonate solution for differing amounts of time (28-818 kDa). Also, the data show that the autoclave cycle leads to significant fibroin hydrolysis, drastically lowering the molecular weight. This data in combination with the reconstitution efficiency data suggests that silk-fibroin with a molecular weight on ≤˜100 kDa will have a reconstitution efficiency of ≥85% (FIG. 15).

TABLE 11
Reconstitution Efficiencies of the Silk-Fibroin Post-Lyophilization

01	15	No	14.1
02	30	No	33.5
03	45	No	54.6
04	60	No	83.1
05	90	No	85.9
06	120	No	90.6
07	240	No	92.1
08	15	Yes	89.9
09	30	Yes	85.0
10	45	Yes	94.7
11	60	Yes	95.8
12	90	Yes	93.0
13	120	Yes	98.1
14	240	Yes	98.5
15	240	Twice	101.0

These data show that the longer silk-fibroin is heated at 100° C., the lower the molecular weight of the degummed silk-fibroin. Autoclaving the fibroin solution after degumming also drastically lowered the molecular weight. Additionally, this study did not find any lower limit of silk-fibroin molecular weight that would not allow for hydrogel formation (final PEG300 concentration of 50% (v/v)). The data show that silk fibroin with a molecular weight as low as 16 kDa was able to form a hydrogel. The data show that the reconstitution efficiency of lyophilized silk-fibroin increases as the molecular weight of silk-fibroin decreases.

Example 4. Effect of Celecoxib Loading on Release Kinetics from Silk-Fibroin Hydrogels

Methods

Silk cocoons from Treenway were degummed at 100° C. for 60 minutes in 0.02 M sodium carbonate solution to remove sericin. The fibroin was then dried overnight, weighed, and dissolved at 20% (w/v) in a 9.3 M aqueous lithium bromide solution for five hours at 60° C. The resulting solution was dialyzed against water with six water changes in 3.5 kDa regenerated cellulose dialysis membrane for 48 hours. The dialyzed solution was centrifuged three times at 9,000 RPM for 20 minutes and 4° C. to remove insoluble particles. The solutions were diluted to a final concentration of 3% in 10 mM phosphate buffer, pH 7.4, and autoclaved at 121° C. for 30 minutes. The solution was then filtered through a 0.22-μm filter aliquoted into 50-mL conical tubes, frozen, and lyophilized for 72 hours.

Purified fibroin was reconstituted with 2 mL of DI water. 0.5 mL of this solution was then drawn into a 1 cc. syringe. Separately, celecoxib was dissolved in PEG300 at either 200 or 60 mg/mL, for the 100 mg/mL and 30 mg/mL gels, respectively. One-half mL of the celecoxib/PEG300 solution was drawn into a separate 1 cc. syringe. These syringes were connected with a luer-lok connector and mixed back and forth approximately 50× or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and left to gel at room temperature overnight.

In vitro release was carried out by weighing 50 mL-conical tubes and measuring approximately 50-100 mg of gel into the tubes and recording the actual weight for measurement. A suspension control was generated by mixing 25 μL of 200 mg/mL celecoxib in PEG-300 with 25 μL of DI water. Forty-five mL of release medium (1× phosphate buffered saline, 2% (v/v) Tween-80, and 0.05% sodium azide) was added to each tube. The samples were incubated at 37° C. under shaking. One mL of release media was collected at days 1, 3, 7, 10, 14, 21, 28, 36, and 42 and replaced with fresh media. The release media was analyzed by high performance liquid chromatography (HPLC) at 260 nm. The solubility of celecoxib in this release media is 850 μg/mL (data not shown). Forty-five mL of this release media allows 38 mg celecoxib to be dissolved. In this study, where samples contain either 5 mg or 1.5 mg celecoxib, this media will ensure sink conditions (≥5× celecoxib solubility) are maintained throughout the study. During the study, the tubes were placed on their sides and shook at 55 RPM and 37° C.

Results

FIG. 16 shows that celecoxib release kinetics from silk fibroin hydrogels are related to celecoxib loading. The 30 mg/mL celecoxib hydrogels released celecoxib over 7 days, while the 100 mg/mL celecoxib hydrogels released celecoxib over 28 days. These data also shows the effect of the silk hydrogel on release kinetics. The suspension control and 100 mg/mL celecoxib-loaded fibroin hydrogel contained the same concentration of celecoxib. The suspension control displayed complete release in 24 hrs as compared to 28 days sustained release exhibited by the 6.5% (w/v) fibroin hydrogel.

Fibroin hydrogel formulations release celecoxib slower than drug suspensions alone, and the same volume of higher celecoxib-loaded hydrogel will release for a longer period of time. These data show clear differences between release rates of celecoxib from hydrogels which is related to celecoxib loading. A pure suspension of celecoxib will completely dissolve in the release medium in one day, as expected when under sink conditions. A silk fibroin hydrogel with 30 mg/mL celecoxib will release completely by day 7, and a silk fibroin hydrogel with 100 mg/mL celecoxib will release in approximately one month (under these test conditions).

These release curves are expected not to match in vivo release in the joint space as the solubility of celecoxib is much lower in synovial fluid than in 1×PBS and 2% Tween-80. As the solubility of celecoxib is much lower in synovial fluid (as compared to the buffer used in these studies), the same hydrogels are thought to have slower (more-extended) release profile of celecoxib as compared to the release profile in these in vitro studies.

Example 5. Effect of Silk Fibroin Source on Release Kinetics of Celecoxib from Silk-Fibroin Hydrogels

Methods

Silk was purchased from three sources: Treenway Cocoon, Treenway facial grade Cocoons, and SOHO silk yarn. The facial grade cocoons are similar to the standard cocoon except the worm has already been removed and the inside has been cleared of the majority of debris and particulates generally seen as a result of the worm's presence.

Silk yarn or cocoons were degummed at 100° C. in 0.02 M sodium carbonate for 60 minutes followed by three room temperature water washes. The fibroin was dried, dissolved at a final concentration of 20% (w/v) with 9.3 M lithium bromide, and dialyzed in 3.5 kDa regenerated cellulose dialysis membrane against deionized (DI) water for two days. The resulting silk fibroin solution was then diluted to a final concentration of 3% (w/v) and 10 mM phosphate buffer, pH 7.4, and then autoclaved at 121° C. for 30 minutes. The resulting fibroin was then filtered through a 0.22-μm filter unit and aseptically frozen on dry ice, followed by lyophilization for 72 hours. The molecular weight of each silk-fibroin sample before and after autoclaving was determined by size exclusion chromatography (SEC). The silk-fibroin solutions were diluted to 3 mg/mL in 100 mM phosphate buffer at a pH of 6.8 to be analyzed on SEC-HPLC-UV system. A Waters SEC 450 protein standard was used to generate a standard curve (based on protein MW and retention time) to determine silk fibroin molecular weight. The samples and standards (5 μL) were injected onto a WATERS XBridge Protein BEH SEC, 450 Å column. The mobile phase (100 mM phosphate buffer at a pH of 6.8) was pumped at 0.86 mL/min. The absorbance was recorded at 280 nm.

Silk-fibroin hydrogels were prepared by reconstituting the lyophilized fibroin from each source (Treenway cocoon, Treenway facial grade cocoons, and SOHO yarn) to 13% (w/v) or 7% (w/v) final fibroin concentration. The celecoxib/PEG solution was prepared by dissolving 200 mg/mL celecoxib in PEG300. Five hundred μL of fibroin solution was drawn up in a 1 cc. syringe and 500 μL of celecoxib/PEG solution was drawn up in a second 1 cc. syringe. The syringes were connected with a luer-lock connector and the contents were mixed back and forth 25× or until the hydrogel was homogenous. The hydrogels were left to cure at room temperature overnight. The composition of the hydrogels in this study are described in Table 12.

The in vitro release was carried out by weighing 50 mg of formulation into separate tubes containing 45 mL of release medium (1× phosphate buffered saline, 2% (v/v) Tween-80, and 0.05% (w/v) sodium azide). The solubility of celecoxib in this release media is 850 μg/mL. Forty-five mL of this release media allows for 38 mg celecoxib solubility. In this study, where samples contain 5 mg celecoxib, this media will ensure sink conditions (≥5× celecoxib solubility) are maintained throughout the study. The tubes were incubated at 37° C. while shaking. One mL of the release media was collected from each sample at each time point after standing the tubes up and allowing for settling of any large particulates for 15 minutes. One mL of fresh release medium was then added back to each tube. The release media was analyzed by HPLC at 260 nm.

Results

The size exclusion chromatography data for the three silk fibroin sources is shown below in FIG. 17. The silk fibroin source had no effect on the molecular weight of silk-fibroin after either initial degumming or autoclave. Autoclaving the silk caused a decrease in molecular weight of silk-fibroin to approximately one third of the original molecular weight of the degummed solution (from ˜150 kDa to ˜55 kDa). FIG. 18 shows that the source of the silk did not affect the release of celecoxib at 100 mg/mL from 6.5% (w/v) silk-fibroin hydrogels. The trend was the same in the 3.5% (w/v) silk-fibroin hydrogels. FIG. 19 shows that when the concentration of silk fibroin in the hydrogel is between 3.5% (w/v) and 6.5% (w/v), it did not affect the release of celecoxib at 100 mg/mL celecoxib. The trend was the same for the three different silk fibrion sources (Treenway cocoons, Treenway facial cocoons, and SOHO silk yarn).

The source of the silk does not impact celecoxib release kinetics from silk-fibroin hydrogels. Varying the percentage of silk fibroin from 3.5% (w/v) to 6.5% (w/v) in silk hydrogels with 100 mg/mL celecoxib did not impact release kinetics.

Example 6. Effect of Fibroin Hydrogel Preparation Method on Release Kinetics of Celecoxib

Methods

Celecoxib Solution Hydrogel

Treenway silk cocoons were degummed at 100° C. for 60 minutes in 0.02 M sodium carbonate solution. The fibroin was dried overnight, weighed, and dissolved at 20% (w/v) in 9.3 M aqueous lithium bromide solution for five hours at 60° C. This solution was dialyzed against water with six water changes in 3.5 kDa regenerated cellulose dialysis membrane for 48 hours. The dialyzed solution was centrifuged three times at 9,000 RPM for 20 minutes and 4° C. to remove insoluble particles, diluted to a final concentration of 3% (w/v) in 10 mM phosphate buffer, pH 7.4, and autoclaved for 30 minutes. The solution was then filtered through a 0.22-μm filter, frozen, and lyophilized for 72 hours.

Purified fibroin (300 mg) was reconstituted with 2 mL of DI water. 0.5 mL of this solution was then drawn into a 1 cc. syringe. Separately, celecoxib was dissolved in PEG300 at 200 mg/mL. One-half mL of the celecoxib/PEG300 solution was drawn into a separate 1 cc. syringe. These syringes were connected with a luer-lok connector and mixed back and forth approximately 50× or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and left to gel at room temperature overnight.

Celecoxib Suspension Hydrogel

SOHO silk yarn was degummed at 100° C. for 120 minutes in 0.02 M sodium carbonate solution. The fibroin was dried overnight, weighed, and dissolved at 10% (w/v) in 9.3 M aqueous lithium bromide solution for five hours at 60° C. This solution was dialyzed against water with six water changes in 50 kDa cellulose ester dialysis membrane for 48 hours. The dialyzed solution was centrifuged at 9,000 RPM for 20 minutes and 4° C. to remove insoluble particles, diluted to a final concentration of 3% (w/v) in 10 mM phosphate buffer, pH 7.4. The solution was then filtered through a 0.22-μm filter, frozen, and lyophilized for 72 hours.

Purified fibroin (300 mg) was reconstituted with 1.55 mL of 30% (w/v) suspension of celecoxib in 0.4% (v/v) Tween 80. One mL of this solution was then drawn into a 6 cc. syringe. One-fourth mL water was then added to the syringe to dilute the fibroin/celecoxib suspension. Separately, 1.25 mL of PEG300 was drawn into a separate 6 cc. syringe. These syringes were connected with a luer-lok connector and mixed back and forth approximately 50× or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and left to gel at 37° C. overnight.

The in vitro release was carried out by weighing 50 mg of formulation into separate tubes containing 45 mL of release medium (1× phosphate buffered saline, 2% (v/v) Tween-80, and 0.05% (w/v) sodium azide). The solubility of celecoxib in this release media is 850 μg/mL. Forty-five mL of this release media can dissolved 38 mg of celecoxib. In this study, where samples contain 5 mg celecoxib, this media will ensure sink conditions (≥5× celecoxib solubility) are maintained throughout the study. The tubes were incubated at 37° C. while shaking. One mL of the release media was collected from each sample at each time point after standing the tubes up and allowing for settling of any large particulates for 15 minutes. One mL of fresh release medium was then added back to each tube. The release media was analyzed by HPLC at 260 nm.

The controls were prepared at Day 0 by placing 50 mg of each formulation in 100% methanol to extract celecoxib. The samples were left shaking at RT for at least 24 hrs. The supernatant was analyzed by HPLC to determine celecoxib loading (mg/g). The data in FIG. 20 show that the release kinetics from silk fibroin hydrogels prepared with a solution of celecoxib had a slightly higher burst compared to silk fibroin hydrogels prepared with a suspension of celecoxib (35% vs. 24% (w/v)). Also, the release kinetics of the hydrogel made using a celecoxib solution are faster over the first 7 days when compared to hydrogel made using a celecoxib suspension. Both formulations display a first-order release profile with complete release at 28 days (FIG. 20). A decrease in the burst of celecoxib can be beneficial in a mammal in order to reduce systemic exposure of the mammal to high concentrations of celecoxib.

Example 7. Effect of Fibroin Concentration on Release of Celecoxib from Silk-Fibroin Hydrogels Summary

Methods

Briefly, silk yarn from SOHO was degummed at 100° C. for 90 minutes in 0.02 M sodium carbonate solution to remove sericin. The resulting fibroin was then dried overnight, weighed, and dissolved at 10% (w/v) in 9.3 M lithium bromide solution for five hours at 60° C. The resulting solution was dialyzed against water in 50 kDa regenerated cellulose dialysis membrane for 48 hours at 4° C. with six water changes. The final solution was centrifuged for 20 minutes at 9,000 RPM and 4° C. to remove insoluble particles. The solutions were then diluted to a final concentration of 3% (w/v) in 10 mM phosphate buffer, pH 7.4, and filtered through a 0.22-μm filter, frozen in a dry ice-isopropanol bath, and lyophilized for 72 hours.

To form the hydrogels, lyophilized fibroin was reconstituted with a 30% (w/v) celecoxib (CXB) suspension in 0.4% (v/v) polysorbate 80. Table 14 lists the groups of hydrogels formed for this in vitro study. For Group 1, enough 30% (w/v) celecoxib suspension was added to bring the fibroin to 15% (w/v). A portion of this solution was serially diluted with 30% (w/v) celecoxib suspension to prepare the fibroin solutions for Groups 2-5. For each group, the fibroin/celecoxib suspension was diluted 5:1 with water (i.e., 1 mL fibroin/drug solution with 0.2 mL water). The PEG solution for all groups was prepared by diluting PEG300 to 96.15% (v/v) with 0.95 M hydrochloric acid. Fibroin/celecoxib and PEG300/HCl solutions were then combined at a ratio of 1.2:1.3 and mixed until homogeneous. The formulations were incubated at 37° C. on an orbital mixer for 16 hours to induce gelation.

The in vitro release was carried out by weighing 50 mg of formulation into half of a #4 gelatin capsule. The capsules were added to separate tubes containing 45 mL of release medium (1× phosphate buffered saline, 2% (v/v) Tween-80, and 0.05% (w/v) sodium azide). The solubility of celecoxib in this release media is 850 μg/mL. Forty-five mL of this release media can dissolve 38 mg celecoxib. In this study, where the samples contain either 5 mg or 1.5 mg celecoxib, this media will ensure sink conditions (≥5× celecoxib solubility) are maintained throughout the study. The tubes were incubated at 37° C. while shaking. One mL of the release media was collected from each sample at days 1, 4, 7, 10, and 14 after standing the tubes up and allowing for settling of any large particulates for 15 minutes. One mL of fresh release medium was then added back to each tube. The release media was analyzed by HPLC at 260 nm.

The controls were prepared at Day 0 by placing 50 mg of each formulation in 100% methanol to extract celecoxib. The samples were left shaking at RT for at least 24 hrs. The supernatant was analyzed by HPLC to determine celecoxib loading (mg/g).

FIG. 21 shows the 0.375% (w/v) hydrogels released 100% of the loaded celecoxib in one day. The 0.75% (w/v) hydrogels had a burst release of 70% of the loaded celecoxib and complete release by day 14. The groups containing 1.5, 3, and 6% (w/v) fibroin had the lowest burst of ˜40% of the loaded celecoxib with first-order release kinetics that showed complete release by day 28.

These data show clear differences between release rates of hydrogels having different silk fibroin concentrations. The general trend is that hydrogels with lower amounts of silk fibroin have greater celecoxib burst and a shorter duration of release. As the fibroin concentration of the hydrogels was increased, the hydrogels became more viscous, the burst was more reduced, and the release of celecoxib more sustained. The celecoxib release rates for hydrogels including between 1.5% (w/v) and 6% (w/v) silk fibroin are similar.

Glycerol, propylene glycol, and acetonitrile were purchased from Fisher Chemical (Waltham, Mass.). Celecoxib was purchased from Cipla (Mumbai, India). Sorbitol was purchased from Spectrum (New Brunswick, N.J.). PEG 4 kDa, PEG 6 kDa, and PEG 8 kDa were purchased from Clariant (Charlotte, N.C.).

Super-refined PEG300 for P00066 was supplied by Croda (Snaith, UK).

Silk-fibroin was purified in two batches. For batch 004-02, briefly, silk cocoons from Treenway were cut into dime sized pieces and boiled for 60 minutes in 0.02 M sodium carbonate solution to remove sericin. The fibroin was then dried overnight, weighed, and dissolved at 20% (w/v) in 9.3 M lithium bromide solution for five hours at 60° C. The resulting solution was dialyzed against water in 3.5 kDa regenerated cellulose dialysis tubing for 48 hours to remove the excess salt with six water changes. The final solution was then centrifuged three times for 20 minutes each at 9,000 RPM and 4° C. to remove insoluble particles. The solutions were then diluted to a final concentration of 3% (w/v) and 10 mM phosphate, pH 7.4. These solutions were autoclaved for 30 minutes, aliquoted into 50-mL conical tubes, frozen in a dry ice-isopropanol bath, and lyophilized.

Batch 26-01 was prepared in a similar manner. Silk yarn from SOHO was cut and boiled for 120 minutes in 0.02 M sodium carbonate solution to remove sericin. The fibroin was then dried overnight, weighed, and dissolved at 10% (w/v) in 9.3 M lithium bromide solution for five hours at 60° C. The resulting solution was dialyzed against water in 50 kDa cellulose ester dialysis tubing with 6 water exchanges for 48 hours at 4° C. to remove the excess salt. The final solution was then centrifuged once for 20 minutes at 9,000 RPM and 4° C. to remove insoluble particles. The resulting fibroin solution was then diluted to a final concentration of 3% (w/v) and 10 mM phosphate, pH 7.4. This solution was filtered through a 0.22-μm filter unit, aliquoted into 50-mL conical tubes, frozen in a dry ice-isopropanol bath, and lyophilized.

For the hydrogels listed in Tables 15, 17, and 19, PEG300, 400, and 600 solutions were prepared by diluting the gelling agent, if necessary, to twice the final formulation concentration listed with water. The silk-fibroin solution was formed by adding DI water to the lyophilized cake to bring it to a final concentration of 13% (w/v) (2.0 mL for 300 mg fibroin). Equal volumes of both the fibroin and corresponding gelling agent solution were drawn into two syringes, which were then connected by a luer-lok syringe connector and mixed back and forth approximately 25 times, or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and then either incubated at room temperature or 37° C. overnight. The formulations that did not result in a hydrogel were then extruded into a 2 mL glass HPLC vial and autoclaved at 121° C. for 30 minutes.

The hydrogels containing celecoxib listed in Tables 16, 18, and 20 were prepared by reconstituting purified silk-fibroin (300 mg) with 2.0 mL of 20% (w/v) suspension of celecoxib in 0.2% (v/v) Tween-80. The final celecoxib concentration in this reconstituted silk suspension was 174 mg/mL and the final silk concentration was 13% (w/v). The gelling agent solutions were prepared by diluting the gelling agent with water, if necessary, until it was twice the final formulation concentration listed. Equal volumes of both the fibroin and corresponding gelling agent solution were drawn into two syringes, which were then connected by a luer-lok syringe connector and mixed back approximately 25 times, or until homogeneous. For the first entry in Table 16 (50% (v/v) PEG300 with celecoxib), the PEG300 solution contained the dissolved drug at 200 mg/mL, which was then mixed with pure fibroin solution at 13% (w/v), resulting in final formulation concentrations of 6.5% (w/v) fibroin, 50% (v/v) PEG300, and 100 mg/mL celecoxib. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and then either incubated at room temperature or 37° C. overnight. The formulations that did not result in a hydrogel were then extruded into a 2 mL glass HPLC vial and autoclaved at 121° C. for 30 minutes.

The hydrogels listed in Tables 21, 23, 24, and 25, the PEG 2 kDa, 4 kDa, 6 kDa, and 8 kDa solutions were prepared by dissolving the dry PEG in water to twice the final formulation concentration listed. If necessary, the solutions were briefly heated at 60° C. to facilitate dissolution. The lyophilized silk fibroin was reconstituted with DI water to a final concentration of 13% (w/v) (2.0 mL for 300 mg silk fibroin). Equal volumes of both the 13% (w/v) silk fibroin solution and corresponding gelling agent solution were mixed. For Table 26, PEG 10 kDa would not dissolve at any concentration higher than 60% (w/v), so the protocol was slightly adjusted. Dry 10 kDa PEG was dissolved to a final concentration of 60% (w/v) with heating to 60° C. The lyophilized fibroin was reconstituted with DI water to a final concentration of 19.5% (w/v) (1.24 mL for 300 mg fibroin). These solutions were mixed at a ratio of 2:1 60% (w/v) PEG 10 kDa:19.5% (w/v) fibroin solution. The solutions were drawn into two syringes, connected by a luer-lok syringe connector and mixed back and forth approximately 25 times, or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and then either incubated at room temperature or 37° C. overnight. The formulations that did not result in a hydrogel were then extruded into a 2-mL glass HPLC vial and autoclaved at 121° C. for 30 minutes.

For the hydrogels containing celecoxib listed in Tables 22 and 27, purified fibroin (300 mg) was reconstituted with 2.0 mL of a 20% (w/v) suspension of celecoxib in 0.2% Tween 80, to bring the final celecoxib concentration to 174 mg/mL and the final silk concentration to 13% (w/v). The gelling agent solutions were prepared by dissolving the dry PEG in water until it was twice the final formulation concentration listed. Equal volumes of both the fibroin and corresponding gelling agent solution were drawn into two syringes, which were then connected by a luer-lok syringe connector and mixed back and forth approximately 25 times, or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and then incubated at 37° C.

For the hydrogels listed in Tables 28, 30, 31, and 32, the gelling agent solutions were prepared by diluting glycerol, glycerol formal, triethanolamine, or propylene glycol with water, if necessary, until they were twice the formulation concentrations listed. The fibroin solutions were prepared reconstituting lyophilized fibroin with DI water to a final concentration of 13% (w/v) (2.0 mL for 300 mg fibroin). Equal volumes of both the 13% (w/v) fibroin solution and corresponding gelling agent solution were mixed. For Table 34, the stock sorbitol was at 70% (w/v), so the first two entries had to have adjusted fibroin concentrations to reach 50 and 40% (w/v) final sorbitol concentration. The fibroin solutions were prepared reconstituting lyophilized fibroin with DI water to a final concentrations of either 22.7% (w/v) (1.02 mL for 300 mg fibroin) or 15.2% (w/v) (1.67 mL to 300 mg). The 50% (w/v) final sorbitol hydrogel was mixed at a ratio of 2.5:1 70% (w/v) sorbitol: 22.7% (w/v) fibroin solution, and the 40% (w/v) final hydrogel was mixed at a ratio of 1.33:1 70% (w/v) sorbitol to 15.2% (w/v) fibroin solution. For all hydrogels, gelling agent and fibroin solutions were drawn into separate syringes, which were then connected by a luer-lok syringe connector and mixed back approximately 25 times, or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and then either incubated at room temperature or 37° C. overnight. The formulations that did not result in a hydrogel were then extruded into a 2-mL glass HPLC vial and autoclaved at 121° C. for 30 minutes.

For the hydrogels containing celecoxib listed in Tables 29 and 33, purified fibroin (300 mg) was reconstituted with 2.0 mL of 20% (w/v) suspension of celecoxib in 0.2% (v/v) Tween 80, to bring the final celecoxib concentration to 174 mg/mL and the final silk concentration to 13% (w/v). Gelling agent solutions were prepared by diluting stock solution in water until twice the desired final concentration was reached. Equal volumes of both the fibroin and corresponding gelling agent solution were drawn into two syringes, which were then connected by a luer-lok syringe connector and mixed back approximately 25 times, or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and then incubated at 37° C. Formulations that did not result in a hydrogel were then extruded into a 2-mL glass HPLC vial and autoclaved at 121° C. for 30 minutes.

For the hydrogels listed in Table 35, the fibroin solution was prepared by dissolving 300 mg of lyophilized fibroin with polysorbate-80 solution in water to the final concentrations listed above. For example, 6.5% (w/v) fibroin and 0.2% (v/v) polysorbate-80 was prepared by adding 4.3 mL of 0.21% (v/v) polysorbate-80 in water to 300 mg of lyophilized fibroin. One mL of these solutions was aliquoted into separate 2-mL glass HPLC vials and autoclaved at 121° C. for 30 minutes.

For the hydrogel sample in Table 36, celecoxib was added to the polysorbate-80 solution used to reconstitute the silk so that the final concentration of the resulting solution was 87 mg/mL celecoxib. One mL of this solution was then left in a 2 mL-HPLC vial at 37° C. overnight.

Several different techniques were used to generate the hydrogels in Table 37. The first entry (1% (v/v) benzyl alcohol and no polysorbate-80), equal volumes of 13% (w/v) fibroin solution and 2% (v/v) benzyl alcohol solution were mixed via syringe connector until homogenous and left at room temperature overnight. The second entry (1% (v/v) benzyl alcohol and 0.2% (v/v) polysorbate-80) was formed by reconstituting the silk fibroin in polysorbate-80 to bring the final concentrations to 13% (w/v) fibroin and 0.4% (v/v) polysorbate-80, before equal volumes of this solution and 2% (v/v) benzyl alcohol were mixed via syringe connector until homogeneous and left at room temperature. The final two hydrogels in Table 23 were formed like this, with equal volumes of 13% (w/v) fibroin with either 0.8% or 0.4% (v/v) polysorbate-80 and 1.8% (v/v) solution of benzyl alcohol mixed via syringe connector until homogeneous. One mL of these solutions was then placed into a 2-mL glass HPLC vial and autoclaved at 121° C. for 30 minutes.

For the hydrogels listed in Tables 38 and 40, the two dry poloxamer powders were dissolved in water to twice the final formulation concentration listed. If necessary, the solutions were briefly cooled on ice and vortexed to facilitate dissolution. The fibroin solution was formed by adding DI water to the lyophilized cake to bring silk fibroin to a final concentration of 26%, 13%, or 7% (w/v) (1.0, 2.0, or 4.0 mL water, respectively). Equal volumes of both the silk fibroin solution and corresponding gelling agent solution were mixed. The solutions were drawn into two syringes, which were then connected by a luer-lok syringe connector and mixed back and forth approximately 25 times, or until homogeneous. The resulting mixture was then drawn into one syringe, capped with a 27 gauge needle, and then either incubated at room temperature or 37° C. overnight. The formulations that did not result in a hydrogel were then extruded into a 2-mL glass HPLC vial and autoclaved at 121° C. for 30 minutes.

For the hydrogels containing celecoxib listed in Tables 25 and 27, purified fibroin (300 mg) was reconstituted with 2.0 mL of a 20% (w/v) suspension of celecoxib in 0.2% (v/v) Tween 80, to bring the final celecoxib concentration to 174 mg/mL and the final silk concentration to 13% (w/v). The gelling agent solutions were prepared by dissolving the dry poloxamer in water to twice the final formulation concentration listed. Equal volumes of both the fibroin and corresponding gelling agent solution were drawn into two syringes, which were then connected by a luer-lok syringe connector and mixed back and forth approximately 25 times, or until homogeneous.

For the hydrogels listed in Tables 42 through 46, dry gelling agents were solubilized to 2× the final desired formulation concentration in water. Fibroin was reconstituted to a final concentration of 13% (w/v) (2.0 mL water to 300 mg fibroin). Equal volumes of both the fibroin solution and corresponding gelling agent solution were mixed. The solutions they were drawn into two syringes, which were then connected by a luer-lok syringe connector and mixed back and forth approximately 25 times, or until homogeneous.

To perform the in vitro release comparing hydrogels with different gelling agents, the samples were prepared as follows. A 30% (w/v) celecoxib suspension in 0.4% (v/v) polysorbate-80 was formed. This suspension was used to reconstitute fibroin to 16.2% and 251 mg/mL celecoxib. This fibroin/celecoxib solution was used to prepare all formulations below. The formulations were prepared as follows:

• • 50% (v/v) PEG300: The gelling agent solution (96.2% (v/v) PEG300, 3.65% (v/v) hydrochloric acid, and 0.15% (v/v) water) was prepared. Water was mixed with the fibroin/celecoxib solution in a ratio of 1:5 (i.e., 0.2 mL water to 1 mL fibroin/celecoxib). These gelling agent and fibroin/celecoxib solutions were mixed via syringe connector in a ratio of 1.3:1.2 until homogeneous. Syringes were filled with the mixture, capped with a 27 gauge needle, and left at 37° C. overnight.
  • 40% (v/v) PEG300: The gelling agent solution (66.6% (v/v) PEG300, 2.5% (v/v) hydrochloric acid, and 30.9% (v/v) water) was prepared. This solution and the fibroin/celecoxib solution were then mixed via syringe connector in a ratio of 1.5:1 until homogenous. Syringes were filled with the mixture, capped with a 27 gauge needle, and left at 37° C. overnight.
  • 40% (w/v) PEG 8 kDa: An HCl/salt solution was made by dissolving sodium chloride at 27 mg/mL in 0.068 N hydrochloric acid. A 66.6% (w/v) PEG 8 kDa solution was formed by dissolving dry PEG powder with the HCl/salt solution. This solution and the fibroin/celecoxib solution were then mixed via syringe connector in a ratio of 1.5:1 until homogenous. Syringes were filled with the mixture, capped with a 27 gauge needle, and left at 37° C. overnight.
  • 30% (w/v) Sorbitol: A solution of 50% (w/v) sorbitol was made by diluting 70% (w/w) sorbitol USP with DI water. This solution and the fibroin/celecoxib solution were then mixed via syringe connector in a ratio of 1.5:1 until homogenous. Syringes were filled with the mixture, capped with a 27 gauge needle, and left at 37° C. overnight.
  • 40% (v/v) Glycerol: Gylcerol was diluted to 66.6% (v/v) glycerol with DI water. This solution and the fibroin/celecoxib solution were then mixed via syringe connector in a ratio of 1.5:1 until homogenous. Syringes were filled with the mixture, capped with a 27 gauge needle, and left at 37° C. overnight.

The in vitro release was carried out by weighing 50 mg of formulation into half of a #4 gelatin capsule. The capsules were added to separate tubes containing 45 mL of release medium (1× phosphate buffered saline, 2% (v/v) Tween-80, and 0.05% (w/v) sodium azide). The solubility of celecoxib in this release media is 850 μg/mL. Forty-five mL of this release media dissolves 38 mg celecoxib. In this study then, where samples contain 5 mg celecoxib, this media will ensure sink conditions (≥5× celecoxib solubility) are maintained throughout the study. The tubes were incubated at 37° C. while shaking. One mL of the release media was collected from each sample at days 1, 4, 7, 14, 21, 28, 35, and 42 after standing the tubes up and allowing for settling of any large particulates for 15 minutes. One mL of fresh release medium was then added back to each tube. The Release media was analyzed by HPLC at 260 nm.

Peaks on the HPLC UV-Vis were integrated against a standard curve of known celecoxib amounts. This was used to generate concentrations of celecoxib in the release medium and total percent celecoxib release was then able to be calculated. The samples were formulated in triplicate which allowed for statistical analysis including standard deviation of release profiles.

Results

Hydrogel formation of a variety of formulations was studied at different curing conditions. Twenty-two different gelling agents were investigated. The final silk fibroin percentage of each formulation ranged from 3.5% (w/v) to 13% (w/v). The concentration of gelling agents ranged from 0.01 to 50%. The gelling agents studied were: PEG300, PEG400, PEG600, PEG 2 kDa, PEG 4 kDa, PEG 6 kDa, PEG 8 kDa, PEG 10 kDa, glycerol, glycerol formal, triethanolamine (TEA), propylene glycol, sorbitol, polysorbate-80 (Tween-80), benzyl alcohol (BA), poloxamer-188, poloxamer-407, hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), hydroxypropyl-β-cyclodextrin (HPBCD), polyvinylpyrrolidone-12 (PVP-12), and polyvinylpyrrolidone-17 (PVP-17).

Tables 48-80 detail the fibroin, gelling agent, and celecoxib concentrations in each hydrogel, as well as the curing temperatures. Twenty-five degree and 37° C. samples were removed after 24 hours and checked for hydrogel formation. Autoclaved samples (30 minute cycle at 121° C.) were processed in glass vials. The sample was then removed, and checked for hydrogel formation.

In general, higher concentrations of either silk fibroin or gelling agent and higher curing temperatures were more likely to lead to full gelation. It also appears that the addition of celecoxib increased the propensity of formulations to gel. This effect can be seen in Tables 15 and 16, where the 20% and 10% PEG300 gels with drug gelled after autoclaving, whereas they did not without drug.

Tables 48-53 detail the gelation results using a lower molecular weight PEG as a gelling agent. These include PEG300, 400 and 600. All three of these PEGs resulted in hydrogels when formulated with PEG concentrations greater than or equal to 40% (v/v). The addition of celecoxib reduced the PEG concentration required to induce gelation to as low as 30% (v/v) at either 37° C. or RT. Autoclaving celecoxib loaded formulations reduced this even further. PEG300 and PEG400 hydrogels formed at both 20% (v/v) and 10% (v/v) PEG with celecoxib and autoclaving.

Tables 54-60 detail the gelation results using a higher molecular weight PEG as a gelling agent. These include PEG 2 kDa, 4 kDa, 6 kDa, 8 kDa, and 10 kDa. In the absence of celecoxib, 2 kDa PEG formed a hydrogel at a concentration of 50% (w/v) at RT. The addition of 0.2% (v/v) Tween 80 as well as increasing the gelation temperature to 37° C., reduced the required PEG 2 kDa concentration to 30% (w/v). Autoclaving and 0.2% (v/v) Tween 80 allowed for hydrogel formation at 2 kDa PEG concentrations as low as 10% (w/v). Celecoxib (87 mg/mL) hydrogels were formed with 2 kDa PEG when the 2 kDa PEG concentration was 30% (w/v) and curing temperature was 37° C. Four kDa, 6 kDa, and 8 kDa PEG all performed similarly in that they formed hydrogels when used at a concentration of 40% (w/v) with a curing temperature of 37° C. In the absence of celecoxib, 10 kDa PEG formed a hydrogel when used at a concentration of 50% (w/v) at RT. The further addition of 0.2% Tween 80 increased the gelation temperature to 37° C., reduced the required 10 kDa PEG concentration to 30% (w/v). Autoclaving and the addition of 0.2% Tween 80 allowed for hydrogel formation using 10 kDa PEG concentrations as low as 10% (w/v). Celecoxib (87 mg/mL) hydrogels were formed with 10 kDa PEG when the 10 kDa PEG concentration was 30% (w/v) and the curing temperature was 37° C.

Tables 61-67 detail the gelation results using a variety of alternative, non-PEG based gelling agents, including glycerol, glycerol formal, triethanolamine (TEA), propylene glycol, and sorbitol.

In the absence of celecoxib, glycerol induced fibroin gelation at decreasing concentrations as curing temperature was increased. Minimum concentrations of 50%, 40% and 30% (v/v) glycerol formed hydrogels when cured at RT, 37° C., and after autoclaving, respectively. Similar to the absence of celecoxib, formulations containing 87 mg/mL celecoxib and a curing temperature of 37° C. formed hydrogels with at a minimum glycerol concentration of 40% (v/v). Glycerol formal elicited gelation at a minimum concentration of 40% (v/v) in the absence of celecoxib and RT curing. Autoclaving reduced the required gelation glycerol formal concentration to 20% (v/v).

Triethanolamine elicited gelation at a minimum concentration of 40% (v/v) in the absence of celecoxib and RT curing. Autoclaving reduced the required gelation triethanolamine concentration to 30% (v/v). Propylene glycol, similar to glycerol formal, elicited gelation at a minimum concentration of 40% (v/v) in the absence of celecoxib and RT curing. Autoclaving reduced the required gelation propylene glycol concentration to 20% (v/v). The addition of 87 mg/mL celecoxib, reduced the RT minimum gelation propylene glycol concentration to 30% (v/v) and autoclave minimum gelation propylene glycol concentration to 10% (v/v). Sorbitol, in the absence of celecoxib, only formed hydrogels at a concentration of 30% (w/v) at both RT and 37° C.

Tables 72-75 detail the gelation results using Poloxamer 188 and Poloxamer 407. These triblock polymers differ in properties based on their molecular weight and proportion of hydrophobic polypropylene oxide (PPO) and hydrophilic polyethylene oxide (PEO) blocks. In the absence of celecoxib and at a 6.5% (w/v) fibroin concentration, hydrogels could not be formed with either Poloxamer 188 or 407 at RT using Poloxamer 188 or 407 concentrations as high as 10% (w/v). Increasing the curing temperature to 37° C. allowed formulations with fibroin concentrations ranging from 13%-3.5% (w/v) to form hydrogels with Poloxamer 188 concentrations of 10% (w/v). Poloxamer 407 induced gelation at a concentration of 10% (w/v) when the formulations contained fibroin concentrations of 6.5% and 3.5% (w/v). Autoclaving reduced the required gelation Poloxamer 188 or Poloxamer 407 concentration to 0.25% (w/v) and 1% (w/v), respectively. Poloxamer 188 at a concentration of 10% (w/v) and a curing temperature of 37° C. allowed for the formation of a hydrogel with a final celecoxib concentration of 87 mg/mL celecoxib.

Tables 76-80 detail the gelation results using HEC, CMC, HPBCD, PVP-12, and PVP-17 as gelling agents.

The results are shown in FIG. 22. All formulations contained a final 6.5% (w/v) fibroin and 100 mg/mL celecoxib. Under these accelerated, sink conditions of in vitro release, all formulations displayed similar release kinetics with the exception of sorbitol which trended toward a slightly higher initial burst (30% vs. 25%) and shorter duration (28 days vs. 42 days).

Example 9. Degumming Method Effects on Human Whole Blood Activation Studies

Acute inflammatory responses are initiated via activation of a mammal's innate immune system. Human whole blood contains the principle repertoire of immune cells responsible for initiating an innate driven inflammatory response. Activation of inflammation in human whole blood is a useful in vitro assay for assessing the inflammatory potential of silk-fibroin hydrogel constituents. For this reason, whole human blood was exposed to silk fibroin solutions, three dimensional silk fibroin hydrogels, and a variety of different gelling agents for 24 hours at 37° C. and assessed for activation of inflammation.

Lipopolysaccharide (LPS) was used as a positive stimulator of the inflammatory marker TNF-α, in whole blood. Experiments to assess the inflammatory potential of formulation constituents were conducted both in the absence and the presence of lipopolysaccharide (LPS). The later condition to assess whether any formulation constituent had the activity of potentiating a known inflammatory signal. In each experiment, plasma was collected at the end of the incubation period and analyzed for TNF-α via enzyme-linked immunosorbent assay (ELISA).

In the absence of co-added LPS, soluble silk fibroin samples isolated using several different degumming techniques did not exhibit inflammatory signals beyond low baseline responses. In the presence of LPS, the TNF-α responses to silk fibroin prepared via variety of degumming methods were generally reduced compared to the response to LPS alone. Gelling agents PEG300, PEG400, 8 kDa PEG, glycerol, and sorbitol at relevant concentrations were similarly non-inflammatory +/−LPS, with some specific cases in which the gelling agent reduced the levels of LPS-induced TNF-α.

Finally, experiments were conducted to assess the affect of the three dimensional hydrogel structure on activation of the innate immune system. These experiments demonstrated that the three dimensional hydrogel structure had no effect on the LPS-induced TNF-α response irrespective of the original degumming method used to prepare the silk-fibroin hydrogels.

Additional experiments to assess cell viability in the whole blood experiments demonstrated that the conclusions based on TNF-α response would be unlikely to have been influenced by differential effects on cell viability. In sum, these data support the hypothesis that silk fibroin hydrogels and their constituents will have a low potential for inducing an acute inflammatory response in humans beyond an expected transient foreign body reaction.

Example 10. Pharmacokinetics of Celecoxib Loaded Silk-Fibroin Hydrogels after Intraarticular Injection

Methods

Celecoxib loaded silk-fibroin hydrogel formulations were prepared as previously described. Before dosing, animals were randomized into treatment groups. Rats will be dosed intra-articularly (I.A.), under isoflurane anesthesia, into the right knee joint on Day 1. At each timepoint (3, 7, 14, 28, 56, and 84 days) blood was collected from 4 animals per group and processed to serum using standard procedure. Serum was analyzed via LC/MS/MS to determine celecoxib concentrations.
