Description

THERAPEUTIC COMPOSITIONS FOR OSTEOINDUCTION

TECHNICAL FIELD

The present invention relates to the field of osteoinduction (bone growth). Specifically, the present invention relates to novel therapeutic formulations comprising the administration of bone orphogenetic proteins and a Vitamin D compound, resulting in synergistic bone growth.

BACKGROUND OF THE INVENTION In healthy individuals bone growth generally proceeds nor¬ mally and fractures heal without the need for pharmacologic intervention. Nonetheless, in certain instances bones may be weakened or may fail to heal properly. For example, healing may proceed slowly in the elderly and in patients undergoing treatment with corticosteroids, such as transplant patients and those being treated for chronic lung disease. Another example is osteopor¬ osis. Osteoporosis is an abnormal loss of bony tissue often occurring in post- enopausal woman and elderly men. The disorder increases the risks of small fractures occurring in the bones, particularly the spine. At present, osteoporosis is treated mainly by supplements of calcium, vitamin D, estrogen, or calcitonin, a hormone which controls the body's use of calcium. Unfortunately, these treatments are merely preventative against the further loss of bone. There is a need in the art for treat¬ ments that go beyond the prevention of bone loss and promote bone formation and/or reverse bone loss.

(1989) "Bone Morphogenic Proteins and Vitamin D", Nutrition Reviews. Vol. 47, pp. 364-366 concludes that Vitamin D in the diet prevents the loss of the osteoinductive activity of bone matrix.

Turner, R. T., J. Farley, J. J. Vandersteenhoven, S. Epstein, N. H. Bell, and D. J. Baylink, (1988) "Demonstration of Reduced Mitogenic and Osteoinductive Activities in Demineralized Allo- geneic Bone Matrix from Vitamin D-deficient Rats", The Journal of Clinical Investigation. Inc.. Vol. 82, pp. 212-217, discloses the implantation of demineralized bone matrix from Vitamin D-deficient rats into normal rats. The demineralized bone matrix from Vitamin D-deficient rats did not promote osteoinduction as effectively as demineralized bone matrix from normal rats. Sampath, T. K., S. eintraub, and A. H. Reddi, (1984) "Extra¬ cellular Matrix Proteins Involved in bone Induction are Vitamin D Dependent", Biochemical and Biophysical Research Communications. Vol. 124, pp. 829-835, discloses a study involving implantation of demineralized bone matrix from normal rats and demineralized bone matrix from rachitic rats wherein the rachitic bone matrix did not induce bone growth while the normal bone matrix did. The study concluded that these results demonstrate that Vitamin D is necessary to produce bone inductive proteins in the bone matrix of a living rat.

A preferred method of obtaining the osteoinductive extract is as follows:

Snip the skin at the ankles of a 7-8 week old Long-Evans rat (Charles River laboratories, Wilmington, MA). Remove both tibiae 11 - and place in cold water. Rinse the bone with distilled water to remove non-osseous tissue (tissue other than bone). Allow the bone to air dry. Grind the bones by placing in an Osterizer (Oster Commercial, Milwaukee, WI) blender with water and ice. With the blender set at "liquefy" speed, continue to add bone. Allow the blended material to settle for a few minutes. Decant the liquid layer. Place the solid layer on a stirring plate and add distilled water to wash. Continue washing until the distilled water washes clear. Once the distilled water is clear, add ice and stir. Add 1 ml of ImM of phenylmethylsulfonyl fluoride (PMSF). Wash for 1 hour adding ice frequently. Repeat with a second water wash. Place the sample in an ice water bath on a stirring plate. Defat with absolute ethanol, then defat twice with ethyl ether. Spread bone material onto glass petri dishes. Allow the bone chips to air dry overnight.

Weigh the bone chips following the overnight drying. Using a sieve (U.S.A. Standard Sieve Series, Newark Wire Cloth Co., Newark, N.J.; sieve #40 retains particles greater than 425 μm and sieve #170 retains particles greater than 90 μm), isolate the bone particles in the 90-425um range. Grind any particles greater than 425μm in a MicroMill (Scienceware Bel-Art Products, Pequannock, NJ) for 1 minute adding dry ice to the bone particles to keep the material cold. Repeat the sieving and MicroMill grinding steps of the greater than 425μm particles until the amount of total recovery is greater than 2/3 of the initial weight of the bone. Store the particles at 4°C until the next step. Weigh the particles isolated thus far. For each gram of particles, add 25 ml of 0.6N HC1. Stir vigorously at 4^*C for 2 hours. After 2 hours, stop stirring and allow the particles to settle. Decant the HC1. Add fresh 0.6N HC1 and stir again for 2 hours. Decant the HC1 and add fresh 0.6N HC1 a third time and stir for two hours. Decant the HC1 and rinse with distilled water. Using litmus paper, check the pH of the water for the presence of HC1. Continue rinsing with distilled water until the pH is between about 5 and 5.5. Rinse the bone particles with ethanol three times. Swirl, allow to settle, and remove the supernatant. Rinse the bone particles with ethyl ether three times as above. Dry overnight in glass plates. The dried bone particles are referred to as "acid demineralized bone particles". - 12 -

The acid demineral zed bone particles are deproteinized as follows: Weigh the material following the overnight drying. For each gram of material, add a solution of 30 ml 4M guanidine-HCl, lOmM Tris and l.OmM PMSF pH 6.4 to the bone material in a beaker. 5 Extract for 16 hours at 4^* with vigorous stirring. Following the 16 hour extraction, cease stirring and allow the material to settle. Pour off the guanidine solution and save. Extract the material a second time for 6-7 hours using fresh guanidine-HCl solution. Following the extraction, pour off the solution and 10 combine with the previously saved solution. The bone particles are now demineralized and deproteinized.

Dialyze the saved guanidine-HCl solution against distilled H₂0 at 4°C using 50 mm dialysis tubing (3500 molecular weight cutoff). Following dialysis, lyopholize the material and resolu- 15 bilize the lyophilized material in 4M Urea-0.05M Tris-O.IM NaCl, pH 7.4. Mix the solubilized material in a conical centrifuge tube with Heparin-Agarose and mix overnight on a rotator at 4°C. Pour the Heparin-Agarose slurry into a column. Wash with 1 column volume 4M urea, 0.05M Tris, 0.1M NaCl, pH 7.4 buffer. Collect the 20 fraction. Wash with 3 column volumes of 4M urea, 0.05M Tris, 0.2M NaCl, pH 7.4 buffer. Step off the material with 3 column volumes of 4M urea, 0.05M Tris, 0.75M NaCl, pH 7.4. Concentrate this sample in a 50 ml Amicon concentrator (Amicon Corp., Danvers, MA) with filter (10,000 molecular weight cut off) to about 4-5ml. 25 Assay for protein concentration using BCA (bicinchoninic acid) Protein Assay Reagent (Pierce, Rockford, IL) and dialyze (3500 molecular weight cutoff dialysis tubing) in 4M guanidine-0.01 M Tris pH 7.4. Load material on Sephacryl S-200 column and collect fractions. The fractions containing the major protein peak are 30 dialyzed against 1M acetic acid and assayed for activity.

Active fractions from the gel filtration are combined and dialyzed against three changes of 6M urea, 25mM Na acetate, pH 4.6. The dialysate is loaded onto a column of carboxymethyl- sepharose (CM-Sepharose) equilibrated with the same buffer. The 35 column is washed with 6M urea, 25mM Na acetate, pH 4.6 and activity eluted using a 0 - 0.5M NaCl gradient. Fractions are analyzed for protein concentration and sodium dodecyl sulfate gel electrophoresis. The activity located in the seven fractions before and after the beginning of the major protein peak are 13 - pooled for further purification.

The pooled CM-Sepharose fractions are dialyzed three times for 24 hours each against 1% acetic acid. The dialysate is lyophilized to dryness and the protein pellet dissolved into 30 ml of 6M urea, 0.5M NaCl, 25mM Na phosphate, pH 7.4. The sample is applied on a column of chelating Sepharose charged with zinc and equilibrated with the above buffer. The column is washed with the above buffer and then eluted with a gradient from 6M urea, 0.5M NaCl, 25mM Na phosphate, pH 7.4 to 6M urea, 0.5M NaCl, 25mM Na acetate, pH 4.6. Aliquots of each fraction are labeled with ¹²⁵I and analyzed by SDS gel electrophoresis. Aliquots (100 μl) of each fraction are combined with 400 μl of elution buffer, dialyzed against 1% acetic acid and assayed for activity. Highly purified molecular weight range (M_r) 25-40 kD peptides are assayed in the bone induction assay.

A safe and effective amount of osteoinductive extract is dosed in combination with a Vitamin D compound. For purposes of systemic treatment, the osteoinductive extract dosed preferably comprises at least one BMP in an amount from about 1 pg to about 100 μg, preferably from about 1 ng to about 10 μg, more preferably from about 10 ng to about 2.5 μg.

For purposes of regional treatment, the osteoinductive extract dosed preferably comprises at least one BMP in an amount from about 1 pg to about 100 μg, more preferably from about 1.5 μg to about 90 μg, preferably from about 1.8 μg to about 75 μg, more preferably from about 2.0 μg to about 50 μg, more preferably still from about 2.2 μg to about 25 μg, more preferably from about 2.3 μg to about 10 μg, most preferably from about 2.5 μg to about 5 μg. Preferably the dose range is at least about 2.5 μg. Preferably, doses are administered over a 1 day to 6 month period, more preferably from about 1 week to about 1 month. Preferably doses are administered from about once per month to about 5 times per day, more preferably from about once per week to about once per day. Pharmaceutically Acceptable Carrier

The Vitamin D compound, osteoinductive extract, or BMP may be administered via a pharmaceutically acceptable carrier. The term "pharmaceutically-acceptable carrier", as used herein, means one - 14 - or more compatible solid or liquid filler diluents or encapsu¬ lating substances which are suitable for administration to a human or lower animal. The term "compatible", as used herein, means that the components of the pharmaceutical compositions are capable of being commingled with the compound(s) of the subject invention, and with each other in a manner such that there is no interaction which would substantially reduce the pharmaceutical efficacy of the pharmaceutical composition under ordinary usage situations. Pharmaceutically-acceptable carriers must, of course, be of sufficiently high purity and sufficiently low toxicity to render them suitable for administration to human or lower animal being treated.

Some examples of substances which can ssr^e as pharmaceuti¬ cally-acceptable carriers are sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives, such as sodium carboxymethylcellulose, ethylcellulose, cellulose acetate; powdered tragacanth; malt; gelatin; talc; stearic acid; magnesium stearate; calcium sulfate; vegetable oils such a peanut oil, cottonseed oil, sesame oil, olive oil, corn oil and oil of theobroma; polyols such as propylene glycol, glycerine, sorbitol, mannitol, and polyethylene glycol; sugar; alginic acid; pyrogen-free water; isotonic saline; phosphate buffer solutions; cocoa butter (suppository base); emulsifiers, such as the Tweens*; as well as other non-toxic compatible substances used in pharmaceutical formulations. Wetting agents and lubricants such as sodium lauryl sulfate, as well as coloring agents, flavoring agents, excipients, tableting agents, stabilizers, antioxidants, and preservatives, can also be present. Other compatible pharmaceutical additives and actives (e.g., NSAI drugs; pain killers; muscle relaxants) may be included in the pharmaceutically-acceptable carrier for use in the compositions of the present invention. For example, art-known local anesthetics may be included in the pharmaceutically-accept¬ able carrier (e.g., benzyl alcohol; Novocaine*; lidocaine). Additional examples of carriers include collagen, deminer¬ alized bone particles, ceramic and metallic implant materials, collagen membrane and bone grafts (isogenic or allogenic).

The choice of a pharmaceutically-acceptable carrier to be used in conjunction with the compounds of the present invention is - 15 - determined by the way the compound is to be administered. The preferred modes of administering the compounds of the present invention are by injection, oral administration, topical-oral administration, and nasopharyngeal administration or a combination of modes (i.e., osteoinductive extract via injection and Vitamin D compound via oral administration). If the compound is to be injected, the preferred pharmaceutically-acceptable carrier is sterile, physiological saline. Suitable pharmaceutically- acceptable carriers for oral administration include those suited for tablets, and capsules. Suitable pharmaceutically-acceptable carriers for topical-oral administration include those suited for pastes, gels, and liquids. Suitable pharmaceutically-acceptable carriers for nasopharyngeal administration include those suited for drops, sprays, mists and powders. A separate pharmaceutically-acceptable carrier may be used in conjunction with each active component of the present invention or a single pharmaceutically-acceptable carrier may be employed in conjunction with a mixture of the active components of the present invention. In either case, the pharmaceutically-acceptable carrier is used at a concentration sufficient to provide a practical size to dosage relationship. The pharmaceutically- acceptable carriers, in total, may comprise from about 0.1% to about 99.99999% by weight of the pharmaceutical compositions of the present invention, preferably from about 50% to about 99.999%, and most preferably from about 75% to about 99.9%.
