Treatment Method and Product for Uterine Fibroids using Purified Collagenase

Abstract

The invention relates to compositions and methods for treating uterine fibroids, wherein a uterine fibroid treatment agent comprising collagenase in an amount effective to cause shrinkage of uterine fibroids is injected or inserted into the uterine fibroid.

1 . A method for the treatment of uterine fibroids in a patient comprising administering to the uterine fibroid a composition comprising about 0.06 to about 1 mg of  Clostridium histolyticum  collagenase per 1 cm3 uterine fibroid tissue. 
     
     
         2 . The method of  claim 1 , wherein said composition is delivered through a delivery channel into said fibroid, wherein the delivery channel is in a needle, syringe, cannula, catheter or jet injector. 
     
     
         3 . The method of  claim 1 , wherein the collagenase is a mixture of collagenase I and collagenase II. 
     
     
         4 . The method of  claim 1 , wherein about 0.1 mg to about 0.8 mg collagenase is administered per cm3 of tissue to be treated. 
     
     
         5 . The method of  claim 1 , wherein about 0.2 mg to about 0.6 mg collagenase is administered per cm3 of tissue to be treated. 
     
     
         6 . The method of  claim 1 , wherein said composition is injected or inserted into said fibroid under image guidance, wherein said image is a scope image, an MRI image, an ultrasound image, or a fluoroscopic image. 
     
     
         7 . The method of  claim 1 , wherein said composition further comprises a chemical ablation agent, a non-steroidal anti-inflammatory drug, an oral contraceptive, a GnRH agonist, an antiprogestogen, or a selective progesterone receptor modulator. 
     
     
         8 . The method of  claim 1 , wherein said composition is a solid dosage form having a largest dimension between 1 mm and 20 mm. 
     
     
         9 . The method of  claim 1 , wherein the composition further comprises a viscosity adjusting agent is present in an amount effective to provide a viscosity ranging from 10,000 centipoise to 50,000 centipoise. 
     
     
         10 . The method of  claim 1 , wherein the composition provides sustained release of an amount of said collagenase sufficient to treat said uterine fibroids. 
     
     
         11 . A method for the treatment of uterine fibroids in a patient, comprising administering into the uterine fibroid a composition comprising 0.25-2.0 mg/mL collagenase from  Clostridium histolyticum.    
     
     
         12 . The method of  claim 11 , wherein said composition is delivered through a delivery channel into said fibroid, wherein the delivery channel is in a needle, syringe, cannula, catheter or jet injector. 
     
     
         13 . The method of  claim 11 , wherein the collagenase is a mixture of collagenase I and collagenase II. 
     
     
         14 . The method of  claim 11 , wherein said composition comprises about 0.25 mg/mL collagenase from  Clostridium histolyticum.    
     
     
         15 . The method of  claim 11 , wherein said composition comprises about 0.5 mg/mL collagenase from  Clostridium histolyticum.    
     
     
         16 . The method of  claim 11 , wherein said composition comprises about 1.0 mg/mL collagenase from  Clostridium histolyticum.    
     
     
         17 . The method of  claim 11 , wherein said composition comprises about 2.0 mg/mL collagenase from  Clostridium histolyticum.    
     
     
         18 . The method of  claim 11 , wherein said composition is injected or inserted into said fibroid under image guidance, wherein said image is a scope image, an MRI image, an ultrasound image, or a fluoroscopic image. 
     
     
         19 . The method of  claim 11 , wherein said composition further comprises a chemical ablation agent, a non-steroidal anti-inflammatory drug, an oral contraceptive, a GnRH agonist, an antiprogestogen, or a selective progesterone receptor modulator. 
     
     
         20 . The method of  claim 11 , wherein said composition is a solid dosage form having a largest dimension between 1 mm and 20 mm. 
     
     
         21 . The method of  claim 11 , wherein the composition further comprises a viscosity adjusting agent is present in an amount effective to provide a viscosity ranging from 10,000 centipoise to 50,000 centipoise. 
     
     
         22 . The method of  claim 11 , wherein the composition provides sustained release of an amount of said collagenase sufficient to treat said uterine fibroids.
