  • Publication number: 20210060143
    Abstract: It is an object of the present disclosure to provide a formulation for injectable and topical collagenase, which will have extended residence time for the drug at the therapeutic targeted area for the indication being treated. It is a further object of the disclosure to provide a slow release formulation for collagenase, which is compatible with the active ingredient and does not adversely affect its activity. Still a further object of the disclosure is to provide an injectable formulation for collagenase which can be effectively administered to a patient with a small size needle without exhibiting pre-gelation, which would interfere with the ability to deliver the required dose for treatment. Still a further object of the disclosure is to provide a water-based topical formulation for collagenase which will be more compatible with other topically used medications to achieve better results.

  • Publication number: 20210040468
    Abstract: The present invention provides a method for producing a drug product comprising a combination of highly purified collagenase I and collagenase II from Clostridium histolyticum. The method utilizes an improved medium for the cultivation of Clostridium histolyticum which includes a non-meat-derived (i.e., non-mammalian) peptone or vegetable peptone. The method includes one or more of: (1) reducing glucose content in the meat-free or vegetable-derived media; and (2) increasing the salt concentration in the meat-free or vegetable-derived media. Also provided is a drug product which includes collagenase I and collagenase II at an optimized fixed mass ratio, and which has a purity of greater than at least 95%.
