  • Publication number: 20220323474
    Abstract: Provided herein is a novel method for creating fixed, non-antagonistic molar ratios of drugs in and around the bone environment for desired periods of time. This method enables treating bone and bone-related disease by administering a pharmaceutical composition comprising a bone-targeted therapeutic agent able to release a drug payload from the bone surface, in addition to a second therapeutic agent. Such methods are useful in the treatment of bone and bone-related diseases, such as cancer-induced bone disease, osteomyelitis and bone infection, bone pain and inflammatory bone disease, metabolic disease, as well as others.

  • Patent number: 11219603
    Abstract: The invention relates to the field of medicine and pharmaceuticals and particularly to a novel dosage form of an antitumor preparation, which ensures the hydrolytic and physical stability of said preparation, as well as to a method for producing a dosage form of this type. The stable dosage form is a lyophilizate comprising an etidronate-cytarabine conjugate or a pharmaceutically acceptable salt thereof, and a stabilizer, which is a divalent metal salt, in a molar ratio of stabilizer to conjugate of 1:1 to 20:1. A dosage form of this type ensures the hydrolytic and physical stability of the conjugate during long-term storage, and the stability of solutions of the conjugate for parenteral administration during clinical use.
