Abstract:
AS-oIigonucleotides are delivered in microsphere form in order to induce dendritic cell tolerance, particularly in the non-obese-diabetic (NOD) mouse model. The microspheres incorporate antisense (AS) oligonucleotides. A process includes using an antisense approach to reverse an autoimmune diabetes condition in NOD mice in vivo. The oligonucleotides are targeted to bind to primary transcripts CD40, CD80, CD86 and their combinations.
Abstract:
The present invention relates to polymeric derivatives, which can be conjugated to an amino-containing drug to improve its in vivo properties. The polymeric derivative can subsequently be released to yield the drug in its native form. Methods of preparing and using these polymeric derivatives and drug conjugates are described.
Abstract:
The present disclosure is related to microparticle compositions, in which the microparticles are made of nucleic acids and non-polymeric cations, which are suitable for administration to moist or aqueous target locations (e.g., the lung tissue), where the substantially spherical nucleic acid microparticles release the nucleic acids through dissolution, allowing the released nucleic acids to freely interact with the target cells.
Abstract:
Compositions of spherical insulin particles having improved pulmonary application potentials and methods of forming and using these compositions are disclosed in the present application. In one clinical trial with 30 healthy male human subjects, no coughing was observed upon a single pulmonary administration of the spherical insulin particles at an insulin dose of 6.5 mg, nor during the 10-hour post dosing period.
Abstract:
The present disclosure relates to compositions of methods of making and compositions small compositions of particles of an active agent. In accordance with the method of production, the active agent is dissolved in an aqueous or aqueous-miscible solvent containing a dissolved phase-separation enhancing agent (PSEA) to form a solution in a single liquid phase. The solution is subjected to a liquid-solid phase separation to cause the active agent to form small spherical particles that are substantially amorphous or non-crystalline and are injectable through fine bore needles at high concentrations. The particles exhibit the pharmacokinetic and pharmacodynamic properties of the active agent. The disclosure has special application for higher molecular weight proteins such as antibodies.
