Patent number: 11938222Abstract: The present application relates to a pregabalin sustained release composition, comprising: (a) an active ingredient; (b) a matrix-forming agent; (c) a swelling agent; (d) a gelling agent; and optionally a filler. The pregabalin sustained release composition provided in the present application can rapidly swell in volume when exposed to aqueous medium until exceeding the dimeter of human gastric pyloric (13 mm). It thereby prolongs the gastric emptying time to increase the retention time of pregabalin in the stomach and enhances absorption of pregabalin in the small intestine and ascending colon. Moreover, the pregabalin sustained release composition provided herein achieves a sustained release for 24 h, which allows QD (once a day) administration, reduces administration number, and improves patient compliance.Type: GrantFiled: June 12, 2019Date of Patent: March 26, 2024Assignee: BEIJING TIDE PHARMACEUTICAL CO., LTD.Inventors: Zhaolu Zhu, Yun Wu, Di Lu, Yanping Zhao, Liying Zhou, Yanan Liu

Publication number: 20210388065Abstract: The present invention provides recombinant monoclonal antibodies that bind to the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2 or COVID-19) spike protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that bind to SARS-CoV-2 spike protein. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing SARS-CoV-2 activity, thus providing a means of treating or preventing COVID-19 infection in humans. In some embodiments, the invention provides for a combination of one or more antibodies that bind to the SARS-CoV-2 spike protein for use in treating COVID-19 infection. In certain embodiments, the one or more antibodies bind to distinct non-competing epitopes comprised in the receptor binding domain of the SARS-CoV-2 spike protein.Type: ApplicationFiled: April 15, 2020Publication date: December 16, 2021Applicants: ACTIVE MOTIF SHANGHAI LIMITED, SHANGHAI PUBLIC HEALTH CLINICAL CENTER, FUDAN UNIVERSITY, SHANGHAI PUBLIC HEALTH CLINICAL CENTERInventors: Yanan LU, Fei LAN, Jianqing XU, Xi ZHAO, Longfei DING, Yongheng WANG, Jinkai WAN, Shenghui XING, Joseph FERNANDEZ

Publication number: 20200130065Abstract: A method for producing a water-atomized prealloyed powder with high cold press formability, includes the following steps: (a) preparing a ?400 mesh semi-finished prealloyed powder; (b) controlling the semi-finished prealloyed powder to have a moisture content of 1 wt % to 2 wt % and an oxygen content of 0.6 wt % to 0.8 wt %, and then drying in a vacuum drying oven at 100° C. for 90 minutes to 120 minutes, so that a preliminary bond is produced between powder particles; and (c) reducing, annealing, crushing, and sieving an initially bonded powder particle. The powder is changed from a spheroidal shape to more complex shapes such as “rice ear shape”, “grape shape”, and “satellite powder”, which greatly improves the cold press formability of the prealloyed powder; the method only performs simple surface modification of the powder without changing other properties, and has wide applicability.Type: ApplicationFiled: December 17, 2019Publication date: April 30, 2020Inventors: Xiaofeng LI, Anding FAN, Dagen DOU, Yanan LU, Wenwen AN
