MICROBIOTA RESTORATION THERAPY (MRT) COMPOSITIONS AND METHODS OF MANUFACTURE
Microbiota restoration therapy (MRT) compositions (e.g., oral MRT compositions) and methods for manufacturing MRT compositions are disclosed. An example method for manufacturing an MRT composition may include collecting a stool sample, purifying the stool sample to form a purified sample, stabilizing the purified sample to form a stabilized sample, converting the stabilized sample to a solid, adding one or more additives and/or excipients to the solid to form a treatment composition, and encapsulating the treatment composition.

21 . A microbiota restoration therapy method, comprising orally administering to a subject in need thereof a microbiota restoration therapy composition comprising a lyophilized material comprising fecal microbiota and a lyophilization excipient comprising polyethylene glycol and one or more selected from trehalose, sucrose, and glycerin.
22 . The method of claim 21 , wherein the lyophilization excipient comprises polyethylene glycol and two or more selected from trehalose, sucrose, and glycerin.
23 . The method of claim 21 , wherein the lyophilization excipient comprises polyethylene glycol and trehalose, sucrose, and glycerin.
24 . The method of claim 21 , wherein the lyophilization excipient comprises polyethylene glycol 3550, trehalose, sucrose, and glycerin.
25 . The method of claim 21 , wherein the microbiota restoration therapy composition is prepared by a process comprising:
processing a human donor fecal sample to obtain a fecal microbiota composition; and
lyophilizing the fecal microbiota composition with a lyophilization excipient to obtain a lyophilized material, wherein the lyophilization excipient comprises polyethylene glycol and one or more selected from trehalose, sucrose, and glycerin.
