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.
1. A microbiota restoration therapy composition for oral delivery, comprising:
a processed human fecal preparation encapsulated in one or more capsules;
wherein the processed human fecal preparation is manufactured by:
collecting a fresh human fecal sample;
adding a diluent to the fresh human fecal sample to form a diluted sample;
wherein the diluent includes 30-90 g/L polyethylene glycol in saline;
mixing the diluted sample with a mixing apparatus;
filtering the mixture;
transferring a filtrate from the filtering step to a centrifuge tube;
centrifuging the filtrate to arrive at the purified intermediate;
lyophilizing the purified intermediate to form a plurality of lyophilized pellets; and
encapsulating the plurality of lyophilized pellets in the one or more capsules.
2. The microbiota restoration therapy composition of claim 1 , wherein the processed human fecal preparation comprises spore forming bacteria.
3. The microbiota restoration therapy composition of claim 1 , wherein the processed human fecal preparation consists essentially of spore forming bacteria.
4. The microbiota restoration therapy composition of claim 1 , wherein the processed human fecal preparation is free from non-spore forming bacteria.
5. The microbiota restoration therapy composition of claim 1 , wherein the processed human fecal preparation comprises non-spore forming bacteria.
6. The microbiota restoration therapy composition of claim 1 , wherein the processed human fecal preparation consists essentially of non-spore forming bacteria.
7. The microbiota restoration therapy composition of claim 1 , wherein the processed human fecal preparation is free from spore forming bacteria.
8. The microbiota restoration therapy composition of claim 1 , wherein the one or more capsules comprise hypromellose capsule.
9. The microbiota restoration therapy composition of claim 1 , further comprising banding the capsules.
10. The microbiota restoration therapy composition of claim 9 , wherein the banding material comprises hypromellose, an anionic copolymer based on methacrylic acid and methyl methacrylate, hypromellose phthalate, hypromellose acetate succinate, or combinations thereof.
