Abstract

Among other things, the present disclosure relates to designed oligonucleotides, compositions, and methods thereof. In some embodiments, provided oligonucleotide compositions provide altered splicing of a transcript. In some embodiments, provided oligonucleotide compositions have low toxicity. In some embodiments, provided oligonucleotide compositions provide improved protein binding profiles. In some embodiments, provided oligonucleotide compositions have improved delivery. In some embodiments, provided oligonucleotide compositions have improved uptake. In some embodiments, the present disclosure provides methods for treatment of diseases using provided oligonucleotide compositions.

Claims (27)

1 . A method for identifying a chirally controlled oligonucleotide composition that has reduced complement activation relative to a reference oligonucleotide composition, the method comprising:

providing at least one chirally controlled oligonucleotide composition comprising a plurality of oligonucleotides;

assessing complement activation of each of the at least one chirally controlled oligonucleotide composition relative to the reference oligonucleotide composition; and

identify a chirally controlled oligonucleotide composition that displays reduced complement activation relative to the reference oligonucleotide composition;

wherein:

each of the at least one chirally controlled oligonucleotide composition is independently an oligonucleotide composition comprising a plurality of oligonucleotides of a particular oligonucleotide type which are structurally identical and is defined by:

1) base sequence;

2) pattern of backbone linkages;

3) pattern of backbone chiral centers; and

4) pattern of backbone phosphorus modifications;

which composition is chirally controlled in that it is enriched, relative to a substantially racemic preparation of oligonucleotides of the particular oligonucleotide type;

in the identified chirally controlled oligonucleotide composition, oligonucleotides of the plurality comprises 5 or more phosphorothioate internucleotidic linkages, wherein at least about 50% phosphorothioate internucleotidic linkages are Sp; and

the reference oligonucleotide composition is a substantially racemic preparation of oligonucleotides of the particular type.

2 . The method of claim 1 , wherein the reduced complement activation is observed in an assay that detects the presence, absolute level and/or relative level of C3a or Bb.

3 . The method of claim 1 , wherein the pattern of backbone chiral centers comprise at least one Rp and at least one Sp.

4 . The method of claim 3 , wherein the pattern of backbone chiral centers comprise Rp(Sp)m, wherein m is 2.

5 . The method of claim 4 , wherein the pattern of backbone chiral centers comprise Rp(Sp)m, wherein m is 3.

6 . The method of claim 4 , wherein the pattern of backbone chiral centers comprise Rp(Sp)m, wherein m is 4.

7 . The method of claim 4 , wherein the pattern of backbone chiral centers comprise Rp(Sp)m, wherein m is 5.

8 . The method of claim 4 , wherein the pattern of backbone chiral centers comprise Rp(Sp)m, wherein m is 6.

9 . The method of claim 4 , wherein the pattern of backbone chiral centers comprise Rp(Sp)m, wherein m is 7.

10 . The method of claim 4 , wherein the pattern of backbone chiral centers comprise Rp(Sp)m, wherein m is 8.

11 . The method of claim 4 , wherein the pattern of backbone chiral centers comprise RpSpSp.

12 . The method of claim 11 , wherein the pattern of backbone chiral centers comprise (Np)t(Rp)(Sp)m, wherein t is 1, m is 2, and each Np is independent Rp or Sp.

13 . The method of claim 12 , wherein the pattern of backbone chiral centers comprise SpRpSpSp.

14 . The method of claim 12 , wherein the pattern of backbone chiral centers comprise SpSpRpSpSp.

15 . The method of claim 4 , wherein oligonucleotides of the first plurality comprise one or more natural phosphate linkages.
