PROPHYLACTIC PROTECTION AGAINST VIRAL INFECTIONS
The present disclosure provides methods for prophylactically treating a subject for viral infections comprising topically administering a ranpirnase composition. The disclosure also provides compositions that could be used for prophylactic treatment.
1 - 16 . (canceled)
17 . An intravaginal ring impregnated with a composition comprising a ribonuclease for conferring protection against viral infections, wherein the intravaginal ring is inserted into the vagina, and wherein the ribonuclease is a member of the ribonuclease A superfamily.
18 . The intravaginal ring of claim 17 , wherein the ribonuclease is selected from a group consisting of: ranpirnase, the '805 ranpirnase variant, Amphinase 2, and rAmphinase 2.
19 . The intravaginal ring of claim 17 , wherein the viral infection is caused by a virus selected from the group consisting of herpes simplex viruses (HSV), human papilloniaviruses (HPV), human immunodeficiency virus (HIV), hepatitis B virus, hepatitis C virus, and cytomegalovirus.
20 . The intravaginal ring of claim 17 , wherein the composition further comprises one or more dispersing agents.
21 . The intravaginal ring of claim 17 , wherein the ribonuclease is present in an amount from about 0.01% by weight to about 10% by weight, based on the total weight of the composition.
22 . The intravaginal ring of claim 17 , wherein the ribonuclease is present in an amount from about 0.1% by weight to about 1% by weight, based on the total weight of the composition.
23 . The intravaginal ring of claim 17 , wherein the ribonuclease is present in an amount from about 0.01% by weight to about 0.1% by weight, based on the total weight of the composition.
24 . The intravaginal ring of claim 17 , wherein the ribonuclease is present in an amount of about 1%, about 5%, or about 10%, by weight, based on the total weight of the composition.
25 . A method of conferring protection against viral infections comprising inserting an intravaginal ring into the vagina, wherein the intravaginal ring is impregnated with a composition comprising a ribonuclease, and wherein the ribonuclease is a member of the ribonuclease A superfamily.
26 . The method of claim 25 , wherein the ribonuclease is selected from a group consisting of: ranpirnase, the '805 ranpirnase variant, Amphinase 2, and rAmphinase 2.
27 . The method of claim 25 , wherein the viral infection is caused by a virus selected from the group consisting of herpes simplex viruses (HSV), human papilloniaviruses (HPV), human immunodeficiency virus (HIV), hepatitis B virus, hepatitis C virus, and cytomegalovirus.
28 . The method of claim 25 , wherein the composition further comprises one or more dispersing agents.
29 . The method of claim 25 , wherein the ribonuclease is present in an amount from about 0.01% by weight to about 10% by weight, based on the total weight of the composition.
30 . The method of claim 25 , wherein the ribonuclease is present in an amount from about 0.1% by weight to about 1% by weight, based on the total weight of the composition.
31 . The method of claim 25 , wherein the ribonuclease is present in an amount from about 0.01% by weight to about 0.1% by weight, based on the total weight of the composition.
32 . The method of claim 25 , wherein the ribonuclease is present in an amount of about 1%, about 5%, or about 10%, by weight, based on the total weight of the composition.
