Application Number:	16/677,831
Patent Claims:	1. A method for the treatment of one or more symptoms of vulvo-vaginal atrophy (VVA) comprising: administering a vaginal suppository intravaginally once daily to a female subject having VVA, the vaginal suppository comprising a liquid composition comprising 4 .mu.g estradiol and a solubilizing agent comprising a medium chain oil; wherein the administering provides, in a plasma sample from the subject at day 14 following once daily administration for 14 days, one or more parameters selected from the group consisting of: 1) an unadjusted estradiol C.sub.max value of 4.8 pg/mL.+-.2.3 pg/mL, 2) an unadjusted estradiol C.sub.avg[0-24] value of 3.6 pg/mL.+-.1.8 pg/mL, 3) an unadjusted estrone C.sub.max value of 16.0 pg/mL.+-.5.5 pg/mL, and 4) an unadjusted estrone C.sub.avg[0-24] value of 13.6 pg/mL.+-.4.8 pg/mL. 2. The method of claim 1, wherein the viscosity of the liquid composition is from about 50 cps to about 1000 cps at 25.degree. C. 3. The method of claim 1, wherein the treatment is effective at or within two weeks after administration of the first vaginal suppository. 4. The method of claim 1, wherein estradiol is the only active pharmaceutical ingredient in the vaginal suppository. 5. The method of claim 1, wherein the medium chain oil comprises at least one C6-C12 fatty acid or a monoglyceride, diglyceride, or triglyceride thereof. 6. The method of claim 1, wherein the liquid composition further comprises a thickening agent. 7. The method of claim 1, wherein a vaginal suppository is administered to the subject once daily for two weeks and twice weekly thereafter. 8. The method of claim 7, wherein the twice weekly administration occurs every three to four days. 9. The method of claim 1, wherein the subject remains ambulatory for a period of time beginning about 5 minutes after administering a vaginal suppository and ending about 4 hours after administering the vaginal suppository. 10. The method of claim 1 wherein the symptoms of VVA are selected from the group consisting of vaginal dryness, dyspareunia, vaginal or vulvar irritation, burning or itching, dysuria, and vaginal bleeding associated with sexual activity. 11. The method of claim 10, wherein the treatment decreases the severity of vaginal dryness, the severity of vulvar or vaginal itching, the severity of dyspareunia, or a combination thereof at or within two weeks after administration of the first vaginal suppository. 12. The method of claim 11, wherein the treatment decreases severity of dyspareunia from baseline over a treatment period, wherein mean reduction in dyspareunia severity over the treatment period is from about 15% to about 20% greater than that obtained with a placebo. 13. The method of claim 1, wherein the liquid composition does not comprise a hydrophilic gel-forming bioadhesive agent. 14. A method for the treatment of one or more symptoms of vulvo-vaginal atrophy (VVA) comprising: administering a vaginal suppository intravaginally once daily to a female subject having VVA, the vaginal suppository comprising a liquid composition comprising a 10 .mu.g estradiol and a solubilizing agent comprising a medium chain oil; wherein the administering provides, in a plasma sample from the subject at day 14 following once daily administration for 14 days, one or more parameters selected from the group consisting of: 1) an unadjusted estradiol C.sub.max value of 7.3 pg/mL.+-.2.4 pg/mL, 2) an unadjusted estradiol C.sub.avg[0-24] value of 4.6 pg/mL.+-.2.3 pg/mL, 3) an unadjusted estrone C.sub.max value of 23.9 pg/mL.+-.13.4 pg/mL, and 4) an unadjusted estrone C.sub.avg[0-24] value of 19.3 pg/mL.+-.10.2 pg/mL. 15. The method of claim 14, wherein the viscosity of the liquid composition is from about 50 cps to about 1000 cps at 25.degree. C. 16. The method of claim 14, wherein the treatment is effective at or within two weeks after administration of the first vaginal suppository. 17. The method of claim 14, wherein estradiol is the only active pharmaceutical ingredient in the vaginal suppository. 18. The method of claim 14, wherein the medium chain oil comprises at least one C6-C12 fatty acid or a monoglyceride, diglyceride, or triglyceride thereof. 19. The method of claim 14, wherein the liquid composition further comprises a thickening agent. 20. The method of claim 14, wherein a vaginal suppository is administered to the subject once daily for two weeks and twice weekly thereafter. 21. The method of claim 20, wherein the twice weekly administration occurs every three to four days. 22. The method of claim 14, wherein the subject remains ambulatory for a period of time beginning about 5 minutes after administering a vaginal suppository and ending about 4 hours after administering the vaginal suppository. 23. The method of claim 14, wherein the symptoms of VVA are selected from the group consisting of vaginal dryness, dyspareunia, vaginal or vulvar irritation, burning or itching, dysuria, and vaginal bleeding associated with sexual activity. 24. The method of claim 23, wherein the treatment decreases the severity of vaginal dryness, the severity of vulvar or vaginal itching, the severity of dyspareunia, or a combination thereof at or within two weeks after administration of the first vaginal suppository. 25. The method of claim 24, wherein the treatment decreases severity of dyspareunia from baseline over a treatment period, wherein mean reduction in dyspareunia severity over the treatment period is from about 30% to about 35% greater than that obtained with a placebo. 26. The method of claim 14, wherein the liquid composition does not comprise a hydrophilic gel-forming bioadhesive agent.
