Application Number:	US18/365,877
Patent Claims:	1. A method for providing effective contraception in a female patient over a 28-day period, comprising administering 24 scheduled daily oral doses of a pharmaceutical composition comprising from 2 mg to 6 mg of 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone to the female patient within a 24-day period, followed by a 4-day period wherein the daily oral dose is not administered, wherein the pharmaceutical composition does not comprise estrogen, and wherein administration of up to two non-consecutive scheduled daily oral doses may be delayed up to 24 hours from the scheduled daily administration, and the effective contraception is maintained when the up to two non-consecutive scheduled daily oral doses are delayed. 2. The method of claim 1, wherein the pharmaceutical composition comprises the 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone in a form such that the pharmaceutical composition has a solubility profile, wherein: (i) no more than 50% of the 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone initially present in the pharmaceutical composition is dissolved within 30 minutes; and (ii) at least 50% of the 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone initially present in the pharmaceutical composition is dissolved in a time range from three hours to four hours, when the pharmaceutical composition is subjected to an in vitro dissolution test according to the USP XXIII Paddle Method. 3. The method of claim 1, wherein a progesterone level of the female patient is lower than 5.04 ng/mL during the entire 28-day period. 4. The method of claim 3, wherein the progesterone level is 3 ng/mL or lower during the entire 28-day period. 5. The method of claim 1, wherein administration of one non-consecutive scheduled daily oral dose is delayed. 6. The method of claim 5, wherein two daily oral doses are administered to the female patient within 24 hours from the scheduled daily administration of the one non-consecutive scheduled daily oral dose. 7. The method of claim 1, wherein administration of two non-consecutive scheduled daily oral doses are delayed. 8. The method of claim 7, wherein two daily oral doses are administered to the female patient within 24 hours from each scheduled daily administration of the two non-consecutive scheduled daily oral doses. 9. The method of claim 1, wherein the method inhibits ovulation in the female patient. 10. The method of claim 2, wherein the method provides an improved bleeding profile in the female patient compared to orally administering a progestogen-only pharmaceutical composition that does not have the solubility profile. 11. The method of claim 10, wherein the improved bleeding profile comprises reduced incidences of unscheduled spotting and/or bleeding. 12. The method of claim 2, wherein at least 55% of the 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone initially present in the pharmaceutical composition is dissolved within 4 hours. 13. The method of claim 1, wherein the pharmaceutical composition comprises 4.0 mg of the 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone. 14. The method of claim 1, wherein the pharmaceutical composition comprises from 3.5 mg to 4.5 mg of the 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone.
