Additional safety requirements regarding effect of NCE on cardiac rhythm a new “requirement”- studies still to be done for NDA
Manufacturing process improvements underway - advancement from pilot scale production to development of commercial process – must be low cost!

New Contraceptive Methods Needed
While tremendous success can be achievedby expanding access to existing methods,some additional methods would likely haveimmediate application if they were of low cost:
1. Non-hormonal, non-steroidal or non-estrogen or progestin oral contraceptives
2. New long-acting non-DMPA injectables in novel delivery systems
3. Biodegradable implants4. Non-surgical methods of male and female
sterilization5. Novel dual protection methods
