Although lowering side effects plays an important role in oral contraceptive compliance, one of the biggest challenges for patients is adhering to the daily schedule of the pill. Forgetting one to three pills per cycle is a frequent problem among 15-51% of users, particularly among adolescents. Lyndra Therapeutics has received a $13 million grant from the Bill & Melinda Gates Foundation and is setting out to remove the daily pill compliance challenge. The company is in early development of a monthly oral contraceptive to provide women with a discreet, noninvasive, reversible contraception option.
