Luna Diabetes develops a method of insulin delivery for insulin pen users; its flagship product, Luna, pairs a small insulin patch pump with a closed-loop algorithm to automate insulin delivery during sleep and support users across the day. The product is designed to provide automation without requiring a switch to a full-time insulin pump. The company is based in San Diego, CA. Luna raised $23.6M in a Series A financing. It intends to use the funds to advance regulatory submissions, conduct clinical studies, build manufacturing capacity, and expand clinical and market access programs.
