Luna is sleep-only automation for people who take insulin with pens. You put it on at bedtime and take it off when you wake. Overnight, it reads your CGM and delivers small boluses of your rapid-acting insulin.

Luna is for adults who take insulin with pens, use a CGM, manage their days well, and choose not to wear a pump around the clock. If you go to bed higher than you’d like because you’re worried about going low, Luna may be right for you.

Nights are hard to predict. Dinner, exercise, stress, and illness all change what happens overnight, and a basal dose taken hours earlier can’t adjust to any of it. Once you’re asleep, you can’t see a number or respond to it either.

That combination is why the night is so hard: 79% of adults with type 1 diabetes on multiple daily injections and CGM say diabetes interrupts their sleep.¹

Luna is sleep-only automation. Yes, it’s an insulin pump, but not a 24/7 one. It works alongside your pens instead of replacing them. You wear it while you sleep and take it off when you wake.

No. Luna is built for people who have chosen pens and want to keep them. Only 5% of adults on multiple daily injections and CGM say they are highly or extremely likely to start a pump within the next 12 months.² Pen users stay in charge of their days, and Luna steps in at night.

At bedtime, you fill Luna from your rapid-acting insulin pen and put it on. While you sleep, Luna uses your CGM readings to deliver small doses of insulin if you need them. In the morning, you take it off and go about your day as usual.

Yes. Luna does not replace your long-acting basal insulin. Overnight, its small boluses cover glucose rises. Separately, Luna helps you and your clinician find the right basal dose over time.

You don’t have to change your insulin or pens. Luna is filled from the rapid-acting insulin pen you already use, and you keep using your pens during the day.

Luna is being developed to work with FDA-cleared iCGM sensors, but the list of supported sensors isn’t confirmed yet.

No. Luna works only while you sleep. Mealtime and daytime doses stay with your pen.

You may not need anything for your days. Luna leaves them exactly as they are. The question is your nights: how often you wake to an alarm, treat a low, or wake up high. Nearly a third of people go to bed with their glucose high on purpose to avoid going low overnight.³ Luna is designed for those hours and only those hours.

A1c is an average over about three months. It can look fine while nights swing between lows and waking up high, because the two partly cancel out. Overnight time in range shows the night on its own, and it is worth asking your care team about.

We are initially focused on adults, and we hope to make Luna available for people 14 and over.

We are launching in the US first. Other countries come after that.

Get in touch. Anything about how Luna works or whether it suits how you manage, we can answer today. Our Learn pages cover the overnight hours in more depth.

It is too early to say. We have not set a price, and there is no coverage decision yet. Luna is an investigational device and is not yet available. We’ll share pricing and coverage as soon as we can.

There’s no coverage decision yet. Coverage for a new device is negotiated with payors after clearance, using clinical evidence we’re generating.
