Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - Intranasal insulin
Other interventions - Placebo

Active comparator: DV001 - Recombinant human intranasal insulin formulation in a buffered solution of benzalkonium chloride and glycerol presented in multi-dose nasal spray devices with actuators (Pfeiffer) designed to deliver 100ul spray doses to nasal mucosa. The product is formulated at a dose strength of 1100 IU / mL (40mg/mL) manufacturing formulation. The product will be self administered by eligible participants as two 100 microlitre spray doses per nostril. Treatment will be administered daily for 7 consecutive days then on one day each week for 12 months. Participants will be followed until they develop diabetes or until 5 years after the last participant has been randomised (maximum period of follow up is expected to be 10 years.

Placebo comparator: Placebo - Placebo insulin carrier solution of benzalkonium chloride and glycerol presented in multi-dose nasal spray devices with actuators (Pfeiffer) designed to deliver 100ul spray doses to nasal mucosa. The product will be self administered by participants as two 100 microlitre spray doses per nostril. Treatment will be administered daily for 7 consecutive days then on one day each week for 12 months. Participants will be followed until they develop diabetes or until 5 years after the last participant has been randomised (maximum period of follow up is expected to be 10 years.
