Abstract: Abstract Objective Our objective was to investigate willingness to pay (WTP) for biphasic insulin aspart 30/70 (BIAsp 30) in patients with type 2 diabetes mellitus (T2DM) in India. Methods A multicenter, prospective, non-interventional, preference study was conducted that assessed WTP for BIAsp 30 in an insulin pen (FlexPen® or Penfill® device) in patients in India with T2DM previously treated with biphasic human insulin (BHI) in vials and believed to be able to pay for treatment. The primary endpoint was the proportion of patients willing to continue to pay for BIAsp 30 after 12 weeks’ treatment. Secondary endpoints included the change from baseline in treatment and device satisfaction and patient preferences for treatment attributes as assessed by a nested discrete-choice experiment. Results Overall, 54.9% (n = 277/505) of participants were male; the mean age was 56.4 years; diabetes duration was 10.9 years; 63.8% had a body mass index ≥ 25 kg/m2; > 75% had an annual household income > 150,000 Indian rupees (INR). After 12 weeks’ treatment, 96.4% of patients were willing to pay for BIAsp 30. Mean treatment and device satisfaction significantly improved from baseline (p
