First SGLT1/2 inhibitor shows ‘spectacular’ phase 3 safety and efficacy in T2D



Also safe soon after acute heart failure decompensation

The other finding likely generalizable to SGLT2 inhibitors stems from the design of SOLOIST-WHF, which tested the efficacy and safety of starting sotagliflozin in patients with T2D as soon as they were stable after hospitalization for acute heart failure decompensation.

“Showing safety and efficacy when started in the hospital is pretty meaningful, because its tells patients that this drug is important and they should stay on it,” which should improve adherence, predicted Dr. Bhatt, who is also executive director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital in Boston. “That’s the ultimate treatment path to prevent patients from falling through the cracks” and failing to receive an SGLT2 inhibitor.

SOLOIST-WHF enrolled patients hospitalized for worsening heart failure who also required intravenous diuretic treatment but had become stable enough to transition to an oral diuretic and come off oxygen. During a median follow-up of just over 9 months (both SOLOIST-WHF and SCORED ended sooner than planned because of a change in drug company sponsorship), treatment with sotagliflozin cut the primary endpoint by a relative 33%, compared with placebo, and with an absolute reduction of 25 events per 100 patient-years for a number needed to treat of 4. Sotagliflozin produced a strikingly high level of treatment efficiency driven by the high event rate in these recently decompensated patients. The benefit also appeared quickly, with a significant cut in events discernible within 28 days.

Extrapolating this finding to the SGLT2 inhibitors is “not a huge leap of faith,” Dr. Bhatt said.

“There is a role for sotagliflozin in acute heart failure. It showed benefit in these high-risk, transition-phase patients,” said Dr. Wilcox.

Simultaneously with Dr. Bhatt’s presentation, results of SOLOIST-WHF and SCORED were published online in the New England Journal of Medicine.

The trials were sponsored initially by Sanofi, and more recently by Lexicon. Dr. Bhatt has received research funding from both companies, and also from several other companies. He also is an adviser to several companies. Dr. Wilcox has been a consultant to Boehringer Ingelheim and Medtronic.
