Eli Lilly tests dual amylin and tirzepatide therapy for obesity

CNBC reports Eli Lilly saw enhanced weight loss combining eloralintide with tirzepatide, alongside higher side-effect discontinuations.

The short version

  • Eli Lilly evaluated its experimental amylin-targeting drug eloralintide alongside tirzepatide in a Phase 2 trial for patients with obesity and Type 2 diabetes.[CNBC]
  • Patients receiving the highest combined dose achieved an average 23.3% weight loss over 48 weeks, compared to 14.8% for tirzepatide alone.[CNBC]
  • Treatment dropouts due to side effects ranged from 10.8% to 27% in the combined therapy groups, versus 2.9% for tirzepatide alone.[CNBC]
  • Phase 3 clinical trials intended to confirm the Phase 2 findings are scheduled to launch later this year.[CNBC]

Key facts

  • In a Phase 2 trial, patients on the highest-dose combination of eloralintide and tirzepatide averaged 23.3% weight loss at 48 weeks compared to 14.8% on tirzepatide alone.[CNBC]
  • Between 10.8% and 27% of combination trial participants discontinued treatment due to adverse side effects, compared with 2.9% receiving tirzepatide alone.[CNBC]
  • Phase 3 clinical trials to confirm the Phase 2 results are scheduled to begin later in the year.[CNBC]
  • Analyst David Risinger of Leerink Partners projects annual sales of eloralintide products will reach $23.2 billion by the end of 2035.[CNBC]

What remains uncertain

  • The Phase 2 study was relatively small, leaving final efficacy and tolerability to be verified in upcoming Phase 3 trials.[CNBC]
