ALN-4324 for insulin sensitivity in adults with type 2 diabetes

A Randomized, Double-blind, Placebo-controlled Study Investigating the Effect of ALN-4324 on Insulin Sensitivity in Patients With Type 2 Diabetes Mellitus

PHASE2 · Alnylam Pharmaceuticals · NCT07465224

This study will test whether a single dose of ALN-4324 improves whole-body insulin sensitivity in adults with type 2 diabetes who are on stable metformin therapy.

What this trial studies

This is a Phase 2 interventional trial testing a single dose of ALN-4324, an investigational siRNA-based medicine, versus placebo in adults with type 2 diabetes. Participants must meet BMI and HbA1c ranges and remain on a stable dose of metformin. After dosing, whole-body insulin sensitivity is measured and compared between the ALN-4324 and placebo groups. Safety and laboratory measures are monitored to identify any treatment-related effects.

Who should consider this trial

Good fit: Adults with confirmed type 2 diabetes, BMI between 25 and 39.9 kg/m^2, HbA1c 6.5% to <10.5%, and on a stable dose of metformin are the intended participants.

Not a fit: People using other therapies that alter glucose or insulin metabolism, those with significant comorbidities, or those outside the specified BMI/HbA1c ranges are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, ALN-4324 could improve insulin sensitivity and help people with type 2 diabetes achieve better glucose control with fewer additional medications.

How similar studies have performed: RNAi therapies have shown clinical success in other disease areas, but using an siRNA to improve insulin sensitivity in type 2 diabetes is relatively novel with limited prior clinical evidence.
