What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ALN-4324Drug
ALN-4324 will be administered subcutaneously (SC).
PlaceboDrug
Placebo will be administered SC.
| Study group | Role | What they receive |
|---|---|---|

| Placebo | Placebo comparator | Participants will be administered a single dose of placebo. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Baseline in M-value
M-value is measured as the glucose infusion rate at steady state
Measured: Baseline up to Month 3
Secondary outcomes (5)
Frequency of Adverse Events (AEs)
Measured: Up to Month 9
Change from Baseline in M/I
M/I is measured as the ratio of M-value to insulin concentration [I] at steady state
Measured: Baseline up to Month 6
Change from Baseline in M-value
M-value is measured as the glucose infusion rate at steady state
Measured: Baseline up to Month 6
Change from Baseline in Endogenous Glucose Production (EGP)
Both in the basal state and during steady state during the hyperinsulinemic euglycemic clamp (HEC) procedure
Measured: Baseline up to Month 6
Change from Baseline in Hemoglobin A1c (HbA1c)
Measured: Baseline up to Month 6

- Individual data sharing
- Yes: Access to Anonymized individual participant data that support these results is made available 12 months after study completion and not less than 12 months after the product and indication have been approved in the US and/or the EU. Access to data may be declined where there is likelihood a patient could be identified or other feasibility issue, where there is a potential conflict of interest, planned business activities or an actual or potential competitive risk. Data will be provided contingent upon the approval of a research proposal and the execution of a data sharing agreement. Timeframes for data access may vary and can take up to 6 months or more.
