5 Milligram (mg) Tirzepatide

Participants received 5 mg of tirzepatide administered as subcutaneous (SC) injection via a single-dose injection pen (SDP) once weekly (QW) for 40 weeks.

The starting dose of tirzepatide was 2.5 mg QW, which increased by 2.5 mg every 4 weeks until the maintenance dose of 5 mg was reached.
