Weight loss

SCALE Obesity and Prediabetes

8% reported weight loss · 2.6% loss with placebo · 56 weeks

3 mg once daily

Adults with obesity, or overweight plus a weight-related condition, without diabetes

Prespecified full-analysis-set analysis using last observation carried forward (LOCF); not a modern treatment-policy estimand FDA-approved for adult weight management (Saxenda)

Safety context

Gastrointestinal symptoms were common; gallbladder events and pancreatitis occurred.

Limitations: Older LOCF analysis differs from modern policy estimands.

Glucose control

LEAD-3 Mono

1.1 percentage-point HbA1c decrease · 0.5 pp decrease with Glimepiride 8 mg daily · 52 weeks

1.8 mg daily

Adults with type 2 diabetes

ITT analysis using last observation on study; least-squares mean adjusted for baseline.

Safety context

Label describes GI adverse reactions; no trial-specific rate extracted.

Limitations: LOCF analysis differs from modern treatment-policy estimands. The corresponding curve is the completer subgroup.

Hormone activity

Mimics GLP-1 activity by activating its receptors, reducing calorie intake.

Saxenda
U.S. weight-management brand, using liraglutide 3 mg daily for adults; pediatric eligibility is defined separately in the label. · injection
Victoza
Originator type 2 diabetes brand in the U.S. and Europe; not the 3 mg Saxenda obesity product. · injection

Novo Nordisk · Originator; manufacturer of Saxenda and Victoza.; Hikma Pharmaceuticals USA · FDA-approved generic liraglutide supplier referencing Victoza; this is a diabetes product, not the Saxenda obesity dose.

Uses, doses and availability depend on the formulation, indication and country. Study doses below describe research; they are not prescribing instructions.

Liraglutide · compound history across indications

Selected early human publications, phase 3 development, and later approvals. The 2002 publication is not a verified first-human-dose date; earlier discovery and studies may be missing.

  1. Publication

    Early human pharmacology results published (NN2211)

    A repeated-dose study of NN2211, later named liraglutide, reported a pharmacokinetic profile supporting once-daily administration. This is a publication month, not a first-human-dose date.

    Agersø et al. · Diabetologia
  2. Publication

    Diabetes dose-ranging results published

    A 12-week randomized dose-ranging trial in 193 people with type 2 diabetes provided early glycemic efficacy evidence.

    Madsbad et al. · Diabetes Care
  3. Study start

    Phase 3 LEAD-3 begins

    NCT00294723 began comparing liraglutide with glimepiride in type 2 diabetes. The registry supplies the study-start month, without an exact day.

    ClinicalTrials.gov · LEAD-3
  4. Publication

    Phase 3 LEAD-3 results published

    The 52-week monotherapy comparison with glimepiride was published online in The Lancet, before the February 2009 print issue and the 2010 U.S. approval.

    Garber et al. · The Lancet · LEAD-3
  5. Approval

    Victoza approved in the U.S.

    FDA approved once-daily liraglutide for type 2 diabetes. Novo Nordisk's announcement followed on January 26.

    Source
  6. Approval

    Saxenda approved for U.S. weight management

    FDA approved the 3 mg daily liraglutide product for eligible adults.

    Source
  7. Publication

    SCALE obesity trial published

    The 56-week randomized liraglutide 3 mg study in adults without type 2 diabetes was published in NEJM.

    Source
  8. Approval

    Saxenda indication expands to adolescents

    FDA added eligible patients aged 12 and older with obesity and weight above 60 kg; this is distinct from the adult chart cohort.

    Source
  9. Approval

    FDA approves a generic referencing Victoza

    Hikma received approval for generic liraglutide injection for type 2 diabetes; this event does not establish approval of a generic Saxenda obesity product.
