Soliqua: The Insulin-and-GLP-1 Pen, What Its Trials Showed, and How It Differs From Ozempic

Soliqua 100/33 combines insulin glargine with the GLP-1 drug lixisenatide in one daily pen for type 2 diabetes. What the label and the LixiLan trials report on blood sugar and weight, its side effects, and how it differs from Ozempic.

Soliqua is two diabetes drugs in one pen: the long-acting insulin glargine and the GLP-1 drug lixisenatide. It is a once-daily injection for adults with type 2 diabetes, approved in the United States in November 2016, and it is the only way lixisenatide currently appears among the labels on DailyMed. It is not a weight-loss drug, and it is not Ozempic.

This page sets out what the label and the two pivotal trials report. Records were read on 14 October 2026; the label is Sanofi's version effective 18 March 2026.

What is in the pen

Insulin glargine Lixisenatide
What it is Long-acting insulin analogue (the insulin in Lantus) GLP-1 receptor agonist, a 44-amino-acid synthetic peptide
Amount per mL 100 units 33 mcg
Across the pen's range (15-60 units) 15-60 units 5-20 mcg

Source: Soliqua 100/33 label, sections 2.1, 3 and 11.

The fixed ratio is the defining feature: the two drugs move together. The label sets the maximum at 60 units a day, which is 20 mcg of lixisenatide. Under its limitations of use it is not recommended with any other GLP-1 drug, has not been studied with mealtime insulin, and is not for diabetic ketoacidosis. Its approved use is blood-sugar control in adults with type 2 diabetes.

What lixisenatide is. It is a GLP-1 receptor agonist that was also approved alone, as Adlyxin, on 27 July 2016 (BLA 208471). Drugs@FDA still shows that application as "Prescription", but a DailyMed search for lixisenatide on 14 October 2026 returned a single label — Soliqua's. In practice, lixisenatide reaches US patients inside this insulin pen. Lixisenatide's own heart-outcome trial, ELIXA, enrolled 6,068 people who had recently had an acute coronary syndrome: major cardiovascular events occurred in 13.4% on lixisenatide against 13.2% on placebo (hazard ratio 1.02, 95% CI 0.89 to 1.17). That showed it did not raise cardiovascular risk, but not that it lowered it (Pfeffer et al., NEJM 2015). Semaglutide, liraglutide and dulaglutide later gained heart-protection claims; lixisenatide did not.

The two trials on the label

The label rests on two 30-week, open-label trials, both designed — in the label's words — "to show the contribution of the GLP-1 component", so the insulin dosing was matched between arms.

Trial Who Arms HbA1c change Weight change
LixiLan-O (Study A) 1,170 people not controlled on oral drugs Soliqua / glargine alone / lixisenatide alone -1.6 / -1.3 / -0.9 points -0.3 / +1.1 / -2.3 kg
LixiLan-L (Study B) 736 people not controlled on basal insulin Soliqua / glargine alone -1.1 / -0.6 points -0.7 / +0.7 kg

HbA1c from the label, section 14; weight from the trial publications (Rosenstock et al., Diabetes Care 2016;39:2026; Aroda et al., Diabetes Care 2016;39:1972), which the label's clinical-studies section does not report.

Three things to read from that table:

  • The added drop in HbA1c was modest: 0.3 points over glargine alone in LixiLan-O and 0.5 in LixiLan-L. More people reached an HbA1c under 7% on Soliqua (74% against 59% and 33% in LixiLan-O).
  • Weight barely moved. The pen's effect on weight was to cancel most of the gain insulin brings — a 1.4 kg difference in both trials — not to produce weight loss. Lixisenatide alone did better on weight (-2.3 kg) but worse on blood sugar.
  • The final doses were moderate: a mean 39.8 units (13.1 mcg lixisenatide) at week 30 in LixiLan-O and 46.7 units (15.6 mcg) in LixiLan-L.

A registry number that does not resolve. The label gives LixiLan-O's registration as NCT05058147. ClinicalTrials.gov has no record under that number. The trial's actual record — "Efficacy and Safety of Insulin Glargine/Lixisenatide Fixed Ratio Combination Compared to Insulin Glargine Alone and Lixisenatide Alone on Top of Metformin", acronym LixiLan-O, 1,170 participants — is NCT02058147, one digit different. LixiLan-L's number on the label, NCT02058160, resolves correctly. Anyone checking the label against the registry should use NCT02058147.

Side effects

The pooled table covers 834 people on Soliqua across both trials, with a mean of 203 days on treatment:

Reaction (Soliqua, n=834) %
Nausea 10.0
Nasopharyngitis 7.0
Diarrhoea 7.0
Upper respiratory tract infection 5.5
Headache 5.4

The label describes low blood sugar as the most commonly observed reaction with any insulin-containing product and declines to compare its rates across products, because they depend on how hypoglycaemia was defined and on the background treatment. It is the reaction that most separates Soliqua from a GLP-1-only drug. Nausea was lower than with lixisenatide alone: 9.6% against 24% in LixiLan-O (vomiting 3.2% against 6.4%), as reported in the trial publication. The label's warnings also cover pancreatitis, low potassium, kidney injury from dehydration, gallbladder disease, severe allergic reactions and aspiration under anaesthesia — the last shared with every GLP-1 label (see GLP-1 drugs and surgery).

Soliqua against the GLP-1-only drugs

Soliqua Ozempic
Contains Insulin glargine + lixisenatide Semaglutide
Injection Once daily Once weekly
Approved use Type 2 diabetes (blood sugar) Type 2 diabetes; cardiovascular and kidney risk reduction in that population
Weight in pivotal trials Roughly neutral against insulin Weight loss is a reported outcome
Hypoglycaemia Built-in risk (contains insulin) Mainly when combined with insulin or a sulfonylurea

Novo Nordisk sells the equivalent pairing — insulin degludec with liraglutide — as Xultophy 100/3.6, still listed by FDA as a prescription product. No trial has compared Soliqua with Xultophy directly. For the GLP-1-only options in type 2 diabetes see Ozempic for type 2 diabetes and Trulicity; for every molecule in the class, which drugs are GLP-1s.

What is not established

  • Weight loss as a treatment goal. Soliqua was never tested or approved for it.
  • Price. Sanofi's current list price was not quoted here; insurance coverage varies by plan.
  • Head-to-head results against Xultophy or against a GLP-1 drug added to separate basal insulin.

Whether a combination pen, separate insulin and GLP-1 injections, or neither suits a given person is a decision for their diabetes clinician.

Frequently asked questions

Is Soliqua a GLP-1?

Partly. Soliqua is a combination of two drugs in one pen: insulin glargine, a long-acting insulin, and lixisenatide, a GLP-1 receptor agonist. Its label says it should not be used with any other GLP-1 product, because it already contains one.

Is Soliqua the same as Ozempic?

No. Ozempic is semaglutide alone, a once-weekly GLP-1 injection. Soliqua is a once-daily injection of insulin glargine plus a different GLP-1 drug, lixisenatide. Both are approved for blood-sugar control in adults with type 2 diabetes, but Soliqua contains insulin and Ozempic does not, and Ozempic's label carries a cardiovascular-risk claim that lixisenatide's heart-outcome trial did not earn.

Can you lose weight on Soliqua?

The trials did not show much. Against insulin glargine alone, Soliqua users changed weight by -0.3 kg (versus +1.1 kg) in LixiLan-O and -0.7 kg (versus +0.7 kg) in LixiLan-L over 30 weeks. Its effect on weight was mainly to avoid the gain insulin causes. It is not approved for weight management.

What does the 100/33 in Soliqua 100/33 mean?

It is the concentration: 100 units of insulin glargine and 33 micrograms of lixisenatide in every millilitre. Because the two are in a fixed ratio, any change in the insulin amount changes the lixisenatide amount with it; the label states the pen delivers 15 to 60 units, which carries 5 to 20 mcg of lixisenatide.

What are the side effects of Soliqua?

The label's most common reactions at 5% or more were low blood sugar, nausea, nasopharyngitis, diarrhoea, upper respiratory tract infection and headache. Its warnings include pancreatitis, hypoglycaemia, low potassium, kidney injury from dehydration, gallbladder disease and severe allergic reactions.
