Galvus(R)
(vildagliptin), seeking to become a new once-daily oral treatment option
for type 2 diabetes, has demonstrated impressive efficacy, especially in
patients with poor glycemic control, as well as weight loss benefits in
obese patients.
These new findings from Phase III studies were presented today at a
late-breaker session at the 66th Scientific Sessions of the American
Diabetes Association (ADA) meeting in Washington, DC.
The combination of Galvus, a member of the DPP-4 inhibitor class, and
pioglitazone led to an overall 1.9% reduction in HbA1c (a measure of blood
sugar control also known as A1c). Pioglitazone is an insulin sensitizer
known as a thiazolidinedione, or TZD. Two-thirds of people (65%) on Galvus
and pioglitazone achieved the ADA-defined A1c goal of less than or equal to
7% versus 42% of those who achieved this goal on monotherapy (Galvus 42.5%,
pioglitazone 42.9%).
More importantly, a reduction of up to 2.8% in A1c was seen among
patients with poor glycemic control who had the highest mean baseline blood
sugar levels (about 10%) as measured by A1c.
Also in this study, patients over age 65 who were given Galvus and
pioglitazone showed an A1c drop of 2.3% from a mean A1c baseline of 8.4%.
In obese patients, with a Body Mass Index (BMI) equal to or over 35,
patients given Galvus and pioglitazone showed a decline of 2.2% from a mean
A1c baseline of 8.6%.
In a separate head-to-head comparison with rosiglitazone, another
insulin sensitizer, Galvus demonstrated comparable efficacy. Among severely
obese Galvus-treated patients, there was a mean reduction of body weight
greater than 1 kg, with an overall mean difference of 2.8 kg between the
Galvus and rosiglitazone treatment groups.
"These new data underscore the significant efficacy and good
tolerability that have been consistently observed in the robust Galvus
clinical development program," said James Shannon, MD, Head of Development
at Novartis Pharma AG.
"The magnitude of A1c reductions seen with the combination of Galvus
and a TZD is encouraging for patients struggling to reach and maintain
their blood sugar levels. The trial results for Galvus continue to
reinforce the benefits of treating both islet dysfunction and insulin
resistance in type 2 diabetes," Shannon said.
Throughout the Phase III program, Galvus has shown clinically
significant and consistent A1c reductions both as monotherapy and in
combination with other oral and injectable anti-diabetic agents. Galvus has
demonstrated a good tolerability profile in these studies, with no weight
gain overall and an incidence of hypoglycemia (excessively low blood sugar)
and edema (fluid retention) similar to placebo in monotherapy trials.
"As the diabetes epidemic continues to grow worldwide, there is a very
real and urgent need for new ways to help control blood sugar levels in
people with type 2 diabetes," said Julio Rosenstock, MD, Director of Dallas
Diabetes and Endocrine Center at Medical City, Clinical Professor of
Medicine, University of Texas, Southwestern Medical School Dallas and a
lead investigator in the Galvus/pioglitazone trial. "We were pleased to see
the especially steep reductions of glucose in the sub-analysis of patients
with the highest blood sugar levels. However, this high baseline population
represents a difficult to treat group and these patients usually require a
multi-drug strategy to reach glycemic goal."
Galvus was accepted for U.S. regulatory review earlier in 2006. The
submission includes data from clinical trials involving more than 4,300
patients worldwide. Regulatory filings in the EU are planned to be
completed later in 2006.
About the trials
The two trials were highlighted at the ADA late-breaker session as part
of a broad overview of clinical data summarizing the development as well as
overall efficacy and tolerability of Galvus.
The first was a six-month clinical trial evaluating the combination of
Galvus and pioglitazone (Pio) in patients with type 2 diabetes. The study
evaluated 592 patients who had never been previously treated for type 2
diabetes and who had a baseline A1c of between 7.5% and 11%. It involved
four treatment groups: (1) Galvus 100 mg; (2) Pio 30 mg; (3) Galvus 100 mg
+ Pio 30 mg; (4) Galvus 50 mg + Pio 15 mg.
Among patients with baseline A1c of 9% or greater, the combination of
Galvus and Pio produced a 2.8% reduction in A1c. In the overall population,
patients receiving Galvus 100 mg + Pio 30 mg saw a statistically
significant overall reduction in A1c compared to those on Pio alone (1.9%
vs. 1.4%, p < 0.001).
Adverse events were consistent with the individual safety profiles of
Galvus and TZDs. The patients treated with the combination of Galvus and
Pio experienced no significant additional weight gain and less edema
compared to patients taking Pio alone.
The second trial involved 700 patients in a six-month head-to-head
comparison of Galvus (100 mg daily) and rosiglitazone (8 mg once/day).
Galvus reduced blood sugar levels significantly (-1.1%) as measured by A1c,
with no difference between treatment groups. Galvus treatment was not
associated with weight gain overall, while people in the rosiglitazone
group gained on average 1.6 kg. Galvus-treated patients also experienced a
lower incidence of edema (2.5% vs. 4.9%).
The initial results from this trial were presented at an ADA poster
session at 10:00 am EDT on Saturday, June 10 (abstract 557-P).
In an additional subgroup analysis of severely obese patients presented
at the late-breaker session, there was a mean reduction of body weight
greater than 1 kg in the Galvus group, with a mean difference between the
Galvus and rosiglitazone groups of 2.8 kg.
About the "GLORIOUS" mega-trial program
Novartis is committed to developing therapies that will impact the
progression of type 2 diabetes. This was confirmed through the announcement
at the ADA meeting of the "GLORIOUS" mega-trial program, one of the largest
series of outcomes-focused clinical programs conducted among people with
type 2 diabetes. Novartis intends to provide additional details on the
program later in 2006.
About Galvus
In clinical studies, Galvus has demonstrated significant reductions in
blood sugar that were sustained at one year. Galvus is suitable for
once-daily dosing and has been evaluated in clinical trials both as
monotherapy and in combination with other anti-diabetes agents. Galvus is
not associated with overall weight gain, a key benefit for people with
diabetes who struggle to keep their weight under control. The overall
incidence of side effects with Galvus including hypoglycemia and edema was
similar to placebo in monotherapy trials. Overall, the most common side
effects seen in the Galvus clinical trial program were cold/flu-like
symptoms, headaches and dizziness. Galvus lowers blood sugar by targeting
islet dysfunction: It improves the ability of the islet's alpha- and
beta-cells to appropriately sense and respond to sugar in the blood.
About Diabetes
Diabetes currently affects about 195 million people worldwide and is
estimated to grow to more than 330 million by 2025, according to the
International Diabetes Federation.(1) The U.S. Centers for Disease Control
estimates that about 20 million Americans have diabetes.
Type 2 diabetes is a progressive disease where control of blood sugar
deteriorates over time. It is the sixth leading cause of death in the
United States and a major contributor to heart disease, stroke, blindness,
kidney disease and vascular or neurological problems that can result in
amputation.
Islet dysfunction and insulin resistance both contribute to diabetes.
Specifically, islet dysfunction can lead to excess sugar production (via
glucagon from the alpha-cells) and reduced insulin production (from the
beta-cells). Even among people receiving diabetes care, controlling blood
sugar levels is difficult. More than half of those currently taking
medication to manage their diabetes are still not reaching their blood
sugar goals, according to data from the National Health and Nutrition
Examination Survey (NHANES)(2).
