`Lantus®/Apidra® SoloSTAR® help to improve patient satisfaction
`
`Paris, France - June 27, 2011 - Sanofi (EURONEXT: SAN and NYSE: SNY) announced today, at
`
`the 71 st Scientific American Diabetes Association Sessions 2011 , the results of three studies
`showing that people with diabetes using Sanofi insulins Lantus® and/or Apidra® with the insulin
`delivery device SoloST AR® experienced greater treatment satisfaction, better quality of life and
`lower fear of hypoglycemia vs those using a premixed insulin product.
`
`The goal of the first study1, involving 586 patients with uncontrolled type 2 diabetes on oral agents,
`was to evaluate any changes in physical and psychological well-being, diabetes-related symptoms,
`and patient satisfaction with diabetes-related care and treatment over the study period and from
`baseline to endpoint.
`
`It showed that, compared with those on twice-daily premixed 70/30 insulin aspart (premix) , patients
`on the combination of Lantus®- and Apidra®-based regimens experienced better quality of life as
`measured by the Diabetes Quality of Life (DQoL) questionnaire, which evaluates personal
`perception of improvements as a result of treatment:
`• DQoL improved significantly for all groups at all wks; average improvement was greater for
`basal Lantus® (insulin glargine) + 1 prandial Apidra® (insulin glulisine) dose (GLARG+1) and
`stepwise addition of prandial glulisine (GLARG+0-3) vs premix (P::;;0.0002)
`• Compared to the glargine group, patients on premix also showed significantly greater
`hypoglycemic fear from week 12 to study end (P<0.05).
`
`The goal of the second study2, conducted with 220 type 1 and type 2 patients from 32 sites in
`Canada, was to evaluate the change in diabetes treatment satisfaction in people treated with insulin
`glargine. It showed that 96% of patients experienced significant treatment satisfaction upon
`switching to Lantus® SoloST AR® from their previous treatment: Diabetes Treatment Satisfaction
`Questionnaire at 6 months= 12.0 (SD= 5.4), compared to overall satisfaction at baseline.
`
`The objective of the third study, LANSOLEAP3
`, involving 143 adults with either type 1 or type 2
`diabetes in Mexico, was to evaluate satisfaction with the SoloST AR® insulin pen by adult patients.
`It showed that:
`• 83% rated SoloST AR® as excellent
`• 78% found SoloSTAR® easier to use overall, compared with their previous device
`• 87% preferred SoloST AR® to their previous device
`• Of those who had never used a pen device, 83% felt confident about using SoloST AR® on
`the same day they received the pen.
`
`Patient satisfaction is key to improving compliance, and therefore treatment outcomes. As a patient(cid:173)
`centric company focused on the needs of people with diabetes Sanofi is committed to improving
`treatment satisfaction and quality of life.

`
`About the studies
`Polonsky et al (referred as the first study) was a 60-week randomized , open-label study compared
`adding BID premixed 70/30 insulin aspart (PREMIX), basal insulin glargine + 1 prandial insulin
`glulisine dose (GLARG+1), or stepwise addition of prandial glulisine (GLARG+0-3) in 586 patients
`with uncontrolled type 2 diabetes on oral agents. The objective was to evaluate any within- and
`between-group changes in 1) physical and psychological well-being, 2) diabetes-related symptoms,
`and 3) patient satisfaction with diabetes-related care and treatment over the study period and from
`baseline to endpoint. While achieving similar glycemic control and body weight changes , GLARG+1
`and GLARG+0-3 were more effective than PREMIX in FBG reduction and reaching A 1 C <7%, while
`causing less overall hypoglycemia. Patient reported outcomes were measured at baseline, 6, 12, 24,
`36, 48, and 60 weeks to assess overall quality of life, diabetes-specific quality of life (DQoL),
`hypoglycemic fear and adjustment to illness.
`
`Garon et al (referred as the second study) evaluated the change in diabetes treatment satisfaction
`in 220 patients with type 1 or type 2 diabetes treated with Lantus® SoloST AR®. This 6-month
`Canadian, observational, multicenter, prospective registry collected data in 220 T1&T2 Diabetes
`patients
`from 32 sites treated with any combination of unmixed basal
`insulin, oral anti(cid:173)
`hyperglycemic drugs or short-acting insulins who had HbA1c > 7% or HbA1c :5 7% with severe or
`frequent symptomatic hypoglycemia were enrolled
`in the study. Treatment satisfaction was
`measured by using the standard Diabetes Treatment Satisfaction Questionnaire at baseline
`(DTSQs) and after 6 months (DTSQc). Patients acceptance of SoloSTAR® pen was assessed using
`8-item pen use questionnaire having scores from 1 =excellent to 5=very poor. 56 T1 DM and 164
`T2DM pts were on average 39.7 (SD=12.4) and 59.3 (SD=11.0) years old and had BMls of 26.9
`(SD=4.7) and 33.4 (SD=8.0) kg/m2, respectively.
`
`LANSOLEAP (referred as the third study) was a multicenter, prospective, one-arm, six to eight
`week observational study, involving adults with either type 1 or type 2 diabetes (who were either
`insulin users, or insulin na"fve and taking oral medications and candidates for insulin therapy). The
`primary objective was to evaluate satisfaction with SoloST AR®, evaluated by a self-assessment
`questionnaire pertaining to overall acceptance (rating of SoloST AR®) and ease and continuation of
`use. In a second questionnaire, insulin users assessed their preference for SoloSTAR® compared
`with their previous device.
`
`A total of 206 patients were enrolled, with 56 excluded for failing to meet the minimum time of 30
`days between visits. The mean age of the 150 patients whose data could be analyzed was 53.3
`years (range 18-90 yrs); 58.7% were female, 86.6% had type 2 diabetes, 68% had a BMI >25, and
`70% had used insulin previously. The 7 patients who did not inject insulin themselves were
`excluded from the satisfaction evaluation .
`
`About Lantus®
`Lantus® (insulin glargine) is the first 24-hour once-daily basal insulin analog. Lantus® is as effective
`as NPH insulin with similar reductions in HbA10 , but is associated with lower fasting blood glucose
`concentrations. People with Type 2 diabetes experience a consistent and significant reduction in the
`incidence of nocturnal hypoglycemia with Lantus®.4
`
`About Apidra®
`Apidra® is a fast-acting insulin analog of human insulin with a zinc-free molecular structure that
`maintains a rapid onset and a short duration of action, indicated for the treatment of adults with type
`1 and type 2 diabetes. Apidra® offers mealtime dosing flexibility - it can be taken 15 minutes before
`or within 20 minutes after starting a meal, and in a variety of body types, from lean to obese.
