INTRODUCTION 
Diabetes Mellitus (DM) is a common and debilitating disease that also affects the skin.1,2 
Between 30% and 70% of patients with DM, both type 1 and type 2, will present with a 
cutaneous complication of DM. Dermatologic conditions linked with DM vary in severity and 
can be benign, deforming, and even life-threatening.1These skin conditions can offer insight 
into patients’ glycemic control and may be the first sign of DM in undiagnosed patients. 
Recognition and management of these conditions is important in maximizing the quality of life 
and in avoiding serious adverse effects. 
 
DM can be associated with pruritus, more often localized than generalized. Affected areas can 
include the scalp, ankles, feet, trunk, or genitalia. Pruritus is more likely in DM who have dry 
skin or diabetic neuropathy. Cutaneous disorders associated with DM commonly bother and 
cause pain and severely impact quality of life, including interpersonal relationships.1 
 
CeraVe Skincare contains a unique combination of three ceramides. Ceramides are key 
physiologic lipids required for construction and maintenance of the epidermal barrier.

STUDY OBJECTIVES 
To evaluate the safety and efficacy of the CeraVe Hydrating Cleanser and Moisturizing Cream 
for the improvement of dry skin in patients with diabetes mellitus.

INVESTIGATIONAL PLAN 
4.1 
Overall Study Design 
This is a multicenter, open-label, cohort study designed to clinically evaluate the CeraVe 
Hydrating Cleanser and Moisturizing Cream for the improvement of dry skin in patients with 
diabetes mellitus. All subjects meeting inclusion/exclusion criteria will receive unblinded 
product. This is a single cohort study, with no placebo or randomization schedule.  
 
Visit Schedule: 
 
Visit 1 / Day -30 to 0 – Screening* 
Visit 1 or 2 / Day 0 – Baseline*  
Visit 3 / Day 28 (± 5 days) – End of study (EOS) 
 
* Visits 1 and 2 may be combined to occur on same day. 
 
Evaluations include: 
1. Physician-assessed Dry Skin Classification Scale 
2. Physician-assessed Global Aesthetic Improvement Scale 
3. Subject-assessed Dry Skin Classification Scale 
4. Subject satisfaction with treatment outcomes, regimen and product features 
5. Safety will be assessed by monitoring adverse events (AEs) at all study visits

Safety analyses will be performed on the ITT population. The frequency and percentage of 
subjects reporting adverse events (AEs) will be tabulated by preferred terms and further by 
severity and relationship to study product(s). 
 
Efficacy analyses will be performed on the ITT and PP populations, with ITT as the primary 
population and PP supportive.  
 
4.9 
Primary Endpoint 
The primary efficacy endpoints are the Physician-assessed Global Aesthetic Improvement Scale 
and Physician-assessed Dry Skin Classification Scale, at Visit 3. 
 
4.10 Beginning and End of Study 
A subject is considered to be enrolled in the study when he/she has provided written informed 
consent and has received the investigational products. 
A subject is considered to have completed the study after he/she has completed Visit 3. 
A subject is considered to have withdrawn after he/she has withdrawn consent or has been 
withdrawn under the conditions specified in Section 4.11. 
A subject is considered to have been lost to follow-up if he/she cannot be contacted by the 
investigator. The investigator will document efforts to attempt to reach the subject. The end of 
participation for a subject lost to follow-up is documented as the date of last contact. 
Each subject will be monitored for the occurrence of AEs, including serious adverse events 
(SAEs), starting immediately after the subject has received the investigational products. Each 
subject will be followed for safety monitoring until he/she is discharged from the study. 
Follow-up procedures related to AEs or SAEs may continue beyond the end of the study. 
Each subject will participate in the study for approximately 1 month. It is anticipated that the 
duration of this study will be 6 months from the first subject signing the ICF to the EOS visit 
last subject.  
 
4.11 Subject Withdrawal Criteria 
A subject may withdraw from the study at any time for any reason. 
A subject will be withdrawn from the study if his/her safety or well-being is determined to be at 
risk. Withdrawal will be made at the discretion of the investigator or at the subject’s request. 
A subject must withdraw from the study for any of the following reasons: 
• The subject withdraws consent 
• There is a significant protocol violation as determined by the Sponsor or medical 
monitor. 
A subject may be withdrawn from the study for any of the following reasons: 
• Lost to follow-up

4.14.3 Definitions of Terms 
4.14.3.1 Adverse Event 
An AE is defined as any untoward medical occurrence associated with the use of an 
investigational product in humans, whether or not considered product-related as per ICH E2D. 
An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally 
associated with the use of a product, without any judgment about causality. 
 
4.14.3.2 Suspected Adverse Reaction 
A suspected adverse reaction (SAR) is defined as any AE for which there is reasonable 
possibility that the product caused the AE (21 CFR 312.32 (a)). 
 
4.14.3.3 Unexpected Adverse Event 
An AE or SAR is considered unexpected if it is not consistent with the risk information 
described in the labeling for the study products.  
 
4.14.3.4 Serious Adverse Event 
An SAE is defined as any AE or SAR that, in the view of the investigator or Sponsor, results in 
any of the following outcomes (21 CFR 312.32 (a)): 
• Death 
• Life-threatening  
• Inpatient hospitalization or prolongation of existing hospitalization.  
• Persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
• Congenital anomaly/birth defect 
• Required intervention to prevent permanent impairment/damage

4.14.3.5 Mandatory problem reporting 
All AEs must be documented in the CRFs and source documents. The qualified investigator is 
required to report serious adverse events to the study Sponsor within 72 hours of discovery.  
 
4.14.4 Assessment of Adverse Events 
4.14.4.1 Assessment of Severity 
Severity of AEs will be graded according to the following definitions: 
Mild: AE that was easily tolerated 
Moderate: AE sufficiently discomforting to interfere with daily activity 
Severe: AE that prevented normal daily activities 
 
4.14.4.2 Assessment of Causality 
A medically qualified investigator must assess the relationship of any AE (including SAEs) to 
the use of the study product as unlikely related, possibly related, or probably related based on 
available information, using the following guidelines:  
Unlikely related: no temporal association, or the cause of the event has been identified, 
or the study product cannot be implicated based on available information 
Possibly related: temporal association but other etiologies are likely to be the cause; 
however, involvement of the study product cannot be excluded based on available 
information 
Probably related: temporal association, other etiologies are possible, but unlikely based 
on available information. 
 
4.14.5 Reporting Safety Observations 
Any S/AE must be reported to the Sponsor or designee by telephone, email or through the study 
portal (https://medalogik.com) as soon as possible after the investigator or coordinator has 
become aware of its occurrence. The investigator/coordinator must complete an S/AE Form.
