Trial Outcomes & Findings for CSTC1 for Diabetic Foot Ulcers Phase II Study (NCT NCT01813305)

NCT ID: NCT01813305

Last Updated: 2022-04-12

Results Overview

Complete ulcer closure is defined as 100% skin re-epithelialization without drainage or dressing requirements confirmed at the coming visits 2 weeks apart. The treatment period is until 12 weeks or up to confirmation of complete ulcer closure. Subjects with complete ulcer closure at Week 12 and confirmed at Week 14 were considered as success.

Participant Flow

The planned sample size was determined to be 80 versus 20 subjects (4:1 ratio) for treatment versus vehicle groups, 100 subjects in total. To ensure the completion of 100 evaluable subjects, around 125 subjects were planned to be recruited. In the actual trial, a total of 137 subjects were screened, with 124 meeting the criteria followed by randomization to CSTC1 group (n = 98) or Vehicle group (n = 26).

SECONDARY outcome

Timeframe: baseline and 24 weeks

Population: All randomized patients who have received at least one dose of study medication.

The proportion of ulcer closure is calculated as (Ulcer size at post-treatment visit - Ulcer size at baseline)/(Ulcer size at baseline). This proportion was then multiplied by 100 to calculate the percentage change in ulcer size for each post-treatment visit. The percentage change in ulcer size for each post-treatment visit are presented.

OTHER_PRE_SPECIFIED outcome

Timeframe: 24 weeks

Population: All randomized patients who have received at least one dose of study medication.

An AE is any untoward medical occurrence in a patient or clinical investigation participant administered a study medication and that does not necessarily have a causal relationship with this treatment. An AE can, therefore, be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study medication, whether or not related to the study medication. AE data was collected from Screening visit to Final visit (up to 24 weeks).

Physical examinations in this study included the following items: general appearance, skin, eyes, ears, nose, throat, head and neck, heart, joints, chest and lungs, abdomen, lymph nodes, musculoskeletal, nervous system, and others. Physical examinations were conducted from Screening visit to Final visit (up to 24 weeks). If at least one of physical examinations was identified in the subject, the subject was included in physical abnormalities calculation.

OTHER_PRE_SPECIFIED outcome

Timeframe: baseline and 12 weeks

Population: All randomized patients who have received at least one dose study medication.

Laboratory examination to be measured in this study consisted of hematology (hemoglobin, hematocrit, RBC, platelet, WBC with differential counts) and biochemistry (Aspartate Transaminase (AST), Alanine Transaminase (ALT), fasting glucose, HbA1c, serum creatinine, blood urea nitrogen (BUN), albumin). The laboratory examinations were conducted at the Screening visit, baseline, and Week 12. Patients' laboratory change from baseline to Week 12 was documented as relieved, unchanged, worsened (MH), or worsened (AE). The "worsened" means that the laboratory values were normal or non clinically significant (NCS) at baseline but change to clinically significant at Week 12. If the worsen situation was found, the clinically significant worsening changes were classified as related to medical history (MH) or adverse events (AE).

Timeframe: baseline and 24 weeks

Population: All randomized patients who have received at least one dose of study medication.

Vital signs measurement consisted of blood pressures, pulse rate, respiratory rate, and body temperature. Among them, blood pressure (systolic/diastolic) were obtained after the subject has been at rest for at least 5 minutes in a sitting position. The vital sign data was collected from Screening visit to Final visit (up to 24 weeks). The mean changes of Final visit to baseline in vital signs were presented (value at 24 weeks minus value at baseline).

OTHER_PRE_SPECIFIED outcome

Timeframe: baseline and 24 weeks

Population: All randomized patients who have received at least one dose of study medication.

Vital signs measurement consisted of blood pressures, pulse rate, respiratory rate, and body temperature. Among them, pulse rates were obtained after the subject has been at rest for at least 5 minutes in a sitting position. The vital sign data was collected from Screening visit to Final visit (up to 24 weeks). The mean changes of Final visit to baseline in vital signs were presented (value at 24 weeks minus value at baseline).

POST_HOC outcome

Timeframe: 24 weeks

Population: All randomized patients who have received at least one dose of study medication.

The proportion of ulcer closure is calculated as (Ulcer size at post-treatment visit - Ulcer size at baseline)/(Ulcer size at baseline). Time to achieve ≥ 50% reduction in target ulcer size was measured from Screening visit to Final visit (up to 24 weeks).

The proportion of ulcer closure is calculated as (Ulcer size at post-treatment visit - Ulcer size at baseline)/(Ulcer size at baseline). A subject who had target ulcer closure ≥ 50% was counted as a responder. The non-responders included subjects whose target ulcer closure size less than 50% before 12 weeks.
