Clinical Trial Summary

Objective: To evaluate the safety and efficacy of Human Insulin rDNA (Insuget) in patients with Type II Diabetes Mellitus.

Study Design: Open-label, prospective, observational, single arm, multi-center, post-marketing surveillance study.

Sample size: The estimated target sample size is n=230. Study duration: 12 months (data lock point will be completion of 6 months' follow-up from the time of last patient's enrollment date)

After recruitment, patient is supposed to have three visits for follow-ups. Visit 1: 4 to 6 weeks of initiation of therapy. Visit 02: At 12 weeks of initiation of therapy. Visit 03: At 24 weeks of initiation of therapy.

• Primary (SAFETY Outcomes):

• Frequency of serious adverse events.

• SECONDARY OUTCOME MEASURES (EFFICACY ENDPOINTS)

• Change from baseline in HbA1c% to the last-observation.

• Change from baseline in fasting plasma glucose to the last- observation on treatment

Ethical consideration:

The ethical approval of study is taken from an independent ethics committee. The study will be conducted in compliance with the protocol, good clinical practices (GCP), the ethical principles that have their origin in the Declaration of Helsinki and the applicable regulatory requirements.

Description:

OBJECTIVE To evaluate the safety and efficacy of Human Insulin rDNA (Insuget) in patients with Type II Diabetes Mellitus.

METHODOLOGY:

STUDY DESIGN:

Open-label, prospective, observational, single arm, multi-center, post-marketing surveillance study.

SAMPLE SIZE As per cited literature, the reported hypoglycemia rate was 41% in patients who underwent treatment of Human Regular Insulin.

Considering 10% increase of hypoglycemia incidence in current study from the reference literature and keeping 95% confidence level, 5% margin of error and 80% power of study, the calculated sample size is n=191. After adding 20% attrition rate, the target enrollment would be n=230.

NUMBER OF SITES Total 04-05 sites.

STUDY DURATION 10-12 months (data lock point will be completion of 6 months' follow-up from the time of last patient's enrollment date)

SAMPLING TECHNIQUE A non-probability consecutive sampling method will be used to screen patients as per study eligibility criteria.

LABORATORY TESTING:

Reputable laboratory is considered for testing of diabetes patients i.e. HbA1c and FBG. The certified clinical lab will be responsible for receiving and analyzing clinical sample.

HbA1c and FBG readings would be recorded within ±10 days of the follow up visit and FBG ±03 day of the follow up visit or average of last three reading in the diary reported by patient, respectively.

STUDY TREATMENT After obtaining consent and baseline assessment, the patient will be advised to start Insuget (Human Insulin rDNA) and will be assessed in follow-up visits as per the defined parameters.

DOSE & FREQUENCY OF STUDY TREATMENT The investigator will recommend the dose of Insuget 70/30 (Local Insulin brand) and/or Insuget N (Local Insulin brand) and/or Insuget R (Local Insulin brand) as per standard clinical practices to meet the daily requirements of study patients.

The drug frequency will be at the discretion of the treating physician. Patients included in the study will be administered treatment according to the standard guidelines.

CONCOMITANT TREATMENT Concomitant treatment for hypertension, dyslipidemia, and other associated diseases will be continued as per the physician's discretion and/or according to the standard guidelines. Similarly, other treatments can be initiated during the course of the study as and when needed. All concomitant medications must be documented.

DATA COLLECTION An electronic data capture system will be used for this study. An electronic database will be designed to record the data required by the protocol and collected by the investigator. All personal data will be coded with a unique number; the researcher will securely keep codes at the research site. Potential participant will have to sign the consent to take part in the study but all personal data collected during the study will be dealt with strict confidentiality and will be used for the research in coded form.

Coded data will be transferred and processed following applicable laws, regulations protecting processing, and transfer of coded data. As per data protection laws and regulations, patients may be titled to access, rectify and ask for the deletion of their personal data via their doctors who are the only person to know the correspondence between the participant number and identity. Personal data will be kept until the publication of the results of the study and will then be archived.

DISCONTINUATION OF TREATMENT Any significant adverse event, which leads to discontinuation from the study treatment. The time and reason for discontinuation will be recorded in the CRF.

DATA MANAGEMENT AND STATISTICAL ANALYSIS Statistical analyses will be performed using SPSS version-22. Mean ±standard deviation will be calculated for continuous variables like age, height, weight, BMI, blood pressure, duration of diabetes, HbA1c and FBS whereas categorical variables will be presented as frequencies and percentages (gender, smoking status, education level, comorbidities, adverse events, etc). Age will be stratified to evaluate the association of reported adverse events with age group and other categorical variable will be assessed through chi-square test. ANOVA will be applied to determine the reduction of HbA1c, FBS, Weight, BMI and Blood Pressure from baseline to 6 months follow-up. A normality test will be done for consideration of parametric or non-parametric application of significance tests. P-value <0.05 will be considered statistically significant.
