PREFACE
This Protocol Template is a suggested format for INTERVENTIONAL STUDIES to be
undertaken by the investigators of “Dasman Diabetes Institute” (DDI). The purpose of this
template is to provide a general format for writing a research proposal. Investigators are
encouraged to utilize this format, and modify as appropriate, when developing protocols
for their studies.
It is important to note that instructions and explanatory statements (highlighted) should
be replaced in the original protocol with appropriate text. Section Headings and subheadings might be added as necessary.
The version number and date appear at the footer of each page. While submitting an
amendment to an approved and “FINAL” protocol, you may incorporate the changes in the
protocol and submit the new version. A summary of the changes is required as well.

ABSTRACT OR PRÉCIS
This section should provide a one-page executive summary of approximately 300- 500
words, divided in 3-4 paragraphs. It should summarize all central elements of the
protocol; for instance, rationale, aims and objectives, study design, experimental
methods, study population, expected outcome, and work plan etc. It should stand on its
own and should not refer the reader to points in the description of the study.

and medical data from current literature on the Condition or Disease that
is the focus of the study.
 State what has already been accomplished in the field so far. What were
weaknesses in the previous work? Indicate gaps in the field of
investigation, and how would the proposed study bridge those gaps.
 The results of observational studies and early clinical trials that justify
the study, its design, and the intervention groups should be provided.
 Include any data from animal and human studies relevant to mechanism
of action, effect size, and possible effects of the intervention on selected
outcomes.

SELECTION AND ENROLLMENT OF STUDY PARTICIPANTS
5.1 Eligibility Criteria
This section should define and describe the study population.
Eligibility criteria, often referred to as “Inclusion and Exclusion criteria” are medical
and/or social standards determining whether a person may or may not be allowed
to enter a clinical study. These criteria are based on such factors as age, gender, the
type and stage of a disease, previous treatment history, and other medical
conditions. It is important to note that inclusion and exclusion criteria are not meant
for rejecting people personally, but rather to identify appropriate participants for
the study and to maintain their safety.
The selection and enrollment of participants (who are reasonably representative of
the populations or characteristics under investigation) is the key component of a
successful clinical study.
 Include methods of identifying the Study population, different groups and
arms, the total sample size, and number of participants in each group/arm
(include a table, if appropriate).
 The location of the Study site should be identified. (For example, DDI clinics
and laboratories, affiliated institutions)
5.1.1 Inclusion Criteria
Provide a statement that participants must meet all of the inclusion criteria to
participate in this study; list the criteria; briefly justify each criterion in the list. To
clearly define the study population, list as many criteria as necessary. The following
parameters can be used for setting the inclusion criteria:
 Demographic characteristics such as age, gender, current state of health, past
medical history, the presence or absence of another medical condition etc.
 Baseline physical examination, laboratory results, diagnostic methods,
criteria for classification of current health status. List specific tests,
procedures, and documentation methods.
 Stage of the disease and prior therapy, if any. Consider listing specific prior
treatments. Consider listing the allowable duration of prior therapy for the
Protocol Template, Version # …..,
(RA FORM 001)

Page 6
specific population to be studied (e.g., treatment-naïve, treatmentexperienced or prior-treatment-failed “salvage” participants).
 Ability to understand study procedures and to comply with them for the
entire length of the study.
 If men and women of reproductive capability will be enrolled, indicate
whether contraception is necessary and required. If yes, include details of
allowable contraception methods.
5.1.2 Exclusion Criteria
To clearly delineate the study population, list as many exclusion criteria as
necessary. Then list the criteria and briefly justify each criterion in the list.
The following parameters can be used for setting the exclusion criteria:

Specify health status or any clinical conditions (e.g., Age limit, life expectancy,
co-existing disease or condition, or other characteristics that precludes
appropriate diagnosis, treatment or follow-up in the trial.

Clinical/laboratory indicators of current status, obtained within XX days
prior to randomization. List the specific tests to be performed and the
narrowest acceptable range of laboratory values for exclusion, consistent
with disease and/or safety. Include as many as necessary.

Specify any exclusion related to pregnancy, lactation, or plans to become
pregnant. Specify methods for assessing current status and willingness to
use contraception, if applicable. Include as many as necessary.

Use of [excluded drugs, behavioral interventions, devices, etc.] within XX
days prior to study entry. Treatment with another investigational drug or
intervention (with time frame).

For drug studies: allergy/sensitivity to study drugs or their ingredients.

Cancer and/or other chronic debilitating disease

Current drug or alcohol use or dependence that, in the opinion of the
investigators, would interfere with adherence to study requirements.


STUDY INTERVENTIONS
NOTE: This section mainly applies for Interventional clinical studies. The entire
section can be deleted if the study does not involve an intervention.
 If applicable, provide the details of each study intervention in terms of the type of
intervention, its administration, and duration.
For Example: If the intervention is an Investigational Drug, provide the route of
administration, formulation, dosage, frequency of administration etc. If it is a new
procedure, describe the nature, site, extent, and performance of the procedure.

 State the potential side effects of intervention(s). Include guidelines for
appropriate supportive care, medications, or treatments of the side effects.
 If applicable, state blinding (masking) procedures the study interventions.
 Include instructions for maintaining intervention accountability records.
Ideally, investigators need to develop Standard Operating Procedures (SOPs)
or the Manual of Operations for the study, which provide detailed
instructions for maintaining study records. If such a document is prepared, it
can be referenced instead of providing details.
6.2 Concomitant Interventions
 Concomitant Interventions might be required as an essential component of
the study design or as a consequence of the study outcomes i.e., occurrence
of certain side effects, complications, adverse events etc.
 If necessary, concomitant interventions such as Required Interventions,
Prohibited Interventions, and Precautionary Interventions should be stated.
6.2.1 Required Interventions
Include mandatory modifications to the study interventions, if applicable.
6.2.2 Prohibited Interventions
Include medications, treatments, and the use of certain devices if they are
prohibited while the subject remains on the study.

Precautionary Interventions are meant to enhance the safety profile of study
interventions. If applicable, include precautionary measures to avoid
anticipated side effects, adverse events, poor outcomes, etc.
6.3 Adherence Assessment/Evaluation
