Informed consent is "consent given voluntarily by a competent individual who has
received the necessary information, has adequately understood the information and after considering the information, has arrived at a decision without having
been subjected to coercion, undue influence or inducement or intimidation". Informed consent is based on the principle that competent individuals are entitled to choose freely whether to participate in research or not and protects the
individual's freedom of choice and respect for the individual's autonomy. It also protects the subjects' rights. Taking informed consent is a "process" and does not merely consist of a signature
on the consent form. Informed consent is a communication process between the researcher and the participant and starts before the research is initiated and
continues throughout the duration of the study. The investigator or his delegate must discuss all pertinent aspects of the study, answer any queries / doubts,
request consent and then if freely given, documented. The ultimate responsibility is the investigator's.
Informed consent includes a verbal description and discussion of the details of the study including the process of randomization, the components of the study, and
other details mentioned in the checklist below (from Schedule Y 2005) as well as a written consent form
containing all relevant information in simple, non-technical
language in the participant’s vernacular and given to the participant to keep. Adequate time must be provided for the participant to decide on participation.
In case of il iterate participants, a witness is crucial and thumb impressions are
allowed. All signatures should be dated and in case a date is forgotten on the day the consent is taken, it must be retaken on the next visit and dated, with a clear explanation documented in the source document. The investigator MUST NOT date the consent at any point in time; this must be done by the witness in the case
of il iterate participants. In the case of minors, proxy consent from a parent/responsible guardian is permitted and only the parent/responsible guardian may sign the informed
consent form. However, it is mandatory that the minor provides assent (permission) to participate and, if possible, this should be recorded in a separate assent form. If
the participant is incompetent to provide valid informed consent and it is deemed ethically justified to include this person in research, then the proxy consent of a
responsible family member/legal guardian and a witness.

MODEL CONSENT FORM
TITLE OF THE STUDY: A randomized trial comparing adjunctive Modafinil with
placebo for clozapine related adverse effects in people with schizophrenia or
schizoaffective disorder in remission.
You are being requested to participate in a study to see if a drug called Modafinil
can help you with the side effects of increased sleepiness and increased saliva
formation caused by Clozapine that has been prescribed to treat you. These are common side effects of Clozapine and many people given Clozapine suffer from these problems. There are other drugs that can help with these but we do not know of any that can help both at the same time. We hope to include about 70
people from this hospital in this study. What does Modafinil do when taken along with Clozapine?
We have observed that when people who are sleepy in the daytime and sleeping long hours at night on Clozapine are given Modafinil, it keeps them awake and
alert during the day. Modafinil has also helped reduce and even stop the increased salivation that had been a problem with Clozapine treatment. Modafinil
also reduces appetite and many people lose some or all of the weight they had gained while taking Clozapine. However, we have only used this for a few people taking clozapine and we need to use it for more people to be sure it really helps
Does Modafinil have any side effects?
Modafinil has been used by many people all over the world to help reduce
excessive sleep due to a variety of problems, including that caused by medicines. The majority of people have not had any side effects. Some people on Modafinil
have experienced some side effects such as headache, feeling anxious, feeling like vomiting, loose motion and stomach discomfort, but these were usually mild
and temporary. Modafinil does not cause addiction or any problems when it is stopped suddenly. It may cause mild increases in blood pressure but these are usually not serious. It is not known to cause any problems to the heart. Rarely, it can cause a worsening of the psychiatric problem but this has been observed only
at doses higher than what we plan to use in this study. If you take part what wil you have to do?
If you agree to participate in this study, you will be given either one table of
Modafinil to be taken every morning, or an identical looking tablet that does not
contain Modafinil, for a total period of 9 weeks. Using thus dummy tablet will help us be sure that any improvement in your sleepiness or increased saliva formation is
actually due to Modafinil and not due to chance (coincidence) or normal fluctuations in your condition. Neither you nor your doctor will have any choice in
whether you wil get Modafinil or the dummy tablet as this will be decided by a computer program; this is like tossing a coin and you have an equal chance of
getting either tablet. Also, neither you nor your doctor wil know which tablet you are taking till the study is over. All other treatments that you are already on wil be continued and your regular treatment will not be changed during this study. You wil be expected to come for a review to the hospital 2 weeks after starting the
tablet and again after 4 more weeks and finally after a further 4 weeks. Before starting the study and at each visit you will be asked questions about your sleep,
saliva formation, activities, how you feel and about any side effects. Your weight and blood pressure will also be recorded at each visit. No additional procedures or
blood tests will be conducted routinely for this study. If at any time you experience any problems, you wil be expected to report this to
the doctor. You will also be contacted by telephone at least once in between the monthly visits by the doctors in this study who will ask you about any side effects
you are experiencing. Can you withdraw from this study after it starts?
Your participation in this study is entirely voluntary and you are also free to decide to withdraw permission to participate in this study. If you do so, this will not affect
your usual treatment at this hospital in any way. In addition, if you experience any
serious side effects or your condition worsens, the study tablets will be stopped and
you may be given additional treatment. What will happen if you develop any study related injury?
We do not expect any injury to happen to you but if you do develop any side effects or problems due to the study, these will be treated at no cost to you. We
are unable to provide any monetary compensation, however. Will you have to pay for the study tablets?
Both Modafinil and dummy tablets will be given free for a total period of 9 weeks. We wil also reimburse you and one person accompanying you the money that
you spent on travel to come for review (please keep your bus or train tickets) for the visits that you make for this study. Any other treatment that you usually take will continue but the usual arrangements
that you have with the hospital will decide how much you pay for this. What happens after the study is over?
You may or may not benefit from the study drug that you are given. Once the study is over, if the tablet you were given is Modafinil and if it has helped you and
you wish to continue, then your doctor may prescribe it for you. If you were given the dummy tablet and Modafinil has helped the people who took it, then your
doctor wil give you the choice of taking Modafinil. However, this will not be part of
the study and you may have to pay for it. Will your personal details be kept confidential?
The results of this study will be published in a medical journal but you will not be
identified by name in any publication or presentation of results. However, your medical notes may be reviewed by people associated with the study, without your additional permission, should you decide to participate in this study. If you have any further questions, please ask Dr.XXX, Dr. XXX or Dr. XXX (tel: 0471
228XXX/ 228XXX/ 228XX) or email: firstname.lastname@example.org Participant’s name: Date of Birth / Age (in years)
