Clinical trial application (CTA) is the pivotal document in drug/biological/medical device licensing. The CTA is submitted to the concerned regulatory authority where the manufacturer intends to market the product. In India, the CTA is submitted to the CDSCO. The application could be for Investigational New Drug, New Drugs Clinical Trial (for obtaining market authorization), Global Clinical Trial (clinical trial in various phases of development as a part of multinational clinical development). The application in Form 44 needs to be submitted along with the necessary documents and data.
The Clinical Trial Protocol is a document that describes the method to carry out a clinical trial. The clinical trial protocol should contain general information, background information, objective and purpose of the trial, trial design, selection and withdrawal of the subject, treatment of the subject, assessment of the efficacy, assessment of the safety, statistics, direct access to source data/document, quality control and quality assurance, ethics, data handling and record keeping, finance and insurance, publication policy, and supplements. At various phases of the clinical trial, the protocol is amended as per the requirement.
An Investigation Broacher (IB) is a document consisting of clinical and non-clinical data on the product under investigation on the human subjects. The purpose of the IB is to provide updated information on the rationale of the study, key features of the protocol, dose, dose frequency, method of administration, physicochemical property of the product, pharmacokinetics, etc., to clinical investigators and others involved in the study. Our in house medical writing team has years of experience in writing, reviewing and updating the IB. We write the IB as per the ICH guidelines and format.
Informed Consent Document is an indispensible part of clinical trial research. It is used in seeking the permission of the subject/patent, wherein the subject confirms his or her willingness to participate in the trial after being informed on every aspect of the trial. We prepare the document as per ICH guidelines and provide translation service on the document as per the native language of the patients/subjects participating in the study.

To ensure transparency in clinical research, increase awareness among the public about the ongoing clinical trial, and comply with stringent mandatory regulatory requirements, the European Federation of Pharmaceutical Industries and Association (EFPIA), the European Medicines Agency (EMA) and the Pharmaceutical Research and Manufacturers of America (PhRMA) have made it clear that the sponsors of clinical trials have to publish the data in clinical trial registries like In India, the entry should be in the Clinical Trials Registry - India (CTRI, database. Moreover, the clinical trial outcome should also be published in peer reviewed journals. These tasks seem to be Herculean for the sponsor company. However, S2M Lifescience has a strong track record in medical writing and communication to support our clients in public disclosure and transparency of clinical trial data. We offer the following services.

  • Reporting the result of the clinical trial (EudraCT,, PharmaCM)

Product Label

Pre-study Documents
Labeling of the product in the pharmaceutical and medical device industry is a multifaceted process. The labels are prepared with great care to avoid errors and mistakes and minimize unwanted expenses of the manufacturer. Many pharmaceutical products are recalled because of errors in packing and labeling. The Market Authorization Holders (MAH) need to frequently update the Core Data Sheet (CDS) as and when there is a new safety, efficacy or warning update on the product. The package inserts and labels are generally filed along with the dossier for Market Authorization Application to the concerned regulatory authorities. Our expert global labeling team prepares and updates the label as per USPI and SmPC guidelines. The team also supports customers in preparing and updating the label as per ROW regulatory requirements.
Quality Control checks of the labels and all regulatory documents are done by our experienced team to ensure quality.
