Regulatory Affairs

The regulation of clinical trials in Romania is being determined by EU directives. Regulatory acts are occasionally changing, therefore local expertise is essential. Our aim is to assist you with a broad range of regulatory affairs services that can help you shorten the approval process and therefore the trial duration.

  • Advice on Romanian regulatory procedures (EC and NMA-MD)
  • Preparation and submission of regulatory documents
  • Obtain permission at the local and central levels to conduct clinical trial
  • Preparation and submission of Marketing Authorization (MA) applications
  • Import of drug
  • Provision of official documents, specific procedures and translations
  • Expert Reports

  • Prepare clinical development plan
  • Recruit investigators through our direct contact and in-house investigator database
  • Train investigators and site personnel
  • Study site support
  • Patient recruitment and retention
  • Randomization, repackaging, coding and labeling of investigational drugs
  • Schedule monitoring activities
  • Arrange and conduct steering committee meetings
  • Provide clean and locked data
  • Archiving

Training Courses


All too often, the only teaching of Good Clinical Practice (GCP) investigators receive consists of one or two hours’ refreshment course during an investigators’ meeting for a specific trial. Aware of the importance that all investigators and co-investigators who participate in trials are proficient in GCP, EMA strongly recommends that in-depth, stand-alone courses and respective certification are made available.

The program

Training courses represent cooperation between Tangent CME, a not-for-profit organization, and Craiova University of Medicine, aimed at providing high-quality GCP to investigators, study coordinators, and other participants in clinical trials. The project’s novelty is in its format and its curriculum comprehensiveness, all under the academic sponsorship of a medical school.

Patient Recruitment and Assesment

Drug Development in Mental Illnesses: The Issues
  • Poor understanding of pathophysiology of mental illnesses
  • There exist no validated targets in preclinical drug development stages
  • Go/no-go decisions can only be made after the Proof Of Concept (POC) stage
  • To end the POC stage a sponsor has to spend approximately $50 million
  • About 9-10 compounds are abandoned at the POC stage because of unpredictable lack of efficacy or AE
  • A few POC trials fail due to avoidable faults in clinical trial methodologies or execution
  • Over the last 3 decades the number of PCO failed and false negative trials is increasing and the effect size between active drugs and placebo decreasing
  • Increasing sample sizes and investigators number has proven an expensive and inefficient solution to the high failure rate
  • Factors hypothesized to contribute to study failures are:
    • Poor application of study eligibility criteria
    • Large numbers of raters who achieve low intra-raters correlations
    • High rate of placebo response
    • Incentives for patients’ recruitment speed without incentive for quality

Proposed solutions
  • Reducing the number of raters and improving rater’s training
  • Monitoring raters performance and re-training during the trial
  • Centralized, on-line assessment of eligibility and severity using remote video technologies
  • Taping assessments for review by experts
  • Separating rating and raters from the trial sites

TGD solution: Regional Expert Rating (RER)
  • Core group of full-time raters with basic training in psychiatry or psychology
  • Training in basic assessment instruments (SCID, PANSS, Ham-D, MATRICS, MADRAS, ADAS)
  • Additional trail-specific training
  • Raters, who are not part of the trial site, are assigned to sites based on geographical distribution
  • Patients screened and found eligible by the PI are interviewed in person by the RER
  • The same RER perform severity ratings throughout the trial duration
  • Senior psychiatrist is available to the RER to review eligibility and baseline assessments.
  • Unexpected or unexplainable scores such as abrupt improvements following baseline severity assessment will be adjudicated promptly and dealt with according to the SOP.

RER advantages
  • Suitable for POC trials of small- to medium-size.
  • Easy to implement
  • Transparent to the sponsor and investigators
  • Avoids difficulties which might emerge from patients’ and investigators’ concerns with unfamiliar technologies
  • Cost effective

The above services are governed by TGD’s written Standard Operating Procedures and Technical Guidelines and comply with the ICH Guidelines on Good Clinical Practice (GCP).
